PLATE AND FRAME FILTER PRESS VS. RECESSED CHAMBER FILTER PRESS

Plate and Frame

WHAT IS A PLATE AND FRAME FILTER PRESS?

A plate and frame filter press is a type of filtration equipment used to separate solids from liquids. It consists of a series of rectangular plates and frames with filter cloth or filter paper in between them.

Goto BRIGHT to know more.

The liquid to be filtered is pumped into the press and flows through the spaces between the plates, while the solids are trapped in the filter cloth or paper. The plates and frames are then separated to remove the filtered solids, and the process is repeated.

The size and shape of the plates and frames, as well as the materials used, can vary depending on the specific application. Plate and frame filter presses are commonly used in industries such as chemical processing, food and beverage, pharmaceuticals, and wastewater treatment. They are particularly useful for filtering large volumes of liquid quickly and efficiently.

PLATE AND FRAME FILTER PRESS DESIGN OVERVIEW

Plate and frame filter presses consist of a series of rectangular plates and frames arranged in a stack, with a filter cloth or filter paper in between each plate and frame. The plates and frames are typically made of materials such as stainless steel, cast iron, or plastic, depending on the application.

The plates and frames are connected to a hydraulic cylinder, which is used to open and close the press. When the press is closed, the plates and frames form a series of chambers, with the filter cloth or paper forming the bottom of each chamber. The liquid to be filtered is pumped into the press, and flows through the filter cloth or paper into the chambers, while the solids are trapped on the filter medium.

The plates and frames are designed to hold the filter medium in place and to allow the filtered liquid to flow out of the press. There are typically two types of plates used in a plate and frame filter press: solid plates and filter plates. Solid plates do not have any openings, and are used to support the filter medium. Filter plates have channels or holes that allow the filtered liquid to flow out of the press.

Plate and frame filter presses can be operated in either a batch or continuous mode. In batch mode, the press is filled with the liquid to be filtered, the filter cake is removed, and the process is repeated. In continuous mode, the liquid is continuously pumped into the press, and the filter cake is continuously removed.

Plate and frame filter presses are versatile and can be used for a wide range of applications, including solid-liquid separation, clarification, and purification. They are commonly used in industries such as chemical processing, food and beverage, pharmaceuticals, and wastewater treatment.

HOW DOES A PLATE AND FRAME FILTER PRESS WORK?

A plate and frame filter press works by using a combination of pressure and a filter medium (usually a filter cloth or filter paper) to separate solids from liquids. The basic process is as follows:

1. The plates and frames are arranged in a stack, with a filter medium in between each plate and frame. The plates and frames are then connected to a hydraulic cylinder that is used to open and close the press.
2. The liquid to be filtered is pumped into the press and flows through the filter medium into the chambers formed by the plates and frames. As the liquid flows through the filter medium, solids are trapped on the filter cloth or paper, forming a filter cake.
3. Once the press is full, the hydraulic cylinder is activated to close the press, applying pressure to the filter cake. The pressure helps to remove more liquid from the filter cake, resulting in a drier cake.
4. The filtered liquid then flows out of the press through channels or holes in the filter plates, and is collected in a separate container.
5. Once the filtration process is complete, the hydraulic cylinder is used to open the press, and the filter cake is removed from the filter medium.
6. The process is then repeated, with the plates and frames being reassembled with fresh filter medium, and the liquid to be filtered being pumped into the press.

Plate and frame filter presses are efficient and effective for separating solids from liquids, and are commonly used in industries such as chemical processing, food and beverage, pharmaceuticals, and wastewater treatment.

ADVANTAGES OF THE PLATE AND FRAME DESIGN

The plate and frame filter press design offers several advantages, including:

1. Versatility: Plate and frame filter presses can be used for a wide range of applications, including solid-liquid separation, clarification, and purification.

Overall, the plate and frame filter press design offers a versatile, efficient, and cost-effective solution for a wide range of solid-liquid separation applications.

Recessed Chamber

WHAT IS A RECESSED CHAMBER FILTER PRESS?

A recessed chamber filter press is a type of filter press used for solid-liquid separation. It is similar in design to a plate and frame filter press, but with some key differences.

In a recessed chamber filter press, the filter plates are recessed, or indented, on both sides. The filter plates are arranged in a stack, with a filter cloth or filter paper in between each plate. The plates are connected to a hydraulic cylinder that is used to open and close the press.

The liquid to be filtered is pumped into the press and flows through the filter cloth or paper into the recessed chambers formed by the filter plates. As the liquid flows through the filter medium, solids are trapped on the filter cloth or paper, forming a filter cake.

Once the press is full, the hydraulic cylinder is activated to close the press, applying pressure to the filter cake. The pressure helps to remove more liquid from the filter cake, resulting in a drier cake.

The filtered liquid then flows out of the press through channels or holes in the filter plates, and is collected in a separate container.

Once the filtration process is complete, the hydraulic cylinder is used to open the press, and the filter cake is removed from the filter medium.

Recessed chamber filter presses are commonly used in industries such as wastewater treatment, mining, and chemical processing. They are particularly useful for filtering slurries and other materials that have a high solids content, as the recessed plates help to retain the filter cake and prevent it from becoming dislodged during the filtration process.

RECESSED CHAMBER FILTER PRESS DESIGN OVERVIEW

The design of a recessed chamber filter press includes the following components:

1. Filter Plates: The filter plates used in a recessed chamber filter press are typically made of plastic, cast iron or stainless steel, and have a recessed area in the center. The filter plates are arranged in a stack and connected to a hydraulic cylinder that is used to open and close the press.
2. Filter Cloth: A filter cloth is placed on both sides of each filter plate. The cloth is made of materials such as cotton, polyester or polypropylene, and is used to retain the filter cake.
3. Feed pump: A feed pump is used to pump the liquid to be filtered into the press.
4. Filtrate outlet: The filtered liquid flows out of the press through channels or holes in the filter plates and is collected in a separate container.
5. Sludge discharge: Once the filtration process is complete, the filter cake is removed from the press. The filter cake is discharged by opening the press, and can be collected in a container or conveyed to a further processing step.
6. Hydraulic system: The filter plates are connected to a hydraulic cylinder that is used to apply pressure to the filter cake during the filtration process. The hydraulic system is operated by a control panel.

The recessed chamber filter press design is particularly effective for applications where there is a high concentration of solids in the liquid being filtered. The recessed plates prevent the filter cake from dislodging during the filtration process, resulting in a drier cake and higher filtration efficiency. Additionally, the recessed chamber design allows for a higher filter cake capacity, resulting in longer operating cycles and reduced maintenance costs.

HOW DOES A RECESSED CHAMBER FILTER PRESS WORK?

1. Preparation: The filter plates are stacked together with filter cloths placed between each plate. The stack is then connected to a hydraulic cylinder that will be used to open and close the press.
2. Filling the press: The liquid to be filtered is pumped into the press and flows through the filter cloths into the recessed chambers of the filter plates. As the liquid passes through the filter medium, solids are trapped on the cloth, forming a filter cake.
3. Application of pressure: Once the press is full, the hydraulic cylinder is activated to close the press. This applies pressure to the filter cake, squeezing out additional liquid and resulting in a drier cake. The pressure is typically maintained for a set period of time, allowing the filter cake to be further compacted and more liquid to be removed.
4. Filtration: The filtered liquid flows out of the press through channels or holes in the filter plates, and is collected in a separate container. The filtration process can continue until the press is full and no more liquid can be pumped into it.
5. Unloading the filter cake: Once the filtration process is complete, the hydraulic cylinder is used to open the press, and the filter cake is removed from the press. The filter cake can be discharged by gravity or by mechanical means, such as a scraper or conveyor.
6. Cleaning: Once the filter cake is removed, the press is cleaned by washing the filter cloths and plates with water or a cleaning solution. The press can then be reassembled and used for another filtration cycle.

Overall, a recessed chamber filter press is an efficient and effective way to separate solids from liquids. Its unique design helps to retain the filter cake and allows for a higher capacity of solids to be filtered, making it ideal for applications with a high concentration of solids. The application of pressure also results in a drier filter cake, reducing the amount of liquid that needs to be further processed or disposed of.

ADVANTAGES OF THE RECESSED CHAMBER DESIGN

The recessed chamber filter press design has several advantages over other types of filter presses. Here are some of the main advantages:

1. Higher filtration efficiency: The recessed chamber design allows for a higher filtration efficiency compared to other types of filter presses.

Introduction of Recessed Plate Filter Press

A recessed plate filter press is a type of filtration equipment that is used to separate solid particles from liquids. It works well for different types of suspensions. This version of a press filter uses plates that have indentations.
The structure of the chamber filter press is similar to that of the plate and frame filter press, but the filter plate of the recessed plate type filter press is thicker than that of the plate and frame filter press. This means that it can bear higher feeding pressure. The recessed chamber filter press consists of two identical filter plates.

When the two filter plates are pressurized, a filter chamber is formed. The feed hole is in the center of the filter press plate. It is used for materials with large particles, such as sewage treatment, ore dressing, and coal washing. The concave plate filter press can handle pressures up to 0.6MP/1.4 MPa. It can also easily remove the filter cake using automatic pulling plates. This makes it more versatile.

It is also an advanced mechanical product that separates solid and liquid materials. It has five main parts: the frame part, the filter part, the pull plate part, the hydraulic part, and the electrical control part.

Recessed Plate Filter Press Working Principle

1. The material is pumped into the filter press through the feed, and the solids are evenly distributed in the filter chamber. The solids begin to collect on the filter cloth, and over time, they form a filter cake on the filter press cloth.
2. Filtrate usually exits the filter plates through corner ports and enters the manifold. When the correct valve in the manifold is open, the filtrate leaves the filter press through the outlet.
3. As the filter presses build up pressure, solids collect in the filter chamber until the filter cake is completely filled. The filling cycle is complete when the filter chamber is full of filter cake. Then, the press is turned on, the filter press plate is moved, and the filter cake falls into the filter cake hopper.

Difference Between Plate and Frame Filter Press and Recessed Chamber Filter Press

1. Feeding position: The most common way to feed the chamber filter press is from the middle, and some older equipment uses the middle-upper method or corner feeding. The plate and frame filter press usually uses corner feeding.
2. Filter press plate structure: The filter plate of the recessed plate filter press is an essential filter plate. The plate and frame filter plates are made up of two parts: a plate and a frame.
3. How automated is it? The chamber filter press can operate automatically, but the plate and frame filter press cannot.

Advantages of Recessed Plate Filter Press

1. Feed through the center hole to fill the filter chamber faster and more evenly. This reduces the risk of damaging the filter plate due to uneven pressure.
2. You can achieve higher feed pressure with the alcove design. This design prevents the filter plates from bending under high pressure.
3. Cake release is easier with concave plates. When using a plate and frame filter press, the filter cake may not be released as quickly and may require more steps to remove.
4. The machine is designed with a combination of mechanical, electrical, and hydraulic components, making it easy to use, maintain, and operate.
