Working principle of chamber filter press

Chamber filter press refers to a kind of intermittent operation filtering equipment. The filter chamber of chamber filter press is composed of two adjacent concave filter plates. It is widely used in petroleum, chemical industry, metallurgy, pharmaceutical, sugar production, and mineral processing. , food and sewage treatment and other industrial and mining enterprises, its simple structure, easy to use, and suitable for solid-liquid separation of various suspensions. Next, the editor will introduce the working principle of the chamber filter press to you.

You can find more information on our web, so please take a look.

The working principle of the chamber filter press is that the filter plate is arranged to form a filter chamber (the two sides of the filter plate are recessed, and every two filter plates are combined into a box-shaped filter chamber).

The surface of the filter plate has pits and bosses to support the filter cloth. There are through holes in the center and corners of the filter plate, which form a complete channel after assembly, which can pass in the suspension, wash water and lead out the filtrate. There are handles on both sides of the filter plate, which are supported on the beam, and the filter plate is pressed by the pressing device. The filter cloth between the filter plates acts as a seal.

Under the pressure of the feeding pump, the material liquid that needs to be filtered is sent to each filter chamber, and the solid and liquid are separated through the filter medium (select the appropriate filter cloth according to different industries). A filter residue is formed on the filter cloth until the filter chamber is filled to form a filter cake. The filtrate passes through the filter cloth and flows along the groove of the filter plate to the lower outlet hole channel for centralized discharge. After the filtration is completed, the filter residue can be washed with clear washing water. After washing, compressed air is sometimes introduced to remove the remaining washing liquid. After filtration, open the filter press to remove the filter cake (the filter cake is stored between two adjacent filter plates), clean the filter cloth, and re-press the plate filter to start the next working cycle.

The filter cloth is fixed on the plate frame, which is the main form of the early filter press. The main advantage of the chamber filter press is that it is convenient to replace the filter cloth. The filter chamber of chamber filter press is composed of two adjacent concave filter plates. The filter cloth is fixed on each filter plate. The main advantages of the chamber filter press are high efficiency, and good effect and the filter plate is relatively durable (under the same conditions), but the degree of automation is high, cleaning the filter. The cloth also has an automatic device, and the number of filter cloth replacements is generally not frequent.

The Chamber filter press has become mature dewatering equipment, which is widely used in industry and even in the field of environmental protection and has become important equipment for sewage sludge treatment. The use of this equipment can effectively improve the production efficiency of enterprises. As a chamber filter press company, Kintep has a professional manufacturing team. Our products have a long service life. If you want to learn more about filter presses, then come and pay attention to our website.

An Introduction To Recessed Chamber Filter Presses

The plate and frame press are the most fundamental and the conventional type of filter press. The modern version of a filter press uses plates that have recesses and are therefore called recessed chamber filter presses.

Recessed chamber presses are widely popular and used by various industries, including industrial and municipal wastewater to chemical processing, specifically designed for efficient solid/ liquid separation. It utilizes recessed chamber filter plates that form a series of cavities or replacements for the hollow frames of the plate and frame design between them when clamped together.

Let's discuss the recessed filter press, it's working, and its advantages in detail to better understand them.

What are Recessed Chamber Filter Press and Filter Plates?

Like all the other filter presses, recessed chamber filter presses work by using pressure filtration system technology. These presses have filter plates that hang on a steel frame, and the plates come in gasketed and non-gasketed designs. Gasketed filter plates help eliminate leaks, while non-gasketed plates make filter cloth installation faster as the cloths do not need to be pounded in.

The design of a recessed filter press is similar to that of a plate and frame press, wherein plates hang on a steel frame. The frames act as a clamping device, and both the presses utilize a hydraulic cylinder and pump to open and close the press. Each plate features a recessed area, and when the plates are pushed together; they form a chamber in which solids collect on filter cloths.

Working Principle of Recessed Chamber Filter Press

1. During the filtration procedure, the slurry is pumped into the press through feed, generally in the center of the plate. The solids are distributed evenly in each chamber throughout the process.
2. Solids begin to develop on the filter cloth and start to build a filter cake. The liquid is supposed to pass through the filter cloth selection and onto the drainage surface. The liquid usually exists the plates through corner ports into a manifold.
3. When the right valves are open in the manifold, the liquid exits the press through the filtrate outlet. As the feed pump builds pressure, the solids form within the chambers until they are filled with filter cake.
4. Once the chambers are full of filter cake, the filling cycle is complete, and the filter press is ready to be emptied.
5. The press is then opened, and the plates are moved apart.

Advantages Of Recessed Chamber Filter Presses

A hydraulic power pack in a filter press machine controls the cylinders that help move the plates. It is self-contained and mainly consists of components such as a reservoir, motor, and hydraulic pump. It transfers power from one location to another using fluid.

• One of the main benefits of chamber filter presses is its plate design's ability to feed a large center hole versus a small opening in the corner of the plate. The large holes allow the chamber to fill faster and evenly, with less risk of leakage and clogging.
• Another main advantage of these filter presses is the ability to achieve higher feed pressure with the recessed chamber design. The frame of the recessed chamber plate is connected to the center web.
• The recessed chamber filter press has got dry operation because of the gaskets or the latex edging on the cloth of a non-gasketed plate.

Recessed chamber filter presses and plates are effectively used in various industries. The filter press applications for this type of filter press include industrial wastewater, municipal wastewater, mining and energy, metal finishing, chemical processing, power, fabrication works, and much more. These filter presses hold various advantages over other types and are relatively easy to empty filter cakes. Also you can read our blog about Advantages and Process of Automatic Filter Presses.
