Plate and Frame Filter Press and a
Diaphragm Filter Press?
Diaphragm Filter Press , also known as diaphragm Filter press , is a Filter press with a layer of elastic membrane installed between the Filter Plate and filter cloth. It has the advantages of high pressing pressure, good
Corrosion Resistance, convenient maintenance, safety and reliability, etc. It is a common equipment in metallurgy, gas, papermaking, coking, pharmaceutical, food, brewing, fine chemical and other industries, and is widely used in various fields that require
Solid-liquid Separation 1. Introduction of diaphragm filter press
Diaphragm filter press, also known as diaphragm filter press, is a filter press with a layer of elastic membrane installed between the filter plate and filter cloth. It has the advantages of high pressing pressure, good corrosion resistance, convenient maintenance, safety and reliability, etc. It is a common equipment in metallurgy, gas, papermaking, coking, pharmaceutical, food, brewing, fine chemical and other industries. It is widely used in
solid-liquid separation from various fields.
2. What are the differences between a diaphragm filter press and a
Plate And Frame Filter press?
The basic principle and structure of the plate and Frame Filter Press and the diaphragm filter press are the same, the difference is that the filter plate used in the diaphragm filter press is double-sided with a diaphragm cavity, the two Filter Presses
The specific differences between are:
1. The structure of the filter plate is different
The filter chamber of the plate and frame filter press is made of two kinds of filter plates that are staggered and spliced together, one is a solid filter plate and the other is a frame filter plate. Two different filter plates are used in the diaphragm filter press, one
One is a solid filter plate, and the other is a hollow filter plate. The frame filter plate is surrounded by four strips, while the hollow filter plate is cast together with two layers, forming a large gap in the middle of the filter plate.
This is the hollow filter plate.
2. The filter cavity is formed differently
The filter cavity of the plate and frame filter press needs two solid filter plates plus one frame filter plate, and the diaphragm filter press consists of one solid filter plate and one hollow filter plate.
3. Different styles of filter cloth
The diaphragm filter press uses two filter cloths, which are connected in the middle to form a single filter cloth. The filter cloth of the plate and frame filter press is a square filter cloth. Diaphragm filter press
The machine filter cloth adopts the wrapping method, one of the two layers is passed through the small hole in the middle of the filter plate, and then unfolded flat to wrap the filter plate. The plate and frame filter press is directly placed between the filter plates
3. Which is better, plate and frame filter press or diaphragm filter press?
Diaphragm filter press.
The filter plate used by the diaphragm filter press has a diaphragm cavity on both sides. Compared with the filter plate of the frame filter press, the diaphragm filter plate has two filtering surfaces that can move back and forth: the diaphragm.
These movable diaphragms bulge out in the direction of the filter chamber when a pressurized medium (such as compressed air) is introduced behind the diaphragms, that is to say after the filtration process has ended
The filter cake is subjected to high-pressure extrusion again. Equipped with the filtration process of diaphragm filter plate, the water content of the filter cake can be 10-40% lower than that of the ordinary plate and frame filter press, which can save a lot of follow-up
When washing the filter cake, the pressing of the diaphragm can make the amount of washing water less and the effect is better.
