In addition to its simple and inexpensive design, the chamber filter press is also a powerful and reliable filter press. The type of suspension to be filtered (e.g. mining, chemical or pharmaceutical industry) is irrelevant. In order to meet the different requirements of industry and municipalities, MSE chamber filter presses are designed for this in modular design. The solid and heavy-duty steel filter press frame, which consists of the following main components, forms the basis: Feeding stands with filtrate outlet (head piece), hydraulic stands with locking cylinder (pressure piece), cross beam and side rails on which the individual filter plates are arranged accordingly including filter cloths. The plate pack also consists of uniform chamber plates with a cut-out of 15-50 mm for holding the puncture-proof filter cake. Polypropylene (PP) is used as the chamber plate material in the standard version.
Benefits of Chamber Filter Press
Feed Pressure
Feed pressure is the main factor affecting the filtration effect of chamber filter press. The filter press mainly realizes the function of filtering through the control and adjustment of pressure. So the quality of the pressure system is directly related to the quality of the filtration effect.
Filtration Speed
Filtration speed is another important factor affecting the performance of the filter press. The use speed of the machine should be properly distributed according to different factors such as the concentration and resistance of the liquid.
Filter Area
The filter area of the filter press is directly related to the working rate of the filter press, that is, the processing speed of the filter press. The larger the effective filtration area of the filter press, the higher the ability to filter and separate the mixed liquid per unit time, and the greater the amount of filtration and separation, which also improves the applicable efficiency of the filter press.
The Particle Size Composition Of The Pulp
The impact of the particle size composition of the incoming slurry on the filtration rate mainly depends on the content of fine-grained materials. The higher the content, the larger the specific surface area (S0) of the material, and the lower the filtration speed.
Pulp Concentration
The feeding pulp concentration directly affects the filtration speed, especially in the feeding stage. The higher the pulp concentration, the higher the solid particle content, and the faster the formation of filter cake.
Type of Chamber Filter Press
Plate And Frame Filter Press
The plate and frame filter press is mainly composed of a thrust plate, a compression plate, a filter plate and a filter frame, a beam, a filter medium, a compression device, a liquid collection tank, etc. The plates and frames are arranged alternately, and the two sides of the filter plates are covered with filter cloth. The plates and frames are pressed tightly by a pressing device, and a filter press chamber is formed between the plates and frames. There are holes on the corners of the filter frame and filter plate, which form a complete channel after assembly, which can pass into the suspension, wash water, and lead out the filtrate.
Recessed Plate Filter Press
The structure of the recessed filter press is similar to that of the plate and frame filter press, but the single filter plate of the recessed plate filter press is thicker than the plate and frame filter press plate, and the recessed plate filter press consists of two identical filter plates. When the two filter plates are pressurized, a filter chamber is formed, which is used to store granular objects separated by filter cloth, and the feed hole is placed in the center of the filter plate, which is usually used for materials with larger particles, such as sewage treatment, mineral processing, coal washing, etc. The recessed chamber filter press can withstand a filtration pressure of up to 1.0Mpa and can be easily unloaded by an automatic pull plate. Therefore, it has wider adaptability.
Vertical Filter Presses
The filter plates of the vertical filter press are superposed both horizontally and up and down to form a group of filter chambers, which occupy a small area. It adopts a continuous filter belt; after the completion of filtering, it moves the filter belt and unloads the filter cake, and cleans the filter belt. The operation is automatic, so it is also called filter cloth fully walking automatic filter press.
Membrane Filter Presses
A membrane filter press is a batch filter press equipment used for solid-liquid separation of various slurries. The membrane filter press is equipped with a layer of membrane between the filter plate and filter cloth. During use, when the feeding is finished, high-pressure fluid or gas medium can be injected into the membrane plate/Diaphragm plate, and the entire membrane will bulge to press the filter cake, thereby achieving further dehydration of the filter cake.
High-pressure Round Filter Press
The high-pressure round filter press uses a circular filter plate. This special design makes it an ideal solid-liquid separation equipment in many fields, including the ceramic industry, stone wastewater treatment, kaolin, building materials, etc. In addition, it's high pressure increases processing capacity, improves work efficiency, and reduces moisture in solid materials.
Working Principle Of Chamber Filter Press
Chamber filter press refers to a kind of intermittent operation filtering equipment. The filter chamber of the chamber filter press is composed of two adjacent concave filter plates. It is widely used in petroleum, chemical industry, metallurgy, pharmaceutical, sugar production, mineral processing. , food and sewage treatment and other industrial and mining enterprises, its simple structure, easy to use, suitable for solid-liquid separation of various suspensions.
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.
Chamber Filter Press Treatment Process
Pretreatment: First, the acidic wastewater is collected into a wastewater pool, and alkaline substances (such as lime or sodium hydroxide) are added to the wastewater to neutralize the acidity. The pH value is adjusted to a range suitable for subsequent treatment. Then, flocculants (such as polyacrylamide) are added to aggregate the suspended matter in the wastewater into larger flocs, which is convenient for subsequent solid-liquid separation.
Feed: The pretreated wastewater is pumped into the filter chamber of the filter press. The filter plate of the filter press is covered with filter cloth. The selection of filter cloth needs to be determined according to the acidic characteristics of the wastewater, and usually, a material with strong acid resistance is selected.
Pressure Filtration: The hydraulic system applies pressure to force the liquid in the wastewater through the filter cloth, while the solid particles (i.e., filter residue) are trapped on the filter cloth to form a filter cake. The filtered liquid (filtrate) usually flows into the sump.
Unloading The Filter Cake: After the filtration is completed, the filter press will automatically or manually remove the filter cake. The unloaded filter cake can be dehydrated and dried or sent directly to a dedicated waste treatment facility.
Filtrate Treatment: The filtrate is usually further treated chemically, such as neutralization or precipitation, to remove residual acidic substances and metal ions. The treated filtrate can meet the discharge standard or reuse standard.
Equipment Cleaning: To maintain the filtering effect, the filter cloth needs to be cleaned regularly, usually using high-pressure water or chemical cleaning agents. During the treatment process, some acidic substances will remain inside the filter press, which needs to be cleaned regularly to prevent equipment corrosion and clogging.
How To Clean Up The Chamber Filter Press
The cleaning work occupies a very important part in the maintenance of the chamber filter press and also has a great influence on the work efficiency and results of the chamber filter press. How to do the cleaning work of the chamber filter press is what a lot of people are concerned about. This requires technical content, so I will briefly introduce how to clean up the chamber filter press equipment.
After the chamber filter press equipment stops running, in addition to turning off the power, it is also necessary to clean up the parts that the filter passes through. For the chamber filter press equipment, there are many parts that the filtrate can pass through, and they are all important parts of the equipment. Therefore, we must pay more attention when cleaning. If the equipment is damaged due to the cleaning of the chamber filter press equipment, it will not be worth the loss.
When the filtrate is pumped into the equipment by the feed pump, the first place to flow in is the filter chamber, and the filter chamber is formed by splicing filter plates one by one, so cleaning the filter chamber is equivalent to cleaning the filter plates. So when we clean the chamber filter press equipment, the first thing we need to do is to return the push plate, loosen the filter plate piece by piece, and remove the filter cake from it. The key is to clean up some drainage holes on the filter plate. Prevent the filtrate from air-drying and depositing at these critical locations, causing blockage and damage to the filter plate, so that the chamber filter press equipment will not work properly next time.
In addition to cleaning the filter chamber, the filter cloth also needs to be cleaned. The filter cloth is the direct bearer of the separation between the solid and the liquid of the equipment, so the importance of cleaning the filter cloth can be imagined. After we take off the filter cloth, soak it in the liquid with the opposite pH value of the filtrate, which can reduce the solid particles of the filtrate mixed in the filter cloth. When rubbing with clean water, the solid particles in the filter cloth will also fall off easily, which will eventually make the filter cloth more expeditious and thorough, which is beneficial to the next work of the filter cloth equipment.
