The temperature that has a great influence on the operating state of the filter press is the temperature of the filtrate. The temperature of the filtrate directly affects the filtration power of the filter press and whether the filtration can operate normally. When the temperature of the filtrate exceeds the design temperature of the filter press and the temperature of the filter plate, it directly leads to the deformation of the filter plate of the filter press, or reduces the acid and alkali resistance of the filter plate, or accelerates the corruption and deterioration of the filter plate.

As one of the filtration equipment often used in urban factories, the chamber filter press can help us to carry out effective perfibrillation filtration, so that merchants and manufacturers can obtain better water sources and related raw materials. As more and more groups begin to widely use chamber filter presses, the purchase of chamber filter presses and other information have attracted everyone's attention.

It is important to know that many manufacturers are now using chamber filter presses, using such equipment for filtration and concentration. Due to the fact that there are many different brands of chamber filter presses on the market, it is difficult for many consumers to choose. Let's listen to the basic introduction of professionals to the purchase of chamber filter presses.

First of all, before purchasing a chamber filter press, you must understand your actual needs, relevant use conditions and environmental characteristics. Now there are many models and categories of chamber filter presses on the market, and if you buy unsuitable equipment, you will not only be unable to meet your own needs, but also bring certain economic losses.

Secondly, when purchasing a chamber filter press, the standard of solid content of mud cake should also be considered. To put it simply, it is actually one of the elements of our own operation and operation. The raw materials used in different industries and projects are different, so that there is a difference in the solid content of the mud cake that needs to be faced.

Not only that, now different brands of chamber filter presses, the materials, filter plates, filter cloths and other auxiliary devices used are different. Remember to pay attention to aspects such as the corrosion resistance and tensile strength of these auxiliary devices. High-quality equipment also needs to be supplemented by high-quality spare parts.

In addition to these, it should also be considered whether the way the filter plate is moved can meet the needs of the consumer for later operation.

Now there are many brands of chamber filter presses on the market, and we must remember not to blindly pursue low ** in the purchase process. Because high-quality equipment requires a certain cost investment and meticulous processing of lead. And the cost will naturally be higher.

Performance and filtration effect are the main factors that everyone should pay attention to when purchasing a chamber filter press.

With the rapid development of the industrial industry in the 21st century, we can find that businesses and consumers in different fields and industries have begun to introduce different models of chamber presses, which in turn has attracted the attention of the public. Before purchasing a chamber filter press, you can learn more about the relevant knowledge, which can help you choose the right chamber filter press for yourself.

The two models of plate and frame filter press and belt filter press are quite mature models, and the two models are widely used in urban sewage, pharmaceutical and pharmaceutical, petrochemical, food processing, metallurgy, mining and other industries.

The different structures of the two models also lead to the different filtration methods of the two models, and the working process of the plate and frame filter press is: feed pump feeding-filtration-pressing material-discharge. Now in order to get rid of the manual unloading of the old model, the automatic control does not need manual guarding.

Compared with the belt filter press, the single filtration time is longer, and it belongs to the intermittent work type. However, the water content of the treated sludge is low and the filtration effect is good.

Belt filter press: The belt filter press can work continuously, and the processing capacity of materials per unit time is large (the treatment capacity is not much different from the plate and frame filter press in the case of the same specification), and it is used more in large sewage treatment plants or water plants. However, because the moisture content of the treatment is high, it needs to be reprocessed in the later stage, so many users have slowly replaced the plate and frame machine, and the maintenance of the machine is inconvenient in the later stage.

The difference between chamber filter press and plate and frame filter press:

Plate and frame filter press is a kind of filtration equipment with intermittent operation of pressurized filtration, it is composed of a compression part, thrust plate, compression plate, beam, composed of a frame, all filter plates and filter frames are alternately superimposed on two equal support horizontals, all filter plates and filter frames have liquid passage channels on the corresponding parts, which are used to introduce suspension or discharge liquid, all filter plates have the same sealing surface on both sides as the filter frame, and the filter cloth is sandwiched between the plate and the frame sealing surface, and becomes the gasket of the seal plate and the frame-shaped sealing surface, A filter press consists of a number of parallel filter chambers, each with a filter cloth layer on both sides that prevents the solid particles in suspension from passing through and allows the filtrate to penetrate, and the total filtration area of these filter plates represents all the production capacity of the filter press.

The plate-and-frame filter press is composed of a filter plate and a filter frame, which can withstand a low filtration pressure (usually less than the size of each filter press according to the size of the area, and the number of plates and frames is also different, the plate-and-frame filter press is generally used for the filtration of materials containing less particulate objects, and is often used for the filtration of fine products, which can be filtered by adding filter paper on the back of the filter cloth.

The single filter plate of the chamber filter press is thicker than the plate and frame filter plate, that is, the chamber filter press is formed by the combination of two identical filter plates, and a filter chamber is formed between the two filter plates when pressed to store the granular objects isolated by the filter cloth, and the feed hole is placed in the filter plate, which is generally used for materials with more granular objects, such as sewage treatment, mineral processing, coal washing and other industries, and the characteristics of the chamber filter press are that it is not suitable to cause the bias of each filter chamber, so that the filter plate should not be damaged, the filtration speed is fast, the slag discharge is convenient, the filtration pressure is large, and the liquid content of the filter cake is lowIt can withstand filtration pressures up to MPa, is easy to automatically pull plate discharge, and has a wider range of adaptation, allowing for the manufacture of the largest filter press. Both plate-and-frame and chamber filter presses can realize two kinds of open flow and underflow, which can be divided into washable type and non-washable type according to the filter cake washing method.

Washable type is the replacement between the washing liquid and the filter cake, the diffusion process after filtration of the washing liquid can further wash out the required products contained in the filter cake and the unwanted waste liquid, the filter cake washing method is divided into clear flow washable, undercurrent washable and in line with the washing type (also known as two-way cross washing type). If you choose a non-washable type, you can only filter it, not wash it.

As questioned: What is the essential difference between plate and frame filter press and chamber filter press?

The second difference between the two is that compared to the plate filter press, the chamber filter press has a lower moisture content, faster speed and higher efficiency.

To add: the plate and frame filter press has a tendency to be replaced by the chamber filter press, but there is also an advantage that the chamber filter press does not have, that is, it is very convenient to replace the filter cloth.

Jiangsu Xingxin separation equipment manufacturing.

The frame of the filter plate is different:

The plate frame is two plates + one frame to form a filter; The chamber filter plate is a filter chamber formed between 2 filter plates.

Then there is the difference between the thickness of the cake and the difference in feeding pressure.

The chamber filter press is composed of two adjacent concave filter plates arranged to form a filter chamber (the two sides of the filter plate are recessed, and every two filter plates are combined to form a compartment-shaped filter chamber). The surface of the filter plate has grooves, and its protruding part is used to support the filter cloth, which is fixed to each filter plate.

The plate and frame filter press is composed of a flat filter plate and a hollow filter frame arranged alternately to form a filter chamber. The surface of the filter plate has grooves, and its protruding part is used to support the filter cloth, and the filter cloth is fixed on the hollow filter frame (plate frame).

The box plate frame is connected to the board, or the board with rubber is connected to the ordinary version; Plate-and-frame filter presses are connected to each plate and each frame. There is no difference in appearance. The volumetric chamber type of the filter chamber is generally larger than that of the plate and frame type; When disassembling and washing the filter cloth, the chamber type is more time-consuming than the plate and frame type.
