The principle of industrial use of box filter press and plate and frame filter press is simply that there is a big difference in oil. According to the statistics of the system, the difference in their principles lies in their specific differences in filtration methods and structures. .
In the industrial use of the box filter press and the plate and frame filter press, let’s talk about their similarities first. The basic principle is to use the structural design of the filter press to form an effective pressure difference environment for the two sides of the medium, while The medium can only allow liquid dialysis to pass through, and can intercept solids to the general of the medium, thus realizing the basic principle of filtration and separation of the filter press. All in all, they all use the barrier separation effect of the filter press medium to realize the essence of solid-liquid separation.
The reason why the plate and frame filter press is different from the box filter press is that they are divided into different categories because of the different handling of the filtration details. To illustrate the difference in the filtering structure between them. Each filter plate of the box filter press has the same opportunity (except the stop plate and the push plate). The top of the filter plate is concave to form a space for storing filter cakes. The two sides are respectively covered with filter cloth and connected in the middle. The cooperation of such a filter plate and filter cloth is squeezed and connected with several filter plates and filter cloths of the same structure, thus forming a filter cloth space like a gourd string, which is the filter chamber of the box filter press.
The plate and frame filter press is different. Its filter plate can be divided into two types, solid filter plate and plate and frame filter plate. There is a feeding channel at the corner of the filter plate to divert the filtrate into the filter cavity. , A hollow plate frame is sandwiched between two solid filter plates, and filter cloth is inlaid on the plate frame, thus forming the filter structure of the plate and frame filter press. This is also the origin of the name of the plate and frame filter press.
For the explanation of the process principles of the box filter press and the plate-frame filter press, I believe everyone will understand the reason for the different performance between them, which is determined by their structure.
