There are many different types of filter plates for filter presses, including steel, glass and, most importantly, plastic, but nowadays most filter plates for filter presses are made of PVC. The filter plates are generally available in side lengths of 250, 320, 450, 630, 800, 1000, 1250, 1600 and 2000 mm and in thicknesses of 45 mm, 60 mm and 80 mm.
The filter plate is an important part of the automatic filter press, and its quality is related to the ultimate role of solid-liquid separation. In the process of selecting a filter press, how can we identify the quality of the filter plate?
First of all, the necessary condition of the filter plate we bought back from the new is that it is basically the same size as the original device, these conditions include, the length, width and thickness of the filter plate, if there is an error is to cause the filter plate to filter press plates manufacturers be placed on the device beam, moving around during filtration, or perhaps even not put up, and then seriously affect the overall operation of the filter press.
The holes inside the filter plate are due to the fact that the filter plate is now made of polypropylene by hot processing and casting, and then the original material of the filter press is heated before it can be used, so the filter plate is easy to form holes in the casting process, and when such holes reach a certain space or number, the filter plate is not a qualified product. It is the depth of depression of the filter plate. The depth of depression of the filter plate determines the workload of each gap cycle of the device (usually the deeper the filter plate, the greater the workload of each time), but not the deeper the better, but the depth of depression of the filter plate exceeds the ability of the filter plate itself to accept strong pressure, the filter plate is easy to fracture or destroy, and can even form a sudden explosion of the filter plate, injuring lives.
If the quality of the filter plate cannot be guaranteed, the quality of the whole device will be even more doubtful. We expect you to investigate more and compare more before buying and choosing the right filter press.
The filter plate of the filter press is made of compound polyethylene plastic. Such a filter plate can be better adapted to the various harsh working conditions of the filter press, thus making the filter press have a longer service life.
There are many reasons for a poor filter plate in a plate and frame filter press. These are some of the common problems. Firstly, the filter press is damaged, creating uneven forces on the filter plate and the pressure of the filter press itself crushing the plate. The damage mentioned here is only caused by unintentional distortion of the filter plate during the use of the filter press, unevenness, unevenness of the edges of the filter plate and tabs or direct edge wear. These damaged filter plates are not easily visible. If this seemingly sick and undamaged filter plate is used with other filter plates, the equipment will provide a powerful filter plate for the duration of the filter press operation. The pressure and time is also long, which will inevitably cause extensive or long-term damage to the other filter plates.
The second is caused by the plate and frame filter press. The filter contains hard and heavy solid particles, which will also cause the filter plates of the filter press to be prone to damage. During the filtration process, such hard and heavy solid particles will accumulate in the filter chamber. As more and more solid particles and various hard particles accumulate, the filter press automatically provides the filter plate. It is well known that the forces of squeezing the filter cake are reciprocal and that the hard particles are unevenly distributed in the filter chamber, which can easily damage the filter plate of the filter press.
