[0002] During the use of the plate and frame filter press, due to various factors such as material viscosity and filter cloth material, the filter cake may not be completely separated from the filter cloth, leaving some filter residue on the filter cloth, thus affecting the filtration efficiency and speed, and may even make filtration impossible. Therefore, timely cleaning of the filter cloth is a key step to ensure the normal operation of the plate and frame filter press;

[0003] At present, there are many methods for cleaning filter press filter cloth, but each method has its advantages and disadvantages. The following is a detailed analysis of the existing cleaning technologies:

[0004] Traditional filter cloth washing method: This method is to remove the filter cloth from the filter plate, soak it in water and then scrub it with a brush. Although it is simple, convenient and effective, it has obvious manpower waste problems. In addition, this method may not be able to completely remove the dirt in the capillaries of the filter cloth, and the cleaning efficiency is relatively low; high-pressure water gun washing method;

[0005] High-pressure water gun flushing method: Use strong water pressure to flush away some of the dirt, but there are also some problems. First, although the surface dirt can be flushed away, the dirt in the filter cloth capillaries is still difficult to completely remove. Secondly, this method uses a large amount of clean water, which not only wastes resources, but also may increase sewage treatment costs. Finally, due to incomplete cleaning effect, repeated cleaning may be required, which increases workload and time costs. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of the automatic cleaning device for filter cloth of the plate and frame filter press of the utility model are:

[0012] Convenience, simplicity and process control: The automatic cleaning device can automatically complete the cleaning of the filter cloth through the preset cleaning program, without frequent manual intervention, which greatly simplifies the operation process. The operator can monitor the cleaning process in real time through the control panel or remote monitoring system, and adjust the cleaning parameters as needed to ensure the cleaning quality and efficiency;

[0013] High-pressure jet cleaning and cleaning effect: The automated cleaning device uses high-pressure jet technology to wash away dirt on the filter cloth through the impact of high-pressure water flow, achieving comprehensive cleaning of the filter cloth. Compared with traditional methods, high-pressure jetting can penetrate deeper into the capillaries of the filter cloth, remove stubborn dirt, and improve the cleaning effect. Efficient and comprehensive cleaning can not only restore the filtering performance of the filter cloth, but also extend its service life and reduce the frequency and cost of replacing the filter cloth;

[0014] Cleaning efficiency and resource utilization: The automated cleaning device can complete the cleaning of the filter cloth in a short time, significantly improve the cleaning efficiency and shorten the production cycle. By accurately controlling the amount of water and water pressure for cleaning, unnecessary waste of clean water can be reduced and the efficiency of water resource utilization can be improved. Wastewater generated during the cleaning process can be recycled and reused, further reducing the impact on the environment. BRIEF DESCRIPTION OF THE DRAWINGS
