Description

Technical Field

[0001] The utility model relates to the technical field of filter cloths, in particular to a filter cloth used for a filter press. Background Art

[0002] The filter press is provided with a filter plate and a filter cloth. The filter cloth is generally designed to be two pieces, and the central areas of the two pieces are provided with through holes, and a cylindrical filter cloth is connected to the through holes. When installing, the filter cloth on one side is first rolled into a cylindrical shape, passed through the center of the filter plate, and the two pieces of filter cloth are placed on both sides respectively, and the cloth strips preset on the top of the two pieces of filter cloth are tied together to complete the installation. However, during the production, storage and transportation of this filter cloth, the cylindrical filter cloth in the central area of ​​the filter cloth is piled together, which will cause the central area to be high and the surrounding edge areas to be low when several filter cloths are stacked together.
