Description

Technical Field

[0001] The present application relates to the technical field of filter presses, and in particular to an automatic mud unloading structure for a filter press. Background Art

[0002] The traditional way of unloading mud is to pull open one filter plate at a time or multiple filter plates at a time. Since the filter press is operated intermittently, the next action can only be carried out after the unloading is completed. The unloading time is long, which leads to a longer operation cycle of the filter press and affects the processing efficiency of the filter press. After the filter plate is opened, the filter cake falls off from the filter chamber by its own weight. However, since the sludge is sticky and the filter cake and filter cloth are pressed together due to high-pressure dehydration, it is difficult to achieve complete unloading only by the weight of the mud filter cake. Manual assistance is required to shovel the cake, and mud unloading is more troublesome. Utility Model Content
