Description

Technical Field

[0001] The utility model relates to the technical field of belt filters, in particular to a belt filter feeding hopper. Background Art

[0002] Belt filter, also known as chain belt filter, is a type of continuous filter and a new type of high-efficiency dehydration equipment. Its operation is similar to that of belt conveyor. It can dehydrate slurry during transportation, separate solid and liquid, and filter residue. There are two types of structures: pressurized and decompressed.

During this process, when the viscosity of the filtered material in the hopper is high or the amount of impurities is high, the efficiency of the hopper during the discharge process will be reduced or even blocked, causing the hopper's discharge speed to decrease, which in turn affects the filtering process of the belt filter.
