Technical Field

The utility model relates to a filter cake collecting device of a filter press, and belongs to the technical field of filter presses.

Background

After each filtration of the filter press is finished, the filter plates are required to be pulled apart from each other, so that filter cakes formed between the filter plates are discharged by self gravity. At present, in order to facilitate timely collection and transportation of the discharged filter cakes, a guide hopper and a conveying belt are usually arranged below the filter press.

The width of the conveyor belt is limited, and meanwhile, the filter cakes are gradually gathered in the process of falling along the guide hopper and then fall on the conveyor belt in a centering manner, so that the guide hopper is generally arranged in a structure with a large upper opening and a small lower opening. In the actual working process, the large filter cake is found to be easy to block in the small opening section of the guide hopper in the process of falling along the guide hopper, and workers are required to break the large filter cake by means of tools.

The foregoing is not necessarily a prior art, and falls within the technical scope of the inventors.
