Description

Technical Field

[0001] The utility model relates to the technical field of sludge filter press, in particular to a sludge filter press for sewage treatment. Background Art

[0002] In sewage treatment, a sludge filter press is needed to separate sewage and sludge. In the prior art, a conveyor belt is usually used to transport the sludge, and a plurality of pressing rollers are combined to repeatedly press the sludge to squeeze and dehydrate the sludge.

[0003] For example, the patent with publication number CN117602792A discloses a belt-type sludge filter press. Specifically, the first motor drives the corresponding transmission roller to rotate, and then the transmission roller drives other transmission rollers to rotate through the filter press belt. The filter press belt runs to transport the sludge, and the water flows down from the filter press belt to the filtering mechanism. The second motor drives the rolling roller to rotate and the rolling belt to run. When the sludge passes through the rolling roller, the rolled roller and the rolling belt cooperate with the filter press belt and the rolling plate to squeeze out the water, which is sent out from the desludging plate. The water that flows into the filtering mechanism is filtered and sent to the cleaning mechanism to clean the filter press belt (see its attached Figure 2 );

[0004] However, the sludge is transported to the space between the rolling belt and the rolling plate through the filter press belt, and a certain gap needs to be left between the filter press belt and the rolling belt for the sludge to be input for filtration. Furthermore, in the presence of the gap, the rolling plate is fixed to the bottom of the filter press belt, which may result in insufficient filtration. However, if no gap is set, or the gap is too small, it is easy to cause the sludge to fail to be input or to flow back after input.

[0005] Based on the above description, there is an urgent need for a sludge filter press for sewage treatment that can continuously transport, does not flow back, and has a good filtration effect. Utility Model Content
