2results about How to "Improve filter press effect" patented technology

The present application relates to sludge treatment technical field, specifically disclose a kind of vertical extrusion type sludge treatment system and method, including cloth mechanism and filter pressing mechanism, cloth mechanism is used to deliver composite filter cloth with sludge clamped to filter pressing mechanism;Filter pressing mechanism includes: filter pressing cavity, for realizing composite filter cloth stacking and filter water;At least one movable filter assembly is arranged in extrusion cavity along vertical direction;Hydraulic mechanism is used to exert vertical pressure on the composite filter cloth stacked in filter pressing cavity.The present application is at least one movable filter assembly arranged in extrusion cavity along vertical direction, and adaptive design is carried out to movable filter assembly, so that in the process of composite filter cloth stacking, not only will not affect filter cloth stacking, and using movable filter assembly separates the support to stacked composite filter cloth, beneficial to the flow of upper layer water to lower layer, and movable filter assembly has extrusion effect to the composite filter cloth on its two sides, can improve filter pressing effect.

The utility model belongs to the technical field of filter pressing devices, discloses a seaweed fertilizer filter pressing device, and aims to solve the problems that an existing filter pressing device is provided with a two-layer filter plate structure and can be used for filtering materials twice, but residual and attached water easily exists in the materials in a one-time filter pressing mode, so that the seaweed fertilizer filter pressing device is difficult to clean. According to the technical scheme, the filter pressing device comprises a box body, a drainage pipe with a stop valve is fixedly installed at the bottom of one side of the box body, a filter cartridge is arranged in the box body, and the front end and the rear end of the filter cartridge penetrate through the box body and are rotationally connected. Filter holes which are uniformly distributed are formed in the periphery of the filter cartridge, an opening is formed in the rear side of the filter cartridge, a turntable is rotationally mounted on the rear side of the filter cartridge, a through material opening is formed in the upper part of the turntable, and two extrusion rollers are rotationally mounted in the filter cartridge. The extrusion rollers can perform multiple times of filter pressing treatment on the filter cartridge, so that the filter pressing effect on materials is improved.
