Solid-liquid separator for thick slurry

The invention relates to the technical field of solid-liquid separation of thick slurry, and provides a solid-liquid separator for thick slurry. The filter cartridge is rotationally arranged on the rack, two ends of the filter cartridge are provided with a feed port and a discharge port, the side wall of the filter cartridge is provided with a filter gap, and the width of the filter gap is sequentially reduced outwards from the center line of the filter cartridge; the blades are spirally arranged on the inner wall of the filter cylinder, and after the filter cylinder rotates, the blades are used for pushing materials from the feeding port to the discharging port. By means of the technical scheme, the problem that solid excrement flows out of a filter screen in the prior art, and consequently excrement resources are wasted is solved. 本发明涉及浓浆固液分离技术领域，提出了浓浆固液分离器，包括：机架；滤筒，转动设置在机架上，滤筒两端具有进料口和出料口，侧壁具有过滤间隙，过滤间隙宽度由滤筒中心线向外依次减小；叶片，螺旋设置在滤筒内壁上，滤筒转动后，叶片用于从进料口向出料口方向推送物料。通过上述技术方案，解决了相关技术中固体粪便从滤网中流出，从而造成粪便资源的浪费的问题。
