According to statistics in 1995, with the rapid development of large-scale aquaculture, the annual discharge of livestock and poultry manure in China is about 1.73 billion tons, which is 2.7 times that of industrial solid waste in the same period. The livestock and poultry manure without solid-liquid treatment has the following disadvantages: First, the sewage concentration is high. If the direct discharge is not treated, the pollution to the environment is serious. If the standard treatment is carried out, the project investment cost is high and the operation cost is also quite high. Second, the feces Unable to recycle, wasting organic fertilizer resources that can be reused. SUMMARY OF THE INVENTION

When in use, the feces discharged from livestock and poultry enters the inclined vibrating screen from the dirt inlet port. Due to the vibration of the vibrating screen, the feces are dropped into the slag tank through the vibrating screen. During the ramp down along the vibrating screen, most of the sewage falls through the screen of the vibrating screen into the reservoir. In this process, suspended organic matter and other impurities in the sewage can be effectively separated from the sewage to reduce the concentration of sewage and reduce the subsequent treatment pressure of the sewage discharge. At this time, the feces falling into the slag tank passes through the spiral propulsion of the spiral blades of the slag-squeezing device, and the slag is sent into the casing, and after being squeezed, the slag is extruded out of the slag port, and The pressure causes the water extruded from the slag to be discharged into the sewage receiving tray through the drainage on the shell wall. Before the operation is completed, the high-pressure water spray pipe can automatically clean the vibrating screen to prevent the screen from being clogged, ensure the normal operation of the machine, and facilitate management. The moisture content of the manure discharged through the solid-liquid separator is low and loose, which not only facilitates centralized collection and transportation, does not pollute the environment, but also It is beneficial to the processing and utilization of compost and is made into organic fertilizer.

Compared with the existing solid-liquid separator, the invention has the following characteristics:
