Abstract

The invention discloses a vacuum suction-type screw-extrusion solid-liquid separation system. The vacuum suction-type screw-extrusion solid-liquid separation system comprises a screw extruding mechanism, a driving mechanism, a sealing box body, a vacuumizing machine, an airtight water tank and a continuous liquid discharging mechanism, wherein the screw extruding mechanism is connected with a continuous feeding mechanism and a continuous solid discharging mechanism, the driving mechanism is used for providing the rotation power, the screw extruding mechanism is sealed inside the sealing box body, the vacuumizing machine is communicated with the sealing box body through a pipeline and used for providing vacuum suction force to the vacuum suction-type screw-extrusion solid-liquid separation system, the airtight water tank is connected onto a pipeline between the sealing box body and the vacuumizing machine and used for collecting the liquid discharged from the screw extruding mechanism, and the continuous liquid discharging mechanism is arranged on the airtight water tank. By utilizing the integral vacuum suction principle, the vacuumizing machine which is arranged at the rear end is used for providing the vacuum suction force to the entire internal space, the reliability is high, the flow is optimized, the continuous suction function, the continuous solid / slag discharging function and the continuous liquid discharging function can be realized, the sewage waste treatment time is effectively saved, and the time cost and the labor cost can be greatly saved.

Description

technical field [0001] The invention relates to the field of waste treatment, in particular to a vacuum suction type screw extrusion solid-liquid separation system adapted to complex working conditions. Background technique [0002] The existing method of treating sludge is mainly to filter and dedry it and then fill it with fertilizer. To treat the slag in septic tanks or biogas digesters, it is first extracted for pretreatment, and then filtered and dedried to separate solid substances from liquid substances. , convenient transportation handling. However, due to structural design and principle factors, the existing treatment equipment can only treat waste with simple working conditions, such as relatively simple sludge, septic tanks or biogas digesters with relatively simple types of waste, etc. Once the waste working conditions are complicated , the existing equipment can easily cause equipment blockage, resulting in failure to operate normally, and even equipment damag...
