Abstract

The invention discloses a vacuum-suction screw extrusion solid-liquid separation system including: a screw extrusion mechanism to which a continuously material-feeding mechanism and a continuously solid-discharging mechanism, a driving mechanism which provides rotation power to the screw extrusion mechanism, and a sealing box body which allows the screw extrusion mechanism to be sealed in and enables the continuously material-feeding mechanism and the continuously solid-discharging mechanism to be communicated with exterior. The system is characterized in that the screw extrusion mechanism is arranged obliquely with the height of an inlet height being lower than that of an outlet; a collecting tank is disposed on the bottom of the sealing box body, is communicated with the sealing box body and is used for collecting liquid, wherein the sealing box body is accommodated in a sealed water tank; the sealed water tank is also communicated with a vacuum machine which provides a vacuum suction force to the screw extrusion solid-liquid separation system; a water discharging outlet is disposed on the bottom of one end, which is closed to the continuously solid-discharging mechanism, of the collecting tank; and the water tank is provided with a continuously liquid-discharging mechanism. The system is high in reliability, is small in occupied area and can allow humidity of outlet materials to be controlled.

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. Background technique [0002] The existing method of treating sludge is mainly to filter and dedry it and then landfill it. 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 damage. Moreover, the existing equipment must also unde...
