Solid-liquid separating device with automatic blockage-clearing device

Abstract

The invention discloses a solid-liquid separating device for treating excrement wastewater. The solid-liquid separating device comprises a main box body (1), and a solid pushing mechanism (2) and a sand lifting mechanism (3) which are inclined relative to the main box body, wherein the solid pushing mechanism (2) is provided with a cylindrical porous filter cover (21), and the filter cover (21) is positioned inside the main box body (1); a plurality of holes are formed in all area of the filter cover (21) so as to enable water to enter the solid pushing mechanism; the solid pushing mechanism is provided with a first spiral blade (23), and the first spiral blade (23) is arranged inside the filter cover (21); the solid-liquid separating device is characterized by further comprising an automatic blockage-clearing mechanism (5); the automatic blockage-clearing mechanism (5) further comprises a rotating rod (51); a plurality of bulges (511) are regularly distributed on the rotating rod; and when the rotating rod is in a rotating state, the bulges (511) enter the meshes in the filter cover (21) in a matching manner so as to clear solid matters in the meshes. The solid-liquid separating device solves one of technical problems, namely how to improve the treatment efficiency of the conventional excrement wastewater treatment device; and the invention provides solid-liquid separating equipment achieving full filtering within the full height of a main machine body.

Description

technical field [0001] The invention relates to the field of water treatment equipment, in particular to a solid-liquid separation device for treating fecal wastewater. Background technique [0002] The solid-liquid separation device (device) is a device that filters and separates the solid matter in the water fluid, transfers it, and presses and dehydrates it. It is an indispensable equipment in manure treatment. The solid-liquid separation device used in the manure treatment industry is usually transformed from the solid-liquid separation device in the sewage treatment industry. [0003] Existing solid-liquid separation devices for feces treatment are usually semi-filtered, that is, the sewage maintains a suitable water level in the tank, and does not exceed this water level, and the filter device can filter and remove garbage in the waste water; when the water level exceeds this level, the excess part Then overflow the filter device, the fecal dirt in the water cannot b...

AI Technical Summary

Problems solved by technology

[0005] During use, the applicant found that when the solid-liquid separation device is used to treat fecal sewage, the soft feces are likely to block the mesh of the filter cover under the operation of the solid pushing mechanism. Therefore, it is necessary to stop and clean it every time it runs Mesh, requires additional labor
