Solid-liquid separator for environmental sanitation truck

Abstract

The invention discloses a solid-liquid separator for an environmental sanitation truck. The solid-liquid separator comprises a first-grade auger, a first-grade separation cylinder, a discharge device, a second-grade auger blade and a second-grade separation cylinder, wherein the first-grade separation cylinder is fixedly connected with a shell, is provided with a feed area, an exchange area and a recovery area in sequence, and coats the first-grade auger; the feed area is positioned at the front end of the first-grade separation cylinder, and is provided with a feed hole in the cylinder wall; the exchange area is positioned behind the feed area, and is provided with a grading hole in the cylinder wall; the recovery area is positioned behind the exchange area, and is provided with a recovery hole in the cylinder wall; the discharge device is positioned in an opening at the tail end of the first-grade separation cylinder for controlling the discharge of the first-grade separation cylinder; the cylinder wall of the second-grade separation cylinder is provided with a water filter hole, coats the exchange area and the recovery area of the first-grade separation cylinder,and is isolated from the feed area; and the inner wall of the second-grade separation cylinder and the outer wall of the first-grade separation cylinder are movably connected through a sealing bearing.

Description

technical field [0001] The invention relates to sanitation cleaning equipment, in particular to a solid-liquid separator for sanitation vehicles. Background technique [0002] The solid-liquid separator currently used is generally assembled by a moving dial, an auger and a clutch mechanism. The material moves axially under the pressure of the auger, and the moving dial overcomes the reaction force of the auger and moves a certain distance to mesh with the main shaft, and the auger drives the moving dial to rotate to complete the discharge action. This kind of solid-liquid separator is directly meshed with the main shaft due to the direct meshing transmission of the moving dial and the main shaft. Under the action of the high-speed rotation of the main shaft, it is easy to cause the discharge of the material to splash. Can not form a stable solid. Especially when the material contains gas, the separated material is still fluid, the separation effect is poor, the work effici...

AI Technical Summary

Problems solved by technology

Due to the direct meshing transmission between the moving dial and the main shaft, this kind of solid-liquid separator is easy to cause the discharge of the material to splash under the action of the high-speed rotation of the main shaft. does not form a stable solid

Especially when the material contains gas, the separated material is still fluid, the separation effect is poor, the work efficiency is low, and it is inconvenient
