Bidirectional filter pressing dehydrator

Abstract

The invention discloses a bidirectional filter pressing dehydrator comprising a rack and a vertical filter pressing system, wherein the rack is provided with a feeding bin, a dehydration cavity and a horizontal filter pressing system; the vertical filter pressing system comprises a vertical pressure head and a vertical hydraulic pressure driving device driving the vertical pressure head to vertically move, wherein the vertical pressure head is arranged on the vertical hydraulic pressure driving device; the vertical hydraulic pressure driving device is arranged on the upper part of the dehydration cavity, is controlled by a hydraulic pressure control system and drives the vertical pressure head to move up and down along the inner wall of the dehydration cavity. The invention ensures that rubbish is firstly dehydrated so as to cause water residual quantity in the rubbish to be greatly lowered, which is favourable for rubbish to stably combust, has simple structure and greatly improves dehydration efficiency.

Description

Technical field: [0001] The invention relates to a garbage treatment device, in particular to a domestic garbage dehydration device capable of horizontal and vertical pressure filtration. Background technique: [0002] In the prior art, during the collection and compression (transfer) vehicle transportation of urban residents' domestic garbage, sewage dripping is often caused due to problems such as sealing, which pollutes roads and damages the image of the city. The source of the dripping sewage is: 1. The original water of domestic garbage; 2. Since domestic garbage is collected every 24 hours, some substances with high water retention will undergo a fermentation process under the conditions of stack pressure and poor air permeability. The original high water retention material loses its water retention capacity and forms sewage. Existing transfer vehicles for garbage removal often only have simple garbage compression capabilities, and do not have the function of garbage ...

AI Technical Summary

Problems solved by technology

[0004] The domestic garbage dehydrator in the prior art only performs pressure filtration and dehydration on the garbage once, which cannot achieve the ideal dehydration rate

If these press-filtered garbage needs to be transferred, during the transfer process, the sewage seeping out of the garbage will cause secondary pollution to the surrounding environment; if it is incinerated, these garbage with high water content cannot be burned stably , the degree of complete combustion of garbage is not high
