Push type slurry dewatering processing equipment and processing method

Abstract

The invention provides push type slurry dewatering processing equipment and a processing method. According to the technical scheme, waste slurry can be directly pushed by a piston and changed into a condensed slurry from a dilute slurry under the premise of no flocculating agent, and the condensed slurry is changed into a solid slurry through a high-pressure environment. The dewatering equipment and the processing method are capable of preventing environment from being polluted, possess good dewatering performance and cater to market demands.

Description

technical field [0001] The invention belongs to the technical field of mud treatment equipment, and mainly relates to a pushing type mud dehydration treatment equipment and a treatment method. Background technique [0002] At present, with the development of urban construction, the construction of bored piles and underground diaphragm walls is a major part of urban construction, and these construction methods require a large amount of mud, and a large amount of waste mud will be generated as the construction progresses. These muds are as follows: Without treatment, its water content is as high as 96%, and its volume is very large, and any discharge will cause certain pollution to the environment. Therefore, various mud dehydration machines are now used in construction to dehydrate the waste mud into mud cakes. Shipped off site. [0003] However, in the use of mud dewatering mechanical devices currently on the market, since mud water is a suspension liquid containing a certa...

Problems solved by technology

[0003] However, in the use of mud dewatering mechanical devices currently on the market, since mud water is a suspension liquid containing a certain amount of fine mud particles in the water, in the mud dehydration process, in order to facilitate solid-liquid separation, a certain amount must be added to the mud water. Amount of flocculant

The unique function of polymer flocculants is used to destroy the stability of mud water, so that the mud particles can quickly aggregate and settle from the water, thereby improving the separation effect of mud water, but the cost of using flocculants is quite high and it also pollutes the environment to a certain extent.
