Slurry treatment device based on multi-stage rotational flow system

Abstract

The invention discloses a slurry treatment device based on a multi-stage cyclone system. The device comprises a slurry pool, a centrifugal pump is arranged above the slurry pool, a water inlet of the centrifugal pump is fixedly connected with the interior of the slurry pool through a connecting pipe, a first-stage cyclone is arranged on the right side of the centrifugal pump, the water outlet of the centrifugal pump communicates with the slurry inlet of the first-stage cyclone through a connecting pipe, and a second-stage cyclone is arranged on the right side of the first-stage cyclone. The invention relates to the technical field of green geotechnical construction. According to the slurry treatment device based on the multi-stage rotational flow system, through the arrangement of a filter screen, a rotating plate, a cutting block, a first mounting plate, a second mounting plate and a hydraulic rod, before quick lime is added into a plate-and-frame filter press for water absorption, large lime particles in the quick lime are cut firstly, so that the large lime particles are cut into fine particles, the water is filtered by the filter screen and enters the plate-and-frame filter press for water absorption, the fine quicklime can improve the water absorption efficiency, and the practicability is very high.

Description

technical field [0001] The invention relates to the technical field of green rock and soil construction, in particular to a mud treatment device based on a multi-stage cyclone system. Background technique [0002] Mud is the product of construction operations such as bored piles, mud-water shields, and underground diaphragm walls. It has the characteristics of difficulty in utilization, high disposal costs, high pollution, and low utilization rate. According to statistics, the annual production of engineering mud in my country reaches 300 million cubic meters, and the treatment and comprehensive utilization of mud has become a key issue in engineering construction, urban environmental protection and resource recycling. [0003] At present, the treatment of waste mud mainly includes natural drying, chemical curing, and mechanical dehydration, and mechanical dehydration mostly uses plate and frame filter presses, belt filter presses, and decanter centrifuges. In the construct...
