Slag stone quick cleaning device for slurry shield machine

Abstract

The invention relates to the mechanical field related to shield machine construction, in particular to aslag stone quick cleaning device for a slurry shield machine. Through a stone collecting box installed under a slurry discharging pipeline of a slurry circulating flow system of the shield machine, the stone collecting box is of a battery body structure, two ends of the stone collecting box are provided with an end cover and a manhole cover, the end cover is collected with pipe bending cylinder rod head, and a stone pushing plate through a collection rod, the stone pushing plate is driven to move through apipe bending cylinder, and slag stones are pushed out, the end, away from the ground and close to the ground, of the stone collecting box are correspondingly provided with ball valves, the end, close to the ground, of the ball valve is connected with a pneumatic diaphragm pump, before pushing stones, slurry is pumped out through the pneumatic diaphragm pump, and a plurality of the slurry in the slag stones pushed out by the stone pushing plate is avoided. According to the slag stone quick cleaning device, automatic material unloading of the stone collecting box is obtained, and problems ofslag stone cleaning difficulty, high labor intensity of workers and low cleaning efficiency in the need for manual cleaning the stone collecting box are avoided.

Description

technical field [0001] The invention relates to the mechanical field related to shield tunneling machine construction, in particular to a quick cleaning device for slag and rocks for muddy water shield machines. Background technique [0002] The mud circulation system of the slurry shield machine is the core system of slag transportation. Its mud circulation system pumps the bentonite mud from the mud water treatment station into the face through the slurry inlet pump. There is a certain working pressure on the face, so that the bentonite mud is embedded In the gaps between soil particles, a layer of "mud film" is formed to stabilize the soil layer and improve water permeability. The slag cut by the cutter head is mixed with the mud in the excavation chamber, discharged through the slurry discharge pipe, and sent to the mud water treatment station to separate the slag from the mud and realize the recycling of the mud. However, during the continuous excavation process of the...
