Description

Technical Field

[0001] The utility model belongs to the technical field of the mud treatment device for a slurry shield machine, and particularly relates to a mud treatment device for a slurry shield mechanism. Background Technique

[0002] The slurry shield is a pressure balance shield that uses slurry as the main medium to balance the formation pressure of the tunnel excavation face and discharges the slag through the slurry conveying system. The soil slag excavated by the shield is mixed with the slurry in the slurry chamber and then discharged by the sludge pump in the form of slurry from the discharge pipe, and is transported to the ground. Then, it is separated by a screening machine. The separated slurry is re-adjusted and then transported to the excavation face through the slurry supply pipe. However, the defect in the prior art is that there is no better slurry screening and better recycling and treatment functions for the slurry.

[0003] The existing Chinese patent application number CN221319736U discloses a drilling mud treatment device for recycling sewage, including a housing of the drilling mud treatment device. The top right side of the housing of the drilling mud treatment device is provided with a feed inlet, and the lower left side of the housing of the drilling mud treatment device is provided with a discharge pipe. A mud removal device is arranged at the lower right side inside the housing of the drilling mud treatment device, and an auxiliary device is arranged in the middle on the left side inside the housing of the drilling mud treatment device. Through the cooperation among the second electric push rod, the square plate, the support plate, the baffle plate and the inclined plate, the baffle plate protrudes from the inclined plate. Since the weight of the sludge is greater than that of the oil-water mixture, when the drilling mud flows slowly, the sludge is located below, and the baffle plate will block the sludge in the drilling mud, while the oil-water mixture will flow to the left, realizing the separation of the sludge, and all the sewage can be recycled, making the separation of the sewage more thorough. However, it does not propose a mud treatment device for a slurry shield mechanism.

[0004] For another example, Chinese Patent Application No. CN211008646U discloses a slurry circulation slag discharge system for a shaft tunneling machine, which includes a slurry inlet pipeline, a slurry discharge pipeline, a flushing pipeline, a bypass pipeline and a slurry treatment device. One end of the slurry inlet pipeline is connected to the slurry treatment device, and the other end is arranged in the excavation chamber of the tunneling machine to realize the transportation of the slurry treated by the slurry treatment device into the excavation chamber. One end of the slurry discharge pipeline is arranged in the excavation chamber, and the other end is connected to the slurry treatment device to transport the slurry in the excavation chamber to the slurry treatment device through the slurry discharge pipeline; the flushing pipeline is connected to the slurry discharge port of the slurry inlet pipeline and the slurry discharge pipeline located in the excavation chamber to dredge the slurry discharge port through the flushing pipeline. The bypass pipeline is connected to the slurry inlet pipeline and the slurry discharge pipeline to form a slurry transportation cycle among the slurry inlet pipeline, the bypass pipeline, the slurry discharge pipeline and the slurry treatment device. The slurry circulation slag discharge system of this utility model integrates functions of circulating slag discharge and dredging of the slurry discharge port, and the bypass pipeline is set to facilitate the maintenance of the system. However, it also does not propose a slurry treatment device for a slurry balance shield mechanism. Summary of the Utility Model
