Has the advantages of short flow and high integration degree of equipment.

The integrated earth pressure balance shield undisturbed muck recycling treatment production line is applicable to recycling treatment of low-sand-content subway shield muck, and can be applied to treatment of other muck.

Please refer to fig. 2 with focus, the grain extrusion refinement apparatus 006 includes two upper press rolls 0200 and a lower press roll 0500 disposed below the two upper press rolls 0200, and the grain extrusion refinement apparatus 006 further includes: the upper roller scraping plate 0800 arranged below each upper pressing roller 0200, the lower roller scraping plate 0700 arranged below each lower pressing roller 0500, the upper roller cleaning air-water injector 0400 arranged right opposite to the upper roller scraping plate 0800, the lower roller cleaning air-water injector 0600 arranged right opposite to the lower roller scraping plate 0700, and the particle extrusion refining equipment 006 further comprises: a gas-water source providing assembly for simultaneously supplying pressurized gas and water source to the upper roll cleaning gas-water injector 0400 and the lower roll cleaning gas-water injector 0600.

That is, in the above embodiment, the upper roll cleaning air water jet 0400 is provided at a position near the bottom of the upper press roll 0200, and the lower roll cleaning air water jet 0600 is provided at a position near the bottom of the lower press roll 0500. The upper press roller 0200 and the lower press roller 0500 are located in the chamber of the particle extrusion refinement apparatus 006.

During operation, materials (slag soil excavated by the shield) enter from the feed inlet 0300 and flow out from the lower discharge outlet after passing through the two upper press rolls 0200 and the two lower press rolls 0500. The two upper press rolls 0200 are matched to realize primary crushing of the dregs, and the two lower press rolls 0500 are matched to realize secondary crushing of the dregs.

When the material passes through the extrusion surface, the adhesion of the cohesive slag is strong, the cohesive slag can be immediately adhered to the roller wall of the compression roller, and the cohesive material can be primarily cleaned by the upper roller scraping plate 0800 and the lower roller scraping plate 0700 along with the rotation of the roller surface, and a certain gap is reserved because the scraping plate is not completely adhered to the roller wall. Therefore, the surface layer of the double-roller residual soil layer after passing through the scraping plate, the upper roller cleaning air-water injector 0400 and the lower roller cleaning air-water injector 0600 can impact and clean the residual soil layer under the impact force of the air-water mixed flow, and through the process, the slag adhering to the roller wall is greatly reduced, so that the soil thrown out by the roller surface and adhered to the wall surface is correspondingly reduced, and the cleaning air-water injector arranged on the upper part of the wall surface can regularly wash the wall surface, so that a large amount of viscous slag cannot be remained on the wall surface.

Therefore, the granule extrusion refining equipment 006 of the invention can timely remove the dregs stuck on the press roller through the combined action of the scraping plate and the air water ejector. The particle extrusion refining equipment 006 is guaranteed to be continuously used, the equipment is not required to be shut down and cleaned manually, the difficulty and the maintenance cost of equipment maintenance are reduced, the cleaned muddy water is immediately mixed with other materials and enters the next process, and the on-site cleaning can be effectively guaranteed.

According to an embodiment of the present invention, the air-water source providing assembly includes an air compressor 01000, a gas tank 01100 coupled to the air compressor 01000, the gas tank 01100 coupled to the upper roll cleaning air water injector 0400 and the lower roll cleaning air water injector 0600, respectively, and a water tank 0900 coupled to the upper roll cleaning air water injector 0400 and the lower roll cleaning air water injector 0600, respectively, via a water outlet pipe 01200.

In this embodiment, the air compressor is used to supply pressurized air, the air tank 01100 is used to store pressurized air, and the water tank 0900 is used to supply water. In specific implementation, high-pressure gas is used as power, a small amount of water is combined to form a pulsation flushing force, the roller wall of the compression roller and the chamber of the particle extrusion refining equipment 006 are cleaned, the cohesive coating of the slag on the roller surface can be timely removed, and the problem caused by cohesive coating of the slag in the cohesive shield slag crushing refining process is solved. Meanwhile, slag soil is prevented from adhering to the roller surface and the side wall of the particle extrusion refining equipment 006, and continuous and stable operation of the equipment is ensured. The particle extrusion refining equipment 006 can solve the technical problem that the adhesion of the viscous slag soil material is difficult to clean, and automatically clean the roller wall and the chamber under the condition of using a small amount of water. Namely, the particle extrusion refining equipment 006 has the advantages of low system energy consumption and small cleaning water consumption by adopting a mode of combining pressure gas and a small amount of water.

According to an embodiment of the present invention, a flow control valve 01300 is provided on the outlet pipe 01200. In this embodiment, the size and the switch of the water inlet of the water tank 0900 can be adjusted by the flow adjusting valve 01300, so as to meet different water flow demands.

According to an embodiment of the present invention, the upper roll cleaning air water injector 0400 and the lower roll cleaning air water injector 0600 have the same structure. In this embodiment, the structure is advantageous for molding, and the degree of standardization of the equipment parts is improved.

Since the upper roll cleaning air water jet 0400 and the lower roll cleaning air water jet 0600 have the same structure, the structure of the upper roll cleaning air water jet 0400 will be specifically described below by taking the structure of the upper roll cleaning air water jet 0400 as an example.
