Description

Technical Field

[0001] The utility model relates to the technical field of slag processing, in particular to a construction slag processing device. Background Art

[0002] Shield construction is a fully mechanized construction method in underground excavation. It involves pushing a shield machine underground, supporting the surrounding rock with the shield shell and segments to prevent collapse into the tunnel. At the same time, a cutting device is used to excavate the soil in front of the excavation face, and the soil is transported out of the tunnel by excavation machinery. The treatment of the transported soil is usually an indispensable part of the construction process.

[0003] At present, the method of handling the transported slag is relatively simple. Generally, the transported slag is reused and transported to places where soil is needed to be filled as filling soil. Since the soil discharged by shield construction contains a lot of water, the most common treatment method is to pile it up in a designated area and let it dry naturally for standby use, which takes a long time. Utility Model Content

[0004] The present disclosure relates to a construction waste soil processing device, which solves the problem that the current treatment method for transported waste soil is relatively simple. The most commonly used treatment method is to pile up the waste soil containing a large amount of water in a designated area and wait for it to dry naturally for use, which takes a long time.

[0005] In a first aspect of the present disclosure, a construction waste processing device is provided, which specifically includes: a dewatering pipe body, a motor, a spiral conveying rod, a filter plate, an outer shell, an extrusion block, a nut and a cutter ring; the motor is fixedly installed on the rear end of the dewatering pipe body, and the spiral conveying rod is installed inside the dewatering pipe body; the filter plate is installed on the inside of the dewatering pipe body, and the outer shell is fixedly installed on the outside of the dewatering pipe body; the front end of the spiral conveying rod is connected to the extrusion block, and the extrusion block is located outside the front end of the dewatering pipe body; the front end of the spiral conveying rod is provided with an external thread, and the front end of the spiral conveying rod is threadedly connected to the nut; the cutter ring is fixedly installed on the outside of the extrusion block.

[0006] Furthermore, a soil feeding funnel is provided at the rear end of the top of the dehydration pipe body, a soil discharge port is provided at the front end of the dehydration pipe body, a spiral conveying rod rotates in the dehydration pipe body, and a driving shaft of the motor is connected to the spiral conveying rod.

[0007] Furthermore, the outside of the dehydration tube body is provided with a dehydration hole in a circumferential shape, the filter plate is located inside the dehydration hole, the inner side of the filter plate is flush with the inner side of the dehydration tube body, and the spiral conveying rod is in contact with the inner side of the filter plate.

[0008] Furthermore, the front end of the spiral conveying rod slides through the extrusion block, the extrusion block contacts the soil discharge port, two guide grooves are provided at the front end of the spiral conveying rod, and two guide blocks are provided inside the extrusion block. The guide blocks are slidably connected in the guide grooves, and the guide blocks and the guide grooves slide in cooperation to guide the movement of the extrusion block.

[0009] Furthermore, a spring is mounted on the outside of the front end of the spiral conveying rod, the front end of the spring contacts the nut, and the rear end of the spring contacts the extrusion block. The spring applies a backward thrust to the guide block, so that the guide block is in close contact with the discharge port.

[0010] Furthermore, the interior of the outer shell is connected with the dehydration drainage hole, and a drainage pipe is provided at the bottom of the outer shell, which is connected with the filter press. When the slag is poured into the dehydration pipe body through the soil inlet funnel, the motor drives the spiral conveying rod to rotate, and the spiral conveying rod drives the extrusion block to rotate synchronously. The spiral conveying rod transports the slag to the front end, and the slag is gradually compressed, so that the moisture contained in the slag is affected by the extrusion and flows into the outer shell through the filter plate. When the slag reaches the discharge port, the water content inside the slag is reduced, and the solidified slag pushes open the extrusion block, and the slag is discharged through the discharge port, which can effectively reduce the water content of the slag and make the water content of the slag meet the soil filling standard.

[0011] Furthermore, a crushing knife is arranged in a circular shape on the outside of the knife ring. The crushing knife is located at the soil discharge port, and the inner side of the crushing knife is in contact with the outer side of the dehydration pipe body. When the slag is squeezed out through the soil discharge port, the extrusion block drives the knife ring to rotate, and the slag is crushed by the crushing knife, so that the slag is in a refined and loose state.

[0012] The utility model provides a construction slag processing device, which has the following beneficial effects:

[0014] In addition, when the debris is squeezed out through the discharge port, the extrusion block drives the cutter ring to rotate, and the crushing knife crushes the debris, making the debris in a fine and loose state, which is convenient for transportation and stacking.
