Description

Technical Field

[0001] The invention relates to the technical field of slag processing equipment, in particular to an environmentally friendly shield slag processing device. Background Art

[0002] With the development of social economy, more and more railways, highways, subways and other roads and tracks are being built in full swing. As the tunnel construction process proceeds, a large amount of shield slag will be generated. Due to the needs of shield construction technology and the geological characteristics of the excavation stratum, the shield slag contains a large amount of water, and the shield slag becomes thin mud or mud, which is not easy to transport and transfer. The presence of sand and gravel in the shield slag affects the dehydration effect of the shield slag, and useful components such as sand and gravel are not easy to recycle. In addition, the shield slag pile with high water content has landslide and safety hazards.

[0003] Prior art publication number CN210410300U discloses a shield slag processing device, comprising a hollow shell, wherein the shell has a first chamber, a second chamber and a third chamber, the bottom of the first chamber is connected to the bottom of the second chamber, the second chamber and the third chamber are separated by a first partition, and a stirring and transporting wheel is provided in the second chamber; the stirring and transporting wheel has a wheel body and a plurality of wheel buckets fixed on the wheel body, and the plurality of wheel buckets are evenly distributed along the outer edge of the wheel body.

[0004] In the above device, the slag slurry is thrown onto the screening mechanism of the third chamber by the wheel bucket arranged in the second chamber. The screening mechanism is two parallel screens. The screens of this structure will cause sand particles to directly block the screen holes, and they need to be cleaned all the time to ensure that the screen holes are unobstructed. In addition, it is difficult to ensure uniform mixing of the mud by stirring the mud with the wheel bucket. It is difficult to separate sand particles of different particle sizes from the unevenly mixed mud, and it is difficult to recycle the sand particles in the slag. Summary of the invention

[0008] A plurality of first agitators are arranged in the third cavity, and a plurality of second agitators are arranged in the screen drum. The third cavity stirs the water-containing slag in the mixing cavity through the plurality of the first agitators therein and stirs the slag into a slurry state. The screen drum is used to filter the slag slurry and let the fine sand particles and water fall into the second cavity. The first cavity is used to receive and store the coarse sand particles obtained after screening by the screen drum.

[0009] As a further solution of the present invention: a hollow tube is rotatably connected to the middle position inside the third cavity, one end of the hollow tube is connected and fixed to the sieve drum, and the other end thereof is rotatably connected to penetrate the inner wall of the tank body and extends to the outside of the tank body, a connecting rod is rotatably connected in the hollow tube, both ends of the connecting rod are rotatably penetrate the hollow tube, one end of the connecting rod is rotatably penetrate the inner wall of one side of the sieve drum and is rotatably connected to the inner wall of the other side of the sieve drum, the hollow tube and the connecting rod are both transmission-connected to an external driving mechanism, a plurality of the first agitators are respectively fixed on the hollow tube at equal intervals, and a plurality of the second agitators are respectively fixed on the connecting rod at equal intervals.

[0010] As a further solution of the present invention: the two ends of the sieve drum are rotatably connected to the first partition plate and the second partition plate through bearings respectively, sealing rings are arranged between the first partition plate, the second partition plate and the sieve drum and between the first partition plate and the inner wall of the tank body, a plurality of sieve holes are evenly arranged on the surface of the middle part of the sieve drum body, a plurality of material guide ports are evenly arranged on the inner walls at both ends of the sieve drum body, and solenoid valves are installed in the plurality of material guide ports.

[0011] As a further solution of the present invention: support rings are provided on both sides of the bottom of the tank body, and the support rings are semicircular structures, and their shape is adapted to the outer shape of the tank body. Bottom plates are provided under the two support rings, and multiple telescopic rods are provided between the two bottom plates and the support rings on the corresponding side, the bottom ends of the telescopic rods are fixed to the bottom plates, and the top ends of the telescopic rods are rotatably connected to the support rings on the corresponding side through joints, and locking structures are provided on the multiple telescopic rods.

[0012] As a further solution of the present invention: an oil cylinder is installed in the middle position above the bottom plate on one side of the third cavity among the two bottom plates, and the output end of the oil cylinder extends upward to one side of the support ring and is rotatably connected to the support ring through the joint.

[0013] As a further solution of the present invention: a feed hopper is fixed on one side of the top of the tank body corresponding to the third cavity, a discharge pipe is fixed on one side of the bottom of the tank body corresponding to the second cavity, an opening is provided on the inner wall of one end of the tank body corresponding to the first cavity, and a sealing cover is provided in the opening.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In the present invention, the hollow tube and the connecting rod can be rotated respectively by an external driving mechanism. The third cavity can stir the water-containing slag in the mixing chamber and stir the slag into a slurry state through the cooperation of the hollow tube inside the third cavity and the first agitator. The slag in the slurry state is more convenient for separating sand particles of different particle sizes therein. The slag slurry enters the screen drum through the guide port for screening. Further, the screen drum is fixedly connected to the hollow tube. When the hollow tube rotates, the screen drum will be driven to rotate synchronously. In addition, the connecting rod in the screen drum will also rotate. The rotation direction of the connecting rod can be the same as or opposite to the rotation direction of the screen drum. Through the self-rotation of the screen drum and the self-rotation of the connecting rod and the second agitator in the screen drum, the slurry in the screen drum is stirred at the same time, so that the slurry is quickly separated. The fine sand particles and water in the slurry fall into the second cavity through the sieve holes and are directly discharged from the discharge pipe. The coarse sand particles in the slurry flow into the first cavity through the guide port. The coarse sand particles can be taken out by opening the sealing cover. The coarse and fine sand particles are separated, which is convenient for recycling these resources.

[0017] 2. In the present invention, one end of the tank body can be lifted upward by the oil cylinder to tilt the tank body to one side. When the oil cylinder lifts the tank body, the provided joint can prevent the telescopic rod from interfering with the movement of the tank body, thereby ensuring that one end of the tank body can move up and down freely. Furthermore, after the tank body is tilted, the mud in the third cavity can flow into the screen drum more smoothly, and the coarse sand particles in the screen drum can also flow into the first cavity more smoothly. In addition, in actual use, the tank body can be repeatedly lifted by the oil cylinder to make one end of the tank body reciprocate up and down, thereby vibrating the mud inside the tank body, mixing the mud evenly, avoiding mud hanging on the wall, and making screening easier, thereby shaking off some sand particles stuck in the screen holes, ensuring that the screen holes are unobstructed, and the slag treatment effect is better.
