Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] Example 1: Reference Figures 1-3 This embodiment provides a waste soil treatment device, including... A conveying assembly is included, with one end located within the storage tank 1. The conveying assembly comprises an inclined conveying cylinder 401, one end of which is located within the storage tank 1. A conveying shaft 402 is rotatably connected within the conveying cylinder 401, and spiral conveying blades 403 are fixedly connected to the periphery of the conveying shaft 402. A conveying motor 404, which drives the conveying shaft 402 to rotate, is fixedly connected to the conveying cylinder 401. A connecting cylinder 405 is connected to the periphery of the end of the conveying cylinder 401 furthest from the storage tank 1. The connecting cylinder 405 is located within the separation box 2 and communicates with the screening assembly. The conveying motor 404 drives the conveying shaft 402 to rotate, which in turn drives the spiral conveying blades 403 to rotate, thereby conveying the slag and soil within the storage tank 1 to the screening assembly.

[0020] Separation box 2, with a support frame 3 fixedly connected to the bottom of separation box 2, separation box 2 is set at an angle, and the end of the conveying component away from storage pool 1 is connected to the higher end of separation box 2; A screening component is used to screen large stones in the slag. The screening component is located inside the separation box 2, and the conveying component is connected to the screening component. The screening component includes a screening cylinder 5 rotatably installed inside the separation box 2. The end of the connecting cylinder 405 is located inside the screening cylinder 5 and rotatably cooperates with the screening cylinder 5. Several screen holes are opened on the periphery of the screening cylinder 5. There is a gap between the outer wall of the screening cylinder 5 and the inner wall of the separation box 2. An installation ring 6 and a discharge cylinder 7 are fixedly connected inside the separation box 2. The top end of the screening cylinder 5 is rotatably installed inside the installation ring 6, and the bottom end of the screening cylinder 5 is located inside the discharge cylinder 7 and rotatably connected to the inner wall of the discharge cylinder 7. A rotating component for controlling the rotation of the screening cylinder 5 is installed inside the separation box 2.

[0021] The sealing assembly is located inside the separation chamber 2 and at the bottom of the screening assembly. The sealing assembly includes two semi-circular plates 901 located inside the discharge cylinder 7 and rotatably connected to the inner wall of the discharge cylinder 7. The two semi-circular plates 901 are symmetrically arranged and correspond to the bottom end of the screening cylinder 5. An arc-shaped strip 902 is fixedly connected to the side wall of the semi-circular plate 901 away from the screening cylinder 5. An arc-shaped groove 903 is opened on the side wall of the discharge cylinder 7 corresponding to the arc-shaped strip 902. One end of the arc-shaped strip 902 slides in the arc-shaped groove 903. A compression spring 904 is fixedly connected between the end of the arc-shaped strip 902 in the arc-shaped groove 903 and the bottom wall of the arc-shaped groove 903. A limiting assembly for limiting the semi-circular plates 901 is installed inside the discharge cylinder 7. The semicircular plate 901 is limited by the limiting component to ensure that it is closed during the screening process, so as not to affect the screening effect. After the screening is completed, the semicircular plate 901 is opened to allow the large stones remaining in the screening cylinder 5 to be transported out from the discharge cylinder 7.

[0022] The crushing assembly is positioned opposite the end of the separation chamber 2 furthest from the conveying assembly. The crushing assembly includes a crushing box 15, which is positioned opposite the discharge cylinder 7. Two opposing crushing rollers 16 are rotatably mounted inside the crushing box 15. A crushing motor that drives the two crushing rollers 16 is mounted on the outer wall of the crushing box 15. A discharge port is located at the bottom of the crushing box 15, and a guide plate 17 is installed at the discharge port. The end of the guide plate 17 furthest from the discharge port is positioned opposite the conveyor belt 14. The crushing motor drives the crushing rollers 16 to rotate, crushing large pieces of stone, which are then conveyed onto the conveyor belt 14 via the guide plate 17.

[0023] Furthermore, the conveyor belt 14 is a conventional conveyor belt 14 in this field, and its conveyor motor, support, conveyor rollers and other related equipment are all existing equipment. This is a conventional application of the conveyor belt 14, and will not be described in detail here.

[0024] A further optimized design includes a rotating assembly comprising a gear ring 801 fixedly connected to the outer wall of the screening cylinder 5 at its top, a rotating motor 802 fixedly connected to the outer wall of the separation chamber 2, and a rotating gear 803 fixedly connected to the output shaft of the rotating motor 802. The rotating gear 803 is located inside the separation chamber 2 and meshes with the gear ring 801. The rotating motor 802 drives the rotating gear 803 to rotate, which in turn drives the screening cylinder 5 to rotate via the gear ring 801, thereby centrifugally separating the slag and soil raw materials inside the screening cylinder 5, thus completing the screening process.

[0025] In a further optimized design, the limiting component includes a moving ring 1001 located inside the discharge cylinder 7 and slidably connected to the inner wall of the discharge cylinder 7. A limiting rod 1002 is fixedly connected to the moving ring 1001 in correspondence with the arc-shaped strip 902. A limiting hole adapted to the limiting rod 1002 is opened on the arc-shaped strip 902. The limiting rod 1002 passes through the limiting hole. Several push rods 1003 are fixedly connected to the periphery of the moving ring 1001. Several sliding grooves 1004 are opened on the side wall of the discharge cylinder 7 in correspondence with the push rods 1003. The push rods 1003 slide within the sliding grooves 1004. The push rods 1003 pass through the sliding grooves 1004 and the top of the push rods 1003 is located in the gap between the screening cylinder 5 and the separation box 2. A pressure spring 1005 is fixedly connected between the bottom wall of the sliding groove 1004 and the push rods 1003. The moving ring 1001 drives the limiting rod 1002 to separate from the limiting hole, so that it no longer limits the semi-circular plate 901, thereby allowing the semi-circular plate 901 to fall under the gravity of the large stone. This allows it to fall into the crushing assembly for crushing after screening.

[0026] In a further optimized design, a cleaning ring 11 is slidably fitted onto the outer side of the screening cylinder 5. The outer wall of the cleaning ring 11 is slidably connected to the inner wall of the separation chamber 2. A telescopic electric cylinder 12 is fixedly connected inside the separation chamber 2. The movable end of the telescopic electric cylinder 12 passes through the mounting ring 6 and is fixedly connected to the end face of the cleaning ring 11. Furthermore, the telescopic electric cylinder 12 is a multi-stage electric cylinder. By driving the cleaning ring 11 to move, it can clean and push the fine material on the inner wall of the separation chamber 2, causing it to move through the fine material inlet 13 onto the conveyor belt 14. At the same time, when the cleaning ring 11 moves to the push rod 1003, it squeezes the push rod 1003 to move, thereby pushing the moving ring 1001 to move.

[0027] Furthermore, an arc-shaped plate is fixedly connected to the bottom of the discharge cylinder 7 to guide the flow and move large stones between the two crushing rollers 16.

[0028] Furthermore, a vertical plate is fixedly connected to the bottom surface of the separation box 2. The vertical plate is located on the side of the conveyor belt 14 and can block the falling slag and prevent it from falling to the outside of the conveyor belt 14.

[0029] The design is further optimized by providing a fine material inlet 13 on the bottom side wall of the separation chamber 2. A conveyor belt 14 is installed below the separation chamber 2, positioned below the fine material inlet 13. This allows the fine material passing through the screening cylinder 5 to fall onto the conveyor belt 14 directly for collection via the fine material inlet 13.

[0030] The working process of this embodiment: In use, the conveyor motor 404 is started, which drives the conveyor shaft 402 and the spiral conveyor blades 403 to rotate and transport the slag in the storage tank 1. The slag is then transported through the conveyor cylinder 401 to the connecting cylinder 405 and into the screening cylinder 5. Then, the rotary motor 802 is started, which drives the rotary gear 803 to rotate. This, in turn, drives the screening cylinder 5 to rotate through the gear ring 801, thereby centrifugally screening the slag in the screening cylinder 5. During the screening process, soil particles and small-diameter sand and gravel move through the screen holes to the gap between the separation box 2 and the screening cylinder 5, and then move through the fine material inlet 13 to the conveyor belt 14 for transport. Large stones remain inside the screening cylinder 5. After the screening is completed, the telescopic electric cylinder 12 is activated, which pushes the cleaning ring 11 to move. During the movement of the cleaning ring 11, it can clean and push the fine material remaining on the inner wall of the separation box 2, so that it falls onto the conveyor belt 14 through the fine material inlet 13. When the cleaning ring 11 moves to the push rod 1003, it pushes the push rod 1003 to move. The push rod 1003 drives the moving ring 1001 to slide, so that the limit rod 1002 separates from the arc strip 902. At this time, the semi-circular plate 901 can open under the gravity of the large stones. The large stones move through the discharge cylinder 7 into the crushing box 15, and are crushed under the action of the crushing roller 16 and then conveyed to the conveyor belt 14.

[0031] Example 2: Reference Figure 4 This embodiment provides a slag treatment device. The only difference between this embodiment and Embodiment 1 is that an installation frame 18 is provided inside the separation box 2. One end of the installation frame 18 is detachably connected to the connecting cylinder 405, and the other end of the installation frame 18 is detachably connected to the discharge cylinder 7. The middle of the installation frame 18 is a fixed shaft coaxially arranged with the screening cylinder 5. Two semi-circular plates 901 are respectively provided with semi-circular holes adapted to the fixed shaft at opposite positions. Several fixed blades 19 are fixedly connected to the periphery of the fixed shaft. By coaxially arranging the fixed shaft inside the screening cylinder 5 and installing the fixed blades 19, the slag inside the screening cylinder 5 continuously collides with the fixed blades 19 during rotation, accelerating the movement of the slag inside and speeding up the screening process.

[0032] Example 3: Reference Figures 5-6This embodiment provides a slag treatment device. The only difference between this embodiment and Embodiment 1 is that a striking motor 20 is fixedly connected to the bottom end of the discharge cylinder 7, and a rotating plate 21 is fixedly connected to the output shaft of the striking motor 20. A baffle 22 is fixedly connected to the bottom end of the separation box 2. The rotating plate 21 is located between the baffle 22 and the crushing box 15. Several receiving slots are opened inside the rotating plate 21, and moving plates are slidably connected in the receiving slots. Several striking plates 23 are arranged around the rotating plate 21 corresponding to the receiving slots. A connecting column is fixedly connected to the side of the extrusion plate. The connecting column passes through the side wall of the rotating plate 21 and is fixedly connected to the receiving slot and the moving plate. A return spring 24 is fixedly connected between the side of the moving plate away from the connecting column and the side wall of the receiving slot. The striking motor 20 drives the rotating plate 21 to rotate, thereby driving the striking plates 23 to move. During the movement of the striking plates 23, they continuously collide with the baffle 22 and the crushing box 15, thereby facilitating the movement of the slag and making it easier to transport.
