[0002] A spiral sludge dewatering machine is a device for treating sludge. Through the operation of a double spiral shaft, by means of mechanical pressing, the water content in the sludge is greatly reduced, thereby realizing the dewatering treatment of the sludge. This device is usually used in sewage treatment plants, industrial wastewater treatment, and other occasions that require the treatment of a large amount of sludge.

[0003] However, the traditional spiral sludge dewatering machine is fixedly installed with a spray head at the top of the dewatering end to clean the sludge dewatering machine, prevent sludge from accumulating and caking inside the device, and maintain the normal operation efficiency and stability of the device. It is difficult to clean the side of the dewatering machine, resulting in poor cleaning effect. In view of the above problems, the inventor proposes a novel spiral sludge dewatering machine to solve the above problems. Summary of the Utility Model

[0004] In order to solve the problem that the cleaning mechanism of the traditional spiral sludge dewatering machine is not comprehensive; the purpose of the utility model is to provide a novel spiral sludge dewatering machine.

[0005] To solve the above technical problems, the utility model adopts the following technical scheme: A novel spiral sludge dewatering machine, including a mounting frame, inside which a dewatering machine body is fixedly installed. One side of the mounting frame is fixedly connected with a fixed rod, and the far side of the fixed rod away from the mounting frame is rotatably connected with a first rotating rod. The outer side of the fixed rod near the first rotating rod is rotatably connected with a second rotating rod. The far ends of the first rotating rod and the second rotating rod away from each other are fixedly connected with limit rods. An arc-shaped groove is opened on the side of the mounting frame near the limit rods, and the limit rods are slidably clamped in the arc-shaped groove. The far ends of the limit rods away from the second rotating rod are fixedly connected with water delivery pipes, which are located on both sides of the dewatering machine body. On the opposite sides of the water delivery pipes, equally spaced spray heads are fixedly installed. One side at the top of the water delivery pipes is fixedly connected with connecting hoses. The bottom end of the mounting frame is fixedly connected with a bottom plate. One side at the bottom of the mounting frame is fixedly connected with a drain pipe, which is communicated with the inside of the mounting frame, and a switching valve is installed on the drain pipe.

[0006] Preferably, a mounting plate is fixedly connected to the bottom end of the side of the mounting frame near the limit rod. The top end of the mounting plate is rotatably connected with a threaded rod, and a moving block is threadedly connected to the outer side of the threaded rod. Both sides of the moving block are rotatably connected with connecting rods, and the far ends of the connecting rods away from the moving block are rotatably connected with the second rotating rod. A stepping motor is fixedly installed at the bottom end of the mounting plate, and the driving end of the stepping motor is fixedly connected with the threaded rod.

[0007] Preferably, a guide rod is fixedly connected to one side of the top of the mounting plate close to the threaded rod, and the moving block is slidably clamped outside the guide rod.

[0017] Embodiment: As Figures 1-3 shown, the present utility model provides a new type of spiral sludge dewatering machine, including a mounting frame 1. Inside the mounting frame 1, a dewatering machine body 2 is fixedly installed. One side of the mounting frame 1 is fixedly connected with a fixed rod 3. The central axis of the dewatering machine body 2 is on the same straight line as the central axis of the dewatering machine body 2. One side of the fixed rod 3 away from the mounting frame 1 is rotatably connected with a first rotating rod 4. One side of the outer side of the fixed rod 3 close to the first rotating rod 4 is rotatably connected with a second rotating rod 5. The ends of the first rotating rod 4 and the second rotating rod 5 away from each other are both fixedly connected with a limiting rod 6. An arc-shaped groove 7 is opened on one side of the mounting frame 1 close to the limiting rod 6. The limiting rod 6 is slidably clamped in the arc-shaped groove 7. The ends of the limiting rod 6 away from the second rotating rod 5 are both fixedly connected with a water delivery pipe 8. The water delivery pipes 8 are located on both sides of the dewatering machine body 2. On the opposite sides of the water delivery pipes 8, a plurality of spray heads 9 are fixedly installed at equal intervals. One side of the top end of the water delivery pipe 8 is fixedly connected with a connecting hose 16.

[0018] At the bottom end of one side of the mounting frame 1 close to the limiting rod 6, a mounting plate 10 is fixedly connected. The top end of the mounting plate 10 is rotatably connected with a threaded rod 11. The outer side of the threaded rod 11 is threadedly connected with a moving block 12. Both sides of the moving block 12 are rotatably connected with a connecting rod 13. The ends of the connecting rod 13 away from the moving block 12 are rotatably connected with the second rotating rod 5. At the bottom end of the mounting plate 10, a stepping motor 15 is fixedly installed. The driving end of the stepping motor 15 is fixedly connected with the threaded rod 11.

[0019] By adopting the above technical solution, the stepping motor 15 drives the threaded rod 11 to rotate, which can drive the moving block 12 to move vertically along the outer side of the threaded rod 11, and at the same time drive the bottom end of the connecting rod 13 to move synchronously. When the bottom end of the connecting rod 13 moves vertically, the fixed rod 3 is used to limit one end of the first rotating rod 4 and the second rotating rod 5, and at the same time drive the first rotating rod 4 and the second rotating rod 5 to rotate around the central axis of the fixed rod 3, and make the limiting rod 6 slide along the inside of the arc-shaped groove 7, so as to drive the water delivery pipe 8 to swing reciprocally around the side of the dewatering machine body 2, realizing the cleaning of the side of the dewatering machine body 2.

[0020] On the top end of the mounting plate 10, close to one side of the threaded rod 11, a guide rod 14 is fixedly connected. The moving block 12 is slidably clamped on the outer side of the guide rod 14.

[0021] By adopting the above technical solution, by setting the guide rod 14, it is convenient to guide the vertical movement of the moving block 12, so as to ensure that the moving block 12 can stably move vertically while the threaded rod 11 rotates.

[0023] By adopting the above technical solution, by setting the drain pipe 17, it is convenient to drain the water body from the inside of the mounting frame 1.

[0024] The bottom end of the mounting frame 1 is fixedly connected with a bottom plate 19.

[0025] By adopting the above technical solution, by setting the bottom plate 19, it is convenient to place the equipment more stably.

[0026] One side of the mounting frame 1 and above the drain pipe 17 is fixedly installed with a PLC controller 20. The PLC controller 20 is electrically connected with the stepping motor 15.

[0027] By adopting the above technical solution, by setting the PLC controller 20, it is convenient to better control the equipment to work.

[0028] Working principle: After the spiral sludge dewatering machine is used for a period of time, it needs to be cleaned regularly. During cleaning, the stepping motor 15 drives the threaded rod 11 to rotate. By using the guide rod 14 to guide the moving block 12, the moving block 12 can be driven to move vertically along the outside of the threaded rod 11, and at the same time, the bottom end of the connecting rod 13 is driven to move synchronously. When the bottom end of the connecting rod 13 moves vertically, the fixed rod 3 is used to limit one ends of the rotating rod one 4 and the rotating rod two 5, and at the same time, the rotating rod one 4 and the rotating rod two 5 are driven to rotate around the central axis of the fixed rod 3, and the limiting rod 6 is driven to slide along the inside of the arc groove 7, so as to drive the water delivery pipe 8 to swing reciprocally around the side of the dewatering machine body 2, realizing the cleaning of the side of the dewatering machine body 2.

[0029] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention is also intended to include these modifications and variations.
