Technical Field

[0001] This utility model relates to the field of cleaning device technology, specifically a cleaning device for tension screen plates and raw coal grading screen plates. Background Technology

[0002] Both coal grading screens and tension screens are screening equipment. When the moisture content is high and the gangue is muddy, the coal is prone to clump together. During the screening process, finer coal mud is easy to adhere to the screen plate of the raw coal grading screen or tension screen, which can easily clog the screen holes, significantly reduce the screening efficiency, and worsen the screening effect.

[0003] The current method of cleaning screen plates is to use manual labor, which often increases labor costs, is inefficient, has poor cleaning results, and is inconvenient for fixing the screen plates.

[0004] To address the aforementioned issues, a cleaning device for tension screen plates and raw coal grading screen plates is proposed. Utility Model Content

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] This utility model provides a cleaning device for tension screen plates and raw coal grading screen plates. A screw rotation drives a moving base and a brush below to move horizontally. The brush cleans the surface of the screen plate, and the use of a scraper further enhances the cleaning effect. A water pump draws water from the tank through a water pipe and sprays it through nozzles to rinse the screen plate and prevent dust generation during cleaning. A lifting assembly allows for the raising and lowering of the fixed plate and brush, enabling height adjustment as needed. Turning a knob brings the two clamps on the left and right sides closer together to secure the screen plate, preventing movement during cleaning and enhancing its practicality.

[0030] Reference Figure 1-3This utility model discloses a cleaning device for tension screen plates and raw coal grading screen plates, including a cleaning platform 1 for placing the screen plates to be cleaned. A support plate 2 is fixedly connected to the rear end of the cleaning platform 1, providing support. A top plate 3 is fixedly connected to the top of the support plate 2, and an installation groove 4 is provided at the bottom of the top plate 3, serving as a limiting position. A lead screw 5 is threaded through and rotatably connected within the installation groove 4. A movable seat 7 is threaded onto the outer ring of the lead screw 5, and a lifting assembly is connected to the bottom of the movable seat 7. A fixed plate 12 is connected to the bottom of the lifting assembly, providing both fixation and support. A brush 13 is fixedly connected to the bottom of the fixed plate 12, enabling cleaning of the screen plates. A scraper 14 is fixedly connected to the outer side of the fixed plate 12, removing stubborn dirt. A diversion pipe 17 is fixedly connected to the outer side of the scraper 14, and multiple nozzles 18 are installed on the outside of the diversion pipe 17, spraying water through the nozzles 18. A water tank 15 is fixedly connected to the rear top of the fixed plate 12, and the water tank 15 is used to store water. A water pump 16 is fixedly connected to the front top of the fixed plate 12, and water pipes 19 are fixedly connected to both ends of the water pump 16. The water pipes 19 are flexible hoses. The top of the cleaning platform 1 has evenly distributed water outlet holes 20. A collection box (not shown in the figure) is set below the water outlet holes 20 of the cleaning platform 1 to collect wastewater. Two fixed seats 21 are fixedly connected to the left and right sides of the top of the cleaning platform 1. A threaded rod 22 is threaded through and connected to the fixed seat 21. A clamping plate 23 is rotatably connected to one end of the threaded rod 22. The top of the fixed seat 21 and the clamping plate 23 are flush with the screen plate to ensure the cleaning effect of the screen plate.

[0031] Reference Figure 2 The lifting assembly includes a fixed cylinder 8, the top of which is fixedly connected to a movable seat 7. A lifting groove 9 is provided at the bottom of the fixed cylinder 8. A hydraulic cylinder 10 is fixedly connected inside the lifting groove 9. A lifting column 11 is fixedly connected to the output end of the hydraulic cylinder 10. The bottom of the lifting column 11 is fixedly connected to a fixed plate 12. The lifting column 11 is set inside the lifting groove 9, and the outside of the lifting column 11 is slidably connected to the inner wall of the lifting groove 9. The lifting assembly can drive the fixed plate 12 and the brush 13 to rise and fall, thereby allowing the height of the fixed plate 12 and the brush 13 to be adjusted as needed.

[0032] Reference Figure 1-3A motor 6 is fixedly connected to the left side of the top plate 3, and the output end of the motor 6 is fixedly connected to the lead screw 5. The motor 6 can drive the lead screw 5 to rotate. The movable seat 7 is set in the mounting groove 4, and the outside of the movable seat 7 is slidably connected to the inner wall of the mounting groove 4. The mounting groove 4 serves to limit the movement of the movable seat 7. The end of the water inlet pipe 19 passes through and is fixedly connected to the water tank 15, and the end of the water outlet pipe 19 passes through and is fixedly connected to the diversion pipe 17. The water pipe 19 serves to transport water. An anti-slip plate 24 is fixedly connected to the outside of the clamping plate 23. The anti-slip plate 24 can better clamp the screen plate. A knob 25 is fixedly connected to one end of the threaded rod 22, and the knob 25 is set outside the fixed seat 21. The knob 25 can drive the threaded rod 22 to rotate.

[0033] Working Principle: First, place the screen plate to be cleaned on the cleaning table 1. By rotating the knob 25 on the threaded rod 22, the threaded rod 22 rotates within the fixed seat 21, causing the clamping plate 23 to move inward. The anti-slip plate 24 on the outside of the clamping plate 23 firmly clamps the screen plate, preventing it from moving during cleaning. Next, start the motor 6. The output end of the motor 6 drives the lead screw 5 to rotate within the mounting groove 4 of the top plate 3. Since the moving seat 7 is threadedly connected to the lead screw 5 and slides within the mounting groove 4, the rotation of the lead screw 5 drives the moving seat 7 to move laterally within the mounting groove 4. Simultaneously, the lifting assembly fixed to the bottom of the moving seat 7 begins to work. The hydraulic cylinder 10 of the fixed cylinder 8 starts, and its output end pushes the lifting column 11 to slide up and down within the lifting groove 9, thereby driving the fixed plate 12 to rise and fall, allowing the brush 13 and scraper 14 at the bottom of the fixed plate 12 to be adjusted to a suitable height according to cleaning requirements. When the brush 13 and scraper 14 descend to contact the screen plate, the water pump 16 is started. Water pump 16 draws water from water tank 15 through inlet pipe 19, and delivers it to diversion pipe 17 through outlet pipe 19. The water is then sprayed out by multiple nozzles 18 on diversion pipe 17 to rinse the screen plate. Meanwhile, movable seat 7 moves fixed plate 12 laterally. Brush 13 scrubs the screen plate surface during this movement, while scraper 14 removes stubborn dirt. The scrubbed impurities are discharged with the water flow through outlet hole 20 at the top of cleaning platform 1.
