Technical Field

[0001] This utility model relates to the field of sludge treatment technology, specifically to an automatic sludge scraping device for a high-pressure belt sludge dewatering machine. Background Technology

[0002] Sludge treatment is a process of reducing, stabilizing, and rendering harmless sludge through concentration, conditioning, dewatering, stabilization, drying, or incineration. The aim is to reduce sludge volume, stabilize sludge properties, kill pathogens, and achieve resource utilization. High-pressure belt sludge dewatering machines are devices that use continuous high-pressure, high-shear pressing technology to achieve solid-liquid separation of sludge through physical pressing. They can effectively reduce the sludge moisture content to below 60%, offering advantages such as high dewatering efficiency, high automation, and stable operation. They are widely used in municipal sewage treatment, industrial wastewater treatment, and mine tailings dry disposal. High-pressure belt sludge dewatering machines utilize two continuously running filter belts to sandwich flocculated sludge, which is then pressurized by rollers of various arrangements to achieve dewatering.

[0003] If a high-pressure belt sludge dewatering machine does not have a sludge scraping device, the deposits on the sludge plate need to be cleaned manually and regularly. This not only increases the labor intensity, but may also lead to a decrease in dewatering efficiency due to untimely cleaning. Summary of the Invention

[0022] Specifically, the drive structure 4 can be used to drive the scraper structure 5 to rotate, and then the top of the mud discharge plate 2 can be cleaned by the scraper structure 5.

[0023] Furthermore, as the mud discharge plate 2 rotates, the drive structure 4 can be activated, and then the drive structure 4 drives the scraping structure 5 to rotate, so that the mud discharge plate 2 can be cleaned by the scraping structure 5.

[0024] Example 2, the second embodiment of this utility model, the drive structure 4 includes a motor 401, a first drive wheel 402, a second drive wheel 403 and a transmission belt 404. The motor 401 is fixedly connected to the top of the shield 3, the first drive wheel 402 is fixedly connected to the output end of the motor 401, the second drive wheel 403 is rotatably connected to the inner side of the desliming machine 1 and is located on the top of the mud discharge plate 2, the transmission belt 404 is sleeved on the surface of the first drive wheel 402 and the second drive wheel 403, and the mud scraping structure 5 is disposed on the front side of the second drive wheel 403.

[0025] Specifically, the drive structure 4 can be used to drive the scraper structure 5 to rotate, and then the scraper structure 5 can clean the mud discharge plate 2.

[0026] Furthermore, the motor 401 is started, which drives the first drive wheel 402 to rotate. When the first drive wheel 402 rotates, it can drive the second drive wheel 403 to rotate through the transmission belt 404.

[0027] Example 3, the third embodiment of this utility model, the sludge scraping structure 5 includes a rotating rod 501 and a cleaning wheel 502.

When the first drive wheel 402 rotates, it can drive the second drive wheel 403 to rotate through the transmission belt 404. The rotation of the second drive wheel 403 can drive the rotating rod 501 to rotate. Then, the rotation of the rotating rod 501 can drive the cleaning wheel 502 to rotate. Then, the surface of the mud discharge plate 2 can be cleaned by the cleaning wheel 502. When the cleaning wheel 502 rotates, the surface of the cleaning wheel 502 can be cleaned by the scraper 7.
