[0024] The sludge removal device for wastewater treatment includes: a treatment tank 1; a sludge-holding frame 2, which is located inside the treatment tank 1 and has multiple drainage holes, with a filter cloth 3 on its inner wall; a mounting frame 5, which is mounted on the treatment tank 1; a sludge suction mechanism, which is mounted on the treatment tank 1 and is used to extract sludge from the sedimentation tank; and a sludge pressing mechanism, which is mounted on the treatment tank 1 and is used to squeeze out water from the sludge. The sludge suction mechanism automatically extracts sludge from the sedimentation tank, eliminating the need for manual cleaning of the sludge at the bottom of the sedimentation tank, significantly reducing the labor intensity of workers. The drainage holes on the sludge-holding frame 2 and the filter cloth 3 on its inner wall allow for the initial drainage of water from the sludge. Combined with the sludge pressing mechanism, the water in the sludge can be effectively removed, improving the efficiency and quality of sludge treatment and reducing the workload of subsequent treatment.

[0025] The sludge suction mechanism includes a sludge suction pump 6, a telescopic sludge suction pipe 7, and a sludge discharge hose 8. The sludge suction pump 6 is fixedly installed on one side of the treatment tank 1. The telescopic sludge suction pipe 7 is fixedly connected to the inlet end of the sludge suction pump 6. The sludge discharge hose 8 is fixedly connected to the outlet end of the sludge suction pump 6. The outlet end of the sludge discharge hose 8 extends into the treatment tank 1 and is connected to the sludge holding frame 2. Using the sludge suction pump 6 as a power source, the sludge in the sedimentation tank can be quickly and efficiently extracted and transported to the sludge holding frame 2 through the sludge discharge hose 8, which greatly improves the sludge suction efficiency and shortens the time for cleaning the sedimentation tank. The telescopic sludge suction pipe 7 and the sludge discharge hose 8 allow the device to be stretched and adjusted according to the actual situation.

[0026] The sludge pressing mechanism includes a hydraulic rod 9 and a sludge pressing plate 10. The hydraulic rod 9 is fixedly installed on the processing box 1, and the sludge pressing plate 10 is located on the output rod of the hydraulic rod 9. The sludge pressing plate 10 is located above the sludge holding frame 2. The hydraulic rod 9 can provide greater pressure, which drives the sludge pressing plate 10 to squeeze the sludge in the sludge holding frame 2. This can effectively squeeze out the residual water in the sludge, improve the dewatering effect of the sludge, and facilitate subsequent transportation and processing.

[0027] Rotating rods 11 are rotatably mounted on both sides of the treatment box 1. A rotating motor 12 is fixedly mounted on one side of the treatment box 1. The two rotating rods 11 are respectively fixed to both sides of the sludge holding frame 2. One end of the rotating rod 11 is connected to the output shaft of the rotating motor 12 through a coupling. The rotating motor 12 drives the rotating rods 11 to rotate the sludge holding frame 2, realizing the automated operation of sludge discharge. There is no need for manual cleaning of sludge in the sludge holding frame 2, which further reduces the labor intensity of workers and improves work efficiency.

[0028] The mounting frame 5 is equipped with an electric telescopic rod 13, and the output rod of the electric telescopic rod 13 is equipped with a connecting rod 14. The connecting rod 14 is connected to the telescopic suction pipe 7, and the bottom end of the connecting rod 14 is equipped with a scraper 15. The electric telescopic rod 13, the connecting rod 14, the telescopic suction pipe 7 and the scraper 15 cooperate with each other to form an organic whole, realizing the coordinated operation of scraping and suction.

[0029] A drive motor 16 is fixedly installed on one side of the mounting frame 5. A transverse screw 17 is rotatably installed on the mounting frame 5. One end of the transverse screw 17 is connected to the output shaft of the drive motor 16 via a coupling. A slide block 18 is threaded onto the transverse screw 17. The slide block 18 is connected to the electric telescopic rod 13. The slide block 18 slides against the inner wall of the mounting frame 5. The drive motor 16 drives the transverse screw 17 to rotate, causing the slide block 18 and the electric telescopic rod 13 to move laterally. This allows the sludge suction mechanism to move flexibly in the width direction of the sedimentation tank, expanding the sludge suction range and enabling the cleaning of sludge in various locations within the sedimentation tank, thus improving the comprehensiveness of the cleaning process.

[0030] A cleaning port is provided on one side of the treatment box 1. A sealing door is hinged to the cleaning port. Through the cleaning port, the operator can conduct a comprehensive inspection and maintenance of the various components inside the treatment box 1, and can also clean the filter cloth 3.

[0031] It is worth noting that the circuits, electronic components, and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0032] The working principle of the sludge removal device for sewage treatment provided by this utility model is as follows:

[0033] This solution also includes an electrical control cabinet, which is installed on the equipment. During use, each piece of electrical equipment can be started and operated separately through the electrical control cabinet. The power connection method of each piece of electrical equipment is an existing mature technology and is well known to those in the field, so it will not be described in detail here.

[0034] When in use, adjust the telescopic suction pipe 7 to a suitable length according to the distribution and depth of sludge in the sedimentation tank, start the electric telescopic rod 13, the output rod of the electric telescopic rod 13 begins to extend and retract, and the connecting rod 14 will drive the telescopic suction pipe 7 and the scraper 15 to move up and down with the extension and retraction of the output rod of the electric telescopic rod 13 until the scraper 15 contacts the sedimentation tank.

[0035] Start the sludge suction pump 6. The sludge suction pump 6 starts working. Under the action of the sludge suction pump 6, the sludge in the sedimentation tank is sucked into the inlet end of the sludge suction pump 6 through the telescopic sludge suction pipe 7. The sludge sucked into the sludge suction pump 6 enters the fixed and connected sludge discharge hose 8 from the discharge end. The sludge discharge hose 8 transports the sludge to the treatment tank 1 and finally discharges it into the sludge collection frame 2 connected to the discharge end of the sludge discharge hose 8. During the sludge suction process, turn on the drive motor 16. The drive motor 16 starts working and its output shaft starts to rotate. The rotation of the output shaft of the drive motor 16 will drive the transverse screw 17 to rotate. When the transverse screw 17 rotates, the slide 18 will move laterally along the axis of the transverse screw 17. During the transverse movement of the slide 18, it will drive the telescopic sludge suction pipe 7 and the scraper 15 to move, so as to thoroughly clean the sludge in the sedimentation tank.

[0036] When the sludge suction mechanism pumps the sludge from the sedimentation tank into the sludge holding frame 2, and after a period of drainage, it is ready to perform the sludge pressing operation. The hydraulic rod 9 is activated and starts working, with its output rod extending. Since the sludge pressing plate 10 is located on the output rod of the hydraulic rod 9, as the output rod of the hydraulic rod 9 extends, the sludge pressing plate 10 moves downward and gradually approaches the sludge in the sludge holding frame 2. When the sludge pressing plate 10 contacts the sludge, it continues to press down, applying pressure to the sludge and further squeezing out the water in the sludge. The squeezed water is discharged through the outlet 4. After the squeezing is completed, the output rod of the hydraulic rod 9 is retracted, driving the sludge pressing plate 10 to move upward and return to the initial position, waiting for the next sludge pressing operation.

[0037] After the sludge pressing mechanism completes the squeezing and dewatering operation of the sludge in the sludge holding frame 2, it is ready to pour the dewatered sludge out of the sludge holding frame 2. The rotating motor 12 is turned on and starts to work. Its output shaft starts to rotate. The rotation of the output shaft of the rotating motor 12 will drive the rotating rod 11 to rotate. As the rotating rod 11 rotates, the sludge holding frame 2 will also flip over, and the dewatered sludge inside will be poured out of the treatment box 1 from the discharge port 4. After the sludge is poured out, the rotating motor 12 is controlled to rotate in the opposite direction, so that the rotating rod 11 drives the sludge holding frame 2 to flip back to the initial position, waiting for the next sludge suction and sludge pressing operation.

[0038] Compared with related technologies, the sludge removal device for sewage treatment provided by this utility model has the following beneficial effects:

[0039] This invention provides a sludge removal device for wastewater treatment. The sludge suction mechanism automatically extracts sludge from the sedimentation tank, eliminating the need for manual cleaning of the bottom of the sedimentation tank and significantly reducing labor intensity. The drainage holes on the sludge-holding frame 2 and the filter cloth 3 on the inner wall allow for initial drainage of water from the sludge. Combined with the sludge pressing mechanism, the sludge is squeezed, effectively removing moisture and improving the efficiency and quality of sludge treatment, while reducing subsequent processing workload. The sludge suction pump 6 serves as the power source, quickly and efficiently extracting sludge from the sedimentation tank and transporting it to the sludge-holding frame 2 via the sludge discharge hose 8, greatly improving suction efficiency and shortening the time required to clean the sedimentation tank. The extendable suction pipe 7 and discharge hose 8 allow the device to be adjusted according to actual conditions. The hydraulic rod 9 provides significant pressure, driving the sludge pressing plate 10 to squeeze the sludge in the sludge-holding frame 2, effectively squeezing out any residual sludge. Moisture removal improves sludge dewatering, facilitating subsequent transportation and processing. The rotating rod 11, driven by the rotating motor 12, rotates the sludge container 2, achieving automated sludge discharge. This eliminates the need for manual cleaning of the sludge in the container 2, further reducing labor intensity and increasing efficiency. The electric telescopic rod 13, connecting rod 14, telescopic suction pipe 7, and scraper 15 work together to form an integrated system, enabling coordinated scraping and suction. The drive motor 16 rotates the transverse screw 17, causing the slide 18 and electric telescopic rod 13 to move laterally, allowing the suction mechanism to move flexibly across the width of the sedimentation tank. This expands the suction range, enabling the cleaning of sludge in various locations within the sedimentation tank and improving the comprehensiveness of the cleaning process. Through the cleaning port, operators can perform comprehensive inspection and maintenance of all components inside the treatment tank 1 and clean the filter cloth 3.
