Abstract
Description
Technical Field
[0001] This application relates to the field of sludge extraction equipment technology, and in particular to a high-concentration sludge pumping device. Background Technology
[0002] With the continuous upgrading of my country's environmental protection standards and the advancement of the "dual carbon" target, sludge treatment has become one of the most technologically intensive links in the wastewater treatment industry chain. Sludge contains a large amount of organic matter and pathogens, and if not properly treated, it will cause secondary pollution to the environment, affecting the self-purification capacity of water bodies and the flood control capacity of cities. Current technologies generally use submersible sludge pumps to extract sludge.
[0003] During the sludge extraction process, the sludge medium is often mixed with solid impurities such as sand and gravel. These impurities will directly enter the pump body with the fluid, thereby blocking the pump's internal flow channel, reducing the pump's outlet pressure and flow rate, and even causing damage to the pump body. Therefore, an improvement has been made to a high-concentration sludge pumping device. Utility Model Content
[0004] To address the shortcomings of existing technologies, this application provides a high-concentration sludge pumping device, which overcomes the deficiencies of existing technologies and aims to solve the problem that sand, gravel, and other debris in the sludge will clog the flow channel inside the pump during the sludge pumping process.
[0005] To achieve the above objectives, this application provides the following technical solution: a high-concentration sludge pumping device, comprising a placement plate, a sludge pump fixedly installed at the center of the upper surface of the placement plate, and stirring units symmetrically installed on both sides of the sludge pump on the upper surface of the placement plate. The input end of the sludge pump passes through the placement plate and extends below it, and the output end of the sludge pump is fixedly connected to a sludge pipe via a flange. A fixing seat is fixedly installed on the lower surface of the placement plate outside the input end of the sludge pump. A filter cover is provided inside the fixing seat, and a connecting block is fixedly connected to the outer wall of the filter cover. An adjustment groove and a connecting groove are opened on the inner wall of the fixing seat outside the filter cover. A return spring is fixedly connected inside the adjustment groove, and an adjustment block is fixedly connected to the other end of the return spring. The adjustment block slides up and down inside the adjustment groove, and the connecting block is slidably inserted into the inside of the connecting groove.
[0006] By adopting the above technical solution, after aligning the filter cover with the fixed base, press the filter cover to make the connecting block squeeze the adjusting block, forcing the adjusting block to compress the return spring and move in its direction. At this time, the inlet of the connecting groove is opened. Rotate the filter cover to make the connecting block slide into the connecting groove. When the connecting block is fully inserted into the connecting groove, the return spring releases its elastic force to push the adjusting block to return to its original position, automatically closing the opening of the connecting groove and completing the mechanical locking. This completes the quick installation of the filter cover, thus fixing the filter cover on the outside of the suction end of the sludge pump. Large particles of debris can be filtered through the filter cover to prevent these debris from being sucked into the sludge pump. The stirring unit pre-treats the sludge with shear force to reduce the concentration of solid debris. The two work together to reduce the risk of pump blockage.
[0007] As a preferred technical solution of this application, the inner wall of the fixed seat is provided with a limiting groove on one side of the adjusting groove, and a T-shaped block adapted to the limiting groove is fixedly connected to the outer wall of the adjusting block near the limiting groove. The T-shaped block slides up and down inside the limiting groove.
[0008] By adopting the above technical solution, the movement path of the adjusting block is limited by the cooperation between the T-block and the limiting groove, ensuring that the adjusting block will not deviate in position when moving, and guaranteeing the accuracy of the adjusting block's movement.
[0009] As a preferred technical solution of this application, the number of the adjustment groove, reset spring, adjustment block, limit groove, T-shaped block, connecting groove and connecting block are all four and correspond one-to-one. The four adjustment grooves are evenly distributed in a circular array inside the fixed base.
[0010] By adopting the above technical solution, the four locking structures are evenly distributed in a circular array, which realizes the stable installation of the filter cover and enables the fluid pressure borne by the filter cover to be evenly transmitted to the fixed base, avoiding deformation caused by local stress concentration. The four connecting slots in the circular array constitute a mechanical guiding system. During installation, the filter cover is rotated to automatically align the insertion points, which facilitates installation.
[0011] As a preferred technical solution of this application, the top of the fixing base is provided with a mounting hole, and a mounting bolt is slidably inserted into the mounting hole. The front end of the mounting bolt is located inside the shelf and is threadedly connected to it.
[0012] By adopting the above technical solution, the fixing seat is fixedly installed on the bottom of the shelf by mounting bolts.
[0013] As a preferred technical solution of this application, the stirring unit includes a stirring motor fixedly installed on the surface of the shelf, the output end of the stirring motor extends through the shelf and below it and is fixedly connected to a spiral stirring blade, the stirring blade of the spiral stirring blade is inclined.
[0014] By adopting the above technical solution, the spiral agitator is driven by the stirring motor to rotate. The stirring blades on the spiral agitator generate axial thrust when rotating, pushing the sludge towards the sludge suction pump for suction. In addition, the spiral agitator can pre-treat the sludge through shearing force when rotating, reducing the concentration of solid impurities.
[0015] As a preferred technical solution of this application, a U-shaped frame is fixedly welded to the side wall of the shelf, and a hanging ring is fixedly welded to the top of the U-shaped frame.
[0016] By adopting the above technical solution, the lifting ring is set to facilitate the lifting of the device by the crane. The lifting ring is located at the top of the U-shaped frame and is vertically aligned with the center of gravity of the device, which can prevent tilting and swaying during lifting.
[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0018] In this invention, after aligning the filter cover with the fixed base, press the filter cover to cause the connecting block to squeeze the adjusting block, forcing the adjusting block to compress the return spring and move in its direction. At this time, the inlet of the connecting groove is opened. Rotate the filter cover to make the connecting block slide into the connecting groove. When the connecting block is fully inserted into the connecting groove, the return spring releases its elastic force to push the adjusting block to return to its original position, automatically closing the opening of the connecting groove and completing the mechanical locking. This completes the quick installation of the filter cover, thus fixing the filter cover on the outside of the suction end of the sludge pump. Large particles of debris can be filtered through the filter cover to prevent these debris from being sucked into the sludge pump. The stirring unit pre-treats the sludge with shear force to reduce the concentration of solid debris. The two work together to reduce the risk of pump blockage.

Detailed Implementation
[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0027] like Figure 1 - Figure 4 As shown, this embodiment provides a high-concentration sludge pumping device, including a placement plate 1. A sludge pump 4 is fixedly installed at the center of the upper surface of the placement plate 1. A stirring unit 5 is symmetrically installed on both sides of the sludge pump 4 on the upper surface of the placement plate 1. The input end of the sludge pump 4 passes through the placement plate 1 and extends below it. The output end of the sludge pump 4 is fixedly connected to a sludge pipe 7 via a flange 6. A fixing seat 8 is fixedly installed on the lower surface of the placement plate 1 outside the input end of the sludge pump 4. A filter cover 17 is provided inside the fixing seat 8. A connecting block 18 is fixedly connected to the outer wall of the filter cover 17. An adjustment groove 9 and a connecting groove 14 are opened on the inner wall of the fixing seat 8 outside the filter cover 17. A return spring 10 is fixedly connected inside the adjustment groove 9. An adjustment block 11 is fixedly connected to the other end of the return spring 10. The adjustment block 11 slides up and down inside the adjustment groove 9. The connecting block 18 slides into the adjustment groove 9. When connected to the inside of the connecting groove 14, during use, after aligning the filter cover 17 with the fixing seat 8, press the filter cover 17 to make the connecting block 18 squeeze the adjusting block 11, forcing the adjusting block 11 to compress the return spring 10 and move in its direction. At this time, the inlet of the connecting groove 14 is opened. Rotate the filter cover 17 to make the connecting block 18 slide into the connecting groove 14. When the connecting block 18 is fully inserted into the connecting groove 14, the return spring 10 releases its elastic force to push the adjusting block 11 to reset, automatically closing the opening of the connecting groove 14 and completing the mechanical locking. This completes the quick installation of the filter cover 17, thereby fixing the filter cover 17 on the outside of the suction end of the sludge pump 4. Large particles of debris can be filtered through the filter cover 17 to prevent these debris from being sucked into the sludge pump 4. The stirring unit 5 pre-treats the sludge with shear force to reduce the concentration of solid debris. The two work together to reduce the risk of pump blockage.
[0028] In this embodiment, as Figure 2 and 3As shown, a limiting groove 12 is provided on one side of the inner wall of the fixed base 8, near the adjusting groove 9. A T-shaped block 13 that matches the limiting groove 12 is fixedly connected to the outer wall of the adjusting block 11 near the limiting groove 12. The T-shaped block 13 slides up and down inside the limiting groove 12. In use, the movement path of the adjusting block 11 is limited by the cooperation between the T-shaped block 13 and the limiting groove 12, ensuring that the adjusting block 11 will not deviate in position when moving, thus ensuring the accuracy of the movement of the adjusting block 11.
[0029] In this embodiment, as Figure 2 and 3 As shown, there are four of each of the following components: adjustment groove 9, reset spring 10, adjustment block 11, limit groove 12, T-block 13, connecting groove 14, and connecting block 18. The four adjustment grooves 9 are evenly distributed in a circular array inside the fixed base 8. During use, the four locking structures are evenly distributed in a circular array to achieve stable installation of the filter cover 17 and to ensure that the fluid pressure borne by the filter cover 17 is evenly transmitted to the fixed base 8, avoiding deformation caused by local stress concentration. The four connecting grooves 14 in the circular array constitute a mechanical guiding system. During installation, the filter cover 17 is rotated to automatically align the insertion points, which is convenient for installation.
[0030] In this embodiment, as Figure 1 and 2 As shown, the top of the fixing base 8 is provided with a mounting hole 15, and a mounting bolt 16 is slidably inserted into the mounting hole 15. The front end of the mounting bolt 16 is inside the shelf 1 and is threadedly connected to it. In use, the fixing base 8 is fixedly installed on the bottom of the shelf 1 by the mounting bolt 16.
[0031] In this embodiment, as Figure 1 and 4 As shown, the stirring unit 5 includes a stirring motor 51 fixedly installed on the upper surface of the placement plate 1. The output end of the stirring motor 51 extends through the placement plate 1 to its lower part and is fixedly connected to a spiral stirring paddle 52. The stirring blades of the spiral stirring paddle 52 are inclined. In use, the stirring motor 51 drives the spiral stirring paddle 52 to rotate. When rotating, the stirring blades on the spiral stirring paddle 52 generate axial thrust, pushing the sludge towards the sludge suction pump 4 for suction. The spiral stirring paddle 52 can pre-treat the sludge through shear force when rotating, reducing the concentration of solid impurities.
[0032] In this embodiment, as Figure 1 As shown, a U-shaped frame 2 is fixedly welded to the side wall of the shelf 1, and a lifting ring 3 is fixedly welded to the top of the U-shaped frame 2. In use, the lifting ring 3 facilitates the lifting of the device by a crane. The lifting ring 3 is located at the top of the U-shaped frame 2 and is vertically aligned with the center of gravity of the device, which can prevent tilting and swaying during hoisting.
[0033] The working principle of this utility model is as follows: When using the high-concentration sludge pumping device of this application, after aligning the filter cover 17 with the fixed base 8, press the filter cover 17 to cause the connecting block 18 to squeeze the adjusting block 11, forcing the adjusting block 11 to compress the return spring 10 and move in its direction. At this time, the inlet of the connecting groove 14 is opened. Rotating the filter cover 17 causes the connecting block 18 to slide into the connecting groove 14. When the connecting block 18 is completely inserted into the connecting groove 14, the return spring 10 releases its elastic force to push the adjusting block 11 to return to its original position, automatically closing the connecting groove 14. 4. After opening and mechanical locking, the filter cover 17 can be quickly installed. After installation, the device is lifted into the sewage by a crane. The sludge pump 4 is started to suck up the sludge, which is then transported to the shore through the sludge pipe 7. The stirring motor 51 drives the spiral stirring blade 52 to rotate. The stirring blades on the spiral stirring blade 52 generate axial thrust when rotating, pushing the sludge towards the sludge pump 4 for it to suck up. The filter cover 17 filters out large particles of debris, preventing these debris from being sucked into the sludge pump 4 and avoiding blockage of the sludge pump 4.
