Description

Technical Field

[0001] This application relates to the field of mining engineering technology, and in particular to a rapid cleaning device for inclined tubes in sedimentation tanks of sewage treatment plants. Background Technology

[0002] High-efficiency sedimentation tanks, as a key solid-liquid separation device, are widely used in municipal sewage treatment, industrial wastewater treatment, and water purification in waterworks due to their advantages of small footprint and high sedimentation efficiency. Inclined tube packing, as a core component of high-efficiency sedimentation tanks, forms a dense, inclined tubular structure that utilizes shallow sedimentation principles to significantly shorten particle settling distance, thereby significantly improving the treatment capacity and separation effect of the sedimentation tank. However, during long-term operation, suspended particles, microorganisms, algae, and calcium and magnesium ions easily adhere to the surface of the inclined tube packing. These deposits gradually clog the gaps between the inclined tubes, leading to increased flow resistance and reduced flow area, severely affecting the hydraulic conditions and sedimentation efficiency of the sedimentation tank. If not cleaned in time, it will not only reduce the water treatment effect but may also cause problems such as short-circuiting of water flow and sludge accumulation due to local blockage, and may even require shutdown for maintenance, increasing operating costs and maintenance burden.

[0003] Currently, manual cleaning requires operators to enter the sedimentation tank and disassemble the inclined tubes piece by piece for wiping or rinsing. This is not only labor-intensive and inefficient, but also poses certain safety hazards, especially in large sedimentation tanks or environments with poor water quality, where the operation is extremely difficult. While high-pressure water rinsing eliminates the need to disassemble the inclined tubes, the water flow direction and pressure of traditional rinsing equipment are difficult to control precisely, easily leading to cleaning dead zones. It has limited effectiveness in removing firmly attached sediments from the inner wall of the inclined tubes, and excessive pressure may damage the inclined tube structure. Utility Model Content

[0005] To achieve the above objectives, this application provides a rapid cleaning device for inclined tubes in sedimentation tanks of wastewater treatment plants, comprising a high-efficiency sedimentation tank body with a treatment chamber on its inner arc surface. An inclined tube is fitted onto the inner arc surface of the treatment chamber. The sedimentation chamber has its inner sidewall located on the bottom surface of the high-efficiency sedimentation tank body, and the sedimentation chamber and treatment chamber are in the same plane. A spray chamber tube has an inclined plate fixedly installed on the top of one end face. One side of the inclined plate is fixedly installed on the top of the high-efficiency sedimentation tank body by bolts. A connecting test tube is connected at one end to the spray chamber tube. A connecting shaft is placed inside the treatment chamber. A pressure head has its upper end face connected to the other end of the connecting test tube. A fixing ring has its outer arc surface fitted onto the bottom of the inner arc surface of the connecting shaft. A water distributor is fitted into the inner arc surface of the fixing ring. The outer arc surface of the water distributor is adapted to the inner arc surface of the inclined tube. One end of the connecting shaft is placed in the treatment chamber of the high-efficiency sedimentation tank body.

[0006] Optionally, the ejection chamber includes a water inlet, one side of which is located at the top of the outer arc surface of the ejection chamber, a compression spring, and the bottom end is placed on the surface of the high-efficiency sedimentation tank.

[0007] Optionally, a pressure sleeve rod is sleeved on the inner arc surface of the compression spring, and one end of the pressure sleeve rod is adapted to the inner arc surface of the ejection chamber.

[0008] Optionally, the connecting shaft includes connecting blocks disposed on the outer arc surface of the connecting shaft. The number of connecting blocks is several, and they are evenly distributed on the connecting shaft in a ring array. A scraper blade is disposed on one end face of the connecting block.

[0009] Optionally, a micro motor module is sleeved on the inner arc surface of the connecting shaft, a bent scraping end is provided at the end of the scraper blade away from the connecting shaft, and one end of the connecting test tube extends into the interior of the packing inclined tube.

[0010] Optionally, the liquid-pressing head includes a liquid-suction cone, one end of which is installed in the inner arc surface of the connecting shaft, and a filter kit is fixedly installed on the upper surface of the liquid-suction cone.

[0011] Optionally, the surface of the filter kit is provided with a plurality of slots, the outer arc surface of the liquid pressure head is provided with a groove, and the inner arc surface of the groove is fitted into the upper end surface of the connecting block.

[0012] Optionally, a supply connector is sleeved on the upper surface of the liquid pressure head, and a supply nozzle is provided in the middle of the upper surface of the supply connector.

[0013] Optionally, the inner arc surface of the supply connector is sleeved on the connecting test tube, and the filter kit and the water distributor are in the same plane.

[0014] Optionally, the outer arc surface of the water distributor is fitted with a cloth holder, the cloth holder is sleeved inside the fixing ring, and the bent scraper end is attached to the inner arc surface of the packing inclined tube.

[0015] This application provides a rapid cleaning device for inclined tubes in sedimentation tanks of wastewater treatment plants. A compressed air sleeve, fitted with the inner arc surface of a compression spring, precisely matches the inner arc surface of the spray chamber. When the spring is compressed, the compressed air sleeve smoothly advances along the inner wall of the chamber, creating a uniform surface compression of the internal liquid. This avoids the liquid pressure fluctuations caused by uneven force in traditional piston-type compression. Simultaneously, during the pressure release phase, the compressed air sleeve pushes the liquid at a uniform speed as the spring rebounds, ensuring that the high-pressure liquid is delivered to the cleaning area through the connecting tube at a stable flow rate. This prevents uneven water distribution by the distributor due to sudden pressure changes, further guaranteeing consistent cleaning results. The device uses a connecting block fitted with the outer arc surface groove of the liquid-pressing head to rotate synchronously with the connecting shaft, ensuring that the liquid spray direction always aligns with the scraping direction of the scraper blades. The sediment just removed by the scraper blades is immediately flushed away by the high-pressure liquid sprayed from the liquid-pressing head, preventing secondary adhesion of sediment. By adapting the outer arc surface of the water distributor to the inner arc surface of the packing inclined tube, high-pressure liquid can be converted into a uniform ring or fan-shaped water flow. Combined with the design of the water distributor rotating synchronously with the connecting shaft, the water flow can cover every area of ​​the inner wall of the inclined tube, avoiding the problems of excessive local rinsing and local omissions caused by the concentrated water flow of traditional single-point high-pressure water guns. The rinsing uniformity is improved, ensuring that there are no residual impurities on the inner wall of the inclined tube.

[0025] like Figure 1 , Figure 2 and Figure 3 As shown in the figure, this application embodiment provides a rapid cleaning device for inclined tubes in sedimentation tanks of sewage treatment plants. This rapid cleaning device for inclined tubes in sedimentation tanks of sewage treatment plants includes a high-efficiency sedimentation tank body 1, a treatment chamber 101 on its inner arc surface, a packing inclined tube 102 fitted onto the inner arc surface of the treatment chamber 101, a sedimentation chamber 2, the inner sidewall of which is set on the bottom surface of the high-efficiency sedimentation tank body 1, the sedimentation chamber 2 and the treatment chamber 101 being in the same plane, a spray chamber pipe 3, an inclined plate 301 fixedly installed on the top of one end face, one side of the inclined plate 301 being fixedly installed on the top of the high-efficiency sedimentation tank body 1 by bolts, a connecting test tube 4, one end of which is connected to the spray chamber pipe 3, a connecting shaft 5 placed inside the treatment chamber 101, a pressure head 6, the upper end face of which is connected to the other end of the connecting test tube 4, a fixing ring 7, the outer arc surface of which is fitted onto the bottom of the inner arc surface of the connecting shaft 5, and a water distributor 8. The water distributor 8 is fitted into the inner arc surface of the fixing ring 7. The outer arc surface of the water distributor 8 is adapted to the inner arc surface of the packing inclined tube 102. One end of the connecting shaft 5 is placed in the treatment chamber 101 of the high-efficiency sedimentation tank body 1. The spray chamber tube 3 includes a water inlet 31, one side of which is set at the top of the outer arc surface of the spray chamber tube 3. The bottom end of the compression spring 32 is placed on the surface of the high-efficiency sedimentation tank body 1. The inner arc surface of the compression spring 32 is fitted with a compressed air sleeve 33. One end of the compressed air sleeve 33 is adapted to the inner arc surface of the spray chamber tube 3. The connecting shaft 5 includes a connecting block 51, which is set on the outer arc surface of the connecting shaft 5. There are several connecting blocks 51, which are evenly distributed on the connecting shaft 5 in a ring array. One end face of the scraper blade 52 is set in the connecting block 51.

[0026] The high-efficiency sedimentation tank 1, with its pre-designed treatment chamber 101 on its inner arc surface, defines a closed and fixed space for cleaning operations. All subsequent cleaning actions are carried out around the inner wall of the packing inclined tube 102 fitted onto the inner arc surface of the treatment chamber 101. Simultaneously, the top of the high-efficiency sedimentation tank 1 is fixed to the inclined plate 301 of the spray chamber pipe 3 by bolts, providing stable support for the spray chamber pipe 3 and preventing displacement of the pipe during subsequent high-pressure liquid transportation. The bottom surface of the high-efficiency sedimentation tank 1 provides an installation foundation for the sedimentation chamber 2, ensuring that the treatment chamber 101 and the sedimentation chamber 2 are on the same plane and reserving a path for impurity settling. Based on the fixed foundation provided by the high-efficiency sedimentation tank 1, external cleaning fluid flows through the spray chamber pipe... The water inlet 31 at the top of the outer arc surface injects liquid into the cavity tube. The top design of the water inlet 31 not only prevents liquid overflow but also facilitates connection to the external liquid supply system for rapid replenishment. Then, the compression spring 32 at the bottom of the ejection cavity tube 3 is squeezed. The spring stores elastic potential energy, and the air compression sleeve 33 sleeved on its inner side is pushed into the cavity tube as the spring is compressed. Because the air compression sleeve 33 is adapted to the inner arc surface of the cavity tube, it can evenly squeeze the internal liquid and raise the liquid pressure to the preset high pressure value to complete the power reserve for high-pressure rinsing. At this time, one end of the connecting test tube 4 is connected to the outlet of the ejection cavity tube 3, and the other end extends into the inside of the packing inclined tube 102 and connects to the liquid pressure head 6 to form a liquid transmission channel. The device enters the cleaning state.

[0027] After the cleaning is initiated, the external force at the spray chamber 3 is removed, the compression spring 32 releases its elastic potential energy, and drives the air compressor rod 33 to rebound in the opposite direction, continuously applying thrust to the liquid inside the chamber. The high-pressure liquid enters the connecting test tube 4 through the chamber outlet to deliver the liquid in a directional manner, avoiding pressure loss and leakage, and ensuring that the high-pressure liquid is completely delivered to the inner wall area of ​​the packing inclined tube 102. On the one hand, the end of the connecting test tube 4 extending into the inside of the inclined tube, through cooperation with the supply connector 93, realizes the liquid diversion. Part of the liquid is directly sprayed onto the inner wall of the inclined tube, precisely impacting local stubborn deposits. The other part of the liquid is delivered to the water distributor 8. Because the water distributor 8 is adapted to the inner arc surface of the packing inclined tube 102, it converts the liquid into a uniform water flow, thoroughly rinsing the inner wall of the inclined tube. On the other hand, in the treatment chamber 101 of the high-efficiency sedimentation tank 1, the scraper blade 52 rotates with the connecting shaft 5, and its bent scraper end 521 closely adheres to the inner wall of the packing inclined tube 102 to remove hardened deposits. The two cleaning actions are carried out simultaneously around the inclined tube target defined by the high-efficiency sedimentation tank 1.

[0028] like Figure 4 and Figure 5As shown, a micro motor module is sleeved on the inner arc surface of the connecting shaft 5. The scraper blade 52 has a bent scraper end 521 at the end away from the connecting shaft 5. One end of the connecting test tube 4 extends into the interior of the packing inclined tube 102. The liquid-pressing head 6 includes a liquid-suction cone 61, one end of which is installed in the inner arc surface of the connecting shaft 5. The filter kit 62 is fixedly installed on the upper surface of the liquid-suction cone 61. The surface of the filter kit 62 has several slots. The outer arc surface of the liquid-pressing head 6 has a retaining groove 601. The inner arc surface of 601 is sleeved onto the upper end face of the connecting block 51. The upper surface of the liquid pressure head 6 is sleeved with a supply connector 93. The upper surface of the supply connector 93 is provided with a supply nozzle in the middle. The inner arc surface of the supply connector 93 is sleeved onto the connecting test tube 4. The filter kit 62 and the water distributor 8 are in the same plane. The outer arc surface of the water distributor 8 is clamped with a cloth holder 801. The cloth holder 801 is sleeved onto the inside of the fixing ring 7. The bent scraper end 521 is attached to the inner arc surface of the packing inclined tube 102.

[0029] The connecting shaft 5 is entirely placed inside the treatment chamber 101 of the high-efficiency sedimentation tank 1. Connecting blocks 51 arranged in a ring array on its outer arc surface provide a fixed carrier for the scraper blade 52. The scraper blade 52 is fixed to the connecting block 51 via one end face, forming a rigid transmission chain. Simultaneously, the bent scraping end 521 of the scraper blade 52 is pre-fitted to the inner arc surface of the packing inclined tube 102. The micro-motor module on the inner arc surface of the connecting shaft 5 is in standby mode, both calibrating the position of the scraping component and storing subsequent power to ensure that the mechanical scraping action can accurately act on the inner wall of the inclined tube and the pressure head 6. The end face is connected to the other end of the connecting test tube 4. The outer arc surface groove 601 is sleeved on the upper end face of the connecting block 51, so that the liquid pressure head 6 and the connecting shaft 5 form a follow-up relationship. When the connecting shaft 5 rotates, the liquid pressure head 6 can move synchronously to avoid the liquid delivery path deviation. At the same time, the liquid suction cone 61 at the bottom of the liquid pressure head 6 is installed into the inner arc surface of the connecting shaft 5. The filter kit 62 on the upper surface of the liquid suction cone 61 is kept horizontal and is on the same plane as the subsequent water distributor 8. This not only reserves a channel for liquid filtration, but also ensures the uniformity of subsequent water distribution, thus completing the positioning and functional preparation of the liquid treatment component.

[0030] After the cleaning process is started, the micro motor on the inner arc surface of the connecting shaft 5 is powered on, causing the connecting shaft 5 to rotate at a constant speed around the axis. The connecting shaft 5 transmits power to the scraper blade 52 through the connecting block 51, causing the scraper blade 52 to move in a circular motion with the connecting shaft 5. The bent scraper end 521 slides against the inner arc surface of the packing inclined tube 102, physically scraping away stubborn deposits at different heights and circumferential positions. The annular array of connecting blocks 51 and scraper blades 52, combined with the length of the connecting shaft 5 that penetrates the treatment chamber 101, completely cover the inner wall of the inclined tube, solving the problem of dead corners in traditional cleaning.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
