Description

Technical Field

[0001] This utility model relates to the field of pipeline cleaning technology, and in particular to an activated coke conveying pipeline with a cleaning mechanism. Background Technology

[0002] Activated carbon deep adsorption technology is widely used in the deep treatment of industrial wastewater and municipal sewage as a highly efficient water treatment technology. Activated carbon has a large specific surface area and pore volume, exhibiting strong adsorption capacity. It can adsorb and fix organic matter, heavy metal ions, pigments, and other substances in wastewater, thereby achieving the purpose of wastewater purification.

[0003] In wastewater treatment using activated carbon, the activated carbon needs to be premixed with water before being pumped to a wastewater tank via pipeline. The mixture comes into deep contact with the wastewater after stirring, thereby adsorbing large, recalcitrant organic molecules. However, the viscosity of activated carbon increases significantly after wetting, meaning the premixed activated carbon and water solution has a certain viscosity, leading to adhesion to the pipe walls during transport.

[0004] Once the premixed liquid adheres to the pipe walls, and this adhesion worsens with continued flow, it increases pumping resistance and flow velocity, leading to increased transport losses. In this case, pipe cleaning is necessary. Conventional tapping and vibration are ineffective in removing the wet liquid from the pipe walls and may even damage them. Alternatively, the system can be shut down, the pipes disassembled, and high-pressure water flushed to remove the adhered wet liquid, which can then be reused. However, this method is cumbersome, time-consuming, physically demanding for workers, and disrupts normal equipment operation. Summary of the Invention

[0005] To solve the problem of difficult cleaning of pipe walls, this utility model provides an activated coke conveying pipe with a cleaning mechanism. The pipe is designed to be rotatable, and a cleaning cage is fixedly installed inside the pipe. The cleaning cage and the pipe can rotate relative to each other. The cleaning cage is used to scrape off the material stuck to the inner wall of the pipe, thus achieving convenient cleaning of the pipe wall.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An activated coke conveying pipe with a cleaning mechanism includes two end joints, a conveying straight pipe, a cleaning cage, and a rotating assembly. The conveying straight pipe is connected between the two end joints, and a sealing assembly is provided between the end of the conveying straight pipe and the end joint to prevent leakage at the connection point. The cleaning cage is horizontally inserted inside the conveying straight pipe, and the cleaning cage is in contact with the inner wall of the conveying straight pipe, which facilitates the scraping off of the adhering material on the inner wall of the conveying straight pipe. Both ends of the cleaning cage extend out of the conveying straight pipe and are snapped into the inner wall of the end connector, which facilitates the fixing of the cleaning cage. At least one of the rotating components is provided outside the conveying straight pipe. The rotating component includes a stabilizing seat and a rotating wheel. The stabilizing seat is arranged in a circle around the conveying straight pipe and is rotatably connected to the conveying straight pipe. The stabilizing seat extends downward and is fixed to the ground, which helps to improve the stability of the rotation of the conveying straight pipe. The rotating wheel is fixedly sleeved on the outside of the conveying straight pipe to facilitate the rotation of the conveying straight pipe. The rotating wheel is equipped with a hand-tightening bolt, which is inserted into the stabilizing seat to restrict the rotation of the conveying straight pipe.

[0007] Furthermore, the end connector is a short pipe body with a flange at one end for easy flange connection with other pipes. The flange extends radially inward to reduce the inner diameter of the end connector, and a groove is provided on the inner wall of the flange for engaging the cleaning cage.

[0008] Furthermore, the conveying straight pipe includes a straight pipe section and an enlarged section. The two ends of the straight pipe section extend radially outward to form the enlarged section. The diameter of the enlarged section is larger than that of the straight pipe section, which facilitates the matching of end connectors. The enlarged section is fitted onto the end joint, and a rolling bearing is provided between the enlarged section and the end joint. A limiting ring is fitted onto the end joint, and one end of the rolling bearing abuts against the limiting ring to facilitate limiting the position of the rolling bearing. A flat bearing is provided between the end of the enlarged section and the flange, and the flat bearing is fitted onto the limiting ring.

[0009] Furthermore, the sealing assembly includes a sealing ring and a sealing gasket. The sealing ring is disposed between the end of the end connector and the end of the straight pipe section. The sealing gasket is also sleeved outside the end connector. The sealing gasket corresponds to the rolling bearing. A compression spring is sleeved on the end connector between the sealing gasket and the rolling bearing. The compression spring pushes the end face of the sealing gasket to press tightly against the enlarged section. A labyrinth sealing structure is provided between the mating surfaces of the sealing gasket and the enlarged section, which improves the reliability of the seal.

[0010] Furthermore, the cleaning cage includes a plurality of scrapers evenly arranged in a circumferential direction and connecting rings for connecting the scrapers. The length of the scraper is greater than that of the conveying straight pipe, one side of the scraper contacts the inner wall of the conveying straight pipe, and the plurality of scrapers are connected and fixed together by the connecting rings. The number of connecting rings is at least two, which improves the structural strength of the cleaning cage. There are multiple slots, each corresponding to a scraper. The scraper's end extends into a straight conveying pipe that fits into the slot. The slots help restrict the circumferential rotation and axial movement of the cleaning cage.

[0011] Furthermore, the stabilizing seat is a clamp structure, which includes two symmetrically arranged clamp rings. The two clamp rings are bolted together and fixed. The upper part of the clamp ring is a semi-circular arc plate and the lower part is a bent plate. A stiffening plate is provided between the upper and lower parts of the clamp ring to improve the structural strength of the clamp ring itself. After the upper parts of the two clamp rings are connected, they form a circle and surround the outside of the conveying straight pipe. Two rollers are provided at intervals on the upper part of the clamp ring, and the rollers roll along the surface of the conveying straight pipe.

[0012] Furthermore, the rotating wheel and the stabilizing seat are arranged side by side on the left and right. At least two hand-tightening bolts are arranged on the rotating wheel. The hand-tightening bolts are threadedly connected to the rotating wheel. One end of the hand-tightening bolt is inserted into the upper part of the hoop to facilitate the fixing of the conveying straight pipe and restrict its turnover.

[0013] The beneficial effects of this utility model through the above technical solution are: This utility model has a reasonable structural design. A conveying straight pipe is rotatably arranged between two end connectors, and a cleaning cage is inserted inside the conveying straight pipe. The end of the cleaning cage is snapped and fixed to the end connector. Thus, the conveying straight pipe and the cleaning cage can rotate relative to each other. When the conveying straight pipe is manually operated to rotate, the cleaning cage can be used to scrape off the material adhering to the inner wall of the conveying straight pipe, realizing the self-cleaning of the conveying straight pipe.

[0014] To improve the stability of the conveying straight pipe's rotation, this invention includes a stabilizing seat fitted over the pipe. The lower end of the stabilizing seat is fixed to the ground, while the upper end rotates with the conveying straight pipe via rollers. The stabilizing seat supports the conveying straight pipe without affecting its rotation. By fixing a rotating wheel to the outside of the conveying straight pipe, manual operation allows for convenient rotation of the pipe.

[0015] When cleaning is not required, the conveying straight pipe remains fixed and does not rotate. At this time, the hand-tightening bolt on the rotating wheel is inserted into the stabilizing seat, thus restricting the rotation of the conveying straight pipe. When the hand-tightening bolt is pulled out, the conveying straight pipe can rotate freely. A sealing assembly is also provided between the end connector and the conveying straight pipe, and the reliability of the seal is improved by combining various sealing methods.

Detailed Implementation

[0024] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings: like Figures 1-7 As shown, an activated coke conveying pipeline with a cleaning mechanism includes two end connectors 1, a conveying straight pipe 2, a cleaning cage 3, and a rotating assembly. The end connector 1 is a short pipe body, with a flange 101 at one end, facilitating connection between the end connector 1 and other pipelines. The end connector 1 supports the conveying straight pipe 2 and serves as a connection point between other pipelines and the conveying straight pipe 2.

[0025] A straight conveying pipe 2 is connected between the two end connectors 1, which can support the straight conveying pipe 2, making it suspended. Moreover, after the end connector 1 is bolted to other pipe flanges and remains fixed, the straight conveying pipe 2 can rotate relative to the end connector 1.

[0026] The rotating structure of the conveying straight pipe 2 and the end connector 1 is as follows: The conveying straight pipe 2 includes a straight pipe section 21 and an enlarged section 22. The two ends of the straight pipe section 21 extend radially outward to form the enlarged section 22. The diameter of the enlarged section 22 is larger than that of the straight pipe section 21, which means that the cross-section of the end of the conveying straight pipe 2 is convex. Multiple reinforcing plates 4 are provided circumferentially between the enlarged section 22 and the straight pipe section 21. The reinforcing plates 4 are trapezoidal plates, which are used to enhance the structural strength of the end of the conveying straight pipe 2.

[0027] An enlarged section 22 of the conveying straight pipe 2 is fitted onto the end connector 1. There is a gap between the inner diameter of the enlarged section 22 and the outer diameter of the end connector 1, allowing components to be installed within this gap. Specifically, a rolling bearing 5 is installed between the enlarged section 22 and the end connector 1, fitted onto the end connector 1. To restrict the axial movement of the rolling bearing 5, a limiting ring 6 is fitted onto the end connector 1, abutting against the flange 101. One end of the rolling bearing 5 abuts against the limiting ring 6, restricting its movement to one side. Simultaneously, a flat bearing 7 is installed between the end of the enlarged section 22 and the flange 101, fitted onto the limiting ring 6, with a gap between the flat bearing 7 and the rolling bearing 5.

[0028] As a result, the smoothness of the rotation of the conveying straight pipe 2 can be improved by the cooperation of the rolling bearing 5 and the flat bearing 7. Moreover, the rolling bearing 5 can withstand radial force and the flat bearing 7 can withstand axial force, which meets the application conditions of relative rotation between the end joint 1 and the conveying straight pipe 2.

[0029] Since the end connector 1 and the straight conveying pipe 2 are two independent components, there will inevitably be a gap when they are fitted together. In order to seal the gap and prevent the leakage of the medium in the pipeline, a sealing component is installed between the end of the straight conveying pipe 2 and the end connector 1. The sealing component is used to seal the gap and prevent leakage.

[0030] In this embodiment, the sealing assembly includes a sealing ring 81 and a sealing gasket 82. A sealing ring 81 is provided between the end of the end connector 1 and the end of the straight pipe section 21. The sealing ring 81 includes a rubber ring and a steel ring embedded in the rubber ring. The end connector 1 and the straight pipe section 21 squeeze the sealing ring 81 to achieve a one-time seal.

[0031] A sealing gasket 82 is also fitted over the end connector 1. The sealing gasket 82 is a circular ring plate structure, corresponding to the rolling bearing 5, and can slide on the end connector 1. A compression spring is fitted on the end connector 1 between the sealing gasket 82 and the rolling bearing 5. The compression spring includes a large compression spring 91 and a small compression spring 92, which are arranged inside and outside each other. The two ends of the small compression spring 92 are tightly pressed between the inner ring of the rolling bearing 5 and the middle of the sealing gasket 82, while the two ends of the large compression spring 91 are tightly pressed between the outer ring of the rolling bearing 5 and the perimeter of the sealing gasket 82. The compression spring can provide a certain pushing force, which acts on the sealing gasket 82, thereby pushing the end face of the sealing gasket 82 to press tightly against the enlarged section 22, achieving a secondary seal.

[0032] Note that a labyrinth seal structure 10 is provided between the mating surfaces of the sealing gasket 82 and the enlarged section 22. The labyrinth seal structure 10 is existing technology and will not be described in detail here. The labyrinth seal structure 10 ensures reliable secondary sealing. Simultaneously, a sealing ring 11 is fitted between the mating surfaces of the sealing gasket 82 and the end connector 1 to achieve a sliding seal for the sealing gasket 82.

[0033] As described above, the end connector 1 and the end of the conveying straight pipe 2 are rotatably connected by bearings and reliably sealed by a sealing assembly, enabling smooth rotation of the conveying straight pipe 2 and leak-free conveying of the medium. Based on this, a cleaning cage 3 can be used to clean the inside of the conveying straight pipe 2. The cleaning cage 3 is horizontally inserted inside the conveying straight pipe 2, contacting the inner wall of the conveying straight pipe 2. Both ends of the cleaning cage 3 extend out of the conveying straight pipe 2 and engage with the inner wall of the end connector 1. Because the end connector 1 and the cleaning cage 3 are engaged, the cleaning cage 3 remains fixed and does not rotate. Cleaning of the inside of the conveying straight pipe 2 is achieved by rotating the conveying straight pipe 2 relative to the cleaning cage 3.

[0034] Specifically, the cleaning cage 3 includes three circumferentially arranged scrapers 31 and connecting rings 32 for connecting the scrapers 31. The length of the scrapers 31 is greater than the length of the conveying straight pipe 2. One side of the scraper 31 contacts the inner wall of the conveying straight pipe 2. The three scrapers 31 are connected and fixed together by the connecting rings 32. There are at least two connecting rings 32, and the two connecting rings 32 are equidistant from each other along the length of the scraper 31. The three scrapers 31 can divide one connecting ring 32 into three segments. After the three scrapers 31 are connected and fixed together with at least two connecting rings 32, it resembles a steel cage structure.

[0035] When the cleaning cage 3 is fixed, the flange 101 extends radially inward, which reduces the inner diameter of the end joint 1. A groove 12 with a triangular cross-section is provided on the inner wall of the flange 101 to engage the cleaning cage 3. There are three grooves 12 on one flange 101, each corresponding to a scraper 31. The end of the scraper 31 extends out of the conveying straight pipe 2 and into the groove 12. This restricts the entire cleaning cage 3, preventing it from rotating or moving axially, thus fixing the cleaning cage 3 inside the conveying straight pipe 2.

[0036] At least one rotating assembly is installed outside the conveying straight pipe 2. This assembly drives the conveying straight pipe 2 to rotate, ensuring its stable rotation and also fixing and restricting its rotation. The rotating assembly includes a stabilizing seat 13 and a rotating wheel 14. The stabilizing seat 13 is circularly arranged around the conveying straight pipe 2 and is in rolling connection with it. The stabilizing seat 13 extends downwards and is fixed to the ground. The stabilizing seat 13 acts as a support, providing support for the conveying straight pipe 2 after installation on the ground, without affecting its rotation.

[0037] In this embodiment, the stabilizing seat 13 is similar to a clamp structure. The stabilizing seat 13 includes two symmetrically arranged clamp rings 15, which are bolted together and fixed. The upper part of the clamp ring 15 is a semi-circular arc plate 151, and the lower part is a bent plate 152. The arc plate 151 is bent into a "U" shape, and the bent plate 152 is bolted to the ground. A stiffening plate 153 is provided between the upper and lower parts of the clamp ring 15 to increase the structural strength of the clamp ring 15 and ensure reliable support for the conveying straight pipe 2.

[0038] The two hoop rings 15 are connected at the top and form a circle, surrounding the conveying straight pipe 2. Two rollers 16 are spaced apart on the upper part of the hoop rings 15, and the rollers 16 roll along the surface of the conveying straight pipe 2. It can be seen that the entire stabilizing seat 13 is connected to the conveying straight pipe 2 by rolling through four rollers 16, which not only provides stable support for the conveying straight pipe 2, but also does not affect its rotation, and can also improve the stability of rotation.

[0039] The rotating wheel 14 is fixedly sleeved on the outside of the conveying straight pipe 2. The rotating wheel 14 and the stabilizing seat 13 are arranged side by side. The rotating wheel 14 is similar to a handwheel structure. By operating the rotating wheel 14, the entire conveying straight pipe 2 can be rotated. In order to fix the conveying straight pipe 2, hand-tightening bolts 17 are provided on the rotating wheel 14. At least two hand-tightening bolts 17 are arranged on the rotating wheel 14, and the hand-tightening bolts 17 are threadedly connected to the rotating wheel 14. The hand-tightening bolts 17 are inserted into the stabilizing seat 13 to restrict the rotation of the conveying straight pipe 2. That is, one end of the hand-tightening bolt 17 is inserted into the upper part of the hoop 15. The arc plate 151 on the upper part of the hoop 15 has a insertion hole 18. When the hand-tightening bolt 17 is inserted into the insertion hole 18, the rotating wheel 14 and the stabilizing seat 13 can be connected, and the conveying straight pipe 2 can no longer rotate.

[0040] The principle of this invention is as follows: After the activated coke conveying pipe is installed, it is connected between two other pipes, so that the premixed liquid flows between the other pipes and the conveying straight pipe 2. In the initial state, the hand-tightened bolt 17 is inserted into the stabilizing seat 13, thereby restricting the rotation of the conveying straight pipe 2 and ensuring the relative fixation of the conveying straight pipe 2 and the end connector 1, so that the premixed liquid can flow freely through the conveying straight pipe 2.

[0041] After the premixed liquid adheres to the inner wall of the conveying straight pipe 2, the conveying of the premixed liquid can be paused. Then, unscrew the hand-tightening bolt 17 to disconnect it from the stabilizer 13, and manually rotate the conveying straight pipe 2. Since the cleaning cage 3 does not rotate, the liquid adhering to the inner wall of the conveying straight pipe 2 is scraped off by the relative rotation of the conveying straight pipe 2 and the cleaning cage 3. After cleaning, fix the conveying straight pipe 2 and continue the conveying of the premixed liquid. The premixed liquid carries the scraped-off liquid and is conveyed backward for continued use, thus cleaning the inner wall.

[0042] It should be noted that: 1. The cleaning cage 3 is located inside the straight conveying pipe 2. Although it can clean the inner wall of the straight conveying pipe 2, it will inevitably cause premixed liquid to adhere to it. Therefore, during equipment maintenance, the entire pipe can be removed, the cleaning cage 3 can be taken out, and it can be cleaned. 2. If the pipe used to convey the premixed liquid needs to bend, it can be used with elbows or tees as needed. The elbows or tees are only used to connect two adjacent conveying pipes and are not used for cleaning inside. That is, this conveying pipe only has a cleaning function inside the straight pipe.

[0043] 3. If the pipeline used to transport the premixed liquid is long, multiple pipelines can be installed in series to meet usage requirements. The end joints 1 of adjacent pipelines are bolted together and fixed in place. Specifically, existing clamps can be used to hold two adjacent end joints 1, which are then fixed to the ground. The clamps both secure and support the end joints 1. Furthermore, the pipeline used to transport the premixed liquid consists of multiple pipelines, each with its own cleaning function.

[0044] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the patent claims of this utility model should be included within the scope of the patent application of this utility model.
