Description

Technical Field

[0001] This utility model belongs to the field of pipeline anti-clogging and relates to a pipeline anti-clogging mechanism for coal coking wastewater treatment. Background Technology

[0002] Coal coking wastewater contains a large amount of tar, coal powder and some crystalline substances. When it is discharged through pipes, these mixtures will accumulate inside the pipes and adhere to the inner wall, causing blockages. In this case, anti-blocking mechanisms are needed to unclog the pipes to ensure the subsequent sewage discharge effect. For example, patent (CN218923995U) discloses a pipe anti-clogging mechanism for sewage treatment equipment, which describes "sewage treatment equipment body, inlet pipe and anti-clogging cover, the inlet pipe is connected to the top of the sewage treatment equipment body, and the anti-clogging cover is inserted inside the inlet pipe, the outer wall of the anti-clogging cover is connected to a reinforcing ring, and clamping mechanisms are provided on both sides of the anti-clogging cover; the clamping mechanism includes a connecting block, a sliding groove, a first spring, a limiting plate, a connecting strip, a slider and a groove, the connecting block is connected to both sides of the anti-clogging cover, and a sliding groove is opened on the outer side of the connecting block, and the first spring is provided inside the sliding groove. The pipe anti-clogging mechanism of this sewage treatment equipment, through the limiting plate that can automatically reset, facilitates the limiting installation of the pipe anti-clogging mechanism, through the upward-pulling blade, facilitates the cleaning of the inside of the pipe anti-clogging mechanism, and through the setting of the rubber protective sleeve, makes the pipe anti-clogging mechanism have a protective structure."

[0003] The existing technology has the following technical defects: Existing anti-clogging mechanisms are usually fixedly installed in pipelines. However, tar solidifies at room temperature and adheres to the entire inner wall of the pipeline. This makes it impossible for the anti-clogging mechanism to clean the accumulated material in different locations on the inner wall of the pipeline, resulting in blockages in other parts of the pipeline. Furthermore, due to the adhesive properties of tar, it is difficult to clean after solidification. After prolonged operation, a large amount of tar mixed with solidified material will inevitably adhere to the surface of the structural components of the anti-clogging mechanism, reducing its cleaning effect or even causing it to lose its anti-clogging effect. Summary of the Invention

[0004] The technical problem this invention aims to solve is that existing anti-clogging mechanisms are typically fixedly installed in pipelines. Tar solidifies at room temperature and adheres to the entire inner wall of the pipeline, making it impossible for the anti-clogging mechanism to clean the accumulated material at different locations on the inner wall. This results in blockages still occurring in other parts of the pipeline. Furthermore, due to the adhesive properties of tar, cleaning it after solidification is difficult. After prolonged operation, a large amount of tar-solidified material inevitably adheres to the surface of the anti-clogging mechanism's structural components, reducing its cleaning effectiveness or even rendering it ineffective. To overcome the shortcomings of existing technologies, this invention provides a pipeline anti-clogging mechanism for coal coking wastewater treatment. This utility model includes a structural cylinder, with a first fixed plate installed at one end and a second fixed plate installed at the other end. A dredging assembly is installed on the structural cylinder, and the dredging assembly includes a movable cavity. The movable cavity is formed inside the structural cylinder, and a reciprocating screw is rotatably installed at an eccentric position inside the movable cavity. A limit rod is fixedly connected inside the movable cavity near the reciprocating screw. A movable seat is sleeved on the outside of the cross-section of the reciprocating screw and the limit rod. A rotating shaft is rotatably installed at the center of the vertical surface of the movable seat. One end of the rotating shaft passes through the structural cylinder and the first fixed plate and extends outward, and is equipped with a spiral cutting blade. Multiple connecting rods are fixedly connected to the end of the rotating shaft near the spiral cutting blade. A fixing groove is formed at the end of the connecting rod, and a scraper is fixedly installed in the fixing groove by bolts. Auxiliary components are installed on the first and second fixed plates.

[0005] Preferably, the movable seat has a structural cavity inside. The end of the rotating shaft near the movable seat is inserted into the structural cavity and a first bevel gear is installed thereon. A rotating rod is rotatably installed inside the structural cavity below the first bevel gear. A second bevel gear is fixedly sleeved on the rotating rod and meshes with the first bevel gear. A connecting gear is fixedly sleeved on the outer side of the section of the rotating rod near the limiting rod. A structural groove is opened at the top of the limiting rod, and multiple gear teeth are fixedly connected at equal intervals inside the structural groove. The connecting gear meshes with the gear teeth. A drive motor is installed on the vertical surface of the second fixed plate away from the structural cylinder. The output shaft of the drive motor is connected to one end of the reciprocating lead screw.

[0006] Preferably, the auxiliary component includes a telescopic cavity. Multiple telescopic cavities are formed on the arc surfaces of the first and second fixed disks. A limit spring is connected to the inner end face of the telescopic cavity. A support block is provided inside each telescopic cavity. The other end of the limit spring is connected to the support block. A rotating wheel is installed on the body of the support block.

[0007] Preferably, each of the support blocks in the second fixed plate is equipped with a small motor, and the small motor acts on the rotating wheel at the corresponding position.

[0008] Preferably, a symmetrically formed closing groove is provided on the outer arc surface of the second fixed plate, and an installation groove is provided on the arc surface inside the closing groove. An electric push rod is installed inside the installation groove, and the pushing end of the electric push rod is connected to a supporting arc plate.

[0009] Preferably, the auxiliary component further includes a heating chamber, a heating chamber is provided inside the first fixed disk near the spiral cutting blade, a heating plate is installed on the inner wall of the heating chamber, a plurality of air blowing holes are provided on the vertical surface of the first fixed disk near the spiral cutting blade, a filter hole is provided on the vertical surface of the first fixed disk near the structural cylinder, and an air pump is installed inside the first fixed disk near the filter hole.

[0010] Working process or working principle: By coordinating the unblocking components and auxiliary components, before cleaning the pipe, a small motor on the support block can be started to rotate the wheel, transporting the spiral cutting blades and scraper to the blockage location. After the spiral cutting blades and scraper reach the designated position, the electric actuator is activated, pushing the support arc plate outward so that the support arc plate rests on the inner wall of the pipe. Subsequently, the air pump operates, drawing outside air into the heating chamber through the filter holes. The heating plate inside the heating chamber heats the incoming air, which is then blown through the air vents onto the tar-solidified mixture, softening the mixture, reducing the adhesion of the accumulated solidified material, and facilitating the scraper. The process involves rapid cleaning; subsequently, the drive motor on the second fixed plate is activated. The drive motor rotates the reciprocating screw, and with the assistance of the limit rod, the moving seat moves the rotating shaft, spiral cutting blade, connecting rod, and scraper along the axis of the rotating shaft. Simultaneously, the connecting gear rotates along its teeth, and the rotating rod drives the second bevel gear to rotate. With the assistance of the first bevel gear, the rotating shaft drives the spiral cutting blade and scraper to rotate, effectively cleaning different locations on the inner wall of the pipe. As the reciprocating screw rotates continuously, the moving seat drives the rotating shaft and scraper to move back and forth over short distances, achieving back-and-forth cleaning of the inner wall of the pipe within a short distance, ensuring the cleaning effect.

[0011] Compared with the prior art, the beneficial effects of this utility model are: By using the dredging components in conjunction with other equipment, the accumulated material adhering to the inner wall of the pipe can be scraped off, achieving back-and-forth cleaning of the inner wall of the pipe over a short distance, ensuring cleaning effectiveness and preventing omissions.

[0012] With the cooperation of auxiliary components, the pipe can be thoroughly cleaned in different locations, and the solidified tar mixture can be softened during the cleaning process to reduce the adhesion of the accumulated solidified material and facilitate the rapid cleaning by the scraper.

Detailed Implementation

[0015] Example 1 like Figures 1-5As shown, a pipe anti-clogging mechanism for coal coking wastewater treatment includes a structural cylinder 1. A first fixed plate 2 is installed at one end of the structural cylinder 1, and a second fixed plate 3 is installed at the other end of the structural cylinder 1. A dredging component is installed on the structural cylinder 1, and the dredging component includes a moving cavity 4. The moving cavity 4 is opened inside the structural cylinder 1. A reciprocating screw 5 is rotatably installed at an eccentric position inside the moving cavity 4. A limit rod 6 is fixedly connected to the moving cavity 4 near the position of the reciprocating screw 5. A moving seat 7 is sleeved on the outside of the cross section of the reciprocating screw 5 and the limit rod 6. A rotating shaft 8 is rotatably installed at the center position of the vertical surface of the moving seat 7. One end of the rotating shaft 8 passes through the structural cylinder 1 and the first fixed plate 2 and extends to the outside, and a spiral cutting blade 9 is installed thereon. Multiple connecting rods 10 are fixedly connected to the end of the rotating shaft 8 near the position of the spiral cutting blade 9. A fixing groove is opened at the end of the connecting rod 10, and a scraper 11 is fixedly installed in the fixing groove by bolts. Auxiliary components are installed on the first fixed plate 2 and the second fixed plate 3. The first fixed plate 2 and the second fixed plate 3 have the same cross-sectional radius. The central axes of the structural cylinder 1, the first fixed plate 2, the second fixed plate 3, the movable seat 7, and the rotating shaft 8 coincide. The movable seat 7 drives the rotating shaft 8 to move back and forth along the reciprocating screw 5. The spiral cutting blade 9 and the scraper 11 follow the rotating shaft 8 to move back and forth, realizing the back and forth cleaning of the inner wall of the pipe within a short distance, ensuring the cleaning effect.

[0016] The movable seat 7 has a structural cavity 12 inside. The end of the rotating shaft 8 near the movable seat 7 is inserted into the structural cavity 12 and a first bevel gear 13 is installed. Inside the structural cavity 12, below the first bevel gear 13, a rotating rod 14 is rotatably installed. A second bevel gear is fixedly sleeved on the body of the rotating rod 14 and meshes with the first bevel gear 13. A connecting gear 15 is fixedly sleeved on the outside of the section of the rotating rod 14 near the limiting rod 6. A structural groove is opened at the top of the limiting rod 6, and multiple gear teeth 16 are fixedly connected at equal intervals inside the structural groove. The connecting gear 15 meshes with the gear teeth 16. A drive motor 17 is installed on the vertical surface of the second fixed plate 3 away from the structural cylinder 1. The output shaft of the drive motor 17 is connected to one end of the reciprocating screw 5. When the movable seat 7 moves along the limiting rod 6, the connecting gear 15 rotates along the gear teeth 16, causing the rotating rod 14 to drive the second bevel gear to rotate accordingly. With the cooperation of the first bevel gear 13, the rotating shaft 8 drives the spiral cutting blade 9 and the scraper 11 to make circular motion. The spiral cutting blade 9 can crush and clean the blockage in the middle of the pipe, while the scraper 11 can scrape off the solidified material on the inner wall of the pipe. The drive motor 17 provides the driving force for the movement of the movable seat 7 and the rotation of the spiral cutting blade 9 and the scraper 11.

[0017] During operation, thanks to the structural design of the unblocking components, when unblocking the inner wall of the pipe, the drive motor 17 on the second fixed plate 3 can be activated. The drive motor 17 drives the reciprocating screw 5 to rotate. With the cooperation of the limit rod 6, the moving seat 7 drives the rotating shaft 8, the spiral cutting blade 9, the connecting rod 10, and the scraper 11 to move along the axis of the rotating shaft 8. At the same time, the connecting gear 15 rotates along the gear teeth 16, and the rotating rod 14 drives the second bevel gear to rotate. With the cooperation of the first bevel gear 13, the rotating shaft 8 drives the spiral cutting blade 9 and the scraper 11 to rotate, achieving effective cleaning of different positions on the inner wall of the pipe. As the reciprocating screw 5 rotates continuously, the moving seat 7 drives the rotating shaft 8 and the scraper 11 to move back and forth over a short distance, achieving back-and-forth cleaning of the inner wall of the pipe within a short distance, ensuring the cleaning effect and preventing omissions.

[0018] Example 2 like Figures 1-2 , Figures 5-6 As shown, the auxiliary assembly includes telescopic cavities 18. Multiple telescopic cavities 18 are formed on the arc surfaces of both the first fixed plate 2 and the second fixed plate 3. Limiting springs 19 are connected to the inner end faces of the telescopic cavities 18. Each telescopic cavity 18 contains a support block 20. The other end of the limiting spring 19 is connected to the support block 20. Rotating wheels 21 are mounted on the support blocks 20. When the limiting spring 19 is not in operation, it does not deform. At this time, the rotating wheel 21 is furthest from the center of the first fixed plate 2, and the distance between the rotating wheel 21 and the central axis of the first fixed plate 2 is greater than the rotation radius of the scraper 11. When the first fixed plate 2 and the second fixed plate 3 move within the pipe via the rotating wheels 21, the support block 20 experiences a force pushing into the telescopic cavity 18. The limiting spring 19 is compressed and generates a reaction force. This reaction force causes the limiting spring 19 to tend to return to its original position, ensuring that the rotating wheel 21 is pressed tightly against the inner wall of the pipe, allowing the first fixed plate 2 and the second fixed plate 3 to move smoothly on the rugged inner wall of the pipe.

[0019] Each of the support blocks 20 in the second fixed disk 3 is equipped with a small motor 22, which acts on the rotating wheel 21 at the corresponding position. This provides the driving force for the movement of the entire device. With the cooperation of multiple rotating wheels 21, it is possible to ensure that the spiral cutting blade 9 and the scraper 11 are moved to the designated position.

[0020] The second fixed plate 3 has symmetrically formed closing grooves 23 on its outer arc surface. An installation groove is formed on the arc surface inside the closing groove 23, and an electric actuator 24 is installed inside the installation groove. The pushing end of the electric actuator 24 is connected to a supporting arc plate 25. When the scraper 11 and the spiral cutting blade 9 rotate, the electric actuator 24 can be activated to push the supporting arc plate 25 against the inner wall of the pipe, thus achieving a stable supporting effect and ensuring the stable operation of the entire device in the anti-clogging position.

[0021] The auxiliary components also include a heating chamber 26. The heating chamber 26 is located inside the first fixed plate 2 near the spiral cutting blade 9. A heating plate is installed on the inner wall of the heating chamber 26. Multiple air blowing holes 27 are located on the vertical surface of the first fixed plate 2 near the spiral cutting blade 9. A filter hole 28 is located on the vertical surface of the first fixed plate 2 near the structural cylinder 1. An air pump is installed inside the first fixed plate 2 near the filter hole 28. The heating plate on the inner wall of the heating chamber 26 heats the air drawn in by the air pump. A filter screen is installed in the filter hole 28. Since the working environment of the second fixed plate 3 is located inside the sewage pipe, the air is relatively polluted. The filter screen in the filter hole 28 filters the drawn-in air. The hot air blown out by the air blowing holes 27 not only acts on the tar solidified material but also on the rotating scraper 11 and spiral cutting blade 9, preventing the softened tar solidified material from accumulating and adhering on the spiral cutting blade 9 or scraper 11.

[0022] During operation, thanks to the structural design of the auxiliary components, before cleaning the pipe, the small motor 22 on the support block 20 can be started to rotate the wheel 21, thus transporting the spiral cutting blade 9 and scraper 11 to the blockage location, achieving cleaning and unblocking of different locations on the inner wall of the pipe. After the spiral cutting blade 9 and scraper 11 reach the designated position, the electric push rod 24 is activated, which pushes the support arc plate 25 outward, so that the support arc plate 25 is supported on the inner wall of the pipe. Then, the air pump operates, drawing external air into the interior of the heating chamber 26 through the filter hole 28. The heating plate inside the heating chamber 26 operates, heating the incoming air and blowing it through the air blowing hole 27 onto the tar solidified mixture, achieving the effect of softening the mixture, reducing the adhesion of the accumulated solidified material, and facilitating the rapid cleaning by the scraper 11.
