Description

Technical Field

[0001] This utility model relates to the field of petrochemicals, specifically a pipeline vacuum cleaning device. Background Technology

[0002] Pipeline vacuum cleaning technology in the petrochemical industry is an efficient and environmentally friendly cleaning method. It is mainly used to remove accumulated ash, impurities and volatiles in pipelines, ensuring the stable operation of the production system. By using a vacuum pump or negative pressure system, the pollutants in the pipeline are sucked to external treatment equipment, avoiding the use of chemical substances and reducing damage to the environment and equipment. Combined with a mechanical scraping device, the ash-scraping part directly removes the deposits on the pipe wall in a vacuum environment, achieving non-stop operation.

[0003] Existing dust removal devices are inconvenient to adjust the position of the dust removal scraper, and the scraper is installed and removed via a tie rod nut, which is inconvenient for quick assembly and disassembly.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the above-mentioned technical defects and provide a pipeline vacuum cleaning device for cleaning vacuum pipelines. It can not only expand the cleaning range, but also facilitate the disassembly and replacement of the cleaning brush.

[0006] To solve the above problems, the technical solution of this utility model is as follows: a pipeline vacuum cleaning device, including a flange, a rotating shaft, and a cleaning brush, wherein a reducer is fixedly connected to the upper end of the flange, a motor is fixedly connected to one end of the reducer, a rotating shaft is rotatably provided inside the flange, and the motor drives the rotating shaft to rotate through the reducer, and further includes: A sleeve is fixedly connected to the lower end of a flange, and a connecting cylinder is slidably connected inside the sleeve. The lower end of the connecting cylinder is fixedly connected to the upper end of a rotating shaft. The housing is fixedly connected to the lower end of the rotating shaft. A cavity is opened inside the housing. There are two cleaning brushes symmetrical about the housing. Two sets of insert rods are provided on one end of the cleaning brush near the housing. The insert rods are inserted into the inside of the housing.

[0007] Preferably, a connecting plate is fixedly connected to the lower end of the rotating shaft, the connecting cylinder is slidably sleeved on the outside of the connecting plate, an inclined annular track is provided on the inner wall of the sleeve, and a slider is provided at one end of the connecting cylinder, the slider being slidably connected to the inside of the annular track.

[0008] Preferably, the connecting plate is a cuboid.

[0009] Preferably, both ends of the housing are provided with slidably connected pull rods. One end of the pull rod inside the housing is provided with a conical block. The conical block is provided with pressing blocks on both sides. The other end of the pressing block is provided with a sliding rod. The other end of the sliding rod is inserted into a plug rod. A spring is sleeved on the pull rod. The spring is located between the housing and the conical block.

[0010] Preferably, the extrusion block has a groove matching the curved surface of the conical block at one end near the conical block, a T-shaped rod is fixedly provided at one end inside the housing, a slider two is slidably sleeved on the surface of the T-shaped rod, a short rod is fixedly connected to one end of the slider two, a sliding rod is fixedly connected to the other end of the short rod, a support frame is provided inside the housing, and the sliding rod passes through the support frame.

[0011] Preferably, a spring is fitted onto the surface of the T-shaped rod, and the spring is located between the slider and the support frame.

[0012] The advantages of this invention compared to existing technologies are as follows: (1) When this utility model is used, the flange is installed with the pipe to be cleaned. The motor drives the rotating shaft to rotate through the reducer, which in turn drives the connecting plate to rotate. The rotating connecting plate drives the connecting cylinder to rotate. The slider slides inside the ring track, so that the connecting cylinder can move up and down while rotating. The movement of the connecting cylinder drives the rotating shaft to move, which in turn drives the cleaning brush to move through the housing and the plug rod. The two sets of cleaning brushes move by rotating on the inner wall of the pipe and moving up and down, thereby increasing the range of cleaning the inner wall of the pipe. (2) When the plug rod needs to be disassembled to replace the cleaning brush, when the plug rod needs to be disassembled, the pull rod is pulled to move the cone block. Once the spring is compressed, the squeezing block is no longer squeezed by the cone block. The spring recovers and drives the slider to slide on the surface of the T-shaped rod, thereby driving the sliding rod to slide, so that one end of the sliding rod is separated from the plug rod and drives the squeezing block to approach the cone block. At this time, the plug rod and the cleaning brush can be disassembled. Attached Figure Description

[0019] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals.

[0020] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0021] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0022] like Figure 1-5 As shown, a pipeline vacuum cleaning device includes a flange 1, a rotating shaft 5, and a cleaning brush 6. A reducer 3 is fixedly connected to the upper end of the flange 1, and a motor 4 is fixedly connected to one end of the reducer 3. The motor 4 is fixed by a motor mounting base. A rotating shaft 7 is rotatably installed inside the flange 1. The rotating shaft 7 and the flange 1 are sealed by magnetic fluid sealing technology. The motor 4 drives the rotating shaft 7 to rotate through the reducer 3. The flange 1 can be connected to the pipeline that needs to be cleaned. A fluororubber sealing ring is provided at the flange connection to ensure the vacuum inside the pipeline. The motor 4 is time-controlled by PLC programming. The PLC program defines start and stop buttons and combines them with a timer to realize delayed operation. The motor 4 can be started and stopped as needed.

[0023] Sleeve 8 is fixedly installed at the lower end of flange 1. Connecting cylinder 9 is slidably installed inside sleeve 8. The lower end of connecting cylinder 9 is fixedly connected to the upper end of rotating shaft 5. The lower end of rotating shaft 7 is fixedly connected to connecting plate 2. Connecting cylinder 9 is slidably sleeved on the outside of connecting plate 2. Motor 4 drives rotating shaft 7 to rotate through reducer 3, which in turn drives connecting plate 2 to rotate. Connecting plate 2 is cuboid. A cuboid groove matching connecting plate 2 is opened inside connecting cylinder 9, so that connecting cylinder 9 can rotate when connecting plate 2 rotates. Connecting cylinder 9 can slide on the surface of connecting plate 2. An inclined annular track 10 is opened on the inner wall of sleeve 8. A slider 11 is installed at one end of connecting cylinder 9. Slider 11 is slidably connected to the inside of annular track 10.

[0024] Specifically, when the connecting cylinder 9 rotates, the slider 11 slides downward inside the annular track 10, thereby causing the connecting cylinder 9 to move downward and rotate. When the slider 11 moves to the lowest point of the annular track 10, the connecting cylinder 9 continues to rotate, the slider 11 slides upward, and the connecting cylinder 9 also moves upward. The movement of the connecting cylinder 9 drives the rotating shaft 5 to move, which in turn drives the cleaning brush 6 to move through the housing 12 and the insert rod 13. The two sets of cleaning brushes 6 move by rotating on the inner wall of the pipe and moving up and down, thereby cleaning the inner wall of the pipe.

[0025] A housing 12 is fixedly installed at the lower end of the rotating shaft 5. A cavity is opened inside the housing 12. There are two cleaning brushes 6 symmetrically about the housing 12. Two sets of insert rods 13 are installed at the end of the cleaning brushes 6 near the housing 12. The insert rods 13 are inserted into the inside of the housing 12. One end of the insert rod 13 has a groove that matches the sliding rod 17. Both ends of the housing 12 are equipped with slidingly connected pull rods 14. A conical block 15 is installed at the end of the pull rod 14 inside the housing 12. A spring is sleeved on the pull rod 14. The spring is located between the housing 12 and the conical block 15.

[0026] The conical block 15 has pressing blocks 16 on both sides. The pressing block 16 near the end of the conical block 15 has a groove that matches the curved surface of the conical block 15. When the pull rod 14 is not pulled, the elastic force of the spring causes the conical block 15 to move and the conical block 15 to press the pressing blocks 16 to both ends. A sliding rod 17 is installed at one end of the pressing block 16. Since the support frame 23 is installed inside the housing 12 and the sliding rod 17 passes through the support frame 23, when the pressing block 16 is pressed by the conical block 15, it will drive the sliding rod 17 to slide inside the support frame 23. This allows the other end of the sliding rod 17 to be inserted into the insertion rod 13, thereby fixing the insertion rod 13 and completing the fixed installation of the cleaning brush 6.

[0027] A T-shaped rod 20 is fixedly installed at one end inside the housing 12. A slider 19 is slidably mounted on the surface of the T-shaped rod 20. A short rod 18 is fixedly connected to one end of the slider 19, and the other end of the short rod 18 is fixedly connected to the sliding rod 17. A spring 22 is mounted on the surface of the T-shaped rod 20. The spring 22 is located between the slider 19 and the support frame 23. When the sliding rod 17 moves, the slider 19 is driven by the short rod 18 to compress the spring 22. When the insert rod 13 needs to be disassembled, the pull rod 14 is pulled, which drives the conical block 15 to move. The spring is compressed. At this time, the extrusion block 16 is no longer squeezed by the conical block 15. The spring 22 recovers and drives the slider 19 to slide on the surface of the T-shaped rod 20, thereby driving the sliding rod 17 to slide. This causes one end of the sliding rod 17 to disengage from the insert rod 13 and drives the extrusion block 16 to approach the conical block 15.

[0028] In practical use, flange 1 is installed on the pipe to be cleaned. Motor 4 drives shaft 7 to rotate through reducer 3, which in turn drives connecting plate 2 to rotate. The rotation of connecting plate 2 drives connecting cylinder 9 to rotate. Slider 11 slides inside the annular track 10, allowing connecting cylinder 9 to move up and down while rotating. The movement of connecting cylinder 9 drives rotating shaft 5 to move, which in turn drives cleaning brush 6 through housing 12 and insert rod 13. The two sets of cleaning brushes 6 rotate and move up and down on the inner wall of the pipe, thus cleaning the inner wall of the pipe. When insert rod 13 needs to be removed to replace cleaning brush 6, pull rod 14, which drives cone block 15 to move. Spring 1 is compressed, and squeezing block 16 is no longer squeezed by cone block 15. Spring 22 returns to its original state, driving slider 2 19 to slide on the surface of T-shaped rod 20, which in turn drives sliding rod 17 to slide. One end of sliding rod 17 is separated from insert rod 13, and squeezing block 16 is brought closer to cone block 15. At this time, insert rod 13 and cleaning brush 6 can be removed.
