Abstract
Description
Technical Field
[0001] This utility model belongs to the field of pipeline dredging technology, and in particular relates to a component for dredging waste gas pipelines. Background Technology
[0002] Exhaust gas pipelines play a crucial role in industries such as chemical engineering, primarily used for collecting, transporting, and treating waste gases generated during industrial production. The proper functioning of these pipeline systems is essential for ensuring production efficiency and environmental protection. Over time, high concentrations of adhesive substances, such as grease, dirt, and deposits, may accumulate inside the pipelines. These substances not only reduce the pipeline's transport efficiency but can also cause corrosion and blockages, thereby affecting the normal operation of production equipment and the effective treatment of waste gases.
[0003] Most exhaust duct cleaning kits have several drawbacks, such as being only effective for pipes of a fixed size. For pipes of different diameters, different kits may be required, increasing operational complexity and cost. Furthermore, wire brushes need replacement after prolonged use, requiring manual tools, which is inconvenient when tools are unavailable. Therefore, we propose an exhaust duct cleaning kit. Utility Model Content
[0004] The purpose of this invention is to provide a component for unblocking waste gas pipelines to solve the problems mentioned in the background art.
[0005] In view of this, the present invention provides a component for unblocking exhaust gas pipes, including a cylinder, a motor, and a disc, and further comprising:
[0006] The power chamber is located inside the disc, the motor is fixedly installed inside the cylinder, the disc is rotatably installed at the top of the cylinder, and the output shaft of the motor passes through the cylinder and is fixedly connected to the disc.
[0007] A plurality of sliding columns are slidably installed in the power cavity. The ends of the plurality of sliding columns that are far apart from each other all penetrate the power cavity and are fixedly installed with fixing strips. A fixing plate is provided on one side of each of the plurality of fixing strips. A wire brush is fixedly installed on each of the plurality of fixing plates.
[0008] A driving component, located inside the disk, is used to drive a plurality of sliding columns to slide.
[0009] A plurality of fixing components are located within a plurality of fixing strips and are used to fix the positions of a plurality of fixing plates.
[0010] In this technical solution, when it is necessary to unclog the exhaust gas pipeline, the set drive component can drive several sliding columns to slide and move away from each other. The several sliding columns drive several fixed strips, several fixed plates and several wire brushes to slide. When the wire brushes can all make close contact with the inner wall of the exhaust gas pipeline, the whole device is placed into the exhaust gas pipeline. The set drive component ensures that the wire brushes are all in close contact with the inner wall of the exhaust gas pipeline. Finally, the motor is started. The motor can drive the disc to rotate, and the disc drives the wire brushes to rotate. The wire brushes can clean the inner wall of the exhaust gas pipeline, ensuring that the inner wall of the exhaust gas pipeline can be completely cleaned.
[0011] When the wire brush needs to be replaced after long-term use, the user can pull out the fixing plate using the set fixing components, and then place the new fixing plate on one side of the fixing strip. The fixing components can fix the position of the fixing plate, making it easy to fix the new wire brush. The operation is simple and convenient and does not require the use of tools.
[0012] In the above technical solution, the driving component further includes:
[0013] A first bevel gear is rotatably mounted in the power chamber and located above a plurality of sliding columns. A plurality of second bevel gears are meshed at the bottom of the first bevel gear. A threaded rod is fixedly mounted at the ends of the plurality of second bevel gears that are far apart from each other. The threaded rods are located at one end of the plurality of sliding columns, and the ends of the threaded rods that are far apart from each other extend into the plurality of sliding columns. The threaded rods are threadedly connected to the plurality of sliding columns.
[0014] A ratchet is fixedly mounted on the top of the first bevel gear. A pawl is rotatably mounted inside the power chamber and on one side of the ratchet. One end of the pawl extends between two adjacent teeth of the ratchet. A fixing post is fixedly mounted on the top of the pawl. A torsion spring is sleeved on the fixing post. The two ends of the torsion spring are fixed to the inner wall of the power chamber and the fixing post, respectively.
[0015] In this technical solution, when it is necessary to unclog the exhaust gas pipeline, the fixed column and the pawl are rotated, and the torsion spring is twisted simultaneously. When one end of the pawl is no longer located between two adjacent teeth of the ratchet, the ratchet is rotated in the forward direction, driving the first bevel gear to rotate in the forward direction. The first bevel gear drives several second bevel gears meshing with it to rotate, and the several second bevel gears drive several threaded rods to rotate. Under the action of the threads, several sliding columns slide and move away from each other. The several sliding columns drive several fixed bars, several fixed plates, and several wire brushes to slide away from the first bevel gear. When all the wire brushes are in place... Once the wire brushes are in close contact with the inner wall of the exhaust duct, the entire device is placed inside the exhaust duct. Then, the operator loosens the fixing column. Under the torsional force of the torsion spring, both the fixing column and the pawl rotate. Then, one end of the pawl is reinserted between two adjacent teeth of the ratchet, preventing the ratchet from rotating in the opposite direction. This ensures that all the wire brushes are in close contact with the inner wall of the exhaust duct. Finally, the motor is started. When the motor is powered on, it drives the disc to rotate. The disc drives the wire brushes to rotate, and the wire brushes clean the inner wall of the exhaust duct, ensuring that the inner wall of the exhaust duct is completely cleaned.
[0016] In the above technical solution, the fixing component further includes:
[0017] A sliding groove is formed within a fixed strip. A limiting strip, which is fixed to a fixed plate, is inserted into the sliding groove. A limiting block is slidably installed within the sliding groove. One end of the limiting block extends into the limiting strip and is inserted into the limiting strip. Several springs, which are fixed to the inner wall of the sliding groove, are fixedly installed on the limiting block. One side of the limiting block penetrates the sliding groove and extends to the outside.
[0018] In this technical solution, when the wire brush needs to be replaced after long-term use, firstly, pull the limiting block to slide away from the wire brush. At the same time, several springs are compressed and contracted. When one end of the limiting block disengages from the corresponding limiting strip, the user can pull the fixing plate and remove the limiting strip. Then, the new fixing plate is reinserted into the sliding groove through the limiting strip. Finally, the user releases the limiting block. Under the rebound force of several springs, one end of the limiting block is inserted into the limiting strip, which can fix the position of the limiting strip and facilitate the fixing of the new wire brush. The operation is simple and convenient, and no tools are required.
[0019] In the above technical solution, further, the upper end of the ratchet passes through the power cavity and is fixedly installed with an operating disc, and the upper end of the fixing post passes through the power cavity and is fixedly installed with a handle.
[0020] In this technical solution, the operating panel facilitates the rotation of the ratchet, and the handle facilitates the rotation of the fixed column.
[0021] In the above technical solution, the cross-sectional shape of the limiting strip is trapezoidal.
[0022] In this technical solution, it is ensured that the limiting strip can only move in one direction within the sliding groove, thus guaranteeing a good fixing effect for the limiting strip.
[0023] In the above technical solution, further, the plurality of sliding columns are distributed in a ring at equal intervals within the disk.
[0024] In this technical solution, several wire brushes are used to clean the inner wall of the exhaust gas duct.
[0025] In the above technical solution, the output shaft of the motor is rotatably connected to the cylinder, and several second bevel gears, several threaded rods, ratchet and fixed column are all rotatably connected to the power cavity.
[0026] In this technical solution, the output shaft of the motor can rotate within the cylinder, ensuring that several second bevel gears, several threaded rods, ratchet, and fixed column can all rotate within the power cavity.
[0027] The beneficial effects of this utility model are:
[0028] 1. This exhaust gas duct unblocking component, when needed to unblock an exhaust gas duct, uses a drive assembly to move several sliding columns away from each other. These sliding columns then move several fixed strips, fixed plates, and wire brushes. Once all the wire brushes are in close contact with the inner wall of the exhaust gas duct, the entire device is placed inside the duct. The drive assembly ensures that all the wire brushes are in close contact with the inner wall of the duct. Finally, the motor is started, which drives a disc to rotate. The disc rotates the wire brushes, allowing them to clean the inner wall of the exhaust gas duct, ensuring that the inner wall is completely cleaned.
[0029] 2. When the wire brush of this exhaust duct cleaning component needs to be replaced after long-term use, the user can pull the fixing plate to remove it through the fixed component, and then place the new fixing plate on one side of the fixing strip. The fixed plate can be fixed in position by the fixed component, which makes it easy to fix the new wire brush. The operation is simple and convenient and does not require the use of tools.

[0068] This embodiment provides a waste gas pipeline unblocking component, which, in addition to the technical solutions of the above embodiments, also has the following technical features.
[0069] In this embodiment, the output shaft of the motor 2 is rotatably connected to the cylinder 1, and several second bevel gears 10, several threaded rods 11, ratchet 12 and fixed column 14 are all rotatably connected to the power chamber 4.

[0071] Working principle: When it is necessary to unclog the exhaust pipe, turn the handle 16 to drive the fixed column 14 and the pawl 13 to rotate. At the same time, the torsion spring 15 is twisted. When one end of the pawl 13 is no longer between two adjacent teeth of the ratchet 12, turn the operating disc 17 forward to drive the ratchet 12 and the first bevel gear 9 to rotate forward. The first bevel gear 9 drives several second bevel gears 10 that mesh with it to rotate. The several second bevel gears 10 drive several threaded rods 11 to rotate. Under the action of the threads, several sliding columns 5 slide and move away from each other.

Once all the dry wire brushes 8 are in close contact with the inner wall of the exhaust pipe, the entire device is placed into the exhaust pipe. Then, the user releases the handle 16. Under the torsional force of the torsion spring 15, the fixed column 14, the pawl 13, and the handle 16 all rotate. Then, one end of the pawl 13 is reinserted between two adjacent teeth of the ratchet 12, preventing the ratchet 12 from rotating in the opposite direction. This ensures that all the wire brushes 8 are in close contact with the inner wall of the exhaust pipe. Finally, the motor 2 is started. When the motor 2 is powered on, it drives the disc 3 to rotate. The disc 3 drives the wire brushes 8 to rotate, and the wire brushes 8 can clean the inner wall of the exhaust pipe, ensuring that the inner wall of the exhaust pipe is completely cleaned.
[0072] When the wire brush 8 needs to be replaced after prolonged use, first pull the limiting block 20 to slide away from the wire brush 8. At the same time, several springs 21 are compressed and contracted. After one end of the limiting block 20 is disengaged from the corresponding limiting strip 19, the user can pull the fixing plate 7 and remove the limiting strip 19. Then, the new fixing plate 7 is reinserted into the sliding groove 18 through the limiting strip 19. Finally, the user releases the limiting block 20. Under the rebound force of several springs 21, one end of the limiting block 20 is inserted into the limiting strip 19, which can fix the position of the limiting strip 19 and facilitate the fixing of the new wire brush 8. The operation is simple and convenient and does not require tools.
