Description

Technical Field

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

[0002] In the chemical industry, such as in carbonation towers (core equipment for producing soda ash using the ammonia-soda and combined alkali processes), the pipes are prone to scaling due to the reaction of ammonia brine with carbon dioxide, producing sodium bicarbonate and calcium carbonate. This scaling also accumulates impurities, leading to pipe blockage and increased flow resistance over long-term use. Traditional cleaning methods rely heavily on manual cleaning or single physical / chemical cleaning methods, which suffer from problems such as a narrow range of compatible pipe diameters, incomplete scale removal, susceptibility to secondary blockages, high labor costs, and low efficiency. These methods fail to meet the high-efficiency and stable cleaning requirements of carbonation tower pipes, necessitating a more suitable and efficient specialized cleaning system. Utility Model Content

Through the above device, it is beneficial to stably transmit the power of the left motor to the rotating plate, providing reliable power support for the rotating plate to drive the subsequent scraper to make circular motion, ensuring that the scraper can rotate synchronously with the rotating plate, and laying the power transmission foundation for efficiently scraping the scale on the inner wall of the pipe.

[0007] According to the pipeline cleaning mechanism of this utility model, a right support shell is fixedly connected to the right surface of the main shell, and the right rotating shaft passes through the right surface of the right support shell.

[0020] Reference Figure 1-4 This utility model discloses a pipe cleaning mechanism, comprising: a main body shell 1, an electric telescopic rod 2 embedded inside the main body shell 1, a wheel frame 3 fixedly connected to the extended end of the electric telescopic rod 2, a roller 4 rotatably connected inside the wheel frame 3, a left motor 11 fixedly connected to the left surface of the main body shell 1, a left rotating shaft 12 fixedly connected to the output end of the left motor 11, a left support shell 5 fixedly connected to the left surface of the main body shell 1, the left rotating shaft 12 penetrating through the left surface of the left support shell 5 and covering the left motor 11, a right motor 13 fixedly connected to the right surface of the main body shell 1, and a right rotating shaft 14 fixedly connected to the output end of the right motor 13. A right support shell 6 is fixedly connected to the right surface of the shell 1. A right rotating shaft 14 passes through the right surface of the right support shell 6, and the right support shell 6 covers the right motor 13. A rotating plate 7 is fixedly connected to the side surface of the left rotating shaft 12. An electric telescopic rod 8 is fixedly connected to the left surface of the rotating plate 7. A scraper 9 is fixedly connected to the extended end of the electric telescopic rod 8. The rotating plate 7, the electric telescopic rod 8, and the scraper 9 are located on the left side of the left support shell 5. A connector 15 is fixedly connected to the end of the right rotating shaft 14 away from the right motor 13. A flexible auger 10 is fixedly connected to the side surface of the connector 15. The connector 15 and the flexible auger 10 are located on the right side of the right support shell 6.

[0021] Specifically, the pipeline cleaning mechanism mainly consists of a main structure and a walking system, a left-side cleaning system, and a right-side auxiliary system. In the main structure and walking system, the main shell 1 serves as the core load-bearing frame, integrating internal control mechanisms (such as PLCs and sensors) and externally connecting various functional components (motors, telescopic rods, etc.), providing overall support and protection. The electric telescopic rod 2 adjusts the opening of the wheel frame 3 by extending and retracting, allowing the rollers 4 to adapt to pipes of different diameters and maintain close contact with the inner wall. The power mechanism provides rotational power to the rollers 4 to control the walking speed. The rollers 4 directly contact the inner wall of the pipe, and through the power mechanism (such as a motor-driven rotation), they drive the entire mechanism forward, backward, or turn within the pipe, acting as the execution component of the walking system. In the left-side cleaning system, the left motor 11 drives the left rotating shaft 12 to rotate. The left support shell 5 protects the motor and stabilizes the rotating shaft. The rotating plate 7 rotates with the rotating shaft. The electric telescopic rod 8 adjusts the distance and pressure between the scraper 9 and the pipe wall. The scraper 9 removes scale through rotation. In the right auxiliary system, the right motor 13 drives the right rotating shaft 14 to rotate, the right support shell 6 protects the motor and fixes the rotating shaft, and the connector 15 connects the rotating shaft to the flexible auger 10. The flexible auger 10 rotates to push out scale and debris and assists in cleaning dead corners.

[0022] During operation, the pipe is first adapted. Based on the actual diameter of the carbonization tower pipe, the electric telescopic rod 2 on the main body shell 1 extends or retracts accordingly, causing the wheel frame 3 to open to a suitable range matching the pipe diameter, ensuring the rollers 4 fit tightly against the inner wall of the pipe, laying the foundation for non-slip movement. Next, the movement control is activated. The control mechanism inside the main body shell 1 drives the power mechanism at the connection point of the rollers 4, causing the rollers 4 to rotate, thus driving the entire mechanism forward at a constant speed within the pipe. It can also pause or reverse at any time according to cleaning needs. Then, left-side scraping is performed. The left motor 11 starts and outputs torque, driving the left rotating shaft 12 to rotate. The left rotating shaft 12 drives the rotating plate 7 and the scraper 9 mounted on it to move in a circular motion synchronously. Simultaneously, the electric telescopic rod 8... The contact pressure between the scraper 9 and the pipe wall can be flexibly adjusted according to the pipe diameter or scale thickness, so that the scraper 9 can efficiently scrape off the scale on the inner wall of the pipe at high speed, especially the hard calcium carbonate scale. While scraping on the left side, the right side is discharged. The right motor 13 drives the right rotating shaft 14 to rotate. The right rotating shaft 14 drives the soft auger 10 to rotate through the connector 15. The soft auger 10 uses its spiral structure to continuously push the scale debris such as sodium bicarbonate crystals and impurities scraped off by the scraper 9 on the left side to the outside of the pipe. The length of the soft auger 10 is suitable for the length of the pipe that needs to be cleaned, effectively avoiding secondary blockage caused by debris accumulation.

[0023] Working principle: First, the opening range of the wheel frame 3 is adjusted by the electric telescopic rod 2, so that the roller 4 fits the inner wall of the pipe to match the pipe diameter. The control mechanism inside the main shell 1 drives the power mechanism at the roller 4, causing the mechanism to move at a constant speed inside the pipe, which can be paused or reversed as needed. At the same time, the left motor 11 drives the left rotating shaft 12, which drives the rotating plate 7 and scraper 9 to rotate. The electric telescopic rod 8 adjusts the pressure of the scraper 9 to scrape off the scale. The right motor 13 drives the right rotating shaft 14, which drives the soft auger 10 to rotate through the connector 15, pushing the debris scraped off by the scraper 9 out of the pipe. The left support shell 5 and the right support shell 6 protect the left and right motors respectively. All components work together to achieve pipe cleaning.
