Description

Technical Field

[0001] This utility model relates to the field of boiler pipe dredging technology, specifically a dredging device for boiler pipes. Background Technology

[0002] During boiler operation, pipes often accumulate dirt and grime. If this dirt and grime is not cleaned for a long time, it can easily cause pipe bursts, affecting work efficiency and the service life of the pipes. Therefore, pipes should be cleaned regularly.

[0003] Referring to patent CN220471654U, a boiler pipe unblocking device is disclosed, belonging to the technical field of boiler pipe unblocking equipment. It includes a boiler pipe body, with a drain pipe inserted inside the body and a drainage hole inside the drain pipe. A steel wire brush is installed on the outside of the drain pipe, and a connecting pipe is connected to the right end of the drain pipe. An impeller is installed on the right end of the connecting pipe, and a water inlet is opened on the right side inside the connecting pipe. A connecting cylinder is provided outside the impeller. This invention, by setting up an impeller, connecting pipe, drain pipe, and steel wire brush, allows cleaning fluid to enter the interior of the connecting cylinder, impacting the impeller and causing it to rotate. This rotation drives the connecting pipe and the drain pipe to rotate, thereby rotating the steel wire brush outside the drain pipe to scrape and clean the inner wall of the boiler pipe body. The drain pipe can be moved manually left and right, and it can also rotate under the drive of the impeller to scrape and clean the inner wall of the boiler pipe body, resulting in a good cleaning effect.

[0004] The aforementioned device for unclogging boiler pipes relies solely on water flow to drive the impeller, which in turn rotates the unclogging pipe and the wire brush to clean the inner wall of the pipe. However, the power output stability of this water-driven impeller rotation method is relatively poor. Furthermore, if some dirt is firmly adhered, the cleaning effect is relatively poor and the cleaning efficiency is relatively low when relying solely on the wire brush and water spray. It is inconvenient to use and has poor practicality. Utility Model Content

[0009] Furthermore, a slide rail is fixedly installed inside the slide groove, and a groove adapted to the slide rail is opened at the bottom of the cleaning brush to limit and guide the cleaning brush.

[0010] Furthermore, the drive wheel is inclined, and the fixed plate is rotatably connected to the connecting plate via a T-shaped connecting ring. A ring groove adapted to the connecting ring is provided on one side of the connecting plate so as to rotatably connect the fixed plate and the connecting plate.

[0011] Furthermore, the cleaning plate is an arc-shaped structure with the cleaning shaft at the same center, the support rod is convex, and several telescopic rods are symmetrically provided on the right end of the connecting cylinder. The telescopic ends of the telescopic rods are rotatably fitted with ball bearings to adjust the device and adapt it to the pipeline.

In this example, the water supply device can use the structure device in the reference patent, or other water supply devices, as long as they can supply water to the water pipe 2; a motor 3 with a waterproof shell is provided inside the connecting cylinder 1, and the output end of the motor 3 is connected to a water inlet plate 4 inside the connecting cylinder 1. A cleaning shaft 5 is provided outside the connecting cylinder 1, and one end of the cleaning shaft 5 is fixedly connected to the water inlet plate 4. The outer wall of the cleaning shaft 5 is symmetrically provided with sliding grooves 20, and cleaning brushes 7 are provided in the sliding grooves 20. In this example, one side of the cleaning brush 7 is provided with several steel wire bristles. The connecting cylinder 1 is provided with a drive mechanism connected to the output end of the motor 3, and the drive mechanism is connected to one end of two cleaning brushes 7. Several cleaning plates 17 are symmetrically provided on the outer side of the cleaning shaft 5 away from the connecting cylinder 1, and several scrapers 18 are provided on the outer wall of the cleaning plates 17. Several cleaning plates 17 are connected to the cleaning shaft 5 through an adjustment component. In this example, the drive mechanism includes a drive wheel 10, which is sleeved on the outside of the output end of the motor 3. A push rod 11 is provided above the drive wheel 10. A rotating wheel 12 is rotatably mounted on both sides of the bottom of one end of the push rod 11. A connecting plate 8 is slidably sleeved on the outside of the end of the cleaning shaft 5 near the connecting cylinder 1. A fixing plate 9 is rotatably connected to the side of the connecting plate 8 away from the connecting cylinder 1, and the fixing plate 9 is sleeved on the outside of the cleaning shaft 5. The inner wall of the fixing plate 9 is fixedly connected to one end of two cleaning brushes 7. A water inlet trough 21 communicating with the water inlet plate 4 is opened at one end of the cleaning shaft 5. Several nozzles 13, connected to the water supply tank 21, are symmetrically positioned on the outer wall of shaft 5. The drive mechanism is linked to the motor 3, continuously driving two cleaning brushes 7 to reciprocate left and right within the slide 20. Simultaneously, the cleaning brushes 7 rotate with the cleaning shaft 5, facilitating better cleaning of the boiler pipe's inner wall. This, combined with water spraying from the nozzles 13 and scraping from the cleaning plate 17 and scraper 18, removes dirt adhering to the pipe's inner wall, enabling multiple cleaning methods and improving the cleaning effect and efficiency of the boiler pipe's inner wall, thus enhancing its practicality. In this example, a slide rail 6 is fixedly installed within the slide 20, and the bottom of the cleaning brush 7 has a groove 22 adapted to the slide rail 6 for limiting and guiding the cleaning brush 7. In this example, the drive wheel 10 is inclined, and the fixed plate 9 is rotatably connected to the connecting plate 8 via a T-shaped connecting ring. A groove adapted to the connecting ring is provided on one side of the connecting plate 8 to rotatably connect the fixed plate 9 to the connecting plate 8.

[0023] In this example, the adjustment assembly includes a telescopic rod 14, which is embedded in the end of the cleaning shaft 5 away from the connecting cylinder 1. A sliding sleeve 15 is symmetrically provided on the outer wall of one end of the cleaning shaft 5. A support rod 16 is slidably installed inside the sliding sleeve 15. The upper end of the support rod 16 is fixedly connected to the inner wall of the cleaning plate 17, and the lower side of the support rod 16 is hinged to the telescopic end of the telescopic rod 14 via a connecting rod 19. The adjustment assembly allows for the adjustment of the positions of multiple cleaning plates 17 as needed, making them suitable for pipes of different diameters and improving their applicability. In this example, the cleaning plate 17 is an arc-shaped structure concentric with the cleaning shaft 5, the support rod 16 is convex, and several telescopic rods 23 are symmetrically provided on the right end of the connecting cylinder 1. A ball bearing 24 is rotatably embedded in the telescopic end of each telescopic rod 23 to adjust the device and adapt it to the pipe.

[0024] The working principle of this utility model is as follows: In use, connect the water pipe 2 to an external water supply device. Then, place the device into the boiler pipe that needs dredging. Adjust the position of the cleaning plate 17 according to the inner diameter of the pipe. Activate the telescopic rod 14, causing its telescopic end to retract and move. This telescopic rod 14 will drive the connecting rod 19 to push the connected support rod 16, which in turn will push the connected cleaning plate 17 until the scraper 18 contacts the inner wall of the pipe. Simultaneously, activate the telescopic rod 23, causing its telescopic end to extend outwards until the ball bearing 24 contacts the inner wall of the pipe, thus supporting the device. Water is then supplied through the water supply device into the connecting cylinder 1, then through the inlet plate 4 into the water delivery tank 21, and finally sprayed out through the nozzle 13. The starting motor 3 drives the water inlet plate 4 and cleaning shaft 5 to rotate, which in turn drives the two cleaning brushes 7, multiple cleaning plates 17, and scrapers 18 to rotate. This allows the scrapers 18 to first scrape the inner wall of the connecting cylinder 1, then the cleaning brushes 7 to be brushed by the wire bristles, and finally the nozzles 13 to spray water for rinsing, achieving multiple cleaning processes. At the same time, the output of the motor 3 drives the drive wheel 10 to rotate, which in turn drives the two rotating wheels 12 to drive the connected push rod 11 to move back and forth. This, in turn, drives the connecting plate 8 and the fixing plate 9, causing the fixing plate 9 to drive the two cleaning brushes 7 connected to it to slide left and right along the slide rail 6. This allows the cleaning brushes 7 to move left and right while rotating with the cleaning shaft 5, improving the cleaning effect on the inner wall of the pipe, increasing cleaning efficiency, making it convenient to use, and more practical.
