[0001] The utility model relates to the technical field of heating pipelines, and more specifically to a descaling device for high-temperature industrial waste heat centralized heating pipelines. Background Art

[0002] When high-temperature industrial waste heat centralized heating pipelines transport hot water for a long time, the hot water contains certain impurities. After a long period of accumulation and precipitation, the impurities will form scale. The scale will be deposited on the inner wall of the pipeline, reducing the inner diameter of the pipeline and reducing the water output of the pipeline. Therefore, the heating company needs to descale the inner wall of the heating pipeline before the formal heating every year to ensure the normal operation of the heating.

[0021] The interior of the mobile box 1 is provided with a descaling agent tank 2, a water tank 3, a first high-pressure pump 4, a second high-pressure pump 5 and an energy storage battery 24.

The output end of the energy storage battery is respectively connected to the power input end of the driving mechanism, the descaling mechanism, the first high-pressure pump and the second high-pressure pump.

[0022] The driving mechanism includes a driving wheel 16 and a driving motor 15. The driving wheels 16 are provided in two groups, which are symmetrically arranged on the upper and lower sides of the mobile box 1 through the driving wheel mounting bracket 23. Each group of driving wheels consists of two front and rear driving wheels. Four driving wheels are provided on the mobile box 1. The rotating shafts of the four driving wheels are respectively connected to the motor shaft of the driving motor 15 through belts 17. The driving motor drives the driving wheels to rotate, thereby realizing the movement of the mobile box 1 in the heating pipe.

[0023] A guide groove 19 is provided on the mobile box 1, and the driving wheel mounting seat 23 is arranged in the guide groove 19 through the guide rod 20. A buffer spring 21 is provided between the top end of the guide rod 20 and the bottom end surface of the guide groove 19. When the mobile box moves in the heating pipe, the driving wheel can be adaptively adjusted according to the inner wall of the pipe through the buffer spring to ensure that the mobile box can smoothly pass through the heating pipe and achieve descaling of the inner wall of the heating pipe.

[0024] The descaling mechanism includes a rotating shaft 7 arranged at the front end of the mobile box 1, and a rotating motor 6 is arranged inside the mobile box 1. The motor shaft of the rotating motor is connected to the rotating shaft 7 to drive the rotating shaft to rotate. A first rotating disk 8 and a second rotating disk 10 are sequentially arranged on the rotating shaft 7. High-pressure nozzles 9 are evenly arranged on the circumference of the first rotating disk 8. The high-pressure nozzles 9 are connected to the first high-pressure pump 4 to spray descaling water onto the inner wall of the heating pipe to soften the scale on the inner wall of the heating pipe and improve the descaling effect.

[0025] Scrapers 11 and steel brushes 12 are evenly arranged on the circumference of the second rotating disk 10 through the mounting seat 18. The scrapers and steel brushes are arranged at intervals to remove the softened scale.

A limit block 22 is provided at the end of the guide rod 20, and a buffer spring 21 is provided between the limit block 22 and the bottom end surface of the guide groove 19. When the scraper and the steel brush are descaling the inner wall of the heating pipe, the buffer spring can be compressed and adjusted according to the thickness of the scale, which not only improves the descaling effect, but also protects the scraper and the steel brush, thereby increasing the service life of the scraper and the steel brush.

[0027] The flushing mechanism is arranged at the rear of the mobile box body, and is used to flush the inner wall of the pipe after descaling to prevent scale from remaining on the inner wall of the pipe. The flushing mechanism includes a fixed plate 13 arranged at the rear end of the mobile box body 1, and a plurality of high-pressure nozzles 9 are evenly arranged on the surrounding side of the fixed plate 13. The high-pressure nozzle 9 is connected to the second high-pressure pump 5 and is used to flush the inner wall of the high-temperature pipe.

[0028] A traction ring 14 is provided behind the fixed plate 13 , to which a traction rope is connected for pulling the mobile box out of the heating pipe when the descaling device fails.

[0029] When the utility model descales the heating pipe, the descaling agent and water are respectively put into the descaling agent box and the water tank, and then the mobile box is put into the high-temperature pipe that needs to be descaled. After starting, the driving motor drives the driving wheel to move forward in the high-temperature pipe. During the moving process, the high-pressure nozzle at the front end sprays the descaling water onto the inner wall of the high-temperature pipe to soften the scale on the inner wall of the high-temperature pipe, and the scale on the inner wall of the pipe is scraped off by the rotating scraper and steel brush at the rear. The high-pressure nozzle at the rear of the mobile box sprays water onto the inner wall of the high-temperature pipe to flush the high-temperature pipe, thereby flushing away the scale on the high-temperature pipe and avoiding scale residue, thereby improving the descaling effect of the high-temperature pipe.
