Description

Technical Field

[0001] The utility model relates to the technical field of industrial boilers, and more specifically to a self-descaling industrial boiler. Background Art

[0002] Industrial boilers are equipment used to produce industrial hot water, steam or other heating media. They are commonly found in industrial sites such as chemical plants, power plants, and manufacturing plants. They generate heat energy by burning fuel or using electricity, and then transfer the heat energy to the medium to be heated.

[0003] After searching, a Chinese patent with publication number CN216047806U discloses a smokeless industrial boiler. In view of the existing conventional industrial boilers, a large amount of smoke and dust is easily generated during operation, and it is difficult to deal with it in time, which leads to the problem of pollution of the surrounding working environment. By starting the suction fan, suction will be generated inside the smoking ring, and the smoke and dust generated in the boiler can be sucked into the smoking ring through the smoking pipe, and enter the air supply pipe through the exhaust pipe, and then discharged through the air supply pipe, so that the smoke and dust in the boiler can be discharged in time, and sprayed into the smoking ring through a plurality of atomizing nozzles, so that the smoke and dust sucked into the smoking ring can be subjected to dust reduction treatment, reducing the dust attached to the inside when the smoke and dust are discharged, and effectively reducing the pollution of the smoke and dust to the environment.

[0004] During the use of the industrial boiler, scale is likely to form inside the boiler after long-term use, and the scale is likely to affect the heating effect of the boiler. The industrial boiler is not convenient to automatically clean the scale inside the boiler. Currently, chemical cleaning agents and manual disassembly of the inner tank are generally used for cleaning. The cleaning process is cumbersome and inefficient. Utility Model Content

[0014] Technical effects and advantages of the utility model:

[0015] 1. By setting a descaling mechanism, the threaded sleeve and the moving ring are moved by rotating the threaded rod, so that the connecting rod scrapes the scale on the inner wall of the industrial boiler body, and the scale on the inner wall of the industrial boiler body is brushed off by the brush plate. At the same time, the brush plate is always pressed against the inner wall of the industrial boiler body by the spring rebound force, so as to improve the scale cleaning effect. Compared with the prior art, the scale on the inner wall of the industrial boiler body can be automatically removed, and the scraper scraping and the brush plate brushing are performed at the same time, so the descaling effect is good, and there is no need to manually disassemble the inner tank for cleaning, so the cleaning efficiency is improved, and the use is simpler and more convenient;

[0016] 2. By setting up a medicine feeding mechanism, the medicine pipe injects detergent into the medicine feeding tank, and discharges it into the limiting water pipe through the connecting pipe. The detergent is discharged into the industrial boiler body through multiple medicine outlet holes, further improving the descaling effect. At the same time, the sliding connection between the limiting water pipe and the limiting hole plays a limiting role, preventing the threaded sleeve and the moving ring from rotating with the threaded rod, so that the threaded sleeve and the moving ring move in the horizontal direction for descaling.
