Impurities can be attached to the inner wall of the epichlorohydrin production equipment after the epichlorohydrin production equipment is used for a long time, and the stirring blades of the epichlorohydrin production equipment can stir and clean the inner wall of the epichlorohydrin production equipment, but the inner wall of the epichlorohydrin production equipment is difficult to clean. In this setting, the driving piece 6 adsorbs ring body 1 through the magnetism suction between second magnetic part 7 (for example magnet piece) and the first magnetic part 2 (for example magnet piece), and then drives ring body 1 and remove, and brush body 5 can wash impurity, and ring body 1, upper scraper 3 and lower scraper 4 can strike off the impurity of epichlorohydrin production facility lateral wall internal surface, and the impurity of clearance can be discharged through the drain pipe of epichlorohydrin production facility.

Further, a spring 19 may be disposed in the second slideway 17, and the spring 19 may push the first slider 12 to move elastically. When encountering the impurities with firm adhesion, the upper scraping plate 3 is firstly contacted with the impurities and is blocked by the impurities so as not to continue rotating, and in the process of continuing rotating the ring body 1, the elastic force of the spring 19 is gradually increased, and the thrust to the upper scraping plate 3 is gradually increased so as to scrape and clean the impurities.
The same second slideway 17 can be provided with a plurality of second sliding blocks 18, and each second sliding block 18 is supported by a spring 19 in a collision manner, so that the second sliding blocks can be prevented from collision with each other.
