[0030] Working principle: put the bearing ring into the ring device 3, and then the spray nozzle 7 sprays the fluorescent penetrant on the surface of the object to be inspected. The fluorescent penetrant is usually a liquid containing fluorescent substances. This liquid can penetrate into the tiny defects on the surface of the material. Then the fluorescent searchlight detection light 4 is turned on to illuminate the object. Then the fluorescent penetrant that penetrates into the defect will emit bright fluorescence under the action of the fluorescent powder, showing the outline of the defect. The operator can judge the existence, position and size of the defect by observing the display of the display screen 5. After the bearing is sprayed with fluorescent penetrant for inspection, the existing detection device does not have the function of cleaning the fluorescent penetrant on the bearing, so it is necessary to improve this so that the detection device can clean the fluorescent penetrant on the bearing later. When the bearing flaw detection is completed, put the bearing into the screen bucket 11, and then add cleaning liquid to the cleaning powder removal box 8, and then adjust the electric pole 19 to make the stirring shaft 20 enter the screen bucket 11, and then the stirring motor 17 works to drive the stirring shaft 20 to rotate, so that the stirring shaft 20 stirs the bearing in the screen bucket 11. The bearing is fully cleaned in the cleaning liquid. After the cleaning is completed, the electric pole 10 is raised and the electric pole 19 is adjusted to work at the same time, so that the screen bucket 11 floats on the surface of the cleaning liquid. Then the dryer and the heating wire in the heating method drying shell 15 work at the same time to dry the cleaned bearing, so as to facilitate the removal of the fluorescent penetrant sprayed on the bearing. The liquid sprayed by the spray nozzle 7 is prone to splashing everywhere, which affects its working environment. Therefore, the fluorescent penetrant sprayed by the spray nozzle 7 needs to be shielded to avoid the fluorescent penetrant from splashing everywhere. In this case, firstly, the second magnetic block 23 is adsorbed on the first magnetic block 22, and the baffle plate 24 is installed on the outside of the spray nozzle 7.
