Description

Technical Field

[0001] The utility model relates to the technical field of fluorescent penetrant flaw detection, in particular to a fluorescent penetrant cleaning device. Background Art

[0002] Fluorescent liquid penetrant testing is a method of flaw detection that uses a penetrant containing fluorescent substances to penetrate the workpiece to be inspected. After penetration and cleaning, the penetrant remaining in the defect is adsorbed by the developer. The fluorescent substance is irradiated with an ultraviolet light source to produce visible light with a longer wavelength. The surface of the workpiece after irradiation is observed in a dark room, and the size, location and shape of the defect are determined by the fluorescent image that appears. When cleaning the workpiece after penetration, a corresponding cleaning device is required.

[0003] A fluorescent penetration cleaning device provided by publication number "CN207952100U" uses a bowl-shaped nozzle to increase the water cleaning area and improve cleaning efficiency. At the same time, the nozzle direction is adjusted in conjunction with the adjustment rod to make the workpiece cleaning more comprehensive. The outer baffle is used to fully absorb the water flow to prevent water splashing, and a boss is set on the intermediate baffle to guide the direction of the water flow.

[0004] However, the above technical solutions and the prior art have the following defects:

[0005] Although the cleaning equipment can clean the workpiece, the outer baffle alone cannot effectively block the splashing of water, resulting in some flushing water splashing outward during actual use. The splashed water is mixed with fluorescent penetrant and will contaminate the surrounding ground. In addition, the cleaning equipment cannot air-dry the workpiece after flushing, resulting in dripping of the workpiece during the process of being picked up and transferred, and the practicality is poor.

The upper side of the annular side of the cleaning pool 1 is fixedly connected to the support frame 41, and the support frame 41 is concave in shape. The concave support frame 41 can support the electric push rod. An electric telescopic rod 47 is installed in the middle position of the upper end surface of the support frame 41. The electric telescopic rod 47 can drive the spray plate 43 to move up and down through the connecting frame 46. The lower end of the electric telescopic rod 47 is connected to the connecting frame 46. The connecting frame 46 is concave in shape, and is connected to the spray plate 43 by welding. The connecting frame 46 with a concave shape can support the spray plate 43. The spray plate 43 is fixedly connected to the bottom of the connecting frame 46. The spray plate 43 can disperse the water or air guided by the collecting pipe 44 to multiple nozzles 431. The collecting pipe 44 is fixedly connected to the inlet of the upper end surface of the spray plate 43. The collecting pipe 44 is respectively connected to the first valve 45, the second valve 51 and the spray plate 43. The collecting pipe 44 can guide the water discharged from the first valve 45 or the air discharged from the second valve 51 to the spray plate 43.
