Description

Technical Field

[0001] The invention belongs to the technical field of cleaning devices, and in particular relates to a cleaning device and method for coated disc parts. Background Art

[0002] Nondestructive testing is a means of inspecting the surface and internal quality of the inspected parts without damaging the workpiece or the working state of the raw materials. Penetrant testing is a detection technology that uses the surface tension of the liquid to detect open defects on the surface of parts. It is one of the five conventional nondestructive testing methods. Penetrant testing is often used to detect surface defects of parts in the manufacturing and maintenance stages of aircraft engines.

[0003] The surfaces of many parts in the field of aerospace engines need to be treated with surface coating. Most of the important parts need to be inspected for surface defects with coating during the inspection process. At the same time, the coating area is not allowed to be contaminated with penetrant fluid. However, the penetrant fluid in the penetration test is a liquid with strong penetration ability and can penetrate all pores. The coating is a porous material and is very easy to absorb the penetrant fluid. One of the difficulties in the entire parts inspection process is that when the entire surface of the part is penetrated, it is impossible to protect the local coating and ensure that the penetrant fluid does not contaminate the coating. The second difficulty is that it is very difficult to remove the penetrant fluid after it enters the coating.

[0004] The efficiency of cleaning the penetrant liquid manually by using a brush head is low. In addition, during the cleaning process, the protective colloid used in the penetrant test is easily splashed onto the cleaned parts, and the penetrant liquid attached to the splashed colloid will contaminate the cleaned parts. Therefore, a cleaning device for cleaning disc parts and avoiding secondary splashing pollution is needed.

[0005] The patent document with announcement number CN116099831A discloses a hanger coating automatic detachment cleaning device, control system and control method, wherein the hanger coating automatic detachment cleaning device includes a housing and a hanger hoisting system, a hanger whipping system, a hanger cleaning system and a hanger drying system arranged in the housing. This patent uses a catenary conveying method to achieve automatic rotation, beating, cleaning, drying and other links to remove dust attached to the hanger surface through the coordination of a specially designed hanger hoisting system, a hanger whipping system, a hanger cleaning system and a hanger drying system. However, for disc-type parts, corresponding mounting fixtures need to be prepared, and the equipment cannot prevent splashing during the cleaning process, which is prone to secondary pollution.

[0006] The patent document with the announcement number CN118808183A discloses the present light-storage self-luminous color-coated board continuous production device and the light-storage self-luminous color-coated board. The problem to be solved by the patent is that the surface of the existing color-coated board must be cleaned first during production, and the color-coated board is generally cleaned by rolling the substrate with a roller brush, and the roller brush will be contaminated with more impurities during the rolling process, and then the impurities remaining on the roller brush during the long-term cleaning process will affect the cleaning efficiency of the color-coated board substrate. The patent uses gears and racks to drive the brush to rotate for cleaning, but the device cannot prevent splashing during the cleaning process. Summary of the invention
