Description

Technical Field

[0001] The invention relates to the technical field of cleaning a large bracket, in particular to a cleaning process for cleaning white mist on the surface of the large bracket. Background Art

[0002] The large bracket produced by a workshop is a frame-shaped product made of zinc-nickel copper. There is a lot of white mist on the surface of the large bracket [the white mist may come from the production process or production equipment]. The white mist is a mixture of dust and oil, and is firmly attached to the surface of the large bracket. The existence of white mist seriously affects the appearance of the entire large bracket. Figure 1 The diagram shows a large bracket with white mist distributed on the surface. Therefore, before the large bracket is delivered to the customer, a cleaning process is required to clean all the white mist attached to the surface of the large bracket to meet the customer's needs.

[0003] At present, the workshop mainly uses ultrasonic cleaning process to remove the white mist on the surface of large brackets. The specific cleaning method is: first put a certain number of large brackets to be cleaned into the cleaning basket, and then put the cleaning basket into the cleaning tank filled with cleaning liquid, and the cleaning liquid will submerge all the large brackets in the cleaning basket; then turn on the ultrasonic generator in the cleaning tank to achieve ultrasonic cleaning of the large brackets; after cleaning for a period of time, take the cleaning basket out of the cleaning tank. However, the ultrasonic cleaning process used can only clean off part of the white mist on the surface of the large bracket, but cannot completely clean the white mist. There is a technical defect of incomplete cleaning. For this reason, the cleaning can only be repeated many times, which increases the cleaning time of the large bracket, thereby reducing the cleaning efficiency of the large bracket.

[0004] There are also methods that use pickling technology to remove the white mist on the surface of the large bracket. The specific cleaning method is: put a certain number of large brackets into a pickling tank filled with weak acid, and use the weak acid to remove the white mist on the surface of the large bracket; after pickling for a period of time, take the large bracket out of the pickling tank. However, although the pickling process can remove the white mist, the weak acid will also corrode the surface of the large bracket into a piece of micropores, and the large bracket with micropores also affects the appearance of the entire large bracket. For this reason, the micropores on the surface of the large bracket can only be processed separately later, which undoubtedly adds another process and further reduces the cleaning efficiency of the large bracket.

[0005] Therefore, there is an urgent need for a cleaning process that can completely remove the white mist on the surface of the large bracket and greatly improve the cleaning efficiency of the large bracket. Summary of the invention

[0006] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a cleaning process for removing white mist on the surface of a large bracket, which can completely remove the white mist on the surface of the large bracket and greatly improve the cleaning efficiency of the large bracket.

[0007] The purpose of the present invention is achieved through the following technical solution: a cleaning process for cleaning white mist on the surface of a large bracket, which comprises the following steps: S1. A worker takes out a cleaning basket, and welds a plurality of partitions at intervals inside the cleaning basket and on the bottom surface thereof, so that a receiving cavity is formed between every two adjacent partitions; S2, the worker takes out a plurality of large brackets to be cleaned, inserts the lower end of a large bracket into a receiving cavity from top to bottom, and supports the large bracket on the bottom surface of the cleaning basket; the worker repeats step S2 for multiple times, and then the plurality of large brackets can be respectively inserted into the remaining receiving cavities; S3, put the cleaning basket into the electrolytic tank filled with electrolyte, and then put a metal rod into the electrolyte; the worker clamps the negative electrode clamp of the DC power supply to the cleaning basket, and connects the positive electrode clamp of the power supply to the metal rod; then turn on the DC power supply, the current of the DC power supply is 50~60A, at this time, an electric field is formed between the direct power supply, the metal rod, and the large bracket, under the electric field, the hydrogen ions in the electrolyte move toward the large bracket, and the hydrogen ions undergo a reduction reaction after being energized to generate hydrogen, and the hydrogen moves upward along the surface of the large bracket, and the hydrogen gradually washes off the white mist attached to the surface of the large bracket during the upward movement; after electrolysis for 60~80s, the worker turns off the DC power supply, and then takes the cleaning basket out of the electrolytic tank; S4, placing the cleaning basket into a hot water tank filled with hot water, and cleaning the large bracket with the hot water; after cleaning with the hot water, placing the cleaning basket into a cold water tank filled with cold water, and cleaning the large bracket with the cold water, and after cleaning, taking the cleaning basket out of the cold water tank; S5, placing the cleaning basket into an alcohol tank containing alcohol, so that the alcohol adheres to the surface of the large bracket, and then taking the cleaning basket out of the alcohol tank, and after the alcohol evaporates, the large bracket without moisture can be obtained, thereby finally achieving the cleaning of the first batch of large brackets; S6. The worker repeats steps S2 to S5 for multiple times to clean multiple batches of large brackets.

[0008] In step S3, the metal rod is an iron rod, and the electrolyte is water.

[0009] In step S3, the current of the direct power supply is 50A and the electrolysis time is 60s.

[0010] In step S4, the temperature of the hot water is 50°C, and the temperature of the cold water is 6°C.

It can be seen that compared with the ultrasonic cleaning process, this cleaning process does not need to use ultrasound to clean the large bracket multiple times, thereby shortening the cleaning time of the large bracket, and thus greatly improving the cleaning efficiency of the large bracket. In addition, compared with the pickling process, this cleaning process uses hydrogen flushing to clean the white mist on the large bracket, so that no micropores will be formed on the surface of the large bracket, so there is no need to subsequently treat the micropores on the surface of the large bracket separately, thereby greatly improving the cleaning efficiency of the large bracket.

[0014] S4, placing the cleaning basket 1 into a hot water tank filled with hot water, and cleaning the large bracket with the hot water; after cleaning with the hot water, placing the cleaning basket 1 into a cold water tank filled with cold water, and cleaning the large bracket with the cold water, and after cleaning, taking the cleaning basket 1 out of the cold water tank; S5, placing the cleaning basket 1 into an alcohol tank containing alcohol, so that the alcohol adheres to the surface of the large bracket, and then taking the cleaning basket 1 out of the alcohol tank, after the alcohol evaporates, the large bracket without moisture can be obtained, and finally the first batch of large brackets are cleaned. The structure of the cleaned large bracket is as follows: Figure 3 As shown; Among them, in step S5, this cleaning process uses alcohol to remove moisture attached to the surface of the large bracket. Compared with the dehydration by drying, no moisture will be generated on the surface of the large bracket, thereby improving the cleaning quality of the large bracket.

[0015] S6. The worker repeats steps S2 to S5 for multiple times to clean multiple batches of large brackets.

[0016] In step S3, the metal rod is an iron rod, and the electrolyte is water. In step S4, the temperature of the hot water is 50°C, and the temperature of the cold water is 6°C.

Under the electric field, the hydrogen ions in the electrolyte move toward the direction of the large bracket. After the hydrogen ions are energized, a reduction reaction occurs to generate hydrogen. The hydrogen moves upward along the surface of the large bracket. During the upward movement, the hydrogen gradually washes off the white mist attached to the surface of the large bracket; after 80s of electrolysis, the worker turns off the DC power supply, and then takes the cleaning basket 1 out of the electrolytic cell.
