Description
Technical Field
[0001] The invention relates to the technical field of scroll disk processing, and in particular to a scroll disk coating surface treatment device. Background Art
[0002] The vortex disk mainly includes a base and a vortex part. The vortex part is arranged at the top of the base. Three lugs are arranged circumferentially on the base. Each lug is provided with a through hole, and the bottom of the base is provided with several grooves. The contour degree of the vortex disk after processing is required to be relatively high. The vortex disk needs to be surface treated after processing. The specific treatment method is as follows: fix several vortex disks on a conductive plate, immerse the vortex disks in the sulfuric acid solution of the oxidation tank body, and then use the conductive plate to energize the vortex disks, use sulfuric acid as the cathode, and use the vortex disks as the anode to perform an oxidation-reduction reaction, thereby forming a coating on the surface of the vortex disk. In the above method, directly fixing several vortex disks on the conductive plate will cause uneven electrification of the vortex disks, and uneven thickness of the coating after surface treatment, which will cause the contour degree of the vortex disk to fail to meet the requirements. In addition, an air pipe for blowing air toward all vortex disks is provided at the bottom of the oxidation tank body to promote the flow of sulfuric acid solution at the vortex disks. However, as the redox reaction proceeds, there are large differences in the flow and concentration of the sulfuric acid solution in different parts of the scroll disk, which can also lead to uneven coating thickness and make the contour of the scroll disk fail to meet the requirements.
