Description

Technical Field

[0001] The utility model belongs to the technical field of water tank processing, and in particular relates to an ultrapure water tank polishing device. Background Art

[0002] An ultrapure water tank is a tank used for rough ultrapure water. Different from conventional water storage tanks, the tanks used to store ultrapure water need to remain rust-free and non-oxidized for a long time to prevent oxidized impurities from dissolving into the ultrapure water and causing the water to be contaminated by the tank.

[0003] Therefore, when producing and processing ultrapure water tanks, more stringent requirements are placed on processing materials and processing technology, and the water tanks need to be fully polished and ground to ensure that they have a very high degree of smoothness.

[0004] At present, large ultrapure water tanks are welded together to form a complete water tank. Before welding, the water tank head, tank body and tank bottom need to be fully polished in sequence. The current grinding and polishing method is to use a grinding and polishing machine. During the grinding process, the grinding and polishing machine evenly grinds and polishes along the four sides of the component.

[0005] However, since the surface area of ​​the can, tank body and tank bottom of the water tank is relatively large, during the grinding process, the grinding equipment needs to be continuously polished along the can, tank body and tank bottom. The disadvantages of this operation are: during the grinding and polishing process, because the surface area is very large, it is cumbersome to polish along the four sides of the tank body parts in turn during the operation; secondly, it is very easy to miss the polishing during the operation, resulting in missing points in the polishing, and the missing point position is the main site for subsequent rust and oxidation.

[0006] Therefore, in order to improve the polishing effect, the method currently adopted is to rotate the tank body parts. However, due to the large volume of the tank body parts, the tank body shakes violently under the polishing force during the rotation process. When shaking, the tank body parts are very likely to hit the loading platform, causing the tank body to be easily deformed.

[0007] Specifically, unlike tanks for special purposes, the thickness and deformation resistance of water tanks are weaker than those of industrial tanks such as reaction tanks, which makes them easily deformed once they are shaken violently, hit or bumped. Utility Model Content

[0008] Based on the above background, the purpose of the utility model is to provide an ultrapure water tank polishing device.

[0009] In order to achieve the above objectives, the utility model adopts the following technical solutions:
