Description

Technical Field

[0001] The utility model belongs to the technical field of polishing liquid pretreatment, in particular to an auxiliary material adding device for polishing liquid pretreatment. Background Art

[0002] Polishing liquid is a water-soluble polishing agent that does not contain any sulfur, phosphorus, or chlorine additives. It is usually composed of solid particle abrasives, surfactants, stabilizers, oxidants and other ingredients. Before the polishing operation, the polishing liquid needs to be pretreated to ensure that the polishing liquid can fully exert its function and achieve the expected polishing effect. During the pretreatment process, an auxiliary feeding device is required, that is, the concentration of the chemical agent is adjusted according to the different polishing objects; the current auxiliary feeding method is to use a control solenoid valve to open and close to realize the chemical agent adding operation, and the polishing liquid and chemical agent are stirred by a stirring rod to realize the pretreatment operation of the polishing liquid.

[0003] According to the above, there is an auxiliary feeding device for polishing liquid pretreatment, but it still has shortcomings in actual use. The most obvious one is that when the chemical agent is added, some of the agent is likely to remain on the inner wall of the feed. In order to remove the chemical agent residue, additional cleaning steps and costs may be required, which not only increases the time and cost investment in the production process, but may also affect production efficiency and flexibility. In addition, when the chemical agent is added, it is easy to stratify with the polishing liquid. At present, most stirring actions are horizontal stirring actions, and the mixing effect is poor, which reduces the working efficiency of the auxiliary feeding device. For this reason, we propose an auxiliary feeding device for polishing liquid pretreatment. Utility Model Content

At this time, the rotating drum rotates on the positioning rod and drives the stirring rod to rotate with the positioning rod as the axis. At this time, the stirring rod drives the second cone wheel to rotate.
