Negative-pressure pre-stripping device and method for cathode zinc plate

Abstract

The invention discloses a cathode zinc plate negative pressure pre-stripping device and method, mainly comprising a frame, a guide rod and a front and rear telescopic cylinder are fixedly connected to the frame, the guide rod is slidably connected with a vacuum suction cup fixing seat, and a vacuum suction cup fixing seat There is a set of vacuum suction cups on the top, and the vacuum suction cups are used to adsorb on the surface of the cathode plate; the front and rear telescopic cylinders are connected with the vacuum suction cup holders, and are used to drive the vacuum suction cup holders to move back and forth along the guide rod. The front and rear movement of the vacuum suction cup and the front and rear telescopic cylinders are controlled by the electrical system. The vacuum suction cup is adsorbed on the surface of the cathode plate, and the zinc deposits in the suction cup area are removed from the cathode plate by the suction force of the vacuum suction cup and the retraction force of the front and rear telescopic cylinders. face separation. The beneficial effects of the invention are: it is beneficial to realize the automatic process of the zinc stripping unit, the structure is simple and reliable, the stripping efficiency is high, the surface of the cathode plate is protected from damage, the noise on the production site is reduced, and it is environmentally friendly.

Description

technical field [0001] The invention relates to a stripping device and method, which belongs to the technical field of hydrometallurgy tools, and mainly relates to a cathode zinc plate negative pressure pre-stripping device and method. Background technique [0002] 80% of China's 7 million t / y zinc smelting enterprises still use manual stripping. With the increase of labor costs, a large market demand has been formed. However, no matter whether foreign or domestic, there is still a lack of perfect solutions in the market. [0003] At present, the technical bottleneck restricting the automatic stripping of the zinc electrolysis industry lies in the low success rate of pre-stripping. In the electrolytic zinc industry, cold-rolled aluminum plates are used as cathodes. Due to their low hardness, they are easily scratched, and their rigidity is poor, and they are easily deformed. The acid mist corrosion on site is serious, which leads to corrosion and scratches in the liquid leve...

[0002] 80% of China's 7 million t / y zinc smelting enterprises still use manual stripping. With the increase of labor costs, a large market demand has been formed. However, no matter whether foreign or domestic, there is still a lack of perfect solutions in the market

[0003] At present, the technical bottleneck restricting the automatic stripping of the zinc electrolysis industry lies in the low success rate of pre-stripping

In the electrolytic zinc industry, cold-rolled aluminum plates are used as cathodes. Due to their low hardness, they are easy to scratch, and their rigidity is poor and easy to deform. The acid mist corrosion on site is serious, which leads to corrosion and scratches in the liquid level line area, and the surface roughness decreases. The difficulty of stripping is greatly increased
