Galvanizing passivation facility

Abstract

Disclosed is a galvanizing passivation facility. The galvanizing passivation facility comprises a passivating tank, a rotating barrel, a power mechanism, a lifting mechanism and a dispersion mechanism. The rotating barrel comprises a rotating frame and a pierced roller. The lifting mechanism comprises an upper gear, a lower gear, a chain and a quasi-L-shaped plate, wherein the chain is meshed with the upper gear and the lower gear. The quasi-L-shaped plate is set in the mode that when the quasi-L-shaped plate upwards moves to the destination, the lower side of the rotating frame is higher than the liquid level of a passivating solution, and when the quasi-L-shaped plate downwards moves to the destination, the lower side of the rotating frame is lower than the liquid level of the passivating solution, and the upper side of the rotating frame is higher than the liquid level of the passivating solution. The dispersion mechanism comprises a connecting rod, a transmission unit and a plurality of dispersion units. The galvanizing passivation facility has the advantages that the passivating solution makes contact with the surfaces of parts to be passivated in an accelerated mode, the parts to be passivated are passivated in a batch mode, the phenomenon that the passivated parts are attached with each other in the batch passivation process, and the part surface passivation can be more uniform and more efficient.

Description

technical field [0001] The invention relates to the technical field of galvanizing. More specifically, the present invention relates to a galvanized passivation device. Background technique [0002] Zinc is an amphoteric metal, neither acid-resistant nor alkali-resistant. If zinc electroplating is not done well after treatment, the coating will soon become dark and white corrosion products will appear one after another. In order to reduce the chemical activity of zinc, a chromate solution is often used for passivation treatment, so that a layer of chromate conversion film is formed on the surface of the zinc layer. The official name of this film is "chromate conversion film", or "passive film of zinc coating". This film forming process is called "galvanized passivation". At present, most of the industry adopts manual passivation, that is, artificially put the galvanized workpiece into the passivation tank and manually stir it. With the development of electroplating equip...

Problems solved by technology

However, compared with automatic passivation, manual passivation is easy to control, convenient to operate, short exposure time after electro-galvanizing, and easy to take emergency measures in the face of emergencies, but manual passivation is difficult to operate for some smaller products increase, manual operation is greatly affected by human factors, and is poor in uniformity and consistency. Inconsistent passivation film will affect the consistency of product corrosion resistance. In order to ensure consistency, it is often used to reduce the amount of processing each time, so will affect the production efficiency of the product
