Description

Technical Field

[0001] The utility model relates to the technical field of metallurgical equipment, in particular to a spraying and drying device for local anticorrosion layers of zinc electrolysis anode and cathode plates. Background Technique

[0002] In hydrometallurgical zinc smelting, lead-silver alloy plates containing about 1% are used as anodes, and industrial pure aluminum plates are used as cathodes. Zinc is extracted by electrodeposition in zinc sulfate electrolyte. As the main components of zinc hydrometallurgy, the corrosion resistance and service life of the anode and cathode plates are not only related to the production cost of electrolytic zinc, but also affect the electrolysis efficiency and the quality of electrolytic zinc.

[0003] In the existing production process, most of the plate surfaces of the anode and cathode plates are immersed in the electrolytic cell. In this way, local anticorrosion treatment of the anode and cathode plates cannot be carried out. If forced to perform local treatment, manual operation by personnel is required, which is not only troublesome but also has certain potential safety hazards. Therefore, we designed a spraying and drying device for local anticorrosion layers of zinc electrolysis anode and cathode plates to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a spraying and drying device for local anticorrosion layers of zinc electrolysis anode and cathode plates. By turning on the booster pump, the booster pump can pump the anticorrosion coating in the coating tank into the high-pressure pipeline and the spraying pipeline, and then turn on the multi-hole nozzles, so that multiple multi-hole nozzles can spray the local part of the anode and cathode plate body, improving the efficiency and reducing the labor intensity of personnel at the same time, with relatively high safety, so as to solve the problems raised in the above background technique.

[0005] To solve the above technical problems, a spraying and drying device for local anticorrosion layers of zinc electrolysis anode and cathode plates provided by the utility model includes a bracket. On one side of the top of the bracket, there is a coating tank, in which an anticorrosion coating is added. A booster pump is arranged in the coating tank. One side of the coating tank is fixedly inserted with a high-pressure pipeline, which is connected to the booster pump. On the other side of the high-pressure pipeline, there is a spraying pipeline, and multiple multi-hole nozzles are arranged on the spraying pipeline. A rotating motor is arranged on the bracket. The driving end of the rotating motor rotates through the bracket and is provided with a turntable. The anode and cathode plate body is placed on the top of the turntable, and a part of the anode and cathode plate body is located in the spraying pipeline.

[0006] Further, a clamping assembly is provided on the turntable for clamping the main body of the anode and cathode plates. The clamping assembly includes a plurality of claws. A plurality of electric push rods are provided on the turntable. The driving end of the electric push rod is fixedly connected to the claw. An L-shaped member is provided at the other end of the claw. The L-shaped member abuts against the main body of the anode and cathode plates. After the main body of the anode and cathode plates is placed on the turntable, the plurality of electric push rods are turned on, so that the driving end of the electric push rod shortens to drive the claw and the L-shaped member to move and abut against the main body of the anode and cathode plates for clamping, improving the stability.

[0007] Further, a stirring motor is provided on the bracket. The driving end of the stirring motor rotates through the bracket and the paint tank and extends into the paint tank and is fixedly provided with a stirrer. By turning on the stirring motor, the stirring motor can drive the stirrer to rotate and stir the anti-corrosion paint to prevent the paint from settling.

[0008] Further, a feeding port is opened at the top of the paint tank, which is convenient for adding anti-corrosion paint into the paint tank.

[0009] Further, a reducer is provided at the top of the bracket. The reducer is connected to the driving end of the rotating motor, and can decelerate the driving shaft of the rotating motor.

[0010] Further, a drying assembly is also provided on the bracket for drying the main body of the anode and cathode plates with paint. The drying assembly includes a drying box. The drying box is fixedly installed on the top of the bracket. A circulating air motor is provided on the bracket. The driving shaft of the circulating air motor rotates through the bracket and the drying box and extends into the drying box and is provided with a circulating fan. A heater is embedded in the drying box. A hot air duct is fixedly inserted on one side of the drying box. A plurality of hot air nozzles are provided on the hot air duct. Part of the main body of the anode and cathode plates is located in the hot air duct. After spraying, the circulating air motor and the heater are turned on, so that the driving shaft of the circulating air motor can drive the circulating fan to rotate at a high speed. During this process, the circulating fan can blow the hot air inside the drying box onto the main body of the anode and cathode plates through the hot air duct and the hot air nozzles, which can accelerate the drying rate of the paint on the main body of the anode and cathode plates, thereby helping to improve the spraying quality.
