Description

Technical Field

[0001] The utility model relates to the technical field of automatic casting of anode furnace discs, in particular to an automatic batching and spraying device for a powdery release agent. Background Art

[0002] Anode furnace refined copper is the last step of pyrometallurgical copper smelting. It refines and removes impurities from the liquid crude copper from the converter and guides it to the disc casting machine and quantitatively casts it into the copper mold. After the molten copper solidifies, sprays and cools, it forms a qualified anode plate. In order to prevent the copper mold from sticking to the anode copper plate, a layer of release agent needs to be applied to the inside of the copper mold before the molten copper is loaded to help effectively separate the anode plate from the copper mold.

[0003] The original release agent preparation process is fully manual and needs to be prepared according to manual experience. The release agent concentration control is not accurate, and there is often a phenomenon of too thick or too thin. Too high a concentration will cause waste of release agent, and too thin a concentration will affect the demolding effect and reduce the life of the copper mold. In addition, the original release agent preparation process is labor-intensive, and the operation process is dusty, which is not conducive to the health of the operators. In the process of applying the release agent, the release agent needs to be manually sprinkled or applied to the inside of the high-temperature copper mold. The operating environment temperature is high and the operation risk is relatively high. In addition, the quality of manual spraying is uneven, and there are serious problems of waste of release agent and poor copper mold life. Utility Model Content

The medium of the fluidization device 14 is compressed air, and the control signal is given by the control terminal 30.

[0025] The liquid dispensing tank 20 is a cylindrical steel tank body, the top of which is sealed with a flange cover, and is located below the silo 10. The discharge pipe below the discharge device 12 extends into the opening of the flange cover at the top of the liquid dispensing tank 20.
