Abstract

The invention relates to a device for removing zinc dross in a galvanized wire zinc pot. The device aims at solving the following disadvantages caused due to that the zinc dross in the zinc pot is removed manually at present: as the zinc pot is full of zinc solution, the zinc solution can spill out; the zinc solution can volatilize toxic dust and the temperature is high; therefore, the labor intensity is high, the zinc solution is harmful to human bodies, and potential safety hazards can be incurred. The technical measures of the device are as follows: the device for removing the zinc dross in the galvanized wire zinc pot comprises a supporting post, a guide screw rod connected with the supporting post, a lifting motor, a cantilever structure, a dross scooping mechanism, a PLC controller and a dross pushing mechanism. The device eliminates the potential safety hazards in production, greatly lowers the labor intensity of operating personnel, improves the product quality, lowers the rejection rate and reduces the production cost.
