Description

Technical Field

[0001] The utility model relates to a cathode plate polishing device in the electrolytic metal industry, in particular to a cathode plate combined fixed polishing machine. Background Art

[0002] In the process of electrolytic manganese production, metallic manganese is electrolytically deposited on the cathode plate. After the electrolysis is completed, the electrolytic manganese is stripped from the cathode plate. The cathode plate needs to be soaked and washed with water to make the surface of the cathode plate bright and smooth before it can be used again in the electrolytic manganese production process. For cathode plates with an untidy surface after treatment, surface polishing treatment is required to meet the use requirements. At present, most of the cathode plates in my country's electrolytic metal industry are polished by electrochemical polishing. For example, the utility model patent with the authorization announcement number: CN206467322U discloses "a polishing device for electrolytic manganese cathode plates"; the main disadvantages of electrochemical polishing are high consumables cost, serious pollution, and serious over-polishing. There are also mechanical physical polishing methods for polishing cathode plates, such as the "a cathode plate physical polishing machine" disclosed in the invention patent application with the application publication number CN 112792718A, which uses a polishing roller to polish the cathode plate; and whether it is a polishing roller or a wire brush to grind and polish the cathode plate, the polishing effect is not ideal, and the polishing is not bright. When the cathode plate is deformed or concave, it is difficult to polish. Some fluid polishing machines on the market use colloidal abrasive flow, which can only be used for inner diameter polishing and inner hole polishing of small workpieces. They are not suitable for cathode plates with large areas that require double-sided polishing. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a cathode plate combined fixed polishing machine to solve the shortcomings of the prior art, such as high consumables cost, serious pollution, serious over-polishing and unsatisfactory polishing effect.

[0004] The technical solution to solve the above technical problems is: a cathode plate combined fixed polishing machine, including a cathode plate, a polishing groove, an abrasive, and a driving device. The cathode plate is fixedly installed in the polishing groove, and the polishing groove is filled with the abrasive. The two ends of the polishing groove are respectively connected to the driving device, and the driving device is used to make the abrasive in the polishing groove and the fixed cathode plate produce relative movement to achieve polishing of the cathode plate.

[0005] A further technical solution of the utility model is: there are multiple cathode plates, and the multiple cathode plates are evenly fixedly installed in the polishing tank.

[0007] A further technical solution of the utility model is: the polishing groove is a rectangular open groove, and the bottom of the polishing groove is connected to the base through a spring; the driving device includes a vibration motor, and the output end of the vibration motor is fixedly connected to the groove walls at both ends of the polishing groove.

[0008] A further technical solution of the utility model is that the beam body of the cathode plate is fixedly mounted on the top surface of the polishing groove through a workpiece pressure rod, and the panel of the cathode plate is located in the inner cavity of the polishing groove.

[0009] A further technical solution of the utility model is: the polishing tank is a cylindrical tank body, the bottom of the polishing tank is provided with a discharge feed port, the top of the polishing tank is fixedly installed with a cathode plate mounting frame, the cathode plate mounting frame is provided with a cathode plate hole matching the panel of the cathode plate; the panel of the cathode plate extends into the inner cavity of the polishing tank through the cathode plate hole; the beam body of the cathode plate is pressed and installed on the top surface of the cathode plate mounting frame by a workpiece pressure rod; the driving device includes a motor and a transmission mechanism, and the motor is connected to the polishing tank through the transmission mechanism.

[0010] A further technical solution of the utility model is that a material receiving hopper is installed below the bottom of the polishing tank.

[0014] Furthermore, the driving device of the utility model includes a vibration motor, which is installed at both ends of the polishing tank. Under the vibration of the vibration motor, the abrasive in the polishing tank performs a vortex flow rotation motion, thereby thoroughly polishing the cathode plate.

[0015] In addition, the driving device of the utility model can also include a motor and a reduction mechanism thereof. The motor and its transmission mechanism are installed at the end of the polishing groove. The motor drives the polishing groove to rotate, so that the abrasive in the polishing groove performs a vortex rotation motion under the action of centrifugal force, thereby achieving grinding and polishing of the cathode plate.

[0016] Therefore, no matter the utility model adopts vibration polishing or rotation polishing, the abrasive can make the abrasive do volute rotation motion, so that the abrasive and each part of the cathode plate can be fully ground and contacted, so that the surface, deformation and depression of the cathode plate can be thoroughly polished, and the polishing effect is better.
