Description

Technical Field

[0001] This invention belongs to the field of cathode plate production technology for wet zinc smelting. Specifically, this utility model relates to a zinc electrowinning cathode aluminum plate with thickened sides. Background Technology

[0002] Zinc electrolytic deposition refers to the process of depositing zinc ions from zinc sulfate electrolyte onto the cathode using anode and cathode plates under the action of direct current. It is a core step in the hydrometallurgical zinc smelting process. After being stripped and dried, the zinc is melted and cast into zinc ingots.

[0003] Zinc electrolytically deposited onto the surface of the cathode aluminum plate, to prevent the deposited zinc from sticking to both sides of the plate and making it difficult to peel off, cathode insulating strips are usually installed on both sides of the cathode plate to prevent zinc ion adhesion. Existing technology involves slotting the sides of the cathode aluminum plate and filling them with insulating material for barrier purposes, reducing the area occupied by the insulating material, increasing the electroplating area, and thus increasing the yield per unit of zinc deposition and economic benefits. However, the slotting operation is limited by the width of the cathode aluminum plate, and the slotting technology is technically difficult, requires sophisticated equipment, and has high processing costs. Therefore, it is essential to develop and produce a cathode aluminum plate that facilitates both side slotting and zinc peeling. Summary of the Invention

[0004] To overcome the problems existing in the background technology, this utility model discloses a zinc electrowinning cathode aluminum plate with thickened sides. The thickened zinc electrowinning cathode plate is constructed by extruding the two sides of the cathode aluminum plate into wide strips, thus widening the two sides of the cathode aluminum plate. The widened strips facilitate the cutting of grooves into inner grooves from the sides of the cathode aluminum plate. An insulating material is applied to the inner grooves to form an insulator. The insulator separates the front and back sides of the cathode aluminum plate from the side, preventing zinc electrowinning and thus adhering the two sides of the front and back sides together. During electrolysis, zinc electrowinning adheres to the front and back sides of the cathode plate, while no zinc adheres to the sides of the cathode aluminum plate. This facilitates the peeling operation when peeling the electrowinning zinc downwards from the zinc stripping opening.

[0005] To achieve the above objectives, this utility model employs the following technical solution: The zinc electrowinning cathode plate with thickened sides is characterized in that it comprises: a cathode aluminum plate, a conductive beam, a hanging ear, a conductive head, a zinc stripping opening, a widening strip, and an insulator; the conductive beam is disposed on the top of the cathode plate, the hanging ear is disposed on the top surface of the conductive beam, the cathode aluminum plate is extruded and formed with widening strips on both sides, the sides of the widening strips are recessed with inner grooves, and insulating material is coated from the inner grooves on the sides of the widening strips to form an insulator.

[0006] As a preferred embodiment, the product includes: a hanging ear; the hanging ear is disposed on the top surface of the crossbeam.

[0007] Preferably, the plate includes a zinc stripping opening; the zinc stripping opening is disposed on the front and back sides of the cathode aluminum plate.

[0008] As a preferred embodiment, the product includes a tongue; the tongue is located at the bottom of the crossbeam, and an aluminum plate mounting slot is recessed on the bottom surface of the tongue.

[0009] Preferably, the device includes an upper plug, which is disposed on the top surface of the cathode aluminum plate.

[0010] Preferably, the device includes a conductive head, which is connected to the crossbeam.

[0011] The beneficial effects of this utility model are as follows: The cathode aluminum plate of the zinc electrowinning cathode plate with thickened sides is extruded and has widening strips on both sides. These widening strips facilitate the cutting of inner grooves from the sides of the cathode aluminum plate, where insulating material is applied to form an insulator. This insulator separates the front and back sides of the cathode aluminum plate from the sides. During electrolysis, zinc electrowinning adheres to the front and back sides of the cathode plate, while no electrowinning zinc adheres to the sides. This facilitates the peeling operation when the electrowinning zinc is peeled off from below the zinc peeling openings on the front and back sides of the cathode aluminum plate.

Detailed Implementation

[0014] To make the above objectives, technical solutions and beneficial effects clearer and more explicit, the present invention will be described in detail below with reference to the accompanying drawings.

[0015] like Figure 1-4 As shown, the zinc electrolytic cathode plate with thickened sides includes a cathode aluminum plate 1, a crossbeam 2, a hanging ear 3, a widening strip 4, and an insulator 5. The crossbeam 2 is located on the top of the cathode aluminum plate 1, the hanging ear 3 is located on the top surface of the crossbeam 2, and a conductive head 10 is located on the bottom surface of the crossbeam 2. The cathode aluminum plate 1 is extruded into widening strips 4 on both sides, and inner grooves 9 are recessed on the sides of the widening strips 4. Insulating material is applied from the inner grooves 9 on the sides of the widening strips 4 to form the insulator 5.

[0016] The bottom of the crossbeam 2 is provided with a tongue 7, and the bottom surface of the tongue 7 is recessed with an installation slot. The top surface of the cathode aluminum plate 1 is provided with an upper plug 8. When the crossbeam 2 is installed on the top surface of the cathode aluminum plate 1, the upper plug 8 is inserted into the bottom of the installation slot of the tongue 7. The two sides of the cathode aluminum plate 1 are aligned with the tongue 7 and embedded into the crossbeam 2 before welding. The welding operation completely seals any gaps in the upper plug 8 inserted into the installation slot of the tongue 7, and the cathode aluminum plate 1 is stably connected to the crossbeam 2. The front and back of the cathode aluminum plate 1 are provided with zinc stripping openings 6.

[0017] The widening strip 4 widens both sides of the cathode aluminum plate 1. The widening strip 4 is obtained by extruding the cathode aluminum plate on an extrusion device. The extrusion operation involves pre-reserving extrusion edges on both sides of the cathode aluminum plate 1, clamping the front and back sides of the cathode aluminum plate 1 using the extrusion device, and then extruding the reserved edges of the cathode aluminum plate 1 into shape using an extrusion die. The extrusion device can extrude widening strips 4, 8-10mm thick and 6mm wide at the top, from both sides of a 5-7mm thick cathode aluminum plate 1. The extrusion edges of the cathode aluminum plate 1 are beveled. The widening strip 4 facilitates slotting into an inner groove 9 from the side of the cathode aluminum plate 1. The inner groove 9 is milled from the center of the side of the widening strip 4 using an angle grinder. The widening strip 4 prevents inconvenience in slotting the inner groove 9 due to the cathode aluminum plate 1 being too narrow. After milling and slotting, the top of the cathode aluminum plate 1 is cut into an upper plug 8 using an angle grinder.

[0018] Insulators 5 are provided on the sides of the widened strips 4 on both sides of the cathode aluminum plate 1. The insulators 5 are obtained by repeatedly brushing insulating material from the inner tank 9. Grooving with an angle grinder roughens the surface of the inner tank 9, facilitating the adhesion of the insulating material. After cleaning the inside of the inner tank 9 with alcohol, the insulating material is applied repeatedly to achieve the effect of the insulators 5. The insulating material is repeatedly brushed and filled into the inner tank 9. After repeated brushing and drying, the inside of the inner tank 9 is filled with insulating material. Then, the insulating material is repeatedly brushed along the outside of the inner tank 9, along the outside of the widened strips 4. After repeated brushing and drying, the shape of the insulators 5 is formed. The insulating coating material is an epoxy engineering adhesive, model 7S470A or 7S470B. This insulating material has low fluidity, making it easy to apply and form. After the insulating material is repeatedly coated to form the insulator 5, the insulator 5 is stably adhered to the side of the widening strip 4. The width of the insulator 5 is the same as the width of the widening strip 4. The insulator 5 is at the same height as the cathode aluminum plate 1. The setting of the insulator 5 can separate the front and back of the cathode aluminum plate 1.

[0019] When the thickened zinc electrowinning cathode aluminum plate 1 is used, insulating material is repeatedly applied to the inner tank 9 on both sides of the insulator 5 to form the insulator 5. The insulator 5 separates the front and back of the cathode aluminum plate 1, and the insulator 5 isolates the cathode aluminum plate 1 into a separate electrowinning zinc attachment area. The cathode aluminum plate 1 is immersed in the electrolytic cell. During the electrolysis process, zinc electrowinning adheres to the front and back of the cathode plate. There will be no zinc electrowinning adhering to the side of the cathode aluminum plate 1. The electrowinning zinc can be peeled off downward from the zinc peeling opening 6 on the front and back of the cathode aluminum plate 1. The peeling operation is convenient.

[0020] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
