Description

Technical Field

[0001] The utility model relates to the technical field of carbon electrodes, in particular to a carbon sheet electrode forming device. Background Art

[0002] Using a carbon sheet as an anode, electroplating an iron sheet on the surface of the carbon sheet in combination with electroplating, and electrochemically synthesizing ferrate using a carbon sheet electroplated with metallic iron as an anode is a method for preparing ferrate under mild reaction conditions. However, during the use of traditional carbon sheet electrodes, after the metal ions are precipitated, a dense oxide film is easily formed on the surface of the carbon sheet, which affects the use of the carbon sheet electrode and hinders the further occurrence of the electroplating reaction. In order to solve the above problems, the carbon sheet electrode is artificially provided with different pore defects during the preparation process of the carbon sheet electrode, which can effectively avoid the problem of forming a dense oxide film after the metal ions are precipitated. In order to obtain the above carbon sheet electrode, it is necessary to improve the molding mold of the carbon sheet electrode. Utility Model Content

[0022] In order to further explain the technical solution of the present utility model, the present utility model is described in detail below through specific embodiments.

[0023] A carbon sheet electrode forming device, such as Figure 1-Figure 4 As shown, it includes a chassis 1, a pressing block 2 and a molding box 3 clamped between the chassis 1 and the pressing block 2. The chassis 1 includes an integrally formed chassis body 11 and a chassis boss 12, and the chassis boss 12 is arranged on the chassis body 11. The pressing block 2 includes an integrally formed pressing block body 21 and a pressing block boss 22, and the pressing block boss 22 is arranged on the pressing block body 21. The size and shape of the chassis boss 12 and the pressing block boss 22 are adapted. In this embodiment, the pressing block 2 and the chassis 1 are both square. The lower end of the pressing block boss 22 is evenly provided with a plurality of convex nails 221 for making holes, and each convex nail 221 abuts against the upper end of the chassis boss 12.

[0024] like Figure 3 and Figure 5 As shown, the molding box 3 is a hollow square box, the lower end of the molding box 3 is clamped outside the chassis boss 12, and the upper end of the molding box 3 is clamped outside the block boss 22. A gap for molding carbon sheet electrodes is formed in the molding box 3 between the upper end of the chassis boss 12 and the lower end of the block boss 22.

[0025] After adopting the above structure, the utility model provides a carbon sheet electrode forming device. When forming the carbon sheet electrode, the forming box 3 is first clamped on the chassis 1, and then the carbon powder is spread flat in the forming box 3, the pressing block 2 is clamped with the forming box 3, and then pressure is applied to the pressing block 2 by a pressure device, so that a carbon sheet electrode is formed between the chassis boss 12 and the pressing block boss 22. Since a plurality of convex pins 221 are provided at the lower end of the pressing block boss 22, when forming the carbon sheet electrode, holes are directly made on the carbon sheet through the convex pins 221 to form a carbon sheet electrode with a porous structure. This carbon sheet electrode can avoid the formation of a dense oxide film on the entire sheet during use, thereby ensuring the smooth progress of the electroplating reaction.

[0026] Better, such as Figure 4 As shown, each convex nail 221 is circular, which ensures that the formed carbon sheet electrode is not easily damaged and meets the mechanical structure performance.

[0027] The above embodiments and drawings do not limit the product form and style of the present utility model. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present utility model.
