Description

Technical Field

[0001] This utility model relates to the field of electrolytic cell technology, and in particular to a corrosion-resistant composite structure electrolytic cell. Background Technology

[0002] An electrolytic cell consists of a cell body, an anode, and a cathode, with the anode and cathode chambers usually separated by a diaphragm. Based on the electrolyte, they are classified into three types: aqueous solution electrolytic cells, molten salt electrolytic cells, and non-aqueous solution electrolytic cells. When direct current passes through the electrolytic cell, an oxidation reaction occurs at the anode-solution interface, and a reduction reaction occurs at the cathode-solution interface, to produce the desired product.

[0003] Currently, existing electrolytic cells are plated with a nickel layer on their surface to prevent corrosion. However, during use, collisions may occur, causing the nickel plating to break, which exposes the base metal directly to the electrolyte, leading to oxygen corrosion and affecting the performance of the electrolytic cell. Utility Model Content

[0004] The purpose of this invention is to solve the problem that in the operation of existing electrolytic cells, a nickel layer is plated on the surface of the electrolytic cell to prevent corrosion. However, during use, collisions may cause the nickel layer to break, resulting in the base metal being directly exposed to the electrolyte, causing oxygen corrosion and affecting the performance of the electrolytic cell. Therefore, a corrosion-resistant composite structure electrolytic cell is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A corrosion-resistant composite electrolytic cell includes an electrolytic cell body with a corrosion-resistant layer on its inner wall. The top of the electrolytic cell body has a stepped groove, within which an installation frame is placed. Multiple installation plates are fixedly connected to the top of the installation frame. An anode plate is fixedly connected to the bottom of one installation plate, a cathode plate is fixedly connected to the bottom of another installation plate, and a diaphragm is fixedly connected to the bottom of yet another installation plate. A protective net is fixedly connected to the bottom of the installation frame, and a base plate is fixedly connected to the bottom of the protective net. The base plate has multiple filter holes.

[0007] Furthermore, the electrolytic cell body is made of PP board.

[0008] Furthermore, the corrosion-resistant layer is one or two of the following: a nickel plating layer, an alumina ceramic coating, and a titanium-based coating.

[0009] Furthermore, the tops of both the anode plate and the cathode plate are electrically connected with connecting wires.

[0010] Furthermore, a drain pipe is sealed and inserted at one end of the electrolytic cell body, and the bottom plate is located above the drain pipe.

[0011] Furthermore, the other end of the electrolytic cell body is sealed with an inlet pipe, and both the inlet pipe and the outlet pipe are equipped with valves.

[0012] Furthermore, the top of the electrolytic cell body is provided with a cover plate, and two handles are fixedly connected to the top of the cover plate.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The inner wall of the electrolytic cell is protected by a protective net and a base plate to prevent workpieces from bumping into the inner wall of the electrolytic cell, which could damage the corrosion-resistant layer and prevent the base metal from being directly exposed to the electrolyte, thus preventing oxygen corrosion.

[0015] 2. By setting a nickel plating layer on the inner wall of the electrolytic cell body, a corrosion-resistant layer is formed, which plays a role in corrosion resistance to the inner wall of the electrolytic cell body, thereby preventing the electrolyte from corroding the electrolytic cell body.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-5 A corrosion-resistant composite structure electrolytic cell includes an electrolytic cell body 1. The inner wall of the electrolytic cell body 1 is provided with a corrosion-resistant layer 102. The corrosion-resistant layer 102 is one or two of nickel plating, alumina ceramic coating, and titanium-based coating. The nickel plating layer is provided on the inner wall of the electrolytic cell body 1 to form one or two corrosion-resistant layers 102, thereby providing corrosion resistance to the inner wall of the electrolytic cell body 1.

[0024] If two corrosion-resistant layers 102 are selected, the second layer only serves as a backup when the first layer is undamaged. When the first layer is accidentally damaged by external force, the second layer provides temporary protection, giving the user some time to repair the first layer.

[0025] The top of the electrolytic cell body 1 is provided with a groove 2, which has a stepped structure. An installation frame 3 is placed in the groove 2. Multiple installation plates 4 are fixed to the top of the installation frame 3 by bolts. An anode plate 5 is fixed to the bottom of one of the installation plates 4 by bolts. The anode plate 5 undergoes an oxidation reaction, releasing strong oxidants (such as Cl2, ·OH, etc.) to decompose organic matter or oxidize heavy metal ions. A cathode plate 6 is fixed to the bottom of another installation plate 4 by bolts. The cathode plate 6 undergoes a reduction reaction, reducing heavy metal ions to metal element precipitates or generating H2 to promote pollutant adsorption. A diaphragm 7 is fixed to the bottom of another installation plate 4 by bolts.

[0026] The bottom of the mounting frame 3 is fixed with a protective net 9 by bolts, and the bottom of the protective net 9 is fixed with a base plate 10 by bolts. The protective net 9 and the base plate 10 protect the inner wall of the electrolytic cell body 1, thereby preventing the workpiece from bumping into the inner wall of the electrolytic cell body 1 and thus avoiding damage to the corrosion-resistant layer 102. The base plate 10 is provided with multiple filter holes 11.

[0027] The electrolytic cell body 1 is made of PP plate 101. The top of the anode plate 5 and the cathode plate 6 are electrically connected with connecting wires 8. One end of the electrolytic cell body 1 is sealed with a drain pipe 13, from which the electrolyte is discharged. The bottom plate 10 is located above the drain pipe 13. The other end of the electrolytic cell body 1 is sealed with an inlet pipe 12, from which the electrolyte is input into the electrolytic cell body 1. Both the inlet pipe 12 and the drain pipe 13 are equipped with valves 14. The top of the electrolytic cell body 1 is equipped with a cover plate 15. The top of the cover plate 15 is fixed with two handles 16 by bolts, which facilitates the opening and closing of the cover plate 15.

[0028] The working principle of this embodiment is as follows: During use, a nickel-plated layer is formed on the inner wall of the electrolytic cell body 1 to create a corrosion-resistant layer 102, thereby providing corrosion resistance to the inner wall of the electrolytic cell body 1. Then, the valve 14 is opened, and the electrolyte is introduced into the electrolytic cell body 1 through the inlet pipe 13. Next, when a DC voltage is applied from the anode plate 5 and the cathode plate 6, under the action of the electric field, the cations in the electrolyte move towards the cathode, gain electrons at the cathode and undergo a reduction reaction, while the anions move towards the anode, lose electrons at the anode and undergo an oxidation reaction, thus carrying out the electrolysis reaction. The inner wall of the electrolytic cell body 1 is protected by the protective net 9 and the bottom plate 10, thereby preventing the workpiece from bumping against the inner wall of the electrolytic cell body 1 and causing damage to the corrosion-resistant layer 102. After electrolysis is completed, the valve 14 is opened, and the used electrolyte is discharged from the drain pipe 12.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
