Description

Technical Field

[0001] This utility model belongs to the technical field of cathode push rods, specifically a cathode feeding device. Background Technology

[0002] A cathode feed device is a mechanical device used in the electrolysis process. It is typically used to control or adjust the position of the cathode in the electrolytic cell. Its main function is to ensure that the cathode can move appropriately or maintain a stable position during electrolysis to promote the smooth progress of the electrolysis reaction. Cathode feed devices are usually designed to operate through the electrolyte.

[0003] For example, in the patent document "CN102896383B", the disclosed "Method and apparatus for electrolytic machining of difficult-to-cut materials and small-module internal gears" has an inlet pipe 18 connected to a cathode connecting rod 3, a cathode connecting rod 3 connected to a cathode tool 4, and electrolyte flowing out of the inlet pipe 18 through the hollow pipe of the cathode connecting rod 13.

[0004] In actual production, the cathode connecting rod is usually in direct contact with the cathode to improve the current conduction efficiency. Therefore, the cathode connecting rod needs to have electrical conductivity. However, the conductive cathode connecting rod is exposed to the electrolyte and is easily corroded by the electrolyte. If the metal part of the cathode connecting rod is in direct contact with the electrolyte, it will cause the current to be dispersed, which will not only reduce the efficiency of the electrolysis process.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] Please refer to Figure 1-6 ;

[0028] A cathode feeding device includes a cathode cylindrical body 1, which includes a connecting part 11 and a liquid delivery part 12. The connecting part 11 is used to connect to the cathode. A corrosion-resistant and lightweight insulating cylinder is fitted on the outer surface of the liquid delivery part 12 near the connecting part 11, and a corrosion-resistant and heat-insulating insulating cylinder is fitted on the outer surface of the liquid delivery part 12 away from the connecting part 11.

[0029] Specifically, the cathode feeding device of this application adopts a segmented insulation design. A corrosion-resistant and lightweight insulating cylinder and a corrosion-resistant and heat-insulating insulating cylinder are respectively fitted onto the liquid delivery section 12 of the cathode cylinder body 1. The corrosion-resistant and lightweight insulating cylinder near the connecting part 11 is used to prevent direct contact between the electrolyte and the cathode cylinder body 1, thereby avoiding damage to the liquid delivery section 12 of the cathode cylinder body 1 by corrosive components in the electrolyte, while also possessing lightweight and good electrical insulation properties. The corrosion-resistant and heat-insulating insulating cylinder farther from the connecting part 11 focuses on heat insulation, effectively reducing the impact of high temperatures during the electrolysis process on the body. The impact of the cathode cylinder body 1: Compared with using a single insulating layer, the segmented design allows for the selection of the most suitable materials for different working environments and requirements, providing stronger corrosion resistance, heat insulation, and electrical insulation, thereby improving the stability and durability of the entire device. In addition, the segmented design also allows for the partial replacement of damaged parts during maintenance of the cathode cylinder body 1, reducing maintenance costs. Compared with not using an insulating layer, the cathode feeding device of this application effectively avoids the risks caused by electrolyte corrosion and excessive temperature, ensuring long-term reliable operation.

[0030] In this embodiment, the corrosion-resistant and lightweight insulating cylinder includes a glass fiber insulating cylinder 2, and the corrosion-resistant and heat-insulating insulating cylinder includes a ceramic insulating cylinder 3; further, a cylindrical groove 4 is provided on the inner wall of the ceramic insulating cylinder 3 near the end of the glass fiber insulating cylinder 2, and a glass fiber cylindrical body 5 is provided on the end of the glass fiber insulating cylinder 2 near the end of the ceramic insulating cylinder 3, and the glass fiber cylindrical body 5 is inserted into the cylindrical groove 4.

[0031] Specifically, the corrosion-resistant and lightweight insulating cylinder is made of glass fiber material, while the corrosion-resistant and heat-insulating insulating cylinder is made of ceramic material. The glass fiber insulating cylinder 2 has excellent corrosion resistance, light weight and electrical insulation, making it suitable for preventing the electrolyte from corroding the infusion section 12 without significantly increasing the weight. The ceramic insulating cylinder 3 has excellent high-temperature resistance and heat insulation, which can effectively isolate the heat generated during the electrolysis process, thus preventing overheating damage. At the same time, the ceramic material also has strong corrosion resistance.

[0032] Furthermore, the insertion and connection between the fiberglass cylinder 5 and the cylindrical groove 4 ensures a secure connection between the fiberglass insulating cylinder 2 and the ceramic insulating cylinder 3, effectively preventing relative displacement or loosening and ensuring sealing and overall stability.

[0033] In this embodiment, a stainless steel cylinder 6 is fitted on the outer surface of the glass fiber insulating cylinder 2, and the end face of the stainless steel cylinder 6 abuts against the end face of the ceramic to further increase the strength of the glass fiber insulating cylinder 2.

[0034] In this embodiment, the inner wall of the glass fiber insulating cylinder 2 and the cathode cylinder body 1 are provided with a gap 7, and the outer surface of the glass fiber insulating cylinder 2 and the inner wall of the stainless steel cylinder 6 are provided with a gap 8. The gap 7 and the gap 8 are filled with glue.

[0035] Specifically, when the electrolyte passes through the cathode feed device, it generates a certain amount of heat. Gap 7 and Gap 8 provide space between the fiberglass insulating cylinder 2 and the cathode cylinder body 1 and stainless steel cylinder 6, allowing for thermal expansion and contraction. This prevents mechanical stress concentration caused by temperature differences. In addition, operators can inject adhesive into Gap 7 and Gap 8 to prevent air from entering. Especially in the electrolyte environment, air entry may cause electrons in the electrolyte to break down the fiberglass insulating cylinder 2, thereby reducing insulation performance. By injecting adhesive into Gap 7 and Gap 8, air can be effectively prevented from entering, preventing the electrolyte from contacting the air and avoiding current leakage or breakdown.

[0036] In this embodiment, the inner diameter of the outer surface of the stainless steel cylinder 6 is the same as the inner diameter of the outer surface of the ceramic insulating cylinder 3; the end face of the ceramic insulating cylinder 3 away from the connecting part 11 is smaller than the outer surface of the ceramic insulating cylinder 3.

[0037] In this embodiment, a connecting block 9 is provided at one end of the liquid delivery section 12 of the cathode cylindrical body 1. A cylinder is provided in the middle of the connecting block 9. The inner wall of the cylinder is connected to the outer surface of the cathode cylindrical body 1. A through groove 10 is provided on the connecting block 9, and the through groove 10 communicates with the cylinder.

[0038] In this embodiment, the connecting part 11 has an annular groove 13 and an annular groove 14, which are used to connect with the cathode.
