Description

Technical Field

[0001] This invention relates to the field of metallurgical technology, and in particular to a cathode plate for zinc electrolysis using the chloramine process. Background Technology

[0002] Currently, ammonia electrolytic zinc production primarily uses pure aluminum cathode plates, which suffer from problems such as easy corrosion of the liquid surface, poor impact resistance, and difficulty in opening the zinc deposits. Some small factories use pure titanium cathode plates, but these have disadvantages such as high investment costs, poor conductivity compared to aluminum plates, and difficulty in adhering and detaching the deposited zinc over time. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a cathode plate for zinc electrolysis using the chloramine method. This invention solves the problems of high cost, poor conductivity, and poor adhesion of zinc deposits in pure titanium cathode plates. Two titanium plates are located above and below the liquid level of the aluminum plate. The upper part above the liquid level improves the corrosion resistance and impact resistance of the cathode plate, while the lower part facilitates the opening of zinc deposits on the titanium plate. This reduces the labor intensity of workers, facilitates mechanized zinc stripping, extends the service life of the cathode plate, saves production costs, and improves economic efficiency.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A cathode plate for zinc electrolysis using the chloramine process includes a conductive beam, an aluminum plate, and two titanium plates. The lower end of the conductive beam is fixedly connected to the upper end of the aluminum plate. The upper sidewall of the aluminum plate is connected to the two titanium plates by multiple screws. Two lifting lugs are fixedly connected to the top of the conductive beam. A conductive head is fixedly connected to one end of the conductive beam. An insulating sleeve is fitted on the end of the conductive beam away from the conductive head. Insulating strips are fitted on both sidewalls of the aluminum plate.

[0006] Preferably, the two titanium plates are arranged on both sides of the aluminum plate, and the titanium plates serve to prevent corrosion and facilitate the removal of zinc precipitates.

[0007] The present invention has the following beneficial effects:

[0008] The cathode plate of this invention is simple to manufacture, the titanium plate is reusable, and it can also be directly applied to existing pure aluminum cathode plates, solving the problems of high cost, poor conductivity, and poor adhesion of precipitated zinc in pure titanium cathode plates. Two titanium plates are located above and below the liquid level in the aluminum plate. The upper part above the liquid level improves the cathode plate's corrosion resistance and impact resistance, while the lower part facilitates the opening of zinc precipitates on the titanium plate, reducing labor intensity, facilitating mechanized zinc stripping, extending the cathode plate's service life, saving production costs, and improving economic efficiency.

[0013] 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. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0014] Reference Figure 1-3 A cathode plate for zinc electrolysis using the chloramine process includes a conductive beam 1, an aluminum plate 2, and two titanium plates 7. The lower end of the conductive beam 1 is fixedly connected to the upper end of the aluminum plate 2. The upper side wall of the aluminum plate 2 is connected to the two titanium plates 7 by multiple screws 8. Two lifting lugs 3 are fixedly connected to the top of the conductive beam 1. A conductive head 4 is fixedly connected to one end of the conductive beam 1. An insulating sleeve 5 is fitted on the end of the conductive beam 1 away from the conductive head 4. Insulating strips 6 are fitted on both side walls of the aluminum plate 2.

[0015] Two titanium plates 7 are set on both sides of the aluminum plate 2. The titanium plates 7 serve to prevent corrosion and facilitate the removal of zinc precipitates.

[0016] Furthermore, the liquid level of the electrolytic zinc on aluminum plate 2 is as follows: Figure 3 As shown, the two titanium plates 7 are located above and below the liquid level of the aluminum plate 2. The two titanium plates 7 above the liquid level improve the corrosion resistance and impact resistance of the cathode plate, while the two titanium plates 7 below the liquid level facilitate the precipitation of zinc by opening on the titanium plates 7, reducing the labor intensity of workers, facilitating mechanized zinc stripping, extending the service life of the cathode plate, saving production costs, and improving economic efficiency.

[0017] In this invention, two titanium plates 7 are provided, which can play a role in corrosion prevention and facilitate the peeling and opening of zinc deposits. This is more suitable for zinc electrolysis using the chloramine method. The titanium plates 7 are reusable and can also be directly applied to existing pure aluminum cathode plates. This solves the problems of high cost, poor conductivity, and poor adhesion of zinc deposits on pure titanium cathode plates. At the same time, the two titanium plates 7 are located above and below the liquid level of the aluminum plate 2. The two titanium plates 7 above the liquid level improve the corrosion resistance and impact resistance of the cathode plate, while the two titanium plates 7 below the liquid level facilitate the opening of zinc deposits on the titanium plates 7, reducing the labor intensity of workers, facilitating mechanized zinc peeling, extending the service life of the cathode plate, saving production costs, and improving economic efficiency.
