Description

Technical Field

[0001] The utility model relates to the technical field of electrochemistry, and in particular to a lifting type electroplating device for metal coating on the surface of powder materials or an electrolysis device for purifying solid wastes such as crystalline silicon. Background Art

[0002] With the rapid development of science and technology, new materials research has become the focus of global competition. Conductive powder, as a key functional material, has found wide application in many industries such as electronics, coatings, plastics and rubber. However, these powder materials usually face the problems of oxidation and corrosion and lack anti-corrosion properties, which limits their application in specific fields. In order to overcome these limitations, electroplating technology is used to plate different metal layers on conductive powders to give the materials a variety of functions such as enhancing conductivity, improving electromagnetic compatibility and preparing magnetic materials.

[0003] For example, taking carbon fiber as an example, due to its excellent axial conductivity and high strength, it is widely used in electronic products and aerospace fields. By electroplating nickel on carbon fiber, not only can its surface conductivity and magnetic loss performance be enhanced, but it can also effectively shield electromagnetic radiation and ensure the stable operation of equipment and systems. Similarly, although copper powder has good conductivity, it easily reacts with oxygen in the air to generate copper oxide, resulting in a decrease in conductivity. By plating a dense layer of nickel on the surface of copper powder, oxygen can be prevented from reacting directly with copper, thereby significantly improving its oxidation resistance and service life. However, the discontinuous characteristics of powder materials make it difficult to directly connect to the electrochemical circuit for electroplating, which limits its wide application. Therefore, exploring electroplating processes suitable for conductive powders can not only expand its scope of application, but also have important significance for enhancing market competitiveness.

[0004] Prior art 1: A metal-coated composite powder electroplating device

[0005] Application number: 201711362736.3, application date: 2017.12.18, publication (announcement) date: 2018.05.25.

[0006] Prior art 1 specifically introduces a composite powder electroplating device. The working principle of the device includes: it mainly works through a specially designed electroplating tank, which is composed of a conductive shell and is internally divided into two cavities: an inner cavity and an outer cavity. This separation is achieved by a permeable ceramic film installed in the tank. During the electroplating process, the negative pole of the power supply is connected to the conductive shell, and the positive pole extends into the inner cavity, which is filled with metal powder as an anode. In this way, when the current passes through, the metal powder in the inner cavity precipitates metal cations, and the shell reduces these cations to form a dense and uniform metal coating. The entire system is used in conjunction with a circulating pump and a liquid storage tank to ensure that the plating solution can circulate from the liquid storage tank through the electroplating tank, and the flow of the plating solution is controlled by the liquid inlet and the liquid outlet.

[0007] However, there are some limitations in the prior art 1. The permeable ceramic membrane needs to allow a certain degree of electron exchange while preventing the passage of the electroplating solution. The physical stability and chemical durability of the membrane are difficult to meet the requirements. The chemical stability of the electroplating solution is difficult to ensure, and it is difficult to accurately control its chemical composition during the electroplating process.

[0008] Prior art 2: A device for electroplating nano-micron powders

[0009] Application number: 202223495614.0, application date: 2022.12.27, publication (announcement) date: 2023.05.23.

[0010] Prior art 2 discloses a device for nano-micron powder electroplating, which relates to the field of powder electroplating, including an electroplating chamber, an ultrasonic probe, a DC power supply, a liquid storage chamber, a first vacuum pump and a second vacuum pump, wherein a cathode current collector and an anode current collector are arranged in the electroplating chamber, and a negative power supply electrode and a positive power supply electrode are arranged on the DC power supply, wherein the negative power supply electrode and the positive power supply electrode are both connected to the electroplating chamber, and the end of the negative power supply electrode is connected to the cathode current collector. The utility model provides a device for nano-micron powder electroplating, which integrates electroplating tools, dispersion tools and stacking tools, and replaces the operation of electroplating-ultrasound-stack-electroplating that needs to be repeated for multiple cycles in nano-micron powder electroplating. It improves the working efficiency of nano-micron powder electroplating, simplifies the operation steps, and can produce nano-micron powders with uniform and dense coating, which is very suitable for nano-micron powder electroplating.

[0011] However, in the prior art 2, the electrode adopts a fixed structure, which leads to a weak collision effect between the electrode and the powder material, a small contact area, and a low electroplating efficiency; if the ultrasonic crushing is not uniform and thorough enough, it will also cause problems such as agglomeration of the powder material.

[0012] Through the above search, it is found that the above technical solutions do not affect the novelty of the utility model.

[0013] In addition, with the increasing demand for high-tech products, silicon-based semiconductors are one of the key materials for manufacturing semiconductor high-tech products such as solar cells and integrated circuits, and their purity and lattice structure are crucial to device performance. In the production process of silicon-based semiconductor wafers, the required wafers are obtained by cutting rod-shaped semiconductors. This process produces a large amount of cutting waste, including silicon sawdust and fragments. The cutting waste contains various organic residues, metal impurities and oxide layers, which will affect the quality and performance of semiconductor materials. The current traditional methods usually include chemical dissolution, melt recrystallization, vapor deposition, rough purification and mixing. However, traditional purification methods may have problems such as high processing cost, high energy consumption, complex process and high environmental pollution. It can be seen that how to deal with semiconductor cutting waste is not only related to product quality, but also to environmental protection and resource utilization efficiency. Therefore, the development of efficient, environmentally friendly and economical waste purification technology is of great significance to the semiconductor industry.

[0014] Compared with ordinary materials, powder materials have the characteristics of small particle size, large specific surface area, and low density, which makes them less likely to be exposed to electrochemical reactions during electrolysis, easy to agglomerate, and difficult to electrolyze. This may be the reason why there are few studies on powder electrolysis, which also makes the development of powder electrolysis purification equipment slow and difficult to achieve large-scale industrial production. Traditional methods have corresponding limitations.

[0015] Electrolysis and electroplating are reverse processes. The technical problems faced by electroplating of powder materials and electrolytic purification of crystalline silicon powder waste (SPW) have certain similarities. The electroplating device for powder materials can be expected to be used as an electrolytic device for purifying crystalline silicon powder waste (SPW) by adjusting the electrode arrangement. This will make it possible to solve the problems of electroplating of powder materials and electrolytic purification of crystalline silicon powder waste (SPW) based on the same device.
