Description

Technical Field

[0001] This utility model relates to the field of electrolytic cell technology, and in particular to a swirl electrolytic cell. Background Technology

[0002] In industrial applications, cyclone electrolysis technology is emerging as an alternative technology for metal recycling, serving as an effective method for separating and purifying metals. Its structure is relatively simple, requiring less space and having low start-up costs. With lower production costs and higher-quality products, its economic benefits are significant, and it has great potential for development in fields such as metal recycling.

[0003] The cyclone electrolysis unit uses a solution transfer pump to deliver the electrolyte solution from a storage tank into a cyclone electrolysis cell arranged and laid out according to a design. The solution circulates within the system, and valuable metal ions are selectively separated from the electrolyte solution and adsorbed onto the cathode plate through selective electrolysis. The high-speed rotating flow of the electrolyte effectively eliminates concentration differences, enabling efficient recovery of valuable metals from waste liquids with relatively low energy consumption. It also offers advantages in the selective extraction, purification, and separation of various valuable metals.

[0004] However, in traditional electrolysis processes, the electrolyte has poor fluidity, which easily leads to concentration differences during the reaction, thereby reducing product quality. At the same time, the cell voltage will increase, resulting in increased energy consumption. Utility Model Content

[0005] Therefore, the technical problem to be solved by this utility model is to overcome the serious concentration polarization in the electrolysis process of the prior art, which leads to problems such as low current efficiency and poor product quality, making it difficult to achieve efficient and clean extraction of metals.

[0006] To solve the above-mentioned technical problems, this utility model provides a vortex electrolytic cell, comprising: an electrolytic cell shell with a liquid inlet at its lower end and a liquid outlet at its upper end, the electrolytic cell shell being a hollow cylinder, both the liquid inlet and the liquid outlet communicating with the interior of the electrolytic cell shell, the liquid inlet being tangentially oriented along the electrolytic cell shell; a cathode titanium tube disposed inside the electrolytic cell shell, serving as the cathode, the surface of the cathode titanium tube being used for metal deposition, the cathode titanium tube being a rectangular thin plate bent into a ring shape, and used for scraping metal when unfolded; and an anode titanium tube disposed inside the cathode titanium tube, serving as the anode, a gap being provided between the outer wall of the anode titanium tube and the inner wall of the cathode titanium tube. The vortex electrolytic cell of this invention uses a rectangular thin plate wound into a cylindrical shape and vertically installed inside the electrolytic cell shell. The solution entering the electrolytic cell shell tangentially from the bottom can form an upward vortex. The high-speed rotating flow of the electrolyte can effectively eliminate concentration differences and improve the efficiency of desorption. Furthermore, the thin plate wound structure of the cathode titanium tube not only facilitates installation and disassembly but also makes it easy to remove metals.

[0010] In one embodiment of this utility model, an EPDM gasket is provided between the titanium flange and the upper connecting flange, and an EPDM gasket is provided between the titanium flange and the upper perforated flange.

[0011] In one embodiment of this utility model, the upper end of the anode titanium tube is provided with an anode terminal, and the upper end of the anode terminal passes through the upper opening flange.

[0012] In one embodiment of this utility model, PTFE gaskets are provided at the connection positions of the anode terminal and the upper and lower end faces of the upper perforated flange.

[0013] In one embodiment of this utility model, the upper end of the anode terminal extending from the upper perforated flange is provided with a copper nut, a copper washer and a stainless steel locking nut. The stainless steel locking nut locks the upper perforated flange to the upper connecting flange, and a flat washer is provided between the stainless steel locking nut and the upper end face of the upper perforated flange.

[0015] This utility model also provides an electrolysis device, including: an electrolytic cell, an equipment platform, a storage tank, a ball valve one, a magnetic pump, a flow meter, and a ball valve two. The electrolytic cell and the storage tank are both fixedly mounted on the equipment platform. The storage tank is used to store electrolyte. The outlet end of the storage tank is connected to the ball valve one. The ball valve one is connected to the magnetic pump through a pipe. The magnetic pump is connected to the inlet end of the electrolytic cell through a pipe. The flow meter is installed on the pipe between the magnetic pump and the electrolytic cell. The outlet end of the electrolytic cell is connected to the inlet end of the storage tank. The ball valve two is installed on the discharge pipe of the storage tank. The electrolytic cell is the aforementioned vortex electrolytic cell.

[0016] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial effects:

[0017] 1. High-speed water enters the electrolytic cell from below, and the liquid enters from the inner side of the cell and is tangential to it. The liquid enters the cell along the tangential line, thus forming a swirling flow.

After that, the cathode titanium tube is rolled up and put back into the electrolytic cell shell. This structure of the cathode titanium tube facilitates the quick removal of metal, and is also convenient for installation and disassembly, which improves the current efficiency and the quality of the cathode product.
