[0002] In the current electrolysis of copper, lead, and other metals, electrolysis is often used to refine them. Fiberglass (FRP) has become a preferred material for electrolytic cells due to its excellent corrosion resistance, light weight, and high strength. However, traditional FRP electrolytic cells, due to their length and single-side inlet and outlet, experience significant concentration polarization between the plates during the electrolysis process due to inconsistent electrolyte concentrations at the inlet and outlet sides. This reduces electrolysis efficiency and poses significant safety risks.

[0003] For example, Chinese utility model patent publication number CN201065433Y discloses a fiberglass electrolytic cell, comprising a cell body, partitions and baffles arranged in the cell body, and a liquid inlet and a liquid outlet arranged at the front and rear ends of the cell body, a plate support body is arranged between the baffles, the upper end of the plate support body is a rectangular tooth structure with a rectangular crenel, and a rectangular liquid discharge port is provided at the lower end, the two side edges and the bottom edge of the partition are connected to the cell body, and the bottom edge of the partition is provided with a connecting hole, the two side edges of the partition are connected to the cell body, and the bottom edge of the partition is not connected to the cell body, and the bottom edge of the partition is provided with a connecting port.

DETAILED DESCRIPTION

[0021] The following, in conjunction with the accompanying drawings, clearly and completely describes the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments that can be realized by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] like Figure 1-5 As shown, a circulating FRP electrolytic cell comprises: a rectangular cell body 4; a liquid outlet plate 1, which is one inner wall of the rectangular cell body and is evenly distributed with a square grid; a liquid outlet pipe 6, which is located at the bottom of the outer wall of the rectangular cell body and connected to the liquid outlet plate; a water pump 9, one end of which is connected to the liquid outlet pipe; a liquid inlet plate 2, which is located on the other inner wall of the rectangular cell body and connected to the other end of the water pump; and liquid inlet holes 5, which are evenly distributed on the other inner wall of the rectangular cell body and connected to the liquid inlet plate. An overflow port 7 is extended from the top of the other end of the rectangular cell body.

[0023] Preferably, the liquid outlet plate and the liquid inlet hole are in the form of a dense grid, which can evenly absorb and discharge liquid, and are made of fiberglass reinforced plastics, which have good corrosion resistance.

[0024] Preferably, the liquid outlet plate is connected to the liquid outlet pipe, the liquid inlet is connected to the liquid inlet plate, and the liquid outlet pipe and the liquid inlet are connected at the bottom of the electrolytic cell via a water pump. The water pump is preferably a high-temperature water pump, which is heat-resistant and uses polytetrafluoroethylene blades to effectively prevent the blades from being corroded by the electrolyte. The high-temperature water pump also has a relatively slow blade speed, which effectively prevents the blades from being damaged by the impact of substances released by electrolysis.

[0025] Preferably, the device further comprises: an electrolyte inlet 14; an inlet manifold 13, the inlet manifold being horizontally distributed and connected to the electrolyte inlet at its center; and an inlet branch pipe 15, one end of which is connected to the inlet manifold and the other end of which is connected to the outer wall of one end of the rectangular tank. The inlet manifold has a liquid separation function, which can evenly divide the electrolyte flowing from the electrolyte inlet into multiple branches, which flow into the electrolytic cell through the inlet branches.

[0026] Preferably, the liquid inlet branch pipe is installed at the lower end of the electrolytic cell, which can ensure that the inflowing electrolyte is not blocked by the electrode plates, thereby making the lift longer and keeping the electrolyte concentration consistent.

[0027] Preferably, the liquid outlet plate adopts a large-area dense square grid form, which can effectively ensure the uniformity of the liquid outlet and has a small impact on the fluctuation of the electrolyte phase in the electrolytic cell.

[0028] Preferably, the liquid inlet holes adopt a large-area dense circular grid form, which can effectively ensure the uniformity of the liquid inlet and has a small impact on the fluctuation of the electrolyte phase in the electrolytic cell.

[0029] When the liquid outlet plate and the liquid inlet hole work simultaneously, a stable circulation can be formed in the electrolytic cell, which can effectively reduce the concentration polarization between the plates in the electrolytic cell and prevent accidents.

[0030] Preferably, an extreme mud groove 11 is provided at the inner bottom of the rectangular trough body along its length direction. The extreme mud groove 11 is made by grooving at the bottom of the trough body 4 and is wrapped with fiberglass material. It is corrosion-resistant and has high collection efficiency. The circulation can sweep the precipitated solid particles into the extreme mud groove at the bottom of the electrolytic cell, which is convenient for subsequent collection.

[0031] The inner bottom of the rectangular trough is provided with a sewage outlet 12 connected to the extreme mud trough. The sewage outlet is provided with a large chamfer, which can effectively gather and discharge the surrounding dirt.

[0032] When the electrolytic cell begins operation, the metal plate to be refined is placed on the rectangular cell body 4. External electrolyte flows through the electrolyte inlet 14, through the inlet manifold 13, and into the cell body through the inlet branch 15. When the incoming electrolyte reaches the overflow port 7, the electrolyte stops entering the cell. At this point, the electrolytic cell begins electrolysis operation. The electrolyte within the cell is slowly pumped out through the outlet plate 1 and flows through the outlet pipe 6 to the high-temperature water pump 9. The high-temperature water pump 9 then begins operating, pressurizing the electrolyte and causing it to flow back into the cell through the inlet plate 2 and the inlet hole 5, forming a lateral electrolyte circulation within the cell. The electrolyte continuously flows in this circulation, driving the precipitated solid matter to continuously move and accumulate in the extreme mud tank 11, making it easier to clean it later through the manhole. Smaller solid matter that is difficult to clean can be discharged through the drain port 12 by injecting electrolyte into the rectangular cell body 4.

[0033] Preferably, a front foot pedal 3 and a rear foot pedal 8 are provided on the trough body 4 for manual stepping, which facilitates maintenance and installation.
