[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0032] Embodiment: As Figures 1 to 6 shown, an electrolyte storage tank includes a tank body 1, and a liquid inlet pipe 2 and a liquid outlet pipe 3 are installed inside the tank body 1; both the liquid inlet pipe 2 and the liquid outlet pipe 3 are structures with one end closed and the other end open:

[0033] Among them, the open end of the liquid inlet pipe 2 is used to connect to a liquid inlet system (not shown); a plurality of first through holes 21 are provided on the liquid inlet pipe 2, and the first through holes 21 connect the inner cavity of the liquid inlet pipe 2 with the inside of the tank body 1;

[0034] Among them, the open end of the liquid outlet pipe 3 penetrates through the tank body 1 and is used to communicate with a working system (not shown); a plurality of second through holes 31 are provided on the liquid outlet pipe, and the second through holes 31 connect the inner cavity of the liquid outlet pipe 3 with the inside of the tank body 1.

[0035] During implementation, a tank cover 15 is provided at the top of the tank body 1.

[0036] In this application, by providing a first through hole on the liquid inlet pipe, the high-concentration electrolyte can flow more quickly from the liquid inlet pipe into the tank, and come into more sufficient contact with the low-concentration electrolyte in the tank, thereby making the electrolyte concentration in the entire tank more uniform. At the same time, a second through hole is provided on the liquid outlet pipe, allowing the electrolyte in the tank to enter the interior of the liquid outlet pipe more quickly and then enter the working system.

[0037] During implementation, a pump can be used to better introduce the liquid in the liquid outlet pipe 3 into the working system.

[0038] Specifically, there are two liquid inlet pipes 2 respectively arranged on opposite sides inside the tank 1, and the open ends of the two liquid inlet pipes 2 are connected through a T-shaped connecting pipe 22. The liquid inlet end of the T-shaped connecting pipe 22 penetrates the side wall of the tank 1 and is used to communicate with the liquid inlet system.

[0039] In this way, the two liquid inlet pipes can make the reacted electrolyte flow into the electrolyte storage tank more uniformly.

[0040] Specifically, the first through holes 21 are arranged in two symmetric columns on the lower side of the liquid inlet pipe 2. Among them, the axial lines of two first through holes 21 in the same row intersect at an angle of 60°.

[0041] Specifically, the second through holes 31 are arranged in two symmetric columns on the upper side of the liquid outlet pipe 3. Among them, the axial lines of two second through holes 31 in the same row intersect at an angle of 60°.

[0042] In this way, the electrolyte in the tank can enter the liquid outlet pipe more uniformly. At the same time, since the angles of the first through holes on the liquid inlet pipe are opposite to the angles of the second through holes on the liquid outlet pipe, the high-concentration electrolyte can flow into the tank more quickly and come into more sufficient contact with the low-concentration electrolyte, thereby making the electrolyte concentration in the entire tank more uniform.

[0043] Specifically, a third through hole 32 is provided at the top of the liquid outlet pipe 3, and the third through hole 32 is located between the two columns of second through holes 31.

[0044] In this way, it not only speeds up the speed of the electrolyte entering the liquid outlet pipe, but also allows the electrolyte at more positions in the electrolyte tank to enter the liquid outlet pipe.

[0045] Specifically, the liquid inlet pipe 2 is sleeved with a mounting plate 23, and the mounting plate 23 is connected to the inner side wall of the tank 1.

[0046] Specifically, the bottom of the liquid outlet pipe 3 is installed at the bottom of the tank 1 through a limit seat 33. Among them, an arc-shaped groove for placing the liquid outlet pipe 3 is provided at the top of the limit seat 33.

[0047] Specifically, a plurality of liquid discharge holes 11 are formed in the side wall of the tank body 1, and a plugging device 12 is installed in the liquid discharge holes 11; wherein, the horizontal heights of the liquid discharge holes 11 are different.

[0048] In this way, the liquid level in the tank can be controlled as needed.

[0049] The applicant found that in the prior art, generally, the liquid leakage hole is set as an internal thread structure, and the plugging is realized by a plug. When replacing the electrolyte in the tank body, it is necessary to frequently disassemble the plug, resulting in wear of the internal thread of the liquid leakage hole. Therefore, the applicant designed the following structure:

[0050] The plugging device 12 includes a hollow cylinder 121, the outer side of the hollow cylinder 121 is connected to the liquid discharge hole 11, the end of the hollow cylinder 121 extends out of the tank body 1, and an annular disc 122 is sleeved on the end of the hollow cylinder 121. A plugging disc 123 is arranged on the side of the annular disc 122 facing away from the tank body 1; a screw hole 124 is formed in the annular disc 122, and a screw rod corresponding to the screw hole 124 is installed on the plugging disc 123.

[0051] During implementation, the size of the plugging disc 123 is designed to be able to block the port of the hollow cylinder 121.

[0052] In this way, the cooperation between the plugging disc and the hollow cylinder reduces the wear of the internal thread of the liquid leakage hole caused by frequently disassembling the plug when replacing the electrolyte in the tank body, and improves the service life of the tank body.

[0053] Specifically, a liquid leakage groove 13 is formed at the bottom of the inner cavity of the tank body 1, a liquid leakage hole 14 is formed in the liquid leakage groove 13, and a wire screw insert (not shown) is coaxially installed in the liquid leakage hole 14. The outer side of the wire screw insert is fixedly connected to the inner wall of the liquid leakage hole 14, and the inner side of the wire screw insert is used for detachably connecting with a plug (not shown).

[0054] In this way, a liquid leakage groove is arranged at the bottom of the tank body, which can better gather the electrolyte and flow to the outside through the liquid leakage hole. When replacing the liquid in the tank body, the whole liquid discharge process is smoother and more stable; at the same time, the cooperation between the wire screw insert and the plug reduces the wear of the internal thread of the liquid leakage hole caused by frequently disassembling the plug when replacing the electrolyte in the tank body, and improves the service life of the tank body.

[0055] The above embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made. These are all equivalent modifications and evolutions made to the above embodiments based on the essence of the present invention, and these all belong to the protection scope of the present invention.
