Detailed implementation manners

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

[0030] The following combines the attached Figure 1 To the attached Figure 4 And specific embodiments to elaborate on the present invention in detail.

[0031] Such as Figures 1-4As shown in the figure, the utility model provides an electrolyte production device, which includes a barrel body 1. The barrel body 1 has an upper sealing plate 101. A gas phase port 2, a liquid phase port 3 and a solid feeding pipe 4 communicating with the barrel body 1 are arranged on the upper sealing plate 101. The lower end of the liquid phase port 3 is connected with a material rod 5. The material rod 5 extends to the bottom of the barrel body 1. The material rod 5 is used to add liquid materials into the barrel body 1. By extending the material rod 5 to the bottom of the barrel body 1, it can avoid the generation of bubbles during the free fall of the liquid materials, which affects the mixing effect of the solid materials and the liquid materials. A ball valve 6 is connected to the solid feeding pipe 4. The ball valve 6 has a closing member. Rotating the handle 7 on the ball valve 6 can make the closing member rotate in the ball valve 6 to realize the opening or closing of the ball valve 6. The upper opening of the ball valve 6 is connected with a flange cover plate 8. A replacement port 9 is arranged on the side of the ball valve 6. The replacement port 9 is located between the upper opening and the closing member of the ball valve 6. The replacement port 9 is used for gas replacement at the connection of the ball valve 6 to ensure that no air is mixed in during the feeding process. Similarly, on the one hand, the gas phase port 2 is used to introduce nitrogen into the barrel body 1, and on the other hand, it is used for gas replacement at the connection of the gas phase port 2 and the liquid phase port 3 to ensure that no air is mixed in during the liquid feeding process.

[0032] In some embodiments, the liquid phase port 3 and the gas phase port 2 are fixed on the upper sealing plate 101 through a flange 10. There are orifices on the upper sealing plate 101. The flange 10 is fixed on the orifices through bolts. The liquid phase port 3 and the gas phase port 2 are arranged on the flange 10 and are located above the orifices. A first quick connector 11 is connected to the liquid phase port 3, and a second quick connector 12 is connected to the gas phase port 2. The quick connection with the external pipeline is realized through the first quick connector 11 and the second quick connector 12.

[0033] In some embodiments, a third quick connector (not shown in the figure) is arranged on the replacement port 9. Through the third quick connector, it can be conveniently switched and connected with an external nitrogen pipeline or an external vacuum pipeline. The operation process can complete the pipeline switching by directly plugging and unplugging in a short time, which is time-saving and labor-saving.

[0034] In some embodiments, the material rod 5 is arranged obliquely from top to bottom. The material rod 5 has a discharge port, and the discharge port is an inclined port. In this application, the material rod 5 is arranged in an inclined structure, so that the liquid material flows downward along the inner wall of the material rod 5 during the falling process, reducing the impact force and avoiding the generation of bubbles. Setting the discharge port as an inclined port in this application can make there be a certain gap between the discharge port and the bottom of the barrel body 1, which is convenient for the liquid material to quickly enter or quickly discharge from the barrel body 1.

[0035] In some other embodiments, such as Figure 4As shown in the figure, the material rod 5 includes a vertical rod 501 and an arc rod 502 that is arc-transitionally connected to the lower end of the vertical rod 501. The vertical rod 501 is connected to the liquid phase port 3, and the arc rod 502 extends to the bottom of the barrel 1. Through the combined use of the vertical rod 501 and the arc rod 502 in this application, when discharging the finished electrolyte, it is transmitted through the arc rod 502 and the vertical rod 501 in sequence. The arc rod 502 can more effectively absorb the electrolyte remaining at the bottom of the barrel 1, thereby reducing the remaining electrolyte inside the barrel 1 and improving the utilization rate of the finished electrolyte in the barrel 1.

[0036] Specifically, the solid feeding pipe 4 of this application is fixed on the upper sealing plate 101 and is vertically arranged. The upper end of the solid feeding pipe 4 is provided with external threads, and the solid feeding pipe 4 is threadedly connected to the ball valve 6 through the external threads, and the threaded connection is sealed with an anti-corrosion sealing rubber part. While ensuring the seal, it avoids the corrosion of the sealing rubber part by the electrolyte.

[0037] In some embodiments, as Figure 1 shown, a plurality of universal wheels 13 are provided at the lower end of the barrel 1, and a locking structure is provided on the universal wheels 13. The electrolyte production device of this application can be flexibly moved through the universal wheels 13.

[0038] In a specific embodiment, an upper protective cover 14 is detachably connected above the barrel 1. The gas phase port 2, the liquid phase port 3, and the solid feeding pipe 4 are all located inside the upper protective cover 14. After the feeding is completed, the upper protective cover 14 can be covered and then moved to a rolling machine or an oscillator to reduce the possibility of the gas phase port 2, the liquid phase port 3, and the solid feeding pipe 4 contacting the outside; a handle hole 141 is provided on the side of the upper protective cover 14. Since the electrolyte production device of this application is small in size, the operator can carry it to a certain position through the handle hole 141.

[0039] In a specific embodiment, silicone gaskets are provided between the flange 10 and the barrel 1, and between the flange cover plate 8 and the ball valve 6 to ensure the sealing performance of the connection. At the same time, anti-corrosion sealing rubber parts are used for sealing at other threaded connections to ensure that the entire device is in a sealed state during the electrolyte production process and improve the quality of the electrolyte.

[0040] Specifically, a movable pressure gauge (not shown in the figure) is connected to the gas phase port 2. The pressure gauge is used to detect the pressure of nitrogen gas in the barrel to ensure that under a certain pressure, all the finished electrolyte in the barrel 1 can be discharged into the electrolyte container to be filled.

[0041] Specifically, the electrolyte production device of this application is made of stainless steel material.

[0042] The working principle of the present utility model is as follows: During the production of the electrolyte, the liquid material is added through the first quick connector 11 from the liquid phase port 3 and added to the bottom of the barrel body 1 along the material rod 5; after the liquid feeding is completed, solid feeding starts. First, open the flange cover plate 8 and connect the solid material barrel 15. Then, nitrogen gas is introduced and vacuum pumping is carried out through the replacement port 9. First, nitrogen gas is introduced, and then vacuum pumping is carried out after that. One cycle of introducing nitrogen gas and vacuum pumping is regarded as one replacement. The specific operation is as follows: Connect the third quick connector of the replacement port 9 to the external nitrogen gas pipeline to complete the nitrogen gas introduction operation; similarly, connect the third quick connector of the replacement port 9 to the external vacuum pipeline to complete the vacuum pumping operation. The time for vacuum pumping and nitrogen gas introduction is generally 30 seconds; after three replacements, open the ball valve 6. At this time, the solid material enters the barrel body 1 from the solid material barrel 15 through the solid feeding pipe 4. After the solid material is added, close the ball valve 6 and remove the solid material barrel 15; then, nitrogen gas is supplemented into the barrel body through the gas phase port 2 to 10 - 60 kPa, and the pressure value is read through the pressure gauge installed on the gas phase port 2. After the feeding is completed, place the electrolyte production device of the present application on a roller machine or an oscillator and shake it evenly to obtain the finished electrolyte. When using the finished electrolyte, the container to be filled with the electrolyte is connected to the first quick connector 11 through an external pipeline, nitrogen gas is supplemented from the gas phase port 2, and the finished electrolyte can be discharged from the liquid phase port and discharged into the container to be filled with the electrolyte through the external pipeline.

[0043] The above further describes the present utility model with the aid of specific embodiments. However, it should be understood that this specific description should not be construed as a limitation on the essence and scope of the present utility model. Various modifications made by those of ordinary skill in the art to the above embodiments after reading this specification all fall within the scope protected by the present utility model.
