Description

Technical Field

[0001] The utility model relates to the technical field of electrolyte turnover barrels, in particular to a large-caliber hoopless high-sealing electrolyte turnover barrel. Background Art

[0002] As a packaging or storage container for lithium-ion battery electrolyte, the electrolyte barrel is generally protected by pressurized nitrogen to maintain the stability of the physical and chemical properties of the electrolyte for a long time. Traditional electrolyte barrels are generally provided with two joints and pipelines, namely an upper liquid level pipeline and a lower liquid level pipeline. The upper liquid level pipeline is shorter and generally located above the internal electrolyte liquid level, while the lower liquid level pipeline is longer and generally located above the electrolyte liquid level. Sealing valves are respectively arranged on the two joints. However, during long-term use, the slight wear of the valve core will cause the decline of the valve sealing performance, thus affecting the sealing effect. In addition, the sealing effect of domestic stainless steel metal valves at present cannot meet the sealing requirements for electrolyte storage. Therefore, it is necessary to purchase high-end foreign sealing valves. However, the price of high-end sealing valves is expensive, and enterprises usually use them on the packaging storage tanks for product sales. As a turnover barrel in the electrolyte production process, ordinary sealing valves are used to reduce costs. However, the sealing effect of ordinary sealing valves is poor, which will also affect the quality of the electrolyte. Therefore, it is necessary to design a novel low-cost electrolyte turnover barrel with high sealing performance. Content of the Utility Model

An upper part of the electrolyte turnover barrel main body is fixedly connected with a barrel top cover. The barrel top cover is located below the top end of the electrolyte turnover barrel main body. A tubular barrel neck extending upward is fixedly connected to the middle of the barrel top cover. An opening at the top end of the barrel neck forms a filling port. The adjusting screw is coaxial with the filling port. A limiting ring closely attached to the inner wall of the electrolyte turnover barrel main body is arranged on the top surface of the barrel top cover. A limiting groove is opened at the top end of the limiting ring. The lower edge of the top sealing cover is adapted to the limiting groove at the top end of the limiting ring.

DETAILED DESCRIPTION OF THE EMBODIMENTS Embodiment 1

[0016] Please refer to Figures 1-4, the present utility model provides a technical solution: a large-diameter hoopless high-sealing electrolyte turnover barrel, including an electrolyte turnover barrel main body 1. A symmetrically arranged pair of connecting plates 2 are fixedly connected to the outer edge of the top end of the electrolyte turnover barrel main body 1. A support column 3 extending vertically upward is fixedly connected to the two connecting plates 2. The tops of the two support columns 3 are connected by a horizontally arranged connecting plate 4. A vertically arranged adjusting screw 5 is threadedly connected to the middle of the connecting plate 4. The top end of the adjusting screw 5 is located above the connecting plate 4 and is fixedly connected with an adjusting turntable 6. The bottom end of the adjusting screw 5 is located below the connecting plate 4 and is fixedly connected with a top sealing cover 7. An auxiliary sealing plug 8 is fixedly connected to the inner bottom end of the top sealing cover 7. The auxiliary sealing plug 8 has elasticity. An upper part of the electrolyte turnover barrel main body 1 is fixedly connected with a barrel top cover 11. The barrel top cover 11 is located below the top end of the electrolyte turnover barrel main body 1. A tubular barrel neck 12 extending upward is fixedly connected to the middle of the barrel top cover 11. The top opening of the barrel neck 12 forms a filling port 13. The adjusting screw 5 is coaxial with the filling port 13. A limiting ring 9 closely attached to the inner wall of the electrolyte turnover barrel main body 1 is arranged on the top surface of the barrel top cover 11. A limiting groove 10 is opened at the top end of the limiting ring 9. The lower edge of the top sealing cover 7 is adapted to the limiting groove 10 at the top end of the limiting ring 9. The auxiliary sealing plug 8 is in interference fit with the filling port 13; a gas extraction auxiliary pipe 14 is fixedly connected to the top end of one side of the top sealing cover 7. A gas extraction control valve 15 is arranged at the top end of one side of the gas extraction auxiliary pipe 14. The gas extraction control valve 15 is located outside the barrel neck 12. The gas extraction auxiliary pipe 14 penetrates through the top end of the top sealing cover 7. The connection relationship between the gas extraction auxiliary pipe 14 and the top sealing cover 7 is a communication. The connection relationship between the auxiliary sealing plug 8 and the filling port 13 is an elastic sealing connection.

[0017] In the implementation scheme, by rotating the adjusting turntable 6 to adjust the position height of the adjusting screw 5 on the connecting plate 4, the sealing above the barrel top cover 11 is realized by directly inserting the top sealing cover 7 into the inside of the limiting groove 10. At the same time, the auxiliary sealing plug 8 will be inserted into the inside of the filling port 13. The auxiliary sealing plug 8 is elastically contracted by the filling port 13 to realize the sealing of the filling port 13. The adjusting screw 5 presses and adjusts the top sealing cover 7, which can increase the sealing stability between the top sealing cover 7 and the limiting groove 10 at the top end of the limiting ring 9.

[0018] In this embodiment, the gas extraction auxiliary pipe 14 is arranged to perform a gas extraction operation on the annular cavity between the top sealing cover 7 and the barrel neck 12, reducing the air inside the electrolyte turnover barrel main body 1. The negative pressure state inside the annular cavity forms a buffer cavity. Even if a small amount of external air flows into the annular cavity, it will not enter the inside of the electrolyte turnover barrel main body 1 through the barrel neck 12, thereby improving the storage quality of the device and avoiding the problem of gas contaminating the electrolyte. Of course, injecting a high-pressure protective gas into the annular cavity can also play the same role.

[0019] In this embodiment, it is also preferably fixedly connected with an anti-slip bottom pad 16 on the bottom surface of the electrolyte turnover bucket body 1, so as to effectively improve the placement stability of the electrolyte turnover bucket body 1 and avoid the phenomenon of tipping. The number of the anti-slip bottom pads 16 is 7. The materials of the 7 anti-slip bottom pads 16 are rubber materials. The 7 anti-slip bottom pads 16 are circularly distributed on the bottom surface of the electrolyte turnover bucket body 1.

[0020] In this embodiment, the connection relationship between the top sealing cover 7 and the limiting ring 9 is a movable snap connection.

[0021] The working principle of this embodiment is as follows: By providing the barrel neck 12, the top sealing cover 7 and the auxiliary sealing plug 8, an annular sealed space is formed outside the barrel neck 12. Users can evacuate or fill protective gas into this annular sealed space to form a buffer cavity for protecting the materials in the barrel. When the air extraction control valve 15 has a decline in sealing performance due to wear, the buffer cavity can effectively inhibit the external air from entering the barrel body through the barrel neck 12 and contaminating the materials. The large-diameter hoopless high-sealing electrolyte turnover bucket provided by the utility model has a simple structure, is convenient to use, has a low cost and good sealing performance, can meet the short-term storage and turnover of materials in the production process, and effectively solves the technical problem that the electrolyte turnover buckets used in the current production process cannot achieve low cost and high sealing performance.

[0022] The above embodiments only illustrate the principles and effects of the present invention and some applied embodiments, rather than limiting the present invention; it should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can be made, and these all belong to the protection scope of the present invention.
