Description

Technical Field

[0001] This utility model relates to the technical field of electrolyte storage and transportation equipment, and in particular to an electrolyte container that can be quickly filled. Background Technology

[0002] With the rapid development of the battery industry, the market demand for battery materials (positive electrode materials, negative electrode materials, electrolytes, etc.) has increased significantly. Early electrolyte packaging containers were mostly 50L, 100L, and 200L, with the 200L container being the mainstream for many years and the primary container for electrolyte storage and transportation. In recent years, with the development of the battery-powered vehicle and energy storage battery industries, the consumption of electrolyte has increased dramatically, leading to the emergence of larger 1000L ton containers, each containing approximately 1000kg of electrolyte. Currently, there are no unified industry standards for container design; most manufacturers create their containers based on their own needs, referencing previous 200L designs and components. Since battery manufacturers are the final users of the electrolyte, it is necessary to ensure compatibility between the connectors used in the packaging containers of different electrolyte manufacturers, ensuring that all electrolyte containers use the same connectors.

[0003] Generally, most electrolyte packaging containers have small inlet pipe diameters because they use the relatively mature Nitto connectors previously used on 200L containers. However, Nitto connectors have a circular cross-section, which has a small area and does not fully utilize the entire cross-section of the pipe, resulting in greater liquid flow resistance. While this is acceptable for 200L containers, it becomes more significant for 1000L ton containers, typically requiring 25 to 30 minutes to fill each container. Furthermore, these connectors require two hands to pull the male and female ends together, making automated connection and filling difficult and hindering efficiency improvements. Additionally, the inlet pipes and connectors have a short-term leakage of electrolyte during connection, which is detrimental to mitigating HSE risks.

[0004] Based on the above shortcomings, the inventors propose an electrolyte container that can be filled quickly. Utility Model Content

The inner diameter of the quick-connect connector is 15mm-80mm, and in this embodiment, the inner diameter of the quick-connect connector is 25mm. A shut-off valve (not shown in the figure) is installed on the quick-connect connector. The shut-off valve is a double flat-head dry valve.

The third end is used to connect to the electrolyte production container (not shown in the figure). The fourth end of the 25mm quick-connect connector and the second end of the straight-through inner tube N7 are connected by a threaded tightening method. The third end of the quick-connect connector is connected to the electrolyte production container through a hose to realize the quick disassembly and assembly of the quick-connect connector and the inner tube N7.

[0032] It should be noted that the shut-off valve and the double flat-head dry valve in this embodiment are both common valve components in the field, and their specific structures and working principles will not be described in detail here.

[0033] The upper end of the barrel 3 has an upper opening, and the lower end of the barrel 3 has a lower opening. The upper end cap 12 is sealed at the upper opening, and the lower end cap 1 is sealed at the lower opening, so that the inside of the barrel 3 forms a closed space to contain the electrolyte.

[0034] The inner tube N7 is directly connected to the upper end cap 1. That is, the upper end cap 1 is provided with a connection hole, and the first end of the inner tube N7 is detachably inserted into the connection hole. In other embodiments, the first end of the inner tube N7 can also be detachably inserted into the connection hole of the upper end cap 1 and detachably connected to at least one of the spray pipe N5, the gas phase pipe N1a,b and the liquid phase pipe N2a,b.

[0035] The top of the upper end cap is sequentially connected to the upper sealing gasket 8, the upper tank flange 9, and the upper flange cover 7. The center of the upper flange cover 7 is connected to the insertion pipe 6, which serves as the liquid phase pipe N2a,b and the spray pipe N5. The 360° spray cleaning ball 11 is installed inside the tank body 3. One end of the spray pipe N5 is used to connect to the cleaning liquid supply end, and the other end of the spray pipe N5 passes through the upper end cap 12 and connects to the 360° spray cleaning ball 11 to facilitate cleaning the inside of the tank body 3. One end of the gas phase pipe N1a,b passes through the upper end cap 12 and connects to the tank body 3. The other end of the gas phase pipe N1a,b is used to connect to the inert gas source to facilitate filling the tank body 3 with inert gas and protecting the electrolyte inside the tank body 3. One end of the liquid phase pipe N2a,b passes through the upper end cap 12 and connects to the tank body 3. The other end of the liquid phase pipe N2a,b is used to connect to the electrolyte access end to facilitate removing the electrolyte from the tank body 3.

[0036] The upper end cap is connected to the pressure gauge interface 4 and the exhaust valve interface 10 on the right side, serving as the pressure gauge port N3 and the exhaust valve port N4; the upper end cap 1 is connected downward to the barrel body 3, the barrel body 3 is connected downward to the lower end cap 12, and the lower end cap 12 is connected to the pipe 13, serving as the lower liquid outlet N6, which facilitates the use of electrolyte; the barrel body 3 is connected to the support leg 2, and the outer frame (not shown in the figure) is connected to the barrel body 3 and the support leg 2, which serves to fix the barrel body 3.

[0037] Compared to traditional Nitto connectors (4S+4P specification, inner diameter around 10mm), the 25mm quick-change connector and 25mm inner tube N7 have a larger orifice, providing excellent flow performance and improving filling efficiency.

[0038] Experimental tests showed that filling 1 ton of filtered electrolyte using Nitto connectors (4S+4P specification) took about 25 to 30 minutes. However, filling 1 ton of the same electrolyte using a dedicated filling assembly equipped with a 25mm inner diameter double flat-head dry valve took about 9 minutes, significantly reducing the filling time.

[0039] Furthermore, the valve of the injection component adopts a double flat-head dry valve, which makes it easier to achieve automated docking during connection. Simply rotate it a certain angle and push it in to connect and open the pipe to achieve connection. Conversely, the operation can disconnect and automatically lock the pipe. After the quick-connect connector is disconnected, there is less residual liquid on the surface, which is cleaner and effectively solves the problem of electrolyte leakage, thus improving safety.

[0040] The sealing gasket of this double flat-head dry valve is made of perfluoroether material, which is resistant to high temperature and corrosion, ensuring sealing performance. After the feed inlets are combined, the connection operation is convenient, and the subsequent cleaning workload is halved.

[0041] Example 2

[0042] The quick-connect fitting for the injection assembly can also be a quick-connect fitting with an inner diameter of 40mm. The inner tube N7 is a straight-through inner tube. The 40mm quick-connect fitting and the 40mm inner tube N7 are connected by a spiral snap-fit. The valve is a double flat-head dry valve. The sealing gasket is made of perfluoroether material and has a quick-connect fitting with an inner diameter of 40mm.

[0043] Tests showed that, under the same conditions, the filling time for one ton of electrolyte using this injection assembly was reduced to approximately 4 minutes. If the inner diameter of the electrolyte filling pipeline is increased accordingly, the flow resistance will decrease, and the filling time can be further reduced to 2-3 minutes, significantly lower than the filling speed of the traditional Nitto (4S+4P) connector.
