[0045] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0046] Example 1

[0047] like Figure 1 , Figure 2 As shown, the waste lithium battery storage device for lithium battery recycling includes: an outer shell 10; an exhaust system, the exhaust system includes an air inlet pipe 21 and an air outlet pipe 22 that are connected to the inside of the outer shell 10, and an exhaust pump 23 is provided on the air outlet pipe 22; when the device is used for storing waste lithium batteries, the air inlet pipe 21 is connected to the gas supply pipeline, and the air outlet pipe 22 is connected to the gas collection pipeline. When used for mobile transportation, an adsorption device, such as activated carbon, can be provided at the air outlet of the air outlet pipe 22 to avoid the emission of harmful gases.

[0048] A partition 30 is arranged inside the outer shell 10, and the partition 30 divides the interior of the outer shell 10 into a battery storage chamber 32 and an electrolyte collection chamber 33 distributed vertically. A battery 60 is placed inside the battery storage chamber 32, and a bottle body 70 is placed inside the electrolyte collection chamber 33. There is a gap between the bottle body 70 and the inner wall of the electrolyte collection chamber 33. A liquid hole is opened in the middle of the partition 30 corresponding to the battery 60, and an air hole 31 is opened on the edge of the partition 30. The air hole 31 connects the battery storage chamber 32 and the electrolyte collection chamber 33.

[0049] In the waste lithium battery storage device for lithium battery recycling in the present technical solution, the battery 60 is placed on the partition 30 inside the battery storage chamber 32, and the bottle body 70 is placed inside the electrolyte collection chamber 33 and is located directly below the battery 60. The electrolyte leaked from the battery 60 flows through the liquid hole to the inside of the bottle body 70 for collection. The flammable gas evacuation path formed by the air inlet pipe 21, the battery storage chamber 32, the air hole 31, the electrolyte collection chamber 33 and the air outlet pipe 22 evacuates the flammable gas formed by the volatilization of the electrolyte, and collects and treats the electrolyte and the flammable gas formed by the volatilization of the electrolyte.

[0050] In the technical solution, the electrolyte leaked from the battery 60 is collected inside the bottle body 70 through the liquid hole, thereby reducing the distribution area of ​​the leaked electrolyte and reducing the possibility of the electrolyte volatilizing to form flammable gas. On the other hand, the flammable gas that has volatilized is extracted from the outer shell 10 by the exhaust system and replenished with new gas, thereby avoiding the situation where a large amount of flammable gas accumulates in a small space and causes an explosion.

[0051] At the same time, the bottle body 70 is used to collect the electrolyte, so that the leaked electrolyte is isolated from flammable items, such as fire, gasoline, alcohol, etc., to ensure the safety of the entire device; the waste lithium battery storage device for lithium battery recycling in the present technical solution is used for the storage of waste lithium batteries in lithium battery recycling, especially batteries with explosion risks due to electrolyte leakage. The storage device of the present technical solution can be used for fixed storage and mobile transportation of lithium batteries.

[0052] As a more specific solution of this technical solution, Figure 1 , Figure 2 As shown, the air inlet pipe 21 is arranged at the upper part of the outer shell 10, corresponding to the upper end of the battery 60. When the exhaust system is in operation, the gas introduced through the air inlet pipe 21 directly acts on the battery 60, taking away the flammable gas near the battery 60, reducing the possibility of detonating the battery 60. At the same time, the introduced gas has a pressing force on the battery 60, improving the stability of the position of the battery 60.

[0053] The air outlet pipe 22 is arranged at the lower part of the outer shell 10, that is, the air exhaust pump 23 is located at the lower part of the device, which increases the mass of the lower part of the device, lowers the center of gravity of the device, ensures the stability of the device, and thus ensures the safety of the device.

[0054] The outlet position of the outlet pipe 22 is provided with an air inlet pipe 24, which dilutes the flammable gas discharged from the outlet pipe 22 to reduce the possibility of explosion of the flammable gas. The gas introduced by the air inlet pipe 1 21 and the air inlet pipe 2 24 is oxygen-free air with constant temperature and humidity. The introduced gas is oxygen-free, and the interior of the outer shell 10 is set as an oxygen-free space, so that the flammable gas cannot contact with oxygen, reducing the possibility of explosion; the introduced gas is set as a constant temperature setting, so that the interior of the outer shell 10 is kept at a constant temperature to avoid high or low temperature environments; the introduced gas is set as a constant humidity setting to avoid a humid environment inside the outer shell 10, and to avoid the situation where the lithium salt in the electrolyte is hydrolyzed in a humid environment.

[0055] In order to further improve the safety of the waste lithium battery storage device for lithium battery recycling during use, the present application has made improvements on the stability of the battery 60 and the bottle body 70. Specifically, a battery positioning member 40 is provided for the battery 60, and a bottle body positioning member 50 is provided for the bottle body 70. The provision of the battery positioning member 40 and the bottle body positioning member 50 enables the present device to have greater advantages in the mobile transportation of waste batteries. Of course, the stability of the battery 60 and the bottle body 70 can also be ensured in fixed storage, thereby ensuring safe storage.

[0056] like Figure 1 , Figure 2As shown, a bottle body positioning member 50 is provided inside the electrolyte collection chamber 33, and the bottle body positioning member 50 includes an outer cylinder 51 connected to the bottom wall of the electrolyte collection chamber 33, and a bottom plate 52 slidingly matched with the inner wall of the outer cylinder 51 in the up and down directions, and a spring 53 is connected between the bottom plate 52 and the outer cylinder 51; the spring 53 is arranged so that when the bottle body 70 is placed inside the outer cylinder 51 and on the bottom plate 52, its upper end contacts the lower end surface of the partition 30.

[0057] The setting of the bottle positioning member 50 in the present technical solution is as follows: 1. The bottle body 70 is limited inside the outer cylinder 51 to ensure the stability of the position of the bottle body 70, avoid incomplete collection of the electrolyte due to the movement of the bottle body 70, and avoid sparks generated by friction during the movement of the bottle body 70 and contact with flammable gases, thereby ensuring safety; 2. The setting of the spring 53 can reduce the shock of the bottle body 70 to ensure the stability of the bottle body 70, and at the same time make the upper end of the bottle body 70 contact with the lower end surface of the partition 30, thereby reducing the leakage area of ​​the electrolyte and the volatilization amount of the flammable gas; 3. The upper end of the bottle body 70 contacts with the lower end surface of the partition 30 to support the partition 30 and increase the strength of the partition 30.

[0058] like Figure 1 , Figure 2 , Figure 3 As shown, a battery positioning member 40 is disposed inside the battery storage chamber 32, and the battery positioning member 40 includes an outer tube body 41 connected to the upper end of the partition 30, wherein the liquid hole is located inside the outer tube body 41, and the air hole 31 is located outside the outer tube body 41;

[0059] A plurality of groups of baffles 46 are arranged inside the outer tube body 41. Through holes may be opened on the baffles 46 to facilitate the contact between the battery 60 and the introduced gas. The number of baffles 46 in each group is set to be multiple, and a hinge 47 is arranged between every two adjacent baffles 46 in a group, so that the multiple baffles 46 form a baffle chain, wherein the hinge 47 allows every two adjacent baffles 46 to be changed and fixed at any angle, and the position of one of the baffles 46 located at the end of the baffle chain is fixed.

[0060] When positioning the battery 60, the battery 60 is placed at the upper end of the partition 30 and inside the outer tube 41. By adjusting the angle between two adjacent baffles 46, the baffle 46 forms a first horizontal section A with a fixed end position, a second longitudinal section B that fits the outer wall of the battery 60, a third inclined section C that supports the second longitudinal section B, and a fourth longitudinal section D with a fixed position.

[0061] The arrangement of the battery positioning member 40 in the present technical solution confines the battery 60 inside the outer tube body 41, thereby ensuring the stability of the position of the battery 60, avoiding the situation where the battery 60 moves and generates sparks due to friction, and contacts with flammable gases, thereby ensuring safety; the battery positioning member 40 fixes the battery 60 by acting on the side of the battery 60, and the compression force generated on the battery 60 in the exhaust system cooperates with the partition 30 to fix the battery 60 by acting on the upper and lower directions of the battery 60. The combination of the two has a good fixing effect and a strong stability of the battery 60.

[0062] In the battery positioning member 40, the second longitudinal section B is fitted with the outer wall of the battery 60, and the first transverse section A and the third inclined section C support the second longitudinal section B. The baffle chain is folded to fix the battery 60. 1. The baffle chain is fitted with the outer wall of the battery 60, and the surface contact with the battery 60 is evenly stressed to avoid concentrated force and mechanical damage to the battery 60. 2. The upper and lower parts of the battery 60 can be fixed, and the stability is strong. The outer tube body 41 does not need a high height, which is convenient for placing the battery 60 in the outer tube body 41 or taking the battery 60 out of the outer tube body 41. 3. The folding length can be selected according to the specifications of the battery 60 to increase the scope of application.

[0063] like Figure 1 , Figure 2 , Figure 3 As shown, a stop block 1 42 and a stop block 2 43 are also provided inside the outer tube body 41 in the vertical direction, wherein a baffle 46 located at the end of the baffle chain is connected to the stop block 1 42, and both the stop block 1 42 and the stop block 2 43 are rotatably engaged with a screw rod 44, which passes through the outer tube body 41 and is threadedly engaged therewith, and both the stop block 1 42 and the stop block 2 43 are provided with a limit plate 45, which movably passes through the outer tube body 41.

[0064] On the premise that the limit plate 45 is movable through the outer tube body 41, the screw 44 is rotated, and the screw 44 drives the block 1 42 and the block 2 43 to move in the left and right directions. When the battery 60 is fixed, the block 1 42 and the block 2 43 are adjusted according to the positions of the first horizontal section A and the fourth vertical section D. The first horizontal section A is connected to the block 1 42, and the fourth vertical section D is in contact with the block 2 43, so that the second vertical section B is completely in contact with the outer wall of the battery 60 to ensure the positioning accuracy.

[0065] To solve the problem that each two adjacent baffles 46 are changed and fixed at any angle, as Figure 3 , Figure 4As shown, the hinge 47 includes a ring 1 471 and a ring 2 472 arranged on both sides of the baffle 46, and the ring 1 471 and the ring 2 472 on the two adjacent baffles 46 are rotatably matched with the same center sleeve 473 to realize the rotational matching setting between the two adjacent baffles 46; the cavity of the center sleeve 473 is threaded with a bolt 475, and the bolt 475 is provided with a platform 476 corresponding to the ring 1 471 and the ring 2 472 respectively, and the platform 476 is abutted against a rod body 474, and the movable end of the rod body 474 movably passes through the center sleeve 473 and abuts against the inner circle side wall of the ring 1 471 and the ring 2 472.

[0066] After the two adjacent baffles 46 are adjusted to a suitable angle, the bolt 475 is rotated to move it toward the inside of the central sleeve 473, and the platform 476 abuts against the rod 474, driving the rod 474 to abut against the inner circles of the ring 1 471 and the ring 2 472, thereby completing the fixation of the position between the two adjacent baffles 46.

[0067] In order to improve the convenience of the device during use, combined with the need to collect the electrolyte and evacuate the volatile flammable gas in this application, the outer shell 10 is set to a multi-layer split structure, specifically, as follows: Figure 1 , Figure 5 , Figure 6 As shown, the outer shell 10 includes an upper shell 11, a middle shell 12 and a lower shell 13 distributed in the vertical direction. A sealing ring can be set between the upper shell 11, the middle shell 12 and the lower shell 13 to prevent gas leakage. The air inlet pipe 21 is set on the upper shell 11, and the air outlet pipe 22 is set on the lower shell 13;

[0068] The lower end of the upper shell 11, the upper and lower ends of the middle shell 12, and the upper end of the lower shell 13 all extend radially outward to form a receiving plate 14. The receiving plates 14 at the lower end of the upper shell 11 and the upper end of the middle shell 12, and the receiving plates 14 between the lower end of the middle shell 12 and the upper end of the lower shell 13 are all fixed by fixing members 15.

[0069] When the waste lithium battery storage device for lithium battery recycling in the present technical solution is used, the bottle body 70 is first placed in the bottle body positioning member 50 in the lower shell 13, the middle shell 12 and the lower shell 13 are connected, the battery 60 is placed in the battery positioning member 40 in the middle shell 12, and the upper shell 11 and the middle shell 12 are connected. The operation is simple and easy to use.

[0070] like Figure 1 , Figure 5 As shown, a second positioning plate 121 is provided at the lower end of the middle shell 12, and the second positioning plate 121 is inserted into the interior of the lower shell 13. The upper end of the second positioning plate 121 forms a lap joint, and the partition 30 is placed at the position of the lap joint; a positioning plate 111 is provided at the lower end of the upper shell 11, and the positioning plate 111 is inserted into the interior of the middle shell 12 and abuts against the upper end of the partition 30.

[0071] In this technical solution, the partition 30 is stably assembled in the middle shell 12 by the overlapping portion at the upper end of the positioning plate 2 121 and the clamping cooperation of the positioning plate 1 111. The operation is simple, and the detachable setting of the partition 30 facilitates the cleaning of the electrolyte flowing through the partition 30.

[0072] like Figure 5 , Figure 6 , Figure 7 As shown, a notch 141 is provided at a position of the receiving plate 14 corresponding to the fixing member 15 ; the fixing member 15 is assembled in the notch 141 to increase the contact area and improve the fixing effect.

[0073] The fixing member 15 includes a clamping column 151 and a clamping column 153. A cavity 152 is opened at one end of the clamping column 151, and the clamping column 153 is inserted into the interior of the cavity 152, and a spring 154 is arranged between the two. The ends away from the clamping column 151 and the clamping column 153 are both arranged as large heads, and the receiving plate 14 is located between the large heads of the clamping column 151 and the clamping column 153.

[0074] When the receiving plate 14 is fixed by the fixing part 15, the clamping column 1 151 and the clamping column 2 153 are controlled to move away, and the fixing part 15 is placed in the slot 141. The big ends of the clamping column 151 and the clamping column 2 153 are respectively located at the upper and lower parts of the receiving plate 14. Under the action of the spring 2 154, the big ends of the clamping column 151 and the clamping column 2 153 complete the rapid clamping and fixing of the receiving plate 14, saving operation time and reducing the risk of explosion.

[0075] To further ensure the fixing effect of the fixing member 15, as Figure 7 As shown, the fixing member 15 also includes a thumb screw 155. The thumb screw 155 penetrates through the second clamping column 153 and then threads with the cavity 152. The thumb end of the thumb screw 155 cooperates with the thumb end of the second clamping column 153. After the thumb ends of the first clamping column 151 and the second clamping column 153 clamp the receiving plate 14, the thumb screw 155 is threadedly connected with the cavity 152 and the thumb screw 155 is continuously rotated until the thumb end of the thumb screw 155 is in close contact with the thumb end of the second clamping column 153. The thumb ends of the first clamping column 151 and the second clamping column 153 tightly clamp the receiving plate 14. The thumb screw 155 is set to be locked after the elastic clamping of the receiving plate 14 is completed to ensure the fixing effect.

[0076] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
