Description

Technical Field

[0001] The present invention relates to the technical field of electrolytes, and in particular to a waste battery electrolyte collection device and a use method thereof. Background Art

[0002] The electrolyte conducts ions between the positive and negative electrodes of lithium-ion batteries, ensuring their high voltage and high specific energy. Electrolytes are typically prepared under certain conditions and proportions using high-purity organic solvents, lithium electrolyte salts, and necessary additives. Lithium battery electrolytes are classified into three categories: liquid, solid, and viscous.

[0003] With the rapid development of new energy in my country, the recycling of used batteries has become an important emerging field. To recycle the electrolyte in used batteries, a used battery electrolyte collection device is generally required.

The notch collection assembly includes a first cutting module and a collection box. The conveying assembly conveys the square-shell battery through the first cutting module, thereby cutting a notch into the square-shell battery. This allows the electrolyte inside the square-shell battery to flow out and be collected by the collection box, thus achieving automatic collection of the electrolyte.

[0036] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific embodiments of the present invention are now described in detail with reference to the accompanying drawings. In the following description, it should be understood that the directions or positional relationships indicated by "front", "back", "up", "down", "left", "right", "longitudinal", "horizontal", "vertical", "horizontal", "top", "bottom", "inside", "outside", "head", "tail", etc. are based on the directions or positional relationships shown in the accompanying drawings and are constructed and operated in specific directions. They are only for the convenience of describing the technical solution and do not indicate that the devices or components referred to must have specific directions. Therefore, they should not be understood as limiting the present invention.

[0037] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0038] Please combine Figures 1 to 5 An embodiment of the present application provides an electrolyte collection device for waste batteries 30, including a transport mechanism 10 for transporting waste batteries 30 and a liquid collecting mechanism 20 arranged on one side of the transport mechanism 10, the liquid collecting mechanism 20 including a liquid collecting box 21, a liquid collecting pipe 22, a cutter 23, a drive assembly 24 and an elastic body 25.

[0039] Specifically, the liquid collection tank 21 is used to collect electrolyte flowing out of the used batteries 30. One end of the liquid collection pipe 22 is connected to the liquid collection tank 21, and the other end of the liquid collection pipe 22 extends toward the used batteries 30. A cutter 23 is coaxially mounted on the end of the liquid collection pipe 22 near the used batteries 30 and is connected to the interior of the liquid collection pipe 22. The end of the cutter 23 that extends toward the transport mechanism 10 is formed with a cutting end 23a for cutting the surface of the used batteries 30, and a storage space a is formed between the cutter 23 and the liquid collection pipe 22. The drive assembly 24 is used to rotate the cutter 23, thereby driving the cutter end 23a to rotate and cut the surface of the used battery 30 to form a liquid outlet b. The elastic body 25 is housed within the storage space. The elastic body 25 has a plurality of annularly spaced protrusions 25a disposed on the surface of the used battery 30. A through hole 25b is defined in the middle of the elastic body 25. The through hole 25b is used to direct electrolyte flowing out of the liquid outlet to the liquid collection pipe. When the elastic body 25 is pushed out of the storage space a, it deforms in a first direction to block the liquid outlet b.

[0040] Here, it should be noted that the "first direction" mentioned above may refer to the axial direction of the collecting pipe 22 (refer to Figure 1 in the X direction).

[0041] For example, the transport mechanism 10 mainly transports the used batteries 30 to be recycled to the liquid collection mechanism 20 for electrolyte recovery, and then moves the used batteries 30 after the electrolyte has been collected to a designated location for placement, so as to improve the automatic collection operation, reduce manual participation, and help improve the collection efficiency. To this end, the transport mechanism 10 can adopt the transport components used for transporting products in the prior art, or can adopt the transport mechanism 10 with the specific structure in the following embodiment, without limitation. In addition, it should be noted that when the used battery 30 moves to a position directly opposite the cutter 23, the cutter end 23a contacts the bottom surface of the used battery 30, which can directly drive the cutter 23 to rotate and cut, which helps to accelerate the efficiency of electrolyte collection.

[0042] For example, the drive assembly 24 can be a combination of a motor and a synchronous belt, with the motor driving the synchronous belt to operate. This allows the synchronous belt to rotate the cutter 23, which in turn drives the cutter end 23a to rotate, thereby cutting the bottom surface of the used battery 30 to form the liquid flow port b. This achieves automatic cutting of the used battery 30 without manual operation. Those skilled in the art will appreciate that the above drive assembly 24 is merely an example and is not limited thereto. Other components known in the art that can drive the cutter 23 to rotate may also be used.

[0043] For example, the elastic body 25 is a component made of an elastic material that deforms only in a first direction (i.e., the radial direction of the manifold 22) and does not deform in the axial direction of the manifold 22. Therefore, when the elastic body 25 is housed in the housing space a, the elastic body 25 is in a compressed state. When the elastic body 25 is pushed out of the housing space a, the elastic body 25 extends into the liquid flow port. The compressed elastic body 25 deforms and stretches only in the first direction until the ends of the elastic body 25 extend to abut against the cutter 23, allowing the elastic body 25 to be inserted into the liquid flow port b, thereby sealing the liquid flow port b formed by cutting and preventing gas generated by the electrolyte from escaping from the liquid flow port b into the air and causing air pollution. In addition, when the elastic body 25 extends into the liquid flow port b to seal it, the protrusion 25a always contacts the cut portion and pushes it into the interior of the used battery 30. At this time, the electrolyte inside the used battery 30 flows from the gap between the adjacent protrusions 25a to the through hole 25b and enters the liquid collecting pipe 22.

[0044] Exemplarily, the connection between the collecting pipe 22 and the collecting tank 21 needs to be sealed to prevent the odor of the electrolyte flowing into the collecting tank 21 from being emitted into the air from the connection between the collecting pipe 22 and the collecting tank 21, thereby causing air pollution.

[0045] For example, in order to speed up the flow of electrolyte in the waste battery 30 into the collecting tank 21, before starting to collect the electrolyte, a vacuum device can be used to extract the gas in the collecting tank 21 to reduce the pressure in the collecting tank 21, thereby speeding up the flow of electrolyte into the collecting tank 21.

[0046] The electrolyte collection device for used batteries 30 based on the above-mentioned technical features utilizes a drive assembly 24 to rotate the cutter 23, causing the cutter end 23a to cut the surface of the used battery 30 to form a liquid flow port b. The elastic body 25 is then pushed out of the storage space a, causing the elastic body 25 to deform in a first direction and extend to block the liquid flow port b, effectively preventing gases generated by the electrolyte from escaping from the liquid flow port into the air and causing air pollution. Simultaneously, as the elastic body 25 extends into the liquid flow port to seal it, the raised portion 25a pushes the cut portion into the interior of the used battery 30, preventing the cut portion from blocking the through-hole 25b and preventing the electrolyte from flowing into the collection pipe 22 and the collection tank 21, thereby ensuring the normal flow of the electrolyte into the collection tank 21.

[0047] After the cutter end 23a cuts the bottom of the used battery 30 to form the liquid outlet b, the elastic body 25 needs to be pushed out of the storage space a. By utilizing the elastic body 25's ability to deform in the first direction, the elastic body 25 extends to block the liquid outlet. Therefore, to achieve a better sealing effect of the elastic body 25 on the liquid outlet, in one embodiment, after the elastic body 25 deforms in the first direction, the diameter of the elastic body 25 is greater than the diameter of the cutter 23.

[0048] For example, if the elastic body 25 deforms in the first direction so that its diameter is smaller than the diameter of the cutter 23, and the diameter of the elastic body 25 is smaller than the diameter of the liquid outlet, a gap will form between the elastic body 25 and the liquid outlet, which could easily cause electrolyte odor to escape, polluting the air and affecting human health. If the deformed diameter of the elastic body 25 is not too large, it will be difficult to store the elastic body 25 in the storage space a, increasing operational difficulties.

[0049] In one embodiment, when the elastic body 25 is received in the receiving cavity, the end surface of the protrusion 25 a away from the end of the elastic body 25 is lower than the end surface of the cutting end 23 a .

[0050] For example, when the transport mechanism 10 transports the used battery 30 to a position opposite the cutter 23, the cutter end 23a contacts the bottom surface of the used battery 30, while the raised portion 25a provided on the elastic body 25 does not contact the bottom surface of the used battery 30, so that the cutter end 23a can be driven to cut the bottom surface of the used battery 30 by driving the cutter 23 to rotate, thereby ensuring normal cutting operation; if the end surface of the convex ball portion is higher than the end surface of the cutter end 23a, the bottom surface of the used battery 30 will only contact the raised portion 25a, and the cutter end 23a will not be able to contact the bottom surface of the used battery 30, thereby making it impossible to directly cut the bottom surface of the used battery 30, resulting in the electrolyte being unable to flow into the collecting tank 21 for collection.

[0051] Reference Figure 3 and Figure 4 In one embodiment, the drive assembly 24 includes a power member 241, a driving gear 242, and a driven gear 243. The power member 241 is disposed on one side of the cutter 23, and the power output end of the power member 241 is connected to the driving gear 242. The driven gear 243 is sleeved on the cutter 23 and meshed with the driving gear 242.

[0052] For example, the "power part 241" can be a motor, and the driving gear 242 is connected to the power output end of the motor, and the driven gear 243 engaged with the driving gear 242 is sleeved on the cutter 23, so that when the motor drives the driving gear 242, the driven gear 243 is driven to rotate, thereby driving the cutter 23 to rotate, thereby realizing cutting the bottom surface of the waste battery 30 to form a liquid flow outlet. The structure is simple, the operation is convenient, and no manual participation is required.

[0053] In one embodiment, an ejection assembly 26 is further included, which includes a pusher 261 and a push ring 262. The push ring 262 is sleeved on the liquid collecting pipe 22 and is located in the accommodating space. The pusher 261 is configured to drive the push ring 262 to move axially along the liquid collecting pipe 22 to push the elastomer 25 out of the storage space a.

[0054] For example, the pusher 261 drives the push ring 262 to move axially along the liquid collecting tube 22, thereby pushing the elastic body 25 out of the storage space a or pulling the elastic body 25 back into the storage space a. To this end, the end of the push ring 262 away from the elastic body 25 needs to be fixedly connected to the push of the pusher 261, and the end of the push ring 262 close to the elastic body 25 needs to be fixedly connected to the elastic body 25, so that the pusher 261, the push ring 262, and the elastic body 25 are connected to form a whole. This ensures that after the elastic body 25 is pushed out of the storage space a, it can be pulled back into the storage space a by the pulling action of the push ring 262, ensuring that the flow port b of the next used battery can be blocked.

[0055] Reference Figure 3 In this embodiment, the pushing member 261 can be a push rod, which is set in a direction perpendicular to the liquid collecting pipe 22, and the end of the push rod extending toward the liquid collecting pipe 22 is connected to the end of the push ring 262 away from the elastomer 25. When the elastomer 25 needs to be pushed out from the storage space a, the push rod is pushed in a direction close to the elastomer 25 so that the push ring 262 is pushed close to the transport mechanism 10, thereby pushing the elastomer 25 out of the storage space a; when the elastomer 25 needs to be retracted into the storage space a, the push rod is pushed in a direction away from the elastomer 25 so that the push ring is pulled away from the liquid flow port, thereby pulling the elastomer back into the storage space a.

[0056] Reference Figure 4 In other embodiments, the pusher 261 can be a telescopic cylinder, with the piston rod of the telescopic cylinder being extended and retracted to move the push ring along the axial direction of the liquid collecting tube 22, thereby moving the push ring 262 toward or away from the elastic body 25. To push the elastic body 25 out of the receiving space a, the piston rod of the telescopic cylinder is controlled to extend to push the push ring 262 toward the elastic body 25 until the elastic body 25 is pushed out of the receiving space a. To retract the elastic body 25 into the receiving space a, the piston rod of the telescopic cylinder is controlled to retract to pull the push ring 262 away from the liquid outlet, causing the elastic body to be pulled and compressed back into the receiving space a. This simple structure and convenient operation are achieved. Furthermore, the cutter end 23a is configured as an inclined surface, which facilitates the retraction of the elastic body 25 into the receiving space a.

[0057] In one embodiment, the ejection assembly 26 further includes a connecting member 263, which is located between the pushing member 261 and the push ring 262. The connecting member 263 is connected to the end of the push ring 262 away from the elastic body 25, and the end of the connecting member 263 away from the push ring 262 is provided with a notch for fixed connection with the pushing end of the pushing member 261. In this way, by providing the connecting member 263 between the pushing member 261 and the push ring 262 and providing the notch at the end of the connecting member 263 away from the push ring 262, the pushing end of the pushing member 261 can be snapped into the notch and fixed to the connecting member, and the connecting member is fixedly connected to the push ring, so that the pushing member, the connecting member and the push ring are connected to form a whole, ensuring that when the pushing member pushes, the connecting member and the push ring can generate corresponding movement, thereby avoiding relative sliding that affects the pushing effect.

[0058] To prevent the cutter 23 from rotating the collection pipe 22, in one embodiment, a bearing 28 is provided between the cutter 23 and the collection pipe 22 to prevent the collection pipe 22 from rotating during the rotation of the cutter 23. This allows the cutter 23 to rotate relative to the bearing 28 without rotating the collection pipe 22.

[0059] In one embodiment, a pull-back member 27 is further included. The pull-back member 27 is wrapped around the outer peripheral surface of the end of the collecting pipe 22 away from the collecting tank 21. The pull-back member 27 is located in the accommodating space, and one end of the pull-back member 27 is fixedly connected to the elastomer 25, and the other end of the pull-back member 27 is fixedly connected to the bearing 28.

[0060] For example, the pull-back member 27 is used to pull the elastic body 25, which has been pushed into the interior of the used battery 30, back to the liquid outlet b to block the outlet and ensure that the elastic body 25 can completely block the outlet. It should be noted that the pull-back member 27 can be a spring or other elastic component known in the art, and this is not limited to this.

[0061] It should be noted that in order to ensure that the elastic body 25 is pulled back into the accommodation space a, it is necessary to ensure that one end of the pullback member 27 is fixedly connected to the elastic body 25, and the other end of the pullback member 27 is fixedly connected to the bearing 28. For example, if one end of the pullback member 27 is only connected to the elastic body 25, and the other end of the pullback member 27 is only in contact with the bearing 28, then when the push member 261 drives the push ring 262 to move and push the elastic body 25 out, the pullback member 27 will move along with the elastic body 25, making it impossible for the pullback member 27 to generate tension, resulting in no pulling force being applied to the elastic body 25, and thus preventing the elastic body 25 from being pulled back to the liquid flow port b for blocking.

[0062] In order to facilitate the understanding of the process of the elastic body extending and pulling back in the above embodiment, the following Figure 5 The process is described as follows:

[0063] When the bottom surface of the used battery is cut by the cutting end 23a of the cutter 23, the protrusion 25a provided on the elastic body 25 is always in contact with the cut portion, so that the pushing member 261 drives the pushing ring 262 to move in the direction close to the used battery, so that the elastic body 25 compressed in the storage space a is extended, so that the cut portion is pushed out and enters the interior of the used battery. At this time, the extended elastic body 25 is deformed only in the first direction (the radial direction of the collecting tube 22), and the cutter 23 is withdrawn downward to the outside of the used battery shell, so that the two ends of the extended elastic body 25 abut against the side walls of the liquid flow port b, while the unextended part of the elastic body 25 is still located in the accommodation space a, thereby ensuring that the electrolyte inside the used battery 30 only flows from the gap between the adjacent protrusions 25a to the through hole 25b and enters the collecting tube 22, and cannot flow out from the gap between the elastic body 25 and the liquid flow port b.

[0064] When the electrolyte in the used battery is recovered, the push member 261 is used to drive the push ring 262 to move away from the used battery, so that the push ring 262 applies a pulling force to the elastic body 25, and then the protruding part of the elastic body 25 is pulled back into the accommodating space b. At this time, the cut part follows the movement of the elastic body 25 and moves down to the liquid flow outlet, thereby blocking the liquid flow outlet.

[0065] In one embodiment, the liquid collecting pipe 22 includes a first tube body 221 and a second tube body 222, one end of the second tube body 222 is connected to one end of the first tube body 221, and the other end of the second tube body 222 is connected to the liquid collecting tank 21, and one end of the first tube body 221 away from the second tube body 222 extends toward the transport mechanism 10, the cutter 23 is sleeved on the first tube body 221, and the pull-back member 27 is wrapped around the outer peripheral surface of the first tube body 221.

[0066] For example, the manifold 22 is formed by combining a second tube body 222 with a first tube body 221. The second tube body 222 is used to connect to the manifold 21, while the first tube body 221 is used to receive the cutter 23 and the push ring 262. This ensures that the cutter 23 and the push ring 262 have sufficient rigidity when they are received by the manifold 22. Furthermore, the first tube body 221 can be made of a rigid material (e.g., a copper alloy). Those skilled in the art will appreciate that the above-described manifold 22 is merely an example and is not intended to be limiting.

[0067] In one embodiment, the device further includes a housing 40 located on the same side as the liquid collection tank 21. The housing 40 is positioned above the liquid collection tank 21. The end of the liquid collection pipe 22, facing away from the liquid collection tank 21, extends through the housing 40. The cutter 23 and the drive assembly 24 are both housed within the housing 40. An opening is defined on the side of the housing 40 facing away from the liquid collection tank 21, through which the cutter 23 is exposed. Thus, the housing 40 houses both the cutter 23 and the drive assembly 24. When the electrolyte is not being collected, the opening can be covered with a cover to prevent foreign matter from entering the cutter end 23a, the liquid collection pipe 22, or the liquid collection tank 21.

[0068] In one embodiment, the transport mechanism 10 includes a driving member 11, a driving shaft 12, a driven shaft 13 and a transport belt 14. The driving shaft 12 and the driven shaft 13 are arranged opposite to each other and spaced apart. The transport belt 14 is arranged between the driving shaft 12 and the driven shaft 13. The power output end of the driving member 11 is connected to one end of the driving shaft 12 for driving the driving shaft 12 to rotate, thereby driving the transport belt 14 to operate. The liquid collection mechanism 20 is arranged below the transport belt 14.

[0069] For example, the “driving member 11 ” mentioned above may be a motor, or other power components that can drive the driving shaft 12 to rotate, and this is not limited.

[0070] In this embodiment, when the used batteries 30 to be collected are placed on the conveyor belt 14, the driving member 11 drives the driving shaft 12 to rotate. Since the conveyor belt 14 is provided between the driving shaft 12 and the driven shaft 13, the conveyor belt 14 is driven to move, thereby realizing automatic transportation of the used batteries 30 from one side to the other side, which helps to reduce labor intensity.

[0071] In addition, it should be noted that in order to detect whether the waste batteries 30 located on the conveyor belt 14 have moved, the cutting area corresponding to the cutter end 23a can be used in combination with the detection parts in the prior art (such as photoelectric sensor lines, contact sensors, etc.). For details, please refer to the part about the detection parts in the prior art, and there is no limitation on this.

[0072] The present disclosure also provides a method for using the electrolyte collection device for used batteries 30. The method uses the electrolyte collection device for used batteries 30 of the above embodiment, and includes the following steps:

[0073] S100: Place the used battery 30 on the transport mechanism 10 to move the used battery 30 along the first direction until the used battery 30 moves to a position facing the cutter end 23a, and then the transport mechanism 10 stops operating.

[0074] For example, the waste batteries 30 can be placed on the transport mechanism 10 in an automatic manner, for example, a robot is used to clamp the waste batteries 30 and automatically place them on the transport mechanism 10, eliminating the need for manual placement, thereby reducing labor intensity.

[0075] S200 , driving the cutter 23 to rotate via the driving assembly 24 so that the cutter end 23 a cuts the surface of the waste battery 30 to form a liquid flow outlet.

[0076] S300, drive the push ring 262 along the axial direction of the liquid collecting pipe 22 by the pushing member 261 to approach the elastomer 25, so that the elastomer 25 is pushed out from the storage space a, and then the elastomer 25 is deformed along the first direction to block the liquid outlet, and the protrusion 25a lifts the cut part of the shell 40, so that the electrolyte flows from the through hole 25b to the liquid collecting pipe 22 and enters the liquid collecting tank 21 for collection.

[0077] S400: After the electrolyte in the used battery 30 has completely flowed into the liquid collecting tank 21, the transport mechanism 10 is restarted to move the used battery 30 with the electrolyte collected to a designated location for placement.

[0078] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
