Description

Technical Field

[0001] The invention relates to the field of lithium batteries, and in particular to a lithium battery recycling device. Background Art

[0002] According to the different electrolyte materials used in lithium-ion batteries, lithium-ion batteries are divided into liquid lithium-ion batteries and polymer lithium-ion batteries or plastic lithium-ion batteries. The positive and negative electrode materials used in polymer lithium-ion batteries are the same as those of liquid lithium-ion batteries. The positive electrode materials are divided into lithium cobalt oxide, lithium manganese oxide, ternary materials and lithium iron phosphate materials, and the negative electrode is graphite. The working principle of the battery is basically the same. The main difference between them lies in the difference in electrolytes. Liquid lithium-ion batteries use liquid electrolytes, while polymer lithium-ion batteries use solid polymer electrolytes instead. This polymer can be "dry" or "colloidal". At present, most of them use polymer gel electrolytes.

[0003] At present, the wet recycling of lithium batteries includes processes such as cell loading, cell discharging, cell shell removal, fine disassembly and separation of positive and negative electrodes, electrode cutting, electrode soaking, powder stripping, powder filtering, cleaning and drying. At present, in the electrode soaking process, the cut electrode fragments are generally placed in a stripping solution (acid solution or alkaline solution), and the battery material and the current collector in the electrode fragments are separated by the chemical reaction between the electrode fragments and the stripping solution. However, this separation method has a long soaking time and low separation efficiency. If a stirring paddle is used to stir the stripping solution to accelerate the separation, the rotation of the stirring paddle is likely to cut the electrode fragments, causing the electrode fragments to further break, thereby resulting in battery material loss and a reduced battery material recovery rate. Summary of the invention

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0033] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] Secondly, the present invention is described in detail with reference to schematic diagrams. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0035] Furthermore, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0036] Example 1, reference Figure 1-Figure 7 This embodiment provides a lithium battery recycling device, including a recycling box 100, a separation component 200 and a precipitation component 300.

[0037] The recycling box 100 has a separation bin 101 and a sedimentation bin 102. The separation bin 101 is used to store and preliminarily process lithium batteries. For example, the crushed battery fragments will be preliminarily separated here, and the separation bin 101 is filled with acid or alkaline solution to dissolve the metal ions in the battery. The sedimentation bin 102 is used to store the liquid after the preliminary separation in order to further precipitate and extract valuable metal ions.

[0038] The separation assembly 200 includes a driving unit 201 and a waste box 202. The driving unit 201 is fixedly installed in the separation chamber 101. The waste box 202 reciprocates in the Y direction in the separation chamber 101 through the driving unit 201, which helps to accelerate the solid-liquid separation process.

[0039] The sedimentation assembly 300 includes a sedimentation box 301 and a circulation pipe 302. The sedimentation box 301 is fixedly installed in the sedimentation bin 102 and is equidistantly arranged along the circumferential direction of the sedimentation bin 102. It is used to store liquid that has been preliminarily separated so that the metal ions therein can be precipitated. The two ends of the circulation pipe 302 are respectively connected to the separation bin 101 and the sedimentation box 301 for transmitting liquid. A pump body for boosting is installed on the circulation pipe 302 to increase the pressure of the liquid flow and ensure that the liquid can be smoothly transported from the separation bin 101 to the sedimentation box 301.

[0040] A lithium battery recovery device of the present embodiment delivers the crushed lithium battery fragments into a waste box 202 in a separation chamber 101. The drive unit 201 drives the waste box 202 to reciprocate, thereby helping to stir the liquid, so that the solid and the liquid are fully in contact and solid-liquid separation is promoted. The separation efficiency can be effectively improved, the soaking time can be shortened, and the occurrence of electrode breakage can be reduced in the absence of rigid stirring, thereby avoiding battery material loss and improving the battery material recovery rate. The liquid that has been initially separated is transferred to a sedimentation box 301 through the circulation pipe 302 and the pump body. In the sedimentation box 301, metal ions gradually precipitate to form solid precipitates. The precipitated metal ions are further processed, such as filtering, drying, etc., and finally recovered to obtain high-purity metals. The entire process has a high degree of automation, which reduces the need for manual intervention.

[0041] Each structure is described in detail below with reference to the accompanying drawings.

[0042] Reference Figure 2 and Figure 4 The waste box 202 has a feed port 202a on the top, which is used to connect an external feed pipe 203 to introduce the crushed lithium battery fragments into the waste box 202. The side has a discharge port 202b and a box door 202c that can be rotatably opened and closed with the discharge port 202b, which is used to discharge the solid waste after preliminary treatment. The wall and bottom of the waste box 202 have through holes 202d for liquid to pass through while the solid remains in the box, thereby realizing solid-liquid separation.

[0043] Through the arrangement of the above structure, the crushed lithium battery fragments enter the waste box 202 through the feed pipe 203, and the driving unit 201 drives the waste box 202 to reciprocate in the separation chamber 101 to promote the solid-liquid separation in the mixture. Since the waste box 202 is provided with through holes 202d on the box wall and the bottom surface, the liquid can flow out from these through holes 202d, while the larger solid particles remain in the box. The separated liquid flows into the circulation pipe 302 through the discharge port 202b, and is then transported to the sedimentation box 301 through the pump body. When it is necessary to clean the solid waste in the waste box 202, the box door 202c can be opened for cleaning.

[0044] Reference Figure 2 and Figure 4The driving unit 201 includes a vertical pole 201a, a horizontal plate 201b, a first motor 201c and a turntable 201d. The vertical pole 201a is symmetrically installed in the separation bin 101, and the horizontal plate 201b is horizontally installed at the end of the vertical pole 201a away from the separation bin 101. The turntable 201d is rotatably installed on the horizontal plate 201b and close to the waste bin 202. The opposite surfaces of the turntable 201d and the waste bin 202 are both provided with connecting seats 201e, and a push rod 201f is connected between the relative connecting seats 201e. The first motor 201c is fixedly installed on the horizontal plate 201b and is transmission-connected to the extension shaft 201d-1 of the turntable 201d. Optionally, pulleys are fixedly installed on the output ends of the extension shaft 201d-1 and the first motor 201c, and are connected for transmission through belts. The waste bin 202 has a connecting portion 202e, and the connecting portion 202e is slidably installed on the vertical pole 201a.

[0045] It should be noted that the two connecting seats 201e are eccentrically arranged on the cross plate 201b and the turntable 201d, and both ends of the push rod 201f are rotatably installed in the connecting seat 201e to form a universal joint, which rotates regularly with the rotation of the turntable 201d.

[0046] Through the arrangement of the above structure, the first motor 201c is started, and the first motor 201c begins to rotate, and the turntable 201d is driven to rotate through the extension shaft 201d-1. When the turntable 201d rotates, the push rod 201f swings between the two connecting seats 201e. Since the two connecting seats 201e are eccentrically arranged on the cross plate 201b and the turntable 201d, under the connection action of the push rod 201f, the straight-line distance between the two connecting seats 201e increases or decreases intermittently, causing the waste box 202 to reciprocate in the Y direction along the vertical pole 201a, which helps to stir the mixture in the waste box 202 and promote solid-liquid separation.

[0047] Reference Figure 7 Furthermore, a sleeve 202e-1 is fixedly installed on the top surface of the connecting portion 202e, a sliding pin 202e-2 is fixedly installed in the sleeve 202e-1, a vertical shaft 202f is rotatably installed in the separation chamber 101, one end of the vertical shaft 202f passes through the first airbag 400 to the waste box 202, and a wave groove 202f-2 matched with the sliding pin 202e-2 is opened on the vertical shaft 202f. When the connecting portion 202e makes reciprocating motion on the vertical rod 201a, the vertical shaft 202f is forced to rotate, and a spoiler belt 202f-1 is fixedly installed on the outer edge surface of the vertical shaft 202f to increase the turbulence of the liquid flow and improve the stirring effect.

[0048] Reference Figure 3A first airbag 400 is fixedly installed in the separation chamber 101. The first airbag 400 is located between the bottom surface of the separation chamber 101 and the waste box 202, and is in contact with the waste box 202. A side of the first airbag 400 close to the waste box 202 has an air pipe 401, and the air pipe 401 passes through the through hole 202d and is located in the waste box 202.

[0049] The first airbag 400 has an air inlet pipe 402 , and one-way valves are fixedly installed in the air inlet pipe 402 and the air pipe 401 . The working surfaces of the two one-way valves are opposite to each other, ensuring that the airflow can only flow in one direction.

[0050] Furthermore, a spiral air duct 101a is provided in the wall of the separation bin 101, one end of the spiral air duct 101a is connected to the outside, and a filter capable of filtering dust particles in the air is installed on the connected interface, the other end of the spiral air duct 101a is connected to the air inlet pipe 402, and a heating element, preferably a resistance wire, is fixedly installed on the inner wall of the spiral air duct 101a.

[0051] It should be noted that a spring is added inside the first airbag 400 , and the first airbag 400 can be rapidly expanded and reset through the elastic reset of the spring.

[0052] Through the arrangement of the above-mentioned structure, as the waste box 202 is squeezed back and forth, the air in the first airbag 400 can only be discharged from the one-way valve in the air pipe 401 and injected into the waste box 202 due to the obstruction of the one-way valve in the air inlet pipe 402, which helps to improve the stirring effect in the mixture, accelerate the solid-liquid separation process, and better disperse the solid particles in the liquid, thereby improving the separation efficiency. When the first airbag 400 rebounds, the internal negative pressure allows outside air to enter through one end of the spiral airway 101a. The air is heated by the heating element when passing through the spiral airway 101a. The heated air enters the first airbag 400 through the air inlet pipe 402, which helps to increase the temperature of the mixture, thereby improving the solid-liquid separation effect.

[0053] Furthermore, when there is no flowing liquid in the separation chamber 101, the reciprocating motion of the waste box 202 and the turbulence of the hot air accelerate the drying effect of the internal materials.

[0054] Reference Figure 2 and Figure 5The sedimentation box 301 includes a box body 301a with an opening at one end and a pressure plate 301b slidably installed in the box body 301a, which is used to compact the precipitated solids. A baffle 301c is rotatably installed at the open end of the box body 301a. The baffle 301c has a liquid outlet 301c-1 for externally connecting to a liquid outlet pipe 301d for controlling the outflow of liquid. A filter membrane 301c-2 is installed in the liquid outlet 301c-1 for filtering solid particles in the liquid. A second motor 301e is fixedly installed on the outer wall of the box body 301a, and the output end of the second motor 301e is transmission-connected to the baffle 301c.

[0055] Through the arrangement of the above structure, the liquid that has undergone preliminary separation is transferred to the sedimentation tank 301 through the circulation pipe 302 and the pump body. In the sedimentation tank 301, the metal ions gradually settle down to form solid sediment. The sediment is compacted by the pressing plate 301b to reduce the volume for subsequent processing. The clarified liquid is discharged through the liquid outlet pipe 301d for harmless treatment. The output end of the second motor 301e drives the baffle 301c to rotate, and the compacted sediment falls off into the sedimentation bin 102 through the opening of the box body 301a.

[0056] Furthermore, referring to Figure 2 and Figure 6 The end of the vertical shaft 202f away from the rotating disk 201d extends into the sedimentation bin 102 and abuts against the disk 500 for rotational engagement. The engagement method is as follows: Figure 6 As shown, a sleeve of the vertical shaft 202f is provided with a ball, which can rotate in all directions.

[0057] A triangular plate 501 is fixedly mounted on one side of the abutment plate 500 close to the box body 301a. The triangular plate 501 has a first inclined surface 501a. An abutment rod 301f is fixedly mounted on the pressure plate 301b. The abutment rod 301f has a second inclined surface 301f-1 abutting against the first inclined surface 501a.

[0058] Preferably, the abutting rod 301f is a spring telescopic rod, and when the first inclined surface 501a squeezes the second inclined surface 301f-1, the abutting rod 301f contracts to avoid hard contact.

[0059] As an option, a sealing gasket is fixedly installed on the surface of the baffle 301c.

[0060] Through the arrangement of the above structure, the separated liquid enters the box body 301a through the circulation tube 302 and then pushes up the pressure plate 301b, and the abutment rod 301f moves up accordingly and abuts against the triangular plate 501. When the first inclined surface 501a of the triangular plate 501 abuts against the second inclined surface 301f-1 of the abutment rod 301f, the pressure plate 301b is prompted to move in the box body 301a to compact the sediment, thereby reducing the need for manual intervention and time and improving the recovery efficiency. The sealing gasket is fixedly installed on the surface of the baffle 301c to improve the sealing performance between the baffle 301c and the open end of the box body 301a to ensure that the liquid will not leak when the baffle 301c is opened or closed.

[0061] Reference Figure 5 An air hole 301a-1 and a second air bag 301h are provided on the top surface of the box body 301a. The second air bag 301h is connected to the box body 301a and a one-way valve is installed at the connection point. A reflux pipe 301g is fixedly connected between the second air bag 301h and the liquid outlet pipe 301d. A one-way valve is also fixedly installed in the reflux pipe 301g and the air hole 301a-1.

[0062] Through the arrangement of the above structure, when the pressure plate 301b rises in the box body 301a, the gas originally existing in the box body 301a enters the second airbag 301h for storage, and when the first inclined surface 501a of the triangular plate 501 abuts against the second inclined surface 301f-1 of the abutment rod 301f, the abutment rod 301f will be squeezed to move downward, and the downward-moving pressure rod 301f-2 squeezes the second airbag 301h. Under the action of the one-way valve, the air in the second airbag 301h enters the reflux pipe 301g and enters the circulation pipe 302, so as to backwash the circulation pipe 302 and reduce the blockage of sediment.

[0063] In summary, the working principle of a lithium battery recycling device is as follows:

[0064] First, the crushed lithium battery fragments and the stripping solution are sent to the waste box 202 in the separation chamber 101;

[0065] Next, the first motor 201c is started, and the first motor 201c begins to rotate, and drives the turntable 201d to rotate through the extension shaft 201d-1. When the turntable 201d rotates, the push rod 201f moves between the two connecting seats 201e. Since the two connecting seats 201e are eccentrically arranged on the cross plate 201b and the turntable 201d, under the connection action of the push rod 201f, the straight-line distance between the two connecting seats 201e increases or decreases intermittently, causing the waste box 202 to reciprocate along the vertical rod 201a in the Y direction;

[0066] Then, with the reciprocating squeezing of the waste box 202, the air in the first airbag 400 can only be discharged from the one-way valve in the air pipe 401 and injected into the waste box 202 due to the obstruction of the one-way valve in the air inlet pipe 402, which helps to improve the stirring effect in the mixture, accelerate the solid-liquid separation process, and better disperse the solid particles in the liquid, thereby improving the separation efficiency. When the first airbag 400 rebounds, the internal negative pressure causes the outside air to enter through one end of the spiral airway 101a. The air is heated by the heating element when passing through the spiral airway 101a. The heated air enters the first airbag 400 through the air inlet pipe 402, which helps to increase the temperature of the mixture, thereby improving the solid-liquid separation effect.

[0067] Then, the first motor 201c stops rotating, and the separated liquid enters the box body 301a through the circulation pipe 302 and pushes up the pressure plate 301b, and the abutment rod 301f moves upward and abuts against the triangular plate 501;

[0068] Then, a new round of broken lithium battery fragments and stripping liquid are sent to the waste box 202 in the separation chamber 101, and the first motor 201c is started. During the mixing and separation process of the mixture, the abutment rod 301f moves up and abuts against the triangular plate 501. When the first inclined surface 501a of the triangular plate 501 abuts against the second inclined surface 301f-1 of the abutment rod 301f, the pressing plate 301b is prompted to move in the box body 301a to compact the sediment, thereby reducing the need for manual intervention and time and improving the recovery efficiency. The sealing gasket is fixedly installed on the surface of the baffle 301c to improve the sealing performance between the baffle 301c and the opening end of the box body 301a, and ensure that the liquid will not leak when the baffle 301c is opened or closed;

[0069] Finally, when the pressure plate 301b rises in the box body 301a, the gas originally in the box body 301a enters the second airbag 301h for storage, and when the first inclined surface 501a of the triangular plate 501 abuts against the second inclined surface 301f-1 of the abutting rod 301f, the downward-moving pressure rod 301f-2 squeezes the second airbag 301h, and the air in the second airbag 301h enters the reflux pipe 301g and enters the circulation pipe 302 under the action of the one-way valve, backwashing the circulation pipe 302 to reduce the blockage of sediment.

[0070] Importantly, it should be noted that the construction and arrangement of the present application shown in a plurality of different exemplary embodiments are only exemplary.
