The soaking section includes an outer cylinder and an inner cylinder. The bottom of the inner cylinder is provided with a sealing plate, and several clamping openings are provided on the outer side of the inner cylinder. The outer cylinder is fitted over the inner cylinder, forming a gap with the inner cylinder.

Description

Technical Field

[0001] This invention relates to the field of power battery recycling technology, and in particular to a battery degumming and residual gum separation device. Background Technology

[0002] During the recycling of power batteries, residual adhesive needs to be removed. When the power battery pack is soaked in adhesive remover, the residual adhesive will gradually soften and eventually fall off.

[0003] For example, Chinese patent CN 216728533 U describes a constant temperature water bath for removing adhesive from the surface of battery cells. It includes: a housing with a loading area and a heating area, the loading area being located above the heating area; a loading plate installed inside the housing, positioned between the loading area and the heating area, the loading plate having micro-holes; an anti-tilting device including several partitions connected to the housing, the distance between the partitions being adjustable, and the partitions located within the loading area; and a heating device installed inside the housing. This constant temperature water bath enables batch removal of residual adhesive from the surface of battery cells, improving work efficiency.

[0004] The aforementioned soaking degumming technology is a commonly used method for degumming power batteries at present. However, the residual adhesive removed by soaking will accumulate at the bottom of the tank, resulting in the problem of residual adhesive accumulation. This makes it impossible to clean the degumming agent in a timely manner, thus requiring an additional station to separate the degumming agent from the residual adhesive. In the degumming process of battery cell recycling, this affects the efficiency of the production line. Summary of the Invention

[0005] In view of this, it is necessary to provide a battery adhesive removal and residual adhesive separation device to solve the technical problem in the prior art where residual adhesive accumulates during the soaking process of the adhesive remover on the power battery pack, resulting in the adhesive remover not being able to clean it in a timely manner.

[0006] To achieve the above-mentioned technical objectives, the present invention provides a battery adhesive removal and residual adhesive separation device, comprising:

[0007] The soaking section includes an outer cylinder and an inner cylinder. The bottom of the inner cylinder is provided with a sealing plate, and several mounting holes are opened on the outer side of the inner cylinder. The outer cylinder is fitted over the inner cylinder and forms a gap with the inner cylinder. The mounting holes are used for sealing the mounting of the battery cell, and the end of the battery cell with residual adhesive is inserted into the gap. The gap is used to accumulate adhesive remover and soak and remove the residual adhesive on the battery cell.

[0008] The glue discharge section includes a bottom-controlled discharge container, which is located at the bottom of the outer cylinder and communicates with the interlayer gap. The glue discharge section is used for residual glue from the soaking section to sink downwards and separate from the glue remover.

[0009] Furthermore, it also includes a rotating component, which is placed on top of the outer cylinder and connected to the inner cylinder, for driving the inner cylinder to rotate inside the outer cylinder.

[0010] Furthermore, it also includes a heating component, which is built into the interlayer cavity for heating the stored adhesive remover.

[0011] Furthermore, the heating assembly includes a heating pipe, a heat medium inlet pipe, and a heat medium outlet pipe. The heating pipe is disposed within the interlayer gap, and both the heat medium inlet pipe and the heat medium outlet pipe are disposed on the heating pipe.

[0012] Furthermore, the heating pipe includes a lower ring pipe, a vertical pipe, and an upper ring pipe. Several vertical pipes are arranged between the upper ring pipe and the lower ring pipe, and the vertical pipes are connected to both the upper ring pipe and the lower ring pipe. The heat medium inlet pipe is arranged on the lower ring pipe, and the heat medium outlet pipe is arranged on the upper ring pipe.

[0013] Furthermore, the cross-section of the vertical tube is trapezoidal, and the bottom surface of the trapezoid is arc-shaped and fits against the inner wall of the outer cylinder.

[0014] Furthermore, an inlet pipe and an overflow pipe are provided opposite to each other on the outer side of the outer cylinder.

[0015] Furthermore, the rotating component includes a support member, a drive motor, a transmission shaft, and a rotating frame. The drive motor is fixed on the support member, the transmission shaft is fixed on the output shaft of the drive motor, and the rotating frame is fixed at the other end of the transmission shaft. The support member is supported on the outer cylinder, and the rotating frame is connected to the inner cylinder.

[0016] Furthermore, the support includes a cover plate that covers the top of the outer cylinder.

[0017] Furthermore, the container is conical in shape, and a discharge valve is provided at the bottom of the container.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: the adhesive remover is contained in the interlayer space formed by the outer cylinder and the inner cylinder, which is different from the soaking method of the traditional structure. The residual adhesive is separated from the soaking part, which facilitates the separation of residual adhesive and adhesive remover by density difference, and the residual adhesive can be discharged downward to avoid residual adhesive accumulation; the adhesive remover is heated by the heating component, which can improve the adhesive removal performance of the adhesive remover; the inner cylinder is rotated by the rotating component, and the residual adhesive is subjected to centrifugal force and the impact force of adhesive remover during the rotation of the battery cell, which improves the adhesive removal efficiency.

[0029] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0030] like Figure 1-3 As shown, the present invention provides a battery adhesive removal and residual adhesive separation device, including an immersion section and an adhesive discharge section. The immersion section is used to immerse the battery cell to soften and remove residual adhesive. The adhesive discharge section is adjacent to the immersion section and removes and separates the residual adhesive from the immersion section, thereby avoiding the stacking of residual adhesive in the immersion section. Furthermore, by utilizing the difference in density between the adhesive remover and the residual adhesive, the layers are separated, with the residual adhesive discharged from the adhesive discharge section and the adhesive remover discharged from the immersion section.

[0031] Specifically, the soaking section includes an outer cylinder 1 and an inner cylinder 3. A sealing plate is provided at the bottom of the inner cylinder 3, which isolates the inner cylinder 3 from the outer cylinder 1 from the bottom. Several mounting openings 301 are provided on the outer side of the inner cylinder 3. The mounting openings 301 are used for sealing the battery cells. A sealing ring is provided on the inner side of the mounting opening 301, which is used to seal tightly against the outer surface of the battery cell during mounting, preventing the adhesive remover from seeping into the inner cylinder 3 from the mounting opening 301. The outer cylinder 1 is fitted over the inner cylinder 3, forming a sandwich space 4 with the inner cylinder 3. The end of the battery cell with residual adhesive is inserted into the sandwich space 4. The sandwich space 4 is used to accumulate adhesive remover and soak and remove the residual adhesive on the battery cell. The adhesive remover is injected after the battery cell is inserted into the insertion port 301. The adhesive is injected into the sandwich space 4 and, due to the sealing plate at the bottom of the inner cylinder 3, it does not flow into the interior of the inner cylinder 3. The end of the battery cell with residual adhesive passes through the insertion port 301 and is placed in the sandwich space 4, where it is soaked in the adhesive remover to achieve the purpose of soaking and removing adhesive.

[0032] The adhesive discharge section includes a receiving box 2, which is located at the bottom of the outer cylinder 1. The top of the receiving box 2 is identical in shape and size to the bottom of the outer cylinder 1, forming a perfectly matched connection. The interlayer gap 4 is also connected to the receiving box 2, so that when the adhesive remover is poured in, it also flows into the receiving box 2 through the interlayer gap 4. When the density of the residual adhesive and the adhesive remover is different, the residual adhesive will sink into the receiving box 2 and concentrate there, thus removing the residual adhesive from the soaking section. The adhesive remover, which is mostly in the soaking section, can be discharged from the top of the soaking section.

[0033] Understandably, in order to improve the stability of the card mounting, a clamp can be set on the card mounting port 301 to improve the stability of the card mounting.

[0034] In addition, the battery adhesive removal and residual adhesive separation device also includes a rotating component 6, which is placed on the top of the outer cylinder 1 and connected to the inner cylinder 3. It is used to drive the inner cylinder 3 to rotate inside the outer cylinder 1. Through the rotation of the inner cylinder 3, the battery cell installed in the mounting port 301 is driven to rotate synchronously, so as to achieve the effect of centrifugal force assisting the residual adhesive to detach from the battery cell. Furthermore, the battery cell will be impacted by the adhesive removal agent during the rotation process, making the residual adhesive detach more efficiently.

[0035] Understandably, the rotation direction can be alternating between clockwise and counterclockwise to achieve a better degumming effect.

[0036] In one embodiment, in order to improve the effect of removing residual adhesive, the battery adhesive removal and residual adhesive separation device further includes a heating component 5, which is used to regulate the temperature of the adhesive remover. The adhesive removal effect of the adhesive remover is improved by heating the adhesive. The heating component 5 is built into the interlayer cavity 4 and is used to heat the stored adhesive remover, thereby achieving the purpose of heating the adhesive remover in the interlayer cavity 4 and improving the adhesive removal efficiency.

[0037] Specifically, the heating assembly 5 includes a heating pipe 51, a heat medium inlet pipe 52, and a heat medium outlet pipe 53. The heating pipe 51 is disposed within the interlayer cavity 4 to heat the adhesive remover stored in the interlayer cavity 4. The heat medium inlet pipe 52 and the heat medium outlet pipe 53 are both disposed on the heating pipe 51, and the heating medium flows through the heating pipe 51 for heating.

[0038] Understandably, existing heating devices output a heating medium, which can be a fluid heat transfer medium that carries heat, such as air, oil, or steam.

[0039] Furthermore, the heating pipe 51 includes a lower ring pipe 511, a vertical pipe 512, and an upper ring pipe 513. Several vertical pipes 512 are arranged between the upper ring pipe 513 and the lower ring pipe 511, and the vertical pipes 512 are connected to both the upper ring pipe 513 and the lower ring pipe 511. The upper ring pipe 513 and the lower ring pipe 511 are used to connect all the vertical pipes 512, so that the heating medium flows in the vertical pipes 512 and heat is conducted by the vertical pipes 512 to heat the adhesive remover.

[0040] Furthermore, the heat medium inlet pipe 52 is installed on the lower ring pipe 511, and the heat medium outlet pipe 53 is installed on the upper ring pipe 513. The heating medium flows from bottom to top, which is more conducive to filling all the vertical pipes 512.

[0041] Furthermore, in order to reduce the interference of the vertical tube 512 with the residual adhesive, the cross-section of the vertical tube 512 is trapezoidal, and the bottom surface of the trapezoid is arc-shaped and fits against the inner wall of the outer cylinder 1, thereby avoiding the formation of a gap between the vertical tube 512 and the outer cylinder 1, making it less likely for residual adhesive to be trapped on the surface, which is conducive to the sinking of the residual adhesive.

[0042] In one embodiment, in order to facilitate the separation of the adhesive remover, an inlet pipe 101 and an overflow pipe 102 are provided opposite to each other on the outer side of the outer cylinder 1 at the same horizontal height. The inlet pipe 101 is used to introduce the adhesive remover, and the overflow pipe 102 is used to automatically overflow the adhesive remover.

[0043] It is understandable that the position of the overflow pipe 102 can be lower than the position of the inlet pipe 101, while the position of the overflow pipe 102 only needs to be higher than the highest clamping port 301.

[0044] In one embodiment, to achieve the purpose of rotating the inner cylinder 3, the rotating component 6 includes a support 61, a drive motor 62, a transmission shaft 63, and a rotating frame 64. The drive motor 62 is fixed on the support 61, the transmission shaft 63 is fixed on the output shaft of the drive motor 62, and the rotating frame 64 is fixed on the other end of the transmission shaft 63. The support 61 is supported on the outer cylinder 1, and the rotating frame 64 is connected to the inner cylinder 3. It is driven by the drive motor 62 to drive the transmission shaft 63 and the rotating frame 64 to rotate. The rotating frame 64 is fixedly connected to the inner cylinder 3, thereby driving the inner cylinder 3 to rotate.

[0045] Furthermore, for ease of support, the support member 61 includes a cover plate that covers the top of the outer cylinder 1.

[0046] In one embodiment, in order to facilitate the discharge of residual adhesive, the container 2 is cone-shaped, and a discharge valve 201 is provided at the bottom of the container 2. By opening the discharge valve 201, the interior of the container 2 can be connected, and the residual adhesive inside can be discharged downward.

[0047] The specific workflow of this invention is as follows: In use, first lift the rotating component 6, simultaneously removing the inner cylinder 3. Then, insert and secure the battery cells into the mounting holes 301 on the inner cylinder 3, filling all mounting holes 301. Next, place the inner cylinder 3 back into the outer cylinder 1, and cover the top of the outer cylinder 1 with the support component 61. Then, inject the adhesive remover into the interlayer gap 4 through the liquid inlet pipe 101, and input the heating medium into the heating pipe 51 through the heat medium outlet pipe 53 to heat the adhesive remover to the required temperature. During soaking, start the drive motor 62. Under the transmission of the drive shaft 63 and the rotating frame 64, the inner cylinder 3 rotates, causing the battery cells on it to rotate. During the rotation of the battery cells, the residual adhesive is subjected to centrifugal force and the impact force of the adhesive remover, causing the residual adhesive to fall off from the bottom of the battery cells, thereby effectively improving the adhesive removal efficiency. During the degumming process, due to the different densities of the degumming agent and the residual adhesive, the two are separated during equipment operation. The residual adhesive sinks into the lower receiving tank 2 and is discharged from the bottom discharge valve 201, while the degumming agent overflows and is discharged from the overflow pipe 102.

[0048] The entire workflow is now complete, and anything not described in detail in this specification is existing technology known to those skilled in the art.

[0049] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
