Description

Technical Field

[0001] This utility model relates to the field of battery recycling technology, specifically to a residual adhesive collection device for removing adhesive from battery cells. Background Technology

[0002] To facilitate the recycling of power batteries, it is necessary to remove the adhesive and detach the residual adhesive from the batteries.

[0003] For example, Chinese invention patent CN116422636A, entitled "A Battery Adhesive Removal and Residual Adhesive Separation Device," includes an soaking section and an adhesive discharge section. The soaking section comprises an outer cylinder and an inner cylinder. A sealing plate is provided at the bottom of the inner cylinder, and several locking ports are opened on the outer side of the inner cylinder. The outer cylinder is fitted over the inner cylinder, forming a gap with it. The locking ports are used for sealing and locking battery cells, with the end of the locked battery cell containing residual adhesive inserted into the gap. The gap is used to accumulate adhesive remover and soak and remove residual adhesive from the battery cell. This device uses the gap formed by the outer and inner cylinders to contain the adhesive remover, separating the residual adhesive from the soaking section. This facilitates the separation of residual adhesive and adhesive remover based on their density difference, and allows the residual adhesive to be discharged downwards, preventing accumulation. However, during use, some residual adhesive will float on the surface of the adhesive remover, requiring manual retrieval and collection by workers.

[0004] Therefore, there is an urgent need for a residual adhesive collection device for battery cell degumming, to solve the problem in the existing technology where the separated residual adhesive floats on the surface of the degumming agent, requiring manual retrieval and collection by workers, which is inconvenient to use.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0007] This utility model provides a residual adhesive collection device for removing adhesive from battery cells, comprising:

[0008] Reactor;

[0009] A material cylinder, built into the reactor, is hollow inside and open at the top. The circumferential sidewalls of the material cylinder also have multiple through holes communicating with the interior of the reactor; and

[0010] A filter assembly includes a filter screen disposed below the liquid level in a material cylinder.

The filter screen has a folded state and an unfolded state, and the filter screen can open and close the material channel in the folded state and unfolded state, respectively.

[0011] In some embodiments, the opening end of the material cylinder is stepped and has a mounting groove. The filter assembly further includes a bracket, which is annular and connected to the filter. The bracket is slidably inserted into the mounting groove and detachably connected to the inner wall of the mounting groove.

[0012] In some embodiments, the bottom inner wall of the mounting groove is provided with at least two slots, and the filter assembly further includes at least two snap-fit ​​members, which are all connected to the bracket and snap-fit ​​with at least two slots respectively.

[0013] In some embodiments, the snap-fit ​​member has a connecting end and an elastic snap-fit ​​portion.

The cross-sectional area of ​​the elastic snap-fit ​​portion of the snap-fit ​​member is larger than the cross-sectional area of ​​the slot, so that the elastic snap-fit ​​portion of the snap-fit ​​member is locked into the slot.

[0014] In some embodiments, the sidewall of the mounting groove is further provided with at least two guide grooves, and the filter assembly further includes at least two guide blocks, one end of which is connected to the bracket and the other end is slidably embedded in the guide groove.

[0015] In some embodiments, the filter screen is fan-shaped, disposed relative to the inner hole of the bracket, and together with the inner hole of the bracket, forms the material channel.

[0017] In some embodiments, the bracket has a connecting groove on the side opposite to the slot. The connecting groove is annular and communicates with the annular sliding groove. The filter assembly also includes two sliding rods and a limiting part. The sliding rods are arranged in a one-to-one correspondence with the sliding balls.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] To address the technical problem of inconvenience caused by the need for manual retrieval and collection of residual adhesive floating on the surface of the adhesive remover, this invention provides a residual adhesive collection device for battery cell adhesive removal. This device utilizes a foldable filter screen 31 installed at the opening of the material cylinder 2. Folding or unfolding the filter screen 31 relative to the material cylinder 2 adjusts the opening or closing of the material channel 32. The material channel 32 is opened during feeding or discharging to facilitate material loading and unloading. When residual adhesive needs to be cleaned, the material channel 32 is closed, and the filter screen 31 is removed from the material cylinder 2 to collect and separate the residual adhesive floating on the liquid surface.

[0030] It should be noted that the residual adhesive collection device for cell degumming described in this utility model is used in, but not limited to, the field of battery recycling technology. For ease of explanation, this utility model only uses the application of the residual adhesive collection device for cell degumming in the field of battery recycling technology as an example for explanation. The principle of the residual adhesive collection device for cell degumming in other types of equipment is essentially the same as that in the field of battery recycling technology, and will not be described in detail here.

[0031] Please see Figure 1 , Figure 1This is a schematic diagram of the structure of a residual adhesive collection device for removing adhesive from battery cells according to an embodiment of the present invention. The residual adhesive collection device for removing adhesive from battery cells includes: a reaction vessel 1, a material cylinder 2, and a filter assembly 3. The material cylinder 2 is built into the reaction vessel 1. The material cylinder 2 is hollow inside and open at the top. The circumferential sidewall of the material cylinder 2 is also provided with multiple through holes to connect the inside of the material cylinder 2 with the inside of the reaction vessel 1. The filter assembly 3 includes a filter screen 31. The filter screen 31 is located below the liquid level in the material cylinder 2 and is detachably connected to the open end of the material cylinder 2. The filter screen 31 and the opening of the material cylinder 2 together form a material channel 32 that allows material to pass through. The filter screen 31 has a folded state and an unfolded state. The filter screen 31 can open and close the material channel 32 when it is in the folded state and unfolded state, respectively.

[0032] Compared to existing technologies, this device features a foldable filter screen 31 installed at the open end of the material cylinder 2. The folding or unfolding of the filter screen 31 relative to the material cylinder 2 adjusts the opening or closing of the material channel 32. The material channel 32 is opened during feeding or discharging to facilitate material loading and unloading. When it is necessary to clean residual adhesive, the material channel 32 is closed, and the filter screen 31 is removed from the material cylinder 2 to collect and separate the residual adhesive floating on the liquid surface. This solves the technical problem in existing technologies where the separated residual adhesive floats on the surface of the adhesive remover, requiring manual retrieval and collection by workers, which is inconvenient to use.

[0033] Furthermore, the filter screen 31 is made of a flexible material that can be unfolded or folded to adjust its size. When the filter screen 31 is unfolded, the size of the material channel 32 formed between the filter screen 31 and the material cylinder 2 decreases, which facilitates the collection and separation of residual adhesive floating on the liquid surface. When the filter screen 31 is folded, the size of the material channel 32 formed between the filter screen 31 and the material cylinder 2 increases, which facilitates the feeding and unloading of the material cells.

[0034] In this embodiment, as shown in Figures 2 to 3, ... Figure 4 The filter assembly 3 also includes a bracket 33, at least two snap-fit ​​pieces 34, at least two guide blocks 35, two sliding balls 36, two sliding rods 37, and a limiting part 38.

[0035] The material cylinder 2 has a stepped opening and an installation groove. The bracket 33 is annular and connected to the filter screen 31. The bracket 33 is slidably inserted into the installation groove and is detachably connected to the inner wall of the installation groove.

[0036] The bracket 33 serves to connect the filter screen 31 and the opening of the material cylinder 2. At the same time, the bracket 33 can support the filter screen 31 to be folded or unfolded, thereby blocking or opening the opening of the material cylinder 2.

[0037] In one embodiment, as shown in the figure, at least two slots are provided on the bottom inner wall of the mounting groove, and at least two snap-fit ​​pieces 34 are connected to the bracket 33 and snap-fit ​​into the at least two slots respectively.

[0038] The bracket 33 achieves a detachable connection between the filter screen 31 and the material cylinder 2 through the snap-fit ​​between at least two snap-fit ​​pieces 34 and the slot.

[0039] In one embodiment, please refer to Figure 2 The snap-fit ​​component 34 has a connecting end and an elastic snap-fit ​​part. The connecting end of the snap-fit ​​component 34 is connected to the bracket 33, and the elastic snap-fit ​​part can be inserted into the slot. The cross-sectional area of ​​the elastic snap-fit ​​part of the snap-fit ​​component 34 is larger than the cross-sectional area of ​​the slot, so that the elastic snap-fit ​​part of the snap-fit ​​component 34 is locked into the slot.

[0040] The elastic snap-fit ​​part of the snap-fit ​​member 34 is snapped into the slot by elastic snap-fit. When the elastic snap-fit ​​part of the snap-fit ​​member 34 is inserted into the slot, the area of ​​the elastic snap-fit ​​part of the snap-fit ​​member 34 is larger than the cross-sectional area of ​​the slot, so that the elastic snap-fit ​​part of the snap-fit ​​member 34 is snapped into the slot. When force is applied to the snap-fit ​​member 34, the elastic snap-fit ​​part of the snap-fit ​​member 34 can be separated from the slot, thereby realizing the detachable connection between the bracket 33 and the material cylinder 2.

[0041] Furthermore, the snap-fit ​​element 34 here is a common and readily available elastic element on the market. This is a conventional setting known to those skilled in the art, and will not be described in detail here.

[0042] In one embodiment, please refer to Figure 2 The side wall of the mounting groove is also provided with at least two guide grooves. One end of the guide block 35 is connected to the bracket 33, and the other end is slidably embedded in the guide groove.

[0043] The sliding fit between the guide block 35 and the guide groove guides the sliding connection between the support 33 and the material cylinder 2.

[0044] In one embodiment, please refer to Figure 3 , Figure 4 The filter screen 31 is fan-shaped and is positioned relative to the inner hole of the support 33. The filter screen 31 and the inner hole of the support 33 together form a material channel 32. The filter screen 31 is folded or unfolded relative to the inner hole of the support 33 to open or close the material channel 32.

[0045] After the fan-shaped filter screen 31 is unfolded relative to the support 33, it can form a complete circle and block the inner hole of the support 33, thus playing the role of filtering and separating residual adhesive.

[0046] In one embodiment, please refer to Figures 2 to 4The bracket 33 is also provided with an annular groove, which is connected to the inner hole of the bracket 33. Two sliding balls 36 are respectively slidably embedded in the annular groove and respectively connected to the two ends of the filter screen 31. The two sliding balls 36 slide closer or further away from each other along the guide of the annular groove, which can drive the filter screen 31 to fold or unfold relative to the inner hole of the bracket 33.

[0047] By connecting two sliding balls 36 to both ends of the filter screen 31, the filter can be unfolded or folded, making it convenient for users. The annular groove and the sliding balls 36 work together to guide the filter screen 31 to unfold or fold in a circular shape, forming an unfolded state and a folded state, and can completely block the material channel 32, improving the efficiency of residual glue separation.

[0048] In one embodiment, please refer to Figure 2 The bracket 33 also has a connecting groove on the side away from the slot. The connecting groove is annular and communicates with the annular sliding groove. The sliding rod 37 and the sliding ball 36 are arranged in a one-to-one correspondence. One end of the sliding ball 36 is built into the connecting groove and connected to the sliding ball 36. The other end extends in a direction away from the bracket 33. The limiting part 38 is connected to the other end of one sliding rod 37 and can be engaged with the other end of another sliding rod 37 to limit the two sliding rods 37 from sliding away from each other.

[0049] The sliding rod 37 is slidably connected in the communicating groove, and one end of the sliding rod 37 extends away from the bracket 33, which makes it convenient for the user to unfold or fold the filter screen 31. The limiting part 38 is used to connect the two sliding rods 37 to form a whole, so as to avoid accidental folding when the filter screen 31 separates residual glue.

[0050] In one embodiment, please refer to Figure 5 The limiting part 38 is semi-circular, and its two ends are rotatably connected to a sliding rod 37, and can be rotated relative to the sliding rod 37 and then sleeved on the other sliding rod 37.

[0051] The rotating limiting part 38 can be fitted onto another sliding rod 37, so that the two sliding rods 37 form a whole, which is not only simple in structure but also convenient to operate.

[0052] Furthermore, the reverse rotation of the limiting part 38 separates the limiting part 38 from the other sliding rod 37, and can push the filter screen 31 to fold.

[0053] In this embodiment, as Figure 3 , Figure 4 As shown, the device also includes a carrying ring 4, with both ends of the carrying ring 4 rotatably connected to the bracket 33, and the minimum diameter of the carrying ring 4 is greater than the diameter of the bracket 33.

[0054] By setting the minimum diameter to be greater than the diameter of the support 33, the carrying ring 4 can be hidden and stored on one side of the support 33. When needed, the carrying ring 4 can be driven to rotate relative to the support 33 and set up vertically, so that the user can easily separate the support 33 from the material cylinder 2, thereby collecting and separating the residual glue floating on the liquid surface.

[0055] Furthermore, the handle 4 is located on one side of the bracket 33 to avoid affecting the loading and unloading of materials.

[0056] To better understand this utility model, the following is combined with... Figures 1 to 5 The technical solution of this utility model is described in detail below:

[0057] The reactor 1 contains a material cylinder 2 for holding battery cells. The interior of the material cylinder 2 is connected to the interior of the reactor 1 through multiple through holes. A filter screen 31 is located at the open end of the material cylinder 2 and is detachably connected to it. The filter screen 31 is positioned below the liquid level inside the material cylinder 2, forming an adjustable material channel 32 between itself and the opening of the material cylinder 2. The filter screen 31 has a folded state and an unfolded state, which respectively open and close the material channel 32. Compared to the prior art, by setting a foldable filter screen 31 at the open end of the material cylinder 2, the folding or unfolding of the filter screen 31 relative to the material cylinder 2 can adjust the opening or closing of the material channel 32. The material channel 32 is opened during feeding or discharging to facilitate material loading and unloading. The material channel 32 is closed when it is necessary to clean residual adhesive. Removing the filter screen 31 from the material cylinder 2 allows for the collection and separation of residual adhesive floating on the liquid surface.

[0058] In the specific working process of this utility model, firstly, the bracket 33 is inserted into the open end of the material cylinder 2 along the guide groove, and the elastic locking part of the locking member 34 is locked in the locking groove. Then, the filter screen 31 is folded, and material is added into the material cylinder 2 through the material channel 32. The degumming agent is added into the material cylinder 2, and the liquid level of the degumming agent is higher than the plane where the filter screen 31 is located. After the degumming is completed, the filter screen 31 is unfolded along the guide of the annular slide groove. The unfolded filter screen 31 blocks the material channel 32. Finally, the bracket 33 and the filter screen 31 are taken out along the open end of the material cylinder 2. The unfolded filter screen 31 can concentrate and separate the residual glue floating on the liquid surface.

[0059] This device, through the aforementioned structure, solves the technical problem in the prior art where the separated residual adhesive floats on the surface of the adhesive remover, requiring manual retrieval and collection by workers, thus causing inconvenience in use.

[0060] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
