Description

TECHNICAL FIELD

[0001] The application relates to the field of oil filtering devices, in particular to an alkaline solution oil filtering device for power battery aluminum shells. BACKGROUND

[0002] The power battery is a power supply for providing a power source for tools, and is mainly used for providing power for electric vehicles, electric trains, electric bicycles and the like. In the production process of the power battery, the alkaline solution is usually used to clean the surface of the battery.

[0003] In the related art, in order to improve the utilization rate of resources, a filtering device is usually used to separate oil and water from the used alkaline solution, so as to reuse the separated oil and alkaline solution. The filtering device mainly comprises a filtering box and a plurality of partition plates. The plurality of partition plates divide the filtering box into a plurality of filtering cavities. Overflow holes are formed in each partition plate. An overflow pipe is arranged in each filtering cavity. When the liquid level of the alkaline solution in the filtering cavity exceeds the overflow pipe, the oil on the surface of the alkaline solution can enter the overflow pipe. At the same time, part of the alkaline solution enters the next filtering cavity through the overflow hole, and the above steps are repeated to realize the multiple filtering of the alkaline solution.

[0004] In actual use, when the water outlet of the overflow hole is less than the water inlet of the alkaline solution, the liquid level in each filtering cavity gradually becomes the same. At this time, under the action of the partition plate, the thickness of the oil layer in the filtering cavity at the initial position gradually increases. The fixed overflow pipe is not easy to absorb the oil layer with different thicknesses, so that the filtering effect of the filtering device on the oil layer on the surface of the alkaline solution decreases, and thus needs to be improved. SUMMARY

[0005] In order to improve the above problems, the application provides an alkaline solution oil filtering device for a power battery aluminum shell.

[0006] The application provides an alkaline solution oil filtering device for a power battery aluminum shell, which adopts the following technical scheme:

[0007] The alkaline solution oil filtering device for the power battery aluminum shell comprises a box body and a plurality of partition plates. Each partition plate is uniformly arranged in the box body. Each partition plate divides the box body into an input chamber, an output chamber and a plurality of transition chambers. Each transition chamber is arranged between the input chamber and the output chamber. Overflow holes are formed in each partition plate. The vertical height of each overflow hole gradually increases along the conveying direction of the alkaline solution. Filter oil pipelines are arranged in the input chamber, the output chamber and each transition chamber. A lifting assembly for controlling the lifting of the filter oil pipeline and an adjusting assembly for controlling the rotation of the filter oil pipeline are arranged in the input chamber and each transition chamber. The lifting assembly and the adjusting assembly are connected with the corresponding filter oil pipeline. The lifting assembly is connected with the adjusting assembly.

[0008] When the lye needs to be recycled, the worker pours the lye into the input chamber, and when the liquid level in the conveying chamber gradually rises to the position opposite to the port of the oil filtering pipeline, the oil on the surface of the liquid can be discharged through the oil filtering pipeline. When the liquid level rises to the position of the overflow hole of the transition chamber for communicating with the next stage, the lye can enter the adjacent filtering chamber, and after the liquid level is higher than the overflow hole, the oil layer thickness in the input chamber gradually increases. During the rising of the liquid level, the lifting assembly controls the oil filtering pipeline to rise with the liquid level, so that the oil filtering pipeline is in contact with the oil layer on the surface of the lye more stably, which facilitates the oil filtering of the oil filtering pipeline. Meanwhile, during the operation of the lifting assembly, the lifting assembly controls the adjusting assembly, the adjusting assembly is in contact with the corresponding oil filtering pipeline and controls the rotation of the oil filtering pipeline, so that the port of the oil filtering pipeline is immersed in the oil layer more stably, which further improves the stability of the oil filtering pipeline in absorbing the oil on the surface of the lye, thereby further improving the oil filtering efficiency of the lye surface oil layer of the oil filtering device.

[0010] By adopting the above technical scheme, when the liquid level in the input chamber or the transition chamber gradually rises, the lifting assembly starts and drives the connecting pipe to move, and at this time the first corrugated pipe gradually expands. When the second corrugated pipe is in contact with the adjusting assembly, the adjusting assembly can control the rotation of the second corrugated pipe to adjust the inclination of the second corrugated pipe compared with the connecting pipe, so that the second corrugated pipe adapts to the oil layer of different thicknesses, and at this time the oil on the surface of the lye can enter the second corrugated pipe, thereby improving the oil filtering efficiency of the oil filtering pipeline on the oil on the surface of the lye.

[0011] Preferably, the lifting assembly comprises a support and a plurality of floating balls, each floating ball is connected with the support, the support is hollow, and the support is connected with the connecting pipe through a connecting piece.

[0012] By adopting the above technical scheme, when the liquid level inside the input chamber or the filtering chamber gradually rises, under the action of the floating ball and the hollow support, the support can drive the connecting piece to move, and the connecting piece drives the connecting pipe to move, so as to adjust the position of the port of the oil filtering pipeline, which facilitates the oil filtering pipeline to absorb the oil layer on the surface of the lye more stably.

[0013] Preferably, the connecting piece comprises a connecting plate connected with the support and a connecting ring arranged on the side of the connecting plate away from the support, the connecting pipe is provided with a connecting groove, the connecting ring is arranged in the connecting groove, and the connecting plate and the connecting ring are hollow inside.

[0014] By adopting the above technical scheme, when the oil filter pipeline needs to be adjusted, the worker puts the support into the corresponding input chamber or transition chamber, so that the connecting ring is opposite to the connecting groove of the corresponding connecting pipe, and then the connecting ring is clamped into the connecting groove, so that the connecting ring abuts against the inner wall of the connecting groove, to complete the connection between the support and the connecting pipe. In the subsequent movement of the support and the float ball following the liquid level height, under the action of the connecting ring, the support can drive the connecting pipe to move, to realize the function of adjusting the position of the oil filter pipeline following the liquid level height, to provide convenience for the oil filter pipeline to more stably absorb the oil on the surface of the alkali liquor, thereby improving the oil filtering efficiency of the oil filter device on the oil layer on the surface of the alkali liquor.

[0018] By adopting the technical scheme, in the process that the support frame moves along with the liquid level height, the support frame pulls the first pull rope, the first pull rope drives the supporting wheel to rotate, the supporting wheel drives the control wheel to rotate, and the control wheel winds the second pull rope. The second pull rope drives the control plate to rotate. When the liquid level heights of the input chamber, the output chamber and each transition chamber are gradually the same, the control plate is in contact with the second bellows at the corresponding position and drives the corresponding second bellows to rotate, so as to adjust the inclination degree between the second bellows and the corresponding connecting pipe, and the second bellows is convenient for adapting to oil layers with different thicknesses, thereby the oil filter device is convenient for filtering oil more stably. Meanwhile, since the diameters of the supporting wheels in the input chamber and each transition chamber gradually increase, the rotating distances of the supporting wheels in the input chamber and each transition chamber are different, the rotating amplitudes of the control plates are different, so as to control the second bellows to rotate in different ranges, and the second bellows is convenient for adapting to oil layers with different thicknesses.

[0033] The following will be described in detail in combination with the drawings attached to the present specification. Figures 1-2 The present application will be further described in detail.

[0034] The present application discloses a kind of power battery aluminum shell alkali liquid filter oil device. Refer to Figure 1 A kind of power battery aluminum shell alkali liquid filter oil device, including box 1 and several partitions 2, each partition 2 is evenly fixed in box 1. Each partition 2 separates box 1 into input chamber 11, output chamber 12 and several transition chambers 13, each transition chamber 13 is arranged between input chamber 11 and output chamber 12. Overflow hole 21 is formed in each partition 2, and the vertical height of each overflow hole 21 gradually increases along the conveying direction of alkali liquor. Input chamber 11, output chamber 12 and each transition chamber 13 arranged along the length direction of box 1 are a group of filter pieces, and the filter piece is evenly provided with several groups along the width direction of box 1.

[0035] Input chamber 11, output chamber 12 and each transition chamber 13 are provided with filter oil pipeline 3, input chamber 11 and each transition chamber 13 are provided with lifting assembly 4 for controlling the lifting of filter oil pipeline 3 and adjusting assembly 5 for controlling the rotation of filter oil pipeline 3, lifting assembly 4 and adjusting assembly 5 are connected with corresponding filter oil pipeline 3, and lifting assembly 4 is connected with adjusting assembly 5.

[0036] Refer to Figure 1 And Figure 2 Filter oil pipeline 3 includes support pipe 31, first bellow 32, connecting pipe 33 and second bellow 34, support pipe 31 is arranged in corresponding input chamber 11 or corresponding transition chamber 13 along the vertical direction, one end of first bellow 32 is communicated with support pipe 31, the other end is communicated with connecting pipe 33, second bellow 34 is communicated with the end of connecting pipe 33 away from first bellow 32, and second bellow 34 is inclinedly arranged compared with connecting pipe 33.

[0037] The worker puts the alkali solution with oil layer into the input chamber 11, and in the process of gradually rising of the liquid level in the input chamber 11, the lifting assembly 4 starts and drives the connecting pipe 33 to move, and the connecting pipe 33 drives the second bellows 34 to move, at this time, the second bellows 34 arranged obliquely can absorb the oil layer on the surface of the alkali solution. When the liquid level in the input chamber 11 reaches the lowest point of the overflow hole 21 corresponding to it, the alkali solution can enter the adjacent transition chamber 13. In the process of gradually rising of the liquid level in the adjacent transition chamber 13, the lifting assembly 4 in the transition chamber 13 can control the corresponding connecting pipe 33 to move, and the second bellows 34 in the transition chamber 13 can absorb the oil layer on the surface of the alkali solution in the transition chamber 13. When the liquid level in the input chamber 11 and the adjacent transition chamber 13 exceeds the highest point of the overflow hole 21 connected with the input chamber 11, the alkali solution entering the input chamber 11 will carry part of the oil into the adjacent transition chamber 13, reducing the amount of oil layer in the input chamber 11 entering the adjacent transition chamber 13, that is, realizing the filtration of the oil layer. The process of the alkali solution in the transition chamber 13 entering the adjacent transition chamber 13 and the alkali solution in the transition chamber 13 entering the output chamber 12 is also as described above, which will not be repeated here. After the alkali solution in the input chamber 11 and each transition chamber 13, the alkali solution can enter the output chamber 12, at this time, the worker can draw out the alkali solution in the output chamber 12, so as to reuse the filtered alkali solution.

[0038] In the process of working of the lifting assembly 4, the adjusting assembly 5 starts and controls the second bellows 34 at the corresponding position to rotate, so as to change the inclination degree of the second bellows 34. At this time, since the liquid level in the input chamber 11, the output chamber 12 and each transition chamber 13 gradually rises to the same level, and the amount of oil on the surface of the alkali solution entering the adjacent transition chamber 13 or the output chamber 12 is reduced, that is, the thickness of the oil layer in the input chamber 11, each transition chamber 13 and the output chamber 12 gradually decreases, the second bellows 34 after changing the inclination degree can adapt to the oil layer of different thicknesses in the input chamber 11 and each transition chamber 13, so that the second bellows 34 can more stably absorb the oil on the surface of the alkali solution, thereby improving the oil filtration effect of the oil filtration device on the oil on the surface of the alkali solution.

[0039] Referring to Figure 1 , the output chamber 12 is provided with a compensation pipe 121 in the vertical direction, and the vertical height of the compensation pipe 121 is between the highest point of the overflow hole 21 connected with the output chamber 12 and the vertical height of the central axis of the rotating shaft of the control plate 53.

[0040] When the alkali solution in the output chamber 12 is higher than the compensation pipe 121, the compensation pipe 121 can further absorb the oil remaining on the surface of the alkali solution in the output chamber 12, and in the process of absorption, the input of new alkali solution is stopped, so that the worker can draw out the alkali solution in the output chamber 12 which has been filtered, thereby providing convenience for the worker to reuse the filtered alkali solution.

[0041] Reference Figure 1 and Figure 2 The lifting assembly 4 includes a bracket 41 and several floats 42. Each float 42 is fixed to the bracket 41, and the bracket 41 is hollow inside. The bracket 41 is connected to the connecting pipe 33 through a connector.

[0042] The connector includes a connecting plate 43 and a connecting ring 44. The connecting plate 43 is fixed to the bracket 41, and the connecting ring 44 is fixed to the end of the connecting plate 43 away from the bracket 41. A connecting groove 331 is provided on the connecting pipe 33, and the connecting ring 44 is disposed in the connecting groove 331. The connecting plate 43 and the connecting ring 44 are hollow inside.

[0043] When the lifting assembly 4 is needed to adjust the position of the oil filter pipe 3 port, the worker puts the bracket 41 into the corresponding input chamber 11 or the corresponding transition chamber 13, and then aligns the connecting ring 44 with the connecting groove 331 of the corresponding connecting pipe 33, so that the connecting ring 44 is inserted into the corresponding connecting groove 331, thus completing the connection between the bracket 41 and the corresponding oil filter pipe 3.

[0044] Reference Figure 1 In order to improve the stability of the support 41 and float 42 when they move, the inner walls of the input chamber 11 and each transition chamber 13 are provided with guide arc surfaces 6, each float 42 corresponds to a guide arc surface 6, and the float 42 abuts against the corresponding guide arc surface 6.

[0045] Several guide posts 14 are fixed in the input chamber 11 and each transition chamber 13. Each guide post 14 passes through the corresponding bracket 41, and the bracket 41 is slidably connected along the corresponding guide post 14.

[0046] As the liquid level in the input chamber 11 or transition chamber 13 gradually rises, the support 41 and floats 42 move under the action of buoyancy. At this time, the guide column 14 guides the support 41, and the guide arc surface 6 guides each float 42, so that the support 41 and each float 42 move in the set direction, improving the stability of the support 41 and each float 42 during movement. During the movement of the support 41, the support 41 drives the connecting plate 43 to move, the connecting plate 43 then drives the connecting ring 44 to move, and the connecting ring 44 then drives the corresponding connecting pipe 33 to move. When the connecting pipe 33 moves, it can drive the second bellows 34 to move and drive the first bellows 32 to unfold, thus providing convenience for the support 41 to control the movement of the oil filter pipeline 3 more stably.

[0047] Reference Figure 1 and Figure 2The adjustment assembly 5 includes a support wheel 51, a control wheel 52, and a control plate 53. The support wheel 51 and the control wheel 52 are coaxially connected and rotatably connected in the corresponding input chamber 11 or the corresponding transition chamber 13. The control plate 53 is rotatably connected in the corresponding input chamber 11 or the corresponding transition chamber 13, and the vertical height of the central axis of the control plate 53's rotation shaft is higher than the highest point of the overflow hole 21 connected to the output chamber 12, that is, the control plate 53 is located above the overflow hole 21 at its highest position. A first pull rope 54 is wound around the support wheel 51, and the end of the first pull rope 54 away from the support wheel 51 is fixed to the bracket 41. A second pull rope 55 is wound around the control wheel 52, and the end of the second pull rope 55 away from the control wheel 52 is fixed to the control plate 53. The plane where the first pull rope 54 extends from the support wheel 51 is parallel to the plane where the second pull rope 55 extends from the control wheel 52. Furthermore, the diameter of the support wheels 51 in the input chamber 11 and each transition chamber 13 increases progressively along the direction of alkali delivery. When the control plate 53 contacts the second bellows 34 at the corresponding position, the control plate 53 can control the second bellows 34 to rotate.

[0048] Each input chamber 11 and each transition chamber 13 is fixed with a connecting seat 56. A support wheel 51 and a control wheel 52 form a group and correspond to a connecting seat 56. A connecting shaft 57 is rotatably connected to the connecting seat 56. The support wheel 51 and the control wheel 52 are located at opposite ends of the connecting shaft 57, and both the support wheel 51 and the control wheel 52 are coaxially fixed to the connecting shaft 57. A coil spring (not shown in the figure) is provided in the connecting seat 56, and the coil spring is connected to the connecting shaft 57.

[0049] As the support 41 moves with the liquid level, it pulls the first pull rope 54, which in turn drives the support wheel 51 to rotate. The support wheel 51 then drives the control wheel 52 to rotate, and the control wheel 52 winds up the second pull rope 55. The second pull rope 55 drives the control plate 53 to rotate. When the liquid levels in the input chamber 11, output chamber 12, and each transition chamber 13 gradually become the same, the control plate 53 contacts the corresponding second bellows 34 and drives it to rotate. This adjusts the inclination between the second bellows 34 and the corresponding connecting pipe 33, facilitating the adaptation of the second bellows 34 to different oil layers and thus providing a more stable oil filtration system. Simultaneously, because the diameters of the support wheels 51 in the input chamber 11 and each transition chamber 13 increase progressively, the rotation distances of the support wheels 51 in the input chamber 11 and each transition chamber 13 differ, resulting in different rotation amplitudes of the control plate 53. This controls the rotation angles of each second bellows 34 to adapt to different oil layers.

[0050] Reference Figure 1 and Figure 2In order to facilitate the reuse of the second bellows 34, the reset column 7 is arranged in the input chamber 11 and each transition chamber 13, and the reset slope 71 is arranged on the reset column 7, and the reset groove 72 is arranged on the reset slope 71.

[0051] In the process of rotating the support wheel 51 and the control wheel 52, the coil spring is in a compressed state. When the worker draws out the filtered lye in the output chamber 12, the liquid level drops, and at this time, the support 41 and each floating ball 42 in the input chamber 11 and each transition chamber 13 drop. Under the action of the rebound force of the coil spring, the corresponding support wheel 51 and control wheel 52 are automatically reset, that is, the support wheel 51 winds the corresponding first pull rope 54, and the control wheel 52 unwinds the corresponding second pull rope 55, so that the control plate 53 is reset, thereby facilitating the subsequent continuous adjustment of the inclination degree of the second bellows 34.

[0052] In the process of resetting the support 41 and each floating ball 42, the support 41 drives the connecting pipe 33 to move under the transmission action of the connecting plate 43 and the connecting ring 44, so that the first bellows 32 re-contracts, and the second bellows 34 moves towards the reset column 7. When the second bellows 34 contacts the inner wall of the reset groove 72 on the reset slope 71 on the reset column 7, the second bellows 34 can be automatically reset, so as to facilitate the subsequent adjustment of the inclination degree of the second bellows 34. At the same time, the reset groove 72 increases the contact area of the second bellows 34 and the reset column 7, thereby improving the reset stability of the reset column 7 to the second bellows 34.

[0053] Referring to Figure 1 In order to facilitate the movement of the box body 1, universal wheels 8 are arranged at the four corners of the bottom of the box body 1.

[0054] The implementation principle of the alkali lye oil filtering device of the power battery aluminum shell is that the lifting assembly 4 adjusts the position of the oil filtering pipeline 3 according to the actual liquid level height, so that the port of the oil filtering pipeline 3 stably absorbs the oil in the surface layer of the lye, and the lifting assembly 4 controls the adjustment assembly 5 to adjust the inclination degree of the port of the oil filtering pipeline 3 according to the thickness of the oil layer in the input chamber 11 or the transition chamber 13, so as to absorb the oil layer with different thicknesses by the oil filtering pipeline 3, thereby improving the oil filtering efficiency of the oil filtering device.

[0055] The above are the preferred embodiments of the present application, which do not limit the protection scope of the present application, so that: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
