Description

Technical Field

[0001] The present invention relates to the technical field of battery black powder recovery, and particularly to a filtering structure for power battery black powder recovery. Background Art

[0002] Battery black powder recovery is a treatment technology for waste lithium batteries. Its core lies in recycling and reusing the black mixture rich in valuable metals such as lithium, cobalt, nickel, and manganese (i.e., battery black powder) obtained after pre-treating waste batteries through crushing, screening, etc. This technology realizes the efficient recovery of valuable metals through steps such as leaching, separation, and purification, which helps to reduce the dependence on primary mineral resources and environmental pollution.

[0003] The filter press plays a key role in battery black powder recovery. Its principle is mainly based on pressure filtration technology. By applying pressure, the solid particles in the battery black powder mixture are effectively separated from the liquid. During the pressure filtration process, the black powder mixture is injected into a closed filter chamber. After applying pressure, the liquid part passes through the filter cloth on the filter plate and is discharged, while the solid particles are intercepted by the filter cloth to form a filter cake. In the process of battery black powder recovery, when the filter press completes the solid-liquid separation, the filter cake remains on the filter cloth, and the filter cloth is fixed on the filter plate. To remove the filter cake, the filter plates need to be separated one by one. The prior art has achieved a simple and effective linkage mechanism by connecting chains between adjacent filter plates. When the pulling plate trolley drags a set of filter plates at the end, the chains will drive the adjacent filter plates to move in sequence, causing the filter plates to gradually separate from each other, thus exposing the filter cake. Under the action of gravity or with the assistance of workers' patting, the filter cake will fall off the filter cloth, facilitating subsequent collection and processing. To reduce the occupied space, the pulling plate trolley sometimes needs to make multiple round trips to continuously transport the corresponding filter plates.

[0004] The above-mentioned filter press has deficiencies in operation efficiency and space utilization. Some filter cakes need to be patted manually to make them fall off, which not only consumes manpower but also increases the operation complexity. At the same time, the pulling plate trolley requires a large draggable space, resulting in low space utilization rate. Especially when dealing with a large number of filter plates, this problem is particularly prominent. These deficiencies limit the automation degree and overall efficiency of the filter press in battery black powder recovery. Summary of the Invention

[0005] The purpose of the present invention is to provide a filtering structure for power battery black powder recovery, which solves the technical problem that the pulling plate trolley requires a large draggable space when dealing with a large number of filter plates, resulting in low space utilization rate.

[0010] As a further solution of the present invention: Each group of moving components includes a second conveyor belt in contact with the guide rail, a side roller coaxially and fixedly connected to the corresponding driving wheel, and a moving roller rotatably connected to the inside of the housing.

[0013] As a further solution of the present invention: each group of the limiting components includes a fixing plate fixedly connected to the outer shell.

[0017] The beneficial effects of the present invention:

[0018] 1. In the present invention, the rotation of the motor drives the driving wheel to rotate. The rotation of the driving wheel drives the separation conveyor belt to move, and then drives the push block to move. The push block drives the hanging plate and the connected plate body to move, realizing the separation and transportation effects of adjacent plate bodies. When the driving wheel rotates, it drives the side roller to rotate. The side roller drives the second transmission belt to move. The second transmission belt drives the moving roller to move. The moving roller contacts the guide rail, enabling the second transmission belt to move along the guide rail, and then driving the outer shell and its connected components to move. Moreover, the moving roller is smaller than the radius of the driving wheel, thus ensuring that the movement speed of the second transmission belt is much smaller than that of the separation conveyor belt, ensuring that when the outer shell moves, the push block can quickly drag the plate body to achieve separation. The present invention can realize the rapid separation and rapid blanking of the filter plates, and at the same time requires a smaller dragging space, reducing the occupied space.

[0019] 2. In the present invention, multiple groups of protrusions for generating vibrations are fixedly arranged at the lower end of each vibration plate. When the plate body moves, the protrusions will squeeze the vibration rollers, thereby playing a role in guiding the up-and-down movement. When the plate body vibrates, the first spring will be intermittently compressed, realizing the relative movement of the guide post and the guide sleeve, and cooperating with the plate body to complete the vibration effect, improving the blanking speed.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0031] Please refer to Figure 1-8 As shown in the figure, the present invention is a filtering structure for recycling black powder of power batteries, including a frame 1. A hydraulic device 10 is fixedly arranged on one side of the frame 1. The output end of the hydraulic device 10 is fixedly provided with a push plate 11, and the hydraulic device 10 can push the push plate 11 to move. The inner side of the frame 1 is fixedly connected with a guide rail 2. A plurality of groups of filter plates 3 are slidably matched on the guide rail 2. Each group of filter plates 3 includes a plate body 301 and a vibration assembly 305 for facilitating the vibration of the plate body 301. Filter tanks 302 are opened on both sides of the plate body 301, and through holes are opened in the middle of the filter tanks 302, so that the filter tanks 302 on both sides of the plate body 301 are communicated through the through holes, and the input materials will enter the filter tanks 302 of the adjacent plate body 301 along the through holes. Ear plates 303 are fixedly connected to both sides of the plate body 301. The vibration assembly 305 is arranged on the ear plates 303 and is slidably matched with the guide rail 2. Each group of vibration assemblies 305 includes a guide post 3051 fixedly connected to the ear plate 303. The guide post 3051 is set as a column with edges, such as Figure 5As shown, the guide post 3051 is a column with a cross-section. A guide sleeve 3053 is slidably matched on the ear plate 303, and a limit opening 3055 is provided at the upper end of the guide sleeve 3053 to slide with the guide post 3051. A first spring 3052 is fixedly arranged on the guide post 3051, and the other end of the first spring 3052 is fixedly arranged with the guide sleeve 3053. The first spring 3052 is responsible for maintaining the distance between the upper end of the guide post 3051 and the guide sleeve 3053. When the plate body 301 vibrates, the first spring 3052 will be intermittently compressed to achieve relative movement between the guide post 3051 and the guide sleeve 3053. A guide roller 3056 that cooperates with the guide rail 2 is rotatably connected to the guide sleeve 3053, and a groove is provided on one side of the guide rail 2, and the guide roller 3056 can move along the groove.

[0032] A feed pipe 9 is fixedly arranged on the other side of the frame 1, and water outlet pipes 306 are fixedly arranged on both sides of the lower end of each group of plate bodies 301. A material conveyor belt 7 and two groups of water troughs 5 are arranged at the bottom of the frame 1. Figure 3 As shown, the water trough 5 is located on both sides of the material conveyor belt 7, and the position of the water trough 5 corresponds to the position of the water outlet pipe 306. A discharge port 6 cooperating with the material conveyor belt 7 is provided on one side of the frame 1, and the material conveyor belt 7 is responsible for transporting the filter cake to the discharge port 6. A water extraction pipe 8 connected to the water trough 5 is fixedly provided on one side of the frame 1, and the water extraction pipe 8 is responsible for extracting the water inside the water trough 5.

[0033] The guide rail 2 is provided with a feeding mechanism 4. Figure 2 As shown, the unloading mechanism 4 includes a shell 405 covering the upper end of the plate body 301. The inner side of the shell 405 is provided with a moving component 403 for driving the shell 405 to move, a driving component 402 for shifting the filter plate 3 to one side, a driving component 401 for driving the driving component 402 and the moving component 403, a vibration plate 406 for making the moving plate body 301 vibrate, and a limiting component 404 for limiting. The driving component 402, the moving component 403, the limiting component 404, and the vibration plate 406 are all provided in two groups, and are symmetrically arranged on the inner side of the shell 405. Each group of ear plates 303 is rotatably provided with a vibration roller 304 that matches the vibration plate 406. The lower end of each group of vibration plates 406 is fixedly provided with multiple groups of protrusions for inducing vibration. When the plate body 301 moves, the protrusions will squeeze the vibration roller 304, thereby playing a role in guiding the up and down movement.

[0034] Each driving assembly 402 includes a separating conveyor belt 4022 and two driving wheels 4021 rotatably connected to the inner side of the housing 405. The separating conveyor belt 4022 is disposed on the two driving wheels 4021 in a matching manner. A hanging plate 3054 is fixedly connected to each guiding sleeve 3053. A plurality of pushing blocks 4023 for pushing the hanging plate 3054 to move are fixedly arranged at equal intervals on the separating conveyor belt 4022. The rotation of the driving wheel 4021 drives the movement of the separating conveyor belt 4022, and then drives the movement of the pushing block 4023. The pushing block 4023 drives the hanging plate 3054 and the plate body 301 connected thereto to move, realizing the separation and transportation effects of adjacent plate bodies 301. A cushion plate 12 is fixedly connected to the inside of the frame 1 away from the hydraulic device 10. A through hole communicating with the feeding pipe 9 is opened in the inner side of the cushion plate 12. The size of the cushion plate 12 is the same as that of the plate body 301, ensuring that the driving assembly 402 can transport the filter plate 3 at the end.

[0035] Each moving assembly 403 includes a second conveyor belt 4033 in contact with the guide rail 2, a side roller 4031 fixedly connected coaxially with the corresponding driving wheel 4021, and a moving roller 4032 rotatably connected to the inner side of the housing 405. The diameter of the side roller 4031 is smaller than that of the driving wheel 4021. As Figure 7 shown, in an embodiment, the diameter of the driving wheel 4021 is 8 - 10 cm, and the diameter of the side roller 4031 is 2 - 4 cm, ensuring that the rotational speed of the side of the driving wheel 4021 is less than the rotational speed of the side roller 4031. At least two moving rollers 4032 are provided, and the horizontal heights of all the moving rollers 4032 are the same. The second conveyor belt 4033 is disposed on the side roller 4031 and the corresponding moving roller 4032 in a matching manner. When the driving wheel 4021 rotates, it drives the rotation of the side roller 4031. The side roller 4031 drives the movement of the second conveyor belt 4033. The second conveyor belt 4033 drives the movement of the moving roller 4032. The moving roller 4032 is in contact with the guide rail 2, so that the second conveyor belt 4033 can move along the guide rail 2, and then drives the movement of the housing 405 and its connecting components.

[0036] A rail beam 13 extending along the direction of the guide rail 2 is fixedly connected to the frame 1. A positioning sliding sleeve 15 is slidably engaged with the rail beam 13. A lifting seat 14 is disposed between the positioning sliding sleeve 15 and the housing 405. The lifting seat 14 can drive the housing 405 to move upward, so that the vibrating plate 406, the separating conveyor belt 4022 and the pushing block 4023 are all away from the filter plate 3.

[0037] In a specific embodiment, as Figure 7As shown, each set of limit components 404 includes a fixing plate 4041 fixedly connected to the housing 405. A support column 4042 is slidably fitted on the fixing plate 4041. The upper end of the support column 4042 is rotatably connected to a limit roller 4043 for pressing against the bottom of the guide rail 2. The limit roller 4043 can move along the pressing guide rail 2. The bottom of the support column 4042 is fixedly connected to a driving plate 4044. A threaded rod 4045 is threadedly connected to the driving plate 4044. The upper end of the threaded rod 4045 is rotatably connected to the fixing plate 4041. When all the filter plates 3 are separated, the threaded rod 4045 can be rotated. The threaded rod 4045 drives the limit roller 4043 to move downward, so that a gap appears between the limit roller 4043 and the bottom of the guide rail 2. Then, the housing 405 is lifted by the lifting seat 14, so that the vibrating plate 406, the separation conveyor belt 4022 and the pushing block 4023 are all away from the filter plate 3, and the limit roller 4043 contacts the bottom of the guide rail 2 again, thereby facilitating the staff to push the housing 405 to move along the guide rail 2 to complete the reset of the blanking mechanism 4.

[0038] In another specific embodiment, as Figure 8 shown, each set of limit components 404 includes a fixing plate 4041 fixedly connected to the housing 405. A support column 4042 is slidably fitted on the fixing plate 4041. The upper end of the support column 4042 is rotatably connected to a limit roller 4043 for pressing against the bottom of the guide rail 2. A second spring 4046 is fixedly arranged on the support column 4042. The other end of the second spring 4046 is fixedly connected to the fixing plate 4041. The second spring 4046 is used to maintain the relative position between the fixing plate 4041 and the support column 4042. When all the filter plates 3 are separated, the housing 405 is lifted by the lifting seat 14, so that the second spring 4046 is compressed, the vibrating plate 406, the separation conveyor belt 4022 and the pushing block 4023 are all away from the filter plate 3, and the limit roller 4043 contacts the bottom of the guide rail 2 again, thereby facilitating the staff to push the housing 405 to move along the guide rail 2 to complete the reset of the blanking mechanism 4.

[0039] The driving component 401 includes a motor 4011 fixedly connected to the housing 405. The output end of the motor 4011 is fixedly connected to a transmission shaft 4012. Two sets of driving wheels 4013 are coaxially fixedly connected to the transmission shaft 4012. One side of the driving wheel 4021 is coaxially connected to a driven wheel 4015. The position of each driving wheel 4013 corresponds to the position of the driven wheel 4015 on the same side. A first transmission belt 4014 is arranged on the mutually cooperating driving wheel 4013 and driven wheel 4015. The rotation of the motor 4011 drives the transmission shaft 4012 to rotate. The transmission shaft 4012 drives the first transmission belt 4014 to move. The first transmission belt 4014 drives the driven wheel 4015 to rotate, and then drives the driving wheel 4021 to rotate, completing the driving effect on the driving wheel 4021.

[0040] Working principle of the present invention: The rotation of the motor 4011 drives the rotation of the transmission shaft 4012. The transmission shaft 4012 drives the movement of the first transmission belt 4014. The first transmission belt 4014 drives the rotation of the driven wheel 4015, and then drives the rotation of the driving wheel 4021, completing the driving effect on the driving wheel 4021. The rotation of the driving wheel 4021 drives the movement of the separation conveyor belt 4022, and then drives the movement of the push block 4023. The push block 4023 drives the hanging plate 3054 and the connected plate body 301, realizing the separation and transportation effects of adjacent plate bodies 301;

[0041] When the driving wheel 4021 rotates, it drives the rotation of the side roller 4031. The side roller 4031 drives the movement of the second transmission belt 4033. The second transmission belt 4033 drives the movement of the moving roller 4032. The moving roller 4032 contacts the guide rail 2, enabling the second transmission belt 4033 to move along the guide rail 2, and then driving the movement of the housing 405 and its connecting components. And the moving roller 4032 is smaller than the radius of the driving wheel 4021, so as to ensure that the movement speed of the second transmission belt 4033 is much lower than that of the separation conveyor belt 4022, ensuring that when the housing 405 moves, the push block 4023 can quickly drag the plate body 301 to achieve separation.

[0042] At the lower end of each vibration plate 406, a plurality of protrusions for generating vibration are fixedly arranged. When the plate body 301 moves, the protrusions will squeeze the vibration roller 304, thus playing a role in guiding the up and down movement. When the plate body 301 vibrates, the first spring 3052 will be intermittently compressed, realizing the relative movement of the guide post 3051 and the guide sleeve 3053, and cooperating with the plate body 301 to complete the vibration effect and improve the blanking speed.

[0043] When all the filter plates 3 are separated, the threaded rod 4045 can be rotated. The threaded rod 4045 drives the limit roller 4043 to move downward, making a gap appear between the limit roller 4043 and the bottom of the guide rail 2. Then, the housing 405 is lifted by the lifting seat 14, so that the vibration plate 406, the separation conveyor belt 4022 and the push block 4023 are all away from the filter plate 3, and the limit roller 4043 contacts the bottom of the guide rail 2 again, facilitating the staff to push the housing 405 to move along the guide rail 2 to complete the reset of the blanking mechanism 4.

[0044] The above has described a specific embodiment of the present invention in detail, but the content described is only the preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
