Description

Technical Field

[0001] The utility model relates to the technical field of battery recycling, in particular to a screening device for battery recycling. Background Art

[0002] With the continuous increase in the demand for batteries in the industry, the amount of waste batteries has also increased. If not recycled, they will become a large amount of waste, causing a burden on waste treatment and landfill. By recycling batteries, the generation of waste can be reduced and the pressure on waste treatment facilities can be alleviated.

[0003] Battery recycling involves crushing and pulverizing waste batteries for better subsequent treatment. These devices usually use mechanical crushing, cutting, etc. to break the batteries, ensuring that the substances inside the batteries can be fully exposed, separating the electrolyte inside the batteries from the crushed materials, and then performing subsequent recycling operations on the crushed materials to achieve the full utilization of battery materials.

[0004] In the prior art, screening devices for battery recycling usually adopt mechanical vibration screening. A sieve mesh is provided inside the device, and the battery scraps and electrolyte are separated by vibration. The battery scraps gradually move from the sieve mesh to the scrap processing end, and the electrolyte is located below the sieve mesh and gradually flows to the electrolyte processing end. After separation, the battery scraps are processed and recycled. However, in the above operations, due to the different sizes of the battery scraps after crushing, it is very easy for the battery scraps to fall into the electrolyte through the sieve mesh under the action of vibration screening, resulting in the mixing of scraps during electrolyte recycling and affecting the recycling rate of battery recycling. Summary of the Utility Model

[0005] To solve the above technical problems, the utility model uses a sieve mesh to separate the crushed materials and the electrolyte, and the partition sieve can vibrate and screen the crushed materials and the electrolyte. The specific technical solutions are as follows:

[0006] A screening device for battery recycling includes an inclined screening frame and a sieve mesh installed at the open port of the screening frame. A driving member for generating vibration is arranged outside the screening frame, and a liquid guiding member is installed on the inner wall of the screening frame and below the sieve mesh. The liquid guiding member includes an inclined plate installed along the inclined side wall of the screening frame and a partition sieve installed above the bottom end of the inclined plate and having an end that abuts against the inclined surface of the inclined plate and forms another branch relative to the inclined plate. The mesh number of the partition sieve is smaller than that of the sieve mesh.

[0007] Preferably, an arc-shaped plate is arranged at the lower part of the inclined plate where the partition sieve is located.

[0008] Preferably, one end of the arc-shaped plate is tangent to the inclined surface of the partition sieve.

[0009] Preferably, a gap for the electrolyte to flow through is arranged at one end of the partition sieve facing the inclined plate.

[0010] Preferably, the cross-section of the separation sieve is square or wavy.

[0011] Preferably, the screening frame includes a vibrating housing installed at the outer edge of the inclined plate, a support frame installed at the bottom end of the vibrating housing, and a buffer member installed between the support frame and the vibrating housing.

[0012] It can be seen from the above technical solutions that the present utility model has the following beneficial effects:

[0013] In the present utility model, the broken materials and the electrolyte are separated by the sieve mesh. The broken materials that fall onto the inclined plate through the sieve mesh move downward with the electrolyte under vibration until the broken materials fall onto the separation sieve from the bottom end of the inclined plate along with the vibration. The separation sieve can vibrate and screen the broken materials and the electrolyte. The electrolyte flows into the arc-shaped plate through the gap between the separation sieve and the inclined plate. The arc-shaped plate guides and collects the electrolyte. The sieve mesh and the separation sieve collect broken materials of different sizes. After the broken materials and the electrolyte are collected, they can be processed and recycled later, avoiding the mixing of the electrolyte and the broken materials, which affects the utilization rate of battery recycling. At the same time, it also avoids the accumulation of broken materials at the electrolyte, so as to prevent blockage. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The following will describe the present utility model in detail with reference to the accompanying drawings and specific embodiments. Before elaborating on the technical solutions of each embodiment of the present utility model, the nouns and terms involved will be explained. In this specification, components with the same name or the same reference numeral represent similar or identical structures, and are for illustrative purposes only.

[0019] Such as Figure 1 and Figure 2As shown in the figure, a screening device for battery recycling includes an inclined screening frame 10 and a screen 20 installed at the open port of the screening frame 10. A driving member 40 is provided outside the screening frame 10. A liquid guiding member 30 is installed on the inner wall of the screening frame 10 and below the screen 20. The liquid guiding member 30 includes an inclined plate 301 installed along the inclined side wall of the screening frame 10 and a separating screen 303 installed above the bottom end of the inclined plate 301 and whose end is attached to the inclined surface of the inclined plate 301 and forms another branch relative to the inclined plate 301. The mesh number of the separating screen 303 is smaller than that of the screen 20. Among them, after the battery is crushed, it forms crushed materials and electrolyte. The crushed materials and electrolyte fall onto the screen 20 at the upper end of the screening frame 10. The driving member 40 drives the screening frame 10 to vibrate, and the screen 20 vibrates along with the screening frame 10, causing the crushed materials to gradually fall along the inclined surface of the screen 20. The electrolyte falls from the screen 20 to the surface of the inclined plate 301. With the vibration of the inclined surface of the screen 20, the residual electrolyte in the crushed materials gradually falls through the screen 20 due to vibration and falls onto the inclined plate 301 until the crushed materials fall out from the bottom end of the screen 20 with vibration. The crushed materials can be used for subsequent processing and recycling. The electrolyte flows out from the bottom end of the inclined plate 301, thus realizing the recycling of the electrolyte. For the crushed materials passing through the screen 20, they gradually fall onto the separating screen 303 along the vibrating inclined plate 301. Since the mesh number of the separating screen 303 is smaller than that of the screen 20, the crushed materials will not fall onto the inclined plate 301 again on the separating screen 303. The vibration of the separating screen 303 discharges the crushed materials together with the crushed materials on the screen 20 for subsequent processing and recycling; the slope of the inclined plate 301 can be greater than that of the screen 20, which helps to increase the flow rate of the electrolyte and reduce the vibration time of the electrolyte on the inclined plate 301.

[0020] As Figure 2 shown, an arc-shaped plate 302 is provided at the lower part of the inclined plate 301 where it is located relative to the separating screen 303. Among them, the arc-shaped plate 302 facilitates guiding the electrolyte on the surface of the inclined plate 301. At the same time, it also ensures the distance between the arc-shaped plate 302 and the separating screen 303, reducing the height of the electrolyte splash under the vibration effect, so as to avoid contacting the crushed materials on the separating screen 303 again, resulting in a decrease in the electrolyte recovery rate. At the same time, it also affects the heat required for the evaporation of the electrolyte when recycling the crushed materials. The residual electrolyte in the crushed materials fully falls through the vibration of the separating screen 303.

[0021] As Figure 2 shown, one end of the arc-shaped plate 302 is tangent to the inclined surface of the separating screen 303. The arc-shaped plate 302 can make the electrolyte flow better under the vibration effect. The separating screen 303 is collinear with the inclined surface of the inclined plate 301, which helps the crushed materials in the electrolyte to fall onto the separating screen 303, so as to avoid the crushed materials getting stuck at the junction between the separating screen 303 and the inclined plate 301.

[0022] One end of the separation sieve 303 facing the inclined plate 301 is provided with a gap for the electrolyte to flow through, and the gap is used to discharge the electrolyte in the inclined plate 301, while the broken materials fall onto the separation sieve 303.

[0023] There are various ways for the separation sieve 303, and the specific implementation methods are as follows:

[0024] Embodiment 1:

[0025] As Figure 2 shown, the cross-section of the separation sieve 303 is square, and the gaps of the separation sieve 303 are square. When the electrolyte and the broken materials fall to the gaps of the separation sieve 303, the electrolyte flows from the square gaps onto the arc-shaped plate 302, while the broken materials are blocked by the separation sieve 303 and gradually fall onto the separation sieve 303 with the vibration. The vibrating separation sieve 303 promotes the electrolyte remaining on the broken materials to fall onto the arc-shaped plate 302.

[0026] Embodiment 2:

[0027] As Figure 3 shown, the cross-section of the separation sieve 303 is wavy, and the gap formed at the junction of the separation sieve 303 and the inclined plate 301 is arched. The electrolyte flows from the arch into the arc-shaped plate 302, while the broken materials are blocked by the separation sieve 303. The broken materials are blocked by the separation sieve 303 and gradually fall onto the separation sieve 303 with the vibration. The vibrating separation sieve 303 promotes the electrolyte remaining on the broken materials to fall onto the arc-shaped plate 302. The length direction of the wavy shape of the separation sieve 303 is the same as the falling direction of the broken materials, which helps the broken materials to fall, and at the same time makes the electrolyte flow to the bottom end of the wavy shape, reducing the contact between the broken materials and the electrolyte.

[0028] As Figure 1 and Figure 2 shown, the screening frame 10 includes a vibrating housing 101 installed on the outer edge of the inclined plate 301, a support frame 102 installed at the bottom end of the vibrating housing 101, and a buffer member 103 installed between the support frame 102 and the vibrating housing 101. Among them, the buffer member 103 can be realized by using a spring connection to achieve the vibration screening effect of the vibrating housing 101. In addition, the buffer member 103 can also use a rubber isolator, and the rubber isolator is installed between the vibrating housing 101 and the support frame 102 to ensure the vibration of the vibrating housing 101 and reduce the force transmission from the vibrating housing 101 to the support frame 102.

[0029] As Figure 1 and Figure 2As shown in the figure, a baffle 104 is also installed at the top of the vibrating housing 101. The baffle 104 is used to block the top ends of the screen 20 and the inclined plate 301 to prevent the broken materials and the electrolyte from overflowing outside the top end of the vibrating housing 101. A mounting seat 105 is fixedly installed on the inner wall of the vibrating housing 101. The screen 20 is fixed to the vibrating housing 101 through the mounting seat 105. Among them, the mounting seat 105 is of a multi-section type and is arranged along the inclined surface of the vibrating housing 101. The mounting seat 105 installs the screen 20 on the vibrating housing 101 by means of bolts, which is convenient for subsequent replacement of the screen 20.

[0030] As Figure 1 and Figure 2 shown in the figure, the driving member 40 includes an eccentric flywheel 403 rotatably installed on the outer wall of the screening frame 10 and a motor 401 for driving the eccentric flywheel 403 to rotate. By driving the rotation of the eccentric flywheel 403 by the motor 401, the vibrating housing 101 is driven to achieve a vibrating effect after the eccentric flywheel 403 rotates. Among them, a belt group 402 is arranged between the motor 401 and the eccentric flywheel 403. The belt group 402 includes belt pulleys installed on the shafts of the motor 401 and the eccentric flywheel 403, and a belt is sleeved between the two belt pulleys. The motor 401 transmits torque to the eccentric flywheel 403 through the belt pulleys and the belt. In addition, the output shaft of the motor 401 can also be fixed to the shaft of the eccentric flywheel 403 through a coupling, or two sets of meshing gears can be sleeved on the eccentric flywheel 403 and the motor 401 to transmit torque.

[0031] When recycling the battery broken materials as described above, first, the battery broken materials and the electrode liquid are dropped onto the top of the screen 20. As the eccentric flywheel 403 drives the vibrating housing 101 to vibrate, the broken materials gradually fall along the inclined surface of the screen 20, and the electrolyte falls from the screen 20 to the surface of the inclined plate 301 until the broken materials fall out from the bottom end of the screen 20 with the vibration. The broken materials can be used for subsequent processing and recycling. The electrolyte flows out from the bottom end of the inclined plate 301, and the recycling of the electrolyte can be realized. For the broken materials passing through the screen 20, they gradually fall onto the separation screen 303 along the vibrating inclined plate 301. The broken materials passing through the separation screen 303 and the broken materials passing through the screen 20 are discharged for subsequent processing and recycling.

Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention should fall within the protection scope determined by the claims of the present invention.
