Description

Technical Field

[0001] The utility model relates to the technical field of battery recycling devices, in particular to a powder recycling and filtering auxiliary device. Background Art

[0002] Discarded lithium batteries contain a large amount of mixed powder that can be recycled. Recycling it can reduce the pollution of discarded batteries to the environment and improve economic benefits. The recycling of lithium battery powder generally requires processes such as crushing, magnetic separation, air separation, gravity separation, and screening. Part of the powder generated during the entire processing process will be scattered into the surrounding environment. The powder in the air is generally brought into the dust collector by a negative pressure system for collection. This not only can additional powder suspended in the air be obtained, increasing the total output of recycled powder, but also ensuring a good working environment. However, the powder collected by the dust collector in the prior art is often mixed with some large particles of debris, resulting in a decrease in the recovery purity of the air-suspended powder. Utility Model Content

[0003] In view of the above-mentioned deficiencies in the prior art, the utility model provides a powder recovery and filtering auxiliary device, which solves the problem in the prior art that the powder collected in the dust collector is easily mixed with large particles.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] Provided is a powder recovery and filtering auxiliary device, comprising a shell, the shell being a cylindrical body with an opening at the top, and a filter screen arranged inside the shell for dividing the inner space of the shell into a particle space and a powder space; the shell is detachably connected to a discharge port of a dust collector through a connecting hoop arranged on the outer wall of the shell;

[0006] A particle discharge port communicated with the particle space and a powder discharge port communicated with the powder space are fixed on the shell; a vibration generating device for vibrating the filter screen is arranged in the powder space.

[0007] The beneficial effects of the utility model are as follows: the scheme adds a filtering auxiliary device to the dust collector discharge port, and the filter screen inside it can filter and screen the materials collected by the dust collector again, and the large particles that cannot pass through the filter screen will flow out from the particle discharge port above the filter screen, and the powder that can pass through the filter screen will flow out from the powder discharge port. The purpose of separating the powder from the large particles mixed in the powder and improving the recovery purity of the air-suspended powder is achieved. The vibration generating device can make the filter screen vibrate to avoid clogging of the filter screen, and help large particles move from the center to the edge of the shell to facilitate entering the particle discharge port.

[0008] Furthermore, the shell located in the particle space includes a contact portion and a corrugated portion, the inner wall of the contact portion is tightly fitted with the outer wall of the dust collector discharge port, and the connecting hoop is arranged outside the contact portion; the contact portion and the corrugated portion are both made of flexible materials.

[0009] The beneficial effects of the above technical solution are as follows: the contact portion has a buffering and sealing function, and the corrugated portion has a shock absorbing function, thereby preventing the vibration of the filter from being transmitted to the dust collector and affecting the normal operation of the dust collector.

[0010] Furthermore, a circular conveying plate is arranged in the powder space and is fixed obliquely to the inner wall of the shell, and the powder discharge port is arranged at the lowest position of the conveying plate installation position. After entering the powder space, the powder falls onto the conveying plate, and is discharged from the powder discharge port along the inclined conveying plate, and then is collected by an external powder collecting device.

[0011] Furthermore, a shock-absorbing support is fixed to the bottom of the shell, and the shock-absorbing support includes a bottom plate 1 and a bottom plate 2 connected by a spring; a plurality of grooves are evenly arranged on the lower surface of the bottom plate 1, and a plurality of protrusions extending into the grooves are arranged on the upper surface of the bottom plate 2; and the vibration generating device is fixed on the bottom plate 1.

[0012] The beneficial effects of the above technical solution are as follows: the provision of a shock-absorbing support can help the housing connect to the ground, and provide certain support to the housing through the ground, increase the supporting points of the housing, relieve the fixing pressure at the connection hoop, and reduce the probability of the housing being separated from the dust collector due to vibration. The spring can also reduce shock to prevent the vibration from being transmitted to the ground.

[0013] Furthermore, the vibration generating device is located below the conveying plate; two connecting rods are fixedly connected to the vibration generating device, the top ends of the connecting rods extend out of the conveying plate and are fixedly connected to the bottom of the filter screen; and the outer wall of the connecting rods is in close contact with the conveying plate, thereby preventing powder from leaking out from the connection between the conveying plate and the connecting rods.

[0014] Furthermore, the vibration generating device is electrically connected to the controller.

DETAILED DESCRIPTION

[0021] The specific implementation methods of the utility model are described below to facilitate technical personnel in this technical field to understand the utility model, but it should be clear that the utility model is not limited to the scope of the specific implementation methods. For ordinary technical personnel in this technical field, as long as various changes are within the spirit and scope of the utility model defined and determined by the attached claims, these changes are obvious, and all utility model creations using the concept of the utility model are protected.

[0022] like Figure 1 As shown, this scheme is to add a powder recovery and filtering auxiliary device at the dust collector discharge port 21, which includes a shell 1, which is a cylindrical body with an open top, and a filter screen 3 is arranged inside the shell 1 to divide the internal space of the shell 1 into a particle space 7 and a powder space 8; the shell 1 is detachably connected to the dust collector discharge port 21 through a connecting hoop 6 arranged on the outer wall of the shell 1; the shell 1 is fixed with a particle discharge port 13 connected to the particle space 7 and a powder discharge port 14 connected to the powder space 8. The filter screen 3 can filter and screen the materials collected by the dust collector again to improve the recovery purity of the air-suspended powder.

[0023] A vibration generating device 4 for vibrating the filter screen 3 is provided in the powder space 8. The vibration generating device 4 can vibrate the filter screen 3 to prevent the filter screen 3 from being blocked, and helps large particles to move from the center to the edge of the housing 1 so as to enter the particle outlet 13. The material will have horizontal displacement while oscillating, and the powder will easily pass through the filter screen 3 when vibrated, and the particles will easily disperse toward the edge of the filter screen 3 when vibrated. When they are dispersed to the particle outlet 13, the particles can be separated from the device.

[0024] Among them, the dust collector 2 is not the subject of protection of the present utility model. Its working principle is roughly as follows: the surrounding air is sucked into the dust collector 2 from the dust collector feed port 22 by the fan through the air duct. A separator that can separate gas and powder is arranged inside the machine. The discharger discharges the collected dust from the dust collector discharge port 21 and is collected by an external collection device. The air purified and dust-removed by the dust collector 2 is discharged into the atmosphere by the fan, which will not be repeated here.

[0025] refer to Figure 2 The housing 1 located in the particle space 7 includes a contact portion 15 and a corrugated portion 11. The inner wall of the contact portion 15 is tightly fitted with the outer wall of the dust collector discharge port 21. The connecting hoop 6 is sleeved outside the contact portion 15. The contact portion 15 and the corrugated portion 11 are both made of flexible materials. The contact portion 15 has a buffering and sealing function, and the corrugated portion 11 has a shock absorbing function to prevent the vibration of the filter 3 from being transmitted to the dust collector 2 and affecting the normal operation of the dust collector 2.

[0026] The material of the contact portion 15 and the corrugated portion 11 can be rubber. The connecting hoop 6 can clamp the outer shell 1 on the dust collector 2, and the flexible contact portion 15 can be used as a buffer material to prevent the clamping force of the connecting hoop 6 from damaging the dust collector 2 or causing local deformation of the material. The clamping force makes it easy for the flexible contact portion 15 to fit tightly with the dust collector discharge port 21, which can ensure the connection and sealing between the outer shell 1 and the dust collector 2 and prevent the material from leaking into the air. The corrugated portion 11 is equivalent to a section of rubber bellows, which has a certain elasticity and vibration absorption capacity. When subjected to external vibration or impact, the rubber bellows will undergo elastic deformation to absorb and disperse the vibration energy, thereby reducing the impact of the vibration on the upper dust collector 2 and preventing the vibration below from being transmitted upward.

[0027] A circular conveying plate 12 is provided in the powder space 8 and is fixed obliquely to the inner wall of the housing 1. A powder discharge port 14 is provided at the lowest position of the conveying plate 12. After entering the powder space 8, the powder falls onto the conveying plate 12, and is discharged from the powder discharge port 14 along the inclined conveying plate 12, and then is collected by an external powder collecting device.

[0028] In one embodiment of the present scheme, a shock-absorbing support 5 is fixed to the bottom of the housing 1, and the shock-absorbing support 5 includes a bottom plate 1 51 and a bottom plate 2 52 connected by a spring 53; a plurality of grooves 55 are evenly provided on the lower surface of the bottom plate 1 51, and a plurality of protrusions 54 extending into the grooves 55 are provided on the upper surface of the bottom plate 2 52; and the vibration generating device 4 is fixed on the bottom plate 1 51. The cooperation of the grooves 55 and the protrusions 54 can limit the horizontal position of the bottom plate 1 51 to a certain extent, preventing it from shaking left and right significantly, and preventing the housing 1 from shaking significantly, thereby further preventing the housing 1 from detaching from the dust collector 2 due to shaking. The provision of the shock-absorbing support 5 can help the housing 1 connect to the ground, and provide a certain support to the housing 1 through the ground, increase the support points of the housing 1, relieve the fixing pressure at the connection hoop 6, and reduce the probability of the housing 1 detaching from the dust collector 2 due to vibration. And the spring 53 can reduce shock to prevent the vibration from being transmitted to the ground.

[0029] The vibration generating device 4 is located below the conveying plate 12; two connecting rods 41 are fixedly connected to the vibration generating device 4, the top ends of the connecting rods 41 extend out of the conveying plate 12 and are fixedly connected to the bottom of the filter screen 3; the outer wall of the connecting rod 41 is in close contact with the conveying plate 12. Powder is prevented from leaking from the connection between the conveying plate 12 and the connecting rod 41. Powder falling on the filter screen 3 is prone to clogging after long-term use. The vibration generating device 4 can make the powder fall by vibrating the filter screen 3, and prevent the material from getting stuck on the sieve holes of the filter screen 3.

[0030] The vibration generating device 4 can be a vibrator, which has an eccentric hammer and a motor as a power source installed inside. The eccentric hammer can convert the original rotational motion into an oscillating motion. The oscillating motion is directly transmitted from the connecting rod 41 to the filter screen 3, making the screening more complete. The oscillating motion can also be transmitted from the connecting rod 41 to the conveying plate 12, so that the powder can slide down to the powder discharge port 14 more smoothly.

[0031] The vibration generating device 4 is electrically connected to the controller. During use, the filter screen will be quickly covered with powder, which affects the screening of fine powder. In view of this situation, the vibration generating device 4 is electrically connected to the controller, and the controller controls the vibration generating device 4 to start at a set time interval, giving the filter screen 3 a vibration force and shaking off the powder on the filter screen 3, thereby realizing automatic control. The controller can be a controller with a PLC component.

[0032] refer to Figure 3The connecting hoop 6 includes a hinged clamping block 1 63 and a clamping block 2 64; a screw 61 passing through the clamping block 1 63 is provided at the free end of the clamping block 2 64, and a butterfly nut 62 bolted to the screw 61 is provided above the clamping block 1 63. After loosening the screw 61 and the nut 62, the outer shell 1 and the dust collector discharge port 21 can be disassembled. The clamping force of the connecting hoop 6 can be adjusted by adjusting the fixed position of the nut 62. The inner walls of the clamping block 1 63 and the clamping block 2 64 form a circle, and the size of the circle matches the outer shell 1; the clamping block 1 63 and the clamping block 2 64 are jointly sleeved on the outer wall of the outer shell 1.

[0033] In summary, this solution can separate powder from large particles mixed in the powder, collect the required powder material, and improve the recovery purity of air-suspended powder.
