Description

Technical Field

[0001] This invention belongs to the field of waste treatment and recycling, specifically a waste battery grading and recycling equipment. Background Technology

[0002] A storage battery is a rechargeable electrical energy storage device that achieves multiple charge-discharge cycles through reversible electrochemical reactions. However, as the service life increases, the active materials inside gradually degrade and the electrolyte performance deteriorates, eventually losing its energy storage capacity and becoming a waste battery. In order to achieve resource recycling and reduce environmental pollution, waste storage batteries need to be professionally crushed and recycled.

[0003] A patent document with announcement number CN221209353U discloses a crushing and sorting device for recycling waste storage batteries, including a mounting base, a collection tank, a valve, a housing, rotating rods, a feed hopper, a filter screen, a cam, etc.; the collection tank is installed on the top of the mounting base, the valve is provided at the bottom of the collection tank, the housing is slidably connected to the top of the collection tank, a spring is connected between the housing and the collection tank, and two rotating rods are rotatably connected inside the collection tank, and the two rotating rods are connected by a flat belt drive.

[0004] In traditional waste battery crushing and recycling processes, the separation and recycling of electrolyte and plastic waste usually rely on screen separation devices. After crushing, the waste is filtered through a screen to remove electrolyte, and then the crushed material on the screen is pushed and collected by a feeding mechanism. However, the porous structure of the screen in this scheme makes it easy for the crushed material to rub against the screen surface, get caught, or even get stuck during the parallel pushing process. This not only accelerates screen wear and shortens the life of the device, but also causes screen hole blockage and reduces sorting efficiency. In addition, the independent waste feeding mechanism often leads to a dispersed equipment layout and an excessively large footprint, increasing the construction and maintenance costs of the production line.

[0005] Therefore, the present invention provides a waste battery grading and recycling device to solve the problems mentioned in the background art. Summary of the Invention

A crushing box is installed above the screening box. The screening box includes a frame fixedly installed below the crushing box and a screening and turning mechanism movably installed inside the frame. The crushing and feeding area of ​​the crushing box is smaller than the screening area of ​​the screening and turning mechanism. Two feeding areas are provided at the bottom of the recycling box. A sorting cavity is opened inside the recycling box. A sorting mechanism is movably installed inside the sorting cavity. The sorting mechanism includes a rotating mechanism one and a rotating mechanism two symmetrically and rotatably installed at the center of the sorting chamber. When the rotating mechanism one and the rotating mechanism two rotate simultaneously and the rotating mechanism one is in an obtuse angle state, the crushed electrolyte is fed through the rotating mechanism one and a set of corresponding feeding areas. When the rotating mechanism one and the rotating mechanism two rotate simultaneously and the rotating mechanism two is in an obtuse angle state, the crushed plastic shell waste is fed through the rotating mechanism two and another set of corresponding feeding areas.

[0007] Preferably, a connecting groove is provided inside the upper end of the sorting cavity, and the sorting cavity is connected to the inside of the frame through the connecting groove. A first discharge pipe and a second discharge pipe are symmetrically installed below the recycling box.

[0008] Preferably, two feeding troughs are symmetrically distributed at the bottom of the sorting cavity, and the two feeding troughs are respectively connected to the corresponding feeding pipe one and feeding pipe two.

[0013] Preferably, two guide elastic plates are fixedly installed on the side of the telescopic guide plate two away from the telescopic guide plate one, and the other ends of the two guide elastic plates are fixedly connected to the inner wall of the sorting cavity.

[0014] Preferably, the telescopic guide plate includes an outer plate and an inner plate slidably installed inside the outer plate. The lower end of the inner plate is connected to the rotating column. A connecting piece is installed on the lower side of the guide elastic sheet, and the connecting piece is connected to the bottom side of the inner plate.

[0015] Preferably, the screening and flipping mechanism includes a bottom frame block rotatably installed inside the frame body. Buffer springs are installed at the four upper corners of the bottom frame block. A screening plate is installed above the multiple buffer springs.

The crushed electrolyte is fed through rotating mechanism one and a set of corresponding feeding areas. The flipping screening and flipping mechanism flips the originally upward-facing screen structure downwards. At this time, the crushed plastic waste is fed through rotating mechanism two and another set of corresponding feeding areas. The flipping screening and flipping mechanism in this device prevents the plastic fragments from rubbing against the screen surface, snagging, or even getting stuck during the parallel pushing feeding process. This avoids accelerated screen wear, shortened device life, and screen hole blockage, which reduces sorting efficiency. Attached Figure Description

Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] Example 1: As Figures 1-7 As shown, the waste battery grading and recycling equipment of this embodiment includes a recycling box 1 and a screening box 3 installed above the recycling box 1. A crushing box 2 is installed above the screening box 3. The screening box 3 includes a frame 31 fixedly installed below the crushing box 2 and a screening and flipping mechanism 32 movably installed inside the frame 31. The crushing and feeding area of ​​the crushing box 2 is smaller than the screening area of ​​the screening and flipping mechanism 32. Two feeding areas are provided at the bottom of the recycling box 1. A sorting cavity 11 is opened inside the recycling box 1. A sorting mechanism 14 is movably installed inside the sorting cavity 11. The sorting mechanism 14 includes a rotating mechanism 4 and a rotating mechanism 5 symmetrically and rotatably installed at the center of the sorting chamber 11. When the rotating mechanism 4 and the rotating mechanism 5 rotate simultaneously and the rotating mechanism 4 is in an obtuse angle state, the crushed electrolyte is fed through the rotating mechanism 4 to a set of corresponding feeding areas. When the rotating mechanism 4 and the rotating mechanism 5 rotate simultaneously and the rotating mechanism 5 is in an obtuse angle state, the crushed plastic shell waste is fed through the rotating mechanism 5 to another set of corresponding feeding areas.

[0022] Specifically, in this device, waste batteries are placed inside the crushing chamber 2. Through the crushing structure inside the crushing chamber 2, the batteries are crushed into electrolyte and plastic fragments, which are then fed downwards. The electrolyte continues to be fed into the sorting chamber 11 via the screening and turning mechanism 32. At this time, rotating mechanisms 4 and 5 rotate simultaneously, with rotating mechanism 4 at an obtuse angle. The crushed electrolyte is fed through rotating mechanism 4 and a corresponding feeding area. When plastic fragments are needed, rotating mechanisms 4 and 5 are driven to rotate simultaneously again, so that rotating mechanism 5 is at an obtuse angle. Then, the screening and turning mechanism 32 is turned over. This causes the originally upward-facing screen structure to flip downwards. At this time, the crushed plastic shell waste is fed into another set of corresponding feeding areas through the rotating mechanism 2 5. In this device, the flipping screening mechanism 32 structure prevents the plastic shell fragments from scraping, snagging, or even getting stuck on the screen surface during the parallel pushing feeding process. This avoids accelerating screen wear, shortening the device's lifespan, and causing screen hole blockage, which reduces sorting efficiency. In addition, the sorting mechanism 14 is set inside the sorting chamber 11. The recycling of electrolyte and plastic shell waste can be achieved in one chamber, reducing the floor space and not increasing the construction and maintenance costs of the production line.

[0023] like Figures 2-5 and Figure 7 As shown, a connecting groove 111 is provided inside the upper end of the sorting cavity 11. The sorting cavity 11 is connected to the inside of the frame 31 through the connecting groove 111. A discharge pipe 12 and a discharge pipe 2 13 are symmetrically installed below the recycling box 1.

[0024] The upper end of the sorting chamber 11 has a connecting groove 111. The sorting chamber 11 is connected to the inside of the frame 31 through the connecting groove 111. The bottom of the recycling box 1 is symmetrically equipped with a first discharge pipe 12 and a second discharge pipe 13.

[0025] Two feeding troughs 16 are symmetrically distributed at the bottom of the sorting chamber 11. The two feeding troughs 16 are respectively connected to the corresponding feeding pipe 12 and feeding pipe 2 13.

[0026] Displacement grooves 15 are provided on both sides of the inner top of the sorting cavity 11. The sorting mechanism 14 achieves rotation through the two displacement grooves 15.

[0027] The rotating mechanism 4 includes a rotating column 43 rotatably installed at the bottom of the sorting chamber 11 and a telescopic guide plate 42 fixedly installed above the rotating column 43. A displacement column 41 is fixedly installed at the upper end of the telescopic guide plate 42. Two limiting columns 411 are fixedly installed at both ends of the displacement column 41. Both limiting columns 411 are slidably installed inside the two corresponding displacement grooves 15.

[0028] The rotating mechanism 25 includes a rotating column 253 rotatably installed at the bottom of the sorting cavity 11 and a telescopic guide plate 252 fixedly installed above the rotating column 253. A displacement column 251 is fixedly installed at the upper end of the telescopic guide plate 252. The displacement column 251 and the displacement column 141 are components made of the same structure. The displacement column 251 is slidably connected to the two displacement grooves 15.

[0029] The screening and flipping mechanism 32 includes a bottom frame block 321 rotatably installed inside the frame 31. Buffer springs 323 are installed at the four upper corners of the bottom frame block 321. A screening plate 322 is installed above the multiple buffer springs 323. Rotating shafts 3211 are fixedly installed on both sides of the center position of the bottom frame block 321. The two rotating shafts 3211 are rotatably installed inside the frame 31. The outer side of the end of a set of rotating shafts 3211 is connected to a motor on the outside of the frame 31. Slots are also provided on both sides of the bottom frame block 321. Telescopic positioning columns 3212 are inserted into the inside of the slots and are fixedly installed inside the frame 31.

[0030] Specifically, when the electrolyte and plastic waste are crushed and fed, they fall above the screening plate 322. The electrolyte falls into the sorting chamber 11 through the screening and turning mechanism 32. At this time, driven by the motor, the rotating column 43 and the rotating column 53 rotate in the same direction until the telescopic guide plate 42 is at an obtuse angle. The fed electrolyte falls into the feeding area formed by the telescopic guide plate 42 and the inside of the sorting chamber 11 at this obtuse angle. Finally, it passes through the corresponding feeding trough 16 and the feeding pipe 13. For the electrolyte collection process, a vibration motor is installed on the lower side of the screening plate 322. This motor drives the screening plate 322 to vibrate, thus more efficiently causing the electrolyte to fall and separating the electrolyte adhering to the plastic waste shell above the screening plate 322. Multiple buffer springs 323 buffer the vibration force of the screening plate 322, thereby increasing the service life of the entire device. After the electrolyte recovery is complete, when it is necessary to collect the plastic waste shell above the screening plate 322, multiple telescopic positioning columns 3212 are first driven to retract, causing... The end is no longer inserted into the bottom frame block 321. Instead, the entire telescopic positioning post 3212 after the retracted end is placed inside the frame 31. Then, the rotating shaft 3211 is driven by the motor to rotate, causing the bottom frame block 321, the screening plate 322, and multiple buffer springs 323 to flip together inside the frame 31. This allows multiple plastic waste shells above the screening plate 322 to be discharged. Before this, the rotating mechanism 1 4 and rotating mechanism 2 5 are driven by the motor to rotate in the same direction simultaneously until the telescopic guide plate 2... When 52 is in an obtuse angle state, the unloaded plastic waste shell will fall into the unloading area formed by the telescopic guide plate 2 52 and the sorting cavity 11 in this obtuse angle state. Finally, it will be discharged and collected through the corresponding unloading groove 16 and unloading pipe 12. During the rotation of the rotating mechanism 1 4 and the rotating mechanism 2 5, the limiting posts 411 set at both ends of the displacement column 1 41 and the displacement column 2 51 are always slidably installed inside the corresponding displacement groove 15, and the telescopic guide plate 1 42 and the telescopic guide plate 2 52 will extend and retract to a certain extent for the applicable length.

[0031] Example 2: Figure 6 As shown in the first embodiment, another embodiment of the present invention is as follows: the second telescopic guide plate 52 and the first telescopic guide plate 42 are components with the same structure. The width of the second telescopic guide plate 52 is smaller than the width of the first telescopic guide plate 42. The widths of both the second telescopic guide plate 52 and the first telescopic guide plate 42 are greater than the width of the screening and flipping mechanism 32.

[0032] Two guide elastic plates 54 are fixedly installed on the side of the telescopic guide plate 2 52 away from the telescopic guide plate 1 42, and the other ends of the two guide elastic plates 54 are fixedly connected to the inner wall of the sorting cavity 11.

[0033] The telescopic guide plate 52 includes an outer plate 521 and an inner plate 522 that is slidably installed inside the outer plate 521. The lower end of the inner plate 522 is connected to the rotating column 53. A connecting piece 541 is installed on the lower side of the guide elastic piece 54, and the connecting piece 541 is connected to the bottom side of the inner plate 522.

[0034] Specifically, the length and width of the screening plate 322 are both smaller than the length and width of the sorting cavity 11. Therefore, the electrolyte being fed will be in the feeding area formed by the obtuse angle state of the rotating mechanism 4 and the inside of the sorting cavity 11. When the rotating mechanism 4 rotates from the obtuse angle state to the acute angle state, it will scrape off the electrolyte on the side wall of the electrolyte feeding area to a certain extent, allowing it to be discharged from the feeding pipe 13. To avoid the rotation of the rotating mechanism 5 scraping the electrolyte in the side wall of the feeding area during sorting and feeding, the width of the telescopic guide plate 252 is set to be smaller than the width of the telescopic guide plate 42. When rotating mechanism 4 rotates, rotating mechanism 5 will follow suit, changing from an acute angle to an obtuse angle. The screen plate 322 and bottom frame block 321 are flipped to allow the vibrating de-liquidated plastic waste shells to be discharged. Because multiple waste materials are flipped and discharged simultaneously, they may collide with each other, thus changing their descent path. In this device, two guide elastic plates 54 are provided on the side of the narrower telescopic guide plate 52. When the telescopic guide plate 52 is at an obtuse angle, the two guide elastic plates 54 are stretched, forming an area for discharging the plastic waste shells together with the telescopic guide plate 52. The guide plate 54 guides the collection of waste materials and prevents them from impacting the inner wall of the sorting chamber 11. When the rotating mechanism 52 is in an acute angle state, the two guide elastic plates 54 are in an elastic contraction state, the same as in the stretched state. The two guide elastic plates 54 will never contact the inner wall of the sorting chamber 11, that is, they will not come into contact with the electrolyte that may remain on the inner wall of the sorting chamber 11, thus avoiding corrosive damage from repeated contact with the electrolyte. The setting of the two guide elastic plates 54 can ensure that the telescopic guide plate 52 does not scrape the electrolyte on the wall that originally belonged to the electrolyte feeding area when rotating for sorting. However, since the telescopic guide plate 52 is composed of an outer plate 521 and an inner plate 522, when the rotating mechanism 5 rotates, the inner plate 522 will extend out inside the outer plate 521. This will cause a large hole to appear on the side of the inner plate 522 after the guide elastic sheet 54 is stretched. Therefore, a connecting piece 541 is provided on the lower side of the guide elastic sheet 54. The connecting piece 541 is fixedly connected to the lower side of the inner plate 522. When the rotating mechanism 5 is in an obtuse angle state, the guide elastic sheet 54 can be stretched adaptively, and a large hole will not appear on the side of the inner plate 522.

[0035] Working Principle: In this device, waste batteries are placed inside the crushing chamber 2. The crushing structure inside the chamber 2 breaks the batteries into electrolyte and plastic fragments, which are then fed downwards. The electrolyte is fed into the sorting chamber 11 via the screening and flipping mechanism 32. At this time, rotating mechanisms 4 and 5 rotate simultaneously, with rotating mechanism 4 at an obtuse angle. The crushed electrolyte is fed through rotating mechanism 4 and a corresponding feeding area. When plastic fragments are needed, rotating mechanisms 4 and 5 are driven to rotate simultaneously again. When rotating mechanism 5 is at an obtuse angle, the screening and flipping mechanism 32 flips the originally upward-facing screen structure downwards. At this point, the crushing process... The plastic waste is fed into another set of corresponding feeding areas via rotating mechanism 25. The rotating screening mechanism 32 in this device prevents the plastic fragments from rubbing against the screen, snagging, or even getting stuck during the parallel pushing feeding process, thus avoiding accelerated screen wear, shortened device lifespan, and screen blockage, which reduces sorting efficiency. Furthermore, the device incorporates a sorting mechanism 14 within the sorting chamber 11, allowing for the recycling of both electrolyte and plastic waste within a single chamber, reducing floor space and minimizing production line construction and maintenance costs. Since the length and width of the screening plate 322 are smaller than those of the sorting chamber 11, the fed electrolyte will be within the rotating mechanism 4. In the obtuse angle state and the feeding area formed inside the sorting chamber 11, when the rotating mechanism 4 rotates from the obtuse angle state to the acute angle state, it will scrape off the electrolyte on the side wall of the electrolyte feeding area to a certain extent, so that it can be discharged from the feeding pipe 13. In order to avoid the rotation of the rotating mechanism 5 scraping the electrolyte in the side wall of the feeding area during sorting and feeding, the width of the telescopic guide plate 252 is set to be smaller than the width of the telescopic guide plate 42. When the rotating mechanism 4 rotates, the rotating mechanism 25 will rotate accordingly and change from the acute angle state to the obtuse angle state. The plastic waste shell after vibration and liquid removal is fed out by flipping the screening plate 322 and the bottom frame block 321. Since multiple wastes are flipped and fed out at the same time, there may be mutual collisions, which may change the descent path. In this device, two guide elastic plates 54 are provided on the side of the narrower telescopic guide plate 52. When the telescopic guide plate 52 is at an obtuse angle, the two guide elastic plates 54 are stretched, forming an area for feeding plastic waste shells with the telescopic guide plate 52, guiding the collection of waste and preventing waste from impacting the inner wall of the sorting cavity 11. When the rotating mechanism 52 changes to an acute angle, the two guide elastic plates 54 are in an elastic contraction state, the same as in the stretched state. The two guide elastic plates 54 will never contact the inner wall of the sorting cavity 11, that is, they will not come into contact with the electrolyte that may remain on the inner wall of the sorting cavity 11, avoiding corrosive damage from repeated contact with the electrolyte. Through the setting of the two guide elastic plates 54,The telescopic guide plate 52 can prevent the electrolyte on the wall of the electrolyte feeding area from being scraped during rotation and sorting. However, since the telescopic guide plate 52 is composed of an outer plate 521 and an inner plate 522, the inner plate 522 extends outward from inside the outer plate 521 when the rotating mechanism 5 rotates. This can cause a large void to appear on the side of the inner plate 522 after the guide elastic sheet 54 is stretched. Therefore, a connecting piece 541 is provided on the lower side of the guide elastic sheet 54. The connecting piece 541 is fixedly connected to the lower side of the inner plate 522. When the rotating mechanism 5 is in an obtuse angle state, the guide elastic sheet 54 can be stretched adaptively, and there will be no large void on the side of the inner plate 522.
