Description

Technical Field

[0001] The present invention relates to the technical field of lead-acid battery recycling. More specifically, the present invention relates to a crushing and disassembling device for lead-acid battery regeneration with explosion-proof protection. Background Art

[0002] The working voltage of lead-acid batteries is stable, the operating temperature and current range are wide, the storage performance is good, and the cost is low. They are widely used in various fields. Most of the waste lead-acid battery treatment devices on the market cannot achieve fine separation and collection of waste materials. The workload of workers is large, and it is difficult to quickly transfer the collected crushed waste materials and timely replace the collection tank;

[0003] For example, in the patent document with the publication number CN112246323B, an automated crushing and fine separation treatment device for waste lead-acid batteries can change the overall horizontal inclination angle of the movable feeding plate and pour the crushed waste materials into different waste material collection tanks to avoid the waste materials falling into the wrong collection tank, realizing the functions of fine separation and collection of waste materials, facilitating the quick transfer of the collected crushed waste materials, and timely replacing the collection tank for combined use with the separation treatment device;

[0004] However, in the above patent document, the crushing tooling is open. A small number of lead-acid batteries are prone to explosion risks during crushing due to incomplete discharge. And during feeding, when the number of single feeding is large, lead-acid batteries will fall at the opening, and it is impossible to expand the protection range during feeding. During crushing, the feeding port is closed to reduce the oxygen content in the crushing area and improve the safety of crushing;

[0005] Moreover, the crushed slag after crushing still needs to be subjected to distributed regeneration treatment. When separating the electrolyte in the crushed slag, a small amount of electrolyte remains inside the crushed slag, and it is impossible to shake out the small amount of electrolyte inside when transferring the crushed slag collection box, accelerating the subsequent recovery treatment of the crushed slag and improving the recovery efficiency;

[0006] In view of the above technical defects, a solution is provided now. Summary of the Invention

[0007] To overcome the above-mentioned defects of the prior art, the present invention provides a crushing and disassembling device for lead-acid battery regeneration with explosion-proof protection.

[0008] To achieve the above object, the present invention provides the following technical solution: A crushing and disassembling device for lead-acid battery regeneration with explosion-proof protection, including a feeding cylinder and a crushing tooling arranged below it. Two symmetrically arranged brackets are arranged below the crushing tooling, and a discharging assembly for discharging battery fragments is arranged between the two brackets. An explosion-proof assembly for preventing battery explosion is arranged inside the feeding cylinder;

[0009] The discharging assembly includes two sets of limiting sleeves slidably sleeved above the bracket. A collecting box is fixedly installed between the corresponding two sets of limiting sleeves. A plurality of rotating shafts are rotatably arranged inside the collecting box through bearings. Stirring members are arranged on the outer walls of the rotating shafts. Both ends of the rotating shafts extend outside the collecting box and are fixedly connected with side gears. A rack is commonly meshed and connected to the bottoms of the multiple side gears on the same side, and the rack is fixedly connected with the bracket;

[0010] One side of the bottom of the collecting box is rotatably provided with a baffle through a bolt.

[0011] Further, a cross plate is arranged in the middle of the bracket. Feeding plates are symmetrically arranged on both sides of the cross plate. The feeding plates are inclined downward from the side close to the cross plate to the side far from the cross plate.

[0012] Further, a plurality of cross cylinders are rotatably arranged between the two cross plates. An inclined cylinder is rotatably arranged between the two feeding plates, and the baffle is mutually attached to the cross cylinders and the inclined cylinder.

[0013] Further, one end of a threaded rod is threadedly connected to the bottom of one of the limiting sleeves. One end of the threaded rod is provided with a first motor, and the other end of the threaded rod is connected to the bracket. A limiting rod is slidably arranged at the bottom of the other limiting sleeve, and the limiting rod is connected to the bracket.

[0014] Further, the explosion-proof assembly includes a first drive shaft and a second drive shaft rotatably arranged above the feeding cylinder. The end of the first drive shaft extends outside the feeding cylinder and is provided with a second motor.

[0015] Further, the end of the second drive shaft extends outside the feeding cylinder and is provided with a first gear. A second gear is meshed and connected to the outside of the first gear. A connecting shaft is arranged at the center of the second gear.

[0016] Further, the connecting shaft is rotatably connected to the feeding cylinder. The connecting shaft and the first drive shaft are connected through a transmission member. Protective plates are arranged on the outer walls of the first drive shaft and the second drive shaft inside the feeding cylinder.

[0017] Among them, the crushing and disassembling method for the regeneration of lead-acid batteries includes the following steps:

[0018] Put in lead-acid batteries: The two protective plates are in an open state, and the lead-acid batteries are put into the feeding cylinder;

[0019] Crush lead-acid batteries: Control the two protective plates to move closer to each other and seal the upper part of the feeding cylinder to reduce the entry of external air. Start the crushing tooling to crush and disassemble the lead-acid batteries;

[0020] Separate and discharge crushed slag: Filter the electrolyte in the crushed slag through the baffle plate. During transfer, the stirring part stirs the crushed slag in the collection box, allowing a small amount of the electrolyte to seep into the interior of the collection pool. When the bottom of the baffle plate is closely attached to the inclined cylinder, the discharge of the crushed slag is completed.

[0021] Technical effects and advantages of the present invention:

[0022] 1. In the present invention, by controlling the second motor to drive the first drive shaft to rotate, the two protective plates are in an open state, preventing the lead-acid battery from falling during the input process. After the input is completed, the second motor is controlled to rotate in the reverse direction, causing the two protective plates to approach each other and seal the feed cylinder, reducing the entry of external air and lowering the explosion risk, thereby jointly improving the safety of equipment use.

[0023] 2. In the present invention, by controlling the first motor to drive the threaded rod to rotate, another set of collection boxes is moved below the crushing tooling. At the same time, the side gears on both sides of the collection box are engaged with the rack, realizing the rotation of the rotating shaft, and cooperating with the stirring part to stir the crushed slag in the collection box, shaking a small amount of the electrolyte into the interior of the collection pool. When the baffle plate at the bottom of the collection box moves above the blanking plate, the crushed slag in the collection box is discharged. During the transfer process, the battery slag and the electrolyte are thoroughly separated, accelerating the recycling efficiency of the lead-acid battery. At the same time, different types of lead-acid batteries are classified and recycled, improving the practicality of equipment use and further enhancing the recycling efficiency.

[0024] 3. Before crushing the lead-acid battery, the present invention not only expands the protection range during the feeding of the lead-acid battery, but also seals the feed cylinder during crushing to reduce the entry of external air and lower the explosion risk. After crushing, the crushed slag and the electrolyte are separated, and the collection box is quickly replaced. Through the mutual cooperation of the three stages before, during, and after crushing, the crushing and disassembling efficiency of the recycling and reuse of lead-acid batteries is jointly improved.

Detailed implementation manners

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. 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 creative efforts shall fall within the protection scope of the present invention.

[0033] Embodiment 1: Please refer to Figure 1 - Figure 6 As shown, for the problem in the prior art that when transferring the collection box of the broken slag, a small amount of electrolyte inside it cannot be shaken out to speed up the later recovery and treatment of the broken slag of the lead-acid battery, the following solution can be adopted;

[0034] In this embodiment, a crushing and disassembling device for the regeneration of lead-acid batteries with explosion-proof protection includes a feed cylinder 1 and a crushing tooling 2 arranged below it. Two symmetrically arranged supports 3 are arranged below the crushing tooling 2. A discharging component 6 for collecting and discharging the battery broken materials is arranged between the two supports 3. An explosion-proof component 4 for preventing the battery from breaking and exploding is arranged inside the feed cylinder 1;

[0035] It should be explained here that: The crushing tooling 2 is mainly composed of a drive system and crushing rollers. The two mutually cooperating crushing rollers are driven by the drive system to complete the crushing of the lead-acid battery. The drive system is a drive motor, which belongs to the prior art and will not be elaborated here too much. It only needs to have the crushing function for the above-mentioned lead-acid battery;

[0036] Please refer to Figure 1 - Figure 4As shown in the figure, the unloading assembly 6 includes two groups of limit sleeves 61 slidably sleeved above the bracket 3. A collection box 63 is fixedly installed between the corresponding two groups of limit sleeves 61. A plurality of rotating shafts 64 are rotatably arranged inside the collection box 63 through bearings. Stirring members 65 are arranged on the outer walls of the rotating shafts 64. Both ends of the rotating shafts 64 extend outside the collection box 63 and are fixedly connected with side gears 66. A rack 67 is commonly meshed and connected to the bottoms of the multiple groups of side gears 66 on the same side. The rack 67 is fixedly connected to the bracket 3;

[0037] It should be supplemented here that: rollers are provided at the contact points between the limit sleeves 61 and the bracket 3, so as to reduce the friction between the limit sleeves 61 and the bracket 3 and ensure the flexibility of the movement of the limit sleeves 61 above the bracket 3; the stirring members 65 are composed of multiple groups of stirring plates and are evenly distributed above the rotating shafts 64 to stir the broken slag of lead-acid batteries inside the collection box 63 and vibrate out and recover a small amount of electrolyte above it;

[0038] Please refer to Figure 1 As shown in the figure, a baffle is rotatably arranged at one side of the bottom of the collection box 63 through a bolt, and the baffle is of a mesh structure. The electrolyte in the broken slag inside the collection box 63 is filtered through the baffle to realize the separation and recovery of the two;

[0039] Please refer to Figure 1 - Figure 4 As shown in the figure, one end of a threaded rod 62 is threadedly connected to the bottom of a limit sleeve 61. One end of the threaded rod 62 is provided with a first motor, and the other end of the threaded rod 62 is connected to the bracket 3. A limit rod is slidably arranged at the bottom of the other limit sleeve 61, and the limit rod is connected to the bracket 3; the first motor is connected to the bracket 3;

[0040] Then the battery broken slag after crushing and disassembling enters the inside of the collection box 63. The electrolyte is filtered through the collection box 63. When the lead-acid battery inside the feeding cylinder 1 is completely crushed and disassembled, control the first motor to drive the threaded rod 62 to rotate, move the other group of collection boxes 63 below the crushing tooling 2. At the same time, the side gears 66 on both sides of the collection box 63 are meshed with the rack 67 to realize the rotation of the rotating shaft 64, and cooperate with the stirring members 65 to stir the broken slag in the collection box 63, so that a small amount of electrolyte therein seeps into the collection pool 5 to complete the recovery of the remaining electrolyte and accelerate the later recovery and treatment of the lead-acid battery broken slag;

[0041] Please refer to Figure 1 - Figure 4As shown, a cross plate 682 is provided in the middle of the support 3. Feeding plates 681 are symmetrically arranged on both sides of the cross plate 682. The feeding plates 681 are inclined downward from the side close to the cross plate 682 to the side far from the cross plate 682. A plurality of cross cylinders 683 are rotatably arranged between the two cross plates 682, and an inclined cylinder 684 is rotatably arranged between the two feeding plates 681. And the baffle is in close contact with the cross cylinder 683 and the inclined cylinder 684;

[0042] Then when the baffle at the bottom of the collection box 63 moves above the feeding plate 681, due to gravity, the bottom of the baffle closely adheres to the inclined cylinder 684, so as to discharge the broken slag inside the collection box 63. During the transfer process, the battery slag and electrolyte are completely separated, the recycling efficiency of lead-acid batteries is accelerated, and at the same time, different types of lead-acid batteries are classified and recycled to further improve the recycling efficiency;

[0043] Embodiment 2: Please refer to Figure 1 、 Figures 2 - 6 As shown, for the problem that when loading lead-acid batteries, the protection range cannot be expanded, the feeding port cannot be closed during crushing, the oxygen content in the crushing area is reduced, and explosion is prevented, the following solutions can be adopted;

[0044] The explosion-proof component 4 in this embodiment includes a first drive shaft 42 and a second drive shaft 43 rotatably arranged above the feeding cylinder 1. The end of the first drive shaft 42 extends outside the feeding cylinder 1 and is provided with a second motor. The end of the second drive shaft 43 extends outside the feeding cylinder 1 and is provided with a first gear 45. A second gear 46 is meshed and connected to the outside of the first gear 45. A connecting shaft 44 is arranged at the center of the second gear 46. The connecting shaft 44 is rotatably connected to the feeding cylinder 1. The connecting shaft 44 and the first drive shaft 42 are connected by a transmission member. Protection plates 41 are arranged on the outer walls of the first drive shaft 42 and the second drive shaft 43 located inside the feeding cylinder 1, and the two protection plates 41 are symmetrically arranged;

[0045] Then the lead-acid battery is put into the inside of the feeding cylinder 1. At this time, the two protection plates 41 are in an open state to expand the protection range and prevent the lead-acid battery from falling during the input process; after the input is completed, control the two protection plates 41 to move closer to each other and seal the feeding cylinder 1 to reduce the entry of external air, reduce the risk of explosion, and improve the safety of equipment use;

[0046] It should be supplemented here that: the transmission member includes two transmission wheels. One transmission wheel is fixedly connected to the outer wall of the first drive shaft 42, and the other transmission wheel is fixedly connected to the outer wall of the connecting shaft 44. The two transmission wheels are connected by a conveyor belt;

[0047] As can be seen from Embodiment 1 and Embodiment 2 of the present invention: Before crushing the lead-acid battery, not only the protection range during the feeding of the lead-acid battery is expanded, but also the feeding cylinder 1 is sealed during crushing to reduce the entry of external air, reduce the risk of explosion, and after crushing, the crushed slag and electrolyte are separated, and the collection box 63 is quickly replaced. Through the mutual cooperation of the three stages before, during, and after crushing, the crushing and disassembling efficiency of the recycling and reuse of lead-acid batteries is jointly improved, and the safety of the device during use is improved;

[0048] Working principle: When the present invention is in use, first, the lead-acid battery is put into the interior of the feeding cylinder 1. At this time, the second motor controls the rotation of the first drive shaft 42, and the two protective plates 41 are in an open state to prevent the lead-acid battery from falling during the feeding process; after the feeding is completed, the second motor is controlled to rotate in the reverse direction, so that the two protective plates 41 approach each other and seal the feeding cylinder 1 to reduce the entry of external air and reduce the risk of explosion; through the explosion-proof component 4, not only the protection range is expanded during feeding to prevent the lead-acid battery from falling during feeding, but also the top of the feeding cylinder 1 is sealed during disassembly and crushing to reduce the explosion probability and improve the safety of equipment use;

[0049] Next, the battery crushed slag after crushing and disassembling enters the interior of the collection box 63. The electrolyte is filtered through the collection box 63. When the lead-acid battery inside the feeding cylinder 1 is completely crushed and disassembled, the first motor is controlled to drive the threaded rod 62 to rotate, and another set of collection boxes 63 is moved below the crushing tooling 2. At the same time, the side gears 66 on both sides of the collection box 63 are meshed with the rack 67 to realize the rotation of the rotating shaft 64, and cooperate with the stirring member 65 to stir the crushed slag in the collection box 63, so that a small amount of the electrolyte seeps into the collection pool 5. When the bottom baffle of the collection box 63 moves above the blanking plate 681, due to gravity, the bottom of the baffle closely adheres to the inclined cylinder 684, thereby discharging the crushed slag inside the collection box 63. During the transfer process, the battery slag and the electrolyte are completely separated, the recycling efficiency of the lead-acid battery is accelerated, and at the same time, different types of lead-acid batteries are classified and recycled, improving the practicability of equipment use and further improving the recycling efficiency.
