Description

Technical Field

[0001] The utility model relates to the technical field of battery recycling and crushing, in particular to a lead-acid battery recycling and crushing device. Background Art

[0002] Lead-acid batteries have relatively low production costs and are safe and reliable to use, and are widely used in various industries, which also leads to a large number of waste lead-acid batteries generated every year. With the increasing demand for resources, in the production process of lead, recycling and regenerating lead from waste lead-acid batteries has more environmental protection and resource development advantages compared with traditional direct mining and smelting of ore lead.

[0003] The patent document with the application number CN202022860838.1 discloses a preliminary crushing device for dry battery recycling. When in use, through the crushing roller and multiple groups of crushing teeth on its surface, the rapid tearing and crushing of dry batteries are realized. With the cooperation of the feed hopper, the batch crushing of dry batteries is realized, and the crushing efficiency is relatively high. Through the filter screen inclined inside the discharge box body, the rapid filtration of the crushed dry battery residues is realized. At the same time, the residues that do not pass through the filter screen roll into the feed opening at the bottom end of the lifting pipe under the action of gravity, and are transported back to the feed hopper through the rotating shaft and spiral blades inside the lifting pipe for secondary crushing, thus effectively ensuring the consistency of the crushed residues and the quality of crushing. Through the collection box at the bottom of the discharge box body and the casters at the bottom of the collection box, the rapid collection and transfer of the crushed residues are realized, which is convenient for reducing the labor intensity of operators. When the residues on the filter screen are transported upward for secondary crushing, the residues intercepted by the filter screen are likely to block the small-particle crushed materials, and the residues intercepted by the filter screen and the small-particle crushed materials will be transported upward together, thus increasing the working pressure of the crushing roller. At the same time, the residues on the filter screen are likely to block the inlet of the lifting pipe, and it is not convenient to dredge the inlet of the lifting pipe.

[0004] The patent document with the application number CN202320461899.1 discloses a waste lead-acid battery crushing device. This waste lead-acid battery crushing device can use three groups of crushing components to crush the battery in sequence. During the operation of the crushing components to extrude and crush the waste lead-acid battery, the electrolyte in the waste lead-acid battery seeps out because the shell of the waste lead-acid battery is damaged, and then mostly flows into the electrolyte liquid receiving tray arranged on one side of the bottom of the closed shell through the grid holes on the horizontal support plate. Since the three groups of crushing components are arranged in sequence from top to bottom, when the uppermost crushing component extrudes and crushes the waste lead-acid battery, the electrolyte needs to pass through the two lower crushing components before it can enter the electrolyte liquid receiving tray when seeping out from the battery and passing through the grid holes on the horizontal support plate. The electrolyte is easily discharged after being mixed with the lead paste on the crushed electrode plates, and the collection rate of the electrolyte is low. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is a lead-acid battery recycling and crushing device that can timely collect the electrolyte in the battery after the battery is broken and can improve the electrolyte collection rate.

[0006] In order to achieve the above object, the technical solution provided by the utility model is:

[0007] A lead-acid battery recycling and crushing device includes a housing. Two crushing components are installed in the housing and are arranged vertically up and down. The two crushing components are arranged upside down left and right. A guiding component is arranged at the upper end of the housing. A collecting box is inserted at the lower end of the housing. The lower crushing component is located above the collecting box. An outlet is formed between the collecting box and the housing. The crushing component includes a jaw plate. A crushing roller cooperating with the jaw plate is rotatably arranged in the housing. The crushing roller is driven by a motor fixed on the outer side of the housing. A crushing cavity is formed between the crushing roller and the jaw plate. The crushed material discharged from the crushing cavity of the upper crushing component can enter the crushing cavity of the lower crushing component. A groove is formed in the upper jaw plate. An upper filter screen is fixed inside the upper end of the groove. The groove and the upper filter screen are located below the upper crushing roller. A through groove is formed in the lower jaw plate. A lower filter screen is fixed inside the upper end of the through groove. The lower crushing roller is located above the through groove and the lower filter screen. The groove and the through groove are communicated by a connecting pipe. The connecting pipe is fixed on the housing.

[0008] Specifically, the guiding component includes a guide plate fixed at the upper end of the housing. The guide plate is inclined. The battery falling on the guide plate enters the crushing cavity of the upper crushing component under the guiding action of the guide plate.

[0009] Specifically, a baffle is slidably arranged in the vertical direction inside the housing on one side of the upper jaw plate. The baffle includes a vertical part and an inclined part. The vertical part of the baffle is slidably and sealingly connected with the upper jaw plate. The vertical part of the baffle can block the crushed material in the crushing cavity of the upper crushing component. The lower end of the inclined part of the baffle inclines away from the upper jaw plate. A driving component is arranged inside the housing below the baffle. The driving component is connected with the inclined part of the baffle.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. After the battery is broken in the upper crushing cavity, the electrolyte flowing out of the battery can enter the groove. The electrolyte entering the groove can enter the through groove through the connecting pipe and then flow into the collecting box.

[0012] 2. The vertical part of the baffle can block the crushed material in the upper crushing cavity, which can improve the recovery rate of the electrolyte in the upper crushing cavity. The electrolyte in the lower crushing cavity can flow into the collecting box through the through groove, further improving the collection rate of the electrolyte.

[0013] 3. The height of the baffle can be adjusted. After the baffle descends, the broken materials discharged from the upper crushing cavity can be discharged from the upper jaw plate, and after the battery is broken, the broken materials can be prevented from remaining on the upper jaw plate.

[0032] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0033] Embodiment 1: Referring to Figure 1 - Figure 2 as shown, a lead-acid battery recycling and crushing device includes a housing 1, and two crushing components are installed in the housing 1 and are arranged up and down, and the two crushing components are arranged upside down left and right.

[0034] A guiding component is provided at the upper end of the housing 1. Specifically, the guiding component includes a guide plate 13 fixed to the upper end of the housing 1. The guide plate 13 is inclined, and the lower side of the guide plate 13 is fixedly connected to the housing 1 through a support plate 14. The battery that falls on the guide plate 13 enters the crushing cavity of the upper crushing component under the guiding action of the guide plate 13.

[0035] A collection box 2 is inserted into the lower end of the housing 1. The lower crushing component is located above the collection box 2, and an outlet 15 is formed between the collection box 2 and the housing 1. The crushed material can be discharged to the outside of the housing 1 through the outlet 15.

[0036] The crushing component includes a jaw plate 5. A crushing roller 4 that cooperates with the jaw plate 5 is rotatably provided in the housing 1. The crushing roller 4 is driven by a motor fixed to the outside of the housing 1. A crushing cavity is formed between the crushing roller 4 and the jaw plate 5. The crushed material discharged from the crushing cavity of the upper crushing component can enter the crushing cavity of the lower crushing component.

[0037] A groove 6 is formed in the upper jaw plate 5. An upper filter screen 7 is fixed inside the upper end of the groove 6. The groove 6 and the upper filter screen 7 are located below the upper crushing roller 4.

[0038] A through groove 11 is formed in the lower jaw plate 5. A lower filter screen 12 is fixed inside the upper end of the through groove 11. The lower crushing roller 4 is located above the through groove 11 and the lower filter screen 12.

[0039] The groove 6 is communicated with the through groove 11 through a connecting pipe 3. The connecting pipe 3 is fixed to the housing 1. Specifically, the connecting pipe 3 is in an inverted U shape. The straight part above the connecting pipe 3 is communicated with the groove 6, the straight part below the connecting pipe 3 is communicated with the through groove 11, and the vertical part of the connecting pipe 3 is located outside the housing 1.

[0040] The battery that falls on the guide plate 13 enters the crushing cavity of the upper crushing component under the guiding action of the guide plate 13. The crushing roller 4 of the upper crushing component performs preliminary crushing on the battery. During the process of the battery being crushed in the upper crushing cavity, the electrolyte in the battery can flow into the groove 6 through the upper filter screen 7. The electrolyte in the groove 6 can flow into the through groove 11 through the connecting pipe 3 and then enter the collection box 2.

[0041] The crushed material discharged from the upper jaw plate 5 enters the crushing cavity of the lower crushing component and is subjected to secondary crushing by the crushing roller 4 of the lower crushing component. The electrolyte in the lower crushing cavity can flow into the through hole through the lower filter screen 12 and then enter the collection box 2.

[0042] The crushed material discharged from the lower crushing cavity can be discharged to the outside of the housing 1 through the outlet 15.

[0043] The electrolyte in the upper crushing chamber and the electrolyte in the lower crushing chamber can be collected separately, so it is possible to avoid excessive electrolyte from mixing with the crushed lead paste and then being discharged from the shell 1, and the recovery rate of the electrolyte can be improved.

[0044] Embodiment 2: Based on Embodiment 1, refer to Figure 2 As shown, a baffle 8 is slidably arranged in the vertical direction in the shell 1 on one side of the upper jaw 5, and the baffle 8 includes a vertical portion and an inclined portion. The vertical portion of the baffle 8 is slidably and sealedly connected to the upper jaw 5, and the vertical portion of the baffle 8 can block the crushing objects in the crushing chamber of the upper crushing assembly. The lower end of the inclined portion of the baffle 8 is inclined toward the side away from the upper jaw 5, and a driving assembly is arranged in the shell 1 below the baffle 8, and the driving assembly is connected to the inclined portion of the baffle 8.

[0045] The driving assembly includes a fixing plate 9 fixed in the housing 1 , and a plurality of vertical telescopic rods 10 are fixed on the fixing plate 9 . The upper ends of the telescopic rods 10 are fixedly connected to the inclined portions of the baffle 8 .

[0046] In this embodiment, batteries are intermittently put into the housing 1. By setting the baffle 8, the vertical part of the baffle 8 can block the crushed objects in the upper crushing chamber, so that the electrolyte in the upper crushing chamber has enough time to flow into the groove 6, thereby improving the recovery rate of the electrolyte. After the baffle 8 moves downward, it loses its blocking effect on the crushed objects in the upper crushing chamber, and the crushed objects in the upper crushing chamber can enter the lower crushing chamber. Under the guidance of the inclined part of the baffle 8, the crushed objects discharged from the upper crushing chamber can accurately enter the lower crushing chamber.

[0047] When the crushed objects in the upper crushing chamber enter the lower crushing chamber, the baffle plate 8 moves upward, and the baffle plate 8 can continue to block the crushed objects in the upper crushing chamber after moving upward.

[0048] The height of the baffle 8 can be adjusted so that the vertical portion of the baffle 8 only blocks the crushed objects in the lower layer in the upper crushing chamber, and batteries can be continuously put into the housing 1. After the battery is crushed in the upper crushing chamber, the electrolyte in the battery will penetrate into the crushed objects in the lower layer in the upper crushing chamber. Since the vertical portion of the baffle 8 only blocks the crushed objects in the lower layer in the upper crushing chamber, the electrolyte will enter the groove 6 through the upper filter screen 7. As the amount of crushed objects in the upper crushing chamber continues to increase, under the rotation of the upper crushing roller 4, the upper layer of crushed objects in the upper crushing chamber can pass over the upper end of the vertical portion of the baffle 8 and fall into the crushing chamber below.

[0049] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
