Description

Technical Field

[0001] This invention belongs to the technical field of lead sludge recycling devices, specifically relating to a lead-acid battery lead sludge recycling device. Background Technology

[0002] Lead-acid batteries are widely used in automotive starting, electric bicycles, communication base stations, and energy storage systems due to their advantages such as stable voltage and long cycle life. With the continuous expansion of lead-acid battery applications in my country, market demand continues to grow, driving the continuous expansion of lead-acid battery production capacity. At the same time, the number of waste lead-acid batteries generated annually is also increasing significantly. How to efficiently and environmentally recycle these waste batteries has become an important issue for the industry.

[0003] The recycling process of waste lead-acid batteries typically involves crushing, sorting, neutralization, and solid-liquid separation. Specifically, the neutralized lead-acid solution needs to be filtered using a membrane filter press to achieve solid-liquid separation, thereby obtaining lead sludge rich in lead. This lead sludge is a key raw material for subsequent smelting to produce metallic lead. However, in actual production, after filtration, some lead sludge adheres to the surface of the filter membrane and is difficult to remove naturally by gravity.

[0004] A Chinese patent with publication number CN117878464A discloses a lead-acid battery lead sludge recycling device. It can scrape off the lead paste on the surface of the filter membrane by setting a scraping component, and can move the filter membrane by setting a moving component, thereby scraping off the lead paste on both sides of each filter membrane.

[0005] However, in the above solution, after completing one scraping operation, the scraper needs to be retracted upwards via a lifting mechanism. During the retraction process, the scraper moves in the opposite direction along the surface of the filter membrane that has just been cleaned. Since the scraped-off lead sludge is still attached to the scraper, this reverse movement can easily cause some of the lead sludge to re-adhere to the cleaned filter surface, causing secondary pollution and directly affecting the cleaning effect.

[0006] To address the above problems, this invention proposes a lead-acid battery lead sludge recycling device. Summary of the Invention

[0007] To address the problems existing in the background art, the present invention provides a lead-acid battery lead sludge recycling device.

[0008] To achieve the above objectives, the present invention provides the following technical solution: A lead-acid battery lead sludge recycling device includes a machine base. A hydraulic plate is slidably mounted within the machine base, and multiple filter membrane plates are slidably mounted within it via a support assembly. The hydraulic plate is used to compress the multiple filter membrane plates. A connecting frame is fixedly mounted on the top of the machine base. A connecting seat is slidably mounted within the connecting frame, and a driving mechanism acts on the connecting seat. A sliding rod is slidably mounted on the connecting seat, and the sliding directions of the connecting seat and the sliding rod are perpendicular to each other. A scraping component and a pushing component acting on the filter membrane plates are mounted on the sliding rod. A magnetic guide component and a resetting component acting on the sliding rod are mounted at the bottom of the connecting frame.

[0009] Furthermore, the support assembly includes a guide rod, which is fixedly installed inside the machine base. Each filter membrane plate is fixedly provided with a connecting block, which is slidably sleeved on the outer surface of the guide rod.

[0010] Furthermore, the driving mechanism includes a first motor, and the top of the connecting frame is both rotatably provided with a first threaded rod and fixedly provided with a fixing rod; one end of the connecting seat is threaded onto the outer surface of the first threaded rod, and the other end of the connecting seat is slidably provided onto the outer surface of the fixing rod; the first motor is fixedly installed on the top of the connecting frame, and the output shaft of the first motor is coaxially and fixedly connected to one end of the first threaded rod.

[0011] Furthermore, the scraping assembly includes scrapers, and two scrapers are symmetrically arranged on both sides of the sliding rod, with each scraper connected to the sliding rod by a spring. One end of the spring is fixedly connected to the scraper, and the other end of the spring is fixedly connected to the sliding rod.

[0012] Furthermore, the push-opening component includes protrusions, and two protrusions are fixedly provided on the outer surface of the sliding rod. The two protrusions are symmetrically distributed on both sides of the sliding rod where no scraper is provided. Each end of the filter membrane plate is provided with an inclined surface, and the protrusions and the inclined surfaces are in transmission cooperation.

[0013] Furthermore, the magnetic guide assembly includes a guide frame, which is fixedly installed at the bottom of the connecting frame. Multiple second guide grooves are symmetrically formed on the guide frame. A first guide groove is connected between adjacent second guide grooves, and a reset groove is connected between the beginning and end of two second guide grooves. The first guide groove, the second guide groove, and the reset groove form a connected guide path. The sliding rod is slidably positioned within the guide path. A magnet is fixedly embedded at the corner where the first guide groove and the second guide groove connect, and the magnet magnetically engages with the sliding rod.

[0014] Furthermore, the reset assembly includes a second motor, and the bottom of the connecting frame is rotatably provided with a second threaded rod and a push block is slidably provided for limiting. The push block is threaded onto the outer surface of the second threaded rod, and the push block is in transmission cooperation with the sliding rod. The second motor is fixedly installed at the bottom of the connecting frame, and the output shaft of the second motor is coaxially fixedly connected to one end of the second threaded rod.

[0015] Furthermore, the connecting seat is provided with a sliding groove for limiting the sliding of the sliding rod.

[0016] The present invention has the following beneficial effects: 1. During the sliding process of the drive mechanism, which moves the sliding rod and scraping component, the scraping component only performs a unidirectional scraping action. This avoids the possibility of the scraping component bringing lead sludge back to the cleaned surface, thus ensuring the cleanliness of the cleaning. Specifically, after the scraping component moves from one end of the filter membrane plate to the other and completes the scraping, it does not retract along the cleaned filter surface. Instead, with the cooperation of the magnetic guide component and the pusher, it pushes open the cleaned filter membrane plate and moves to the filter surface of the next set of filter membrane plates to be cleaned. Simultaneously, after completing the scraping operation, the scraping component can slide back to its original position under the push of the reset component, allowing for the next scraping and cleaning operation.

[0017] 2. This application includes multiple sets of magnets within the magnetic guide assembly. When the sliding rod carrying the scraping assembly passes the magnets, it is quickly attracted by the magnets, resulting in instantaneous acceleration and impact vibration. This vibration can dislodge the lead sludge adhering to the scraping assembly, achieving self-cleaning of the scraping assembly and thus ensuring the cleaning effect of the scraping assembly on the subsequent filter membrane plate.

[0018] 3. This application achieves a combined motion of stepping, scraping, and vibration of the scraping component between multiple filter membrane plates by simply driving the scraping component to slide, and with the guidance of the magnetic guide component. Simultaneously, the reset process can be completed simply by activating the reset component. The entire process eliminates the need for complex mechanisms relying on variable factors such as friction, springs, and weight blocks for positioning and transmission, thus simplifying the structure, making the motion logic clearer, and improving operational reliability.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0022] like Figures 1-12As shown, the technical solution adopted by the present invention is as follows: A lead-acid battery lead sludge recycling device includes a machine base 1. A hydraulic plate 5 is slidably and limitly disposed within the machine base 1, and multiple filter membrane plates 2 are slidably and limitly disposed via a support assembly. The hydraulic plate 5 is used to compress the multiple filter membrane plates 2. It should be noted that the machine base 1, filter membrane plates 2, and hydraulic plate 5 in this application have all been disclosed in patent publication number CN117878464A and are considered conventional prior art; therefore, they will not be described in detail here.

[0023] Specifically, such as Figure 1 As shown, the support assembly includes a guide rod 4, which is fixedly installed inside the machine base 1. Each filter membrane plate 2 is fixedly provided with a connecting block 3, which is slidably sleeved on the outer surface of the guide rod 4.

[0024] The top of the machine base 1 is fixedly provided with a connecting frame 6. The connecting frame 6 is provided with a connecting seat 11 for limiting sliding and a driving mechanism acting on the connecting seat 11. The connecting seat 11 is provided with a sliding rod 12 for limiting sliding. The connecting seat 11 is provided with a sliding groove 22 for limiting sliding of the sliding rod 12. The sliding directions of the connecting seat 11 and the sliding rod 12 are perpendicular to each other.

[0025] Specifically, such as Figure 6 As shown, the drive mechanism includes a first motor 7. The top of the connecting frame 6 is rotatably equipped with a first threaded rod 8 and fixedly equipped with a fixing rod 10. One end of the connecting seat 11 is threaded onto the outer surface of the first threaded rod 8, and the other end of the connecting seat 11 is slidably sleeved on the outer surface of the fixing rod 10. The first motor 7 is fixedly installed on the top of the connecting frame 6, and the output shaft of the first motor 7 is coaxially and fixedly connected to one end of the first threaded rod 8.

[0026] The sliding rod 12 is equipped with a scraping component and a pushing component that act on the filter membrane plate 2, and the bottom of the connecting frame 6 is equipped with a magnetic guide component and a reset component that act on the sliding rod 12.

[0027] Specifically, such as Figure 12 As shown, the scraping assembly includes a scraper 15. Two scrapers 15 are symmetrically arranged on both sides of the sliding rod 12, and each scraper 15 is connected to the sliding rod 12 with a spring 24. One end of the spring 24 is fixedly connected to the scraper 15, and the other end of the spring 24 is fixedly connected to the sliding rod 12.

[0028] Specifically, such as Figure 2 , Figure 4 , Figure 5 as well as Figure 11As shown, the push-opening component includes a protrusion 14. Two protrusions 14 are fixedly provided on the outer surface of the sliding rod 12. The two protrusions 14 are symmetrically distributed on both sides of the sliding rod 12 where the scraper 15 is not provided. Each filter membrane plate 2 has an inclined surface 13 at its end, and the protrusions 14 and the inclined surface 13 are in a transmission cooperation.

[0029] Specifically, such as Figure 6 , Figure 7 as well as Figure 10 As shown, the magnetic guide assembly includes a guide frame 9, which is fixedly installed at the bottom of the connecting frame 6. Multiple second guide grooves 18 are symmetrically formed on the guide frame 9. A first guide groove 17 is connected between each adjacent second guide groove 18, and a reset groove 23 is connected between the beginning and end of each second guide groove 18. The first guide groove 17, the second guide groove 18, and the reset groove 23 form a connected guide path, and a sliding rod 12 is slidably positioned within this guide path. Furthermore, a magnet 16 is fixedly embedded at the corner where the first guide groove 17 and the second guide groove 18 connect, and the magnet 16 magnetically engages with the sliding rod 12.

[0030] Specifically, such as Figure 7 and Figure 9 As shown, the reset assembly includes a second motor 19. The bottom of the connecting frame 6 is rotatably equipped with a second threaded rod 20 and also has a push block 21 for limiting sliding. The push block 21 is threaded onto the outer surface of the second threaded rod 20 and is in transmission engagement with the sliding rod 12. The second motor 19 is fixedly mounted on the bottom of the connecting frame 6, and the output shaft of the second motor 19 is coaxially and fixedly connected to one end of the second threaded rod 20. When the sliding rod 12 moves into the reset groove 23, the second motor 19 drives the push block 21 to slide, thereby pushing the sliding rod 12 to reset.

[0031] Working principle: During the recycling of lead sludge, the neutralized lead acid solution is filtered through a diaphragm filter press, and the lead sludge adheres to the surface of the filter diaphragm plate 2. When it is necessary to clean the lead sludge adhering to the surface of the filter diaphragm plate 2, the hydraulic plate 5 is first moved a preset distance away from the filter diaphragm plate 2, so that the hydraulic plate 5 releases the squeezing limit on the multiple filter diaphragm plates 2.

[0032] Subsequently, the first motor 7 is started. The output shaft of the first motor 7 drives the first threaded rod 8 to rotate clockwise. The connecting seat 11 slides along the fixed rod 10, and drives the sliding rod 12 to move linearly along the second guide groove 18 towards the first motor 7. During the movement, the scrapers 15 on both sides of the sliding rod 12 contact the right side of the filter membrane plate 2 to be cleaned and the side of the hydraulic plate 5, respectively, thereby scraping away the lead mud attached to the two surfaces as the scrapers 15 move.

[0033] When the sliding rod 12 moves to the corner where the second guide groove 18 connects to the first guide groove 17, the magnet 16 located at the corner attracts the sliding rod 12, causing the sliding rod 12 to move rapidly toward the magnet 16, thereby causing the scraper 15 to generate a momentary impact vibration. This vibration shakes off the lead sludge adhering to the scraper 15, achieving self-cleaning of the scraper 15.

[0034] Subsequently, the output shaft of the first motor 7 reverses, and the sliding rod 12 moves in the opposite direction along another second guide groove 18. At this time, since the first cleaned filter membrane plate 2 has been released from its limit, the protrusion 14 on the sliding rod 12 engages with the inclined surface 13 at the end of the filter membrane plate 2, pushing the filter membrane plate 2 to move a preset distance to the right, so that the filter membrane plate 2 abuts against the hydraulic plate 5. Afterward, the scraper 15 cleans the relative filter surfaces between two adjacent filter membrane plates 2 during its movement.

[0035] After completing one cleaning cycle, the sliding rod 12 moves again to the position between the next set of adjacent filter membrane plates 2 under the attraction of the magnet block 16. As the first motor 7 alternates between forward and reverse rotation, the scraper 15 cleans the filter surfaces of multiple filter membrane plates 2 in sequence.

[0036] After cleaning, the sliding rod 12 is positioned below the leftmost second guide groove 18. Then, the output shaft of the first motor 7 continues to rotate, causing the sliding rod 12 to move to the corner between the leftmost second guide groove 18 and the reset groove 23. At this point, the sliding groove 22 on the connecting seat 11 coincides with the reset groove 23.

[0037] Subsequently, the second motor 19 is started. The output shaft of the second motor 19 drives the second threaded rod 20 to rotate, and the push block 21 pushes the sliding rod 12 to the right, moving it to the corner of the rightmost second guide groove 18 and the reset groove 23. Then, the first motor 7 drives the sliding rod 12 to move upward to complete the reset, while the second motor 19 reverses to reset the push block 21 to its initial position.

[0038] After cleaning, the hydraulic plate 5 pushes the multiple filter membrane plates 2 to press against each other again, and then the filter can be used for subsequent filtration.

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
