Description

Technical Field

[0001] This utility model relates to the field of waste lead-acid battery recycling and processing technology, and in particular to a lead paste collection device and spray circulation system for waste lead-acid batteries. Background Technology

[0002] Lead paste is the most important component of lead-acid batteries, accounting for approximately 50% of the battery's total weight. Therefore, the recovery rate of lead paste directly impacts the economic benefits of manufacturing companies. In the lead-acid battery recycling process, lead paste collection is achieved through a spray system after disassembly and crushing. High-pressure liquid washes the lead paste off the material, which is then collected and dried through a lead paste collection system. In this process, the cleanliness of the spray water in the spray system directly affects the cleaning effect on the lumpy material. Traditional water purification and circulation systems use two-stage water tanks with bidirectional spirals at the bottom to collect suspended solids in the spray water. This system collects sediment in the middle of the tank, and then uses a vertical pump to extract the sediment and transport it to a collection tank. In this way, the spray water is purified, becoming clear and clean, and can be reused in the spray system.

[0003] However, this cyclic system has some problems in practical applications:

[0004] First, because the sediment in the circulating water is a dilute material with a certain concentration, the spiral collection efficiency is low. When the circulating spray water volume is large, the amount of sediment increases dramatically, causing the water to become turbid. This directly affects the cleaning effect, making it difficult to effectively remove the lead paste.

[0005] Secondly, during this process, a vertical pump is needed to extract the viscous material after sedimentation from the bottom of the tank. When the amount of sediment is large, the pump's delivery capacity is often insufficient, which will also cause the liquid in the spray system to become turbid, failing to achieve the desired effect of cleaning the lead paste.

[0006] These factors can severely impact the normal operation of the dismantling system. Practice shows that after about half a month of continuous operation, the sediment in the circulating water tank will fill up, forcing the entire system to shut down. This not only reduces production efficiency but also increases equipment maintenance and cleaning costs.

[0007] Furthermore, existing lead paste collection devices are often complex in structure, difficult to clean and maintain, and have low collection efficiency. This further exacerbates the technical challenges in the lead-acid battery recycling process.

[0008] To address the aforementioned issues, existing technologies urgently need improvement. Summary of the Invention

[0009] To address the aforementioned problems, the present invention aims to provide a lead paste collection device and spray circulation system for waste lead-acid batteries, which has the advantages of improving lead paste collection efficiency, reducing system downtime, and lowering equipment maintenance costs.

[0010] To achieve the above objectives, the present invention adopts the following technical solution:

[0011] This application provides a lead paste collection device for waste lead-acid batteries, the technical solution of which is as follows: It includes a frame, the inside of which forms a chamber for storing spraying liquid, and a discharge port is constructed at the upper end of the frame; a conveying device is provided inside the frame for conveying the flocculent material settled at the bottom of the chamber to the discharge port; the conveying device includes a conveyor chain circulating inside the frame, a drive assembly for driving the conveyor chain, and multiple scraper assemblies disposed on the conveyor chain; the conveying path of the conveyor chain passes through the bottom of the chamber of the frame, and the scraper assemblies convey the flocculent material to the discharge port as the conveyor chain circulates.

[0012] Furthermore, this application also proposes that a drive wheel and a driven wheel are rotatably arranged inside the frame, and the conveyor chain is positioned inside the frame through the drive wheel and the driven wheel; the output end of the drive assembly is connected to the drive wheel.

[0013] Furthermore, this application also proposes that a tensioning device is provided on the frame, and the drive assembly and drive wheel are mounted on the tensioning device.

[0015] Furthermore, this application also proposes that at least two conveyor chains be provided inside the frame, and the two ends of the scraper assembly are respectively connected to the two conveyor chains.

[0017] Furthermore, this application also proposes that multiple hoppers are provided on the outer side of the frame at the discharge port, and the multiple hoppers are arranged along the length direction of the scraper assembly at the discharge port.

[0018] Furthermore, this application also proposes that the chamber bottom plate of the frame is obtuse-angled, and the discharge port is constructed on the upper end of the chamber bottom plate; the conveying path of the conveyor chain is in contact with the surface of the chamber bottom plate of the frame.

[0019] Furthermore, this application also proposes that a track support is provided above the chamber bottom plate of the frame, and the conveyor chain is arranged cyclically around the track support; an arc-shaped pressure plate is provided at the upper end of the obtuse angle of the track support to press the conveyor chain so that it fits against the track support.

[0020] Furthermore, this application also proposes a spray circulation system, including the lead paste collection device for the aforementioned waste lead-acid batteries.

[0021] As described above, the lead paste collection equipment and spraying circulation system for waste lead-acid batteries provided in this application include a frame, with a chamber for storing spraying liquid formed inside the frame, and a discharge port constructed at the upper end of the frame. A conveying device is installed inside the frame to transport the flocculent material precipitated at the bottom of the chamber to the discharge port.

This provides advantages such as improved lead paste collection efficiency, reduced system downtime, and lower equipment maintenance costs. Attached Figure Description

Example 1

[0031] like Figures 1-4As shown, this embodiment proposes a lead paste collection device for waste lead-acid batteries, including a frame 1. The frame 1 has a chamber 10 inside for storing spraying liquid, and a discharge port 12 is constructed at the upper end of the frame 1. A cover plate 11 is provided above the frame 1 to seal the chamber 10. A conveying device is provided inside the frame 1 to transport the flocculent material a settled at the bottom of the chamber 10 to the discharge port 12. The conveying device includes a conveyor chain 21 circulating inside the frame 1, a drive assembly 22 for driving the conveyor chain 21, and multiple scraper assemblies 3 mounted on the conveyor chain 21. The conveying path of the conveyor chain 21 passes through the bottom of the chamber 10 of the frame 1, and the scraper assemblies 3 transport the flocculent material a to the discharge port 12 as the conveyor chain 21 circulates. This technical solution, through the combination of the frame 1, the conveying device, the conveyor chain 21, the drive assembly 22, and the scraper assemblies 3, solves the problem of low conveying efficiency of flocculent material a during the collection of lead paste from waste lead-acid batteries. The chamber 10 formed inside the frame 1 is used to store the spray liquid, and the outlet 12 at the upper end of the frame 1 is used to output flocculent a. The conveying device effectively transports the flocculent a from the bottom of the chamber 10 to the outlet 12 through the cyclic operation of the conveyor chain 21 and the scraper assembly 3. The drive assembly 22 ensures the continuous operation of the conveyor chain 21, while the scraper assembly 3 is responsible for scraping the flocculent a from the bottom of the chamber 10 and transporting it to the outlet 12. Compared with the spiral collection scheme described in the prior art, this design causes less disturbance to the water body, which is conducive to flocculent sedimentation and thus improves the cleanliness of the spray liquid. Moreover, the sedimentation of flocculent a increases the conveying efficiency of flocculent a, ensuring the continuity and efficiency of the lead paste collection process. Compared with the prior art, this technical solution has the following advantages: First, the design of the conveyor chain 21 and the scraper assembly 3 makes the conveying of flocculent a more efficient, avoiding the water turbidity problem caused by excessive sediment in the traditional spiral collection scheme. Secondly, the cyclical operation of the conveyor chain 21 ensures the continuous transport of flocculent a, avoiding production interruptions due to untimely transport. Finally, the design of the scraper assembly 3 enables the flocculent a to be effectively scraped and transported to the discharge port 12, improving the efficiency of lead paste collection.

[0032] In the specific design, a drive wheel 23 and a driven wheel 24 are rotatably mounted inside the frame 1, and the conveyor chain 21 is positioned inside the frame 1 via the drive wheel 23 and driven wheel 24. The output end of the drive assembly 22 is connected to the drive wheel 23. The arrangement of the drive wheel 23 and driven wheel 24 ensures the circulation path of the conveyor chain 21 within the frame 1, and the drive assembly 22 provides power for the operation of the conveyor chain 21 by connecting to the drive wheel 23. This technical solution effectively solves the technical problem of positioning and running the conveyor chain 21 inside the frame 1, ensuring the efficient operation of the lead paste collection device. Specifically, the drive wheel 23 and driven wheel 24 can be configured in various ways. For example, the drive wheel 23 and driven wheel 24 can be driven by gears, transmitting power through gear meshing. Alternatively, they can be driven by belts, transmitting power through belt friction. Furthermore, the drive wheel 23 and driven wheel 24 can be made of wear-resistant alloy steel to improve their service life. The drive assembly 22 can be driven by a motor, which rotates the drive wheel 23, thereby driving the conveyor chain 21. Thus, the technical solution of this application, by setting the drive wheel 23 and the driven wheel 24, enables the conveyor chain 21 to be precisely positioned and stably run within the frame 1. The arrangement of the drive wheel 23 and the driven wheel 24 ensures the circulation path of the conveyor chain 21 within the frame 1, and the drive assembly 22, by connecting to the drive wheel 23, provides power for the operation of the conveyor chain 21. This technical solution effectively solves the technical problem of positioning and running the conveyor chain 21 within the frame 1, ensuring the efficient operation of the lead paste collection device. Compared with the prior art, the technical solution of this application has higher positioning accuracy and operational stability, and can significantly improve the working efficiency of the lead paste collection device.

[0033] Furthermore, a tensioning device 25 is provided on the frame 1, and the drive assembly 22 and drive wheel 23 are mounted on the tensioning device 25. The tensioning device 25 includes a slide rail 251 mounted on the frame 1, an adjusting base 252 slidably mounted on the frame 1, and an adjusting rod 253 for fixing the adjusting base 252 to the frame 1. The drive assembly 22 and drive wheel 23 are mounted on the adjusting base 252. Specifically, the tensioning device 25, through the sliding arrangement of the slide rail 251 and the adjusting base 252, allows the positions of the drive assembly 22 and drive wheel 23 to be adjusted as needed, thereby ensuring the tension of the conveyor chain 21. The adjusting rod 253 is used to fix the position of the adjusting base 252, ensuring that the positions of the drive assembly 22 and drive wheel 23 remain stable after adjustment. This design effectively avoids the problem of the conveyor chain 21 becoming loose or unstable due to insufficient tension, thereby improving the operating efficiency and reliability of the equipment. In a preferred embodiment, the slide rail 251 can be a linear guide or a curved guide to adapt to different frame 1 structures and conveyor chain 21 paths. The adjusting base 252 can be adjusted manually or automatically, with the automatic adjustment including an electric or pneumatic drive device to improve the accuracy and efficiency of the adjustment. The adjusting rod 253 can be in various forms such as a threaded rod, hydraulic rod, or pneumatic rod to ensure that the adjusting base 252 is firmly fixed in the adjusted position. Thus, the technical solution of this application, through the setting of the tensioning device 25, realizes the flexible adjustment and fixation of the position of the drive assembly 22 and the drive wheel 23, effectively solving the technical problem of loosening or unstable operation of the conveyor chain 21 due to insufficient tension during operation. Compared with the prior art, the technical solution of this application has higher adjustment accuracy and stability, and can significantly improve the operating efficiency and reliability of the equipment.

[0034] Furthermore, at least two conveyor chains 21 are installed inside the frame 1, with both ends of the scraper assembly 3 connected to the two conveyor chains 21 respectively. This design, through the structure of the double conveyor chains 21, significantly improves the stability and operating efficiency of the scraper assembly 3 during the conveying process. Specifically, the design of the double conveyor chains 21 can be implemented in various ways. For example, the conveyor chains 21 can be chains, belts, or other flexible transmission devices, and the scraper assembly 3 can be fixed to the conveyor chains 21 by bolts, welding, or other connection methods. In addition, the conveyor chains 21 can be arranged in parallel or staggered according to the internal space of the frame 1 to optimize the movement trajectory of the scraper assembly 3. The shape and size of the scraper assembly 3 can also be adjusted according to actual needs to better adapt to the collection and conveying requirements of lead paste. Through this design, the scraper assembly 3 is more stable during operation, reducing equipment failures and inefficiencies caused by the instability of a single conveyor chain 21. The structure of the double conveyor chains 21 not only improves the load-bearing capacity of the equipment but also makes the collection of lead paste more efficient and reliable. Compared with existing technologies, this design can effectively solve the stability and efficiency problems of the conveyor chain 21 and scraper assembly 3 in the waste lead-acid battery lead paste collection device, thereby improving the overall performance and operation of the equipment.

[0035] Furthermore, the scraper 31 in the scraper assembly 3 is constructed with an "L"-shaped groove. This "L"-shaped groove design allows the scraper 31 to more effectively scrape and transport flocculent a during circulation, ensuring that flocculent a can be smoothly transported to the discharge port 12, thereby solving the problems of slippage and low efficiency that may occur during the conveying process. The "L"-shaped groove design of the scraper 31 can be achieved in various ways. For example, the "L"-shaped groove of the scraper 31 can be achieved by cutting a right-angle groove on one side of the scraper 31, or by bending one end of the scraper 31 into a right-angle shape to form the groove. In addition, the "L"-shaped groove of the scraper 31 can also be formed by welding or other connection methods to combine two independent scraper 31 components. These implementation methods can all ensure that the scraper 31 can effectively scrape and transport flocculent a when running on the conveyor chain 21. Thus, the technical solution of this application, through the "L"-shaped groove scraper 31 design, significantly improves the stability and efficiency of the scraper 31 assembly 3 on the conveyor chain 21. Compared with existing technologies, this design not only effectively prevents flocculent a from slipping during transportation, but also improves transportation efficiency, ensuring that flocculent a can be smoothly transported to the discharge port 12. This improvement has significant advantages in practical applications, especially when processing large quantities of flocculent a, as it can significantly reduce downtime and maintenance costs, thereby improving the overall system operating efficiency.

[0036] Furthermore, multiple hoppers 4 are provided on the discharge port 12, arranged along the length of the scraper assembly 3. This design can be implemented by adjusting the number of hoppers 4 according to the length of the discharge port 12 and the distribution requirements of the lead paste, ensuring that the lead paste is evenly distributed in each hopper 4. The hoppers 4 can be rectangular or trapezoidal in shape to facilitate the smooth flow and collection of the lead paste. The spacing between the hoppers 4 can be optimized according to the operating speed of the scraper assembly 3 and the flowability of the lead paste, ensuring that the lead paste is evenly dispersed in each hopper 4 during discharge. Therefore, the technical solution of this application, by providing multiple hoppers 4 on the discharge port 12 and arranging them along the length of the scraper assembly 3, enables the lead paste to be evenly distributed in each hopper 4 during discharge. This design solves the problem of uneven lead paste distribution at the discharge port 12 in traditional lead paste collection devices, improving the efficiency and uniformity of lead paste collection. The arrangement of multiple hoppers 4 allows the lead paste to be dispersed into different hoppers 4 during discharge, preventing it from concentrating in one area and thus improving the collection efficiency. Compared with existing technologies, the technical solution of this application has higher lead paste collection efficiency and better uniformity, effectively improving the lead paste recovery rate, reducing downtime during production, and increasing production efficiency.

[0037] like Figure 2 As shown, the bottom plate of the chamber 10 of the frame 1 is obtuse-angled, and the discharge port 12 is constructed on the upper end of the bottom plate of the chamber 10. The conveying path of the conveyor chain 21 conforms to the surface of the bottom plate of the chamber 10 of the frame 1. A track support 5 is provided above the bottom plate of the chamber 10 of the frame 1, and the conveyor chain 21 is arranged in a loop around the track support 5. An arc-shaped pressure plate 6 is provided at the upper end of the obtuse-angled end of the track support 5 to press the conveyor chain 21 into contact with the track support 5. The obtuse-angled bottom plate design of the chamber 10 allows the conveyor chain 21 to better conform to the bottom plate surface during operation, reducing the gap between the conveyor chain 21 and the bottom plate, thereby improving the conveying efficiency. The discharge port 12 is located at the upper end of the bottom plate of the chamber 10, facilitating the smooth discharge of flocculent a. The track support 5 further ensures the stable operation of the conveyor chain 21, preventing it from loosening or shifting during operation. The arc-shaped pressure plate 6 applies pressure to ensure a tight fit between the conveyor chain 21 and the track support 5, further improving the stability of the conveying process. Therefore, this application effectively solves the technical problem of low conveying efficiency caused by the poor fit between the conveyor chain 21 and the bottom plate of the chamber 10 in waste lead-acid battery paste collection equipment. Compared with existing technologies, this application, through the combined design of the obtuse-angled bottom plate of the chamber 10, the track support 5, and the arc-shaped pressure plate 6, significantly improves the fit between the conveyor chain 21 and the bottom plate, ensuring the stability and efficiency of the conveying process, thereby improving the overall performance of the lead paste collection equipment.

[0038] Specifically, the track support 5 can be made of metal, and its shape and size can be customized according to the running path of the conveyor chain 21 and the structure of the bottom plate of the chamber 10. The arc-shaped pressure plate 6 can be installed on the upper end of the obtuse angle of the track support 5 by bolts or other fixing methods to ensure that it can effectively press down on the conveyor chain 21. In addition, the curvature of the arc-shaped pressure plate 6 can be adjusted according to the thickness and running speed of the conveyor chain 21 to achieve the best fit. As a preferred embodiment, the arc-shaped pressure plate 6 can also be made of wear-resistant material to reduce wear during long-term operation. Thus, the technical solution of this application, through the cooperation of the track support 5 and the arc-shaped pressure plate 6, effectively solves the stability problem that may occur in the conveyor chain 21 during operation, ensuring the continuous and efficient operation of the equipment. Compared with the prior art, the technical solution of this application has higher stability and longer service life, and can significantly improve the working efficiency and reliability of the lead paste collection equipment.

The technical solution of this application solves the problem of insufficient cleanliness of the spray water in the spray circulation system by introducing a lead paste collection device. The lead paste collection device, through its internal conveyor chain 21, scraper assembly 3, and other structures, can effectively transport the flocculants a in the spray liquid to the discharge port 12, thereby maintaining the cleanliness of the spray liquid. This design ensures that the spray system can continuously provide clean spray water during high-pressure liquid cleaning, improving the cleaning effect of the lead paste. Furthermore, the structural design of the lead paste collection device also ensures continuous operation of the system, avoiding system downtime caused by sediment accumulation. Compared with the prior art, the technical solution of this application has significant advantages in improving the cleanliness of the spray water and the continuity of system operation.
