[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] like Figures 1 to 8As shown, a lead waste collection system for lead-acid battery production includes a lead slag drying mechanism, a lead slag screening mechanism and a control terminal. The lead slag drying mechanism includes a drying tank 1 and a fan. The drying tank 1 is provided with a first cavity 2 and a second cavity 3. The drying tank 1 is provided with an exhaust port 4, a feed port 5 and a discharge port 6 connected to the first cavity 2, and an air inlet 7 connected to the second cavity 3 on the outside. The second cavity 3 is provided with a ventilation hole 8 connected to the first cavity 2. A filter screen 9 is fixedly arranged in the ventilation hole 8. The output end of the fan is connected to the air inlet 7. A stirring component for stirring the lead slag is provided in ... The lead slag screening mechanism includes a screening box 10, a sliding frame 11, a screening frame 12 and a collecting frame 13. The top of the screening box 10 is communicated with the discharge port 6. A plurality of longitudinally arranged chutes 14 are arranged in the screening box 10. The sliding frame 11 and the screening frame 12 are both provided with a plurality of chutes, and each sliding frame 11 is slidably connected to the corresponding chutes 14. Each screening frame 12 is fixedly connected to the corresponding sliding frame 11. The collecting frame 13 is slidably connected to the bottom of the screening box 10. A driving component for driving the sliding frame 11 to slide in the chutes 14 is provided on the outside of the screening box 10. The stirring component, the heating component and the driving component are all electrically connected to the control terminal.

[0033] When the lead slag containing high moisture or humidity enters the first cavity 2 of the drying tank 1 through the feed port 5, the fan and the heating component are started through the control terminal. The fan inhales the external air and heats it through the heating component to form hot air, and then the hot air enters the second cavity 3 of the drying tank 1 through the air inlet 7. The hot air enters the first cavity 2 through the ventilation hole 8 and the filter screen 9, fully contacts with the lead slag, and uses the high temperature of the hot air to evaporate the moisture in the lead slag. The filter screen 9 can isolate the lead slag to prevent the lead slag from entering the second cavity 3 through the ventilation hole 8. At the same time, the stirring component starts to work, continuously stirring the lead slag to ensure that the lead slag particles are evenly heated, effectively preventing the particles from sticking together due to excessive moisture, and improving the drying efficiency of the lead slag. The dried lead slag enters the screening box 10 through the discharge port 6.

[0034] The dried lead slag enters the screening box 10, which is provided with a plurality of longitudinally arranged chutes 14 and a sliding frame 11 and a screening frame 12 slidably connected thereto. The driving component is started by the control terminal to drive the sliding frame 11 to slide along the chutes 14, thereby driving the lead slag in the screening frame 12 to be screened. It should be specifically explained that the screening aperture of the screening frame 12 becomes smaller from top to bottom, and lead slag particles of different particle sizes will be retained in different screening frames 12, and lead slag particles with a particle size smaller than the screening aperture will finally fall into the collection frame 13 below, thereby realizing the graded collection of lead slag particles of different particle sizes.

[0035] The collecting frame 13 is slidably connected to the bottom of the screening box 10, so that it is easy to take out and replace after the collection is completed, thereby ensuring continuous operation.

[0036] The lead slag drying mechanism effectively removes moisture and humidity from the lead slag, significantly reduces the bonding between particles, avoids clogging of the sieve holes, allows fine-grained materials to pass through the sieve smoothly, and improves screening efficiency. Grading screening allows lead slag of different particle sizes to be separated and collected, improving the recovery purity and reuse value of lead waste. In addition, the control terminal realizes automated control of processes such as stirring, heating, and screening, reduces manual operations, and improves production efficiency and safety.

[0037] refer to Figure 3 As shown, in some specific embodiments, the stirring assembly includes a rotating shaft 15 and a first motor 16. The rotating shaft 15 is rotatably arranged in the first cavity 2. The first motor 16 is fixedly connected to the drying tank 1. The output end of the first motor 16 is coaxially fixedly connected to the rotating shaft 15. A spiral blade 17 is fixedly provided on the outer side of the rotating shaft 15. The first motor 16 is electrically connected to the control terminal.

[0038] When the first motor 16 is started, its power is directly transmitted to the rotating shaft 15, driving the rotating shaft 15 to rotate. Spiral blades 17 are fixedly provided on the outer side of the rotating shaft 15, and these blades 17 move with the rotation of the rotating shaft 15. The spiral blades 17 can effectively turn over and stir the lead slag, so that the lead slag particles are constantly rolling and dispersing in the drying tank 1, increasing the contact area and contact time between the lead slag and the hot air, improving the heat conduction efficiency, thereby accelerating the evaporation rate of water and improving the drying efficiency.

[0039] refer to Figure 3 As shown, in some specific embodiments, the stirring assembly further includes a scraper 18 , one side of the scraper 18 is located at the end of the ventilation hole 8 in the first cavity 2 , and the other side of the scraper 18 is fixedly connected to the rotating shaft 15 .

[0040] When the rotating shaft 15 rotates under the drive of the motor, the scraper 18 also rotates. The rotation path of the scraper 18 covers the port area of ​​the ventilation hole 8, so that the lead slag particles or agglomerates attached to the port of the ventilation hole 8 can be scraped off to prevent the lead slag from clogging the ventilation hole 8 and affecting the circulation and drying effect of the hot air.

[0041] refer to Figure 3 As shown, in some specific embodiments, the heating assembly includes an electric heating coil 19, which is fixedly arranged at the air inlet 7. When the airflow generated by the fan enters the drying tank 1 through the air inlet 7, it will first pass through the electric heating coil 19. When the electric heating coil 19 is energized, it will generate heat, which is quickly transferred to the airflow passing through the air inlet 7, causing its temperature to rise and form hot air. The electric heating coil 19 is electrically connected to the control terminal.

[0042] refer to Figure 3As shown, in some specific embodiments, the heating component includes a temperature sensor 20, which is fixedly arranged in the air inlet 7 and located between the electric heating coil 19 and the second cavity 3, and the temperature sensor 20 is electrically connected to the control terminal. The temperature sensor 20 can monitor and capture the temperature data of the hot air in real time, and then convert these data into electrical signals, which are transmitted through an electrical connection with the control terminal. After receiving the electrical signal from the temperature sensor 20, the control terminal will parse and process it to obtain the actual temperature value of the current hot air. According to this temperature value, the control terminal can further adjust the heating power of the electric heating coil 19 to achieve precise control of the hot air temperature.

[0043] refer to Figure 4 As shown, in some specific embodiments, the driving assembly includes a mounting frame 21, a turntable 22, a first turntable 23, a second turntable 24, a connecting rod 25 and a second motor 26. The mounting frame 21 is fixedly connected to the screening box 10, the second motor 26 is fixedly connected to the mounting frame 21, the turntable 22 is coaxially fixedly connected to the output end of the second motor 26, the first turntable 23 is fixedly connected to the sliding frame 11, the second turntable 24 is fixedly connected to the turntable 22, one end of the connecting rod 25 is hinged to the first turntable 23, and the other end of the connecting rod 25 is hinged to the second turntable 24.

[0044] When the second motor 26 is started, the turntable 22 starts to rotate. As the turntable 22 rotates, the second rotating rod 24 also rotates. Since the two ends of the connecting rod 25 are respectively hinged to the first rotating rod 23 and the second rotating rod 24, the connecting rod 25 will swing under the drive of the second rotating rod 24. This swing is transmitted to the first rotating rod 23 through the connecting rod 25, thereby driving the sliding frame 11 to reciprocate in the screening box 10. The reciprocating motion of the sliding frame 11 helps to increase the number and strength of contact between the lead waste and the screening frame 12, thereby improving the screening effect and ensuring that lead waste of different particle sizes is effectively separated.

[0045] refer to Figure 8 As shown, in some specific embodiments, a plurality of adjustment holes 27 equidistantly arranged longitudinally are provided on the top of the turntable 22 , and the second turn rod 24 is fixedly disposed in the adjustment hole 27 .

[0046] Specifically, by fixing the second rotating rod 24 in the adjusting hole 27 at different positions, the sliding stroke of the sliding frame 11 can be adjusted. This adjustability enables the driving assembly to adapt to the requirements of different screening tasks and screening conditions, thereby improving the flexibility and adaptability of the lead slag screening mechanism.

[0047] refer to Figure 5 , Figure 6 and Figure 7As shown, in some specific embodiments, the lead slag screening mechanism also includes a locking rod 28, the sliding frame 11 is provided with a mounting groove 29, the screening frame 12 is fixed with a mounting block 30 that slides with the mounting groove 29, the mounting groove 29 is provided with a positioning hole 31, the mounting block 30 is provided with a locking hole 32, and the locking rod 28 is arranged through the positioning hole 31 and the locking hole 32.

[0048] When the mounting block 30 of the screening frame 12 is inserted into the mounting groove 29 of the sliding frame 11, the positioning hole 31 and the locking hole 32 are aligned, and then the locking rod 28 is inserted into the positioning hole 31 and the locking hole 32, so that the screening frame 12 can be fixedly installed on the sliding frame 11. When the lead slag screening is completed, the locking rod 28 only needs to be pulled out from the positioning hole 31 and the locking hole 32 to realize the removal and separation of the screening frame 12 from the sliding frame 11.

[0049] In some specific embodiments, an external thread is fixedly provided on the outer side of the locking rod 28, and an internal thread matching the external thread is provided on the inner side of the locking hole 32. When the locking rod 28 is rotated and inserted into the locking hole 32, the external thread and the internal thread will engage with each other, thereby increasing the locking force and preventing the screening frame 12 from loosening or falling off during operation.

[0050] refer to Figure 3 As shown, in some specific embodiments, a plurality of ventilation holes 8 are provided and arranged in a ring shape in the first cavity 2. The ventilation holes 8 are arranged in a ring shape to ensure that the air circulation in the first cavity 2 is more uniform. This distribution method avoids the problem of poor ventilation or overheating in a local area, and helps to maintain the temperature balance in the entire cavity. Multiple ventilation holes 8 working at the same time can significantly increase the air circulation, thereby improving the heat dissipation efficiency. This is beneficial for the lead slag drying mechanism to handle a large amount of lead slag with a heavy workload.

[0051] In order to facilitate the understanding of the embodiments of the present invention by those skilled in the art, the working principle of the embodiments of the present invention is now described in combination with specific application scenarios:

[0052] In actual use, the lead slag containing high moisture or humidity is fed into the first cavity 2 of the drying tank 1 through the feed port 5. The fan and the heating component are started through the control terminal. The fan draws in external air and heats it through the heating component to form hot air.

[0053] The hot air enters the second cavity 3 of the drying tank 1 through the air inlet 7, and then enters the first cavity 2 through the ventilation hole 8 and the filter 9. The filter 9 prevents the lead slag from entering the second cavity 3, and the hot air is in full contact with the lead slag to evaporate the moisture in the lead slag.

[0054] At the same time, the stirring assembly starts working, constantly stirring the lead slag to ensure that the lead slag particles are evenly heated to prevent the particles from sticking together. After a period of drying, the moisture in the lead slag is evaporated in large quantities, and the dried lead slag enters the screening box 10 through the discharge port 6.

[0055] The dried lead slag enters the screening box 10, in which a plurality of longitudinally arranged chutes 14 are provided, to which the sliding frame 11 and the screening frame 12 are slidably connected. The screening aperture of the screening frame 12 decreases from top to bottom.

[0056] The driving assembly is started by the control terminal. The second motor 26 drives the turntable 22 to rotate, and then drives the sliding frame 11 to slide back and forth in the sliding groove 14 through the connecting rod 25.

[0057] The reciprocating motion of the sliding frame 11 drives the lead slag in the screening frame 12 to be screened. Lead slag particles of different particle sizes will remain in different screening frames 12, and lead slag particles with particle sizes smaller than the screening aperture will eventually fall into the collection frame 13 below.

[0058] The collecting frame 13 is slidably connected to the bottom of the screening box 10, so that it is convenient to take out and replace the new collecting frame 13 after the collection is completed, thereby ensuring continuous operation.

[0059] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
