Description

Technical Field

[0001] This utility model relates to the technical field of lead paste recycling equipment, specifically to a lead-acid battery plate lead paste recycling equipment. Background Technology

[0002] The recycling process and principle of lead paste from lead-acid battery plates are mainly based on the chemical properties of lead and metallurgical technology. The aim is to efficiently separate and regenerate lead and other valuable components. Lead paste recycling is usually divided into four core stages: pretreatment, desulfurization conversion, smelting reduction, and refining, ultimately yielding recycled lead and by-products.

[0003] In the pretreatment process of lead paste recycling, waste batteries are generally crushed. Then, the plastic, lead paste, and metallic lead are separated by methods such as water droplet sorting, vibrating sieve, magnetic separation, eddy current separation, and airflow separation. The sorted lead paste is usually transferred by belt conveyor. Because some of the crushed lead paste particles are small, a very small amount of lead paste may slip off the conveyor belt during the conveyor transport process due to the blowing of external airflow. Some lead paste will also stick to the conveyor belt and rotate with it, resulting in a small amount of loss and reducing the recycling rate of lead paste. Utility Model Content

[0004] Therefore, the technical problem to be solved by this utility model is to provide a lead-acid battery plate lead paste recycling device that can firmly adsorb the lead paste onto the conveyor belt when moving the lead paste, and prevent the lead paste from adhering to the conveyor belt after moving the lead paste into the unloading hopper, thereby greatly reducing the loss in the lead-acid battery plate lead paste recycling process and improving the recycling rate of lead paste.

[0005] To address the aforementioned problems, this utility model provides a lead-acid battery plate lead paste recycling device, comprising: a shell, inside which a conveyor belt is provided, the conveyor belt being arranged in a mesh pattern, and a driving mechanism is provided inside the conveyor belt for driving the conveyor belt to rotate; Two support plates are symmetrically arranged inside the conveyor belt, and both sides of the plates are fixedly connected to the inner wall of the outer shell. The opposite sides of the plates are in contact with the inner wall of the conveyor belt. The top support plate has several adsorption holes at equal intervals, and the bottom support plate has several connection holes. A roller brush is located on the bottom side of the connecting hole, and the bristles of the roller brush are in contact with the outer wall of the conveyor belt. The two ends of the roller brush rotate through the shell wall of the outer casing. The feeding hopper is fixedly fitted onto the discharge end of the outer shell. Its hopper wall is equipped with a transmission mechanism to drive the roller brush to rotate, and its outer wall is equipped with an air extraction mechanism to extract the gas inside the feeding hopper.

[0006] Preferably, the driving mechanism includes two driving rollers disposed inside the conveyor belt, with their outer peripheral walls in contact with the inner wall of the conveyor belt. The two ends of the driving rollers are rotatably connected to the outer casing. A driver is fixedly mounted on the side wall of the outer casing, and the driving end of the driver is fixedly connected to the corresponding end of the corresponding driving roller.

[0007] Preferably, the outer peripheral walls of the conveyor belt and the drive rollers are both arc-shaped, curving upwards from the center to both sides, and the two ends of the support plate are in contact with the outer peripheral walls of the two drive rollers respectively.

[0008] Preferably, the transmission mechanism includes two storage slots symmetrically opened on the inner wall of the hopper. Each storage slot is equipped with a main gear, and the two main gears are fixedly connected to the two ends of the corresponding drive rollers. Both ends of the roller brush are fixedly equipped with drive gears, and the two drive gears are located in the two storage slots respectively and are meshed with the two main gears through transmission gears. The transmission gears are rotatably connected to the hopper.

[0009] Preferably, the air extraction mechanism includes an air pump, which is fixedly installed on the outer wall of the hopper, and a fixed cylinder is connected to its lower part. The open end of the fixed cylinder is coplanar with the inner wall of the hopper and is fixedly connected to the hopper. The hopper is provided with a filter block, and the end of the filter block away from the fixed cylinder is inclined and extends out of the fixed cylinder.

[0010] Preferably, a guide rod is provided at the axial center of the filter block, and the filter block is slidably connected to the inner wall of the fixed cylinder and the guide rod respectively. The guide rod is fixedly connected to the inner wall of the fixed cylinder, and a spring is wound around the outer periphery of the guide rod, and the two ends of the spring are fixedly connected to the filter block and the inner wall of the fixed cylinder respectively.

[0011] This utility model has the following beneficial effects: When in use, this improved lead-acid battery plate lead paste recycling equipment uses airflow to firmly press the lead paste onto the conveyor belt. This allows the conveyor belt to move the lead paste into the hopper at a faster speed, while preventing external airflow from blowing off any small amount of lead paste. This increases the lead paste transport rate. Furthermore, the conveyor belt is continuously self-cleaned by a roller brush to prevent the conveyor belt from carrying any small amount of lead paste out of the hopper. The airflow also confines the swept-off lead paste within the hopper to prevent it from floating out. This significantly reduces losses during the lead-acid battery plate lead paste recycling process and improves the lead paste recycling rate. Attached Figure Description

[0018] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0019] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, according to an embodiment of the present invention, a lead-acid battery plate lead paste recycling device is provided, comprising: a shell 1, a conveyor belt 2 provided inside the shell, the conveyor belt 2 being a mesh structure, and a drive mechanism 3 provided inside the conveyor belt 2 for driving the conveyor belt 2 to rotate; Two support plates 6 are symmetrically arranged inside the conveyor belt 2, and both sides of them are fixedly connected to the inner wall of the outer shell 1. Their opposite sides are in contact with the inner wall of the conveyor belt 2. Several adsorption holes 7 are evenly spaced on the top support plate 6, and several connection holes 8 are opened on the bottom support plate 6. A roller brush 9 is located on the bottom side of the connecting hole 8, and the bristles of the roller brush 9 are in contact with the outer wall of the conveyor belt 2. The two ends of the roller brush 9 rotate through the shell wall of the outer casing 1. The feeding hopper 10 is fixedly sleeved on the discharge end of the outer shell 1. The hopper wall is equipped with a transmission mechanism 4 for driving the roller brush 9 to rotate. The outer wall is equipped with an air extraction mechanism 5 for extracting the gas in the feeding hopper 10.

[0020] In this embodiment, when using the improved lead-acid battery plate lead paste recycling equipment, please refer to... Figure 1 , Figure 2 and Figure 4The drive mechanism 3 drives the conveyor belt 2 to rotate at a constant speed inside the outer shell 1, and drives the roller brush 9 to rotate through the transmission mechanism 4. The roller brush 9 continuously cleans the conveyor belt 2 through friction between the brush bristles and the outer wall of the conveyor belt 2. At the same time, the air extraction mechanism 5 is activated to continuously extract the gas in the hopper 10. (The bottom opening of the hopper 10 is equipped with an electrically controlled valve to control the opening and closing of the bottom opening of the hopper 10). As the gas in the hopper 10 is lost, the gas from the outside flows into the hopper 10 through the adsorption hole 7 and the connecting hole 8 or through the gap between the top opening of the hopper 10 and the outer shell 1 and the conveyor belt 2 to replenish the gas lost in the hopper 10. The device is then activated. After the device is started, the lead paste falls directly onto the conveyor belt 2 through the existing feeding or discharging equipment. (The mesh-like conveyor belt 2 forms a structure similar to a sieve plate, which prevents the lead paste from entering the adsorption holes 7 with the airflow.) Due to the pressure difference at both ends of the adsorption holes 7, the lead paste is firmly adsorbed onto the conveyor belt 2. As the conveyor belt 2 rotates, it is moved into the hopper 10. When large pieces of lead paste move to the curved position of the conveyor belt 2, they are directly separated from the conveyor belt 2 due to their own gravity and fall into the hopper 10 for storage. When small particles of lead paste move to the position of the connecting hole 8, the gas flowing out of the connecting hole 8 blows the lead paste off the conveyor belt 2. Finally, the rotating roller brush 9 can sweep off the small amount of lead paste attached to the conveyor belt 2 to ensure that no small amount of lead paste is carried out of the hopper 10 by the conveyor belt 2. It should be noted that, since there is always gas flowing into the discharge hopper opening, the lead paste swept off the conveyor belt 2 will not float out of the discharge hopper 10 with the airflow. In summary, when this improved lead-acid battery plate lead paste recycling equipment is in use, the airflow can firmly press the lead paste onto the conveyor belt 2, allowing the conveyor belt 2 to move the lead paste into the hopper 10 at a faster speed while preventing external airflow from blowing off any small amount of lead paste. This increases the lead paste transport rate. Furthermore, the roller brush 9 continuously cleans the conveyor belt 2 to prevent it from carrying any small amount of lead paste out of the hopper 10. The airflow also confines the swept-off lead paste within the hopper 10, preventing it from floating out. This significantly reduces losses during the lead-acid battery plate lead paste recycling process and improves the lead paste recycling rate.

[0021] In a further preferred embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the drive mechanism 3 includes two drive rollers 31, which are disposed inside the conveyor belt 2, and their outer peripheral walls are in contact with the inner wall of the conveyor belt 2. The two ends of the drive rollers 31 are rotatably connected to the outer casing 1. A driver 32 is fixedly installed on the side wall of the outer casing 1, and the drive end of the driver 32 is fixedly connected to the corresponding end of the corresponding drive roller 31. In this embodiment, please refer to Figure 1 and Figure 2 As shown, when using the device, the driver 32 is started (the driver 32 consists of the housing 1, a servo motor, and a gear transmission structure or a belt pulley transmission structure), which drives the first drive roller 31 to rotate. Due to the friction between the two drive rollers 31 and the inner wall of the conveyor belt 2 and the support and limiting of the two support plates 6 on the conveyor belt 2, the conveyor belt 2 rotates in the housing 1 along a fixed trajectory. The second drive roller 3 also rotates together. At this time, due to the power transmission of the transmission mechanism 4, the rotating second drive roller 31 drives the roller brush 9 to rotate rapidly through the transmission mechanism 4 to clean the lead paste adhering to the conveyor belt 2.

[0022] In a further preferred embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the outer peripheral walls of the conveyor belt 2 and the drive roller 31 are both arc-shaped surfaces that curve upwards from the middle to both sides, and the two ends of the support plate 6 are in contact with the outer peripheral walls of the two drive rollers 31 respectively. In this embodiment, please refer to Figure 1 and Figure 2 As shown, the arc-shaped surface on the outer periphery of the conveyor belt 2 allows more lead paste to be placed on the conveyor belt 2, and makes it more difficult for the lead paste to slide off the conveyor belt 2. The contact arrangement between the two ends of the support plate 6 and the outer peripheral wall of the drive roller 31 makes the two support plates 6 and the two drive rollers 31 form a support structure similar to a waist-shaped hole within the conveyor belt 2, so as to ensure that the conveyor belt 2 slides along a fixed trajectory.

[0023] In a further preferred embodiment of this utility model, such as Figure 2 and Figure 4 As shown, the transmission mechanism 4 includes two storage tanks 41, which are symmetrically opened on the inner wall of the hopper 10. The storage tanks 41 are provided with main gears 42, and the two main gears 42 are fixedly connected to the two ends of the corresponding drive rollers 31. The two ends of the roller brush 9 are fixedly equipped with drive gears 43, and the two drive gears 43 are respectively located in the two storage tanks 41 and are respectively meshed with the two main gears 42 through transmission gears 44. The transmission gears 44 are rotatably connected to the hopper 10. In this embodiment, please refer to Figure 2 and Figure 4 As shown, during the rotation of the second drive roller 31, the main gear 42 is driven to rotate synchronously, thereby driving the roller brush 9 to rotate rapidly in the same direction through the transmission gear 44 and the drive gear 43 (the diameters of the main gear 42 and the transmission gear 44 are much larger than the diameter of the drive gear 43). During the rotation of the roller brush 9, the bristles of the roller brush 9 rub against the outer wall of the conveyor belt 2, thereby sweeping off the lead paste attached to the conveyor belt 2.

[0024] In a further preferred embodiment of this utility model, such as Figure 1 , Figure 2 and Figure 5 As shown, the air extraction mechanism 5 includes an air pump 51, which is fixedly installed on the outer wall of the hopper 10. A fixed cylinder 52 is installed below it, and the open end of the fixed cylinder 52 is coplanar with the inner wall of the hopper 10 and fixedly connected to the hopper 10. A filter block 53 is provided inside the hopper 10, and the end of the filter block 53 away from the fixed cylinder 52 is inclined and extends to the outside of the fixed cylinder 52. In this embodiment, please refer to Figure 1 , Figure 2 and Figure 5 As shown, during the process of the driver 32 driving the conveyor belt 2 to rotate, the air pump 51 is started synchronously to continuously extract the gas in the fixed cylinder 52, so that a pressure difference is formed on both sides of the filter block 53, thereby causing the gas in the feed hopper 10 to flow into the fixed cylinder 52 through the filter hole, so as to continuously extract the gas in the feed hopper 10. When the large piece of lead paste moves to the position of the drive roller 31, the drive roller 31 can block one end opening of the mesh hole of the conveyor belt 2 at the position of the large piece of lead paste. As the conveyor belt 2 bends and deforms, the large piece of lead paste cannot adhere to the inner wall of the corresponding mesh hole, thereby releasing the blockage of the other end opening of the corresponding mesh hole. The adsorption force on the large piece of lead paste is reduced accordingly, making it easier for the large piece of lead paste to separate from the conveyor belt 2. After the large piece of lead paste separates from the conveyor belt 2, it falls and, together with the airflow flowing into the fixed cylinder 52, blows the large piece of lead paste. The lead paste collides with the inclined surface of the filter block 53, causing the filter block 53 to vibrate strongly, so as to shake off the lead paste attached to the inclined surface of the aluminum block. It should be noted that the entire device is automatically controlled by an external control host.

[0025] In a further preferred embodiment of this utility model, such as Figure 2 and Figure 5 As shown, a guide rod 54 is inserted through the axial position of the filter block 53, and the filter block 53 is slidably connected to the inner wall of the fixed cylinder 52 and the guide rod 54 respectively. The guide rod 54 is fixedly connected to the inner wall of the fixed cylinder 52. A spring 55 is wound around the outer periphery of the guide rod 54, and the two ends of the spring 55 are fixedly connected to the filter block 53 and the inner wall of the fixed cylinder 52 respectively. In this embodiment, please refer to Figure 2 and Figure 5As shown, as the airflow continues to flow through the holes of the filter block 53 into the fixed cylinder 52, some lead paste will be adsorbed on the inclined surface of the filter block 53. As the amount of lead paste adhering to the filter block 53 increases, the thrust exerted on the filter block 53 by the airflow through the holes of the filter block 53 also increases, causing the filter block 53 to gradually retract into the fixed cylinder 52. Due to the reduction in the amount of gas passing through the holes of the filter block 53, the negative pressure intensity inside the fixed cylinder 52 also increases. (A pressure sensor is fixedly installed at the bottom of the fixed cylinder 52 to detect the negative pressure intensity inside the fixed cylinder 52). After the negative pressure intensity inside the fixed cylinder 52 reaches the threshold, the air pump 51 stops running and then restarts. When the air pump 51 stops, the spring 55 quickly pushes the filter block 53 to reset, causing the filter block 53 to collide with the guide rod 54 with a strong force, so that the filter block 53 generates a strong vibration, thereby shaking off the lead paste adhering to the inclined surface of the filter block 53.

[0026] Working principle: When this improved lead-acid battery plate lead paste recycling equipment is in use, the lead paste is quickly moved into the hopper 10 by the rotating conveyor belt 2. During this process, the airflow continuously flowing into the outer shell 1 from the outside can exert a restraining force on the lead paste, so that the lead paste will not slip off the conveyor belt 2 due to the blowing of the outside airflow as it moves quickly with the conveyor belt 2. After the lead paste is brought into the feeding port by the conveyor belt 2, the lead paste itself, together with the cleaning of the conveyor belt 2 by the roller brush 9, falls from the conveyor belt 2 into the feeding hopper 10 for storage. The lead paste in the feeding hopper 10 can be discharged by opening the electric control valve at the bottom opening of the feeding hopper 10 at regular intervals.

[0027] It will be readily understood by those skilled in the art that the aforementioned advantageous methods can be freely combined and superimposed without conflict.

[0028] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model. The above are only preferred embodiments of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
