Description

Technical Field

[0001] This utility model belongs to the field of lead-acid battery technology. Specifically, it relates to a splash-proof, guide-type lead pellet feeding device. Background Technology

[0002] Before the lead powder manufacturing process in lead-acid battery production, lead ingots are cut into lead granules of approximately 20*20*30mm (weighing about 140g). These granules are then transported to a lead powder silo via a conveyor belt for grinding. During the descent of the granules, they frequently splatter due to collisions, falling outside the conveyor belt, causing material loss and safety hazards. The uncontrollable trajectory of the falling particles leads to uneven accumulation on the conveyor belt, and the significant impact causes damage to the conveyor belt, necessitating frequent replacements.

[0003] Existing technology discloses a lead pellet feeding and discharging device to solve the collision problem. It includes a conveyor belt transporting lead pellets from left to right. A longitudinal feeding channel is provided on the top left side of the conveyor belt, with a left longitudinal rail and a right longitudinal rail on the left and right sides of the channel, respectively. A left slider is located in the middle of the right side of the left longitudinal rail, and a left movable shaft is located in the middle of the left slider. A lower buffer guide plate inclined downwards to the right is connected to the right side of the left movable shaft. A right slider is located at the top left side of the right longitudinal rail, and a right movable shaft is located in the middle of the right slider. An upper buffer guide plate inclined downwards to the left is connected to the left side of the right movable shaft. The bottom end of the upper buffer guide plate is located above the top end of the lower buffer guide plate. The bottom end of the lower buffer guide plate is located above the conveyor belt. The discharge opening is located at the bottom right side of the feeding channel, above the conveyor belt. While a continuous buffer solution can solve the collision problem, the lead pellets are heavy and fall quickly, making them prone to clogging. Moreover, the current production site has a height of less than 30cm between the pelletizer and the conveyor, and the space is limited. To match the space on site, the size of this device will be very small, making it more prone to clogging and overflow. Therefore, it is not suitable for retrofitting old machines. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a splash-proof guide lead pellet feeding device that achieves directional conveying and rebound suppression of lead pellets.

[0005] A splash-proof guide type lead pellet feeding device is installed at the discharge port of a lead ingot pelletizer, including a feeding plate, a baffle, a conveyor belt and a fence;

[0006] The material feeding port of the material feeding plate is connected to the discharge port of the lead ingot pelletizer, and the discharge port extends downward to the top of the conveyor belt. Two or more straight ribs are arranged at intervals on the lower edge of the material feeding plate discharge port, dividing the material feeding plate discharge port into several material feeding channels. The straight ribs are inclined in the direction of conveyor belt transport.

[0007] The baffle is mounted on the outer periphery of the discharge plate. The baffle includes a connecting longitudinal plate, a connecting transverse plate, and a material-blocking transverse plate. The connecting transverse plate and the material-blocking transverse plate are connected to both ends of the connecting longitudinal plate to form a Z-shaped structure. The material-blocking transverse plate is located directly in front of the discharge port of the discharge plate. The transverse width of the material-blocking transverse plate is greater than the transverse width of the discharge port of the discharge plate.

[0008] The fence is located directly above the conveyor belt, and the length of the fence is greater than the lateral width of the discharge port of the material drop plate.

[0009] The straight rib forms an acute angle with the direction in which the lead pellets fall.

[0010] The angle between the straight rib and the falling direction of the lead pellet is 30°-60°.

[0011] The blanking plate has flanges at both ends that fold upwards at 90°.

[0012] The connecting horizontal plate of the baffle is fixed to the lead ingot pelletizer, the connecting vertical plate is parallel to the side wall of the discharge plate, and the baffle horizontal plate is inclined to the side away from the lead ingot pelletizer.

[0013] The clamp between the baffle plate and the connecting plate forms an obtuse angle.

[0014] The lower part of the baffle plate is connected to a double layer of wear-resistant rubber pads.

[0015] The fence is a U-shaped structure with one open end, located at the discharge end of the conveyor belt.

[0016] The gap between the fence and the conveyor belt is approximately 3-5 mm.

[0017] This invention achieves the dual functions of directional lead particle conveying and rebound suppression by setting a group of guide ribs at a specific angle at the material discharge port, combined with a combined baffle with wear-resistant rubber pads. It solves the key problems of material dispersion and splashing in traditional devices, and is particularly suitable for precise lead particle feeding in lead-acid battery production.

[0018] This utility model has a simple structure and low cost, and is suitable for on-site equipment modification. Attached Figure Description

[0019] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0020] like Figure 1The device of this utility model consists of the following core components: a material discharge plate 3, a baffle 2, a conveyor belt 7, and a fence 8. The device is installed at the discharge port of the lead ingot pelletizer 1. The material discharge plate 3 is a sloping rectangular plate. The upper end of the material inlet is connected to the discharge port of the lead ingot pelletizer 1, and the lower end of the material outlet extends downward to the top of the conveyor belt 7. The two ends of the material discharge plate 3 have folded edges that are turned upward at 90° to prevent material from slipping from the sides. Three parallel straight ribs 4 are arranged at intervals along the lower edge of the discharge port of the blanking plate 3, dividing the discharge port of the blanking plate 3 into four discharge channels. One end of the straight ribs 4 extends to be flush with the lower edge of the discharge port of the blanking plate 3. The straight ribs 4 are inclined in the direction of conveyor belt 7, and the angle between the straight ribs 4 and the direction of lead particle falling is acute. The angle design allows the lead particles to obtain horizontal velocity and reduces linear impact. Furthermore, the angle between the straight ribs 4 and the direction of lead particle falling is 30°-60°. The straight ribs 4 are Φ10mm stainless steel square ribs, and the spacing between the three straight ribs 4 is 40mm. A Z-shaped baffle 2 composed of connecting longitudinal plates, connecting transverse plates, and baffle transverse plates is installed on the outer periphery of the blanking plate 3. The baffle plate is located directly in front of the discharge port of the drop plate 3. The lateral width of the baffle plate is greater than the lateral width of the discharge port of the drop plate 3. The connecting plate of the baffle plate 2 is fixed to the lead ingot pelletizer 1. The connecting plate is parallel to the side wall of the drop plate 3. The baffle plate is inclined to the side away from the lead ingot pelletizer 1. The clamp between the baffle plate and the connecting plate is at an obtuse angle, which serves as a guide to prevent accumulation. A 20mm thick double-layer wear-resistant rubber pad 6 is connected to the lower part of the baffle plate. Holes are opened at the corresponding positions of the lower part of the baffle plate and the double-layer wear-resistant rubber pad 6, and they are pressed together with bolts and nuts. The rubber pad absorbs the kinetic energy of the impact and reduces the rebound height by more than 90%. The lower part of the double-layer wear-resistant rubber pad 6 is about 10mm above the conveyor belt. The fence 8 is located directly above the conveyor belt 7, with a gap of about 3~5mm between it and the conveyor belt. The length of the fence 8 is much greater than the lateral width of the discharge port of the drop plate 3 and is consistent with the length of the conveyor belt. The open design of the upper part of the fence and baffle facilitates manual intervention in abnormal situations. The fence 8 is a U-shaped structure with one open end, located at the discharge end of the conveyor belt 7. The fence 8 is supported by a support frame (not shown in the diagram, which is a standard method). Figure 1 The middle arrow indicates the conveying direction of conveyor belt 7.

[0021] During operation, lead pellets exiting from lead ingot pelletizer 1 slide down along the feed plate 3, are guided by the straight guide bar 4, and then decelerated and fall onto the conveyor belt. During the process, lead pellets that collide and splash are blocked by rubber pads and fall back onto the conveyor belt. A small number of lead pellets that fall onto the conveyor belt and collide are blocked by the conveyor belt fence and fall back onto the conveyor belt. Finally, they are conveyed to the next process.
