A fruit pit screening device for activated carbon production

Abstract

This utility model relates to the field of fruit pit screening technology and proposes a fruit pit screening device for activated carbon production. After the fruit pit material is put into the feeding storage hopper, it accumulates and is stored at the upper end of the feeding storage hopper. During the storage process, it falls downward along the inclined surface of the upper part of the feeding baffle. The middle position of the two feeding baffles forms a funnel-shaped opening, which limits the number of fruit pits that can pass through per unit time. At the inclined surface of the middle part of the two feeding baffles, an elastic buffer baffle is formed by installing a first spring and a buffer baffle. During the fall, the fruit pits fall onto the surface of the buffer baffle. The buffer baffle elastically contracts by compressing the first spring to form a buffer. The operator can directly put the fruit pits into the feeding storage hopper to complete the uniform and quantitative feeding, which saves the labor intensity of the operator. Moreover, the elastic buffer baffle function avoids the splashing of fruit pits and ensures that the feeding work is stable and efficient.

Description

Technical Field

[0001] This utility model relates to the field of fruit kernel screening technology, specifically a fruit kernel screening device for activated carbon production. Background Technology

[0002] In the activated carbon production process, fruit pits are a key raw material, and their quality and characteristics play a decisive role in the quality and performance of the final activated carbon product. With the widespread application of activated carbon in many fields such as environmental protection, chemical industry, and food, the market demand for the quality and quantity of activated carbon is increasing, which places higher demands on the fruit pit screening process.

[0003] Currently, various methods are used to screen fruit pits by size. Some methods use rollers, which use multiple rotating rollers to screen the pits under the action of gravity and centrifugal force. The rollers rotate synchronously through synchronous belts and pulleys. Circular holes are made inside the rollers. When the size of the pit is smaller than the size of the circular hole, the pit will leak out under the action of gravity. Multiple rollers can screen various sizes. In order to make the pits enter the screening area of ​​the roller more evenly, a roller conveyor is usually set at the front end of the roller for feeding.

[0004] However, the above method has a prominent problem: because the spherical fruit pits are mostly arc-shaped, the existing roller conveyors usually lack a buffer and uniform feeding function during the feeding process. During the fruit pit feeding process, the workers need to pay attention to the feeding speed of the fruit pits to avoid the spherical fruit pits falling and accumulating suddenly, causing splashing and popping. This not only prolongs the overall feeding time and affects the processing efficiency, but also increases the workload of the workers who have to hold the materials for a long time.

[0005] Therefore, a fruit pit screening device for activated carbon production is proposed. By using an adjustable baffle for the feeding opening in conjunction with an elastic buffer baffle, the operator can directly put the fruit pits into the feeding storage hopper to complete the uniform and quantitative feeding. This saves the operator's labor intensity, and the elastic buffer baffle function avoids the fruit pits from splashing, ensuring that the feeding work is carried out stably and efficiently, thus solving the above problems.

This device solves the problem that workers need to pay attention to the feeding speed of fruit pits to avoid the phenomenon of spherical fruit pits suddenly falling and accumulating, causing splashing and popping. This not only prolongs the overall feeding time and affects processing efficiency, but also increases the workload of workers who have to hold the materials for a long time for feeding.

[0017] Beneficial effects

[0018] Compared with the prior art, this utility model provides a fruit pit screening device for activated carbon production, which has the following beneficial effects:

[0019] After the fruit pits are put into the feeding and storage hopper, they accumulate at the top of the hopper and fall downwards along the inclined surface of the upper part of the feeding baffle during storage. The funnel-shaped opening formed in the middle of the two feeding baffles limits the number of fruit pits that can pass through per unit time. Furthermore, an elastic buffer baffle is formed on the inclined surface in the middle of the two feeding baffles by installing a first spring and a buffer baffle. When the fruit pits fall onto the surface of the buffer baffle, the buffer baffle elastically contracts by compressing the first spring, thus providing cushioning. Workers can directly put the fruit pits into the feeding and storage hopper to complete the uniform and quantitative feeding, which saves the labor intensity of the workers. Moreover, the elastic buffer baffle function prevents the fruit pits from splashing, ensuring that the feeding work is stable and efficient. Attached Figure Description

[0031] Please see Figures 1-4 Figure 1 illustrates a fruit kernel screening device for activated carbon production, comprising a screening device body 1. Fruit kernel screening is of great significance in activated carbon production. Firstly, it ensures product quality by allowing the fruit kernels to react uniformly during carbonization and activation, reducing the impact of impurities, and producing activated carbon with stable performance and high purity. Secondly, to improve production efficiency, ensure the fruit kernels are compatible with the equipment, optimize operation, reduce clogging, and shorten the production cycle, we select the screening device body 1 to screen the fruit kernels by size.

[0032] The main body 1 of the screening device is mainly used for screening spherical fruit pits (such as walnut shells, olive pits, lychee pits, etc.). The screening process can be roughly divided into two steps. First, a roller conveyor assembly is installed on the upper part of the main body 1 near the feeding storage hopper 2. After the fruit pits are placed in the roller conveyor assembly, they are conveyed to one side by rotating rollers. On the side of the main body 1 away from the roller conveyor assembly, three rollers with different circular grooves are installed (the synchronous rotation of the three rollers is achieved by components such as motors, synchronous pulleys, and synchronous belts). These are four channels for unloading after screening. After the fruit pits are conveyed to one side of the rollers, the fruit pits smaller than the circular grooves inside the rollers will be exposed downwards along the circular grooves, while the larger ones will be continuously conveyed forward. Through the above process, fruit pits of different sizes are screened to prepare for the subsequent production of activated carbon.

[0033] During the actual screening process, we discovered a prominent issue: spherical fruit pits, due to their rounded edges, lack a buffering and uniform feeding mechanism. During the feeding process, workers must pay close attention to the feeding speed to prevent sudden drops and accumulations that could cause splashing and ejection. This not only prolongs the overall feeding time and affects processing efficiency, but also increases the workload for workers who have to hold the materials for extended periods.

[0034] Therefore, to solve the above problems, we added a baffle mechanism to the feeding process. A feeding storage hopper 2 is fixedly connected to the upper end of the main body 1 of the screening device. The baffle mechanism includes two feeding baffles 3, two sets of first springs 4, and two buffer baffles 5. Both feeding baffles 3 are slidably connected inside the feeding storage hopper 2. The upper ends of both feeding baffles 3 are designed with rounded chamfers. The two sets of first springs 4 are fixedly connected to the outer surfaces of the two feeding baffles 3, and the two buffer baffles 5 are fixedly connected to the outer surfaces of the two sets of first springs 4. The main body 1 of the screening device is equipped with a feeding storage hopper 2 on one side for feeding. After the fruit pit material is put into the feeding storage hopper 2, it falls downward into the roller conveyor assembly to complete the conveying. Inside the feeding storage hopper 2, there are two sliding and adjustable feeding baffles 3. The two feeding baffles 3 are symmetrically inclined in the middle to form a funnel-shaped opening. The upper ends of the two feeding baffles 3 are flat to provide space for holding fruit pits. The upper ends of the two feeding baffles 3 are rounded and chamfered to form a rounded slope to guide the fruit pits to slide down.

[0035] After the fruit pits are put into the feeding and storage hopper 2, they accumulate and are stored at the upper part of the hopper. During storage, they fall downwards along the inclined surface of the upper part of the feeding baffle 3. The funnel-shaped opening formed in the middle of the two feeding baffles 3 limits the number of fruit pits that can pass through per unit time. Furthermore, an elastic buffer baffle is formed on the inclined surface in the middle of the two feeding baffles 3 by installing a first spring 4 and a buffer baffle 5. When the fruit pits fall onto the surface of the buffer baffle 5, the buffer baffle 5 elastically contracts by compressing the first spring 4 to form a buffer. The staff can directly put the fruit pits into the feeding and storage hopper 2 to complete the uniform and quantitative feeding, which saves the labor intensity of the staff. Moreover, the elastic buffer baffle function prevents the fruit pits from splashing, ensuring that the feeding work is stable and efficient.

[0036] During the use of the baffle mechanism, considering the differences in fruit kernel size and the fact that the device needs to screen various types of fruit kernels, we have set up a threaded mechanism for adjusting the spacing between the two feed baffles 3. The threaded mechanism includes a bidirectional lead screw 6, which is threadedly connected inside the two feed baffles 3. The bidirectional lead screw 6 is rotatably connected inside the main body 1 of the screening device and the feeding storage hopper 2. A set of second springs 7 is fixedly connected to the outer surfaces of the two feed baffles 3 on opposite sides. Both sets of second springs 7 are fixedly connected to the inner surface of the feeding storage hopper 2. Before feeding, the operator can rotate the bidirectional lead screw 6 to drive the two feed baffles 3 to slide in opposite directions, thereby adjusting the size of the funnel-shaped opening formed in the middle. The second springs 7 are installed between the two feed baffles 3 and the feeding storage hopper 2. The second springs 7 are used to provide resistance when increasing the opening and to provide assistance when decreasing the opening. This design mainly takes into account that the fruit kernel size is usually small, and avoids the operator from over-rotating and causing the opening to be too large, requiring repeated adjustments.

[0037] When installing the feeding storage hopper 2 inside the main body 1 of the screening device, we selected a fixing mechanism, which includes a bolt rod 8, a nut 9, and an internal threaded cover 11. The bolt rod 8 is located inside the main body 1 of the screening device and the feeding storage hopper 2. The nut 9 is threadedly connected to the outer surface of the bolt rod 8 and is located inside the feeding storage hopper 2. The internal threaded cover 11 is threadedly connected to the outer surface of the bolt rod 8. After the bolt rod 8 is inserted into the feeding storage hopper 2 through the upper support of the main body 1 of the screening device, it is tightened and fixed by screwing on the nut 9. To provide space for screwing on the nut 9, a circular opening is provided inside the feeding storage hopper 2 for inserting the nut 9. After the threaded installation is stable, the circular opening inside the feeding storage hopper 2 is blocked by screwing on the internal threaded cover 11 on the surface of the bolt rod 8 to prevent fruit pits from falling into the circular opening of the feeding storage hopper 2 and causing blockage during the feeding process.
