Description

Technical Field

[0001] This utility model relates to the field of buffer bin technology, and in particular to a small material buffer bin for preventing cross-contamination. Background Technology

[0002] Small material buffer silos are key equipment used for temporary storage and transfer of materials in industrial production. Their core function is to coordinate the material handling rhythm of upstream and downstream processes and ensure the stable and efficient operation of the production process. In the production of food, feed, chemical, and building materials industries, the material output may be intermittent and fluctuating due to the intervals of material feeding in the process and the differences in equipment start-up and shutdown. Therefore, buffer silos are needed to provide a continuous and stable supply of materials.

[0003] The buffer silo can serve as an intermediate adjustment station. When the upstream equipment's capacity is higher than that of the downstream equipment, excess materials are temporarily stored in the buffer silo. When the downstream equipment's material demand exceeds the upstream's immediate capacity, the buffer silo releases the stored materials to replenish them, ensuring that the equipment operates at full capacity, thereby improving overall production efficiency.

[0004] While buffer silos play a crucial coordinating role in industrial production, they involve material storage, conveying, and equipment linkage. During use, small materials within the buffer silo are prone to lumps due to gravity compaction, electrostatic adsorption, or humidity changes, which can clog the discharge port, causing unloading interruptions or sudden material spills, resulting in production stoppages or measurement deviations. Furthermore, residues from previous batches of material remain on the inner walls or corners of the buffer silo, mixing with new batches. This is especially problematic during multi-product production transitions, leading to substandard product purity and quality. Therefore, a small material buffer silo designed to prevent cross-contamination is proposed to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a small material buffer bin to prevent cross-contamination, aiming to improve the problem of the inability to quickly clean the buffer bin in the prior art.

[0022] 1. In this utility model, gas is blown into the air inlet pipe through an external air source. The gas is blown out through the air inlet through the connecting air pipe and the jet pipe. The gas causes the jet pipe to drive the connecting air pipe and the air inlet pipe to rotate. The rotating connecting air pipe drives the scraper to rotate. The scraper is pressed against the inner wall of the bin by a spring. The rotating scraper scrapes the inner wall of the bin to clean it.

This allows for precise control of the discharge amount and significantly improves work efficiency. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-4 This utility model provides an embodiment of a small material buffer bin to prevent cross-contamination, comprising a bin body 1 for storing small materials. A feed pipe 2 is installed at the top of the bin body 1, allowing material to be added to the bin body 1. Adding material solely through the feed pipe 2 significantly reduces contamination of the small materials inside the bin body 1 by external dust. An air inlet pipe 3 is rotatably connected to the middle of the bin body 1, and the air inlet pipe 3 is connected to an external air source. The external air source includes components such as an air pump, a delivery pipe, and a control valve, all of which are prior art and not improvements to this application. Without going into too much detail, a cleaning mechanism is installed on the outside of the air inlet pipe 3. The cleaning mechanism cleans the inside of the chamber 1. The bottom of the chamber 1 is fixedly connected to the discharge pipe 14. The buffer material is discharged through the discharge pipe 14. The bottom of the discharge pipe 14 is fixedly connected to the fixing block 15. The fixing block 15 is equipped with a moving mechanism. The fixing block 15 connects the moving mechanism to the bottom of the discharge pipe 14. The moving mechanism opens and closes the discharge pipe 14 to precisely control the amount of material discharged. The outside of the chamber 1 is fixedly connected to the support frame 22, which provides stable support for the entire buffer chamber.

[0033] The cleaning mechanism includes a drive assembly and a telescopic assembly. The telescopic assembly includes a connecting air pipe 4, which is fixedly connected to the outside of the air inlet pipe 3. The air inlet pipe 3 is rotatably connected to the middle of the chamber 1. When the air inlet pipe 3 rotates, it drives the connecting air pipe 4 to rotate. The connecting air pipe 4 has a sliding groove 8 inside, and a spring 7 is installed inside the sliding groove 8. A sliding rod 9 is fixedly installed at one end of the spring 7. The spring 7 compresses the sliding rod 9, causing the sliding rod 9 to move within the sliding groove 8. A scraper 10 is fixedly connected to the other end of the sliding rod 9. The spring 7 compresses the scraper 10 against the inner wall of the rack 1 through the sliding rod 9, so that when the connecting air pipe 4 rotates, it drives the scraper 10 to rotate, thereby causing the scraper 10 to scrape and clean the inner wall of the chamber 1.

[0034] The drive assembly includes a jet pipe 5, which is fixedly connected to the outside of the connecting air pipe 4. A vent hole 11 is provided on the outside of the air inlet pipe 3, connecting the connecting air pipe 4 and the air inlet pipe 3. When the air inlet pipe 3 is connected to an external air source, gas enters the connecting air pipe 4 and the jet pipe 5 through the vent hole 11. Multiple jet holes 6 are provided on the outside of the jet pipe 5, and the gas entering the jet pipe 5 is discharged through the jet holes 6. At this time, the gas pushes the jet pipe 5 to rotate, and the rotating jet pipe 5 drives the connecting air pipe 4 and the air inlet pipe 3 to rotate. A connecting rod 12 is fixedly connected to the end of the air inlet pipe 3. The rotating air inlet pipe 3 drives the connecting rod 12 to rotate. A fixing frame 13 is fixedly connected to the outside of the connecting rod 12. The rotating connecting rod 12 drives the fixing frame 13 to rotate. The rotating fixing frame 13 can push and break up small materials, preventing them from being compressed into clumps by gravity during buffering, thus blocking the discharge pipe 14, causing interruption of material feeding, and stopping production.

[0035] Reference Figure 1 , Figure 2 and Figure 5 The moving mechanism includes a sliding assembly and a driving assembly. The driving assembly includes a motor 16, which is fixedly connected to the outside of the fixed block 15. A bevel gear 17 is fixedly connected to the output end of the motor 16. Starting the motor 16 can drive the bevel gear 17 to rotate. A bidirectional threaded rod 19 is rotatably connected inside the fixed block 15. A bevel gear 18 is fixedly connected to the outer periphery of the bidirectional threaded rod 19. The bevel gear 18 meshes with the bevel gear 17. The rotation of the bevel gear 18 through the rotation of the bevel gear 17 causes the bidirectional threaded rod 19 to rotate. The sliding assembly... The system includes a slider 20, which is threadedly connected to the outer periphery of a bidirectional threaded rod 19. When the bidirectional threaded rod 19 rotates, it drives the slider 20 to move. A stop block 21 is fixedly connected to the outer side of the slider 20. A second groove 23 is opened inside the fixed block 15. The stop block 21 is slidably connected to the inside of the second groove 23. The moving slider 20 drives the stop block 21 to move inside the second groove 23, thereby achieving the closing and opening of the discharge pipe 14. This allows for precise control of the opening size of the discharge pipe 14, thereby controlling the amount of material discharged and significantly improving work efficiency.

[0036] Working principle: First, start the motor 16 to drive the bevel gear 17 to rotate. The rotating bevel gear 17 drives the bevel gear 18 to rotate, thereby causing the bidirectional threaded rod 19 to rotate. The rotating bidirectional threaded rod 19 drives the slider 20 to move. The moving slider 20 drives the stop block 21 to move, thereby blocking the discharge pipe 14. Small materials can be transported through the feed pipe 2 to the silo 1 for buffering.

[0037] When external material needs to be discharged, the motor 16 drives the slider 20 to move a certain distance, opening the discharge pipe 14. This allows for precise control of the discharge volume, significantly improving work efficiency. Simultaneously, the air inlet pipe 3 connects to an external air source, blowing in gas. The gas is then blown out through the air outlet 6 via the connecting air pipe 4 and the air jet pipe 5. The gas causes the air jet pipe 5 to rotate, which in turn drives the connecting air pipe 4 and the air inlet pipe 3. The rotating connecting air pipe 4 then rotates the scraper 19. The scraper 19 is held against the inner wall of the bin 1 by the spring 7. The rotating scraper 19 scrapes the inner wall of the bin 1, cleaning it. Combined with the gas, this causes small materials to fall and be discharged, quickly cleaning the interior and reducing contamination of the next batch of materials, thus significantly improving work efficiency.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
