Description

Technical Field

[0001] This utility model relates to the technical field of storage warehouse ventilation devices, and more specifically, to a storage warehouse moisture-proof ventilation device. Background Technology

[0002] Soybean meal is rich in protein and amino acids, making it a crucial raw material for the feed processing industry. However, soybean meal is highly hygroscopic and easily affected by ambient humidity during storage. If the storage environment is too humid, the soybean meal will not only become damp and clump together, resulting in poor flowability and causing great inconvenience to subsequent transportation, measurement, and processing, but it will also create conditions for the growth of microorganisms such as mold. The large-scale reproduction of mold will not only consume the nutrients in the soybean meal and reduce its nutritional value, but may also produce harmful substances such as aflatoxin, which seriously threaten animal health and may even pose a potential risk to human health through the food chain.

[0003] In addition, poor ventilation in the storage silo can lead to poor air circulation, heat and moisture buildup, which can further accelerate the spoilage of soybean meal. Moreover, insufficient ventilation may also cause odors, affecting the quality of soybean meal and reducing its suitability for use in feed formulations.

[0004] Currently, most soybean meal feed processing enterprises use relatively rudimentary moisture-proof and ventilation measures for their storage warehouses. Some enterprises rely solely on natural ventilation to regulate humidity and air circulation within the warehouse. This method is highly susceptible to weather and seasonal variations. In high humidity or windless conditions, ventilation effectiveness is severely limited, making it difficult to effectively control humidity within the warehouse and impacting the storage of soybean meal feed. Therefore, we propose a moisture-proof and ventilation device for storage warehouses. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0027] Please see Figures 1-4 This utility model provides a technical solution: a moisture-proof ventilation device for storage warehouse, including an air outlet device 1 and an air inlet device 2. The air outlet device 1 consists of an air outlet pipe 10 and a first fan 12 installed in the air outlet pipe 10. When the first fan 12 is working, it can discharge the humid and polluted air in the storage warehouse through the air outlet pipe 10 to the outside of the warehouse, realize the directional discharge of air in the warehouse, effectively improve the air environment in the storage warehouse, and reduce the moisture content.

[0028] Specifically, the air inlet device 2 consists of a drying cylinder 20 and an air inlet pipe 21 fixedly installed on one side plate of the drying cylinder 20. A second fan 22 is fixedly installed on the inner wall of the air inlet pipe 21. A conical hood 24 is fixedly installed at the bottom of the drying cylinder 20. An inner moisture-absorbing particle blocking net 241 is fixedly installed on each side plate of the conical hood 24. Moisture-absorbing molecular sieves are set inside the drying cylinder 20 and the conical hood 24, so that outside air enters the drying cylinder 20 along the inner moisture-absorbing particle blocking net 241 under the action of the second fan 22. After drying, it enters the storage chamber to replenish the chamber with dry fresh air, inhibit the soybean meal from getting damp, and the conical hood 24 guides the airflow to fully contact the moisture-absorbing particles, enhancing the drying effect of the air.

[0029] In this embodiment, a discharge pipe 25 is fixedly installed at the bottom end of the conical cover 24, and a discharge valve 251 is fixedly installed on the discharge pipe 25, so that the failed moisture-absorbing particles can be discharged through the discharge pipe 25, which facilitates the replacement of moisture-absorbing particles and maintains the drying performance of the drying cylinder 20. A feed pipe 26 is fixedly installed on the top surface of the drying cylinder 20, which facilitates the replenishment of moisture-absorbing particles into the drying cylinder 20 and ensures the continuous and stable operation of the drying cylinder 20. A moisture discharge pipe 28 is fixedly installed at the top of the feed pipe 26, and a third butterfly valve 281 is fixedly installed on the moisture discharge pipe 28. The moisture discharge pipe 28 can be used to discharge moisture during the subsequent regeneration operation of the moisture-absorbing particles.

[0030] Specifically, a first butterfly valve 11 is fixedly installed on the air outlet duct 10, which can flexibly control the opening and closing of the air outlet device 1, and facilitate the adjustment of ventilation volume according to the actual situation in the storage compartment; a first baffle 13 can be detachably installed at both ends of the air outlet duct 10, which can prevent foreign objects from entering the air outlet duct 10, ensure the normal operation of the first fan 12, and facilitate the cleaning and replacement of the first baffle 13.

[0031] Furthermore, the inner wall of the conical hood 24 is inclined downward at 45°~60°, and the discharge pipe 25 is vertically arranged, so that the failed moisture-absorbing particles can be smoothly discharged through the discharge pipe 25 under the action of gravity, and the moisture-absorbing particles are prevented from accumulating inside the conical hood 24.

[0032] In addition, a second butterfly valve 211 is fixedly installed on the air inlet pipe 21, which can control the on / off of the air inlet device 2 and flexibly adjust the air intake volume; a second baffle 23 is detachably connected to the air outlet end of the air inlet pipe 21. Both the second baffle 23 and the first baffle 13 are mesh structures. The second baffle 23 and the first baffle 13 are fixed to the corresponding pipe body by multiple fastening screws to prevent foreign objects from entering the storage chamber, ensure the quality of stored soybean meal, and facilitate the maintenance of the second baffle 23.

[0033] It is worth noting that an electric heating rod 27 is installed inside the feed pipe 26. The bottom end of the electric heating rod 27 extends into the conical cover 24, so that the electric heating rod 27 heats and regenerates the moisture-absorbing particles, extending the service life of the moisture-absorbing particles and reducing the cost of use. During the regeneration process, the moisture can be discharged outward through the moisture discharge pipe 28.

[0034] It is worth noting that the feed tube 26 is provided with a wiring hole 261. The wiring hole 261 and the cable are sealed with waterproof glue to facilitate wiring operations and ensure airtightness. A fixing bracket 271 is fixedly installed on the top shell of the electric heating rod 27. The fixing bracket 271 is fixedly installed on the inner wall of the feed tube 26 by multiple fastening screws to facilitate fixing, installation and disassembly operations.

[0035] Finally, it should be noted that the electric heating rod 27, the first fan 12, and the second fan 22 involved in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the spare parts of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the matching controller and power supply, are connected by wires. The specific connection method should refer to the working principle in this utility model. The electrical connection between each electrical component is completed in the order of operation. The detailed connection method is a technology known in the art.

[0036] When using the moisture-proof and ventilation device for the storage chamber of this utility model, the air outlet pipe 10 and the air inlet pipe 21 are fixedly installed on the corresponding positions on the wall of the storage chamber. Then, the feed pipe 26 is opened to fill the drying cylinder 20 and the conical cover 24 with moisture-absorbing molecular sieves. Subsequently, the first butterfly valve 11 and the second butterfly valve 211 are opened, and the first fan 12 and the second fan 22 are started. The first fan 12 discharges the humid and polluted air in the chamber through the air outlet pipe 10. The second fan 22 introduces outside air into the drying cylinder 20. The air enters along the inner moisture-absorbing particle blocking net 241 and comes into full contact with the internal moisture-absorbing molecular sieves. The dry air then enters the storage chamber, realizing air intake on one side and air exhaust on the other side.

[0037] When the hygroscopic molecular sieve fails, the second fan 22 and the second butterfly valve 211 are shut off, and the discharge valve 251 is opened. Under the action of gravity, the failed hygroscopic molecular sieve is discharged along the inner wall of the conical cover 24 through the vertical discharge pipe 25. After discharge, the discharge valve 251 is closed, and a new hygroscopic molecular sieve is replenished from the feed pipe 26.

[0038] If the hygroscopic molecular sieve needs to be regenerated, open the third butterfly valve 281, start the electric heating rod 27, heat the hygroscopic molecular sieve inside the conical shroud 24, and the moisture generated during regeneration is discharged through the moisture discharge pipe 28.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
