Description

Technical Field

[0001] This utility model relates to the field of material storage technology, and more specifically, it relates to a moisture-proof steel silo. Background Technology

[0002] Grain reserves are a crucial link in ensuring people's livelihood in my country. During the hot summer and autumn seasons, high temperatures accumulate inside grain warehouses, creating a temperature difference with the outside. Driven by this temperature difference, moisture diffuses along the direction of heat flow, which is a key reason for grain infestation and spoilage. As winter temperatures gradually cool, if the grain temperature does not drop accordingly or drops insufficiently, it will cause the grain to heat up on its own. In addition, gaps in the warehouse allow cold and humid air from the outside to enter, making it extremely easy to induce mold growth.

[0003] The following problems still exist when using existing moisture-proof steel silos:

[0004] 1. Currently, fans are commonly used to force ambient air into steel silos to cool the grain. However, the introduced air inevitably carries ambient humidity. When this humid air enters the silo and comes into contact with the cool grain pile, the moisture it carries is easily released and absorbed by the grain or adheres to the silo walls. This makes it difficult for the existing moisture-proof structure of the steel silo to effectively prevent moisture backflow, resulting in poor overall moisture-proof performance.

[0005] 2. When the fan draws in outside air for ventilation, it also brings suspended dust particles into the steel silo. With prolonged and continuous ventilation, these fine dust particles will settle and adhere in large quantities to the surface of the grain pile and the outer side of the grain particles near the air intake area, forming a significant pollution layer over time, affecting the cleanliness and appearance of the grain.

[0006] 3. When existing steel silos are ventilated using fans, the airflow is difficult to diffuse evenly within the large grain pile due to limitations such as the silo structure, grain pile resistance characteristics, and air distribution system design. This often leads to over-ventilation in some areas and under-ventilation in others, creating obvious dead zones or short circuits. This results in uneven temperature and humidity regulation within the grain pile and may even cause localized moisture condensation or heat accumulation.

[0007] In view of this, we propose a steel silo designed to prevent moisture backflow. Utility Model Content

[0019] (III) Beneficial Effects

[0020] Compared with the prior art, this utility model provides a moisture-proof steel silo with the following beneficial effects:

[0021] 1. This invention introduces external air through a negative pressure fan, forcing it to flow through the inner wall of the low-temperature support shell. The introduced air is first filtered and dust-removed, and the moisture and heat it carries are efficiently condensed and released as moisture on the cold wall, significantly reducing the humidity of the incoming air. This active dehumidification mechanism fundamentally solves the problem of moisture reabsorption inside the chamber caused by traditional ventilation.

[0022] 2. This invention utilizes a motor-driven rotating tube with ventilation holes and a rectangular tube to rotate, ensuring that the filtered air uniformly and dynamically impacts the inner wall of the low-temperature support shell, thus guaranteeing a consistent condensation and dehumidification effect. The pre-filter effectively intercepts dust and impurities in the air, significantly reducing the risk of dust adhering to grains and moisture inducing mold growth.

[0023] 3. This utility model uses a solenoid valve to automatically discharge water at regular intervals, preventing water accumulation, mold growth, or damage to the equipment. An additional insulation shell is added outside the support housing to effectively reduce cold water pipe loss, maintain a consistently low inner wall temperature, and ensure stable and efficient condensation dehumidification, especially advantageous when ambient temperature fluctuates.

[0033] Please see Figures 1-5 A moisture-proof steel silo includes support legs 1, a steel silo 2 fixedly connected to the support legs 1, a top cover 3 fixedly connected to the steel silo 2, an air guide pipe 4 embedded in the top cover 3, a support shell 5 fixedly connected to the top cover 3, a water guide pipe 6 surrounding the outer side of the support shell 5, a cover plate 7 fixedly connected to the upper part of the support shell 5, a rotating pipe 8 rotatably connected to the cover plate 7, the rotating pipe 8 having circumferentially evenly spaced ventilation holes 9, and rectangular pipes 10 circumferentially evenly spaced connected to the rotating pipe 8, the rectangular pipes 10 communicating with the ventilation holes 9, and the support shell 5 being fixedly connected to... The bottom plate 11 has an air guide pipe 4 embedded in it, and the support shell 5 is equipped with a filter structure. The top cover 3 is fixedly connected to a bend pipe 12, and the bend pipe 12 is fixedly connected to a fan 13. The bottom plate 11 is fixedly connected to two water outlet pipes 14, and a solenoid valve 15 is fixedly connected to the water outlet pipes 14. The upper side of the bottom plate 11 is provided with a frustum-shaped protrusion. The outer side of the support shell 5 is fixedly connected to an insulation shell 16, and the water guide pipe 6 is located between the support shell 5 and the insulation shell 16. The inner wall of the steel silo 2 is fixedly connected to an air distribution plate 17, and the air guide pipe 4 is fixedly connected to and connected to the air distribution plate 17.

[0034] Please see Figure 5 The filter structure includes a connecting shell 18, which is fixed to the upper side of the cover plate 7. A protective cover 19 is fixed to the top of the connecting shell 18. The connecting shell 18 is provided with through holes distributed at equal intervals in the circumference. A filter screen 20 is fixed to the through holes of the connecting shell 18. A motor 21 is fixed to the protective cover 19. A connecting frame 22 is fixed between the output shaft of the motor 21 and the rotating tube 8.

[0035] The working principle of this utility model:

[0036] When using the steel silo 2, first connect the water guide pipe 6 to the cold water circulation equipment. During the cold water circulation, low-temperature cold water circulates within the water guide pipe 6, keeping the inner wall of the support shell 5 at a low temperature. Then, start the fan 13. The fan 13 discharges the air from the bend pipe 12, creating a negative pressure state inside the steel silo 2. Outside air passes through the filter screen 20 and enters the connecting shell 18. The filter screen 20 cleans impurities from the air. The air then passes through the vent hole 9 of the rotating pipe 8 and flows along the rectangular pipe 10, finally entering the support shell 5. During the above process... When motor 21 starts, the output shaft of motor 21 drives the rotating tube 8 to rotate circumferentially through the connecting frame 22. The rotating tube 8 drives the rectangular tube 10 to rotate circumferentially, so that the air is evenly impacted on the inner wall of the support shell 5. When the hot and humid air comes into contact with the inner wall of the support shell 5, the moisture in the hot and humid air condenses on the inner wall of the support shell, thereby reducing the moisture content in the air and improving the anti-moisture effect of the steel silo 2. The condensed air flows downward along the air guide pipe 4 and finally flows outward from the air distribution plate 17. The air distribution plate 17 causes the air to flow evenly upward along the steel silo 2 and is discharged outward from the bend pipe 12.

[0037] During the above process, the insulation shell 16 reduces the amount of cold water in the water pipe 6 for insulation, ensuring the condensation effect of the support shell 5 on the hot and humid air. The condensed water droplets on the support shell flow downwards onto the base plate 11. Then, the solenoid valve 15 is activated at regular intervals to discharge the condensate from the outlet pipe 14, reducing the amount of condensate accumulated on the base plate 11.

[0038] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
