AI Technical Summary
The existing airtight ventilation system on the top of grain warehouses is highly complex in terms of sealing and ventilation adjustment, cannot be switched quickly, and has poor cooling effect during ventilation.
A device was designed that includes a top mounting ring, a sealing top cover, an air intake structure, and an air guiding structure. The device achieves rapid airtightness and ventilation adjustment by raising and lowering the sealing top cover, and uses the air guiding structure to draw in low-temperature air from the bottom for layer-by-layer cooling.
It enables rapid switching between airtightness and ventilation, improving the cooling effect when the grain silo is ventilated. It achieves more efficient cooling by having the bottom air intake come into contact with the naturally sinking cold air from the top.
