Problems solved by technology

The present invention is mainly used to solve the problem that the exhaust fan used in the existing granary can only exchange the outside air with the air in the granary, and then realize the function of ventilation and ventilation of the granary. During the period of poor environmental quality, ventilation of the granary through the existing exhaust fan will lead to deterioration of the humidity and air quality in the granary, which will have an extremely bad impact on the grain in the granary

Abstract

The invention belongs to the technical field of exhaust fans, specifically a multi-mode ventilation exhaust fan for granaries, including ventilation control parts, power parts, fan blades, outer pipe body, inner pipe body and opening adjustment parts; The ventilation control part realizes that the exhaust fan is in a ventilation state, and the opening of the inner pipe body is fully opened by controlling the opening adjustment part, and the No. 1 motor is set to rotate forward at this time, and then the air outside the granary is transported to the granary through the exhaust fan Inside, the ventilation and ventilation of the granary can be realized; the exhaust fan is in a closed state by controlling the ventilation control part, and the opening of the inner pipe body is reduced by controlling the opening adjustment part, and the No. 1 motor is set to reverse at this time , and then realize that the air in the granary is drawn out through the inner tube body, and then the air drawn out by the fan blades returns to the granary through the passage between the outer tube body and the inner tube body, and then the air in the granary is internally circulated.

Description

technical field [0001] The invention belongs to the technical field of exhaust fans, in particular to a multi-mode ventilation exhaust fan for granaries. Background technique [0002] my country is a large agricultural country, and the production and storage of grain has a long history. The increase in the total amount of grain has also put forward higher requirements for grain storage, and then there has been a granary specially used to store grain, and the grain is stored in the granary. Inside, there are also certain requirements when storing grain, such as moisture resistance, heat insulation, ventilation, air tightness, insect resistance and fire resistance, etc. For ventilation, ventilation in the granary is realized through exhaust fans. [0003] Existing exhaust fans for granaries can only exchange the outside air with the air in the granary, and then realize the ventilation and ventilation of the granary. However, for areas with long-term rainy weather and poor exter...
