Efficient ventilation device for chicken farm

Abstract

The invention provides an efficient ventilation device for a chicken farm. The efficient ventilation device comprises a connecting pipe, a first fan cover and a second fan cover, wherein guide boxes are welded to the two ends of the connecting pipe, the first fan cover and the second fan cover are both welded to the bottoms of the guide boxes, a first calandria and a second calandria are welded to the tops of the guide boxes correspondingly, valves are installed on the inner sides of the guide boxes, the top of the first calandria and the top of the second calandria are both installed exit pipes, the inner side of the connecting pipe is welded with a spiral plate, and the outer side of the connecting pipe is provided with an insulation sleeve. According to the efficient ventilation device for the chicken farm, external cold fresh air is introduced into the chicken farm through another route, heat exchange is completed in the connecting pipe through the spiral plate, and it is guaranteed that ventilation is conducted and temperature do not drop in winter; ventilation direction can be effectively guaranteed to be consistent with natural wind direction, rain and snow can be prevented from entering the calandria pipes, the ventilation efficiency can be improved through suction force generated by natural wind, it is guaranteed that the valves are sealed through sealing gaskets during rotation, air leakage is avoided and heat exchange of cold and hot air is not affected, and the efficient ventilation device is suitable for ventilation of the chicken farm.

Description

technical field [0001] The invention relates to the technical field of high-efficiency ventilation equipment, in particular to a high-efficiency ventilation device for chicken farms. Background technique [0002] In order to ensure the growth safety of the chickens in the chicken farm, it is necessary to use a high-efficiency ventilation device to ensure the safe ventilation of the chicken farm.

[0002] In order to ensure the growth safety of the chickens in the chicken farm, it is necessary to use a high-efficiency ventilation device to ensure the safe ventilation of the chicken farm. The patent application number is CN201810336341.4, which discloses a chicken farm ventilation device. The high-efficiency ventilation equipment basically has the advantages of fast ventilation speed, long continuous working time, firm structure, and long service life, which can meet the requirements for ventilation operations in chicken farms. However, for the existing high-efficiency ventilation equipment, one On the one hand, when ventilation is carried out in winter, a large amount of cold air will enter the chicken farm, and then the temperature in the chicken farm will drop rapidly, which is not conducive to ensuring the safety of chicken growth. On the other hand, in rainy and snowy weather, when natural When the wind is strong and the exhaust direction of the ventilation equipment is opposite to that of the ventilation equipment, it will not only block the ventilation of the chicken farm, but also easily cause rain and snow to enter the ventilation equipment, which is not conducive to ensuring the safe operation of the equipment. On the other hand, it is necessary to When the heat recovery is ensured by turning the valve, it is easy to cause the valve to be not tightly sealed, which will affect the heat exchange operation of cold and hot air
