A device for sucking and exhausting pigs

摘要

The present invention relates to a suction and exhaust device for discharging the inside air of a pig and for introducing outside air into the inside of a pig, which allows the intake and exhaust at the same time to be performed simultaneously, while the sucked outside air is indirectly heated So as to be introduced.;In the present invention, an air inlet pipe is formed outside the exhaust pipe with an exhaust fan, an air inlet pipe with an intake fan is installed, and an intake pipe is installed horizontally on the upper side of the air inlet pipe. The intake and exhaust operation is performed by the separate configuration of the intake fan and the exhaust fan. When the temperature is low, the outside air is heated indirectly from the upper part of the pile, The outside air can be introduced without dropping the temperature, and the introduced outside air can be discharged downward, so that the outside air can be introduced into the pile fast.
