The positive pressure air shut-off device includes an air shut-off motor connected to the air shut-off device. The air shut-off device is installed at the discharge port of the silo. The air shut-off device is connected to the air supply duct and is equipped with a Roots blower at one end of the air supply duct. The characteristic is: : There is an air outlet chamber at the transmission parts at both ends of the air shutter. An air inlet is opened at the upper part of the air chamber. An air outlet is opened on the shell of the air supply duct near one end of the Roots blower. The air outlet passes through a bifurcated The air pipes are respectively connected to the air inlets at the drive shafts at both ends of the air shutter, and the wind force in the air supply duct is used to prevent the air shutter from blowing upward to form wind resistance and seal the air shutter. Compared with the existing technology, the utility model has significant advantages and beneficial effects: the positive pressure-resistant air shutoff device is installed at the discharge port of the discharge ash bin, which can prevent the air from entering the discharge port in the opposite direction during material transportation. The material ash bin affects the cutting speed and quantity.
The air shut-off device is also called the fan shut-off discharge valve, dust discharge valve star-shaped discharge device. The air shutoff device is an important piece of equipment in the pneumatic conveying and ventilation dust removal network. Its main function is to continuously discharge the materials in the unloader or dust collector in a timely manner while ensuring that the pressure inside the equipment is not exposed to the normal pressure environment.
Scope of application
It is widely used in the pneumatic transportation of rice milling, flour milling, feed machinery, chemical, pharmaceutical, tobacco, metallurgy, cement and dust removal and other industry equipment and the unloading of pipe network pressure conditions. It plays the role of continuous discharge and air tightness for powdery, granular, flake and fiber materials under positive and negative pressure conditions.
