he air screen cleaner can be widely used for cleaning and processing the seeds of various crops such as wheat, rice, corn, barley and peas.
Principle of operation
When the material enters the air screen from the feed hopper, it uniformly enters the upper screen sheet under the action of the electric vibrator or the feed roller, and is influenced by the air flow of the front suction duct. Light sundries are sucked into the front settling chamber and then settle to the bottom, and are sent to the discharge port by the screw conveyor for fine selection in width or thickness. Before being discharged, the selected grains are blown into the settling chamber by the updraft blown by the fan, and then settle to the bottom, and are discharged from the discharge port by the screw conveyor. Because the rear suction duct is generally high, those grains with larger specific gravity among the remaining grains may fall back into the good seeds before being blown into the rear settling chamber, which reduces the selection quality. Therefore, the lower part of the rear suction duct is equipped with an auxiliary discharge port and a baffle with adjustable height to remove this part of the grains, and finally the processed good seeds are discharged from the main discharge port of the machine.
Matters need attention
1.Turn the knob to the "0" position before starting the variable frequency speed regulator, and then gradually increase it until the fan speed is satisfactory after the machine runs normally, so as to ensure the normal operation of the fan.
2. The equipment should be installed in properly reinforced reinforced concrete.
