Abstract

The invention relates to pneumatic conveying and can be used for transporting grain and associated separation of associated dust. The purpose of the invention is to increase the efficiency of dust separation. Airgun for bulk materials contains an air distribution grill 1, air supply 2 and transporting 3 channels, dust collector 4, nozzles 5, charging 6 and receiving 7 devices, valve 8, fan 9, dust collector 10 with air lock 11, discharge 12 and suction 13 air lines , valve 14, vertical valve 15, air suction regulator 16. The use of two sections of the air-conducting channel 2 is caused by the need to move and blow the material through the air distribution grill with air from one section of the channel and blow air through the moving layer of material through the nozzles 5 from the other section of the channel. At the same time, the amount and pressure of the air in the sections are established by means of a valve 14 located at the junction of the discharge air duct with the air inlet duct. The presence at the end of the conveying channel 3 of the vertical flap 15 is due to the need to create a moving layer of material (grain) of a certain height, which depends on the type of material, which makes it possible to regulate the time it is treated with air in the air duct and thereby increase the efficiency of dust release. 1 hp ff. 1 il.

Dusty dispersed material

(grain) through the loading device 6 enters the air distribution grill 1 with the height of the blown layer, installed by the valve 8 and the vertical flap 13, is blown with air coming from the air passage channel 2, goes into a fluidized state and moves along the air distribution grid, which can be placed both horizontally and with an angle of inclination to the horizontal plane, to the receiving device 7.

At the same time, dust particles are removed from the moving air-blown layer and, getting into dust collector A, are carried away by air flow into the suction air duct 13 and dust collector 10, in which air is cleaned from dust, passes through the fan 9 and through the discharge air duct 12 flows through the valve 1A into the air inlet duct 2 section. From the air inlet duct 2, air enters the nozzle. 5, from which is directed through the holes 17 at an angle of 45-90 in the opposite direction to the layer of movement of the filter and the washing nozzle 5 of dispersed material (grain), removal of dust particles from it, which enter the dust receptacle 4. In addition, The nozzles 5 are mixed, and this contributes more efficiently to the release of dust from it. If necessary, air from the surrounding air is introduced into the closed complex for cleaning the material from dust by the air intake controller 16. The dust extracted from the air into the dust collector 10 is discharged through an isyuzy shutter 11. I

The use of two sections of the air passage channel 2 is caused by the need to move and blow the material through the air distribution grill with air from one channel section and blow air through the base layer of the material through nozzles 5 from the other channel section. With this amount. and the sticking of air in the sections is established by means of a valve 14 located at the junction of the discharge air duct with the air supply duct.

The presence at the end of the transport channel 3 of the vertical valve 15 is due to the need to create a moving layer of material (grain)

of a certain height, which depends on the type of material, which makes it possible to regulate the time it is treated with air in the airblocks.
