SU1392010A2 - Arrangement for introducing loose material into horizontal pipeline of pneumatic transport installation - Google Patents

Abstract

The invention relates to pneumatic equipment. The purpose of the invention is to increase the efficiency and reliability of work. The device comprises a valve 5 for shutting off the nozzle-diffuser 4, a pipeline 22 with a shutter 23 connecting the dead piston cavity 21 with the loading chamber 2, which supplies the material to the pneumatic transport line 1. The suction (ejected) flow of the transporting air passing through the rotary cavity 21 creates a vacuum in it. The pressure difference between the working chamber (in front of the piston) and behind-. the piston cavity causes the pistons 15 to move together with the rod 9 and the cylindrical yoke 10 and opens the opening 8 for feeding the material into the loading chamber 2.

The drawing shows the device, a section j general view

The device contains a pipeline I line of pneumatic transport., Cylindrical-EU-. which boot coder 2, in which the regulator body 3 and the nozzle-diffuser 4 separated from it, with the valve 5 are actuated 6. I

The regulator 3 in the cylindrical cage with OK-NOM 7 WFC material input through the opening 8 into the loading chamber 2 is mounted on the rod 9 with the bottom cover 10 with four openings 11 (for free passage of the transporting air into the pneumatic conveying line) e with four supporting lugs 12, providing access to the stream of Euzdu ha between the border 3 and the wall of the loading chamber. The actuator 6 contains a chamber of working pressure (atmospheric) 13 with a nozzle 14,) a piston 15 fixedly mounted on the rod 9, an elastic element 16, a rod 9 with a regulating member 3 at one end., A supporting piston 17 to a freely sliding sleeve 18 s elastic element 19 on the other. In the original nut 20, there is a hole for supplying the conveyor to the e-piston. 2 5 cavity formed by the piston.

15% of the side and rear walls of the loading chamber, and through the bypass branch 22 with the gate 23 into the loading chamber 2. A comb 24 for connecting the auxiliary mechanism is placed outside on the front part of the loading chamber.

The device works as follows.

The pipe 14 is connected with atmospheric air, the valve 5 closes the diffuser nozzle 9, the valve 23 is open. A pressure drop LP is created between the rear wall of the piston cavity 21, where the pressure is below atmospheric, and a section of the pipeline at the outlet, where the pressure is equal to atmospheric. In the working chamber 13, which communicates with the atmosphere through the pipe 14, a pressure equal to the atmospheric pressure is always maintained. Therefore, the same pressure differential dP acts on the piston 15, which displaces the piston 15 to the right with the rod 9 and (the cylindrical yoke 10 opens the opening 8 for feeding material the charging chamber 2 through the opening 7. As the material enters the pneumatic conveying line I, the pressure drop changes up to the specified mode of operation of the pneumatic transport.

The optimal mode of operation of the pneumatic conveying is ensured by the choice of the characteristics of the elastic element 16, the shape and size of the hole 7 and the holes in the gland nut 20.

In case of accidental blockage of the pipe material with water, the pressure in the bursting cavity 21 is equalized with the pressure in the working chamber 13, i.e. atmospheric, and the piston 15 under the action of the third element 16 is shifted to the left to its original position, and the casing 3 closes the opening 8s, stopping
