Description

This invention relates to the pneumatic transport of bulk materials, mainly domestic waste.

The purpose of the invention is to increase reliability.

The drawing shows the installation diagram.

A vacuum pneumatic conveying installation for bulk materials, mainly household waste, contains a main pipeline 1, and branch pipes 2 and 3, respectively, are connected at points A, B, C, D. Moreover, point C of the connection of discharge pipe 3 is located on a segment pipeline AB.

The discharge pipe (2.3) has air intake valves 4 and 5, respectively, and loading valves, respectively 6-11 and 12-17. The installation also contains the station 18 garbage disposal and a vacuum pump 19 connected to each other and with the main pipeline 1.

Near point B in the discharge pipe 2 and the main pipeline 1 in the direction opposite to the waste disposal station 18, full bore valves 20 and 21 are installed and immediately behind the lower air intake valve 4 and an additional air intake valve 22. Near point D on the exhaust pipe 3 and main pipeline 1 installed full bore valves respectively. 23 and 24, an intake valve 5 and an additional intake valve 25. In the middle of the exhaust pipes 2 and 3, additional inlet valves 26 and 27 are installed at the point E and at point F. Others can also be connected to the main pipeline 1 branches (dashed line).

The installation works as follows.

In the initial position, all full bore valves and air intake valves are closed. When transporting household waste from the garbage chutes with garbage-loading valves 14-17 located on the exhaust pipe 3, the air intake valve 27 is opened and a poly-passage is passed to the valve 23. On the section of the exhaust pipe 3 FD and the section of the trunk pipeline 1 from point D to the station 18 waste removal. The vacuum pump 19 creates a stream of discharged air to which household waste is transported. After the transportation of household waste from the garbage disposal by the garbage-loading valves 14–17 is completed, the full bore valve 23 is closed and the full front valve 21 and 24 are opened. On the FC section of the discharge pipeline 3 and the section of the trunk pipeline 1 from point C to the waste disposal station 18

a flow of discharged air is created, in which household waste is transported from the garbage disposal with garbage-loading valves 12 and 13. Then, household garbage is transported from the garbage collection with garbage-loading valves located on the discharge pipe 2. When transported from garbage chutes with garbage-loading valves 8 and 11 are closed

air intake valve 27 and full bore valve 21, open air intake valve 26 and full bore valve 20. When transporting from refuse chutes with loading doors, valves 6 and 7

5, the full bore valve 20 is closed and the full bore valve 21 is opened. When clogged, for example, in section EA or section AC of trunk pipeline 1, when transporting household waste from refuse chutes with garbage-loading valves 6 and 7, full-flow valve 21, air intake valve 26 are closed, and air intake valve 22 and full-flow valve 20 are opened. From compacted household waste, there is a pressure differential directed in the opposite direction to the movement, and consequently, in the direction opposite to that in which the compaction and expansion of the household from moves. Because of this, the pressure drop caused by the vacuum pump

0 19, the cork is broken and moves along the section of the main pipeline CA in the direction opposite to the waste disposal station 18 along the outlet pipeline 2 from point A to point B, and further along the section of main pipeline 1 from the point.

5 to station 18 garbage disposal.

Further, in order to eliminate the zaeora, the intake valve 9 and the full bore valves 21 and 24 (all other valves and valves are closed) are opened at the section EB of the discharge pipe 2. In order to eliminate the zaeora in the CD section of the main pipeline and the CF section of the exhaust pipe 3, the intake valve 25 and full gate valves 21 and 23 open (all other valves

5 and valves are closed); and in case of a blockage in the section DE, full bore valves 21 and 23 and an air intake valve 5 are opened (the remaining valves and valves are closed).

Q Thus, when a sieor is formed at any point of the branches and the main pipeline, a pressure drop can be created on the cork made of material, which is directed in the direction opposite to the movement of household waste, ensuring its breaking and moving towards the garbage disposal station.
