Abstract

Dust collection vehicle, relates to transport equipment using an air cushion for picking up and transporting dust-forming bulk materials in terrain impassable by land, for example, in quarries after blasting. The dust collecting vehicle comprises a housing, a loading tank with an air duct and suction nozzles of the dust-air mixture. In order to lift bulk material from the surface of the soil, the vehicle is equipped with a agitator. The agitator contains injection nozzles located around the perimeter of the exhaust pipe, and a gap under the flexible skirt. The loading tank is looped and mounted around the suction pipe of the air stream. The discharge nozzles of the exhaust pipe and the suction nozzles of the dust-air mixture are made towards each other. The technical result is to ensure stable operation and expand the scope of use of the vehicle for collecting dust-forming bulk material from the soil surface, which is an additional valuable raw material for industrial enterprises. 1 ill.

Description

Dust collection vehicle, relates to transport equipment using an air cushion for picking up and transporting dust-forming bulk materials in terrain impassable by land, for example, in quarries after blasting.

A vehicle is known for pneumatic loading of bulk material, comprising a housing, a loading container with an air duct and a suction nozzle of the dust-air mixture, a nozzle around the perimeter of the exhaust pipe, agitator and air drive. (RF patent №2058256. Suction pneumatic installation for loading and unloading bulk materials, publ. 04/20/1996)

A known vehicle is not adapted for tedding dust on the surface of the soil and its capture.

Known vehicles containing a housing, loading capacity, duct, discharge nozzles around the perimeter of the exhaust pipe, agitator, flexible skirt and air blower. (US patent No. 5444440. Hovercraft, publ. 10/03/1995, RF patent No. 87398. Hovercraft, publ. 10/10/2009, RF patent No. 2,144,481. Amphibious hovercraft, publ. 03/27/2001 , RF patent No. 2256568. Air cushion apparatus and flexible fence for it, publ. 10/17/2003, RF patent No. 232,390. Amphibious hovercraft, publ. 10.07.2008).

Mentioned vehicles are not equipped with dust collecting devices for bulk materials from the surface of the soil, for example, in quarry conditions, after blasting, excavation process.

A dust collecting vehicle is also known, comprising a loading container with an air duct and suction nozzles of the dust / air mixture, an air blower, an air intake pipe, discharge nozzles around the perimeter of the exhaust pipe, agitator and flexible skirt. (Dust formation and solutions for dust collection in quarries. Davydov S.Ya., Boyarsky G.A., Belov S.V., Cheremisina T.N. Mining informational and analytical bulletin. No. 3/2016)

In this device, which has an advantage over the above, has uneven load distribution from the loading capacity, which is reflected in the steady progress on uneven soil surface, especially in career conditions.

The objective of this development is to ensure its stable operation while expanding the field of use of the vehicle for collecting dust-forming bulk material from the soil surface, which is an additional valuable raw material for industrial enterprises.

The problem is achieved in that in a vehicle for dust collection, containing a loading container with an air duct and suction nozzles of the dust-air mixture, an air blower, an intake pipe of the air flow, discharge nozzles around the perimeter of the exhaust pipe, a agitator and a flexible skirt, the loading container is looped and mounted around the suction pipe of the air flow, and the agitator is made in the form of discharge nozzles located along the perimeter of the exhaust pipe, and the clearance d flexible skirt, the discharge nozzle of the exhaust pipe and suction nozzle are made dust-air mixture toward each other.

The figure shows a diagram of a vehicle for dust collection.

The vehicle for dust collection contains, mounted on the housing 1, a loading container 2 with an air duct 3 and a pipe 4 with suction nozzles 5 for dust-air mixture. Along the perimeter of the exhaust pipe 6, discharge annular nozzles are mounted. The loading tank 2 is looped and mounted around the suction pipe 7 of the air flow.

Using the air blower 8 create a calculated excess pressure. The air cushion between the flexible skirt 9 and the flat bottom 10 is created by a stream of air from the annular nozzles of the exhaust pipe 6. By the flow of compressed air from the nozzles of the exhaust pipe 6, tedding, knocking and lifting of dust particles of material from uneven surfaces of the soil surface 11. When pumping air by an air drive 8 a vacuum is created in the air intake 7. Raised dust particles are sucked in by air flows with nozzles 5 into the looped pipe 4 and sent through the air duct 3 to the hopper 2. After cleaning the filter 12 from dust particles, the air is sucked into the air intake 7. In the air intake 7, the purified air is mixed with atmospheric air, from where the air drive 8 is pumped through the discharge nozzles into the cavity 13 of the air cushion.
