Abstract
An improved method and the related system for pneumatically transporting a powder or granular material placed in an airtight storage container through a transport pipe in high density. In the invention, pressurized gas is being intermittently supplied to the airtight storage container containing the material therein so as to take out of the container and a transport plug is being synchronously fed into the base of the transport pipe, whereby the powder or granular material is successively formed into a long column inside the transport pipe and is pneumatically transported at very slow speed.
Claims9
A high density pneumatic transport method of pneumatically transporting a powder or granular material placed in an airtight storage container to a collector through a transport pipe by the use of pressurized gas, the method comprising the steps of:
- supplying pressurized gas intermittently to the airtight storage container containing a powder or granular material therein so as to take the material out of the container and feed the same into the transport pipe;
- feeding a hollow, elongated transport plug into a base end of the transport pipe in synchronism with the intermittent supply of the pressurized gas so as to section the material, whereby the material is successively formed into a long column in high density and pneumatically transported to the collector at very slow speed;
- and
- finally receiving the material which has been transported in the form of a long column into the collector in the state of substantially gravitational fall.
A high density pneumatic transport system for pneumatically transporting a powder or granular material placed in an airtight storage container to a collector through a transport pipe by the use of pressurized gas, the system comprising:
- an airtight storage container containing a powder or granular material therein;
- a collector adapted to receive the transported material;
- a transport pipe including a horizontal pipe portion, the transport pipe connecting the collector to the airtight storage container;
- a gas supply means for intermittently supplying pressurized gas to the airtight storage container;
- a hollow, elongated transport plug adapted to be fed into a base end of the transport pipe in synchronism with the intermittent supply of the pressurized gas;
- a pipe with a gradually enlarged outlet caliber, the pipe being disposed at the initial end of the horizontal pipe portion;
- and
- a speed reduction means, disposed between the terminal end of the horizontal pipe portion and the collector, for reducing the speed of the material which has been transported in the form of a long column down to substantially gravitational fall.
