Abstract
An apparatus and method for feeding and conveying material in a sorted manner in a pneumatic material conveying system, in which at least two material fractions re fed from a feed aperture and conveyed in a channel space further to a delivery end of a material conveying channel by gravity and/or suction Material is fed from at least one feed aperture of at least one input point and a first material fraction is conducted to the channel space and stored temporarily in the channel space or conducted to the outside of the channel space, and material is fed into a feed-in container, in which a second material fraction fed therein is held in temporary storage by a stopper means.
Claims25
A method for feeding and conveying material in a sorted manner in a pneumatic material conveying system, in which method at least two material fractions are fed via at least two input points into a channel space of a material conveying channel from a feed aperture and conveyed in the channel space further to a delivery end of the material conveying channel mainly by means of gravity and/or suction generated by a partial-vacuum generator of the pneumatic material conveying system, wherein material is fed from at least one feed aperture of at least one input point and a first material fraction fed via at least one first input point is conducted to the channel space of the material conveying channeland stored temporarily in the channel space or conducted from the channel space to the outside of the channel space, and material is fed into a feed-in container of at least one second input point, in which feed-in container a second material fraction fed therein is held in temporary storage by a stopper means, which stopper means prevents the passage of the material fraction in a first operating state from the second feed-in container to the channel space of the material conveying channel, and that feed-in containers of a first input point and a second input point are disposed in proximity to each other, in a vertical direction one on top of the other.
(canceled)
An apparatus for feeding and conveying material in a sorted manner in a pneumatic material conveying system, which apparatus comprises at least two input points for feeding at least two material fractions via a feed-in container of the input point into a channel space of a material conveying channel from a feed aperture and conveying them in the channel space further to a delivery end of the material conveying channel mainly by means of gravity and/or suction generated by a partial-vacuum generator of the pneumatic material conveying system, wherein the apparatus comprises at least one feed aperture of the input point and a passageway from the feed aperture of the input point of the feed-in container to the channel space of the material channel from the feed aperture, and that the passageway from the feed-in container of a first input point to the channel space of the material channel is open, and that in connection with at least a second feed-in container and the channel space of the material channel a stopper means is arranged, which stopper means prevents in a first operating state the passage of a material fraction from the second feed-in container to the channel space of the material conveying channel and in a second operating state releases the material fraction to pass from the second feed-in container to the channel space of the material conveying channel, whereby the second feed-in container is arranged to be used as a temporary storage for material in the first position of the stopper means, and that a channel part of the material conveying channel is provided with means for temporarily storing material fed into the channel or with guide means for conducting material to the outside of the channel space, and that feed-in containers of a first input point and a second input point are disposed in proximity to each other, in a vertical direction one on top of the other.
