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, the method comprising:
- receiving a first material fraction using at least one first input point, the at least one first input point comprising a first feed-in container and a first feed aperture;
- conducting the first material fraction to a channel space of a material conveying channel via the first feed aperture of the at least one first input point and storing the first material fraction temporarily in the channel space or conducting the first material fraction from the channel space to outside of the channel space;
- receiving a second material fraction using at least one second input point, the at least one second input point comprising a second feed-in container and a second feed aperture and temporarily holding the second material fraction in the second feed-in container with a stopper,
- wherein, in a first operating state, said stopper prevents the passage of the second material fraction from the second feed-in container to the channel space of the material conveying channel, and
- wherein the first input point with the first feed-in aperture and the first feed-in container and the second input point with the second feed-in aperture and the second feed-in container are disposed in proximity to each other, in a vertical direction one on top of the other.
An apparatus for feeding and conveying material in a sorted manner in a pneumatic material conveying system, the apparatus comprising:
- a material conveying channel comprising a channel space and a delivery end, wherein the material conveying channel is configured to selectively convey a first material fraction and a second material fraction to the delivery end;
- a first input point comprising a first feed-in container and a first feed aperture to the channel space, wherein the first feed-in container defines a first passageway, wherein the first passageway is open, and wherein the first input point is configured to receive the first material fraction;
- and
- a second input point comprising a second feed-in container and a second feed aperture to the channel space, wherein the second input point is configured to receive the second material fraction,
- wherein second input point further comprises a stopper,
- wherein, in a first operating state, the stopper is configured to prevent the passage of the second material fraction from the second feed-in container to the channel space of the material conveying channel and the second feed-in container a temporary storage for the second fraction material,
- wherein, in a second operating state, the stopper is configured to release the second material fraction to pass from the second feed-in container to the channel space of the material conveying channel,
- wherein a channel part of the material conveying channel is provided with means for temporarily storing material fed into the channel space and with guide means for conducting material to the outside of the channel space, and
- wherein the first input point with the first feed-in aperture and the first feed-in container and the second input point with the second feed-in aperture and the second feed-in container are disposed in proximity to each other, and in a vertical direction one on top of the other.
