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.

Methods and system for waste collection and transport systems are provided. Systems of the present disclosure comprise a loading station providing a point of ingress and storage for materials into a larger system. The chute may temporarily house materials. Venting features are provided wherein the chute or load station is provided in fluid communication with an additional component of the system or an exterior environment.

In a method for guiding and/or instructing in a feed-in station of a material conveying system, the feed-in station includes at least one first input point and at least one second input point, which input points each include at least one input aperture and a shut-off part of the input aperture, which shut-off part is movable between a first position in which the input aperture is at least partly closed, in which case material is not intended to be fed from the input aperture to inside the input point, and a second position in which the input aperture is open, in which second position material can be fed from the input aperture to inside the input point. The first input point and/or the second input point is adapted to include an indicator and/or signal, with which in the method a user is guided and/or instructed to feed in material from the input aperture of the second input point of the feed-in station, when the first input point is in a state in which it cannot receive material. An input point arrangement is used in the method.

Method for feeding in and for handling waste material in the channel section of a pneumatic wastes conveying system, in which method waste material or recycleable material is fed into a feed-in container from the input aperture of an input point of a pneumatic pipe transport system for material and onwards into the channel section between the feed-in container and the material conveying pipe, from where the material is conveyed along with the transporting air via the material conveying pipe to the delivery end of the pneumatic material conveying system, where the material is separated from the transporting air. In the method the material is acted upon by the combined effect of suction and replacement air in the channel section by bringing about compression in size in at least a part of the material being conveyed, by means of an impediment arranged between the conveying pipe and the material to be handled, or against the impediment, before transportation of the material to the delivery end of the pneumatic transport system for wastes.

Method for conveying and handling waste material in the channel section of a pneumatic wastes conveying system, in which method solid waste material or recycleable material fed into a conveying pipe is conveyed in the conveying pipe of the pneumatic pipe transport system for material along with the transporting air flow to the delivery end of the material conveying system, where the material is separated from the transporting air. In the method the material is acted upon in the conveying pipe by stopping the speed of movement of the material being conveyed in the conveying pipe by means of a stopper arranged between the separating device of the delivery end and the material being handled, or against the stopper at, or in the proximity of, the delivery end of the material conveying system and by bringing about in the channel space of the conveying pipe volumetric compression in at least a part of the material being conveyed by means of the stopper arranged between the separating device of the delivery end and the material being handled, or against the stopper, by means of a pressure difference acting on the different sides of the material being handled, such as by the combined effect of suction and replacement air, before transportation of the material onwards in the conveying pipe into a container of the separating device arranged at the delivery end of the pneumatic transport system for wastes.

Method for compensating a change in volume caused by a pressure difference of the intermediate container of an input point of a pneumatic pipe collection system for material and/or for preventing undesired material displacement from the intermediate container. In the method a bypass channel is arranged in the channel section formed by the intermediate container of an input point for compensating a change in volume resulting from the pressure difference of the pressures of different magnitudes possibly acting on different sides of the material and/or for preventing undesired material displacement from the channel section into the material conveying pipe. The invention also relates to an apparatus and to a wastes conveying system.

A method and system for conveying material in a pneumatic material conveying system includes a material input point, a material conveying pipe connectable with a feed-in container, the system being configured to provide a pressure difference in the material conveying pipe that includes a partial-vacuum generator, and a separator device in which the transported material is separated from the transport air at an outlet end of the material conveying system. The material is conveyed in a first stage from the input point to a conveying pipe, into a container space of an intermediate container arranged between the input point and the separator device by a suction/pressure difference provided by the partial vacuum generator in a first time period, and the material conveyed into the container space of the intermediate container is conveyed by a suction/pressure difference provided by the partial-vacuum generator to the separator device.

In an assembly for controlling filtering of vacuum air flow evacuated from a system storage container through an air evacuation duct in vacuum operated waste collection systems, an assembly housing is installed stationary in the air evacuation duct with an inner passage in the assembly housing communicating with the air evacuation duct, a control unit is installed in the assembly housing with a shiftable member intersecting the inner passage in the housing, whereby the shiftable member has one or more air filtering elements and the air filtering element being movable in a direction generally transversal to the inner passage in the assembly housing.

An apparatus for processing material in connection with a pneumatic material conveying system includes a waste container/separating device, into which material is configured to be conducted from a conveying pipe of the pneumatic material conveying system via an inlet aperture and which is configured to be connected to means for achieving a partial vacuum.
