Abstract:
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 (10) from the input aperture (2) of at least two input points (1) of a pneumatic pipe transport system for material and onwards into the channel section (20, 21, 22) between the feed-in container and the material conveying pipe (100), from where the material is conveyed along with the transporting air via the material conveying pipe (100) to the delivery end of the pneumatic material conveying system, where the material is separated from the transporting air. In the method the channel section (20(II), 20(III), 20(IV) . . . (22(II), (22(III), 22(IV)) of at least one second input point is connected to the channel section (20(I), 21(I), 22(I)) of one first input point between the input point (1) and an impeding means (30, 30′), in that in the method at least a part of the material (w1, w2, w3, w4) fed in is acted upon by the combined effect of suction and replacement air in the channel section (20(I), 21(I), 22(I) . . . (20(IV), 21(IV), 22(IV)) by bringing about compression in size in at least a part of the material (w1, w2, w3, w4) being conveyed, by means of an impediment (30) arranged between the conveying pipe (100) and the material (w1, w2, w3, w4) to be handled, or against the impediment, before transportation of the material to the delivery end of the pneumatic transport system for wastes.
Abstract:
Method for handling material in a pneumatic pipe transport system, in which material, such as waste material, is input from an input aperture of an input point (3), such as from the input aperture of a refuse chute or of some other input point, and is conducted along a feeder channel (2) with a shaper device (1) arranged in connection with the input point or in the proximity of it, in which case the material to be handled is conducted into the shaper device and/or through it by the aid of at least partly gravity and/or the suction and/or a pressure difference of the pneumatic pipe transport system. In the method the material is handled with one handling means (10) in a shaper device (1), which handling means is rotated around an axis of rotation when handling material and which handling means comprises an aperture (20), which is arranged eccentrically with respect to the axis of rotation of the handling means, that the rotatable handling means (10) arranges the material to be infed into the proximity of the output aperture and, if necessary, shapes the material, together with at least an edge (18) of the output aperture of the rotary shaper and/or the wall of the output channel (4), when the handling means (10) is rotated with a drive device (7).
Abstract:
The present disclosure relates generally to the field of waste collection, and particularly to techniques for requesting and controlling access to a waste collection point by using a mobile user device. The mobile user device is initially provided with a user ID that is granted permanent or temporary access rights to one or more hatches of one or more waste containers of the waste collection point. By using the user ID and a user input that comprises an indication of one or more of the waste containers to be accessed in the waste collection point at a given time instant, the mobile user device sends an access request to an access control system. In response to the access request, the access control system unlocks or opens the hatch(es) of the waste container(s) to be accessed, when the mobile user device is in the vicinity of the waste collection point. By so doing, it is possible to provide efficient access management for the waste collection point.
Abstract:
A method for conveying material in a pneumatic material conveying system, such as a waste conveying system, which material conveying system comprises at least one material, specifically waste material, input point (60), a material conveying pipe (100) which is connectable into medium communication with a feed-in container of the input point (60), means for providing a pressure difference and/or transport air flow in the material conveying pipe at least for the time of transport of the material, which means for providing the pressure difference and/or transport air flow comprise at least one partial-vacuum generator (125A, 125B), and which material conveying system further comprises at least one separator device (90A, 90B), in which the transported material is separated from the transport air at an outlet end of the material conveying system. In the method the material is conveyed in a first stage from the input point (60) to a conveying pipe (100, 100A, 100B, 100C, 100D, 100E), into at least one container space (202, 202A, 202B) of an intermediate container (200, 200A, 200B) arranged between the input point (60) and the separator device (90A, 90B) by means of suction/pressure difference and/or transport air flow provided by the at least one partial vacuum generator (125A, 125B) in a first time period (t1), and that in a second stage of the method the material conveyed in the previous stage into the at least one container space (202, 202A, 202B) of the intermediate container (200, 200A, 200B) is conveyed by means of suction/pressure difference and/or transport air flow provided by the at least one partial-vacuum generator (125A, 125B) to the separator device (90A, 90B) in a second time period (t2). The invention also relates to a system.
Abstract:
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.

Abstract:
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.

Abstract:
Method for filling a waste container/separating device (50) of a pneumatic material conveying system, in which method material is conducted into a material container from a conveying pipe (100) via an inlet aperture (55) and in which method, for bringing about the suction/partial vacuum needed in conveying the material, the suction side of a partial-vacuum source (30) is connected to act in the container space of the waste container/separating device (50) and onwards into the conveying pipe (100). By changing the point at which the suction of the partial-vacuum source acts or the strength of its action in the container space (68) of the waste container/separating device (50), the input direction in the container space of the material (W) being conducted into the container space from the inlet aperture (55) is acted upon.
