Definitions

  • the present invention relates to a method of to collecting and managing waste, specifically smaller amounts of waste normally referred to as litter that is introduced in waste or litter bin assemblies.
  • Littering that is the discarding of smaller amounts of loose waste/litter, in streets and public open places is not only an environmental problem but is in many countries even a criminal offence. In urban areas, litter should be dropped in litter bins that are frequently placed in public places. However, emptying of the traditional separate litter bins is a rather time consuming and expensive task.
  • US-A-3,977,729 discloses a refuse receiving system that uses a method of collecting and managing waste according to the preamble of claim 1 that may serve to receive household waste and that may also be used as a waste-paper or litter bin system.
  • the system uses sluice-like waste insertion elements that either alone or in combination with a bottom discharge valve form a space in which inserted waste may be received and from which the collected waste may be emptied into a system transport pipe at selected times and during optional operational phases of the system
  • the collecting space is connected to a system transport pipe but may be disconnected from the transport pipe to secure that system vacuum will not be communicated to waste inlets thereof during waste insertion phases, to thereby reduce noise and minimize injury risk.
  • the invention provides a solution overcoming the above discussed problems experienced with the prior known techniques.
  • the invention provides a method enabling the collecting and managing of smaller amounts of unpackaged waste in waste bin assemblies connected to a refuse vacuum transport system, wherein waste introduced into a waste bin assembly when the refuse vacuum system is active, is held back therein during such an active phase, is emptied therefrom when the system is in a deactivated state to be temporarily stored in a transport pipe of the system and is removed by the refuse vacuum system in connection with the next activation thereof.
  • the waste that has been temporarily stored in the transport pipe is removed therefrom in a separate pre-activation phase immediately preceding the next active phase of the entire system.
  • an interior of said litter bin assemblies is connected to the refuse vacuum transport system through a controlled discharge valve, whereby all assembly discharge valves are maintained in closed position during activation of the vacuum transport system, so that inserted waste is collected in the respective assembly.
  • the discharge valves are then opened during a deactivated phase of the vacuum transport system, to empty the waste bin assemblies and temporarily store the waste in a transport pipe of the system.
  • the stored waste is finally removed from the transport pipe in association with the next active phase of the system.
  • waste and litter refer specifically to such unpackaged waste in the form of paper, wrappings, fruit, fast food leftovers etc. that has traditionally been collected in so called litter bins provided in public places.
  • Fig. 1 is illustrated a very schematic example of a refuse vacuum transport system 1 of the general type that is widely used for collecting larger amounts of primarily domestic/household waste or refuse that is ordinarily packaged in plastic refuse bags.
  • a system 1 comprises a collection central 2 having vacuum generating equipment, such as one or several strong exhausters, filter equipment, silencers and a storage capacity for the collected refuse.
  • the mentioned collection central equipment may be of any standard type used for such systems and will therefore not be specifically described or illustrated herein.
  • refuse is sucked in to the collection central 2 by strong vacuum that is applied to a transport pipe 3 and in the illustrated basic embodiment, drawn with full lines, to the branch or section pipes 13, 23 when the system is in an active phase.
  • Said active phase is entered during daytime and early evening only, since this is the time that refuse is introduced into the system, and not least since nighttime operation would in many places cause unacceptable environmental disturbance, in the form of noise caused e.g. by operating exhausters or the application of a strong vacuum.
  • insertion points generally designated by the reference numeral 5, that may be in the form of refuse chutes extending through a multi-storage building and having an insertion opening associated with each story, or that may be so called "separate" insertion chutes normally being positioned outdoors and having one insertion opening.
  • insertion points generally designated by the reference numeral 5
  • a refuse discharge valve CDV-A and CDV-B not specifically illustrated, that supports the inserted refuse until the respective chutes are emptied in a controlled or preset sequence during the active phase of the system 1.
  • Fig. 1 indicates that the refuse transport system 1 may contain further branch pipes, such as the additional branches/sections 33, 43 drawn with dash-dot lines therein.
  • Said additional branch pipes 33, 43 communicate either directly with the main transport pipe 3 or with another branch pipe, and thereby with the collection central 2, or indirectly therewith through a sectioning valve 40.
  • waste/litter bin assemblies 4 are provided therein. Waste bin assemblies 4 are provided at appropriate positions directly above a transport pipe or branch of the vacuum transport system 1 to allow for a gravity feed of waste W (see figs. 2 and 3) from each waste/litter bin assembly 4 into the respective transport pipe or branch. In the embodiments schematically illustrated in fig. 1 waste bin assemblies 4 are provided in association with the branches 23, 33 and 43.
  • FIG. 2 An exemplary embodiment of an appropriate waste bin assembly 4 associated with the branch 23, is illustrated in figs. 2 and 3.
  • the assembly 4 has an upper insertion structure 9 that is normally positioned above ground G and that consists of an outer housing 11 having at least one insertion opening 10 and partially enclosing an internal collection chamber 12 (fig. 2).
  • a lower portion of the waste bin assembly 4 is here received in a service chamber 6 positioned below ground G.
  • a front wall of the service chamber 6 has been removed so as to illustrate, at least partially, some of the vital elements received therein.
  • This lower portion mainly consists of a discharge valve WDV and connecting members, not specifically designated, for connecting the upper structure 9, and specifically its collection chamber 12, to the inlet of the valve WDV and for connecting the valve outlet to a transport pipe branch 23 of the system 1 through a branching 7 attached thereto.
  • the internal collection chamber 12 of each waste bin assembly 4 is connected to a transport pipe/branch.
  • the waste discharge valve WDV is to close off the bottom of the internal collection chamber 12 when the valve WDV is in its closed position. In most cases it is also preferred that the valve completely seals off the internal collection chamber 12 from the transport pipe/branch pipe of the system, so that practically no vacuum may be applied to said collection chamber when the valve is closed.
  • the discharge valve WDV is a simple and inexpensive flap type valve where the flap 15 is controlled by a fluid cylinder to which fluid is supplied through supply lines 8A that outside the service chamber run in protective tubes 8 extending along the branch pipe 23. Said protective tubes 8 may furthermore or alternatively, depending upon the actual method used for controlling the valves, receive electric lines or fluid control lines. In the closed position (fig.
  • figs. 4A and 4B are schematically illustrated in figs. 4A and 4B and will now be briefly explained.
  • fig. 4A is illustrated the 24 hour operation of a relatively large system for which it-is justified to maintain the-system in an active phase, with its exhausters operating and applying vacuum to the transport pipes/branches, during the full day. The system is deactivated during late evening, night and early morning when practically no refuse is inserted into the chutes.
  • chutes are emptied in a specific sequence that may vary from system to system and that is only exemplified by the shown regular sequence.
  • the different chutes 5, or branches 13, 23, 43 are emptied by opening the corresponding chute discharge valves CDV-A, CDV-B and CDV-C, respectively, and, where applicable, the corresponding sectioning valve 40.
  • the assembly discharge valves WDV of all waste bin assemblies are closed during the entire active phase of the system 1 as well as during a later described pre-active phase of the system.
  • the assembly discharge valves WDV may on the other hand be open during the entire non-active phase of the system 1 or during only a restricted time, shortly before the pre-active phase of the system 1.
  • Loose waste/litter W (figs. 2 and 3) that is introduced into the waste bin assemblies 4 when the assembly discharge valves WDV are closed, is collected in the internal collection chambers 12 thereof, supported on the flap 15 of the assembly discharge valves WDV (fig. 4A-B).
  • waste W from the collection chambers 12 of the waste bin assemblies 4 is emptied into a corresponding transport pipe/branch pipe 23, 33, 43, of the system 1, thereby allowing waste emptied from the assemblies to be temporarily stored in said pipe 23, 33, 43.
  • Closing of the discharge valve WDV of each waste bin assembly 4 again is then performed prior to commencing the next pre-active and active phases of the vacuum transport system.
  • the temporarily stored waste W is removed from the pipes 23, 33, 43 in association with said next active phase of the refuse vacuum transport system 1.
  • Waste/litter W temporarily stored in transport pipes/branch pipes 23, 33, 43 of the refuse vacuum transport system 1 is removed therefrom in a separate pre-active phase immediately preceding the active phase of the system 1 and by the full system vacuum.
  • This will secure a safe and effective transport of the loose waste/litter to the collection central 2 and will still only insignificantly add to the active phase of the system.
  • the temporarily stored waste/litter W is removed simultaneously from all pipes 23, 33 and 43, in order to keep the pre-active phase very short. Specifically, this means that to perform efficient removal of all said waste/litter W the exhausters will only have to be started shortly before the actual active phase, with the resulting saving in time and energy.
  • the invention also covers embodiments for very large systems, where stored waste/litter W from different groups of waste bin assemblies 4 is removed in separate consecutive steps, such as for one or more of the different groups of bin assemblies or for one or more branches/sections of the system.
  • fig. 4B is illustrated the 24 hour operation of a smaller system for which it is not necessary to maintain the system in an active phase, with its exhausters operating and applying vacuum to the transport pipes/branches, during a full day. Therefore, in such a smaller system, several active phases, in the example two, are entered during the day, separated by a further non-active phase.
  • the application of the method of the invention to this system is similar to that of the larger system, the assembly discharge valves WDV may be opened during each non-active phase and the pre-active phase is entered immediately before each active phase.
  • fig. 4B also indicates that a weak suction may applied to some or all of the transport pipes/branches 23, 33, 43 before a pre-active phase to provide a forced emptying supporting the gravity feed to secure discharge of all waste W from the internal collection chambers 12 of the litter bin assemblies 4 to the transport pipes/branches 23, 33, 43.
  • This forced emptying is preferably performed by means of a separate exhauster creating a relatively weak vacuum in the transport pipes/branches 23, 33, 43 before the pre-active phase.
  • said forced emptying is likewise preferably performed in one step for all waste bin assemblies 4 in all branches/sections, but it may likewise, depending upon the size of the system, be performed in separate consecutive steps, such as for one or more of the different groups of bin assemblies or for one or more branches/sections of the system.
  • the application of such a weak vacuum will not cause any significant noise and will not involve any danger of injuries at the insertion openings.
  • waste bin assemblies 4 may be arranged in specific waste bin branches 33 or may be positioned in branches 23, 43 that also contain refuse chutes 5 (see fig. 1). In the branches 23, 33, 43, the waste bin assemblies 4 may also be grouped in groups of different numbers or may be positioned individually. The invention therefore covers all such combinations.
