Definitions

  • This technology generally concerns waste inlets that are intended for allowing the insertion of waste therein and for communicating with waste collection systems for the purpose of collecting waste therein.
  • Waste inlets in the form of so called free-standing inlets have for decades been used for the collection of waste, such as residual waste, waste for recycling and organic waste etc.
  • Such free-standing inlets have been used both for installations outside as well as inside buildings and may be combined with any type of temporary storage solution, such as a tank, a container or a section of a transport pipe system of a vacuum waste collection system.
  • the technology generally relates to a vacuum waste collection system for transporting waste of various kinds from insertion points to storage facilities.
  • inlet units for connection to such a vacuum waste collection system and having an outer cover supporting at least one opening waste inlet door allowing access for users to an inlet inner volume that connects downwardly to a waste collection system temporary storage utility.
  • the inlet unit includes a control valve adjustable between closed and open positions. In the closed position the control valve thereby blocks objects introduced into the inlet from entering the waste collection system temporary storage utility and in the open condition it allows introduced objects to fall into the storage utility.
  • an improved method of operating the inlet unit of the present technology wherein, in a basic configuration, a user is first verified as being registered to allow access to the inlet unit inner volume. Then the control valve is closed and its closed state is verified. Such verification releases a commercial inlet door lock and the commercial door is opened, whereupon a discharge valve downstream of the waste collection system temporary storage utility is blocked. Then waste is deposited in the inlet and the inlet door is closed. Finally the closed state of the inlet door is verified and upon verification the control valve is opened so that the inlet unit is ready for a new introduction sequence.
  • the present technology will now be explained with reference to exemplifying embodiments of this technology that are illustrated in the accompanying drawing figures 1-7 .
  • the illustrated embodiment relates to an application of the proposed technology to inlets configured as combined commercial and household inlets that are designed to be integrated in a vacuum controlled waste collection system. It is emphasized though, that the illustrations are for the sole purpose of describing preferred embodiments of the technology and are not intended to limit the presently proposed technology to details or to any specific field of application thereof. The presently proposed solutions may with only minor adaption be applied to most types of inlet configurations and waste handling and transport systems.
  • FIG. 1A The first embodiment of the inlet unit 1 ( Fig. 1A ) is in particular intended for receiving residual waste
  • the second embodiment of the inlet unit 1' Fig. 1B
  • They may both be installed in connection with just about any type of storage utility SU (not specifically illustrated) and may also be used for installations indoors.
  • the inlet unit 1 illustrated in Fig. 1A basically has an outer cover 2 consisting of a top cover 2A, side covers 2B, 2C and two ventilation sections 2D (only one visible in Fig. 1A ) for ventilating the inner inlet unit volume V.
  • the cover 2 supports at least one opening waste inlet door 3; 4 for allowing access for a user to the inlet unit inner volume V.
  • the inlet unit 1 has what may be called a combo-door, 3, 4, namely one large door 3 named a commercial door 3 for receiving business/institution waste of larger volume and one household inlet door 4 for receiving household waste of lesser volume.
  • waste bags having a volume up to 120 liters may be deposited through the commercial inlet door 3.
  • This commercial door is mainly intended to be used by businesses, such as shops, restaurants etc., and institutions, such as schools.
  • In the large door is supported a smaller household door 4 where smaller waste bags having a volume of up to approximately 30 liters may be deposited.
  • the inlet unit 1 and its inner volume V connects downwardly to a waste collection system temporary storage utility SU.
  • This storage utility is not specifically illustrated in the drawings but as indicated by the arrow in Fig. 1A it serves to receive waste that exits the inlet unit 1 inner volume V.
  • the communication between this inner volume V and the waste collection system temporary storage utility SU is controlled by a control valve 5 adjustable between closed CP and open OP positions (see Figs. 3A, 3B , 4A-D and 5 ). In the closed position CP the control valve 5 blocks objects introduced into the inlet unit 1 from entering the waste collection system temporary storage utility SU and in the open condition OC it allows introduced objects to fall into the storage utility SU.
  • the control valve 5 is a flap type valve that may also be named a "beak valve”. It has two pivotal flaps 5A, 5B and additionally serves as a volume limiter for objects that may be allowed to exit the inlet unit towards the temporary storage utility SU. In effect, the theoretical maximum size O max of objects that may pass the control valve in its closed condition OC is very small, as will be seen in Fig. 5 .
  • the two flaps 5A, 5B in the lower part of the inlet unit are each controlled by a separate compressed air cylinder 7A, 7B, all supported by a valve frame 6.
  • Each flap cylinder 7A, 7B has an integrated brake mechanism and their open and closed positions OP and CP, respectively are illustrated in detail in the above mentioned Figs. 3A, 3B , 4A-D and 5 .
  • control valve has two main functions, namely as a safety stop blocking the bottom part of the inlet unit 1 to prevent people falling down into the vacuum waste collection system, and as a volume limiter preventing users from depositing more than 120 liters of waste for each commercial door 3 opening sequence.
  • the commercial door 3 cannot be opened unless the control valve 5 is closed, thereby effectively preventing someone from falling down through the inlet unit 1.
  • the discharge valve of the storage utility may not be opened unless the control valve 5 is closed.
  • the control valve 5 is only activated for the large commercial door 3 but not for the smaller household door 4.
  • the inlet unit is equipped with a control system including an authorization control that preferably involves a user identification reader 15, such as an RFID-reader. This means that access to the inlet unit 1 is only allowed to registered users having the correct RFID-tag. This applies both to the commercial 3 and to the household 4 door.
  • the control system includes a registered user register, first and second sensors D1, D2 for each of the two control valve 5 flaps 5A, 5B, indicating an open or closed control valve 5 state, an electrically controlled door lock (not specifically illustrated), and a third sensor indicating an opened or closed commercial inlet door 3.
  • the control system may further include a fourth sensor D4 registering each waste deposit and being connected to a superior user debiting system.
  • step S the control system checks the authority of the user against a registered user register, and if the user is authorized and registered as a commercial user the brakes of the control valve 5 cylinders 7A, 7B are released and the control valve closes in step S2.
  • step S3 the system verifies that the control valve 5 has closed.
  • the closed CP control valve 5 position is checked by one sensor D1, D2, preferably an inductive sensor, for each flap 5A, 5B.
  • step S4 the flap cylinder brakes are re-applied and the control system then releases the lock of the commercial door 3 and the user in step S5 manually opens the commercial door 3 when the cylinders 7A, 7B have been re-applied.
  • the discharge valve downstream of the storage utility SU is blocked in step S6 when the commercial door 3 is open.
  • the open state of the commercial door is sensed by the system through the door lock, electrical lock, and a third sensor that detects a lever arm of the commercial door 3.
  • step S7 the user then deposits his waste and subsequently closes the commercial door 3 in step S8.
  • the door may be fully or partly self-closing.
  • step S9 the system verifies that the commercial door 3 is closed, again through the door lock, electrical lock, and the third sensor.
  • the brakes of the control valve 5 cylinders 7A, 7B are released and the control valve 5 opens in step S10. This causes waste in the inlet unit 1 volume V to fall down into the storage utility SU and the system and inlet unit 1 are ready for the next sequence/user.
  • invoicing data is sent to a superior user debiting system based on the waste deposit detection made by a fourth sensor D4.
  • one of two optional reference panels 30; 40, Fig. 6A and Fig. 6B , respectively, is positioned above the commercial inlet door 3.
  • the reference panel 30; 40 has three ( Fig. 6A ) or four ( Fig. 6B ), LED's.
  • the inlet unit with a reference panel 30 having three LED's has the following function:
  • the inlet unit having a reference panel 40 with four LED's 41-44 has the following function:
  • Such debiting control based on deposited waste introduced through the household door 4 by a registered household user may likewise be performed, whereby the household door 4 has integrated therein a volume limiter (not specifically indicated) preventing a user from depositing more than approximately 30 liters of waste for each door 4 opening.
  • this debiting sequence functions so that the household user holds his RFID-tag close to the RFID reader 15 on the inlet unit 1.
  • the system checks the authority of the household user and releases a household door 4 lock if the user is authorized and registered as a household user. With the household door 4 lock released the user can manually open the household door 4 and deposits his waste.
  • the user then initiates closing of the household door 4 and just before the waste falls down through the inlet unit 1 to the storage utility SU the door 4 passes a position where a further sensor, inductive sensor, detects that the household door 4 integrated volume limiter is close to a position where the waste falls down.
  • a signal is then sent to the superior user debiting system as a base for user invoicing.
  • a fourth LED 44 on a reference panel 40 is lit to signal to the user that he will be debited for the deposit.
  • the user has two options, namely either to continue the door closing movement to close the door 4 that automatically will be locked by the electric lock, or the user stops the closing movement of the door 4 and initiates a new opening sequence, now with the volume limiter empty. At this stage a next waste volume may be deposited and the sequence continues like before.
