Definitions

  • the present invention relates to a device for collecting and compacting waste, in particular a waste container.
  • the present invention relates to a device having the features of the preamble of claim 1.
  • the present invention also relates to a method for collecting and compacting waste.
  • the EP 209 639 A1 a device for compacting kitchen waste.
  • the waste is exposed to atmospheric pressure by sucking out the air with a pump, which compacts it.
  • EP 1 498 364 A1 discloses a device for collecting and disposing of dry waste, wet waste and the like.
  • the device comprises a container with a lid, which is secured by hermetic closure elements, with a piston inside, which can slide and forms a hermetic chamber. Furthermore, there are waste compaction and liquid discharge elements, as well as air and liquid suction elements, which are connected to the chamber and the interior of a flexible container. However, the piston is only retracted by a spring, there is no active pressing of the waste.
  • the WO 2007/076964 A1 discloses a waste container with a bag inside it and a vacuum pump for sucking gas, in particular air, out of the bag, wherein a pressing device is provided with which a material inside the bag can be pressed and thus compressed before the gas is sucked out.
  • a pressing device is provided with which a material inside the bag can be pressed and thus compressed before the gas is sucked out.
  • details of the pressing device are not disclosed, only a pressing plate that moves "downwards" is mentioned.
  • the publication also discloses a welding device for gas-tight sealing of the bag.
  • This method is particularly carried out according to the invention by a device according to the present invention.
  • the invention is based on the realization that it is particularly advantageous to collect and compact waste if the compaction is not only carried out by sucking the air out of the waste bag, but in particular by additional, simultaneous mechanical compression of the waste bag and pressurizing it with compressed air. This leads in a simple way to waste with a particularly small space requirement and thus the best possible use of resources.
  • the device according to the invention for collecting and compacting waste comprises a container for holding a waste bag.
  • Typical containers are known in the prior art and are typically essentially cuboid-shaped or cylindrical.
  • the container comprises an opening, typically the, preferably complete, top, as well as side walls, typically the 4 side walls of the cuboid or the cylinder surface of the cylinder, and a container base.
  • the container is airtight when the opening is closed. This means that if the opening were hermetically sealed, the side walls and the container base or the movable base plate inside the container would form an airtight space.
  • Suitable materials are plastics or metals, in particular glass fiber reinforced plastics, e.g. GRP 30 or GRP 40, PEEK plastics, PA6, as well as stainless steel or aluminum.
  • the container of the device according to the invention also has a first seal at the opening, typically on a surface of the top of the container perpendicular to the side walls (and parallel to the container floor).
  • the seal is at the opening designed all the way around, that is, it encloses the entire opening of the container.
  • This seal is suitable for creating an airtight seal around the opening of a typical waste bag, with appropriate interaction with the second seal on the lid. Suitable sealing materials are known in the art.
  • suitable sealing materials are generally known to those skilled in the art.
  • Typical materials include silicone, silicone foam, EPDM, NBR, CR, cellular rubber, sponge rubber, fluoroelastomers, e.g. Viton ® , fiber seals based on aramid fibers, e.g. KLINGERSIL ® , PTFE (Teflon ® ), polyurethane (Vulkollan ® ), PVC and PMMA.
  • Preferred materials are EPDM and silicone for the first and second seals.
  • Fluoroelastomers, e.g. Viton ® are preferably used as seals against the welding and cutting electrodes.
  • the device has means for fixing a waste bag to the opening of the container, preferably a clamping frame or clamping clamps.
  • a clamping frame is attached to the container by means of a hinge, for example, and encloses the entire opening of the container.
  • the opening is freely accessible so that a waste bag can be placed in the container, with the waste bag coming into contact with the first seal at the opening.
  • the clamping frame or clamps are then closed and are thus able to fix the waste bag to the container.
  • the first seal, with the covering waste bag is not or only partially covered by the means for fixing a waste bag, and remains essentially accessible, in particular for interaction with the second seal of the lid.
  • the first seal is contacted by the means for fixing a waste bag via the waste bag, if this is inserted, and, in the closed position, is also completely between the first seal on the container opening and the second seal of the lid.
  • a clamping frame has the advantage that the waste bag can be placed neatly over the first seal on the container opening when it is inserted and can be fixed to the container using the means for fixing a waste bag, preferably the clamping frame or the clamping clamps. This leads to a high level of tightness when the second seal on the lid comes into contact with the waste bag in the closed position and, if applicable, with the means for fixing a waste bag.
  • the container of the device has a movable base plate inside, which is typically essentially planar.
  • the base plate is designed as a type of piston, which is movable within the container, ie perpendicular to the surface of the base plate, along the side walls, and is arranged so as to be displaceable.
  • the base plate of the container is hermetically sealed from the side walls by means of a third seal.
  • the base plate when the opening is closed, the side walls and the base plate form the airtight interior of the container.
  • the base plate preferably has means which enable the compressed air to be guided towards the top of the base plate.
  • the base plate of the container is not hermetically sealed from the side walls by means of the third seal; rather, when the opening is closed, the side walls and the container floor form the airtight container.
  • the latter embodiment has the advantage that the third seal does not have to be hermetically sealed from the compressed air as soon as it is guided into the interior of the container, which would place higher demands on the material to be used.
  • An inlet opening below the base plate is also sufficient to pressurize the interior of the container with compressed air.
  • the base plate can generally be moved relative to the side walls and, in the closed position of the lid, towards the lid (perpendicular to the surface of the base plate). For this purpose, there are preferably corresponding guide grooves or strips in the side walls.
  • the volume of the container defined by the space into which the waste bag can be inserted, can be reduced.
  • the third seal also referred to as the "seal on the base plate" seals the base plate against the side walls in any position, in one of the embodiments described above, airtight, typically at least to prevent dirt from getting under the base plate.
  • the container When the container is closed, it is thus hermetically sealed by the side walls (these are also airtight) and either by the base plate or at least by the container floor.
  • the container is described as airtight if, with the opening closed, the container maintains an applied negative pressure of 500 mbar (absolute pressure inside) below 800 mbar (absolute pressure inside) for at least 30 minutes.
  • the container has an inlet opening for compressed air, which, controlled by means of an inlet valve, can be supplied with compressed air provided by the means for generating compressed air. Compressed air can thus be introduced into the interior of the container, which is airtight, via the inlet opening. If a waste bag is put over the container opening and filled with the first seal, either via the means for fixing a waste bag or via the second seal of the lid in the closed position, the space between the waste bag and the container is hermetically sealed. Introducing compressed air into the space between the waste bag and the container and with the lid in the closed position thus leads to pressing and thus compacting the contents of the waste bag.
  • the device is configured in such a way that the compressed air, when used for the means for moving the base plate, can also be guided in a controlled manner by means of the inlet valve to the inlet opening, and thus into the interior of the container.
  • the device according to the invention has means for moving the base plate relative to the side walls.
  • These means for moving the base plate are typically suitable for holding the base plate in the position of maximum extension of the volume of the container, and in any case they are suitable for moving the base plate perpendicular to its surface and in the closed position of the lid in the direction of the lid or towards the container opening in such a way that the volume of the container can be reduced.
  • the means for moving the base plate is able to move the base plate towards the container opening, preferably with a pressure force of about 50 kPa to about 1000 kPa, preferably about 100 kPa to about 800 kPa, in particular from about 300 kPa to about 600 kPa.
  • the possible extent of the displacement of the base plate is preferably at least such that the volume of the container, defined by the space into which the waste bag can be inserted, when the opening is closed by the lid, can be reduced by 50%, i.e. to 50% of the maximum extent, preferably by 70%, i.e. to 30% of the maximum extent.
  • Suitable means for displacing the base plate are, for example, screw rods, hydraulic cylinders, for example with air, water or oil as a medium, preferably pneumatic cylinders or bellows.
  • the latter pneumatic cylinders or bellows can advantageously be driven by the compressed air that can be made available by the means for generating compressed air contained in the device according to the invention.
  • the means for displacing preferably comprise return elements, for example spiral springs.
  • the return elements cause or assist a retraction (away from the lid) of the base plate after the waste bag has been mechanically compacted.
  • the restoring forces are typically lower than the compressive forces, preferably from about 50 kPa to about 500 kPa, preferably about 100 kPa to about 300 kPa.
  • the means for moving the base plate is configured in such a way that it can withstand both the compressive force specified above and can also provide the restoring force, i.e. the sum of the two.
  • the device according to the invention further comprises a lid.
  • This is configured to cover the opening of the container and for this purpose has a second seal on the side that interacts with the opening of the container.
  • the lid is configured and arranged in the device in such a way that it can be brought into an open position opposite the opening of the container so that the opening of the container is accessible for inserting a waste bag, and can be brought into a closed position opposite the opening of the container so that the lid interacts with the opening of the container in such a form-fitting manner that a waste bag introduced into the container can be hermetically sealed against the lid between the first seal (at the container opening) and the second seal (on the lid).
  • the second seal thus corresponds in its extension essentially to that of the first seal, i.e.
  • the lid has a suction opening which is arranged on the lid in such a way that, in the closed position, the gaseous atmosphere can be at least partially sucked out from the interior of a waste bag placed in the container by means of the means for generating negative pressure.
  • the lid is configured in such a way that, in the closed position, the waste bag is clamped and sealed between the first seal and the second seal, and optionally the means for fixing a waste bag.
  • the waste bag is thus closed with the lid and the interior of the bag is only in contact with the lid (and the bag itself).
  • the gaseous atmosphere can thus be drawn out of the waste bag through the suction opening on the lid.
  • the negative pressure required for this is provided by the means for generating negative pressure, as defined below.
  • a liquid sensor is preferably provided on the lid next to the suction opening. The latter enables the suction process to be stopped in the event that liquids from the waste bag reach the lid or are sucked out, in order to protect the components of the device from contamination.
  • the device according to the invention further comprises means for generating compressed air.
  • the compressed air that can be generated preferably has at least 1.0 * 10 5 Pa (100 kPa, 1 bar) overpressure, preferably at least 2.0 * 10 5 Pa (200 kPa, 2 bar) overpressure.
  • the compressed air can be used for introducing, via the inlet opening, into the container interior, as well as for the means for moving the base plate, provided that it is an air-operated means, for example pneumatic cylinders or bellows.
  • the device according to the invention also has means for generating negative pressure.
  • Suitable means e.g. vacuum pumps, are known in the art.
  • the negative pressure that can be generated is preferably at least 5.0 * 10 4 Pa (50 kPa, 500 mbar) absolute pressure, preferably at least 2.0 * 10 4 Pa (20 kPa, 200 mbar) absolute pressure.
  • the vacuum pump must therefore be able to generate an absolute pressure of 500 mbar, preferably 200 mbar, in the container interior, and thus in the waste bag.
  • the negative pressure is used to suck the gaseous atmosphere out of the waste bag.
  • the device preferably has suitable means, e.g. a negative pressure hose, to guide the negative pressure to the lid, and in particular to the suction opening on the lid.
  • the means for generating negative pressure preferably comprise a filter, preferably a carbon filter, and/or a liquid sensor.
  • a filter preferably a carbon filter
  • a liquid sensor preferably a liquid sensor
  • the device according to the invention further comprises means for thermally welding a waste bag placed in the container.
  • the means can be located at the opening of the container and/or on the lid.
  • Suitable means for thermally welding plastic bags such as waste bags made of PE (polyethylene), PP (polypropylene) or PLA (polylactide) are known in the art.
  • Thermal welding is understood to be a process in which plastic films are first heated and then pressed together under pressure so that they are permanently connected.
  • Typical means for thermal welding are heating electrodes, in particular strip electrodes, as known in the art and commercially available.
  • an edge band or wire is used.
  • appropriate welding temperatures are used, in the range of 80°C to 140°C, e.g. approx.
  • thermoplastics such as PP and PE, up to 140°C for PLA films.
  • Suitable welding times are from approx. 0.1 to 5 seconds, preferably approx. 0.5 to 3 seconds.
  • the duration of the welding is preferably temperature-controlled; the temperature control is determined, as is known in the art, via the electrical resistance of the edge band or wire. This ensures a duration sufficient for complete, tight welding.
  • Suitable parameters, such as the dimensioning of the edge band or wire and the power supply, for thermally welding plastic films are known in the art.
  • the edge band or wire is preferably coated with a PTFE layer to prevent the plastic film from sticking.
  • the means located at the opening of the container and/or on the lid are arranged such that, when the lid is in the closed position, a waste bag stretched over the opening of the container can be closed and welded to a corresponding part of the bag, for example a folded-over flap of the bag, or a separate part if the flap or the separate part is placed over the opening.
  • the means for thermal welding in particular the strip electrodes, are arranged essentially parallel to the first and second seals, either on the lid and/or on the container opening.
  • the means for thermal welding are preferably arranged all the way around the container opening to ensure complete closure of the waste bag. This can be achieved by means for thermal welding, in particular the strip electrodes, which are arranged on the lid essentially parallel to the second seal, or on the container opening essentially parallel to the first seal, in each case completely circumferentially (around the container opening).
  • the means for thermal welding in particular the strip electrodes, are arranged both partially on the lid essentially parallel to the second seal and partially on the container opening essentially parallel to the first seal, it is sufficient and preferred that the means are arranged together essentially completely circumferentially around the container opening, i.e. together ensure a full circuit. A full circuit is ensured if there is at least a little overlap of the opposite means, i.e.
  • the arrangement of the means for thermal welding, in particular the strip electrodes is preferably within the respective area spanned by the seals.
  • the device according to the invention has means for separating the separate part of a film with which the opening of the container and thus the inserted waste bag is covered.
  • Such means for example a cutting or tearing edge, preferably a cutting electrode, are known in the prior art. The latter are essentially the same electrodes as those used for welding as described above, only the welding time and/or temperature are increased so that the film material is separated.
  • Typical temperatures are about 140°C to about 150°C for a period of about 1.5 to 3 seconds.
  • the device according to the invention is basically suitable for the use of various waste bags; preferably, thermally weldable plastic bags, such as waste bags, made of polyolefins, such as PE (polyethylene) and PP (polypropylene), and made of polyesters, such as PLA (polylactide), are used for the device according to the invention and in the method according to the invention.
  • thermally weldable plastic bags such as waste bags, made of polyolefins, such as PE (polyethylene) and PP (polypropylene), and made of polyesters, such as PLA (polylactide)
  • the device according to the invention further comprises means for perforating a waste bag on the lid.
  • These are typically arranged within the area spanned by the second seal, in particular on the lid, so that the perforation is made possible within the area spanned by the second seal.
  • the means are also typically arranged outside the area spanned by the means for thermal welding.
  • the means for perforating a waste bag creates a defined "outlet opening" on the waste bag, preferably on the cover, i.e. for example a folded-over flap of the bag, or on the separate part.
  • Suitable means for perforating a waste bag are, for example, one or more spikes or cut edges.
  • the means for perforating a waste bag can preferably be used in a controlled manner, i.e. not permanently active, preferably electrically activated. For example, they are one or more electrically extendable spikes or one or more electrically extendable blades, which then retract again. This can be activated before a pressing or suction step. Subsequent withdrawal of the means has the advantage of reducing the risk of injury when changing the waste bag.
  • the means for perforating a waste bag is arranged in the suction opening or perforates through the suction opening.
  • the device according to the invention comprises means for fixing the cover of the waste bag.
  • a corresponding part of the bag for example a folded-over flap of the bag, or a separate part, is placed over the container opening.
  • the device according to the invention comprises means for fixing the cover of the waste bag, typically one or more clamps or tensioning strips. These are preferably positioned on the front of the container, e.g. below the container opening.
  • the means for fixing the cover of the waste bag typically one or more clamps or tensioning strips, interact with spikes for fixing the cover of the waste bag.
  • the latter are, for example, also positioned on the front of the container below the container opening.
  • safety switches are present, for example also on the front of the container, for example below the container opening, which are arranged so that they interact with the cover of the waste bag, e.g. are triggered by contact with it.
  • the safety switches allow you to check whether the waste bag cover has been correctly placed. A sealing or cutting step should only be carried out in the last case.
  • the device according to the invention also has means on the lid for irradiating the interior of the container with UV light (380 to 100 nm), in particular UV-C light (280 to 100 nm). Irradiation of waste with UV light, in particular UV-C light, reduces and inactivates harmful microorganisms, thereby reducing putrefaction and other metabolic processes, and thus reducing odor formation. Suitable lighting means for generating UV light, in particular UV-C light, are known in the art, for example UV LEDs.
  • the lid preferably also comprises a protective device for the means for irradiating the interior of the container, in particular when not in use.
