Definitions
- the invention relates to devices for the production of mail, in particular for composting garden and kitchen waste.
- Known devices of this type usually consist of single-shell containers with an essentially cylindrical or square cross-section, in the container walls of which openings are provided through which oxygen is to be supplied to the material to be composted and at the same time the water vapor produced during the composting process is to be removed to prevent putrefaction and unpleasant smells.
- This is usually only possible in an imperfect manner because the waste to be composted clumps and lies so tightly against the inside of the container walls that the necessary ventilation is impossible.
- DE 30 19 253 A1 discloses a double-layer composting device with a closed, cylindrical outer jacket provided with thin vertical webs pointing inwards and with a cylindrical inner jacket arranged as a wire mesh and spaced from the outer jacket at a distance of 2 to 5 cm , in which the filling opening provided at the upper end of the two coats for the material to be composted is covered with a flexible cover film and the compost can only be removed after the two coats have been removed.
- a device for the production of compost is known with an essentially pyramid-shaped ventable container on the top, which has an upper filler opening, which can be closed by a lid, for the material to be composted, a lower one a flap closable removal opening for the compost and several lower ventilation openings passing through the container wall.
- an upper filler opening which can be closed by a lid, for the material to be composted
- a lower one a flap closable removal opening for the compost
- several lower ventilation openings passing through the container wall Provided on the inside of the container wall by thin, vertical webs projecting laterally from it, wide vertical and vertically merging flow channels open to the inside of the container for the air entering through the ventilation openings and passing along the inside of the container wall.
- the object of the invention is to eliminate these disadvantages and to provide a composting device in which the ventilation avoids cooling and drying out of the material to be composted as possible despite the necessary supply of oxygen.
- a device for producing compost with a container, which preferably tapers upwards and can be vented at the top, with an upper filling opening for the material to be composted, which can preferably be closed by a lid, a lower, preferably by a flap closable removal opening for the compost, several lower ventilation openings passing through the container wall and with several air guiding elements arranged on the inside of the container wall for the supply air entering through the ventilation openings and flowing along the inside of the container wall solves that a flow labyrinth formed by the air guide elements and braking the air flow along the container wall is provided on the inside of the container wall.
- This configuration achieves a very low flow velocity of the supply air entering through the ventilation openings along the inside of the container wall, combined with intensive washing of the material to be composted, so that the amount of air flowing through the container is suitable for the release of oxygen the material to be composted and the absorption of water vapor from the material to be composted are used more intensively, so that only a much smaller amount of air flowing through the container is required for proper composting.
- the reduction in the flow velocity of the air and the reduction in the amount of air required also reduce the heat removal from the material to be composted by the air flowing through the container.
- the air guiding elements forming the flow labyrinth represent spacers for the material to be composted, as a result of which the container wall provided on the inside with the flow labyrinth according to the invention receives good thermal insulation.
- the air guiding elements are arranged one above the other in hen are arranged, wherein an air guide element of the next row is arranged as a baffle above a short flow channel formed between two adjacent air guide elements of a row.
- elevations projecting from the inside of the container wall into the interior of the container and / or flow bodies resting on the inside of the container wall are provided as air guiding elements forming the flow labyrinth.
- this design also enables the double-walled design of the container walls.
- a two-shell design of the container walls can comprise, for example, an outer shell with a smooth inner wall and a thin-walled inner shell which bears against it and contains the flow body forming the flow labyrinth and which is connected to the outer shell by adhesive or snap connections.
- the air guiding elements are designed as short, elongated ribs arranged in oblique and / or horizontal rows.
- the elevations projecting from the inside of the container wall into the interior of the container are provided with edges that at least partially cover the flow channels.
- FIG. 1 shows a side view of a compost bin
- FIG. 2 shows a section through a first embodiment of a compost bin, with a labyrinth of flow that brakes the air flow on the inside of its side walls
- FIG. 3 shows a section through a compost bin container with a further embodiment of the flow labyrinth on the inside of its side walls
- FIG. 4 a view of a section of a container side wall with a further embodiment of the flow labyrinth
- FIG. 5 a section along the line BB in FIG. 4
- FIG 6 shows the detail D of FIG. 4 in an enlarged view
- FIG. 7 shows a section along the line CC in FIG. 6.
- the device according to the invention for the production of compost has a container 1 which is open at the bottom and is square or circular in plan, which tapers upwards and at the upper end has a horizontal ceiling 2 with a filling opening 4 which can be closed by a cover 3 Good to be composted and in its side wall 5 has a lower removal opening 7 for the compost which can be closed by a flap 6.
- a container wall 5 near its lower edge 8 there are several round or oval ventilation openings 9, which are distributed along this edge and pass through the container wall 5.
- Air guiding elements 10 are provided on the inside of the container wall 5, which form a flow labyrinth that brakes the air flow for the supply air entering through the ventilation openings 9 and flowing along the inside of the container wall 5.
- the air guiding elements 10 are arranged at a distance from one another, in superimposed, horizontal or oblique rows, wherein a short, essentially vertical flow channel 11, which is delimited laterally by the air guiding elements 10, is formed between two adjacent air guiding elements 10 of a row An air guide element 10 of the next row is arranged above its upper end, which acts as an impact body for the air flowing upward in the flow channel 11.
- the air guide elements 10 is formed as short, elongated ribs 12 projecting inwards from the container wall 5 and extending obliquely to the horizontal, which ribs in each of the rows one above the other are offset from the ribs 12 of the adjacent rows.
- the arrangement of the ribs 12 is shown only schematically in FIG.
- the length, width and height of the ribs 12 as well as the distances between the individual ribs 12 of a row and also the distances between the rows determine the size and the course of the short flow channels 11 in the individual rows.
- the respectively desired braking effect of the flow labyrinth can be determined by the suitable selection of these dimensions.
- the air guiding elements 10 are designed as scale-like elevations 13 which project inwards from the container wall 5 and which are arranged in roof-like rows in rows one above the other.
- two mutually adjacent elevations 13 delimit an essentially vertically extending flow channel 14, above the upper end of which an elevation 13 of the next row is provided as a baffle for the air flowing through the flow channel 14.
- the elevations 15 provided with the laterally protruding plates 16 are in one another overlapping rows staggered net, so that in each case the flow channel 11 delimited by two adjacent elevations 15 opens upward in a row directly into the underside of the undercut flow channel 18, which runs along the lateral boundary of the raised elevation 15 of the row above it.
- the partial roofing of the flow channels 11, 18 represents reliable protection of these flow channels against laying by small parts of the composting material, even if the composting material in the container 1 during the composting process sinks from top to bottom.
- the partial roofing of the flow channels or the configuration of the scale-like elevations, which is relatively wide compared to narrow webs, facilitates the sinking of the composting material and its compaction during the composting process in the lower part of the container 1.
- the flow labyrinth according to the invention which brakes the air flow, can be formed not only, as in the exemplary embodiments described above, by the ribs, elevations or projections integral with the respective container wall, but according to a further exemplary embodiment of the invention are also formed by an inner shell which lies against the smooth inner surface of a container wall and is fastened thereon and which contains the flow body forming the flow labyrinth and lies against the smooth inner wall of the container wall.
- the container consists of a thin-walled outer plastic shell with a smooth inner wall, produced in a first production step, and a thin-walled inner shell, produced in a second production step, with the ones shown above Embodiments formed, formed in the inner shell rib-shaped, scale-like or other air guiding elements.
- This inner shell can be made in one piece or for all container walls be designed as an inner wall element designed separately for each container wall.
- the respective hollow inner wall element is connected to the outer container wall part or to the outer shell of the container by means of adhesive connections, or snap connections or other positive connection means. In this way, dimensionally stable sandwich elements composed of thin-walled, inexpensive to produce wall elements are produced as container walls, which due to the double walls also have excellent thermal insulation.
