DE4000916A1 - Drum for composting organic material - comprises wooden or plastic drum with loading flaps and divided at right angles to and rotating about main axis - Google Patents

Abstract

A compost bin consists of a wooden or plastic drum divided by a wall into two chambers at right angles to the central axis. The drum can be ventilated and rotates about the main axis. Filling and emptying is achieved by lockable flaps. The twin chamber system allows simultaneous composting and filling to occur. USE/ADVANTAGE - The bin can be used for composting, e.g., garden rubbish and allows optimisation of the composting process.

Description

The invention relates to a device for composting of organic material that is predominantly in a be made of wood or plastic drum stands that are perpendicular to their longitudinal axis in two or more sections (chambers) divided and mo toric or rotatable around its longitudinal axis by hand is.

The loading and unloading of the drum chambers itself from the subdivision perpendicular to the longitudinal axis give, takes place via lockable flaps.

Composting drums in very different sizes and various building materials are in use. They are mainly operated continuously. On the front side, rotting material is continuously added and removed the other end. This mode has u. a. the disadvantage that the conditions for an optima len rotting process (moisture, C / N ratio, Air entry, different dwell time depending on Material u. a.) are not easily adhered to. Batch operation, on the other hand, H. To fill - Composting - emptying allows this optimization rotting process.

Since in many cases, e.g. B. in households, gardens etc., the material to be composted almost continuously accumulates, it must be accumulated until one (for Start the rotting process) enough large amount  has come together. This is uncomfortable because of it the transfer work from the collective depot to the drum, because of the food leftovers collected Ä. attracted animals (flies, mice, rats etc.) and because of the possible smell from the collected, piled up organic material.

These shortcomings are suggested by the here New construction fixed that at z. B. two existing drum chambers one of the chambers (A) to accumulate the constantly occurring compo bull material is used until the optimal Amount of material or the opti Male degree of filling of chamber A is reached. Then this chamber A is closed and the neighbor chamber B opened. In the closed chamber A the rotting process can now run. Chamber B now serves to accumulate until it is the optimal Filling has reached. Then it closes and the now rotting material from the Allow chamber A to drain. From then on it serves as Accumulate while the rotting process is in progress in B. So the cycle is in alternate use chambers A and B for collecting and composting closed.

The disadvantages of the previous ones described above Drums and composting processes are so raised.  

The execution of the chamber drum can be very good. An example of FIG. 1 and FIG. 2 schematically.

The drum body ( 2 ) is mounted in the support frame ( 1 ) over the longitudinal axis ( 3 ). The lockable flaps ( 4 ) and ( 5 ) serve to fill and empty the chambers A ( 6 ) and B ( 7 ). The partition ( 8 ), which che che said chambers in the drum body ( 2 ) bil, is perpendicular to the longitudinal axis of the drum.

Claims (2)

1. Device for rotting organic material, e.g. B. plant waste, food waste, etc., with a rotatable about a longitudinal axis drum body, characterized in that this drum body is divided perpendicular to its longitudinal axis by means of partitions in two or more chambers, each of which can be loaded or emptied by flaps. 2. The use of the device according to claim 1 such that the chambers alternately to collect and Serve composting the filled material.
