Abstract

A compost leachate distribution device includes a composting chamber for receiving material to be composted and a leachate collection chamber for collecting, via a leachate fluid path, leachate generated during composting in the composting chamber. The device has a leachate mixing arrangement a first inlet for receiving a flow of water, a mixing chamber to which the first inlet leads for mixing water with leachate to form a water/leachate mix and an outlet leading from the mixing chamber to the exterior for exit of the water/leachate mix, wherein the leachate mixing arrangement has dosing means for controlling a rate of flow of leachate from the leachate collection chamber into the mixing chamber.

First claim

The invention claimed is:

1 . A compost leachate distribution device comprising a composting chamber for receiving material to be composted, a leachate collection chamber for collecting, via a leachate fluid path, leachate generated during composting in the composting chamber and a leachate mixing arrangement comprising a first inlet for receiving a flow of water, a mixing chamber to which the first inlet leads for mixing water with leachate to form a water/leachate mix and an outlet leading from the mixing chamber to the exterior for exit of the water/leachate mix, wherein the leachate mixing arrangement comprises a dosing arrangement for controlling a rate of flow of leachate from the leachate collection chamber into the mixing chamber, wherein the leachate mixing arrangement comprises a venturi mixing tube provided between the first inlet and the outlet of the mixing chamber and a dip tube providing a fluid path from the leachate collection chamber to the venturi mixing tube, wherein the venturi mixing tube and the dip tube act as said dosing arrangement.

2 . A compost leachate distribution device according to claim 1 which comprises a base for supporting the composting chamber.

3 . A compost leachate distribution device according to claim 2 in which the composting chamber is arranged as a drum and the base is arranged for supporting the composting chamber for rotation about an axis of the composting chamber.

4 . A compost leachate distribution device according to claim 2 in which the base comprises a leachate chamber receiving location for receiving the leachate collection chamber during the collection of compost leachate.

5 . A compost leachate distribution device according to claim 4 in which the leachate collection chamber is removably receivable in the receiving location.

6 . A compost leachate distribution device according to claim 1 in which the compost leachate distribution device comprises a leachate collection bottle which defines the leachate collection chamber.

7 . A compost leachate distribution device according to claim 6 in which the leachate collection bottle comprises a leachate drip collection tray portion provided on an outer wall of the bottle.

8 . A compost leachate distribution device according to claim 7 in which the leachate drip collection tray portion comprises an inlet port for allowing collected leachate to enter into the leachate collection chamber from the collection tray.

9 . A compost leachate distribution device according to claim 8 in which the tray portion has an outer rim and a base of the tray portion is inclined in relation to the outer rim towards the inlet port.

10 . A compost leachate distribution device according to claim 1 comprising at least one vent portion provided on a wall portion of the compost chamber, wherein the at least one vent portion is controllable to control the amount of venting which is provided.

11 . A compost leachate distribution device according to claim 1 in which the compost chamber comprises at least one outlet aperture for allowing the escape of leachate from the compost chamber.

12 . A compost leachate distribution device according to claim 11 in which the compost chamber comprises a housing made of at least two parts with a respective join line between the at least two parts and the at least one outlet aperture being defined at said join line.

13 . A compost leachate distribution device according to claim 12 in which a groove is provided in an outside surface of a cylindrical side wall of the compost chamber and the at least one outlet aperture is provided in said groove.

14 . A leachate collection bottle arranged for use as part of a compost leachate distribution device according to claim 1 , wherein the leachate collection bottle defines the leachate collection chamber.

15 . A compost leachate distribution device comprising a composting chamber for receiving material to be composted, a base for supporting the composting chamber, a leachate collection chamber for collecting, via a leachate fluid path, leachate generated during composting in the composting chamber and a leachate mixing arrangement comprising a first inlet for receiving a flow of water, a mixing chamber to which the first inlet leads or mixing water with leachate to form a water/leachate mix and an outlet leading from the mixing chamber to the exterior for exit of the water/leachate mix, wherein the leachate mixing arrangement comprises a dosing arrangement for controlling a rate of flow of leachate from the leachate collection chamber into the mixing chamber, wherein the base comprises a leachate chamber receiving location for receiving the leachate collection chamber during the collection of compost leachate and wherein the leachate collection chamber is removably receivable in the receiving location.

16 . A compost leachate distribution device according to claim 15 wherein the compost leachate distribution device comprises a leachate collection bottle which defines the leachate collection chamber and the leachate collection bottle comprises the leachate mixing arrangement.

17 . A compost leachate distribution device according to claim 15 wherein the base comprises two leg portions and the leachate chamber receiving location is provided between the two leg portions.

18 . A compost leachate distribution device comprising a composting chamber for receiving material to be composted, a leachate collection chamber for collecting, via a leachate fluid path, leachate generated during composting in the composting chamber and a leachate mixing arrangement comprising a first inlet for receiving a flow of water, a mixing chamber to which the first inlet leads for mixing water with leachate to form a water/leachate mix and an outlet leading from the mixing chamber to the exterior for exit of the water/leachate mix, wherein the leachate mixing arrangement comprises a dosing arrangement for controlling a rate of flow of leachate from the leachate collection chamber into the mixing chamber, wherein the compost leachate distribution device comprises a leachate collection bottle which defines the leachate collection chamber, the leachate collection bottle comprises a leachate drip tray portion provided on an outer wall of the leachate collection bottle, the drop collection tray portion comprising an inlet port for allowing collected leachate to enter into the leachate collection chamber from the collection tray, and a removable inlet port blanking plug being provided for sealing the inlet port when leachate is not being collected.
