DE202011003735U1 - Containers for the metered discharge of shredded or shredded biomass and bulk materials such as wood chips, wood chips, sawdust and straw - Google Patents

Abstract

A usually funnel-shaped container (1) for storage and buffering and for the metered discharge in particular of biomass and bulk materials such as wood chips, wood chips, sawdust, crushed straw, Miscanthus etc. characterized in that the container bottom a discharge device (1) is mounted consist of one or more knife-shaped discharge shafts (3),

Description

Pelleting presses for the production of smaller quantities of biomass pellets for animal feed or for heating purposes are usually fed manually by shoveling the pellets into the feed hopper. This leads to a discontinuous processing whereby no consistent quality such as mechanical strength, abrasion behavior and hardness of the compacts can be achieved.

Furthermore, the machine can not be operated for a long time without operator, as regularly material must be supplied.

This problem is solved with the features listed in the protection claim 1.

The invention relates to a usually funnel-shaped container for storage and buffering and the metered discharge particular of biomass and bulk materials such as wood chips, wood chips, sawdust, crushed straw, Miscanthus etc. with a mounted on the container bottom dosing consist of one or more knife-shaped discharge shafts.

• a) Die Ausführung der Messer, wie deren Länge und Breite sowie die Anzahl der Klingen, der Messer die auf der Messerwelle oder den Messerwellen angeordnet sind bestimmt.
• b) Die Anzahl der Messer auf der Messerwelle oder den Messerwellen bestimmt.

The amount to be discharged is determined by:

• a) The design of the knives, such as their length and width and the number of blades, the knife which are arranged on the blade shaft or the cutter shafts determined.
• b) The number of knives on the knife shaft or the knife shafts determined.

• c) Einstellung der Drehzahl der Messerwelle oder der Messerwellen eingestellt.

In the production plant, the quantity to be discharged is determined by:

• c) Setting the speed of the blade shaft or the cutter shafts set.

The invention provides a feeding device is provided, for example, is preceded by a pelleting press as a warehouse or buffer tank with the biomass is fed evenly whereby a continuous automated production operation is achieved with high consistent quality.

The invention is characterized by its simple, robust and low-maintenance construction. It is made up of a few easy-to-manufacture parts. The dosing quantity can be adjusted by adding or removing it, or it can be adapted to local conditions by exchanging it with longer or shorter knives.

In order to prevent bridge formation of the metered material, one or more shafts with one or more stirring arms or rods can be connected upstream of the blade shaft (s) in a vertical or horizontal arrangement.

An embodiment will be described with reference to 1 to 3 explained. Show it:

1 Container with discharge in a lateral sectional view.

2 Discharge device in a view from above.

3 Knife shaft with knife.

4 Blade shaft with multi-blade knife

With 1 becomes a funnel-shaped container 1 for shredded biomasses refers to the bottom of a discharge device 2 is located over one or more waves 3 has the several knives 4 are equipped. So that the dosing material can not trickle uncontrollably becomes the comb 5 used.

One or more stirrer shafts can be placed over the cutter shafts 6 be attached, which serve to loosen up and avoid bridging.

2 shows the discharge and metering device with the rotatably mounted blade shaft 3 and the knives 4 (here 3 ) continue to comb 5 for sealing.

Knife ( 3 ) with different number and length can be used to adjust the discharge rate.

Multi-blade knife ( 4 ) with different number and length can be used to adjust the discharge rate.

Claims (7)
