"Charging chute equipped with internal brakes, especially for waste incineration plants"

In the case of charging chutes for large incineration plants, it is known, fixed and movable impact or brake internals to prevent falling from above ■ Fuel too as a result of the sliding surface that has become shiny quickly slides into the furnace. Impact or brake installations, that should prevent this are, among others. has been proposed in the form of swiveling into the chute Segment bodies, oscillating plates or spindle rods that can be rotated into the chute.

For the same purpose it has also been proposed to provide the loading chute with kinks. However, there is a risk that the desired The purpose is achieved too extensively, d. H. that blockages occur at the kink point.

In addition, since household waste is not only of a constantly changing composition, especially with regard to has moist components, such as fruit and vegetable waste, but also in the garbage collection bunkers of the Incinerators are often and even under great pressure from the younger amounts of waste stored above them sometimes it has to stay in the bunker for up to 5 days before the gripper puts it in the feed hopper of the furnace promotes, the behavior of this garbage in the ^ loading hopper and the subsequent fall is also churning very different, d. H. the coefficient of friction changes constantly. This means that it is very humid or garbage already partially fermenting too little adhesion to the side surfaces of the feed chute has so that he tends to follow up ■■ more quickly; slip than the one at the bottom of the garbage chute '; located charging device, which works as a volumetric charging device, due to the P set speed or number of strokes per unit of time should transport. The aforementioned, previously known impact internals in charging chutes could due to the mentioned nature of the garbage, but also because of its long-fiber structure, not the required Bring stabilization in the chute, especially since z. B. also when attaching a larger number from known impact internals, in turn, slipping the often very bulky components contained in the garbage would be prevented.

The present invention is based on the object of providing a remedy here. This task was solved at a feeding chute provided with movable internals, especially for waste incineration plants, in the The main thing is that the brake plates are hinged to the chute wall and change the fuel flow their braking effect can be regulated * A preferred one Embodiment of the invention provides that the brake plates are connected to adjustable compression springs from outside the chute. The swinging brake plates exert a greater braking force on the garbage in the chute, the further away it is from the garbage from its rest position be displaced *

Each brake plate 2 is suspended from the chute wall in a swinging manner. According to embodiment a, the pendulum, /, movements of the brake plates 2 are inhibited by guided springs 3, the pressure or resilience of which can be adapted from the outside to the 'nature of the garbage, for example, that the outer support 4 of the spring is adjusted in any ¹ way in the indicated arrow direction ".

So that garbage parts get caught in the hanging storage 8 can be prevented, this is against the chute interior provided with a shield 7 that can be used in all embodiments.

According to embodiment b, the adjustable Braking effect of the oscillating plates, 2 by a weight accomplished, the awf one with the plate 2 rigid connected arm 9 is slidable.

In the embodiment c, a weight 6 which can be adjusted in the direction of the arrow is fastened on the side in a brake plate 2. With this simplified possibility of guiding the invention, distribution during operation is possible if the cover plate 10 is opened beforehand.

In a loading chute 1, which can be perpendicular or inclined in any direction, one or more oscillating brake plates 2 can be mounted one below the other and / or on top of one another.

The brake plates 2 can also be produced in a shape other than that shown, for example as segments be. It is also provided that the Eutschfläche of the plates 2 to increase the braking effect, possibly. additionally roughening.
