Definitions

the invention relates to a dryer for treating garden waste, so-called green waste, and other bulk material, such as wood chips.
dryers comprising a container with a double bottom.
a first floor is arranged above another.
the upper floor is perforated. Through the perforations, drying air is introduced into the space above the first floor.
drying does not take place uniformly, resulting in a moisture gradient in the product.
belt dryers there are belt dryers.
the material to be dried is applied to a conveyor belt and blown with air, for example coming from above or from below.
air for example coming from above or from below.
the dimensions of such belt dryer are very large.
the band is not always evenly occupied.
tower dryer There are known tower dryer. These include a tower-shaped container. The material is introduced into the container above and peeled off below. The flow of drying air is always non-uniform. There is also a risk of clogging.
drum dryers In drum dryers, the material is entered at one point in a drum and discharged at another point again.
air is in the Blown dryer. The air entrains the light wood particles in the direction of discharge, so that the residence times are small or complicated installations are required, which complicate the maintenance and cause a risk of clogging.
Another disadvantage is that the residence times in the drying of wood particles to wood particles are unequal. At low temperatures, the tumble dryer works uneconomically. He is therefore very tall.
fluidized bed dryer in which the material to be dried is transferred to a fluidized bed (floating bed).
a fluidized bed floating bed
the particles have a certain weight or tend to snag each other, such as wood chips, but the good is not thoroughly mixed. The drying is therefore not uniform.
GB 843,705A describes a dryer for drying wood chips "comprising an elongate horizontal container having an inlet at one end and an outlet at the other end The container wall is partially perforated The perforations are connected to compressed air There are conveyors arranged in an ascending quadrant the container wall grab the good and promote along the container wall by a certain distance upwards, that is in the circumferential direction of the container.
US Pat. No. 6,189,234 B1 such as DE 29 24 523 A1 describes driers for drying solid, free-flowing materials, also with compressed air nozzles and conveying means in the first ascending quadrant of the container.
the invention has for its object to provide a dryer that has a simple structure, achieved a uniform drying, long residence times with low volume and allows cost can be produced.
the dryer should be particularly suitable for drying the aforementioned good.
the container may be designed as an upwardly open tray or tray. It can be closed, for example as a cylinder. It may have a circular cross section or an elliptical cross section or another cross section. It is important that its bottom is at least partially rounded.
the good but is guided by the said funding in the ascending quadrant of the container wall up a certain distance along the container wall up and then tilts to the center of the container.
a rolling movement of the material or a material layer is generated.
the estate thus performs two movements: On the one hand the Walking movement from the inlet to the outlet of the container, on the other hand, said rolling motion. Compression of the goods is avoided.
the good is lifted by the conveyor and transferred into a rolling motion. It forms a good roll, which is located substantially in the region of the ascending quadrant, and thus fills only a relatively small part of the container cross-section.
the main mass of the material is guided upward in the region of the ascending quadrant of the soil until it tips over towards the center.
the estate is located only in the area of the ascending quadrant. It thus fills only a part of the cross section of the container, as shown, less than half of the cross section.
Container 1 has a round cross-section.
Container 1 is thus essentially a cylinder. It has an inlet 1.1, an outlet 1.2 for the material to be dried.
FIG. 1 can be seen a plurality of perforations in the container bottom.
the perforations may be of any shape, such as holes or slots. They serve to pass compressed air from the outside into the container interior. See arrows 2.
the container has a conveying member 3, comprising a conveying shaft 3.1 and conveying arms 3.2. How to get out FIG. 1 detects, the conveying arms 3.2 are curved. The curvature is a convex, seen in the direction of rotation. See arrow 4, which illustrates the direction of rotation of the conveying member 3.
the curvature of the conveyor arms 3.2 has the following meaning: The surface pressure exerted by each conveyor arm in its circulation on the estate is thereby minimized, and thus a blockage or a nester formation in the estate.
the conveyor arms thus act like blades.
the material 5 collects in the region of the ascending quadrant of the container wall. It executes a rolling motion. See the two arrows 6.
the ascending quadrant represents a kind of rolling bed.
the compressed air is generally supplied in all embodiments preferably in the ascending quadrant of the container wall. However, it can also be introduced outside of this quadrant by appropriate perforations.
the dryer according to FIG. 6 comprises a container 1. This is again designed as a reclining, elongated cylinder. At the end of the outlet 1.2 is a shut-off 1.4.
a conveying member 3 is provided, analogous to the conveying member according to the Figures 1 and 2 with shovel-like conveyor arms.
a chamber 10 below the container 1 is a chamber 10. It has one or more air connections 10.1. It lies sealingly against the bottom of the container 1 and is open towards the periphery of the bottom so that the air forced into the chamber 10 can enter the container interior through the perforations 1.3 of the bottom of the container to act on the product 5, in the sense of loosening up and turning around.
Chamber 10 is conical in cross section. It is equipped with emptying organs. Within the chamber 10 is a screw conveyor 11. At the end of the screw conveyor 11 is an outlet 11.1.
the dryer according to FIG. 6 works as follows: Through the inlet 1.1, the material to be dried is introduced into container 1.
the good may in turn be any bulk goods, such as crumb-like substances, green waste, grain, biomass, plastic granules, wood chips, fiber.
container 1 In container 1, a certain level of the goods 5 sets during operation.
the rotational speed of the conveying member 3 is adjustable.
An intermittent mode of operation is also conceivable.
the container 1 has at its downstream end an overflow weir 1.5.
FIGS. 7 to 9 show different embodiments of the chamber 10.
the perforations extend in this case not only over the ascending quadrant, but also over the preceding sloping quadrant.
the treated material is dry and free from unwanted components. It can be processed into pellets or briquettes. It can be burned directly. Also, a use in pyrolysis into consideration.
