Definitions
- the invention relates to a rotary drum for drying free-flowing material according to the Preamble of claim 1.
- Such a rotary drum is from DE-C 33 45 118 known.
- Cross internals are also known from DE-B 23 62 725 and from DE-B 29 11 137. They are for drying strands, 5 to 50 mm wide and 75 to 150 mm long wooden parts, OSB boards are not made from. A rotary drum with tight arranged cross internals, as used for drying wood chips, would easily clog when drying strands. If you increase the Distance between the cross internals, so the heat transfer from the drying gas to the goods too low. In addition, they have the disadvantage of relatively high manufacturing and installation costs.
- trickle internals for a rotary drum are described in DE-B 18 04 154. These trickle internals have radially inserted, partially permeable, the cross section of Drum row walls dividing into equal sectors, which over openings consistently connected with each other.
- the cell walls are on their inside According to the direction of rotation of the drum on the rear side equipped with webs, soft running almost vertically on the walls and parallel to the drum axis are arranged. Furthermore, are on the inner periphery of each sector Lifting paddles arranged. With this arrangement, the material trickles from the internals of a sector almost at the same time. In the last part of the drum rotation are the Sectors therefore only slightly filled. The distribution of the goods over the cross section of the Drum is uneven.
- the cross section is also divided into cells by built-in cells. Intermediate sheets that serve as throwing bars are all of a shape and size. You divide that by an outside or an or several inner drum tubes formed circular mantles in cells. Disadvantage of this strong The division into cells is the lack of circulation of the entire good. A Uniformization of a different degree of moisture of the incoming goods in the Different cells are not possible in the course of drying.
- From DE-C 33 45 118 is a generic device for drying sugar known with a rotary tube.
- the rotary tube is inside with several Circumferential sets of outer, evenly distributed trickle blades equipped. All outer trickle blades of a circumferential set extend in the axial direction a certain length of the rotary tube.
- the outer trickle scoops in a row arranged circumferential sets are staggered.
- At the center of the Rotary tube is an installation fastened to the rotary tube with an elongated support, which is provided on the outside with inner, approximately radiating trickle blades, intended.
- These trickle internals are also for drying the lighter wood chips and beaches not suitable.
- the fall distances inside the rotary tube are too large. Is too the total area of the internals is too small for effective heat emission.
- the object of the invention is a rotary drum for drying free-flowing material to develop according to the preamble of claim 1 for drying wood chips and is suitable for drying strands, good heat transfer from Allows drying gas on the goods and their manufacturing and assembly costs are at least not higher than those of cross internals.
- a rotary drum according to the invention is particularly suitable for drying wood chips and beaches and chip material with long chips, but also for drying other, free-flowing Suitable material.
- the internals extend from the circumference in the direction Drum center in the form of a beam over a larger area of the drum radius.
- the area is at least 60% and at most 85% of the drum radius.
- Cross fittings are somewhat cheaper to manufacture.
- welded cross internals can be radiating internals
- the radiating internals can, if they consist of one part, only be attached to the circumference of the rotating drum. They can also consist of two parts, the outer part on the circumference of the Rotary drum is attached and the inner inside, for example on an inner tube. In both cases, the assembly is easier than that of cross internals.
- the material is broken down into several sub-piles by the radiation-shaped internals.
- the Extension of the internals over 60 to 85% of the drum radius enables a large one Installation area.
- the larger the installation area the sooner the surface of the goods and the Dwell time of the goods in the rotating drum can be increased, and the better Heat transfer.
- the radial internals form from the circumference to the center of the drum at least two pockets.
- a bag becomes two in one in the direction of rotation itself opening angle, for example 90 degrees, arranged to each other Sections of the radiating internals formed.
- the first section is one Pocket often arranged approximately radially.
- the second section of the first bag closes either directly, in the case of one-piece radial installations, or after one small, e.g. B. bridged by a baffle, the first section of the gap second bag.
- Training with bags and one more Section leads to a cascade-shaped configuration of the radiation-shaped internals.
- the goods are further divided by the pockets and when they trickle out of the pockets distributed over the drum cross-section during the rotary movement. You decrease that Stretch free fall and ensure that the goods are circulated and loosened up.
- the course of the radial internals begins approximately on the radial beam their attachment point on the circumference and continues by training the pockets in front of the Radial jet away. If you divide the drum cross section into by the attachment points limited sectors, so paint over the radiating internals on their way to Drum center at least half of their sector in front of the radial beam. Especially at A large number of radiating internals can cover the entire sector paint over and protrude towards the middle of the drum into the next sector. This course of radiating internals causes their pockets to be emptied one after the other during operation be, especially that in half of the drum cross-section to the direction of rotation well, trickles well out of the pockets.
- the extension up to the middle of the drum, the formation of at least two Bags and the course of the radiation-like internals in the upstream sector enable a homogeneous distribution of the trickling material over the drum cross-section, a large drying area and thus good heat transfer from the drying gas on the estate.
- Structurally simple and thus easy to manufacture and assemble are one-piece, radiating internals each from a mounting sheet according to claim 2.
- Zur Stabilization are the mounting plates of a set on one or more, along the Drum axis one behind the other, for example at three points, one in the Start area, one in the middle and one in the end area, by circular arranged Connected to each other. Through these connectors also balls that form when drying long, low density beaches can, dissolved or adhering good parts detached from each other.
- Pipe sections with a round diameter are particularly suitable.
- baffle plates in front of or behind a set of radial Installations according to claim 7, wherein a baffle plate as a round, central disc or as middle or outer ring can be formed, extended by stowing the goods Dwell time.
- the trickling of the goods out of the pockets can be varied even more.
- the emptying the different pockets can be pulled apart better in time, so that the Distribution of the material flowing through the cross section is even more homogeneous.
- Fixtures with different lengths some of the fixtures closer to The middle of the drum protrudes than the others and has the advantage that the product is without Risk of blockage is evenly distributed in the middle of the drum.
- claims 9 to 11 are particularly for wood chips and beaches and goods, which have a similar drying and trickling behavior as this, suitable.
- Opening angle of the pockets from 70 to 140 degrees according to claim 9 position angle of the Pockets from 10 to -30 degrees to the radial beam, the angle between the radial beam through the top edge of the first section and the first section a pocket is defined and the tracing of the position angle to the direction of rotation is related, according to claim 10 and the heights and widths of the bag, which by the Lengths of the first and second sections are set according to claim 11 a homogeneous distribution of the material flowing through the cross section.
