- the respective bulk material by a to promote lying drum having a bunch of axially parallel tubes, through which the hot heat carrier is preferably passed in countercurrent. Due to the drum rotation, the tubes of the tube bundle through the Bulk material led, in the direction of rotation of the drum along the drum shell taken to a limited by the respective angle of repose height becomes.
- the drum with a comparatively low circulation speed is driven, have the tubes for the heat carrier especially on the side of a distributor head for feeding the hot Heat transfer fluid over the drum circumference different temperatures, because just the tubes of the tube bundle during a drum rotation successively be guided through the bulk material. This may result to prevent the bulk material from being conveyed through the drum can be heated sufficiently evenly.
- the invention is therefore based on the object, a device for Heat treatment of a flowable bulk material of the initially described Art with relatively simple constructive means to design so that an advantageous temperature control within the bulk material over the length the drum can be guaranteed.
- the invention solves the problem set by the fact that the tubes of the Tube bundles are axially divided and that the distributor head associated shorter pipe sections with the longer connected to the collecting head Pipe sections over one with a radial distance from the drum shell held mixing chamber in flow communication.
- the temperature control within the bulk material is an essential Prerequisite for a heat treatment that meets even higher requirements of the bulk material. Another requirement is compliance a predetermined treatment time, ie the residence time of the bulk material in the drum, to see.
- a predetermined treatment time ie the residence time of the bulk material in the drum.
- the drum on the Gutaustragseite one in the housing part with the Gutaustrag opening outflow section of the remaining drum is separated by a baffle plate, and at least one of the baffle plate upstream, radially attached to the drum shell Have discharge cylinder, the at least one outlet opening to the outlet section and an adjustable over the axial length of the outlet opening Owns piston.
- the radially attached to the drum discharge cylinder is in the area of the resulting before the baffle plate bulk bed below given conditions filled with bulk material, that in the cylinder jacket provided outlet opening dosed into the outlet section of the drum discharged and from there the Gutaustrag of the connected housing part is promoted.
- the outlet opening adjustable Piston can be the free passage cross section of the outlet opening set sensitively, so that at a correspondingly metered task of treated bulk material to the Guteinlauf the residence time of the bulk material depending on the rotational speed of the drum and its inclination can be controlled precisely.
- the piston of the discharge cylinder by one with a drive interacting spindle drive can be adjusted.
- the drive for the Spindle drive from a drive wheel mounted on the spindle with a rack and pinion toothing consist of two with respect to one another to the drum vertical plane through the spindle opposite, respectively between an exemption and an engaged position adjustable, the frame assigned Mitauerzapfen cooperates.
- the drive wheel of the spindle Have a friction ring, so that the friction wheel thus obtained on frame-fixed Runways can be twisted to adjust the piston for adjustment To actuate the outlet opening of the discharge cylinder.
- These runways the again with respect to a plane perpendicular to the drum through the spindle are opposed to each other for their use in an analogous manner to the Moving driving pin from an exemption to a working position.
- the gimbal support of the counter flange ensures a rich concern the mating flange on the rotating sealing flange of the distributor or Sammelkopfes, so that all relative movements between the Zu- and Discharges on the one hand and the distribution and collecting heads on the other receiving Mechanical seal is obtained.
- For taking larger axial Relative movements extends the axial spring preload of the counterflange not from.
- the gimbal support of the Counter flange on a parallel to the supply and discharge guide displaced stored and in the direction of displacement against a connection of the Distributor or collecting head are supported, so that the gimbal Supporting the counter flange axial movement of the connection end of the Join distribution and collection heads.
- the illustrated device for heat treatment a free-flowing bulk material, a drum 1, the between two end-side housing parts 2, 3 of a frame 4, not shown is mounted rotatably on pulleys 6 via trolleys 5. Inside the drum 1 an axially parallel bundle of tubes 7 is provided, on the one hand at a Distributor head 8 and on the other hand connected to a collecting head 9 are.
- the hot heat carrier is the distributor head 8 via a supply line 10th supplied and withdrawn from the distributor head 9 via a discharge line 11.
- the Connections 12 of the heads 8, 9 pass through the housing parts 2, 3, so that the Connection between the co-rotating with the drum 1 connections 12 and the frame-fixed inlet and outlet lines 10, 11 outside the housing parts 2, 3 are.
- the tubes 7 of the tube bundle are axially separated from each other Pipe sections 7a, 7b divided, wherein the shorter pipe sections 7a from Distributor head 8 go out and the longer pipe sections 7b in the collection head 9 open.
- a mixing chamber 13 provided, in which a different temperature having partial flows the heat carrier from the line sections 7a are mixed, around the line sections 7b with a heat transfer medium uniform mixing temperature to be able to act on.
- the mixing chamber 13 which with Radial distance is arranged to the drum shell, opposite the drum 1 in the circumferential direction against rotation, in the axial direction but slidable in about
- the supports distributed circumferentially drum 14 stored.
- the bulk material to be treated is a metering lock 18 a in the housing part 2 provided Guteinlauf 19 abandoned and enters an inlet cone 20 of the drum 1, which extends with helical Support strips 21 is provided. From the inlet cone 20 is the treated Bulk material at the collecting head 9 by one of the drum 1 formed Paddle wheel 22 fed, over which the bulk material through a central feed opening 23 in the actual treatment room of the drum. 1 passes to the drum mantle to the provided pipe mounts 17 to be conveyed over to the outlet section 16 of the drum 1.
- the pipe mounts are for this purpose as the mixing chamber 13 with held radial distance from the drum wall.
- the outlet section 16, which is provided with helical conveyor bars 24 is different from the rest Drum 1 separated by a baffle plate 25, the overflow opening 26th may have to prevent overfilling of the drum with bulk material.
- the baffle plate 25 are distributed over the circumference of the drum 1 discharge cylinder Preceded 27, as shown in FIGS. 2 and 3 in more detail.
- These Discharge cylinder 27 are arranged radially to the drum 1 and point in the Outlet portion 16 opening, substantially axially to the discharge cylinder 27th extending outlet openings 28, whose free passage cross-section with Help a piston 29 can be adjusted.
