Definitions

  • Characteristic of the discharge of kiln, for example Cement clinker, at the outlet end of a rotary kiln is that the coarse material in the lower part of the spout, the fines however, in the area of the spout rising with the rotation is dropped. Considering the discharge stream over its width, it is therefore found that the coarse material mainly on one and the fines mainly on the other side is to be found.
  • the one Area of the discharge stream, in which mainly the coarse material is located as a coarse material discharge area, and the other Part in which mainly fines are located, as Fine dump area called. It depends on a precise Delimitation of these areas not.
  • the invention is based on the object, the discharge stream to equalize. It achieves this through the measures according to Claim 1 or 6 and preferably in the subclaims mentioned features.
  • the invention provides that at least a portion of the combustible material from the coarse material discharge area to the side of the fine material discharge area and / or at least part of the fines dump area promoted to the side of Grobgutabsch ceremoniess out before the discharge stream reaches the cooler. The demixing is thereby largely reversed.
  • the kiln has the following side of the promotion cooler within the meaning of claim 1 then achieved if it is the place has reached at which the cooler its intended cooling effect unfolded. In the case of a grate cooler, this is the Cooling grid or the good bed lying on the cooling grid and not already the entry into the radiator housing. The invention Procedure can therefore also take place in the radiator housing, however not until then when the good is the good bed of the cooler has reached.
  • the equipment used for it - cooled.
  • This can also be used to specifically lower the temperature of the good, in particular of the fine material.
  • the cooler fines can then be placed in front of the coarse material on the cooling grate be deposited the adjoining cooler to a to make protective layer that the cooling grid of the hot, separating coarse material.
  • An arrangement for equalizing the Brenngutabiness features the fact that in the Grobgutabment Scheme a for Side of the fines disposal area directed towards conveyor and / or in the fines dump area one to the side of the Grobgutab scheme Schemes directed conveyor the dem Radiator is connected upstream.
  • a device can in the simplest case of an inclined surface, for example a chute, exist. If a motor driven Conveyor is selected, this can for example by a Screw conveyor, a plate belt or a vibrating grate be formed.
  • the conveyor as a roller whose axis is transverse to the direction of the rotary kiln and thus in the direction of the lateral extent of the discharge stream is arranged, wherein the roll surface a Boundary wall is adjacent. That in the wedge between the Roll surface and the boundary wall located Good, the too coarse to go through the gap between roll surface and Wall falling, becomes a conveying action along the roller subjected by inclination of the roller and / or the wall and / or suitable conveying elements on the roll surface or may be caused on the wall.
  • the wedge space between the by rotation of rising side of the roller and an adjacent Boundary wall because the leading out of this wedge space Movement of the roll surface the material auflokkert.
  • the roller is therefore conveniently located so that the discharge stream initially on the rising side of the roller arrives.
  • the waste line of the estate hits the wedge area (including the roll surface to the top of it). It is understood, however, that he is also on the descending Side of the roller (if there is a corresponding boundary wall is provided) can be performed when the risk of caking of the fuel does not exist.
  • Conveying action is not limited to one side of the roller. Rather, in addition to the wedge space between the roller and a boundary wall on the rising side of the roll a corresponding wedge space provided on the descending roller.
  • Part of the estate, not already in the first of discharged from the river, or falls through, is carried by the roller in the other wedge space over and there promoting and optionally refractive processed.
  • the processing conditions differ in This other wedge space substantially from those in the first. To the one is the proportion of coarse material larger.
  • there is the material in the wedge-gap rolling roller movement other and more intensive editing options available for the Promotion and, where appropriate, to reduce the estate targeted can be used.
  • the wall involved becomes therefore referred to as a crushing wall.
  • the width of the passage between the roll surface and the boundary or breaking wall is expediently adjustable. First, the position of the wall can be changed, but also the position of the roller.
  • the roller surface and boundary wall formed device to the fines throw-out area inclined. More specifically, the wedge space between roller and Boundary wall have this tendency. This inclination can on the inclination of the roller and / or the inclination of the boundary wall based. This tendency causes that because of their Size in the wedge space lingering pieces due to the Gravity effect gradually migrate towards the fines discharge side. On the other hand, it can be provided that the fines are relatively quickly falls between roller and boundary wall or in the manner explained below a transport is subjected in the opposite direction. Instead or In addition, the surface of the roller with conveying elements equipped and / or formed from such elements.
  • Boundary wall carry conveyor elements.
  • the conveying effect is due to inclination, this tendency can be due to taper of the roller; i.e. more generally, the roll diameter increases Fines disposal side down. This diameter decrease needs not to be even but is beneficial for one economic production in stages. This stage version will be included in the concept of conical shape below his. The more individual pieces of the material through the roller rotation be lifted out of the wedge, the stronger makes the slope based on the taper of the roller noticeable and therefore the stronger the promotion effect.

  • the equipment of the roller with a larger diameter the coarse material discharge side also has the advantage that the roller on this page a larger and faster moving surface for the processing of coarse material provides while on the fines discharge side because of the greater crop failure the density of the product is lower. If the roller is in stages is formed, it may be appropriate, even the boundary walls (seen in the longitudinal direction of the roller) accordingly to train in stages.
  • the crushing wall can also be in sight be stepped on a plane transverse to the roll axis plane, so that the step edges exert refractive effect on the coarse material can.
  • the roller a screen coat on.
  • She is hollow, and her coat contains openings through which fines fall through can. It then enters the interior of the roller, the bottom surface in conical design of the roll shell and about horizontal position of the roll axis to Grobgutabschseite out drops.
  • the fine material is thereby in the direction of Grobgutabschseite promoted. It may be appropriate, the largest Part of the fine material to get into the interior of the roller. Only a small proportion of fines then falls through the preferably adjustable gap between roll surface and Boundary wall.
  • Roll shell forming webs be designed so that they Penetration of the fine material into the roller promote its falling out but inhibit. For example, they can run flat be and against the radial direction outward in the direction of rotation be inclined forward. This can also be considered a scaly one Arrangement are called.
  • the outer Roll surface is rough. Under roughness is in this context the equipment with protrusions or bumps too understand. These include, for example, the ones mentioned above Conveying elements whose inclined relative to the circumferential direction Areas exert a promotional effect on the good. Furthermore belong in addition to that areas, the lifting of coarse material from the wedge space on the rising side of the roller to favor Take this good over to the descending side of the roll. After all, these include elements that work together with the crushing wall exert a crushing effect on the coarse material.
  • a scraper be arranged above the Roller. It is about about a parallel to the upper surface line of the roller stored Beam or a more or less closed series of individual elements.
  • the beam or the elements are expediently yielding, z. B. oscillating, stored.
  • Your distance to the roll surface is expediently adjustable.
  • the wiping action is that on the rising Side of the roll surface raised, rough Good in particular in case of unusually strong accumulation evenly over the roll length is distributed and thereby a local blockage the device is prevented. Part of the estate is due to the wiping action in the wedge space on the rising Roll side fall back and thereby along the roll axis transported to the fines side.
  • This Effect can be achieved by equipping the scraper with a parachute-like, to the circumferential direction angularly employed plate elements be strengthened.
  • On the other hand with appropriate Adjustment of the scraper distance to the roller surface a crushing of coarse pieces done. Pieces that smaller than the wiper distance from the roll surface are carried over to the falling side of the roll.
  • It several such scrapers behind the other on the roll circumference be arranged, which expediently in Direction of rotation of the roller decreasing distance to the roller surface have, so that a multi-stage crushing of the goods he follows.
  • the multiple scrapers can be independent of each other or stored on a common swing axle his. You can by spring or weight in the desired Distance adjustment pushed to the roll surface become.
  • the aforementioned crushing wall on the descending Roll side can be replaced by one or more scrapers his. But it can also be provided in addition.
