Definitions
- the invention has for its object the temperature stress and the wear of the conveyor grate in the initial area, especially on the drivers.
- the solution according to the invention consists in the feature of the claim 1 and preferably that of the subclaims.
- the driver one before the immediate Pass through the influx of well-protected anteroom, which contains an intensely chilled embankment before they enter the task area.
- a driver Once a driver has entered this vestibule, he pushes part of the material accumulated in it in the conveying direction. Other parts of the repressed good swell over him the direction of conveyance and are stored behind it with new goods entering the embankment on the stationary Rust surface from where it is at rest exposed to the influence of the cooling air until the next carrier appears to take them with them. Then they are already at a lower temperature assumed so that the driver only with pre-cooled goods in Touch comes. This shields him against the fresh, uncooled goods.
- the shape of the anteroom is not critical, provided it is on the top is covered such that the conveyor grate in the area of the vestibule is not hit directly by the feed stream.
- the height of the anteroom is substantially sufficient to accommodate the embankment is. In other words, their height is at least about everywhere just as high as it starts from the edge mentioned Slope angle corresponds.
- the upper limit of the anteroom from a direction opposite to the conveying direction sloping inclined surface.
- the height of the vestibule In some cases it is appropriate to raise the height of the vestibule a little lower than the height of the embankment, so that between the surface of the embankment and the upper boundary no space remains in the anteroom due to the cooling air can escape. This prevents the cooling air from to escape through the areas of the lowest height of the embankment. It can also be useful if the length of the anteroom, measured in the conveying direction of the grate, a little is shorter than the slope length, so not between the end of the embankment and the boundary of the anteroom A bulk-free area is created through which air can escape without cooling fired goods. This possibility can also be prevented in that the air permeability the grate area beyond the area covered by the Embankment is in any case taken, reduced or blocked becomes.
- the vestibule At a feed speed of the carriers of 0.5 m / min. the vestibule has a length of 0.5 up to 1 m proven.
- the longitudinal distance of the The carrier is expediently of the same order of magnitude. It should be greater than 0.8 times the length of the anteroom.
- the drivers in front of the anteroom are locked Pass through the channel, its length at least its distance equal.
- the limitation of the flow rate is expedient from a sloping surface sloping in the conveying direction formed, which ends in the edge mentioned, from which the Vestibule and embankment run out.
- the sloping sloping surface is expediently ventilated Rust plates equipped.
- the inclined surface can be made movable around build-up and caking (so-called snowmen) can be easily solved. It is enough i.d.R. an intermittent movement.
- the Inclined surface can be swiveled around one of the edges mentioned near the axis his.
- the edge of the bevel on the swivel axis far end, should be as close as possible to the Adjacent the adjacent wall.
- This wall is therefore expedient curved in a circular arc, the center of curvature coincides with the swivel axis of the inclined surface.
- the arcuate wall is expedient formed by ventilated grate plates that are polygonal in an arc are approximately laid.
- the arrangement can thereby be simplified that the lower run of the in a closed Loop guided grate conveyor as a drag chain conveyor is used. It lies immediately for this purpose or at a certain distance on a stationary Conveying surface on which the rust diarrhea arrives and from which it travels through the grate conveyor is dissipated.
- the drag chain conveyor can continue until the beginning of the conveyor grate, by the stationary conveyor surface of the drag chain conveyor forming wall in the area of the beginning of the conveyor provided deflection in contact with the conveyor until the material carried by it from the stationary grate surface or one located in the deflection area inside wall can be taken over the is continued from the stationary grate surface.
- the inside and outside wall that the conveyor at least on one include the length corresponding to the distance of the conveyor beams, form a seal for the rust subspace in relation to the sponsor.
- a suitable seal can also provided in the area of the other deflection of the conveyor his.
- the conveyor After leaving the grate surface, the conveyor runs through in the area of its deflection a sealing channel between one on the inside to the grate surface and a wall outside wall, which in its further course with the the lower run of the conveyor forms the drag chain conveyor.
- the conveyor grate 1 is contained in a housing 2, the one Has feed chute 3, in which, for example, the discharge end of a rotary kiln ends. It also forms one Outlet shaft 4, which may contain a crusher 5. details the housing design and the cooling air supply and -Laxation does not need to be explained because it is known.
- the conveyor grate consists of a stationary grate part 6, the Top forms a stationary grate surface 7, and one Conveyor 8, which is a pair of pull chains on either side of the stationary Grate part 6, the driver between them lead, in the example shown as so-called conveyor beams 9 are formed.
- the chains can be from wheels 10 be supported and led.
- the sponsor can also be in other Be fashioned, for example in the form of a or several screw conveyors.
- the decisive factor is that one A plurality of carriers is present in the conveying direction Have a distance from each other.
- the stationary grate part 6 contains cooling air through openings for supplied via the pressurized grate subspace 14 Cooling air.
- the rust subspace can - as is known - in several chambers can be divided, which allow different Sections of the cooler with different cooling air pressure to act upon.
- the conveyor is closed Loop guided, its upper run above the stationary Grate surface 7 runs and its lower run 11 in the grate subspace is returned. In between there is a task-side Deflection 12 and an outlet-side deflection. On their Details are given below.
- the hot kiln is fed into the feed shaft 3 from the furnace outlet thrown and forms a total of those indicated by arrows 16 Feed stream, this term nothing about the Density of this current is supposed to say.
- a material bed 17 is formed on the conveyor grate stationary grate surface 7 rests and from the movement of the conveyor beams 9 is taken in the conveying direction 18.
- the conveyor beams 9 expediently have such a large height distance from the stationary grate surface 7 that in between a stationary or weakly moving, relatively cool Good layer forms, causing wear on the stationary Rust surface is reduced. This can also be done with facilities be provided that the emergence of such a stationary Good layer by creating a sliding resistance promote. For example, depressions in the grate surface, Pockets, cross ribs, etc. can be provided that immediately hold onto or brake goods that interact with them.
- the distance between the drivers 9 and the grate surface 7 is expediently between 50 and 200 mm.
- the Bed height is in particular 400 to 1000 mm, the height of the Conveyor bar 100 to 250 mm.
- inclined surface 20 In the rear area of the feed chute (in the direction of conveyance) 3, where heavy chunks are expected to hit must be above the conveyor grate in the conveying direction sloping inclined surface 20 is provided. She will formed by grate plates used for their own cooling and for cooling the goods on it with a cooling air connection are provided.
- the inclined surface 20 is around Axis 21 by means of a suitable drive, which at 22 as Hydraulic cylinder is indicated, pivotable.
- the inclined surface 20 is normally in a certain one Tilt position stationary.
- the drive 22 can do this serve to set different angles of inclination. Especially it is intended for the inclined surface 20 from time to time swivel to throw off caking material induce or facilitate. For example, it can be intermittent periodically swiveling be relocated to the building of so-called snowmen submissions.
- the wall part 23 located behind the inclined surface 20 is the arc of movement of the trailing edge aligned the inclined surface 20 and also exists from ventilated grate plates.
- the material falling on the inclined surface 20 slips from it gradually descending due to the inclination, as a result of the Exposure to cooling air undergoes intensive cooling. It then falls onto the conveyor grate 1, in order for the Form bed 17. Part of the feed stream may also be immediate on the conveyor grate 1 or on the one located there Falling bed 17. However, these are smaller Pieces that the conveyor bar 9 does not hit when hitting strain, especially since they are largely protected by the material bed 17 are. Also, the one originating from the smaller particles Heat load is not so high because it cools down more quickly than the rough pieces. But only then do they reach the Conveying grate if it is already pre-cooled on the inclined surface 20 were.
- the underside of the Conveying grate is limited and is open to Gutbett 17 out. Its opening is through the front edge 31 of the inclined surface 20 limited, which is also indicated by the dash-dotted line Vertical line 32 determines the limit up to which the conveyor grate can be hit directly by the feed stream, that from the falling from the furnace and that from the Inclined surface 20 flowing down good.
- the height of the edge 31 therefore determines the size of the slope 33.
- the edge 31 should generally be a smaller one Height than the adjoining Gutbett 17. However there may be cases where this is not necessary is so that the surface 33 of the embankment 34 is not from the Edge 31 goes out, but lies lower. It is understood that the so-called edge 31 is not designed to be sharp-edged needs to be.
- the stationary grate part 6 is also located under the anteroom 30. It is also ventilated in the area of the anteroom 30, 3-6 schematically through channels 35 in the grate part 6 is indicated.
- the ventilated section of the stationary grate part 6 ends near the one in the rear (in the direction of conveyance)
- Boundary 36 of the vestibule 30 ventilated section 37 continued, which is convenient connects to the conveyor 8 without substantial distance. In this area there is also above the conveyor 8 a wall 38 closely adjoining it.
- the conveyor 8 enclosing ones, from the opposing ones Walls 37, 38 formed channel has a length, the least corresponds to the distance of the conveyor beams 9 in the conveying direction, so that there is always at least one bar 9 in it and the air outlet between the walls 37, 38 largely blocked.
- the facing surfaces of the walls 37, 38 therefore form together with that contained therein Bar 9 is a barrier against the escape or entry of air.
- the bed 34 located in the vestibule 30 is an intensive one Exposed to cooling. This cooling is more intense than it is outside the limit 32 in the area of the estate bed 17 would be because the amount of material exposed to the cooling air flow is smaller is. It can also be made special is intensively flowed through, for example, the cooling air flow effecting pressure difference is increased. This can the anteroom 30 above the embankment 34 with a special one Air vent 40 may be provided.
- the cooling is in the range of Embankment particularly effective because it is mainly is formed by smaller particles.
- the slope material 34 located in the vestibule 30 is indeed intermittently through the conveyor beams 9 taken away. While this is going through the anteroom move, but swells the material in front of and above them into the space that becomes free behind and is stored there on the stationary grate surface 7. Until the next conveyor beam appears, it has largely cooled down. Because he this good largely when it enters the free good bed 17 takes away and is enveloped by it, it remains there for the time being largely before the direct influence of the protected from hotter estates.
- the anteroom should be long enough in the conveying direction to the goods in it are sufficient for pre-cooling Grant residence time. These are usually a few minutes.
- the rule that the length of the vestibule has proven itself has proven itself corresponds to about half to twice the distance between the conveyor beams.
- the height of the edge 31 is expediently chosen so that the entire length of the vestibule 30 from the embankment 34 is taken. This is useful in view on economical use of space. It can also be avoided that cooling air through a free gap between the embankment and the trailing edge 36 of the vestibule escapes. Fig.
- Fig. 4 shows that the anteroom is not necessarily below an inclined surface 20 must be formed, but also formed, for example, in a vertical wall 42 can be. In this case, too, he is behind the Limit 32 of the immediate feed stream.
- the stationary one Grate part 6 has a wall 15 lying on the inside of conveyor 8 on. This forms on a section that is at least the distance corresponds to two conveyor beams 9, with one accordingly outside on the conveyor wall 51 a Sealing channel.
- the wall 51 also settles in the area 52 of the lower one Runs the conveyor away, with the conveyor beams on of the surface formed by the wall 52 lie or small Distance from this. This causes the conveyor forms a drag chain conveyor with the wall 52, is removed by the possible rust diarrhea.
- the wall 52 settles in the area of the deflection 12 continues as wall 53.
- the incline of the conveyor 8 in this deflection 12 begins to approach the vertical direction, will also be on the inside of the conveyor for one Limitation provided in the case shown by a deflection roller 54 is formed, but also formed by a wall can be, which corresponds to the wall 50 in the deflection 13. So becomes the rust diarrhea carried by the conveyor on the top of the stationary grate part 6 listed and arrives at easiest way back into the product stream.
