Definitions

  • the conveying speed of the material bed is determined by the grain size distribution influenced in the estate bed.
  • the grate has a higher proportion of fines than the middle one Encountered area. This is due to the fact that the outflow of material from the thicker middle one Demix the area of the grate to the sides takes place, the proportion of coarse fractions in the middle and the proportion of finer fractions in the side areas favored.
  • the furnace discharge is also across the width of the Does not rust evenly. On one side and in the middle becomes more coarse material, on the other hand more fine Material dropped.
  • the good speed can be undesirably high Accept values so that the cooling effect is no longer sufficient ("Red River").
  • the invention is therefore based on the object of a method to distribute the goods over the width of a conveyor grate to create, on which the Gutbett initially in a first width section a greater thickness than in at least a second, adjacent latitude section. It it is also based on the task of performing one of the method suitable sliding grate to accomplish.
  • the solution according to the invention consists in the features of Claims 1 and 4 and preferably the features of the subclaims.
  • the method according to the invention is characterized in that that the estate bed in the first breadth section in which it was initially thicker than the second, neighboring latitude section is still dammed up. Thereby the difference in the bed thickness is increased. This in turn has the consequence that the good to the side Drain from the first, more populated section to the second latitude section.
  • This method is suitable for sliding gratings because they are cause constant movement within the estate and hence the flow of the goods from the first to the second Breadth section can also take place if the Angle of repose is not exceeded.
  • the goods are stowed in the first breadth section in that the conveyor grate therein with less Conveying speed operated as in the second width section becomes.
  • the good in the first breadth section be braked in places by appropriate obstacles be provided, which is the conveying movement of the good inhibit. These can span the entire length of these sections be more or less distributed.
  • this braking mainly takes place in the initial section of the first breadth section, where anyway by the dropping of the thickness difference between this latitude section and the neighboring ones Width sections is largest.
  • the Conveying action of the grate on the material bed begins in the so-called first latitude section later than in this one neighboring, less populated, so-called second latitude areas.
  • first and at least a second breadth section is spoken in primarily on an arrangement of three arranged side by side Sections thought, the middle of which is the initial has stronger occupancy, while the two outer weaker are occupied.
  • the principle of the invention par excellence on every pairing one stronger and one weaker occupied width section can be read. If, for example in an arrangement of five next to each other Width sections the middle the strongest initial occupancy experienced, this is the first breadth section in relation to the sections immediately adjacent to it. These can, if initially or during the distribution process are occupied more than the outermost sections again as the first broad sections in relation to those on the very outside horizontal sections are considered.
  • the distribution method according to the invention Division of the grate into several width sections with different Conveyor speed only in a relative short section of the grate is provided, which is expedient is located at or immediately after the posting point and because of its function here as a compensation section referred to as.
  • first width section with a lower feed rate than in at least one neighboring one initially a smaller thickness of the refrigerated goods bed, second width section, so the difference in thickness of the refrigerated goods bed strengthened and consequently more good from the more heavily occupied Broad section into the neighboring, faster-conveying Drain the section with a lower material bed thickness.
  • You control this so that at the end of the compensation section on this Result in the same mass flows in all sections and one then leads this to a subsequent section of grate, the same conveying speed of the Guts, you get one across the entire grate width constant bed thickness. Therefore, the Feed speed of the neighboring latitudes in the compensation section depending on the relative thickness of their Regulated refrigerated goods bed.
  • the material bed thickness may be appropriate to keep it a little lower in the side areas than in the middle area, at over the grate width uniform cooling air pressure the higher air resistance in the areas lower average Grain to take into account. If you look at the side areas with a higher cooling air pressure than that middle range, however, it may be appropriate to Side areas with a slightly greater bed thickness than in the middle Operate because of the smaller grain size in the side areas better conditions for heat transfer delivers. As always, the distribution of the bed thickness in the main part of the cooler the invention provides a suitable means for this.
  • a sliding grate is suitable for carrying out the method, the one in the compensating section arranged side by side Wide sections with separate drive means for each other has a different feed rate, which in the second breadth section (or the second breadth sections) is larger or can be set larger than in the first.
  • the movement speed is below the feed speed the cause of the conveying movement of the good Understand rust organs. There is a difference on the conveying speed of the good bed.
  • Under separate Feed means are therefore to be understood as those allow the feed rate of the latitude sections different and preferably independent of each other adjust.
  • first breadth section an additional number of unmoved as an obstacle to funding Contain grate plates, for example as so-called Bridging plates also in the range of moving rows Grate plates can be provided. You will be expedient over the length of the first breadth section distributed in which a congestion effect is desired.
  • the first breadth section a larger number or Total length of such unmoving rows of grate plates before, during one in the neighboring, less populated, second Width sections a smaller number or total length of the provides unmoved rows of grate plates and the moving rows of grate plates lets start earlier.
  • each of the neighboring sections can be set independently of the others or adjustable; however, it may be sufficient if only whose relationship to one another is changeable. To it may suffice if, for example, with an arrangement only three width sections arranged side by side the feed rate in the middle area or the Feed speeds in the side areas can be changed are.
  • the regulation of the feed speeds in the compensation section expediently takes place depending on the Gutbed height in the individual sections. Instead, can also the bed height in the corresponding width sections Width ranges of the following cooler section used will.
  • the length of the compensation section can be small in relation to the total length of the grate. It is dimensioned such that the desired compensation can be achieved. A bigger one Length than twice the grate width is usually not required. As a rule, a length that is less is sufficient is than the simple grate width. Under the length of the compensation section is the length of the longest latitude section of the compensation section to understand that with a feed speed deviating from the following grate section is operable.
  • the lateral good bed compensation in the compensation section can are promoted in that the compensation section greater inclination in the conveying direction than the following grate section is awarded.
  • the inclination of the Compensating section in the order of 8-15 °, while the slope in the following section only in is on the order of 1-7 °, preferably 3-5 °.
  • the inclination can be 0 °.
  • the width of the sections is according to the distribution the bed thickness immediately afterwards to the application area dimensioned. If three sections are provided, have the latitude sections to the side of the middle section expediently half to full width of the middle Section.
  • the compensation section in the hot area of the radiator lies and the differences in the grating due to the Invention will be temporarily strengthened in this area, it is expedient to ventilate the conditions in the adapt to different feed areas and consequently the separately drivable sections can also be ventilated separately close.
  • the cooling grate of a clinker cooler shown in Fig. 1 consists of three sections, namely the inlet area 1 and two downstream sections 2 and 3.
  • the thing to be cooled Well falls out of the upstream rotary kiln mainly in the area 4 hatched in FIG the cooler and then spreads across its width.
  • sections 2 and 3 the main part of the cooler form, it is carried out conventionally, namely from changing Cross rows of fixed and 5 in the conveying direction retracted grate plates.
  • Section 2 is weak around 3 ° inclined in the conveying direction.
  • Section 3 is horizontal.
  • sections 2 and 3 is the feed rate of the grate plates constant over the width. That on it lying good bed can be in its different types Wide areas have different conveyor speeds.
  • the inlet area 1 is also made of transverse Grid plate rows built. Outside of those explained later stationary areas it is composed of three broad sections, namely from a middle section 6 and the side sections 7 and 8, each also from transverse rows are formed by rust plates, which are alternating and moving back and forth in the direction of conveyance indicated by arrows are driven. It goes without saying that one other number of width sections can be chosen, for example two, four or five.
  • the structure of the inlet area 1 is shown in more detail from Fig. 2. Individual grate plate fields are through strong border set off from other fields. In the fields 10, 11, 12 are only stationary grate plates intended. A bed of refrigerated goods is deposited on them, which directly prevents the rust from overheating and wear and tear Protects goods coming from the oven.
  • the fields 6, 7 and 8 alternate between fixed and moving back and forth rows of grate plates, wherein the first row of grate plates following fields 10-12 is a moving one. They are independent of the grate plates the other fields and the following section 2 driven.
  • the middle section 6 has in the illustrated Example the width of six grate plates while the outside lying sections 7 and 8 each five grate widths include. Sections 7 and 8 are ten grate plates long. The length of the compensation section thus determined is to the ample half the width of each of the three sections. In the middle section 6 are about Length distributed instead of plates in moving rows of grate plates some stationary, hatched Bridging plates 9 are provided.
  • the fixed rows of grate plates are at rest on transverse grate plate carriers 14, which in turn rest on edge supports 15 and longitudinal bars 16.
  • the grate plate carrier 14 are as air ducts to those with them air-ducted grate plates are formed. she are in air-separated support sections 14a, 14b and 14c divided so that the associated Grate plate groups supplied with air independently of one another can be.
  • the longitudinal bars 16 and possibly the edge beams 15 are as air duct for supplying the grate plate support sections educated.
  • the longitudinal bars 16 are ventilation divided into halves 16a and 16b, each adjacent sections 14a, 14b and 14c of the grate plate carrier assigned.
  • the middle sections 14b of the 5 are fixed by a Channel 13 forth via branches and the assigned to them Longitudinal beam halves 16a are supplied with cooling air. Corresponding become the outer grate girder sections 14a and 14c from cooling air ducts 17 and 18 via them associated longitudinal beam halves 16b and the edge supports 15 supplied with cooling air.
  • the movable grate plates rest on each other mechanically separate grate support sections 20a, 20b and 20c, each carried over consoles 21 by longitudinal spars 22a, 22b and 22c are, in turn, longitudinally movable in a known manner rest on bearings 23 and by means of hydraulic drives 24 are pushed back and forth in the longitudinal direction of the plate can. This creates the feed motion.
  • the grate plate supports 20a, 20b and 20c, the brackets 21 and the longitudinal spars 22 are used to supply cooling air to them Grate plate groups designed to carry cooling air.
  • the Longitudinal bars 22b of the movable rows of grate plates in the middle Section 6 are (see FIG. 5) from the cooling air duct 13 supplied with cooling air via branches 26 which are tolerant of movement.
  • the same applies to the grate plates of sections 7 and 8 respectively these sections can be independent as well as their frequency of movement be set by the other sections.
  • Cooling air is also supplied to fields 10, 11 and 12 provided, and that can be seen in Fig. 3 cooling air channels 29, 30 assigned to these fields. Still others Cooling air supply devices are for the radiator sections 2 and 3 or, if desired, for individual fields provided within these sections. To avoid a too many parameters to be controlled may be appropriate the cooling air supply to the individual fields after a one-off, appropriate setting to leave constant and only still regulate their feed rate.
  • the inclination of the grate section shown in FIG. 3 in the conveying direction is 10 °.
  • the configuration of the compensation section given in this example allows the cooler width to be increased by about 25% for a given cooler performance. This means that the thrust frequency in the cooler sections 2 and 3 can be reduced by approximately 25%.
  • the cooler frequency due to the synergism between the equalizer of the Gutbettdicke one hand, and the stronger as compared with conventional coolers inclination can be further decreased, namely of the order of 20 min -1 to 10 min -1 under.
  • a typical example has a shear rate of 5 min -1 and in the side sections such 7-8min of -1 in the center section of the inlet portion. This significantly reduces plate wear in all sections.
