Abstract
The utility model provides a prefabricated member for a laryngeal part of a cement-kiln used grate type cooler. The prefabricated member is assembled vertically and horizontally by two shapes of wear-resisting blocks; and the two shapes of wear-resisting blocks comprises a plurality of square shaped wear-resisting blocks (12) and corner shaped wear-resisting blocks (13). In the design of the prefabricated member, an arc groove is arranged on two adjacent side surfaces; an arc bulge is arranged on other two adjacent side surfaces; a metal anchor piece (10) is pre-buried on each wear-resisting block before the prefabrication of the wear-resisting blocks; the wear-resisting blocks are suspended on a joist steel (11) by the metal anchor piece (10); a heat preservation layer (14) is also arranged between the wear-resisting blocks and the joist steel (11); and labyrinth shaped expansion joints pieced together can prevent the smoke and the flame from springing out, thereby preventing the thermal insulation material and the anchor piece from the erosion of smoke effectively. The producing and the baking of the wear-resisting blocks are finished in a refractory material factory, therefore, no water is not contained; the wear-resisting blocks can be installed directly after being transported to the site and can be used directly after being installed on the site; therefore, the maintenance time can be saved and the problems that refractory castable at the laryngeal part of the grate type cooler is cracked, no expansion joints exist, the water content is high, the baking can not be implemented, the maintenance time is long, the wear is serious, the repair rate is high, the construction difficulty is large, the repair time is long, and the service life is short can be solved.
Description
Technical field
The utility model relates to a kind of cement kiln grate cooler inner lining structure, specifically, relates to the structural design category of a kind of cement kiln with grate cooler throat prefabricated component.
Background technology
Along with the continuous maturation and the national continuous lifting to the energy-saving and cost-reducing requirement of cement industry of cement using predecomposition technology, new dry process predecomposition cement kiln is as the rise of emerging rapidly in large numbersBamboo shoots after a spring rain.The new dry cement production technology economic indicator of China all reaches the level of production line of the same type in the world, has produced good economic benefit, social benefit and environmental benefit at home.In the technology of producing cement high speed development, the refractory material and the technology that matches are relatively backward, having a strong impact on the running rate and the output of cement kiln, " bottleneck effect " played in development to cement industry, and cement kiln serious wear also often occurs and burns phenomenon with grate cooler throat, so the refractory material at these positions becomes the link of the weakness in the cement kiln production process.
The cement kiln grate cooler is the equipment for the cooling down high-temperature clinker, it is by charging aperture (1), throat (2), top (3), side wall (4), grate plate (5), afterbody (6) six parts are formed (seeing Fig. 1, Fig. 2), charging aperture (1) is an infundibulate, and the top is the square mouth, and there is a charging slope below.The position that is attached thereto is throat (2), and shape is a ramp structure, and the throat outside is box hat (7), and inside is to be formed by the abrasion-proof and refractory pouring material cast-in-site, is an overall structure, do not stay and establish dilatation joint, and the water content height, the baking difficulty is big, and maintenance time is long.Throat closely links to each other with the top of back, there is side wall the both sides, top, be afterbody at last, afterbody is that foursquare air outlet (8) and discharging opening (9) are formed by connecting, air outlet (8) makes progress into 120 angles of spending with side wall (4), discharging opening (9) vertically downward, side wall bottom is for having the grate plate (5) of certain gradient.The high-temperature cement grog enters grate cooler charging aperture (1), to the afterbody discharging opening, finishes the clinker cooling procedure through grate plate.Useless flue gas is discharged through afterbody air outlet (8), and most cooling air enters miscellaneous equipment through throat, charging aperture.
Grate cooler throat abrasion-proof and refractory structure is to be formed by the abrasion-proof and refractory pouring material cast-in-site at present, be one fixing with metal anchorage (10), be suspended on the monoblock castable refractory on the I-steel (11), do not stay and establish dilatation joint, the water content height, can't toast, maintenance time is long, and service life is short.Because the high pressure wind-warm syndrome of cooling down high-temperature grog reaches 1200 ℃, and the flow velocity of high-temperature flue gas reaches more than the 25m/s, and dust contained flue gas concentration reaches 10Kg/Nm
3More than; cooling air enters miscellaneous equipment through throat, charging aperture; so explosion appears in the castable refractory at this position; crack extesion, is corroded very seriously at wearing and tearing, equipment often occurs and burns phenomenon; directly influence the normal operation of equipment; necessary shutdown maintenance has a strong impact on the normal operation of cement kiln, brings about great losses for cement manufacturing enterprise.
The purpose of this utility model provides a kind of cement kiln grate cooler throat prefabricated component, can effectively protect the throat of grate cooler, increases the service life, and shortens maintenance time, improves the running rate of equipment.
Summary of the invention
Cement kiln of the present utility model designs in the following manner with grate cooler throat preform structure:
Grate cooler throat prefabricated component mainly is the assembled in length and breadth (see figure 3) of wear-resistant block by several square type wear-resistant blocks (12) and (13) two kinds of shapes of turning type wear-resistant block, square type wear-resistant block (12) is foursquare square, upper and lower surface is smooth plane, two arc grooves parallel with top and bottom are arranged on adjacent two sides, on adjacent two sides two arc convex (see Fig. 5, Fig. 6, Fig. 7) parallel with top and bottom are arranged in addition; Turning type wear-resistant block (13) is the block with angle, on adjacent two sides arc groove is arranged, in addition on adjacent two sides arc convex (seeing Fig. 8, Fig. 9, Figure 10) is arranged, its arc groove and arc convex are identical with arc groove and arc convex on the square type wear-resistant block (12); During the prefabricated component assembly unit, the groove and the projection of the wear-resistant block of two kinds of shapes are stitched together, and keep the 5mm dilatation joint; Every wear-resistant block built-in metal anchoring piece (10) before prefabricated, wear-resistant block is suspended on the I-steel (11) through metal anchorage (10), between wear-resistant block and I-steel (11), also be provided with insulation layer (14), be installed with 5mm labyrinth shape dilatation joint (see figure 4) between the every wear-resistant block.
A kind of grate cooler throat prefabricated component that the utility model provides, because prefabricated component mainly is assembled by the design's turning type wear-resistant block (13) and square type wear-resistant block (12), on their adjacent in design two sides arc groove is arranged, on adjacent two sides arc convex is arranged in addition, the labyrinth shape dilatation joint that assembly unit connects can stop the string of flue gas and flame to go out, and has effectively stoped the erosion of flue gas to insulation material and anchoring piece; The manufacturing, toast all and finish of these wear-resistant blocks at refractory factory, water content not is transported to and on-the-spotly directly just can installs, directly come into operation after the on-the-spot installation, saved maintenance time, solved the castable refractory explosion of grate cooler throat, no dilatation joint, the water content height can't toast, maintenance time is long, serious wear, maintenance rate height, difficulty of construction is big, repair time is long, the problem that service life is short.
This prefabricated component need not the steel construction of equipment is transformed, and is simultaneously easy for installation simple, with low cost, but also can effectively improve antiwear property, and the protection device housings improves operation rate.
