Description
Technical field
The utility model relates to a kind of preheater windspout barrel, is the internal barrel of preheater cyclone barrel that is applied to new type nonaqueous cement production line specifically.
Background technology
For a long time, applied internal barrel of preheater cyclone barrel in the domestic and international dry cement production line, material is based on the kuromore steel, its outstanding shortcoming is present in two aspects: the one, and the price comparison costliness of steel, per ton usually all more than 100,000 yuan, produce an internal barrel of preheater cyclone barrel cost like this and will reach hundreds of thousands unit; The 2nd, physical life is shorter, and the acid-alkali-corrosive-resisting poor-performing of steel alloy on average has only 10-14 month in the normal following life-span of state.Change inner core based on this shut-down (breakdown) mainteance that causes, had a strong impact on the production time of enterprise, caused burden for enterprise's production cost.How to make a kind of high strength that has, anticorrosive wear-resistant decreases the inner core of performance to substitute existing steel alloy, controls production cost simultaneously, improves physical life, is the technical problem that the manufacture of cement industry is paid close attention to.
The existing employing of prior art is with low cost, corrosion-resistant, mar proof can better be made internal barrel of preheater cyclone barrel by ceramic component, put down in writing a kind of " full internal barrel of ceramic pre-heater " as Chinese patent 200820188205.7, its wear-resistant ceramic assembly comprises the wear-resistant ceramic post and the arced ceramic connecting plate of splicing assembling, the wear-resistant ceramic post splices mutually, the splicing side is by alphabetical docking port splicing, wear-resistant ceramic post upper and lower side and connecting plate are respectively equipped with connector, connect by screw bolt and nut.This connecting method is simple in structure, splicing is convenient, but because inner core only has one deck ceramics pole, ceramics pole length is long, and the refractory ceramics difficulty of processing is big, cause cost higher, simultaneously, because expanding with heat and contract with cold under the temperature difference, interior outer arcuate connecting plate and ceramics pole occur loosening after producing distortion, can't closely connect, service life is not long.Disclose in the Chinese invention patent 200810050022.3 " ceramic hanging board that a kind of internal barrel of preheater cyclone barrel is used and method of attachment " and a kind ofly spliced with the little ceramic hanging board of size, the difficulty of processing of little ceramic hanging board reduces, but this ceramic hanging board complex structure, and splicing is complicated, also exists because the danger of expanding with heat and contract with cold and causing pottery to burst apart simultaneously.
