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 of unit; The 2nd, practical 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 break-down maintenance 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 practical life, is the technical problem that the manufacture of cement industry is paid close attention to.
Prior art has had employing with low cost, corrosion-resistant, wearability can better be made internal barrel of preheater cyclone barrel by heat resisting ceramic materials, but it is very big that the heat-stable ceramic post is produced difficulty, yield rate is low, therefore be made into ceramic component, be assembled into cylindrical inner core by ceramic component, the cylindrical inner core of assembling need satisfy firmly, simple installation, conditions such as thermosteresis is little, therefore need design the mode of connection between the lacing film well, as the patent No. is 200820099702.X, name is called the Chinese patent of " the high-temperature wearable inner core of preheater in the cement dry method production line ", its inner core is made of ceramic lacing film and skeleton, skeleton is the hollow cylindrical that ceramic web plate constitutes, the pottery lacing film is articulated in skeleton inner surface and outer surface, closely arranges internal surface and the outside surface that forms whirlwind tube inner core each other, and constitutes hollow structure.The assembly that constitutes skeleton is the top web plate of heat-resisting steel, middle connecting plate and bottom stiffening web.In the axial direction, the bottom of top web plate and a plurality of placed in-line middle connecting plate and bottom stiffening web constitute the chain shape.The top web plate links to each other with whirlwind tube permanent seat, and the middle part of top web plate and assembly web plate is provided with hangers and is used for hanger pottery lacing film.This assembling mode assembling procedure complexity owing to need the gravity of outside lacing film in the skeleton carrying, therefore needs high temperature steel as material simultaneously, and this makes the production cost of whirlwind tube inner core still occupy height, relies on the life-span with skeleton high temperature steel work-ing life; Because skeleton is a series-mode frame, when needing to adjust inner core height equidimension, needing thoroughly, the quantity of dismounting back minimizing middle connecting plate changes interior cylinder size, expend time in very much and manpower, influence enterprises production efficiency, therefore the assembling mode of ceramic whirlwind tube inner core awaits to improve to improve enterprises production efficiency.
The utility model content
The utility model provides a kind of internal barrel of preheater cyclone barrel that is applied to dry cement production line according to the demand that above-mentioned field exists, and production and mounting process are simple, can adjust size neatly and be satisfied with different production-scale demands.
