Abstract
The utility model relates to a composite ceramic hanging plate belonging to the technical field of cement production devices. The composite ceramic hanging plate aims to solve the problems that along with rapid development of the novel dry-process cement production technology in the cement industry in recent years, problems in the production process and the equipment appear, and particularly a metal hanging plate for an inner cylinder of a cement preheater has short service life and is easily abraded and damaged. The composite ceramic hanging plate adopts the technical scheme that a heat-resistant metal upper cross beam (4) and a heat-resistant metal lower cross beam (5) are respectively fixed on a hollow ceramic hanging plate (1); a heat-resistant metal U-shaped screw rod (3) respectively penetrates through the heat-resistant metal upper cross beam (4) and the heat-resistant metal lower cross beam (5); a heat-resistant metal screw cap (2) is screwed at the upper end of the heat-resistant metal U-shaped screw rod (3); and a circular hole (6) is arranged on the hollow ceramic plate (1). The composite ceramic hanging plate has the advantages that when the composite ceramic hanging plate is in use, the installation manner is more reasonable; the service life of the hanging plate is prolonged by 2-3 times; the design of a composite structure of the hanging plate is innovative; and the ceramic hollow plate can protect the heat-resistant steel against the erosion and the scour of corrosive gas.
Description
Technical field
The utility model relates to the cement production device technical field, is a kind of composite ceramics link plate more specifically.
Background technology
Along with new dry cement production technology in cement industry fast development in the last few years, the problem on production technology and the equipment also displays thereupon, particularly short and wear-out failure in the service life of cement preheater inner barrel metal link plate.From the generally reflection of cement production enterprise and investigation, find enterprise, in the new dry process production line the 4th of the kiln tail preheater system the, 5 grades of link plate formula inner cores, a lot of precious metals have been added in the chemical analysis of metal link plate, as nickel, chromium, alloying elements such as molybdenum, the iron ore market price that contains these elements is very high, the resistant and wear-resistant cast steel spare price of dvielement composition is very high thus, and casting finished products is through being damaged in various degree all behind 800-1000 ℃ of high-temperature region, the life cycle of link plate is 8-12 month, particularly reach as high as about 1050 ℃ with the final stage whirlwind tube temperature of the preheater of dore furnace, the life-span of inner core generally is no more than 1 year.Because ceramic material has a series of good properties such as high temperature resistant, wear-resistant, corrosion-resistant and in light weight, and advantages such as preparation cost is low, mature production technology, compare with heat resisting steel and to have long, advantage such as cost is low, installation is convenient of life-span, be widely used in 800-1200 ℃ the hot environment; But ceramic material has big gap with regard to its toughness, impact resistance than metal material, in the running under the hot environment, torsion or the unusual external force that produces because of fluctuations in wind speed in the preheating bucket very likely, and cause its damaged fracture to cause whole link plate system to come off.
Summary of the invention
For overcoming above-mentioned shortcoming, the purpose of this utility model is a kind of composite ceramics link plate of design, is hollow flat tube pottery and the compound link plate of heating resisting metal.Its technical scheme is: be fixed with heating resisting metal entablature and heating resisting metal sill on the ceramic hollow link plate respectively, heating resisting metal U type screw rod passes heating resisting metal entablature and heating resisting metal sill respectively, the heating resisting metal nut is screwed in the upper end place of heating resisting metal U type screw rod, has circular hole on the ceramic hollow plate.The advantage of this utility model is: this composite ceramics link plate reasonable in design, and the novelty that is skillfully constructed uses it to make mounting means more reasonable, and in 2～3 times of the service lifes of prolongation link plate, the composite structural design of link plate belongs to the innovation part; Ceramic hollow plate protection heat resisting steel is not subjected to the erosion of corrosive gas and washes away, and has guaranteed the service life of a whole set of composite ceramics link plate.The utility model composite ceramics link plate has solved the shortcoming that metal is not corrosion-resistant, wash away, and improved the operational reliability of ceramic hanging board, both possessed corrosion-resistant, the anti-characteristic of washing away of ceramic material, kept metal material good toughness and the good characteristics of torsional property again; Be easy to assembling, fixing, rational in infrastructure, it is good that the gasproof body washes away with the high-temperature corrosion resistance performance, is applicable to washing away and corrode operating mode of various corrosivity high-temperature gases, and preparation process is simple, and is easy to implement, suitable suitability for industrialized production.
Description of drawings
Fig. 1 is the utility model structural representation, and Fig. 2 is a cutaway view of the present utility model.In the accompanying drawing: 1, ceramic hollow link plate, 2, the heating resisting metal nut, 3, heating resisting metal U type screw rod, 4, the heating resisting metal entablature, 5, the heating resisting metal sill, 6, circular hole.
The specific embodiment
Be fixed with heating resisting metal entablature 4 and heating resisting metal sill 5 on the ceramic hollow link plate 1 respectively, heating resisting metal U type screw rod 3 passes heating resisting metal entablature 4 and heating resisting metal sill 5 respectively, heating resisting metal nut 2 is screwed in the upper end place of heating resisting metal U type screw rod 3, has circular hole 6 on the ceramic hollow link plate 1.This link plate is by the hollow link plate 1 of special cermacis; heating resisting metal entablature 4 and heating resisting metal sill 5 heat resisting steel assemblies are formed; heating resisting metal U type screw rod 3 passes ceramic hollow link plate 1; be suspended on the cement preheating bucket hook by heating resisting metal entablature 4 and heating resisting metal sill 5; ceramic hollow link plate 1 protection heat resisting steel is not subjected to the erosion of corrosive gas and washes away, and has guaranteed the service life of a whole set of composite ceramics link plate.Composite ceramics link plate described in the utility model is used the extruding forming method moulding, and heat resisting steel is selected special-purpose exotic material for use; The length of plate body 1 is 1200-3000mm, as 1200mm, 1350mm, 1580mm, 1850mm, 2000mm, 2200mm, 2500mm, 2800mm, 2900mm, 3000mm etc., the plate body cross dimensions can have 120 * 26mm, 150 * 28mm, 175 * 30mm, 200 * 26mm, 225 * 26mm or 260 * 35mm do not wait, hollow plate body inside is provided with reinforcement, cross section is rectangular flat round hole, 4 circular holes 6 of two rows are opened in plate body middle part and bottom, after every composite ceramics link plate hangs, to be connected to each other between link plate and the link plate with the special cermacis plate, keep the stability of whole link plate system.
