In some embodiments, wear resistant heat preserving composite construction smoke pipe further includes tortoise plastron stratum reticulare, and the tortoise plastron stratum reticulare is located at Between insulating layer and wearing-proof refractory material layer or it is located in wearing-proof refractory material layer.Heat-insulation and heat-preservation buffer layer (2) has heat-insulated guarantor The double effects of mild buffering thermal shock stress not only improve the thermal efficiency, but also buffering thermal stress.
In some embodiments, the tortoise plastron stratum reticulare is welded and fixed with V-type rivet clasp steel nail.V-type rivet clasp steel nail (4) uses High-quality high temperature resistant stainless steel rivet clasp nail, has high temperature resistant, anticorrosive, stabilized structure.
In some embodiments, the tortoise plastron stratum reticulare is in the reticular structure of honeycomb type, the tortoise plastron stratum reticulare using steel or Stainless iron material.
In some embodiments, the V-type rivet clasp steel nail is set as multiple and in criss-cross evenly distributed.
According to another aspect of the present invention, a kind of production of high medium temperature wind and smoke pipeline of wear resistant heat preserving composite construction is provided Method includes the following steps:
S1, the inner wall that one end of V-type rivet clasp steel nail is welded and fixed to steel pipeline;
S2, heat-preservation cotton plate is pressed into the inner wall formation heat-insulation and heat-preservation buffer layer for being close to steel pipeline, and makes V-type rivet clasp steel Nail runs through insulating layer;
S3, wearing-proof refractory material layer are layed in heat-insulation and heat-preservation buffer-layer surface, and the other end of V-type rivet clasp steel nail runs through it In.
In some embodiments, the wearing-proof refractory material layer is constructed using high medium temperature abrasion-proof fire-resistant moldable refractory. Have the characteristics that intensity height, anti-strip, indeformable, alkali resistant corrode and thermal shock resistance is excellent, high temperature impact can be born, alkali resistant corrodes Performance is good, even wearing, and long service life has good workability, and constructing operation is convenient.
The step S3 further comprises following steps: first stirring evenly moldable pour into blender, is added mating Special curing agent, discharge after mixing evenly spare, smeared from bottom to top along cylinder insulation layer surface and ramming abrasion-proof and refractory can Plastics, then carry out surface floating, and natural curing 48h solidification forms firm smooth wearing-proof refractory material after toasted dehydration Layer (3).
The beneficial effects of the present invention are: for it is existing take that air hose liner is high using temperature, abrasion is big and alkali corrode it is serious Feature, the present invention change traditional air hose external thermal insulation structure, and insulating layer and wear-resistant material setting are being taken in air hose shell, substantially dropped The low heating temperature of steel casing, is in steel casing always in a lower temperature environments, reduces steel pipe body Deformation, has thoroughly prevented to burn down phenomenon, has improved its corrosion-resistant and wear-resistant degree, extend its service life, reduce into This.The present invention makes full use of the technical parameter of wear-resistant material and thermal insulation material, select suitable heat-resistance stainless steel rivet clasp structure into Row Optimal Structure Designing, can be in wear-resistant material and the guarantor for taking each position of air hose to select according to environmental parameter difference different-thickness respectively Adiabator and the structure reinforced using heat-resistance stainless steel, the present invention is by the way of taking air hose external thermal insulation structure to taking air hose Each position carries out modernization overlay, and using effect is significant at present, and former high temperature takes air hose liner to be easy to fall off and be easy the problem of burning down Thorough solution is obtained, medium temperature takes air hose external thermal insulation structure to be fully phased out.Through producing 5000 ton large-scale cements produced with the dry method daily The high medium temperature of kiln takes to be actually used on air hose, and significant effect, service life greatly improves, it is contemplated that up to 4~6 years, heat insulation effect was good It is good, production cost is significantly reduced, and be not susceptible to corrode or burn down, safety significantly improves.
