Abstract
The utility model relates to a coal delivering component of a pulverized coal burner with inner and outer surfaces provided with a wearable composite cladding material, which comprises a wearable sleeve I, a wearable sleeve II and a coal delivering pipe. The utility model is characterized in that the surface of each component which is easy to wear out is all provided with the wearable composite cladding material; the wearable composite cladding material is a composite cladding material combining the ceramic particle with the substrate metal. The utility model integrates the advantages of both the substrate metal and the ceramic particle, and is provided with not only the intensity, tenacity and magnetic property of the metal, but also the high rigidity, high wear resistance, high thermo tolerance and high corrosion resistance of the ceramics; the surface of the cladding material is provided with excellent over-all property of impulsion resistance and machinery washing resistance, rigid but not friable, which greatly improves the service life of the coal delivering component of the pulverized coal burner.
Description
Technical field
The utility model belongs to cement industry clinker burning field, particularly relates to coal burner that a kind of surfaces externally and internally the has wear resistant composite plating duct member of delivering coal.
Background technology
Coal burner is the important Thermal Equipment of cement plant calcination of cement clinker, and the stability of its serviceability and the length in service life directly influence stable, the realization of rotary kiln technical performance index of firing system thermal regulation and the output and the quality of clinker.And the result of use of burner and service life depend primarily on its main consumable accessory, i.e. the quality of the headset and the duct member anti-wear performance of delivering coal.At present the duct member of delivering coal of state's inner burner is because the restriction of its bulk and structure, though taked some abrasionproof treatment measures, effect is all undesirable.
Summary of the invention
The utility model provides a kind of good wear-corrosion resistance that has for solving the technical problem that exists in the known technology, the coal burner with wear resistant composite plating of the long service life duct member of delivering coal.
The utility model for the technical scheme that solves the technical problem that exists in the known technology and take is: the coal burner that a kind of surfaces externally and internally has the wear resistant composite plating duct member of delivering coal, form by wear-resistant sleeve one, wear-resistant sleeve two and the pipe of delivering coal, all have wear resistant composite plating on the surface easy to wear of described each part.
The utility model can also adopt following technical measures to realize:
The coal burner that a kind of surfaces externally and internally has the wear resistant composite plating duct member of delivering coal is characterized in that the inner surface of described wear-resistant sleeve one has wear resistant composite plating.
The coal burner that a kind of surfaces externally and internally has the wear resistant composite plating duct member of delivering coal is characterized in that the outer surface of described wear-resistant sleeve two has wear resistant composite plating.
The coal burner that a kind of surfaces externally and internally has the wear resistant composite plating duct member of delivering coal is characterized in that all inner surfaces of the described pipe of delivering coal all have wear resistant composite plating.
The coal burner that a kind of surfaces externally and internally has the wear resistant composite plating duct member of delivering coal is characterized in that described wear resistant composite plating is the composite deposite that ceramic particle combines with matrix metal.
Advantage and the good effect that the utlity model has are: owing to all have wear resistant composite plating on the surface easy to wear of each part of the utility model, and wear resistant composite plating is the ceramic particle composite deposite that combines with matrix metal, make it combine the advantage of matrix metal and ceramic particle, it had both possessed intensity, toughness and the magnetic of metal, the high rigidity, high-wearing feature, high-fire resistance and the highly corrosion resistant that have pottery again, the combination property of its coating surface shock resistance and anti-mechanical erosion is extremely strong, has crisp firmly and not characteristics.Because excellent surface quality and superpower surface bonding strength, its wearability is 23 times that 13 times of high chrome, 19 times of rich chromium cast iron, 3 times of the hard, wear-resistant steel alloy and nitrided surface are handled, improved coal burner greatly and delivered coal service life of duct member.
Description of drawings
Fig. 1 is the coal burner duct member structural representation of delivering coal.
Label among the figure is respectively: the 1st, and wear-resistant sleeve one, 2nd, wear-resistant sleeve two, 3rd, the pipe of delivering coal, the 4th, coal dust passage, the 5th, wear resistant composite plating.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
All inner surfaces that see also Fig. 1, the inner surface with wear-resistant sleeve () 1, the outer surface of wear-resistant sleeve (two) 2, the pipe 3 of delivering coal carry out surperficial hardened artiwear to be handled; make these surfaces all have wear resistant composite plating 5; thereby the formed coal dust passage 4 of above-mentioned piece surface is protected; when the high speed breeze airflow passes through coal dust passage 4; the part that forms the coal dust passage can not damage because of being subjected to washing away, thereby improves the service life of burner.
Claims (5)
1, the coal burner of a kind of surfaces externally and internally with wear resistant composite plating duct member of delivering coal is made up of wear-resistant sleeve one, wear-resistant sleeve two and the pipe of delivering coal, and it is characterized in that all having wear resistant composite plating on the surface easy to wear of described each part.
2, the coal burner of a kind of surfaces externally and internally according to claim 1 with wear resistant composite plating duct member of delivering coal is characterized in that the inner surface of described wear-resistant sleeve one has wear resistant composite plating.
3, the coal burner of a kind of surfaces externally and internally according to claim 1 with wear resistant composite plating duct member of delivering coal is characterized in that the outer surface of described wear-resistant sleeve two has wear resistant composite plating.
4, the coal burner of a kind of surfaces externally and internally according to claim 1 with wear resistant composite plating duct member of delivering coal is characterized in that all inner surfaces of the described pipe of delivering coal all have wear resistant composite plating.
5, the coal burner of a kind of surfaces externally and internally according to claim 1 with wear resistant composite plating duct member of delivering coal is characterized in that described wear resistant composite plating is the composite deposite that ceramic particle combines with matrix metal.
