Abstract
The utility model discloses a composite build up welding grinding roller for grinding equipment used for grinding pulverized coals in electric power, metallurgy, coals, iron steel, coal chemical industry and the like. The composite build up welding grinding roller comprises a grinding roller sleeve, a shaft sleeve and a grinding shaft, wherein, the grinding shaft is sheathed with the shaft sleeve; the grinding roller sleeve is fixed on the shaft sleeve; and a build up welding layer is arranged on the outer surface of a base layer of the grinding roller sleeve. The base layer is made of material with high ductility and good heat stability and is formed in one step in a casting manner, and the build up welding layer is made of the material with high abrasive resistance and high heat resistance and is arranged on the base layer through build up welding, so that a series of problems in a conventional grinding roller sleeve can be solved, and the composite build up welding grinding roller has the advantages of long service cycle, safety, reliability, low manufacture cost and the like; and the build up welding layer can be composited again through build up welding at the same time after being abraded, so that the requirements of the cyclic economy development can be conformed to.
Description
Technical field
The utility model relates to a kind of milling apparatus that coal dusts such as electric power, metallurgy, coal, iron and steel, Coal Chemical Industry grind usefulness that is used for, and especially relates to the mixing roll on the milling apparatus.
Background technology
All need to use coal in industries such as electric power, metallurgy, coal, iron and steel, Coal Chemical Industries, but these coals must grind to form the coal dust of certain granules size before use could be used, these producers all adopt milling apparatus that coal is ground for this reason.In milling apparatus, mixing roll is the critical piece that material is rolled pulverizing, it is formed by grinding roller shell, axle sleeve and grinding shaft etc., and grind roller shell as the critical component of bringing into play abrasive action, not only affect the height of output its service life, the safe operation of grinding roller shell is simultaneously determining the realization of enterprise's productivity effect especially.In process of lapping, be subjected to the relative extruding of mixing roll and mill and be ground into fine particle with various materials between mixing roll between mill.Grind in the process of roller shell conducting powder mill operation, not only need to overcome formation abrasion, cutting abrasion, cutter skiving and undermine fatigue wear, simultaneously because in the drying course of grinding material, also need bear-variations in temperature of 20-400 ℃, so high abrasion, high-fire resistance are the operations of mixing roll long-term safety, reduce the deciding factor of spare part cost.Because grinding roller shell is easily-consumed products, domestic for this reason many producers are in order to improve its service life, the numerous and confused alloy material of high abrasion that adopts is made, so just increased substantially the production cost that grinds roller shell, can only melt down casting processing again after grinding the roller shell wearing and tearing simultaneously, increase the production cost that uses producer so greatly, do not met " minimizing, utilize again, recycle, make again " development principle of recycling economy.
The utility model content
The utility model purpose is to provide a kind of built-up welding multiple grinding roller of new structure, grinding roller shell is to be made of basal layer and the overlay cladding of built-up welding on basal layer as aperture surface, basal layer is selected the mode one-shot forming of the material of high tenacity and Heat stability is good by casting for use, overlay cladding selects for use high abrasion and the built-up welding of high-fire resistance material on basal layer, thereby the existing existing a series of problems of roller shell of grinding have been solved, it is long to have life cycle, safe and reliable, advantages such as low cost of manufacture, built-up welding is compound once more after the overlay cladding wearing and tearing simultaneously, meets the requirement of recycling economy development.
The technical scheme that realizes the utility model purpose is:
A kind of built-up welding multiple grinding roller comprises and grinds roller shell, axle sleeve and grinding shaft that described axle sleeve is sleeved on the described grinding shaft, and the described roller shell that grinds is fixed on the described axle sleeve, it is characterized in that: at the described outer surface that grinds the basal layer of roller shell one overlay cladding is arranged.
The described roller shell that grinds is by cone voussoir and some equally distributed being bolted on the described axle sleeve.
The utility model compared with prior art has following advantage:
1. change original manufacture of grinding the roller shell integrally casting, adopt the method for cast welding combination, basal layer is selected the mode one-shot forming of the material of high tenacity and Heat stability is good by casting for use, overlay cladding selects for use high abrasion and the built-up welding of high-fire resistance material on basal layer, increases substantially the service life of grinding roller shell.
2. built-up welding is compound once more after the overlay cladding wearing and tearing, has reduced the production cost that uses producer, meets the requirement of recycling economy development.
3. adopt the basal layer of straight carbon steel or low-alloy steel material, can account for and grind more than 80% of roller shell weight, the overlay cladding that the special substance cost is high only accounts for 20% weight, all adopt the manufacture of high alloy material to compare with original roller shell that grinds, reduce the consumption of expensive material significantly, realized the remarkable decline of manufacturing cost.
4. grind roller shell by cone voussoir and some equally distributed being bolted on the described axle sleeve, the installation of conveniently grinding roller shell on the one hand, the concentricity of grinding roller shell and grinding shaft on the other hand by the assurance of cone voussoir.
Description of drawings
Fig. 1 is the structural representation of built-up welding multiple grinding roller described in the utility model
1. grind roller shell 2. overlay claddings 3. basal layers 4. cone voussoirs 5. bolts 6. axle sleeves 7. grinding shafts 8. mills
The specific embodiment
Following examples are used to illustrate the utility model, but are not used for limiting scope of the present utility model, and all technical schemes that are equal to also belong to category of the present utility model, and scope of patent protection of the present utility model should be limited by every claim.
As can be seen from Figure 1, a kind of built-up welding multiple grinding roller, comprise and grind roller shell 1, axle sleeve 6 and grinding shaft 7, described axle sleeve 6 is sleeved on the described grinding shaft 7, the described roller shell 1 that grinds is fixed on the described axle sleeve 6 by cone voussoir 4 and some equally distributed bolts 5, at the described outer surface that grinds the basal layer 3 of roller shell 1 one overlay cladding 2 is arranged.
In order to guarantee that mill 8 and the anti-wear performance that grinds roller shell 1 are consistent substantially, on mill 8 also built-up welding identical material is arranged overlay cladding 2 in process of lapping, the various materials between the overlay cladding 2 of mill 8 and grinding sleeve 1 are subjected to the relative extruding of grinding sleeve 1 and mill 8 and are ground into fine particle.
