The utility model discloses a make simple structure, low cost, simple to operate, long service life is applied to in technical field such as mine, metallurgy, chemical industry.
Description
Technical field
The utility model relates in the industries such as mine, metallurgy, chemical industry for carrying out a kind of spiral vertical grinder cylindrical shell grid liner plate of wet method fine grinding, superfine grinding to material.
Background technology
In mine industry, along with industrial mineral deposit is to poor thin assorted trend transfer, the fineness of ore grinding becomes one of key factor determining the grade of ore.Along with high grade ore exploitation totally, the exploitation of lean ore is Main way domestic at present.Several hundred million, billions of tonnes lean ore is had to need to realize monomer dissociation by fine grinding, Ultrafine Grinding every year.Under the overall background of national energy-saving reduction of discharging, environmental protection, the mode as how economic realizes the monomer dissociation of material, is a difficult problem of pendulum in face of mineral processing practitioner.In addition, the utilization of regrinding of the mine tailing month after month amassed in year will be also the point of economic increase of resource rearrangement.
At present, in the industries such as mine, metallurgy, chemical industry for carrying out wet method fine grinding to material, the equipment of superfine grinding adopts spiral vertical grinder.It is mainly used in following occasion: 1) primary grinding: for replacing the ball mill in tradition " old three sections+ball milling flow process ", also can substitute the ball mill in SAB flow process; 2) concentrate regrinding: that can grind is thinner, realizes higher monomer dissociation granularity, by improving concentrate grade after flotation; 3) tailings glass: can extract utility, turns waste into wealth the mine tailing being rich in valuable mineral in older for past technique.
The structure of spiral vertical grinder cylindrical shell is tubular welding cylindrical body, inner filling tens tons is to hundreds of tons of steel balls, after starter motor, steel ball and material are under the drive of helical axis, under being subject to the comprehensive function of self gravitation, spiral centrifugal power, liquid buoyancy and liquid rising drag, do multidimensional shuttling movement and spinning motion, therefore inner barrel liner plate is subject to very test, the subject matter of current existence is: traditional spiral vertical grinder shell liner adopts magnetic liner plate, liner plate weight is large, cost is high, and the life-span is short.Therefore, develop a kind of spiral vertical grinder cylindrical shell grid liner plate is new problem anxious to be resolved always.
Summary of the invention
The purpose of this utility model is to provide a kind of spiral vertical grinder cylindrical shell grid liner plate; this utility model is applied on spiral vertical grinder; play the effect of protection spiral vertical grinder cylindrical shell, when the apparatus is in operation, the steel ball of device interior and material are filled within grid; formed from wearing layer; can effectively protect cylindrical shell from wearing and tearing, there is manufacturing structure simple, with low cost; easy for installation, the features such as long service life.
The purpose of this utility model is achieved in that a kind of spiral vertical grinder cylindrical shell grid liner plate, comprise cylindrical shell, grid liner plate, bolt, packing ring, nut, the rubber lining with adpting flange, the packing ring of stainless steel is equipped with on the connecting hole surface of the grid liner plate of welding, by high strength full thread stainless steel bolt, two grid liner plates are connected on the cylindrical shell with adpting flange, are serving as a contrast with the cylindrical shell of adpting flange being arranged rubber and fixing with double nut;
Described grid liner plate stainless-steel sheet welds, and weld seam adopts 6mm continuous fillet weld;
Gap between described grid liner plate and cylindrical shell and adpting flange thereof is less than 1mm.
Main points of the present utility model are its structure.Its operation principle is, adopts stainless-steel sheet to be welded to form lattice structure, is bolted on the adpting flange of inner barrel by grid liner plate block-by-block.When the apparatus is in operation, the steel ball of inner barrel and material are filled into grid liner plate inside and are formed from wearing layer, and play the effect of protection cylindrical shell, effective extending body life time, and install simple and convenient, cost is low.
Compared with prior art, have manufacturing structure simple, with low cost, easy for installation, the advantages such as long service life, will be widely used in the technical fields such as mine, metallurgy, chemical industry a kind of spiral vertical grinder cylindrical shell grid liner plate.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and enforcement, the utility model is described in detail.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the I portion enlarged drawing of Fig. 1.
Fig. 3 is the structural representation of the utility model grid liner plate.
Detailed description of the invention
With reference to accompanying drawing, a kind of spiral vertical grinder cylindrical shell grid liner plate, comprise cylindrical shell 1, grid liner plate 2, bolt 3, packing ring 4, nut 5, the rubber lining 6 with adpting flange, the packing ring 4 of stainless steel is equipped with on the connecting hole surface of the grid liner plate 2 of welding, by high strength full thread stainless steel bolt 3, two grid liner plates 2 being connected on the cylindrical shell 1 with adpting flange, also fixing with double nut 5 with the cylindrical shell 1 of adpting flange being arranged rubber lining 6.
The stainless-steel sheet welding of described grid liner plate 2, weld seam adopts 6mm continuous fillet weld.
Gap between described grid liner plate 2 and cylindrical shell and adpting flange 1 thereof is less than 1mm.
The utility model is described in further detail below in conjunction with embodiment:
Make lattice-shaped with stainless-steel sheet by the mode of welding, weld seam adopts 6mm continuous fillet weld.Postwelding processes connecting hole on grid liner plate 2, and for ensureing assembly precision, the position degree of its connecting hole is no more than 1mm.The packing ring 4 of stainless steel is lined with at grid liner plate 2 hole surface, to ensure fastening stationarity, by high strength full thread stainless steel bolt 3, two grid liner plates 2 are connected on the cylindrical shell 1 with adpting flange, and apply wear-resisting, anti-corrosive rubber lining 6 at cylindrical shell and flange surface thereof in advance.For preventing loosening, fastening with double nut 5.Fastening rear inspection grid liner plate 2 and with adpting flange cylindrical shell 1 between gap, guarantee that gap is less than 1mm.
When installing grid liner plate 2, because grid liner plate 2 is weldment, during welding, there is welding deformation unavoidably, therefore when assembling with the cylindrical shell 1 with adpting flange, because preset clearance is less, with hand hammer, grid liner plate 2 need be rapped between two flanges, aim at joint hole more afterwards.Guarantee grid liner plate 2 and with adpting flange cylindrical shell 1 between gap be less than 1mm, if be greater than 1mm, pad can be looked at the construction field (site) by gap jam-pack.For preventing the later stage from loosening together with pad can spot weld with grid liner plate 2 after jam-pack.Subsequently, two grid liner plates 2 are linked up by packing ring 4, bolt 3 and nut 5.First should tighten lower nut 5 by 80% moment during connection, then tighten top nut 5 by 100% moment.So far, a pair grid liner plate 2 installs.
