Description
Technical field
The utility model relates to a kind of air sealer, relates in particular to a kind of whirlwind gas lock air sealer.
Background technology
In a lot of fields, as industries such as grain, pharmacy, alloy powder, chemical industry and mineral products processing, all need material is pulverized, sometimes material need be pulverized very carefully, like this in the material grinding course of processing, often need remote wind-force to carry, between cyclone and discharge port, often need to be provided with air sealer.During air sealer work, the impeller-type rotor rotation in the air sealer is accepted material get off by the space between several pieces blades on the impeller-type rotor, deliver in the discharging opening then, and wind is intercepted, and can prevent dust dissipation everywhere like this, contaminated environment.Traditional air sealer mainly is made of housing and impeller-type rotor, in housing, be provided with rotor hole, the outer side edges of described impeller-type rotor blade and the parallel axes of rotor shaft, that is to say that impeller-type rotor when rotated, the running orbit of several pieces blade outer side edges is same osed top periphery, and the inner peripheral surface of rotor hole is parallel with aforesaid periphery.The air sealer of this structure in use has its defective, one is to use the life-span short, because rotor need rotate in rotor hole, the material that enters in the air sealer can have an abrasion action to the outer side edges and the rotor hole inwall of blade, softer material to they wearing and tearing may a little less than a bit, time one, long its worn-down amount was still very big, but the higher relatively material of hardness is just apparent in view to the wearing and tearing of blade outer side edges and rotor hole inwall, gap increase between blade outer side edges and the rotor inner wall just can not satisfy the operating needs of real work.Perhaps can remedy by the method for welding, but this technological requirement height, troublesome poeration.The 2nd, the Assembly And Disassembly inconvenience of rotor, the gap between blade outer side edges and the rotor hole inwall is very little, and rotor will be not easy to dock successfully inefficiency across two rotor holes on the housing when assembling; Air sealer is when work, fine-powder in the material can enter into the gap between blade and the rotor hole inwall, under the effect of friction heat, some material can be bonded on the blade, the purity of, depowering loss smooth and easy or institute's production material for the running that guarantees rotor, need in time clean rotor, require great effort very much when the structural relation between blade and the rotor hole inwall has caused the dismounting rotor.
Summary of the invention
For overcoming the defective of existing air sealer weak point in service life, Assembly And Disassembly trouble, the technical matters that the utility model need solve is: a kind of new structure whirlwind gas lock air sealer is provided, and it is simple in structure, reliable operation, long service life, Assembly And Disassembly convenient.
For solveing the technical problem, technical solution adopted in the utility model: a kind of whirlwind gas lock air sealer, comprise housing, be connected front and rear cover on the housing, with the joining rotor shaft of front and rear cover, described rotor shaft is provided with impeller-type rotor, described rotor is provided with several pieces blades, the outer side edges that it is characterized in that described blade constitutes an osed top conical surface, is provided with rotor hole in the described housing, and the tapering of described rotor hole inwall and the aforementioned conical surface match.The outer side edges of several pieces blades constitutes an osed top conical surface on the impeller-type rotor, and the tapering and the aforementioned conical surface of corresponding rotor hole inwall match, like this when causing both gaps to be strengthened because of the wearing and tearing of material between blade outer side edges and the rotor hole inwall, can adjust rotor position in the axial direction, thereby can adjust the gap between blade outer side edges and the rotor hole inwall, satisfying the requirement in the actual production, and then increased the service life of air sealer.In addition owing to be conical surface free-running fit between the two, to housing the time, being easy to make both to align, improved the assembling effect to rotor assembly, during dismounting as long as apply a bigger power when just beginning after, removing rotor fully will be very laborsaving.
As preferably, the outer side edges of described blade and the angle of described rotor axis are the 3--5 degree.
As preferably, the distance between the outer side edges of described blade and the inwall of described rotor chamber is the 0.1--0.2 millimeter.
As preferably, described rotor shaft is made of major axis and minor axis, described major axis and the mutual gap clamping of minor axis end, described front end cover is provided with front-end bearing pedestal, be provided with clutch shaft bearing in the described front-end bearing pedestal, be provided with the rotor shaft-linking sleeve in the described clutch shaft bearing, described major axis and the clamping mutually in the rotor shaft-linking sleeve of described minor axis; Have at interval on axially between described major axis and the described minor axis.
As preferably, the end of described minor axis is provided with groove, and the end of described major axis is provided with convex body, and described convex body is connected in the described groove.
As preferably, on described rear side housing, be provided with rear bearing block, be provided with second bearing in the described rear bearing block, described rotor shaft passes described second bearing cone, on rotor shaft, the both sides of described second bearing are respectively equipped with setting nut and fastening screw nut, be threaded between described setting nut and fastening screw nut and the rotor shaft.
Therefore, the beneficial effects of the utility model: tapered free-running fit of the outer circumference surface of impeller-type rotor and rotor hole inwall, the service life of having improved air sealer, and easy installation and removal; The angle of blade outer side edges and rotor axis, and the gap between blade outer side edges and the rotor hole inwall requires to have satisfied the real work requirement of air sealer; Rotor shaft is a split-type structural, and has between major axis and the minor axis at interval and can carry out axial location to rotor easily, and does not need adaptive adjustment is done in the position of the power input wheel on the rotor shaft, has simplified control step; , simple in structure, easy to process between the long and short axle with groove and the convex body form of clamping mutually; On rotor shaft, be provided with setting nut and fastening screw nut, can carry out axial location to rotor easily, make it satisfy actual job requirement.
