Abstract
The utility model relates to a double shell axial-flow main ventilator for a mine, which is provided with a double-layer shell; an air cylinder of an outer shell is fixed and unchanged, and an internal cylinder of an inner shell can be made as the users' requirement. The rotary hub of the double shell axial-flow main ventilator for a mine is composed of two parts, and the external layer of a main wheel hub is inserted with a replaceable auxiliary wheel hub. The double shell axial-flow main ventilator for a mine has the advantages that when the working condition of a mine generates changing, as long as the internal cylinder of the inner shell is adjusted, and the proper auxiliary wheel hub is adopted, the specifications and the performance of the ventilator can be changed to be suitable for the requirement of the new working condition. The operating efficiency of the ventilator can be improved; the power consumption can be saved. Simultaneously, the process is simplified, and the cost is reduced.
Description
The utility model relates to a kind of double-shell mine axial flow main fan, belongs to mine ventilation equipment.
Mine main ventilator is the visual plant of mine, undertake the interior gas of thin well and be the vital task of personnel in the pit's oxygen supply, not only installed power is bigger, and long-term continual running, power consumption is considerable, reasonably design, manufacturing, selection and use mine main ventilator improve its operational efficiency, and very large economy meaning is arranged.Since mine newly-built, extend, reconstruct and renew, or because development and the deepening of producing, or owing to the reasons such as variation of geological condition, usually make the hindering and also have nothing in common with each other of each period (just, intermediary and later stages) of mine with air quantity, lane, this has just caused many operating points to mine main ventilator, because main fan before lacks necessary adjustability; Cause the equipment performance of these operating points and ventilator far apart, caused the reality that the ventilation equipment operational efficiency is low, energy consumption is big, wasted a large amount of electric energy.Main fan before can only be regulated fan blade established angle, stator blade established angle, revolution etc., all can not fundamentally solve the low problem of equipment operating efficiency.
The purpose of this utility model just provides a kind of novel fan that can adjust the change housing diameter and adjust the change hub ratio, can significantly change device characteristics, to adapt to the needs of mine working conditions change.
Double-shell mine axial flow main fan of the present utility model comprises driving mechanism, before, back poppet, the shell air duct, impeller, stator and core tube, it is characterized in that described impeller is by the main wheel hub, accessory whorl hub and fan blade are formed, fan blade is installed on the main wheel hub, the accessory whorl hub is made by sheet metal, be installed between fan blade and the main wheel hub, and be fixed on the main wheel hub, when the mine operating mode changes, when needing to adjust the hub ratio of blower fan, fill up vacancy between fan blade and the main wheel hub by the accessory whorl hub, before described, its interior circle size of back poppet is applicable to a kind of minimum accessory whorl hub of specification, its excircle dimension is applicable to the maximum impeller of this specification, described shell air duct is also pressed the maximum fan blade manufacturing of this specification, shell air duct inside studs with the inner casing air duct that disconnectable sheet metal is made, impeller turns round in the inner casing air duct, inner casing air duct two ends have conically shaped and shell air duct to advance, the outlet switching, add the flow apron that two ends and core tube are connected mutually on the runner between inner casing air duct and the accessory whorl hub, pass through smoothly in order to distinguished and admirable, when the fan blade diameter was adjusted according to the mine operating mode, the inner casing air duct was adjusted replacing thereupon.
The utility model has the advantages that in mine operating mode and fan performance and take place to depart from more greatly, when the operational efficiency of blower fan is reduced significantly, as long as go out required housing diameter and hub diameter according to new condition calculating, suitably strengthen or dwindle the inner casing air duct of blower fan, reselect suitable accessory whorl hub to satisfy the requirement of hub ratio, just can be fit to new working condition requirement fully, the optimum of fan performance is consistent with the mine operating mode, reach high-efficient operation, energy saving.Inner casing air duct and accessory whorl hub all are simple and easy that is made by sheet metal, and preparation process is simple, and is with low cost.Blower fan manufactory is satisfying under the prerequisite of customer requirements, can simplify description, unified part kind, simplified manufacturing technique, reduces product cost, and using for manufacturing, type selecting and the scene of mine ventilation machine provides convenience.
Fig. 1 is a general structure schematic representation of the present utility model.
Fig. 2-the 7th, impeller of the present utility model and support, inner casing air duct collocation schematic representation.
Fig. 8, the 9th, blade wheel structure schematic representation of the present utility model.
Embodiment: referring to Fig. 1-9, double-shell mine axial flow main fan of the present utility model comprises driving mechanism 1, before, back poppet 2, core tube 3, inner casing air duct 4, shell air duct 5, stator 6, impeller 7 and flow apron 8, its support specification is that to be equivalent to old diameter be 1.8 meters blower fan to #18(), circle radius is 0.45 meter in the front and back support 2, exradius is 1.1 meters, promptly being suitable for the blower fan maximum diameter is 2.2 meters, minimum hub ratio is 0.4/1.1=0.41, shell air duct 5 and core tube 3 are all by the supporting making of above-mentioned size, the adjustable range of this blower fan is: 1.2 meters-2.2 meters of air duct diameters, hub ratio 0.41-0.75, impeller 7 is by main wheel hub 11, accessory whorl hub 10 and fan blade 9 are formed, fan blade 9 is fixed on the main wheel hub 11 by the screw thread of fan blade bar end, accessory whorl hub 10 is a sheet metal spare, be installed between fan blade 9 and the main wheel hub 11, fill up because hub ratio changes the fan blade 9 cause and the vacancy between the main wheel hub 10, accessory whorl hub 10 by screw on main wheel hub 11.Blower fan is made the package size that factory can select inner casing air duct 4 and accessory whorl hub 10 by customer requirements, to satisfy the requirement of user to air quantity, blast, efficient.Concerning the user, if the mine working conditions change, the situation that the blower fan that is using does not match also can suitably be adjusted inner casing air duct 4 or change suitable accessory whorl hub 10.Fig. 2, the 3rd, fan blade 9 vary in diameter are only adjusted inner casing air duct 4 sizes, and both are complementary; Fig. 4, the 5th, hub diameter changes, and only changes suitable accessory whorl hub 10; Fig. 6, the 7th, fan blade 9, hub diameter change simultaneously, then should adjust inner casing air duct 4, change suitable accessory whorl hub 10 again.Inner casing air duct 4 and accessory whorl hub 10 all are sheet metal spares, make simple, easy for installation.Add flow apron 8 on the runner between inner casing air duct 4 and the accessory whorl hub 10, flow apron 8 two ends are connected with core tube 3.
For the mine that cooperates different scales needs, the double-shell mine axial flow ventilator can be divided into miniature, small-sized, medium-sized, large-scale four seat No., sees following table for details:
