Description
Technical field
The utility model belongs to Fan Equipment technical field, relates to a kind of high pressure multi-section type blower.
Background technique
High pressure blower, also be high pressure positive blower, its inside is provided with fan blade, in the time that fan blade rotates, due to the effect of centrifugal force, wind vane impels gas outwards motion forward, thereby form a series of spiral helicine motions, air between fan blade blade accelerates in the shape of a spiral rotation and the gas outside the pump housing is clamp-oned to side channel, after its approaching side passage, gas is compressed, then be returned to again between impeller blade and again accelerate to rotate, the degree that each impeller blade has increased compression and accelerated, along with the carrying out of rotation, the kinetic energy of gas increases, the gas pressure passing through along side canal is further increased, final gas is extruded blade and discharges the pump housing by outlet.Current high pressure blower, except impeller outer, does not have other moving parts, and the direct connecting motor of impeller, and small-sized being easy to carry about with one is widely used in cooling etc. the general suction air-supply of printing machinery, burning machine, woodworking machinery, dryer, incinerator, machinery.
As Chinese invention patent application (application number: 02822446.9) disclose a kind of high pressure blower, it comprises having a motor through axle wherein; The main impeller of being made by a kind of carbon fiber-based composite material, this impeller is arranged on the both sides of this motor and is directly installed on this axle of this motor; Surround the blower casing of this impeller; Center-aisle with a pressure opening of connection one blower casing and a negative pressure opening of another blower casing; The pedestal structure of this center-aisle and this high pressure blower is integral.Although this high pressure blower structure is comparatively compact, but because the fan blade in wind bucket is to be directly connected with the output shaft of motor, comparatively difficult when its assembling, and in use go wrong while needing repairing, the Placement dismounting between motor and wind bucket comparatively bothers.
Summary of the invention
There are the problems referred to above for existing technology in the utility model, has proposed a kind of high pressure multi-section type blower, and this high pressure multi-section type blower easy accessibility is convenient to maintenance, and usability is stable.
The purpose of this utility model can realize by following technical proposal: a kind of high pressure multi-section type blower, comprise base, on described base, be fixed with wind bucket, on wind bucket, be rotatably connected to rotating shaft, one end that wind bucket is inserted in described rotating shaft is fixed with fan blade, it is characterized in that, one end that wind bucket is stretched out in described rotating shaft is fixed with driven pulley, on described base, slidably connect motor, the output shaft of described motor parallels with rotating shaft, and the glide direction of motor and rotating shaft is axially perpendicular, on the output shaft of described motor, be fixed with drive pulley, described drive pulley is connected by belt with driven pulley, between described motor and base, be provided with and motor can be fixed on to the locating piece on base, described base is provided with can be by the tensioning mechanism of belt tension.
Base is bolted on worktable or ground, wind bucket and motor are set up in parallel respectively on base, and both connect by belt transmission, therefore when motor or wind bucket break down while needing repairing, without partition motor and wind bucket, unclamp locating piece, motor can relative to base aweather bucket move, belt is released, be convenient to dismounting and the replacing of belt, simultaneously also conveniently keep in repair targetedly, therefore maintain conveniently, these both also convenient in the time of production and assembly simultaneously; Fan blade during due to work in wind bucket is in High Rotation Speed, therefore tensioning mechanism is set on base, after motor is manually fixed on base by tensioning mechanism by belt tension, avoid the relative drive pulley of belt and driven pulley to skid, make service behaviour more stable.
In above-mentioned high pressure multi-section type blower, described locating piece comprises some holding down bolts, the bottom of described motor is fixed with the base plate of two strips, the length direction of described base plate is axial perpendicular to the output shaft of motor, on described base plate, offer along its length pilot hole, on described base, axially offer some bar holes along rotating shaft, described holding down bolt passes pilot hole and bar hole successively, and is bolted with setscrew nut at the external part of holding down bolt.Holding down bolt is located in pilot hole and bar hole simultaneously, and pilot hole and bar hole slip relatively in the time unclamping, slide and can regulate the distance between motor and wind bucket by the relative pilot hole of holding down bolt, slide and can regulate the degree of registration of drive pulley and driven pulley by the relative bar hole of holding down bolt.
In above-mentioned high pressure multi-section type blower, described tensioning mechanism comprises two Idle wheels, on described base, be vertically fixed with strut, the upper end of described strut is rotatably connected to dwang by coupling shaft, above-mentioned Idle wheel is rotatably connected on respectively the two ends of dwang, and the axial and rotating shaft of Idle wheel is axial consistent, on described coupling shaft, be arranged with a torsion spring, one end of described torsion spring is pressed on one end of dwang, the other end of torsion spring is pressed on the other end of dwang, under the effect of torsion spring, an Idle wheel is pressed on the upper side of belt, another Idle wheel is pressed on the downside of belt.After motor position regulates, be difficult to ensure that belt is by tensioning completely, therefore, under the effect of torsion spring, two Idle wheels compress respectively the upper and lower side of belt, and belt is tensioned.
In above-mentioned high pressure multi-section type blower, strut is passed in one end of described coupling shaft, and is vertically fixed with handle at the end that passes of coupling shaft.Handle with sleeve can overcome torsion spring torsion and make Idle wheel unclamp belt, is convenient to the adjusting of belt dismounting and motor position.
In above-mentioned high pressure multi-section type blower, the relative coupling shaft of described two Idle wheel is symmetrical arranged.Make Idle wheel more even to the active force of belt.
In above-mentioned high pressure multi-section type blower, described holding down bolt has four, and the pilot hole on described each base plate has two, and the upper bar hole of described base is four.Be that holding down bolt screws more steady that rear motor is fixed, and holding down bolt is stressed also more even, avoids motor oscillating to cause indivedual holding down bolts loosening.
Compared with prior art, this high pressure multi-section type blower has the following advantages:
1, owing to unclamping locating piece, motor can relative to base aweather bucket move, belt is released, therefore be convenient to dismounting and the replacing of belt, simultaneously also conveniently targetedly motor or wind bucket are keeped in repair, therefore maintain conveniently, these both also convenient in the time of production and assembly simultaneously.
2, due to tensioning mechanism being set on base, after motor is manually fixed on base by tensioning mechanism by belt tension, therefore can avoid the relative drive pulley of belt and driven pulley to skid, make service behaviour more stable.
3, because strut is passed in one end of coupling shaft, handle with sleeve can overcome torsion spring torsion and make Idle wheel unclamp belt, is therefore convenient to the adjusting of belt dismounting and motor position.
