The device disclosed by the invention realizes shock absorption and sound attenuation and eliminates noise produced by the spindle in rotation; a sound attenuation effect is achieved while cost is lowered; and triangular belt drive is adopted, so that part of moment is transferred to a contact surface of the triangular belt and the belt pulley when the device is started or high torque is produced.
Description
Technical field
The invention belongs to mechanical field, relate in particular to a kind of super-silent high pressure air intake device.
Background technique
The principle of suction fan is the mechanical energy relying on input, and raising gas pressure absorbs gas from intake grill and from exhaust outlet dispatch gas, is a kind of driven fluid machinery.Be widely used in each large fields such as factory, mine, tunnel, powder dust discharge.Traditional air intake device adopts motor and impeller direct-connected, is not with chassis base, is not with noise reduction casing, produce during operation high frequency intersect shake, noise is high, very easily motor damage when moment of torsion is excessive; The traditional noise-reduction method taked for noise adopts casting integrated casing, although casing thickeies can reduce a part of noise, casing and motor be not on same base, and cast iron casing is too heavy, high cost, and motor is also direct-connected, motor damage too when moment of torsion is excessive.
Summary of the invention
The invention provides a kind of super-silent high pressure air intake device, solve generation high frequency intersection vibrations when running in background technique, noise is high, cost is high, easily causes the problem of burn-down of electric motor when high pressure height moment of torsion runs.
Technological scheme of the present invention is achieved in that super-silent high pressure air intake device, comprise base, base is provided with motor, base is also provided with casing, exhaust outlet is provided with above casing, be provided with in casing every dish, by chassis cavity being divided into main shaft chamber and impeller cavity every dish, impeller cavity bottom is provided with intake grill, main shaft is provided with main shaft in chamber, front-end of spindle is provided with spindle pulley, spindle pulley is connected with the motor pulley on motor by v belt, rear-end of spindle is provided with impeller, impeller is positioned at impeller cavity, main shaft stage casing is provided with bearing support, bearing is equipped with in bearing support,
Preferably, described base bottom is provided with Rubber shock-absorbing pad.
The invention has the beneficial effects as follows: present invention achieves shock absorbing, noise reduction, the noise that when eliminating rotation, main shaft produces, reduce costs and play erasure effect simultaneously, adopt Belt Drive, during startup or when producing high moment of torsion, a part of moment is transferred on v belt and pulley contact face, release energy by skidding, stable drive, buffering absorbing, noise are low, and under normal service condition, motor can not damage.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Part illustrates: 1, exhaust outlet, 2, base, 3, spindle pulley, 4, motor pulley, 5, v belt, 6, casing, 7, main shaft, 8, bearing support, 9, bearing, 10, motor, 11, main shaft chamber, 12, every dish, 13, impeller cavity, 14, impeller, 15, intake grill, 16, Rubber shock-absorbing pad.
Embodiment
In order to better geographical and enforcement, below in conjunction with accompanying drawing, the invention will be further described: super-silent high pressure air intake device, comprise base 2, base 2 bottom is provided with Rubber shock-absorbing pad 16, base 2 is provided with motor 10, base 2 is also provided with casing 6, exhaust outlet 1 is provided with above casing 6, be provided with in casing 6 every dish 12, by chassis cavity being divided into main shaft chamber 11 and impeller cavity 13 every dish 12, impeller cavity 13 bottom is provided with intake grill 15, main shaft 7 is provided with in main shaft chamber 11, main shaft 7 front end is provided with spindle pulley 3, spindle pulley 3 is connected with the motor pulley 4 on motor 10 by v belt 5, main shaft 7 rear end is provided with impeller 14, impeller 14 is positioned at impeller cavity 13, main shaft 7 stage casing is provided with bearing support 8, bearing 9 is equipped with in bearing support 8.
Motor 10 is by v belt 5 drive main spindle 7 High Rotation Speed, the synchronized rotation of impeller 14 simultaneously, impeller 14 makes gas obtain kinetic energy, gas pours in impeller cavity 13 from intake grill 15, because impeller cavity 13 and main shaft chamber 11 are by being divided into two separate space every dish 12, gas only changes pressure energy at impeller cavity 13 into after diffusion flowing, and this part gas being enhanced pressure is discharged from exhaust outlet 1, thus completes air inducing, air draft process.Main shaft 7 is in casing 6, and noise during rotation is also wrapped in casing 6.
Motor of the present invention and casing are fixed on same base, and the vibrations that intersect during operation change into producing and resonate and be passed on base, be delivered on Rubber shock-absorbing pad again, realize shock absorbing, noise reduction by base; Main shaft is positioned at casing internal, the noise that when eliminating rotation, main shaft produces; Casing adopts welding casing, reduces costs and plays erasure effect simultaneously; Adopt Belt Drive, during startup or when producing high moment of torsion, a part of moment is transferred on v belt and pulley contact face, releases energy by skidding, and stable drive, to cushion absorbing, noise low, and under normal service condition, motor can not damage.
