Description
Technical field
The present invention relates to a kind of blower fan, specifically a kind of mine ventilator.
Background technology
, as the capital equipment of air-supply, oxygen supplement, gas-removing in coal mine roadway, the noise producing when it normally runs is easy for mine ventilator
Make for a long time in the miner of underground work, tinnitus, dizziness, myasthenia of limbs and the symptom such as absent minded occur, to miner's body
Damage serious.In order to solve this problem, people typically can be respectively mounted deafener at the import and export of blower fan, by disappearing
The effect of sound device is reaching the purpose of sound-deadening and noise-reducing.But it simply carries out relevant treatment to the noise producing from blower fan, not from root
Solve noise in basis, any process is not carried out to the blower fan as noise source.Additionally, during actually used, being arranged on coal
The quantity of the blower fan in ore deposit tunnel is fewer, and the noise of generation is also less；And the installation number of blower fan is determined by the air feed distance of blower fan
Fixed, the air feed distance of blower fan is determined by the distinguished and admirable, air quantity of blower fan and the size of blast again；The distinguished and admirable resistance of existing blower fan is big, wind
Amount and air loss are larger, therefore a kind of normal noise that produces when running is less, distinguished and admirable resistance is little simultaneously, air quantity and air loss relatively
Little blower fan is current research direction.
Content of the invention
The problem existing for above-mentioned prior art, the present invention provides a kind of mine ventilator, when can not only reduce its normal operation
The noise producing, its distinguished and admirable resistance is little simultaneously, air quantity and air loss are less.
To achieve these goals, a kind of mine ventilator of the present invention, the motor including shell, being arranged on inside the shell and be arranged on electricity
The impeller at machine two ends, the motor housing on motor is fixedly connected with shell by connecting rod；Along rifling direction on the inwall of shell
Have an a plurality of groove I, the inwall between adjacent grooves I has least one set along rifling direction, by size cycle arrangement
Bloop, the track of every group of bloop circle center line connecting is parallel with the track of groove I.
Preferably, the cross section of described connecting rod is water-drop-shaped.
Preferably, the longitudinal section of the inwall of described shell is streamlined.
Preferably, the longitudinal section of the motor housing on described motor is streamlined.
Preferably, described motor housing has groove II along rifling direction, described groove II is consistent with the rotation direction of groove I.
Preferably, at least three, the blade on described impeller, adjacent blades）Between report to the leadship after accomplishing a task arrangement, projection in the axial direction no
Gap.
Preferably, the two ends of described motor housing are separately installed with the bearing of the concentric placement of rotating shaft with motor, and impeller passes through
Bearing is connected with motor housing.
Further, also include the Air Filter that is arranged on outer casing inner wall.
Compared with prior art, the present invention is by opening up fluted I along rifling direction on the inwall of blower housing, and recessed
The bloop of cycle arrangement by size is opened up along rifling on the inwall of groove I both sides, these bloops play the effect of sound-deadening and noise-reducing,
Thus eliminating noise and the energy of blower fan inwall generation, making blower fan produce noise in normal operation and reducing；Engagement groove I's
Setting, can not only merge the air-flow of friction speed, and the friction noise reducing the generation of friction speed air-flow is moreover it is possible to make flow spiral
Advance, decrease distinguished and admirable resistance, increase blast, improve wind speed so that the loss of air quantity and blast reduces.During use,
Deafener can be added again at its two ends again, relend the effect helping deafener so that final noise is less, reduce to greatest extent
The injury to miner for the noise.

Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, this mine ventilator, including shell 1, the motor 4 that is arranged in shell 1 and be arranged on motor 4
The impeller 2 at two ends, the motor housing 41 on motor 4 is fixedly connected with shell 1 by connecting rod 3；On the inwall 5 of shell 1
Have a plurality of groove I6 along rifling direction, the inwall 5 between adjacent grooves I6 has least one set along rifling direction,
The bloop 7 of cycle arrangement by size, the track of every group of bloop 7 circle center line connecting is parallel with the track of groove I6.
When blower fan normally runs, the bloop 7 on groove I6 both sides, blower fan inwall 5 has the effect of sound-deadening and noise-reducing, eliminates
Noise and energy that blower fan inwall produces, make blower fan produce noise in normal operation and reduce；Cooperation is alternate with bloop 7 to open
If groove I6, not only can merge the air-flow of friction speed, reduce the friction noise that friction speed air-flow produces moreover it is possible to make gas
Stream is threadingly advanced, and decreases distinguished and admirable resistance, increases blast, improves wind speed so that the loss of fan delivery and blast reduces.
And the loss of fan delivery and blast reduces the air feed distance that increased blower fan, decrease in air feed blower fan in the case of identical
Usage amount, and then decrease noise source, reduce noise.During use, deafener can be added again at its two ends again, by disappearing
The effect of sound device, so that final noise is less, reduces the injury to miner for the noise to greatest extent.
Preferably, when the cross section of described connecting rod 3 is water-drop-shaped, noise and the energy damage that it causes can be eliminated further
Lose, make the noise that whole blower fan itself produces less.
Preferably, when the longitudinal section of described shell 1 inwall 5 is streamlined, or the longitudinal section of described motor housing 41 is streamlined
When, the noise that these parts cause can not only be eliminated, make the noise that whole blower fan itself produces less；Can also reduce distinguished and admirable
Resistance, improves air quantity and blast, reduces its energy loss.
Preferably, as shown in figure 4, having groove II8, groove II8 and groove along rifling direction on described motor housing 41
The rotation direction of I6 is consistent to further reduce the Relative friction between both air-flows and resistance so that passing through both air-flow rotation directions unanimously,
Also reduce while reducing noise that air-flow is distinguished and admirable, air quantity and blast.
Because air-flow is when through impeller 2, have fraction through blade 21 between gap turn back round about, be unfavorable for air-flow
Make full use of.And in order to make full use of air-flow, as shown in figure 3, when at least three, blade 21 on impeller 2, phase
Overlap between adjacent blade 21, and its longitudinal overlap view gapless, arrangement of reporting to the leadship after accomplishing a task between adjacent blades 21, along axis side
To projection gapless it is possible to making air-flow further be utilized by way of reducing air-flow and turning back.
As shown in Fig. 2 the two ends of motor housing 41 are separately installed with the concentric bearing 43 placed of rotating shaft 42 with motor 4,
Impeller 2 is connected with motor housing 41 by bearing 43, and now, bearing 43 provides support force to impeller 2, and rotating shaft 42 is only given
Impeller 2 provides transmission couple of force, is not subject to the gravity of impeller 2, the side being only connected between impeller 2 and motor 4 by rotating shaft 42
Formula is compared, it can be avoided that the situation generation that rotating shaft 42 deforms because bearing the gravity of impeller 2.
As further improvement of the present invention, Air Filter also can be arranged on shell 1 inwall, for stoping dust and other impurities from entering
In bloop 7, prevent the situation leading to erasure effect to reduce because bloop 7 is blocked.
