Abstract
The utility model provides a centrifugal fan is used in mine, includes impeller, air intake, boss rod and casing, and casing one side is provided with the air intake, and the casing opposite side is provided with the impeller, and the impeller lower extreme is provided with the belt pulley, and belt pulley one side is provided with the boss rod, and boss rod one side is provided with the bearing, and the bearing lower extreme is provided with the bearing bracket, and the casing lower extreme is provided with the air outlet. Beneficial effect lies in: the casing adopts whole form, and intensity is big, the impeller through move, the static balance rectifies, the air is functional, whole is made to the air intake, be curve shape with axial direction parallel's cross -section, enables gas and get into the impeller smoothly, and lose lessly, efficient, the consumption is little, smooth operation, the noise is low, the structure is perfect, is convenient for maintain and the dismouting that the amount of wind is big, the wind pressure is stably, and is applicable in the aeration cooling of industrial and mining enterprises, civil buildings.
Description
Technical field
The utility model belongs to metallurgical machinery equipment field, mine, is specifically related to the centrifugal ventilation in a kind of mineMachine.
Background technology
Ventilation blower is the mechanical energy that relies on input, improves supply gas the side by side machinery of body of gas pressure, and it is a kind ofDriven fluid machinery, modern ventilation blower is widely used in factory, mine, tunnel, cooling tower, vehicle, shipThe ventilation of oceangoing ship and building, dust discharge and cooling, the ventilation of boiler and industrial furnace and air inducing, air conditioning is establishedCooling in standby and domestic electric appliance and ventilating, the oven dry of cereal and selecting and recommending, wind-tunnel wind regime and aircushion vehicleInflation and propelling etc., centrifugal fan is mainly made up of impeller and casing, and the impeller of small-sized ventilation blower directly fillsOn motor, in, large-scale ventilation blower connects with motor by shaft coupling or belt pulley, centrifugal fanBe generally one-sided air inlet, use single-stage impeller, what flow was large can bilateral air inlet, with two back-to-back impellers,But the centrifugal fan that nowadays mostly mine is used also exist power high, turn round unstable, noise is largeEtc. drawback.
Utility model content
The purpose of this utility model is just to provide in order to address the above problem a kind of mine centrifugal ventilationMachine.
The utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of mine centrifugal fan, comprises impeller, air inlet, boss rod and casing, casing one sideBe provided with air inlet, casing opposite side is provided with impeller, is used for making the gas pressure and the speed that enter to be carriedHeight, impeller lower end is provided with belt pulley, and belt pulley one side is provided with boss rod, and boss rod one side is provided with axleHold, bearing lower end is provided with bearing bracket stand, and casing lower end is provided with air outlet.
In said structure, centrifugal fan with engine (being mainly motor) drives impeller at volute casingInterior rotation, air sucks from impeller center through air inlet, impeller by the arc thin plate type blade of ten hypsokinesis,Shaped form shroud and dull and stereotyped hub disk composition, through dynamic and static balance correction, due to the dynamic action of blade to gas,Gas pressure and speed are improved, and get rid of to casing along Ye Dao under centrifugal action, arrange from air outletGo out, because gas flowing in impeller is mainly in sagittal plane.
As preferred version of the present utility model: air inlet is fixed on casing, and impeller is arranged on casing.
As preferred version of the present utility model: belt pulley is connected with boss rod, and boss rod is connected with bearingConnect.
As preferred version of the present utility model: bearing is fixed on bearing bracket stand, and bearing bracket stand is boltedOn casing.
Beneficial effect is: casing adopts integral form, and intensity is large, and impeller is through dynamic and static balance correction, skyGas is functional, and air inlet is made entirety, with the cross section of axially parallel be curve shape, can make gas smoothEnter impeller, and loss is less, efficiency is high, and power consumption is little, smooth running, and noise is low, structure improvement, justIn safeguarding and dismounting, air quantity is large, and blast is stable, aeration-cooling applicable to industrial and mining enterprises, civil buildings.
Brief description of the drawings
Fig. 1 is the structural representation of a kind of mine described in the utility model centrifugal fan;
Fig. 2 is the side view of a kind of mine described in the utility model centrifugal fan.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As Figure 1-Figure 2, a kind of mine centrifugal fan, comprises impeller 1, air inlet 2, main frameAxle 4 and casing 7, casing 7 one sides are provided with air inlet 2, facilitate the suction of air, and casing 7 opposite sides are establishedBe equipped with impeller 1, be used for making the gas pressure and the speed that enter to be improved, impeller 1 lower end is provided with belt pulley3, be used for transmitting power, belt pulley 3 one sides are provided with boss rod 4, and boss rod 4 one sides are provided with bearing 5,Bearing 5 lower ends are provided with bearing bracket stand 8, and casing 7 lower ends are provided with air outlet 6.
In said structure, centrifugal fan with engine (being mainly motor) drives impeller 1 at volute machineThe interior rotation of shell 7, air sucks from impeller 1 center through air inlet 2, and impeller 1 is by the circular arc of ten hypsokinesisSheet-type blade, shaped form shroud and dull and stereotyped hub disk composition, through dynamic and static balance correction, because blade is to gasThe dynamic action of body, gas pressure and speed are improved, and get rid of to machine along Ye Dao under centrifugal actionShell 7, discharges from air outlet 6, because gas flowing in impeller 1 is mainly in sagittal plane.
As preferred version of the present utility model: air inlet 2 is fixed on casing 7, and impeller 1 is arranged on machineOn shell 7, belt pulley 3 is connected with boss rod 4, and boss rod 4 is connected with bearing 5, and bearing 5 is fixingOn bearing bracket stand 8, bearing bracket stand 8 is bolted on casing 7.
More than show and described general principle of the present utility model, principal character and advantage. The skill of the industryArt personnel should understand, and the utility model is not restricted to the described embodiments, in above-described embodiment and descriptionThat describes just illustrates principle of the present utility model, do not departing under the prerequisite of the utility model spirit and scope,The utility model also has various changes and modifications, and these changes and improvements all fall into this claimed practicalityIn novel scope. The claimed scope of the utility model is defined by appending claims and effect thing thereof.
