Host.
Background technology
Mine ventilation system is an important component of pit mining, is the basic guarantee of mine safety production, mine
It is in Mine Production, continually by fresh air conveying to working face in the pit, supply with the effect of booster
Personnel breathe and dilute and exclude the various toxic, pernicious gases in underground and mine dust, create good working environment, ensure that underground is made
The health and safety of industry personnel.
The booster that domestic production at present uses mainly has the series such as FBD, FB, FBCD, FBY, the electricity of these wind turbines
Machine is all made of two level explosion separation motor, and motor speed is high, and aerodynamic noise is big；The radiated noise of host housing is both greater than 95dB.
Invention content
The purpose of this utility model is exactly for overcome the deficiencies in the prior art, and to provide a kind of low noise of multilayer isolation
Local ventilation machine host.
The technical solution adopted in the utility model is to achieve the goals above：
A kind of low noise local ventilation machine host of multilayer isolation, including motor, impeller, outer cage, inner casing, rubber
Plate, it is characterised in that：Outer cage is connected with inner casing by rubber slab face paste face；There is one layer of core engine inside the inner casing
Shell, forms sealed air noise isolating space between inner casing and core casing, fitting between the forward flange and rear flange of motor pass through
It is fixed on core casing, there is impeller on motor；The outer cage is made of flange, outer layer cylinder, polymeric coating layer, internal layer cylinder,
Outer cage is divided into two halves up and down, and upper and lower two halves screw connection, for flange welding on outer layer cylinder, internal layer cylinder passes through polymeric coating layer
It is fitted on outer layer cylinder, on outer layer cylinder, bolt passes through nut to form jackscrew limitation inner casing and circumferentially or axially moves nut-welding
It is dynamic.
According to a kind of above-described low noise local ventilation machine host of multilayer isolation, it is characterised in that：Described is interior
Sealed air noise isolating space between casing and core casing is filled with glass silk floss.
Compared with prior art the utility model has the beneficial effects that：Setting is isolated by the multilayer to host shell, keeps away
The transaudient effect for having exempted from flange has carried out multiple reflections consumption to the radiated noise of host, and the noise for transmiting host housing is low
In 80dB；The isolation setting of this multilayer can be used for construction tunnel wind turbine.
