Description
Technical field
The utility model relates to a kind of blower fan, specifically a kind of safety and shock-absorption explosion-proof fan.
Background technique
Explosion-proof fan is applied in the higher place needing again to ventilate of combustable gas concentration, such as underground coal mine, boiler room etc.As far as possible the technological requirement of explosion-proof fan avoids rotary component (draught fan impeller), can not produce spark, thus the inflammable gas that ignites causes explosion phenomenon when occurring to rub with housing under special circumstances.Because explosion-proof fan is all be applied to hazardous location, have various collision unavoidably, therefore existing explosion-proof fan can strengthen shockproof properties, and the explosion-proof fan of existing explosion-proof fan also needs to be strengthened further, explosion-proof fan can produce noise along with the rotation of rotary component when work, effectively can improve working environment.Can explosion-proof fan also plays a very important role in iron and steel is produced, because ensure that it is long-term, stable operation is related to the manufacturing efficiency of iron and steel enterprise.But in actual production, explosion-proof fan operation troubles happens occasionally, have a strong impact on safety in production and the environment protection standard work of Iron And Steel Plant.Wherein, because explosion-proof fan housing design is unreasonable, fault that is that cause also occupies certain ratio.At present, explosion-proof fan housing design is unreasonable to be shown: rear guide vane is single circular arc type curve, affects fan operation efficiency; Because rear guide vane is single circular arc type curve, so rigidity is not enough, causing blower fan to vibrate when high speed, when needing carrying out blower fan Reconstruction in field especially to improve rotation speed of fan, then running into the problem of casing recurring structure resonance; Bearing block base structural rigidity is not enough, also causes vibration; There is no suitable access opening, cause Site Detection and safeguard inconvenience; Casing internal does not set up thermal insulation layer or thermal insulation layer weak effect, causes Bearing Temperature and reduces bearing life etc.
Model utility content
It is simple that the purpose of this utility model is to provide a kind of structure, and safety and shock-absorption explosion-proof fan easy for installation, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technological scheme:
A kind of safety and shock-absorption explosion-proof fan, comprise pedestal, motor, speed changer and housing, described pedestal upper right is provided with motor, and be provided with transmission support bracket above motor, be installed with speed changer above transmission support bracket, motor connects speed changer by belt drives; Be provided with housing on the left of speed changer, housing is installed on pedestal, is provided with impeller in housing, and the live axle of speed changer drives through housing and connects impeller, and live axle and impeller joint are provided with sealed cover, and live axle and housing joint are provided with stuffing box gland; The inwall of housing is provided with shakeproof layer, and described shakeproof layer adopts insulation rubber pad, and described shakeproof layer is provided with thermal-protective coating, and described thermal-protective coating adopts fiber glass material; Be provided with intake grill on the left of described housing, bottom is provided with exhaust outlet, and intake grill front is provided with protective housing, is provided with filter screen between protective housing and impeller; The front end of described intake grill is provided with baffler.
Further, described speed changer is provided with speed changer hanger.
Further, housing hanger is provided with above described housing.
Further, access opening is provided with on the right side of described housing.
Compared with prior art, shakeproof layer of the present utility model adopts insulation rubber pad, has certain shockproof effect when blower fan collides; Described thermal-protective coating adopts fiber glass material, and avoid impeller and directly contact with inner walls, avoid impeller and interior wall friction to produce spark, explosion-proof effect is good; Access opening is provided with on the right side of described housing.Convenient maintenance and deashing work; Intake grill front is provided with protective housing, for the protection of impeller from destruction, is provided with filter screen between protective housing and impeller, and filter screen is convenient to be fallen oarse-grained dust filtration, avoids big dust particle and enters into housing and rub with impeller and produce spark; The front end of described intake grill is provided with baffler, and the noise produced when effectively eliminating blower fan work, improves working environment; The utility model structure is simple, and easy for installation, greatly improve rotation speed of fan, rational structure makes aerodynamic efficiency improve, and blower fan running is more steadily safer.
