Abstract
The utility model relates to blower fan field, is specifically related to a kind of explosion-proof fan, has good explosion-proof electrostatic-proof function.For achieving the above object, the utility model by the following technical solutions, explosion-proof fan, comprise blower fan, blower fan periphery arranges guard shield, offers intake grill and exhaust outlet on the housing of guard shield, the exhaust port place of blower fan arranges ventilator, and the outer end of ventilator is arranged at exhaust outlet place.By above technological scheme, the periphery of blower fan arranges guard shield, can not affect under the prerequisite of blower fan work, effectively isolated blower fan and external environment condition, thus make blower fan there is good explosion-proof electrostatic-proof function.
Description
Technical field
The utility model relates to blower fan field, is specifically related to a kind of explosion-proof fan.
Background technique
At present, centrifugal blower is widely used in ventilation, the dust discharge and cooling of factory, mine, tunnel, cooling tower, vehicle, boats and ships and building; The ventilation of boiler and industrial furnace and air inducing; Cooling and ventilation in the apparatus of air conditioning and domestic electric appliance; The oven dry of cereal and selecting and recommending; Inflation and the propelling etc. of wind-tunnel wind regime and Hovercraft.But, in inflammable and explosive industries such as some chemical fibre chemical industry, need to carry out explosion-proof antistatic processing to blower fan.
Model utility content
The purpose of this utility model provides a kind of explosion-proof fan, has good explosion-proof electrostatic-proof function.
For achieving the above object, the utility model by the following technical solutions, explosion-proof fan, comprise blower fan, blower fan periphery arranges guard shield, offers intake grill and exhaust outlet on the housing of guard shield, the exhaust port place of blower fan arranges ventilator, and the outer end of ventilator is arranged at exhaust outlet place.
Further, between the bottom of the support of described blower fan and guard shield inwall bottom surface, rubber base plate is set.
Further, between the support of described blower fan and rubber base plate, vibration damper is set.
Further, the outside of the impeller of described blower fan adopts carbon steel layer.
Further, on the housing of described guard shield, explosion-proof layer is set.
Further, described guard shield is zine plate layer, and explosion-proof layer is polytetrafluoroethylene floor.
By above technological scheme, the periphery of blower fan arranges guard shield, can not affect under the prerequisite of blower fan work, effectively isolated blower fan and external environment condition, thus make blower fan there is good explosion-proof electrostatic-proof function.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the enlarged view that Fig. 1 centre circle shows part.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
A kind of explosion-proof fan, comprises blower fan 10, and blower fan 10 peripheries arrange guard shield 20, and in other words, blower fan 10 is to arrange in the inner chamber 23 of protective casing 20.Can normally work in order to ensure blower fan 10, offer intake grill 21 and exhaust outlet 22 on the housing of guard shield 20, the exhaust port place of blower fan 10 arranges ventilator 11 simultaneously, and the outer end of ventilator 11 is arranged at exhaust outlet 22 places.In general, ventilator 11 adopts flexible pipe to connect, and blower fan 10 just can pass through intake grill 21 air amounts like this, and then passes through ventilator 11, exhaust outlet 22 by Bas Discharged.
Further, in the time working and between protective casing 20, produce vibration friction for fear of blower fan 10, between the bottom of the support 12 of described blower fan 10 and guard shield 20 inwall bottom surfaces, rubber base plate 30 is set.Further, between the support 12 of described blower fan 10 and rubber base plate 30, vibration damper 40 is set, vibration damper 40 can reduce the vibration friction between blower fan 10 and protective casing 20 more effectively.
Further, the skin of the impeller 13 of described blower fan 10 adopts carbon steel layer, thereby further improves the explosion-proof antistatic performance of blower fan 10.
Further, can effectively stop inner static conduct to outside in order to ensure protective casing 20, described guard shield 20 is zine plate layer, and explosion-proof layer 24 is set on its external casing simultaneously, and as preferably, explosion-proof layer 24 is polytetrafluoroethylene floor.
