Description
Technical field
The utility model relates to a kind of blower fan, is specifically related to a kind of explosion-proof fan of preventing dust steam.
Background technique
Blower fan is a kind of for compressing and carry the machinery of gas, and from energy viewpoint, it is the one machinery mechanical energy of prime mover being changed into gas energy.Centrifugal blower is formed primarily of critical pieces such as intake grill, impeller, spiral cases, be generally used for the room ventilation ventilation of the buildings such as factory, also can be used for the high pressure forced ventilation of boiler, forge etc., and be applied to mass transport etc. occasion, the centrifugal force mainly utilizing vane rotary to produce makes medium obtain energy, is then static pressure through spiral case and volute outlet diffuser by part kinetic transformation.The kind of conventional centrifugal blower conveying gas be air or other nonflammable not easily sudden and violent, to the non-corrosive gas of steel.
Explosion-proof fan is mainly applicable to Indoor environment ventilation and the cooling of the explosion risk environment such as factory, hospital, oil, storage, military project.There is the problem that dust is more, moist in these hazardous environments, conventional blower fan is not enough due to poor sealing, protection, easily occurs that motor internal easily enters dust or steam, and then causes motor damage and safety problem.
Summary of the invention
The utility model object be in order to overcome the deficiencies in the prior art provide a kind of can the explosion-proof fan of preventing dust steam.
For achieving the above object, the technical solution adopted in the utility model is: a kind of explosion-proof fan of preventing dust steam, it comprises Blower Housing, is fixed on the multiple supporting foots bottom Blower Housing, the arbor being arranged on Blower Housing central authorities, the motor be fixed on arbor, to fix with motor and the impeller rotated under it drives, the seal arrangement being individually fixed in motor two ends, and motor be electrically connected and be seal-installed on the anti-explosion terminal box of Blower Housing side.
Optimally, it also comprises the many struts being supported on seal arrangement and impeller.
Optimally, described anti-explosion terminal box is also fixedly connected by screw thread and arbor.
Optimally, described motor is external rotor electric machine.
Optimally, described seal arrangement is made up of outside framework oil seal and the sealing cover body be located on outside framework oil seal.
Because technique scheme is used, the utility model compared with prior art has following advantages: the explosion-proof fan of the utility model preventing dust steam, seal arrangement is fixedly installed on the one hand at motor two ends, effectively can prevent dust and steam from entering motor, thus avoid the performance affecting motor; On the other hand will be seal-installed on Blower Housing side with the motor anti-explosion terminal box that is electrically connected, guarantee that motor lead-out wire part does not produce the hazards such as electric arc.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of the explosion-proof fan of the utility model preventing dust steam;
Wherein, 1, Blower Housing; 2, supporting foot; 3, arbor; 4, motor; 5, impeller; 6, anti-explosion terminal box; 7, seal arrangement; 8, strut.
Embodiment
Below in conjunction with embodiment shown in the drawings, the utility model is further described.
The explosion-proof fan of preventing dust steam as shown in Figure 1, mainly comprises Blower Housing 1, motor 4, impeller 5, anti-explosion terminal box 6 and seal arrangement 7.
Wherein, the bottom of Blower Housing 1 is fixed with multiple supporting foot 2; Arbor 3 is arranged in the cavity of Blower Housing 1 central authorities, for fixed electrical machinery 4; Impeller 5 and motor 4 fix, and it rotates under the driving of motor 4, thus produce air quantity; Anti-explosion terminal box 6 and motor 4 are electrically connected and are seal-installed on the side of Blower Housing 1, play certain explosion-proof, and motor 4 lighting outlet are caused in anti-explosion terminal box 6 by motor axis hole, guarantee that lighting outlet part does not produce the hazards such as electric arc; Seal arrangement 7 has two, and sealing is fixed on the two ends of motor 4 respectively, effectively can prevent dust and steam from entering motor, thus avoid the performance affecting motor.
In the present embodiment, as shown in Figure 1, this explosion-proof fan also comprises many struts 8, and they are supported between seal arrangement 7 and impeller 5.Anti-explosion terminal box 6 is also fixedly connected by screw thread and arbor 3, thus the explosion-proof performance motor 4 improving blower fan is external rotor electric machine, when motor 4 drives external rotor (i.e. outer steel) assembly to rotate, internal rotor (namely magnet steel) assembly and impeller synchronous rotary is driven through separation sleeve by the effect magnetic line of force in magnetic field, medium is completely enclosed within static separation sleeve, thus reach the object that No leakage pumps medium, the sealability of blower fan can be improved.Seal arrangement 7 is made up of outside framework oil seal and the sealing cover body be located on outside framework oil seal, and it increases explosion suppresion surface with motor 4 joint, reaches that raising is dust-proof, the effect of anti-steam and flame proof grade.
Above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection domain of the present utility model.
