Abstract
The utility model provides an explosion-proof axial flow fan and relates to an air exchange device. The explosion-proof axial flow fan is composed of a barrel, a motor and fan blades, wherein a T-shaped rack is fixed in the barrel; the motor is fixed in the T-shaped rack; a power output shaft of the motor is connected with more than three fan blades in an stationary fit manner; the opening of the barrel adjacent to a fan blade end is provided with a protective hood; The motor is arranged in an explosion-proof shell and fixed by virtue of more than three brackets; a power wire of the motor penetrates through the explosion-proof shell and the barrel; the barrel is provided with a ground wire. The explosion-proof axial flow fan provided by the utility model is simple in structure, double-layered and explosion-proof, multiple in protection, good in safety performance, low in manufacturing cost and long in service life, and can be used for reducing the replacement frequency and the overhaul period and saving the production cost, and is scientific, reasonable and energy-saving in overall operation.
Description
Technical field
The utility model relates to a kind of air interchanger, relates in particular to a kind of explosion-proof axial flow fan.
Background technique
Axial-flow blower is a kind of air interchanger that utilizes driven by motor fan work, less demanding to motor under conventional environment, but the axial-flow blower using in inflammable and explosive factory, be the anti-explosion motor that can not produce electrical spark when operation, be mainly used in colliery, petroleum gas, petrochemical industry and chemical industry.In addition in departments such as weaving, metallurgy, town gas, traffic, grain and oil processing, papermaking, medicine, be also widely used.The explosion-proof axial flow fan using in these places at present normally does closed processes at motor, but the continuity of using effect is not very desirable.
Model utility content
The utility model is intended to for the deficiency existing in background technique, and a kind of explosion-proof axial flow fan providing.
Explosion-proof axial flow fan of the present utility model; to be formed by cylindrical shell, motor, electric fan; its inner barrel is fixed wtih T shape frame; described motor is fixed on the crossbeam of T shape frame; on the pto＝power take-off of motor, stationary fit is connecting three above electric fans; the cartridge openings place of described close fan end of blade is provided with mat; described motor is placed in explosion-proof casing and is fixed by three above supports; the power line of motor is through explosion-proof casing and cylindrical shell, and described cylindrical shell is provided with ground wire.
As further improvement of the utility model, the periphery at described cylindrical shell two ends is provided with outer and uniform installation screw on outer.
As further improvement of the utility model, described described explosion-proof casing inwall is provided with heat conduction oil reservoir.
Explosion-proof axial flow fan of the present utility model, reasonable in design, double-layer explosion-proof, explosion-proof effect are good, multiple-protection, Safety performance is good, and manufacture cost is not high, long service life, reduction replacement frequency and repair cycle, saved cost of production, overall operation is scientific and reasonable energy-conservation.
Accompanying drawing explanation
Fig. 1 is the utility model structure rear view.
Fig. 2 is sectional view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing 1 and accompanying drawing 2, to explosion-proof axial flow fan of the present utility model, be described further.
Explosion-proof axial flow fan of the present utility model; to be formed by cylindrical shell 1, motor 2, electric fan 3; its cylindrical shell 1 inside is fixed wtih T shape frame 4; described motor 2 is fixed on the crossbeam of T shape frame 4; on the pto＝power take-off of motor 2, stationary fit is connecting three above electric fans 3; cylindrical shell 1 opening of described close electric fan 3 ends is provided with mat 5; described motor 2 is placed in explosion-proof casing 6 fixing by three above supports 7; the power line of motor 2 is through explosion-proof casing 6 and cylindrical shell 1, and described cylindrical shell 1 is provided with ground wire 8.
Embodiment 2
Explosion-proof axial flow fan of the present utility model; to be formed by cylindrical shell 1, motor 2, electric fan 3; its cylindrical shell 1 inside is fixed wtih T shape frame 4; described motor 2 is fixed on the crossbeam of T shape frame 4; on the pto＝power take-off of motor 2, stationary fit is connecting three above electric fans 3; cylindrical shell 1 opening of described close electric fan 3 ends is provided with mat 5; described motor 2 is placed in explosion-proof casing 6 fixing by three above supports 7; the power line of motor 2 is through explosion-proof casing 6 and cylindrical shell 1, and described cylindrical shell 1 is provided with ground wire 8.The periphery at described cylindrical shell 1 two ends be provided with outer 9 and on outer 9 uniform installation screw 10, described explosion-proof casing 6 inwalls are provided with heat conduction oil reservoir 11.In order to make the radiating effect of explosion-proof casing 6 built-in motors 2 reach best, at the inner heat conduction oil reservoir of housing 1 viscous, paste layer of metal cortex, the heat convection current radiation absorption that metal cortex can send motor 2 conducts to explosion-proof casing 6 by heat conduction oil reservoir 11, airflow passes cylindrical shell 1 inside when motor 2 is worked, the heat that explosion-proof casing 6 is absorbed is taken away, whole process is reasonable, energy-conservation.
