Abstract
The utility model discloses a firefighting high-temperature smoke exhaust axial flow fan, which includes a footing, an impeller, a housing, a motor, a belt and a bearing box, wherein the motor is fixedly mounted at the top of the housing and connected with a motor wheel and a fan wheel through belts; the main shaft of the fan wheel and the main shaft at one end of the bearing box are the same, the main shaft at the other end of the bearing box is connected with and drives the main shaft of the impeller; the motor is mounted on a motor frame and welded or bolt fixed to the top part of the housing together with the motor frame; the bearing box is mounted on a support and fixedly mounted at the lower part of the housing together with the support; and the footing with the vibration damping effect is fixedly mounted at the lower part of the housing. The firefighting high-temperature smoke exhaust axial flow fan has the advantages of compact structure, small occupied area, excellent smoke exhaust and ventilation effect, low noise and long service life, and is applicable to the firefighting high-temperature smoke exhaust and ventilation.
Description
Technical field:
The utility model relates to a kind of fire-fighting high temperature smoke evacuation propeller fan, belongs to the technological improvement of blower fan.
Background technique:
Along with the development of modern architecture, people are also increasingly high to the requirement that interior of building ventilates, and all will use ventilation equipment in many megastore, office building, Movie theater etc., and big flow axis flow fan can be applicable to the use of this occasion.Existing big flow axis flow fan mainly is coaxial; When commercial production and fire-fighting smoke evacuation, there are some problems, place in the casing coaxially such as motor, reduced the flow path in air channel with impeller; Operating conditions such as the insulating properties of motor and explosion-proof are received the higher quality requirement; When the gas of discharging is corrosive, when combustibility or high temperature, can cause the corrosion and the blast of motor, personnel casualty accidents appears.In addition, when motor and impeller disalignment, existing blower fan exists volume big, and structure is not compact, and smoke evacuation, ventilation weak effect are not suitable for fire-fighting high temperature smoke-discharging and ventilating and use.
The model utility content:
The purpose of the utility model is exactly the deficiency to existing technology; And a kind of fire-fighting high temperature smoke evacuation propeller fan is provided; This fan motor is external; Avoided motor directly to receive the infringement of high-temperature gas or corrosive gas, had that compact structure, floor space are little, smoke evacuation, ventilation is effective, noise is low, the advantage of long service life.
In order to achieve the above object, the technological scheme of the utility model is following:
A kind of fire-fighting high temperature smoke evacuation propeller fan; Comprise footing, impeller, casing, motor, belt, bearing housing; It is characterized in that: motor is fixedly mounted on the casing top; Connect drive motor wheel and impeller of blower through belt, the main shaft of the main shaft of impeller of blower and bearing housing one end is same main shaft, and the main shaft of the bearing housing the other end connects the drives impeller main shaft.
Further, motor is installed on the motor frame, together with the motor frame through welding or be bolted to the casing top; Bearing housing is rack-mount; Be fixedly mounted on the bottom in the casing together with support, footing is fixed on the outer bottom of casing, and footing has effectiveness in vibration suppression.
Beneficial effect: the utility model motor places the outside of fan casing; Avoided motor directly to receive the infringement of high-temperature gas or corrosive gas,, improved the working efficiency of blower fan through the transmission setting of bearing housing; Through the design of vibration damping footing, the vibrating noise when effectively reducing blower fan work.The utility model compact structure, floor space is little, high working efficiency, little, the long service life of noise, is fit to fire-fighting high temperature smoke evacuation ventilation and ventilates and use.
Description of drawings:
Fig. 1 is the plan view of the utility model;
Fig. 2 is the side view of the utility model.
Among the figure: 1, footing, 2, impeller, 3, casing, 4, motor, 5, the motor wheel, 6, the motor frame, 7, belt, 8, impeller of blower, 9, bearing housing, 10, support.
Embodiment:
Embodiment: see illustrated in figures 1 and 2; A kind of fire-fighting high temperature smoke evacuation propeller fan; Comprise footing 1, impeller 2, casing 3, motor 4, belt 7, bearing housing 9, motor 4 is fixedly mounted on casing 1 top, connects drive motor wheel 5 and impeller of blower through belt 7; The main shaft of the main shaft of impeller of blower 8 and bearing housing 9 one ends is same main shaft, and the main shaft of bearing housing 9 the other ends connects drives impeller 2 main shafts.
Further; Motor 4 is installed on the motor frame 5; Through welding or being bolted to casing 1 top, bearing housing 9 is installed on the support 10, is fixedly mounted on the bottom in the casing 1 together with support 10 together with motor frame 5; Footing 1 is fixed on the bottom outside the casing 1, and footing 1 has effectiveness in vibration suppression.
