Abstract
The invention discloses an outdoor smoke exhaust fan. The outdoor smoke exhaust fan comprises an outer barrel with two ends open, an inner barrel is arranged in the outer barrel, the length of the inner barrel is 2/3 to 3/4 that of the outer barrel, the diameter of the inner barrel is 1/4 to 3/4 that of the outer barrel, a supporting rod is arranged between an outer wall on the lower portion of the inner barrel and an inner wall of the outer barrel, the inner barrel is fixed in the outer barrel through the supporting rod, the upper end of the inner barrel is provided with an air inlet pipe of a communicating pipe of an inner cavity of the inner barrel, a motor is arranged in the inner cavity of the inner barrel, the upper end and the lower end of the motor are fixed in the inner barrel through supporting plates, one end of the inner barrel is provided with an opening, and a rotating part of the motor extends out of the opening to be connected with a fan blade. The motor is arranged in the inner barrel, air flow of the motor in work is led in through an air inlet pipe, negative pressure in the inner barrel is avoided, the problem that waste gas flows across the motor is solved, the motor is effectively protected, and the service life of the motor is prolonged.
Description
Technical field
The present invention relates to a kind of outdoor use smoke exhaust fan.
Background technique
Its motor of blower fan using is at present to be all directly exposed to outside, in occasions such as high temperature, high corrosion, very easily suffers erosion, and fan motor is short working life, need to often change, and increases user cost and maintenance workload, also affects normal production work; At occasion blower fans such as high temperature, high corrosion, can not stop and want continuous operation in addition, and the blower fan power consumption using is at present all larger.
Summary of the invention
The invention provides a kind of outdoor use smoke exhaust fan, effectively protect the motor in inner core not receive exhaust emission pollution.
The technical solution adopted in the present invention is to achieve the above object of the invention: a kind of outdoor use smoke exhaust fan, comprise the urceolus with both ends open, in described urceolus, be provided with inner core, the shaft axis of urceolus and the shaft axis of inner core coincide, the length of inner core accounts for 2/3～3/4 of urceolus length, the diameter of described inner core accounts for 1/4～3/4 of urceolus diameter, between the below outer wall of described inner core and outer tube inner wall, be provided with pole, inner core is in pole is fixed on urceolus, the upper end of inner core is provided with the air intake pipe with interior tube inner chamber connecting tube, described air intake pipe one end is fixedly connected with inner core, the other end of air intake pipe stretches out urceolus, in the inner chamber of described inner core, be provided with motor, described top and bottom are fixed in inner core through fagging, one end of described inner core has opening, the rotation of motor is stretched out and is connected with flabellum from this opening.
Further, described inner core, pole, air intake pipe and urceolus form through formed by integrally casting.
Further, described fagging is arranged in the inner side of inner core intake grill.
The invention has the beneficial effects as follows: smoke exhaust fan is in the past in the process of smoke evacuation; the waste gas of discharging often can contact with motor, can be that motor is impaired for a long time after contact, especially the coil of motor internal; contacting for a long time perishablely afterwards with sour gas, affecting life-span of motor.
, through inner core, motor is arranged in inner core now, the air-flow of motor when work passes into through suction tude, avoids occurring negative pressure in inner core, avoids waste gas streams through motor, effectively protects motor, extends its working life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Wherein, 1, urceolus, 2, inner core, 3, motor.
Embodiment
As shown in Figure 1, a kind of outdoor use smoke exhaust fan, comprise the urceolus 1 with both ends open, in described urceolus 1, be provided with inner core 2, the shaft axis of the shaft axis of urceolus 1 and inner core 2 coincides, the length of inner core 2 accounts for 2/3～3/4 of urceolus 1 length, the diameter of described inner core 2 accounts for 1/4～3/4 of urceolus 1 diameter, between the below outer wall of described inner core 2 and urceolus 1 inwall, be provided with pole, inner core 2 is in pole is fixed on urceolus 1, the upper end of inner core 2 is provided with and the inner core air intake pipe of 2 inner chamber connecting tube, described air intake pipe one end is fixedly connected with inner core 2, the other end of air intake pipe stretches out urceolus 1, in the inner chamber of described inner core 2, be provided with motor 3, described top and bottom are fixed in inner core 2 through fagging, one end of described inner core 2 has opening, the rotation of motor 3 is stretched out and is connected with flabellum from this opening.
Inner core 2, pole, air intake pipe and urceolus 1 form through formed by integrally casting.Fagging is arranged in the inner side of inner core 2 intake grills.
: smoke exhaust fan is in the past in the process of smoke evacuation; the waste gas of discharging often can contact with motor 3, can be that motor 3 is impaired for a long time after contact, especially the coil of motor 3 inside; contacting for a long time perishablely afterwards with sour gas, affecting life-span of motor 3.
, through inner core, motor is arranged in inner core now, the air-flow of motor when work passes into through suction tude, avoids occurring negative pressure in inner core, avoids waste gas streams through motor, effectively protects motor, extends its working life.
The motor shroud of the corrosive gas isolation of the occasions such as high corrosion, in motor shroud, be provided with induced air pipe, induced air pipe is from other clean local air of introducing, the clean air of introducing blows to fan blade from the ring-type ventilation flue between motor and motor shroud (its width >=1 millimeter), and motor component is subject to less than erosion; [0012] fan blade cross section is designed to increase by one section of little arc flanging on former large arc basis simultaneously, under the prerequisite that guarantees same intensity, can reduce vane thickness, alleviated leaf weight, blower fan load decreases, thereby can save the power consumption of 30-80%.
More than describe preferred embodiment of the present invention in detail.Should be appreciated that those of ordinary skill in the art just can design according to the present invention make many modifications and variations without creative work.Therefore, all technician in the art on the basis of existing technology by the available technological scheme of logical analysis, reasoning, or a limited experiment, all should fall within the scope of protection of the present invention under this invention's idea.
