Abstract
The utility model relates to a powerful fan, solved ordinary fan air exhaust / supply air the nearly energy of distance subduct soon, supply air apart from closely, air exhaust extremely great not enough. It includes flabellum, motor, motor support, a fan section of thick bamboo, characterized by: be equipped with spirally guided piece (5), the center and the coincidence of fan section of thick bamboo axle center of spirally guided piece (5), spirally guided piece (5) along a fan section of thick bamboo (4) axial installation in the inboard of a fan section of thick bamboo (4). The utility model has the advantages of: simple structure forms rotatory wind direction for the distance of airing exhaust / supply air is far away.
Description
Technical field
The utility model belongs to electro-mechanical arts, is specifically related to a kind of strong fan.
Background technique
In petroleum production, accumulating, the many links of processing, the operational site such as involved factory building, pumping plant, terminal, note poly-station, metering room, all need to ventilate to it, to guarantee the health of human body of operational site personnel and to avoid the generation of blast accident, this is China's relevant law, regulation hard and fast rule, and it is necessary that this is also that petrochemical industry produces the particularity had.Poisonous, the harmful gas of many kinds or liquid can be produced in petrochemical production process, and the density of a lot of toxic gas is greater than the density of air, common blower fan row/air-supply all can leave dead angle, as the corner of larger factory building, equipment compact district, be positioned at the foundation ditch etc. of low level, leave hidden danger to safety in production, existing solution strengthens power of fan, increase blower fan density.Not enough apparent, as energy consumption, cost increase, if working environment can cool off again in the winter time/and cold, affect comfort level.
Model utility content
The purpose of this utility model: be the deficiency solving above-mentioned technology, provide a kind of strong fan, forms the wind direction rotated, makes air draft/air supplying distance far away.
The technological scheme realizing the utility model object is: a kind of strong fan, comprise flabellum, motor, electric machine support, blower fan cylinder, it is characterized in that: be provided with spirally-guided sheet 5 in the inner side of blower fan cylinder 4, the center of spirally-guided sheet 5 and blower fan cylinder axis coinciding, spirally-guided sheet 5 is axially installed along blower fan cylinder 4.
It is characterized in that: spirally-guided sheet 5 is four.
The utility model has following beneficial effect: structure is simple, forms the wind direction rotated, and makes air draft/air supplying distance comparatively far away, does not have dead angle.
Accompanying drawing explanation
Fig. 1 is the B-B face partial sectional view of plan view of the present utility model.
Fig. 2 is the sectional view in Figure 1A-A face.
Component in accompanying drawing and corresponding sequence number illustrate: 1. flabellum, 2. motor, 3. electric machine support, 4. blower fan cylinder, 5a. spirally-guided sheet, 5b. spirally-guided sheet.Wherein 5a, 5b are identical spirally-guided sheets, can be referred to as: 5 spirally-guided sheets, and just position is different with angle, in order to be convenient to illustrate, avoid ambiguity in sectional view shown in Fig. 1.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.This strong fan, comprise flabellum, motor, electric machine support, blower fan cylinder, these are identical with prior art.Unlike: be provided with spirally-guided sheet 5 in the inner side of blower fan cylinder 4, the center of spirally-guided sheet 5 and blower fan cylinder axis coinciding, spirally-guided sheet 5 is axially installed along blower fan cylinder 4.Spirally-guided sheet 5 is all available from two to six.Article two, the angle of spiral can be larger, the projection angle of wall scroll 180 °, and windage is larger; Article three, and four ideal, i.e. the projection angle 120 ° of wall scroll and 90 °, the present embodiment is four, and windage is less.
Working principle of the present utility model, in fact the same with natural tornado formation basic theory, the artificial air-flow manufacturing rotation, and then form negative pressure center, gas remotely or lighter object can be taken away that (very large/heavy object can be rolled by tornado, and this is general knowledge.), do not stay dead angle and deposition gases, reach the Workplace Safety hidden danger such as thorough displaced air, elimination factory building, pumping plant, terminal, note poly-station, metering room, to guarantee the health of human body of operational site personnel and to avoid the generation of blast accident.
Claims (2)
1. strong fan, comprise flabellum, motor, electric machine support, blower fan cylinder, it is characterized in that: be provided with spirally-guided sheet (5) in the inner side of blower fan cylinder (4), the center of spirally-guided sheet (5) and blower fan cylinder axis coinciding, spirally-guided sheet (5) is axially installed along blower fan cylinder (4).
2. strong fan according to claim 1, is characterized in that: spirally-guided sheet (5) is four.
