Abstract
The utility model provides a kind of coal mine ground propeller fan, it comprises cylindrical shell and is housed at least one impeller in this shell, this shell both ends open, one end of this shell is intake grill, its the other end is exhaust outlet, air channel is formed between this intake grill and this exhaust outlet, this impeller comprises rotating shaft and some blades, this rotating shaft is parallel with this air channel, this some blade shroud also arranges in the form of a ring around the distribution of this rotating shaft uniform intervals, wherein, this coal mine ground propeller fan also comprises at least one stiffening ring extended along the direction being parallel to this rotating shaft, this stiffening ring is formed in one structure, each blade offers at least one break slot, this stiffening ring is welded on this some blade by the break slot on each blade.This ventilator integral embedded type stiffening ring strengthens the structural strength of blade, and there is not decentraction jumping phenomena, stiffening ring forms along the direction extension being parallel to this rotating shaft simultaneously, air channel can not be disturbed, thus, coal mine ground propeller fan can overcome the working environment that medium powder dust content is higher, blade very easily weares and teares.
Description
Technical field
The utility model relates to a kind of axial-flow blower equipment.
Background technique
In the working environment that traditional coal mine ground propeller fan very easily weares and teares due to, blade higher at medium powder dust content, after the worn out blade of dust, unequal dust residue is left in each blade cavity, cause the very fast disequilibrium of whole impeller, cause impeller to produce high vibration, even lead to equipment accident.Bending blade insufficient strength in addition, analyze according to mechanical model simply supported beam Force principle, suffered by blade mid point, flexural stress is maximum, must take strengthening measure, and the prerequisite of this strengthening measure is little as much as possible to impeller effect of aerodynamic performance.Therefore the research emphasis that the better and coal mine ground propeller fan that can overcome the working environment that medium powder dust content is higher, blade very easily weares and teares of a structural strength is those skilled in the art how is designed.
Model utility content
For above-mentioned defect and the problem of prior art, the utility model object there is provided one can overcome that medium powder dust content is higher, blade very easily weares and teares coal mine ground propeller fan.
In order to achieve the above object, the utility model provides following technological scheme:
A kind of coal mine ground propeller fan, it comprises cylindrical shell and is housed at least one impeller in this shell, this shell both ends open, one end of this shell is intake grill, its the other end is exhaust outlet, air channel is formed between this intake grill and this exhaust outlet, this impeller comprises rotating shaft and some blades, this rotating shaft is parallel with this air channel, this some blade shroud also arranges in the form of a ring around the distribution of this rotating shaft uniform intervals, wherein, this coal mine ground propeller fan also comprises at least one stiffening ring extended along the direction being parallel to this rotating shaft, this stiffening ring is formed in one structure, each blade offers at least one break slot, this stiffening ring is welded on this some blade by the break slot on each blade.
Further, the break slot on described each blade is opened on the inner side of this rotating shaft, and this stiffening ring is welded on the inner side of respective vanes by the break slot on each blade.
The beneficial effects of the utility model are, integral embedded type stiffening ring strengthens the structural strength of blade, and there is not decentraction jumping phenomena, stiffening ring forms along the direction extension being parallel to this rotating shaft simultaneously, air channel can not be disturbed, thus, coal mine ground propeller fan can overcome the working environment that medium powder dust content is higher, blade very easily weares and teares.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
