Abstract
The utility model discloses a ventilator. The ventilator comprises a cylindrical shell, the shell includes an air inlet end and an air outlet end along the length direction, a motor and a rotating fan are fixed in the shell, the motor comprises a revolving shaft which is connected with the rotating fan, the rotating fan comprises a fan body and a rotating sheet which is fixed to the fan body, a cleaning screen is arranged at the end of the revolving shaft, a mounting sleeve is arranged on the contact of the cleaning screen and the revolving shaft, and the mounting sleeve is fixed to the revolving shaft through a bolt. The fan body is provided with an anti-movement frame which is connected with the cleaning screen, and the anti-movement frame is fixed to the cleaning screen through a screw. The rotating sheet is corrugated in the length direction, and sound-reducing salient points are formed on a windward side at the end of the rotating sheet. By arranging the cleaning screen, a better impurity filtering effect is achieved, the gas conveying quality is improved, and environmental pollution is avoided. The rotating sheet of the shape has large air delivery amount and high efficiency. By forming the sound-reducing salient points, the wind power of wind impacting the edge of the rotating sheet is weakened, and noise generated by over high wind power of wind impacting the wedge of the rotating sheet is avoided.
Description
Technical field
The utility model relates to mechanical engineering field, especially relates to a kind of ventilator.
Background technique
Ventilator is a kind of product type of blower fan, and the performance of ventilator is set forth and mainly contained flow, pressure, power, efficiency and rotating speed.The size of noise is also the important technology index of ventilator in addition.
The ventilator that existing air quantity is larger, noise is also larger conventionally; The ventilator that noise is less, air quantity is also less; And when ventilator is had relatively high expectations in situation for dried foods or other gas degrees of purity, existing ventilator adopts, at wind inlet end, filter screen is set, when blower fan work, filter screen keeps motionless, the effect of its filtration is poor, partial impurities still can enter in ventilator with the wind, the quality that reduces first air-supply, second impurity can affect the normal use of ventilator; And during as exhaust, filter not thoroughly, and in gas, contain more impurity just directly to pass in air, pollute the environment.
Model utility content
The utility model, in order to overcome the deficiencies in the prior art, provides a kind of conveying gas weight that improves, and strengthens the ventilator of carrying air quantity.
To achieve these goals, the utility model is by the following technical solutions: a kind of ventilator, comprise columnar shell, described shell is divided into wind inlet end and outlet air end along its length, is fixed with motor and rotation fan in shell, and motor comprises the rotating shaft that connects rotation fan, rotation fan comprises fan body and is fixed on the rotating plate on fan body, described roller end is provided with a clean net, and this clean net and rotating shaft contacting point are provided with installation sleeve, and this installation sleeve is fixed by latch and rotating shaft; Described fan body has an anti-frame that moves being connected with clean net, and it is fixing with clean net by screw that this prevents moving frame; Described rotating plate is in wave shape along its length, described rotating plate end, and the surface of a side is provided with and subtracts sound salient point windward.
As preferably, the netted round structure that described clean net is made up of stainless steel material, the diameter of clean net is close to the internal diameter of shell.
In sum, the utlity model has following advantage: the effect that clean net is set has than the filter screen that is fixed at present wind inlet end edge better impurity screening, improve the quality of air, during as exhaust or ventilation, avoid environmental pollution, while use as blast device, improve the quality that transmits gas; The clean web frame of this structure is simple, convenient for production, and installation and removal easily; Arrange and anti-move frame, avoid carrying that the wind-force of wind is excessive causes the mobile or deformation of clean net, further guaranteed the stability of clean net, the defeated air quantity of rotating plate of this shape is large, and efficiency is high; This subtracts sound salient point and has weakened the wind-force that impacts rotating plate edge wind, and the wind-force of avoiding impacting rotating plate edge wind is excessive and produce noise.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
In order to make those skilled in the art person better understand the utility model scheme, below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is carried out to clear, complete description.
As shown in Figure 1, a kind of ventilator, comprise columnar shell 1, the inside of shell 1 forms the mobile passage of supplied gas, described shell 1 is divided into wind inlet end 11 and outlet air end 12 along its length, in shell 1, be fixed with motor 2 and rotation fan 3, motor 2 comprises the rotating shaft 21 that connects rotation fan 3, rotation fan 3 comprises fan body 32 and is fixed on the rotating plate 31 on fan body 32, described rotating shaft 21 ends are provided with a clean net 4, this clean net has better impurity screening effect than the filter screen that is fixed at present wind inlet end edge is set, improve the quality of air, during as exhaust or ventilation, avoid environmental pollution, while use as blast device, improve the quality that transmits gas.
Concrete, described clean net 4 is provided with installation sleeve with rotating shaft 21 contacting points, and this installation sleeve is fixing by latch and rotating shaft 21, and the clean web frame of this structure is simple, convenient for production, and installation and removal are easily; Described fan body 32 has an anti-frame 5 that moves being connected with clean net 4, and this is anti-, and to move frame 5 fixing with clean net 4 by screw, this is set and anti-ly moves frame, avoids carrying that the wind-force of wind is excessive causes clean net to move or deformation, has further guaranteed the stability of clean net.
Further, described rotating plate 31 is in wave shape along its length, and the defeated air quantity of rotating plate of this shape is large, and efficiency is high; Described rotating plate 31 ends, the surface of a side is provided with and subtracts sound salient point 311 windward, and this subtracts sound salient point and has weakened the wind-force that impacts rotating plate edge wind, avoids impacting the excessive generation noise of wind-force of rotating plate edge wind.
In order to make the better effects if of the clean anti-impurity of netting, the netted round structure of described clean net 4 for being made by stainless steel material, the diameter of clean net 4 is close to the internal diameter of shell 1.
Obviously, described embodiment is only a part of embodiment of the present utility model, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment who obtains under creative work prerequisite, all should belong to the scope of the utility model protection.
