Abstract
A rectifying cylinder structure of a jet fan comprises a rectifying cylinder, wherein, a silencing board is arranged at the inner side of a rectifying cylinder housing of the rectifying cylinder, a flow guiding cover is arranged at the middle part of the rectifying cylinder, the silencing board is attached and fixed with the inner side of the rectifying cylinder housing, the flow guiding cover is fixedly connected with the rectifying cylinder housing by a support, and a ventilator is mounted between two rectifying cylinders. According to the structure designs of the rectifying cylinder, the streamline flow guiding cover and the silencing board provided by the utility model, the air mechanics characteristic and the low noise performance of a flow passage can be ensured, the rectifying cylinder of the jet fan provided by the utility model has characteristics of simple structure, convenient mounting and manufacturing, high jet fan efficiency, uniform airflow, low noise and good application effect.
Description
Technical field
The utility model relates to a kind of rectification barrel structure of jet blower, belongs to the industrial fan product technical field.
Background technique
A large amount of at present jet blowers in industrial use, mainly be by ventilator, the rectification tube constitutes, the jet blower of this structure type, the structure of its rectification tube is mainly: the round barrel shape structure, the rectification tube of round barrel shape structure is connected with ventilator, the rectification tube of this round barrel shape structure is not owing to there is the air guide sleeve structure, so jet blower efficient is lower in actual use, mainly be that in use air-flow is easy to generate turbulent phenomenon, influence the aerodynamic performance of jet blower, owing to there is not the acoustical panel structure, jet blower in use noise is also bigger simultaneously.
Summary of the invention
The utility model provides a kind of rectification barrel structure of a kind of jet blower of novelty, adopts acoustical panel and air guide sleeve structure technology, to realize that jet blower has the purpose of good aerodynamic performance and low noise.
The technical solution adopted in the utility model is:
A kind of rectification barrel structure of jet blower, comprise: the rectification tube, rectification cylinder shell inboard at described rectification tube is provided with an acoustical panel, be provided with an air guide sleeve at the middle part of rectification tube, the inboard installation of fitting of acoustical panel and rectification cylinder shell is connected and fixed, air guide sleeve is connected and fixed by support and rectification cylinder shell, and ventilator is installed between two rectification tubes.
Acoustical panel is tabular drum-shaped structure, is covered with the bloop of regular arrangement on the drum shape plate.
Air guide sleeve is a streamlined structure, and integral body is tack cone-shaped streamlined structure, is installed on the neutral position of rectification cylinder shell.
The utility model beneficial effect is:
Owing to adopted the rectification barrel structure of a kind of jet blower of the present utility model, fairshaped air guide sleeve and rectification tube acoustical panel structural design, the air dynamic behaviour and the low-noise performance of runner have been guaranteed, the rectification barrel structure of a kind of jet blower of the present utility model has: simple in structure, make easy for installation, jet blower efficient height, air-flow is even, noise is low, the characteristics that using effect is good.

Fig. 2: the left view that is a kind of jet blower of the utility model;
Fig. 3: the sectional view that is the rectification barrel structure of a kind of jet blower of the utility model.
Among Fig. 1,2: ventilator 1, rectification tube 2;
Among Fig. 3: rectification cylinder shell 21, acoustical panel 22, air guide sleeve 23, air-flow path 24.
Embodiment
As shown in Figure 1 and Figure 2.
Jet blower, mainly by: ventilator 1,2 in rectification tube are formed.
A kind of rectification barrel structure of jet blower, comprise: rectification tube 2, rectification cylinder shell 21 inboards at described rectification tube 2 are provided with an acoustical panel 22, be provided with an air guide sleeve 23 at the middle part of rectification tube 2, acoustical panel 22 is connected and fixed with the 21 inboard installations of fitting of rectification cylinder shell, air guide sleeve 23 is connected and fixed by support and rectification cylinder shell 21, and ventilator 1 is installed between two rectification tubes 2.
Basic functional principle: when blower fan starts use, because the drainage of air guide sleeve, the uniformity and the laminarity of air-flow have been guaranteed, make the jet blower working efficiency greatly improve, simultaneously because the noise elimination effect of acoustical panel, make blower fan noise when work greatly reduce, improved the aerodynamic performance of blower fan.
