At present, the research utilizing the waste heat overbottom pressure of pressurized gas more than needed to carry out generating electricity is in the ascendant, but mostly because gas pressure fluctuation causes the electricity sent to belong to rubbish electricity, harmonic wave is large, cannot be normally grid-connected, but if utilize the category of the overbottom pressure of pressurized gas for ventilating, good effect can be played.
Model utility content
Main purpose of the present utility model is to overcome deficiency of the prior art, provides a kind of super pneumatic fan that can improve industrial environment and industrial material conveying.For solving the problems of the technologies described above, solution of the present utility model is:
A kind of super pneumatic fan is provided, comprises pneumatic sparger and water conservancy diversion Diffuser; The frame that described pneumatic sparger adopts both ends open, inside is cavity structure, annular chamber is built-in with in frame, and between annular chamber and frame internal cavity structures between be separated with annular chamber sidewall, make between annular chamber and frame internal cavity structures, only to leave annulus and circulate; One end of frame is air suction inlet, and the other end of frame is air ejiction opening, and the outside enclosure interior of air ejiction opening extends to annular chamber sidewall; Frame also has pressurized air air supply opening, and pressurized air air supply opening is communicated with annular chamber and pneumatic sparger is outside;
The air inlet side of described water conservancy diversion Diffuser and the air ejiction opening of pneumatic sparger are connected and fixed.
As further improvement, the air ejiction opening of described pneumatic sparger, by regulating the annulus size between annular chamber and frame internal cavity structures, comes smooth adjustment air-flow velocity and flow.
As further improvement, the air ejiction opening of described pneumatic sparger and the air inlet side of water conservancy diversion Diffuser are threaded connection.
As further improvement, described water conservancy diversion Diffuser adopts the Diffuser of broadening formation or Venturi type.
Working principle of the present utility model: pressurized air enters annular chamber from pressurized air air supply opening, this compressed gas source is in the throttling of annulus place, and the thin air layer of consequent high speed is adsorbed onto annular chamber sidewall, thus produces 90 ° turn to, by annular chamber center; The process that high velocity air flows through annular chamber sidewall causes the generation of area of low pressure, center, thus attracts a large amount of surrounding atmosphere to suck from air suction inlet, through annular chamber center together with high velocity air, sprays from air ejiction opening.
Application of the present utility model: the vacuum suction characteristic utilizing suction side, alternative ventilator completes absorption process and the High Temperature Furnaces heat extraction process of waste gases and smoke dust in various industrial processes, or the transmission to slight small item material such as scrap; Also can utilize the air amplification characteristic of ejection end, the ambient windstream that drainage is tens times blows out together with pressurized air, and the tolerance blown out can be used for the applications such as moisture blows down, industry purges, electronic component cools, weldment cools.
Compared with prior art, the beneficial effects of the utility model are:
1, the utility model only provides power with a small amount of pressurized air, and not needing increases electric energy, even if the used time does not exist electrical equipment interference do not have electric hidden danger yet.
2, the utility model movement-less part, safety coefficient is high, has excellent Safety performance, also can be applicable to some particular surroundings occasion, as inflammable and explosive occasions such as mine ventilations.
3, the utility model compact structure volume is little, simple to operate, is convenient to install; Lightweight, conveniently moving is also easy to carry.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the organigram of pneumatic sparger in the utility model.
Reference character in figure is: 1 pneumatic sparger; 2 water conservancy diversion Diffusers; 3 pressurized air air supply openings; 4 annular chambers; 5 annuluss; 6 annular chamber sidewalls; 7 air suction inlets; 8 framies; 9 air ejiction openings.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail:
The super pneumatic fan of one as shown in Figure 1 and Figure 2 comprises pneumatic sparger 1 and water conservancy diversion Diffuser 2, can disperse or collect the waste gas in industry, detest cost-effectively, or some industrial light materials.
As shown in Figure 2, pneumatic sparger 1 adopts both ends open, the inner frame 8 for cavity structure, annular chamber 4 is built-in with in frame 8, and between annular chamber 4 and frame 8 internal cavity structures between be separated with annular chamber sidewall 6, make only to leave annulus 5 between annular chamber 4 and frame 8 internal cavity structures and circulate.
