Description
Technical field
The utility model relates to pneumatic element, refers to especially a kind of air amplifier.
Background technique
Air flow amplifier is the pneumatic element that one is widely used in industrial field, utilization " Koln reaches " effect, air flow amplifier can convert small flow high pressure pressurized air to low pressure and mass flow air-flow, inlet end at air flow amplifier produces underbalance effect, produce a vacuum low-pressure district, this district has extremely strong Incision Machine's, can be used for Pneumatic vacuum suction solid granulates and oil fume vapor; Be outlet side at the other end of air flow amplifier, compressed-air actuated initial air-flow can converge mass air flow around, at a high speed, the air-flow of high power capacity flows out from the outlet side of air flow amplifier, can substitute the cooling and removal moisture drying for air of traditional blower fan or fan.
And air amplifier more be the injection for air, steam, dust etc., it is powerful not that reason is mainly guiding injection power; The spray of its gap is generally 0.05mm left and right on the other hand, and the relatively large material of the injection particle diameter spout that easily gaps stops up, and uses inconvenience.And as the disclosed air jetting amplifier of patent that the patent No. is 201020282338.8, its annulus determines chinky altitude by convex tendon, the Machining of Curved Surface difficulty of convex tendon is large, and manufacture cost is higher.
Model utility content
The utility model proposes a kind of air amplifier, its injection power is strong, is difficult for stopping up, and difficulty of processing is little.
The technical solution of the utility model is achieved in that a kind of air amplifier, comprise the frame of built-in injection passage, one end of described frame is air intake, the other end of frame is delivery outlet, described delivery outlet extends internally and surrounds the annular chamber inwall of annular chamber for frame, the compressed air inlet that is communicated with annular chamber is set on frame, air flow mouth is set one time between the wall body at the bottom of annular chamber inwall and air intake place, on annular chamber inwall, is provided with secondary gas flow mouth.
Pressurized air is filled with from compressed air inlet, owing to being also provided with secondary gas flow mouth except an air flow mouth, in the time that air flow stream is crossed secondary gas flow mouth, pressurized air in annular chamber is further produced to the pulling force of outwards inhaling, impel stronger the discharging from secondary gas flow mouth of pressurized air, flowing velocity flows through injection vias inner walls quickly, injection channel center forms the more region of low pressure, thereby attract a large amount of surrounding atmosphere to pour in from air intake, formed the injection passage that more single air flow mouth attraction force is stronger.
In the time that an air flow mouth stops up, secondary gas flow mouth still can be realized air ejection, can produce the suction to obstruction, is conducive to air flow mouth of obstruction sucking-off; In the time that secondary gas flow mouth stops up in like manner.
Further, the ramp way that described secondary gas flow mouth is entrance point towards air intake, outlet end towards delivery outlet, the air flow mouth of inclination is conducive to the air-flow delivery outlet that leads.
Described injection passage is tapered channel, and injection passage is greater than the diameter of the other end towards the diameter of air intake one end, is the vias inner walls of tapering, is conducive to form and be close to the fluid of inwall after pressurized air penetrates, and is conducive to the suction of outside air etc.
Described secondary gas flow mouth extends and protrudes towards the port of injection passage, is conducive on the one hand guiding into of pressurized air stream, and the material sucking is in addition difficult for entering secondary gas flow mouth.In like manner, described air intake extends and protrudes along air incoming direction near one end of an air flow mouth.
This programme utilizes the structure of pressurized air secondary accelerated release in vitro, has realized the amplification of secondary air energy, can effectively improve inlet capacity and conveying capacity, also has the not susceptible to plugging advantage of air flow mouth, makes its use field more broad, as the suction of injection raw material.
Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described 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, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the cross-sectional view of a kind of air amplifier of the utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment who obtains under creative work prerequisite, all belong to the scope of the utility model protection.
A kind of air amplifier, as shown in Figure 1, comprise the frame 1 of built-in injection path 10, one end of described frame 1 is air intake 6, the other end of frame 1 is delivery outlet 5, and described delivery outlet 5 extends internally and surrounds the annular chamber inwall 4 of annular chamber 2 for frame 1, and the compressed air inlet 3 that is communicated with annular chamber 2 is set on frame 1, air flow mouth 7 is set one time between the wall body at the bottom of annular chamber inwall 4 and air intake 6 places, on annular chamber inwall 4, is provided with secondary gas flow mouth 8.
Pressurized air is filled with from compressed air inlet 3, owing to being also provided with secondary gas flow mouth 8 except an air flow mouth 7, in the time that air flow stream is crossed secondary gas flow mouth 8, pressurized air in annular chamber 2 is further produced to the pulling force of outwards inhaling, impel stronger the discharging from secondary gas flow mouth 8 of pressurized air, flowing velocity flows through injection path 10 inwall quickly, in injection path 10, be formed centrally the more region of low pressure, thereby attract a large amount of surrounding atmosphere to pour in from air intake 6, formed the injection path 10 that more single air flow mouth attraction force is stronger.This programme utilizes the structure of pressurized air secondary accelerated release in vitro, has realized the amplification of secondary air energy, can effectively improve inlet capacity and conveying capacity, makes its use field more broad, as the suction of injection raw material.
