Abstract

The utility model discloses an air amplifier, this air amplifier include at least one pressure connection, shell body, interior casing, stator, the casing was outer and pass through threaded connection including the shell body cover was established, form the annular chamber between interior casing and the shell body, arrange pressure connection on the shell body, the one end of interior casing sets up the slope lateral wall, one side that pressure connection was kept away from to the annular chamber is provided with the ring nozzle, arrange the stator in the annular chamber. The utility model discloses a many air inlets inputs compressed air, make during compressed air can evenly input the ring nozzle, improved the even degree of suction.

Description

A kind of air amplifier
Technical field
The utility model relates to dust removal by ventilation field, is specifically related to a kind of air amplifier.
Background technique
Air amplifier is the pneumatic equipment for aspirating waste gas, smog, dusty gas etc., and it is using pressurized air as power, has compact structure, safeguards simply, is easy to the advantages such as control, extensive use in industrial field.Existing air amplifier also exists following deficiency: (1) aspirates uneven, the waste gas be sucked, smog, dusty gas etc. have escape phenomenon (2) along with the increase of volume, suction capactity sharply reduces, suction capactity can only be ensured by increasing pressurized air air inflow, causing energy waste.
Model utility content
In view of this, main purpose of the present utility model is to provide a kind of air amplifier.
For achieving the above object, the technical solution of the utility model is achieved in that
The utility model embodiment provides a kind of air amplifier, this air amplifier comprises at least one air input joint, frame, inner housing, stator, it is outer and be threaded connection that described frame is set in inner housing, forms annular chamber between described inner housing and frame; Described frame arranges air input joint, and one end of inner housing arranges sloped sidewall, and described annular chamber is provided with ring nozzle away from the side of air input joint, and described stator is arranged in annular chamber.
In such scheme, the quantity of described air input joint is three, and is evenly arranged frame is circumferential.
In such scheme, described annular chamber is provided with seal ring near air input joint side.
In such scheme, described frame is connected with locking ring by screw thread.
In such scheme, described stator is helical.
Compared with prior art, the beneficial effects of the utility model:
(1) the utility model have employed many suction ports input compressed-air, pressurized air is evenly inputted in ring nozzle, improves the uniformity coefficient of suction.
(2) the compressed-air actuated direction that suction port inputs by stator of the present utility model is adjusted to axially from radial direction, reduces drag losses, improves static pressure, significantly enhance compressed-air actuated utilization ratio.
Accompanying drawing explanation
Fig. 1 provides a kind of structural representation of air amplifier for the utility model embodiment;
Fig. 2 is the left view of Fig. 1.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
The utility model embodiment provides a kind of air amplifier, as shown in Figure 1, 2, this air amplifier comprises at least one air input joint 2, frame 7, inner housing 9, stator 10, it is outer and be threaded connection that described frame 7 is set in inner housing 9, forms annular chamber 8 between described inner housing 9 and frame 7; Described frame 7 arranges air input joint 2, and one end of inner housing 9 arranges sloped sidewall 11, and described annular chamber 8 is provided with ring nozzle 4 away from the side of air input joint 2, arranges stator 10 in described annular chamber 8.
The quantity of described air input joint 2 is three, and is evenly arranged frame 7 is circumferential, quantity the increasing along with air amplifier volume of described air input joint 2, its quantity be 4 even more.
Described annular chamber 8 is provided with seal ring 5 near air input joint 2 side.
Described frame 7 is connected with locking ring 3 by screw thread.
Described stator 10 is helical.
Workflow of the present utility model:
Pressurized air enters in annular chamber 8 by air input joint 2, through continuous print spiral motion, flow direction is adjusted to axially from radial direction under the effect of stator 10, after this pressurized air forms high-speed jet by ring nozzle 4, high-speed jet is close to sloped sidewall 11 and is flowed, formation negative pressuren zone, cavity place outside inner housing 9, thus attract a large amount of waste gas, smog, dusty gas etc. around to pour in from intake grill 6, waste gas, smog, dusty gas etc. and high-speed jet converge forms high speed afterwards, the air-flow of high power capacity flows out from exhaust outlet 1.
The above, be only preferred embodiment of the present utility model, is not intended to limit protection domain of the present utility model.
