Abstract
The invention discloses a venturi mist sprayer. The venturi mist sprayer comprises an air inlet pipeline, a motor, an impeller, a venturi shrinking pipeline, a venturi throat pipe and a venturi diffusion pipeline, wherein the impeller and the venturi shrinking pipeline are mounted in the air inlet pipeline; the venturi shrinking pipeline is funnel-shaped; one end, with relatively small diameter, of the venturi shrinking pipeline stretches out of the air inlet pipeline and is connected with one end of the venturi throat pipe; one end face, with great diameter, of the venturi shrinking pipeline faces the impeller; a micro-mist nozzle is mounted at one end, with the small diameter, of the venturi shrinking pipeline; the impeller is connected with the motor; one end of the venturi diffusion pipeline is connected with the other end of the venturi throat pipe; and the other end of the venturi diffusion pipeline is provided with a secondary nozzle. According to the venturi mist sprayer disclosed by the invention, the dust falling and dust inhibition effects are effectively improved.
Description
Technical field
The present invention relates to treating flour dust equipment technical field, especially venturi sprayer.
Background technology
Traditional sprayer has been delivered to dirt region by blower fan system for forming water fog particle, and drops with dust collision cohesion
Dirt acts on, and due to single water fog particle finite volume, area coverage is limited, limits the effect of traditional sprayer depositing dust dust suppression.
Content of the invention
The present invention is directed to the deficiencies in the prior art, proposes venturi sprayer, effectively increases the effect of depositing dust dust suppression.
In order to realize foregoing invention purpose, present invention offer technical scheme below:
Venturi sprayer, including intake stack, motor, impeller, venturi Contraction Ducts, Venturi throat and venturi
Diffuser,
Described impeller and described venturi Contraction Ducts are arranged in described intake stack, and described venturi Contraction Ducts are
Infundibulate, its diameter small end is stretched out described intake stack and is connected with described Venturi throat one end, and it is relatively large in diameter end face
To described impeller, in described venturi Contraction Ducts diameter less one end, Fine-fog nozzle is installed, described impeller and described electricity
Machine connects,
Described venturi diffuser one end is connected with the other end of described Venturi throat, in described venturi anemostat
On the other end in road, secondary nozzle is installed.
Further, described Venturi throat can adjust Venturi throat for cross sectional dimensions.
Further, described venturi diffuser is infundibulate, and the less one end of its diameter is with described Venturi throat even
Connect, it is relatively large in diameter on one end and is provided with secondary nozzle.
Venturi sprayer of the present invention, and though by the combination of venturi Contraction Ducts and relative configurations it is achieved that right
Size is larger or the limited sedimentation of less dust, substantially increases the effect of dust suppression depositing dust.
Brief description
Fig. 1 is the internal structure schematic diagram of venturi sprayer of the present invention.
Specific embodiment
Describe the present invention below in conjunction with the accompanying drawings, the description of this part is only exemplary and explanatory, should not
There is any restriction effect to protection scope of the present invention.
Venturi sprayer as shown in Figure 1, including intake stack 2, motor 3, impeller 4, venturi Contraction Ducts 5, literary composition
Trunnion 7 and venturi diffuser 8 in mound,
Collecting cover 1 is installed in intake stack port, and impeller 4 and venturi Contraction Ducts 5 are arranged in intake stack 2, civilian mound
In Contraction Ducts 5 be infundibulate, its diameter small end stretched out intake stack 2 and is connected with Venturi throat 7 one end, and it is relatively large in diameter
One end, towards impeller 4, is provided with Fine-fog nozzle 6 in the less one end of venturi Contraction Ducts 5 diameter, Fine-fog nozzle 6 has some
Individual, depending on number can be according to actual conditions, around the distribution of this end, impeller 4 is connected with motor 3,
Venturi diffuser 8 one end is connected with the other end of Venturi throat 7, another in venturi diffuser 8
Secondary nozzle 10 is provided with end it is also possible to be arranged on venturi diffuser 8 in wind pipe 11, and installation outlet rectification
Cover 9, secondary nozzle 10 is arranged on wind pipe 11 end.
Venturi throat 7 can adjust Venturi throat 7 for cross sectional dimensions, and adjustable Venturi throat 7 passes through to adjust it
Two bolts 71 that both sides are inserted radially in Venturi throat 7 screw in horizontal in the deep regulation Venturi throat 7 of Venturi throat 7
The size in section, and then realize the regulation of wind speed and ventilation.
Venturi diffuser 8 is infundibulate, and the less one end of its diameter is connected with Venturi throat 7, and it is relatively large in diameter one
Secondary nozzle 10 is provided with end.
Regulation chute 12, this regulation chute 12 and slide bearings are had on intake stack 2 and wind pipe 11
13 are slidably matched.
During use, the present invention is placed in and treats depositing dust region, start motor 3 impeller 4 and rotate, by the sky with dust
Pneumatic transmission enters venturi Contraction Ducts 5, and then passes through Venturi throat 7, flows out pipeline through venturi diffuser 8.Air passes through
During the venturi Contraction Ducts 5 that area of section is gradually reduced, air compresses, and air pressure increases by force and flow velocity also becomes big therewith.Here
During, produce a vacuum in the entrance of Venturi throat 7, cause the internal Fine-fog nozzle 6 of venturi Contraction Ducts 5 to produce
Unboiled water mist is inhaled in Venturi throat 7, and the particle that water smoke shrinks, spreads increase in the air together with compressed air is less
Dust forms cloud particle with water smoke collision, realizes the depositing dust dust suppression to the less dust of particle, then is sprayed by secondary nozzle,
Make cloud particle growth, dust and droplet collision rift can make single droplet accommodate more juicy, and after ejection, single droplet covers
Capping amasss the depositing dust dust suppression it is achieved that the dust larger to particle.
Venturi sprayer of the present invention, and though by the combination of venturi Contraction Ducts and relative configurations it is achieved that right
Size is larger or the limited sedimentation of less dust, substantially increases the effect of dust suppression depositing dust.
