Embodiment
Embodiment, as shown in Figure 1: Jet injector, comprises the first mixing chamber 10 being positioned at left side and the second mixing chamber 20 being positioned at right side.
Concretely:
The left side of this first mixing chamber 10 is provided with the first suction port 11, right side is provided with the first trunnion 12, and the neutral position in this first mixing chamber 10 is provided with the first jet 13 of opening towards the right side.The left side of this second mixing chamber 20 is provided with the second suction port 21, right side is provided with aux. venturi 22, and the neutral position in this second mixing chamber 20 is provided with the second nozzle 23 of opening towards the right side.
This first trunnion 12 is connected by a transition tube 30 with this second suction port 21.This transition tube 30 has the conical cavity that left end is large, right-hand member is little, and this conical cavity internal surface has spiral chute 31.That is, this spiral chute 31 is directly molded on the sidewall of this conical cavity.In other words, the cell body taken shape on the sidewall of this conical cavity extends forward in the shape of a spiral thus forms this spiral chute 31.
More specifically:
This first jet 13 is connected with supply pipe 40, and this second nozzle 23 is connected with a connecting tube 50, and the other end of this connecting tube 50 is communicated with on the sidewall of this supply pipe 40.This first suction port 11 is connected with suction tube 60.Diffusing opening 70 is connected with on the right side of this aux. venturi 22.Namely, spray to the right in this first jet 13 and this second nozzle 23 after a kind of medium enters from this supply pipe 40, and another kind of medium is inhaled into from this suction tube 60, then two media sprays from this diffusing opening 70 after mixing in the first mixing chamber 10 and the second mixing chamber 20.Certainly, this first mixing chamber 10 is identical with the inner chamber profile of this second mixing chamber 20, to guarantee the medium rapid release pressure after the pressurizing sprayed in this second mixing chamber 20.
Like this, because two media have passed through secondary transmission, thus the working efficiency of this Jet injector is added.Meanwhile, medium have passed through and again pressurizes in transition tube 30, and under the effect of this spiral chute 31, mixed medium is rotated and advances, further increase the efficiency of this Jet injector.
Continue to optimize:
The pitch linear narrowing of this spiral chute 31.That is, the spacing of the cell body of this spiral chute 31 progressively reduces, thus the rotational speed of the medium flow through is increased gradually and pressure also progressively increases, thus further increases the efficiency of Jet injector.
This connecting tube 50 is provided with compression pump 51.So, this second nozzle 23 spray the speed of medium and blowing force and be all greater than the medium that this first jet 13 sprays, guarantee that the medium that this second nozzle 23 sprays only can increase Jet injector efficiency and can not play reaction.
Position in this second mixing chamber 20 between this second suction port 21 and this second nozzle 23 is provided with the little umbrella-shaped baffle of left end 80.Like this, guarantee that medium passes through at the avris of this second nozzle 23, reduce this second nozzle 23 pairs of media and flow through the reaction caused.
This transition tube 30 adopts non-near magnetic material to prepare, and this transition tube 30 outside is provided with magnet 32.Namely, when medium is for having the media such as metal suspension particle, guarantee that medium is when flowing through this transition tube 30, medium is under the suction of this magnet 32, the inwall that as much as possible against this transition tube 30 flows through, and has played the effect of conical cavity and this spiral chute 31 more fully.
The foregoing is only the preferred embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every utilize specification of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
