Abstract
The invention relates to a rotating-in type dual-inlet medium ejector which comprises a pipe body and a nozzle connected to the pipe body in a sleeved mode. The pipe body comprises a vacuum chamber, a nozzle hole, a venturi tube and two tangential branch tubes, wherein the nozzle hole, the venturi tube and the two tangential branch tubes are respectively communicated with the vacuum chamber in a sealed mode. The nozzle is connected into the nozzle hole in a sleeved mode. The nozzle and the venturi tube are coaxially located at the two ends of the vacuum chamber. The tangential branch tubes are tangent to the side circumference of the vacuum chamber. The two tangential branch tubes are of a central symmetry structure by using the axis of the venturi tube as the center. According to the rotating-in type dual-inlet medium ejector, the two tangential vacuum tubes tangent to the side circumference of the vacuum chamber are arranged, and the function that steam can be sucked by and enter the vacuum chamber in a rotating mode is achieved due to the structure, so that different kinds of steam enter the vacuum chamber through the different branch tubes and are mixed sufficiently inside the vacuum chamber through rotation, and meanwhile the flow direction of flow media is not affected by the two branch tubes of the central symmetry structure.

Detailed description of the invention
The present invention is further detailed explanation in conjunction with the accompanying drawings and embodiments now, and these accompanying drawings are the schematic diagram of simplification, and basic structure of the present invention is only described in a schematic way, and therefore it only shows the formation relevant with the present invention.
As Fig. 1, Fig. 2, shown in Fig. 3, the two entrance medium injection devices of screw-in, comprise body 1 and threaded nozzle 2, body 1 is provided with vacuum chamber 3, screwed hole 4, Venturi tube 5 and two two tangential arms 6, wherein the coaxial connection of screwed hole 4 and Venturi tube 5 is at vacuum chamber two ends, nozzle 2 is sheathed to be connected in nozzle bore 4, in 3 side weeks of vacuum chamber, tangential arm 6 is tangent with the side week of vacuum chamber 3, two tangential arms 6 are the centrosymmetric structures centered by Venturi tube 5 axis, then the steam simultaneously entering in vacuum chamber 3 from two tangential arms 6 can mix along vacuum chamber 3 inwall rotations, extend like this residence time of steam at vacuum chamber 3, and two strands of steam of rotation can better mix.
Threaded nozzle 2 is provided with the flat pipe portion 7 that is positioned at screwed hole 4 outsides and the tip 8 that is positioned at vacuum chamber 3, the structural design of tip 8 can ensure the air in vacuum chamber 3, fluid media (medium) and steam etc. flow to Venturi tube 5 smoothly, and can not produce inhibition, tip 8 ends are provided with and the spout 9 of putting down pipe portion 7 inner chambers and being communicated with, the inner diameter of flat pipe portion 7 is far longer than the inner diameter of spout 9, contribute to like this to improve the spouting velocity of fluid media (medium) in threaded nozzle 2, screwed hole 4 internal thread connecting thread nozzles 2, flat pipe portion 7 outsides are with external screw thread, screwed hole 4 inwalls are with internal thread, internal thread mates with external thread structure, threaded nozzle 2 can move at screwed hole 4 inside spins along its axis, rotation threaded nozzle 2, threaded nozzle 2 just can move forward and backward along its axis in screwed hole 4, there is crosspoint 14 with tangential arm 6 axis in threaded nozzle 2 axis, spout 9 be positioned on crosspoint 14 or 14 left and right sides, crosspoint threaded nozzle 2 axis on, when spout 9 positions of the threaded nozzle 2 that can move and the relative position in crosspoint 14 change, the fluid media (medium) of ejection is also different to the vacuum swabbing action in vacuum chamber 3 at a high speed, therefore, by regulating the vacuum of the adjusting vacuum chamber 3 that spout 9 and the relative position in crosspoint 14 just can be relative.
Venturi tube 5 is provided with compression section 10, larynx section 11 and diffuser 12 successively along its axis, compression section 10 vacuum chamber 3 that is tightly connected, compression section 10 and vacuum chamber 3 junction internal diameters are greater than the junction internal diameter of itself and larynx section 11, and expansion segment 12 free end internal diameters are greater than the junction internal diameter of itself and larynx section 11.Fluid media (medium) enters Venturi tube 5 with certain speed from compression section 10, because the compression section 10 cross section radiuses of air stream warp dwindle gradually, the flow velocity of fluid media (medium) increases thereupon, air velocity maximum while arriving larynx section 11, from Bernoulli equation, air velocity is inversely proportional to air pressure herein, it is the air pressure minimum of larynx section 11, the direction top rail section radius that air-flow is flowed through at diffuser 12 becomes large gradually, fluid media (medium) flow velocity diminish gradually slow down and, steam and air that last fluid media (medium) drives flow out Venturi tube 5, Venturi tube 5 has ensured fluid media (medium), steam and air all can not flow backwards as in vacuum chamber 3.
Screwed hole 4 free ends, Venturi tube 5 free ends, two tangential arm 6 free ends and flat tube section 7 free ends are equipped with being tightly connected along 13 of turning up along its circumferential edge, and this kind of structure contributes to its be tightly connected external pipe or equipment.Vacuum chamber 3 inwalls are globoidal structure, contribute to the flowing and mixing in vacuum chamber 3 such as steam or air, also contribute to air-flow, medium etc. to flow out smoothly vacuum chamber 3.
The present invention in use, fluid media (medium) enters at a high speed the inner chamber of threaded nozzle 2 from threaded nozzle 2, and spray with higher flow velocity from the very little spout 9 of internal diameter, flow velocity while entering vacuum chamber 3 due to fluid media (medium) is very high, under the effect of fluid media (medium), air in vacuum chamber 3 can be taken out of and enter Venturi tube 5 by fluid media (medium), in vacuum chamber 3, be now negative pressure, the swabbing action that steam in tangential arm 6 can be produced by the negative pressure of vacuum chamber 3 enters vacuum chamber 3, and can be aspirated and produce with it certain immixture by fluid media (medium), between mixed process fluid media (medium) and steam, can produce friction, heat exchange or even chemical reaction, fluid media (medium), steam and the air mixing flows at a high speed the compression section 10 of Venturi tube 5, along with its internal diameter diminishes gradually, it is large that the flow velocity of mixture becomes gradually, while arriving larynx section 11, it is maximum that its flow velocity reaches, then mixture enters diffuser 12, diffuser 12 internal diameters become large gradually, the flow velocity of mixture diminishes gradually, final mixture leaves Venturi tube 5 and enters in other equipment, the acceleration of Venturi tube 5 to mixture flow and slow down and usedly ensured that mixture can not produce adverse current, and also contribute to the generation of the processes such as the mixing between mixture.
Be enlightenment according to desirable embodiment of the present invention above, by above-mentioned description, related personnel can, not departing from the scope of this invention technological thought, carry out various change and amendment completely.The technical scope of this invention is not limited to the content on description, must determine technical scope according to claim scope.
