The object of the present invention is achieved like this: it is made up of jet units 14 and suction unit 15, and suction unit 15 is arranged on the vertical part of jet units 14.
The present invention also has following technical characterictic:
(1) described jet units 14 comprises jet pipe 3, tensimeter 10, adjustable nozzle 8 and purging valve 11, the horizontal component of jet pipe 3 is provided with dress tensimeter 10 and purging valve 11, jet pipe 3 one ends are installed adjustable nozzle 8, between jet pipe 3 and the adjustable nozzle 8 for being threaded or clamp connection.
(2) described suction unit 15 comprises air suction pipe 2, regulating handle 1, flange chassis 4, adjustable shower nozzle 8, scale 9, rigidity packing ring 12, blind flange 6 and erecting stage 13, air suction pipe 2 passes jet pipe 3 and erecting stage 13 is set at the place of passing and is provided with in the accent and installs, air suction pipe 2 tops are provided with regulating handle 1 and scale 9, supporting different size rigidity packing ring 12 and blind flange 6, sealing between blind flange 6 and the air suction pipe 2.
A kind of adjustable jet aeration device of the present invention, compare with traditional ejector, devices such as air chamber, mixing tube, diffuser tube have not only been saved, and it is simple in structure, can change adjusting flexibly, in actual installation and operation debugging, can be according to running condition and each spot size of needs setting device.Installation and Debugging are convenient, can effectively avoid unexpected waste.
(4) description of drawings
Fig. 1 is the view of installing and using of the present invention;
Fig. 2 is a structural representation of the present invention;
Fig. 3 is a partial enlarged drawing of the present invention;
Fig. 4 is a nozzle sectional view of the present invention.
(5) embodiment
The present invention will be further described for example below in conjunction with accompanying drawing.
Embodiment 1.In conjunction with Fig. 2, a kind of adjustable jet aeration device of the present invention, it is made up of jet units (14) and suction unit (15), and suction unit (15) is arranged on the vertical part of jet units (14).
The present invention also has following technical characterictic:
Described jet units (14) comprises jet pipe (3), tensimeter (10), adjustable nozzle (8) and purging valve (11), the horizontal component of jet pipe (3) is provided with dress tensimeter (10) and purging valve (11), jet pipe (3) one ends are installed adjustable nozzle (8), between jet pipe (3) and the adjustable nozzle (8) for being threaded or clamp connection.
Described suction unit (15) comprises air suction pipe (2), regulating handle (1), flange chassis (4), adjustable shower nozzle (8), scale (9), rigidity packing ring (12), blind flange (6) and erecting stage (13), air suction pipe (2) passes jet pipe (3) and erecting stage (13) is set at the place of passing and is provided with in the accent and installs, air suction pipe (2) top is provided with regulating handle (1) and scale (9), supporting different size rigidity packing ring (12) and blind flange (6), sealing between blind flange (6) and the air suction pipe (2).
Embodiment 2, in conjunction with Fig. 2, a kind of adjustable jet aeration device of the present invention, described jet pipe (3) one termination liquid-inlet pipes, liquid is gone into jet pipe by the liquid-inlet pipe high speed flow, at jet pipe vertical portion branch air suction pipe (2) is housed, air suction pipe (2) passes jet pipe (3) and is provided with air suction pipe erecting stage (13) at the place of passing, and be provided with in the accent and install, air suction pipe (2) top is provided with regulating handle (1), can contrast scale (9) and accurately regulate the air suction pipe height up and down.Can regulate the air suction pipe bore according to different size rigidity packing ring (12) and blind flange (6), packing (5) with spunyarn, asbestos material between blind flange (6) and the air suction pipe (2) twines sealing, jet pipe (3) the other end is equipped with adjustable nozzle (8), by install the different size nozzle can adjust nozzle diameter and and air suction pipe between spacing e.During use this device is installed in the injection circulation reactor top, as the structure of representing among the figure, liquid is gone into jet pipe by the liquid-inlet pipe high speed flow, quickens to inject reactor at the nozzle place, produces negative pressure by the current high-velocity jet, and a large amount of air are sucked by air suction pipe.Under the acting in conjunction of current and air-flow, make the nozzle below form high speed turbulent shear district, be to suck air dispersion to become small bubbles.But lean out nozzle length by regulating handle up-down adjustment air suction pipe.Air suction pipe is by the common fixing seal of flange base (4), blind flange (6) and packing (5).Adjust aligning gear, make air suction pipe centering, guarantee good air-breathing and dispersion effect.
