Abstract
The invention relates to improvement on an oxygenation aerator in water treatment. In order to overcome the technical defects of a single-mixing-nozzle jet aerator which is used at present, the invention provides a bushing type jet aerator. The bushing type jet aerator comprises an air inlet pipe and a water inlet pipe, and is characterized in that the water inlet pipe is positioned in the air inlet pipe and is concentrically sleeved, wherein the outer wall of the air inlet pipe is provided with a plurality of outer nozzles which are arranged perpendicular to the air inlet pipe; the tail parts of the outer nozzles are communicated with the air inlet pipe; the parts, corresponding to the outer nozzles, of the water inlet pipe are provided with inner nozzles; the tail parts of the inner nozzles are communicated with the water inlet pipe; the inner nozzles extend into the outer nozzles to form concentric nesting; an air inlet passage is formed in a gap between the inner nozzles and the tail parts of the outer nozzles; an air-liquid mixing cavity is formed in a cavity between the front ends of the inner nozzles and the outer nozzles. The bushing type jet aerator is convenient to mount and has a compact structure, so that the floor area of the aerator is greatly reduced.
Description
Technical field
The present invention is to the improvement of aerator for oxygenation in water treatment, relates in particular to a kind of compact construction, the telescoping jet aerator of nozzle quantity can be set flexibly.
Background technology
The aerator of prior art mainly contains two kinds of forms, a kind of for the circular plates formula spray type aerating device of a plurality of mixing nozzles, such as Chinese patent CN2700318, CN201447385U, CN201634512U, CN201908001U etc. are around set; A mixing nozzle spray type aerating device, such as Chinese patent CN2825632, CN101993145A, CN202121525U etc.The structure of single mixing nozzle spray type aerating device comprises water inlet pipe, inlet pipe and nozzle, between water inlet pipe and inlet pipe, air storage chamber is set, and after water inlet pipe water inlet, the air in water and air storage chamber forms to shear and penetrates through nozzle in nozzle.This list mixing nozzle spray type aerating device is single nozzle structure, utilizes water inlet pipe to be fixedly connected with total inlet pipe with water inlet manifold with the flange in inlet pipe, and it installs complicated, and due to air storage chamber, it takies larger space.
Summary of the invention
For overcoming the existing above-mentioned technological deficiency of single mixing nozzle spray type aerating device of current use, the invention provides a kind of telescoping jet aerator.
The technical solution used in the present invention is: telescoping jet aerator, comprise inlet pipe and water inlet pipe, it is characterized in that: described water inlet pipe is positioned at inlet pipe inner concentric fit, on the outer wall of inlet pipe, be provided with several and the vertically disposed outer nozzle of inlet pipe, outer nozzle afterbody and inlet pipe connect; On water inlet pipe position corresponding to outer nozzle, be provided with inner nozzle, the afterbody of inner nozzle and water inlet pipe connect, inner nozzle is deep into the concentric fit of the inner formation of outer nozzle, space between inner nozzle and outer nozzle afterbody forms induction trunk, and the cavity between inner nozzle front end and outer nozzle forms gas-liquid mixed chamber.
The degree of depth that described inner nozzle gos deep into outer nozzle is the 1/8-1/4 of outer nozzle length.
Described water inlet pipe is positioned at the end-enclosed of inlet pipe inside.
End and the water inlet pipe closed front of described inlet pipe fit end.
Between described water inlet pipe and inlet pipe, be provided with some back up pads.
The feed-water end of described water inlet pipe and the inlet end of inlet pipe are respectively equipped with mounting flange.
This telescoping jet aerator adopts after said structure, and the length of aerator and nozzle quantity can freely arrange according to fabricating yard, and it is easy for installation, compact construction, adopt the direct air feed of inlet pipe, omitted air storage chamber structure, the area occupied of aerator is greatly reduced.
Accompanying drawing explanation
The structure sectional view that accompanying drawing 1 is this aerator.
Accompanying drawing 2 be in accompanying drawing 1 A-A to sectional view.
Embodiment
Below in conjunction with drawings and Examples, the present invention will be further described.
As shown in Figure 1, telescoping jet aerator, comprises inlet pipe 1 and water inlet pipe 2, and water inlet pipe 2 is positioned at inlet pipe 1 inner concentric fit, and one end that water inlet pipe 2 is positioned at inlet pipe 1 outside is feed-water end 3, and its one end sealing that is positioned at inlet pipe 1 inside forms closing end 4.End and the water inlet pipe closed front of inlet pipe 1 and water inlet pipe fit, its other end forms inlet end 5.
As shown in accompanying drawing 1, accompanying drawing 2, on the outer wall of inlet pipe, be provided with and the vertically disposed outer nozzle 6 of inlet pipe 1.As shown in Figure 2, outer nozzle afterbody and inlet pipe connect.
As shown in accompanying drawing 1 and accompanying drawing 2, on water inlet pipe position corresponding to outer nozzle, be provided with inner nozzle 7.As shown in Figure 2, the afterbody of inner nozzle 7 and water inlet pipe 2 connect, inner nozzle 7 is deep into inner concentric fit, the space formation induction trunk 8 between inner nozzle 7 and outer nozzle 6 afterbodys, the cavity formation gas-liquid mixed chamber 9 between inner nozzle front end and outer nozzle of forming of outer nozzle 6.
As shown in Figure 1, show in the present embodiment outer nozzle in two covers, during actual fabrication, according to place installation situation, a plurality of supporting inner nozzles and outer nozzle can be set.
As shown in accompanying drawing 1, accompanying drawing 2, for strengthening the strength of joint between inlet pipe 1 and water inlet pipe 2, between water inlet pipe and inlet pipe, be provided with some back up pads 10.
As shown in Figure 1, the feed-water end of water inlet pipe and the inlet end of inlet pipe be respectively equipped with for the fixing mounting flange 11 of water inlet manifold, total inlet pipe.
During use, inlet pipe 1 and water inlet pipe 2 are connected with total inlet pipe, water inlet manifold by mounting flange 11 respectively, current with pressure are ejected into outer nozzle 6 inside through inner nozzle 7, in current ejection, gas enters into outer nozzle inside through induction trunk 8, current and air be interior formation shearing in gas-liquid mixed chamber 9, finally by outer nozzle 6, is penetrated and is reached aeration effect.
For making there is sufficient shear history in air-flow, the current gas-liquid mixed chamber 9 in outer nozzle, during making, inner nozzle gos deep into the degree of depth of outer nozzle and should control between the 1/8-1/4 into outer nozzle length.
Certainly, above-mentioned is not limitation of the present invention for example, the present invention be also not limited to above-mentioned for example, the modification of making in essential scope of the present invention, replacement, increase or delete all and should belong to protection scope of the present invention.
