Abstract

The utility model discloses a jet aeration stirrer. The jet aeration stirrer comprises a gas mixing chamber, wherein a joint flange is connected to the front side of the gas mixing chamber; a diffusion tube is connected to the back side of the gas mixing chamber; a cluster orifice plate is arranged in the gas mixing chamber; a plurality of jet holes are formed in the cluster orifice plate; at least one air manifold is arranged on the front side of the cluster orifice plate and communicated with air. Due to the adoption of the plurality of jet holes in the cluster orifice plate, a flow speed provided by a single nozzle is increased; meanwhile, air is filled through a plurality of small-diameter air manifolds, so that a gas-liquid ratio is effectively increased, and thus the oxygen dissolving efficiency is improved; due to high flow speeds of the jet holes, a larger amount of water can be dragged to flow and increase the flow speed in a tank, so that a stirring effect is improved.

Description

A kind of jet-flow aeration agitator

Technical field

The utility model relates to jet-flow aeration agitator.

Background technology

Existing jetting type aeration agitation device all utilizes Wen Tuoli pipe principle, the negative pressure producing by aperture because of current at place, aperture, by the current in Chu Yu aperture, air intake aperture produce one vertical and his like to, make air when entering water body, be cut into small bubbles, enter the effect that water body reaches aeration agitation.But because of the aperture of recirculated water larger, cannot provide higher flow velocity to reach larger negative pressure value, to introduce larger air, simultaneously because the flow velocity of cutting is little, therefore the density of bubble is not enough, make the dissolved oxygen efficiency lifting that cannot effectively make progress, and need be by the mode of external force, dwindle the bubble of air, to improve dissolved oxygen efficiency, thereby limit the purposes of jetting type aeration agitation device.

Utility model content

Technical problem to be solved in the utility model is just to provide a kind of jet-flow aeration agitator, increases dissolved oxygen efficiency and mixing effect.

For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of jet-flow aeration agitator, comprise mixing chamber, described mixing chamber front side connects faying flange, rear side connects diffuser tube, in described mixing chamber, be provided with a bundle holes oralia, described bundle holes oralia is provided with a plurality of fluid orifices, and described bundle holes oralia front side is provided with at least one air manifold and air communication.

Preferably, described air manifold end connects an air chamber, and described air chamber is provided with an air inlet supervisor and is communicated with air amount with atmosphere.

Preferably, described bundle holes oralia front side is also provided with at least one air manifold and is communicated with liquor tank.

Preferably, described diffuser tube is tubaeform, and described diffuser tube middle part is along being circumferentially evenly equipped with 4～6 pod apertures.

Preferably, described a plurality of fluid orifices evenly arrange around bundle holes oralia center, described fluid orifice flare.

The utility model utilizes a plurality of fluid orifices on bundle holes oralia, improve the flow velocity that single nozzle can provide, simultaneously, utilize the air manifold introducing air of many small-bores, effectively to improve vapour-liquid ratio, to increase dissolved oxygen efficiency, simultaneously because the flow velocity of fluid orifice is higher, can draw the water body of greater amount, flow and improve the flow velocity in groove, increase mixing effect.

In addition, can utilize one or more air manifold to utilize venturi-effect, suck the treatment agent (as PAC or clorox etc.) in liquor tank, utilize high velocity flow to accelerate mixing of medicament and water body, increase the contact rate of medicament, improve the utilization ratio of medicament.

Thereby the utility model has embodied the aeration agitation device (as supplier and the medicine machine of the floating micro bubble removing of aeration, medicine system and air) of multi-usage, has reduced the setting of equipment, improves the efficiency of oxygen supply 3～5% of aerating system simultaneously.

Embodiment

Below in conjunction with Fig. 1 to Fig. 4, jet-flow aeration agitator of the present utility model is made and being illustrated.It comprises mixing chamber 1, described mixing chamber 1 front side connects faying flange 2, faying flange 2 connects circulating water line, circulating water line connects recycle pump, recycle pump is placed in aerator tank 5, and mixing chamber 1 rear side connects diffuser tube 3, is provided with a bundle holes oralia 10 in described mixing chamber 1, described bundle holes oralia 10 is provided with a plurality of fluid orifices 101, and described bundle holes oralia 10 front sides are provided with at least one air manifold 4 and air communication.Described air manifold 4 ends connect an air chamber 7, and described air chamber 7 is provided with an air inlet supervisor and is communicated with air amount with atmosphere, and air inlet supervisor oral area is tubaeform so that introducing air.Described bundle holes oralia 10 front sides are also provided with at least one air manifold 4 and are communicated with liquor tank 6, and the liquid in liquor tank 6 enters mixing chamber 1 through air manifold 4.Described diffuser tube 3 is tubaeform, and described diffuser tube 3 middle parts are along being circumferentially evenly equipped with 4～6 pod apertures 30.Described a plurality of fluid orifice 101 evenly arranges a circle or is multi-turn concentric(al) circles around bundle holes oralia 10 centers, and described fluid orifice 101 flares are to form cluster fluidic.

When in recycle pump extraction aerator tank 5, recirculated water flow to bundle holes oralia 10 by circulating water line, current are flowed out and are produced Wen Tuoli tube effect by fluid orifice 101, the aperture that air is flow to fluid orifice 101 through air supervisor, air chamber 7 and air manifold 4 in atmosphere is located, high velocity flow by aperture generation is introduced air in water, and be cut into micro bubble, through mixing chamber 1 to diffuser tube 3, because the flow velocity in diffuser tube 3 is far above aerator tank 5, therefore produce drageffect, water is sucked and increased the recirculated water water yield by pod apertures 30, to reach the effect that improves aeration effect.

While being connected to liquor tank 6 if any air manifold 4, current are flowed out and are produced Wen Tuoli tube effect by fluid orifice 101, the aperture that liquid is flow to fluid orifice 101 through air manifold 4 in liquor tank 6 is located, high velocity flow by aperture generation is added to the water liquid, and the mixing effect causing because of high velocity flow, through mixing chamber 1 to diffuser tube 3, because the flow velocity in diffuser tube 3 is far above aerator tank, therefore producing drageffect sucks water to increase the recirculated water water yield by pod apertures, to reach, improve liquid mixed effect, reduce invalid dispensing.
