Abstract
The utility model relates to a conical surface type jet aerator. The conical surface type jet aerator is characterized by the inclusion of a sandwich type conical bowl shaped jet aerator body composed of an upper diversion cone (2) with a spherical crown shaped top and a lower diversion cone (1) with a spherical crown shaped top and provided with an annular slot with an opening type structure; an air intake hood (5) is arranged above the spherical crown part of the upper diversion cone (2); an air intake pipe orifice (6) connected with an air source is formed at the top of the air intake hood (5); a plurality of air inlet holes communicated with a sandwich cavity of the conical bowl shaped jet aerator body and an inner cavity of the air intake hood (5) are respectively processed at the spherical crown part of the upper diversion cone (2), which is covered by the inner cavity of the air intake hood (5); and a water inlet pipe orifice (8) communicated with the sandwich cavity of the conical bowl shaped jet aerator body is formed at the concave position of the lower diversion cone (1).
Description
Technical field
The utility model relates to and is applicable to a kind of tapered conical surface type jet aerator of jet face that increases dissolved oxygen in sewage disposal.
Background technology
The jet aerator of prior art is single hose or the multitube formula of arranging.Single hose is made up of a jet pipe.The multitube formula of arranging is combined by several jet pipes, but alinement shape, annular.Its jet orifice of various forms of jet aerators is point type.
Above-mentioned existing structure mainly has the following disadvantages:
When the jet pipe horizontal-jet of jet aerator, jet pipe top and front upper place be aeration fully.Arrange ringwise and when spray oblique below, though improved the shortcoming that level is arranged, also have only the injection of several points in the plane when the jet pipe of jet aerator, the part aeration between the jet orifice is still inhomogeneous.Therefore existing jet aerator all can not reach the aeration effect of uniform.Existing jet pipe inlet mouth is relatively large, causes the bubble that ejects bigger, and gas-water contact area is little.
Summary of the invention
A kind of structure that the purpose of this utility model provides at existing weak point in the above-mentioned prior art just is relatively reasonable, the conical surface type jet aerator that is applicable to increase dissolved oxygen in the sewage disposal of low processing cost.
The purpose of this utility model can realize by following technique measures:
Conical surface type jet aerator of the present utility model comprise by the top be domed on, the ring edge that following deflection cone is formed is the sandwich-type awl bowl-type ejector main body of open type structure (annulus), be provided with intake hood above the spherical crown of the deflection cone part on described, be provided with the air inlet mouth of pipe that is connected with source of the gas at the top of intake hood, the intake hood inner chamber covered on the spherical crown of deflection cone partly be processed with the air inlet port that several are communicated with awl bowl-type ejector main body interlayer chambeies and intake hood inner chamber, be provided with in the recessed heart position of deflection cone down and be communicated with the water inlet pipe mouth of boring bowl-type ejector main body interlayer chamber; Described interlayer chamber is used to make the gas that is entered by top to carry out sufficient air water with the liquid that is entered by the bottom in the interlayer chamber and mixes, and sprays from the annulus of interlayer chamber ring edge.
Combine by uniform former and bolt between the upper and lower deflection cone described in the utility model, former plays accurate localized effect, can guarantee the distance of deflection cone up and down;
Principle of work of the present utility model is as follows:
Superposed intake hood available buffer air inlet in the utility model, the spherical end socket of different sizes is established on the top of deflection cone up and down, and current are smoothly passed through; The spherical end socket on last deflection cone top can make current enter the mixing of interlayer chamber uniformly, and reduces resistance; After air water enters the mixing of interlayer chamber simultaneously, from the annulus of bottom, interlayer chamber, spray, the air-water mixture of ejection is the conical surface.
The beneficial effects of the utility model are as follows:
Because jet face of the present utility model is tapered, so aeration is even, aeration area is big; Inlet mouth is that a plurality of apertures are formed, and the bubble when mixing on the conical surface is diminished, and can increase gas-water contact, to increase the dissolved oxygen in the water.

Each sequence number and title among the figure are respectively: 1, following deflection cone, 2, go up deflection cone, 3, bolt, 4, nut, 5, intake hood, 6, the air inlet mouth of pipe, 7, former, 8, water inlet pipe mouth, 9, the pond, 10, admission passage, 11, jet aerator, 12, suction culvert.
Embodiment
The utility model is further described below with reference to embodiment (accompanying drawing), but does not limit the utility model.
As Fig. 1, shown in Figure 2, conical surface type jet aerator of the present utility model comprise by the top be domed on, following deflection cone (2,1) the ring edge of Zu Chenging is the sandwich-type awl bowl-type ejector main body of open type structure (annulus), be provided with intake hood (5) above the spherical crown of the deflection cone part on described, be provided with the air inlet mouth of pipe (6) that is connected with source of the gas at the top of intake hood, spherical crown at intake hood (5) the last deflection cone that inner chamber covered partly is processed with the air inlet port that several are communicated with awl bowl-type ejector main body interlayer chamber and intake hood inner chamber, is provided with the water inlet pipe mouth (8) that is communicated with awl bowl-type ejector main body interlayer chamber in the recessed heart position of following deflection cone; Described interlayer chamber is used to make the gas that is entered by top to carry out sufficient air water with the liquid that is entered by the bottom in the interlayer chamber and mixes, and sprays from the annulus of interlayer chamber ring edge.
Combine by uniform former (7) and bolt (3), nut (4) between the upper and lower deflection cone described in the utility model.
As shown in Figure 3, the utility model is as being applicable to that the device that increases dissolved oxygen in the sewage disposal is installed on the bottom of pond (9), and the jet orifice plane parallel is at the bottom of the pond.During this device work, air water is simultaneously with the certain pressure access to plant, gas enters intake hood (5) by admission passage (10), the air inlet mouth of pipe (6), after gas cushions in intake hood, the air inlet aperture a plurality of arranged in a uniform that is provided with by last deflection cone (2) enters the mixing of taper interlayer chamber again, water enters between the taper interlayer chamber by suction culvert (12), water inlet pipe mouth (8), air water (taper interlayer chamber) in the gap of two deflection cones sprays from the annulus of bottom, interlayer chamber after finishing and mixing, and the air-water mixture of ejection is the conical surface.
