Abstract

The utility model relates to an air and water emulsifying type enhanced oxygen richening device, which belongs to the oxygen richening machine for aquaculture. The utility model comprises a stirring type oxygen richening machine and a plurality of pontoons, wherein the stirring type oxygen aerator is composed of impellers driven by an electromotor, and the pontoons are fixedly connected with the electromotor through supporting rods and are used for bearing the electromotor out of a water surface; an inflation pump is arranged on an outer shell of the electromotor; an air ejecting pipe on which a plurality of air ejecting holes are opened is arranged under the impellers; the outlet of the inflation pump is communicated with the air ejecting pipe through an air guiding pipe. The utility model can pressurize the air; uncountable tiny air bubbles are ejected into water through the air ejecting pipe and are stirred and pulverized by the impellers in a high speed; the utility model has effects of oxygen richening in the high speed for meeting requirements of the aquaculture in high density.

Description

The powerful oxygen-increasing device of air water emulsifying-type

The utility model relates to the mechanism manufacturing field that culture fishery used mechanism, especially culture fishery are used for oxygenation.

Now in the culture fishery, the general mechanical agitation type oxygenating machine of Shi Yonging, mainly by motor, and mixing component compositions such as (vane type or propeller formula are generally arranged), a plurality of keg floats (2～6 are not waited) connect firmly through support bar mutually with motor, so that motor emerges motor direct-drive impeller or propeller.It forms the countless globules by the mechanical agitation water body, the contact area of increase and air, thus increase the water body dissolved oxygen amount.But along with culture fishery such as fisheries development, the cultured output of unit surface improves constantly, and above-mentioned mechanical agitation type oxygenating machine oxygenation effect is relatively poor, is difficult to satisfy the needs that the high-density shoal of fish is cultured.

The purpose of this utility model is to overcome above-mentioned weak point and provides a kind of air water emulsifying-type powerful oxygen-increasing device, and it is changed a social system on above-mentioned mechanical agitation type oxygenating machine basis, and has better oxygenation effect.

The purpose of this utility model is realized by the following technical programs: the powerful oxygen-increasing device of a kind of air water emulsifying-type, comprise the stirring-type oxygenating machine that constitutes by the electric motor driving impeller and connect firmly and be used to hold up a plurality of keg floats that above-mentioned oxygenating machine emerges its motor through support bar and motor, it is characterized in that, being provided with an inflation at the position that motor emerges adopts, the lower position of described impeller is provided with gas ejector pipe, have a plurality of gas orifices on the gas ejector pipe, the inflation pump outlet is connected with gas ejector pipe through airway.

According to above technical scheme, on the basis of existing machinery stirring-type oxygenating machine, newly-increased inflation mechanism, the aerator pump forced gas supply is delivered to air the below that has oxygen increasing machine impeller now, gas orifice on gas ejector pipe erupts and goes out, air forms countless micro-bubbles in water, these micro-bubbles are slowly floating to rising less than water because of proportion, on the one hand, in slowly rising floating process, part oxygen is dissolved in the water, reach oxygenation effect; On the other hand, by the high speed rotating stirring of impeller, be fused into emulsified state with the powerful pulverizing of these microbubbles and with the water body brute force, make oxygen further dissolve in the water, form the oxygen enrichment water body,, reach high speed oxygenation purpose after stirring is bulk diffusion to whole water body with above-mentioned heavy-oxygen-enriched water.

Below in conjunction with accompanying drawing the utility model is described in detail.

Fig. 1 is the utility model schematic perspective view;

Fig. 2 is the vertical view of gas ejector pipe shown in Figure 1;

Fig. 3 is the vertical view of the another kind of embodiment of gas ejector pipe shown in Figure 1.

Fig. 1 illustrates, on the axle of motor 2 impeller 4 (perhaps adopting propeller) is installed, motor 2 tops are covered with rain-proof cover 1, keg float 6,6a, 6b connect firmly with motor 2 shells mutually by

support bar

5,5a, 5b respectively, so that motor 2 emerges (not limitting for the number 2-6 of keg float), the position that motor 2 emerges is provided with an aerator pump 3 (conventional air compressor pump), gas ejector pipe 8 is arranged on the lower position of impeller 4, spacing 10～50cm, gas ejector pipe 8 adopts metallic substance or rigid plastics to make bore 10-40mm; Have gas orifice 9 (referring to Fig. 2, Fig. 3) on the gas ejector pipe 8 and adopt laser boring or machine drilling or once shaped drilling, the aperture is less than 1mm, and hole density is 1～20/cm ²The aperture is more little, and then density can be big slightly; The aperture is big slightly, and then density is slightly little.The shape of gas ejector pipe 8 can be annular or Y-shaped shown in Figure 3 shown in Figure 2.Gas ejector pipe 8 is the 10-50cm place below impeller 4, is to be horizontally disposed with.Among Fig. 1, the outlet of aerator pump 3 is communicated with support bar 5,5a, the 5b of three double as airways, and airway 7,7a, the 7b through vertically being provided with is communicated with gas ejector pipe 8 respectively again.Airway 7,7a, 7b and

support bar

5,5a, 5b all adopt metallic substance or rigid plastics to make.
