To the deficiency that prior art exists, the utility model purpose provides a kind of easy for installation, energy consumption is low, oxygen-transfer efficiency is high, cost is low shallow water type up-flow circulation reoxygenation device, need not the disturbance bed mud.

To achieve these goals, the utility model is to realize through following technical scheme:

The utility model comprises and is fixed on water-bed base, is arranged on and rises tube on the center on the base, be installed in and rise tube opening part and the contacted release head of the water surface on the center and be fixed on the pipe fitting that rises the tube outside on the center and all seal up and down; The zone that rises between tube and the pipe fitting on the center forms collection chamber and reoxygenation chamber from top to bottom successively, and the indoor aeration tube that is provided with of said reoxygenation is provided with a prosopyle at least in the outside of reoxygenation chamber; Be positioned to rise on the tube on the center at collection chamber place and be provided with a production well at least, be positioned to rise on the tube on the center at place, reoxygenation chamber and be provided with a posticum at least.

Be equipped with in the above-mentioned collection chamber and the corresponding sleeve flap of production well overflow weir, be used for buffer gas flow.

What above-mentioned aeration tube adopted is micropore aeration pipe.

Above-mentioned micropore aeration pipe is installed in the bottom of reoxygenation chamber.

Above-mentioned release head be shaped as taper shape.

The utlity model has that energy consumption is low, the oxygen velocity of diffusion is fast, the reoxygenation ability by force, is not stirred bed mud, realize utilizing air oxygenation and oxygenation simultaneously after residual air promote water body circulation diffusion; Increase substantially the characteristics of oxygenation service area area; Advantages such as equipment is simple, easy for installation are the fast emergent oxygen replenishing equipment of the black foul sewage of outbursts such as a kind of ideal shallow water Hu Ku, pond, river course when dying.

Description of drawings

Fig. 1 is the structural representation of the utility model.

Each label among the figure: base 1 rises tube 2, release head 3, pipe fitting 4, collection chamber 5, reoxygenation chamber 6, micropore aeration pipe 7, prosopyle 8, production well 9, posticum 10, inner core 11-1, urceolus 11-2, flange 12 on the center.

Embodiment

For technique means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with embodiment, further set forth the utility model.

Referring to Fig. 1, the utility model comprises liter tube 2 on the base 1 that is fixed on the subaqueous concrete basis (not drawing among the figure), the adjustable for height center, is installed in the release head 3 that rises tube 2 top end opening places on the center and is fixed on the pipe fitting 4 that rises 2 outer lower portion on the center through flange 12.

Wherein, the bottom that rises tube 2 on the center is sealed and is fixed on the base 1; Release head 3 contacts with the water surface; The upper and lower end of pipe fitting 4 all seals.

The zone that rises on the center between tube 2 and the pipe fitting 4 forms collection chamber 5 and reoxygenation chamber 6 from top to bottom successively, is provided with aeration tube in the reoxygenation chamber 6, is provided with a prosopyle 8 at least in the outside of reoxygenation chamber 6.

Rise on the tube 2 on the inner center of collection chamber 5 and be provided with a production well 9 at least, rise on the tube 2 on the inner center, reoxygenation chamber 6 and be provided with a posticum 10 at least.

Be equipped with in the collection chamber 5 and production well 9 corresponding sleeve flap overflow weirs, its effect is: earlier as water seal arrangement, and the release gas circuit of turning back after descending because of gas gathers as water level then behind the gas overflow.
