The layering aeration machine can obviously improve water bottom dissolved oxygen and increase temperature, increase the activity of the microorganism at the water bottom, and accelerate self cleaning capacity of the water bottom.

Description

Separate the laminar aerator

[technical field]

The utility model relates to a kind of aerator that is used in the water treatment field, more particularly, it is a kind of laminar aerator of separating, can collect surface water, collection top layer dissolved oxygen over-saturation that can be a large amount of, the higher relatively water body of temperature are transferred to the bottom of water body with it, improve and improve water bottom dissolved oxygen and temperature, increase the water bottom microbic activity, quicken the self-purification capacity of water bottom.

[background technology]

Traditional water body oxygenation notion all is by inject air or pure oxygen in water body, make oxygen contact and be transferred in the water body with water body, realize the purpose of oxygenation, in the actual nature a kind of phenomenon being arranged is exactly that the water body top layer all contacts with atmosphere, surface water is in state of saturation always, especially at high temperature season, the algae of water surface carries out strong photosynthesis and discharges a large amount of oxygen and make the water body surface water be in the over-saturation state, form the water body of eutrophication, and the dissolved oxygen that in time is not diffused into the bottom directly overflows the water surface, is diffused in the atmosphere to go.

In the past for the water body of eutrophication, general all improve dissolved oxygen in the water body by traditional mechanical aeration oxygenation way or blast aeration oxygenation way, make the organism in the aerobic microbiological decomposition digestion water in the water body, thus the excessive multiplication of algae in the control water body.

Yet existing traditional aerator generally all designs at sewage disposal, special emphasis is to improve oxygen in water, satisfy the demand of good sample microorganism in the water body, in addition sewage disposal be a high concentration microorganism with water body in pollutent fully contact the blended process, and the water body high concentration microorganism on the eutrophication mainly concentrates on the bottom of water body, conventional aerator complex structure, energy consumption height, drop into high, inconvenient, DeGrain are installed, and can not adapt to the influence of change of level.

[summary of the invention]

In order to solve deficiency of the prior art, the utility model provides a kind of laminar aerator of separating, can collect surface water, collection top layer dissolved oxygen over-saturation that can be a large amount of, the higher relatively water body of temperature, it is transferred to the bottom of water body, improve and improve water bottom dissolved oxygen and temperature, increase the water bottom microbic activity, quicken the self-purification capacity of water bottom.

The purpose of this utility model realizes by the following technical solutions:

Separate the laminar aerator, constitute by special-purpose floating drum, aeration power plant module, Water collecting tube, guide shell, rectified diffusion device, waterproof junction box, each parts is linked to be an organic whole by web member, the aeration power plant module is arranged in the Water collecting tube, the Water collecting tube below is connected with guide shell, the guide shell below is connected with the rectified diffusion device, and waterproof junction box is installed on special-purpose floating drum top, and special-purpose floating drum floats on water surface.

Described special-purpose floating drum floats on the water surface whole aerator, is not subjected to the influence of change of level and stormy waves, but non-stop run.

Described aeration power plant module, form by following any structure but be not limited thereto structure, the circulation submersible pump provides power or the direct-connected aeration impeller of submersible machine or sun-generated electric power drives impeller or wind drive aeration impeller, it is positioned at Water collecting tube, and the rotary thrust by its generation is advanced into guide shell and rectified diffusion device with the water in the Water collecting tube.

Described Water collecting tube, it is provided with a plurality of surface waters and collects mouth, the water that epidermis can be rich in dissolved oxygen is directly collected, and directly inject in the oxygen-starved area of water bottom by aeration driver module wherein, the water body of oxygen-starved area moves up owing to being squeezed, realize oxygenation thus and make two kinds of effects of stream, break the phenomenon of water body natural layering, realize that water body separates layer.

Described guide shell and rectified diffusion device, water in the Water collecting tube is transferred to bottom hypolimnion low temperature low dissolved axygen district, and diffusion rapidly, thereby reach purpose to water body oxygenation, simultaneously in bottom low temperature and the more weak zone of light, algal grown is suppressed, thereby also has the effect of certain control algae.

The utility model is the problem that overcomes power supply difficulties such as large-size lake reservoir, and the aeration module that can provide a kind of sun power or wind energy to drive makes machine non-stop run under unattended state, realizes the energy-conserving and environment-protective of equipment.
