Description
Technical field
The present invention relates to technical field of fishery machinery, be specifically related to a kind of aquatic products pond oxygen system.
Background technology
Aquaculture is the production activity breeding, cultivate and gathering in the crops aquatic animals and plants under manual control, the product of Aquatic product includes fish, shrimp, Eriocheir sinensis, shellfish and various plants etc., in aquatic farm, especially in the case of high-density breeding, the aeration system in pond is essential.
Dissolved oxygen level in pond is low, can cause following problem: 1. aquatile can not get enough oxygen, becomes poor growth, vigor poor；2. water plant grows slowly, and the ability of the water body environment of its purifying water body and construction solid is restricted so that water body is not suitable for aquatic organism growth；3., in anaerobic environment, the Excreta of microbial decomposition aquatic organism and toxin less able, water body environment progressively deteriorates, and affects growth and the quality of Aquatic product product；Above 3 points, all can have a strong impact on the economic benefit of aquaculture.
Application publication number is that the Chinese invention patent of CN 104542424 A discloses a kind of aquaculture pond oxygen-increasing device, including a plurality of oxygen increasing tube, it is provided with steam vent on described oxygen increasing tube, efficiency of oxygen supply is improved by the quantity increasing steam vent, this type of oxygen-increasing device is unsuitable for large-area pond, oxygen is discharged along oxygen increasing tube, it is difficult to accomplish uniform oxygen supply.
Summary of the invention
The purpose of the present invention, is to solve the problems referred to above, it is provided that a kind of aquatic products pond oxygen system.
The technical scheme that the present invention solves the problems referred to above is as follows:
A kind of aquatic products pond oxygen system, plays transmission and the transport frame of framework effect including providing the source of the gas portion of air to be connected with described source of the gas portion and described air is supplied to the oxygen supply portion in pond；Described source of the gas portion includes air compressor machine and the vacuum tank being sequentially connected, and described vacuum tank is provided with barometer, is provided with the first electromagnetic valve, is provided with the second electromagnetic valve between described vacuum tank and described transport frame between described air compressor machine and described vacuum tank；Described transport frame is made up of pipeline, connects described source of the gas portion and part is distributed in described pond；Described oxygen supply portion includes some oxygen supply heads being rotatably coupled to described transport frame, described oxygen supply head is propeller arrangement, including oar axle and the some blades being arranged on described oar shaft end head, described oar axle and described blade are internally provided with the continuous space connected with described transport frame；Described blade includes blade face and blade back two sides, when described oxygen supply head rotates, the one side promoting water body flow is blade face, the opposite face on described blade face is blade back, oxygen supply window it is provided with on described blade back, it is provided with the porous watertight layer that hydrophobic material is made on described oxygen supply window, described porous watertight layer is provided with the supporting layer providing intensity.
Oxygen is increased to certain pressure with described source of the gas portion by oxygen system of the present invention, again by described transport frame by oxygen transmission to described oxygen supply head, oxygen oxygen supply window at described blade blade back is discharged, the oxygen supply head promoting propeller arrangement rotates, and drives water body flow by blade while oxygen supply.
As the saying goes: " Running water never becomes putrid ", the water body of flowing brings fresh nutrient, and it is dispersed in pond easily pile up the dead angle of debirs and toxin, promote the breeding of aquatic plants growth and microorganism, can effectively decompose organic human waste and noxious substance so that water body keeps water quality pure and fresh, and can make full use of the oxygen discharged in described oxygen supply window, make it farthest be dissolved in water body, increase the dissolved oxygen amount in pond.
And owing to debirs and toxin are deposited at the bottom of pond more, oxygen is sprayed downwards by described blade back, coordinate the flowing of water body so that oxygen can more arrive pond bottom, contributes to the decomposition of debirs and toxin.
Oxygen ejects with the form of superfine minute bubbles from described porous watertight layer, coordinate the injection direction that blade back is downward, and the stirring flowing of water body, minute bubbles are more easy to be dispersed to pond everywhere along with injection direction and water body flow, superfine minute bubbles its contact area with water body for larger bubble is bigger, and dissolved oxygen is more abundant more rapidly.
Preferred as technique scheme, described oxygen supply head is connected with described transport frame by water-sealed bearing.
Water-sealed bearing is as prior art, it is adaptable in environment of the present invention.

The gas transmission volume of described transport frame should not be too big, and the most described source of the gas portion expellant gas pressure can decline rapidly, affects efficiency of oxygen supply and effect；Therefore control the volume of gas transmission by controlling the internal diameter of rustless steel pipeline, rustless steel is corrosion-resistant, crushing resistance good, it is adaptable to do the pipeline of transport frame.
Preferred as technique scheme, the bottom being arranged on described pond at described oxygen supply head interval.
Preferred as technique scheme, described porous watertight layer is made up of polytetrafluoroethylene fibre.
Polytetrafluoroethylplastic plastic corrosion resistance is strong, can make hydrophobic material, and material character is stable, it is adaptable to make porous watertight layer of the present invention.
Preferred as technique scheme, the porosity of described porous watertight layer is more than 30%, and the average pore size on described porous watertight layer surface is 10-100 micron.
Porous watertight layer is in addition to scattered ejection air-flow, additionally it is possible to utilize the hydrophobic property on its surface and the intensity of supporting layer offer to place moisture and enter in oxygen supply head.
Preferred as technique scheme, described blade back is directed downward so that the gas of described oxygen supply window injection downwards and surrounding diffusion, drives described oxygen supply head to rotate simultaneously.
Preferred as technique scheme, described supporting layer is to be arranged on the rustless steel orifice plate on described oxygen supply window or the porous plate of stainless steel fibre sintering.
Preferred as technique scheme, described supporting layer is positioned at described porous watertight layer in the one side of described continuous space.
Preferred as technique scheme, described transport frame is helically wire distribution, being arranged on described transport frame of described oxygen supply head interval in described pond.
In sum, the method have the advantages that
A kind of aquatic products pond of the present invention oxygen system can be in conjunction with air-flow dispersion and injection direction and water body stirring flowing, enhance the dissolved oxygen efficiency in pond and speed, enhance microorganism and water plant decomposes debirs and the ability of toxin, both ensure that aquatic organism obtained the oxygen supply of abundance, grows fine, maintain again the water cleaning of water body, growth for aquatic products provides a good environment, and the economic benefit of aquaculture is greatly improved.
