Abstract
The utility model relates to a gas-liquid mixing device, in particular to a gas-liquid solution device with high gas solubility, which solves the problems that the absorbing quantity of the gas is limited, the solution period is long, the solubility is not high, the size is big, and the solution efficiency of the mixed gas and liquid is low. The device can achieve saturation solution state quickly, the aspiration is flexible, the size is small, the solution effect is high, which comprises a first pump with a liquid outlet end that is at least connected with one liquid inlet end of a second pump via a connecting pipeline, a gas inlet pipe is communicated at the joint of two pumps.
Description
Technical field
The utility model relates to a kind of Liqiud-gas mixing device, especially relates to a kind of liquid-gas mixture and dissolution instrument with high gas solubility.
Background technology
In the breed or the industry of growing seedlings, be to accelerate breeding, promote growth, often need in water, inject oxygen or ozone.Existing aerating device has two kinds, a kind of is pot type, a kind of is to utilize pump and Venturi tube, in the pot type oxygenate apparatus, top input liquid or water from tank body make liquid down carry in the mode of spray, and oxygen or ozone are from the bottom input of jar, by liquid from top to bottom with gas cross flow one from the bottom up, oxygen or ozone are dissolved in liquid or the water.This dissolution mechanism gas-liquid mixed time is long, and gas dissolves in that the amount of liquid is limited, and solubility is a definite value, and dissolved efficiency is low, and volume is big.Another kind utilizes the Liqiud-gas mixing device of pump and Venturi tube, be in infusion pipeline, to add pump and Venturi tube successively, pump makes the supercharging of input liquid, Venturi tube narrows down the circulation passage of liquid, produce negative pressure, suck gas herein, mix the back is transported to needs by pipeline place with liquid.The soakage of this hybrid mode gas is limited, cause gas be dissolved in the liquid amount seldom.Solubility is not high.In existing liquid-gas mixture and dissolution instrument, air-breathing value is fixed in a word, and dissolution time is long, and the gas-liquid mixed dissolved efficiency is low.
The utility model content
The utility model is limited for existing Liqiud-gas mixing device solves the above-mentioned gas soakage, dissolution time is long, solubility is not high, volume is big, the shortcoming that the gas-liquid mixed dissolved efficiency is low provides a kind of dissolved state that can reach capacity fast, and elasticity is air-breathing, volume is little, the liquid-gas mixture and dissolution instrument that dissolved efficiency is high.
The utility model liquid-gas mixture and dissolution instrument comprises first pump, and wherein the outlet end at described first pump is connected with the liquid feeding end of one second pump at least by connecting line, feeds air inlet pipe in the junction of described two pumps.
The utility model liquid-gas mixture and dissolution instrument, the flow of wherein said first pump is little, and the flow of second pump is big.
The utility model liquid-gas mixture and dissolution instrument, the flow of wherein said first and second pumps is identical, and is provided with intercepter plate at the drain pipe place of described first pump.
The utility model liquid-gas mixture and dissolution instrument, wherein said first and second pumps are centrifugal pump, turbine pump or screw pump.
The beneficial effects of the utility model are: owing to add another pump, the liquids and gases of input can be rotated at a high speed jointly therein, resolve into vaporific, make the abundant mixed dissolution of liquids and gases, become foamed mixture, dissolved state fast reaches capacity, and second pump also can strengthen suction capacity, make the gas soakage not have fixed proportion, this device only needs the pump housing and connecting line, and volume dwindles greatly.
Description of drawings
Fig. 1 is the structural representation of the utility model liquid-gas mixture and dissolution instrument.
The specific embodiment
Fig. 1 is the utility model preferred embodiment, as shown in the figure, liquid-gas mixture and dissolution instrument 1 comprises first pump 2, its outlet end 3 is connected with the liquid feeding end 7 of second pump 6 by flange 4, connecting line 5, in the adpting flange 4 of first pump 2, be provided with intercepter plate 8, on the close connecting line 5 of first pump 2, feed air inlet pipe 9.Wherein first pump 2 is identical with the flow of second pump 6.And two pumps are centrifugal pump.
Its course of work is: the liquid that first pump 2 pumps into, dam by intercepter plate 8 during by outlet end 3, relation according to fluid flow and flow velocity, flow reduces, flow velocity is accelerated, pressure reduces, and therefore produces negative pressure in connecting line 5, sucks gas by air inlet pipe 9, at this moment, gas and mixtures of liquids are imported in second pump 6, under the effect of second pump 6, and the common rotation at a high speed of gas and mixtures of liquids, resolve into vaporific, make the abundant mixed dissolution of gas and liquid, become foamed mixture, dissolved state fast reaches capacity, second pump also can strengthen suction capacity simultaneously, make the gas soakage not have fixed proportion, this device only needs the pump housing and connecting line, and volume dwindles greatly.
Claims (4)
1, a kind of liquid-gas mixture and dissolution instrument comprises first pump, it is characterized in that being connected with the liquid feeding end of one second pump at least by connecting line at the outlet end of described first pump, feeds air inlet pipe in the junction of described two pumps.
2, liquid-gas mixture and dissolution instrument according to claim 1 is characterized in that the flow of described first pump is little, and the flow of second pump is big.
3, liquid-gas mixture and dissolution instrument according to claim 1 is characterized in that the flow of described first and second pumps is identical, and is provided with intercepter plate at the drain pipe place of described first pump.
