Description

Self-suction gas-liquid mixing pump and gas-liquid mixed method
Technical field: the present invention relates to a kind of gas-liquid mixing pump, being mainly used in one is air-floating processing apparatus, ozone self-suction gas-liquid mixing pump oxygen water generator, oxygen-enriched water producing equipment, biochemical processing device etc.; The 2nd, the heating agent of all temps controlling device, refrigerant circulation are carried; The 3rd, transfer low-viscosity (mobile) liquids such as gasoline, dilution, all kinds of solvents from sunken tank attraction or high pressure; The 4th, the spraying of clear water, pure water, food, chemical liquids, waste liquid etc. is handled; The 5th, severe this purposes of intermittent working, water hammer, back pressure rapid change and so on; The 6th, adopt sampling water from rivers and creeks or water storage tank etc., transfer foamable liquid, be easy to occur the liquor charging the long transverse tube road of air pocket.
Background technique: existing gas-liquid mixing pump, on structural design, gas-liquid in the pump housing is entered the hole directly for the inlet hole and the inlet opening of the pump housing, and a plurality of blades in the impeller for be staggered, blade and interlobate wheel face be planar structure, its insurmountable difficult problem is: enter the gas-liquid mixed weak effect in the pump housing, do not reach designing requirement.
Summary of the invention: purpose of design of the present invention is exactly to solve the technical barrier that exists in the background technique, makes the gas and the liquid that enter in the pump housing be issued to abundant mixing to greatest extent, and its mixed effect reaches and surpasses designing requirement, to satisfy requirement of client.In order to reach this purpose of design, in the pump housing design, designed air absorbing mouth, this air absorbing mouth is contained in the suction port of the pump housing, and be arranged circumferentially one section Gas-Liquid Dispersion composite beam in the pump housing gas-liquid import below the relief opening of this air absorbing mouth, make the gas that will enter in the pump housing and liquid when entering the import of pump housing gas-liquid, the hoop Gas-Liquid Dispersion composite beam that at first is set in the gas-liquid import disperses, mixes, reach the secondary Forced Mixing of gas, liquid, and can eliminate the gross blowhole in the gas-liquid mixed effectively.Secondly, in the design of impeller, become semi-open type that tooth is milled impeller impeller design, i.e. the tapered structure of a plurality of interlobate wheel faces in the impeller wheel face has the sheet (seeing accompanying drawing 5) of inverted v-shaped below the face of blade is.The semi-open type that is positioned at the pump housing is milled impeller to gear and is matched with the inner chamber of the pump housing, make enter on the impeller blade and the taper wheel face on gas-liquid under the effect of quick runner, make the gas-liquid that acts on the pump housing inwall get back on the impeller again in effect following moment of reaction force, the impeller of high speed rotating acts on it inwall of the pump housing again once more, so ring repeatedly follows, and gas, liquid are constantly discharged by the water outlet of the pump housing under through pressure, well-mixed condition.Its technological scheme: 1. self-suction gas-liquid mixing pump, it comprises motor (2), the pump housing (3), mechanical seal (4), impeller (5) and pump cover (6), the pump housing gas-liquid import hoop that is positioned at air absorbing mouth (1) relief opening below is equipped with Gas-Liquid Dispersion composite beam (10); The tapered structure of wheel face (12) in impeller (5) wheel face between a plurality of blades (11).Air absorbing mouth (1) is housed in the valve screw.Sylphon seal is adopted in mechanical seal (4).2. the mixed method of self-suction gas-liquid mixing pump, enter the interior water of the pump housing when entering the import of pump housing gas-liquid, after being arranged circumferentially Gas-Liquid Dispersion beam in the gas-liquid import and force to disperse mixing, the negative pressure that impeller high speed spinning roller is produced gas is sucked in the pump chamber by the air absorbing mouth on the pump housing and with pump chamber in liquid Forced Mixing under the double action of impeller and pump chamber inwall.Working principle: air-breathing, the water sucking mouth of gas-liquid mixing pump utilizes negative pressure to suck gas, therefore need not air compressor and atmosphere sparger: mix, the design of Gas-Liquid Dispersion composite beam and Gas-Liquid Dispersion mixing impeller in the pump housing, liquid has been reached fully in dynamically with gas mix, and need not stirrer and mixer; Dissolving, because the pressurization in the pump mixes, gas and liquid can fully dissolve, its solubility can reach 95~100%, need not pressure air-dissolving jar or reaction tower and can produce the high concentration lysate.A gas-liquid mixing pump can carry out also directly the high concentration lysate being delivered to the use point behind gas-liquid attraction, the mixed dissolution.Adopt the technical program institute development product, the one, the interior pressurization of, pump air-breathing while absorbing water mixes, mixed micro air bubble is 20~30 μ, and the gas-liquid solute effect good, compare with background technique, its gas-liquid dissolved efficiency multiplication, the gas-liquid dissolution rate reaches 95~100%, solves background technique and wants to solve and insurmountable technical barrier; The 2nd, stable performance, efficient height, noise are low; The 3rd, omit air compressor, various mixer, high pressure dissolving and releaser etc.; The 4th, produce Ozone Water with this pump, can save various mixers, large-scale oxidation tower etc.; The 5th, have good self-priming performance, applied range, simple to operate.
