Description

Gas-liquid mixing pump

The utility model relates to a kind of pump, is kind of a gas-liquid mixing pump specifically.

Gas-liquid mixing pump commonly used now mainly includes a pump housing, and this pump housing is provided with liquid inlet, gas access and outlet, is provided with an impeller by the motor shaft drive in the pump, and this impeller is provided with blade, and this blade is generally centrifugal.The working principle of this pump be in gas and the liquid input pump housing after, when the rotation of impeller, blade outwards throws away under action of centrifugal force, constantly push liquids and gases to outlet end, the impeller of this pump adopts the eccentric structure in addition, the flowing space of liquids and gases is constantly dwindled, constantly increase the pressure of liquid in the pump thus.And facts have proved of using, the gas of the gas-liquid mixing pump of this kind structure and liquid are to be the mode that line moves along circumference to be pushed forward at the pump housing, so its gas-liquid mixed rate is not high, generally the highlyest only can reach 25%～35%.

The purpose of this utility model is to provide a kind of gas-liquid mixing pump, and shape is mobile in the shape of a spiral to make the interior current of pump, and constantly increases the pressure in the pump, to improve the gas-liquid mixed rate in the pump housing.

The purpose of this utility model is achieved in that a kind of gas-liquid mixing pump, include a pump body and a pump cover, the pump body be provided with gas access, liquid inlet with and outlet, be installed with impeller on the one motor input shaft, this impeller is located in the pump housing and by driven by motor and is rotated, the periphery that it is characterized in that described impeller is that the boundary is provided with " people " font arc limit with the axial centre, it is thicker that impeller is central part, the outermost periphery is feathered shape, has on the periphery on the shape arc limit of " people " to be evenly distributed with radial blade.

The purpose of this utility model also can realize by following measure, and described liquid inlet is and is horizontally disposed with, and the gas access is perpendicular to the liquid inlet, and is located on the passage of liquid inlet; The height of impeller upper blade and impeller week, rim was identical, combined with the arc limit of ' people ' font of impeller, made the arc groove that is formed with two symmetries between per two blades; Be provided with seal arrangement between the described motor shaft and the pump housing, the sealing device can be mechanical sealing.

Working principle of the present utility model and effect be, it is roughly by six critical piece assemblies, the pump housing and pump cover, and it is provided with a seal arrangement between the two, can keep the pressure that produces in the pump; The motor shaft that runs through the pump housing, the torque of transmitting motor, impeller is rotated because the impeller periphery has radial blade, when impeller turns round in the pump housing, produce and liquid between frictional force F, this frictional force F along the revolution ten thousand of liquid with force feed liquid; Meanwhile, liquid produces centrifugal force C along " people " font arc groove of impeller periphery, and this centrifugal force C and gyratory directions form and intersect the power of carrying liquid, its as a result liquid in the pump housing, form water vortex and flow, and constantly pressurize.Under this kind condition, gas and liquid have reached the mixing of filling part in the pump, and evidence gas-liquid mixed rate of the present utility model can reach more than 85%.When the utility model should be in water treatment, input liquid can be through preliminary treatment sewage, gas access input ozone, water is reaching composite rate 85% when above with ozone, and along with the increase of pump internal pressure, other material and ozone in the water react, promptly to reach the effect of water body purification, adjust the oxygen content in the gas in addition, can directly generate water and combine oxygen-enriched water fully with oxygen, people are oxygen intake in drinking-water.

The explanation of accompanying drawing drawing:

Fig. 1 three-dimensional exploded view of the present utility model;

Fig. 2 sectional view of the present utility model;

Fig. 3 fundamental diagram of the present utility model.

It is as follows to describe the utility model in detail below in conjunction with embodiment and accompanying drawing thereof;

See also shown in Fig. 1 and 2, the utility model includes a pump body 102, pump cover 103 has seal arrangement 123 between the pump housing 102 and pump cover 103, can keep the pressure in the pump thus.This pump housing 102 is provided with liquid inlet 1021, gas access 1022 and liquid outlet 1023.The liquid inlet is 1021 and is horizontally disposed with, and gas access 1022 is perpendicular to liquid inlet 1021, and is located on the passage of liquid inlet 1021.

One motor shaft 108, this motor shaft is through the pump housing 102, be provided with mechanical sealing device 105 between the motor shaft 108 and the pump housing, this mechanical sealing device 105 is fixed in the inwall of the pump housing 102 by a back-up ring 104, and this back-up ring 104 can be used as the axially locating of motor shaft 108.Motor shaft 108 is via a key 116 transmissions one impeller 107.

The periphery of the impeller 107 of maximum characteristics of the present utility model on being serves as that the boundary both sides have an arc limit 1071 that is " people " font with its axial centre, and be provided with the blade 1072 of radial distribution at this peripheral region, the height of impeller 107 upper blades 1072 is identical with impeller 107 all rims, combine with the arc limit 1071 of ' people ' font of impeller 107, make 1072 arc grooves that are formed with two symmetries of per two blades.

The pump housing 102 is provided with to projecting inward protruding evil idea 1021, pump cover 103 also is provided with inside bulge loop 1031, two bulge loop clamps make the pump housing 102 inner peripherys be formed with a cavity 1024 in the thicker wheel board of impeller 107, the liquids and gases mixed flow in this cavity 1024 in the front pump.

Working principle of the present utility model is, liquids and gases are entered in the pump housing 102 of sealing by inlet, when impeller 107 drives revolution by motor shaft 108 in the pump housing 102, this blade 1072 produce and liquid between frictional force F, this frictional force F is along the gyratory directions force feed liquid of liquid; Meanwhile, liquid produces centrifugal force C along " people " font arc groove 1071 of impeller 107 peripheries, this centrifugal force C and gyratory directions form and intersect the power of carrying liquid, its as a result liquids and gases in the cavity 104 of the pump housing 102 inner peripherys, form water vortex and flow, and constantly pressurize.Under this kind condition, gas and liquid have reached the mixing of filling part in the pump, and evidence gas-liquid mixed rate of the present utility model can reach more than 85%.
