Abstract

The utility model relates to an oxygen increasing pump which is composed of a pump wheel, a pump cover, a pump shaft, a pump pipe, a pump base, a motor, etc. and has the oxygen increasing mechanism that when air is blown in a water body by the atwirl pump wheel, owing to centrifugal and inertial effects, the air can obtain enough kinetic energy and potential energy from an outlet f of the pump wheel and is radiated and diffused towards circumference in a direction which is perpendicular to the pump shaft; longitudinal gyrate stirring and mixing effects between the air and the water body are produced simultaneously to cause dissolved oxygen in the water body to be increased rapidly. The utility model is not only applicable for oxygen increasing of the water body in the environmental protection governance of aquiculture, waste water and sewage water but also can replace a stirring machine or a mixer to stir and mix various types of liquid.

Description

Oxygen increasing pump

The utility model belongs to the mechanical device with water fast oxygenation.

When in the environment protection treating of aquaculture and wastewater and sewage, needing water body oxygenation with the vital movement of keeping organism or the breeding of quickening aerophile bacterium in the water body, need by power in various aerator devices with organic substance digestion, oxidation and decomposition.Common various aerators often have following existing problems at present:

When 1, paddle aerator is worked, only surface water is stirred, make airborne oxygen dissolve in its place water body naturally, dissolved oxygen speed is slow, and water bottom is difficult to implement direct oxygenation;

2, with fan blower or air compressor machine to the water bottom injecting compressed air, because of atmospheric density is very little, be air bubble-shaped after, overflow very soon again from water body;

3, water-spraying oxygen-increasing machine is sprayed onto water and makes it to be dispersed into water droplet in the air and contact the back with air and freely fall and since water droplet aloft the time of staying short and have surface tension, the air (dissolved oxygen) that enters water body is still few.

The purpose of this utility model provides a kind of shortcoming that overcomes above-mentioned various aerators, make air when entering water body, be divided into the multiply air-flow and can obtain enough energy and go deep into water body then, and produce to stir and immixture, thereby the frame for movement design that the water body dissolved oxygen is increased fast with water body.

The purpose of this utility model realizes by this mechanical device of oxygen increasing pump.Below in conjunction with accompanying drawing structure described in the utility model is specifically described.

Accompanying drawing is the structural representation of oxygen increasing pump.Among the figure: 1 is pump impeller; 2 is pump cover; 3 is pump shaft; 4 is pump line; 5 is pump seat; 6 is bearing; 7 is nut; 8 is shaft coupling; 9 is support; 10 is motor.

Pump impeller (1) inner chamber and the upside that are fixed in pump shaft (3) end constitute sprue and secondary channels with backward bent vane.Pump impeller is exposed in the water body, when it makes high speed rotating by the pump shaft drive, because centrifugal and effect of inertia, air at its outlet f place obtained enough kinetic energy and potential energy and with perpendicular to the direction of pump shaft to radiation and diffusion all around, and constantly replenished at the upper and lower sides water body of f, just replenish into again and taken away by the air flow that comes out from the pump impeller sprue, form be vertically gyrate between air and the water body and entrainment, stirring and mixed process, the dissolved oxygen in the water body is increased sharply.Runner is divided into the multiply air-flow with air, increases the contact area between air and the water body.The above space of pump impeller inlet c is negative pressure state, and air enters pump line (4) from interface a inner chamber is the aperture b of circumference uniform distribution, the c that enters the mouth through pump cover (2), is pumped in the water body by sprue.The effect of secondary channels be both can stop water body from pump cover end face and pump impeller shaft in gap d is infiltrated the pump housing, also the portion of air in the pump housing can be got rid of in the water body.Adjusting or clamp nut (7) dwindle end play d and can reduce water percolating capacity.

In the utility model, the bearing (6) and the seal that support pump shaft are installed in the pump seat (5), make pump impeller be hung to darker water bottom by pump shaft, pump cover after pump line and pump seat are connected as a single entity, motor (10) flows to pump shaft with power by shaft coupling (8) after being fixed on support (9).Therefore, its drive mechanism is simple, and dynamic efficiency (kilogram oxygen/kilowatt hour) is higher than the aerator of other form.

The utility model device is compared with paddle aerator, and no reducing gear has reduced noise source, and is simple in structure, has avoided the pollution of leakage of oil to water body; The pump impeller tactical diameter is little, can run up; Compare with water-spraying oxygen-increasing machine, do not need submersible motor, thereby solved the difficult problem of leaking and leaking electricity, keep in repair also very convenient; And with compare to the method for water-bed injecting compressed air with air compressor machine or fan blower etc., no pipeline and spout need not optional equipment or devices, install and use and want much easy.

If can fix a point or local oxygen enriching to water body after being installed in oxygen increasing pump on the fixed mount, if can carry out portable oxygenation to each position of water body after being installed in it on ship or other buoyancy aid.

During oxygen increasing pump work, the air that has obtained kinetic energy and potential energy be directly be deep into water bottom and with water body between produce and to stir fully and mix, have oxygenation characteristics rapidly and completely, help the breeding growth of water bottom aerophile bacterium, quicken the oxidation and the decomposition of organic substance in the water body, purify water, also help simultaneously the normal growth of organism in the water body, so oxygen increasing pump not only can be used for the environment protection treating that aquaculture improves the living environment of organism but also can be used for wastewater and sewage.Oxygen increasing pump have stir and immixture also available it replace agitator or blender that various fluids (as gas and liquid) are mixed.Therefore, the utility model device will be widely used.
