Abstract

This invention discloses a combined oxygen-increasing machine for aquaculture. In this machine, a motor is used to drive a high-pressure air machine, whose air outlet pipe is connected with a gas-storage bag. Air-bleeding pipes distributed on the air-storage bag are extended into a water body of a certain depth, and microporous air-exhaust pipes are connected with the ends of the air-bleeding pipes. The main axis of the high-pressure air machine is decelerated through a planet gear decelerator and an umbrella gear decelerator, and the output axis drives the slurry impeller. All the parts are installed on a frame, which is fixed with the buoy below so that the frame is floating on the water. The machine can increase the oxygen content in the water by the microporous air-exhaust pipes, and has such advantages as simple structure, few parts.

Description

Blade, aeration combined type automatic aerator

Technical field

The present invention relates to technical field of aquaculture, especially relate to a kind of oxygen-increasing device of aquaculture water.

Background technology

All kinds oxygenating machines such as vane type, water wheel type, water jet, water pump type, air-pump type are arranged at the oxygenating machine that uses at present, wherein vane type, water wheel type, water-spraying oxygen-increasing machine are with the disturbance surface water, increase the dissolved oxygen amount of surface layer of water, be difficult to improve the dissolved oxygen amount that certain depth water is arranged; The water pump type oxygenating machine, the energy disturbance has the water of certain depth, mixes with inhaled air, reaches the purpose of oxygenation, but the water flow of exit of pump ejection often has higher pressure, causes damage for the small fish shrimp; Air-pump type oxygenation function overcomes above-mentioned defective, as the roots blower oxygen-increasing device of import, is that unit is installed on the coast, air outlet tube is laid in advance in the water bodys such as pond, pond of breed, and the water body inflation to certain depth reaches the oxygenation purpose; But this apparatus cost is very expensive, and especially the cost of pipe laying is also expensive more many than unit valency, and the raiser is difficult to bear, and can't generally promote; For addressing the above problem, the applicant had once invented a kind of eddy flow, aeration combined type automatic aerator, publication number: CN1505250, it had both had impeller disturbance water body makes it to form eddy flow, discharge the micro-bubble inflation by the high pressure air pump to water body again, increase the contact area of water and air, reach the oxygenation purpose; Facts have proved that this oxygenating machine is better to the oxygenation effect of water body, be particularly suitable for the breed of fish, but for shrimps in culture,, tend to damage shrimp, so to shrimps in culture, this oxygenating machine is very unsuitable because of it is under water impeller high speed rotating.

Summary of the invention

The objective of the invention is in order to overcome the deficiency of above-mentioned prior art, a kind of blade, aeration combined type automatic aerator that is suitable for shrimps in culture is provided, it is simple in structure, parts are few, cost is low, and oxygenation effect is good, does not damage shrimp during running.

For achieving the above object, the technical solution used in the present invention is such: a kind of blade, aeration combined type automatic aerator, both be provided with high pressure positive blower and discharged the micro-bubble inflation to water body, increase the contact area of water and air, reach the oxygenation purpose, be provided with blade again, by rotating the oxygenation of paddle disturbance water body, because of paddle is in the disturbance of the shallow-layer water surface, can not damage the shrimp in the water body; Its concrete structure is such: comprise electric motor, high pressure positive blower, retarding mechanism, blade wheel, air storage bag, gas-distributing pipe and floating drum, directly drive the high pressure positive blower main shaft that is under the electric motor by motor output shaft, the air outlet tube of blower fan inserts the air storage bag, air storage is wrapped and is furnished with gas-distributing pipe, communicates with water body; The high pressure positive blower main shaft slows down through planet-gear speed reducer downwards, slow down through the crowngear step-down gear again, the output shaft that changes over the main shaft vertical direction directly drives the paddle wheel shaft, thereby blade wheel is rotated, the casing of said crowngear step-down gear is fixed on the frame, also be fixed with paddle wheel shaft axle bed on the frame, be used to connect the paddle wheel shaft; Frame has floating drum, and complete machine is suspended in the water surface; Said gas-distributing pipe leads under the water body, is distributed in radiation formula in the water body of certain depth, and the end of every pipe is connected to the micropore vapor pipe.

Owing to adopted technique scheme, paddle of the present invention, aeration combined type automatic aerator, simple in structure, parts are few, cost is low, have the characteristics of paddle formula and two kinds of oxygenating machines of inflatable concurrently, and do not need in the pond, to lay restrained line, be distributed in because of the air outlet on the water body of certain depth, so can improve the dissolved oxygen amount that the certain depth water body is arranged, along with the discharge of gas to the water surface, also increased contacting of upper water and air, improve the dissolved oxygen amount of upper water; The disturbance of paddle has more increased the contact area of shallow-layer water and air, and the The combined effect is so oxygenation effect is good; And from the micro-bubble of micropore vapor pipe discharge, and the disturbance of shallow seated groundwater, can not cause damage to shrimp, especially be fit to the breed of shrimps.
