Abstract

Disclosed is a paddle and inflation combined type automatic aerator for aquaculture. A motor drives a high-pressure draught fan, a duct outlet of the draught fan is connected in a gas-storing package which is distributed with gas-distributing pipes penetrating into water body, and the gas-distributing pipes are evenly distributed in water body with certain depth in radial type, with the end of the every gas-distributing pipe connected with a micropore discharge pipe. A main shaft of the high-pressure draught fan is decelerated through a planetary gear speed reducer and an umbrella type gear speed reducer, and an output shaft drives a paddle wheel shaft after changing direction. Every component is arranged on a stand which is fixed with a float bowl arranged below the stand, which makes the integral machine float on the water surface. The paddle and inflation combined type automatic aerator of the utility model achieves simple structure, less components, low cost and the characteristics of a paddle-type automatic aerator and a inflatable automatic aerator, without needing to lay fixed pipes in pool, and the aeration effect is great. Microsize air bubbles discharged from the micropore discharge pipes and stirring of the paddle to shallow water can not destroy shrimps, and the paddle and inflation combined type automatic aerator is particularly applicable to cultivating shrimps.

Description

Blade, aeration combined type automatic aerator

Technical field

The utility model relates to technical field of aquaculture, especially relates to a kind of oxygen-increasing device of breeding water body.

Background technology

All kinds aerators such as vane type, Waterwheel-type, water jet, water pump type, air-pump type are arranged at the aerator that uses at present, wherein vane type, Waterwheel-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 aerator, 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, discharge pipe 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 tubing 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 aerator 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 aerator is very unsuitable because of it is under water impeller high speed rotating.

Summary of the invention

The purpose of this utility model 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 to be provided, and 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 adopted in the utility model 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 paddle 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 electromotor, high pressure positive blower, reducing gear, blade wheel, air storage bag, gas-distributing pipe and floating drum, directly drive the high pressure positive blower main shaft that is under the electromotor by motor output shaft, the discharge pipe 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 bevel gear reductor 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 bevel gear reductor 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 radiant type in the water body of certain depth, and the end of every pipe is connected to the micropore blast pipe.

Owing to adopted technique scheme, paddle of the present utility model, aeration combined type automatic aerator, simple in structure, parts are few, cost is low, have the characteristics of paddle formula and two kinds of aerators of inflatable concurrently, and do not need in the pond, to lay fixed-piping, be distributed in because of the gas 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 blast pipe discharge, and the disturbance of shallow seated groundwater, can not cause damage to shrimp, especially be fit to the breed of shrimps.
