The web wheel type oxygen increasing machine comprises a motor, a gear cavity, a driver and a floating body, two ends of the motor cavity is the gear cavity, the driver is connected with the gear cavity, a shaft is arranged on the outside of each driver, more than one web wheel is arranged on each shaft along the axial line, the two driver is arranged on the stent, the stent is connected with two floating body. The utility model has advantages of good oxygen increasing effect, energy and electricity saving, large plug-flow range, low culture cost and simple and reliable structure, which can be used for oxygen increasing in various aquatic products breeding industry.

Description

The wheeled aerator of web

Technical field

The utility model relates to aquatic products kind aquaculture with machinery, relates in particular to a kind of aquatic products kind aquaculture and carries out the wheeled aerator of web that oxygenation is used.

Background technology

For aquatic products kind aquaculture, the quality of bleeding technique is the important factor whether the decision aquaculture has a good harvest, culture at present the oxygen supply equipment great majority that adopt in the place under water and be Waterwheel-type or paddle aerator, this equipment is to strike waters with the driven by motor blade, make the water on the water surface form bubble by falling into the water in the air, by the bubble oxygen supply, but there is following weak point in this equipment: owing to adopt the oxygen supply that strikes waters, need powerful driven by motor, waste energy; Because only pat at the water surface, the drowning degree of depth has only about 10 centimetres, can't be to the depths oxygen supply in addition.

The utility model content

At the deficiency that prior art exists, the purpose of this utility model be to provide a kind of can be to the wheeled aerator of the web of oxygen supply of depth of water place and energy saving.

In order to achieve the above object, the utility model has adopted following technical proposals:

The wheeled aerator of the utility model web is the bleeding technique that utilizes traditional waterwheel principle, animal web claw type formula and modern science and technology to organically combine.

The main frame of the wheeled aerator of web comprises motor, gear cavity and driver etc., is assembled into an integral body along axis.The two ends of described motor cavity are gear cavity, and gear cavity is connected with driver, and respectively there is a shaft extension in the driver outside, and more than one web wheel is arranged on each shaft extension, have footing to be installed on the support on the main frame, and support connects two buoyancy aids.

Described motor is loading type capacitor start (comprising capacitor operating) monopole asynchronous motor or threephase asynchronous, and its shell adopts can resist the protection form of water logging.Even motor falls into water accidentally, at the appointed time with pressure under, motor can not encroached on, and has reached IP x 7 requirements of GB and International Power association criterion regulation.Described gear cavity adopts bidentate wheel secondary helical cut gear speed system, working stability, and anti-resistance is strong around ability.

The operation principle of the utility model aerator is by the rotation of web wheel, one side forms countless micro-bubbles rapidly in water, contain carbonic acid gas in a large amount of water, one side is thrown to current in the air, discharge, dissolve into sufficient oxygen simultaneously, under huge thrust, push the heavy-oxygen-enriched water that falls to far-end and depths.According to the number of web wheel number, promotion scope the best can reach about 150 meters, raises up to 1.8 meters, influences the depth of water and can reach below 3 meters, can be in three layers of oxygenation simultaneously of upper, middle and lower.

The utlity model has that oxygenation effect is good, energy saving, the plug-flow scope is big, aquaculture cost is low, advantage such as simple and reliable for structure.Carrying out oxygenation for various aquatic products kind aquacultures uses.

Embodiment

The utility model is described in further detail below in conjunction with drawings and the specific embodiments:

Embodiment

As shown in Figure 1, the main frame of the wheeled aerator of web, comprise motor 5, gear cavity and driver 2 etc., two ends are gear cavity in described motor 5 chambeies, gear cavity is connected with driver 2, and respectively there is a shaft extension in driver 2 outsides, the more than one web wheel 1 of assembling on each shaft extension, main frame 2 is installed on the support 6, and support connects two buoyancy aids 7.

Motor 5 is monopole asynchronous motor or threephase asynchronous, electromotor is through optimal design specially and meticulously, motor performance is good, the stifled moment of anti-resistance is big, starting voltage is low, even the net capacity deficiency, when the big or voltage of voltage pulsation caused voltage drop to be low to moderate 160V (single-phase) or 300V (three-phase) away from the job site, motor also can normal starting.

Web wheel 1 utilizes bionics principle to be designed to animal web claw type formula, pocket water rate height, and oxygen transfer rate is strong, the dynamic efficiency height.Dynamic efficiency is that every kilowatt-hour of aerator makes the increment that contains oxygen content amount in the water of the pool.Have measured data to show, it is compared with the waterwheel aerator impeller, under identical oxygen transfer rate, can save a large amount of electricity consumptions.

The operation principle of the utility model aerator is by 1 rotation of web wheel, one side forms countless micro-bubbles rapidly in water, contain carbonic acid gas in a large amount of water, one side is thrown to current in the air, discharge, dissolve into sufficient oxygen simultaneously, under huge thrust, push the heavy-oxygen-enriched water that falls to far-end and depths.

Claims

1, the wheeled aerator of a kind of web, comprise motor, gear cavity and driver etc., be assembled into an integral body along axis, it is characterized in that: the two ends in the described motor cavity are gear cavity, gear cavity is connected with driver, and respectively there is a shaft extension in the driver outside, and more than one web wheel is housed on each shaft extension, have footing to be installed on the support on the main frame, support connects two buoyancy aids.
