Abstract
The utility model belongs to an improved impeller of an impeller type oxygen increase machine of a fish pond. The utility model is characterized in that the vent pipe of the prior art is cancelled, a row of suction holes are arranged on the conical face of an impeller body in the back pressure face of a water shifting plate along radical direction, and the water shifting plate is aslant arranged towards rotary direction. The utility model which is especially suited to be used by the impeller type oxygen increase machine of the fish pond has the advantages of simple and light structure, low cost and good oxygen increase effect.
Description
The utility model belongs to aquaculture machinery, particularly a kind of improved vane type oxygen-enriching machine in fish pond impeller.
At present, existing both at home and abroad multiple fish pond oxygen-increasing device, vane type oxygen-enriching machine in fish pond wherein, strong with its oxygen transfer rate, the small power, easy to use and be widely used.In prior art, impeller that the vane type oxygen-enriching machine in fish pond is used and structural similarity illustrated in figures 1 and 2.Figure 11 is the impeller front view of Guangdong Province's Shunde County second machine reparation factory, and Fig. 2 is along the cutaway view of A-A line among Fig. 1.During use, impeller is by floating drum and bracket supports, place in dried up 2～2.5 centimetres the water,, make and be fixed in the water extraction board (2) that is the polylith that radiation distributes on the shape of the falling Cone impeller body and rotate and stir water through the deceleration device driven rotary of slowing down by motor, cause water sports on the one hand, the dissolved oxygen that changes water body distributes, a large amount of sprays of kicking up on the other hand carry out aeration, the dissolved oxygen amount in the water body that increases sharply.Meanwhile, be positioned at the breather pipe (3) that is fixed between two water extraction boards (2) on the impeller body (1), utilize when rotating in the stronger negative pressure of the behind of its rotation direction formation, suck a large amount of air from the mouth of pipe and inject water through back pressure hole, the dissolved oxygen amount of water body that increases sharply, thus reach the purpose of oxygenation.The weak point of this blade wheel structure is: utilize breather pipe (3) oxygenation, effect is limited, has increased impeller weight and production cost on the contrary; The plane of water extraction board (2) is by the center line of impeller, and promptly water extraction board (2) does not tilt towards rotation direction, and in stirring the water process, water does not produce downward partial pressure to water extraction board (2), and it is not high to pump up water, and floats easily again, influences oxygenation effect.
The purpose of this utility model is to overcome the deficiency of prior art, provides a kind of structure light and handy, the vane type oxygen-enriching machine in fish pond impeller that oxygen transfer efficiency is high.
The purpose of this utility model can realize by following measure: the breather pipe (3) of cancellation prior art, radially open row's suction hole (1a) on impeller body (1) the Cone face in water extraction board (2) back pressure face, produce stronger negative pressure at its back pressure face when utilizing water extraction board (2) to rotate, from suction hole (1a), suck air and inject the dissolved oxygen amount that water increases water; Water extraction board (2) is obliquely installed towards direction of rotation, and when making wheel rotation, water body produces a downward partial pressure to water extraction board (2), avoids the impeller come-up, increases oxygenation effect.
The drawing of accompanying drawing is described as follows:
Fig. 3 is the front view of the utility model concrete structure.
Fig. 4 is along the cutaway view of B-B line among Fig. 3.
Fig. 5 is along the partial sectional view of C-C line among Fig. 4.
In the accompanying drawings, (1) is impeller body, and (2) are water extraction board, (1a) is suction hole.The diameter of suction hole (1a) with 4～8 millimeters for well, its number is suitable with 4～10.Diameter is meticulous or number is very few, and inspiratory capacity is low, and diameter is excessive or number is too much, also can reduce the negative pressure in back pressure district, influences inspiratory capacity.Angle α=10～20 on water extraction board (2) and the plane of crossing the impeller axis ° are for well, when very few effect not obvious, when excessive, water body increases the downward actuating pressure of water extraction board (2), impeller sinks too much, also influences and raises effect.
The utility model has following advantage compared to existing technology: simple in structure light and handy, save steel, reduce cost, improve oxygen transfer efficiency, from 1.7 kilograms of oxygen of 1.4～1.5 kilograms of original oxygen/kilowatt-hour bring up to/kilowatt-hour, improve 13～21%.
Claims (3)
1, one mainly by impeller body (1) be the vane type oxygen-enriching machine in fish pond impeller that polylith water extraction board (2) that radiation distributes is formed, it is characterized in that radially opening one and arrange suction hole (1a) on impeller body (1) conical surface of water extraction board (2) back pressure face; Water extraction board (2) is obliquely installed towards direction of rotation.
2, oxygen increasing machine impeller according to claim 1 is characterized in that every row's suction hole is 4～10, and diameter is 4～8 millimeters.
3, oxygen increasing machine impeller according to claim 1 is characterized in that angle α=10～20 ° on water extraction board (2) and the plane of crossing the impeller axis.
