Abstract

The utility model relates to an aeration appliance for aquaculture industry, primarily, the lower end of a rotation shaft is provided with a wind restoring device which is composed of a hollow shaft, a conical surface water blocking plate, a plurality of blades and a plurality of vent pipes, wherein, the outer margin of the lower end of the hollow shaft is connected with the central hole of the lower end of the conical surface water blocking plate, a plurality of blades are connected with the upper part of the outer margin of the conical surface water blocking plate uniformly and slantwise, and the lower end of a plurality of vent pipes is communicated and connected with the conical surface water blocking plate arranged at the back of corresponding blades. Thereby, the oxygen amount entering in water is added.

Description

Has the aerator that adds wind formula impeller

The utility model relates to the oxygen increasing equipment that uses in a kind of aquaculture industry.

At present, common paddle aerator is directly or through decelerator impeller sheet to rotate in water with motor, mixes with water and produce the negative pressure oxygen intake, and still, it is less to draw amount of oxygen in the water.In the recent period also begin directly to open air flue or connect breather pipe on the hollow shaft of impeller, enter oxygen-supplying amount in the water with increase, still, effect is still not ideal enough.

In view of this, the purpose of this utility model provides a kind of aerator that adds wind formula impeller that has, and it is to utilize on the taper seat water fender that is connected the rotating shaft periphery corresponding inclination breather pipe and blade are set, and increases the amount of oxygen that enters in the water.

The purpose of this utility model is achieved in that it comprises floating seat, motor, rotating shaft, it is characterized in that: be provided with in the rotating shaft lower end by what a hollow shaft, a taper seat water fender, several pieces blades and several breather pipe constituted and add wind apparatus, its hollow mandrel upper end is connected with the rotating shaft lower end, taper seat water fender lower end centre bore is connected with hollow shaft lower end outer rim, and taper seat water fender upper end gusset is connected with the hollow shaft outer rim; Several pieces blades evenly are connected taper seat water fender outer rim top obliquely; Several breather pipes pass through in the taper seat water fender that is connected the respective vanes back obliquely mutually with its lower end.

Described hollow shaft lower end is provided with an end plug.

Described breather pipe upper end has conical wind scoop.

Described blade and breather pipe are more than at least 3.

Because adopt such scheme: when the taper seat water fender of rotation churned the surface blade, air poured the water from breather pipe, increase the amount of oxygen that enters in the water greatly.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 the utility model exemplary embodiments schematic diagram.

The A-A cutaway view of Fig. 2 the utility model exemplary embodiments Fig. 1.

Among the figure: 1, floating seat, 11, supporting base, 12, overhanging floating drum, 2, motor, 21, motor cover, 3, rotating shaft, 4, add wind apparatus, 41, hollow shaft, 411, end plug, 42, the taper seat water fender, 421, gusset, 43, blade, 44, breather pipe, 441, wind scoop.

Present embodiment comprises floating seat 1, motor 2, rotating shaft 3 and adds wind apparatus 4, as shown in Figure 1, and wherein:

Floating seat 1 is to be made of three uniform overhanging floating drums [2 are supported in supporting base] 1 (in establish bearing), on supporting base 11, support the motor 2 of waterproof machine cover 21 in addition, connect a rotating shaft 3 with shaft coupling and be bearing in the supporting base 11 at the axle head of this motor 2, rotate synchronously with motor 2, all belong to prior art.

Adding wind apparatus 4 is to be made of hollow shaft 41, taper seat water fender 42, blade 43 and breather pipe 44, shown in Fig. 1～2, this adds wind apparatus 4 and is connected rotating shaft 3 lower ends with hollow shaft 41 upper ends, and hollow shaft 41 lower ends are blocked with end plug 411 (as: screw adds seal), enter with waterproof; Taper seat water fender 42 is connected hollow shaft 41 outer rim lower ends with its lower end centre bore, and taper seat water fender 42 upper ends connect on hollow shaft 41 outer rims with a gusset 421 (as: digging porose flat board); Several pieces blades 43 are arranged on taper seat water fender 42 outer rim tops (by taper seat major part section) in uniform way, and this blade 43 and about 60 ° of taper seat tangent plane inclinations, reduce the resistance of blade 43 in water; Several breather pipes 44 pass through connection with the lower end obliquely mutually with taper seat thing plate 42 corresponding holes, and breather pipe 44 upper ends have conical wind scoop 441 and stretch out in taper seat water fender 42, to increase intake, and breather pipe 44 is located with the position (being the phase perforation) that taper seat water fender 42 passes through connection mutually, in corresponding dihedral vane 43 back.

The operation principle of present embodiment is as follows:

When the motor 1 of floating seat 1 with the buoyancy support of the water surface, drive hollow shaft 41 clockwise directions through rotating shaft 3 and rotate (direction of arrow in as Fig. 2), blade 43 produces vortex in water, air above vortex produces negative pressure, and breather pipe 44 rotates in air, forces air to enter breather pipe 44, and enters in the water with vortex in the water, and can fully mix with water, reach the compulsory oxygen aeration effect.
