Abstract
The utility model relates to a rotary spraying aerator which is composed of a motor (1), a bearing seat (2), an air inlet (3) on a main shaft, a bearing (4), the main shaft (5), an air outlet (6) on a screw propeller, the screw propeller (7), a bracket (8) for a flow guiding cylinder, the flow guiding cylinder (9), a rotary spraying shaft (10), a rotary spraying cylinder (11), a spout (12), a supporting shaft (13) for the rotary spraying cylinder, a bracket (14), and mounting holes (15) for adjusting the bracket to be higher. The rotary spraying aerator is characterized in that the outer edge of the screw propeller (7) is sheathed with the flow guiding cylinder (9) which is connected with a machine frame (14) by the bracket (8), the flow guiding cylinder (9) is connected with the rotary spraying cylinder (11) by the rotary spraying shaft (10), and the rotary spraying cylinder (11) rotates around the flow guiding cylinder (9). The utility model has simple structure and can increase the oxygenation area, and the structure of the bracket and double spraying cylinders enables the rotary spraying aerator to work stably.
Description
The utility model relates to a kind of liquid oxygen-increasing device.
Existing oxygenating machine is made up of floating drum, motor, oxygenation bubble generator, fixed spout, this oxygen-increasing device, and on bubbling through the water column with floating drum, the cost height is difficult for mooring, and is fixing, and the oxygenation region area in the fixing spray is little, and efficient is low.
The purpose of this utility model provides a kind of rotary ejection type oxygenating machine, and it can remedy the above-mentioned deficiency of existing oxygenating machine.
The utility model machine organic frame, motor, main shaft, main shaft air inlet port, propeller, propeller production well, guide shell, churning tube are formed, and it is characterized in that connecting the churning tube in the lower end of guide shell by the churning axle, and two spouts of the latter are certain angle mutually.
The spout rotation can increase oxygenation area greatly when the utility model and existing its advantage of oxygenating machine comparison were oxygenation, and simple in structure, and rack-like structures and bispin spray tube operate steadily.
Below by embodiment and description of drawings the utility model.
Accompanying drawing 1 is the main existing structural representation of going out of this practical embodiment.
Accompanying drawing 2 is the plan structure synoptic diagram of an embodiment of the utility model.
The utility model comprises that its top of a frame (14) has bearing support (2) latter top to adorn an electric motor (1), the output shaft of electric motor (1) links to each other with main shaft (5), the latter is connected with frame (14) by bearing (4), a propeller (7) is fixed in the lower end of main shaft (5), main shaft (5) is an open tube, its upper end has main shaft inlet mouth (3), the latter is communicated with propeller production well (6) by main shaft (5) cavity, propeller (7) outer rim is with guide shell (9), the latter is fixing by guide shell support (8) and frame (14), and the lower end of guide shell (9) links to each other with churning tube (11) by churning axle (10).Therefore, churning tube (11) can freely rotate around guide shell (9), and vertical steering bracket open holes (15) is arranged at frame (14) bottom.
During the oxygenation operation, at first the utility model is placed water, make frame (14) top mutually neat,, make frame increase suitably height if the depth of water can be regulated support with bolting by the vertical steering bracket open holes (15) on the frame (14) with horizontal plane; After mixing up height, connect with the mains, actuating motor (1) electric motor (1) drives propeller (7) rotation by main shaft (5), water is sucked row to rotating cylinder (11) from guide shell (9) upper end, the paddle back side produces negative pressure simultaneously, paddle back side negative pressure is less than a normal atmosphere after propeller (7) reaches certain rotating speed, air is by main shaft air inlet port (3), main shaft (5) cavity and propeller production well (6) enter the paddle negative pressuren zone, then smashed, mix forming the current that contain a large amount of bubbles with current by the paddle of high speed rotating; Current rush at churning tube (11), because the latter's spout (12) face and churning tube (11) are certain angle with the face that main shaft (5) constitutes, so churning tube (11) is under the hydro-flow thrust effect, rotate around guide shell (9) by churning axle (10), it is the center of circle that current form with the main axis, with two-way jet length is the oxygenation face of diameter, owing to open on closing bubble in water and being, so current of common directional type oxygenating machine, can only be along the water mark oxygenation of a fixed range, oxygenation area is limited, and a utility model can utilize bubble to residue in the principle of for some time in the water, the rotation jet flow, its efficiency far is greater than ordinary fixed spray (stream) mouthful oxygenating machine.
Claims (1)
1, a kind of rotary ejection type oxygenating machine, motor (1) is arranged, bearing support (2), main shaft (5), propeller (7), frame (14), guide shell (9) has air inlet port (4) and production well (6) on main shaft (5) and propeller (7), it is characterized in that being with guide shell (9) in propeller (7) outer rim, the latter is connected with frame (14) by support (8), and guide shell (9) connects churning tube (11) by churning axle (10), and churning tube (11) rotates around guide shell (9).
