Technical Field
[0001] The utility model relates to the technical field of aeration flow pushers, in particular to a rotary blast type aeration flow pusher. Background Art
[0002] After the end of the aeration flow propeller is put into the water, it faces one side and forms negative pressure through the rotation of the blades, so that the air on the liquid surface is sucked into the water along the air pipe and discharged to one side along the water flow caused by the rotation of the blades, so that the air is pumped into the water and fully contacts the water to realize the aeration function. However, when the existing blades rotate too fast, relying solely on the pipe connected to the upper part of the liquid surface to suck air is not enough to provide enough air for the efficient operation of the equipment. Utility Model Content
[0003] The technical problem to be solved by the utility model is to provide a rotary blast aeration flow propeller in response to the above-mentioned technical deficiencies. Air is blown into the air inlet pipe through a blower at the upper part, and then the air is output along the hollow shaft in the middle of the blade, thereby finally improving the high-efficiency aeration efficiency of the equipment. Further, through the aeration membrane around the hollow shaft, the air is blown in and then blown out along the aeration membrane, and then blown out to one side through the blade. During the blowing process, the air that has been blown out from the aeration membrane forms small bubbles and is continued to be blown out, thereby increasing the contact area between air and water and improving the aeration efficiency.
[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: it includes a motor and a transmission shaft connected to the motor output shaft, a sleeve is provided on the outer side of the transmission shaft, and a reducer is connected to the end of the transmission shaft, and a blade is connected to one side of the reducer; the power output shaft of the reducer is a hollow shaft, and the blade shaft is connected to the hollow shaft; an air intake pipe is provided above the liquid surface; the end of the air intake pipe is connected to the blower; the air intake pipe extends downward to one side of the reducer to provide an air intake chamber; the inner cavity of the air intake chamber is connected to the hollow shaft, and the hollow shaft extends to the outer part of the blade and the side walls are provided with a first aeration membrane.
[0005] To further optimize the technical solution, the blades are installed on the side of the reducer and are arranged vertically in the horizontal direction.
[0006] To further optimize the technical solution, positioning ropes are fixed between the outer walls on both sides of the middle part of the casing and the ground.
[0007] To further optimize the technical solution, the end of the hollow shaft relative to the first aeration membrane extends into the inner cavity of the air inlet chamber.
[0008] To further optimize the technical solution, the end of the hollow shaft relative to the first aeration membrane extends outside the air inlet chamber, the end of the hollow shaft located outside the air inlet chamber is connected to the second aeration membrane, and the hollow shaft is rotatably sealed to the side wall of the air inlet chamber.
[0009] To further optimize the technical solution, an air inlet is provided on the tube body of the hollow shaft located in the inner cavity of the air inlet chamber, and the air inlet is connected to the inner hollow cavity of the hollow shaft.
[0010] Compared with the prior art, the utility model has the following advantages: air is blown into the air inlet pipe through the blower at the upper part, and then the air is output along the hollow shaft in the middle of the blade. This structure advantageously ensures that the high aeration efficiency of the equipment is finally improved. Further, through the aeration membrane around the hollow shaft, the air is blown in and then blown out along the aeration membrane, and then blown out to one side through the blade. During the blowing process, the air that has been blown out from the aeration membrane forms small bubbles and continues to be blown out, thereby increasing the contact area between air and water and improving the aeration efficiency.
