Description
Technical field
The present invention relates to a kind of centrifugal submersible aerators, belong to technical field of sewage.
Background technique
The structure of centrifugal submersible aerator is associated mode, and product is self-priming aeration, what high-speed rotating impeller generated
Centrifugal force forms extremely strong negative pressure sucking air and water at impeller inlet, by a certain proportion of mixing wastewater with air in mixing chamber,
Under powerful centrifugal force effect, the tangential direction along impeller is spouting through runner, spreads to circumferencial direction, keeps water flow pairs of
Stream circulation, and micro-bubble fine crushing its large specific surface area, the rate of climb is slow, and guarantee sufficiently mix with water, to reach height
Imitate the effect of oxygenic aeration.
But during handling sewage, the things such as water plant, polybag can wind impeller, can often block at impeller inlet,
Aerator aeration efficiency is caused to reduce even damage aerator.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the deficiencies of existing technologies, a kind of centrifugal underwater jet aeration is provided
Machine avoids sundries clogging impeller entrance.
In order to solve the above technical problems, the present invention provides a kind of centrifugal submersible aerator, including aerator ontology, it is described
Aerator ontology includes submersible machine (1), impeller (2), mixing pan (3), air inlet pipe (4), bracket (5) and inlet plenum (6), institute
Submersible machine (1) connection impeller (2) is stated, impeller (2) is located in mixing pan (3), and submersible machine (2) passes through cable (7) and external
Power supply connection, the air inlet pipe (4) connect with inlet plenum (6), and inlet plenum (6) is located at below mixing pan (3), the bracket (5)
The bottom for being located at aerator ontology plays a supportive role；The surrounding of the blade of the impeller (2) is equipped with several cutter heads (8).
Further, the cutter head (8) uses antirust composition cutter head.
Further, the cutter head (8) and impeller are integrally formed.
Further, the top of the air inlet pipe (4) is equipped with muffler (9).
Further, the air inlet pipe (4) is equipped with electronic flow control valve (10), wirelessly connects with control equipment on the bank
It connects, air inflow is controlled by control equipment.
Further, further include dissolved oxygen sensor, be located in sewage, and connect the control equipment, sensed according to dissolved oxygen
The information of device acquisition passes through control equipment automatic adjustment electronic flow control valve (10).
Advantageous effects of the invention:
By on impeller be arranged cutter head sundries is cut, prevent sundries winding impeller or sundries it is excessive block impeller into
At mouthful, avoid damage aerator that from can also improving the efficiency of aerator and improve service life.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
The area A therein is perspective view, illustrates impeller 2 for facilitating.
Specific embodiment
