Accompanying drawing explanation
The structural representation of the spiral jet aerator of nozzle that Fig. 1 provides for this utility model.
Detailed description of the invention
In order to make this utility model be solved the technical problem that, technical scheme and beneficial effect clearer,
Below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that herein
Described specific embodiment, only in order to explain this utility model, is not used to limit this utility model.
In conjunction with Fig. 1, this utility model provides a kind of spiral jet aerator of nozzle, including: fluidic chambers 1,
Mixing chamber 2 and diffuser pipe 3；
One end of fluidic chambers 1 is communicated with feed tube 1-1, and the other end of fluidic chambers 1 is jet orifice 1-2；Penetrating
The side of stream chamber 1 is communicated with suction nozzle 1-3；It addition, be also equipped with spirally spraying in the inside of feed tube 1-1
Mouth 1-4, the mouth spray of spiral nozzle 1-4 is towards the inner chamber of fluidic chambers 1, for the inner chamber of fluidic chambers 1
Injection liquid；
The jet orifice 1-2 of fluidic chambers 1 connects with the entrance of mixing chamber 2；The outlet of mixing chamber 2 and diffuser pipe
The entrance connection of 3.
The concrete structure of the spiral nozzle 1-4 that this utility model uses is: spiral nozzle 1-4 includes nozzle master
Body, nozzle body is communicated with nozzle inlet and nozzle ejiction opening；The inwall of nozzle body is provided with screw thread.
The length of mixing chamber 2 and diffuser pipe 3 is than for 1:1.
Drainage screen also it is installed with in the inlet position of feed tube 1-1.Drainage screen is stainless steel cloth.
Also include circulating pump；The inlet of circulating pump connects with bottom Aeration tank, the leakage fluid dram of circulating pump with enter
The inlet connection of liquid pipe 1-1；Inside Aeration tank, be also equipped with dissolved oxygen probes, diffuser pipe 3 outlet also
Pressure measuring instruments is installed；At the leakage fluid dram of circulating pump to the aqueduct between the inlet of feed tube 1-1
It is also equipped with electromagnetic flowmeter and electromagnetic valve；
