Fig. 2 is the vertical view of the utility model.
Specific implementation mode
The technical solution of the utility model is further detailed below by way of specific implementation mode combination attached drawing and
Description.
As illustrated in fig. 1 and 2, a kind of jet mixing aerator, including a mixed liquor distribution cavity 1 and an air distribution chamber 2,
Air distribution chamber 2 is covered in outside mixed liquor distribution cavity 1.
There is a mixed liquor to be pumped into pipe 10 for the lower end of mixed liquor distribution cavity 1, and there is a connection to rouse for the upper end of air distribution chamber 2
The air intake pipe 20 of wind turbine (not shown), the lower end that mixed liquor is pumped into pipe 10 are connected with a mixed liquor and are pumped into interface tube method
Orchid 101, the upper end of air intake pipe 20 is connected with an air intake pipe flange 201；
Mixed liquor distribution cavity 1, which has, is spacedly distributed in the middle part of its cavity wall and is connected to mixed liquor distribution cavity 1 and air distribution
8 jet nozzles 11 (number is determined 3~20 according to technological parameter) of chamber 2, the injection direction of several jet nozzles 11 is equal
Downwards with level be in 0~45 degree angle, air distribution chamber 2 have connection air distribution chamber 2 and outside and with above-mentioned several jet streams
The corresponding several mixed spray tubes 21 with one heart of nozzle 11；Have between above-mentioned several jet nozzles 11 and several mixed spray tubes 21
The air for being connected to air distribution chamber 2 sucks gap 3.
The length L1 of mixed spray tube 21 is 250-300mm；Diameter D1 is 36-50mm, D2 40-60mm.Air sucks
The length L2 in gap 3 is 35-45mm.The length L3 of jet nozzle 11 is 50-65mm, and the inlet diameter D4 of jet nozzle 11 is
The throat pipe diameter D3 of 40-50mm, jet nozzle 11 are 20-30mm.
When operation, after jet pump extracts the pressurization of aeration tank mixed liquor, the mixed liquor for being pumped via pipes into the utility model is pumped into
Pipe 10 is uniformly distributed to 8 jet nozzles 11, and spray from the trunnion of 11 end of jet nozzle to mixed liquor distribution cavity 1, high
The liquid stream of speed makes to form local negative pressure at air sucking gap 3, so that the air in air distribution chamber 2 is inhaled into, part is molten
Solution is partly divided into a large amount of small bubbles by liquid stream, becomes gas liquid mixture in mixed liquor.Gas liquid mixture is sprayed through mixing
The discharge of pipe 21 is penetrated, strong injection stream is formed, realizes the function of oxygenation and water conservancy stirring.
The above, the only preferred embodiment of the utility model, therefore the utility model implementation cannot be limited according to this
Range all should still belong to this practicality that is, according to equivalent changes and modifications made by the utility model patent range and description
It is novel cover in the range of.
