Abstract
The utility model provides a kind of air bearing spray head, including sequentially connected spray head, connecting tube and flange, and the spray head includes the straight pipe and elbow of connection, and for the exit normal of the elbow in connecting tube axial direction, the straight pipe inner wall is provided with flight.When bubble enters in air bearing spray head, it is sufficiently mixed bubble at spiral flow and sewage by helical-blade, while fluid flows into air flotation tank distributor pipe at spiral-flow type.The utility model air bearing nozzle structure is simple, reasonable, which can make bubble formation spiral flow, and be sufficiently mixed with sewage.
Description
Technical field
The utility model relates to air flotation technology more particularly to a kind of air bearing spray heads.
Background technique
Air-flotation system fluid is directly entered in air flotation tank by Airfloat pump export pipeline at present, bubble and water in the fluid
Mixing is uneven, and the oil droplet in sewage cannot be attached on bubble completely, causes oil removal rate low, while fluid is deposited from Airfloat pump ejection
In gas and certain pressure, causes fluid fluctuation larger, be easily broken bubble, oil removal efficiency is low.
Utility model content
The purpose of this utility model is that the bubble sprayed for current air bearing spray head mixes non-uniform problem with water,
Fluid fluctuation is big, proposes a kind of air bearing spray head, which can make bubble formation spiral flow, and be sufficiently mixed with sewage.
A kind of in order to achieve the above purposes, the technical solution adopted by the utility model is: air bearing spray head, including it is sequentially connected
Spray head, connecting tube and flange, the spray head include the straight pipe and elbow of connection, and the exit normal of the elbow is in connecting tube axis
To the straight pipe inner wall is provided with flight.When bubble enters in air bearing spray head, by helical-blade make bubble at spiral flow with
Sewage is sufficiently mixed, while fluid flows into air flotation tank distributor pipe at helical flow.
Further, the air bearing spray head is casting integrated formula.
Further, the flight pitch P and length L is how many with oil content and transfer, the flight pitch are spiral shell
0.1~1000 times of vane diameter d, helix length L are 0.1~1000 times of screw pitch；Sewage quantity is handled not according to air-flotation system day
Together, flight diameter d is how many with treating capacity and transfer, flight diameter d are 1mm-1000mm.
Further, flight pitch is 0.5-20 times of helical-blade diameter d.
The utility model air bearing nozzle structure is simple, reasonable, has the advantage that compared with prior art
The straight pipe inner wall of the utility model air bearing spray head is provided with flight, when fluid enters in spray head, passes through spiral
Leaf is sufficiently mixed bubble at spiral flow and sewage, while fluid flows into air flotation tank distributor pipe at helical flow.
The straight pipe inner wall of the utility model air bearing spray head is provided with flight, when fluid enters in spray head, passes through spiral
Leaf forms spiral flow, makes fluid uniform force, guarantees that bubble is not ruptured into air flotation tank.
Detailed description of the invention
Fig. 1 is the utility model air bearing nozzle structure schematic diagram.
Specific embodiment
The present invention will be further described with reference to embodiments:
Embodiment 1
Present embodiment discloses a kind of air bearing spray heads, as shown in Figure 1, including sequentially connected spray head 1, connecting tube 2 and method
Orchid 3, the spray head 1 include the straight pipe and elbow of connection, and the spray head is casting integrated formula.The exit normal of the elbow in
Connecting tube is axial, and the straight pipe inner wall is provided with flight.When bubble enters in air bearing spray head, by helical-blade make bubble at
Spiral flow is sufficiently mixed with sewage, while fluid flows into air flotation tank distributor pipe at spiral-flow type.
The flight pitch P and length L is how many with oil content and transfers, and the flight pitch is helical-blade diameter d
5 times, helix length L is 1 times of screw pitch or more；According to handling air-flotation system day, sewage quantity is different, and flight diameter d is with treating capacity
How many and transfers, flight diameter d is 1mm-1000mm.
Embodiment 2
Present embodiment discloses a kind of air bearing spray heads, and structure is substantially the same manner as Example 1, the difference is that the flight
Screw pitch is 10 times of helical-blade diameter d, and the helix length L is 3 times of screw pitch.
Finally, it should be noted that the above various embodiments is only to illustrate the technical solution of the utility model, rather than it is limited
System；Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should
Understand: it is still possible to modify the technical solutions described in the foregoing embodiments, or to some or all of
Technical characteristic is equivalently replaced；And these are modified or replaceed, it does not separate the essence of the corresponding technical solution, and this is practical new
The range of each embodiment technical solution of type.
