Same or similar element or element with the same or similar functions are indicated to same or similar label eventually.Below by ginseng
The embodiment for examining attached drawing description is exemplary, and is only used for explaining the utility model, and cannot be construed to the utility model
Limitation.
In Fig. 1 and Fig. 2, totally enclosed type swirl reinforced dissolved gas floatator, mainly by closed shell 2 and molten gas
6 composition of pump.Shell 2 is internally provided with the central channel 11 being fixedly connected by connecting plate 10 with 2 inner wall of shell, and air dissolved pump 6 exports
It is connected by pipeline with air-dissolving air-float release 5, air-dissolving air-float release 5, which is mounted on, is fixed on air floatation machine by connecting plate 10
11 lower section of central channel on 2 inner wall of totally enclosed type shell, connecting plate 10 are equipped with connecting hole 3, and tapered knot is designed in 2 bottom of shell
Structure, 2 bottom of shell are connected by pipeline with outfall sewer line 7, and 7 one tunnel of outfall sewer line passes through pipeline and 6 import of air dissolved pump
It is connected, another way is connected by pipeline with clear water output 14, and the shell 2 of 10 lower section of connecting plate is equipped with and helical structure 4
The wastewater inlet 13 of connection, helical structure 4 can make the sewage in wastewater inlet 13 form cyclonic action, pass through centrifugal principle point
From different densities medium.Waste residue is connected by being located at the pipeline 1 of slagging tap of 11 bottom of central channel with waste residue outlet 12.
It is provided with signal wire on pipeline between outfall sewer line 7 and clear water output 14 and is mounted on 2 bottom of shell
The electric press regulating valve 8 that pressure sensor 9 on tapered surface is connected.Pressure sensor 9, which changes 2 internal pressure of shell, to be believed
It number feeds back in the electric press regulating valve 8 of clear water output 14, and by the size of control valve aperture to 2 internal pressure of shell
It is adjusted, thus holding meanss inner pressure constant.
As a kind of improvement of the utility model, 2 cross section of shell is circle, and central channel 11 is cylindrical structure.Connecting hole 3
It is along the circumferential direction evenly distributed on connecting plate 10.
The utility model includes following workflow:
Preliminary eddy flow product process: sewage enters wastewater inlet 13 by external elevator pump etc., and wastewater inlet 13 is located at gas
The waterpower space collectively constituted in floating machine closed shell by 10 lower surface of connecting plate, 11 outer surface of central channel and 2 inner wall of shell
Part, and with eddy flow generate helical structure 4 connect make sewage entrance after form the eddy flow state flowed up.
Dissolved air flotation process: under the action of the sewage after cyclonic separation recycles in air bearing, make isolated impurity by
The micro-bubble that air bearing is formed is brought to connecting hole 3(waste residue space-waterpower space connecting pipe at the top of waterpower space segment).
Clear water after eddy flow product process and dissolved air flotation process collective effect is passed through clear by waterpower space segment bottom outfall sewer line 7
Outside 14 discharger of water out.Meanwhile part clear water introduces dissolved air flotation process by 7 branch line of air floatation machine outfall sewer line
Form circulation in new air bearing.
Deslagging process: the waste residue assembled at the top of waterpower space segment is by connecting hole 3(waste residue space-waterpower space connecting tube
Road) enter the waste residue space being made of 10 upper surface of connecting plate, 2 inner wall of shell and 11 inner surface of central channel, it is closed in air floatation machine
