An object of the utility model is to provide an air supporting effect is better dissolves gas air supporting machine.
Description
Technical field
This utility model relates to a kind of air floatation machine, more specifically, it relates to a kind of high-efficiency dissolued-air air floatation machine.
Background technology
Air floatation machine is a kind of machine that purifies, and a kind of applies air supporting method to carry out the equipment of water process.It it is the micro-bubble forming high degree of dispersion in water, adhere to solid or the liquid particles of hydrophobic group in waste water, form water-gas-granule three-phase mixed system, after particle adhesion bubble, form apparent density and float to the water surface less than the flco of water, formation scum layer is stripped off, thus realizes the process of solid-liquid or Liquid liquid Separation.
Making to come in this way to process water, its effect is mainly determined by air supporting area, and air supporting area is the biggest, and the area contacted with impurities in water is the biggest, and its treatment effect is the best.And existing dissolved gas floatator, the most still have greatly improved space.
Utility model content
The deficiency existed for prior art, the purpose of this utility model is to provide a kind of air flotation effect more preferably dissolved gas floatator.
For achieving the above object, this utility model provides following technical scheme: a kind of high-efficiency dissolued-air air floatation machine, including water inlet, outlet, shell and high pressure inflator, the outlet side of described high pressure inflator is provided with the first cutting net and the second cutting net, the mesh size of described first cutting net and the second cutting net is micron order, the mesh size of described second cutting net is additionally provided with high performance airscrew less than the mesh size of the first cutting net, the rear end of described second cutting net.
This utility model is further arranged to: described enclosure is additionally provided with an agitation propeller, and described agitation propeller is arranged at the interior side away from high performance airscrew of shell, and the described horizontal level of agitation propeller is correspondingly arranged with the horizontal level of high performance airscrew.
This utility model is further arranged to: the surface configuration of described high performance airscrew has some projections and through hole.
This utility model is further arranged to: described enclosure has also been horizontally disposed with a filter screen, and the level height that described filter screen is arranged is higher than outlet.
This utility model is further arranged to: the mesh gap of described first cutting net is 10 microns, and the mesh gap of described second cutting net is 5 microns.
By using technique scheme, high pressure inflator is again to dissolved gas floatator inner inflatable when, first pass through the first cutting net that outlet port is arranged, under the dissection of the first cutting net, bubble is divided into the diameter of 10 micron levels, the most again by the second cutting net, its diameter is reduced further, control in 5 micron levels, and again through high performance airscrew, bubble is smashed the most again, bubble diameter when making to actually enter dissolved gas floatator internal work is the least, which adds whole pneumatically supported effective area, thus improve the work efficiency of dissolved gas floatator.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model a kind of high-efficiency dissolued-air air floatation machine embodiment.
In figure: 1, shell；2, water inlet；3, high pressure inflator；4, outlet；5, the first cutting net；6, the second cutting net；7, high performance airscrew；8, agitation propeller；9, filter screen.
Detailed description of the invention
With reference to Fig. 1, this utility model one high-efficiency dissolued-air air floatation machine embodiment is described further.
A kind of high-efficiency dissolued-air air floatation machine as shown in Figure 1, including shell 1, this shell 1 is cubic.And it is provided above a water inlet 2 at shell 1, is provided with an outlet 4 in its lower end.Inside left at shell 1 is provided with high pressure inflator 3, this high pressure inflator 3 can be to dissolved gas floatator inner inflatable, and at this inflation inlet, first cutting net 5 and the second cutting net 6 is installed, the mesh gap of the first cutting net 5 is set to 10 microns, and the mesh gap of the second cutting net 6 is set to 5 microns.So pressure-air is when entering dissolved gas floatator, and the diameter of its bubble is just controlled in less than 5 microns.And by the high performance airscrew 7 installed in the second cutting net 6 rear end, further bubble is played the effect smashed, thus improves effective air supporting area, reach more efficient effect.In the present embodiment, the surface of high performance airscrew 7 offers some through holes, is also equipped with some projections, such setting simultaneously, it is possible to allow high performance airscrew 7 to smash effect the most outstanding.
In the present embodiment, shell 1 inner right side is provided with an agitation propeller 8, and the position that this agitation propeller 8 is arranged is corresponding with the position that high performance airscrew 7 is arranged, and highly consistent, align in left and right.Liquid within dissolved gas floatator is just stirred by so this agitation propeller 8, and the agitation of this spiral, make the center being gathered in rotation that the impurity in liquid is relative due to the effect of coriolis force, and this position is precisely pressure-air and enters the position of dissolved gas floatator.Thus be equivalent to before the process of air supporting method remove impurity many one by the process of refuse collecting, thus improve the efficiency of whole remove impurity.And being internally provided with a filter screen 9 at dissolved gas floatator, filter screen 9 is horizontally disposed with, and its area is identical with the floor space within dissolved gas floatator, and the level height that arranges of this filter screen 9 is higher than the height of outlet 4.So, some bigger impurity, it becomes possible to filtered by this filter screen 9, will not flow out from outlet 4.
The above is preferred implementation of the present utility model, to those skilled in the art without departing from this utility model principle on the premise of, it is also possible to making some modification and improvement, these also should be regarded as the protection domain of utility model.
