Description
Technical field
The utility model belongs to technical field of sewage treatment equipment, specifically relates to a kind of air floatation machine.
Background technology
Along with socioeconomic high speed development, living standards of the people improve constantly, town and country water consumption increases gradually, and pollute more and more serious, the former algae class of Water purification gets more and more, removing the most effective way of algae is exactly air supporting, its principle of air floatation machine manages to make to produce a large amount of microbubbles in water, to form water, gas, and be removed the three-phase mixture of material, in interfacial tension, under the acting in conjunction of the many kinds of forces such as bubble rising buoyancy and hydrostaticpressure difference, promote that micro bubble sticks to after in removed tiny oil droplets, the water surface is floated to because adherend density is less than water, thus make the suspended substance in water, the separated removal such as elaioleucite.But the dissolving air flow of existing air floatation machine is uncontrollable, causes the molten tolerance in dissolving too much or too low, have impact on the generation of bubble, and then have impact on air flotation effect, thus reduce wastewater purifying efficiency; In addition, existing air-floating apparatus is provided with the equipment such as pressurized vessel, air compressor machine, recycle pump, and thus facility investment is large, occupation of land is large, it is loaded down with trivial details to safeguard, noise large, management inconvenient.
Utility model content
For above-mentioned weak point of the prior art, the purpose of this utility model is intended to provide a kind of compared with conventional pressure air floatation machine, and have more processing property and stablize, operational management is easy, facility compact, the air floatation machine that noise is little.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of air floatation machine, it comprises pond body and multiphase flow pump, described pond body is divided into zone of action and disengaging zone, the top of zone of action is provided with connected entrance, zone of action is communicated with by connected entrance with disengaging zone, body the connect position of contact area one end in pond is also provided with bubble mud sump and clean water basin, pond body is provided with material inlet pipe and rising pipe, the feed end of material inlet pipe is connected with zone of action, and the feed-water end of rising pipe is connected with clean water basin; Inside, zone of action is provided with screw feeder, and described screw feeder is provided with production well, and disengaging zone and bubble mud sump contact site are provided with connected entrance, and bubble mud sump and clean water basin contact site are provided with filter screen; Multiphase flow pump is provided with water inlet pipe, filling pipe, inlet pipe and dissolved air water pipe, the feed-water end of filling pipe is connected with rising pipe, the outlet side of inlet pipe is connected with filling pipe, and the water side of dissolved air water pipe is connected with disengaging zone, and described dissolved air water pipe is provided with reducing valve.
The setting of reducing valve ensure that and improves dissolved-air rate and outgassing rate by the low pressure operation of dissolved air water pipe.
During work, sucked together by G&W through high-pressure pump import, the impeller meet through pump becomes tiny dissolved air water, then is released into milky dissolved air water through reducing valve, the coagulated particles of inside, disengaging zone is floated, thus reaches the object of purification.Multiphase flow pump can replace force (forcing) pump, air compressor machine, large-scale dissolving, ejector and discharge first-class, saves facility investment and energy consumption.
Preferably, the upper end of described screw feeder is provided with power set, and the connecting portion of power set and screw feeder is provided with inlet mouth, and production well is arranged on the blade of screw feeder uniformly.Screw feeder setting out pore is to be in suspended state all the time when making material enter zone of action, ensure that air flotation effect after the material being in suspended state enters disengaging zone.
Preferably, be inclined upwardly near bubble mud sump side at the bottom of the pond of described disengaging zone, bottom disengaging zone, be provided with some sludge out pipe.Be inclined upwardly at the bottom of the pond of disengaging zone, under the effect of dissolved air water, the current of inside, disengaging zone, to the motion of bubble mud sump direction, guarantee that coagulated particles with the fastest speed along with current enter bubble mud sump, can improve the working efficiency of air floatation machine.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
