Description

Dissolved air flotation device
The utility model relates to sewage disposal device, especially a kind of dissolved air flotation device that is used for the dried up suspended substance of branch, oils, flco.
Dissolved air flotation device is a kind of sewage disposal device that is used for dirts such as the dried up suspended substance of branch, oils, flco.Dissolved air flotation device is widely used in petrochemical industry, papermaking, mechanical workout, textile printing and dyeing, butchers, food-processing and municipal sewage treatment.Traditional dissolved air flotation device exists and takes up an area of greatly, and power consumption is high, the noise height, and cost height and equipment are installed complicated, and molten gas release head easily stops up deficiencies such as maintenance difficult.
The purpose of this utility model is to exist at traditional dissolved air flotation device to take up an area of greatly, power consumption is high, noise height, cost height, and equipment is installed complicated, molten gas discharges head and easily stops up, and the problem of maintenance difficult provides a kind of power consumption few, noise is little, cost is low, and is easy for installation, and molten gas discharges the not susceptible to plugging dissolved air flotation device of head.
Dissolved air flotation device described in the utility model comprises air flotation pool, air dissolved pump, slag scraper, spiral conveyer.The air flotation pool left end is provided with overflow groove.The slag scraper that is made of chain and scraper plate is loaded on the top of air flotation pool.Spiral conveyer is equipped with in the below of slag scraper one end.One end of spiral conveyer links to each other with slag-drip opening.Air dissolved pump is loaded on the outer side-lower of air flotation pool right-hand member.Being positioned at the clear water refluxing opening that the overflow groove bottom has filtering net links to each other with air dissolved pump by reflux line.The molten gas that is positioned at the air flotation pool bottom discharges head and is communicated with air dissolved pump.Molten gas discharges head and is provided with molten gas liberation port.Air flotation pool right-hand member one side is equipped with the sewage import.Clear water output is equipped with in the overflow groove left side of air flotation pool left end.Overflow groove one end of air flotation pool also is provided with baffle plate, has between baffle plate bottom and the air flotation pool bottom and confesses the gap that water is used.
Described air flotation pool also can comprise main air flotation zone and auxilliary air flotation zone, and main air flotation zone is positioned at the right-hand member of air flotation pool.This moment, air dissolved pump was loaded on the outer side-lower of air flotation pool master air flotation zone.The sewage import is loaded on air flotation pool master air flotation zone right side.
The utility model has the advantages that power consumption is few, noise is little, and cost is low, and is easy for installation, and molten gas discharges head and is difficult for stopping up.
Fig. 1 is the front view of the utility model dissolved air flotation device structural representation;
Fig. 2 is the vertical view of Fig. 1.
The utility model is described in further detail below in conjunction with embodiment shown in the drawings:
As shown in Figure 1 and Figure 2, the described dissolved air flotation device of present embodiment comprises air flotation pool 9, air dissolved pump 12, slag scraper 5, spiral conveyer 4.Air flotation pool 9 comprises main air flotation zone 10 and auxilliary air flotation zone 8, and main air flotation zone 10 is positioned at the right-hand member of air flotation pool 9.The left end of air flotation pool 9 is provided with overflow groove 2.The slag scraper 5 that is made of chain 6 and scraper plate 7 is loaded on the top of air flotation pool 9.Spiral conveyer 4 is equipped with in the below of slag scraper 5 ends.One end of spiral conveyer 4 links to each other with slag-drip opening 18.Air dissolved pump 12 is loaded on the outside of the main air flotation zone 10 of air flotation pool 9.Being positioned at the clear water refluxing opening 19 that overflow groove 2 bottoms have filtering net 20 links to each other with air dissolved pump 12 by reflux line 15.The effect of filtering net 19 is to prevent in the particulate matter suction pump.The molten gas that is positioned at main air flotation zone 10 and auxilliary air flotation zone 8 bottoms discharges 14 and is communicated with air dissolved pump 12.Molten gas discharges 14 and is provided with molten gas liberation port 13.Sewage import 11 is equipped with on the right side of air flotation pool 9 main air flotation zones 10.Clear water output 1 is equipped with in the left side of air flotation pool 9 left end overflow grooves 2.Overflow groove 2 one ends of air flotation pool 9 also are provided with baffle plate 17, have between baffle plate 17 bottoms and air flotation pool 9 bottoms and confess the gap 16 that water is used.
During work, air dissolved pump 12 sucks the backflow clear water by filtering net 20, clear water refluxing opening 19 and reflux line 15, sucks air simultaneously, generates saturated dissolved gas water in pump.Saturated dissolved gas water enters in the air flotation pool 9, discharges the part dissolved air water at main air flotation zone 10, and the rest part dissolved air water discharges at auxilliary air flotation zone 8.Dissolved air water produces a large amount of microbubbles after discharging in air flotation pool 9.Sewage enters main floating region 10 by sewage import 11, a large amount of microbubble thorough mixing that produce with dissolved air water in main floating region 10, and in main floating region 10, together float.In the floating-upward process, microbubble climbs up on top of the water suspended substance attached on the suspended substance, and maintains on the water surface under the support of bubble.The microbubble that molten gas liberation port 13 in auxilliary air flotation zone 8 discharges rises, and further keeps the stable of floating on water thing.The suspended substance that is suspended in air flotation pool 9 surfaces is scraped to spiral conveyer 4 by the scraper plate 7 of slag scraper 5, delivers to slag-drip opening 18 by spiral conveyer 4 again and discharges.Gap 16, the overflow port 3 of the clear water of gained between air flotation pool 9 left end baffle plates, 17 bottoms and air flotation pool 9 bottoms enters overflow groove 2 after the sewage disposal, and can be flowed out by clear water output 1.The recirculation water that air dissolved pump 12 sucks is the clear water of air supporting process after handling.
Air dissolved pump 12 in the utility model can be buied by market, and spiral conveyer 4 and the slag scraper 5 that is made of chain 6, scraper plate 7 also are known technology.
