Description
Technical field
The utility model belongs to environmentally friendly technical field of water treatment equipment, and in particular to a kind of cavitation air flotation settler.
Background technology
Cavitation air flotation settler is a kind of by chemical flocculation, flotation settling system, so as to carry out solid-liquid point to sewage
From a kind of device systems.
According to the applicant understood, common Eddy concave air-floatation apparatus relies primarily on air supporting floatation and carries out separation of solid and liquid, in water
The polluter for being adapted to air supporting flotation flocculates agglomerating by dosing, and under the rolling action of bubble, floating to the water surface, by scraping slag
System is blown off；Sediment is using coprecipitation modes such as inclined tubes.When existing suspension has sediment again in running into water, two methods string
Connection is used, and such both of which needs dosing and provides hydrodynamic force, not only poor processing effect, and floor space is big, and in operation
When increase investment and operating cost, cause the wasting of resources.
Utility model content
Technical problem to be solved in the utility model is to overcome the shortcoming of prior art heavy there is provided a kind of cavitation air flotation
Shallow lake device, realizes air supporting and the blowdown simultaneously of natural subsidence two ways, has the advantages that scavenging effect is good, save equipment cost.
In order to solve the above technical problems, a kind of cavitation air flotation settler of the utility model offer, including flocculation system,
Aerating system, scrape slag system and reaction system, flocculation system is installed in one end of reaction system, reaction system close to flocculation system
Aerating system is installed at unified end, and reaction system is from top to bottom followed successively by flotation area, mixed zone and settling zone, the stirring of flocculation system
Device is extended in mixed zone bottom, is scraped slag system and is installed on flotation upper end, settling zone is connected with bucket.
By the flocculation of flocculant in flocculation system, enter the bulk that the pollutant in sewage flocculates into bulky grain
Subsequent reactions system, wherein the uniform micro-bubble that the cluster of grains for being adapted to air supporting flotation is produced by aerating system is carried to water
More than face, scraped by scraping slag system to slag case progress dewater treatment；Another part is adapted to the material of coagulating sedimentation by sinking naturally
It is down in bucket and periodically carries out dewater treatment.
The technical scheme that the utility model is further limited is：Scraping slag system includes Slag Scraping Device, conveyor screw and reductor,
Slag Scraping Device and conveyor screw are connected by belt with the rotating shaft of reductor respectively.
Further, Slag Scraping Device includes scum board and scrapes slag chain, and scum board, which is fixed on, to be scraped on slag chain, is scraped slag chain and is nibbled
That closes connection Slag Scraping Device two ends turns tooth.
Further, scrape slag chain and scrape slag chain for nylon, scum board is rubber scum board.
Further, aerating system is CAF type cavitation aerators.
Further, slag system connection drainage arrangement is scraped.
The beneficial effects of the utility model are：The device is skillfully constructed, it is simple in construction, be easily installed, will be polluted in sewage
After thing flocculation, the bulk pollutant of bulky grain is settled down to bucket, and the cluster of grains for being adapted to air supporting flotation is produced by aerating system
Uniform micro-bubble carry to the water surface, scraped by scraping slag system to slag case, realize that air supporting and natural subsidence two ways are same
When blowdown, have the advantages that scavenging effect is good.Scrape slag system and scrape slag chain and rubber scum board from nylon material, alleviate and set
It is small that standby weight saves cost, running noises.
