Referring to Fig. 1, the utility model proposes steel rolling oil removing hydrolysis device, in actual job, its tool
Body running process is as follows：
After sewage enters water inlet 141 of the oil removal case 1 by exterior tubing 31, first in the sludge settling area
Flowed downward in 101, and flowed to the upside of the oil removal filtering area 102 through the runner 100 on the downside of the settling baffle 1a,
In the presence of first inclined plate packing 11, sewage can occur mud-water separation, on the one hand, the larger sludge of density is in Action of Gravity Field
It is lowered into sludge bucket 16, the partial sludge is discharged outside oil separation equipment by the presence of sludge screw pump 17, it is on the other hand, dirty
Oil in water is relatively low due to density, in the uphill process for passing through first inclined plate packing 11 with sewage, is separated with sewage
And float on sewage upper strata, and then, the oil slick in the oil removal filtering area 102 and floating oil collecting area 103, along the flowing side of sewage
To, can be automatically or in the presence of the scraper plate that chain-type scrapes slag Oil scraper 10 be moved horizontally, floating in inflow floating oil collecting area 103
In oil groove 12, the oil slick in sewage is collected for the first time, and periodically extracted out oil removal by being arranged on the oil pump 18 outside oil removal case 1
Equipment, and enter in sludge storage tank 19；
Afterwards, sewage flows downward along the floating oil collecting area 103, and through the oblique ripple filler 13 on the downside of oil slick baffle plate 1c
When, form large volume of oil after can the original scattered little particle oil droplet of little particle oil droplet coalescence, i.e. sewage be gathered
Drop, bigger oil droplet has stronger buoyancy, and the lighter sump oil of formation is upward in collection oil collection area 104 in the presence of buoyancy
Motion, until water surface is floated up to, from flowing into the oil slick groove 12 at the collection oil baffle 1d for being arranged on pond body upper end, the part
Oil slick periodically extracts oil separation equipment out by oil pump 18, collects in sludge storage tank 19；
Sewage after secondary oil removing, flows up in the settler overflow area 105, when its liquid level is higher than the overflow
During weir plate 15, sewage flows into blowdown area 106, and the water distribution of the hydrolytic tank 2 is flow to through oil removal case delivery port 142 and pipeline 143
In device 21, sewage exports 212 in the water dispensing apparatus 21 by each, is divided into some tributaries, and each tributary enters one
, with water tube hose 23, from top to bottom with the internal flow of water tube hose 23, sewage is through water-locator 24 for sewage in the presence of pressure difference for root
The bottom of pond of hydrolytic tank 2 is injected, and is flowed from bottom to top in the hydrolytic tank 2, when sewage passes through second inclined plate packing 22
When, when mud-water separation, i.e. water containing dirt is flowed upwardly through the second inclined plate packing 22, clear liquid continues up flowing, and sludge is intercepted
And sink, sludge blanket is formed between bottom of pond and the second inclined plate packing 22, wherein, with the increase of sludge quantity, newborn sludge
Due to more open, density is lighter, is moved from bottom to top with ascending current, after being enriched with the presence of the second inclined plate packing 22 under
It is heavy, the organic matter in sewage is degraded in the sludge suspension region of the downside of the second inclined plate packing 22, and deposit in advance
With aging, the current that density increase can not be raised hold up and sink to bottom of pond sludge, and by being arranged on the discharge pipeline 2.5 of bottom of pond
Discharged by external dirty mud pipeline or sludge pump.
In the utility model, by setting oil separation equipment and hydrolytic tank, the sludge of sewage and oil slick can be removed, behaviour
Make easy, improve wastewater biodegradability and stable water outlet, reduce operating load, it is simple and feasible；Due to using integration
Structure, saves and takes up an area and invest, and overcomes that prior art processes are complicated, it is high to take up an area big, investment and operational reliability is not strong asks
Topic.
The schematical specific embodiment of the utility model is the foregoing is only, model of the present utility model is not limited to
Enclose.Any those skilled in the art, the done equivalent change on the premise of design of the present utility model and principle is not departed from
Change and change, the scope of the utility model protection all should be belonged to.
