Description

Emulsion oil slick separator

Technical field

The utility model belongs to steel rolling mill steel rolling equipment emulsion surface and trade effluent surface sump oil treating apparatus, particularly emulsion oil slick separator.

Background technology

Emulsion system sump oil at China steel rolling mill rolling mill for cold rolled steel strip is handled, the general mechanical type Oil scraper that adopts, its complex structure, the cost height of making and keeping in repair, inconvenient operation, when carrying out the processing of emulsion sump oil, it is poor that contaminated emulsion floating oil layer thickness separates the control effect stability, and the separative efficiency of deposit and suspension is not high.

The utility model content

The purpose of this utility model is to provide a kind of emulsion oil slick separator, it is effective to separate control for contaminated emulsion floating oil layer thickness, handles the separative efficiency height of sediment and suspension, and compact conformation, easy to operate, manufacturing and maintenance cost are low.

The purpose of this utility model is achieved in that a kind of emulsion oil slick separator, the horizontal uniform upright dividing plate that top has the inclined plane that is being provided with in the separator box of cuboid, separator box is separated into the feed liquor case from front to back successively, uniform settling tank and discharge opeing case, wherein path is left in the lower end of first order dividing plate and case bottom surface, the top margin of the upright top board of this dividing plate is concordant with the end face of separator box, all the other dividing plates at different levels are separated into separate settling tank with separator box, the upright top board of this dividing plate has zigzag top margin, and its top margin height reduces successively along parallax, its top of uniform settling tank is installed with the collecting pipe with the adjustable-angle that reclaims mouth and oil drain out respectively, except that first order settling tank, the place ahead of all the other settling tank collecting pipes at different levels is being provided with the diaphragm plate that leaves path at the bottom of bottom and the case, the oil drain out of collecting pipe stretches out outside the separator box, and be connected with the guiding gutter that is provided with on the separator box outer wall, bottom at settling tanks at different levels is installed with blowoff valve respectively, in the bottom of discharge opeing case tapping valve is installed.

The utility model is based on the principle that proportion separates and the oil slick treatment facility that designs, adopted the top of uniform setting to have the upright dividing plate on inclined plane, separator box is separated into the multi stage precipitation case, on the upright top board of the top, inclined plane of dividing plate setting, have zigzag top margin, at the bottom of the place ahead of each settling tank collecting pipe also is being provided with bottom and case, leave the dividing plate of path.Liquid separates at multipole settling tank, in the precipitation process, make proportion be easier to form stable bottom deposit greater than the particle of main body medium, meanwhile, can be by adjusting valve sets for proportion less than the particle and the suspension of main body medium, stablize flow velocity, reduce to separate and disturb, realize fully come-up.Floating layer thickness according to emulsion sump oil supernatant, the angle of regulating collecting pipe realizes, effective separation of oil slick thing, control liquid level by control valve, according to the fluid flow size that enters casing, control liquid level flowing velocity, reduce the interference in the separation process of oil slick layer, help efficient separation, meanwhile, this valve group can realize regular desilting and discharging to the solids precipitation thing of bottom.Therefore, it is effective that the utility model separates control for contaminated emulsion floating oil layer thickness, handles the separative efficiency height of sediment and suspension, and compact conformation, and easy to operate, manufacturing and maintenance cost are low.
