The casting mold-releasing agent purifying box
Technical field
The utility model relates to water or technical field of waste water processing, is specially a kind of oily water separation oil trap of simple and convenient, relates in particular to the purification of casting mold-releasing agent.
Background technology
Oil trap is to utilize the difference of specific gravity of oil and water, separates a kind of processing structures of removing the suspension oil that in sewage, particle is larger.The waste water containing a large amount of oil products is discharged in petroleum industry and petrochemical industry in process of production; The coking of coal and gasified industry are discharged the waste water containing high density tar; The waste water that the discharge such as woolen industry and meat industry contains more grease.These oily(waste)waters can pollute as entered water body, and soil pores can be stopped up in irrigated farmland, harmful plant growth.Recycled as the oil product in waste water, not only can be avoided the pollution to environment, can be obtained considerable economic return again.The multiplex Steel Concrete of oil trap is built, and also useful masonry is built by laying bricks or stones, adopts underground or semi-underground form, and volume weighs greatly, can not efficiently complete the removing oil slick.
Summary of the invention
Goal of the invention of the present utility model is in order to overcome the shortcoming of above-mentioned background technology, and a kind of volume that can reduce oil trap is provided, and improves the casting mold-releasing agent purifying box of the efficiency of oil trap oil removing.
The technical solution of the utility model is: a kind of casting mold-releasing agent purifying box, it comprises casing, described box house is become " product " font by baffle for separating, three parts are treating pond, secondary purification pond and the clean liquid pool communicated, described treating pond is positioned at clean liquid pool top, and the secondary purification pond is positioned at clean liquid pool right side; In the left part of described treating pond, antetheca is provided with strumbox, and sewage flows into from the upper side, and the treating pond middle part is fixed with type sloping plate component, and upper end, rear wall middle part is provided with oil outlet, and the right part lower end is provided with communicating pipe; Inner upper left side, described secondary purification pond is provided with Labyrinth box, and left and right, secondary purification pond two walls are provided with for placing the supporting plate of oil header, and the oil header inner and upper is provided with liquid level alarming switch, and Zuo Bi lower end, secondary purification pond is provided with the communicating pipe with clean liquid pool; Be provided with float switch in described clean liquid pool and be connected with water pump.
Described liquid level alarming switch is comprised of ball float and ball float warning howler.
The beneficial effects of the utility model are: the unpowered oil removing of the utility model, and oil removal rate is greater than 90%, the clean liquid recycle after processing; Without consumptive material, energy-conserving and environment-protective, safeguard simple; Floor space is little, when the processing water yield is identical, accounts for the 1/4-1/3 of parallel flow intercepter.

Fig. 1 is this utility structure schematic diagram;
Wherein: 1, casing, 2, treating pond, 3, strumbox, 4, type sloping plate component, 5, dividing plate, 6, communicating pipe, 7, Labyrinth box, 8, the ball float warning howler, 9, oil header, 10, the secondary purification pond, 11, dividing plate, 12 communicating pipe, 13, float switch, 14, clean liquid pool.
Embodiment
The present embodiment is a kind of casting mold-releasing agent purifying box, it comprises casing 1, described casing 1 inside is separated into " product " font by dividing plate 5 and dividing plate 11, three parts are treating pond 2, secondary purification pond 10 and the clean liquid pool 14 communicated, described treating pond 2 is positioned at clean liquid pool 1 top, and secondary purification pond 10 is positioned at clean liquid pool 14 right sides; In the left part of described treating pond 2, antetheca is provided with strumbox 3, sewage flows into from the upper side, treating pond 2 middle parts are fixed with type sloping plate component 4, flow velocity has been slowed down in the pond that type sloping plate component 4 is separated into several connections to treating pond 2, improved deoiling effect, the upper end, rear wall middle part for the treatment of pond 2 is provided with oil outlet, and the right part lower end is provided with communicating pipe 6; 10 inner upper left sides, described secondary purification pond are provided with Labyrinth box 7, secondary purification pond 10 left and right two walls are provided with for placing the supporting plate of oil header 9, it is ball float warning howler 8 that oil header 9 inner and upper are provided with liquid level alarming switch, oil header 9 is collected the oil of separation from Labyrinth box 7, and 10Zuo Bi lower end, secondary purification pond is provided with the communicating pipe 12 be connected with clean liquid pool 14; Be provided with float switch 13 in described clean liquid pool 14 and be connected with water pump.
During concrete the use, soiling solution enters strumbox 3, and the macrobead greasy dirt is filtered out and is deposited in the first lattice, and filtrate is overflowed strumbox 3 after precipitating in the second lattice; Then the obstruct due to first type sloping plate component 4 precipitates again, the oil slick on surface one deck from breach flows into is blocked by second type sloping plate component 4, oil slick flows out and enters Labyrinth box 7 from oil outlet, in Labyrinth box 7, again divides oil the rear oil header 9 that flows into, and the gap at the bottom of clean liquid slave plate flows into lower one deck; Process before repeating between the third and fourth swash plate, clean liquid just flows into secondary purification pond 10, and in secondary purification pond 10, precipitation, finally just flow into clean liquid pool 14, and the water pump of being controlled by float switch 13 is taken away.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation on its shape or structure; every have identical with a application or akin technical scheme, within all dropping on protection domain of the present utility model.
