Abstract
The invention discloses a method for separating oil slick of waste cold-rolling fluid. The device for separating oil slick of waste cold-rolling fluid comprises the following parts: 1, an oil discharging pond, 2, an oil discharging hole, 3, a waste oil pond, 4, a fluid outlet tube inlet, 5, a discharging valve, 6, a fluid outlet tube outlet and 7, a waste oil treatment station. In a production process, the cold-rolling fluid loses effect after being used for certain time and is changed; the waste cold-rolling fluid enters the oil discharging pond; the waste cold-rolling fluid in the oil discharging pond is discharged to the waste water treatment station through a pipeline and the discharging valve; when the discharging valve is opened and the liquid surface of the oil discharging pond is higher than the discharging valve, the waste cold-rolling fluid in the oil discharging pond is automatically discharged to the waste water treatment station without power under the action of the gravity force. When the liquid surface is lower than the discharging valve, the discharging is stopped and the oil slick does not flow to the waste cold-rolling fluid pond. The height of the liquid surface of the waste cold-rolling fluid of the oil discharging pond is controlled by the discharging valve, and the size of a discharging valve switch can be adjusted according to the volume of the waste cold-rolling fluid discharged to the oil discharging pond.
Description
Technical field
The present invention relates to the method that a kind of oil slick separates, be applied to Waste Water Treatment, particularly relate to the method that a kind of useless cold rolling liquid floating oil separates.
Background technology
In Industrial processes, cold rolling liquid is a certain proportion of ROLLING OIL, forms emulsion with water through Over emulsfication, plays the cooling and lubricating effect in cold-rolled process.After using the regular hour, the cooling and lubricating effect descends and foreign matter content arrives certain degree, needs the new cold rolling liquid of configuration.Exist two kinds of oil requires to separate in the useless cold rolling liquid that changes, a kind of is to be contained in the water through the ROLLING OIL of emulsification, and this oil utilizes the ramp type water-and-oil separator with the separating of oil waste oil pool that out enters.Another kind is the waste oil that swims in useless cold rolling liquid surface, the dirty oil of separating behind the cold rolling liquid breakdown of emulsion is wherein arranged, also have from hydraulic efficiency oil and the machine oil of hydraulic efficiency system and wheel casing seepage, also mixing some impurity of these excessive fuel consumptions form the liquid of black thickness, have in addition become paste.The dirty oil float of this class is at liquid level, and submerged pump can not be with its suction ramp type water-and-oil separator, in case the separator outage is stopped up in the suction meeting.The difficult problem that to remove these dirty oil always be cold rolling industry.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of effective, easy to operate, useless cold rolling liquid floating oil separation method of need not power, energy-conserving and environment-protective is provided.
Present method solves its technical problem and takes following technical scheme to realize:
The method that useless cold rolling liquid floating oil separates, it is characterized in that being undertaken by following step: 1, structure oil slick separate tank (comprise and unload oil sump, waste oil pool, useless cold rolling liquid pool) 2, useless cold rolling liquid are disposed to and unload oil sump, unload oil sump and are connected with useless cold rolling liquid pool by delivery pipe, bleed valve; 3, unloading oil sump is connected with waste oil pool by outage.In process of production, cold rolling liquid is replaced after using the regular hour to lose efficacy, and useless cold rolling liquid enters and unloads oil sump, and the useless cold rolling liquid that unloads in the oil sump enters useless by pipeline and bleed valve.When bleed valve is opened, be higher than bleed valve when unloading the oil sump liquid level, unload useless cold rolling liquid in the oil sump under action of gravity automatically row advance uselessly, do not need power.Discharging stopped when liquid level was lower than bleed valve, and oil slick can not flow into waste water processing station.Unload the useless cold rolling liquid liquid level of oil sump and controlled by bleed valve, can enter the size that the size of unloading the oil sump amount is adjusted the bleed valve switch according to useless cold rolling liquid.During normal operation, the liquid level of useless cold rolling liquid will be lower than outage all the time, prevents that the liquid level of useless cold rolling liquid is higher than the outage lower-most point, makes useless cold rolling liquid flow into waste oil pool.Along with floating oil layer thickness constantly increases, when the oil slick liquid level was higher than the outage lower-most point, oil slick flowed to waste oil pool.
Beneficial effect of the present invention:
The method that the present invention has adopted a kind of useless cold rolling liquid floating oil to separate, technical process is reasonable, and method is reliable, has solved the difficult problem of cold rolling industry cleaning oil slick; Present method is novel in design, and is easy and simple to handle, separates oil slick effective; Cleaning oil slick process need not power, energy-conserving and environment-protective, and present method has higher promotional value.

Embodiment
In order to explain more fully enforcement of the present invention, provide following processing method embodiment.These embodiments only are to explain rather than limit the scope of the invention.
Embodiment
In process of production, cold rolling liquid is replaced after using the regular hour to lose efficacy, and useless cold rolling liquid enters and unloads oil sump 1, and the useless cold rolling liquid that unloads in the oil sump 1 enters waste water processing station 7 by liquid discharge pipe import 4, bleed valve 5 and liquid discharge pipe outlet 6.When bleed valve 5 is opened, be higher than bleed valve 5 when unloading oil sump 1 liquid level, the useless cold rolling liquid that unloads in the oil sump 1 arranges waste water processing station 7 automatically under action of gravity, do not need power.Discharging stopped when the liquid level that unloads oil sump 1 was lower than bleed valve 5, and oil slick can not flow into waste water processing station 7.Unload the useless cold rolling liquid liquid level of oil sump 1 by bleed valve 5 controls, can enter the size that the size of unloading oil sump 1 amount is adjusted bleed valve 5 switches according to useless cold rolling liquid.During normal operation, the useless cold rolling liquid liquid level that unloads oil sump 1 will be lower than outage 2 all the time, prevents that the liquid level of useless cold rolling liquid is higher than the lower-most point of outage 2, makes useless cold rolling liquid flow into waste oil pool 3.Along with floating oil layer thickness constantly increases, when the oil slick liquid level was higher than the outage lower-most point, oil slick flowed to waste oil pool, and oil slick is separated.This processing method flow process is reasonable, and method is reliable, separates oil slick effective; Cleaning oil slick process need not power, energy-conserving and environment-protective.
