Description
Technical field
The present invention relates to washing machine field, specifically dry cleaner, the oil-water separation side of a kind of Domestic dry washing machine
Method and oily-water seperating equipment.
Background technology
The dry cleaner that medicated clothing is carried out by existing use DC naphtha includes: DC naphtha case, DC naphtha pump,
Cleaning-drum, fluid reservoir, fan, heater, condenser, distillator, oil water separator, vacuum pump etc..Its
Dry cleaning processes is substantially: the DC naphtha in DC naphtha case through pipeline in pump enters cleaning-drum, it is achieved dry-cleaning
The feed liquor washing of solvent, after washing, dries de-liquid, and DC naphtha is through flowing to fluid reservoir, it is achieved DC naphtha
Separate with clothes.During drying, fan work, cold wind becomes hot-air through heat pump heating and enters in cylinder,
DC naphtha steam is taken away by hot blast by leakage fluid dram, enters air duct, and vapours, after heat pump, cools down
Generate mixed with water, the oil water mixture of liquid by DC naphtha.
The DC naphtha cost of existing dry cleaner is higher, itself also has certain contaminative, so, in dry-cleaning
Machine uses after medicated clothing has been carried out by DC naphtha, need the DC naphtha in oil water mixture is separated,
Reclaim, to reduce the washing cost of user, to reduce the pollution to environment.
Traditional structure of oil water separator is very simple, and workflow is: mixing liquid flows into oil-water separation from pipeline
Device, it is DC naphtha that oil can automatically be divided into upper and lower two-layer, upper strata with water because density is different, and lower floor is water, works as liquid
When body is abundant, the DC naphtha liquid on upper strata can be crossed the dividing plate of oil water separator and enter pipeline, arranges along pipeline
Enter reserving liquid tank.And the water of lower floor can be drained along pipeline under the conditions of liquid structure is rational.Such structure due to
The difference of oil-water ratio is it is difficult to ensure that the height in separatory face, when separatory face is the highest or the lowest it is difficult to ensure that the essence separated
Degree, and when oil-water ratio close to time, due to separating and high close to can be difficulty with completing at short notice of density
The separation of precision, and then the normal effect of oil water separator cannot be ensured.
The oily water separation technique of dry cleaner utilizes, through consulting Patents document, such as Application No.
A kind of oily-water seperating equipment of Chinese patent of 201220188248.1 and use the dry cleaner of this device, wherein profit divides
Have the housing surrounding cavity from device, described housing is communicated with the feed tube for mixing liquid entrance, for arranging
The drain pipe of water and the drain pipe flowed out for solvent, arrange drain solenoid valve, at described sky on described drain pipe
Intracavity is provided with the liquid level sensor for detecting liquid height, described liquid level sensor and drain solenoid valve and control
Device connects.This utility model simple in construction, for the profit of relatively difficult separation, especially for ratio close to 1
Profit, has the highest separation accuracy, and then ensure that the normal work of dry cleaner.
But, the liquid level sensor used by oily-water seperating equipment in such scheme is the pressure biography that prior art is conventional
Sensor, uses this kind of sensor can only control oil water separation process by measuring the liquid level in oily-water seperating equipment,
The precision making oil-water separation is poor, and oil-water separation can not get being obviously improved.Meanwhile, profit in such scheme
Segregation apparatus is provided with two chambers, adds the complexity of oily-water seperating equipment, does not the most introduce and how to use liquid
Oily-water seperating equipment is controlled by level sensor.
In view of this special proposition present invention.
