Abstract

The invention provides a method for prolonging the service life of a cleaning waste liquid. The method is characterized in that a density difference between oil and a liquid in a cleaning waste liquid tank is used, oil is an upper layer, an overflow hole is arranged on a tank body, the upper layer oil flows through the oil overflow hole and flows into an oil-liquid separator, the content of oil and the content of the liquid in the oil-liquid separator are high and low respectively, oil flows into a waste oil collecting box from a separation hole above the tank body of the oil-liquid separator after stationary layering, the lower layer liquid is sucked into a liquid storage tank through a pump and is precisely filtered by active carbon, and the filtered liquid is reused in the cleaning waste liquid tank, and has a liquid level supplementing effect. When the tank liquid does not work, the tank liquid obtained after the flow of the oil surface through the overflow hole is filtered by an active carbon precision filter to carry out self-circulation in order to realize a maintenance effect. The method has the advantages: the above design maintains the tank liquid of the cleaning waste liquid tank clean and makes waste oil recovered; and the production cost is reduced, the emission of pollutants is reduced, and economy and environmental protection are realized.

Description

Extend the waste liquid method in service life of cleaning
(1) technical field
The present invention relates to a kind of waste liquid method in service life of cleaning that extends.
(2) background technology
For the produced product of press industry, some surface and oil contaminant is heavier, client does not approve, greasy dirt will clean in stamping parts manufacturer, can use a large amount of cleaning agents, virtually increased processing cost, product greasy dirt own greatly very easily makes cleaning agent lose efficacy and discards, and the present invention has designed a kind of waste liquid method in service life of cleaning that extends.
  
(3) summary of the invention
The object of the invention is to design a kind of waste liquid method in service life of cleaning that extends.It will clean reuse after effluent purifying, will after waste oil collecting, can take out simultaneously.
Technical scheme of the present invention: a kind of waste liquid method in service life of cleaning that extends, it is characterized in that utilizing the density contrast that cleans the fluid in waste liquid tank, oil is on upper strata, by open an overfall above cell body, upper strata oil is flowed into after oil-liquid separator along overfall, now oily many liquid is few, after static layering, oil flows into waste oil collecting case by the separating opening of the cell body top of oil-liquid separator, subnatant is by pump suction liquid deposit groove, after filtering by active carbon is accurate, be back to use cleaning waste liquid tank, play the effect that supplements liquid level simultaneously.In the time that tank liquor is not worked, the accurate filter of tank liquor active carbon after pasta flows out by overfall filters self-loopa and plays maintenance effect in addition.
Superiority of the present invention: by the present invention, make the tank liquor that cleans waste liquid tank keep clean, also waste oil is reclaimed simultaneously.Not only reduce production cost, reduced the discharge of pollutant simultaneously, not only economy but also environmental protection.
(4) brief description of the drawings
Accompanying drawing 1 is structural representation of the present invention,
Wherein: the 1st, clean waste liquid tank, the 2nd, tube connector, the 3rd, oil-liquid separator, the 4th, liquid deposit groove, the 5th, valve one, the 6th, valve two, the 7th, the accurate filter, the 8th of active carbon, drain pipe, the 9th, feed tube, the 10th, waste oil collecting case, the 11st, overfall, the 12nd, inlet tube, the 31st, separating opening, the 32nd, pump, the 33rd, bracing frame, the 34th, cell body.
(5) detailed description of the invention
As accompanying drawing 1 shows: a kind of waste liquid method in service life of cleaning that extends, it is characterized in that utilizing the density contrast that cleans the fluid in waste liquid tank 1, oil is on upper strata, by open overfall 11 above cell body, upper strata oil is flowed into after oil-liquid separator 3 along overfall 11, now oily many liquid is few, after static layering, oil flows into waste oil collecting case 10 by the separating opening 31 of cell body 34 tops of oil-liquid separator 3, subnatant is by pump 32 suction liquid deposit grooves 4, after filtering 7 by active carbon is accurate, be back to use and clean waste liquid tank 1, play the effect that supplements liquid level simultaneously.In the time that tank liquor is not worked, accurate filter 3 filtrations of tank liquor active carbon after pasta flows out by overfall 11 are carried out self-loopa and are safeguarded tank liquor in addition.
Concrete enforcement: the upper strata oil slick that cleans waste liquid tank 1 flows into oil-liquid separator 3 through overfall 11, bottom is cleaned waste liquid suction liquid deposit pond 4 by pump 32 by oil-liquid separator 3, by the separating opening 31 on the cell body 34 of oil-liquid separator 3, waste oil flowed into waste oil collecting case and collect 10.When the accurate filter 7 of active carbon is flat, valve 1 is closed, valve 26 is opened, and cleans the self-loopa of 1 li of tank liquor of waste liquid tank and filters, in the time that tank liquor face will supplement, open valve 1, valve-off 26, liquid is laid in to the liquid suction of groove 4 and cleaned waste liquid tank 1, supplement liquid level.

Claims (1)

1. one kind extends the waste liquid method in service life of cleaning, it is characterized in that utilizing the density contrast that cleans the fluid in waste liquid tank, oil is on upper strata, by open an overfall above cell body, upper strata oil is flowed into after oil-liquid separator along overfall, now oily many liquid is few, after static layering, oil flows into waste oil collecting case by the separating opening of the cell body top of oil-liquid separator, subnatant is by pump suction liquid deposit groove, after filtering by active carbon is accurate, be back to use cleaning waste liquid tank, play the effect that supplements liquid level simultaneously, in addition in the time that tank liquor is not worked, the accurate filter of tank liquor active carbon after pasta flows out by overfall filters self-loopa and plays maintenance effect.
