Description

Oil-water separator

Technical Field

The invention belongs to the field of waste oil recovery devices, and particularly relates to an oil-water separator.

Background

When the numerical control cutting machine works, on one hand, a moving part needs to be automatically lubricated, and on the other hand, cutting fluid needs to be automatically poured. The motion structure of the numerical control machine determines that a lubricating system of the numerical control machine is open lubrication, namely lubricating oil (mineral oil) is sprayed on the surface of a motion part, the motion part slides mutually to form a lubricating oil film, and the mutual motion inevitably consumes the lubricating oil and continuously generates waste oil to flow out. In metal cutting systems, a large amount of cutting fluid (emulsion-the main component is water-based) is continuously poured, and the cutting fluid is necessarily recycled.

The storage emulsion that adopts to set up in the digit control machine tool bottom to have the storage water tank to retrieve storage in the storage water tank cutting fluid includes the waste oil that the lubrication produced, and the profit mixes together, leads to two consequences easily: firstly, easily make the emulsion produce the phase transition and influenced the machinability, secondly too much oil floats and makes the emulsion isolated air promote anaerobic reaction on the cutting fluid upper strata, produces the foul smell and has polluted the environment. At present, mechanical oil skimming modes such as a sponge oil skimmer and the like are mainly adopted, and the methods have the defects of low reliability, incomplete skimming, short service life, large occupied space and the like.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The following detailed description of the principles of the invention is provided in connection with the accompanying drawings.

The invention designs an oil-water separator suspended in an emulsion system to be separated, which mainly comprises an oil guide pipe unit and a buoyancy adjusting mechanism which are connected with each other, wherein the buoyancy adjusting mechanism is used for adjusting the depth position of the most appropriate oil collecting layer of the inlet end of the oil guide pipe unit which is submerged in the oil layer. Experiments show that when the liquid level of the waste oil port is submerged to 1-2mm, the oil layer collecting effect is optimal, so that the position of the waste oil port submerged to 1-2mm below the liquid level is adjusted in the specific implementation process of the device.

In a specific embodiment of the device designed by the present invention as shown in fig. 1-2, the buoyancy adjusting mechanism comprises a float unit and a balance cylinder 3, and further comprises a height adjusting mechanism, the float unit and the balance cylinder 3 are connected to the height adjusting mechanism, and the proportional relationship of the volumes of oil layers discharged by the float unit and the balance cylinder 3 is adjusted by adjusting the height adjusting mechanism, so as to adjust the depth position of the inlet end of the oil conduit unit submerged into the oil layer.
