Oil-water separator

Abstract

The invention discloses an oil-water separator which comprises an oil guide pipe unit and a buoyancy adjusting mechanism which are connected with each other, and the buoyancy adjusting mechanism adjusts the depth position of the inlet end, immersed in an oil layer, of the oil guide pipe unit. According to the separator designed by the invention, the relative height of a float bowl can be conveniently changed by adjusting the buoyancy adjusting mechanism, and the inlet end of the oil guide pipe unit for collecting waste oil is positioned at the optimal depth position, so that the influence of the height change of emulsified liquid on the position of the inlet end is avoided.

Description

technical field [0001] The invention belongs to the field of waste oil recovery devices, and in particular relates to an oil-water separator. Background technique [0002] CNC cutting machine tools need to automatically lubricate moving parts while working, and need to automatically pour cutting fluid on the other hand. The motion structure of CNC machine tools determines that its lubrication system is open lubrication, that is, lubricating oil (mineral oil) is sprayed onto the surface of moving parts, and the moving parts slide against each other to form a lubricating oil film. This mutual movement will inevitably consume lubricating oil continuously and generate Oil is flowing out. In the metal cutting system, a large amount of cutting fluid (emulsion - the main component is water-based) is continuously poured, and these cutting fluids must be recycled. [0003] In the prior art, a water storage tank installed at the bottom of the CNC machine tool is used to recover the ...

Problems solved by technology

[0003] In the prior art, a water storage tank installed at the bottom of the CNC machine tool is used to recover the cutting fluid. The emulsion stored in the water storage tank includes the waste oil generated by lubrication, and the oil and water are mixed together, which easily leads to two consequences: one is easy to emulsify The phase change of the cutting fluid affects the machinability. The second is that too much oil floats on the upper layer of the cutting fluid, which isolates the emulsion from the air and promotes anaerobic reaction, which produces foul odor and pollutes the environment.

At present, the methods mainly adopt mechanical oil skimming methods such as sponge oil skimmers. These methods have disadvantages such as low reliability, unclean skimming, short life, and large space occupation.
