Oil-water separation filter

Abstract

The invention discloses an oil-water separation filter. The oil-water separation filter comprises a liquid inlet, a filter end cover and a filter main shell, wherein the filter end cover is connectedwith the filter main shell; a spiral extrusion structure is arranged in the filter main shell and comprises a fixed plate, a filling material net bag and a movable plate; the filling material net bagis respectively connected with the fixed plate and the movable plate; the other end of the movable plate is connected with a rotating rod which is connected with a motor through an oil seal; and the motor rotates the rotating rod to drive the filling material net bag to rotate and extrude. According to the invention, through arrangement of the spiral extrusion structure in the oil-water separationfilter, automatic extrusion oil discharge of a filling material in the spiral extrusion structure is realized; the service life of the filling material is prolonged; meanwhile, the replacement frequency is reduced; and the cost is reduced.

Description

technical field [0001] The invention relates to oily sewage treatment equipment, in particular to an oil-water separation filter for the treatment of dispersed oily sewage. Background technique [0002] In machinery processing enterprises and cleaning industries, oily sewage often needs to be treated due to the requirements of lubrication and rust prevention. The current methods of treating oily sewage mainly include mechanical grease traps, centrifugation, and other methods. Such treatment methods are inefficient and the accuracy cannot meet the current requirements; while chemical dosing and other methods will destroy some components that need to be reused. Hazardous waste will be generated, and the overall treatment cost is high. [0003] The use of new packing-based degreasers is a current research hotspot. This type of degreaser tries to use coalescence to coalesce oil droplets, let them grow up, and float up to separate them. Commonly used fillers include corrugated...

AI Technical Summary

Problems solved by technology

However, the treatment accuracy of this kind of filler is low, and the treatment effect on dispersed oil is general

One that is emerging now is a coalescing packing with a smaller channel pore size, but one problem that exists is how to discharge the adsorbed oil

At present, the commonly used method is to replace the packing after the adsorption is saturated, which often leads to an increase in the cost of use, and at the same time, the replaced packing becomes hazardous waste.
