1. A waste oil purification apparatus, comprising:
a purifier configured to primarily purify waste oil via a purification method through vacuum and multi-stage filtering; and
a separator configured to secondarily separate and remove foreign materials contained in the waste oil purified by the purifier;
wherein the purifier comprises:
a first inflow line and a second discharge line configured to introduce or discharge waste oil;
a purification chamber configured such that filtering of waste oil is performed while the waste oil is introduced and discharged by vacuum suction of a suction pump; and
a plurality of filter units disposed inside the purification chamber, and configured to remove foreign materials in passing waste oil;
wherein the separator comprises:
a second inflow line and a second discharge line configured to introduce or discharge waste oil;
a separator chamber configured to secondarily separate waste oil and foreign materials;
a waste oil discharge line disposed in a lower end portion of the separator chamber, and configured to discharge waste oil, transferred from the purifier, upward within the separator chamber; and
a plurality of magnetic filter units disposed adjacent to an upper end of the waste oil discharge line, spaced apart from each other at regular intervals, and configured to remove metallic foreign materials in waste oil, discharged upward by the waste oil discharge line, by means of magnetic force;
wherein the purification chamber of the purifier comprises:
a pair of longitudinal partition walls formed in longitudinal directions, and configured to separate filtering spaces and bypass spaces;
a plurality of transverse partition walls disposed on outsides of the longitudinal partition walls in transverse directions, and configured to form partitions between the bypass spaces; and
a plurality of installation guide portions disposed to allow each pair of installation guide portions to face each other at regular intervals on insides of the longitudinal partition walls, and configured to guide the filter units through their installation; and
wherein the separator further comprises:
a bubble generator configured to add micro-bubbles to waste oil pumped from the separator chamber by a pump; and
a discharge pipe configured to discharge the waste oil, to which the micro-bubbles have been added, to the separator chamber, wherein the discharge pipe extends over top portions of the magnetic filter units, and discharge holes of the discharge pipe are formed downward to face the magnetic filter units.
