Claims

[Scope of Claim for Utility Model Registration] An oil purification device for regenerating waste oil containing water and dirt, etc., which (1) uses an oil supply pipe or the like having a large number of pores inside the oil purification device; The above-mentioned water removal piping route includes a decompression tank, temperature raising equipment, and circulation pump that ejects oil and is equipped with moisture evaporation promoting means such as a multistage flow-down shelf, and a fine dust removal piping route that includes an electrostatic oil purifier. An oil purification device characterized by being provided with. (2) In the oil circulation piping route of the oil purifier, there is a primary waste oil supply piping that removes coarse particles and metal powder in advance, and an oil circulation 2 that removes fine water and fine dust.
It consists of a secondary piping system and a tertiary piping for taking out purified oil, and a transmission type oil purity level sensor using a photoconductive cell is installed in the secondary piping system on the inlet side of the decompression tank (processing tank). Therefore, water emulsion and fine dust contamination are continuously detected, and a directional solenoid valve installed in the piping system is operated based on a preset cleanliness value to automatically perform a predetermined cleaning process. An oil purification device characterized by regenerating clean oil.
