Abstract

The invention discloses a waste oil filter cone vacuum filter method, and relates to a vacuum oil filter. The waste oil filter cone vacuum filter method is characterized in that an upper opening of a vacuum tank is connected with a lower opening of a filter cone; an upper opening of the filter cone is provided with a waste oil spray head; a filter plate is arranged in the filter cone; filter media are arranged on the filter plate; the filter media are kaolin, kieselguhr, carclazyte, active carbon or crushed silica gel powder; and the vacuum tank is under negative pressure, the upper side of the filter plate is under normal pressure, and the lower side of the filter plate is under the negative pressure. In the method, the temperature of filter oil is low, the filter oil is difficult to oxidize and can be decolored; the filter method is easy to operate, good in filter effect, high in cleanness of filtered oil and low in filter cost; and a filter device is simple, energy-saving and convenient to install, use and maintain, and has popularization value. The method is mainly suitable for purifying and decoloring water-free waste oil.

Description

technical field [0001] The invention relates to a vacuum oil filter, to a method for filtering oil by the vacuum oil filter, and more particularly to a waste oil filter bucket-type vacuum filter method. Background technique [0002] Vacuum oil filter, also known as vacuum oil purifier, is a very popular waste oil regeneration treatment device. Mechanical impurities, so that the oil can be purified equipment. JB / T 5285-2001 "Vacuum Oil Purifier" and TL / T521-93 "Guidelines for Use and Acceptance of Vacuum Oil Purifier" have made more detailed regulations on the relevant issues of vacuum oil purifier. At present, although there are many models of vacuum oil purifiers, the vacuum oil purifier needs to use other devices to process the waste oil first, and then use a plate filter device to filter the treated waste oil. The filter method of the plate filter device It is a physical filtration method. The plate filter device pressurizes the filtered oil through an oil pump, and hea...
