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

Waste oil pan formula vacuum filtration method
Technical field
The present invention relates to vacuum oil-filter, relate to the method for vacuum oil-filter filter oil, more specifically relate to a kind of waste oil pan formula vacuum filtration method.
Background technology
Vacuum oil-filter has another name called vacuum oil purifier, it is a kind of very universal waste oil regeneration treating apparatus, it is a kind of degassing under certain vacuum and oily temperature condition, dehydration, and leaches mechanical admixture with specific filter medium, thus the equipment that fluid is purified.JB/T 5285-2001 " vacuum oil purifier " and TL/T521-93 " vacuum oil purifier use check and accept guide rule " are to the relevant issues of the vacuum oil purifier detailed regulation of contrasting.At present, though the type of vacuum oil-filter is a lot, but, vacuum oil-filter needs with other device waste oil to be handled earlier, then, adopts board-like filter that the waste oil after handling is filtered, the filter method of board-like filter is the physical filtering method, board-like filter is by oil pump filter oil to be pressurizeed, and carries out physical filtering after by heater filter oil being heated, and emphasis is the impurity that filters in the waste oil.The deficiency of its board-like filter is: the oil temperature is higher, the easy oxidation of filter oil, and filter oil can not be decoloured, and filter operation is loaded down with trivial details, and it is perishable to cross filter core, and the luboil cleanness of filtration is relatively poor, and it is higher to filter cost, for this reason, the filter method of the vacuum oil-filter that haves much room for improvement.
Summary of the invention
Purpose of the present invention: a kind of waste oil pan formula vacuum filtration method is provided.
Technical scheme of the present invention is: a kind of waste oil pan formula vacuum filtration method, and it is characterized in that: the end opening of the suitable for reading and pan of vacuum tank is connected, and the pan waste oil spray head that is provided with suitable for reading is provided with filter in pan, be provided with filter medium on filter; Filter medium is kaolin, diatomite, carclazyte, active carbon or pure silica white; Vacuum tank is a negative pressure, and making the top of filter is normal pressure, and the below of filter is a negative pressure.
Described filter medium is one or more a mixture in kaolin, diatomite, carclazyte, active carbon or the pure silica white, and the order number of filter medium is the 10-300 order.
Described waste oil pan formula vacuum filtration method, the oily temperature control of its waste oil is at 0 ℃-150 ℃.
The negative pressure of described vacuum tank is 0.001-0.1Mpa.
Be provided with leak oil line in vacuum tank, leak oil line is with the fuel-displaced bottom of guiding to vacuum tank of pan end opening.
Operation principle of the present invention: vacuum tank is vacuumized with vavuum pump, simultaneously, the waste oil that spray head will need to filter sprays into pan, under the effect of vacuum tank negative pressure, waste oil passes through filter medium, waste oil and filter medium generation physical-chemical reaction, some impurity in the waste oil and filter medium are deposited on the filter medium after producing flocculation, and some impurity that chemical reaction do not take place also are filtered medium and carry out physical filtering.
Beneficial effect of the present invention: waste oil pan formula vacuum filtration method of the present invention, its filter oil temperature is lower, filter oil is difficult for oxidation, filter oil can be decoloured, and filter operation is simple, good filtration effect, the luboil cleanness that filters is high, it is very low to filter cost, and filter is simple, economize on electricity, installation, use, easy to maintenance, has promotional value.The mainly suitable water-free waste oil of waste oil pan formula vacuum filtration method of the present invention purifies and decolours.
