Background

The centrifugal filter is a common filtering device, the application field of the centrifugal filter is relatively wide, but the common centrifugal filter generally filters dregs in liquid directly, and the common filter completes the oil purification function by using a filter screen, and has the defect that fine particle impurities can easily pass through the filter screen or be blocked by larger pollutants so as to reduce the flow of lubricating oil until the machine is finally completely blocked, so that the machine is damaged. The contents of dregs in different liquids are different, and the replacement frequency of the filter core of the liquid with much dregs is relatively common; if some sewage can be filtered, the phenomenon of filter screen blasting can occur, and most of the large particles or impurities can not be removed in advance by the principle. The centrifugation and filtration technology is widely applied to the industrial fields of petrifaction, metallurgy, chemical engineering, biology, food, energy, machinery, electric power, coal, wine, textile, pharmacy, sanitation and the like. The centrifugal apparatus used in the present invention is an apparatus for separating solid-liquid, liquid-solid, and solid-liquid phases ("liquid" is used broadly herein to refer to a fluid including a liquid phase and a gas phase), and the application fields thereof include dehydration, clarification, fractionation, concentration, separation, and the like.

In general, centrifugal filtration is a method in which a suspension solution is passed through a filter medium by centrifugal force, so that solid particles are retained in the filter medium and are accumulated into a cake, and a liquid is filtered into a filtrate through a cake layer and a filter medium. Such conventional centrifuges/filters are of the three-leg type, flat plate type, top-hung type, side-filtered type, scraper discharge, piston push, screw discharge, centrifugal force discharge, vibratory discharge, precessional discharge, bag-turning discharge, etc., and the detailed construction and principle of these centrifuges or filters can be referred to in the manual of "industrial centrifuges and filters selection manual" (ISBN 978-7-122 and 18787-1, which is incorporated herein by reference in its entirety).

The prior art discloses a filter suitable for quenching oil centrifugal filter, including filter cartridge and the filter screen that is located filter cartridge, filter cartridge is equipped with the fagging including relative oil inlet and the oil-out that sets up between oil inlet and the oil-out, the fagging with the opening direction of oil inlet and oil-out all is 45 contained angles, and the filter screen is hung on the fagging, the mesh aperture of filter screen is 1~3 mm.

Above-mentioned scheme can avoid thereby the damage of centrifugal filter front end coarse filtration in the quenching oil groove to make whole filter all damaged to connect through the flange cooperation, realize the sealed of connecting portion. However, in the harsh industrial standard of particle size, a larger centrifugal force and a denser filter material are often required to separate smaller particles, and the smaller particles easily block the filter material, which makes subsequent centrifugal separation and filtration difficult, so that the operation is frequently suspended to clean the filter material and/or eliminate the replacement of the filter material, which increases time and cost. Therefore, a centrifugal separation apparatus which can reduce the scale formation, can be operated easily, and can separate particles and a clear liquid is required.
