The specific embodiment:

Shown in accompanying drawing 2-7, the specific embodiment of the utility model is following: housing 2 accumbency are on support 1, and housing 2 is made up of with end cap 27 half housing 26; The two ends of half housing 26 are opening, and big opening one end and end cap 27 usefulness bolts link together, and half housing 26 is separated with end cap 27 can conveniently overhaul, clean or change filtration screen frame 3 assemblies and hairbrush bar 5 assemblies; One oil-in 7 and exhaust outlet 8 arranged at housing 2 tops, and its underpart connects the tapered dreg collecting slot of a cross section, and there is a slag notch 11 the awl end of this groove; There are the visor of observation and maintenance window 9 in housing 2 both sides, are provided with a central shaft 4 along its axial horizontal level in housing 2 inner chambers, and an end of this central shaft 4 is connected with bearing 24 in housing 2 outsides; And stretch in the housing 2 and with housing 2 and be the sealing shape, central shaft 4 be a tubular structure, and central shaft 4 one ends seal with the stifled seam of axle;, the length at the middle part of central shaft 4 is evenly arranged through hole less than the length of housing 2 at axial direction; And on middle shaft part, be provided with and filter screen frame 3; Filter screen frame 3 and be diameter cylindric greater than axle, its two ends are fixedly connected with central shaft 4 with roundlet nut 18, baffle ring and trip bolt 19 with hold-down ring, and the interior through hole of filtration screen frame 3 is corresponding with lead to the hole site on the central shaft 4; The other end of central shaft 4 and housing 2 are the sealing shape and stretch out outside the housing 2; Central shaft 4 other ends are provided with a sprocket wheel 21 outside housing 2, sprocket wheel 21 is connected with reducing motor 12 through chain, and motor reducer can require the speed of regulating shaft according to different processes; After vegetable oil gets in the filter housing by the oil-in place, filtration screen frame 3 parts are immersed in the vegetable oil, vegetable oil gets in the frame intraformational beds through filtering screen frame 3; The oil that is filtered then enters into central shaft 4 through through hole, because central shaft 4 is in rotation status for tubular structure when working, this axle is a power transmission shaft; Be again oil discharge passage, under the continuous cleaning action of centrifugal force and vegetable oil, major part can come off very soon automatically attached to the dregs of fat that filter screen frame 3 surfaces; Be deposited in the bottom taper dreg collecting slot, also have the residual filter residue of part to brush with hairbrush bar 5, brush axle operating grip 10 is outside shell; Brush axle 6 and housing 2 sealings; Through operation brush axle operating grip 10 hairbrush bar 5 is turned an angle, and contact the filter residue of brushing filtration screen frame 3 remained on surface, can lock the position of hairbrush bar 5 through Fixed latches 22 with filtering screen frame 3; When the filter residue that is deposited on the shell bottom acquires a certain degree; Filter residue is discharged from slag notch 11, and the oil that is filtered then will be transferred out in rotary course outside the housing 2 by hollow shaft, realizes the purpose that works long hours continuously.

Described maintenance window 9 is made up of hold-down ring 28, glass 29, liner 30; Link together through bolt and housing 2; Both can observe function situation in the shell in the filter work from here; Can when component faults appears in machine intimate, keep in repair from here and clean again, remove the complicated procedures of dismounting end cap 27 from, shortened machine maintenance cycle, saved maintenance time, make the machine can be in running order for a long time.

Described filtration screen frame 3 is connected through slim flat key axial location with central shaft 4; The through hole that filters in the screen frame 3 is corresponding with the lead to the hole site on the central shaft 4; A plurality of filtration screen frames 3 closely are arranged in through the slim flat key orientation on axle of the keyway on the wheel hub; To filter screen frame 3 clampings with baffle ring and trip bolt 19, hold-down ring and primary nut 18 respectively at central shaft 4 two ends and prevent to filter the axial float that screen frame 3 produces because of rotation; When screen frame 3 is filtered in need dismountings, only need primary nut and hold-down ring 18 shed and get final product, very convenient fast; Filtering in the screen frame 3 has stainless steel filtering net 23, and filter screen is in screen pack frame bracket 15 both sides and encase with canvas strips 14, compresses with big trim ring 16, little trim ring 17 again; Having guaranteed the required precision of filtering, is the body structures that combined by framework 15 and sieve sheet 13 filtering screen frame 3 inside, and sieve sheet 13 evenly is covered with the circular steel plate in hole for annular; Play the effect of filtering screen frame 3 of reinforcing; More guarantee to filter the flatness of screen frame 3, prevented the distortion of filtration screen frame, the service life that guarantees to filter screen frame.

Described hairbrush bar 5 is connected through slim flat key axial location with brush axle 6; Corresponding keyway closely links together through slim flat key location on keyway on a plurality of hairbrush bar 5 axle sleeves and the brush axle 6; The position of its hairbrush bar 5 just in time can be fixed with circlip and little round nut at brush axle 6 two ends filtering rotation between the screen frame 3, when need dismounting hairbrush bar 5; Shed little round nut and get final product, very convenient dismounting; Rotatable brush axle 6 is regulated the position of hairbrush bar 5; Make the hairbrush bar and filter screen frame and contact or throw off contact; During when the filter residue that needs hairbrush bar 5 cleaning filtration screen frames 3 or without hairbrush bar 5 or cleaning maintenance hairbrush bar 5; Can brush axle 6 be stuck in latch 22 fixed-site, both convenient for cleaning, convenient for maintaining again.

For screen frame 3 assemblies, hairbrush bar 5 and maintenance central shaft 4 are filtered in replacing for convenience detach; Only need the bolt of bolt that dismounting end cap 27 is connected with half housing 26, sealing devices that end cap 27 is connected with central shaft 4, the jackscrew on the bearing 24 outward; Just can shift out end cap 27 and support thereof; Welding pulley 25 below end cap 27 supports, not only laborsaving but also convenient.

The utility model be suitable for that vegetable oil material leaches or other extraction process after to the filtration of filter residue in vegetable oil or the extract and solid impurity, overcome traditional plant oil filter plant weak effect, be prone to cause filter screen to stop up; The filter screen distortion is not easy to clean maintenance, can not realize the shortcoming of long time continuous working; And compact conformation, convenient disassembly are simple to operate; Labour intensity is low, good filtration effect, and the cleaning maintenance is convenient and simple.
