Under the effect of centrifugal force, get rid of the diatomaceous earth and the wax composition in the crude oil to the separator outside, the second circular port 332 of even setting is seted up to first toper ring 33 side, the liquid in separator outer space flows into to first toper ring 33 inner space along second circular port 332, the diatomaceous earth and the wax composition in the centrifugal force that produce through the high-speed rotation of rotor plate 34 remove to the separator outside with the diatomaceous earth and the wax composition in the liquid, be less than top opening diameter through second toper ring 32 bottom opening diameter, can help diatomaceous earth and the wax composition of separator inside to remove to the separator outside under the effect of centrifugal force, simultaneously, diatomaceous earth and the wax composition of separator outside can't enter into the separator inner space easily owing to blockking of second toper ring 32.

Through set up the spout 36 that corresponds the design with fixture block 331 in filter tank 3 is inside, fixture block 331 can slide in spout 36 is inside, when the diatomaceous earth and the wax composition of separator outer space pile up too much, open the lid at filter tank 3 top, through removing the fixture block 331 on the surface of first conical ring 33 in the vertical portion of spout 36, move the separator upwards along the vertical portion of spout 36, the in-process of separator rebound drives the outside diatomaceous earth and the wax composition synchronous motion of separator, be convenient for relevant staff to clean the diatomaceous earth and the wax composition that filter tank 3 is inside to persist, after the cleanness, move fixture block 331 to spout 36 bottom along spout 36, then slide fixture block 331 to in the spout 36 of horizontal direction.

Inside diatomaceous earth entered into discharging device along feeder hopper 12, motor 15 drove discharging device at the in-process of stirring and puts into diatomaceous earth to agitator tank 1 is inside.

After the diatomite is thrown into the feed hopper 12, the diatomite enters the gap between the first annular plate 13 and the second annular plate 131, the motor 15 synchronously drives the second annular plate 131 to rotate in the rotating process, and the diatomite in the gap between the first annular plate 13 and the second annular plate 131 is thrown into the space in the stirring tank 1 in the rotating process of the second annular plate 131.

The stirring plate 17 drives the crude oil and the diatomite to rotate and to collide with the surface of the spoiler 16 in the rotating process, and the rectangular groove 161 and the stirring plate 17 are correspondingly designed, so that the crude oil and the diatomite rotate and collide with the surface of the spoiler 16 and then are matched with the stirring plate 17 to rotate in the rectangular groove 161, and the mixing effect of the crude oil and the diatomite is further improved.

And filtering the edible oil again by using an oil outlet device, and leaving residual micro kieselguhr particles in the edible oil at the bottom of the filtering tank 3.

When the edible oil liquid level of filtering 3 bottoms of jar is higher than the position height of floating block 372, the buoyancy that utilizes floating block 372 drives telescopic link 37 and upwards extends, the edible oil of filtering 3 bottoms of jar is in the preferential discharge when same position height with fourth circular port 371, the edible oil of other liquid level heights is in quiescent condition, at this in-process, unfiltered complete diatomaceous earth granule can deposit in the edible oil of other liquid level heights in filtering jar 3 bottoms, until when highly uniform with fourth circular port 371 place position, the edible oil side can be followed fourth circular port 371 and is discharged in entering into defeated oil pipe 31.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed.
