Abstract

PURPOSE:To obtain an apparatus capable of coping with the demand for high preciseness of filter material and concentration of slurry liquid, by making the inside of filter material an inlet side of slurry liquid and the outside thereof a ultrasonic vibration region. CONSTITUTION:Slurry liquid 1 in a slurry liquid tank 13 is drawn by a pump 14 and forced to the inside of a rotating filter material 5 through a slurry liquid inlet pipe 4 to be classified and filtered by the filter material 5 and discharged through a filtered liquid outlet 9 to the outside to be recovered, whereas part of the slurry liquid, without going through classification and filtration, is returned to the slurry liquid tank 13 through a recycle pipe 8 formed in one body with the filter material 5. And a horn of a ultrasonic wave vibrator 11 is placed against the outer side of said filter material 5, therefore, the outside surface of the filter material 5 is brought into the vibrating region successively by the rotation of the filter material 5, so that the filter material 5 is successively regenerated by the cooperating action between the vibrating action and the recycled liquid 2 of slurry liquid 1 supplied into the filter material 5, causing the recycled liquid 2 to be returned to the tank 13 from the recycle pipe 8.

Now, to explain the classification and filtration action in detail, in the present invention, the vibrator horn 11 is located on the filtrate outlet side of the filter medium 5 (i.e., the side opposite to the liquid pressure feeding side) so that it can irradiate ultrasonic waves. Because it is made of iron, it does not increase the load on the ultrasonic oscillator or reduce the cavitation effect even when flowing at a considerable pressure (several to tens of times the pressure compared to conventional devices). Particles having a particle size smaller than the opening of the filter medium 5 pass through the filter medium 5 and are collected as the filtrate 3 from the discharge port 9. At this time, particles with a particle size larger than the opening of the filter medium 6 are temporarily captured on the inner surface of the filter medium 5, and the inflowing particles promote the formation of a cake layer. Since the outer surface of the filter medium 5 is sequentially transported to the ultrasonic oscillation area, the filter medium 5 is sequentially regenerated due to the vibration effect and the cooperative action of the slurry liquid 1 supplied into the filter medium 5 with the recycling liquid 2, and its recycling The liquid 2 is returned to the tank 13 through the recycle pipe 8.

[Effects of the Invention] The present invention is as described above, and as a result of irradiating ultrasonic waves with the vibrator horn located on the filtrate outlet side of the filter medium (i.e., the side opposite to the liquid pressure feeding side), the load on the ultrasonic oscillator is reduced. The slurry liquid 1 can be flowed in at the required pressure without increasing the pressure or reducing the effect of cavitation, and the filtration accuracy is high, allowing smooth classification and filtration even in a filter medium that is difficult to flow.

Particles with a diameter larger than the opening of the filter medium are temporarily captured on the inner surface of the filter medium, and the inflowing particles promote the formation of a cake layer. Due to the cooperation of the slurry liquid 1 supplied inside with the recycle liquid, the slurry liquid 1 is returned to the tank 13 together with the recycle liquid 2, and the filter medium is successively regenerated. This can significantly improve filtration efficiency.
