MIXING APPARATUS FOR POWDER RAW MATERIAL AND LIQUID RAW MATERIAL AND METHOD FOR MANUFACTURING MIXTURE USING SAME

摘要

A mixing apparatus is provided that evenly mixes a powder raw material and a liquid raw material. The powder raw material is supplied to and spread out on a rotating disk to form a thin layer of dispersed particle swarms close to the periphery of the rotating disk. A rotary atomizer that synchronously rotates on the same axis is provided above the rotating disk. The liquid raw material is supplied to an inside surface of the rotary atomizer. Then, the liquid raw material is conducted to an atomizing head where the liquid raw material is atomized, and droplet swarms are horizontally radiated. The dispersed particle swarms and the droplet swarms are merged and condensed within a tapered wedge-shaped space, with the result that these swarms change into a fine and homogeneous mixture. The mixture is then radiated from the periphery.

主权项

1. A mixing apparatus comprising:
a first disk configured to rotate on a vertical axis and to radiate a powder raw material supplied from a vertical axis direction in an outer edge direction; a second disk, the second disk being a stationary disk separated from a top surface of the first disk by a predetermined distance and provided in a manner such that the powder raw material radiated on the first disk is leveled in passing through a first gap formed by separating the second disk by the predetermined distance; a third disk configured to cover the second disk and to rotate on a same axis as the first disk, the third disk including an atomizing head that atomizes and radiates in an outer edge direction a liquid raw material supplied while the third disk is rotating; a fourth disk having a shorter diameter than a diameter of the third disk, fixed to the third disk, and separated from an under surface of the third disk by a predetermined distance, the fourth disk being configured to rotate on a same axis as, and in an integrated manner with, the third disk, the fourth disk including, at an outermost portion, a horizontal top surface and an under surface inclined upward toward an outer edge, the fourth disk being provided in a manner such that the atomized liquid material passes through a second gap formed between the top surface of the fourth disk and the under surface of the third disk; and a fifth disk provided below the fourth disk and separated from the under surface of the fourth disk by a predetermined distance, the fifth disk being configured to rotate on a same axis as, and in an integrated manner with, the first disk, and having a diameter that is longer than a diameter of the fourth disk, the fifth disk being provided in a manner such that the powder raw material leveled by the second disk passes through a third gap formed between a top surface of the fifth disk and the under surface of the fourth disk, wherein the under surface on an outer edge side of the third disk and the top surface on an outer edge side of the fifth disk face and fit each other in such a manner as to sandwich the fourth disk from a top surface direction and under surface direction of the fourth disk, in a fourth gap formed between the outer edge of the fourth disk, the under surface on the outer edge side of the third disk, and the top surface on the outer edge side of the fifth disk, a mixture of the liquid raw material radiated from the second gap and the powder raw material radiated from the third gap is deposited on a portion where the third disk and the fifth disk face and fit each other, and in accordance with an amount of the deposited mixture and a centrifugal force applied to the mixture, the third disk is pushed up, or the fifth disk is pushed down, to radiate the mixture in circumference directions of the third and fifth disks.
