2. Description of the Related Art Generally, when solid particles in a fluid are given a mechanical force such as gravity, inertial force, centrifugal force, the mechanical force received by each particle is proportional to the cube of the particle size. On the other hand, the reaction force such as buoyancy and Stokes force (viscous resistance received from the fluid when the particle size is sufficiently small) that each powder or granular material receives is proportional to the square of the particle size. It is known that the reaction force of the small particle size is larger than that of the large particle size. That is, in the case of particles having the same component but different particle diameters, due to the difference in the particle size, and in the case of particles having substantially the same particle diameter with different components, due to the difference in the specific gravity, the mechanical force exerted on the particles in each case is And the reaction force is different, the movement paths of the particles are different and the particles can be separated. Further, the powdery- or granular-material separating device configured based on such a principle includes a classifier for classifying particles having different particle sizes and a classifier for selecting particles having different specific gravities.

The sorting machine crushes household or industrial wastes such as electric appliances, furniture fixtures, containers, automobiles and building constructions, and mixes each component such as metal, glass, wood, rubber and plastic. There is a method for selecting the powder or granular material in the formed state. This sorter is used from the following viewpoints. The above-mentioned disposal of waste is carried out by pulverizing it into powder particles having a substantially uniform particle size for the purpose of limiting the disposal space and reducing transportation and storage costs. However, there is a limit to the disposal from the viewpoint of environmental protection, and it is desirable to select and collect each mixed component from the viewpoint of saving useful resources. That is, the sorter is used to sort and collect each component from the mixed powder and granules in a reproducible form. The classifier includes a gravity type (floating fractionation type), an inertial force type, and a centrifugal force type (cyclone type), like the classifier.

The gravity type classifier described above requires not only a large amount of fluid for classifying powder particles on a fluid rising in a buoyancy cyclone, but also collision between particles. In order to prevent the interference with the buoyancy due to the above, it is unavoidable to dilute the particle concentration (the ratio of the powdery particles contained in the fluid) extremely, and the processing amount per space in the buoyancy cyclone is small, so that the efficiency is remarkably poor. Further, there is a disadvantage that a collecting device for the powder particles after classification is required in addition to the classifier. Similarly, the inertial force type can obtain a large classification force next to the centrifugal force type described later, but like the gravity type, a large amount of fluid is required, and the particle concentration has an upper limit. Similar to the gravity type, since a separate collecting device is required, it has a drawback that it is large and has a complicated mechanism. Similarly, the centrifugal force type can obtain a classification force larger than those of the gravity type and the inertial force type and can perform accurate classification, but it is easily affected by the particle concentration in the fluid and the accuracy of the powder and granular material is high. In order to prevent collision interference between particles, the particle concentration cannot be raised above a certain amount. That is, it is not suitable for large-scale processing and has a drawback that a separate collecting device is required like the gravity type and inertial force type.

The gravity type of the sorting machine is used for powder particles in a mixed state in which the difference in specific gravity between particles is relatively small, but a liquid is used for sorting with a small difference in specific gravity.
Therefore, there is a drawback that an apparatus for recovering the powder or granules from the liquid is required after the separation into each component, and the size and complexity must be increased. Similarly, the inertial force type is
It is used for mixed powder and granules where the difference in specific gravity of each particle is large, but the space for separating such mixed powder and granules is inevitably large, and the device must inevitably be large. There is. Similarly, the centrifugal force type can be used relatively easily and can be downsized, but the sorting accuracy is generally low, and the accuracy is particularly remarkable when the difference in specific gravity between the particles of the granular material is small. There is a drawback.

The operation and effect of the above embodiment will be described below. When the fine particles 1a including the small particles 1a and the large particles 1b having the large particle diameters are sent to the swirl introduction portion 2a of the first cyclone A together with air,
The fine particles 1a ... And the coarse particles 1b .... Swirl flow through the swirl introducing section 2a toward the separating section 6 and receive centrifugal force. The fine particles 1a, which have been subjected to the centrifugal force, have a larger reaction force per weight than the coarse particles 1b, which are received from the air, so that the fine particles 1a, ... On the contrary, whirling flow occurs while displacing to the outer peripheral side of the swirl introducing section 2b while taking a path, and the particle size is large from the outer peripheral side of the swirl introducing section 2a toward the inner peripheral side, that is, in the width direction of the swirl introducing section 2a. They are arranged in order. In addition, each new style guide vane 8
The newly introduced inflowing air flowing into the swirl introducing part 2a through the open part between the ... hits the granular material 1 flowing in the swirl introducing part 2a ... It will be further strengthened. Then, the granular materials 1 ... Inflowing into the separating portion 6 in the strengthened aligned state are slightly spread in the width direction of the separating portion 6 while maintaining the state, and are separated on both sides by the separating blade 7. To be done. After the separation, the granular material 1
Of the fine particles 1a ... in the first cyclone A,
Further, the coarse particles 1b ... Enter in the second cyclone B, respectively. The fine particles 1a that have entered the first cyclone A and the air are further swirled therein to be separated into gas, and the fine particles 1a ...
Is dropped and sucked and discharged from the underflow portion 3a and the air from the overflow portion 4a to the outside. On the other hand, the coarse particles 1b, which have entered the second cyclone B, and the air are further swirled in the second cyclone B while being gas-separated, and the coarse particles 1b ...
Is dropped and is sucked and discharged from the underflow portion 3b and the overflow portion 4b to the outside for classification. In this classifier, the boundary of the classifying set particle size can be arbitrarily changed by rotationally displacing the separating blade 7, and the dampers 12a and 12b are displaced so that the amount of air flowing in the respective overflow portions 4a and 4b. If the ratio is adjusted, the air flow in each part of the apparatus, especially the air flow in the separation part 6 changes, and the boundary of the classification setting particle size is slightly displaced. Therefore, the boundary can be finely adjusted and the classification work can be facilitated. Can be done. In this case, the air amount ratio is 1
While checking in step 3, the dampers 12a and 12b are opened and closed for adjustment.
