Next, the operation of the multipurpose substance treatment apparatus according to the present invention will be described. First, crushing and spheroidization of a solid substance, removal of a substance adhered or impregnated on a solid substance,
Mixing of solids, plastics, metals, from solid mixtures,
Regarding the formation of the processing space region X having various physical processing functions such as separation of a flexible substance such as rubber, the upper casing 2
With the damper 6 fully closed, the main vortex
When air is supplied to the space 9 , in this state, the static pressure in the casing body 1 increases, so that the air flow is exhausted from the raw material charging cylinder 12 and the lower casing 4
Most of the air supply amount is exhausted from the processing object discharge port 10 while turning inside, and it is substantially difficult to form the processing space region X.

When the damper 6 is opened and the opening amount of the exhaust port 5 of the upper casing 2 is adjusted, a part of the air supply amount is exhausted from the exhaust port 5, so that the static pressure in the casing body 1 decreases. As a result, an inner rising flow path U which rises while turning between the inner pipe 7 and the processed material discharge port 10 of the lower casing 4 is formed, and the inner rising flow path U and the inner peripheral surface of the lower casing 4 are formed. An outer descending flow path D that descends while turning is formed.

At the same time, the air flow supplied to the main swirling vortex space 9 descends as a main swirling vortex, thereby colliding with the raw material charging cylinder 12 and the lip piece 13 projecting downward from the inner pipe 7. and, together with the ultra high-speed vortex is generated from such a collision point, because the upper and lower static pressure of the casing body 1 is adjusted by the damper 6, with the processing space region X is formed at the upper portion of the lower casing 4, the vortex The raw material W supplied from the outside by the ejector action is suctioned at a negative pressure from the front end of the raw material charging cylinder 12 and is supplied to the processing space region X.

The raw material W charged into the processing space region X is caused by a high-frequency vibration wave generated by an ultra-high-speed vortex generated by colliding with the raw material charging cylinder 12 and the lip piece 13 .
The raw material W rotates at a high speed in all directions along the main swirling vortex while rotating, and is repeatedly crushed and polished by mutual collision to be subdivided into spheroids. Drying by friction heat is performed.

It has been confirmed that the rotation axis of the raw material W is parallel to the center line CL of the main body.

After being taken into the main swirling vortex in the processing space region X and processed for a certain period of time, those having a large particle size and mass are moved toward the inner peripheral surface side of the lower casing 4 by centrifugal force to form an outer descending flow path. D and descend to the processed material discharge port 10
Are discharged to the outside by a downward inertial force, and those having a small particle diameter and mass move toward the center side, and the inner ascending flow path U
Through the exhaust port 5.

A part of the finely divided powder rides on the inner ascending flow path U, and the powder having a large particle size and density while rising rises to the outer descending flow path D or the processing space area X by centrifugal force due to the swirling flow. Returned to and reprocessed.

The amount of super-high-speed vortex generated to form the processing space region X and the vortex velocity are determined by the shape, mounting angle, and lip piece 13 of the raw material charging cylinder 12 projecting downward from the inner pipe 7. Therefore, it is possible to set optimal conditions for physical processing depending on the type of the raw material W.

The damper 6 of the upper casing 2 has the function of adjusting the static pressure itself of the casing body 1 and the function of adjusting the static pressure above and below the processing space area X. The upper and lower positions can be set stably using the difference in the area of the lower surface, and the vertical thickness and diameter of the processing space region X can be changed by shifting the vertical position to control the centrifugal force due to the main swirling vortex. Therefore, the crushing power and the processing density can be adjusted.

Furthermore, by forming the horizontal cross section of the lower casing 4 into a polygonal shape or by providing the protruding ridges 11, the air flow on the inner peripheral surface of the lower casing 4 causes a kinking motion to induce a more complicated air flow. Demonstrate multi-functionality.

The processing space region X is formed by the balance between the air supply pressure on the upper surface and the air pressure flowing into the inner return passage, and the amount of the raw material W that can stay in the processing layer is constant. Since the crushing particle size changes, the particle size can be adjusted by changing the input amount.
When 00% receives the raw material supply and reaches about 110%, about 20%
A mechanism of releasing the processed product by about 30% to about 80 to 90%, continuously receiving the raw material W until the next release, and releasing the raw material W again to about 110% is repeated.

The processing space region X is formed near the upper portion of the lower casing 4 and has a reduced diameter angle of the lower casing 4.
(Diameter reduction ratio), if the upward acceleration of the centrifugal acceleration of the main swirling vortex is too large, the processing space area X rises and deviates from the upper part of the lower casing 4, and the processing space area X
Is destroyed and loses its function, and is maintained by adjusting the air supply speed and the static pressure by the damper 6.

Next, examples of application of various raw materials W include drying and pulverization of a nodular dewatered cake in plating sludge,
Drying and pulverization of papermaking sludge, pulverization of solids for powder coatings and spheroidal pulverization, removal of adhering moisture after washing of foundry sand, etc., and pulverization and spherical pulverization of tile chamotte. It is a process of pulverizing, drying, and mixing various clays (composite soils) as raw materials for the ceramic industry, and a dry powdering process such as pulverizing and drying of coal.

Further, the gypsum board waste material is crushed and separated into gypsum powder and paper pieces or fibers, and the synthetic resin sheet which is the center material of the laminated glass for automobiles, the gas attached to both sides is separated, and the glass is crushed spherically. And separation of oxides and nitrides from aluminum dross metal to which oxides and nitrides adhere.

It should be noted that this application is only a few examples, and in short, any substance can be used as long as it contains a solid that can be crushed, separated, separated, and the like by collision.

[0032]

In short, according to the present invention, a damper 6 for adjusting the opening amount is provided in the upper casing 2 of the hollow casing main body 1 having the exhaust port 5 at the upper end and the processed material discharge port 10 open to the atmospheric pressure at the lower end. At the same time, an inner pipe 7 whose diameter is reduced below the lower end of the upper casing 2 is connected, and the inner pipe 7 is disposed inside the intermediate casing 3, and an air supply pipe 8 is connected to the intermediate casing 3 from a tangential direction. The horizontal cross section of the lower casing 4 of the main body 1 is formed in a circular shape, and the diameter thereof is reduced in the downward direction. Further, since the raw material charging cylinder 12 located in the lower casing 4 is disposed, the opening amount of the exhaust port 5 is adjusted by the damper 6, and the air flow sent from the air supply pipe 8 to the main swirling vortex space 9 is Main swirl vortex When lowered to collide with the raw material charging tube 12, the vortex flow is generated, because the upper and lower static pressure of the casing body 1 is adjusted, along with the processing space region X is formed, the inner rising flow path U and outer downward flow path By the formation of D, the raw material W input from the outside by the ejector action of the vortex is sucked under a negative pressure from the distal end of the raw material charging cylinder 12 and is injected into the processing space region X. Can be prevented, and the raw material W charged into the processing space region X moves at high speed in all directions along the main swirling whirl while rotating, and is repeatedly crushed and polished by mutual collision to be subdivided into spherical particles. Therefore, the fluidity of the powder raw material can be significantly improved compared to the crushing having corners, and physical treatments such as drying by water repellency of attached water or drying by impact heat and frictional heat are simultaneously performed at room temperature. It can be done without heating, so the production efficiency can be remarkably improved as compared with the case of processing by combining conventional single-function devices, and the synthetic resin sheet in automotive laminated glass that could not be physically separated. separation of the glass, can also be carried out the separation of the gypsum powder and paper in gypsum board (fiber), and
High dispersion rate due to high-speed air vortex at the same time as crushing / crushing
Ku, Ru can also be used for mixing.

Further, the processing space region X can be fixed by shifting the position of the lower casing 4 up and down by adjusting the opening amount by the damper 6, and when the diameter reduction ratio of the lower casing 4 is constant, the processing space region X can be fixed. Since the centrifugal force due to the main swirling vortex can be controlled by changing the diameter of the space region X, the crushing force can be adjusted, and the amount of the raw material W that can stay in the processing space region X is constant. Can be arbitrarily adjusted by changing the degree of crushing.

Further, the horizontal cross section of the lower casing 4 is formed in a polygonal shape, and a ridge 11 projecting in the center direction is provided on the inner periphery of the lower casing 4, so that the air flow on the inner peripheral surface of the lower casing 4 is formed. Folding motions occur in the air, which induces more complicated air flow and exerts multifunctionality.

Further, since the diameter reduction ratio of the lower casing 4 is not constant , the direction and acceleration of the upward component and the downward component in the centrifugal acceleration of the main swirling vortex are changed by changing the vertical position of the processing space area X. Further, since the diameter can be adjusted by changing the diameter of the processing space region X, the crushing force can be adjusted, and the practical effect thereof is extremely large.
