DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes a casing main body of the multipurpose substance treatment apparatus according to the present invention.

The inner pipe 7 is connected, and the inner pipe 7 is disposed inside the intermediate casing 3.

Numeral 9 denotes a main swirling vortex space, and the main swirling vortex space 9 is annularly defined between the inner peripheral surface of the intermediate casing 3 and the outer peripheral surface of the inner pipe 7 so as to be widened downward. .

The lower casing 4 is formed in the shape of a hollow conical cylinder whose diameter decreases in the downward direction and has a circular horizontal cross section.

The lower casing 4 may be formed as a hollow polygonal pyramid having a polygonal horizontal section, and a ridge 11 projecting toward the center on the inner peripheral surface of the lower casing 4 extends vertically. May be provided.

Reference numeral 12 denotes a raw material charging cylinder. The raw material charging cylinder 12 is formed in a hollow cylinder or a hollow square cylindrical shape, and has a center at a predetermined angle α with respect to a main body center line CL of the casing main body 1.
It is provided so as to pass through the upper casing 2 and the inner pipe 7 from the outside so that the distal end port is located below the inner pipe 7 and is located in the upper portion of the lower casing 4.

Reference numeral 13 denotes a lip piece at the tip end of the material charging cylinder 12, and the lip piece 13 is provided at an angle β crossing the center line CL of the main body.

Next, the operation of the multipurpose substance treatment apparatus according to the present invention will be described. First, various physics such as crushing and crushing and spheroidization of solids, removal of substances adhering or impregnating on solids, mixing of solids, and separation of flexible substances such as plastic, metal, and rubber from solid mixtures. Regarding the formation of the processing space region X having a processing function, when the damper 6 of the upper casing 2 is fully closed and air is supplied to the main vortex space portion 9 from the air supply pipe 8, the casing main body 1 is in this state.
When the static pressure in the inside rises, the air flow is exhausted from the raw material charging cylinder 12, and most of the air supply amount is exhausted from the processed material discharge port 10 while rotating in the lower casing 4 as it is. In general, it is 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 sent to the main swirling vortex space 9 descends as a main swirling vortex and collides with the raw material charging cylinder 12 and the lip piece 13 projecting downward from the inner pipe 7. However, an ultra-high-speed vortex is generated from the collision point, and the upper and lower static pressure of the casing main body 1 is adjusted by the damper 6, so that the processing space region X is formed at a position above the lower casing 4 and the vortex is generated. The raw material W input from the outside by the ejector action
Is sucked into the processing space region X by suction at a negative pressure from the front end port.

The raw material W charged into the processing space region X is rotated in a main direction while rotating 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. It moves at high speed in all directions along the eddy current, and is repeatedly crushed and polished by mutual collision to form finely divided spheres. During this time, drying by water repellency of attached water or drying by impact heat or 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, it is guided down to the treated material discharge port 10 and discharged to the outside by downward inertial force. 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 is related to the diameter reduction angle of the lower casing 4. If the upward acceleration of the centrifugal acceleration of the main swirling vortex is too large, the processing space region X is too large. The region X rises and comes off from the upper portion of the lower casing 4, and the processing space region X is destroyed and loses its function. Therefore, the region X 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,
In addition, drying and pulverizing papermaking sludge, pulverizing and spherical pulverizing of solids for powder coating, removing adhering moisture after washing of molding sand, etc., and pulverizing and spherical pulverizing 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 an exhaust port 5 at the upper end and a processed material discharge port 10 which is open to the atmospheric pressure at the lower end. At the same time, an inner pipe 7 whose diameter is reduced downward from the lower end of the upper casing 2 is connected, and the inner pipe 7 is disposed inside the intermediate casing 3 so that the inner pipe 7 is located between the intermediate casing 3 and the inner pipe 7.
The main swirling vortex space 9 defined on, connecting the pipe 8 feeding air from a tangential direction to the intermediate casing 3 to form a horizontal section of the lower casing 4 of the casing body 1 in a circular shape, and diameter according to the lower The upper casing 2
And passing the inside of the inner tube 7 so that the tip opening is located below the inner tube 7,
In addition, since the raw material charging cylinder 12 located in the lower casing 4 is provided, 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 When it descends as the main swirling vortex and collides with the raw material charging cylinder 12, a vortex is generated and the vertical static pressure of the casing body 1 is adjusted, so that the processing space region X is formed and the inner ascending flow path is formed. By forming the U and the outer descending flow path D, the raw material W input from the outside by the ejector action of the vortex is sucked in the negative pressure from the tip end of the raw material charging cylinder 12 and injected into the processing space region X. The generation of dust to the outside at the time of material input can be prevented, and the material W charged into the processing space region X moves at high speed in all directions along the main swirling whirl while rotating, thereby performing impact crushing and polishing by mutual collision. repeat Since the minute spheroidizing can be significantly improved flowability of the powder raw material in comparison with the crushing of having corners,
In the meantime, physical treatments such as drying by water repellency of attached water or drying by impact heat and frictional heat can be performed without heating at room temperature at the same time. The production efficiency can be greatly improved, and the separation of the synthetic resin sheet and the glass in the laminated glass for automobiles, which was impossible in physical separation, and the separation of the gypsum powder and paper pieces (fiber) in the gypsum board, can also be performed.
Simultaneously with the crushing and pulverization, the high-speed air swirl has a high dispersion ratio and can 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. In this case, the linear effect is generated, and a more complicated air flow is induced to exhibit multi-functionality.
