The discharge port 5 is provided at a central portion of the upper wall of the upper body 22 of the container 2. Further, the inner diameter of the powder or granule nozzle 3 is slightly larger than the inner diameter of the gas nozzle 4 to eject the powder or granule.

A block member 6 is disposed at a central portion of the inside of the container 2. The lower body 61 at the lower portion of the block member 6 has a cylindrical shape, and the upper upper portion 62 has a conical trapezoidal shape. The upper end surface of the lower body 61 coincides with the lower end surface of the upper body 62. As a result, the cross-sectional area with respect to the horizontal plane is such that the lower body 61 is larger than the upper body 62. Moreover, the cross-sectional area of the block member 6 with respect to the horizontal plane is formed to become smaller as it goes upward from the lower end surface of the upper body 62. The height of the block member 6 is lower than the height of the lower portion 21 of the container 2 and is less than or less than half the height of the discharge port 5. The height of the granular body nozzle 3 and the gas nozzle 4 is located near the boundary between the lower body 61 and the upper body 62 of the block member 6.

In the position of the granular body nozzle 3 and the gas nozzle 4, the block member 6 The cross-sectional area of the lower body 61 with respect to the horizontal plane is 1/6 or more and 1/3 or less of the sectional area of the lower body 21 of the container 2 with respect to the horizontal plane.

The processing chamber 11 has a receiving port 11a connected to the other end of the connecting passage 12 at the upper wall portion.

Figure 2 is a cross-sectional view taken along line II-II of Figure 1. As shown in Fig. 2, the granular body nozzle 3 and the gas nozzle 4 are disposed in a lower portion 21 of the container 2 having a circular cross section at a slightly equal interval. In the present embodiment, the granular body nozzle 3 is provided with one. The gas nozzle 4 is provided with three (gas nozzles 41 to 43). Further, the powder or granule nozzle 3 and the gas nozzle 4 spray the powder particles and the carrier gas in the swirl direction R in the container 2 from the upper viewpoint.

The gas nozzles 41 to 43 have a fine waist structure (middle fine structure) 41a to 43a in the air passage (wind tunnel) through which the carrier gas passes. The gas nozzles 41 to 43 have orthogonal direction components in the ejection direction of the powder or granular nozzle 3 or the gas nozzles 41 to 43 on the downstream side of the powder particle and the swirl direction R of the carrier gas adjacent to the container 2 . The carrier gas is sprayed in the direction. In addition, the "jet direction" here means the direction of the extension line of the center line of a nozzle.

Specifically, the injection direction A1 of the gas nozzle 41 is within a range of an angle θ1 formed by the injection portion connecting straight line L11 and the tangent line L12, and the injection portion connecting straight line L11 is connected to the downstream side of the swirling direction R and the swirling direction R. Powder granule injection part of the side granular nozzle 3 (adjacent to the powder granule spray The shot portion 3a, the tangent line L12 is from the gas ejecting portion 41b to the block member 6. As a result, the injection direction A1 of the gas nozzle 41 has an orthogonal direction component to the injection direction B1 of the granular body nozzle 3. The gas nozzle 41 preferably ejects the carrier gas from the injection portion connecting line L11 toward the inside of the container 2 at an inclination angle θ (for example, about 5 degrees) so that the injection direction A1 converges within the range of the angle θ1. In the present invention, the powder particles are collided by the use of the carrier gas to promote the pulverization of the powder or granules. However, immediately after the carrier gas is ejected from the gas nozzle, the gas flow of the carrier gas is fast, and it is difficult to have the powder or granules. Therefore, the angle θ is preferably set to be equal to or larger than the distance D1 (about 10 mm) between the injection direction A1 and the powder/particle injection unit 3A of the granular particle nozzle 3.

The injection direction A2 of the gas nozzle 42 is in a range of an angle θ2 between the injection portion connecting straight line L21 and the tangent line L22 from the gas injection portion 42b to the block member 6, and the injection portion connecting straight line L21 is connected to the gas injection portion 42b and adjacent thereto. A gas injection portion (adjacent gas injection portion) 43b of the gas nozzle 43 on the downstream side in the swirl direction R. As a result, the injection direction A2 of the gas nozzle 42 has an orthogonal direction component with respect to the injection direction A3 of the gas nozzle 43. The gas nozzle 42 preferably has an inclination angle θ from the injection portion connecting line L21 toward the inside of the container 2 so that the ejection direction A2 converges within the range of the angle θ2 (for example, about 5 degrees, which is substantially the same as the inclination angle of the ejection direction A1) To spray the carrier gas. Further, the angle θ is preferably set so that the injection direction A2 is different from the gas injection portion 43b of the gas nozzle 43 by a distance D2 (about 10 mm) or more.

The injection direction A3 of the gas nozzle 43 is within a range of an angle θ3 between the injection portion connecting straight line L31 and the tangent line L32 from the gas injection portion 43b to the block member 6, and the injection portion connecting straight line L31 is a connecting gas jet. The portion 43b is adjacent to the gas injection portion (adjacent gas injection portion) 41b of the gas nozzle 41 on the downstream side in the scroll direction R. As a result, the injection direction A3 of the gas nozzle 43 has an orthogonal direction component with respect to the injection direction A1 of the gas nozzle 41. The gas nozzle 43 preferably has an inclination angle θ from the injection portion connecting straight line L31 toward the inside of the container 2 such that the injection direction A3 converges within the range of the angle θ3 (for example, about 5 degrees, and the angle is substantially the same as the inclination angle of the injection direction A1). ) to spray the carrier gas. Further, the angle θ is preferably set so that the injection direction A3 is different from the gas injection portion 41b of the gas nozzle 41 by a distance D3 (about 10 mm) or more.

Similarly to the gas nozzles 41 to 43, the injection direction B1 of the powder or granular nozzle 3 is within a range of the angle θ4 between the injection unit connecting line L41 and the tangent line L42 of the bulk member 6 from the powder/particle injection unit 3a, and the injection unit. The connection line L41 is a gas injection unit (adjacent gas injection unit) 42b that connects the powder/particle injection unit 3a and the gas nozzle 42 that is adjacent to the downstream side in the scroll direction R. As a result, the injection direction B1 of the granular/granular nozzle 3 has an orthogonal direction component with respect to the injection direction A2 of the gas nozzle 42. The powder or granule nozzle 3 preferably has an inclination angle θ from the injection portion connecting straight line L41 toward the inside of the container 2 so as to converge in the range of the angle θ4 (for example, about 5 degrees, and the inclination angle of the angle with the injection direction A1). Slightly the same) to spray the powder and granules. Further, the angle θ is preferably set so that the injection direction B1 is different from the gas injection portion 42b of the gas nozzle 42 by a distance D4 (about 10 mm) or more.

The processing device 10 performs the following operations.

In the pulverizing apparatus 1, the granules are ejected from the granule nozzle 3 into the container 2, and the carrier gas is ejected from the gas nozzle 4 into the container 2. Furthermore, the powder or granules and the carrier gas may be mixed from the powder or granule nozzle 3 to be sprayed, so that the powder granules can be smoothly carried out. injection.

The carrier gas ejected from the gas nozzle 41 collides with the powder or granules ejected from the powder/body nozzle 3, and pulverizes the powder or granule. Further, the carrier gas ejected from the gas nozzle 42 collides with the carrier gas ejected from the gas nozzle 41 and the powder or granules ejected from the powder/body nozzle 3, and further pulverizes the powder or granule. Further, the carrier gas ejected from the gas nozzles 43 collides with the carrier gas ejected from the gas nozzles 41 and 42 and the powder or granules ejected from the powder/body nozzle 3, thereby pulverizing the powder or granules.

The powder or granule pulverized by the carrier gas sprayed from the gas nozzle 4 is vortexed around the bulk member 6 together with the carrier gas, and is further pulverized and directed upward. Further, without the height of the bulk member 6, the diffusion of the pulverized powder or granules is promoted, and the re-agglomeration of the granules is suppressed, and the granules are vortexed and directed upward. Further, the powder or granules and the carrier gas are discharged from the discharge port 5 provided at the central portion of the upper wall of the upper portion 22 of the container 2.

The powder or granules discharged from the discharge port 5 and the carrier gas pass through the communication passage 12 connected to the discharge port 5, and are discharged downward from the receiving port 11a of the processing chamber 11 into the processing chamber 11. The processing chamber 11 receives the powder or granules in the processing chamber 11 and performs predetermined processing such as heat treatment.

According to the processing apparatus 10 of the above configuration, the following effects can be exhibited.

(1) Since the carrier gas is ejected in a direction having an orthogonal direction component with respect to the injection direction of the powder or granule nozzle 3 or the gas nozzle 4 on the downstream side of the vortex direction R of the powder or granule and the carrier gas, The carrier gas is sprayed to further pulverize the powder and granules, thereby reducing the ratio of the granules which can no longer be coagulated and pulverized.

(2) The granules can be further pulverized by the carrier gas sprayed, because This can reduce the amount of carrier gas introduced into the container 2.

(3) By arranging the block member 6 at the center of the container 2, the vortex of the container and the carrier gas in the container 2 can be smoothly slid. Further, the ratio of discharge from the discharge port 5 can be reduced without the powder particles colliding with the carrier gas.

(4) The pulverizing apparatus 1 pulverizes the agglomerates of the granules by directly colliding the carrier gas against the granules. When the carrier gas directly collides with the block member 6, the airflow in the container may be disordered, and the wear of the block member 6 becomes conspicuous, so the ejection direction is preferably set from the tangential direction to the block member 6 toward the outside of the container 2. .

Further, since the speed at which the powder particles and the carrier gas are suppressed is attenuated along the inner wall surface 7 of the container, the direction of the powder or granule nozzle 3 and the gas nozzle 4 is preferably from the upper side of the injection line. The center of the container 2 is inclined.

In view of the above, by ejecting the carrier gas in a range in which the injection portion connecting straight line and the line from the gas injection portion to the tangent to the block member 6, the carrier gas collides with the powder or granule at an appropriate angle, thereby facilitating the injection of the carrier gas. The pulverization of the granules.

(5) Since the horizontal cross section of the container 2 has a circular shape, the powder granules and the carrier gas can be smoothly vortexed in the container 2.

(6) Since the horizontal cross section of the block member 6 has a circular shape, in the container 2, the powder or granule and the carrier gas can be smoothly circulated around the block member 6.

(7) Since a predetermined gap is provided between the upper end portion of the block member 6 and the upper wall of the container 2, the diffusion of the pulverized powder or granule can be promoted. And inhibit the re-agglomeration of the powder and granules.

(8) Since the gas nozzle 4 ejects the carrier gas in a range from the angle of θ1, θ2 or θ3 from 5 degrees from the line connecting the injection portion toward the inside of the container, the carrier gas collides with the powder at an appropriate angle. And it can promote the pulverization of the powder or granule by the jet carrier gas.

(9) Since the powder-particle nozzle 3 and the gas nozzle 4 are provided in a total of 3 to 6, the number of the powder-particle nozzle and the gas nozzle which are most suitable in the case of the above-described angle is obtained.

(10) Since the gas nozzle 4 has a thin waist structure, the flow velocity of the carrier gas ejected from the gas nozzle 4 can be further accelerated.

(11) Since the cross-sectional area of the block member 6 with respect to the horizontal plane is larger at the lower portion than at the upper portion, the cross-sectional area of the block member 6 is reduced in the upper portion of the container remote from the granular body nozzle 3 and the gas nozzle 4, whereby the cross-sectional area of the block member 6 can be reduced. The space promotes the diffusion of the pulverized powder and granules and inhibits the re-agglomeration of the granules.

(12) The block member 6 is formed such that the cross-sectional area with respect to the horizontal plane becomes smaller as it goes upward from the predetermined height, so that the block member 6 is reduced at the upper portion of the container 2 far from the granular body nozzle 3 and the gas nozzle 4. The cross-sectional area by which the space can be increased, and the diffusion of the pulverized powder or granules is promoted, and the re-agglomeration of the granules is suppressed.

(13) In the position of the granular body nozzle 3 and the gas nozzle 4, the cross-sectional area of the block member 6 with respect to the horizontal plane is 1/6 or more and 1/3 or less of the sectional area of the container 2 with respect to the horizontal plane. In addition to determining the horizontal cross section of the block member 6, for example, if the horizontal cross section of the block member 6 is circular, the diameter of the circle is determined in consideration of the following.

That is, when the circular diameter of the horizontal cross section of the block member 6 is too small, the swirl flow path of the carrier gas or the like becomes large to weaken the rectifying effect. On the other hand, when the circular diameter of the horizontal section of the block member 6 is excessively large, the swirl flow path of the carrier gas or the like becomes small, and the powder particles and the carrier gas collide with the block member 6, thereby disturbing the inside of the container 2. The air flow and the wear of the block member 6 become remarkable. In view of the above, the most suitable diameter of the circular shape of the horizontal section of the block member 6 is determined as described above.

(14) Since the height of the block member 6 is one-half or less of the height of the discharge port 5, the block member 6 does not exist in the upper portion of the container remote from the powder/particle nozzle 3 and the gas nozzle 4, thereby promoting the crushing. The diffusion of the granules inhibits the re-agglomeration of the granules.

(15) The pulverizing apparatus 1 discharges the pulverized powder and granules downward toward the processing chamber 11, so that when the pulverized powder or granules are discharged, they are separated by gravity, and the ratio of re-agglomeration can be reduced.

In the above embodiment, the pulverizing apparatus 1 has one granule nozzle 3 and three gas nozzles 41 to 43, but the number of the granule nozzles is not limited to one, and may be two or more, and the number of gas nozzles It is not limited to three, and only one or more may be used.
