The powdery material nozzle 3 is provided on the side wall of the lower body 21 of the container 2 so as to inject the powdered material into the container 2. The gas nozzle 4 is provided on the side wall of the lower body 21 of the vessel 2 and is adapted to inject a carrier gas into the vessel 2. The powder compact nozzle 3 and the gas nozzle 4 are located at the same height and are arranged at equal intervals in the circumferential direction on the side wall of the lower body 21. The outlet 5 is provided at the center of the upper wall of the upper body 22 of the container 2. The inner diameter of the particle nozzle 3 is slightly larger than the inner diameter of the gas nozzle 4 for spraying the powder.

A block member (6) is disposed at the center of the interior of the container (2). The lower member 61 of the block member 6 has a columnar shape and the upper member 62 of the upper member 62 has a conical trapezoidal shape. The upper surface of the lower body 61 coincides with the lower end surface of the upper body 62. As a result, the lower body 61 is larger in cross-sectional area with respect to the horizontal surface than the upper body 62. [ The cross-sectional area of the block member 6 with respect to the horizontal plane is formed to be smaller as it goes from the lower end face of the upper body 62 toward the upper portion. The height of the block member 6 is lower than the height of the lower body 21 of the container 2 and less than half the height of the discharge port 5. [ The height of the powdery material nozzle 3 and the gas nozzle 4 is positioned near the boundary between the lower body 61 and the upper body 62 of the block member 6. [

The cross sectional area of the lower member 61 of the block member 6 with respect to the horizontal plane at the positions of the powder nozzle 3 and the gas nozzle 4 is set such that the cross sectional area with respect to the horizontal plane of the lower member 21 of the container 2 1/6 or more, and is 1/3 or less.

The powder and the carrier gas injected from the powder nozzle 3 and the gas nozzle 4 are discharged from the discharge port 5 toward the upper part while turning around the block member 6. [ The communication passage 12 is connected at one end to the discharge port 5 so that the powder and the carrier gas discharged to the upper portion from the discharge port 5 are discharged downward from the upper part toward the treatment chamber 11, And a bent portion 12a bent toward the portion. The treatment chamber 11 has an acceptance port 11a connected to the other end of the communication passage 12 in the upper wall portion.

Fig. 2 is a cross-sectional view taken along the line II-II in Fig. As shown in Fig. 2, the particle nozzles 3 and the gas nozzles 4 are arranged at substantially equal intervals with respect to the lower body 21 of the container 2 having a circular cross section in the horizontal section, One gas nozzle 3 and three gas nozzles 4 (gas nozzles 41 to 43) are provided. The powdered matter nozzle 3 and the gas nozzle 4 are configured to inject the powdered particles and the carrier gas in the swirling direction R in the container 2 when viewed from above.

The gas nozzles 41 to 43 are provided with Laval structures (constricted structures) 41a to 43a whose centers are constricted in the air passage (wind tunnel) through which the carrier gas passes. The gas nozzles 41 to 43 are arranged so as to be orthogonal to the spray direction of the powdery material nozzle 3 or the gas nozzles 41 to 43 adjacent to the powdery material in the container 2 and the downstream side of the pouring direction R of the carrier gas. The carrier gas is injected in the direction having the direction component. Here, the " injection direction " means the direction on the extension line of the center line of the nozzle.

More specifically, the injection direction A1 of the gas nozzle 41 is set so that the gas spraying portion 41b and the powder spraying portion of the powder spray nozzle 3 adjacent to the downstream side in the swirling direction R 1 formed by the jetting section connecting straight line L11 and the tangential line L12 from the gas jetting section 41b to the block member 6 for binding the upper and lower sections 3a. As a result, the injection direction A1 of the gas nozzle 41 has an orthogonal direction component with respect to the injection direction B1 of the particle nozzle 3. The gas nozzle 41 is inclined at an angle? From the jetting section connecting straight line L11 toward the interior of the container 2 so that the jetting direction A1 is within the range of the angle? About 5 degrees), it is preferable to inject the carrier gas. Here, in the present invention, the pulverization of the powder particles is promoted by colliding the powder particles with the carrier gas. However, immediately after the carrier gas is injected from the gas nozzle, the air current of the carrier gas is fast, it's difficult. Therefore, it is preferable that the angle? Is set so that the spraying direction A1 is spaced from the powder compact spraying unit 3a of the powder spray nozzle 3 by a distance D1 (about 10 mm) or more.

The injection direction A2 of the gas nozzle 42 is a direction in which the gas injection portion 42b of the gas nozzle 43 and the gas injection portion 43b of the gas nozzle 43 adjacent to the downstream side in the swing direction R 2 formed by the jet line connecting straight line L21 and the tangential line L22 from the gas jetting section 42b to the block member 6. The angle? As a result, the ejecting direction A2 of the gas nozzle 42 has an orthogonal direction component with respect to the ejecting direction A3 of the gas nozzle 43. The gas nozzle 42 is inclined at an angle? From the jetting portion connecting straight line L21 toward the inside of the container 2 such that the jetting direction A2 is within the range of the angle 2 , This angle is about the same as the inclination angle of the injection direction A1), it is preferable to inject the carrier gas. It is preferable that the angle? Is set so that the ejecting direction A2 is spaced from the gas ejecting portion 43b of the gas nozzle 43 by a distance D2 (about 10 mm) or more.

The jetting direction A3 of the gas nozzle 43 is a direction in which the gas jetting portion 43b and the gas jetting portion (adjacent gas jetting portion) 41b of the gas nozzle 41 adjacent to the downstream side in the turning direction R 3 formed by the jet line connecting straight line L31 and the tangent line L32 from the gas jetting portion 43b to the block member 6. [ 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 is inclined at an angle? From the jetting section connecting straight line L31 toward the inside of the container 2 so that the jetting direction A3 is within the range of the angle? 3 , This angle is about the same as the inclination angle of the injection direction A1), it is preferable to inject the carrier gas. It is preferable that the angle? Is set so that the ejecting direction A3 is spaced from the gas ejecting portion 41b of the gas nozzle 41 by a distance D3 (about 10 mm) or more.

The injection direction B1 of the powder nozzle 3 is the same as that of the gas nozzles 41 to 43 in the gas nozzle 42 adjacent to the powder particle injecting section 3a and downstream in the turning direction R. [ Is set to be within a range of an angle? 4 formed by a jetting section connecting straight line L41 that binds a quadrant (adjacent gas jetting section) 42b and a tangent line L42 from the powder compact injecting section 3a to the block member 6 . As a result, the spray direction B1 of the particle nozzle 3 has an orthogonal direction component with respect to the spray direction A2 of the gas nozzle 42. [ The particle nozzle 3 is inclined from the jetting section connecting straight line L41 by the angle? Toward the inside of the container 2 such that the jetting direction B1 is within the range of the angle? For example, about 5 degrees, and this angle is almost the same as the inclination angle of the spray direction A1), it is preferable to spray the powder. It is preferable that the angle? Is set so that the ejecting direction B1 is spaced from the gas ejecting portion 42b of the gas nozzle 42 by a distance D4 (about 10 mm) or more.

The processing apparatus 10 is designed to operate as follows.

In the grinding apparatus 1, the powder is injected into the container 2 from the powder-form nozzle 3, and the carrier gas is injected into the container 2 from the gas nozzle 4. Further, the powdered material and the carrier gas may be mixed and injected from the powdered material nozzle 3 so that the powdered material can be injected smoothly.

The carrier gas injected from the gas nozzle 41 collides with the powder and granules injected from the powder and granule nozzle 3, thereby pulverizing the powder and granules. The carrier gas injected from the gas nozzle 42 collides with the carrier gas injected from the gas nozzle 41 and the powder mixture injected from the powder nozzle 3 to further pulverize the powder. The carrier gas injected from the gas nozzles 43 collides with the carrier gas injected from the gas nozzles 41 and 42 and the granular material injected from the granular nozzle 3 to further pulverize the granular material .

The powdered or granular material pulverized by the carrier gas injected from the gas nozzle 4 turns around the block member 6 together with the carrier gas and is further pulverized and directed to the upper portion. At the height above the level at which the block member 6 disappears, diffusion of the pulverized powder particles is promoted, and the re-aggregation of the powder particles is suppressed, so that the powder particles are swirled and directed further upward. The powder and the carrier gas are discharged from the discharge port 5 provided at the center of the upper wall of the upper body 22 of the container 2.

The powder and the carrier gas discharged from the discharge port 5 pass through the communication passage 12 connected to the discharge port 5 and are discharged downward into the treatment chamber 11 from the receiving port 11a of the treatment chamber 11. The powder that has entered the treatment chamber 11 is subjected to a predetermined treatment, for example, heat treatment, in the treatment chamber 11.

According to the processing apparatus 10 configured as described above, the following effects can be obtained.

(1) Since the carrier gas is injected in the direction having an orthogonal direction component with respect to the spray direction of the powdery matter nozzle 3 or the gas nozzle 4 adjacent to the powdery matter and the downstream side of the turning direction R of the carrier gas, The powdered carrier can be further pulverized by the carrier gas, and the proportion of the re-pulverized or unfrozen pulverized material can be reduced.

(2) Since the powdered material can be further pulverized by the injected carrier gas, the amount of the carrier gas introduced into the container 2 can be reduced.

(3) By arranging the block member 6 at the center of the container 2, it is possible to smooth the turning of the powder and the carrier gas in the container 2. [ Also, the ratio of the powder discharged from the discharge port 5 without colliding with the carrier gas can be reduced.

(4) The pulverizing apparatus 1 pulverizes the coagulation of the powder particles by causing the carrier gas to collide directly with the powder particles. The flow in the container is disturbed and the abrasion of the block member 6 becomes remarkable so that the injection direction is shorter than the tangential direction of the block member 6 in the container (6) 2).

In addition, since the speeds of the powdered particles and the carrier gas are suppressed from being attenuated by moving along the inner wall surface 7, the directions of the powdered matter nozzle 3 and the gas nozzle 4 are set so that, It is preferable to make inclination toward the center of the container 2 rather than the quadric connecting line.

Considering the above, by injecting the carrier gas within the range of the jet line connecting line and the angle formed by the tangent line to the block member 6 from the gas jetting section, the carrier gas collides with the powder compact at an appropriate angle, It is possible to promote the pulverization of the powdered material by the gas.

(5) Since the container 2 has a circular cross section in the horizontal section, it is possible to smoothly rotate the powder and the carrier gas in the container 2. [

(6) Since the horizontal cross section of the block member 6 has a circular shape, it is possible to smoothly rotate the powder and the carrier gas around the block member 6 in the container 2.

(7) Since a predetermined clearance is provided between the upper end of the block member 6 and the upper wall of the container 2, the diffusion of the pulverized powder particles can be promoted and the re-aggregation of the powder particles can be suppressed.

(8) Since the gas nozzle 4 is designed to inject the carrier gas in an angular range of? 1,? 2 or? 3 at 5 degrees from the connecting straight line of the jet part toward the inside of the vessel, And it is possible to promote the pulverization of the powder particles by the injected carrier gas.

(9) Since the number of the powder nozzles 3 and the number of the gas nozzles 4 are three to six in total, the number of the powder nozzles and the number of the gas nozzles are optimal for the above-mentioned angle.

(10) Since the gas nozzle 4 has the Laval structure, the flow rate of the carrier gas injected from the gas nozzle 4 can be made faster.

(11) Since the cross-sectional area of the block member 6 with respect to the horizontal plane is larger than that of the upper portion, the cross-sectional area of the block member 6 at the upper portion of the vessel remote from the gas nozzle 4, The space is widened, the diffusion of the pulverized powder particles is promoted, and the re-aggregation of the powder particles can be suppressed.

(12) Since the cross-sectional area of the block member 6 with respect to the horizontal plane is made smaller as it goes from the predetermined height to the upper portion, the block member 6 is formed at the upper part of the container 2 remote from the particle nozzle 3 and the gas nozzle 4 By reducing the cross-sectional area of the block member 6, the space is widened, the diffusion of the pulverized powder particles is promoted, and the re-aggregation of the powder particles can be suppressed.

(13) The sectional area of the block member 6 with respect to the horizontal plane at the position of the particle nozzle 3 and the gas nozzle 4 is not less than 1/6 of the sectional area with respect to the horizontal plane of the container 2, 3 or less. In determining the horizontal cross section of the block member 6, for example, when the horizontal cross section of the block member 6 is circular, the diameter of the circle is determined in consideration of the following contents.

That is, if the circular diameter of the horizontal cross section of the block member 6 is too small, the swirling flow path of the carrier gas or the like becomes large, and the rectifying effect becomes weak. On the other hand, if the circular diameter of the horizontal cross section of the block member 6 is too large, the swirling flow path of the carrier gas or the like becomes small and the powder and the carrier gas collide with the block member 6, The abrasion of the block member 6 becomes remarkable. In consideration of the above, the optimal diameter of the circular section of the horizontal section of the block member 6 is determined as described above.

(14) Since the height of the block member 6 is less than half the height of the discharge port 5, the block member 6 is not present at the upper part of the vessel remote from the powder nozzle 3 and the gas nozzle 4 , The diffusion of the pulverized powder particles can be promoted, and the re-aggregation of the powder particles can be suppressed.

(15) Since the pulverizing apparatus 1 is designed to discharge the pulverized pulverized material downward toward the treatment chamber 11, it is possible to reduce the rate of re-coagulation by separating by gravity when the pulverized pulverized material is discharged.

In the above embodiment, the grinding apparatus 1 is provided with one particle nozzle 3 and three gas nozzles 41 to 43, but the number of the particle nozzles is not limited to one, but two or more Further, the number of gas nozzles is not limited to three, but may be one or more.
