圖2為圖1之II-II截面圖。如圖2所示,粉粒體噴嘴3及氣體噴嘴4是以略等間隔地配置於水平截面為圓形之容器2的下部體21,本實施形態中,粉粒體噴嘴3設有1個,氣體噴嘴4設有3個(氣體噴嘴41~43)。而且,粉粒體噴嘴3及氣體噴嘴4以上面視角來看是在容器2內朝渦旋方向R噴射粉粒體及載氣。 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.
氣體噴嘴41~43在通過載氣之氣道(風洞)中,具有中心較細之細腰構造(中間細構造)41a~43a。氣體噴嘴41~43是朝相對於鄰接於容器2內之粉粒體及載氣之渦旋方向R之下游側之粉粒體噴嘴3或氣體噴嘴41~43的噴射方向具有正交方向分量的方向噴射載氣。再者,在此所謂「噴射方向」,是指噴嘴之中心線之延長線上的方向。 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.
具體而言,氣體噴嘴41之噴射方向A1是位於噴射部連結直線L11與切線L12所形成之角度θ1的範圍內,噴射部連結直線L11是連結氣體噴射部41b與鄰接於渦旋方向R之下游側之粉粒體噴嘴3之粉粒體噴射部(鄰接粉粒體噴 射部)3a,切線L12是從氣體噴射部41b往塊體構件6。其結果是,氣體噴嘴41之噴射方向A1對粉粒體噴嘴3之噴射方向B1具有正交方向分量。氣體噴嘴41宜以噴射方向A1會收斂在角度θ1之範圍內的方式,從噴射部連結直線L11朝向容器2之內部傾斜角度θ(例如5度左右)來噴射載氣。其中,本發明中,藉由使用載氣使粉粒體之間碰撞,促進粉粒體之粉碎,但從氣體噴嘴剛噴射載氣後,載氣之氣流很快,當中難以存在粉粒體。因此,角度θ宜設定為噴射方向A1與粉粒體噴嘴3之粉粒體噴射部3A相差距離D1(10mm左右)以上。 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.

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.
氣體噴嘴43之噴射方向A3是位於噴射部連結直線L31與從氣體噴射部43b往塊體構件6之切線L32形成之角度θ3之範圍內,且前述噴射部連結直線L31是連結氣體噴射 部43b與鄰接於渦旋方向R之下游側之氣體噴嘴41的氣體噴射部(鄰接氣體噴射部)41b。其結果是,氣體噴嘴43之噴射方向A3對氣體噴嘴41之噴射方向A1具有正交方向分量。氣體噴嘴43宜以噴射方向A3收斂在角度θ3之範圍內的方式,從噴射部連結直線L31朝向容器2之內部傾斜角度θ(例如5度左右,且該角度與噴射方向A1之傾斜角度大致相同)來噴射載氣。而且,角度θ宜設定為噴射方向A3與氣體噴嘴41之氣體噴射部41b相差距離D3(10mm左右)以上。 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.
與氣體噴嘴41~43同樣地,粉粒體噴嘴3之噴射方向B1位於噴射部連結直線L41與從粉粒體噴射部3a往塊體構件6之切線L42形成之角度θ4的範圍內,噴射部連結直線L41是連結粉粒體噴射部3a與鄰接於渦旋方向R之下游側之氣體噴嘴42的氣體噴射部(鄰接氣體噴射部)42b。其結果是,粉粒體噴嘴3之噴射方向B1對氣體噴嘴42之噴射方向A2具有正交方向分量。粉粒體噴嘴3宜以噴射方向B1收斂在角度θ4之範圍內的方式,從噴射部連結直線L41朝向容器2之內部傾斜角度θ(例如5度左右,且該角度與噴射方向A1之傾斜角度大略相同)來噴射粉粒體。而且,角度θ宜設定為噴射方向B1與氣體噴嘴42之氣體噴射部42b相差距離D4(10mm左右)以上。 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.
處理裝置10進行如下作動。 The processing device 10 performs the following operations.
粉碎裝置1中,粉粒體從粉粒體噴嘴3噴射到容器2內,載氣從氣體噴嘴4噴射到容器2內。再者,亦可從粉粒體噴嘴3混和粉粒體與載氣後噴射,以順利地進行粉粒體之 噴射。 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.
從氣體噴嘴41噴射之載氣與從粉粒體噴嘴3噴射之粉粒體碰撞,並且粉碎粉粒體。而且,從氣體噴嘴42噴射之載氣與從氣體噴嘴41噴射之載氣及從粉粒體噴嘴3噴射之粉粒體碰撞,並且進而粉碎粉粒體。而且,從氣體噴嘴43噴射之載氣與從氣體噴嘴41、42噴射之載氣及從粉粒體噴嘴3噴射之粉粒體碰撞,進而粉碎粉粒體。 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.
藉由從氣體噴嘴4噴射之載氣而粉碎的粉粒體與載氣一起渦旋於塊體構件6之周圍,進而被粉碎並朝向上方。而且,在沒有塊體構件6之高度以上,促進被粉碎之粉粒體的擴散,並且抑制粉粒體之再凝聚,粉粒體渦旋並且朝向上方。而且,粉粒體及載氣從設置於容器2之上部體22之上壁之中央部的排出口5排出。 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.
從排出口5排出之粉粒體及載氣通過連結於排出口5之連絡通路12,並且從處理室11之接收口11a往處理室11內向下排出。接收到處理室11粉粒體在處理室11中,進行預定處理,例如熱處理。 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.
根據前述構成之處理裝置10,可發揮如下效果。 According to the processing apparatus 10 of the above configuration, the following effects can be exhibited.
(1)由於朝對於鄰接於粉粒體及載氣之渦旋方向R之下游側之粉粒體噴嘴3或氣體噴嘴4的噴射方向具有正交方向分量的方向噴射載氣,因此可藉由噴射之載氣,而進一步粉碎粉粒體,降低無法再凝聚並且粉碎之粉粒體的比率。 (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)可藉由噴射之載氣進一步粉碎粉粒體,因 此可減低導入至容器2內之載氣量。 (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)藉由在容器2之中央部配置塊體構件6,可使容器2內之粉粒體及載氣之渦旋順利。進而,可在粉粒體不與載氣衝突之下減少從排出口5排出之比率。 (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)粉碎裝置1是藉由使載氣直接碰撞粉粒體而粉碎粉粒體之凝聚者。當使載氣直接碰撞塊體構件6時,容器內之氣流會亂掉,並且塊體構件6之耗損變明顯,因此噴射方向宜設定為從往塊體構件6之切線方向朝向容器2之外側。 (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. .
又,由於抑制粉粒體及載氣的速度會因為沿著容器內壁面7而衰減,因此粉粒體噴嘴3及氣體噴嘴4之方向從上面視角來看,宜為比噴射部連結直線更往容器2之中心傾斜。 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.
考慮到上述,藉由在噴射部連結直線與從氣體噴射部往塊體構件6切線形成之角度的範圍內噴射載氣,載氣以適當的角度碰撞粉粒體,可促進噴射之載氣進行粉粒體的粉碎。 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)由於容器2之水平截面具有圓形,因此在容器2內,可使粉粒體及載氣順利地渦旋。 (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)由於塊體構件6之水平截面具有圓形,因此在容器2內,可使粉粒體及載氣順利地在塊體構件6之周圍渦旋。 (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)由於在塊體構件6之上端部與容器2之上壁之間設有預定之間隙,因此可促進粉碎之粉粒體的擴散, 並且抑制粉粒體之再凝聚。 (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)由於氣體噴嘴4是從噴射部連結直線朝向容器之內部而在從5度開始θ1、θ2或θ3之角度的範圍內噴射載氣,因此載氣會以適當的角度碰撞到粉粒體,且可促進噴射之載氣進行之粉粒體的粉碎。 (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)粉粒體噴嘴3及氣體噴嘴4設有合計3~6個,因此為上述角度之情況下最適合的粉粒體噴嘴及氣體噴嘴之個數。 (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)由於氣體噴嘴4具有細腰構造,因此可更為加快從氣體噴嘴4噴射之載氣的流速。 (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)塊體構件6相對於水平面之截面積是下部比上部大,因此在遠離粉粒體噴嘴3及氣體噴嘴4之容器的上部,縮小塊體構件6之截面積,藉此可加大空間,促進被粉碎之粉粒體的擴散,抑制粉粒體之再凝聚。 (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)塊體構件6是形成為相對於水平面之截面積隨著從預定高度朝向上方而變小,因此在遠離粉粒體噴嘴3及氣體噴嘴4之容器2的上部,縮小塊體構件6之截面積,藉此可加大空間,並且促進被粉碎之粉粒體的擴散,並且抑制粉粒體之再凝聚。 (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)在粉粒體噴嘴3及氣體噴嘴4之位置中,塊體構件6之相對於水平面的截面積為容器2相對於水平面之截面積的1/6以上、1/3以下。除了確定塊體構件6之水平截面之外,例如,若塊體構件6之水平截面為圓形時,則考慮以下內容決定圓形之直徑。 (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.
即,當塊體構件6之水平截面的圓形直徑過小時,載氣等之渦旋流路變大而減弱整流效果。另一方面,當塊體構件6之水平截面的圓形直徑過大時,載氣等之渦旋流路會變小,粉粒體及載氣碰撞到塊體構件6,而擾亂容器2內之氣流,並且塊體構件6之摩耗變顯著。考慮到以上,塊體構件6之水平截面之圓形的最適合直徑是如上述而決定。 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)塊體構件6之高度為排出口5之高度之一半以下,因此在遠離粉粒體噴嘴3及氣體噴嘴4之容器的上部,不存在塊體構件6,藉此可促進被粉碎之粉粒體的擴散,抑制粉粒體之再凝聚。 (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)粉碎裝置1是將被粉碎之粉粒體朝處理室11向下排出,因此被粉碎之粉粒體在排出時,會因為重力而分離,並且可減少再凝聚之比例。 (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.
上述實施形態中,粉碎裝置1具有1個粉粒體噴嘴3與3個氣體噴嘴41~43,但粉粒體噴嘴之數目不限定1個,亦可為2個以上,又,氣體噴嘴之數目不限定3個,只要為1個以上即可。 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.

As shown in FIGS. 3 to 5, the number of the granular body nozzle 3 and the gas nozzle 4 can be appropriately adjusted in accordance with the size of the container 2 and the block member 6.
