Description of the Invention: [Technical Field to Which the Invention Is Applicable] The present invention relates to the removal of a powder of a fine powder from a fine powder. [Prior Art] Patent Documents 1 and 2 disclose an example of a mechanism for removing fine powder from powder or granules. This mechanism is provided with a supply pipe above the cylindrical casing, and a suction pipe is arranged in the casing: a casing is formed in the casing to form a mesh-shaped cylinder. Use a hose or piping to form a supply pipe connection (powder-like) into the material container, use the rape plant tube; = attract the official connection on the induced draft fan. The mixed gas of the age and the air (the example of the transporting gas of the powder and granules) flows from the supply pipe, and rotates along the inner wall-side of the screening program, and the centrifugal force generated by the spiral flow is used as the second particle. The powder adhered to the powder (micro powder - for example) and the particles are separated from the inside and outside of the side wall of the screening program. The powdery air is discharged from the suction tube. The powder after the powder is dropped from the opening at the lower end of the screening program. Patent Document 2 proposes a technical solution in which the air suction port as the suction pipe is formed to be larger than the powder granules as the supply f, and the (four) of the sleeve is set to be compared with The f center _ granule suction π is disposed at a larger distance, and the gas flow of the mixed gas flowing along the inner wall of the screening program is formed into a spiral shape, and the residence time of the mixed gas on the screening surface is prolonged. In the screening program, a long hole-shaped screening program hole is arranged in the gripping direction of the mixed gas flow (uncontrolled "free airflow 4 201215460") which flows spirally along the inner wall of the inspection program. It is possible to separate fibrous or rod-shaped objects from the powder and granules. Patent Document 1: Japanese Laid-Open Patent Publication No. Hei. No. Hei. No. Hei. No. 2009-273969. When the retention time on the surface of the program (5), the removal efficiency of the fine powder can be improved. However, in the technique disclosed in Patent Document 2, there is a problem that the shape of the device is restricted. SUMMARY OF THE INVENTION An object of the present invention is to provide a fine powder removing apparatus which can extend the residence time of a mixed gas on a screening surface and can freely design the shape of the apparatus. In order to achieve the above object, a fine powder removing device according to a first aspect of the present invention includes an inner cylinder and an outer cylinder disposed outside the inner cylinder. In the side wall of the inner cylinder, at least a portion of a portion overlapping the side wall of the outer cylinder along the axial direction of the central axis of the inner cylinder is formed as a porous screening program, and a powdery body is disposed in the inner cylinder The transport gas and the inflow port for the mixed gas of the powder and granules are disposed, and at the same time, the transport gas passing through the sieve hole and the fine powder contained in the mixed gas flowing into the inner cylinder are disposed to flow out of the outer cylinder together a flow outlet, wherein the screening program is provided with a free air flow of a mixed gas that spirally flows along the inner wall of the screening program, closer to the central axis of the inner cylinder than the direction of the free air flow A guide that guides the direction of the right angle to one of the directions at right angles to the central axis of the inner cylinder. 201215460 The second secret system provides a micro-powder removal device in which the mixing: =: T guides the helical flow along the inner wall of the screening program, providing a third aspect in a direction at right angles to the central axis of the inner cylinder. Micropowder: The outer cylinder of the outside of the cylinder. At least one adjacent to the portion of the side wall of the inner cylinder that overlaps the side wall of the outer cylinder in the axial direction of the inner cylinder becomes a porous screening program', and in the (four), a milk-feeding body for the powder and granules is disposed The mixed gas of the powder or granule flows into the human π, and at the same time, the fine powder contained in the mixed gas flowing into the inner cylinder (10) is turned on, and the conveying gas of the program hole flows toward the outflow of the outer cylinder. The second inspection program hole is formed as a long hole in the longitudinal direction in the direction of the center surface of the inner cylinder. And using the fourth aspect to provide a micro-fan device, wherein the detection program described in any of the inventions of the first to the <> The shape of the wrong vertical line becomes narrower and narrower. If the first aspect is adopted, a guide is disposed on the screening program, and the free airflow of the mixed gas flowing spirally along the inner wall of the inspection program is used to compare the free airflow of the mixed gas flowing along the inner wall of the inspection program from the self-domain flow. The direction is closer to a direction at a right angle to the central axis of the inner cylinder to a direction at a right angle to the central axis of the inner cylinder, so that the airflow of the mixed gas of the detector (four) can be formed into a so-called guide (four). Spiral. Therefore, it is possible to provide a fine powder removing device which can freely design the shape of the device and can prolong the retention of the mixed gas on the Korean test surface. 6 201215460=If the second aspect is adopted, a guide is provided on the screening program, by means of which the free airflow of the mixed gas flowing spirally along the inner wall of the screening program can be guided to the inner cylinder Since the center axis is in the direction perpendicular to the direction, the airflow of the mixed gas in the screening program can be formed into a spiral shape having a smaller guide angle. Thereby, the residence time of the mixed gas on the screening surface can be further extended. If the third aspect is adopted, the screening program hole is formed as a long hole in the longitudinal direction at a right angle to the center of the inner bay, so that the centrifugal force acts on the mixed gas flowing spirally along the inner wall of the screening program, so the mixed gas The powder or granules in the screening program move along the edge of the length of the screening program hole, and the free airflow of the mixed gas flowing spirally along the inner wall of the screening program is guided to the length of the screening program hole. In this way, the screening program hole functions as a guide that guides the free airflow of the mixed gas flowing spirally along the inner wall of the screening program at a right angle to the central axis of the inner cylinder, thereby enabling mixing in the screening program. The flow of the gas is formed into a spiral flow having a small lead angle, and the flow of the mixed gas in the screening program can be formed into a spiral having a smaller lead angle, so that the mixed gas can be further extended on the screening surface. The length of stay. Therefore, it is possible to provide a fine powder removing device which is free from the shape of the juice device and which can prolong the residence time of the mixed gas on the screening surface.

，如第1圖、第6圖、第7圖（C)所示，流出管70具備進入内 筒10側壁與外筒20側壁之間的環狀空間20A的管側壁73,因 此在環狀空間20A作螺旋狀流動的空氣1之氣流8變強，最終 ，沿著篩檢程式3 0内壁作螺旋狀流動的混合氣體3之氣流6 也變強，能夠提高去除微粉4的效率。 如上所述，如果採用本實施例，則能夠得到的效果如 下所述。 在篩檢程式30、300設置導向器31、32，利用該導向器 31、32，將沿著篩檢程式30、300内壁作螺旋狀流動的混合 氣體3之自由氣流5,從相較於該自由氣流5的方向更接近於 與内筒10中心軸11呈直角的方向到與内筒10中心軸11呈直 角的方向的一方向引導，這樣能使篩檢程式30、300内的混 合氣體3之自由氣流5形成導程角小的螺旋狀。從而能夠自 由設計裝置的形狀，且能夠延長混合氣體3在篩檢程式面上 的滯留時間。 篩檢程式30、300上設置導向器31、32，利用該導向器 31、32，將沿著篩檢程式30、300内壁作螺旋狀流動的混合 氣體3之自由氣流5，朝向與内筒10的中心軸11呈直角的方 向引導，能夠使篩檢程式30、300内的混合氣體3之自由氣 流5形成導程角更小的螺旋狀氣流。從而能夠使混合氣體3 在篩檢程式面上的滯留時間進一步延長。 篩檢程式孔31形成為長度方向在與内筒10的中心軸11

如第14圖、第π圖、第18圖（八）、第以圖⑺)所示，中心 筒100將其上端裝卸自如地固定於上蓋5〇的内表面，從上蓋 24 201215460 50的内表面同軸插人内筒1G的内侧配置，具有與内筒_ 上筒部12並行的圓筒部101、與篩撿程式3〇的側壁並行的圓 臺部102、以及圓臺部102侧的封閉端部1〇3，封閉端部1〇3 配置於_檢程式30的上方開口與下方開口之間，將封閉端 部103上方的柱狀空間ι〇Α形成為環狀空間1〇Β。通過流入 管60,從内筒10的上筒部12侧壁沿切線方向流入的混;氣 體3,沿著内筒10的上筒部12内壁一邊旋轉—邊下降，進入 篩檢程式30，沿著篩檢程式3〇内壁一邊旋轉—邊下降，那 時的旋轉内徑由中心筒100的側壁限制，混合氣體3容易沿 篩檢程式30内壁作螺旋狀流動。 ° 如第14圖、第17圖、第18圖（Β)所示，筛檢程式蓋u〇 ，作為篩檢程式孔31抑制從篩檢程式3〇侧壁内侧向外側流 出的空氣1流量之通氣抑制手段，設置於外筒2〇側壁與筛檢 程式30側壁之間。篩檢程式蓋11〇為筒狀，將設置於上方開 口的凸緣111夾在凸緣12a與凸緣82之間，與内筒1〇同軸地 配置於外筒20侧壁與筛檢程式3〇侧壁之間，至少覆蓋筛檢 程式30側壁的上方。又，可以利用篩檢程式蓋11〇的側壁長 度（覆蓋篩檢程式30的侧壁面積）、直徑（篩檢程式蓋11〇 側壁與筛檢程式30侧壁之間的間隔）、形狀（有無孔、開 口率的夕少），使由篩檢程式孔31從篩檢程式3〇側壁内側 流向外侧的空氣1流量最佳化，在混合氣體3沿著篩檢程式 30内壁作螺旋狀流動期間，確保篩檢程式3〇内需要的空氣工 流量，以避免該氣流6速度降低。也就是說，避免沿著篩檢 程式30内壁螺旋狀流動的混合氣體3之氣流6產生的離心力 25 201215460 減小，防止微粉4的去除效率下降。 另外’本實施例中流出管70，以從内筒1〇的中心軸^ 到流入管60的中心為止的半徑為半徑，以内筒1〇的中心轴 11為中心使其旋轉時，從内筒10的中心軸11的軸向上來看 ，流出管70與流入管60並不重疊’沿著篩檢程式3〇内壁作 螺旋狀流動的混合氣體3之氣流6 ’與在内筒1 〇側壁（|帛檢 程式30的側壁與下筒部13的侧壁）與外筒2〇側壁（上筒部 21的側壁與下筒部2 2的側壁）之間作螺旋狀流動的混合了 微粉4的空氣1之氣流8，在相同的方向上旋轉，但是透過將 流出管70與流入管60重疊設置’可以使兩股氣流6、8的旋 轉方向相反。在此，與沿著篩檢程式30内壁作螺旋狀流動 的混合氣體3之氣流6旋轉方向相反’且在内筒1〇侧壁（篩 檢程式30的侧壁與下筒部13的侧壁）與外筒2〇側壁（上筒 部21的側壁與下筒部22的侧壁）之間作螺旋狀流動的混合 了微粉4的空氣1之氣流8，形成抑制由篩檢程式孔31從篩檢 程式30側壁内側向外側流出的空氣1流量的空氣門，因此可 以作為取代篩檢程式蓋11〇的通氣抑制手段使用。 如第14圖、第15圖所示，第2流入管從内筒1〇側壁 使發生旋轉氣流用的氣體流入，借助於該氣體，形成與沿 著篩檢程式30内壁作螺旋狀流動的混合氣體3之氣流6旋轉 方向相同的旋轉氣流9 (參照第17圖、第18圖(〇)，使從 流入管60流入的空氣1 (粉粒體的輪送氣體）的一部分la從 内苟1〇的下畸部13侧壁沿切線方向流入。該第2流入管120 為直管，貫通外筒20的下筒部22側壁，第2流入管12〇的入 26 201215460 口 121形成為圓形’在外筒20的下方外側形成開口。第2流 入管120的出口 122形成為矩形，該出口 122沿著内筒1〇的下 筒部13侧壁開口。另外’在内筒1 〇的中心軸11的軸方向的 第2流入管120的位置只要是在流入管60下方即可。 如第16圖所示，在連接貯存槽92與流入管60的輸送配 管123中途設置Y字形分叉管124,利用該Y字形分叉管124 將從輸送配管123分叉出的分叉配管126連接於第2流入管 120，形成使顆粒2的配管輸送用的空氣1的一部分1 a從第2 流入管120流入的結構。分叉配管126上設置空氣筛檢程式 (只使空氣la通過）127和流量調整閥128。 流量調整閥128是使從第2流入管120流入的空氣以流 量相較於從流入管60流入的空氣1流量少的調整閥，利用γ 字形分叉管124的Y字角度125，能夠改變從貯存槽92連接 埠流往流入管6 0連接埠的流量與流往第2流入管12 〇連接埤_ 的流量’因此Y字形分叉管124也能夠作為使從第2流入管 120流入的空氣1 a流量相較於從流入管60流入的空氣1流量 少的流量調整手段使用。 如第17圖、第18圖（C)所示，空氣la通過第2流入管12〇 ，從該處的侧壁沿切線方向流入内筒10的下筒部13内，形 成與一邊沿著内筒10的下筒部13内壁旋轉一邊沿著筛檢程 式30内壁作螺旋狀流動的混合氣體3之氣流6旋轉方向相同 的旋轉氣流9。該旋轉氣流9將沿著篩檢程式30内壁作螺旋 狀流動的混合氣體3之氣流6捲入’使該混合氣體3之氣流6 接近旋流，形成導程角更小的強螺旋狀，因此在篩檢程式 27 201215460 30内，混合氣體3能夠充分旋轉，可以延長在篩檢程式面上 的滯留時間，而可以提高微粉去除效率。又，内筒1〇的側 壁中，在内筒10的中心軸1丨的軸方向上與第2流入管12〇重 疊的部分’為了阻斷通氣而利用内筒1〇的下筒部13侧壁形 成無孔的通氣阻斷部，使從第2流入管120流入的空氣1&不 會從柱狀空間10A下方外壁（内筒1〇的下筒部13的侧壁）洩 漏到位於其周圍的環狀空間2〇A下方，而能夠在柱狀空間 10A下方（内筒10的下筒部13内）形成強旋轉氣流9，因此 沿著_檢程式3 0内壁作螺旋狀流動的混合氣體3之氣流6形 成導程角更小的螺旋狀。 在本實施例中，對第2流入管120提供空氣1 (輸送粉粒 體的氣體）的一部分la，但是也可以從產生旋轉氣流用的 鼓風機’利用顆粒2的配管輸送系統以外的配管系統壓送產 生旋轉氣流用的空氣。作為產生旋轉氣流用的氣體，也可 以提供氮氣或二氧化碳等空氣以外的氣體。第2流入管120 也可以使產生旋轉氣流用的氣體從篩檢程式3 〇侧壁沿切線 方向流入。 實施例3 下面參照第19圖〜第24圖對實施例3之微粉去除裝置 進行說明。第19圖為實施例3之微粉去除裝置的整體結構示 意圖，第20圖為實施例3之微粉去除裝置的外觀示意圖，（ A)為前視圖’

的至少一部分’同時是用於從流入内筒140内的混合氣體3 (參照第22圖、第23圖）巾的塑膠樹脂顆粒2 (粉粒體之〜 例）中將微粉4分離到内筒14〇侧壁外側的部件，内筒14〇的 中心轴141為錯垂線時，形成向鉛垂方向下方越來越狹窄的 形狀的倒圓椎梯形，在該侧壁（侧面）的整個面上，呈鑛 齒狀排列設置只使混合氣體3中的空ai和微粉4通過（不使 顆粒2通過）的複數個篩檢程式孔⑶。該_檢程式別的侧 壁利用打孔金屬板構成。 各4檢程式孔1M具有與實施例】、2的筛檢程式孔叫目 同的結齡功能。作為將沿著篩檢程式1糊壁（筛檢程式 面）作累旋狀机動的混合氣體3之自由Ha (參照$24 29 201215460 圖），引向内筒140的中心軸141的直角方向（内筒14〇的中 心轴141處於錯垂線上時是引向水平方向）用的導向手段， 形成為長度方向垂直於内筒140的中心軸141的直角方向上 的長孔。又，各篩檢程式孔131，作為設置於篩檢程式13〇 的導向器，即將沿著篩檢程式丨3〇内壁作螺旋狀流動的混合 氣體3之自由氣流5A’從相較於該自由氣流的方向更接近内 筒140的中心軸141的直角的方向引導到於内筒14〇的中心 軸141的直角方向的角度區域0之一方向的導向器，形成為 長度方向在内筒140的中心軸141的直角方向上而能夠將沿 筛檢程式130内壁作螺旋狀流動的混合氣體3之自由氣流5A 向垂直於内筒140的中心軸141的直角方向引導的長孔。 回到第19圖、第2〇圖，内筒140是在其中心軸141為鉛 垂線時，沿著鉛垂方向越向下越狹窄且由上部、中部、下 部三部分構成的大圓椎梯形’上方由篩檢程式130構成，中 部和下方分別由圓椎梯形的中筒部位142和下筒部143構成 。外筒150具備直徑大致相同的圓筒形的上筒部151和下筒 部152構成的兩部分結構，下筒部152具備底板152a。這些 同軸配置的内筒140和外筒150中，内筒14〇在台板16〇上垂 直暨立’外筒150配置於内筒14〇的篩檢程式130與中筒部 142的周圍，使内筒140的下筒部143從底板152a的中央部向 下方突出，大致處於相同高度上的内筒14〇的上方開口（篩 檢程式130的上方開口）與外筒15〇的上方開口（上筒部151 的上方開口）用上蓋170關閉。 從外筒150的底板152a向下方突出的内筒140下方（下 201215460 筒部143)侧壁上，設置使混合氣體3從該處沿切線方向流 入内筒140内用的流入口、即流入管18〇。該流入管18〇為直 管，流入管180的入口 181形成為圓形，出口182形成為圓形 (有時可為矩形），該出口 182沿著内筒14〇下方侧壁開口 (參照第23圖（C))。 外筒150的側壁中，在内筒14〇的中心軸141的軸向上與

space 1A), The inner wall of the lower tubular portion 13 of the inner cylinder 10 is rotated while being lowered. Arriving at the lower opening of the lower tubular portion 13 of the inner cylinder 10, That is, the discharge port 13a, From this, the raw material supply hopper 91 of the molding machine 90 is discharged. of course, Along the inner wall of the screening process 30, while rotating, while descending, Passing through the screening program hole 31, 31 〇 of dust and plastic resin fragments, etc., are also removed as foreign matter together with the fine powder 4. such, The fine powder removing device of the present embodiment and the fine powder removing device of the reference example are capable of continuously processing the particles 2, Foreign matter such as fine powder 4 is removed from the particles 2. Next, the action of the screening program hole 31 of this embodiment will be described. As shown in Figure 8, The screening program hole 31 provided on the side wall of the screening program 30 shown in Fig. 9 is a long hole whose longitudinal direction is at a right angle to the central axis 11 of the inner cylinder 10. on the other hand, Spiral flow along the inner wall of the screening program 17 201215460 (4) Μ (4). therefore, Riding the program Kongzhou 吏 The particles 2 in the mixed gas 3 are along the upper and lower sides 3a of the length of the screening program hole 31, 3 turns, And the free airflow 5 of the mixed gas 3 flowing in a spiral along the program-wall is directed to the length of the inspection hole 31, That is, it is at a right angle to the inner cylinder_central shaft 11, As shown in Figure 6, As shown in Fig. 12, the free airflow 5 of the mixed gas 3 in the screening program 3G is converted into a swirling control airflow 6 which is smaller than the lead angle. With this, The residence time of the mixed gas 3 on the screening surface can be made longer than that of the free gas (10). The removal efficiency of the fine powder 4 can be improved. Here, the θ teacher checks the screening program hole 31 set on the pm μ training point, As long as the mixing center axis u of the ϊ_program_wall spirally flows at a right angle U, the flow direction is slightly closer to the long hole of the inner cylinder 10, It is possible to compare the mixing time in the screening program 30 with the control time of the _ small control airflow white i ★ D rolling body 3 on the screening surface; ^The residence time of the machine 5 is long', but is disposed in the angular direction 2 hole 31 on the side wall of the inspection program 30, It is a long hole whose length direction is straight white i1 with respect to the central axis π of the inner cylinder 10, so that the =5 of the mixed gas 3 in the screening program 30 can be converted into a control airflow having a smaller lead angle. It is possible to make the residence time of the mixed helium on the 4 test surface longer than that of the free air flow 5. in, , As shown in Figure 8, In the side wall of the inspection program 30, When the shaft 11 of the inner cylinder 10 is in the "line direction, The shape of the secret (four) in the vertical direction below the 'inverted cone trapezoid, In the screening process 201215460 hole 31 provided on the side wall of the screening program 30, The lower side 31b in the longitudinal direction is closer to the central axis 11 of the inner cylinder 10 than the upper side 3la in a size close to ^, The probability that the particles 2 are in contact with the lower side 31b of the screening program hole 31 increases. The guiding function of the screening program hole 31 can be effectively utilized. Next, a modification of the guide of the fine powder removing device of the present embodiment will be described. As shown in Figure 10, Replace the screening program hole 31, In the inner wall of the Korean inspection program, a plurality of projections 32 having a longitudinal direction in a direction perpendicular to the central axis of the inner cylinder 10 are arranged in a staggered manner. Same as the screening program hole 31, The guides ' provided on the screening program 30 can serve as the free airflow 5 of the mixed gas 3 which will spirally flow along the inner wall of the screening program 3, The guide is guided from a direction which is closer to a direction perpendicular to the central axis U of the inner cylinder 10 than the direction of the free air flow to a direction angular range of 0 in a direction perpendicular to the central axis 11 of the inner cylinder 1 . The protrusion 32 is made of metal, a rod-shaped member made of a plastic resin wire, A plate member (blade) composed of a plate material can be used. Set the protrusion 32 (4) to scream ', so that the Korean reference micro-powder removal device can be installed on the side wall, including a circular program. That is to say, the side wall is made of a metal mesh (4), and the current (4) screening program is used. At this time, the aperture ratio on the side of the screening program does not decrease significantly. The projections 32 are arranged on the inner wall of the screening program at a much wider interval than the (4) inspection hole 31. also, Next, other modifications of the guide of the fine powder removing device of the present embodiment will be corrected. As shown in Figure U, Screening lion, It is included in the longitudinal direction of the central axis 11 of the inner cylinder 1G in the longitudinal direction (the horizontal direction when the central axis η of the inner cylinder 1 is on the wrong line) (long hole (i-screen 201215460 program hole) 501 formed a range of 500A, And in a lower portion in the axial direction closer to the central axis 11 of the inner cylinder 10 than the range 5〇〇A (the lower portion of the inner cylinder 1〇 is on the wrong line, which is the lower portion in the vertical direction) The second long hole is guided from a direction in which the free air flow 5 of the mixed gas 3 is closer to a direction perpendicular to the central axis π of the inner cylinder 1 to a direction which is not perpendicular to the central axis 11 of the inner cylinder 10 The range 500B formed by the (second screening program hole) 502, among them , The first long hole 501 and the second long hole 502 are both provided as guides in the screening program 5〇〇. Do not use the screening program for setting the screening hole (guide) 31, The screening program 3 of the protrusion (guide) 32 is set, Instead, use this screening program 500. Here, the length direction of the second long hole 502 formed in the range 500B of the screening program 500 is Preferably, it is from the upper portion to the lower portion of the central axis 11 of the inner cylinder 1〇, The inclination angle is gradually increased from the direction perpendicular to the central axis 11 of the inner cylinder 10. under these circumstances, The inclination angle of each second long hole 502, It is possible to continuously increase from the upper portion to the lower portion of the central axis 11 of the inner cylinder 10 in the axial direction. It can also be increased by area unit (A to 1 area in the figure). also, In the screening program 5, The first long hole 501 may or may not be included. and also, As a guide placed on the screening program, In addition to using the screening program hole 31 of the side wall of the screening program, 501 and 502, Outside the protrusion 32 protruding from the inner wall of the screening program, It is also possible to use a groove on the inner wall of the screening program. The longitudinal direction thereof is a right angle direction of the central axis 11 of the inner cylinder 10, Or, the free air flow 5 from the mixed gas 3 is closer to a direction perpendicular to the central axis 11 of the inner cylinder 1 to a direction which is not at right angles to the central axis u of the inner cylinder 1 . here, Free airflow in the fine powder removal device of the set guide, 201215460 In the case where the guide passes through the side wall of the screening program, Except for the screening program hole, the minimum diameter of the guide hole is formed (the upper side 31a is spaced from the lower side 3lb, Refer to Figure 8 for a straight hole other than a straight hole. Including the aperture ratio of the side wall of the screening program, For the same structure, a gas flow of a mixed gas when the fine powder removing device is configured to operate; In the case where the guide passes through a structure other than the side wall hole of the screening program, Except that no guides are set, For the same structure, The gas flow of the mixed gas when the fine powder removing device constituted by the condition is operated. Further, when the "screening program 3" side wall is extended in the axial direction of the center axis 在内 of the inner tube ίο to overlap with the position of the outflow pipe 70, In the side wall of the screening program 30, The air i passing through the screening program hole 31 on the portion overlapping the outflow pipe 7〇 in the axial direction of the central axis 11 of the inner cylinder 10, The airflow 8 of the air 1 flowing in a spiral shape in the annular space 2 is weakened, The gas stream 6 of the mixed gas 3 which spirally flows along the inner wall of the screening program 30 is also weakened. The efficiency of removing the fine powder 4 is lowered, In the micropowder removing device of this embodiment, As shown in Figure 1, Dijon diagram, Fig. 7(c) shows a non-porous ventilation provided for blocking ventilation in a portion of the side wall of the inner cylinder 10 which is overlapped with the outflow pipe 70 in the axial direction of the inner cylinder 1'. a blocking portion (a side wall of the lower tubular portion 13), Therefore, the airflow 6 of the mixed gas 3 which spirally flows along the inner wall of the procedural type 30 becomes strong, The removal efficiency of the fine powder 4 can be improved. also, When the inlet 71 of the outflow pipe 70 is open along the side wall of the inner cylinder 10 as the outlet 62 of the inflow pipe 60, In the annular space 2 Α 与, the suction flow rate of the air 1 opposite to the direction of rotation of the airflow 8 of the air 1 flowing in a spiral shape is not large, Therefore, the airflow 8 of the air 1 spirally flowing in the annular space 20A becomes weak, Finally, the gas stream 6 of the mixed gas 3 flowing spirally along the inner wall of the screening program 30 is also changed to 21 201215460, The removal efficiency of the fine powder 4 is lowered, However, the fine powder removing device of this embodiment, As shown in Figure 1, Figure 6, Figure 7 (C), The outflow pipe 70 is provided with a pipe side wall 73 that enters the annular space 20A between the side wall of the inner cylinder 10 and the side wall of the outer cylinder 20, Therefore, the airflow 8 of the air 1 which spirally flows in the annular space 20A becomes strong, finally , The gas stream 6 of the mixed gas 3 flowing spirally along the inner wall of the screening program 30 also becomes strong, The efficiency of removing the fine powder 4 can be improved.

A dust collecting device 94 is provided between the outflow pipe 190 and the blower 93. Next, the action of the fine powder removing device of this embodiment will be described. First, the micro powder removing device of the reference example shown in Fig. 24, In addition to the shape of the screening program hole 41 设置 provided on the side wall of the screen 34 201215460 inspection program 400, It has the same structure as the fine powder removing device of the present embodiment. In Fig. 24, the same structures as those of the fine powder removing device of the present embodiment are denoted by the same reference numerals. As shown in Fig. 24, the screening program hole 410 provided on the side wall of the screening program 400 of the micropowder removing device of the reference example is circular. Therefore, the guiding function of the screening program hole 131 of the fine powder removing device of the present embodiment is not provided. Figure 22, The fine powder removing device of the present embodiment shown in Fig. 23 and the fine powder removing device of the reference example shown in Fig. 24, Both are activated once the blower 93 connected to the outflow pipe 190 is activated.

At this time, Since the screening program hole 410 provided on the side wall of the reference screening program 4 is circular, There is no guiding function of the screening program hole 131 provided by the screening program 13 of the present embodiment, Therefore, the flow of the mixed gas 3 flowing along the inner wall of the inner cylinder 14 in the reference example is formed as the free airflow 5A which is not guided (controlled). That is, In the present embodiment, the object guided by the screening program hole 131 is the free air flow 5A of the mixed gas 3, In the present embodiment, the flow of the mixed gas 3 flowing along the inner wall of the inner fin 140 is formed by the screening program hole 131 35 201215460 ”, , : control: ) controls the air flow 6A. The guiding effect on the screening program hole (3) The conversion of the free airflow 5A of the sigma 3 to the control airflow (4) will be described in the next song. , _ — the unit of mixed gas 3, Before stopping the drive blower 93, - side = screening program 130, 4_ turn-side in the screening program 13〇, 4〇〇 Leaving the 8th to seize the inspection program 13〇, The inner wall is spirally flowed. The effect of strong centrifugal force generated by 5A, The particles 2 and the fine powder 4 in the gas 3 are reliably separated from the screening program (10), The inner and outer sides of the side wall. Compared to the screen hole 131, 41 large particles 2 can not be worn (four) check the program hole 13 Bu, Stay in the screening program 130, The _ ' of the side wall of the 400 is compared to the screening hole 131, 41 () small micropowder 4 is separated into the screening program by the screening program hole 13 and 410, 4〇〇 The outside of the side wall. At this time, in the screening program hole m, 410 has a screening program 13〇, 4〇〇 sidewall airflow 7A of air 1 flowing outward to the outside, Therefore, it is easy to separate the particles 2 from the fine powder 4. The knife leaves the screening program 130, The outside of the 400 side wall, That is, the fine powder 4 in the annular space i5〇A, By means of the air flow 8A left in the spiral flow there, Descent while rotating, Arrive at the annular space 15 and enter below. The b 190 ' flows out from the side wall of the lower cylindrical portion 152 of the outer cylinder 150 in the tangential direction. It is also said that the outside tube 150 flows out. The fine powder 4 contained in the air 1 flowing out of the outer cylinder 150 is recovered by the dust collecting device 94. The clean air 1 is discharged from the discharge port of the blower 93 to the atmosphere. Along the screening program 130, 400 inner wall rotates while screening program 130, 400 stranded period, The particles 2 from which the fine powder 4 is removed fall when the blower 93's 36 201215460 is stopped, Opening from below the lower tubular portion (4) as the inner cylinder 14〇: The factory is widely discharged to the molding machine 90. of course, Along the screening program 130, 400 =: Side _-edge lag (four) „, . The through-hole inspection program holes (3), ·=, and plastic-lips are also removed from the fine powder 4 as foreign matter. This = the driving of the blast (10) is started after the micro-powder removal process, and then the micro-powder removal process is performed again. For example, the fine powder removing device of the present embodiment is processed in batches, and the particles 2 in the early position are treated to remove the fine powder from the granules 2. τ Next, the action of the screening program hole 131 of the present embodiment will be described. As shown in Fig. 22, the length of the _ inspection hole 13 设置 provided on the side wall of the _ inspection program (10) is a hole in the direction perpendicular to the central axis 141 of the inner cylinder 14 。. On the other hand, the centrifugal force is on the side of the mixed gas 3 which spirally flows along the inner wall of the screening program 13〇. Therefore, the inspection hole 131 moves the particles 2 in the mixed gas 3 along the upper and lower sides in the longitudinal direction of the screening program hole 131, and freely mixes the mixed gas 3 flowing spirally along the inner wall of the screening program 3〇. The airflow 5A is guided in the longitudinal direction of the screening program hole 131, that is, in the direction perpendicular to the central axis 141 of the inner cylinder 14A. As is apparent from Figs. 22 and 24, the free airflow of the mixed gas 3 in the private type 130 is screened. The 5A is converted to a control airflow 6A whose lead angle is smaller than its smaller. When the offset processing is performed, 'the time during which the particles 2 stay in the inner wall (screening surface) of the screening program 130 is determined according to the driving time (suction time) of the blower 93. Therefore, the fine powder removing device of the present embodiment and the reference powder are removed. In the apparatus, there is no difference in the time of 2012 201245460 m due to the difference in the screening program holes 131, 41. However, the particles 2 are rotated in the screening program 130, 400 to move according to a certain orbit, but up and down, or change the distance from the inner wall of the screening program 13〇, 4〇〇 (due to the upper and lower Next, the particles 2 collide with each other, and the distance from the inner walls of the screening programs 13G and 4〇〇 changes due to the reaction. In this case, the Korean inspection program hole of the present embodiment is a long hole, and the vertical movement of the particles 2 can be suppressed. It is possible to suppress the movement of the particles, that is, to suppress the collision of the particles 2 with each other. Since there is no contact with the trowel, the particles 2 subjected to the centrifugal force are stably rotated in the inner wall of the screening program 13 按. In this way, the screening hole 131 as the long hole can lengthen the time during which the particle 2 is in contact with the "screening surface. Therefore, the efficiency of removing the fine powder can be improved, and the retention time on the screening surface can be prolonged." The expression expression is "when the surface contact with the screening program is extended = another micro-powder removal device of the second embodiment, which is to be treated as a material: the 2 is placed from below the device, and the treated particles 2 are The type of the sputum is removed 'but the granule 2 as the treated object can also be placed from below the device by the discharge port arranged to handle the granule 2 above the device, only the type of the granule 2 removed from the device (continuous In the case of the type of treatment, the residence time of the mixed gas 3 in the screening program (10) is long, and the removal efficiency of the fine powder 4 can be improved. Here, the side wall of the screening program 13 is provided. The screening hole of the upper one is a long hole in the direction of the right angle of the mixed gas 3 flowing in the longitudinal direction of the mixed gas 3 flowing along the internal flow of the screening program 13 Can = The free air flow 5A of the mixed gas 3 in the crucible is converted into a spiral control air flow 6A smaller than the lead angle of the 201215460, so that the residence time of the mixed gas 3 on the screening surface can be compared with the free air flow 5A. The retention time is long, but the screening program hole 13 provided on the side wall of the screening program 130 is a long hole in the direction perpendicular to the central axis 141 of the inner cylinder 140 in the longitudinal direction, so that the mixing in the screening program 130 can be performed. The free air flow 5A of the gas 3 is converted into a spiral control air flow 6 A ' which is smaller than its lead angle to enable the residence time of the mixed gas 3 on the screening surface to be much longer than that of the free air flow 5A. Further, when the center axis 141 of the inner cylinder 14 is in the direction of the vertical line, the side wall of the screening program 130 forms an inverted conical trapezoid that narrows downward in the direction of the vertical line, and the screening is provided on the side wall of the screening program 130. In the program hole 131, the lower side in the long direction is closer to the central axis 141 of the inner cylinder 140 than the upper side, and the probability that the bottom side of the screening program hole 131 is increased increases, and the guiding function of the screening program hole 131 can be effectively performed. Guide. For example, the fine powder removing device is used as a mixing device disposed in the screening program 13', that is, the free airflow 5A of the gas 2 flowing along the inner wall of the screening program 130 is compared with the free airflow. The direction of the direction of the inner cylinder 140 is substantially perpendicular to the central axis 141 of the inner cylinder 140 to a direction perpendicular to the central axis of the inner cylinder 14 at a right angle direction, and the first long hole shown in FIG. The 501 and the second long hole 502, the protrusion shown in the first figure may be replaced by the self-examination program hole 131, and a groove may be used. ^ In addition, the side wall of the screening program 130 is 141 of the inner tube HO. When the axial direction extends to a position overlapping the outflow pipe 19〇, the side wall ▲Y of the screening program 13〇 passes through the screening program hole 131 which overlaps the outflow pipe 19〇 in the axial direction of the central axis 141 of the inner cylinder 140. The air 1 is such that the airflow 8A which is spirally flowing in the annular space i5qa 39 201215460 becomes weak, and the airflow 6A of the mixed gas 3 which is spirally moved along the inner wall of the screening program 13〇 is also weakened. The removal efficiency of the fine powder 4 is lowered 'But the fine powder removing device of this embodiment As shown in FIG. 19, FIG. 22, and FIG. 23(B), in the side wall of the inner cylinder 140, at least the portion overlapping the outflow pipe 19A in the axial direction of the central axis 141 of the inner cylinder 140 is The blocking ventilation is provided with a non-porous ventilation blocking portion (the side wall of the middle tubular portion 142), so that the airflow 6A of the mixed gas 3 flowing spirally along the inner wall of the screening program 13〇 becomes strong, and the removal of the fine powder 4 can be improved. effectiveness. Further, when the inlet 191 of the outflow pipe 190 and the outlet 182 of the inflow pipe 180 are opened along the side wall of the inner cylinder 140, the rotation direction of the airflow 8A of the air 1 spirally flowing in the annular space 丨5 〇A is opposite. The air suction flow rate of the air enthalpy is not so long, so that the air flow 8 of the air 1 which spirally flows in the annular space 150A becomes weaker, and the air flow 6 of the mixed gas 3 which finally flows spirally along the inner wall of the screening program 30 is also weakened. The efficiency of removing the fine powder 4 becomes low, but in the fine powder removing device of the present embodiment, as shown in Fig. 23(B), the outflow pipe 190 has an annular space 15 which enters between the side wall of the inner cylinder 140 and the side wall of the outer cylinder 150. In the tube side wall 193 of the eighth, the air flow 8 A which spirally flows in the annular space 150A becomes strong, and the air flow 6A of the mixed gas 3 which finally flows spirally along the inner wall of the screening program 130 becomes Strong, the efficiency of removing the fine powder 4 can be increased. As described above, the present embodiment can also obtain the same effects as those of the embodiment. Further, in the fine powder removing device of the present embodiment, the center cylinder 1 attached to the fine powder removing device of the second embodiment can be added. Screening program cover no and second inflow pipe (second inflow port) 12〇. 201215460 As described above, in the examples 丨 to 3, the present invention (jth to fourth inventions) has been described using a fine powder removing device for transporting a well-known suction type pipe as a powder or granule. It is not limited thereto, and various modifications can be made without departing from the gist of the invention. For example, it is applicable to a well-known pressure-feed type pipe transportation as a powder or granule, and it can also be applied as a pipe conveying gas using nitrogen gas or carbon dioxide gas as a conveying gas. Further, in the first to third embodiments, the present invention has been described with respect to a device for removing fine powder for pipe-transporting a powder or granule, but the present invention is also applicable as a pipe for conveying a plurality of powder or granules, and simultaneously mixing and removing the same. Micro powder device. Further, in order to form a spiral flow inside and outside the screening program, the direction of connection between the inflow pipe of the mixed gas and the outflow pipe of the air in which the fine powder is mixed does not have to be provided in either one of the side walls of the cylinder in the tangential direction. The position of the inflow pipe of the mixed gas and the outflow pipe of the air in which the fine powder is mixed in the axial direction of the central axis of the inner cylinder may be different from each other. In this case, both are in the axial direction of the central axis of the inner cylinder. It is also possible to not overlap at all, and partial overlap is also possible. Further, in the case of the third embodiment, the inflow pipe of the mixed gas and the outflow pipe of the air in which the fine powder is mixed may be the same in the axial direction of the central axis of the inner cylinder.
