解的是可有其他實施例。因此，本發明之料不應受限於 在以下說明中揭露或在圖式中顯示之結構的細節、元件的 配置。本發明可為其他實施例且可以各種方式實施。又， 在所述較佳實施例中，為了清楚起見，將依靠特定用語。 在此應了解的是各特定用語包括以一類似方式操作以達成 一類似目的之所有技術等效物。只要可能，圖式之類似元 件係以相同符號表示。 201103720 本發明之可定位喷嘴總成協助促進各種聚合材料之結 晶且亦促進這些及其他材料之乾燥，同時消除已在先前設 計中遭遇之一集塊之可能暫停點。利用注射入該顆粒輸送 管路之加壓空氣或其他氣體，該顆粒漿液之速度增加。結 果是，由於速度增加及抽吸輸送液體遠離這些顆粒之表 面，該等顆粒受該輸送液體支配之時間減少。由於速度增 加，該等顆粒在該輸送液體中之停留時間較少，容許該等 顆粒保持比它們受該輸送液體支配一較長時間更多的内 熱。事實上，增加保持之内熱有助於該等顆粒之結晶。這 效果藉抽吸該輸送液體遠離該等顆粒之表面而更加強，使 得對該輸送液體之熱損失減少。 為了達到該等顆粒之最大通過量，本發明容許該喷嘴 之外形尺寸及位置可以調整。這對於漿液由該造粒機輸送 至該乾燥機之速度是重要的，這會再衝擊該系統藉抽吸分 離該等顆粒與該輸送液體及增加被該等顆粒保持之内熱之 量的效率。改變該喷嘴之外形尺寸及位置亦可用來改變該 漿液通過輸送管路之流動模式，產生或多或少之渴流，以 達成與被加工之材料相關之特定需求。 以下請參閱第2圖，大致以符號100表示之本發明之可 定位喷嘴組裝成大致以符號15表示之輸送管路，該輸送管 路15連接造粒裝置10與乾燥裝置20及任何後續之後處理。 一熔化及混合裝置（圖未示）連接於造粒機10，該造粒機10 連接於注入管12。輸送液體透過注入管12導入造粒機10之

軸環122引導該後端。該噴嘴管11〇及軸環122可以是一單體 • 構造，但最好該喷嘴管110及轴環122是例如藉焊接連接在 一起之分開元件。該噴嘴管110及軸環122最好焊接在該軸 環之各端，在焊接件124與焊接件126處。 δ玄噴嘴管11〇及轴環122可變地定位且可自由地滑動通 過該殼體128 ’該殼體128之前端130螺接於一密封過渡轴環 132 ’該密封過渡軸環132在接合部112連接於肘管1〇2。該 喷嘴管110之前端被滑動地支持在該軸環132之中央孔133 内’在該殼體128内且於環繞該喷嘴管11〇沿圓周定位的是 一拉伸彈簧134。至少一導銷136連接於該軸環122，該導銷 136對齊且可定位在殼體128中之至少一溝槽138内，如第5 圖所詳示。對較大輸送管路及喷嘴總成而言，具有分別可 定位地對齊在殼體128中之兩溝槽138以提供較大之調整能 力的至少兩導銷136是較佳的。溝槽138係沿著殼體128之長 度呈直線長形且形成如第3圖所示之至少一角凹部14〇，或 15 201103720 如弟5圖所示之多數凹部“ο、mi。 請再參閱第3圖’最好是一螺旋彈f之拉伸彈菁134放 置在轴環122之前面上且在密封過渡軸環132之後面上。在 第3圖中，該拉伸彈簧134於該喷嘴管總成之抽出位置時拉 長。第4圖顯示該拉伸彈簧134在該可定位喷嘴總成ι〇〇之最 前方位置中被壓縮’其中該喷嘴管UQ完全被插入該肘管 102之内腔中。如圖所示，當完全被插入時，該軸 收納在該殼體128中’且導銷136被鎖定在角凹部14〇中，如 第更清楚地顯示。另-方面，當該噴嘴管僅部份地被插 入時’該導銷136將被鎖定在角凹部141中。 噴嘴管11〇最好被密封地定位在密封過渡軸環132中， 請參見第3與4圖。密封係藉包括〇環、“四邊形，，環、機械密 ^等發明所屬技術領域中具有通常知識者已知之任何機械 裝置，且不限於此。較佳地，密封係使用被扣持在密封過 渡輛環132之一圓周溝槽M4中的至少一 〇環142。◦環142密 封地嵌套環繞噴嘴管110之直徑，使得喷嘴管11〇可以被密 封地且可滑動地定位通過該至少一0環142。較佳地，至少 兩0環142分別被密封地定位在兩圓周溝槽144中。最佳地， 多數〇環14 2被密封地定位在同樣多數之圓周溝槽丨4 4中。 第5圖顯示可定位喷嘴總成100之一部份，其中如同等 如上地在第2a圖中顯示與說明者，該噴嘴管11〇被完全插入 肘官102之内腔中’大致與接合部114齊平。軸環丨22已被插 入殼體128中且導銷136已移動通過溝槽138而可被牢固地 定位在角凹部140中。 16 201103720 喷嘴管110可以被大致定位在由密封過渡軸環丨32内腔 内之肘管102的外部外側到至少該接合部114或者超出該接 合部114的整個範圍内。較佳地，該完全抽出位置係大致與 肘管102之外部齊平且該完全插入位置係大致在該接合部 114 處。 該喷嘴管11 〇在該可定位喷嘴總成1 〇〇内之移動可以藉 包括手動或最好利用一或多個自動控制系統等任何適當方

具有一用以定位該喷嘴之自動控制系統之本發明之可 疋位喷嘴的一較佳實施例顯示在第6a_6d圖中，在這實施例 中，該喷嘴使用一被使用者控制之氣壓缸氣動地移動至所 需位置。該氣壓缸最好是-大致以符號154表示之磁輕合無 桿壓缸，其磁性地結合-載架16G，該載架⑽藉一托架或 銷162固定連接於該喷嘴管11〇及軸環122。如圖所示，在第 6a與6c圖中，銷162最好連接在該載架16〇與軸環122之間，

可使用在本發明之一磁耦合無桿壓缸係在Series CY1B下由美國之SmC公司製造。如第7圖所示，該無桿壓 缸154包括一其中具有一活塞172之缸管170，該活塞172設 有一第一磁鐵174。一第二磁鐵175被支持在該載架160之— 本體176中且在該缸管170外側。 一用以使用該氣壓缸移動該喷嘴管110之控制電路係 顯示於第8圖中且大致以符號190表示。相對於喷嘴末端 155，該氣壓缸154在其遠端157處具有一第一空氣入口 156 且在其近端159處具有一第二空氣入口 158。為了移動該喷 嘴管110至第6c與6d圖所示之完全插入向前位置，致動—如 按鈕180之内推機構，這將改變空氣操作之阻擋閥181之位 置’以將加壓空氣注射入該第一空氣入口 156。該空氣在兮 近知)159之第二空氣入口 158處亦被注射入一單向閱184，vsr

寸差所造成之結果，較佳之角度範圍是由大約30°至60°，且 更佳之角度是大約45°。進入該乾燥機入口 22之加大肘管24 有助於被高速抽吸之顆粒/水漿液由該輸送管路18轉移至 該乾燥機20之入口 22中且減少顆粒集塊於該乾燥機20中之 可能性。 喷嘴管110之外側表面及流入管118、肘管102、流出管 116與輸送管路18之内腔可藉表面處理來塗覆以減少研 23 201103720

[Technical Field of the Invention; J Background of the Invention 1. FIELD OF THE INVENTION The present invention relates generally to underwater pelletizing systems, and in particular to a gas injection nozzle for use with such systems. I: Prior Art 3 2. Description of the Related Art Those having ordinary skill in the art have discovered that it is advantageous and sometimes necessary to produce partially or fully crystallized particles. In order to assist in the realization of the crystallization, in U.S. Patent No. 7,157,032, U.S. Patent Application Serial No. 2,05/0110,182, and U.S. Patent Application Publication No. WO2005/051623, and WO2006/127698, The assignee of the present invention has disclosed the use of a nozzle' and pressurized air or other gas can be injected into the slurry slurry through the nozzle to assist in reducing the transport of liquid between the upstream granulation process and between the swim and subsequent processes. </ RTI> </ RTI> </ RTI> </ RTI> </ RTI> </ RTI> </ RTI> </ RTI> </ RTI> </ RTI> </ RTI> </ RTI> <RTIgt; Similarly, WO2007/027877 discloses the use of a mouthpiece through which pressurized air or other gas can be injected into the slurry of particles to promote the suction of liquid by the particles in the slurry of particles. By reducing the residence time of the particles in the transport liquid between the upstream granulation process and the downstream and subsequent processes, the moisture content of the particles is reduced by 201103720. The reduced residence time will also result in more (4) retention within the formed particles, and thus reduce the amount of water available for inhalation of the particles. This towel (4) is also owned by the (4) person of this issue and is also hereby incorporated by reference. At some two conditions, the τ granules will condense or form agglomerates during the granulation process. There are many possible formations of particle agglomerates, in which the viscous particles are general and the cores are formed when they are formed, and they have a tendency to be captured at the so-called "hang up p〇lnts" + The phrase "pause 1 will be suspended and stagnant in the block of i-making granules or particles. · Workmanship—blocks the location of the deposit. For example, the collection of particles sneaky in the w-delay formation of 'excessive smelting material flowing through the die hole on the template thus producing - unwanted large particles. Large particles are not the only problem. Particles with a size of (five) also produce problems. Adhesive I1 particles that are in contact with the nozzle or particles that are still soft will be "crushed, and stick to the nozzle due to their viscosity and the speed at which they move. Finally, more and more particles stick to the nozzle. The particles on the particles contact and the particles begin to stick to each other, producing a particle block 'also known as a block. Finally, the particle block becomes large enough to transport the liquid and the particles flow through the (four) delivery tube, which will force the granulation. The process is stopped. - Such a pause point has been found in the granulation line using the apparatus and method for inserting pressurized gas as described in the aforementioned patent and application, that is, the point where the body insert A nozzle is located in the granule conveying pipe According to these previous & examples, the nozzle for injecting the air is as shown in Figure i and is roughly robbed by the bowl 2 . The fixed nozzle tube 210 of the first feather/technical technique is preferably connected to the elbow 202 by welding at the 201103720 joint 214. The fixed nozzle assembly 200 cannot be removed for activation. Since it is not steerably positioned to allow the particle slurry to flow freely around the periphery of the fixed nozzle tube 210, it may be a source of blockage due to particle agglomeration. Similarly, the cold-holding position limits the degree to which the injected air or other gas can be adjusted through the valve. Accordingly, there is a need for a positionable nozzle that can be adjusted to optimize crystallization and/or drying of the particles produced by the underwater pelletizing system. SUMMARY OF THE INVENTION In view of the foregoing, it is an object of the present invention to provide a positionable nozzle through which pressurized gas is introduced into a conveying device of an underwater granulator to increase one by one granulation.

Another object of the present invention is to provide a positionable nozzle that is concentrically centered about the centerline of the downstream device. It is a further object of the present invention to provide a positionable nozzle through which pressurized gas is introduced, which increases the velocity of a slurry of particles that is delivered to and through a drying device by a granulation device such that the particles The heat therein is maintained to promote drying of the particles such that the moisture content of the particles leaving the drying apparatus is less than about 1. 0% by weight, and less than 0. 5 wt% is more preferred, and is less than 0. 25 wt% is the best. It is a further object of the present invention to provide a positionable nozzle through which pressurized gas is introduced to increase the velocity of a slurry of particles transported by a granulation device through a drying device such that the particles Internal heat is maintained to simultaneously promote both drying and crystallization of the particles. Another object of the present invention is to provide a positionable nozzle through which the pressurized gas is introduced in accordance with the foregoing objects, which increases the speed of a slurry of particles which is delivered to and through a drying device by a granulation device.

DETAILED DESCRIPTION OF THE INVENTION While the preferred embodiment of the invention has been described in detail, it is understood that other embodiments are possible. Therefore, the material of the present invention should not be limited by the details of the structure disclosed in the following description or the structure shown in the drawings. The invention is capable of other embodiments and of various embodiments. Again, in the preferred embodiment, specific terms will be relied upon for clarity. It should be understood that the specific terms include all technical equivalents that operate in a similar manner to achieve a similar purpose. Whenever possible, similar elements of the drawings are denoted by the same symbols. 201103720 The positionable nozzle assembly of the present invention assists in promoting crystallization of various polymeric materials and also facilitates drying of these and other materials while eliminating possible pauses in one of the blocks that have been encountered in previous designs. The speed of the particle slurry is increased by pressurized air or other gas injected into the particle delivery line. As a result, as the speed increases and the suction delivery liquid is away from the surface of the particles, the time at which the particles are dominated by the delivery liquid is reduced. Due to the increased speed, the particles have a lower residence time in the delivery liquid, allowing the particles to retain more internal heat for a longer period of time than they are subjected to the delivery liquid. In fact, increasing the heat within the retention contributes to the crystallization of the particles. This effect is enhanced by drawing the transport liquid away from the surface of the particles such that the heat loss to the transport liquid is reduced. In order to achieve the maximum throughput of the particles, the present invention allows the size and position of the nozzle to be adjusted. This is important for the speed at which the slurry is conveyed by the granulator to the dryer, which in turn impacts the system by pumping the efficiency of separating the particles from the transport liquid and increasing the amount of heat retained by the particles. Changing the shape and location of the nozzle can also be used to alter the flow pattern of the slurry through the transfer line, creating a more or less thirsty flow to achieve the specific needs associated with the material being processed. Referring now to Figure 2, the positionable nozzle of the present invention, generally indicated at 100, is assembled into a delivery line generally designated by the numeral 15, which is coupled to the granulation unit 10 and the drying unit 20 and any subsequent processing. . A melting and mixing device (not shown) is coupled to the granulator 10, which is coupled to the injection tube 12. The transport liquid is introduced into the cutting chamber of the granulator 10 through the injection tube 12, and it is mixed with the particles in the cutting chamber to form the slurry 10 201103720. The particle slurry is discharged into and through the sight glass 16 via the discharge tube 14 and then passed through the nozzle assembly 100 in the delivery line 15. A particulate accelerating material is injected and directed into the delivery line through the positionable nozzle assembly 100 to reduce the time during which the particles are dominated by the delivery liquid. Due to its inert nature and immediate availability, the particulate accelerating material is preferably air. However, other gases having inert properties such as nitrogen or the like may also be used. The accelerated particles and transport liquid enter through the transfer line 18 and pass through the dryer assembly 20, which is dewatered and dried in the dryer assembly 20. The details of the accelerated particles and the transported liquid are explained below. The melting and mixing device (not shown) may be any conventional device or combination thereof and may include, but is not limited to, a melting vessel, a single screw extruder, a twin screw extruder, a static mixer, a continuous mixer. , Closed mixer, etc. The granulator 10 may be a water ring granulator, an underwater granulator, etc., and is preferably an underwater granulator in which one of the ordinary knowledge is known in the art to which an extrusion die is embedded. . The transport liquid can be any liquid and preferably water, in addition to water, which can be used to granulate other liquids, including ethanol, water-ethanol mixtures, mineral oils, vegetable oils, glycol mixtures, and the like, in accordance with the present invention. Alternatively, water or other transport liquids may contain a plurality of additives including, but not limited to, flow agents, coatings, defoamers, cosolvents, and the like. As used herein, when referring to "liquid" or "water" in connection with the transport liquid, these references refer to any liquid suitable for use as a transport liquid, with or without additives, and not only water. The granulated and transported material of the present invention may be a polymer, a wax, and other extrudable materials which are granulated at 201103720. For example, such materials may include polyalkylenes, polyethers, polysulfoniums, polyamines, polyamidomines, polyfluorenes, polycarbonates, polyurethanes, fluoropolymers, ethylene.

It includes pneumatic, electrical, electronic, hydraulic devices and methods, and optionally includes programmable logic control, PLC. Manual and automatic control capabilities can also be combined in the same nozzle assembly. Since it is determined by the position of the corner recess 140, the manual control must specifically arrange the positioning. However, if the move is automatic, there are a number of locations available. For example, the guide pins 136 and associated grooves 138 and corner recesses 14G and 141 used in Figure 5 will not be expected to be controlled using an automatic control system. A preferred embodiment of the collapsible nozzle of the present invention having an automatic control system for positioning the nozzle is shown in Figures 6a-6d. In this embodiment, the nozzle uses a user controlled pneumatic cylinder pneumatic Move to the desired location. Preferably, the pneumatic cylinder is a magnetically coupled rodless cylinder, generally indicated at 154, magnetically coupled to the carrier 16G, the carrier (10) being fixedly coupled to the nozzle tube 11 by a bracket or pin 162. Collar 122. As shown, in Figures 6a and 6c, the pin 162 is preferably coupled between the carrier 16 and the collar 122 and re-welded to the nozzle f 11Q. However, the shutoff 162 can be directly connected to the nozzle tube 110. The pin 162 can be coupled to the carrier 160 and the collar 122/nozzle tube 110 by any suitable connection method known to those skilled in the art, but is preferably bolted to the carrier 160 and the shaft. Ring 122. The pin 162 is passed through a slot 139 in the housing 129 through a housing 129 that surrounds the nozzle tube 110 and the collar 122, as shown in Figures 6b and 6d. A magnetically coupled rodless cylinder system that can be used in the present invention is manufactured by SmC Corporation of the United States under Series CY1B. As shown in Fig. 7, the rodless cylinder 154 includes a cylinder tube 170 having a piston 172 therein, and the piston 172 is provided with a first magnet 174. A second magnet 175 is supported in the body 176 of the carrier 160 and outside of the cylinder tube 170. A control circuit for moving the nozzle tube 110 using the pneumatic cylinder is shown in Fig. 8 and is generally indicated by reference numeral 190. The pneumatic cylinder 154 has a first air inlet 156 at its distal end 157 and a second air inlet 158 at its proximal end 159 relative to the nozzle tip 155. In order to move the nozzle tube 110 to the fully inserted forward position shown in Figures 6c and 6d, actuation - such as the push mechanism of the button 180, which will change the position of the air operated blocking valve 181 'to inject pressurized air Into the first air inlet 156. The air is also injected into a one-way read 184 at a second air inlet 158 of the air 159. The vsr opens the one-way check valve 184 and releases the air that has been applied to the proximal or front end of the pressure cylinder 154. Thereby, the piston 172 and the carrier 16 磁性 magnetically coupled thereto can be moved forward, and the pin 162 is moved in the slot 139 to the position shown in Fig. 6d. Conversely, in order to move the nozzle tube 110 from the insertion position to the pomelo-out position shown in Figures 6 and 6b, actuating the push-out mechanism as the button 182 changes the position of the air-operated blocking valve 181. To introduce pressurized air main radiation 18 201103720 into the second air inlet 158. The air is also injected into a one-way valve 185 at the first air inlet 156 of the distal end 157, which opens the one-way valve 丨 84 and releases pressurized air that has been in the distal or rear end of the pressure cylinder 154, thereby The piston 172 and the carrier 160 magnetically coupled thereto are moved forward, and the pin 162 is moved in the slot 139 to the position shown in the figure. Between the positioning conditions, the one-way valve 184 and the one-way valve 185 at the pneumatic cylinder 154 are controlled by the control circuit 190, and the air is not allowed to be released by the air inlet 156 or the air inlet 158. The holding position" check valves 184 and 185 also provide speed control to adjust how fast the nozzle tube can be moved. The pressurized air used to move the piston and carrier 160 may be supplied by various air sources, such as air tank compressors known to those of ordinary skill in the art. In the pneumatic embodiment, any number of t-positions between the fully inserted (the && 6d) and fully extracted (the second and the same) positions can be used to (4) injected air The amount of pressurized air in the inlets 156, 158 is achieved. Or, similar to the movement and control of the nozzle tube can be through the use of - linear pressure red, - hydraulic cylinder and power unit, or with - ball screw or Aikem screw (a_% erb one of the feeding motor or stepping The motor, rather than through the magnetically coupled rodless cylinder 154 as is known in the art to which the invention pertains. However, the magnetically coupled rodless cylinder is preferred for the present invention. If desired, a preferred automatic control system for moving the nozzle can be combined with manual movement of the nozzle tube. Preferably, when the granulator is "started", the nozzle tube 11 can be Placed in a withdrawal position 'to avoid its presence becomes a barrier in the delivery line 15 19 201103720. Since it is advantageous to cause the nozzle tube 110 to be withdrawn, the unwanted mass can be at the beginning of the granulation process. The particle slurry is easily formed and allowed to use the full inner diameter of the delivery line U. The positionable nozzle assembly 100 is designed to allow an operator to inject pressurized air or other gas into the delivery line 18 while having a relative The delivery line 18 and the elbow 1〇2 adjust the position of the nozzle tube 11. The nozzle tube 11〇 can be withdrawn and inserted and still produces the desired suction depending on, but not limited to: flow rate, particle pair delivery The liquid ratio, the temperature of the transport liquid, the diameter of the elbow 1 〇 2 relative to the transport line 18, the distance between the elbow 1 〇 2 and the dryer 2 ' and the type of material being granulated are determined. It should be understood that, as shown in Figures 2a, 3 and 4, the outer diameter of the nozzle tube will be less than, for example, the inner diameter of the elbow 1 〇 2 at the joint portion 114. In this regard, the space in the inner chamber It should be large enough to permit the use of the combined maximum size of at least two particles having particles of the largest size for the particular granulation system, through the elbow 102 at the outside of the nozzle tube 11 and at the joint ι4 Between the insides. In other words, between the outer diameter of the nozzle tube and the inner diameter of the inner lumen of the inner tube, the area A is sufficient to at least two particles each having the largest size of the granulator, and can pass through the side by side. And will not block or block in the gap area. For example In other words, the embodiment of the present invention is to the elbow-G. The 75-inch nominal nozzle tube 11〇 and a 2 inch time nominal spray money eight tube 1_ combination, -2 inch private elbow; I; 1G2, and one from the elbow officer 102 to the dryer 2〇1. 5 inches of delivery line 18. Another embodiment is a 0. 75-hour nominal nozzle tube 11Q and -3 · ο 公 公 公 肘 肘 肘 肘 肘 肘 且 且 且 且 且 且 且 且 且 且 且 且 且 且 且 且 且 且 且 且 且 公 公 公 公 〇 20 201103720 The combination of the English and the elbows. The orientation of the nozzle tube 110 relative to the joint 114 of the elbow 102 in Figure 2a may be concentrically centered about the centerline of the joint 114 or above the center, below the centerline to the right of the centerline Or left, or circumferentially surrounding the centerline at any angle, such that the angle between the centerline of the nozzle tube 110 and the centerline of the elbow 1〇2 can be made of 〇. To a maximum deflection angle. The maximum deflection angle is defined as the deflection angle of the outer portion of the nozzle tube 110 that contacts the joint 114 of the elbow 102 and/or the position of the positionable nozzle assembly 1 that extends into the downstream of the joint 114 of the elbow 102. Preferably, the nozzle tube 110 is concentrically positioned and collinear about the centerline of the joint portion 4 of the elbow 102. It should be understood here that the centerline of the joint 114 of the elbow 1 〇 2 is collinear with the centerline of the transfer line 18 downstream of the joint 114. Prior to nozzle tube 110, orifice 146 may be of any shape including circular, square, rectangular 'elliptical, polygonal, etc. and preferably circular. The diameter of the front aperture 146 may be greater than, less than, or equal to the diameter of the nozzle tube 11 and preferably equal to. When the diameter of the current orifice 146 is not equal to the diameter of the nozzle tube no, only the diameter of the portion of the nozzle tube 11 that is not in contact with the nearest annulus 142 is gradually increased or decreased, respectively; see Figures 3 and 4. However, the diameter of the distal aperture 146 cannot be greater than the inner diameter of the sealed transition collar 132. - the final taper 150 of the spray I s 11 显示 is shown in Fig. 9e, and similarly, the front aperture 146 may be a semicircle as shown in Fig. 9e or as in the _ Spiral to C shape. The nozzle officer 110 may be provided with a number of variations including, but not limited to, a conformal shape, at least a sigmoid inner surface, and many combinations thereof. Figure 9f shows a conical tapered nozzle tube 110 in which the taper is reduced toward the front aperture 146. The inside of the nozzle tube 110 may also or alternatively contain one or more fins 152 as shown in Figures 9a and 9b. The fins may be straight or inclined at 90[deg.] with respect to the circumferential edge of the nozzle tube 110, as shown in Figure 9a, or inclined at a smaller angle. Similarly, the fins may be curved or conformed to the circumference of the nozzle tube 110 as shown in Figure 9b. The fins may have a length ranging from less than to the length of the nozzle tube 110, and their height cannot exceed the radius of the nozzle tube 110. Preferably, the fins 152 are smaller than the length of the nozzle tube 110 and the height is smaller than the radius of the nozzle tube 110. When a plurality of fins are included, they can also be placed at any angle to each other and the configurations can be the same or different. The purpose of the fins is to assist in creating more eddy currents within the delivery line 18. In detail, the flow of the pumped slurry of particles can be varied from laminar to eddy. Without wishing to be bound by any theory, the injection of air or other gas into the slurry of particles will draw the transported liquid from the particles such that the transported liquid is transported along the transfer line 18 in a laminar flow while the vapor mist and particles are A more vortex flow propagates through the center of the transfer line 18 along the length of the transfer line 18. In some instances, a more thirsty flow may be required, in which case most of the fins may be advantageously added. In accordance with the present invention, pressurized air or other gas may flow continuously or intermittently through the nozzle tube 110, preferably continuously through the nozzle tube 110. As previously mentioned, this pressurized gas can be used to deliver the particles at a high velocity. This high velocity gas stream can be achieved using a pressurized gas using a standard valve 104 for adjusting the pressure through the transfer line 18 to at least 8 bar, resulting in at least 1 〇〇 cubic meter per 22 201103720 hours. Exemplary traffic. The line 18 is a standard tube diameter, preferably 1. 5 inches in diameter. For those of ordinary skill in the art to which the invention pertains, the flow rate and diameter will depend on the amount of treatment, the composition of the material comprising the filler, the temperature of the liquid to be delivered, the desired degree of crystallinity, the desired moisture content, and the particles and particulates. The size changes. The high velocity gas is in effective contact with the particulate water slurry, the water vapor is produced by suction, and the particles are dispersed throughout the slurry line to deliver the particles to the dryer 20 at high speed, preferably by the pelletizer 10. The transfer to the outlet of the dryer 20 is less than 1 second. The high velocity pump produces a mixture of 98-99% of the particles in a volume of the gaseous mixture in an air/gas mixture. By adjusting the insertion depth of the nozzle tube and adding surface variability within the nozzle, the flow characteristics of the slurry in the delivery line can be varied. Referring now to Figure 2, the angle formed between the vertical axis of the inflow tube 118 and the longitudinal axis of the delivery line 18 can be varied by the height of the granulator 10 relative to the inlet 22 to the dryer 20. It needs to be changed from 0° to equal to or greater than 90°, as shown in Figure 2. This height difference can be attributed to the physical positioning of the dryer 20 relative to the granulator 10 or can be the result of a difference in size between the dryer and the granulator, preferably from about 30 to about 60. °, and a better angle is about 45°. The enlarged elbow 24 entering the dryer inlet 22 facilitates the transfer of the high velocity suctioned particulate/water slurry from the delivery line 18 into the inlet 22 of the dryer 20 and reduces the particulate buildup in the dryer 20 The possibility in the middle. The outer surface of the nozzle tube 110 and the inner tube of the inflow tube 118, the elbow 102, the outflow tube 116 and the delivery line 18 can be coated by surface treatment to reduce grinding, abrasion, corrosion, abrasion and unnecessary adhesion. narrow. The surface treatment may be at least one of nitriding, carbonitriding, and sintering. Similarly, the foregoing surfaces may be subjected to high speed air and fuel modified heat treatment, electrolytic plating, electroless plating, flame spraying, thermal spraying, plasma treatment, electroless nickel dispersion treatment, and electrolytic plasma temperature, either singly or in combination. These treatments metallize the surface, preferably, the metal nitride is fixedly attached to the surface, and more preferably, the metal carbide and the metal carbonitride are fixedly attached to the surface, and more preferably, it will Diamond carbon is fixedly attached to the surface, and more preferably, diamond-like carbon in a wear resistant metal matrix is attached to the surface, and optimally, diamond-like carbon in a metal carbide matrix is attached to the surface surface. Other ceramic materials may also be used and are hereby incorporated by reference. In the case where the diameter of the portion to be coated that must pass through the seal is not properly modified, the thickness of the coating should not exceed about 0. 002 miles. Although the present invention has been described in its preferred embodiments, the spirit and scope of the equivalents of the present invention disclosed herein without departing from the scope of the invention In this case, many modifications, additions, and deletions can be made therein.
