Description

483814 _ Case No. 89106979_ Amendment 5 、 Explanation of invention (1) Field of the invention: The present invention relates to a device for continuous recycling of synthetic plastic materials, preferably polyester of the material, including those useful for containing the material. The first chamber is provided with a movable tool for crushing and / or mixing the material, and the processed material can be transported from the inside to the second chamber through a vacuum tightly closed channel. A vacuum device is also connected to the inside of the container, and a movable tool is also disposed therein for processing the material, wherein the material is sent from the second container by a screw. Background of the invention: Devices of the type previously described are known (Austrian patent AT 3 96,900). In this device, the material is pulverized and mixed in the first chamber, and pressed into the channel to the second chamber by a turning tool. This second chamber is evacuated to protect materials that are quite sensitive to air contact when heated, and to shorten the drying time. The pre-treated synthetic plastic material flowing to the second chamber in this passage is practically sealed, but it cannot completely prevent the air flow from flowing from the first chamber to the second chamber. The completely sealed state of the second chamber can actually be achieved by a closed device provided in the channel, but in this case, the device will not be able to maintain continuous operation. It is an object of the present invention to improve a device of the aforementioned type so that it can operate continuously while maintaining sufficient vacuum tightness to the second chamber. Therefore, the material to be processed can be processed gently, and in particular, the degradation of the molecular chain can be prevented as much as possible. The method of the present invention for achieving this goal lies in a screw that is carried in the channel by a bearing, and the screw thread of the screw can make the material

483814 Case No. 89106979 a. Revision V. Description of the Invention (2) Transferred from the first container to the second container and placed in the material to be transported will cause obstacles to communication between known places. The chamber does not turn because the screw has at least one compression zone for the air which has at least one material that blocks the material being sent. Continuous operation of the device (a screw in the material flow channel treated by the Austrian patent AT has not been evacuated) The rod will only move in this first movement. Therefore, use a sensitive material 'special room', where the element is located in the flow. This resistance area is sufficient to turn. The direction of E 128, 898 is regarded as a rod. However, and the device This device is reached in the chamber, except that polyester is in the threads and the second volume of the channel, and a plug element is provided to achieve a vacuum seal in the plastic material, instead of T). The next chamber is in such a device, and the first unit cannot operate continuously, and it will not be able to effectively process the material in a certain predetermined material condition. Summary of the invention: In the spirit of the present invention, if the screw is an agglomerating (Agg 1 merating) screw, significant benefits will be obtained, because in this way, it can obtain highly sensitive high quality Agglomerated synthetic plastic materials, especially polyesters. Compared with the device used for plasticizing (P 1 asticizi ng) the material, the use of this coalescing device needs to be input to the coalescing screw shell suction hole, which is generally crushed in advance. The energy in the treated synthetic plastic material is only required to slightly combine it into pieces without plasticizing it. Therefore, it can be said that some particles of synthetic plastic material will stick to each other, or that the synthetic plastic material is sintered together, so this material will be sent to the second container in the most likely loose form. indoor.

1_Press 1 483814 Case No. 89106979 Amendment V. Description of the Invention (3) As is known, for coalescing screws, the ratio of the effective screw length to the nominal diameter of the screw is less than 16. In the spirit of the invention, this ratio is a particularly advantageous value between 4.5 and 12. As far as the "effective length" of the coalescing screw is concerned, it can be understood that the distance refers to the area at the downstream end of the screw and the material next to this end is supplied to the suction orifice in the screw housing. the distance between. In addition, on the coalescing screw, the thread in the conveying area (that is, the area located near the material outlet) is cut deeper than the plasticizing screw. In the latter, the ratio of the depth of the thread to the outer diameter of the screw is usually equal to about 0.05 to 0.8, and on coalescing screws, this ratio is generally equal to between about 0.1 to 0.12 . Within the spirit of the present invention, it can be made into a blocking element in several different ways: According to a preferred embodiment of the present invention, the blocking element is composed of a thread, and the direction of its spiral is the same as that of the screw. The threads are reversed. Therefore, this reverse thread will have a transport effect, which is opposite to the screw transport effect and can be offset by the latter. In this way, the treated material can become blocked in the area of this counter-screw. The above-mentioned effect can be achieved in a simple way by the following structure. When measuring along the axial direction of the channel, the screw is longer than the reverse thread, and / or the screw thread is cut to The reverse thread is deep. Another particularly advantageous structure of the blocking element within the spirit of the invention is that the blocking element is constituted by a member having a rib which spans, especially perpendicular to the direction of flow of the material, and Set. This member can act to block the material conveyed by the screw, especially if two or more ribs can be provided. In order to obtain favorable flow conditions, it is suitable to provide at least two ribs, has a smooth appearance, and is arranged to be regarded as one in the direction of material flow.

483814 Case No. 89106979 Amendment V. Description of the Invention (4) The following blockage of the spiritual orientation of the Observation Common Blocking Element with which it abuts against the second edge of its periphery, can be particularly close Matching. This area of the chamber does not constitute the disassembly, but the inaccessible parts of the channel are input by the reverse screw. If it is rotated, the element can be the same as the side of the channel wall plug element or along the side of the chamber. It is suitable to ensure that the inner wall will be damaged by this assembly and the channel is tightly provided with ribs. The grain can be sent in the opposite direction. If the direction is reversed, the resistance can be fixed and can be turned because it is part of the body. It is better to connect the high-voltage part of the structure to the maintenance part of the body in a situation where the threaded wall is in a deviating manner. The structure of this part is rotated by a separate driving device so that The screw is the opposite). However, the screw of the reverse screw actuated in the present invention is correspondingly provided with a plug element which can be connected to the screw for the purpose of omitting the respective driving means. The ribs are immovably provided in the channel, but it is better to move, especially to connect with the screw in such a way that it will not require a way of blocking the material core flowing on its downstream side, which In the side wall containing the resistance chamber, the energy is destroyed as much as possible. Considering the force of the part of the shell to the screw, the end formed by the compact member is pushed out to collect the material. If the channel is relative to the connection, and if it is particularly suitable in the spirit of the invention required, the outline of the push-out portion of the plug element is the second ground driven by the turning tool that is larger than the area where the channel is connected. Smooth. The mixture thus formed is suitable for locating the blocking element within a member ' and the shell member is an acceptable shell. The stresses that occur during this force can reach 300 bar or higher, while the connection is necessary. If blocked, it is suitable for this coalescing screw

Hi

483814 Case No. 89106979 Λ_a. Amendment 5. The periphery of the thread cutting portion and the plug element in the description of the invention are reversed, and their teeth are the same as before. After being in the first god, the continuous operation on the vacuum device makes the basic cover The material type of the screwing tool on the shell is suitable for cutting a predetermined portion of the particles in the bottom of the rod into the second chamber of the rod. The inner wall of the channel is cut from the radial direction. It does not have to be opposite, and it can be placed in a container first when the space is facing the heat. This can be done, for example, by using a centrifugal force at the surface of the suction hole. However, the channel area is around. This goes into the first, and. But, its hope time. Because of this, the porous type of the processing chamber in the moisture can also be used to continuously open the mouth, so that, and here is the second at least to avoid the second chamber makes the cause These will be equivalent to the plug element between the measurement gear and the pass gear, and will be fed by the vacuum gate of the wheel gate. This material is less likely to be the best. In the container of these embodiments, the vertical particles are not yet finished, the particles are dry enough, and the material particles are sucked into the hole, which is deeper than the ribs of the blocking element. It can be seen that the axis of this channel is radially symmetrical and phase-shaped, and most of the materials are treated with recycled materials, especially polyester-sensitive. In order to avoid the adverse effects of this material, the tightly sealed state of the present invention, and the tightly connectable state that can be connected to the pumping can be achieved by the operation of a rough gate switch, which is arranged on the second chamber. The position is applied by the tool, and the axis line rotation at the entrance of the hair is all rotated in the first volume, and the particles that are not sufficiently dry and humid can be set in the first mouth and sent out in this volume. The essence of the material is placed in the upper tool room, and the tool is pushed for a long time, or the interior of the screw containing the two-compartment two-compartment screw is applied to the pressure wiper. The orbit in this chamber is reasonable. The finished material input and output screw stays in the first moisture-retained internal storage-inner higher position

mm Page 10 483814 Case No. 89106979 Amended in May 5. The function of the invention The chamber allows the particles to be held by the time and time in the south of Wendi in order to be the second tool, and it is south. The powder on the person's grain is appropriately located in (6) The spirit of the room will be exhausted after passing through a resident area after the tools in this material flow will enter the volume in the container. Part of the knot tool 1¾. . This can satisfy the possibility that for a long period of time, if in addition to its guideway provided with another coaxial setting tool, the combined orbits can be combined so that the material entering the second chamber will move and cause the material flow caused by the convolution. The granules rise along the side wall of the chamber, so it drives upward movement, and only when it can reach the suction orifice of the conveying screw and vacuum the granules in the second volume as loosely as possible. In the bottom area of the container of the present invention, the tool that rotates, especially the type of the impact element, has the most orbital effect, and the crushing effect applied to the second container is more enhanced than that provided in the bottom area of the container. The entrance of these additional sum channels in the second volume is the same as that of the preferred embodiment of the invention: In the embodiment shown in Figs. 1, 2 and 3, the material to be treated, such as a polyester material However, in some cases, it may also be polyamide and other plastic materials that are sensitive to water vapor, or materials that are sensitive to oxygen. They are sent to the first container 2 through a feed funnel 1, which The chamber is rotationally symmetrical to a staggered axis line, and has a flat horizontal bottom 3 and a vertical side wall 4. In order to be able to process the material in the chamber 2 under vacuum, the suction opening 5 can be tightly closed by a closed gate 55. The evacuating chamber 2 is provided with a evacuating device 6 having a vacuum pump and connected to the chamber 2 via a line 7. The tool 9 mounted on the disc 8 can be wound around the vertical axis of the chamber in the bottom area of the chamber.

483814 _case number 89106979_year month__ V. Description of the invention (7) The line is rotated by the motor 11 and driven by the shaft 10 to rotate. The shaft 10 intersects the bottom 3 of the chamber 2 and is sealed tightly by a seal 12 in a vacuum. An opening 13 is provided in the side wall 4 of the container 2 through which the material processed in the container 2 can be sent to the casing 14 of the screw 15. In this regard, it is the centrifugal force that is applied to the material in the chamber 2 by the rotating tool 9, and in addition, the tools 9 will press the material into the material in a pat-like manner. Openings 1 to 3 inside. The screw 15 can be, but is not limited to, a coalescing screw, that is to say, the conveying area, that is, the inlet area of the housing 14, and the depth of the internal thread 5 2 is greater than that of a general plasticizing screw, and the The ratio between the effective length of the knot screw and its nominal diameter is less than 16; preferably, the ratio is between 4.5 and 12. In the embodiment shown, this ratio is approximately equal to 6.6. As shown in Figure 2, the core diameter of the screw 15 is continuously increased along the conveying direction, at least in part of its axial length, so the depth of the thread 5 2 will gradually decrease in this direction. In order to increase the pressure on the material conveyed by the screw along the conveying direction. This screw is driven by a motor 16 through a gear device 17 to make a rotational movement around its axis. The cover 14 of the screw constitutes a passage 18 through which the material can be transported by the screw 15 from the first chamber 2 into the second chamber 19. The entrance 20 of the passage 18 is arranged on the vertical side wall 21 of the container 19, and constitutes the entrance opening of the pre-pressed material, and is arranged around the second container 19 At the position where the orbit of the vertical axis maneuvering tool 22 is high. These tools are mounted on the disc 23 in a manner similar to that in the first chamber 2 and are driven by the rotary motion of the motor 26 via a shaft 25 intersecting the bottom 2 4 of the chamber 19. The seal 2 7 seals the shaft 25 with respect to the bottom 2 4 in a vacuum tight manner. In order to be able to vacuum in the chamber 19

483814 Amendment No. 89106979 V. Description of the invention (8) This material is also evacuated. In this regard, it is equipped with a vacuum device 2 8 and its vacuum pump is connected via line 2 9 Within the chamber 19. After the processed material is discharged from the second chamber 19, the screw 30 is connected to the side of the chamber in a tangential manner, and the centrifugal force applied to the material by the tool 22 is passed through the orifice 3 2 It is squeezed into the casing 3 1 of the screw from the internal chamber 19. As in the case 2, the pressing action here can be enhanced by the wiping action of the tool 2 2, and in this regard, each of the tools 9, 2 2 can be provided with an operating edge 3 3 (Figure 2), which is angled in the direction opposite to the direction of the rotation (arrow 3 4). The screw 30 is driven by a motor 36 via a gear device 35. The cover 31 is appropriately provided with a resistance heating device 37 on the outside thereof, so that the material carried by the screw 30 can be maintained at a desired temperature. The conveying direction of the screw 30 is indicated by the arrow 38. At the end of the screw 15 close to 20, a blocking element 39 is provided in the channel 18, which can block the material sent by the screw 15 and thus make the pressure on the material Will increase along the axial length of the blocking element 39. This axial length is relatively short compared to the axial length of the screw 15, and in the example shown, it is approximately one-eighth the latter. This increased pressure will act on the material, so that the channel 18 can be reliably vacuum-sealed. Therefore, when the vacuum inside the first chamber 2 must be cancelled for any reason, the first The vacuum in the second chamber 19 is still maintained. In the case of synthetic plastic materials to be treated, such as polyester or polyamide, such as those used to form agglomerated articles, when heated, it is quite sensitive to moisture and oxygen. Good working condition

Page 13 483814 _Case No. 89106979_ Year Month Amendment_ V. Description of the invention (9) The situation is very important. In the embodiment shown in FIGS. 1 to 3, the blocking member 39 is constituted by a thread 40 provided at the exit end of the member constituting the screw 15, so that this thread is integrated with the screw 15 , But the direction of its thread is opposite to that of the screw 15. Therefore, when the screw 15 rotates, the thread 40 conveys the material along the opening 13 toward the casing 14, and therefore in the direction opposite to the conveying direction of the screw 15. The axial length of the screw 15 is much longer than the axial length of the blocking element 39. The axial length of the screw 15 can make the conveying action of the thread 40 offset by the conveying action of the screw 15. However, the former's conveying action will increase. Pressure on the material in the area of the blocking element 39. The material thus further compressed is pushed along the thread 40 towards the entrance 20 of the channel 18, or when these threads have a smaller outer diameter than the thread 5 2 of the screw 15 as shown in FIG. 3 , The material will be pushed over the thread 40, that is, the thread 40 will be crossed by π. Alternatively, if both threads have the same outer diameter, the portion of the inner diameter of the cover 14 in the region of the blocking element 39 can be correspondingly increased, but in terms of manufacturing considerations, The former method is better. It can make the blocking element 39 separate from the screw 15 and rotate it by the driving device of the blocking element itself. For example, it can be driven by an axial rod that intersects the core of the screw 15. The core of the screw is formed as a hollow rod. However, if the blocking member 39 is integrally formed with the screw 15 or is a member separate from the screw 15 but connected to co-rotate with it, the required work can be made much less. The advantage of the latter variant is that it can be replaced individually as a component that needs to withstand extreme stresses, especially during repairs or parts replacement.

Description of the invention (10) In order to facilitate this work, the blocking element 14 in the casing 14 may also be composed of individual components 4 1 (Figure 3) The structure is connected with the rest of the cover 14 in a manner that the parts of 39 can be tight.丄 In terms of oblique unloading but hermetically sealed state, it is also necessary because the pressure required in the channel 丨 8 (up to 300 bar or higher) must be able to withstand and not occur at the height of 4 consecutive lives. In the case of a leak, a tight connection is necessary to connect the premises as shown in FIG. 3, and the d-side ends of the blocking element 39 and the 20 entrances of the channel 18 are pushed. The function of this pushing portion 5 丨 is that the mesh can be gathered in its surrounding area through the material of the blocking element 39, and its shape can be adapted to the shape of the side wall 2 丨 of the chamber 9. Another advantage is that the sintered particles can be kept relatively small, and the rotation around the axis of the chamber driven by these tools will be minimized at the area of the entrance 20. The pots are shown in Figure 4—changes. Here, the blocking element 39 is constituted by a member 42 connected to the screw 15 before. This member has: ribs 43 arranged along the flow direction of the material, and has a smooth shape. This "large diameter is It is better to take it than the cover 14 or the component 41 connected to it. This blocking element 39 can block the flow around its outer periphery :: The second material compresses the material, thereby obtaining a vacuum tight sealing blocking element 3 The pushing part 51 of 9 is Gugu α, j mouth happy fruit. ^ 1 has the same function as the one illustrated in Figure 3. Another variation is that the blocking monument containing the right direction of 0 is used to = A coin is placed across the screw 15 and the soil is not used as the blocking element 39.
