From the perspective of environmental protection, t, there is a real need to change from the economic model of mass production / mass scrap to the economic model of recycling. In this trend, the complete recycling of resin products is urgently needed; for example, 'home appliances The regeneration has been stipulated by law. For the regeneration of materials recovered from resin moldings and re-used as resinous materials, this can only be achieved if the type of resin used is already known to some extent, because There is a special problem, that is, if different types of resins are mixed together, the original functionality of the resin will be greatly damaged. Therefore, there is a need for a resin regeneration system that can be used in The various resin molded articles in the scrapped equipment or devices are correctly classified, and the invention description (2) is regenerated into a brand-new resinous material office equipment or communication device. It can be used in household appliances, office equipment In order to achieve high-quality regeneration, it needs to be correctly identified and classified. A variety of resin molded products including non-flammable additives are identified as materials for resin molded products. Recently, a number of high-performance resin identification devices have been developed. , And is being widely used. However, this-the device must be very careful in its operation, and its maintenance and inspection This series is quite high from the point of view of material identification only. The most effective resin mold material identification method is to provide this resin identification device in each dismantling plant .: From the perspective of economic benefits or the stability of the system From the viewpoint of operation, this method is quite troublesome. In order to operate the above-mentioned resin identification device under a stable control state, and = need to provide-recycle the dismantling waste of the resin molding, and the factory's: Different from the position of the resin identification device.

516996 A7 B7 V. Description of the invention (Class 4) However, the problem is that it takes a long time to perform identification work, so it is not suitable for high-speed processing. On the other hand, the recycled resin products may have coatings and stickers. There are various pollutants with labels or T, and these substances can easily enter the resin during the processing of the resin products, thereby causing considerable deterioration in the characteristics of the resin to be recycled. Although many attempts have been made Removal of foreign matter that is present on the surface of resin products, for example, by mechanical methods and separation or removal by solvents, however, there are still problems in these examples. For example, if the film or label When a crusher such as a ball mill is used for cleaning, the heat generated by friction during the crushing operation will soften the resin, which will interfere with the removal of the resin. Foreign matter adheres to the surface of the product again. In addition, there is another method to dissolve foreign matter by using a solvent to separate it from the resin. However, this method has serious problems, in which the solvent used must be regenerated or discarded, and another problem is that the agriculture for this purpose is quite complicated in structure, so from the perspective of economic benefits In terms of this, this method is not appropriate._ There is also another method of removing the film or label, which is called dry type. Spraying / scratching uses abrasive materials such as sand or metal particles to apply The foreign matter is scraped off from the surface of the resin product. However, the particles of the abrasive material according to this method may adhere to the surface of the resin product, making it a new foreign substance. Furthermore, The resin will also be softened due to the frictional heat of the abrasive material, which will cause the removed rule Lai Cai X 297 public love) 7 2 --- 516996 5 invention description (5 foreign substances will adhere to the product again On the surface, the summary of the invention is to solve the problem, to provide a resin recycling system, and ...: ^ ^ ^ ^ This is the resin waste products crushed in waste equipment crushed into Lipid fragments, and to reduce its apparent =: = aliphatic knowledge "(iv) The resins genus strains, but can be carefully avoided =

In the above description, used "etc." The word "diameter" means the diameter of a circle that has the same projected area as the object. ^ Here: The equivalent diameter of the resin chip is preferably in the range of 3 to 40 millimeters. It is better. The ratio of equivalent straight = resin fragments in these ranges is preferably 80% or more, and more than 90% if the equivalent rhyme of the resin fragments is less than m 丨 during the cleaning operation by the cleaning device The foreign object f may not be removed because the resin fragments are in a powder form. For example, when a cleaning operation is performed by grinding, the grinding cannot be performed. Furthermore, smaller resin fragments may be caused by static electricity. It is easier to adhere to the inside of the crusher or the bag with force. On the contrary, the equivalent diameter of the resin fragments of the right child exceeds 50 mm, and the resin fragments will still maintain the shape of the three-dimensional space, which hinders the volume. The reduced paper size is suitable for SS Home Standard (CNS) A4 specifications (21Q × 297 public directors) 9 ------ 5. Description of the invention (7 minus. ^ Pressing alder can be done in a single step. However, if the size of the resin molding is too large to be introduced into Jintong's crusher, the crushing operation can be performed in two steps, where the resin molded product is first passed through a coarse crusher. It is crushed roughly and then introduced into an ordinary crusher. Since a resin molded product is composed of a single kind of resin, the resin molded products can be effectively reduced by crushing the resin molded products one by one and immediately putting them into a bag body. To avoid mixing small resin fragments with other types of resin, and crush and disassemble the resin moldings of the waste equipment recovered in the factory manually, one by one, and pack the resin fragments Into a bag body, the conveying efficiency can be effectively improved. Since the resin fragments are made of the same kind of resin in the bag body, it is possible to achieve economic benefits by sorting the bag body. ′ For Wan; In order to further enhance the work efficiency, when the resin molded product is made up of the same kind of resin clearly in advance, it can be crushed together and packed in a bag. For example, if a plurality of molded parts of the same shape and function (such as different size feeding trays of a photocopier), and it is determined that they are made of the same resin, they can be crushed together and Packed in-bag body. When there are several resin members of the same shape and the same kind in an obsolete equipment, this method is quite helpful for promoting work efficiency. > The bag system must have transparent parts to avoid exposure to crushed resin particles

Description of the invention (9) Compliant 'and includes the step of recovering the bag body at the predetermined classified classification position on the conveying path. It is predicted that the predetermined classification position is based on the type of resin. The difference is that the sorting and recycling is carried out on the conveying path: the bag body of the packaging resin eight is placed on the conveying path, and the bag of the packaging resin B is recovered by the conveying path ^: grease B / knife red on the conveying path. ... The predetermined position does not need to be specified according to the type of resin. In this example, the sorted recovery is carried out by the bagged resin A) of the resin A that reaches the sorted position, and is guided to a resin A by the conveying path. The centralized container or component is also used to 'guide the bag of resin B that reaches the sorting position to a centralized container or similar component of resin 3 from the conveyance path. The predetermined time of arrival is calculated from the recognition time, the distance between the recognition position and the classification position, and a conveying speed. Although the scheduled arrival = interval can be calculated one by one based on these data, it can also be a predetermined time after the identification time, because the above-mentioned distance and transportation speed are constant. The cleaning device is used to remove foreign substances such as a plating layer, a coating, a label, or a contaminant adhered to the resin fragments from the surface. The cleaning device may include a cleaning container and a stirring member in the cleaning container, and an abrasive surface (rough surface) may be provided on the inner wall of the cleaning container and / or a part of the surface of the stirring member to remove resin fragments. Remove foreign matter from the surface (brush or scrape). Water or water / synthetic cleaning solution can be supplied to the container to enhance the removal of foreign substances. 516996

The remote grinding surface (the rough surface) can have any structure, as long as the surface of the resin chip is cleaned in part. The polished surface is preferably?: It has a concave-convex body, and its depth is preferably from 40 to 2 micrometers. By bringing the tree shards into contact with a rough surface with such concavities and convexities, a material such as a film or a label that adheres to the surface of the resin shard can be filled with Y Brush or scrape to remove. If the depth of the concavo-convex body is less than micrometers, foreign matter cannot be sufficiently removed. Conversely, if the thickness exceeds 0 μm, the surface of the resin fragments will be excessively scrubbed, thereby reducing the percentage of resin recovery. The depth of the concavo-convex body is preferably 50 to 1 μm, and most preferably 60 to 500 μm. If the depth is within this range, the external mass will not be wiped off excessively, but it can be fully removed. In the device for successively cleaning the resin fragments, the resin fragments are continuously fed from the end of the month / month frozen valley, and conveyed in a direction in a cleaning container, for example, by a screw or other components And collected continuously from the other end of the container. If water or an aqueous solution is used in this device, the feeding of the water or the aqueous solution is also performed in the same manner, wherein the water or the aqueous solution is continuously fed from one end and / or the middle portion of the cleaning container, and The clean guest flows in the same direction and is collected continuously by the other end of the container. "When using water or an aqueous solution during m / 糸 operation, it is used as a lubricant between the resin fragments and the bumps to prevent the resin fragments from being scrubbed excessively 'and the cooling operation by water Inhibit the temperature rise of resin fragments to prevent resin fragments from melting.

And sorting and recycling devices 47a to 47c. The resin crusher 21 is used to crush resin molded products into fragments, so that 70% or more of the fragments have an equivalent diameter ranging from 1 to 50 mm = the resin molded products are crushed one by one And is packaged to the transport bag 25 connected to the resin: the crusher 21 at the lower part. Although the resin crusher 21 shown in the drawing performs the crushing operation in a single step, if the resin molding is too large to be introduced into a crusher having a normal size, the operation can also be divided into Two steps to proceed. For example, it can provide a crusher. One step is to roughly crush the resin molding, and the other step is to further crush the roughly crushed fragments into a range from j. Smaller fragments of equivalent diameter of 50 mm. The transport bag 25 is made of transparent polyethylene, and has a size of 23 cm in length, η cm in width, and a thickness of 40 m. Unless in the resin identification device 41 which will be described later: the identification of the resin fragments is hindered, the conveying bag 25 can also be opaque and made of materials other than polyethylene. In addition, the bag body may be a non-film type bag body. Here, a preferred embodiment of the crusher will be described as follows.

516996 A7 B7 5. Description of the invention (24) The crusher shown in the figure has a chain conveyor 220 (endless conveyor belt) and a pair of opposing walls 250 (opposing members). The chain conveyor belt 220 conveys objects carried on the connecting plate 221 by moving the connecting plate 221, wherein the connecting plate 221 is connected to a chain 225 driven by sprocket wheels 227, 227. The chain conveyor belt 220 is configured to incline downward toward the conveying direction (direction shown by the arrow in the figure), so as to introduce the polymer molded product introduced into the crusher from the material positioned above the crusher The port 232 is introduced into the crusher, and the molded product is carried on the connection plate 221 at the same time. As shown in FIG. 5C, a plurality of crushed edges 222 (in the figure, divided into two rows of eighteen edges each) are located on individual connecting plates 221 of the chain conveyor belt 220, and they have sharp ends. The part protrudes from the conveyor belt. In this regard, a crushing pin may be used instead of the crushing edge 222. The opposing wall 250 extends in the vertical direction and has a pair of opposing surfaces 255, which are arranged relative to the end in the conveying direction of the chain conveyor belt 220 (the left end in FIG. 3). Near the position of the opposing surface 255 closest to the chain conveyor belt 220 (near the lower end in the drawing), it is provided with a plurality of crushing edges 252, and its direction is toward the chain conveyor belt 220. In this regard, a crushing pin can also be employed in place of the crushing edge rim 252. As shown in FIG. 5, the crushed edge 252 on the opposite wall 250 and the crushed edge 222 on the chain conveyor belt 220 have different phases from each other without colliding with each other, even if the crushed edges are tied The same is true when it comes closest. A slit 256 is provided in the opposing wall 250 so that the tip of the crushing edge 222 on the chain conveyor 220 can enter the slit 256 even when the crushing edge 222 is closest to the opposing wall 250. At the same time, it will not collide with the opposite wall 250. Figure 4 shows -27- This paper size applies Chinese National Standard (CNS) A4 (210X 297 mm) 516996 A7 B7 V. Description of the invention (25) shows that the crushed edge 222 of the chain conveyor belt 220 is closest to the pair When the wall 250 is placed, the tip of the crushing edge 222 enters the state of the slit 256. In the crusher thus constituted, the polymer molded product introduced from the material introduction port 232 into the crusher and conveyed by the chain conveyor belt 220 is roughly roughened by the crushing edge 222 and the crushing edge 252. They are crushed, and at the same time, the chain conveyor belt 220 and the opposing wall 250 are pressurized at a position closest to each other. FIG. 6A shows a variation of FIG. 3. In the crusher shown in FIG. 6A, a guide 259 is provided at the lower end of the opposing wall 250. When the molded product conveyed by the chain conveyor belt 220 is flat and points in the vertical direction, this guide 259 can prevent the molded product from being separated from the compressed state by the chain conveyor belt 220 and the opposing wall 250. Out and to prevent it from falling without being sheared by the crushing edges 222 and 252, but not in this respect, although in the embodiment of FIGS. 3 and 6A, the chain conveyor 220 and the opposite The walls 250 each have crushed edges, however, crushed edges may be provided on only one of them. Of course, if both are provided, the cutting action of the crushed edge can be further strengthened. In the crusher shown in Fig. 6B, two chain conveyor belts 220 and 250a are provided so that the distance between the two becomes gradually smaller along the conveying direction. According to this crusher, the inclined chain conveyor 250a has a function of a pair of members. The crushing edges 222 and 252a provided on the individual conveyor belts 220 and 250 have different phases so that they do not collide with each other, even when the crushing edges are closest to each other. Although the two chain conveyor belts 220 and 250a shown in Fig. 6B have a pressure of -28-, this paper size applies the Chinese National Standard (CNS) A4 specification (210X 297 mm). 5. Description of the invention (26) Bang edge 222 252a, however, it is also possible to provide child-friendly slamming edges on at least one conveyor belt. If crushed edges are provided on both conveyor belts, the crushed edges "shear operation can cut more thoroughly. In the "shown", the upper chain conveyor belt 250a can be replaced by a belt with the same weaving: slope: inclined side walls. Alternatively, it can also provide roller conveyors that can be used for the conveyor belt device. To convey the polymer molding, and push it into the gap between the conveyor belt device and the opposing member, so that the molding is compressed at the same time as being compressed by a crushed edge or a pin. Being roughly crushed 'provides such a design that can fully exert its effect. In this regard,' by providing a fine crusher after the design shown in Fig. 3 or 6 (which can The crushed fragments are further crushed into smaller bangs), and a continuous system can be formed. Now refer to FIG. 2, in which the conveying device 49 is capable of transporting resin fragments at a predetermined speed: If you want to discriminate the resin because of the slower speed of the resin identification device 41 (to be described later), you can expect to lose the bag. === There is a need to pause. The conveying device may include a conveyer with an indulgence, and if the predetermined arrival time arrives, the corresponding tray will be tilted, and the bag body carried on it will be dumped to a position that is at its right ... The time required in the recovery box of the specific bag body with fat type A in which the resin towel A is packaged, plus the time required for the tree A in the bag body to endure for type A. The sum of the two time is This is the expected arrival time. The corresponding tray is on which the specific bag body is placed 297 mm.) This paper is a national standard (CNS) A4 specification -29- 516996. V. Description of the invention (27 months) Although the shredder 21 and the conveying device 49 (and the resin identification device η or other devices) are provided in the industrial waste shown in FIG. 2, the two devices may be separately located in different factories, so that The resin fragments crushed by the crusher 21 and stored in the bag body 25 can be sent to a factory in which a conveying device 49 or other device is provided. In other words, even in this design, it can still be Reduce the transportation cost because the volume of the resin that has been transported has been reduced. The resin identification device 41 is a device that identifies the type of resin fragments in the bag body based on Raman spectrum analysis. # That—the laser beam is irradiated to Pass (or, if it takes time to identify, it can be stopped at that position) a resin fragment in the bag body 25 at a detection position (identification position), and the light beam is reflected back from there. By so A beam of light can be obtained with the light beam, and then the spectrum is compared with the Lehman spectrum of a known resin to determine the type of resin in the bag. For this purpose, the resin identification device 41 is in advance The Lehman spectra of various resins are stored. The sorting and recycling device 47a is used for recycling the resin a. Similarly, the sorting and recycling device 4 7 b is used for recycling the resin B, and the sorting and recycling device 4 7 c is used for recycling the resin. C. If there are field or more types of resin, the number of sorting and recycling devices will be increased relatively. The distance between the sorting / recycling position of the sorting and recycling device 4 7 a and the detection position of the resin identifying device 41 It is marked with & and the distance between the sorting / recycling position of the sorting and recycling device 4 7 b and the detection position of the resin identifying device 41 is marked with b; and the sorting in the sorting and recycling device 4 7 c The distance between the recovery position and the detection position of the resin identification device 41 is marked with c. When the current time has reached the scheduled arrival -30 This paper size applies to China National Standard (CNS) A4 specification (210X 297 mm) ) ^ 16996

After a while, the sorting and recycling device corresponding to the type of resin that meets the predetermined arrival time will start to recover the bag body located in the sorting / recycling position of the sorting and recycling device into the recycling box.

The sorting and recycling device is not limited to the one shown in the figure, in which one of the conveyor belt's tiltable trays can pour the bag into a recycling box arranged directly under the conveyor belt. For example, a manipulator can be provided above the conveyor belt, which can lift the bag on the conveyor belt and retrieve it. Alternatively, "a pusher may be provided" to push the bag on the conveyor belt to the side by a rod or the like. Alternatively, the sorting and recycling device is not provided separately for the type of resin. Conversely, all bags can also be recycled by a single-recycling device, and the device can be used to distribute the bag body to the resin type In individual recycling bins. Order

The description of the invention (Μ) The tree stalk is a type A, then the distance is a to the sorting and recovery device 4 7 & ), And the conveying speed v of the conveying device 49; the pre-arrival arrival time thus obtained is stored in a memory (not shown) corresponding to the controller 45 of the resin type A (that is, the sorting and recycling Device 47 昀 (S 1 3). In view of this, since the conveying speed v and distance (a / b / c) are known, the time required for conveying according to the type of resin plus the current time can be obtained. The result of the above calculation is obtained. The right eye has reached the pre-arrival arrival time stored in the memory (not shown) of the controller 45 (that is, if the result in step S21 is illusory, the operation instruction is changed from The controller 45 sends to the sorting and recycling device stored in accordance with this predetermined arrival time. Thus, the above sorting and recycling device can be operated to recycle the bag body (S 2 3). After that, the arrival time is far enough and stored in the corresponding classification back The data in the device can be deleted from the memory (s 2 5). Other preferred embodiments of the resin identification device will be described in more detail with reference to FIGS. 9 to n. (1) First embodiment 9A, 9B and 10 are diagrams schematically showing a first embodiment of a polymer conveying mechanism having an identification device, in which FIG. 9A is a side view, FIG. 9B is a top view, and FIG. 10 is a A cross-sectional view taken along section line 10_1 () in Fig. 9A. In these drawings, the component number 4 丨 〇 indicates a polyethylene bag (which has a length of 23 cm, a width of 17 cm, and a width of 4 cm). 〇micron thick size), which has a suitable size (for example, 70/0 or more fragments are equivalent diameter ranging from 1 to 50 mm) resin fragments are packed in the bag _______ ^ The paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) ^--516996 A7 B7 V. Description of the invention (30) In the body, the equivalent diameter is the same as the projected area of the object The diameter of the circle. The bag body 410 is transported on a conveyor belt 440 in the direction of the arrow, where The conveyor belt 440 is driven by the driving rollers 441 and 441, and is irradiated with a laser beam emitted from a sensor element 421 at the center of its moving path, thereby detecting a Raman scattering The detected signal is fed to an identification and calculation device 420-, and the type of resin is identified in the device. That is, the detected Raman spectrum can be stored sequentially and in advance. Compare the spectra of various conventional resins until it is found that the conventional resin matches the resin to be identified. Based on the results of the identification, the timing of the dispensing operation can be calculated, and according to the calculated timing, Run the distribution operation. Thereby, the bag body 410 can be removed from the conveyor belt 440 and put into a container (regardless of the containers 435a, 435b, and 435c) corresponding to the identified resin type. The allocation timing is that the Raman scattering of the bag body 410 has identified the resin type at the sensor element 421 and reached the container (one of the containers 435a, 435b, and 435c) corresponding to the resin type packed in the bag body. . According to the first embodiment, as shown in the figure, a plurality of slits 400S with a predetermined length are used as a light window so that light can penetrate the window (· It has a width of 10 mm and a length of 20 cm Size), the plurality of slits are arranged at predetermined intervals along the center of the width of the conveyor belt 440 in the conveyor belt conveying direction. The above-mentioned sensor element 421 is disposed in a position corresponding to the slit position, directly below the conveyor belt 440, and near the inner surface of the conveyor belt 440. With this, it can combine the light receiving part of the sensor element 421 with the bag body -33- This paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) 516996 A7 B7 V. Description of the invention (31) 410 The distance between the bottom surfaces is always kept at a predetermined shorter distance (for example, about 10 mm), and the Raman scattering can be detected regardless of the shape of the bag body 410. This enables high-precision resin identification. In view of this, a member can be provided at a position above the sensor element 421 to press the bag body 410 against the upper surface of the conveyor belt 440 to prevent the bottom surface of the bag body 410 from floating from the upper surface of the conveyor belt 440. The distance between the light receiving portion of the sensor element 421 and the bottom surface of the bag body 410 can be kept constant. (2) Second Embodiment FIG. 11 is a schematic view showing a second embodiment of a polymer conveying mechanism, in which FIG. 11A is a side view, and FIG. 1B is a top view. In these drawings, the same component numbers as those in FIG. 9 are used to indicate the same or similar components, and the description of these components will not be repeated. According to the second embodiment, as shown in the figure, a window plate 422 having a light window through which light can pass is arranged on the lateral side of a conveyor belt 440a, and it can be used as a stop member. A sensor element 421 is positioned on the side of the window plate 422 opposite to the conveyor belt 440a, so that the light receiving portion of the sensor element 421 is directly facing the window plate 422. At a position relative to the window plate 422, a plate-shaped curved guide 423 is positioned directly above the conveyor belt 440a, and the conveyor belt is inserted between the window plate and the curved guide. The guide 423 can push the bag body 410 on the conveyor belt 440a toward the window plate 422, and make the bag body 410 contact the window plate 422. According to this structure, the light receiving part of the sensor element 421 and the horizontal side of the bag body 410 can be used. -34- This paper size applies to China National Standard (CNS) A4 (210 X 297 mm) 516996 A7

The distance between the faces is maintained at about the thickness of the window plate 422 (for example, about ιm mm) 'regardless of the shape of the bag body 41G. In other words, it can keep the distance value as small as possible so that it can detect the Raman scattering. This enables high-precision resin identification. One or two or more rollers can replace the guide 423 formed by the curved plate as shown in the figure to achieve the same purpose. In this example, the drum may be a free-rotation type or may be rotated in synchronization with the conveyor belt 44a. μ Although an endless conveyor belt is used as the conveyor belt device in the above embodiment, the conveyor belt device according to the present invention should not be limited to the endless conveyor belt, as long as it can convey the polymer to be detected, and at the same time It is sufficient that a predetermined short distance is maintained between the sensor element 421 < light receiving portion and the polymer. For example, the conveyor device can also be of the type used to transport the bag body 410 carried on a pallet. [2] Cleaning system 600 Next, the cleaning system 600 will be described. Figures 12 to 14 show the structure of a continuous cleaning device 600, of which Figure 2 is a schematic cross-sectional view, Figure 13 is a schematic side cross-sectional view, and Figure 14 is a discharge for adjusting the water level. Tube 669. The continuous cleaning system 600 has a container 660 and a rotating body 662. In Figs. 12 and 13, the container 660 may be made of a metal such as stainless steel. One end of the wall body above the container 660 is provided with an introduction port 663 through which resin fragments can be introduced, and a discharge port 668 for discharging resin fragments is provided in the lateral wall body on the side of the opposite end. A water inlet 664 is located in at least one position on the wall above the volume 5 | 660, and a drainage hole 666 is located in the ________- 35- This paper size applies to China National Standard (CNS) A4 specifications (210 X 297 mm)

Hold

516996 A7 B7 5. Description of the invention (33) At least one position of the wall below the container 660. A drain pipe 669 for adjusting the water level is connected to the drain hole 666. A predetermined amount of resin chips are continuously introduced into the container 660 through the introduction port 663, and are conveyed along the introduction port 663, and discharged through the discharge port 668. Preferably, in this procedure, the introduction speed of the resin chips is substantially equal to each other, and is kept substantially constant. The feeding speed of the water to be entered through the water inlet hole 664 is preferably controlled so that the water level determined by the water level adjusting pipe 669b is maintained, and the water overflows from the open end of the water level adjusting discharge pipe 669. The speed is taken into account. By adjusting the introduction and discharge of resin fragments, a fixed amount of tree, grease fragments and water can be continuously transported through the container 660. Therefore, the resin fragments can be cleaned evenly, and therefore, foreign matter can be prevented from remaining on the surface of the resin fragments, and the surface can be prevented from being excessively scrubbed. A slit or a stamped plate is arranged in the drainage hole 666 of the bottom wall of the container 660 or other wall body. Furthermore, in the drainage hole 666, the water level adjusting and discharging pipe 669 has a drainage pipe 669a which is connected to the drainage hole 666 and stands upright on the lateral side of the container 660 and has a water level adjusting pipe 669b. It slides into the drain pipe 669a. An O-ring seal 669c is inserted between the inner surface of the discharge pipe 669a and the outer surface of 66% of the water level adjustment pipe to maintain a liquid-tight seal. By moving the water level adjusting pipe 66% up and down, it can adjust the water level in the cleaning system 600 and maintain a predetermined water level. Although the water inlet hole 664 and the water drainage hole 666 are respectively provided at one position in the illustrated embodiment, they may be provided at a plurality of positions respectively.当 -36- This paper size applies Chinese National Standard (CNS) A4 (210X 297 mm) 516996 A7 ______ B7 V. Description of the invention (34) The water inlet 664 is located in the plural from one end to the other end of the container 660 When in position, it can quickly guide the dust or other substances generated by the cleaning operation to the drainage hole 666, and discharge it to the outside through the water level adjustment discharge pipe 669. Furthermore, it prevents dust or other substances from sticking to the resin fragments again. The openings in the drainage holes 666, such as the slits or openings of a stamped plate, are sized to allow water or dust to pass through, but to prevent resin fragments from passing through. In view of the structural strength, the size range of the slit is preferably from about 0.3 to 2 mm. Although the drainage hole 666 can be located on the bottom wall or the side wall ', it is preferable that the drainage hole is located on the bottom wall because of the water level adjustment. In view of this, if the drainage hole is located on the horizontal wall, its position is naturally as low as possible. 66% of the open end of the water level adjusting pipe is open to the outside, so that the water level in the container 66 may be approximately equal to the height of the 66% of the open end of the water level adjusting pipe. With this, even if the feed rate of water is changed, the water level can be kept fixed, and excessive water can be discharged from 66% of the open end of the water level adjusting pipe. The discharged water can be accumulated in a water tank, and after being extracted and filtered by a filter to remove dust or other materials, it can be reused. The rotating body 662 is provided with a spiral blade ⑽, which is used to clean the resin fragments, and at the same time, the fragments are transferred from the guide ⑹ to the discharge port 668, and has a cleaning plate 662a and a cleaning pin 以 to wipe the surface of the resin fragments Brushing or scraping the external material and applying vibration force on the surface at the same time, all of these components can be replaced. Children's cleaning board 662a or cleaning pin 6 must be one of the two. Paper size is suitable for financial @ @ 家 标准 (CNS) Mq χNou read ----- 5. Description of the invention (35) A series can be eliminated, but its cooperation Use is better. The diameter of the spiral blade paper, the thickness of the cleaning plate 662a, and the length of the cleaning pin are not limited as long as it can achieve the purpose of effective cleaning. The helical blade 662c can have approximately the same diameter; the arm plate can have approximately the same diameter and thickness C, and the clear 662b has approximately the same length. Furthermore, it is used to clean the resin fragments and transfer them at the same time. The number of spiral blade greens of the fragment is provided in two or three in the outermost region. In each region, the length of the cicada, the female one, e θ LA, and the axial length of the spiral piece 662c are taken relative to the diameter of 0.5 to 3 times. Although these spiral blades 662c, cleaning plates 6623, and cleaning pins 662b can be alternately arranged, the number in each area can be the same as or different from the other areas. The distance between the spiral blades 662c must consider the rotation axis Rotation speed of the rod. Because the rotating shaft rod system must be able to rotate at a relatively high speed in order to: grind and clean the resin fragments, the distance is preferably in the range of ㈣ to: where D represents the spiral blade • Diameter. If the distance is less than 0.04, the gap between two adjacent spiral blades will be too small: Resin fragments may be expected to enter the gap, and the spiral blades will move. If it interferes with it or "Operation 4, the scale m gap resin fragments may be dazzled, and the cleaning operation cannot be continued. On the other side, if the distance exceeds L5D", the transport efficiency will decrease. The conveying efficiency is too large, so that the resin is broken = the residence time of the plate 662a or the cleaning pin 66 in the area is not too long. Some of the spiral blades 662c will be truncated, so that the The balance can be adjusted. M ,, This paper size itffi Chinese National Standard (CNS) A4 specification (2ιOX 297 male I) • 38 516996

The shape of the cleaning plate 662a is not limited. For example, when viewed from the axial length direction of the rotating shaft 662, the cleaning plate may be round or angular, such as a triangle or a quadrangle. The cleaning plate 662a is not necessarily symmetrical in shape with respect to the rotation shaft 662. Furthermore, it can be tilted to the rotation shaft 662 to make it have a conveying function. The cleaning plates inclined in the conveying direction and the opposite direction can cooperate with each other to enhance the cleaning efficiency. The same result also appears in the cross-sectional shape of the cleaning pin 662b, where the cleaning pin may be circular or polygonal, such as a triangle or a quadrangle. It is best to use a polygonal cross-sectional shape because cleaning efficiency can become higher. The cleaning pin 662b does not necessarily protrude perpendicularly to the circumference of the rotating shaft 662, and may also be inclined at an appropriate angle. The rotation speed of the rotating shaft 662 can have a proper range of variation according to the size of the device, the type of resin fragments, or the required degree of cleaning. One by one, the linear velocity of the tip of the cleaning plate 662a or the cleaning pin 662b is preferably within a range of 0.5 to 20 m / s, and more preferably from 1 to 10 m / s. At a rotational speed of less than 0.5 m / s, it is impossible to sufficiently clean the surface of the resin chip even if the processing time is extended. If the linear velocity exceeds 20 meters / second, the internal temperature of the cleaning device will rise and soften and tend to melt the resin fragments. This situation is quite unfavorable because it will cost Large driving power. At least part of the surface in contact with the resin fragments; that is, the inner surface of the container 66Q and the surfaces of the spiral blades 662c, the cleaning plate 662a, and the cleaning pin 66; need to be roughened to form an abrasive surface. Thereby, foreign matter on the surface of the resin chip can be effectively wiped or scraped off. _ -39- This paper size applies to China National Standard (CNS) A4 (210 X 297 mm)

Pretend

516996 A7 B7 V. Description of the invention (37) The depth of the asperities on the roughened surface is preferably in the range of 40 to 2000 microns, and more preferably 50 to 1000 microns, if it is 60 to 500 microns is the best. If the depth is less than 40 microns, the foreign matter may not be sufficiently removed. Conversely, if it exceeds 2000 micrometers, the surface of the resin fragments may be excessively brushed without unduly reducing the percentage of resin recovery. The degree of surface roughening described above does not necessarily need to be fixed within the range from the inlet 663 to the outlet 668. The cleaning efficiency can be adjusted, for example, by changing the coarse sugar content so that it is thicker toward the introduction port 663, and smoother toward the discharge port 668. Furthermore, for example, by mixing various abrasives with water, the cleaning efficiency can be further improved. Although a cleaning device of a twin-shaft type is shown in the drawings, this is only an example, and a single-axis or multi-axis cleaning device may be used. However, when a uniaxial device is used, the movement of the resin fragments becomes unidirectional, thereby reducing the cleaning efficiency. Conversely, devices with three or more shafts can complicate the structure and increase costs. The internal space of the cleaning device can be appropriately designed according to the output or other factors. The internal space of the container 660 in a direction perpendicular to the rotation shaft 662 must be appropriately selected in accordance with the diameter of the spiral blade 662c and the clearance required between the inner surface of the container 660 and the tip of the spiral blade 662c. The axial dimension of the rotating shaft 662 is 5 to 30 times the diameter of the spiral blade 662c, and preferably 10 to 30 times the diameter of the spiral blade 662c.
