Description

Technical Field

[0001] This invention relates to the field of polymer processing technology, specifically to a processing equipment for preparing recycled composite materials from waste plastics. Background Technology

[0002] Shape memory polymers are a type of widely studied smart material that can generate actions or certain prescribed responses after being stimulated by heat, machinery, magnetism or electricity, restoring its original shape or technical parameters, such as shape, position, strain, natural frequency, stiffness, damping, friction, and other static and dynamic properties.

[0003] Waste plastics mostly consist of unevenly shaped blocks, bottles, and strips (such as medicine bottles, water bottles, plastic stool legs, and plastic connectors). If waste plastics are discarded haphazardly without proper treatment, they will not degrade due to the nature of plastics and will only cause serious pollution to soil and water sources. Therefore, waste plastics are now collected and recycled. After being granulated, waste plastics undergo asynchronous processing. The composite material processing flow is as follows: raw material granules are heated, melted, and extruded through a screw extruder; the molten material is filtered; and the filtered material is spun into fibers. During the filtration process, melt filter cartridges are generally used. Existing melt filter cartridges are mostly made of sintered stainless steel fiber felt and folded stainless steel woven mesh. Multiple filter cartridges are assembled within a single filter cylinder, and multiple cartridges can work simultaneously for filtration. After prolonged use, impurities will clog the filter cylinder pores, so the filter cartridges need to be cleaned frequently.

[0004] The existing cleaning method involves disassembling all individual filter elements one by one and then performing ultrasonic cleaning or high-pressure water washing. However, the above-mentioned multi-filter structure also has certain defects. During cleaning, only the outer surface of the filter element is exposed within the cleaning interface, but some impurities adhere to the inner surface of the filter element. In contrast, the inner surface of the filter element in the existing technology cannot be exposed, resulting in incomplete cleaning of its inner surface. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a processing device for preparing recycled composite materials from waste plastics, which solves the problem that the inner surface of the filter element cannot be exposed in existing technologies, resulting in incomplete cleaning of its inner surface.

The number of pull ropes at the bottom is equal to the number of winding posts, and one end of the lower pull rope is fixed to the second winding rod, while the other end is fixedly connected to a connecting rope wound around the lower part of the winding post.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0023] The following is based on Figure 1 - Figure 17 This invention describes a processing equipment for preparing recycled composite materials from waste plastics, provided in an embodiment of the invention.

[0024] Please see Figure 1 As shown, this embodiment of the invention provides a processing equipment for preparing recycled composite materials from waste plastics, including a housing 100 and a filter mechanism 300 located inside the housing 100. The housing 100 includes a shell 130, a bucket-shaped shell 120 is fixed to the top of the shell 130 by bolts, a feed pipe 140 is provided on one side of the shell 130, and a discharge pipe 110 is installed above the bucket-shaped shell 120. The filter mechanism 300 is actually housed inside the shell 130.

[0025] During use, the material extruded from the extruder passes through the metering pump and enters the feed pipe 140, where it is filtered by the filter mechanism 300. After filtration, it enters the hopper shell 120 and is discharged from the discharge pipe 110.

[0026] The funnel-shaped shell 120 and the shell 130 should be connected by a flange so that they can be fixed and disassembled to facilitate the removal of the internal filter mechanism 300 for cleaning.

[0027] Combination Figure 1 - Figure 9 As shown, the above-mentioned filtration mechanism 300 includes a column 380, a support cage 360, a filter body 320, and a winding column 390.

[0028] The column 380 is located on the inner axis of the outer shell 100, and the support cage 360 ​​is evenly fixed on the outer surface of the column 380. The column 380 is a mesh structure with open areas, which serves as a carrier to support the filter body 320. The filter body 320 is a planar flexible filter component in the unassembled state. During assembly, the planar flexible filter component is surrounded along the outer surface of multiple sets of support cages 360, and detachable fixing components are provided at both ends of the planar flexible filter component. After the enclosure is completed, the planar flexible filter component is formed into a closed filter component (i.e., the filter body 320) by the detachable fixing components. The material to be filtered enters the shell 130 through the feed pipe 140 and can pass through the filter body 320, so that the filter body 320 filters the material. The filtered material then enters the interior of the filter body 320.

[0029] The filter body 320 can also be removed and reformed into a planar flexible filter component via a detachable fixing component.

[0030] To ensure that the filter body 320 can fit tightly against the outer surface of the support cage 360, the winding column 390 is located between the two sets of support cages 360. The winding column 390 can apply pressure to the filter body 320 along the radial direction of the column 380, so that the filter body 320 fits against the outer surface of the support cage 360, thus ensuring the shape of the filter body 320.

[0031] Therefore, the processing equipment for preparing recycled composite materials from waste plastics provided in this embodiment of the invention can replace the original single cylindrical filter with a whole planar flexible filter component, and make the planar flexible filter component enclose to form a filter body 320. Thus, after the entire filter body 320 is disassembled, it is a planar structure, so the inner surface of the filter body 320 can also be fully exposed, thereby making its cleaning more thorough and comprehensive.

[0032] Optionally, the support cage 360 ​​can be circular, square, or similar in shape. Figure 7 The cam shape shown.

[0033] like Figure 2-5 As shown, the aforementioned filter mechanism 300 also includes a first assembly plate 310 and a second assembly plate 330 to maintain the stability of the column 380.

[0034] The first assembly tray 310 is fixed to the upper end of the column 380, and the lower surface of the first assembly tray 310 is provided with a first assembly groove 312 for accommodating the upper edge of the filter body 320. The upper end of the support cage 360 ​​is located in the first assembly groove 312, and a sealing gasket is fixed at the bottom of the first assembly groove 312. Therefore, the support cage 360 ​​and the bottom of the first assembly groove 312 are sealed, thereby preventing material from entering the support cage 360 ​​from the upper end of the first assembly groove 312.

[0035] The second assembly tray 330 is located at the lower end of the column 380. The column 380 is detachably mounted on the second assembly tray 330 so that the column 380 can be separated from the second assembly tray 330 (this facilitates the separation of the second assembly tray 330 from the first assembly tray 310). The second assembly tray 330 has a second assembly groove 332 for accommodating the lower edge of the filter body 320. The lower end of the support cage 360 ​​is located in the second assembly groove 332. A sealing gasket is fixed at the bottom of the second assembly groove 332, so the support cage 360 ​​and the bottom of the second assembly groove 332 are sealed, thereby preventing material from entering the support cage 360 ​​from the lower end of the second assembly groove 332.

[0036] Preferably, a discharge hole 311 is provided on the first assembly plate 310 at a position opposite to the hollow space of the filter body 320 along the axial direction, so that the material filtered by the filter body 320 can be discharged from the discharge hole 311.

[0037] like Figure 3 , Figure 5 - Figure 7 To further improve the tightness between the upper and lower sides of the filter body 320 and the support cage 360, and to prevent material from directly entering the support cage 360 ​​through the gap between the upper and lower sides of the filter body 320 and the support cage 360, a pressing component 370 and a tensioning component are also provided. The pressing component 370 is located in the first assembly groove 312 and includes pressing rods 371. The pressing rods 371 are evenly distributed on the outer edge of the first assembly groove 312, and the upper end of the pressing rods 371 is fixed to the bottom of the first assembly groove 312 (the bottom of the groove refers to the upper surface of the first assembly groove 312). Multiple pressing rods 371 are connected in series by connecting ropes 372. The tensioning component is installed at the axial position inside the housing 100 and is used to apply tension to the connecting ropes 372.

[0038] Therefore, in this embodiment, when the tensioning component applies tension to the connecting rope 372, it can press the upper edge of the filter body 320 against the outer wall of the support cage 360, thereby sealing the upper edge of the filter body 320 with the support cage 360 ​​and preventing material from directly entering the support cage 360 ​​from the gap between the upper side of the filter body 320 and the support cage 360.

[0039] Preferably, the compression bar 371 is an elastic component, such as a rubber column or an elastic steel column.

[0040] Preferably, the portion of the upper end of the support cage 360 ​​inserted into the first assembly groove 312 is a non-perforated area, thereby further improving the fit between the upper end of the support cage 360 ​​and the filter body 320 and further preventing material leakage.

[0041] It is worth noting that, such as Figure 10and Figure 11 The aforementioned pressing component 370 is also disposed in the second assembly groove 332, so that when the tension component is working, the lower end of the filter body 320 can also be pressed and adhered to the outer wall of the support cage 360, preventing material from directly entering the support cage 360 ​​from the gap between the lower side of the filter body 320 and the support cage 360.

[0042] Specifically, the pressure rods 371 are evenly arranged on the outer edge of the second assembly groove 332, and the upper end of the pressure rods 371 is fixed to the bottom of the second assembly groove 332 (the bottom of the groove refers to the lower surface of the second assembly groove 332). Multiple pressure rods 371 are connected in series by connecting ropes 372.

[0043] Preferably, the portion of the lower end of the support cage 360 ​​inserted into the second assembly groove 332 is a non-perforated area, thereby further improving the fit between the lower end of the support cage 360 ​​and the filter body 320 and further preventing material leakage.

[0044] Combination Figure 4 - Figure 7 As shown, to achieve the function of the aforementioned tension assembly, it includes a first winding rod 352, a second winding rod 355, and a pull rope 353. The first winding rod 352 is rotatably mounted in the axial direction within the first assembly plate 310, and is also rotatably connected to the column 380. The upper pull ropes 353 are arranged within the first assembly plate 310, and the number of upper pull ropes 353 is equal to the number of winding columns 390. One end of the upper pull rope 353 is fixed to the first winding rod 352, and the other end is connected to the winding column 380. The connecting rope 372 above 0 is fixedly connected; in this embodiment, when the first winding rod 352 rotates, it can wind up the pull rope 353. When the pull rope 353 is wound up, it can apply tension to the connecting rope 372, thereby achieving the purpose of pressing the pressure rod 371 onto the filter body 320 (in fact, the amount of winding of the pull rope 353 is small, the movement tendency of the pressure rod 371 is also small, and the pressure rod 371 is between pressing and not pressing, but even in the unpressed state, there is no gap between the pressure rod 371 and the filter body 320).

[0045] Additionally, it is worth noting that the second winding rod 355 is rotatably mounted in the axial direction within the second assembly disc 330. The number of lower pull ropes 353 is equal to the number of winding posts 390. One end of the lower pull rope 353 is fixed to the second winding rod 355, and the other end is fixedly connected to the connecting rope 372 wound around the winding post 390. In this embodiment, when the second winding rod 355 rotates, it can wind up the pull ropes 353. When the pull ropes 353 are wound up, they can apply tension to the connecting rope 372, thereby achieving the purpose of pressing the pressure rod 371 onto the filter body 320.

[0046] More importantly, such as Figure 6and Figure 9 In essence, the upper edge of the winding section of the filter body 320 on the winding column 390 is lower than the height of the support cage 360, and the height of the winding section on the lower edge of the support cage 360 ​​is higher than the winding column 390. That is, the upper and lower parts of the support cage 360 ​​protrude from the upper and lower sides of the winding part of the filter body 320. In other words, clearance grooves 321 are opened on the upper and lower sides of the filter body 320 on the winding column 390 (the clearance grooves 321 here are the...). Figure 15 The rubber edging 324 has a clearance groove 321, and the upper end of the winding post 390 is also provided with an extension post 391 with a diameter smaller than the winding post 390, so that the connecting rope 372 is wound around the extension post 391, and the pull rope 353 passes through the clearance groove 321 to apply tension to the connecting rope 372; in summary, the clearance groove 321 here is to make way for the pull rope 353.

[0047] Combination Figure 12 - Figure 14 As shown, in order to achieve synchronous rotation of the first winding rod 352 and the second winding rod 355 to tighten or release the pressure rod 371, the lower end of the first winding rod 352 passes through and extends to the lower end of the column 380, and a connector 358 is fixedly provided at the lower end of the first winding rod 352. A rotating disk 357 is fixedly provided at the upper end of the second winding rod 355. A protrusion 354 is provided on the upper surface of the rotating disk 357, and a groove 359 adapted to the protrusion 354 is provided on the lower surface of the connector 358, so that the rotating disk 357 rotates when the first winding rod 352 rotates. In this embodiment, when the first winding rod 352 rotates, it can drive the rotating disk 357 to rotate through the connector 358, the protrusion 354 and the groove 359, thereby driving the second winding rod 355 to rotate synchronously, so as to achieve the purpose of synchronous tightening or release of the upper and lower sets of pressure rods 371.

[0048] Combination Figure 5 and Figure 6 As shown, in actual use, it is also necessary to limit the rotation of the first winding rod 352 and the second winding rod 355 to ensure the force applied by the first winding rod 352 and the second winding rod 355 to the pull rope 353. The tension component here also includes a threaded cylinder 350. A threaded hole 313 is provided in the middle of the upper surface of the first assembly plate 310. The threaded cylinder 350 is threaded into the threaded hole 313. The upper end of the first winding rod 352 is a hexagonal prism. The lower surface of the threaded cylinder 350 is provided with a hexagonal groove for the hexagonal prism to be inserted, so that when the threaded cylinder 350 rotates, it drives the first winding rod 352 to rotate. The length of the hexagonal groove can compensate for the vertical displacement of the threaded cylinder 350.

[0049] That is, by rotating the threaded cylinder 350, the first winding rod 352 can be driven to rotate. When the first winding rod 352 rotates, the pull rope 353 can be wound up. Of course, during the rotation of the threaded cylinder 350, it will also move axially along the threaded hole 313. At this time, the hexagonal column can generate axial relative displacement with the hexagonal groove. The threaded cylinder 350 is in a self-locking state in the threaded hole 313 to ensure the locking of the first winding rod 352 and the second winding rod 355, and to ensure the force applied by the first winding rod 352 and the second winding rod 355 to the pull rope 353.

[0050] Preferably, a handle 351 is fixed on the upper surface of the threaded cylinder 350 to facilitate manual rotation of the threaded cylinder 350.

[0051] like Figure 15 and Figure 16 As shown, the filter body 320 mentioned above includes individual felts 322, and multiple individual felts 322 are provided. Multiple individual felts 322 are connected in series to form stainless steel fiber sintered felt, and the stainless steel fiber sintered felt is folded into a corrugated stainless steel fiber sintered felt. This type of filter element has a large filtration area and good filtration effect. The reason for dividing a whole stainless steel fiber sintered felt into multiple individual felts 322 is to avoid the situation where the entire stainless steel fiber sintered felt needs to be replaced if a certain part of the stainless steel fiber sintered felt is damaged. By using the form of individual felts 322 connected in series, only the corresponding individual felt 322 needs to be replaced when a certain part is damaged.

[0052] Preferably, a first flexible edging 323 is fixed on both sides of each individual felt 322, and two adjacent first flexible edgings 323 are fixedly connected.

[0053] Optionally, the first flexible edging 323 here is made of polyester fiber, carbon fiber or glass fiber.

[0054] Optionally, the two adjacent first flexible edgings 323 can be fixed by sewing, strong adhesive bonding or Velcro connection.

[0055] like Figure 16 In order to maintain the wavy shape of the individual felt 322, a stringing rope 327 is also provided. The stringing rope 327 is used to string the upper side and the lower side of the individual felt 322 (the stringing here means that the stringing rope 327 passes through each layer of the wave), thereby maintaining the wavy shape of the individual felt 322.

[0056] like Figure 15Preferably, a rubber edging 324 is also provided, which wraps around the upper and lower edges of the corrugated stainless steel fiber sintered felt. The pressure rod 371 presses the rubber edging 324 tightly. The use of the rubber edging 324 has two advantages: First, compared with no edging, the rubber edging 324 makes it easier to insert the stainless steel fiber sintered felt into the first assembly groove 312 and the second assembly groove 332; Second, when the rubber edging 324 is used, the pressure rod 371 actually presses the rubber edging 324 tightly against the outer wall of the support cage 360. Due to the continuity and impermeability of the rubber edging 324, it can fit more tightly with the support cage 360, further avoiding material leakage.

[0057] like Figure 15 To facilitate the disassembly of the filter body 320, the aforementioned detachable fixing component has through holes 325 arranged along the height direction on the first flexible edging 323 at both ends of the planar flexible filter component, and the through holes 325 on the two first flexible edging 323 are connected by fastening ropes 326.

[0058] Preferably, the fastening rope 326 is spirally passed through each through hole 325.

[0059] Of course, the detachable fixing components can also be other structures, such as using Velcro, zippers, etc., but all of them must be high-temperature resistant zippers and high-temperature resistant Velcro.

[0060] like Figure 1 , Figure 2 and Figure 17 As shown, in order to facilitate the removal of the entire filter mechanism 300 from the housing 130 at once, the filter mechanism 300 here also includes a connecting structure 340, which includes a rotating ring 341 and a threaded ring 343. The outer surface of the first assembly plate 310 is provided with a groove 314 along the circumferential direction. The rotating ring 341 is rotatably installed in the groove 314, and the outer edge of the rotating ring 341 protrudes from the outer edge of the first assembly plate 310. The rotating ring 341 can be rotated inside the groove 314 by manually rotating the rotating ring 341.

[0061] The threaded ring 343 is fixed below the rotating ring 341 by the connecting rod 342. The second assembly plate 330 is provided with an internal thread 331 that is adapted to the threaded ring 343, so that the relative position of the first assembly plate 310 and the second assembly plate 330 is locked, and the entire filter mechanism 300 can be directly removed from the housing 130.

[0062] In addition, the processing equipment for preparing recycled composite materials from waste plastics provided in this embodiment of the invention is also equipped with a pressing component 200. The pressing component 200 can provide a downward pressure on the entire filter mechanism 300, thereby maintaining the stability of the filter mechanism 300 within the housing 130 on the one hand, and pressing down the first assembly plate 310 on the other hand, improving the tightness of the first assembly plate 310 and the second assembly plate 330, and avoiding material leakage.

[0063] Specifically, the pressing component 200 includes a fixing ring 210 fixed to the lower surface of the bucket-shaped shell 120 and a pressing ring 230 fixed below the fixing ring 210 by a connecting rod 220. The pressing ring 230 squeezes the rotating ring 341 so that the upper and lower ends of the support cage 360 ​​are respectively attached to the first assembly groove 312 and the second assembly groove 332, thereby further preventing material leakage.

[0064] When using (working), in Figure 1 In the indicated state, the feed pipe 140 is connected to the metering pump, and the discharge pipe 110 is connected to the nozzle. The molten raw material enters the housing 130 through the feed pipe 140 and is filtered through the filter body 320. The filtered material can enter the bucket-shaped shell 120 through the discharge hole 311 and enter the nozzle through the discharge pipe 110. The material entering the nozzle can be ejected from the spinneret to form fibers.

[0065] After prolonged use of this device, the internal filter body 320 needs to be cleaned. The specific procedure is as follows: By removing the upper funnel-shaped shell 120 and using the handle 351 to remove the entire filter mechanism 300 from the housing 130, and then rotating the handle 351 in the first direction, the threaded cylinder 350 is rotated and moved axially along the threaded hole 313. Simultaneously, the threaded cylinder 350 drives the first winding rod 352 to rotate. The first winding rod 352, through the connector 358, protrusion 354, groove 359, and rotating disk 357, drives the second winding rod 355 to rotate. The first winding rod 352 unwinds the upper set of pull ropes 353, and the second winding rod 355 unwinds the lower set of pull ropes 353. Thus, neither the upper nor lower pressure rods 371 are pressed against the upper or lower sides of the filter body 320, allowing for easy removal of the filter body 320. Specifically, removal is achieved through the detachable fixing components. After removing the detachable fixing components, pulling the filter body 320 causes it to detach from the support cage 360, forming... Figure 15 The planar flexible filter component shown here allows all parts of the filter body 320 to be exposed, making it easy to clean and ensuring thorough and comprehensive cleaning.

[0066] In addition, by manually rotating the rotating ring 341, the threaded ring 343 can be disengaged from the internal thread 331 by the connecting rod 342, and the second assembly plate 330 can be exposed separately for cleaning.

[0067] After cleaning and drying, the filter body 320 needs to be reinstalled. The specific steps are as follows: The planar flexible filter element is wound along the support cage 360 ​​and the winding column 390. Figure 5 As shown in the diagram, manually adjust the position of the rubber edging 324 so that the upper rubber edging 324 enters the first assembly groove 312 and is located between the support cage 360 ​​and the pressure rod 371, and the lower rubber edging 324 enters the second assembly groove 332 and is located between the support cage 360 ​​and the pressure rod 371. At this time, rotate the handle 351 in the opposite direction so that the threaded cylinder 350 can rotate in the opposite direction and wind up the pull rope 353. At this time, the pull rope 353 can apply tension to the connecting rope 372, so that each pressure rod 371 can press the rubber edging 324 tightly into the non-perforated area of ​​the support cage 360. This is to put the entire filter body 320 back in place.
