Description

Technical Field

[0001] This invention relates to the field of environmentally friendly fiber melt technology for processing waste textiles and waste textile fibers, and particularly to an environmentally friendly waste fiber melt homogenization system and method. Background Technology

[0002] In the textile industry, especially in the production of synthetic fibers, "solution homogenization and thickening" is a crucial process step closely related to solution spinning. Solution spinning involves dissolving a polymer in a suitable solvent to form a solution, then extruding it through spinning orifices and solidifying it into fibers in a coagulation bath. Solution homogenization and thickening typically refers to dissolving the polymer in a solvent and controlling the process through specific techniques to achieve higher molecular weights and viscosities, thereby improving the fiber's strength, modulus, and other properties.

[0003] Existing methods for homogenizing textile fiber melts mainly fall into the following three categories:

[0004] 1. Solid-phase thickening method: The polymer is heat-treated in solid form, usually near the melting point of the polymer, to increase the molecular weight without involving the melting process.

[0005] 2. Melt thickening: Heat treatment of polymers in the molten state to promote further reactions of molecular chains, such as chain elongation or cross-linking.

[0006] 3. Homogenization treatment: Mechanical stirring, pressurization and other methods are used to ensure that the polymer melt has consistent properties throughout the container, including temperature, viscosity and composition.

[0007] Regarding the homogenization and thickening of environmentally friendly waste fiber melt, due to its composition being different from that of traditional textile fiber melt, the environmentally friendly waste fiber melt contains small molecule byproducts when it is thermally melted. These small molecule byproducts need to be removed during the homogenization process. However, even without homogenization and thickening, the viscosity of the environmentally friendly waste fiber melt is very high, and traditional filtration methods cannot remove these small molecule byproducts at all. The only solution is to form the melt into a film and then remove these small molecule byproducts by heating and volatilizing, thereby increasing the uniformity and viscosity of the melt.

[0008] Chinese Patent Application No. 201510119535.5 discloses an apparatus for homogenizing a plastic material melt (K), which has a homogenizing element (41) having multiple flow channels (S1 to Sn) that are different in at least one feature selected from the group consisting of length (L1 to Ln), cross-sectional area, and cross-sectional shape. When flowing through the homogenizing element (41), the plastic material melt (K) is divided into multiple streams (T1 to Tn) flowing through the respective flow channels (S1 to Sn). Upon exiting their respective flow channels (S1 to Sn), the streams (T1 to Tn) have different flow velocities (v1 to vn), thus causing the plastic material melt (K) to expand and shear as it transitions to a uniform flow. As a result, the homogenization of the plastic material melt (K) occurs in a simple, efficient, and effective manner.

[0009] However, the homogenization device described above is not suitable for homogenizing waste fiber melt and cannot achieve the purpose of removing small molecule byproducts.

[0010] Furthermore, Chinese patent application number 201310241495.2 discloses a melt polycondensation reaction method for preparing high-viscosity melts. Molten monomer blends or prepolymers slide down the outer wall of tubular falling film elements to undergo polycondensation. The melt on each falling film element converges at the bottom of the polycondensation reactor for further stirring and homogenization. The material is then discharged after the reaction is complete. The polycondensation reactor implementing this method includes a vertical shell, an upper end cap, a lower bottom shell, falling film elements, a heat transfer system, a film distributor, and a ribbon agitator. The upper section of the falling film element is a corrugated tube or bellows, and the lower section is a circular tube to accommodate the increase in melt viscosity during the reaction.

[0011] Although the above-mentioned high-viscosity melt melt polycondensation reaction method also uses the technique of forming a film from the melt and then separating the small molecule by-products by heat exchange treatment, the heat exchange path of the melt film formation in the above-mentioned technical solution is short, and the melt is very easy to form dead corners, resulting in carbonization. Summary of the Invention

[0012] To address the above problems, this invention provides an environmentally friendly waste filament melt homogenization system and method. By setting up a piston module, the piston module scrapes and concentrates the film-forming environmentally friendly waste filament melt, transferring it to the side wall of the chamber for further film formation and flow. The heat in the insulation jacket is used for heat exchange, which extends the film-forming tube as a supplement. This allows the environmentally friendly waste filament melt to obtain the longest possible heat exchange path within the chamber, thereby separating small molecule byproducts. At the same time, it avoids the waste filament melt from not flowing in certain areas, preventing carbonization and improving the homogenization quality and viscosity of the environmentally friendly waste filament melt.

[0013] To achieve the above objectives, the present invention provides the following technical solution:

[0014] An environmentally friendly waste filament melt homogenization system includes:

[0015] Homogenizer cylinder assembly, film-forming tube assembly, piston module and power module;

[0016] The homogenizer cylinder assembly is vertically arranged, and a sealed chamber is provided inside the homogenizer cylinder assembly. An insulation chamber is provided on the outside of the chamber. The chamber is connected to an external vacuum pumping device through a vacuum pumping connector.

[0017] The film-forming tube assembly is vertically arranged in the chamber. The film-forming tube assembly includes a film-forming tube and a heat exchange tube. The film-forming tube is coaxially sleeved on the outside of the heat exchange tube. The top of the film-forming tube is open and the bottom of the film-forming tube is sealed. Environmentally friendly waste filament solution flows on the outer wall of the film-forming tube. Both ends of the heat exchange tube are open. A heat exchange channel is formed between the film-forming tube and the heat exchange tube. The heat exchange channel flows with the heat exchange medium.

[0018] The piston module is sleeved on the outside of the film-forming tube. The piston module reciprocates along the film-forming tube. When the piston module moves upward along the film-forming tube, it scrapes off the environmentally friendly waste filament solution flowing on the outer surface of the film-forming tube. When the piston module moves to the top of the film-forming tube, the outer periphery of the piston module opens a liquid outlet slit, and the environmentally friendly waste filament solution flows onto the side wall of the chamber. The piston module includes a piston plate and a scraper block assembly. The piston plate moves along the film-forming tube, and the scraper block assembly is installed on the piston plate. The scraper block assembly is arranged in a one-to-one correspondence with the film-forming tube. When the scraper block assembly moves upward along the film-forming tube, it closes up and hugs the film-forming tube. When the scraper block assembly moves downward along the film-forming tube, it opens up and is spaced apart from the film-forming tube.

[0019] The power module is mounted on the homogenizer cylinder assembly, and the power module drives the piston module to move along the film-forming tube.

[0020] As an improvement, the homogenizer cylinder assembly includes an inner liner and an outer jacket;

[0021] The inner liner is sealed at both ends by an upper cover and a bottom shell to form the chamber. The bottom shell is provided with an outlet for environmentally friendly waste wire melt.

[0022] The outer jacket surrounds the inner liner, and the outer jacket contains the heat-insulating cavity. The outer jacket also has an input pipe and an output pipe for the heat-insulating medium.

[0023] As an improvement, a spiral flow channel for the flow of insulation medium is formed inside the insulation cavity by spirally arranged baffles.

[0024] As an improvement, the top of the chamber is provided with a fixing plate for installing the heat exchange tube, and the top heat exchange medium inlet of the heat exchange tube is provided on the fixing plate. The fixing plate divides the top of the chamber into a liquid distribution chamber for the heat exchange medium, and the top of the homogenizer cylinder is provided with an input connection nozzle for inputting the heat exchange medium, which communicates with the liquid distribution chamber.

[0025] As an improvement, a spacer plate for fixing the film-forming tube is arranged parallel to the bottom of the fixed plate, and the heat exchange medium outlet at the top of the film-forming tube is located on the spacer plate. A heat exchange medium output cavity is formed between the spacer plate and the fixed plate, and an output connection nozzle for outputting the heat exchange medium is provided on the homogenizer cylinder assembly and communicates with the output cavity.

[0026] As an improvement, a liquid distribution plate is sleeved on the top of the film-forming tube. The liquid distribution plate is fixedly connected to the side wall of the chamber. The liquid distribution plate is evenly distributed with a plurality of liquid distribution holes that correspond one-to-one with the film-forming tube, and the liquid distribution holes are connected to each other by grooves.

[0027] The homogenizer cylinder assembly is equipped with an inlet head for inputting environmentally friendly waste wire melt, and the outlet of the inlet head is located above the separator plate.

[0028] As an improvement, the scraper block assembly includes symmetrical scraper blocks, which are arranged in a semi-circular arc shape, and a guide block and the guide rod are provided on the lower part of the scraper block.

[0029] As an improvement, the piston module further includes a tensioning module for driving the scraper block assembly to retract or expand, the tensioning module including gears, gear rings and sealing plates;

[0030] The gear is rotatably mounted on the piston plate. The gear is sleeved one-to-one with the film-forming tube, and the gears located on the same radius on the piston plate cooperate with each other. The gear has an arc-shaped groove, which is interlocked with the guide rod.

[0031] The gear ring is coaxially rotatably sleeved on the piston plate. The gear ring is located at the outer periphery of the piston plate and engages with the gear located at the outer periphery of the piston plate. A protruding guide post is provided on the outer circumference of the gear ring, and a guide groove corresponding to the guide post is provided on the side wall of the chamber.

[0032] The sealing plate is disposed above the gear and the gear ring. The sealing plate is provided with a sliding groove that corresponds to and cooperates with the guide block, and the sealing plate is fixedly connected to the piston plate.

[0033] As an improvement, a retaining edge is provided at the outer periphery of the sealing plate. The retaining edge is provided with the protrusion of the sealing plate, and a plurality of support columns are installed on the lower end face of the retaining edge. The support columns are inserted into the sealing plate.

[0034] A plurality of glass ball screws are provided along the outer periphery of the gear ring. When the gear ring rotates to mate with the support column, the glass ball screws lift up the baffle to form the liquid outlet slit.

[0035] In addition, this application also provides a homogenization method based on the environmentally friendly waste filament melt homogenization system described above. When the power module drives the piston module to move upward along the film-forming tube, the scraper block group on the piston module closes and hugs the film-forming tube, scraping off the environmentally friendly waste filament melt flowing in the film-forming tube. When the piston module moves to the top of the film-forming tube, the liquid outlet slit opens along the outer periphery of the piston module, and the environmentally friendly waste filament melt scraped off by the scraper block group flows to the side wall of the chamber through the liquid outlet slit.

[0036] At this time, the scraper block group opens, and then the power module drives the piston module to move down along the film-forming tube to the bottom. After that, the scraper block group closes again and hugs the film-forming tube. After the liquid outlet slit is closed, the scraping work of the environmentally friendly waste filament melt is repeated.

[0037] The beneficial effects of this invention are as follows:

[0038] (1) By setting up a piston module, the present invention scrapes and concentrates the environmentally friendly waste filament melt that forms a film, and transfers it to the side wall of the chamber for film formation and flow again. The heat in the insulation jacket is used for heat exchange, which is used to supplement and extend the film forming tube. This allows the environmentally friendly waste filament melt to obtain the longest possible heat exchange treatment in the chamber, thereby separating small molecule by-products. At the same time, it avoids the waste filament melt from not flowing in a certain part, avoids carbonization, and improves the homogenization quality and viscosity of the environmentally friendly waste filament melt.

[0039] (2) When the present invention scrapes and concentrates the environmentally friendly waste filament melt on the film-forming tube by using the scraper block group, the environmentally friendly waste filament melt is concentrated on the upper end face of the piston module. By moving the piston module along the film-forming tube, the environmentally friendly waste filament melt at the bottom of the film-forming tube is brought back to the bottom of the film-forming tube. This allows the environmentally friendly waste filament melt to be decomposed into small molecule byproducts through the side wall of the chamber, thereby improving the uniformity of the environmentally friendly waste filament melt. In addition, the piston module is automatically tensioned throughout the entire movement process, and the action is closely connected.

[0040] (3) When the piston module of the present invention is lifted to the top of the film forming tube, the liquid outlet slit is opened by the lifting of the baffle, so that the environmentally friendly waste wire melt located on the piston module can flow smoothly to the side wall of the chamber and form a film. When the piston module moves to the bottom of the film forming tube, the baffle descends again to form a blockage on the periphery of the piston module, close the liquid outlet slit, and prevent the environmentally friendly waste wire melt from flowing out.

[0041] (4) By utilizing the movement of the piston module, the present invention drives the tensioning of the scraper block group and the lifting of the baffle. The structure is precise, the action is closely connected and orderly, which increases the homogenization time of the environmentally friendly waste wire melt, resulting in high heat utilization rate, high decomposition rate, energy saving and environmental protection.

[0042] In summary, this invention has advantages such as good homogenization performance, good melt uniformity, low impurity content, and thorough pyrolysis separation of small molecule by-products, and is especially suitable for the field of environmentally friendly fiber melt technology for processing waste textiles and waste textile fibers.

[0064] Example 1:

[0065] like Figures 1 to 16 As shown, an environmentally friendly waste filament melt homogenization system includes:

[0066] Homogenizer cylinder assembly 1, film-forming tube assembly 2, piston module 3, and power module 4;

[0067] The homogenizer cylinder assembly 1 is vertically arranged, and a sealed chamber 10 is provided inside the homogenizer cylinder assembly 1. An insulation chamber 11 is provided on the outside of the chamber 10. The chamber 10 is connected to an external vacuuming device through a vacuuming connector 111.

[0068] The film-forming tube assembly 2 is vertically arranged in the chamber 10. The film-forming tube assembly 2 includes a film-forming tube 21 and a heat exchange tube 22. The film-forming tube 21 is coaxially sleeved on the outside of the heat exchange tube 22. The top of the film-forming tube 21 is open and the bottom of the film-forming tube 21 is sealed. Environmentally friendly waste filament solution flows on the outer wall of the film-forming tube 21. Both ends of the heat exchange tube 22 are open. A heat exchange channel 23 is formed between the film-forming tube 21 and the heat exchange tube 22. The heat exchange channel 23 flows with heat exchange medium.

[0069] The piston module 3 is sleeved on the outside of the film-forming tube 21. The piston module 3 reciprocates along the film-forming tube 21. When the piston module 3 moves upward along the film-forming tube 21, it scrapes off the environmentally friendly waste filament solution flowing on the outer surface of the film-forming tube 21. When the piston module 3 moves to the top of the film-forming tube 21, the outer periphery of the piston module 3 opens the liquid outlet slit 30, and the environmentally friendly waste filament solution flows onto the side wall of the chamber 10. The piston module 3 includes a piston plate. 31 and scraper block assembly 32, the piston plate 31 moves along the film-forming tube 21, the scraper block assembly 32 is installed on the piston plate 31, the scraper block assembly 32 is arranged in a one-to-one correspondence with the film-forming tube 21 and surrounds it, when the scraper block assembly 32 moves upward along the film-forming tube 21, the scraper block assembly 32 closes and hugs the film-forming tube 21, when the scraper block assembly 32 moves downward along the film-forming tube 21, the scraper block assembly 32 opens and is spaced apart from the film-forming tube 21;

[0070] The power module 4 is installed on the homogenizer cylinder 1. The power module 4 drives the piston module 3 to move along the film-forming tube 21. Specifically, the power module 4 includes a servo motor 41, a main shaft 42, a lead screw nut 43, a guide rod, and a guide sleeve. The servo motor 41 is installed on the top of the homogenizer cylinder 1. The main shaft 42 is rotated and installed in the chamber 10 by the servo motor 41. The lead screw nut 43 is installed on the piston module 3. The lead screw nut 43 and the main shaft 42 are connected by a thread. The guide rod is arranged parallel to the film-forming tube 21 and passes through the piston module 3 to limit the circumferential movement of the piston module 3. The guide sleeve is installed on the piston module and is used to cooperate with the guide rod. In addition, a propeller blade 421 is provided at the bottom of the main shaft 42. The propeller blade 421 rotates to agitate and discharge the gasified small molecule by-products.

[0071] The homogenizer cylinder assembly 1 includes an inner liner 12 and an outer jacket 13;

[0072] The two ends of the inner liner 12 are sealed by the upper cover 14 and the bottom shell 15 respectively to form the chamber 10. The bottom shell 15 is provided with an outlet 151 for environmentally friendly waste wire melt.

[0073] The outer jacket 13 surrounds the inner liner 12, and the heat insulation cavity 11 is provided inside the outer jacket 13. The outer jacket 13 is also provided with an input pipe 18 and an output pipe 19 for the heat insulation medium.

[0074] Furthermore, a spiral flow channel 17 for the flow of insulation medium is formed inside the insulation cavity 11 by a spirally arranged baffle 16.

[0075] It should be noted that the chamber 10 is used for the pyrolysis separation of small molecule by-products and the homogenization treatment of environmentally friendly waste filament melt. The environmentally friendly waste filament melt flows along the film-forming tube 21 and forms a melt film on the film-forming tube 21. A heat exchange medium flows inside the film-forming tube 21. Through the heat transfer of the heat exchange medium, the small molecule by-products in the film-shaped waste filament melt are pyrolyzed into gas as much as possible and separated from the waste filament melt, thereby improving the purity of the waste filament melt.

[0076] Furthermore, during the homogenization process of the environmentally friendly waste wire melt, an insulation jacket (i.e., outer jacket 13) is installed outside the chamber 10. An insulation medium flows inside the outer jacket 13 to insulate the chamber 10 and prevent uneven heating of the chamber 10.

[0077] Furthermore, it should be emphasized that the difference between this invention and the prior art lies in the fact that this invention provides a piston module 3 on the film-forming tube 21. The piston module 3 moves along the film-forming tube 21 within the chamber 10. A certain gap is left between the piston module 3 and the side wall of the chamber 10. When the piston module 3 moves upward along the film-forming tube 21, the scraper block assembly 32 closes and hugs the film-forming tube 21, forming a scraper ring around the film-forming tube 21. The scraper block assembly 32 scrapes the molten film from the film-forming tube 21, and the environmentally friendly waste filament melt is scraped off and flows onto the upper surface of the piston module 3 for temporary storage, until the piston module 3 moves. When the film-forming tube 21 reaches the top, a liquid outlet slit 30 is opened at the outer periphery of the piston module 3. The environmentally friendly waste wire melt is discharged outward through the liquid outlet slit 30. The environmentally friendly waste wire melt is guided to the side wall of the chamber 10. The environmentally friendly waste wire melt flows along the side wall of the chamber 10 to form a melt film. During the process of flowing along the side wall of the chamber 10, the heat-insulating medium flowing in the outer jacket 13 just transfers heat to the melt film on the chamber 10, and performs pyrolysis treatment on the small molecule by-products in the melt film, so that the small molecule by-products are converted into gas and escape. The escaped gas is discharged outward through the vacuum joint 111.

[0078] As the scraper block assembly 32 moves downward along the film-forming tube 21, the scraper block assembly 32 opens again, breaking away from the film-forming tube 21, allowing the environmentally friendly waste filament melt to flow again on the film-forming tube 21, and forming a melt film again on the film-forming tube 21.

[0079] Specifically, a fixing plate 101 for installing the heat exchange tube 22 is provided at the top of the chamber 10. The heat exchange medium inlet at the top of the heat exchange tube 22 is provided on the fixing plate 101. The fixing plate 101 divides the top of the chamber 10 into a liquid distribution chamber 102 for the heat exchange medium. The top of the homogenizer cylinder assembly 1 is provided with an input connector 103 for inputting the heat exchange medium, which communicates with the liquid distribution chamber 102. The input connector 103 inputs the heat exchange medium into the liquid distribution chamber 102. The heat exchange medium is dispersed by the fixing plate 101 and enters the corresponding heat exchange tube 22. The heat exchange medium flows along the heat exchange tube 22 and enters the bottom of the heat exchange tube 22.

[0080] Furthermore, a spacer plate 104 for fixing the film-forming tube 21 is arranged parallel below the fixing plate 101. The heat exchange medium outlet at the top of the film-forming tube 21 is located on the spacer plate 104. A heat exchange medium output chamber 105 is formed between the spacer plate 104 and the fixing plate 101. An output connector 106 for outputting the heat exchange medium is provided on the homogenizer cylinder 1 and communicates with the output chamber 105. The film-forming tube 21 is sleeved on the outside of the heat exchange tube 22. The heat exchange medium entering the bottom of the heat exchange tube 22 enters the space between the heat exchange tube 22 and the film-forming tube 21 through the bottom opening of the heat exchange tube 22. The pressure of the subsequent heat exchange medium causes the heat exchange medium to enter the output chamber 105. The heat exchange medium is output through the output connector 106 to realize the circulation of the heat exchange medium.

[0081] To facilitate the uniform distribution of environmentally friendly waste filament melt in the film-forming tube 21, a liquid distribution plate 107 is sleeved on the top of the film-forming tube 21. The liquid distribution plate 107 is fixedly connected to the side wall of the chamber 10. The liquid distribution plate 107 is evenly distributed with a plurality of liquid distribution holes 108 that correspond one-to-one with the film-forming tube 21, and the liquid distribution holes 108 are connected to each other through grooves 109.

[0082] The homogenizer cylinder assembly 1 is equipped with an inlet head 110 for inputting environmentally friendly waste wire melt, and the outlet of the inlet head 110 is located above the liquid separator plate 107.

[0083] After the hot-melted environmentally friendly waste filament melt is input through the liquid inlet head 110, it is dispersed by the liquid distribution plate 107. The dispersed environmentally friendly waste filament melt flows along the outer arm of the film forming tube 21 through the liquid distribution hole 108 to form a melt film. Finally, the environmentally friendly waste filament melt after homogenization is discharged out through the outlet 151 to enter the next process.

[0084] In a preferred embodiment, the scraper block group 32 includes symmetrical scraper blocks 321, which are arranged in a semi-circular arc shape, and a guide block 322 and the guide rod 323 are provided on the lower part of the scraper block 321.

[0085] Furthermore, the piston module 3 also includes a tensioning module 33 for driving the scraper block assembly 32 to retract or expand, the tensioning module 33 including a gear 331, a gear ring 332 and a sealing plate 333;

[0086] The gear 331 is rotatably mounted on the piston plate 31. The gear 331 is sleeved one-to-one with the film-forming tube 21. The gears 331 located on the piston plate 31 at the same radius cooperate with each other. The gear 331 has an arc-shaped groove 3311, which is interlocked with the guide rod 323.

[0087] The gear ring 332 is coaxially rotatably sleeved on the piston plate 31. The gear ring 332 is located at the outer periphery of the piston plate 31, and the gear ring 332 cooperates with the gear 331 located at the outer periphery of the piston plate 31. A protruding guide post 3321 is provided on the outer circumference of the gear ring 332, and a guide groove 100 corresponding to the guide post 3321 is provided on the side wall of the chamber 10.

[0088] The sealing plate 333 is disposed above the gear 331 and the gear ring 332. The sealing plate 333 is provided with a sliding groove 3331 that corresponds to and cooperates with the guide block 322, and the sealing plate 333 is fixedly connected to the piston plate 31.

[0089] It should be noted that the opening and closing of the scraper block 321 is controlled by the gear 331 and the gear ring 332. When the piston module 3 is at the bottom of the film-forming tube 21, the guide post 3321 is at the bottom of the guide groove 100. When the piston module 3 moves upward along the film-forming tube 21, the gear ring 332 will rotate due to the cooperation between the inclined guide groove 100 and the guide post 3321. After the gear ring 332 rotates, it will drive the gear 331 to rotate. When the gear 331 rotates, the arc groove 3311 will drive the guide rod 323 to gradually move closer through the cooperation between the arc groove 3311 and the guide rod 323. Through the guiding cooperation between the guide block 322 and the slide groove 3331, the scraper block 321 will gradually move closer in a directional manner, thereby achieving the goal of the scraper block 321 gradually closing and hugging the film-forming tube 21.

[0090] To further explain, in reverse operation, when the scraper block 321 that grips the film-forming tube 21 reaches the top of the film-forming tube 21, the guide post 3321 is located at the top of the guide groove 100. When the piston module 3 moves downward along the film-forming tube 21, the cooperation between the inclined guide groove 100 and the guide post 3321 will cause the gear ring 332 to rotate in the opposite direction, the gear ring 332 to reset, and the scraper block 321 to disperse and open.

[0091] It is worth emphasizing that when the scraper block 321 moves downward, during the time it moves from the top to the bottom of the film-forming tube 21, the environmentally friendly waste filament melt forms a melt film on the outer wall of the film-forming tube 21 again.

[0092] When the guide post 3321 moves within the guide groove 100, especially when it moves along the inclined guide groove 100 at two extreme positions, a one-way structure is provided at both extreme positions to prevent the guide post 3321 from retracting and being unable to move along the inclined guide groove 100. Specifically, the one-way structure is a ratchet structure, that is, the guide post 3321 can pass through the rotating ratchet, but when retracting, the guide post 3321 cannot pass through the ratchet, so that the guide post 3321 can only move along the inclined guide groove 100, thereby realizing the rotation of the gear ring 332.

[0093] In addition, in order to ensure the concentration of the scraped environmentally friendly waste wire melt, a retaining edge 334 is provided at the outer periphery of the piston module 3, that is, a retaining edge 334 is provided at the outer periphery of the sealing plate 333. The retaining edge 334 is provided with the protrusion of the sealing plate 333, and a plurality of support columns 3341 are installed on the lower end face of the retaining edge 334. The support columns 3341 are inserted into the sealing plate 333.

[0094] A plurality of glass ball screws 3322 are provided along the outer periphery of the gear ring 332. When the glass ball screws 3322 rotate with the gear ring 332 to correspond to the support column 3341, they lift up the baffle 334 to form the liquid outlet slit 30.

[0095] Specifically, when the piston module 3 moves to the top of the film-forming tube 21, the gear ring 332 rotates, causing the scraper block 321 to separate. Through the cooperation of the glass ball screw 3322 and the support column 3341, the lightweight baffle 334 is lifted up, thereby forming a set of liquid outlet slits 30 between the baffle 334 and the sealing plate 333. When the piston module 3 moves upward along the film-forming tube 21, the glass ball screw 3322 and the support column 3341 are misaligned, and the baffle 334 descends again, forming an obstacle to block the waste wire melt at the outer circumference of the sealing plate 333.

[0096] Example 2:

[0097] Referring to Example 1, the difference between Example 2 and Example 1 lies in the following:

[0098] like Figure 17 As shown, a homogenization method based on the environmentally friendly waste filament melt homogenization system described in Example 1 includes the following steps:

[0099] Step 1: Heating and heat preservation treatment. Heat exchange medium is circulated in heat exchange channel 23 to heat up chamber 10. Simultaneously, heat preservation medium is circulated in heat preservation chamber 11. After chamber 10 is heated to the preset working temperature, the next working step is started.

[0100] Step 2: Waste filament melt film formation. Environmentally friendly waste filament melt flows on the outer wall of the film forming tube 21. The environmentally friendly waste filament melt forms a melt film on the film forming tube 21. The melt film is heated by heat transfer through the heat exchange channel 23, causing small molecule byproducts to vaporize and escape.

[0101] Step 3, scraping process: When the waste filament melt flows to the bottom of the film-forming tube 21, the power module 4 drives the piston module 3 to move upward along the film-forming tube 21. During the movement, the gear ring 332 rotates, and with the transmission of the gear 331, it drives the scraper block 321 to close and hold the film-forming tube 21 tightly. Then, as the piston module 3 moves upward, the scraper block 321 scrapes and concentrates the melt on the film-forming tube 21, so that the melt for film formation flows onto the piston module 3.

[0102] Step 4: Film Formation Again. When the piston module 3 moves to the top of the film forming tube 21, the toothed ring 332 reverses and resets, causing the scraper block 321 to loosen, while the baffle 334 lifts up, opening the liquid outlet slit 30, allowing the waste wire melt on the piston module 3 to flow through the liquid outlet slit 30 onto the side wall of the chamber 10. The waste wire melt flows along the side wall of the chamber 10 and gradually forms a film. Relying on the heating of the heat preservation medium in the heat preservation chamber 11, the small molecule by-products inside the waste wire melt are heated and escape.

[0103] Then, the power module 4 drives the piston module 3 to descend to the bottom of the film-forming tube 21. Then, steps three and four are repeated to cycle through the scraping and film-forming work of the environmentally friendly waste filament melt. Compared with traditional and existing homogenizers, the waste filament melt of the present invention has a longer film-forming path, a longer film-forming time, and more complete thermal decomposition of small molecule by-products.

[0104] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
