Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of blended fabric recycling devices, and particularly relates to a polyester blended fabric recycling system. BACKGROUND

[0002] Polyester blended fabric is a kind of fabric that combines polyester (also known as polyester fiber) with other fibers (such as cotton, spandex, nylon, wool, silk, hemp, etc.). This fabric not only has excellent mechanical properties of polyester fiber fabric, but also retains the excellent performance of other fiber fabrics. It is widely used in clothing, home, sports equipment and other fields, such as clothing, home goods and sports equipment.

[0003] According to the type and proportion of blended fibers, various fabrics with different properties can be made, such as polyester cotton blend, polyester spandex blend and polyester wool blend. Among them, polyester cotton blend combines the comfort of cotton with the excellent mechanical properties of polyester, and is often used to make T-shirts, coats, etc.; polyester spandex blend combines the wear resistance of polyester with the elasticity of spandex, and is suitable for making outdoor clothing and home goods; and polyester wool blend combines the mechanical properties of polyester with the warmth of wool, and is often used to make sweaters, overcoats, etc.

[0004] The above finished products will be discarded after use, and the recycling of polyester blended fabric is a complex but important process, which involves the reuse of waste textiles and helps to reduce environmental pollution and save resources. At present, the recycling of polyester blended fabric mainly adopts physical recycling, chemical recycling and energy recycling methods.

[0005] Among them, the physical recycling method mainly includes:

[0006] Extrusion granulation: This is a common physical recycling method, which melts and extrudes the fibers into granules by using an extruder after crushing, cleaning and drying the waste textiles, and then uses them to produce new textiles. However, due to the large difference in physical properties between polyester and other fibers, direct extrusion granulation may not be able to effectively separate and reuse each component.

[0007] Mechanical separation: In some cases, mechanical means (such as screening, air separation, etc.) can be used to preliminarily separate polyester from other fibers. However, this method is usually suitable for blended fabrics with high polyester content and obvious differences from other fibers.

[0008] The chemical recycling method mainly includes:

[0009] Hydrolysis method: Using water or other solvents to decompose polyester fiber materials into small molecular compounds under high temperature and high pressure, and then recycling useful substances through separation and purification processes. This method can effectively recycle polyester, but the processing process is complex and the cost is high.

[0010] Alcoholysis: In this method, polyester materials are degraded into low molecular weight alcoholysis products using alcohol compounds as solvents and with the help of catalysts. This method has the advantages of mild reaction conditions and easy separation of products, making it one of the research hotspots in the field of polyester recycling.

[0011] Other chemical methods: such as alkaline hydrolysis, etc. These methods have their own advantages and disadvantages, and the specific choice depends on factors such as the type and composition of the waste textiles and the recycling goals.

[0012] Energy recovery methods mainly include:

[0013] Incineration: Waste textiles are incinerated as fuel to recover heat energy. Although this method is simple and fast, it causes secondary pollution and waste of resources, so it is usually not the preferred recycling method.

[0014] In summary, although there are multiple ways to recycle polyester blended fabrics, the recycling devices used in each scheme differ in function. If multiple schemes need to be combined and operated, multiple devices need to be used, which not only occupies space but also increases the debugging cost between devices and has strict operation requirements for operators.

Detailed Implementation

[0048] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. The described embodiments are merely some, not all, of the embodiments of the present invention. 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.

[0049] like Figures 1-5 As shown, a recycling system for polyester blended fabric includes a vessel 1 with a reaction chamber 101. The upper part of the vessel 1 is provided with a reactant interface 6 and a positive and negative pressure interface 7, and the lower part of the vessel 1 is provided with a sewage discharge interface 8.

[0050] A filter cylinder 2 is provided inside the reaction chamber 101, and a guide spiral blade 3 is provided on the inner wall of the filter cylinder 2; the two ends of the filter cylinder 2 are movably connected to the two sides of the vessel body 1.

[0051] A spiral feed assembly 4 is provided on one side of the vessel body 1 for conveying materials into the filter cartridge 2 or for discharging materials from the filter cartridge 2.

[0052] A filter cartridge rotation drive assembly 5 is provided on the other side of the vessel body 1, which is used to drive the filter cartridge 1 to rotate clockwise or counterclockwise in the reaction chamber 101.

[0053] In practical applications, this system also includes a base 9, which supports both ends of the vessel body via a pair of brackets 10. Furthermore, a protective cover 11 is provided for the transmission components of the system.

[0054] Multiple sewage discharge ports 8 can be set as needed and connected to an external collection device through pipelines, enabling the recovery of different reactants involved in the reaction.

[0055] Working principle:

[0056] Feeding operation

[0057] The filter cartridge rotation drive assembly 5 operates, driving the filter cartridge 2 to rotate clockwise. Simultaneously, the positive and negative pressure ports 7 extract air from the reaction chamber via an external air extraction device, thereby creating a negative pressure within the reaction chamber 101. The material to be recycled enters the filter cartridge 2 under the drive of the screw feed assembly 4, and is filled to the other end of the filter cartridge 2 by the action of the guide screw blades 3. After feeding is completed, feeding is stopped, and a specified reactant is introduced into the reaction chamber 101 through the reactant port 6 to achieve chemical separation of polyester from other fiber components in the blended fabric. After separation is completed, the reactant liquid containing polyester depolymerization components is discharged by opening the drain port 8. At this point, only the fiber components other than polyester (such as spandex, cotton, wool, etc.) of the separated blended fabric remain in the filter cartridge 2.

[0058] Discharge operation

[0059] The filter cartridge rotation drive assembly 5 operates, driving the filter cartridge 2 to rotate counterclockwise. Simultaneously, the positive and negative pressure interfaces 7 input air into the reaction chamber through an external air extraction device, thereby creating positive pressure within the reaction chamber 101. The fiber components other than polyester in the separated blended fabric enter the screw feed assembly 4 under the drive of the guide spiral blades 3, and are further discharged outwards under the further drive of the screw feed assembly 4, thus effectively recovering the fiber components other than polyester from the separated blended fabric.

[0060] To ensure the intelligent operation of this system, this embodiment also provides a monitoring module interface 12 on the vessel body 1 for real-time monitoring of the environmental status inside the vessel body. The monitoring module 13 can be a common temperature and pressure sensor, liquid level gauge, etc.

[0061] As a further optimization of this embodiment, a window 207 and a corresponding window plate can be provided on the outer wall of the filter cartridge 2. This structure enables thorough inspection or cleaning of the filter cartridge in the future.

[0062] like Figures 5-7 , Figure 9 and Figure 10 As shown, in this embodiment, the filter cartridge 2 includes a filter cartridge body 201, and filter cartridge end caps 202 and filter cartridge retaining rings 203 disposed at both ends. The filter cartridge end caps 202 are connected to the filter cartridge rotation drive assembly 5. An inlet / outlet extension pipe 204 is disposed on the outer side of the filter cartridge retaining ring 203. The inlet / outlet extension pipe 204 passes through the reactor body 1 and is connected to the spiral inlet / outlet assembly 4.

[0063] It should be noted that in this embodiment, an extension tube flange seat 205 is provided between the inlet / outlet extension tube 204 and the vessel body 1, and an extension tube bearing 206 is provided to sleeve the inlet / outlet extension tube 204 and allow it to rotate freely relative to the extension tube flange seat 205.

[0064] In this structure, the filter cartridge 2 can be driven to rotate freely relative to the vessel body 1 by the filter cartridge rotation drive component 5. In specific applications, this can promote the full stirring and mixing of the material in the filter cartridge 2 with the reactant and water in the reaction chamber 101, thereby achieving material separation by combining physical stirring and chemical reaction.

[0065] like Figure 5 and Figure 7 As shown, the spiral feeding and discharging assembly 4 in this embodiment includes a feeding and discharging pipe 401. The feeding and discharging pipe 401 has a left feeding and discharging pipe connection port 402 and a right feeding and discharging pipe connection port 403 that are symmetrically arranged on the pipe wall. The left feeding and discharging pipe connection port 402 is connected to the feeding and discharging pipe extension pipe 204, and the right feeding and discharging pipe connection port 403 is connected to a rotary motor 404. The rotating shaft of the rotary motor 404 is connected to a shaftless spiral blade 405 that can pass through the feeding and discharging pipe 401 and the feeding and discharging pipe extension pipe 204 and extend into the inner cavity of the filter cartridge 2.

[0066] The upper port of the inlet / outlet pipe 401 serves as the material inlet 406, and the lower port of the inlet / outlet pipe 401 serves as the material outlet 407.

[0067] Specifically, this structure allows the inlet / outlet extension pipe 204 and the inlet / outlet pipe 401 to form a interconnected channel for material passage. Under the action of the rotary motor 404 (at this time, the negative pressure of the positive and negative pressure interfaces works, forming a suction force), the shaftless spiral blades 405 continuously feed the material entering from the material inlet 406 into the inlet / outlet extension pipe 204. After the material enters the filter cartridge 2 through the inlet / outlet extension pipe 204, it is then guided by the guide spiral blades 3 to fill the left end of the filter cartridge 2. This method allows a large amount of material to be fed into the filter cartridge 2.

[0068] After the separation operation is completed, the filter cartridge 2 and the shaftless spiral blade 405 rotate in opposite directions. Driven by the guide spiral blade 3 (at this time, the positive pressure of the positive and negative pressure interface is working to form a blowing force), the material in the filter cartridge 2 is squeezed into the inlet and outlet extension pipe 204, and under the action of the shaftless spiral blade 405, the material is conveyed to the material outlet 407. The material is discharged through the material outlet 407. A collection box can also be set at this point for the recovery of the discharged material.

[0069] To facilitate material feeding and discharging, in this embodiment, the feed pipe 401 is arranged vertically, the material inlet 406 is located at the top, and the material outlet 407 is located at the bottom. During discharge, the material can fall freely along the material outlet 407 under the action of gravity.

[0070] In order to ensure the smooth operation, the material outlet 407 needs to be blocked when feeding, and the material inlet 406 needs to be blocked when discharging. The blocking material can be a pipe plug 408.

[0071] It should be noted that since the inlet / outlet extension pipe 204 rotates together with the filter cartridge 2 during operation, if the inlet / outlet pipe 401 is directly fixed to the inlet / outlet extension pipe 204, the inlet / outlet extension pipe 204 will also rotate, making it impossible to complete the feeding and discharging operations. Therefore, in this embodiment, the inlet / outlet pipe connecting seat 409 provides a contactless connection between the outer ports of the inlet / outlet pipe 401 and the inlet / outlet extension pipe 204, ensuring that the rotation of the inlet / outlet extension pipe 204 does not affect the inlet / outlet pipe 401.

[0072] like Figure 5 and Figure 6As shown, the filter cartridge rotation drive assembly 5 includes a filter cartridge rotation motor 502 with a first transmission sprocket 501 sleeved on a rotating shaft, and a filter cartridge rotating tube 503 that can penetrate the vessel body 1. One end of the filter cartridge rotating tube 503 is fixedly connected to the filter cartridge end cover 202, and a second transmission sprocket 504 is provided on the outer wall of the other end. The first transmission sprocket 501 and the second transmission sprocket 504 are connected by a chain 505.

[0073] It should be noted that in this embodiment, a filter cartridge rotating tube flange seat 506 is provided between the filter cartridge rotating tube 503 and the vessel body 1, and a filter cartridge rotating tube bearing 507 is provided to sleeve the filter cartridge rotating tube 503 and allow it to rotate freely relative to the filter cartridge rotating tube flange seat 506.

[0074] By controlling the rotation direction of the filter cartridge rotary motor 502, the rotation of the filter cartridge rotating tube 503 is indirectly driven, which in turn ultimately drives the rotation of the filter cartridge 2 that is fixed to the filter cartridge rotating tube 503.

[0075] As a specific connection form between the filter cartridge tube 503 and the filter cartridge end cap 202 in this embodiment, a first sealing bushing 14 is provided at the axial position of the filter cartridge end cap 202 to partially sleeve the end of the filter cartridge tube 503, and a second sealing bushing 15 is provided on the outer wall of the filter cartridge end cap 202 to sleeve the outer wall of the filter cartridge tube 503. Through this structure, the filter cartridge tube 503 and the filter cartridge end cap 202 are tightly fixed together.

[0076] In view of the above structure, this embodiment also provides a mechanism for heating the filter cartridge, which is used to dry the material after the separation work is completed and after all the reactants in the reaction chamber have been discharged.

[0077] like Figure 5 , Figure 6 and Figure 11 As shown, a first annular baffle 16 is provided on the inner side of the filter cartridge end cap 202. The first annular baffle 16, the filter cartridge end cap 202, and the filter cartridge body 201 form a first annular heating chamber 18. A heating chamber baffle 19 is provided in the first annular heating chamber 18, dividing the first annular heating chamber 18 into a first liquid inlet heating chamber 20 and a second liquid inlet heating chamber 21 that are independent of each other. A second annular baffle 17 is provided on the inner side of the filter cartridge retaining ring 203. The second annular baffle 17, the filter cartridge retaining ring 203, and the filter cartridge body 201 form a second annular heating chamber 22.

[0078] The guide spiral blade 3 includes a plurality of spiral blades 302 with spiral grooves 301, and the spiral grooves 301 and the inner wall of the filter cylinder 2 form a spiral heating channel 23; one end of the spiral blade 302 is connected to the first annular heating cavity 18, and the other end of the spiral blade 302 is connected to the second annular heating cavity 22.

[0079] The outer wall of the first sealing bushing 14 is provided with a plurality of liquid inlet holes 24, and the liquid inlet holes 24 are connected to the first liquid inlet heating chamber 20 through a first liquid inlet channel 25 connected to the filter cartridge end cap 202; the outer wall of the first sealing bushing 14 is also provided with a plurality of second liquid inlet channels 26 connected to the filter cartridge end cap 202, one end of the second liquid inlet channel 26 is connected to the second liquid inlet heating chamber 21, and the filter cartridge end cap 202 is provided with a liquid outlet hole 27 that can connect the second liquid inlet channel 26 to the second sealing bushing 15;

[0080] The filter tube 503 is provided with a first filter tube outlet hole 28 that connects the second sealing bushing 15 and the inner cavity of the filter tube 503, and a second filter tube outlet hole 29 is provided at the outer end of the filter tube 503.

[0081] The filter cartridge tube 503 is embedded with an inlet tube 30. One end of the inlet tube 30 extends into the first sealing bushing 14, and the other end of the inlet tube 30 serves as an inlet 31.

[0082] Specifically, in this embodiment, a mechanism for heating the filter cartridge 2 is provided. The heat source can be heating oil, which is transported by an external heating oil circulation conveying device and forms a circulating heating channel on the inner wall of the filter cartridge 2 to achieve the drying treatment of the separated materials in the filter cartridge.

[0083] The working principle is as follows:

[0084] Heating oil enters the first sealing sleeve 14 through the inlet of the inner inlet pipe 30, enters the first inlet heating chamber 20 through the inlet hole 24 and the first inlet channel 25, and enters the second annular heating chamber 22 through part of the spiral heating channel 23. After the second annular heating chamber 22 is filled, the heating oil returns to the second inlet heating chamber 21 through the empty spiral heating channel 23, and enters the second sealing sleeve 15 through the outlet hole 27 under the drive of oil pressure. Then it enters the inner cavity of the filter cartridge 503 through the outlet hole 28 of the first filter cartridge tube, and finally returns to the external heating oil circulation conveying device along the outlet hole 29 of the second filter cartridge tube.

[0085] In this way, the filter cartridge is circulated and heated.

[0086] like Figure 5 and Figure 8 As shown, as an optimization of this system, a hot water jacket layer 32 is provided on the outer side of the vessel body 1, and a hot water inlet interface 33 and a hot water outlet interface 34 are provided on the hot water jacket layer 32. Specifically, by setting the hot water jacket layer 32, this embodiment can provide the required ambient temperature for operation, ensuring the full reaction of the reactant and the material.

[0087] In this embodiment, the hot water inlet 33 is located at the bottom of the hot water jacket layer 32, and the hot water outlet 34 is located at the top of the hot water jacket layer 32.

[0088] In this structure, the hot water inlet 33 and the hot water outlet 34 are respectively connected to an external hot water circulation supply device through water pipes. In the hot water jacket layer 32, hot water enters the hot water jacket layer 32 from the hot water inlet 33 and slowly raises the water level. When it reaches the top, it is discharged along the hot water outlet 34, so that the hot water can fill the entire hot water jacket layer 32, thereby providing a stable working thermal environment for the vessel body 1.

[0089] like Figure 5 and Figure 8 As shown, as a further optimization of this system, an insulation jacket layer 35 is also provided on the outside of the hot water jacket layer 32. The insulation jacket layer 35 can keep the temperature of the hot water in the hot water jacket layer 32 warm, minimize heat loss, and thus reduce the power consumption of this system.

[0090] The insulation jacket layer 35 is filled with insulation cotton. Insulation cotton is a new type of insulation material made from a variety of raw materials, which has high-efficiency heat insulation performance.

[0091] The above description is merely illustrative of the embodiments of the present invention and is not intended to limit the present invention. For those skilled in the art, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
