Description

Technical Field

[0001] This application relates to the field of waste treatment technology, and in particular to a waste treatment device for polyester-cotton fabric production. Background Technology

[0002] Fabric production waste disposal is an important aspect of environmental protection and resource recycling. Waste fabrics and yarns can be reprocessed, such as through spinning and weaving, to create new textile products. This method not only reduces the amount of waste but also saves raw materials and energy. For some high-quality waste fabrics, they can be transformed into products for other uses, such as home decorations and handicrafts, through cutting and sewing.

[0003] A search revealed that CN217678014U discloses a novel waste treatment device for knitting machines. By setting up a waste collection trough, the waste generated by the knitting machine can be collected. Furthermore, the cooperation of the suction trough, the first suction mechanism, and the second suction mechanism can effectively adsorb thread ends and waste scraps to the middle layer of the support platform for processing. An activated carbon filter screen is set at the water pump inlet to effectively prevent the inlet from being blocked by waste over time. By setting a brush on the push plate, the waste on the filter screen can be effectively cleaned while avoiding direct friction between the push plate surface and the filter screen.

[0004] Regarding the aforementioned technologies, the inventors believe that the following technical defects exist and require improvement:

[0005] This device only achieves centralized recycling of waste. For polyester-cotton blended fabrics, due to the significant differences in the chemical properties of cotton and polyester fibers, centralized recycling alone cannot effectively separate cotton and polyester fibers, thus reducing its practicality.

[0036] This application discloses a waste treatment device for polyester-cotton fabric production. (Refer to...) Figures 1 to 6The waste treatment equipment for polyester-cotton fabric production includes a reactor body 1, a feed hopper 2, a separation box 3, a straight connecting pipe 4, an alcoholysis liquid recovery frame 5, a heating component 6, and a cotton fiber washing component 7.

[0037] Heating component 6 is used to heat reactor body 1, feeding hopper 2 is used to add a certain amount of alcoholysis agent and catalyst, reactor body 1 is used to fully stir the waste and degrade polyester, separation box 3 is used to separate alcoholysis agent and cotton fiber, alcoholysis liquid recovery box 5 is used to centrally recover alcoholysis liquid, and cotton fiber cleaning component 7 is used to clean the separated cotton fiber and remove surface alcoholysis agent and catalyst.

[0038] The separation box 3 is also provided with an inclined filter plate 8, a DC motor 9, a drive shaft 10 and a material feeding plate 11 on one side. The inclined filter plate 8 is installed inside the separation box 3. The DC motor 9 is installed on the outside of the separation box 3 and is used to connect the drive shaft 10. The drive shaft 10 is set above the inclined filter plate 8 and is rotatably connected to the inner surface of the separation box 3. The material feeding plate 11 is fixedly connected to the outside of the drive shaft 10 and is used to feed cotton fibers.

[0039] The heating assembly 6 includes a heat-conducting shell 61, a sealing cover 62, and an electric heating tube 63. The electric heating tube 63 is arranged in a ring array inside the heat-conducting shell 61. The heat-conducting shell 61 is snapped onto the outside of the reactor body 1, and the sealing cover 62 is sleeved on the outside of the heat-conducting shell 61.

[0040] The cotton fiber washing assembly 7 includes a support frame 71, a fixing sleeve 72, a stepper motor 73, and a material swaying fan blade frame 74. The fixing sleeve 72 is installed on the top of the support frame 71, the stepper motor 73 is installed on the outside of the support frame 71, and one end of the material swaying fan blade frame 74 is fixedly connected to the motor shaft of the stepper motor 73 through a coupling.

[0041] A stepper motor 12, a corrosion-resistant shaft 13, and a stirring rod 14 are also provided on one side of the reactor body 1. The stepper motor 12 is installed at the top center of the reactor body 1 and is used to connect the corrosion-resistant shaft 13. The corrosion-resistant shaft 13 is rotatably connected inside the reactor body 1, and the stirring rod 14 is welded to the outer wall of the corrosion-resistant shaft 13.

[0042] A discharge pipe 15 is also tightly fitted at the connection between the reactor body 1 and the separation box 3.

[0043] A water pump 16 is also installed on the outside of the straight connection pipe 4.

[0044] There are three sets of drive shafts 10, and the height of the three sets of drive shafts 10 decreases sequentially inside the separation box 3.

[0045] The general process of using the waste treatment equipment for polyester-cotton fabric production in this embodiment of the application is as follows:

[0046] The alcoholysis agent and catalyst, along with the waste polyester-cotton blended fabric, are fed into the reactor body 1 from the feed hopper 2. Typically, the amount of alcoholysis agent used is several times the weight of the polyester-cotton blended fabric, while the amount of catalyst is relatively small. Then, the electric heating tube 63 is turned on, and the heat emitted by the electric heating tube 63 is transferred to the reactor body 1 through the heat-conducting shell 61 to heat it, controlling the temperature between 100-180℃. At the same time, the stepper motor 12 above is started to drive the stirring rod 14 to rotate, thereby quickly mixing the chemical agents with the blended fabric. The polyester is degraded and removed using depolymerizing agents such as ethylene glycol under certain temperature and catalytic conditions, leaving cotton fibers. After the reaction is complete, the discharge valve of the discharge pipe 15 is opened to introduce the alcoholysis agent and cotton fibers into the separation box 3. The alcoholysis agent can flow into the separation tank 3 through the inclined filter plate 8. The alcoholysis liquid is introduced into the alcoholysis liquid recovery frame 5 through the direct connection pipe 4 by the running water pump 16 for recycling, which facilitates subsequent distillation and extraction. On the other hand, the DC motor 9 can be turned on during the separation process. Its motor shaft drives the material feeding plate 11 to rotate through the drive shaft 10. Under the action of inertia, the cotton fibers with solution adhering to them fall to the bottom of the inclined filter plate 8. Then, the operator can put the cotton fibers deposited at the bottom into the fixed sleeve 72, add water to the fixed sleeve 72, and then turn on the stepper motor 73 to drive the material feeding fan blade frame 74 to rotate, thereby thoroughly cleaning the cotton fibers inside to remove residual alcoholysis agent and catalyst. The treated cotton fibers can be used for subsequent processing or as recycled fibers.

[0047] The beneficial technical effects of the waste treatment equipment for polyester-cotton fabric production in this application embodiment are roughly as follows:

[0048] This product utilizes a chemical reaction process. By adding an alcoholysis agent and catalyst to a reaction vessel and stirring and heating it, the polyester in the textile is degraded and removed, leaving cotton fibers. Then, under the dual action of separation tank 3 and cotton fiber cleaning components, the residual alcoholysis agent and catalyst are cleaned and removed, resulting in clean cotton fibers for subsequent processing or use as recycled fibers. This avoids the waste treatment method of direct combustion and heat conversion, making it clean, environmentally friendly, and sustainable.

[0049] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
