Description

Technical Field

[0001] The utility model belongs to the technical field of polyester fabric decolorization, and particularly relates to a device for decolorizing waste polyester fabrics by a distillation method. Background Art

[0002] Polyester fabric is a textile made of polyester as the main raw material. Polyester, also known as polyester fiber, is a synthetic fiber with many excellent properties. Polyester fabric therefore has high strength, high elastic recovery ability, good wear resistance, wrinkle resistance and ironing resistance. It has poor moisture absorption, and may feel a little stuffy when worn, and is prone to static electricity and dust. However, polyester fabric is very easy to dry after washing, and the wet strength hardly decreases, and it has good washable and wearable properties. In addition, polyester fabric has good light resistance and better sun resistance than natural fiber fabrics, especially good sun resistance behind glass. Polyester fabric is also resistant to various chemicals, and is not greatly damaged by acids and alkalis. At the same time, it is not afraid of mildew and insect infestation.

[0003] Decolorization treatment helps to better recycle fiber materials in waste polyester fabrics. After decolorization, the purity of the fibers is improved, which is beneficial to the subsequent reuse or production of regenerated fibers, and then helps to save resources. When decolorizing waste polyester fabrics, since the solvent is prone to precipitation when heated, the solvent needs to be stirred accordingly so that it can be heated evenly for use. In the prior art, the stirring plate for stirring the solvent is fixed as a whole. When it is damaged and disassembled, multiple stirring plates need to be replaced as a whole, which increases the disassembly steps of the staff accordingly, thereby reducing the staff's recovery efficiency of decolorizing and recycling waste polyester fabrics. For this reason, a device for removing the color of waste polyester fabrics by distillation is proposed. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1

[0023] like Figure 1-5As shown, a device for removing the color of waste polyester fabric by distillation method includes a decolorization box 1 and a mounting top plate 2, and also includes: an installation stirring mechanism for uniformly stirring and heating the decolorization solvent inside the decolorization box 1, the installation stirring mechanism is located at the bottom of the decolorization box 1, the installation stirring mechanism includes a mounting bottom plate 9 and a stirring plate 904, the bottom of the mounting bottom plate 9 is fixedly connected to a servo motor 901, the output end of the servo motor 901 is fixedly connected to a rotating shaft 902, and the top of the rotating shaft 902 rotates and extends to the outside of the top of the mounting bottom plate 9, the outer side wall of the rotating shaft 902 is fixedly connected to a rotating block 903, the outer wall of the rotating block 903 is provided with a plurality of plug-in slots, the interior of the plug-in slot is fixedly connected to a reset spring 906, the end of the reset spring 906 away from the plug-in slot is fixedly connected to a limiting plate 907, and one end of the stirring plate 904 is fixedly connected to a limiting plate 907. The end is fixedly connected with a plug-in plate 905, a limited sliding groove is provided on the top of the plug-in plate 905, a socket is provided inside the limited sliding groove, a mounting magnetic block 9013 is fixedly connected inside the socket, a mounting cavity 908 is provided inside the rotating block 903 above the plug-in groove, both sides of the mounting cavity 908 are fixedly connected with tension springs 909, one end of the tension spring 909 away from the mounting cavity 908 is fixedly connected with a sliding plug rod 9010, and the top of the sliding plug rod 9010 slides and extends to the outside of the top of the rotating block 903, the top of the sliding plug rod 9010 is fixedly connected with a pull block 9011, the bottom end of the sliding plug rod 9010 is fixedly connected with a sliding magnetic block 9012, one side of the stirring plate 904 is fixedly connected with the plug-in plate 905, a heating mechanism is installed on the mounting bottom plate 9, and recovery mechanisms are connected on both sides of the decolorization box 1;

[0024] The utility model is further specifically described in detail: the outer wall of the plug-in plate 905 and the inner wall of the plug-in groove are slidably fitted, a plurality of flow holes are opened on the stirring plate 904, the outer wall of the limit plate 907 and the inner wall of the plug-in groove are slidably fitted, the sliding magnetic block 9012 and the mounting magnetic block 9013 are arranged with corresponding opposite poles attracting each other, the outer wall of the sliding rod 9010 is slidably fitted with the inner walls of the limiting slide groove and the plug-in hole respectively, and the pull block 9011 is located on the top outside of the rotating block 903.

[0025] As can be seen from the above, when the staff decolorizes the waste polyester fabric, they first open the installation top plate 2, add the decolorization solvent into the interior of the decolorization box 1, and then install the waste polyester fabric to be decolorized on the outer wall of the installation clamping plate 13. It should be noted that this is a prior art, and its working principle will not be described in detail;

[0026] After the installation of the waste polyester fabric is completed, the installation top plate 2 is installed on the top of the decolorization box 1. At this time, the servo motor 901 and the heating element 102 are turned on to make them work. When the heating element 102 is working, the bottom of the decolorization box 1 can be heated, and the decolorization solvent inside the decolorization box 1 can be heated accordingly. By utilizing the effect of solvent heating, the steam heated by the solvent can be volatilized upward, and the waste polyester fabric above can be steam decolorized;

[0027] When the servo motor 901 is working, it can drive the rotating shaft 902 and the rotating block 903 on its outer wall to rotate. When the rotating block 903 rotates, it can drive the multiple stirring plates 904 on its outer wall to rotate. The rotating action of the stirring plates 904 can rotate and stir the solvent inside the decolorization box 1, so that the decolorization solvent is evenly heated, thereby improving the heating effect of the solvent.

[0028] When the stirring plate 904 is damaged after long-term use and needs to be disassembled and replaced, the installation base plate 9 is first disassembled, and then the pull block 9011 is pulled upward, which accordingly drives the sliding plug rod 9010 to slide upward, so that it is disengaged from the plug hole on the plug plate 905, so that the fixing effect between the plug plate 905 and the plug slot is released. At this time, the limit plate 907 is used to eject the plug plate 905 from the outside of the plug slot according to the action of the return spring 906, and the stirring plate 904 can be disassembled accordingly. Through the setting of this structure, the sliding plug rod 9010 is used to slide and plug in the plug hole, which simplifies the plug-in fixation between the plug plate 905 and the plug slot, and correspondingly simplifies the installation operation of the stirring plate 904, and multiple stirring plates 904 can be disassembled separately, thereby reducing the disassembly steps of the staff, thereby improving the recycling efficiency of the staff for decolorizing and recycling waste polyester fabrics;

[0029] When the plug-in board 905 and the stirring board 904 are plugged and installed, the plug-in board 905 is directly inserted into the plug-in slot, and the limiting slide slot and the sliding plug rod 9010 slide correspondingly, and the sliding magnetic block 9012 at the bottom of the sliding plug rod 9010 slides to the position of the plug hole. According to the effect of the opposite poles of the sliding magnetic block 9012 and the installation magnetic block 9013 attracting each other, the sliding plug rod 9010 can be automatically inserted into the inside of the plug hole, and the plug-in board 905 is plugged and fixed accordingly, so as to fix the stirring board 904;

[0030] It should be noted that: the bottom of the pull block 9011 does not fit with the top of the rotating block 903 in the initial state, so that there is a certain distance between the two. Accordingly, the bottom end of the sliding rod 9010 slides and fits with the bottom of the inner wall of the limiting slide groove in the initial state. When the sliding rod 9010 is inserted into the interior of the socket, the bottom of the pull block 9011 fits with the top of the outer wall of the rotating block 903.

The collection box 6 is connected between the two condensing pipes 5 and is connected to the inside of the condensing pipe 5. The condensing pipe 5 and the connecting pipe 11 are both connected to the inside of the decolorization box 1. The bottoms of the decolorization box 1 and the recovery box 4 are fixedly connected to the supporting legs 3.

[0033] As can be seen from the above, the steam generated by the heating element 102 heating the solvent inside the decolorization box 1 is recovered to the inside of the collection box 6 through the condenser 5 and the second valve 8. After the decolorization process is completed, the first valve 7 is opened to allow the solvent inside the decolorization box 1 to be recovered to the inside of the recovery box 4 through the connecting pipe 11. Through the setting of this structure, the decolorization solvent can be recycled, reducing the waste of resources.

[0036] As can be seen from the above, when the heating element 102 is damaged after long-term use, the pull ring 108 is pulled to pull the fitting baffle 10 downward to separate it from the installation groove 101, and the heating element 102 is moved to the outside of the installation groove 101, and the heating element 102 can be taken out and replaced;

[0037] When installing the heating element 102, the replaced heating element 102 is placed above the fitting baffle 10, and then the fitting baffle 10 is pressed upward, so that the telescopic plate 105 is correspondingly extended and retracted toward the inside of the telescopic sleeve 103. When the magnetic rod 106 and the embedded magnetic block 107 come into contact, the magnetic rod 106 and the embedded magnetic block 107 are attracted to each other by opposite poles, so that the fitting baffle 10 and the inner wall of the installation groove 101 can be stably fitted, so that the heating element 102 can be stably installed. Through the setting of this structure, it is convenient for the staff to disassemble and replace the heating element 102, thereby improving the work efficiency of the staff in decolorizing and recycling waste polyester fabrics.
