[0038] For ease of explanation, Figures 1 to 3 middle, Figures 6 to 9 As shown by the arrow, the direction of arrow Y is the vertical direction.

[0039] According to some embodiments of the present application, please refer to Figures 1 to 9 The present embodiment relates to a reaction recovery device 100 for fabrics, comprising a reactor 1, a stirrer 6, a collecting tank 2 and a pipeline mechanism 3. The reactor 1 is used to contain an organic solvent and provide a reaction for the fabrics; a stirring blade 62 of the stirrer 6 extends into the reactor 1, and the stirrer 6 is used to stir the inside of the reactor 1; the collecting tank 2 is used to collect and store the organic solvent; the pipeline mechanism 3 is respectively connected to the reactor 1 and the collecting tank 2, and the pipeline mechanism 3 is used to connect the reactor 1 with the collecting tank 2.

[0040] The organic solvent is the debonding agent, which is used to soak the fabric to make the adhesive of the fabric ineffective, separate the sponge and the fabric, and recover the excess debonding agent, which enters the collection tank 2. The principle of the organic solvent (debonding agent) is a conventional technical means and will not be repeated here. The debonding agent can be reused 2-3 times, then discharged, and new debonding agent can be added again.

[0041] The stirrer 6 includes a stirring blade 62 extending into the interior of the reactor 1 and a stirring motor 61 connected to the stirring blade 62 . The stirring motor 61 is located outside the reactor 1 and provides power for the stirring blade 62 .

[0042] The technical solution of the present application provides a collection tank 2 specifically for recovering organic solvents, thereby preventing workers from directly contacting the organic solvents and recovering the organic solvents, which does not affect the environment and saves costs. On the other hand, the stirring device 6 can be provided to make the fabric react better with the organic solvent, thereby accelerating the completion of the reaction.

[0043] According to some embodiments of the present application, optionally, the pipeline mechanism 3 includes a first pipeline 31, a delivery pump 32, a second pipeline 33, a third pipeline 34 and a fourth pipeline 35, the first pipeline 31 is provided with a first valve 311, the second pipeline 33 is provided with a second valve 331, the third pipeline 34 is provided with a third valve 341, and the fourth pipeline 35 is provided with a fourth valve 351, one end of the first pipeline 31 is connected to the lower part of the reactor 1, the other end of the first pipeline 31 is connected to the inlet of the delivery pump 32, one end of the second pipeline 33 is connected to the outlet of the delivery pump 32, the other end of the second pipeline 33 is connected to the upper part of the reactor 1, the third pipeline 34 is connected to the first pipeline 31, and is located between the first valve 311 and the delivery pump 32, one end of the fourth pipeline 35 is connected to the second pipeline 33, and is located between the delivery pump 32 and the second valve 331, and the other end of the fourth pipeline 35 is connected to the upper part of the collection tank 2.

[0044] The external organic solvent can be transported into the reaction kettle 1 by arranging pipelines (the third pipeline, the first pipeline and the second pipeline) in cooperation with the delivery pump 32, thereby preventing the staff from directly contacting with the organic solvent.

[0045] According to some embodiments of the present application, optionally, Figure 1 , Figure 3 and Figure 7 As shown, the pipeline mechanism 3 also includes a fifth pipeline 36 and a condenser 37. One end of the fifth pipeline 36 is connected to the upper part of the reactor 1, and the other end of the fifth pipeline 36 is connected to the upper part of the collecting tank 2. The condenser 37 is installed on the fifth pipeline 36. The fifth pipeline 36 is provided with a fifth valve 361 and an eighth valve 362. The fifth valve 361 is arranged at the outlet of the condenser 37, and the eighth valve 362 is arranged at the inlet of the condenser 37.

[0046] The condenser 37 is mainly used to condense gas into liquid. When the fabric inside the reactor 1 reacts with the organic solvent, it will volatilize. The volatilized organic solvent is condensed into liquid by the condenser 37 and then recovered to the collection tank 2, so that the organic solvent can be further recovered to avoid waste of the organic solvent. Specifically, in actual use, when the organic solvent is introduced into the reactor 1, the fifth valve 361 and the eighth valve 362 can be opened.

[0047] According to some embodiments of the present application, optionally, Figure 1 , Figure 3 and Figure 7 As shown, the inner wall of the reactor 1 is further provided with a heating jacket 11 , and the heating jacket 11 is used to heat and dry the cloth in the reactor 1 or to gasify the residual organic solvent in the reactor 1 .

[0048] The heating jacket 11 can heat and dry the laminated cloth on one hand, and can gasify the residual solvent on the other hand, and re-liquefy it through the condenser 37 and enter the collection tank 2.

[0049] According to some embodiments of the present application, optionally, Figure 1 , Figure 3 , Figure 8 and Fig. 9 As shown, the pipeline mechanism 3 also includes a sixth pipeline 38, one end of the sixth pipeline 38 is connected to the first pipeline 31 and is located between the first valve 311 and the delivery pump 32, the other end of the sixth pipeline 38 is connected to the lower part of the collection tank 2, and a sixth valve 381 is arranged on the sixth pipeline 38.

[0050] By providing the sixth pipe 38, the organic solvent in the collection tank 2 can be introduced into the reaction kettle 1 (the organic solvent can be reused 2-3 times before it loses its effect). Figure 8 As shown, the sixth valve 381 and the second valve 331 are opened, and the third valve 341 is closed. The organic solvent in the collection tank 2 enters the first pipeline 31 through the sixth pipeline 38, and is then transported to the second pipeline 33 through the delivery pump 32, and finally enters the reactor 1. On the other hand, when the organic solvent in the collection tank 2 cannot function, it can be discharged to the outside through the sixth pipeline 38. Specifically, Fig. 9 As shown, the sixth valve 381 and the third valve 341 are opened, and the organic solvent in the collection tank 2 enters the first pipeline 31 through the sixth pipeline 38 and is finally discharged to the outside from the third pipeline 34 .

[0051] According to some embodiments of the present application, optionally, Figure 1 , Figure 2 and Fig. 9 As shown, the pipeline mechanism 3 further includes a seventh pipeline 39 , which is connected to the second pipeline 33 and is located between the delivery pump 32 and the second valve 331 . A seventh valve 391 is provided on the seventh pipeline 39 .

[0052] The organic solvent remaining in the pipeline is discharged to the outside by setting the seventh pipeline 39. Specifically, when the organic solvent needs to be discharged, the second valve 331, the fourth valve 351 and the seventh valve 391 are opened, and the organic solvent in the second pipeline 33 and the fourth pipeline 35 can be discharged to the outside through the seventh pipeline 39.

[0053] According to some embodiments of the present application, optionally, Figure 1 and Figure 3 As shown, a filter screen 16 is provided at the bottom of the reactor 1, and the filter screen 16 is used to filter excess organic solvent on the cloth.

[0054] By providing the filter 16 to filter the excess organic solvent on the cloth, the cloth can be dried faster on the one hand, and the organic solvent can be recovered as much as possible on the other hand.

[0055] According to some embodiments of the present application, optionally, Figure 1 and Figure 2 As shown, the reactor 1 is provided with a drainage hole 15 at the cleaning channel 14 , and the height of the drainage hole 15 along the vertical direction Y is higher than the height of the connection between the first pipeline 31 and the lower part of the reactor 1 along the vertical direction Y.

[0056] During the normal reaction of the reactor 1, it is necessary to ensure that the cleaning channel 14 is in a closed state. Therefore, the reaction recovery device 100 for cloth also includes a plugging member 7, which is used to plug the cleaning channel 14. Among them, the plugging member 7 can be a conventional plug or a plugging cover, etc. When the cleaning channel 14 is in a closed state and the organic solvent in the reactor 1 needs to be recovered to the collection tank 2 or discharged to the outside, in order to ensure that the organic solvent at the cleaning channel 14 of the reactor 1 can also flow out through the first pipe 31, the reactor 1 is provided with a drainage hole 15 at the cleaning channel 14, and the height of the drainage hole 15 along the vertical direction Y is higher than the height of the connection between the first pipe 31 and the lower part of the reactor 1 along the vertical direction Y, thereby ensuring that the organic solvent at the cleaning channel 14 can flow out.

[0057] According to some embodiments of the present application, optionally, Figures 1 to 5 As shown, a cleaning channel 14 is provided at the lower part of the reactor 1, and the reaction recovery device 100 for cloth also includes a cleaning device 4, which enters the interior of the reactor 1 through the cleaning channel 14; the cleaning device 4 includes a lifting mechanism 41 and a hook 42, and the hook 42 is arranged on the lifting mechanism 41, and the lifting mechanism 41 and the hook 42 cooperate with each other to enter the interior of the reactor 1 and hook the cloth accumulated at the bottom of the reactor 1.

[0058] The lifting mechanism 41 can be an existing lifting device, such as a telescopic rod or a lifting platform. A hook 42 is provided on the lifting mechanism 41, and the number and position of the hook 42 (which can be evenly distributed) can be determined according to actual conditions. Preferably, the number of the hooks 42 is not less than 8, and the hooking effect is better. Among them, the lifting mechanism 41 can hook the cloth by lifting and controlling the hook 42. Specifically, when the lifting mechanism 41 is raised, the hook 42 moves upward accordingly, and the end of the hook 42 droops due to gravity, spreads out and rests on the bottom of the reactor 1 to hook the cloth. When the lifting mechanism 41 is retracted, the hook 42 needs to be retracted, so that the cloth is recovered through the cleaning channel 14 under the action of the hook 42. Optionally, when a filter screen 16 is provided at the bottom of the reactor 1, the cloth is accumulated on the filter screen 16. Therefore, when the hook 42 is spread out to the surroundings, it can be placed on the filter screen 16 to hook the cloth.

[0059] According to some embodiments of the present application, optionally, Figures 3 to 5 As shown, the material cleaning device 4 also includes a conveyor belt 43, a mounting bracket 44 and a placement cylinder 45. The conveyor belt 43 is provided with a mounting bracket 44, and a lifting mechanism 41 is installed on the mounting bracket 44. The placement cylinder 45 is fixed on the mounting bracket 44 and is sleeved outside the hook 42. The placement cylinder 45 is used to store the hook 42.

[0060] In order to store the hook 42 and recycle the cloth, a mounting bracket 44 and a placement tube 45 fixed to the mounting bracket 44 are provided. In actual use, the cleaning channel 14 is in an open state (i.e., the blocking member 7 is removed), and the cleaning device 4 is located below the cleaning channel 14. At this time, if Figure 5 As shown, the lifting mechanism 41 is in the retracted state, and the hook 42 is stored in the placement tube 45. When the cleaning device 4 needs to hook the cloth, the lifting device is controlled to rise, and the hook 42 moves upward accordingly. The end of the hook 42 droops due to gravity, spreads out to the surroundings and rests on the bottom of the reactor 1. Finally, the lifting device is controlled to be retracted, and the hook 42 moves downward accordingly, while hooking the cloth. When the hook 42 is stored in the placement tube 45, the cloth falls onto the conveyor belt 43 and can be transported to the next step through the conveyor belt 43.

[0061] According to some embodiments of the present application, optionally, Figure 1 and Figure 3 As shown, a feeding hopper 5 is provided on the upper part of the reactor 1, and the feeding hopper 5 is connected to the internal space of the reactor 1. A feeding valve 51 is provided on the feeding hopper 5. A nitrogen valve 131 connected to external nitrogen and a safety valve 121 for pressure relief are also provided on the upper part of the reactor 1.

[0062] Optionally, a nitrogen valve 131 is provided on a nitrogen pipe 13, one end of which is connected to the upper part of the reactor 1, and the other end of which is used to be connected to external nitrogen. A safety valve 121 is provided on a first vent pipe 12, one end of which is connected to the upper part of the reactor 1, and the other end of which is connected to the external air, for discharging the air in the reactor 1. In some embodiments, a second vent pipe 21 is further provided on the upper part of the collecting tank 2, and a vent valve 211 is provided on the second vent pipe 21, and the second vent pipe 21 is used to discharge the air in the collecting tank 2. While discharging the air in the reactor 1 and the collecting tank 2, nitrogen is introduced through the nitrogen pipe 13 to achieve gas replacement.

[0063] The cloth can be fed through the feeding hopper 5 and the feeding valve 51. The nitrogen valve 131 is used to add nitrogen to the reactor 1. Nitrogen is an inert gas and is used as a protective gas. It is introduced into the reactor 1 to exhaust air (especially oxygen with relatively active chemical properties), thereby preventing the components in the organic solvent from reacting with oxygen, which may cause the pipeline or container to rupture. The safety valve 121 will release the pressure when the pressure of the reactor 1 is too high.

[0064] According to some embodiments of the present application, optionally, Figure 1 and Figure 3 As shown, a cleaning hole 17 is also provided on the side of the reactor 1 , and the residual solid impurities in the reactor 1 can be cleaned through the cleaning hole 17 .

[0065] According to some embodiments of the present application, optionally, Figure 1 and Figure 3 As shown, a viewing mirror 22 is provided on the side of the collecting tank 2, through which the capacity of the organic solvent in the collecting tank 2 can be observed.

[0066] The specific principle of the reaction recovery device 100 for cloth is as follows:

[0067] Before the reaction recovery device 100 for cloth is used, except for the vent valve 211 of the reactor 1 and the collection tank 2, which is kept normally open, confirm that all other valves are closed. After that, open the second valve 331, the fourth valve 351, or open the fifth valve 361, the eighth valve 362, or open the second valve 331, the fourth valve 351, the fifth valve 361, and the eighth valve 362 at the same time to allow air to circulate in the reactor 1 and the collection tank 2. Then open the nitrogen valve 131, and the external nitrogen enters the reactor 1 and the collection tank 2 through the nitrogen pipe 13 to replace the gas in the reactor 1 and the collection tank 2. After the gas replacement is completed, close the nitrogen valve 131 and the vent valve 211, open the feed valve 51, and add the cloth to be reacted into the reactor 1 through the feeding hopper 5. After the addition is completed, close the feed valve 51.

[0068] like Figure 6 and Figure 7As shown, the third valve 341, the delivery pump 32 and the second valve 331 are opened, and the external organic solvent flows into the first pipe 31 through the third pipe 34, and then is delivered to the second pipe 33 by the delivery pump 32, and finally enters the reactor 1 to react with the fabric to be reacted. When the organic solvent enters the reactor 1, it is necessary to ensure that the fourth valve 351 is in a closed state. After the organic solvent is introduced, the third valve 341, the delivery pump 32 and the second valve 331 are closed. After that, the stirrer 6 is started to promote the separation of the laminated fabrics. While the laminated fabrics and the organic solvent react, the fifth valve 361, the eighth valve 362 and the condenser 37 are ensured to be in an open state. The condenser 37 liquefies the organic solvent volatilized during the reaction of the reactor 1 and introduces it into the collection tank 2. When the organic solvent and the fabric to be reacted have completed the reaction (according to the rules summarized in the experiment, the fabric will be completely separated within 5 minutes, and whether the reaction is completed can also be judged by observing whether the fabric in the reactor 1 is separated), the agitator 6 is turned off, the first valve 311, the delivery pump 32, and the fourth valve 351 are opened, and the second valve 331, the third valve 341 and the seventh valve 391 are ensured to be in a closed state, and the excess organic solvent flows into the collection tank 2 after passing through the first pipe 31, the delivery pump 32, the second pipe 33 and the fourth pipe 35, and the collection tank 2 recovers the excess organic solvent.

[0069] The heating jacket 11 is started to dry the fabric and vaporize the residual organic solvent. At this time, the fifth valve 361, the eighth valve 362 and the condenser 37 are ensured to be in the open state. The vaporized organic solvent is reliquefied under the action of the condenser 37 and enters the collection tank 2 through the fifth pipe 36.

[0070] Open the blocking piece 7 to open the cleaning channel 14. The cleaning device 4 hooks the cloth at the bottom of the reactor 1 onto the conveyor belt 43 through the cleaning channel 14 and enters the next process to realize automated production.
