The lifting mechanism 381 and the hook 382 cooperate with each other to enter the reactor 32 and hook the fabric deposited at the bottom of the reactor 32. The material cleaning device 38 is arranged opposite to the third conveyor belt 31.

[0057] So, like Figure 5 As shown, through the lifting mechanism 381 and the hook 382, ​​when the lifting mechanism 381 is in the retracted state, the hook 382 is stored in the placement tube 383, and the placement tube 383 is fixed on the bracket; when the lifting mechanism 381 is raised, the hook 382 moves upward, and the end of the hook 382 droops due to gravity, spreads out to the surroundings and rests on the bottom of the reactor 32. The number of the hooks 382 is not less than 8.

[0058] In this embodiment, a third pipe 391 is provided on the first pipe 36, specifically located between the first valve 361 and the delivery pump 35, one end of the third pipe 391 is connected to the lower part of the collection tank 33, and the other end of the third pipe 391 is connected to the first pipe 36, and a third valve 393 is provided on the third pipe 391. Further, a sixth valve 396 is provided between the third valve 393 and the delivery pump 35 for discharging waste liquid or extracting liquid.

[0059] A seventh valve 397 is provided on the second pipeline 37 near the delivery pump 35, and a fourth pipeline 392 is provided. The fourth pipeline 392 is specifically located between the second valve 371 and the delivery pump 35.

At the same time, a fourth valve 394 is provided on the fourth pipeline 392.

[0060] The collecting tank 33 is provided with a vent valve on the top to communicate with the outside air. In addition, the collecting tank 33 is also provided with a fifth pipe on the top, the top of the reaction kettle 32 is connected to the inlet of the condenser 40 through the connecting pipe 39, the outlet of the condenser 40 is connected to the top of the collecting tank 33 through the fifth pipe, the fifth pipe is provided with an eighth valve, and the connecting pipe 39 is provided with a fifth valve 395, the solvent volatilized in the reaction kettle 32 is liquefied through the condenser 40 and introduced into the collecting tank 33.

[0061] The vaporization temperature of the disintegrating agent is low, and a heating jacket is provided around the tank body of the reaction kettle 32 to heat and dry the fabric in the reaction kettle 32 or to vaporize the residual solvent in the reaction kettle 32 .

[0062] like Figure 4 and Figure 5 As shown, the specific principle of the immersion separation unit 3 is as follows:

[0063] Before using the immersion separation unit 3, make sure that all valves are closed except for the vent valve which is normally open.

[0064] Open the fifth valve 395, the eighth valve, or open the second valve 371, the fourth valve 394, or open the fifth valve 395, the eighth valve, the second valve 371, the fourth valve 394 at the same time, and then open the nitrogen valve 322 to add nitrogen to the reactor 32 and the collection tank 33 to replace the gas in the reactor 32, the collection tank 33 and all pipelines.

[0065] After the gas replacement is completed, the nitrogen valve 322 is closed, the vent valves of the reactor 32 and the collection tank 33 are closed, the polyester laminated cloth rags are fed into the hopper 321 of the reactor 32 through the second conveyor belt 21, and the feed valve is closed. The sixth valve 396, the delivery pump 35, and the second valve 371 are opened, and the organic solvent (debonding agent) enters the upper part of the reactor 32 through the sixth valve 396, the first pipeline 36, the delivery pump 35, the second pipeline 37, and the second valve 371. At this time, the fourth valve 394 should be ensured to be closed. After the debonding agent is introduced, the sixth valve 396, the second valve 371, and the delivery pump 35 are closed.

[0066] The agitator 34 is started to promote the separation of the laminated fabrics and the reaction between the laminated fabrics and the adhesive dissolving agent; the condenser 40 is turned on to liquefy the organic solvent volatilized in the reaction kettle 32 through the condenser 40 and introduce it into the collection tank 33.

[0067] After the reaction is completed, the agitator 34 is turned off, the first valve 361, the delivery pump 35, and the fourth valve 394 are opened, and the organic solvent in the reaction kettle 32 is pumped into the collection tank 33. The organic solvent enters the upper part of the collection tank 33 through the first valve 361, the first pipeline 36, the delivery pump 35, the second pipeline 37, the fourth valve 394, and the fourth pipeline 392.

[0068] The heating jacket is started to dry the laminated cloth, and the residual solvent is vaporized and re-liquefied through the condenser 40 and enters the collection tank 33. The organic solvent enters the upper part of the collection tank 33 through the fifth valve 395, the connecting pipe 39, the condenser 40, and the fifth pipe.

[0069] The dried cloth can be taken out through the cleaning channel 324. The cleaning device 38 hooks the cloth at the bottom of the reactor 32 to the third conveyor belt 31 through the cleaning channel 324 and enters the next process to realize automated production. At the same time, it can also reduce the contact of workers with chemical reagents and ensure their health.

[0070] The used organic solvent may contain some impurities such as dyes, adhesives, and rag fibers. The third valve 393, the delivery pump 35, and the second valve 371 are opened to reintroduce the organic solvent in the collection tank 33 into the reactor 32, and the organic solvent is regenerated by heating the jacket distillation and cooling the condenser 40 to reduce the consumption of the solvent.

[0071] Nitrogen is an inert gas and is used as a protective gas. It is introduced into the reactor 32 to exhaust air (especially oxygen, which is chemically more active) to prevent the components in the disintegrator from reacting with oxygen, which may cause the pipeline or container to rupture.

[0072] According to the rules summarized in the experiment, the laminating cloth will be completely separated within 5 minutes, and whether the reaction is completed can also be judged by observing whether the laminating cloth in the reaction kettle 32 is separated.

[0073] After the debonding agent is circulated 2-3 times, the debonding effect is weakened, and the organic solvent in the collection tank 33 can be discharged through the third pipeline 391, the third valve 393, and the sixth valve 396. The organic solvent in the fourth pipeline 392 and the second pipeline 37 can be discharged through the fourth valve 394 and the seventh valve 397.

The lifting machine 43 is used to extract the cloth at the bottom of the water trough 41.

[0075] The left side of the water tank 41 is a feeding end, and the right side of the water tank 41 is a discharging end.

[0076] The polyester laminated cloth scraps are separated and dried in the reaction container to obtain separated polyester cloth and sponge; the polyester cloth and sponge enter the water flotation device through the third conveyor belt 31, the polyester cloth is quickly wetted in the flotation liquid, and sinks into the water tank 41, and is discharged through the material lifter 43; the sponge floats on the liquid surface due to its loose and porous structure containing a large amount of air, and is discharged by the hollow scooping drum 42 under the push of the material rake 44, so as to achieve the separation of polyester cloth and sponge.

[0077] The water tank 41 is pre-filled with flotation liquid, which is a water solution with a certain amount of surfactant added thereto, in order to quickly wet the input materials with water and complete separation.

[0080] The materials to be sorted are put into the feeding end of the water tank 41, and as more than two material rakes 44 rotate, they push the materials to move to the hollow scoop drum 42 at the other end of the water tank 41. In this process, the materials are gradually soaked by water, and the cloth sinks to the bottom of the water tank 41, while the sponge still floats on the water surface and is collected by the hollow scoop drum 42 and transferred out of the water tank 41 and falls into the floating material frame 45; while the cloth at the bottom of the water tank 41 is extracted by the lifting machine 43.
