[0022] To facilitate understanding of the present invention, the present invention will be described more fully below with reference to the accompanying drawings. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0023] The recycling process of recycled polyester fiber fabrics includes sorting, crushing, washing, drying and melt granulation.

[0024] The broken regenerated polyester fabric pieces enter a hot alkali solution or other cleaning liquid to remove contaminants such as labels, glue, grease and dyes attached thereto. After soaking and stirring, the mixed solution contains clean regenerated polyester fabric pieces and a large number of dirt particles separated from the pieces. The regenerated polyester fabric piece recycling device of the present application separates the regenerated polyester fabric pieces and the dirt particles. The regenerated polyester fabric piece has a greater density than the dirt particles.

[0025] As shown in Figures 1 to 4 The regenerated polyester fabric piece recycling device of the present application comprises a rotating drum 1 and a protective cover 2. The rotating drum 1 is provided with a slag outlet 3. The protective cover 2 is internally provided with a top isolation plate 5. The lower end of the protective cover 2 is provided with a bottom mounting frame 8. The bottom mounting frame 8 is internally provided with a bottom isolation plate 9 matched with the top isolation plate 5. The rotating drum 1 is rotationally matched with the protective cover 2 and the bottom mounting frame 8. When the device is about to be operated, the protective cover 2 covers the bottom mounting frame 8. The protective cover 2 is provided with a handle, which makes it more convenient to open and close the protective cover 2. When the protective cover 2 covers the bottom mounting frame 8, the regenerated polyester fabric pieces thrown out of the rotating drum 1 through the slag outlet 3 are blocked by the protective cover 2, and then the regenerated polyester fabric pieces fall out of the slag outlet at the lower end of the bottom mounting frame 8. The top isolation plate 5 and the bottom isolation plate 9 can ensure that the regenerated polyester fabric pieces do not enter other positions of the device, which affects the operation of the device. The device is more stable when it is operated. The protective cover 2 can also avoid environmental pollution caused by the regenerated polyester fabric pieces thrown out.

[0026] A spiral propeller 10 is rotationally arranged in the rotating drum 1. The spiral propeller 10 is internally provided with a feeding pipe 11. The bottom mounting frame 8 is respectively provided with a first driver 12 and a second driver 13 on both sides. The first driver 12 drives the spiral propeller 10. The second driver 13 drives the rotating drum 1. After the device is started, the first driver 12 drives the spiral propeller 10 to rotate, and the second driver 13 drives the rotating drum 1 to rotate. The rotating direction of the rotating drum 1 is the same as that of the spiral propeller 10, but the rotating speeds of the two are different. Thus, the spiral propeller 10 can push the regenerated polyester fabric pieces close to the inner wall of the rotating drum 1 to the direction of the slag outlet 3 through the relative speed difference. The mixed solution enters the inside of the spiral propeller 10 through the feeding pipe 11. The spiral propeller 10 throws out the mixed solution into the rotating drum 1 when it rotates. The regenerated polyester fabric pieces, dirt particles, impurities and waste water in the mixed solution are layered by the action of centrifugal force when the rotating drum 1 rotates. The regenerated polyester fabric pieces are close to the inner wall of the rotating drum 1, and the dirt particles, impurities and waste water are located on the side far from the inner wall of the rotating drum 1.

[0027] A water outlet 14 is provided at the side end of the drum 1, and a baffle 15 is slidably provided at the side end of the drum 1 at a position corresponding to the water outlet 14. Dirt particles, impurities and wastewater in the drum 1 are discharged from the water outlet 14 by overflow. As dirt particles, impurities and wastewater accumulate in the drum 1, when the liquid level of the dirt particles, impurities and wastewater is higher than the water outlet 14, the dirt particles, impurities and wastewater in the drum 1 are discharged through the water outlet 14. With the assistance of the baffle 15, the height of the water outlet 14 can be controlled, thereby controlling the overflow liquid level in the drum 1.

[0028] When the equipment is used to separate recycled polyester fiber fabric fragments, the high-speed rotating drum 1 will throw the recycled polyester fiber fabric fragments out from the slag outlet 3. The thrown recycled polyester fiber fabric fragments will produce noise when hitting the inner wall of the protective cover 2, and there is still a small amount of hot alkali liquid in the thrown recycled polyester fiber fabric fragments. Some of the recycled polyester fiber fabric fragments will adhere to the inner wall of the protective cover 2. During long-term use, the hot alkali liquid will corrode the inner wall of the protective cover 2, and after the subsequent equipment is shut down, a large amount of water needs to be used to rinse the inner wall of the protective cover 2 to avoid the long-term adhesion of the recycled polyester fiber fabric fragments and the hot alkali liquid causing aggravated corrosion. In order to solve the above problems: like Figures 1 to 9 As shown, in the recycled polyester fiber fabric recycling and processing device of the present invention, a noise reduction assembly 4 is provided on the inner wall of the protective cover 2 at a position corresponding to the slag outlet 3. Multiple noise reduction assemblies 4 are provided. A pressure sensor 7 is provided on the outer surface of the protective cover 2 at a position corresponding to the uppermost noise reduction assembly 4. When recycled polyester fiber fabric fragments are thrown out of the slag outlet 3, if the noise reduction assembly 4 is not present, the recycled polyester fiber fabric fragments will hit the inner wall of the protective cover 2 in a nearly vertical direction, generating the greatest impact noise. However, after the noise reduction assembly 4 is installed, the thrown recycled polyester fiber fabric fragments will hit the noise reduction assembly 4, and the contact angle between the recycled polyester fiber fabric fragments and the noise reduction assembly 4 is between 30° and 45°, thereby reducing the noise generated by the impact of the recycled polyester fiber fabric fragments. As the recycled polyester fiber fabric fragments adhere to the uppermost noise reduction assembly 4, the noise reduction assembly 4 generates pressure on the pressure sensor 7. Therefore, with the assistance of the pressure sensor 7, the number of recycled polyester fiber fabric fragments adhering to the noise reduction assembly 4 can be indirectly determined, thereby facilitating subsequent cleaning work.

[0029] The noise reduction component 4 includes a noise reduction arc plate 401 and a mounting plate 402. The mounting plate 402 is arranged on the inner wall of the protective cover 2. The noise reduction arc plate 401 is rotated and arranged on the mounting plate 402 through a torsion spring. A limiting arc plate 403 is provided on the side of the noise reduction arc plate 401 close to the protective cover 2. A limiting opening 201 is provided on the protective cover 2 at a position corresponding to the limiting arc plate 403. The limiting arc plate 403 passes through the limiting opening 201. A limiting plate 404 is provided at the end of the limiting arc plate 403 on one side of the outer end of the protective cover 2. When the recycled polyester fiber fabric fragments thrown out of the slag outlet 3 hit the noise reduction arc plate 401, the recycled polyester fiber The angle between the moving direction of the recycled polyester fiber fabric fragments and the noise reduction arc plate 401 is between 30° and 45°. Through this non-vertical impact, the noise generated when the recycled polyester fiber fabric fragments come into contact with the noise reduction arc plate 401 can be effectively reduced. When the recycled polyester fiber fabric fragments are thrown out at high speed and hit the noise reduction arc plate 401, due to the presence of the torsion spring, the noise reduction arc plate 401 will be deflected, thereby buffering the impact kinetic energy of the recycled polyester fiber fabric fragments, reducing the damage to the noise reduction arc plate 401 caused by the impact of the recycled polyester fiber fabric fragments, and effectively extending the service life of the noise reduction arc plate 401 and reducing noise.

[0030] The limiting arc plate 403 in the noise reduction component 4 corresponding to the pressure sensor 7 passes through the pressure sensor 7. When the noise reduction component 4 is not turned on, due to the action of the torsion spring in the noise reduction component 4, there is a gap between the limiting plate 404 and the pressure sensor 7. As the equipment continues to operate, the amount of recycled polyester fiber fabric fragments adhering to the noise reduction arc plate 401 will gradually increase. Therefore, the downward superimposed gravity of the uppermost noise reduction arc plate 401 will gradually increase, causing the uppermost noise reduction arc plate 401 to overcome the action of the torsion spring and deflect downward, causing the limiting plate 404 to move downward and contact the pressure sensor 7, thereby increasing the detection value of the pressure sensor 7. Therefore, with the assistance of the pressure sensor 7, the amount of recycled polyester fiber fabric fragments adhering to the noise reduction arc plate 401 can be indirectly judged.

[0031] An auxiliary component 6 is slidingly provided on the top isolation plate 5. The auxiliary component 6 includes a cleaning pipe 601. An inclined drain port 602 is provided on the cleaning pipe 601. The auxiliary component 6 cleans impurities adhered to the noise reduction component 4 during sliding. When the pressure sensor 7 detects that there are too many recycled polyester fiber fabric fragments adhered to the noise reduction arc plate 401, in order to reduce the damage to the noise reduction arc plate 401 caused by corrosion caused by long-term adhesion of the recycled polyester fiber fabric fragments, the auxiliary component 6 will be started. Through the movement of the cleaning pipe 601, the cleaning pipe 601 collides with the noise reduction arc plate 401, causing the noise reduction arc plate 401 to deflect toward the direction of the protective cover 2, and then under the action of the torsion spring, the noise reduction arc plate 401 rebounds. In this way, the recycled polyester fiber fabric fragments adhered to the noise reduction arc plate 401 can be vibrated and shaken off.

[0032] The auxiliary assembly 6 further comprises a sliding block 603, a sliding groove 604 is arranged on the top isolation plate 5, the sliding block 603 slides in the sliding groove 604, the cleaning pipe 601 is rotationally arranged at the side end of the sliding block 603, one end of the sliding groove 604 is provided with a clamping block 605 for limiting the sliding block 603, when the sliding block 603 slides in the sliding groove 604, the sliding block 603 will drive the movement of the cleaning pipe 601, the movement track of the cleaning pipe 601 is the same as that of the sliding groove 604, and it should be noted that, in order to ensure the movement stability of the cleaning pipe 601, the two sides of the cleaning pipe 601 are provided with the sliding block 603 and the sliding groove 604.

[0033] An arc-shaped hydraulic cylinder 606 matched with the sliding groove 604 is arranged at the side end of the bottom isolation plate 9, a clamping hole 607 is arranged on one side of the sliding block 603 close to the output end of the arc-shaped hydraulic cylinder 606, the output end of the arc-shaped hydraulic cylinder 606 is inserted into the clamping hole 607, and there is friction force between the output end of the arc-shaped hydraulic cylinder 606 and the clamping hole 607, after the arc-shaped hydraulic cylinder 606 is started, the output end of the arc-shaped hydraulic cylinder 606 is inserted into the clamping hole 607 of the sliding block 603 by a certain distance, thereby driving the movement of the sliding block 603, when the sliding block 603 moves to the end of the sliding groove 604, with the output end of the arc-shaped hydraulic cylinder 606 extending again by a certain distance, the output end of the arc-shaped hydraulic cylinder 606 is completely inserted into the clamping hole 607 of the sliding block 603, and then the arc-shaped hydraulic cylinder 606 is reversely operated, so that the output end of the arc-shaped hydraulic cylinder 606 is retracted, when the sliding block 603 moves to the clamping block 605, the sliding block 603 cannot move any more, the output end of the arc-shaped hydraulic cylinder 606 is extracted from the clamping hole 607, thereby ensuring that the subsequent protective cover 2 can be smoothly opened.

[0034] A connector 608 is arranged on one side of the cleaning pipe 601 close to the sliding block 603, a water inlet pipe 609 is arranged on the connector 608, the water inlet pipe 609 communicates with the cleaning pipe 601 through the connector 608, the water inlet pipe 609 is an elastic hose, a winding wheel is arranged in the bottom mounting frame 8 to wind and store the water inlet pipe 609, so that the water inlet pipe 609 is released or wound when the sliding block 603 moves, and a limiting frame is arranged at the lower end of the sliding groove 604 at the side end of the top isolation plate 5, the water inlet pipe 609 is blocked by the limiting frame and does not contact the rotating drum 1 when the water inlet pipe 609 is released, the water inlet pipe 609 is limited by the cooperation of the winding wheel and the limiting frame during the movement of the cleaning pipe 601, so that the water inlet pipe 609 does not contact the rotating drum 1 when the cleaning pipe 601 moves, thereby ensuring the stability of the equipment operation, and air or water can be introduced into the cleaning pipe 601 through the water inlet pipe 609, and then the water outlet 602 on the cleaning pipe 601 discharges water or air, under the influence of the reaction force, the cleaning pipe 601 rotates.

[0035] In use, after the device is started, the mixed liquid enters the high-speed rotating spiral propeller 10 through the feed pipe 11, and then enters the rotating drum 1. With the high-speed rotation of the rotating drum 1, solid-liquid separation occurs at the inner wall of the rotating drum 1 under the action of centrifugal force, that is, the regenerated polyester fabric scraps adhere to the inner wall of the rotating drum 1, and the layer of regenerated polyester fabric scraps away from the inner wall of the rotating drum 1 is a layer of dirt particles, impurities and wastewater. Because of the speed difference between the rotating drum 1 and the spiral propeller 10, the regenerated polyester fabric scraps will be pushed towards the direction of the slag outlet 3 with the assistance of the spiral propeller 10, and when the layer of dirt particles, impurities and wastewater exceeds the water outlet 14, the dirt particles, impurities and wastewater will be discharged from the water outlet 14, and the regenerated polyester fabric scraps will be thrown out from the slag outlet 3.

[0036] After the regenerated polyester fabric scraps are thrown out from the slag outlet 3, the regenerated polyester fabric scraps will hit the noise reduction arc plate 401, and the angle between the flight direction of the regenerated polyester fabric scraps and the noise reduction arc plate 401 is between 30° and 45°. Through this non-perpendicular hitting, the hitting noise generated when the regenerated polyester fabric scraps contact the noise reduction arc plate 401 can be effectively reduced. When the regenerated polyester fabric scraps hit the noise reduction arc plate 401 at high speed, the regenerated polyester fabric scraps have kinetic energy. When the regenerated polyester fabric scraps contact the noise reduction arc plate 401, the noise reduction arc plate 401 will be deflected due to the presence of the torsional spring, thereby buffering the hitting kinetic energy of the regenerated polyester fabric scraps. On the one hand, the kinetic energy of the regenerated polyester fabric scraps is weakened, reducing the flight distance. On the other hand, the damage of the regenerated polyester fabric scraps to the noise reduction arc plate 401 is reduced, and the service life of the noise reduction arc plate 401 is improved.

[0037] With the continuous operation of the device, hot lye is still left in the regenerated polyester fabric scraps thrown out from the slag outlet 3. Therefore, part of the regenerated polyester fabric scraps will also adhere to the noise reduction arc plate 401. The downward stacking gravity of the uppermost noise reduction arc plate 401 will gradually increase, causing the uppermost noise reduction arc plate 401 to overcome the action of the torsional spring and deflect downward, causing the limiting plate 404 to move downward and contact the pressure sensor 7, thereby increasing the detection value of the pressure sensor 7.

[0038] When the detection value of the pressure sensor 7 increases and exceeds the set threshold, the device determines that there are too many recycled polyester fiber fabric fragments adhering to the noise reduction arc plate 401. In order to reduce the long-term corrosion of the recycled polyester fiber fabric fragments on the noise reduction arc plate 401, the device controls the arc hydraulic cylinder 606 to start. At the same time, high-pressure air is introduced into the water inlet pipe 609, so that air is sprayed out from the drain port 602 of the cleaning pipe 601, so that the cleaning pipe 601 is in a rotating state. The output end of the arc hydraulic cylinder 606 extends out and is inserted into the card hole 607 of the slider 603, thereby driving the slider 603 to rotate. The movement of the slider 603 will drive the movement of the cleaning tube 601. When the cleaning tube 601 touches the lower end of the noise reduction arc plate 401 during the movement, the noise reduction arc plate 401 will be lifted up, that is, the noise reduction arc plate 401 will overcome the action of the torsion spring and deflect toward the direction of the protective cover 2. After the cleaning tube 601 crosses the noise reduction arc plate 401, the noise reduction arc plate 401 will rotate under the action of the torsion spring. In this way, the noise reduction arc plate 401 will be deflected back and forth, and then the recycled polyester fiber fabric fragments adhering to the noise reduction arc plate 401 will be shaken off to complete the cleaning of the noise reduction arc plate 401.

[0039] At the same time, when the cleaning tube 601 passes through the noise reduction arc plate 401, the high-pressure gas discharged from the drain outlet 602 acts on the noise reduction arc plate 401, and the high-pressure gas can assist in cleaning the recycled polyester fiber fabric fragments adhering to the noise reduction arc plate 401. When the noise reduction arc plate 401 deflects back and forth, the next noise reduction arc plate 401 in the moving direction of the cleaning tube 601 can scrape and clean the limiting arc plate 403 of the previous noise reduction arc plate 401, thereby realizing the cleaning of the recycled polyester fiber fabric fragments adhering to the limiting arc plate 403, thereby improving the convenience of equipment use.

[0040] When the slider 603 moves to the end of the slide groove 604, the equipment will continue to control the output end of the arc hydraulic cylinder 606 to extend the set distance again, so that the output end of the arc hydraulic cylinder 606 will be completely inserted into the card hole 607 of the slider 603, and then the arc hydraulic cylinder 606 will reversely operate to retract the output end of the arc hydraulic cylinder 606, so that the slider 603 starts to move in the opposite direction. During the reverse movement of the slider 603, when the cleaning tube 601 contacts the noise reduction arc plate 401, since the cleaning tube 601 is in a rotating state, the rotation of the cleaning tube 601 causes the lower end of the noise reduction arc plate 401 to move upward through friction, ensuring that the cleaning tube 601 can cross the noise reduction arc plate 401. In this process, the noise reduction arc plate 401 is cleaned again.

[0041] When the slider 603 moves to the clamping block 605 , the slider 603 cannot move any further, and the output end of the arc-shaped hydraulic cylinder 606 is drawn out from the clamping hole 607 , thereby ensuring that the subsequent protective cover 2 can be opened smoothly.

[0042] After the equipment has finished processing the mixed liquid, the equipment needs to be thoroughly cleaned. At this time, the protective cover 2 is opened, the water outlet 14 is adjusted through the baffle 15, and then the protective cover 2 is closed, and clean water is introduced into the feed pipe 11, so that the slag outlet 3 starts to throw out clean water. At the same time, clean water is also introduced into the water inlet pipe 609, and the equipment controls the arc hydraulic cylinder 606 to start reciprocating operation.

[0043] During this process, the clean water thrown out from the slag outlet 3 cooperates with the clean water sprayed from the water outlet 602 of the cleaning pipe 601 to clean the inner wall of the protective cover 2 and the discharge area of ​​the bottom mounting frame 8.

[0044] In the process of the cleaning tube 601 moving along the slide 604, the water flow sprayed from the drain port 602 on the rotating cleaning tube 601 can better clean the noise reduction arc plate 401, and in this process, when the cleaning tube 601 crosses the noise reduction arc plate 401, the reciprocating deflection of the noise reduction arc plate 401 can enable the water flow to clean it better. Through such close water flow cleaning, not only the cleaning effect is improved, but also water resources can be saved. That is, when the inner wall of the protective cover 2 is cleaned only by the water flow thrown out by the slag outlet 3, some dead corners are difficult to clean, and the protective cover 2 needs to be opened for separate cleaning, which is time-consuming, labor-intensive and wastes water resources.

[0045] At the same time, since the recycled polyester fiber fabric fragments adhering to the noise reduction arc plate 401 will be cleaned from time to time during the operation of the equipment, the water consumption can be reduced during the final comprehensive cleaning of the equipment, thereby reducing the waste of water resources by the equipment.

[0046] The main functions achieved by the present invention are: by setting components such as a cleaning pipe 601, a noise reduction arc plate 401, a pressure sensor 7 and an arc-shaped hydraulic cylinder 606, in the process of the equipment separating the recycled polyester fiber fabric fragments in the mixed liquid, the noise of the recycled polyester fiber fabric fragments thrown out of the slag outlet 3 hitting the protective cover 2 can be reduced with the assistance of the noise reduction arc plate 401, and the adhesion amount on the noise reduction arc plate 401 can be indirectly detected with the assistance of the pressure sensor 7, and by controlling the arc-shaped hydraulic cylinder 606, the cleaning pipe 601 is moved to touch the noise reduction arc plate 401, so that the recycled polyester fiber fabric fragments adhered to the noise reduction arc plate 401 can be shaken off, and the drain port 602 of the cleaning pipe 601 discharges high-pressure gas at this time for auxiliary cleaning. At the same time, in the final comprehensive cleaning stage of the equipment, the water flow discharged from the drain port 602 of the cleaning pipe 601 cooperates with the water flow thrown out of the slag outlet 3 to comprehensively clean the equipment, thereby reducing the waste of water resources.

[0047] The installation, connection or setting method of the recycled polyester fiber fabric recycling and processing device of the present invention are all common mechanical methods, and can be implemented as long as they can achieve their beneficial effects.
