After soaking and stirring, the mixed solution contains clean regenerated polyester fabric fragments and a large number of dirt particles separated from the fragments.

The screw conveyor includes a conveyor part conical segment, a feeding bin and a conveyor part cylindrical segment arranged in sequence.

The end ring is arranged at the end of the drum part cylindrical segment away from the drum part conical segment. The end ring and the conveyor part cylindrical segment form a liquid outlet.

[0005] A rotating drum liquid discharge device of a horizontal screw centrifuge in Chinese patent application No. CN201810109304.X includes a rotating drum and a screw unloader rotatingly arranged in the rotating drum.

The bottom end of the first baffle is fixed to the inner wall of the rotating drum. The top end of the first baffle has a first channel with the core shaft. The top end of the second baffle cooperates with the core shaft.

[0006] When the regenerated polyester fabric fragments are separated by using the above-mentioned device, the rotating drum rotating at a high speed will throw the regenerated polyester fabric fragments out of the residue discharge port.

There is still a small amount of hot alkali solution or other cleaning liquid in the thrown regenerated polyester fabric fragments. Some of the regenerated polyester fabric fragments will adhere to the inner wall of the protective cover. In the long-term use, the inner wall of the protective cover will be corroded.

[0033] To facilitate understanding of the present invention, a more complete description will be given 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. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

[0034] The recycling process of the regenerated polyester fabric includes sorting, crushing, cleaning, drying, and melt granulation.

[0035] The crushed regenerated polyester fabric fragments enter a hot alkali solution or other cleaning liquid to remove labels, glue, grease, and dyes attached thereto. After soaking and stirring, the mixture contains clean regenerated polyester fabric fragments and a large number of dirt particles separated from the fragments.

[0036] As shown in Figures 1 to 4 The regenerated polyester fabric recycling device comprises a rotating drum 1 and a protective cover 2, the rotating drum 1 is provided with a slag outlet 3, the inside of the protective cover 2 is further 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 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 run, the protective cover 2 covers the bottom mounting frame 8, the protective cover 2 is provided with a handle, which is more convenient to open and close, when the protective cover 2 covers the bottom mounting frame 8, the regenerated polyester fabric fragments 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 fragments 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 fragments do not enter other positions of the device, affecting the operation of the device, ensuring that the device runs more stably, and the protective cover 2 can also avoid environmental pollution caused by the regenerated polyester fabric fragments being thrown out.

[0037] The inside of the rotating drum 1 is provided with a screw propeller 10, the inside of the screw propeller 10 is provided with a feeding pipe 11, the two sides of the bottom mounting frame 8 are respectively provided with a first driver 12 and a second driver 13, the first driver 12 drives the screw propeller 10, the second driver 13 drives the rotating drum 1, after the equipment is started, the first driver 12 drives the screw propeller 10 to rotate, the second driver 13 drives the rotating drum 1 to rotate, wherein the rotating direction of the rotating drum 1 is the same as that of the screw propeller 10, but the rotating speeds of the two are different, so that the screw propeller 10 can push the regenerated polyester fabric fragments 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 liquid enters the inside of the screw propeller 10 through the feeding pipe 11 first, the screw propeller 10 will throw out the mixed liquid into the rotating drum 1 when rotating, the regenerated polyester fabric fragments and dirt particles, impurities and waste water in the mixed liquid are layered by the action of centrifugal force when the rotating drum 1 rotates, the regenerated polyester fabric fragments 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 away from the inner wall of the rotating drum 1.

[0038] The side end of the rotating drum 1 is provided with a water outlet 14, the side end of the rotating drum 1 is slidingly provided with a baffle 15 at the position corresponding to the water outlet 14, the dirt particles, impurities and waste water in the rotating drum 1 are discharged through the water outlet 14 in the form of overflow, as the accumulation of the dirt particles, impurities and waste water in the rotating drum 1, when the liquid level of the dirt particles, impurities and waste water is higher than that of the water outlet 14, the dirt particles, impurities and waste water in the rotating drum 1 are discharged through the water outlet 14, the height of the water outlet 14 can be controlled by the aid of the baffle 15, so as to control the overflow liquid level height in the rotating drum 1.

[0039] When the regenerated polyester fabric fragments are separated by using the equipment, the rotating drum 1 rotating at high speed will throw out the regenerated polyester fabric fragments from the slag outlet 3, the regenerated polyester fabric fragments will produce noise when hitting the inner wall of the protective cover 2, and there is still a small amount of hot lye in the thrown out regenerated polyester fabric fragments, part of the regenerated polyester fabric fragments will adhere to the inner wall of the protective cover 2, in long-term use, the hot lye will cause corrosion phenomenon to the inner wall of the protective cover 2, and a large amount of water needs to be used to flush the inner wall of the protective cover 2 after the subsequent equipment is stopped, so as to avoid that the long-term adhesion of the regenerated polyester fabric fragments and the hot lye causes the corrosion to be more serious, in order to solve the above problems:

[0040] As Figures 1 to 9As shown, the recycling polyester fabric recycling device of the application is provided with a noise reduction assembly 4 at the position corresponding to the slagging port 3 on the inner wall of the protective cover 2, and the noise reduction assembly 4 is provided with a plurality of noise reduction assemblies 4, and the protective cover 2 is provided with a pressure sensor 7 at the position corresponding to the uppermost noise reduction assembly 4. When the recycled polyester fabric fragments are thrown out of the slagging port 3, if there is no noise reduction assembly 4, the recycled polyester fabric fragments will hit the inner wall of the protective cover 2 in a nearly vertical direction, and the hitting noise generated at this time is the largest. After the installation of the noise reduction assembly 4, the thrown recycled polyester fabric fragments will hit the noise reduction assembly 4, and the contact angle between the recycled polyester fabric fragments and the noise reduction assembly 4 is between 30° and 45°, thereby reducing the noise generated by the hitting of the recycled polyester fabric fragments. With the adhesion of the recycled polyester fabric fragments on the uppermost noise reduction assembly 4, the noise reduction assembly 4 will generate pressure on the pressure sensor 7, so that the number of recycled polyester fabric fragments adhered to the noise reduction assembly 4 can be indirectly judged with the aid of the pressure sensor 7, thereby facilitating the subsequent cleaning work.

[0041] The noise reduction assembly 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 arranged on the mounting plate 402 through a torsional spring, the side of the noise reduction arc plate 401 close to the protective cover 2 is provided with a limiting arc plate 403, the protective cover 2 is provided with a limiting port 201 at the position corresponding to the limiting arc plate 403, the limiting arc plate 403 passes through the limiting port 201, and the end of the side of the limiting arc plate 403 located at the outer end of the protective cover 2 is provided with a limiting plate 404. When the recycled polyester fabric fragments thrown out of the slagging port 3 hit the noise reduction arc plate 401, the angle between the moving direction of the recycled polyester fabric fragments and the noise reduction arc plate 401 is between 30° and 45°. Through this non-vertical hitting, the noise generated when the recycled polyester fabric fragments contact the noise reduction arc plate 401 can be effectively reduced. When the recycled polyester fabric fragments are thrown out at high speed and hit the noise reduction arc plate 401, the noise reduction arc plate 401 will be deflected due to the existence of the torsional spring, thereby buffering the hitting kinetic energy of the recycled polyester fabric fragments, reducing the damage of the hitting of the recycled polyester fabric fragments to the noise reduction arc plate 401, effectively prolonging the service life of the noise reduction arc plate 401 and reducing the noise.

[0042] The limiting arc plate 403 in the noise reduction assembly 4 corresponding to the pressure sensor 7 passes through the pressure sensor 7. When the device is not started, there is a gap between the limiting plate 404 and the pressure sensor 7 in the noise reduction assembly 4 due to the action of the torsion spring. With the continuous operation of the device, the amount of regenerated polyester fabric fragments adhering to the noise reduction arc plate 401 gradually increases. Therefore, the downward stacking gravity of the uppermost noise reduction arc plate 401 gradually increases, so that the uppermost noise reduction arc plate 401 overcomes the action of the torsion spring and deflects downward, so that the limiting plate 404 moves downward and contacts 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 regenerated polyester fabric fragments adhering to the noise reduction arc plate 401 can be indirectly judged.

[0043] The auxiliary assembly 6 is slidably arranged on the top isolation plate 5, and the auxiliary assembly 6 includes a cleaning pipe 601, and the cleaning pipe 601 is provided with an inclined drain port 602. The auxiliary assembly 6 cleans the impurities adhering to the noise reduction assembly 4 during sliding. When the amount of regenerated polyester fabric fragments adhering to the noise reduction arc plate 401 is too much through the auxiliary detection of the pressure sensor 7, in order to reduce the damage of the long-term adhesion of the regenerated polyester fabric fragments to the noise reduction arc plate 401, the auxiliary assembly 6 will be started. Through the movement of the cleaning pipe 601, the cleaning pipe 601 collides with the noise reduction arc plate 401, so that the noise reduction arc plate 401 deflects towards the protective cover 2, and then rebounds under the action of the torsion spring. In this way, the regenerated polyester fabric fragments adhering to the noise reduction arc plate 401 can be vibrated and shaken off.

[0044] The auxiliary assembly 6 further includes a sliding block 603, and the top isolation plate 5 is provided with a sliding groove 604. The sliding block 603 slides in the sliding groove 604. The cleaning pipe 601 is rotatably arranged at the side end of the sliding block 603. One end of the sliding groove 604 is provided with a clamping block 605 to limit the sliding block 603. When the sliding block 603 slides in the sliding groove 604, the sliding block 603 drives the movement of the cleaning pipe 601. The movement trajectory of the cleaning pipe 601 is the same as that of the sliding groove 604. It should be noted that in order to ensure the stability of the movement of the cleaning pipe 601, the cleaning pipe 601 is provided with the sliding block 603 and the sliding groove 604 on both sides.

[0045] The bottom isolation plate 9 side end is provided with an arc-shaped hydraulic cylinder 606 matched with the sliding groove 604, the sliding block 603 is provided with a clamping hole 607 on the side 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 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, thereby driving the movement of the sliding block 603. When the sliding block 603 moves to the end of the sliding groove 604, 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, and then the arc-shaped hydraulic cylinder 606 is reversely operated to retract the output end of the arc-shaped hydraulic cylinder 606. 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.

[0046] The cleaning pipe 601 is provided with a connector 608 on the side close to the sliding block 603, and the connector 608 is provided with a water inlet pipe 609. 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. When the sliding block 603 moves, the water inlet pipe 609 is released or wound. The side end of the top isolation plate 5 is provided with a limiting frame at the lower end of the sliding groove 604. When the water inlet pipe 609 is released, it is blocked by the limiting frame and does not contact the rotating drum 1. During the movement of the cleaning pipe 601, the water inlet pipe 609 is limited by the cooperation of the winding wheel and the limiting frame, so that the water inlet pipe 609 does not contact the rotating drum 1 during the movement of the cleaning pipe 601, ensuring the stability of the equipment operation. Air or water can be introduced into the cleaning pipe 601 through the water inlet pipe 609. Then the water outlet 602 on the cleaning pipe 601 will discharge water or air. Under the influence of the reaction force, the cleaning pipe 601 will rotate.

[0047] During use, after the equipment 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. Under the action of centrifugal force, solid-liquid separation occurs at the inner wall of the rotating drum 1, that is, the regenerated polyester fabric fragments adhere to the inner wall of the rotating drum 1. The side of the regenerated polyester fabric fragment layer away from the inner wall of the rotating drum 1 is a layer of dirt particles, impurities and wastewater. Because there is a speed difference between the rotating drum 1 and the spiral propeller 10, the regenerated polyester fabric fragments will be pushed in the direction of the slag outlet 3 with the assistance of the spiral propeller 10. 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 fragments will be thrown out of the slag outlet 3.

[0048] After the regenerated polyester fabric scraps are thrown out of 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 to reduce 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.

[0049] With the continuous operation of the device, hot alkaline solution still remains in the regenerated polyester fabric scraps thrown out of the slag outlet 3. Therefore, part of the regenerated polyester fabric scraps will also adhere to the noise reduction arc plate 401. The downward stacked gravity of the uppermost noise reduction arc plate 401 will gradually increase, causing the uppermost noise reduction arc plate 401 to deflect downward to overcome the action of the torsional spring, causing the limiting plate 404 to move downward and contact the pressure sensor 7, thereby increasing the detection value of the pressure sensor 7.

[0050] When the detection value of the pressure sensor 7 increases beyond the set threshold value, the device determines that there is too much regenerated polyester fabric scraps adhering to the noise reduction arc plate 401 at this time. In order to reduce the long-term corrosion of the regenerated polyester fabric scraps to the noise reduction arc plate 401, the device controls the arc hydraulic cylinder 606 to start. At the same time, the water inlet pipe 609 will be connected to high-pressure air, causing air to be sprayed into the drain port 602 of the cleaning pipe 601, causing the cleaning pipe 601 to be in a rotating state. The output end of the arc hydraulic cylinder 606 extends into the clamping hole 607 of the sliding block 603, thereby driving the movement of the sliding block 603. The movement of the sliding block 603 will drive the movement of the cleaning pipe 601. When the cleaning pipe 601 touches the lower end of the noise reduction arc plate 401 during movement, the noise reduction arc plate 401 will be lifted, i.e., the noise reduction arc plate 401 will deflect in the direction of the protective cover 2 to overcome the action of the torsional spring. After the cleaning pipe 601 crosses the noise reduction arc plate 401, the noise reduction arc plate 401 will rotate under the action of the torsional spring. In this way, the noise reduction arc plate 401 will undergo reciprocating deflection, thereby shaking off the regenerated polyester fabric scraps adhering to the noise reduction arc plate 401, to complete the cleaning of the noise reduction arc plate 401.

[0051] At the same time, when the cleaning pipe 601 passes through the noise reduction arc plate 401, the high-pressure gas discharged from the drain port 602 acts on the noise reduction arc plate 401, and the high-pressure gas can assist in cleaning the fragments of the regenerated polyester fabric adhering to the noise reduction arc plate 401. When the noise reduction arc plate 401 reciprocally deflects, the next noise reduction arc plate 401 in the moving direction of the cleaning pipe 601 can scrape and clean the limiting arc plate 403 of the previous noise reduction arc plate 401, thereby realizing the cleaning of the fragments of the regenerated polyester fabric adhering to the limiting arc plate 403, and improving the convenience of equipment use.

[0052] When the sliding block 603 moves to the end of the sliding groove 604, the device continues to control the output end of the arc-shaped hydraulic cylinder 606 to extend again by a certain distance, so that 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 reversely operates to make the output end of the arc-shaped hydraulic cylinder 606 retract, so that the sliding block 603 starts to move reversely. During the reverse movement of the sliding block 603, when the cleaning pipe 601 contacts the noise reduction arc plate 401, the cleaning pipe 601 is in a rotating state, and the rotation of the cleaning pipe 601 moves the lower end of the noise reduction arc plate 401 upward through friction, so as to ensure that the cleaning pipe 601 can cross the noise reduction arc plate 401. In this process, the noise reduction arc plate 401 is cleaned again.

[0053] When the sliding block 603 moves to the clamping block 605, the sliding block 603 cannot move any more, and 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.

[0054] After the device completes the treatment of the mixed liquid, the device needs to be comprehensively cleaned. At this time, the protective cover 2 is opened, the baffle 15 is adjusted to the water outlet 14, then the protective cover 2 is closed, and the feed pipe 11 is connected to clean water, so that the slag outlet 3 starts to spray clean water, and the water inlet pipe 609 also starts to spray clean water, and the device controls the arc-shaped hydraulic cylinder 606 to start reciprocating operation.

[0055] In this process, the clean water sprayed by the slag outlet 3 cooperates with the clean water sprayed by the drain port 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.

[0056] In the process of moving the cleaning pipe 601 along the chute 604, the water flow sprayed by the drain port 602 on the rotating cleaning pipe 601 can better clean the noise reduction arc plate 401, and in this process, the reciprocating deflection of the noise reduction arc plate 401 when the cleaning pipe 601 crosses the noise reduction arc plate 401 can make the water flow better clean it. Through such close water flow cleaning, not only the cleaning effect is improved, but also water resources can be saved, that is, when the water flow sprayed by the slagging port 3 is used to clean the inner wall of the protective cover 2, some dead angle positions are difficult to clean, and the protective cover 2 needs to be opened for separate cleaning, which is time-consuming and labor-consuming and wastes water resources.

[0057] At the same time, since the equipment is operated to clean the regenerated polyester fiber fabric fragments adhered to the noise reduction arc plate 401 at irregular intervals, the water consumption can be reduced during the final overall cleaning of the equipment, and the waste of water resources by the equipment is reduced.

[0058] The main function realized by the present application is that: by arranging the cleaning pipe 601, the noise reduction arc plate 401, the pressure sensor 7 and the arc-shaped hydraulic cylinder 606 and other components, in the process of separating the regenerated polyester fiber fabric fragments in the mixed liquid by the equipment, the noise reduction arc plate 401 can assist in reducing the noise of the regenerated polyester fiber fabric fragments sprayed by the slagging port 3 hitting the protective cover 2, the pressure sensor 7 can indirectly detect the adhesion amount on the noise reduction arc plate 401, and the arc-shaped hydraulic cylinder 606 is controlled to move the cleaning pipe 601 to touch the noise reduction arc plate 401, so that the regenerated 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 to assist cleaning at this time. At the same time, in the final overall cleaning stage of the equipment, the water flow discharged by the drain port 602 of the cleaning pipe 601 cooperates with the water flow sprayed by the slagging port 3 to clean the equipment, which reduces the waste of water resources.

[0059] The installation mode, connection mode or setting mode of the regenerated polyester fiber fabric recycling device of the present application are all common mechanical modes, and any mode that can achieve the beneficial effects can be implemented.
