Description

Technical Field

[0001] This utility model relates to the field of waste recycling technology, specifically a hot-melt recycling and processing device for waste polyester fabric. Background Technology

[0002] The hot melt recycling treatment device is a special equipment that processes specific types of solid waste by heating and melting it, transforming it into reprocessable raw materials. It is mainly concentrated in industrial fields that generate corresponding waste and professional recycling and treatment sites, as well as some polymer material production enterprises that need to internally process waste. It aims to reduce the amount of waste landfill and incineration, reduce resource waste, and at the same time provide enterprises with low-cost recycled raw materials, thus contributing to the circular economy.

[0003] A search revealed Chinese patent publication (CN218872445U), which includes "a crushing chamber and a recycling shell, wherein the crushing chamber is connected to the recycling shell, a baffle is provided at the connection position between the crushing chamber and the recycling shell, two sets of symmetrically arranged buffer plates are fixed inside the crushing chamber, a crushing structure is provided below the two sets of buffer plates, two sets of symmetrically arranged discharge ports are provided below the crushing structure, a recycling drawer is provided below the discharge ports, a collection box is provided below the recycling drawer, a crushing component is provided inside the recycling shell, a feed inlet for discharging waste is opened at the top of the recycling shell, and an input port is opened at the top of the crushing chamber. The crushing component can crush waste materials fed into the recycling shell through the feed inlet." The above-mentioned patent proposes to use a crushing structure and crushing components to crush polyester fabric waste twice, thereby improving the crushing effect. However, since the polyester fabric waste is melted before crushing, some polyester fabric waste still contains glue and sticks together after the first crushing. After the second crushing, the crushing effect is still not good, which affects the recycling and treatment of polyester fabric waste. Therefore, we propose a hot melt recycling and treatment device for chemical fiber polyester fabric waste. Summary of the Invention

[0004] To address the aforementioned technical problems, this application provides a hot-melt recycling and processing device for waste polyester fabric, comprising a recycling chamber, a conical inlet at the top of the recycling chamber, a heating chamber at the top of the conical inlet, a guide port outside the heating chamber, a separation component inside the recycling chamber, a disassembly component inside the recycling chamber, an inlet at the top of the recycling chamber, an outlet outside the recycling chamber, a first crushing component inside the recycling chamber, a second crushing component inside the recycling chamber, and multiple supports at the bottom of the recycling chamber.

[0005] In some embodiments, the separation assembly includes a base plate, the outside of which is disposed inside the recovery chamber. Two vertical plates are disposed on the top of the base plate. Two horizontal rails are slidably connected inside each of the vertical plates. A spring a is sleeved on the outside of each of the horizontal rails. A support frame is disposed on the outside of each horizontal rail.

[0006] In some embodiments, the support frame has two vertical rails slidably connected inside, and two fixing blocks slidably connected outside the two vertical rails. Two springs b are respectively sleeved on the outside of each vertical rail. Two rotating columns are rotatably connected inside the fixing block, and two centrifugal blocks are respectively provided on the outside of each rotating column.

[0007] In some embodiments, a connecting plate is provided on the top of the fixing block, a top plate is provided on the top of the connecting plate, the outside of the fixing block is slidably connected to the inside of the support frame, and the outside of the fixing block is slidably connected to the adjacent side of the two springs b.

[0008] In some embodiments, the disassembly assembly includes a plurality of bolts, the external threads of which are connected to the interior of the recovery chamber. The external threads of the plurality of bolts are connected to a U-shaped pressure plate. A cloth is disposed at the bottom of the U-shaped pressure plate, and a separation plate is disposed inside the cloth. The bottom of the separation plate is disposed at the top of the top plate.

[0009] In some embodiments, the first crushing assembly includes a motor a, the motor a is disposed outside the recovery chamber, the drive end of the motor a is provided with an electric shaft, the electric shaft is provided with a drive gear, a crusher is provided outside the electric shaft, a connecting rod is rotatably connected inside the recovery chamber, and a driven gear is provided outside the connecting rod.

[0010] In some embodiments, the outside of the pulverizer is rotatably connected to the inside of the recycling chamber, and the outside of the driven gear is meshed with the outside of the driving gear.

[0011] In some embodiments, the second crushing assembly includes a motor b, which is externally connected to the outside of the recycling chamber. The drive end of the motor b is provided with a connecting shaft, and a crusher is externally provided to the connecting shaft. The crusher is externally rotatably connected to the inside of the recycling chamber.

[0012] This utility model has at least the following beneficial effects: 1. Polyester waste enters the heating chamber through the feed inlet for preheating and softening. Then, the bidirectional motor in the fixed block drives the centrifugal block to rotate at high speed, generating centrifugal force to separate the polyester fabric waste that is stuck together with glue. The recycling chamber has a groove on the top plate to prevent the separation component from affecting the first and second crushing components when it vibrates. The gap between the fabric sealing plate and the separation plate prevents fine impurities from leaking in. The fabric and the separation plate can be removed separately to separate the composite polyester fabric waste that is stuck together with glue, which is convenient for subsequent crushing, ensuring crushing quality and ensuring continuous and stable operation of the device.

[0013] 2. Start motor a drives the electric shaft to rotate, which in turn drives the active gear and driven gear to mesh and transmit power, coarsely crushing large pieces of polyester waste into smaller pieces. This solves the problem of large pieces of waste easily clogging when directly entering subsequent processes. Subsequently, start motor b drives the toothed roller of the crusher to rotate at high speed through the connecting shaft, which performs secondary extrusion and shearing on the small pieces of waste after coarse crushing, refining them into even smaller particles. This ensures that the waste has a uniform shape. The coarse crushing process reduces the difficulty of processing large pieces of waste, increases the heat-receiving area of ​​the waste, shortens the heat melting time, and reduces energy consumption.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1: Please refer to Figures 1 to 4 This utility model provides a technical solution: a thermal melting recycling device for waste polyester fabric, including a recycling chamber 1, which is the core bearing and processing chamber of the entire device, featuring high temperature and corrosion resistance. A conical feed inlet 2 is provided at the top of the recycling chamber 1, employing a conical structure that is wider at the top and narrower at the bottom to guide the waste material to fall in a concentrated manner, preventing waste from accumulating and clogging at the inlet. A heating chamber 3 is provided at the top of the conical feed inlet 2, which is a sealed chamber for preheating and softening the incoming polyester waste. Preheating the polyester waste in the heating chamber 3 before thermal melting reduces the cutting resistance of the subsequent crushing components and reduces energy consumption during the thermal melting stage. A guide port 4 is provided outside the heating chamber 3, through which the waste material enters the heating chamber 3 during operation. The inner... The unit is equipped with a separation component 5 for separating impurities from the crushed polyester scrap. The inside of the recovery chamber 1 is equipped with a disassembly component 6 for easy replacement and cleaning of the connecting structure. The top of the recovery chamber 1 has an inlet 7 for allowing the heated polyester waste to enter the subsequent process. The outside of the recovery chamber 1 has an outlet 8 for discharging the separated and purified polyester scrap. The inside of the recovery chamber 1 is equipped with a first crushing component 9 for cutting large pieces of polyester waste into smaller pieces. The inside of the recovery chamber 1 is equipped with a second crushing component 10 for further crushing the coarsely crushed small pieces of waste into even smaller fine particles. The bottom of the recovery chamber 1 is equipped with multiple supports 11 to support the weight of the entire device and prevent the bottom of the recovery chamber 1 from directly contacting the ground, which could lead to corrosion and wear.

[0018] The separation assembly 5 includes a base plate 51 for supporting the top fixed structure. The base plate 51 is located inside the recovery chamber 1. The fixing method between the base plate 51 and the recovery chamber 1 ensures that the separation assembly 5 will not shift due to vibration during operation. Two vertical plates 52 are provided on the top of the base plate 51 to provide sliding guides for the internal connecting structure. The inner wall of the vertical plate 52 is provided with a sliding groove that matches the connecting structure, ensuring that the connecting structure can only slide in the horizontal direction. The vertical fixing structure between the vertical plate 52 and the base plate 51 forms the left and right support frames of the separation assembly 5, providing an installation base for the subsequent buffer structure. Two horizontal rails 53 are slidably connected inside each vertical plate 52, driving the connecting structure to achieve horizontal buffer sliding. A spring a54 is sleeved on the outside of each horizontal rail 53 to provide horizontal buffer force. A support frame 55 is provided on the outside of the horizontal rail 53 to support the internal structure and other components, forming the middle bearing layer of the separation assembly 5. Its fixing relationship with the horizontal rail 53 ensures that the support frame 55 moves synchronously when the horizontal rail 53 slides.

[0019] The support frame 55 has two vertical rails 56 internally slidingly connected, which drive the internal connecting structure to achieve vertical buffer sliding. The two vertical rails 56 are externally slidingly connected to a fixing block 58, which facilitates installation and protects the internal structure. A bidirectional motor is installed inside the fixing block 58. Two springs b57 are respectively sleeved on the outside of each vertical rail 56 to provide vertical buffer force. When the fixing block 58 is impacted and moves upward, the upper spring b57 is compressed and the lower spring b57 is stretched. The elastic reaction force pushes the fixing block 58 to reset, preventing the bearing of the rotating column 59 from being worn due to vertical vibration, and ensuring the stability of the centrifugal separation process. The fixing block 58 has two rotating columns 59 internally rotatably connected. By driving the bidirectional motor inside the fixing block 58, the external connecting structure is rotated to generate centrifugal force. Two centrifugal blocks 510 are respectively installed on the outside of each rotating column 59 to increase the centrifugal force during rotation. The centrifugal blocks 510 rotate at high speed with the rotating column 59. When the centrifugal blocks 510 rotate, they drive the connecting structure at the top of the centrifugal blocks 510 to separate the polyester fabric waste that is stuck together with glue in the recovery chamber 1.

[0020] A connecting plate 511 is provided on the top of the fixing block 58, connecting the bottom and top structures and transmitting the force of the bottom structure to the top structure. A top plate 512 is provided on the top of the connecting plate 511, which vibrates the structure inside the recycling chamber 1 to facilitate the separation of polyester waste. The fixing block 58 is externally slidably connected to the inside of the support frame 55 and externally slidably connected to the adjacent side of the two springs b57. When the fixing block 58 moves up and down during operation, it will directly squeeze and stretch the springs b57, causing the springs b57 to quickly generate buffer force, avoiding direct collision between the fixing block 58 and the frame of the support frame 55, and extending the service life of the component. The entire separation assembly 5 is fixedly connected to the recycling chamber 1. The recycling chamber 1 has a groove on the top plate 512, which facilitates the separation of the polyester fabric waste that is stuck together with glue in the recycling chamber 1 through the top connecting structure during vibration separation. At the same time, it also avoids the separation assembly 5 from generating force on the first crushing assembly 9 and the second crushing assembly 10 when vibrating.

[0021] The disassembly assembly 6 includes multiple bolts 61 distributed at the four corners of the bottom connecting structure. One end is screwed into a pre-set threaded hole on the inner wall of the recovery chamber 1, and the other end passes through the threaded hole of the bottom connecting structure. This facilitates the installation of the bottom connecting structure on the inner wall of the recovery chamber 1. The threaded connection method allows for quick disassembly, cleaning, and replacement of the internal connecting structure, improving maintenance efficiency. The external threads of the multiple bolts 61 are connected to the inside of the recovery chamber 1. The external threads of the multiple bolts 61 are connected to a U-shaped pressure plate 62. The pressure of the bolts 61 presses the internal connecting structure tightly onto the top plate 512. The threaded connection between the pressure plate and the bolts 61 ensures uniform pressure, preventing impurities from leaking into the lower part of the connecting structure due to insufficient local pressure. At the same time, the U-shaped structure avoids the material falling area of ​​the top plate 512, without affecting the separation assembly. For the feeding of part 5, a cloth 63 is provided at the bottom of the U-shaped pressure plate 62. It is glued to the bottom of the U-shaped pressure plate 62 to seal the gap between the U-shaped pressure plate 62 and the internal connecting structure. Because there are tiny gaps between the metal plates, the cloth 63 can fill the gaps to prevent fine polyester impurities from leaking into other areas of the recycling chamber 1. At the same time, the cloth 63 has a certain elasticity, which can buffer the pressure of the U-shaped pressure plate 62 on the internal connecting structure and prevent the connecting structure from being deformed. A separation plate 64 is provided inside the cloth 63. The cloth 63 wraps around the edge of the separation plate 64 to ensure that the edge gaps are sealed. The bottom of the separation plate 64 rests directly on the top plate 512 and is fixed by the pressure of the U-shaped pressure plate 62. After disassembly, the clogging impurities in the screen holes can be cleaned separately. The bottom of the separation plate 64 is located on the top of the top plate 512.

[0022] In the above embodiment, firstly, polyester waste enters the heating chamber 3 through the feed inlet 4 for preheating and softening, and is then introduced into the recycling chamber 1 through the conical feed inlet 2. After being crushed by the first crushing component 9, it passes onto the separating plate 64. The top plate 512 slides up and down along the vertical rail 56 inside the support frame 55 via the connecting plate 511 and the fixing block 58, compressing and stretching the spring b57 outside the vertical rail 56. The elastic reaction force of the spring b57 can absorb the vertical vibration impact force. The support frame 55 is slidably connected to the vertical plate 52 inside the recycling chamber 1 via the horizontal rail 53. The spring a54 outside the horizontal rail 53 will be compressed and stretched with the horizontal shaking of the support frame 55, further absorbing the horizontal vibration. At the same time, the entire separating component 5 and the recycling chamber 1 are fixedly connected. The recycling chamber 1 has a groove on the top plate 512 to facilitate the separation component 5. During vibration separation, the polyester waste in the recovery chamber 1 is separated by the separation plate 64. At the same time, it also avoids the influence of the separation component 5 on the first crushing component 9 and the second crushing component 10 when vibrating. Then, the bidirectional motor column 59 in the fixed block 58 drives the centrifugal block 510 to rotate at high speed to generate centrifugal force, which separates the polyester fabric waste that is stuck together with glue. The gap between the fabric 63 sealing plate 62 and the separation plate 64 prevents fine impurities from leaking in. Simply loosen the bolt 61 and remove the plate 62 to remove the fabric 63 and the separation plate 64. The impurities attached to the fabric 63 and the debris blocking the screen holes of the separation plate 64 can be cleaned to separate the composite polyester fabric waste that is stuck together with glue, which is convenient for subsequent crushing, ensuring crushing quality and ensuring continuous and stable operation of the device.

[0023] Example 2: Please refer to Figure 1 , Figure 5 and Figure 6This utility model provides a technical solution: a hot-melt recycling and processing device for waste polyester fabric. The first crushing component 9 includes a motor a91, which provides rotational power to the first crushing component 9. The motor a91 is located outside the recycling chamber 1 to prevent dust from entering the motor a91 and causing a short circuit, and also facilitates daily maintenance of the motor. The drive end of the motor a91 is provided with an electric shaft 92, which transmits the power of the motor a91 and drives the connecting structure to rotate. The electric shaft 92 is provided with a drive gear 93, which drives the meshing parts to rotate through gear meshing, realizing dual-shaft synchronous drive. The connection between the drive gear 93 and the electric shaft 92 ensures that the power transmission is slip-free. At the same time, the tooth width of the drive gear 93 matches the meshing parts to avoid tooth skipping during transmission. The electric shaft 92 is provided with a crusher 94, on which multiple high-speed crushers are evenly distributed. The steel blades, characterized by their sharpness and wear resistance, crush the falling polyester waste. They rotate at high speed with the electric shaft 92. A connecting rod 95 is rotatably connected inside the recovery chamber 1, and a crusher 94 is mounted externally on its side. When the cutter discs of the two crushers 94 rotate, the blades engage with each other, creating a shearing action that cuts large pieces of waste into smaller pieces. The cut pieces fall directly to the second crushing assembly 10 below. A driven gear 96 is installed externally on the connecting rod 95, transmitting the power of the driving gear 93 to the crusher 94 on the connecting rod 95, achieving synchronous rotation of the two crushing discs. When the driving gear 93 rotates, its teeth push the driven gear 96 to rotate in the opposite direction, driving the crusher 94 on the connecting rod 95 to form a counter-shearing action with the crusher 94 on the electric shaft 92, improving coarse crushing efficiency and preventing waste from accumulating between the cutter discs.

[0024] The external rotatable connection of the crusher 94 is connected to the inside of the recovery chamber 1, and the external drive gear 96 is meshed with the external drive gear 93.

[0025] The second crushing component 10 includes a motor b101, which provides power to the second crushing component 10. The motor b101 is externally connected to the outside of the recycling chamber 1. A protective cover is installed on the outside of the motor b101 to prevent collision with foreign objects. A connecting shaft 102 is provided at the drive end of the motor b101. A crusher 103 is provided outside the connecting shaft 102. The small pieces of waste coarsely crushed by the first crushing component 9 are finely crushed into even smaller particles. As the connecting shaft 102 rotates at high speed, the hard alloy teeth on the surface of the toothed roller squeeze and shear the falling small pieces of waste, crushing them into fine particles. The finely crushed particles pass through the toothed roller and the bottom of the recycling chamber 1 and are discharged from the discharge port 8. The crusher 103 is externally rotatably connected to the inside of the recycling chamber 1.

[0026] In the above embodiment, the starting motor a91 drives the electric shaft 92 to rotate, which in turn drives the active gear 93 and the driven gear 96 to mesh and transmit power. This causes the crusher 94 on the electric shaft 92 and the crusher 94 on the connecting rod 95 to rotate in opposite directions. By utilizing the shearing action of the high-speed steel blades and the comb teeth on the inner wall of the recycling chamber 1, large pieces of polyester waste are coarsely crushed into smaller pieces, solving the problem that large pieces of waste are prone to clogging when directly entering subsequent processes. Subsequently, the starting motor b101 drives the toothed roller of the crusher 103 to rotate at high speed through the connecting shaft 102. The hard alloy teeth on the surface of the toothed roller cooperate with the fixed tooth plate to perform secondary extrusion and shearing on the small pieces of waste after coarse crushing, refining them into even smaller particles. This ensures that the waste has a uniform shape. The coarse crushing process reduces the difficulty of processing large pieces of waste and avoids equipment blockage. The particle size after fine crushing is uniform, increasing the heat-receiving area of ​​the waste, shortening the heat melting time, and reducing energy consumption.
