Description

Technical Field

[0001] This invention relates to the field of wastewater and waste material separation, recycling, and filtration technology for polyester filament preparation, specifically a wastewater and waste material separation, recycling, and filtration process and equipment for polyester filament preparation. Background Technology

[0002] The production process of polyester filament (such as spinning, drawing, and winding) generates a large amount of industrial wastewater. In addition to containing chemical substances such as PTA residue and ethylene glycol, this wastewater also contains a large amount of filamentous fiber debris that has detached from the surface of the filament bundle. These fiber debris are soft, highly hydrophobic, difficult to degrade naturally, and have uneven length distribution, remaining suspended in the wastewater, which is one of the main challenges in solid-liquid separation.

[0003] Currently, the treatment of wastewater from polyester filament production generally employs filtration equipment for solid-liquid separation to trap solid impurities. Common filtration methods include single-layer metal screens and multi-media filters. However, existing filtration equipment has significant drawbacks when treating wastewater containing fiber debris: filamentous fiber debris easily entangles and accumulates on the mesh and surface of the filter disc as the wastewater flows. As filtration time increases, the fiber layer thickens, leading to a sharp reduction in the effective filtration area. This necessitates frequent shutdowns for manual cleaning or filter replacement, reducing work efficiency. Summary of the Invention

[0013] A wastewater and waste material separation, recovery, and filtration process for polyester filament preparation includes the following steps: S1. When separating and recycling wastewater and waste materials used in the preparation of polyester filament, the wastewater is added to the tank through the sewage pipe; S2. When wastewater enters the tank, start the motor to drive the rotating rod to rotate. When the rotating rod rotates, it drives the connecting sleeve to rotate, which in turn drives the winding rod to rotate. The winding rod then wraps around the fiber debris in the wastewater. S3. After passing through the winding device, the wastewater flows onto the filter disc. The filter disc filters the wastewater after winding. When the rotating rod rotates, it drives the fixed sleeve to rotate, which in turn drives the collection box and the shovel plate to rotate. The shovel plate then shovels the impurities on the filter disc into the collection box for collection. S4. After the wastewater passes through the filtration device, it will flow onto the conical shroud and enter the adsorption cylinder through the drain hole. The adsorption block can adsorb the wastewater, and the adsorbed wastewater will be discharged from the outlet pipe.

[0014] This invention provides a wastewater and waste material separation and recovery filtration process and equipment for polyester filament production. It has the following beneficial effects: 1. This invention, through the coordination of a motor, rotating rod, friction ring, connecting sleeve, and winding rod, enables the winding rod to collect and wind filamentous fiber debris, thus pre-treating wastewater and preventing a large amount of fiber debris from blocking the filter disc, resulting in poor filtration efficiency. Furthermore, by incorporating a copper rod, copper sheet, friction ring, and connecting spring, the copper sheet can rotate on the friction ring, which heats the copper sheet. This heat is then transferred to the copper rod, which in turn heats the winding rod, raising its temperature and softening the fiber debris. This allows the fiber debris to be more firmly wound onto the roller, preventing it from loosening and falling off.

[0015] 2. This invention, by setting up a fixed rod, filter disc, baffle, fixed sleeve, collection box, and shovel plate, uses the shovel plate to shovel impurities filtered by the filter disc into the collection box, preventing a large amount of impurities from adhering to the surface of the filter disc, thus blocking the filter disc and reducing filtration efficiency. Furthermore, by setting up a sliding sleeve, rotating block, spring plate, connecting rod, L-shaped pressure plate, and hemispherical ball, the L-shaped pressure plate can move downwards when the collection box rotates, compacting the impurities collected in the collection box, thus keeping the impurities tightly packed in the collection box and preventing them from being loose and easily discharged from the collection box, resulting in poor collection efficiency.

[0016] 3. This invention, by setting up an adsorption cylinder, adsorption block, conical cover, and drain hole, allows water to flow down from the filter plate onto the conical cover, which slows down the water flow. The water then flows through the drain hole into the adsorption cylinder and onto the adsorption block to adsorb wastewater. This prevents the wastewater from flowing too fast, which would prevent insufficient adsorption on the adsorption block and result in poor filtration. Furthermore, by incorporating a reciprocating thread, sliding rod, sealing plate, and guide block, the outlet pipe can drain intermittently, allowing the wastewater to remain in the adsorption cylinder for a longer period, ensuring thorough adsorption by the adsorption block and further improving the wastewater treatment effect.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-8 One embodiment of the present invention is: a wastewater and waste material separation and recycling filtration device for polyester filament preparation, comprising: a tank 1, a sealing door 2 hinged to the front of the tank 1, a sewage pipe 3 fixed to the top of the tank 1, and a water outlet pipe 4 fixed to the bottom of the tank 1, and further comprising: a winding device, the winding device being disposed inside the tank 1, the winding device being used to wind the sewage entering through the sewage pipe 3. The winding device includes: a motor 51, a rotating rod 52, a friction ring 53, a connecting sleeve 54, a winding rod 55, a copper rod 56, a copper sheet 57, and a connecting spring 58. The motor 51 is fixed to the top of the tank 1, and the rotating rod 52 is fixed to the output end of the motor 51. The friction ring 53 is fixed to the inner side of the tank 1. The connecting sleeve 54 is fixed to the outer wall of the rotating rod 52, and the winding rod 55 is fixed to the outer wall of the connecting sleeve 54. The winding rod 55 is used to collect fiber scraps. The copper rod 56 is attached to the inner side of the winding rod 55, and a copper sheet 57 is fixed to the end of the copper rod 56. The outer wall of the copper sheet 57 is in contact with the inner side of the friction ring 53. A copper rod 56 is provided to heat the winding rod 55. A stop is fixed on the outer wall of the winding rod 55. The stop restricts the position of the fiber debris on the outer wall of the winding rod 55, preventing the fiber debris from sliding to the copper sheet 57 and affecting the contact between the copper sheet 57 and the friction ring 53. A connecting spring 58 is fixed at the end of the winding rod 55. The side of the connecting spring 58 away from the winding rod 55 is fixed to the outer wall of the copper sheet 57. The connecting spring 58 is used to ensure that the copper sheet 57 is always pressed against the friction ring 53.

[0021] By setting up the motor 51, rotating rod 52, friction ring 53, connecting sleeve 54 and winding rod 55, the winding rod 55 can wind the filamentous fiber debris, collect the fiber debris, pre-treat the sewage, and prevent a large amount of fiber debris from easily blocking the filter disc 62, resulting in poor filtration efficiency of the filter disc 62. Furthermore, by setting up a copper rod 56, a copper sheet 57, a friction ring 53, and a connecting spring 58, the copper sheet 57 can rotate on the friction ring 53. The friction ring 53 can heat the copper sheet 57, and the heat is transferred to the copper rod 56, thereby heating the winding rod 55. This raises the temperature of the winding rod 55, which softens the fiber debris and makes it more tightly wrapped on the roller, preventing it from loosening and falling off.

[0022] In this embodiment, when sewage needs to be treated, the starting motor 51 can drive the rotating rod 52 to rotate, which in turn drives the connecting sleeve 54 to rotate, which in turn drives the winding rod 55 to rotate. Sewage is then added to the tank 1 through the sewage pipe 3. When the sewage enters the tank 1, it passes through the winding rod 55, which can wrap the long filamentous fibers in the sewage. When the winding rod 55 rotates, it can drive the copper sheet 57 to rotate on the friction ring 53. Due to friction, the copper sheet 57 can generate heat. When the copper sheet 57 generates heat, it can transfer the heat to the copper rod 56, which in turn transfers the temperature to the winding rod 55, causing the winding rod 55 to generate heat. This allows the winding rod 55 to heat the fiber debris on it, softening the fiber debris and making it more tightly wound onto the roller.

[0023] Please see Figures 1-8 Based on the above embodiments, in another embodiment of the present invention, a filter device is provided inside the tank 1 at the bottom of the winding device. The filter device is used to filter the sewage that has passed through the winding device. The filter device includes: a fixed rod 61, a filter disc 62, a baffle 63, a fixed sleeve 64, a collection box 65, a shovel 66, a sliding sleeve 67, a rotating block 68, a spring plate 69, a connecting rod 610, and an L-shaped pressure plate 611. The fixed rod 61 is fixed to the inner side of the tank 1. The filter disc 62 is fixed to the inner side of the tank 1. The baffle 63 is fixed to the top of the filter disc 62. The fixed sleeve 64 is fixed to the outer wall of the rotating rod 52. The collection box 65 is fixed to the outer wall of the fixed sleeve 64. The shovel 66 is fixed to the side wall of the collection box 65. The shovel 66 is used to shovel sewage impurities on the filter disc 62 into the collection box 65. The bottom of the collection box 65 has a filter hole for filtering sewage. For discharging sewage from the collection box 65, a sliding sleeve 67 passes through the top of the collection box 65. A rotating block 68 is fixed to the top of the sliding sleeve 67, and a hemisphere 612 is fixed to the top of the rotating block 68. A spring plate 69 is fixed to the bottom of the rotating block 68, and the bottom of the spring plate 69 is fixed to the top of the collection box 65. A connecting rod 610 passes through the sliding sleeve 67 and is slidably connected at the point of penetration. A return spring is fixed to the top of the connecting rod 610, and the bottom of the return spring is fixed to the top of the sliding sleeve 67. An L-shaped pressure plate 611 is fixed to the bottom of the connecting rod 610. The L-shaped pressure plate 611 is designed in an L-shape. When the L-shaped pressure plate 611 moves downward, the protruding part of the L-shaped pressure plate 611 can block the opening of the collection box 65, preventing impurities from being squeezed out of the opening when the L-shaped pressure plate 611 squeezes the contents of the collection box 65.

[0024] By setting a fixing rod 61, a filter disc 62, a baffle 63, a fixing sleeve 64, a collection box 65, and a shovel 66, the shovel 66 can shovel the impurities filtered by the filter disc 62 into the collection box 65, preventing a large amount of impurities from adhering to the surface of the filter disc 62, blocking the filter disc 62, and reducing the filtration efficiency. Furthermore, by setting up a sliding sleeve 67, a rotating block 68, a spring plate 69, a connecting rod 610, an L-shaped pressure plate 611, and a hemispherical ball 612, the L-shaped pressure plate 611 can move downward when the collection box 65 rotates, thereby compacting the impurities collected in the collection box 65, so that the impurities are tightly packed in the collection box 65, preventing the impurities from being loose and easily discharged from the collection box 65.

[0025] An adsorption device is installed at the bottom of the filter inside the tank 1. The adsorption device is used to adsorb and treat the sewage that has passed through the filter. The adsorption device includes: an adsorption cylinder 71, an adsorption block 72, a conical cover 73, a drain hole 74, a reciprocating thread 75, a slide rod 76, a sealing plate 77, and a guide block 78. The adsorption cylinder 71 is fixed inside the tank 1. The adsorption block 72 is detachably installed inside the adsorption cylinder 71. The conical cover 73 is detachably installed on the top of the adsorption cylinder 71. The drain hole 74 is opened on the conical cover 73. The conical cover 73 is used to slow down and buffer the sewage discharged from the filter. The side of the adsorption block 72 near the rotating rod 52 is in contact with the rotating rod 52. The bottom inner side of the rotating rod 52 is provided with a reciprocating thread 75. The slide rod 76 is installed in the internal thread of the reciprocating thread 75. The bottom of the slide rod 76 is fixed with a sealing plate 77. The bottom of the sealing plate 77 is fixed with a guide block 78. The guide block 78 is slidably installed inside the outlet pipe 4.

[0026] A wastewater and waste material separation, recovery, and filtration process for polyester filament preparation includes the following steps: S1. When separating and recycling wastewater and waste materials used in the preparation of polyester filament, the wastewater is added to tank 1 through sewage pipe 3; S2. When wastewater enters tank 1, start motor 51 to drive rotating rod 52 to rotate. When rotating rod 52 rotates, it drives connecting sleeve 54 to rotate, causing connecting sleeve 54 to drive winding rod 55 to rotate. Winding rod 55 winds the fiber debris in the wastewater. S3. After passing through the winding device, the wastewater flows onto the filter disc 62. The filter disc 62 filters the wastewater after winding. When the rotating rod 52 rotates, it drives the fixed sleeve 64 to rotate, which in turn drives the collection box 65 and the shovel plate 66 to rotate. The shovel plate 66 then shovels the impurities on the filter disc 62 into the collection box 65 for collection. S4. After the wastewater passes through the filtration device, it will flow onto the conical shroud 73 and enter the adsorption cylinder 71 through the drain hole 74. The adsorption block 72 can adsorb the wastewater, and the adsorbed wastewater will be discharged from the outlet pipe 4.

[0027] By setting up an adsorption cylinder 71, an adsorption block 72, a conical cover 73, and a drain hole 74, when water flows down from below the filter disc 62, the water flows onto the conical cover 73, which slows down the water flow. Then, the water flows into the adsorption cylinder 71 through the drain hole 74 and onto the adsorption block 72 to adsorb the sewage. This prevents the sewage from flowing too fast, which would prevent the sewage from being fully adsorbed and resulting in poor sewage filtration. By setting up the reciprocating thread 75, slide bar 76, sealing plate 77 and guide block 78, the outlet pipe 4 can drain water intermittently, which makes the sewage stay in the adsorption cylinder 71 for a longer time, so that the adsorption block 72 can fully adsorb the sewage, and further improve the sewage treatment effect.

[0028] In this embodiment, when wastewater passes through the winding rod 55, it flows onto the filter disc 62 for filtration. When the rotating rod 52 rotates, it drives the fixed sleeve 64 to rotate. When the fixed sleeve 64 rotates, it drives the collection box 65 to rotate, causing the shovel plate 66 to rotate against the top of the filter disc 62. This allows the shovel plate 66 to scoop impurities adhering to the top of the filter disc 62 into the collection box 65 for collection. When the collection box 65 rotates, it drives the rotating block 68 to rotate. When the rotating block 68 rotates the hemispherical ball 612 to contact the fixed rod 61... The rotating block 68 can compress the spring plate 69 when it moves downward, and when it moves downward, it can drive the sliding sleeve 67 to move downward. When the sliding sleeve 67 moves downward, it can drive the L-shaped pressure plate 611 to move downward. The L-shaped pressure plate 611 can squeeze and compact the impurities collected in the collection box 65. When the rotating block 612 rotates to a point where it no longer contacts the fixed rod 61, the spring plate 69 is in a compressed state, which can drive the rotating block 68 to move upward to reset. When wastewater passes through the filter disc 62, it flows onto the conical shroud 73. The conical shroud 73 buffers and slows the wastewater, which then enters the adsorption cylinder 71 through the drain hole 74. The wastewater then passes through the adsorption block 72, which adsorbs the wastewater, allowing it to be discharged from the outlet pipe 4, thus completing the filtration process. When the rotating rod 52 rotates, it drives the reciprocating thread 75 to rotate, causing the sliding rod 76 to move up and down within the thread. This causes the sliding rod 76 to move the sealing plate 77 back and forth within the outlet pipe 4. When the sealing plate 77 moves out from the top of the outlet pipe 4, the wastewater in the adsorption cylinder 71 is discharged from the outlet pipe 4. When the sliding rod 76 moves the sealing plate 77 into the outlet pipe 4, it seals the outlet pipe 4, allowing the wastewater in the adsorption cylinder 71 to remain within it. This intermittent drainage allows the wastewater to remain in the adsorption cylinder 71 for a longer period.
