Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment devices for non-woven fabric production, and in particular to comprehensive sewage treatment equipment for non-woven fabric masterbatch production. Background Art

[0002] During the non-woven fabric production process, polymers (such as polypropylene and polyester) are melt-spun to form primary fibers. If the spinning process causes fiber adhesion and breakage, the fibers may become bundles of varying lengths or string-like materials. Incompletely dispersed fiber clumps may remain in recycled or waste materials. After entering the production process, these fibers become impurities in wastewater and require treatment. However, existing fiber string filtration and treatment equipment still has the following defects during use:

[0003] For example, the Chinese patent publication number CN213698982U discloses a sewage treatment equipment for non-woven fabric processing, including a sewage treatment tank, the front and back sides of the bottom of the sewage treatment tank are fixedly connected to support legs, the top of the sewage treatment tank is connected to a sewage inlet, and both sides of the sewage inlet are fixedly connected to fixed bearings A, a rotating cross bar is transmission-connected between the two fixed bearings A, and water wheel blades are evenly spaced on the outside of the rotating cross bar. The right side of the rotating cross bar is meshed with a bevel gear B through a bevel gear A, and the bottom of the bevel gear B is fixedly connected to a rotating rod, and the outside of the rotating rod is sleeved with a fixed bearing B. A fixed bearing groove is provided on the top of the sewage treatment tank, and the inside of the fixed bearing groove is connected to the outside of the fixed bearing B. The bottom of the outside of the rotating rod is sleeved with a guide curved groove cylinder. The sewage treatment equipment for non-woven fabric processing prevents the non-woven fabric rope from clogging the filter plate and making it difficult to clean, thereby extending the service life of the filter plate.

[0004] Due to the different lengths of the fiber ropes, it is difficult to ensure the filtering effect of the fiber ropes through the above-mentioned device, resulting in uncertainty in the treatment degree, which makes it difficult to stably improve the sewage treatment efficiency and quality in the actual sewage treatment process; in addition, the fiber ropes after filtration treatment are difficult to remove from the filtration equipment, which also affects the normal use of the equipment. Summary of the Invention

[0010] Preferably, the entanglement cleaning mechanism further includes a removal mechanism; the removal mechanism is used to control the expansion degree of the airbag.

[0011] Preferably, the removal mechanism includes a cylinder, a piston and a driving mechanism; the cylinder is fixed to the winding rod, the piston is slidably connected to the cylinder, and the airbag and the interior of the cylinder are connected through a first vent hole; the driving mechanism is installed on the mounting plate and is used to drive the piston to move.

[0012] Preferably, the driving mechanism includes a cylinder, a limiting ring and a second limiting plate; the cylinder is mounted on the mounting plate, the output end of the cylinder is connected to the limiting ring, the second limiting plate is connected to the piston through a piston rod, and a ring groove is provided on the limiting ring, and the second limiting plate is slidably connected in the ring groove.

[0013] Preferably, the removal mechanism also includes multiple one-way valves and a nozzle; a second air vent is opened on the cylinder body, and the second air vent includes two branches, each of which is equipped with a one-way valve, and the interior of the cylinder body is connected to the nozzle through one of the branches; when negative pressure is generated in the airbag, the air in the cylinder body drives the one-way valve on one of the branches to open, so that air is ejected through the nozzle; when positive pressure is generated in the airbag, the air in the cylinder body drives the one-way valve on the other branch to open, so that air enters the cylinder body.

[0014] Preferably, an inlet and an outlet are respectively provided on the shell, and the output end of the dosing treatment mechanism is connected with the guide cover through the inlet; the sewage cleaned by the winding cleaning mechanism is discharged through the outlet.

[0017] Beneficial effects of the present invention:

[0018] By providing a second filtering and processing mechanism, the winding rod is driven to rotate, so that the fiber ropes flowing through can be wound around the winding rod. As the winding rods approach each other, the shorter fiber ropes can be rolled into balls, forming a self-winding fiber rope ball. This effectively captures fiber ropes of different lengths and separates them from the sewage by winding. The fiber ropes are clumped together by the second filtering and processing mechanism, making it easier to remove them later, reducing the problem of fiber ropes entangled in the filtering structure.

[0019] The anti-slip mechanism improves the stability of the fiber rope winding. The airbag contacts the fiber rope to prevent slipping, ensuring that the fiber rope can be reliably wound and captured, avoiding the degradation of the processing effect due to slipping, and further improving the equipment's processing capacity for fiber ropes. At the same time, the first limit plate can block most of the airbag to prevent excessive wear of the airbag.

[0020] By setting up a driving mechanism, the expansion or contraction of the airbag can be dynamically controlled. By controlling the expansion of the airbag, the winding effect of the fiber rope is ensured, and by controlling the contraction of the airbag, the fiber rope can be quickly removed, making the removal of the fiber rope convenient and efficient without affecting the normal use of the equipment, thereby improving the practicality and ease of operation of the equipment.

[0021] Through the design of the one-way valve and nozzle, the air flow and nozzle jet are automatically controlled according to the pressure changes in the airbag. When cleaning fiber ropes, the air sprayed from the nozzle can more thoroughly remove the residual fibers on the winding rod, improving the cleaning effect, further solving the problem of difficult removal of fiber ropes, and making equipment cleaning more convenient and efficient.

DETAILED DESCRIPTION

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0035] Example 1: Please refer to Figures 1-10 , a comprehensive treatment equipment for wastewater from non-woven masterbatch production, such as Figure 1-Figure 4 and Figure 7 As shown, it includes a first filtering and treating mechanism 1 and a dosing and treating mechanism 2; the non-woven masterbatch production wastewater comprehensive treatment equipment also includes a second filtering and treating mechanism 3; the second filtering and treating mechanism 3 includes: a guide cover 34 and a winding and cleaning mechanism 35; wherein, the guide cover 34 is tiltedly arranged in the shell 31; the winding and cleaning mechanism 35 includes a pair of mounting plates 351, two sets of turntables 352 and a motor 354; a pair of mounting plates 351 are arranged at the lead-out end of the guide cover 34, and each set of turntables 352 rotates around its axis and is connected to each mounting plate 351, and each turntable 352 is provided with a pair of winding rods 353; the motor 354 is installed on the mounting plate 351, and is used to drive the turntable 352 to rotate, so as to drive the winding rod 353 to rotate; when the winding rod 353 rotates, the winding rods 353 on the pair of mounting plates 351 continuously approach and / or move away from each other to wind the fiber rope.

[0036] It should be noted that, first, the guide hood 34 is installed at a specific angle within the housing 31, using gravity to scientifically guide the flow of sewage, creating an efficient and orderly flow path within the device. The symmetrically distributed winding rods 353 on the turntable 352 rotate synchronously under the precise drive of the motor 354. As the turntable 352 rotates, each pair of parallel winding rods 353 undergoes a cyclical motion, moving closer and farther away from each other. This ingenious design provides dual functions: as the winding rods 353 rotate, the fiber strands in the flowing sewage are automatically wrapped around the rod surfaces. Furthermore, when adjacent or opposing winding rods 353 approach each other, the shorter fiber strands between them gradually agglomerate under the squeeze and kneading action, forming a self-entwined fiber strand cluster. This dynamic processing mechanism captures fiber strands of varying lengths in all directions, efficiently separating both long filamentous fibers and shorter debris fibers from the sewage through entanglement and kneading. Compared to traditional filtration methods, this design significantly improves the targeted and effective treatment, ensuring stable sewage treatment efficiency and quality. At the same time, the aggregation of fiber ropes in the form of balls also provides great convenience for subsequent equipment cleaning and maintenance work, effectively reducing operation and maintenance costs and operational difficulty.

[0037] See also Figure 6-Figure 8 The winding cleaning mechanism 35 also includes a ring gear 355 and a gear 356; the winding rod 353 is connected to the turntable 352 around its axis; the gear 356 is coaxially fixed to the winding rod 353, the ring gear 355 is fixed to the mounting plate 351, and the ring gear 355 is meshed with the gear 356.

[0038] It should be noted that when the motor 354 drives the turntable 352 to rotate, the transmission system achieves a compound motion of the winding rod 353 through the precise meshing of the gear 356 and the ring gear 355. Specifically, the ring gear 355 is fixed to the inner wall of the housing 31. When the turntable 352 rotates, it drives the gear 356 mounted on its edge to orbit around the ring gear 355. Simultaneously, the meshing transmission of the gear 356 and the ring gear 355 causes the gear 356 to rotate, which in turn drives the connected winding rod 353 to rotate about its own axis. This compound motion significantly enhances the winding rod 353's ability to capture fiber ropes: the orbital motion expands the winding rod 353's range of action, allowing it to cover a larger area of ​​the sewage flow; the rotational motion generates a continuous tangential velocity on the surface of the winding rod 353, creating a speed difference with the fiber ropes in the sewage, thereby generating a stronger winding adhesion. Furthermore, the rotation of winding rod 353 evenly distributes the wound fiber clumps, avoiding dead corners caused by localized accumulation and further reducing the rate of missed fiber strands. This coordinated motion allows the device to more fully capture various fiber impurities in wastewater per unit time, effectively improving overall filtration quality and laying a solid foundation for subsequent advanced treatment steps.

[0039] See also Figure 6-Figure 8 The winding and cleaning mechanism 35 also includes an anti-slip mechanism 357; the anti-slip mechanism 357 includes an airbag 3571 and a first limiting plate 3572; the airbag 3571 is arranged on the winding rod 353, and multiple first limiting plates 3572 are respectively fixed on the four sides of the airbag 3571; the airbag 3571 and the multiple first limiting plates 3572 form a prism structure, and the edges of the prism structure are protruding to wrap the fiber rope.

[0040] It should be noted that when the winding rod 353 rotates, the edges of the prismatic structure formed by the airbag 3571 increase the contact area and friction with the fiber rope, preventing the fiber rope from slipping during the winding process, so that the fiber rope can be more firmly wound around the winding rod 353; the design of the anti-slip mechanism 357 improves the stability of the winding, ensures that the fiber rope can be reliably wrapped and captured, avoids the decline in processing effect due to slipping, and further improves the equipment's processing ability for the fiber rope.

[0041] See also Figure 6-Figure 9 The winding cleaning mechanism 35 also includes a removal mechanism 358; the removal mechanism 358 is used to control the degree of expansion of the airbag 3571; the removal mechanism 358 includes a cylinder 3581, a piston 3582 and a driving mechanism; the cylinder 3581 is fixed to the winding rod 353, the piston 3582 is slidably connected to the cylinder 3581, and the airbag 3571 and the cylinder 3581 are connected through the first vent 3586; the driving mechanism is installed on the mounting plate 351 and is used to drive the piston 3582 to move.

[0042] It should be noted that to optimize the winding and cleaning process of the fiber rope on the winding rod 353, the device utilizes a coordinated design of an airbag 3571 and a prismatic structure. This allows for functional switching by precisely controlling the expansion of the airbag 3571. During the winding process, gas is injected into the airbag 3571 to inflate it. The expansion force of the airbag 3571 acts on the flexible outer shell of the prismatic structure, significantly increasing the protrusion of the edges. This structural change provides the fiber rope with greater friction and stronger binding force during the winding process, effectively preventing the rope from slipping or loosening, and significantly improving the tightness and stability of the winding. During the cleaning phase, the gas in the airbag 3571 is exhausted, causing it to shrink. This reduces the protrusion of the prismatic edges, simultaneously reducing the contact area and friction between the fiber rope and the surface of the winding rod 353. At this point, the fiber rope can be easily peeled off the winding rod 353 with only a small amount of external force, significantly improving cleaning efficiency. Through the dynamic structural adjustment driven by the airbag 3571, the system can quickly and efficiently switch between the two working states of winding and cleaning, which not only ensures the winding quality but also reduces the difficulty of maintenance, providing reliable guarantee for the continuous operation of fiber processing equipment.

[0043] Specifically, the driving mechanism applies force to piston 3582, causing it to slide back and forth precisely within cylinder 3581. This movement causes changes in the air pressure within cylinder 3581. When piston 3582 slides in a specific direction, the air within cylinder 3581 is systematically transported to airbag 3571 through first vent 3586, causing airbag 3571 to expand, thereby increasing the protrusion of the edges of the prismatic structure and strengthening the winding effect on the fiber rope. Conversely, when piston 3582 slides in the opposite direction, the air within airbag 3571 flows back into cylinder 3581 through first vent 3586, causing airbag 3571 to contract, reducing the protrusion of the edges and weakening the friction and binding force between the fiber rope and the winding rod 353. This method of dynamically adjusting the expansion degree of the airbag 3571 through air pressure allows the fiber rope to be easily peeled off and removed after the filtration process is completed, simply by controlling the sliding direction and stroke of the piston 3582. The entire process does not require tedious manual operations, which not only avoids interference with the normal operation of the equipment, but also significantly improves the practicality of the equipment, greatly enhances the convenience and efficiency of operation, and provides a reliable solution for the optimization of the fiber processing process.

[0044] See also Figure 6-Figure 9 It can be understood that the present application does not limit the specific structure and installation method of the driving mechanism. The following only provides a feasible technical solution; the driving mechanism includes a cylinder 3583, a limiting ring 3584 and a second limiting plate 3585; the cylinder 3583 is installed on the mounting plate 351, the output end of the cylinder 3583 is connected to the limiting ring 3584, the second limiting plate 3585 is connected to the piston 3582 through the piston rod, and a ring groove is provided on the limiting ring 3584, and the second limiting plate 3585 is slidably connected in the ring groove.

[0045] It should be noted that to ensure stable sliding of the piston 3582 within the cylinder 3581 while ensuring uninterrupted operation of the motor 354 driving the winding rod 353, the device employs a unique transmission design. Specifically, the cylinder 3583 acts as the power source, outputting thrust to drive the displacement of the stop ring 3584. During this movement, the stop ring 3584 forms a linkage with the second stop plate 3585, driving the second stop plate 3585 to move synchronously. The second stop plate 3585 is tightly connected to the piston 3582, enabling the piston 3582 to slide stably back and forth within the cylinder 3581. The cooperation between the stop ring 3584 and the second stop plate 3585 plays a key role in this transmission process. While ensuring effective drive of the piston 3582, they also establish an independent transmission path, allowing the motor 354 to continuously and stably drive the winding rod 353 without being affected by the movement of the piston 3582. This allows two different motion modes to operate in parallel, ensuring efficient and stable operation of the entire mechanical system.

[0046] Example 2: This example differs from Example 1 in that: Figure 9-10 The removal mechanism 358 also includes a plurality of one-way valves 3588 and a nozzle 3589; a second vent hole 3587 is opened on the cylinder body 3581, and the second vent hole 3587 includes two branches, each of which is equipped with a one-way valve 3588, and the interior of the cylinder body 3581 is connected to the nozzle 3589 through one of the branches; when negative pressure is generated in the airbag 3571, the air in the cylinder body 3581 drives the one-way valve 3588 on one of the branches to open, so that the air is ejected through the nozzle 3589; when positive pressure is generated in the airbag 3571, the air in the cylinder body 3581 drives the one-way valve 3588 on the other branch to open, so that air enters the cylinder body 3581.

[0047] It should be noted that when negative pressure is generated in the airbag 3571, the airbag 3571 itself contracts, and the air pressure in the cylinder 3581 is greater than the pressure in the airbag 3571, driving the one-way valve 3588 on the branch connected to the nozzle 3589 to open, and air is ejected through the nozzle 3589. The ejection direction of the nozzle 3589 is parallel to the length direction of the first limit plate 3572, and can be used to blow off the fiber rope on the winding rod 353; when positive pressure is generated in the airbag 3571, the air pressure in the cylinder 3581 is less than the pressure in the airbag 3571, driving the one-way valve 3588 on the other branch to open, and air enters the cylinder 3581 to balance the air pressure in the cylinder.

[0048] See also Figure 1-Figure 3 The shell 31 is provided with an inlet 32 ​​and an outlet 33 , respectively. The output end of the dosing treatment mechanism 2 is connected with the guide cover 34 through the inlet 32 ​​; the sewage cleaned by the winding cleaning mechanism 35 is discharged through the outlet 33 .

[0049] It should be noted that, after the sewage is first treated by the dosing treatment mechanism 2, it enters the shell 31 of the second filtering treatment mechanism 3 from the inlet 32, and flows to the winding and cleaning mechanism 35 under the guidance of the guide cover 34. After the fiber rope is wound and cleaned, the purified sewage is discharged from the outlet 33, forming a complete sewage filtration treatment process; the setting of the inlet 32 ​​and the outlet 33 ensures the orderly flow of sewage in the equipment, so that the dosing treatment mechanism 2 and the second filtering treatment mechanism 3 can be smoothly connected, ensuring the continuity and smoothness of the sewage treatment process, which helps to improve the overall sewage treatment efficiency. At the same time, the reasonable flow direction design also facilitates the installation and maintenance of the equipment.

[0050] See also Figure 1-Figure 3The first filtering treatment mechanism 1 includes a stirring mechanism and a filter screen; the stirring mechanism and the filter screen are both installed in the shell 31; the stirring mechanism is used to continuously stir the sewage before filtering through the filter screen; the dosing treatment mechanism 2 includes a doser and a drum filter; the doser and the drum filter are both installed in the shell 31; the doser is used to flocculate the sewage, and the drum filter is used to dynamically filter the flocculated sewage.

[0051] It should be noted that the setting of the stirring mechanism improves the state of the sewage before filtration, makes the filtration more uniform and efficient, reduces the clogging of the filter mesh by large particles of impurities or aggregated fiber ropes, extends the service life of the filter mesh, and at the same time improves the quality of the initial filtration, providing better conditions for subsequent dosing treatment and secondary filtration treatment, which helps to stabilize the efficiency and quality of the overall sewage treatment; the flocculation treatment of the dosing device can effectively remove fine impurities in the sewage and improve the degree of sewage purification; the dynamic filtration design of the drum filter reduces the risk of clogging while ensuring the filtration effect, so that the sewage after dosing treatment can smoothly enter the subsequent treatment link, thereby improving the efficiency and stability of the entire sewage treatment process.
