Description

Technical Field

[0001] This invention relates to the field of yarn dyeing wastewater treatment technology, and in particular to a treatment device for yarn dyeing wastewater. Background Technology

[0002] Yarn dyeing is an important process in the textile industry. The wastewater it produces is complex, containing a large amount of fiber debris, unfixed dyes (such as reactive, disperse and other difficult-to-degrade organic pigments), chemical auxiliaries and high concentrations of salt.

[0003] Traditional treatment methods often employ a combined process of "physicochemical pretreatment - biochemical treatment," which, while effective to some extent, has significant drawbacks: First, the filtration units in the pretreatment stage are easily clogged by long fiber impurities such as yarn and yarn ends, requiring frequent shutdowns for cleaning and affecting the continuity of treatment; second, physical, chemical, and biological treatment units are often independent, resulting in large equipment footprints, long process flows, and cumbersome replacement and maintenance of treatment modules (such as packing materials and catalysts); third, it is difficult to achieve coordinated and flexible control of "solid-liquid separation - biodegradation - chemical oxidation - deep purification" within a compact space, and it is not highly adaptable to dyeing wastewater with varying compositions. Therefore, there is an urgent need to develop a highly integrated and automated yarn dyeing wastewater treatment device that can effectively intercept solid impurities, flexibly combine multi-stage treatment processes, and possess online self-cleaning capabilities. We propose a treatment device for yarn dyeing wastewater. Summary of the Invention

[0004] In order to overcome the technical problems existing in the prior art, the present invention provides a device for treating yarn dyeing wastewater.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: including a processing pool, with an inlet pipe and an outlet pipe respectively arranged on both sides of the processing pool, a driving component arranged at the center of the processing pool, a processing component arranged on the side of the driving component, and auxiliary components arranged on the sides of the processing pool and the driving component. The drive assembly includes a main motor, and a connecting shaft and a mating tube are provided on the side of the main motor. The connecting shaft and the mating tube are provided with mating grooves and slots on their sides. The processing assembly includes a filter belt, with mounting frames symmetrically arranged on both sides of the filter belt. The filter belt contains processing components, a mating rod, and a shaft roller. The shaft roller has a timing belt, a mating gear, and a mating toothed ring on its side. The mounting frames have a constraint frame, a constraint block, and a locking rod on their sides. The auxiliary component includes a cleaning shaft, a guide plate on the side of the cleaning shaft, a fixed frame fixedly connected to the upper side of the guide plate, a connecting pipe on the upper side of the fixed frame, and nozzles equidistantly arranged on the lower side of the guide plate.

[0006] Furthermore, the main motor is fixedly installed on the side of the treatment tank, the connecting shaft is fixedly installed at the output end of the main motor and extends through the treatment tank, the mating grooves are equidistantly opened on the side of the connecting shaft, the mating tube is movably installed inside the connecting shaft and the mating tube is fixedly installed on the side of the treatment tank by a bracket, the slot is opened on the upper side of the mating tube, and the slot corresponds to the mating groove position above the connecting shaft.

[0007] Furthermore, the filter belts are equidistantly arranged on the side of the connecting shaft, and filter holes are equidistantly opened on the side of the filter belts. The positioning blocks are symmetrically fixedly installed on the side of the mounting frame and are snapped into the side of the processing component. The two ends of the mating rod extend through the mounting frame, and the shaft roller is limited and sleeved on the side of the mating rod and is in contact with the inner side of the filter belt.

[0008] Furthermore, the synchronous belt is symmetrically splined and sleeved on the sides of the two sets of mating rods, and the synchronous belt is attached to the side of the mounting frame away from the filter belt. The mating gear is threaded and sleeved on the side of the mating rod. The mating gear ring is engaged on the side of the mating gear and is fixedly installed on both sides inside the treatment tank. The mating gear ring is a four-fifths circular ring with teeth on the outside and the opening of the mating gear ring faces upward.

[0009] Furthermore, the mounting bracket has symmetrical alignment grooves on its side, the constraint bracket is fixedly installed on the side of the connecting shaft and slidably disposed inside the alignment groove, the constraint block is fitted to the side of the constraint bracket and the mounting bracket, and the locking rod is threaded through and installed between the constraint bracket and the constraint block.

[0010] Furthermore, the cleaning shaft is disposed on the side of the connecting shaft and is attached to the side of the corresponding two sets of filter belts. A fixing rod is movably disposed inside the cleaning shaft, and fixing blocks are symmetrically fixedly installed on both sides of the fixing rod, with the fixing blocks fixedly installed on the side of the connecting shaft. Furthermore, a damping block is movably sleeved on the side of the fixing rod, and the damping block is fixedly installed on the side of the fixing block and fits against the cleaning shaft. The damping block is a ring block made of elastic and wear-resistant material.

[0011] Furthermore, the guide plate is positioned on the upper side of the processing pool corresponding to the slotted position, the fixing bracket screws are fixedly positioned on the upper side of the processing pool, and the connecting pipe extends through the inside of the guide plate.

[0012] Compared with the prior art, the beneficial effects that this invention can achieve are: 1. This invention achieves a highly efficient, continuous, and easy-to-maintain yarn dyeing wastewater treatment device by setting up a driving component, a processing component, and an auxiliary component. The core of this invention is to integrate dynamic filtration, multi-stage treatment modules, and automatic cleaning and sewage discharge functions into one integrated system. It combines continuous filtration with multi-stage treatment and can perform online self-cleaning during the circulation process. In addition, the modular design of the treatment components allows for selective adaptation and solves the problems of equipment separation, easy clogging, and complex operation in traditional processes.

[0013] 2. This invention, by setting up a driving component and a treatment component, drives a circumferentially distributed filter belt to rotate. During the movement, it continuously performs physical interception of solid impurities such as yarn ends and fiber scraps in the wastewater. At the same time, biological packing materials, catalyst carriers, or adsorbents can be flexibly installed on the inner side of the filter belt as needed. As the wastewater passes through the filter holes and comes into contact with these components, it can undergo biodegradation, chemical oxidation, and physical adsorption reactions sequentially or synergistically. This integrates solid-liquid separation with multiple deep purification processes into a single rotating cycle, shortening the treatment process and reducing the equipment's footprint.

[0014] 3. This invention, through the setting of a processing component, ensures that when the filter belt rotates to the top, its drive gear disengages from the fixed gear ring. At this time, the auxiliary component automatically starts, spraying treatment liquid or clean water onto the filter belt through the nozzle. The rinsing water not only directly cleans the surface of the filter belt but also impacts the cleaning shaft, causing it to rotate actively and driving the filter belt to move in the opposite direction, achieving a thorough rinsing of the entire working surface of the filter belt. The impurities washed off are quickly collected with the wastewater and automatically discharged the moment the mating groove at the top aligns with the fixed drain pipe. This effectively avoids filter hole clogging, ensures continuous and stable processing capacity, and reduces the burden of manual cleaning.

[0015] 4. This invention, by setting up a constraint frame and locking rod and its surrounding components, uses a snap-fit ​​installation for the treatment components, which are fixed by the detachable constraint frame and locking rod. When it is necessary to change or adjust the treatment process (such as replacing the biological packing plate with an activated carbon plate), only a few fasteners need to be removed to take out the entire filter belt and mounting frame unit, and the internal treatment components can be easily replaced. The modular design allows the device to quickly adapt to yarn dyeing wastewater with different water quality characteristics, or to upgrade the treatment level according to the discharge standards, which significantly improves the versatility and maintainability of the equipment.

[0016] 5. By setting up a drive component, the filter belt driving, cleaning and sewage discharge functions of the entire device are driven by a single motor. The working mode is naturally switched by the change of gear and gear ring meshing state (the lower processing section is actively driven and the upper cleaning section is passively cleaned). The pure mechanical linkage does not require additional independent drive or complex electrical control, which reduces energy consumption and failure rate, and realizes the cyclic operation of processes from processing to cleaning to sewage discharge.

[0017] 6. The present invention allows for multi-stage agitation of wastewater through the rotatable movement of the connecting shaft, filter belt, and cleaning shaft. This enables more effective mixing and reaction of wastewater and treatment liquid, and the agitated wastewater also impacts the filter belt, reducing the likelihood of filter block clogging during use.

[0020] To make the technical means, creative features, and achieved objectives and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0021] Example: Figures 1 to 3 As shown, a treatment device for yarn dyeing wastewater includes a treatment tank 1, which is a rectangular tank with a hollowed-out upper side and an arc-shaped bottom. An inlet pipe 11 and an outlet pipe 12 are fixedly installed through both sides of the treatment tank 1, respectively. Wastewater is transported through the inlet pipe 11 and discharged through the outlet pipe 12 after treatment. A drive component 2 is set at the center of the treatment tank 1. The drive component 2 can drive the whole system and discharge wastewater. A treatment component 3 is set on the side of the drive component 2. The treatment component 3 can circulate and filter solid impurities such as yarn and yarn ends in the wastewater and make the wastewater undergo multi-stage purification treatment in the circulation. An auxiliary component 4 is set on the side of the treatment tank 1 and the drive component 2. The auxiliary component 4 can add treatment liquid (which can be a pH adjuster, decolorizing agent, microbial agent and oxidant, which can be selected and supplied according to needs) and clean the treatment component 3.

[0022] like Figure 2 , Figure 4 and Figure 5 As shown, the drive assembly 2 includes a main motor 21, which is fixedly mounted on the side of the processing tank 1. A connecting shaft 22 is fixedly mounted on the output end of the main motor 21 and extends through the processing tank 1. The main motor 21 can drive the connecting shaft 22 to rotate inside the processing tank 1. The side of the connecting shaft 22 away from the main motor 21 is hollow. A circular array of equally spaced mating grooves 23 extending into the inner side of the connecting shaft 22 are provided on its side. The mating grooves 23 are rectangular grooves. The internal movable part is equipped with a matching pipe 24, which is fixed to the side of the treatment tank 1 by a bracket and remains stationary. The matching pipe 24 is a circular pipe, and a slot 25 is opened through it on the upper side. The slot 25 corresponds to a set of matching slots 23 above the connecting shaft 22. The slot 25 is a rectangular slot. The other end of the matching pipe 24 is connected to the waste liquid processor. Specifically, when the main motor 21 drives the connecting shaft 22 to rotate, the matching slot 23 on it will periodically align with the slot 25 on the fixed matching pipe 24. When the two are aligned, the liquid located in the upper part of the device and the impurities that have been cleaned can flow into the matching pipe 24 through the matching slot 23 and the slot 25, and finally be discharged to the waste liquid treatment module.

[0023] like Figure 2 , Figure 4 and Figures 6 to 9As shown, the treatment component 3 includes a filter belt 31, which is circumferentially arrayed and equidistantly arranged on the side of the connecting shaft 22. The filter belt 31 is an "O"-shaped belt, and filter holes 311, which are circular holes, are equidistantly opened on the side of the filter belt 31. Mounting frames 32 are symmetrically arranged on both sides of the filter belt 31. The mounting frames 32 are rectangular plates with arc-shaped sides. A treatment component 33 is attached to the center of the inner side of the filter belt 31. The treatment component 33 can be selected and combined according to the needs of the treatment stage. For example, it can be an elastic packing plate for biofilm formation, a catalyst carrier plate for catalytic oxidation reaction, or an activated carbon plate for adsorption and decolorization. Through the cyclic rotation of the filter belt 31, the wastewater can come into contact with different functional treatment modules in sequence to achieve initial treatment. The filter belt 31 undergoes a composite treatment involving step oxidation (biodegradation), advanced oxidation (chemical oxidation), and deep filtration (physical adsorption). A mounting frame 32 is symmetrically fixed to the side of the treatment component 33, with positioning blocks 321 engaging with the side of the treatment component 33. The positioning blocks 321 are cylindrical blocks. Symmetrically arranged mating rods 34 are positioned on both sides inside the filter belt 31, extending through the mounting frame 32 at both ends. Each mating rod 34 is a cylindrical rod with threads and spline grooves at both ends and a boss at its center. A cylindrical roller 35 is fitted to the side of the mating rod 34, fitting against the inner side of the filter belt 31. A synchronous belt 351 is symmetrically splined onto the sides of the two sets of mating rods 34, and the belts are synchronized... The timing belt 351 is attached to the side of the mounting bracket 32 ​​away from the filter belt 31. The timing belt 351 is an "O"-shaped belt with an inner spline. A matching gear 36 is threaded onto the side of the matching rod 34. The matching gear 36 is a circular ring gear with an inner thread. A matching toothed ring 37 is meshed on the side of the matching gear 36 and is fixedly installed on both sides inside the treatment tank 1. The matching toothed ring 37 is a four-fifths circular ring with teeth on the outer side and the opening of the matching toothed ring 37 faces upward. Specifically, when the connecting shaft 22 is driven to rotate counterclockwise, the entire filter belt 31 rotates synchronously. At this time, the matching gear 36 meshes with the matching toothed ring 37. The matching gear 36 drives the matching rod 34 to rotate, and the matching rod 34 drives the shaft roller 3. 5. Rotating counterclockwise, the shaft roller 35 supports and drives the filter belt 31 to rotate counterclockwise. The synchronous belt 351 makes the corresponding shaft roller 35 rotate synchronously, ensuring the stable rotation of the filter belt 31. The rotation of the filter belt 31 allows impurities to be filtered from the sewage through the filter holes 311. The sewage is stirred and works with the treatment component 33 to complete multi-stage treatment of the sewage, including intercepting suspended impurities, degrading organic matter and dyes through biological or chemical action, and adsorbing and removing soluble pigments. In addition, after removing the filter belt 31 as a whole and unscrewing the mating gear 36, the synchronous belt 351 and the mounting bracket 32 ​​can be removed in sequence. This allows the treatment component 33 to be replaced, and different materials of treatment components 33 can be installed for use as needed. The mounting bracket 32 ​​has symmetrically arranged alignment grooves 38 on its side. The alignment grooves 38 are rectangular grooves. A constraint bracket 39 is fixedly installed on the side of the connecting shaft 22 corresponding to the alignment grooves 38 and is slidably disposed inside the alignment grooves 38. The constraint bracket 39 is a "U"-shaped bracket. A constraint block 391 is provided on the side of the constraint bracket 39 away from the connecting shaft 22 and fits against the side of the mounting bracket 32. A locking rod 392 is symmetrically threaded between the constraint bracket 39 and the constraint block 391. The locking rod 392 is a "T"-shaped cylindrical threaded rod. The constraint bracket 39 and the constraint block 391 are threadedly locked together to form a whole by the locking rod 392. The constraint bracket 39 and the constraint block 391 can constrain and stabilize the mounting bracket 32 ​​as a whole. Conversely, after removing the constraint block 391, the mounting bracket 32 ​​can be quickly disassembled and installed.

[0024] like Figure 2 , Figure 4 and Figures 9 to 11 As shown, the auxiliary component 4 includes a cleaning shaft 41, which is located on the side of the connecting shaft 22 and is attached to the side of the corresponding two sets of filter belts 31. The cleaning shaft 41 is a cylindrical roller with a sawtooth cross-section and its side is convex and inclined. A fixing rod 42 is movably installed inside the cleaning shaft 41. The fixing rod 42 is a cylindrical rod. Fixing blocks 43 are symmetrically fixed on both sides of the fixing rod 42 and are fixedly installed on the side of the connecting shaft 22. A damping block 44 is movably sleeved on the side of the fixing rod 42 and is fixedly installed on the side of the fixing block 43 and attached to the cleaning shaft 41. The damping block 44 is a ring block made of elastic and wear-resistant material. Specifically, when the cooperating gear 36 meshes with the cooperating gear ring 37, the filter belt 31 is driven to rotate counterclockwise, and the cleaning shaft 41 is passively driven to rotate by the filter belt 31, which can assist in agitating the sewage. A guide plate 45 is provided on the upper side of the treatment tank 1 corresponding to the slot 25. The guide plate 45 is a hollow rectangular plate. A fixing frame 46 is fixedly connected to the upper side of the guide plate 45 and screwed to the upper side of the treatment tank 1. The fixing frame 46 is an I-shaped frame. A connecting pipe 47 is provided on the upper side of the fixing frame 46 and extends into the interior of the guide plate 45. The connecting pipe 47 is connected to the liquid supply module. Spray nozzles 48 are arranged equidistantly and in multiple directions on the lower side of the guide plate 45. The connecting pipe 47 transports the treatment liquid to the... Inside the guide plate 45, the treatment liquid is sprayed in multiple directions through the nozzle 48 to wash the side of the corresponding filter belt 31, causing the yarn ends and impurities filtered on the side to flow into the uppermost mating groove 23. The synchronous water flow causes the cleaning shaft 41 to rotate actively. At this time, the side of the corresponding mating gear 36 and the disengaged mating gear ring 37 are rotated by the cleaning shaft 41. The side of the filter belt 31 is cleaned by the treatment liquid. The waste liquid carrying impurities flows from the slot 25 into the mating pipe 24 and is discharged to the waste liquid treatment module.

[0025] Working principle: Module replacement and preparation: After unscrewing the locking rod 392, remove the constraint block 391. At this time, the mounting bracket 32 ​​can be pulled out from the side of the constraint bracket 39. The mounting bracket 32 ​​and the filter belt 31 can be disassembled as a whole. Then, after unscrewing the mating gear 36, the synchronous belt 351 can be disengaged from the side of the mating rod 34. The mounting bracket 32 ​​is removed and detached from the filter belt 31. The positioning block 321 loses its positioning constraint on the processing component 33. At this time, different processing components 33 (elastic packing plate, catalyst plate and activated carbon plate) can be replaced as needed. Similarly, the reverse operation can be used for assembly and installation. The mounting bracket 32 ​​and the filter belt 31 are fixed by the combined constraint of the constraint block 391 and the constraint bracket 39. The mating gear 36 and the mating gear ring 37 are kept in a meshing state. Wastewater is supplied and then circulated for multi-stage treatment: Wastewater is transported into the treatment tank 1 through the inlet pipe 11. The main motor 21 drives the connecting shaft 22 to rotate counterclockwise. The connecting shaft 22 drives the mounting frame 32 and the filter belt 31 to rotate and agitate the wastewater. At the same time, the gear 36 meshes with the gear ring 37. The gear 36 drives the shaft roller 35 to rotate counterclockwise through the synchronous belt 351 via the connecting rod 34. The shaft roller 35 drives the filter belt 31 to rotate in a cycle supported by the shaft roller 35. The filter belt 31 can further agitate the wastewater. Impurities such as yarn ends and yarns in the wastewater are filtered through the filter holes 311. The filtered wastewater comes into contact with the treatment components 33 from inside the filter belt 31, completing the multi-stage treatment of the wastewater, including intercepting suspended impurities, degrading organic matter and dyes through biological or chemical action, and adsorbing and removing soluble pigments. After the wastewater is purified, it is discharged from the outlet pipe 12. When the filter belt 31 rotates counterclockwise, it can drive the cleaning shaft 41 to rotate passively, which helps to agitate the sewage. The cleaning shaft 41 can move the impurities on the side of the filter belt 31 to accumulate inside the corresponding matching tank 23 for storage. When the matching tank 23 corresponds to the slot 25, the stored impurities can flow into the matching pipe 24 and be discharged to the waste liquid treatment device. Waste cleaning and recycling: As the connecting shaft 22 drives the filter belt 31 to rotate, when the filter belt 31 and the mounting frame 32 as a whole are in the upper position, the mating gear 36 and the mating toothed ring 37 disengage. The fixed frame 46 conveys the treatment liquid into the guide plate 45, and the nozzle 48 sprays the treatment liquid in multiple directions. The treatment liquid can wash the side of the filter belt 31, washing the impurities on its side to the cleaning shaft 41. Then, the flowing treatment liquid can impact the cleaning shaft 41 to rotate actively. The cleaning shaft 41 drives the corresponding filter belt 31 to rotate in a coordinated cycle. The cleaning shaft 41 can perform a complete side cleaning operation on the filter belt 31, so that the waste liquid with impurities flows through the mating tank 23 and the slot 25 to the mating pipe 24, and finally flows to the waste liquid treatment device for centralized treatment. After cleaning, the filter belt 31 is driven to rotate by the connecting shaft 22. At this time, the gear 36 and the gear ring 37 are engaged, and the filter belt 31 and the treatment component 33 can circulate to purify the sewage.
