Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and more specifically, to a textile wastewater treatment device. Background Technology

[0002] Currently, the traditional process for treating textile wastewater generally involves the following steps: First, large particulate impurities such as fiber debris are removed through screening and grating. Then, the pH value of the wastewater is adjusted by neutralization. In the core treatment stage, organic pollutants and suspended solids are degraded through coagulation and sedimentation combined with biological treatment (such as activated sludge or biofilm processes). For recalcitrant dyes, advanced oxidation technologies (such as ozone oxidation) are used for decolorization and decomposition. Finally, residual pollutants are further treated through activated carbon adsorption or membrane separation technology, and the wastewater is disinfected to achieve compliant discharge or reuse.

[0003] In coagulation and sedimentation treatment, coagulation and sedimentation devices are needed to separate and filter impurities in wastewater. These devices primarily achieve sedimentation by adding coagulants and flocculants to the wastewater. Therefore, the effectiveness of coagulant and flocculant addition directly impacts wastewater treatment efficiency. Existing coagulation and sedimentation devices often employ flow-type automatic dosing systems, but these systems suffer from two major technical challenges in actual operation: First, the dynamic water flow environment impairs the accuracy of agent dosing. While precise control can be achieved through integrated online flow rate and volume monitoring systems, the high costs of sensor maintenance and system upgrades limit the feasibility of upgrading existing treatment facilities. Second, the uniformity of mixing between agents and wastewater is constrained by fluid dynamics. Even with mechanical stirring devices, mixing efficiency fluctuates due to turbulent water flow, leading to localized reagent concentration gradients and affecting the sufficiency of flocculation. Therefore, a new treatment device is urgently needed that combines low-cost adaptability, dynamic compensation for dosing accuracy, and enhanced hydraulic mixing. Summary of the Invention

[0004] The purpose of this invention is to provide a textile wastewater treatment device to solve the aforementioned technical problems.

[0005] The present invention solves the above-mentioned technical problems through the following technical solutions:

[0006] This invention provides a textile wastewater treatment device, comprising: a treatment tank body, a stirring mechanism, and a treatment agent addition mechanism;

[0007] The treatment agent addition mechanism is installed at one end of the water inlet of the treatment tank body. The treatment agent addition mechanism includes an inlet cylinder, an inlet pipe, a treatment agent delivery pipe, a rotating drum, a rotation drive assembly, a stirring assembly, and several partition plates. The inlet cylinder is detachably installed on one side of the treatment tank body. The inlet pipe and the treatment agent delivery pipe are both connected to the outside of the inlet cylinder. The bottom of the inlet cylinder is provided with a drain port facing the side of the treatment tank body. The rotating drum is coaxially rotatably installed on the inside of the inlet cylinder.

[0008] Several partition plates are evenly slidably installed along the outer circumference of the rotating cylinder, and the end of several partition plates away from the rotating cylinder slides against the inner wall of the liquid inlet cylinder. A pretreatment chamber for temporary storage of a certain amount of wastewater is formed between every two partition plates.

[0009] The rotary drive assembly is connected to one end of the rotating drum for transmission. The rotary drive assembly drives the rotating drum to rotate within the liquid inlet cylinder. The agitator assembly is installed on the rotating drum and agitates the wastewater stored in each pretreatment chamber.

[0010] As a further optimization of the present invention, the agitation assembly includes a rotating drive component and agitation blades of the same number as the partition plates. The rotating drive component is disposed inside the rotating drum, and a plurality of agitation blades are uniformly rotated and installed along the outer circumference of the rotating drum. Each agitation blade is located between two adjacent partition plates. The rotating drive component is connected to the plurality of agitation blades in a transmission manner, and the rotating drive component drives the plurality of agitation blades to rotate synchronously with the rotating drum.

[0011] As a further optimization of the present invention, the rotating drive includes a fixed gear and a transmission part with the same number as the stirring blades. The axis of the fixed gear coincides with the axis of the rotating drum, and one side of the fixed gear is fixed to the liquid inlet cylinder. A plurality of transmission parts are evenly distributed around the outside of the fixed gear. The transmission part includes a transmission gear and two bevel gears. The transmission gear meshes with the outside of the fixed gear. One bevel gear is fixed to one side of the corresponding transmission gear, and the other bevel gear is fixed to the rotating end of the stirring blade, and the two bevel gears mesh.

[0012] As a further optimization of the present invention, the fixed gear is an incomplete gear with a non-meshing section, and the non-meshing section of the incomplete gear corresponds to the position of the liquid inlet pipe.

[0013] As a further optimization of the present invention, the liquid inlet cylinder is provided with a contraction drive assembly for driving the partition plate to contract towards the inside of the rotating cylinder. The contraction drive assembly includes a track plate and a number of sliding wheels and return springs equal to the number of partition plates. The track plate is fixedly installed on the inside of the liquid inlet cylinder. A traction groove is provided on one side of the track plate. The sliding wheels are all in rolling connection with the traction groove. The traction groove is composed of a first arc groove coaxial with the rotating cylinder and a second arc groove with its center facing the inside of the liquid inlet cylinder. The second arc groove is located near the drain port. The inside of the rotating cylinder is provided with a movable groove corresponding to the partition plate. One end of the sliding wheels slides through the corresponding movable groove and is fixed to one side of the corresponding partition plate. One end of the return springs is fixed to one side of each sliding wheel, while the other end of the return springs is fixed to the inside of the corresponding movable groove.

[0014] As a further optimization of the present invention, the partition plate is composed of a rectangular plate and a plurality of sealing strips. The plurality of sealing strips are fixedly installed on the side of the rectangular plate that contacts the inner side of the liquid inlet cylinder. The sealing strips are used to seal the gap between the rectangular plate and the inner side of the liquid inlet cylinder.

[0015] As a further optimization of the present invention, the rotary drive assembly includes a drive motor, a transmission belt and two pulleys. The drive motor is fixedly installed on the outside of the liquid inlet cylinder, and the two pulleys are respectively fixed to the drive end of the drive motor and the rotating end of the cylinder, and the two pulleys are connected by the transmission belt.

[0016] As a further optimization of the present invention, the liquid inlet cylinder includes a cylinder with openings at both ends, two sealing plates, and two support frames. The two sealing plates are detachably installed at both ends of the inner side of the cylinder, and the two ends of the outer side are rotatably connected to the two sealing plates. The two support frames are fixedly installed at both ends of the liquid inlet cylinder, and the bottom of the two support frames is detachably installed to the top of the treatment tank body.

[0017] As a further optimization of the present invention, the number of the partition plates is set to four, and the surface of the partition plates is provided with an anti-corrosion coating.

[0018] As a further optimization of the present invention, the stirring mechanism consists of three rotary mixers, all of which are installed on the top of the treatment tank body, and the three rotary mixers respectively stir the wastewater in different cavities of the treatment tank body.

[0019] The beneficial effects of this invention are as follows:

[0020] The treatment agent addition mechanism of this invention adopts a modular cavity isolation design. A detachable rotary drum pretreatment module is integrated at the liquid inlet end. Four radial sliding partition plates dynamically divide the cavity into independent pretreatment units. Each unit sequentially completes the static water inlet, quantitative locking of the agent, closed stirring and directional liquid discharge process. Physical isolation eliminates dynamic interference of water flow.

[0021] The mechanical cycle control is adopted, which uses the low-speed rotation of the drum to drive the periodic displacement of the pretreatment chamber. Combined with the gradually expanding guide and discharge port, the mixed liquid is spread smoothly, forming a working cycle of "discrete treatment-continuous discharge", which ensures the mixing time of a single chamber and maintains the system's processing throughput.

[0022] It adopts a built-in three-dimensional mixing structure and integrates curved surface stirring components in the rotating drum shaft system. During the rotation of the cavity, vertical swirling flow and radial shear flow are simultaneously excited, and the mass transfer efficiency in a limited space is enhanced through multi-directional eddy coupling.

[0023] The treatment agent addition mechanism system fundamentally solves the contradiction between dynamic dosing accuracy and mixing uniformity: the static dosing environment of the pretreatment chamber replaces the flow sensing closed-loop control, while the chamber geometric constraints and the composite flow field generation mechanism work together to improve the hybrid power performance, and finally achieve the process indicators that can only be achieved by traditional electronic control systems through a purely mechanical structure.

[0034] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0035] Please refer to the following: Figures 1 to 3A textile wastewater treatment device includes: a treatment tank body 1, a stirring mechanism 2, and a treatment agent addition mechanism 3. The treatment agent addition mechanism 3 is installed at the water inlet end of the treatment tank body 1 and includes an inlet cylinder 31, an inlet pipe 32, a treatment agent delivery pipe 33, a rotating drum 34, a rotation drive assembly 35, a stirring assembly 36, and four partition plates 38. The inlet cylinder 31 is detachably installed on one side of the treatment tank body 1. Both the inlet pipe 32 and the treatment agent delivery pipe 33 are connected to the outside of the inlet cylinder 31. The inlet pipe 32 is connected to an external wastewater delivery mechanism, and the treatment agent delivery pipe 33 is connected to an external treatment agent delivery mechanism. The inlet pipe 32 is located at the upper left of the inlet cylinder 31, and the treatment agent delivery pipe 33 is located at the top center of the inlet cylinder 31. The bottom of the inlet cylinder 31 has a drain port 39 facing one side of the treatment tank body 1, and the rotating drum 34 is coaxially rotatably installed inside the inlet cylinder 31. Four partition plates 38 are evenly slidably installed along the outer circumference of the rotating cylinder 34. The ends of the four partition plates 38 away from the rotating cylinder 34 are slidably attached to the inner wall of the inlet cylinder 31. A pretreatment chamber for temporary storage of a certain amount of wastewater is formed between every two partition plates 38. The surface of the partition plates 38 is provided with an anti-corrosion coating. A rotary drive assembly 35 is connected to one end of the rotating cylinder 34 for transmission. The rotary drive assembly 35 drives the rotating cylinder 34 to rotate inside the inlet cylinder 31. An agitator assembly 36 is installed on the rotating cylinder 34 and agitates the wastewater stored in each pretreatment chamber.

[0036] It should be noted that when using the above-mentioned treatment device to treat textile wastewater, the wastewater is introduced into the inlet cylinder 31 through the inlet pipe 32 and enters the corresponding pretreatment chamber. The rotating drive assembly 35 drives the rotating drum 34 to rotate slowly, and the partition plate 38 rotates with the rotating drum 34, so that the first pretreatment chamber containing wastewater gradually moves away from the inlet pipe 32. At the same time, the treatment agent is quantitatively introduced into the pretreatment chamber through the treatment agent delivery pipe 33. Then, the next pretreatment chamber moves to the position corresponding to the inlet pipe 32, and wastewater begins to enter the pretreatment chamber, while no more wastewater enters the first pretreatment chamber. The agitator 36 agitates the wastewater in the first pretreatment chamber, which can quickly mix the treatment agent and wastewater. Since the wastewater temporarily stored in the pretreatment chamber... The amount is relatively small, and the volume of wastewater remains basically unchanged during the process. In addition, the rotating drum 34 rotates at a low speed, keeping the wastewater in a slow flow state. At this time, the treatment agent and wastewater can be mixed quickly and evenly, and the amount of treatment agent added can also be kept precise. Since there is a certain amount of time between the first pretreatment chamber moving to the drain port 39, the stirring component 36 is sufficient to fully mix the wastewater and treatment agent during this period. When the first pretreatment chamber moves to the drain port 39, the mixed wastewater will be discharged directly from the drain port 39 into the treatment tank body 1. Then the second pretreatment chamber moves to the drain port 39 and continues to discharge the mixed wastewater. In this way, the wastewater can be continuously introduced into the treatment tank body 1 without having too much impact on the wastewater delivery speed.

[0037] Please refer to the following: Figures 3 to 5 The stirring assembly 36 includes a rotating drive and four stirring blades 361. The rotating drive is located inside the rotating drum 34. The four stirring blades 361 are uniformly rotated and installed along the outer circumference of the rotating drum 34, and each stirring blade is located between two adjacent partition plates 38. The rotating drive is connected to the four stirring blades 361 for transmission, and the rotating drive drives several stirring blades 361 to rotate synchronously with the rotating drum 34. The rotating drive includes a fixed gear 362 and a transmission part in the same number as the stirring blades 361. The axis of the fixed gear 362 coincides with the axis of the rotating drum 34, and one side of the fixed gear 362 is fixed to the liquid inlet cylinder 31. Several transmission parts are evenly distributed around the outside of the fixed gear 362. The transmission part includes a transmission gear 363 and two bevel gears 364. The transmission gear 363 meshes with the outside of the fixed gear 362. One bevel gear 364 is fixed to one side of the corresponding transmission gear 363, and the other bevel gear 364 is fixed to the rotating end of the stirring blades 361. The two bevel gears 364 mesh with each other, and the radius of the fixed gear 362 is at least twice that of the transmission gear 363.

[0038] It should be noted that when the above-mentioned stirring assembly 36 is in use, the rotating drum 34 starts to rotate under the drive of the rotation drive assembly 35. Since the fixed gear 362 is fixed to the liquid inlet cylinder 31, it will not rotate with the rotating drum 34. However, the transmission part and the stirring blade 361 rotate with the rotating drum 34. The transmission gear 363 starts to rotate around the outside of the fixed gear 362. Through the rotation of the transmission gear 363, the two bevel gears 364 can be driven to rotate together, so that the stirring blade 361 can rotate in the corresponding pretreatment chamber, which can stir and mix the wastewater.

[0039] Please refer to the following: Figure 5 Based on the above-mentioned agitation component 36 scheme, the present invention is further optimized as follows: the fixed gear 362 is an incomplete gear with a non-meshing section, and the non-meshing section of the incomplete gear corresponds to the position of the liquid inlet pipe 32.

[0040] It should be noted that, with the above-mentioned optimization scheme, when the stirring blade 361 moves to the position corresponding to the liquid inlet pipe 32, the transmission gear 363 corresponding to the stirring blade 361 moves to the non-meshing section of the incomplete gear 362, so that the transmission gear 363 stops rotating, and the stirring blade 361 also stops rotating. In this way, when the wastewater enters the corresponding pretreatment chamber, the problem of wastewater splashing in all directions due to the rotation of the stirring blade 361 can be avoided.

[0041] Please refer to the following: Figure 4 , Figure 6 , Figure 7 and Figure 8 Based on the above-mentioned processing device, the present invention is further optimized as follows: The inlet cylinder 31 is provided with a contraction drive assembly 37 for driving the partition plate 38 to contract towards the inside of the rotating cylinder 34. The contraction drive assembly 37 includes a track plate 371, and the same number of sliding wheels 372 as the partition plate 38, and a return spring 375. The track plate 371 is fixedly installed inside the inlet cylinder 31. A traction groove 373 is provided on one side of the track plate 371. Several sliding wheels 372 are all in rolling connection with the traction groove 373. The traction groove 373 is formed by the rotation... The cylinder 34 is composed of a first arc groove coaxial with the cylinder body 31 and a second arc groove with the center facing the inside of the inlet cylinder body 31. The second arc groove is located near the outlet 39. The inner side of the rotating cylinder 34 is provided with a movable groove 374 corresponding to the partition plate 38. One end of the four sliding wheels 372 slides through the corresponding movable groove 374 and is fixed to one side of the corresponding partition plate 38. One end of the four return springs 375 is fixed to one side of the four sliding wheels 372, and the other end of the four return springs 375 is fixed to the inner side of the corresponding movable groove 374.

[0042] It should be noted that during use, the rotating drum 34 begins to rotate under the drive of the rotating drive assembly 35, while the partition plate 38 rotates along with the rotating drum 34. As the partition plate 38 moves from the inlet pipe 32 to the outlet position, the sliding wheel 372 first rolls along the first arc groove. When the partition plate 38 reaches the outlet position, the sliding wheel 372 enters the second arc groove and begins to roll along it, causing the corresponding partition plate 38 to gradually slide and retract towards the inside of the rotating drum 34. Meanwhile, the return spring 375... The wastewater is compressed synchronously, causing the pretreatment chamber to open rapidly during the contraction of the partition plate 38, allowing the wastewater to flow out quickly. Additionally, the outer side of the partition plate 38, through its contact with the rotating drum 34, scrapes off impurities adsorbed on its surface. These scraped impurities fall into the treatment tank body 1 below under gravity. Thus, by setting up this contraction drive assembly 37, the wastewater discharge speed is accelerated, allowing the mixed wastewater to quickly enter the treatment tank body 1 for sedimentation. Simultaneously, the partition plate 38 achieves a self-cleaning function. After the sliding wheel 372 rolls to the deepest position of the second arc groove, it begins to extend the partition plate 38 outwards towards the rotating drum 34. The return spring 375 provides an outward force to the partition plate 38, allowing it to extend smoothly until the rolling wheel re-enters the first arc groove, completing the extension and retraction of the partition plate 38.

[0043] Please refer to the following: Figure 3 The partition plate 38 consists of a rectangular plate and three sealing strips. Several sealing strips are fixedly installed on the side of the rectangular plate that contacts the inner side of the liquid inlet cylinder 31. The sealing strips are used to seal the gap between the rectangular plate and the inner side of the liquid inlet cylinder 31.

[0044] It should be noted that the sealing strip can be made of fluororubber with good wear resistance. The sealing strip not only plays a sealing role, but also scrapes the impurities adsorbed on the inner wall of the liquid inlet cylinder 31 by sliding contact with the end of the sealing strip during the rotation of the partition plate 38.

[0045] Please refer to the following: Figure 6 The rotary drive assembly 35 includes a drive motor 351, a transmission belt 352, and two pulleys 353. The drive motor 351 is fixedly installed on the outside of the liquid inlet cylinder 31. The drive motor 351 can be a servo motor, and its speed can be adjusted according to actual usage requirements. The two pulleys 353 are respectively fixed to the drive end of the drive motor 351 and the rotating end of the rotating drum 34, and the two pulleys 353 are connected by the transmission belt 352.

[0046] It should be noted that when the above-mentioned rotary drive assembly 35 is in use, the drive motor 351 rotates, which drives the pulley 353 connected to it to rotate. Under the transmission action of the transmission belt 352, the rotating drum 34 can finally rotate synchronously, so as to realize the low-speed rotation of the rotating drum 34 inside the liquid inlet cylinder 31.

[0047] Please refer to the following: Figure 9 The liquid inlet cylinder 31 includes a cylinder 311 with openings at both ends, two sealing plates 312, and two support frames 313. The two sealing plates 312 are detachably installed at both ends of the inner side of the cylinder 311, and the two ends of the outer side are rotatably connected to the two sealing plates 312. The two support frames 313 are fixedly installed at both ends of the liquid inlet cylinder 31, and the bottom of the two support frames 313 is detachably installed at the top of the treatment tank body 1.

[0048] Please refer to the following: Figure 1 The stirring mechanism 2 consists of three rotary mixers, all of which are installed on the top of the treatment tank body 1. The three rotary mixers stir the wastewater in different cavities of the treatment tank body 1 respectively.

[0049] It should be noted that the mixed wastewater enters the main body of the treatment tank 1 and passes through the coagulation chamber and sedimentation chamber of the main body of the treatment tank 1. The wastewater is further stirred by the corresponding stirring mechanism 2 to accelerate the sedimentation of impurities in the wastewater.

[0050] The embodiments of this specific implementation have been described above. However, this embodiment is not limited to the specific implementation described above. The specific implementation described above is merely illustrative and not restrictive. Those skilled in the art can make many other forms based on the guidance of this embodiment, all of which are within the protection scope of this embodiment.
