Abstract
Description
Technical Field
[0001] This invention relates to the technical field of textile dyeing wastewater treatment, and particularly to a textile dyeing wastewater recycling treatment device and treatment process. Background Technology
[0002] The dyeing and printing industry consumes a large amount of water, and the wastewater is complex in composition, containing fiber dirt, dyes, auxiliaries, etc. It is characterized by high organic matter concentration, deep color, and unstable water quality, and is classified as difficult-to-treat industrial wastewater.
[0003] Currently, the mainstream textile dyeing wastewater treatment technology in the industry mainly follows a process of physical pretreatment, followed by biochemical reaction, deep purification, and finally recycling. Among these, physical pretreatment and biochemical reaction are key steps in removing suspended solids, colloids, and some organic matter from wastewater. Related treatment devices often rely on various reaction tanks, reaction tanks, filter tanks, and other tank structures to achieve wastewater retention, reaction, and solid-liquid separation.
[0004] In the reaction tank, suspended solids and sludge in the dyeing and printing wastewater, while some settle to the bottom, still adhere to the side walls as sticky pollutants. Since the equipment lacks a dedicated cleaning structure, these pollutants accumulate continuously. This leads to the formation of a hardened sediment layer, which corrodes the tank and shortens its lifespan. Furthermore, it reduces the effective volume of the tank, lowering reaction and separation efficiency, affecting effluent quality, and the detached sediment layer can clog equipment, increasing maintenance costs.
[0005] Chinese patent CN111466742A discloses a wastewater treatment tank for textile dyeing and printing. It includes a main body with a wastewater inlet at the top, a primary filter installed at the inlet, a horizontal fixing bar in the middle of the tank body, secondary filters on both sides of the fixing bar, and a second filter plate inclined below the secondary filters. Dyeing and printing wastewater enters the tank through the inlet, undergoes primary filtration, and then a dosing tank adds treatment agents. Under the stirring of an impeller, the treatment agents and wastewater react fully in the wastewater treatment chamber. The reacted wastewater is then filtered twice by the secondary filter and the second filter plate before being discharged through a drain pipe. This wastewater treatment tank allows for continuous addition of wastewater and continuous discharge of treated wastewater, resulting in high treatment efficiency. Furthermore, the wastewater treatment chamber and storage chamber are arranged vertically, minimizing space requirements.
[0006] However, the aforementioned textile dyeing wastewater treatment ponds still have some shortcomings in actual use:
[0007] When wastewater flows through the pool, most of it settles at the bottom due to gravity. However, some highly viscous pollutants are washed away by the water flow or adhere to the side walls of the pool by gravity. When the sediment layer accumulates to a certain extent, the company needs to stop the machine to clean the pool. Current cleaning methods mostly rely on manual entry into the pool to use high-pressure water guns for washing or scraping with scrapers. This is not only labor-intensive and inefficient, but also poses safety risks to personnel, such as oxygen deficiency or residual toxic gases in the pool. At the same time, stopping the machine for cleaning will interrupt the wastewater treatment process, affect the continuous operation of the fabric printing and dyeing production line, and cause economic losses.
[0008] Therefore, based on the above-mentioned viewpoints, it is of great significance to improve and perfect the wastewater treatment ponds for textile printing and dyeing. This will not only enable the cleaning of the ponds, but also reduce labor intensity, improve cleaning efficiency, and ensure personnel safety. Summary of the Invention
[0009] To address the aforementioned problems, this invention provides a wastewater recycling treatment device and process for textile printing and dyeing.
[0010] On one hand, a wastewater recycling treatment device for textile printing and dyeing includes a reaction tank, a slide plate that slides along the length of the reaction tank, a filter plate that is installed on the slide plate, a treatment box that is provided on one side of the reaction tank, and a scraping assembly, a moving assembly and a treatment component that are provided in the reaction tank.
[0011] The scraping assembly includes a first cleaning component and a second cleaning component. The first cleaning component is disposed on the slide plate for scraping the side wall of the reaction tank, and the second cleaning component is disposed on the reaction tank for scraping the two side walls of the reaction tank in the width direction. The moving assembly is used to drive the slide plate to move within the reaction tank, and the processing component is disposed within the processing box for cleaning the filter plate.
[0012] Preferably, the cleaning component includes scraper plates symmetrically slidably mounted on both sides of the slide plate along the width direction of the slide plate. The scraper plates are horizontally arranged and slide longitudinally along the slide plate to clean the inner sidewall of the reaction tank. Symmetrically through-holes are provided on both sides of the slide plate. A first screw is rotatably mounted in the through-holes via bearings. The first screw is vertically arranged. The through-holes penetrate the sidewall of the slide plate laterally. A mounting block that slides in the through-holes is threaded onto the first screw. The end of the mounting block away from the first screw extends out of the through-holes. The scraper plate is located at the end of the mounting block that extends out of the through-holes.
[0013] Preferably, a control gear is fixedly installed after the upper end of the first screw passes through the slide plate, and a support frame is provided between the upper end of the reaction tank and the upper end of the processing box, and a control rack that meshes with the control gear is installed on the support frame.
[0014] Preferably, the moving component includes two sets of moving screws, which are respectively arranged on both sides of the upper end of the reaction tank along the length direction. Moving blocks are threaded on the moving screws, and rotating shafts are installed on the moving blocks in the direction of the reaction tank. The two ends of the slide plate are respectively connected to the corresponding rotating shafts.
[0015] Preferably, a drive gear ring is fitted onto the rotating shaft via a keyway, and drive racks are symmetrically installed at the connection points on the reaction tank and the processing box. The drive racks and drive gear rings correspond one-to-one and are in a meshing relationship.
[0016] Preferably, multiple filter strips are equidistantly arranged along the height direction of the filter plate. The filter strips are L-shaped structures composed of flat sections and hook sections, and multiple filter holes are opened on the flat sections of the filter strips.
[0017] Preferably, the processing component includes a cleaning screw, a U-shaped placement groove is provided along the inner wall of the processing box, a cleaning plate is slidably disposed in the placement groove, the cleaning screw is rotatably disposed at the bottom of the placement groove, and the cleaning plate is threadedly connected to the cleaning screw.
[0018] Preferably, the cleaning plate has multiple cleaning slots that are compatible with the filter strips.
[0019] Preferably, the second cleaning component includes a scraper that is slidably disposed on one side of the reaction tank along its length. The scraper slides longitudinally on the inner wall of the reaction tank and is in contact with the inner wall of the reaction tank.
[0020] Lifting components are provided on both sides of the reaction tank in the width direction. The lifting components include a first winding shaft and a second winding shaft that are rotatably mounted on the reaction tank. A stop post is installed at the bottom of the reaction tank. Pull ropes are provided at both ends of the first winding shaft and the second winding shaft that pass around the stop post. The pull ropes are connected to the scraper bar.
[0021] On the other hand, a wastewater recycling treatment process for textile printing and dyeing is described below:
[0022] S1. The sliding plate is driven to move along the length of the reaction tank by the moving component. At the same time, the cleaning components one and two scrape and clean the side wall of the reaction tank, and the filter plate filters the impurities in the wastewater.
[0023] S2. When the slide plate moves to the processing box, the slide plate flips over and enters the processing box, and the processing component cleans the filter plate.
[0024] S3. During the cleaning process, the filter plate is vibrated by a vibrating component to enhance the cleaning effect.
[0025] S4. After cleaning is complete, the moving component drives the slide plate to reset and the next cycle begins.
[0026] In summary, this application includes at least one of the following beneficial technical effects:
[0027] I. The present invention utilizes a scraping assembly with a first cleaning component that slides up and down via a first screw and, in conjunction with a spring, adheres tightly to the side wall of the reaction tank, effectively scraping away attached suspended solids and sludge. The second cleaning component is controlled by a winding shaft and a pull rope to move back and forth along the height direction, specifically cleaning the two side walls of the reaction tank in the width direction that the sliding plate cannot reach. The two components work together to achieve full coverage cleaning of the side walls, preventing pollutants from hardening and forming a corrosion layer, and extending the service life of the tank.
[0028] Second, this invention prevents filter bar clogging by timely cleaning of the filter plates through the treatment box, ensuring that the filter plates maintain stable filtration capacity over a long period of time, and ensuring that the suspended solids content of the treated wastewater meets the standards, thus laying the foundation for subsequent recycling.

Detailed Implementation
[0042] The following combination Figures 1-11 The embodiments of the present invention will be described in detail below.
[0043] This application discloses a wastewater recycling treatment device and process for textile dyeing and printing. The invention is mainly applied in the process of dyeing and printing wastewater treatment. In terms of technical effect, it can prevent some highly viscous pollutants from being washed away by water flow or adhering to the surface of the pool side wall by gravity. When the sediment layer accumulates to a certain extent, the enterprise needs to stop the machine to clean the pool, which has the problems of high labor intensity and low cleaning efficiency. Example
[0044] Reference Figure 1 and Figure 2 As shown, a fabric dyeing wastewater recycling treatment device includes a reaction tank 1. A slide plate 10 is slidably arranged in the reaction tank 1 along its length direction. By sliding the slide plate 10 in the reaction tank 1 along its length direction, impurities deposited on the side wall of the reaction tank 1 can be wiped away.
[0045] The slide plate 10 has a U-shaped frame structure and a filter plate 11 is installed on its inner side. During the movement, the filter plate 11 can filter impurities in the sewage and impurities falling from the side wall. A treatment box 12 is provided on one side of the reaction tank 1. When the slide plate 10 moves into the treatment box 12, it can clean the filter plate 11 to ensure the working efficiency of the filter plate 11.
[0046] Reference Figure 1 , Figure 2 and Figure 10 As shown, reaction tank 1 is equipped with:
[0047] The scraping component 2 improves the cleaning effect of the slide plate 10 on the reaction tank 1, and cleans the inner wall of the reaction tank 1 through the scraping component 2;
[0048] The movable component 3 slides within the reaction tank 1, and the sliding plate 10 is controlled to move within the reaction tank 1 using the movable component 3;
[0049] The processing component 4 is used to clean residual impurities on the filter plate 11. The impurities on the filter plate 11 are cleaned in the processing box 12.
[0050] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 The diagram shows a structural schematic for cleaning the reaction tank 1. Specifically, the scraping assembly 2 includes a cleaning component 20, which includes scraping plates 200 symmetrically slidably mounted on both sides of the slide plate 10 along the width direction of the slide plate 10. The scraping plates 200 are horizontally arranged and slide longitudinally along the slide plate 10 to clean the inner wall of the reaction tank 1. Symmetrically arranged vertically through receiving holes are provided on both sides of the slide plate 10. A first screw 201 is rotatably mounted in the receiving hole through a bearing. The first screw 201 is vertically arranged. The receiving hole extends laterally through the side wall of the slide plate 10. A mounting block 202 that slides in the receiving hole is threaded onto the first screw 201. One end of the mounting block 202 away from the first screw 201 extends out of the receiving hole. The scraping plate 200 is located at the end of the mounting block 202 that extends out of the receiving hole.
[0051] Specifically, the mounting block 202 has a sliding hole at one end extending from the receiving hole, a sliding block is slidably disposed in the sliding hole, a spring is connected between the sliding block and the inner wall of the sliding hole, and the mounting block 202 is fixedly connected to the end of the sliding block away from the spring.
[0052] During the movement of the slide plate 10, the scraper plate 200 slides up and down under the control of the first screw 201. The scraper plate 200 removes impurities from the side wall of the reaction tank 1, ensuring the cleanliness of the side wall of the reaction tank 1 and preventing suspended solids and sludge from forming a hardened sediment layer.
[0053] Reference Figure 1 and Figure 2 The diagram shows a schematic of the structure controlling the movement of the slide plate 10. Specifically, the moving component 3 includes two sets of moving screws 30, which are respectively set on the two sides of the upper end of the reaction tank 1 along the length direction. Both ends of the moving screws 30 are rotatably mounted on the outer wall of the reaction tank 1 through bearings. Moving blocks 31 are threaded on the moving screws 30. The moving blocks 31 are slidably set along the length direction of the upper end of the reaction tank 1. Rotating shafts 70 are rotatably mounted on the moving blocks 31 in the direction of the reaction tank 1. Both ends of the slide plate 10 are respectively connected to the corresponding rotating shafts 70.
[0054] One of the movable screws 30 is connected to the output end of the motor (not shown in the figure). The motor is mounted on the outer wall of the reaction tank 1 through the motor base. The two sets of movable screws 30 can be connected by sprocket and chain transmission. The motor controls the rotation of the corresponding movable screw 30. Under the sprocket and chain transmission, the two sets of movable screws 30 can rotate synchronously, thereby moving the movable block 31 along the length of the reaction tank 1. The movable block 31 can then move the slide plate 10 in the reaction tank 1 through the rotating shaft 70.
[0055] Reference Figure 1 , Figure 2 and Figure 5 The diagram shows the structure of the scraper 200 that controls the up and down sliding. Specifically, a control gear 52 is fixedly installed after the upper end of the first screw 201 passes through the slide plate 10. A support frame 53 is provided between the upper end of the reaction tank 1 and the upper end of the processing box 12. A control rack 54 that meshes with the control gear 52 is installed on the support frame 53.
[0056] During the movement of the slide plate 10, the control gear 52 on the first screw 201 will mesh with the control rack 54 to drive the first screw 201 to rotate. As a result, the scraper 200 connected to the first screw 201 will move up and down during the movement of the slide plate 10 to scrape and clean the side wall of the reaction tank 1.
[0057] Reference Figure 1 , Figure 8 and Figure 9 The diagram shows the structure that ensures the filtration effect of impurities in reaction tank 1. Specifically, multiple filter strips 60 are equidistantly arranged on the filter plate 11 along its height direction. Each filter strip 60 has an L-shaped structure composed of a flat section and a hook section. The flat section is inclined upward and fixedly installed on the vertical surface of the filter plate 11. The hook section is located above the flat section and is bent inward toward the filter plate 11. Multiple filter holes 61 are opened on the flat section of the filter strip 60.
[0058] The purpose of setting the filter strip 60 is that, since the filter plate 11 needs to slide back and forth in the reaction tank 1, when impurities are filtered on one side of the filter plate 11, the movement of the filter plate 11 may cause the impurities on the filter plate 11 to fall off under the flushing of the water flow. By setting the filter strip 60, the impurities flushed by the water flow will be collected by the filter strip 60 during the movement. The L-shaped shape can more effectively intercept the impurities, and the multiple filter holes 61 can discharge water.
[0059] Reference Figure 1 and Figure 2The diagram shows the structure that drives the filter plate 11 to flip. Specifically, a drive gear ring 50 is fitted on the rotating shaft 70 through a keyway, and drive racks 51 are symmetrically installed at the connection points on the reaction tank 1 and the treatment box 12. The drive racks 51 and the drive gear rings 50 correspond one-to-one and are in a meshing relationship.
[0060] When it is necessary to clean the filter plate 11 on the slide plate 10, the slide plate 10 is moved to the treatment box 12 by moving the screw 30 until the drive gear ring 50 meshes with the drive rack 51, causing the slide plate 10 to rotate 360° and enter the treatment box 12, where it is then cleaned.
[0061] Reference Figure 10 and Figure 11 The diagram shows a structural schematic for cleaning the filter plate 11. Specifically, the processing component 4 includes a cleaning screw 40. A U-shaped mounting groove 41 is formed along the inner wall of the processing box 12. A cleaning plate 42 is slidably disposed in the mounting groove 41. The cleaning screw 40 is rotatably disposed at the bottom of the mounting groove 41. The cleaning plate 42 is threadedly connected to the cleaning screw 40. A limiting rod is also installed at the upper end of the mounting groove 41. The limiting rod passes through the upper end of the cleaning plate 42. The cleaning screw 40 and the cleaning plate 42 are threadedly engaged, and the limiting rod ensures that the cleaning plate 42 will not deflect. This ensures that the rotation of the cleaning screw 40 can control the sliding of the cleaning plate 42 in the mounting groove 41. Both ends of the cleaning screw 40 are rotatably mounted on the side wall of the processing box 12 through bearings. After the cleaning screw 40 passes through the side wall of the processing box 12, it is connected to a motor (not shown in the figure) installed on the outer wall of the processing box 12.
[0062] After the slide plate 10 carries the filter plate 11 into the processing box 12, the cleaning screw 40 is rotated to drive the cleaning plate 42 in the placement groove 41 to slide along the width direction of the processing box 12. During the sliding process, the cleaning plate 42 will contact the surface of the slide plate 10 and the filter plate 11 to scrape off the impurities remaining on them.
[0063] Reference Figure 11 The diagram shows a structural schematic for cleaning the filter strip 60. Specifically, the cleaning plate 42 has multiple cleaning grooves 43 that are adapted to the filter strip 60. As the cleaning plate 42 moves, the cleaning grooves 43 adapt to the filter strip 60, simultaneously cleaning impurities on the filter strip 60.
[0064] Reference Figure 6 and Figure 7 The diagram shows a structure for improving the cleaning effect of reaction tank 1. Specifically, a second cleaning component 21 is also provided in reaction tank 1. The second cleaning component 21 includes a scraper 210 that is slidably disposed on one side of the reaction tank 1 along its length. The scraper 210 slides longitudinally on the inner wall of reaction tank 1 and is in contact with the inner wall of reaction tank 1.
[0065] The scraper 210 can slide along the height direction of the reaction tank 1, thereby cleaning the other side wall of the reaction tank 1, preventing the slide plate 10 from not being able to contact the two sides of the reaction tank 1 in the width direction, which would result in the two sides of the reaction tank 1 in the width direction not being cleaned.
[0066] Reference Figure 6 and Figure 7 The diagram shows a schematic of the structure controlling the lifting and lowering of the scraper 210. Specifically, lifting components 22 are provided on both sides of the reaction tank 1 in the width direction. The lifting components 22 include a first winding shaft 221 and a second winding shaft 222 rotatably mounted on the reaction tank 1. A stop post 223 is installed at the bottom of the reaction tank 1. The first winding shaft 221 and the second winding shaft 222 are connected to a pull rope 224 at both ends, which passes around the stop post 223. The pull rope 224 is connected to the scraper 210.
[0067] The first take-up shaft 221 and the second take-up shaft 222 are connected by gear transmission so that they rotate in opposite directions. The first take-up shaft 221 is connected to the moving screw 30 by belt transmission. The first take-up shaft 221 and the second take-up shaft 222 work together to control the pull rope 224 to pull the scraper 210 up and down in the reaction tank 1 to clean the side wall of the reaction tank 1. Example
[0068] Based on Embodiment 1, in order to further improve the cleaning effect on the filter plate 11, a vibrating element is proposed, which is beneficial to vibrate the filter plate 11 during the cleaning process and improve the cleaning effect on the filter plate 11.
[0069] Reference Figure 3 , Figure 10 and Figure 11 As shown, this is a structural schematic diagram to improve the cleaning effect of the filter plate 11; specifically, a groove 71 is provided on the rotating shaft 70, and T-shaped sliders 72 are symmetrically installed on the upper side wall of the slide plate 10. The sliders 72 are horizontally slidably arranged in the corresponding grooves 71.
[0070] The slide plate 10 slides in the groove 71 via the trapezoidal slider 72, so that the slide plate 10 connected to the slider 72 can slide back and forth along the length of the reaction tank 1.
[0071] The cleaning plate 42 is a horizontal spring telescopic structure with a control groove on the telescopic end. A drive plate 73 is installed between the two control grooves. Wave grooves 74 are equally spaced on the drive plate 73. A contact block 75 that abuts against the wave groove 74 is provided in the control groove.
[0072] When the cleaning plate 42 moves inside the processing box 12, the contact block 75 on the cleaning plate 42 will abut against the wave groove 74 on the driving plate 73. Since the cleaning plate 42 is a spring telescopic structure, the two work together to make the cleaning plate 42 extend and retract. In the process of cleaning the filter strip 60 on the slide plate 10, the cleaning plate 42 can also pull the filter strip 60 to move synchronously with the telescopic end of the cleaning plate 42, which has a certain vibration effect. By driving the filter plate 11 to vibrate, the cleaning effect of the filter plate 11 is improved.
[0073] During operation: First, the motor drives the moving screw 30 to rotate, which moves the slide plate 10 along the length of the reaction tank 1 via the moving block 31. When the slide plate 10 moves, the control gear 52 meshes with the rack to drive the first screw 201 to rotate. The scraper plate 200 slides up and down to scrape impurities on the side wall. The moving screw 30 synchronously drives the winding shaft to rotate, and the pull rope 224 pulls the scraper strip 210 up and down to clean the side wall that the slide plate 10 cannot reach. At the same time, the filter plate 11 moves with the slide plate 10, the L-shaped filter strip 60 intercepts sewage and scrapes off impurities, and the filter hole 61 drains water.
[0074] Step 2: The slide plate 10 is moved to the processing box 12, the drive gear ring 50 meshes with the rack, and the slide plate 10 is flipped into the processing box 12. At the same time, the cleaning screw 40 rotates, and the cleaning plate 42 slides. The cleaning groove 43 is adapted to the filter strip 60 to scrape off impurities.
[0075] Step 3: When the cleaning plate 42 moves, the contact block 75 touches the wave groove 74, and the spring extends and retracts, causing the cleaning plate 42 to reciprocate, which drives the filter plate 11 to vibrate and enhance the cleaning.
[0076] Step 4: The reverse drive moves the screw 30, the slide plate 10 flips and resets, all components return to their positions, and the next cycle begins.
[0077] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects.
[0078] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
