Description

Technical Field

[0001] The present invention relates to the technical field related to fiber dyeing wastewater treatment, and in particular to a fiber dyeing wastewater treatment device. Background Art

[0002] During the dyeing process of colored yarn production, a large amount of wastewater is generated. Compared with ordinary fiber dyeing wastewater, this type of wastewater has a more complex composition. In addition to containing conventional fiber debris, dyes, and auxiliaries, because colored yarn is blended with a variety of different colored fibers, the wastewater also contains a variety of dyes of different colors, resulting in extremely high chroma and difficulty in removal. At the same time, the special functional auxiliaries used in colored yarn production further increase the chemical oxygen demand (COD) and biochemical oxygen demand (BOD) values of the wastewater, greatly increasing the difficulty of treatment.

[0003] A conventional silk / wool fiber dyeing method and its post-dyeing wastewater treatment device, such as that disclosed in Chinese Patent Publication No. CN114717862B, comprises pre-drying silk / wool blended fibers, followed by plasma pre-treatment; dyeing wool in an acidic bath; dyeing silk in an alkaline bath; soaping under weakly alkaline conditions; and then washing with water. The treatment device comprises a treatment tank having a plurality of water flow channels within which are rotatably connected a plurality of water treatment components perpendicular to the flow direction of the water, with portions of the water treatment components exposed above the water surface; a filter plate disposed below the water flow channels, and an air flotation device disposed below the filter plate; and a scraper disposed between the filter plate and the water flow channels. The scraper comprises a plurality of scraping plates, each with a V-shaped hook at the bottom and bristles at the end of the V-shaped hook. The present invention improves the uniformity of dyeing of the silk / wool blended fibers, reduces wastewater discharge, and reduces environmental pollution.

[0004] The above-mentioned prior art patent only uses the scraper and V-shaped hook on the scraper to clean the impurities on the filter plate and the scum on the water surface. Compared with the fiber dyeing wastewater treatment equipment, its scraping and scum collection process is not precise enough. When faced with the complex scum in the colored spinning wastewater, it cannot be cleaned efficiently. Scum often remains, resulting in incomplete scum collection, and it is also difficult to effectively clean the scum stuck to the scraper and V-shaped hook, resulting in some of the scum returning to the sewage, causing secondary pollution, and further increasing the environmental burden.

[0005] Based on this, the present application designs a wastewater treatment device for fiber dyeing. Summary of the Invention

Detailed implementation manners

[0036] The following further elaborates on this application with reference to the attached Figures 1 to 10 drawings for a more detailed description

[0037] An embodiment of this application discloses a sewage treatment device for fiber dyeing. By means of eddy current air flotation technology, the generated microbubbles carry pollutants to float to the water surface, forming foamy scum. Then, the slag scraping module 6 scrapes and centrally collects the scum on the water surface, significantly improving the collection effect of the scum.

[0038] Refer to Figures 1 to 6As shown in the figure, a sewage treatment device for fiber dyeing disclosed in this embodiment includes an air flotation cylinder 1, a dissolved air module 2, a vortex generator 3, a conveying module 4, an electric slider 5, a slag scraping module 6, a lifting module 7, and a collection module 8. The air flotation cylinder 1 is a fixed base. The middle part of the upper end of the air flotation cylinder 1 is communicated with an inlet, and the left side of the lower end of the air flotation cylinder 1 is communicated with an outlet. A switching control valve of the prior art can be added to the outlet to control the flow of sewage in the outlet. The dissolved air module 2 is installed at the outer wall position of the air flotation cylinder 1, and the release port of the dissolved air module 2 extends into the interior of the air flotation cylinder 1. Bubbles are injected into the sewage in the air flotation cylinder 1 through the dissolved air module 2. The dissolved air module (2) of the prior art, as an important part of the sewage treatment device for fiber dyeing, is a mature existing device based on the dissolved air flotation technology. The dissolved air is precipitated in the form of tiny bubbles in large quantities, and the bubble diameter is between 10 and 100 microns. These microbubbles are evenly dispersed in the sewage and can effectively adhere to the pollutants in the sewage. As the bubbles float upward, the pollutants also reach the water surface to form scum, creating conditions for subsequent collection and treatment by the slag scraping module, and thus realizing sewage purification. The vortex generator 3 is built into the bottom of the air flotation cylinder 1. By the rotation of the vortex generator 3, the bubbles are boosted to rise, thereby carrying the pollutants to float to the water surface to form foamy scum. The conveying module 4 moves horizontally through the electric slider 5. The existing electric slider is an automated modular component that realizes linear motion driven by a motor and is widely used in fields such as precision positioning, automated equipment, and robots. It realizes precise adjustment of position and speed. The electric slider 5 is installed at the inner side wall position of the upper end of the air flotation cylinder 1. The slag scraping module 6 is installed on the conveying module 4. The floating slag is centrally collected through the slag scraping module 6. The lifting module 7 used in cooperation with the slag scraping module 6 is installed at the left side position of the upper end of the air flotation cylinder 1. The collection module 8 is installed at the left side position of the air flotation cylinder 1. After the slag scraping module 6 moves to the leftmost side, the collected floating slag is blown into the collection module 8 for centralized collection.

[0039] During the actual operation process, the preliminarily filtered (removing impurities such as larger particle fiber debris) sewage is conveyed into the air flotation cylinder 1 through the inlet. After the quantitative conveyance is completed, microbubbles are released into the sewage through the dissolved air module 2, and the rotation of the vortex generator 3 is used to boost the bubbles to rise, thereby carrying the pollutants to float to the water surface to form foamy scum. The floating scum on the water surface is scraped off by the slag scraping module 6 until it moves to the leftmost side. At this time, a temporary assembly is formed between the lifting module 7 and the slag scraping module 6. The lifting module 7 rises to drive the slag scraping module 6 to rise, thereby blowing the floating slag on the slag scraping module 6 into the collection module 8.

[0040] Refer to Figure 6As shown in the figure, the eddy current generator 3 includes an electric turntable 31, a sleeve member 32, a sliding member 33, a stirring member 34, rolling beads 35, and an annular rail 36. The electric turntable 31 is built into the bottom of the air flotation cylinder 1. The existing electric turntable is an automated device that achieves precise rotational motion through motor drive and is widely used in fields such as industrial automation, robotics, display equipment, and scientific research experiments. The upper rotating head of the electric turntable 31 is sleeved with the sleeve member 32. The sliding member 33 is slidably arranged on the sleeve member 32. The stirring members 34 are evenly installed along the circumference of the sliding member 33. An inclined plate is installed at the upper end of the stirring member 34, and a connecting seat is installed at the lower end of the stirring member 34. Rolling beads 35 are rotatably arranged in the connecting seat, and the rolling beads 35 cooperate with the annular rail 36. The annular rail 36 is installed at the bottom of the air flotation cylinder 1, and the upper end surface of the annular rail 36 is of an annular corrugated structure.

[0041] During the actual operation process, the electric turntable 31 of the existing technology drives the sleeve member 32, the sliding member 33, and the stirring member 34 to perform synchronous horizontal rotation, causing the water flow to form a vortex during rotation. During the rotation process, the upper end surface of the annular rail 36 being of an annular corrugated structure and the up and down sliding of the sliding member 33 cause the stirring member 34 to form up and down micro-vibrations, preventing the fibers in the sewage from winding.

[0042] Refer to Figure 3 、 Figure 4 、 Figure 7 As shown in the figure, the conveying module 4 includes a conveying member 41, a pump body mechanism 42, and a cleaning mechanism 43. The conveying member 41 is slidably arranged between the electric sliders 5. The pump body mechanism 42 is installed at the right end of the conveying member 41, and the cleaning mechanism 43 is rotatably arranged at the left end of the conveying member 41.

[0043] During the actual process, the electric slider drives the conveying member 41 to perform left and right horizontal movement. When the slag scraping module 6 moves to the leftmost side, at this time, the lifting module 7 drives the slag scraping module 6 to rise until the highest position. At this time, the pump body mechanism 42 is powered on to start the air blowing operation, and the cleaning mechanism 43 rotates to clean the surface of the pushing plate 67 that has risen and been pushed to the leftmost side.

[0044] Refer to Figure 7 、 Figure 9 As shown in the figure, the pump body mechanism 42 includes a pump body 421, a battery 422, and a switch member 423. The pump body 421 is installed on the upper right end surface of the conveying member 41 through a base. The pump body 421 is of the existing technology. An insulating shell is installed on the conveying member 41, and the battery 422 and the switch member 423 built into the insulating shell are electrically connected to the pump body 421.

[0045] Refer to Figure 9As shown, the switch member 423 includes a conductive member 424 which is slidably arranged up and down in a sliding opening formed in the insulating housing. Insulating layers are laid on both the upper and lower end faces of the conductive member 424. A conductive block 425 used in cooperation with the conductive member 424 is installed at the lower end of the insulating housing.

[0046] During the actual operation process, after the slag scraping module 6 is driven by the lifting module 7 to rise to the highest position, the squeezed conductive member 424 rises and comes into contact with the conductive block 425. Subsequently, the overall passage of the pump body mechanism 42 is formed, and after being powered on, the pump body 421 performs air blowing operation.

[0047] Refer to Figure 4 、 Figure 9 As shown, an activity groove is formed in the middle of the conveying member 41. A conveying cavity 44 is formed at the right end of the activity groove. The conveying cavity 44 is connected to the pump body 421. A shunt cavity 45 is formed at the left end of the activity groove. Air conveying cavities 46 are evenly formed at the left end of the shunt cavity 45 from front to back. The middle of the air conveying cavity 46 is connected to the rear end of a rotating groove 47 which is formed in the conveying member 41.

[0048] Refer to Figure 4 As shown, the cleaning mechanism 43 includes a rotating member 431, fan blades 432, and a lightweight shaft 433. The rotating member 431 is horizontally rotatably arranged inside the rotating groove 47. Fan blades 432 are evenly installed on the outer wall of the rotating member 431 along its circumference. The lightweight shaft 433 is coaxially installed at the lower end of the rotating member 431. The material of the lightweight shaft 433 is lightweight, ensuring the smooth rotation of the lightweight shaft 433. Cleaning brush hairs are arranged around the lightweight shaft 433. A zero scale line is arranged inside the air flotation cylinder 1, and the lower end face of the lightweight shaft 433 is higher than the height of the zero scale line. Sewage entering from the inlet enters the air flotation cylinder 1 until its water level aligns with the zero scale line, ensuring that water droplets will not splash onto the power - carrying mechanisms above when agitating the sewage, and all the existing technologies in this application have a certain degree of waterproofness.

[0049] During the actual operation process, after the guiding plate 61 is driven by the lifting module 7 to rise to the highest position, at this time, the connecting cavity 63 formed in the middle of the guiding plate 61 is aligned and connected with the conveying cavity 44 and the shunt cavity 45. After being powered on, the pump body 421 distributes air to the slag scraping module 6 and the shunt cavity 45. The air in the shunt cavity 45 is blown out from its left - hand opening through the air conveying cavity 46. When passing through the air conveying cavity 46, the wind force pushes the fan blades 432 at the rear side of the rotating member 431, causing the lightweight shaft 433 to rotate. The cleaning brush hairs on the lightweight shaft 433 clean the surface of the pushing plate 67.

[0050] Refer to Figure 3 、 Figure 5 、 Figure 7 、 Figure 10As shown, the slag scraping module 6 includes a guiding plate 61, a towing head 62, a connecting cavity 63, a connecting frame 64, a slag scraping filter screen 65, a scraping plate 66, a pushing plate 67, a pressing rod 68, and a pressing mechanism 69. The upper half of the guiding plate 61 is slidably arranged up and down in the movable groove. The towing head 62 is installed on the upper end surface of the guiding plate 61. A connecting cavity 63 is formed in the middle of the guiding plate 61. A distribution cavity 611 is formed at the lower end of the guiding plate 61. The distribution cavity 611 is communicated with the connecting cavity 63. An air hole is formed at the left end of the distribution cavity 611. The connecting frame 64 is installed at the lower end of the guiding plate 61. The slag scraping filter screen 65 is installed inside the connecting frame 64. A scraping plate 66 with a loop structure is horizontally slidably arranged on the connecting frame 64. The floating slag on the slag scraping filter screen 65 is scraped and pushed to the left by the left-moving scraping plate 66. The pushing plate 67 is arranged between the scraping plate 66 and the pressing rod 68. The pressing rod 68 is horizontally slidably arranged in the through groove formed in the guiding plate 61. The pressing mechanism 69 is in extrusion cooperation with the pressing rod 68. The upper end of the pressing mechanism 69 is installed at the lower end position of the conveying member 41.

[0051] During the actual operation process, after the foamy floating slag is formed (the microbubbles rising will stick to the dye particles, fibers, and colloidal dirt in the water and carry them to the water surface), the electric slider 5 drives the conveying module 4, the lower guiding plate 61, the slag scraping filter screen 65, and the pushing plate 67 to move horizontally to the left. The foam floating slag is fished up horizontally and longitudinally through the slag scraping filter screen 65 and the pushing plate 67. When the conveying module 4 moves to the leftmost side, the floating slag fishing is completed at this time. The lower end of the lifting module 7 is engaged with the towing head 62, and the guiding plate 61 is driven to rise by the lifting module 7. During the rising process, the pressing rod 68 is pushed to move to the left by the extrusion of the pressing mechanism 69, so as to drive the pushing plate 67 to move to the left. The synchronously moving scraping plate 66 pushes and cleans the floating slag on the slag scraping filter screen 65 to the left. When it rises to the highest position, the longitudinal position of the pushing plate 67 is unlocked at this time. Subsequently, the air is conveyed to the distribution cavity 611 by the energized pump body 421 and blown out from the air hole, so as to blow and clean the floating slag on the pushing plate 67.

[0052] Refer to Figure 10As shown, the pushing plate 67 includes a movable plate 671, a filter net 672, a wind blade plate 673, sliding columns 674, guiding grooves 675, sliding heads 676, built-in grooves 677, and triangular blocks 678. An opening groove is formed inside the movable plate 671. The left end of the opening groove is provided with the filter net 672, and the right end of the opening groove is provided with the wind blade plate 673 with an inclined structure. The sliding columns 674 are installed at the lower end of the movable plate 671, and the sliding columns 674 are slidably arranged in the guiding grooves 675 formed in the connecting frame 64. The left end of the guiding groove 675 is of a flared structure. The sliding heads 676 are installed at the upper end of the scraping plate 66, and the sliding heads 676 are slidably arranged up and down in the sliding grooves formed at the lower end of the movable plate 671, and there is an elastic connection between the sliding grooves and the sliding heads 676. Built-in grooves 677 are formed in the upper side wall of the movable plate 671. An elastic layer is provided at the lower end of the built-in grooves 677. The triangular blocks 678 are installed at the lower end of the left side wall of the movable plate 671.

[0053] Referring to Figure 10 As shown, the extrusion rod 68 includes an extrusion piece 681, a limiting plate 682, and a movable block 683. The extrusion piece 681 is horizontally slidably arranged in the through groove formed in the guiding plate 61, and there is an elastic connection between the extrusion piece 681 and the through groove. The limiting plate 682 is installed at the right end position of the extrusion piece 681. The right end face of the extrusion piece 681 is of a chamfered structure. The movable block 683 is installed at the left end face of the extrusion piece 681, and the movable block 683 is slidably arranged up and down in the built-in grooves 677, and there is an elastic connection between the built-in grooves 677 and the movable block 683.

[0054] Referring to Figure 9 As shown, the extrusion mechanism 69 includes an extrusion block 691 and a linkage rod 692. The extrusion block 691 is installed at the lower end position of the conveying piece 41. The linkage rod 692 is horizontally slidably arranged in the horizontal groove formed at the upper end of the extrusion block 691, and there is an elastic connection between the linkage rod 692 and the horizontal groove. The right end of the linkage rod 692 is in extrusion cooperation with the insulating layer at the lower end of the conductive piece 424.

[0055] During the actual slag scraping process, the electric slider 5 drives the conveying module 4, the lower guiding plate 61, the slag scraping filter screen 65, and the pushing plate 67 to move horizontally to the left. The filter screen 672 on the movable plate 671 longitudinally scoops up the foam scum. When the conveying module 4 moves to the leftmost side, the scum scooping is completed. The lower end of the lifting module 7 is engaged with the towing head 62, and the guiding plate 61 is driven to rise by the lifting module 7. During the rising process, the right end of the squeezing member 681 squeezes the inclined surface position of the squeezing block 691, causing the squeezing member 681 to move to the left, thereby driving the movable plate 671 (temporarily locked at the current height) and the scraping plate 66 to move synchronously. The floating slag on the slag scraping filter screen 65 is pushed and cleaned to the left by the scraping plate 66. When the guiding plate 61 rises to the highest position, the height of the slag scraping filter screen 65 is flush with the inner bottom height of the storage frame 81. The filter screen 672 moves to the leftmost side and contacts the cleaning bristles around the lightweight shaft 433. The height of the movable plate 671 is unlocked, and the pump body 421 is powered on. After being powered on, the pump body 421 distributes air to the air distribution chamber 611 and the shunt chamber 45. The air in the shunt chamber 45 drives the lightweight shaft 433 and the cleaning bristles to rotate through the fan blade 432 when passing through the cleaning mechanism 43, thereby cleaning the filter screen 672. The air in the air distribution chamber 611 blows out from the air holes. The blown air passes through the air vane plate 673 and the filter screen 672 in sequence. Since the air vane plate 673 is composed of plate structures with different inclination degrees, it forms an up-and-down shaking when the wind passes through, causing the movable plate 671 and the filter screen 672 to shake synchronously. Through the horizontally rotating cleaning bristles, the up-and-down shaking filter screen 672, and the air blowing the filter screen 672, the floating slag on the filter screen 672 is further cleaned.

[0056] Refer to Figure 2 As shown, the lifting module 7 includes an electric push rod 71. The upper end of the electric push rod 71 is installed on the upper left side of the air flotation cylinder 1 through a connecting seat, and a hook 72 is installed at the extending end of the electric push rod 71.

[0057] During the actual operation process, when the conveying module 4 moves to the leftmost side, the scum scooping is completed. The hook 72 at the lower end of the electric push rod 71 is engaged with the towing head 62, and the guiding plate 61 is driven to rise by the electric push rod 71.

[0058] Refer to Figure 2 As shown, the collection module 8 includes a storage frame 81. The storage frame 81 is installed on the left side of the air flotation cylinder 1. A blanking port is opened at the lower end of the storage frame 81. The blanking port is connected to the upper end of the connecting frame 82. A collection frame 83 is slidably arranged inside the connecting frame 82. The feeding port opened at the upper end of the collection frame 83 corresponds to the position of the blanking port.

[0059] During the actual collection process, the scum on the slag scraping filter screen 65 and the filter screen 672 is blown onto the blanking port through pneumatic conveying and mechanical operations and finally enters the collection box 83 for centralized collection. The scum in the collection box 83 is cleared regularly.

[0060] Steps for treating fiber dyeing sewage:

[0061] 1. Pretreatment: The sewage is preliminarily filtered to filter out the fiber debris in the sewage.

[0062] 2. Air flotation and scum collection: The filtered sewage is transported to the air flotation cylinder 1 through the inlet. After the quantitative transportation is completed, microbubbles are released into the sewage through the dissolved air module 2, and with the help of the rotation of the eddy current generator 3, the bubbles are boosted to rise, carrying the pollutants to float to the water surface to form foamy scum. The scum on the water surface is scraped by the scum scraping module 6 until it moves to the leftmost side. At this time, a temporary assembly is formed between the lifting module 7 and the scum scraping module 6. The lifting module 7 rises to drive the scum scraping module 6 to rise, and the scum on the scum scraping module 6 is blown into the collection module 8.

[0063] 3. Oxidative decomposition: The sewage is transported to the next cylinder, ozone is injected into the sewage, and the cylinder is filled with honeycomb ceramic blocks with iron powder coated on the surface for oxidative decomposition operations.

[0064] 4. Salt-tolerant biological treatment: The sewage after oxidative decomposition is transported to the next reactor, filled with modified polyethylene fillers, and inoculated with halophilic bacteria to degrade organic matter.

[0065] 5. Advanced treatment: The sewage is further filtered through the reverse osmosis membrane module, and salt crystals are obtained by evaporation heating.
