Description

Technical Field

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

[0002] Cotton dyeing and printing wastewater treatment equipment is used to treat wastewater generated during the cotton dyeing and printing process. The dyes, auxiliaries, and other chemicals used in the cotton dyeing and printing process result in wastewater containing organic matter, pigments, suspended solids, and other pollutants. Therefore, this wastewater must be treated to reduce its environmental impact and meet discharge standards.

[0003] A wastewater treatment device for printing and dyeing, with patent publication number CN214031777U, includes a treatment box, a base, and a cover. The treatment box is fixedly connected to the top of the base, and the cover is fixedly installed on the top of the treatment box. It also includes a rotating shaft. The top of the cover has a strip-shaped hole for the rotating shaft to move. The bottom end of the rotating shaft extends through the strip-shaped hole into the interior of the treatment box, and the top end of the rotating shaft is located above the strip-shaped hole. A gear is fixedly connected to the shaft of the rotating shaft above the strip-shaped hole. A rack parallel to the strip-shaped hole is fixedly connected to the top of the cover near the rear of the strip-shaped hole, and the gear meshes with the rack. Multiple stirring mechanisms are provided inside the treatment box on the shaft of the rotating shaft.

[0004] The aforementioned existing patents and traditional equipment have the following problems: Traditional equipment usually mixes wastewater by adding chemicals and stirring. However, cotton lint impurities in dyeing wastewater need to be filtered through a filter screen. The filter screen of traditional equipment usually adopts a fixed structure, which makes it impossible to filter cotton lint impurities floating in the wastewater quickly. Its treatment efficiency is low and the effect is poor, thus affecting the subsequent wastewater treatment work. Summary of the Invention

[0009] Preferably, the right-angle swing frame is integrated with the main swing frame, and the connecting frame and the pushing frame are parallel to each other.

[0010] Preferably, both the first fixed slide rail and the second fixed slide rail are inclined, and the inclination angles of the two are the same.

[0011] Preferably, the flipping mechanism includes a fixed hinge, a movable slide rail, a slide bar, a swing arm, a connecting plate, and a positioning assembly.

[0012] Preferably, the positioning assembly includes a fixed support plate, a first rotating component, a steering block, a second rotating component, and a spring.

[0016] The beneficial effects of this invention are:

[0017] This invention incorporates a pushing and dispersing device. Driven by a cyclic pushing mechanism, the main pushing frame repeatedly moves the filter screen back and forth and up and down, effectively filtering and collecting lint and impurities from the wastewater inside the treatment tank, thereby improving the efficiency of wastewater treatment.

[0018] Furthermore, driven by motor one, the cyclic pushing mechanism rotates the bogie to drive the main swing frame. With the synchronous swing of right-angle swing frame one, connecting frame, pushing frame, and right-angle swing frame two, the main pushing frame can be pushed forward, backward, up, and down, so that the filter screen can move synchronously, improving the filtration and collection effect of cotton wool impurities in sewage.

[0019] Furthermore, the flipping mechanism facilitates the cleaning and replacement of the filter screen. Pulling the filter screen causes the swing arm to flip up along with it, while the slide bar slides within the movable slide rail, causing the movable slide rail to extend upwards. Simultaneously, the fixed hinge flips up, allowing the filter screen to flip up quickly. This eliminates the need for manual insertion into the processing chamber to clean or replace the filter screen, making it more convenient and efficient.

[0020] Furthermore, the positioning component can position the flipped-up filter screen, and the spring elastic force can hold the swing arm in place, making it convenient to clean and replace the flipped-up filter screen.

[0021] Furthermore, the set-up dispersing mechanism, driven by motor two, can rotate the bogie frame, synchronously driving dispersing blade one and dispersing blade two to turn. At the same time, since the fixed cylinder is fixed, dispersing blade one and dispersing blade two slide in the adjusting groove one and adjusting groove two through adjusting frame one and adjusting frame two and then rotate and flip over, thereby effectively dispersing the sewage at the bottom of the treatment tank, preventing cotton lint and impurities from settling, and improving the filtration and collection efficiency of the filter screen.

[0022] Furthermore, both the first and second dispersing blades are equipped with two blades, which are arranged vertically symmetrically. The blades of the first and second dispersing blades are also arranged vertically symmetrically from top to bottom. At the same time, the grooves of the first and second adjusting grooves are arranged in opposite directions symmetrically from top to bottom, which allows the first and second dispersing blades to rotate in different directions, thereby improving the dispersing efficiency.

Detailed Implementation

[0032] To further explain the technical solution of the present invention, a detailed description is provided below through specific embodiments.

[0033] like Figure 1 As shown, the present invention provides a cotton dyeing wastewater treatment device, including a treatment tank 1, support legs 2, filter screens 3, and a pushing and dispersing device 4. The support legs 2 are installed at the bottom of the treatment tank 1, and multiple sets of filter screens 3 are arranged inside the treatment tank 1. The pushing and dispersing device 4 is installed on the treatment tank 1 and connected to multiple sets of filter screens 3. In this embodiment, three sets of filter screens 3 are provided, which can effectively filter and collect cotton lint impurities in the wastewater inside the treatment tank 1.

[0034] like Figure 2As shown, in this embodiment, the pushing and dispersing device 4 includes a circulating pushing mechanism 41, a main pushing frame 42, a first auxiliary support 43, a second auxiliary support 44, a flipping mechanism 45, a third auxiliary support 46, and a dispersing mechanism 47. The circulating pushing mechanism 41 is installed on the processing box 1 and connected to the main pushing frame 42 at the bottom. Multiple sets of first auxiliary supports 43 and second auxiliary supports 44 are installed at the bottom of the main pushing frame 42. The number of first auxiliary supports 43, second auxiliary supports 44, and flipping mechanism 45 is the same as the number of filter screens 3 installed, which facilitates the installation of filter screens 3. Filter screens 3 are installed on second auxiliary supports 43 and second auxiliary supports 44 through flipping mechanism 45. The third auxiliary support 46 extends laterally from the middle of the main pushing frame 42. The bottom of the third auxiliary support 46 is equipped with a dispersing mechanism 47 that extends to the bottom of filter screens 3. After the dispersing mechanism 47 is placed at the bottom of filter screens 3, it can disperse the cotton-like impurities at the bottom of the sewage, reduce sedimentation, and improve the filtration and collection efficiency of filter screens 3.

[0035] In this embodiment, three sets of secondary support 1 43, secondary support 2 44 and flipping mechanism 45 are provided, and the number of secondary support 1 43, secondary support 2 44 and flipping mechanism 45 corresponds to the number of filter screens 3 installed. They can simultaneously drive three sets of filter screens 3 to perform filtration and collection work, thereby improving the efficiency of sewage treatment.

[0036] Specifically, the push mechanism 41 pushes the filter screen 3, which is fixed by the flipping mechanism 45, to move up and down and back and forth, thereby efficiently filtering and collecting cotton wool impurities in the sewage. At the same time, the dispersing mechanism 47 also moves up and down and back and forth synchronously with the push mechanism 42. Furthermore, the dispersing blades of the dispersing mechanism 47 can rotate and rotate synchronously, effectively dispersing the bottom of the sewage, preventing cotton wool from settling and improving the filtration and collection efficiency of the filter screen 3.

[0037] like Figure 3As shown, in this embodiment, the cyclic pushing mechanism 41 includes an outer frame 411 fixedly installed on the rear side of the processing box 1. The outer frame 411 is fixedly connected to the rear end and both sides of the processing box 1 to ensure the stability of the support. A motor 412 is installed on the rear end of the outer frame 411. The output end of the motor 412 is connected to a bogie 413 set inside the outer frame 411. The other end of the bogie 413 is rotatably connected to the main swing frame 414. The other end of the main swing frame 414 is rotatably connected to the right angle of the first right-angle swing frame 415 and one end of the connecting frame 416 through a shaft. The other end of the connecting frame 416 is coaxially connected to the right angle of the second right-angle swing frame 418. One corner of the first right-angle swing frame 415 is rotatably connected to a rod on the top of the pushing main frame 42, and the other corner is connected to one end of the pushing frame 417. Rotary connection, the other end of the push frame 417 is rotatably connected to one corner of the right-angle swing frame 418, and the other corner of the right-angle swing frame 418 is rotatably connected to another frame rod on the top of the push main frame 42. It should be noted that there are two frame rods on the top of the push main frame 42, which are rotatably connected to one corner of the right-angle swing frame 415 and one corner of the right-angle swing frame 418 respectively. The rear end of the shaft rod coaxially connected to the right angle of the main swing frame 414 and the right-angle swing frame 415 at the right angle, and the rear end of the shaft rod coaxially connected to the right angle of the connecting frame 416 and the right-angle swing frame 418 at the right angle are respectively equipped with pulley 419 and pulley 4110. The pulley 419 and pulley 4110 are slidably connected to the inner side of the fixed slide rail 4111 and the fixed slide rail 4112 installed on the inner rear end of the outer frame 411 respectively.

[0038] Among them, the right-angle swing frame 415 and the main swing frame 414 are integrated swing. The main swing frame 414 swings synchronously and drives the right-angle swing frame 415 to swing. The connecting frame 416 does not swing. The connecting frame 416 performs a driven pushing operation. The connecting frame 416 and the pushing frame 417 are parallel to each other. The connecting frame 416 and the pushing frame 417 can synchronously drive the right-angle swing frame 418 to swing, so that the pushing main frame 42 swings synchronously.

[0039] Among them, fixed slide rail 1 4111 and fixed slide rail 2 4112 are both inclined and have the same inclination angle, so that right-angle swing frame 1 415 and right-angle swing frame 2 418 maintain a certain movement trajectory when swinging, and at the same time provide a certain stable support, so that the push main frame 42 can swing up and down and back and forth stably.

[0040] Specifically, after motor 412 starts working, it drives bogie 413 to rotate. Then, the rotation of bogie 413 drives main swing frame 414 to swing back and forth. Then, main swing frame 414 drives right-angle swing frame 415 to swing. At the same time, the connection of connecting frame 416 and push frame 417 makes right-angle swing frame 418 and right-angle swing frame 415 swing in the same way. And the rear ends of both slide in fixed slide rail 4111 and fixed slide rail 4112 respectively through pulley 419 and pulley 4110. Then, right-angle swing frame 418 and right-angle swing frame 415 drive push frame 42 to push up and down and back and forth.

[0041] like Figure 4 As shown, in this embodiment, the flipping mechanism 45 includes a fixed hinge 451, a movable slide rail 452, a slide bar 453, a swing arm 454, a connecting plate 455, and a positioning component 456. The fixed hinge 451 is mounted on the second auxiliary bracket 44, and the bottom of the fixed hinge 451 is connected to the movable slide rail 452. The slide bar 453 is slidably connected on the movable slide rail 452. The slide bar 453 is connected to the rear part of the frame of the filter screen 3. The swing arm 454 is mounted on the first auxiliary bracket 43 through the positioning component 456, and one bottom end of the swing arm 454 is rotatably connected to the connecting plate 455. The connecting plate 455 is connected to one side of the rear bottom of the frame of the filter screen 3.

[0042] Specifically, when the filter screen 3 is pulled, the slide bar 453 slides within the movable slide rail 452, and the movable slide rail 452 flips with the fixed hinge 451, causing the slide bar 453 to slide and flip up, simultaneously flipping up the filter screen 3. The swing arm 454 swings as the filter screen 3 flips up and is positioned by the positioning component 456, making it less likely for the filter screen 3 to fall off after flipping up, facilitating cleaning and replacement.

[0043] like Figure 5 As shown, in this embodiment, the positioning component 456 includes a fixed support plate 4561, a first rotating component 4562, a steering block 4563, a second rotating component 4564, and a spring 4565. The fixed support plate 4561 is mounted on the first auxiliary bracket 43. The two ends of the fixed support plate 4561 are rotatably connected to the first rotating component 4562 and the steering block 4563 respectively through shafts. The steering block 4563 is coaxially connected to the upper end of the swing arm 454 so that the two swing synchronously. The second rotating component 4564 is rotatably connected to the end of the steering block 4563 through a shaft. The second rotating component 4564 and the first rotating component 4562 are elastically connected through the spring 4565.

[0044] Specifically, when the swing arm 454 is in the direction of the rotation block 4563, the rotating part 4564 is pushed upward. At this time, the spring 4565 is in the open state, so that the rotating part 4562 and the rotating part 4564 are held together by the spring 4565, making it difficult for the swing arm 454 to move. When the filter screen 3 is flipped up by force, the swing arm 454 is tilted and flipped up by force. During the flipping process, the spring 4565 is compressed. After the filter screen 3 is flipped up to the appropriate position, the swing arm 454 turns the rotation block 4563 downward. At the same time, the rotating part 4564 and the rotating part 4562 are again held together by the elastic force of the spring 4565, so that the filter screen 3 can be positioned.

[0045] like Figure 6-7 As shown, in this embodiment, the disintegration mechanism 47 includes a support column 471 fixedly installed at the bottom of the sub-support 3 46 and a motor 2 472 installed at the upper end of the sub-support 3 46. The bottom of the support column 471 is connected to a fixed cylinder 473. The fixed cylinder 473 surrounds the bogie frame 474 on the outside, and the two are rotatably connected at their upper and lower ends. A transmission rod 475 is provided inside the support column 471. The top of the transmission rod 475 is connected to the output end of the motor 2 472, and the bottom passes through the top of the bogie frame 474 and through the fixed cylinder 473 before connecting to the bottom center of the bogie frame 474. The upper and lower parts of both sides of the bogie frame 474 are respectively The bogie frame 474 is equipped with a first dispersing blade 476 and a second dispersing blade 477. Both the first dispersing blade 476 and the second dispersing blade 477 have a protruding rod in the middle of the side facing the bogie frame 474. The protruding rods of the first dispersing blade 476 and the second dispersing blade 477 pass through the bogie frame 474 and are respectively connected to the first adjustment frame 478 and the second adjustment frame 479. The first adjustment frame 478 and the second adjustment frame 479 are respectively connected to the first movable ball 4710 and the second movable ball 4711. The first movable ball 4710 and the second movable ball 4711 are slidably connected to the first adjustment groove 4712 and the second adjustment groove 4713 provided on the fixed cylinder 473.

[0046] Both the first dispersing blade 476 and the second dispersing blade 477 are equipped with two blades, which are arranged vertically symmetrically. Furthermore, the blades of the first dispersing blade 476 and the second dispersing blade 477 are arranged vertically symmetrically from top to bottom. At the same time, the grooves of the first adjusting groove 4712 and the second adjusting groove 4713 are arranged symmetrically in opposite directions from top to bottom. The two blades of the first dispersing blade 476 and the two blades of the second dispersing blade 477 can rotate in different directions, thereby improving the dispersing efficiency.

[0047] Specifically, driven by motor 472, the steering frame 474 rotates via transmission rod 475, synchronously driving the first dispersing blade 476 and the second dispersing blade 477 to turn and stir and disperse the sewage. Meanwhile, since the fixed cylinder 473 is fixed, it is equipped with symmetrical adjustment grooves 4712 and 4713. The first dispersing blade 476 and the second dispersing blade 477 rotate and flip after sliding in the adjustment grooves 4712 and 4713 via the movable balls 4710 and 4711 on the adjustment frame 478 and the adjustment frame 479, thereby effectively dispersing the sewage at the bottom of the treatment tank 1, preventing the sedimentation of lint and impurities, and improving the filtration and collection efficiency of the filter screen 3.

[0048] It should be noted that this equipment is for wastewater pretreatment. Wastewater discharged from the processing workshop is collected and pretreated in this equipment before entering the equalization tank for homogenization and flow equalization. It is then pumped to a high-temperature cooling tower for air cooling. The effluent flows by gravity to the hydrolysis acidification tank, which is equipped with combined packing material to provide a growth environment for anaerobic bacteria. After passing through the hydrolysis acidification tank, the wastewater enters the anoxic tank and contact oxidation tank. Through sludge and nitrification liquid recirculation, the nitrification-denitrification process is completed to remove COD and total nitrogen. Sufficient oxygen is provided by aeration, and aerobic microorganisms absorb organic matter from the wastewater. The treated water that meets the standards is discharged. The remaining sludge in the system enters the sludge thickening tank for thickening, then is pumped into a filter press for dewatering. The filtrate is returned to the equalization tank, and finally, the sludge cake undergoes sanitary treatment. The specific treatment process is as follows: Figure 8 As shown.

[0049] This invention provides a cotton dyeing wastewater treatment device. By incorporating a pushing and dispersing device 4, driven by a circulating pushing mechanism 41, the main pushing frame 42 repeatedly moves the filter screen 3 back and forth and up and down, effectively filtering and collecting cotton lint and impurities from the wastewater inside the treatment tank 1, thus improving wastewater treatment efficiency. Driven by a motor 43, the circulating pushing mechanism 41 rotates, driving the main swing frame 414. With the synchronized swing of the right-angle swing frame 415, connecting frame 416, pushing frame 417, and right-angle swing frame 418, the main pushing frame 42 can perform forward, backward, up, and down pushing operations, allowing the filter screen 3 to move synchronously, further improving the filtration and collection effect of cotton lint and impurities in the wastewater.

[0050] This invention provides a wastewater treatment device for cotton dyeing and printing. The flipping mechanism 45 facilitates the cleaning and replacement of the filter screen 3. When the filter screen 3 is pulled, the swing arm 454 flips up with the filter screen 3. At the same time, the slide bar 453 slides in the movable slide rail 452, causing the movable slide rail 452 to extend upward. Simultaneously, the fixed hinge 451 flips, allowing the filter screen 3 to flip up quickly. This eliminates the need for manual insertion into the treatment chamber 1 to clean and replace the filter screen 3, making it more convenient and efficient. The positioning component 456 can position the flipped filter screen 3. The elastic force of the spring 4565 can hold the swing arm 454 in place, thus facilitating the cleaning and replacement of the flipped filter screen 3.

[0051] The disintegration mechanism 47, driven by motor 472, can rotate the bogie frame 474, synchronously driving the disintegration blades 476 and 477 to rotate. Simultaneously, since the fixed cylinder 473 is fixed, the disintegration blades 476 and 477 rotate and flip over after sliding within the adjustment slots 4712 and 4713 via the movable balls 4710 and 4711 on the adjustment frames 478 and 479, respectively. This effectively cleans the processing box. 1. The wastewater at the bottom is dispersed to prevent cotton wool and impurities from settling and to improve the filtration and collection efficiency of the filter screen 3. Both the dispersing blade 1 (476) and the dispersing blade 2 (477) are equipped with two blades, which are arranged vertically symmetrically. The blades of the two blades are also arranged vertically symmetrically from top to bottom. At the same time, the channels of the adjusting groove 1 (4712) and the adjusting groove 2 (4713) are arranged in opposite directions symmetrically, which allows the dispersing blade 1 (476) and the dispersing blade 2 (477) to rotate in different directions, thereby improving the dispersion efficiency.
