Description

Technical Field

[0001] This invention relates to the field of wastewater purification equipment, specifically to a wastewater purification device and method for blanket printing and dyeing. Background Technology

[0002] Wastewater purification refers to the process of removing or transforming pollutants in wastewater through physical, chemical, biological, or integrated technical means to make it meet discharge standards or reuse requirements. Its core objectives are to protect the water environment, ensure ecological security, and realize the recycling of water resources.

[0003] Chinese patent CN109704489B discloses an integrated wastewater purification machine for textile printing and dyeing, including a chassis and a wastewater inlet located on the top of the chassis, as well as a filtration unit, a deodorization unit, a buffer unit, a drive unit, a biological filter tank, and a controller. The controller is used to control the operation of the integrated wastewater purification machine. The filtration unit, deodorization unit, and buffer unit are arranged sequentially from top to bottom inside the chassis.

[0004] In the aforementioned patents and prior art, when purifying wastewater from blanket printing and dyeing, the first step is to filter and clean the flocculent fibers in the wastewater. However, the flocculent fibers are very easy to clog the filter screen during filtration. Furthermore, because the flocculent fibers are long and soft, they are difficult to remove from the filter screen, which seriously affects the purification efficiency of the wastewater from blanket printing and dyeing. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a wastewater purification device and method for blanket printing and dyeing wastewater.

[0006] A wastewater purification device for blanket printing and dyeing includes a wastewater purification chamber, a pollutant collection plate installed inside the wastewater purification chamber, a fiber filtration mechanism installed inside the wastewater purification chamber, a drive mechanism installed on the top of the pollutant collection plate, a sealing baffle slidably installed inside the wastewater purification chamber, a transmission rack connected to the outside of the sealing baffle, and connecting pipes provided at both ends of the wastewater purification chamber.

[0008] The wastewater purification chamber is connected to the outside via a connecting pipe. The fiber filtration mechanism can intercept and filter the flocculent fibers in the carpet dyeing wastewater passing through the wastewater purification chamber. The drive mechanism can drive the fiber filtration mechanism to move the flocculent fibers filtered from the outside to the inside of the pollutant collection plate. When the fiber filtration mechanism moves the flocculent fibers to the inside of the pollutant collection plate, it can drive the sealing baffle to move inside the wastewater purification chamber through the transmission rack to block the connecting pipe.

[0013] When the drive mechanism moves the lifting connecting cable upward, it can first move the sliding transmission block upward inside the base cleaning plate. When the sliding transmission block moves upward inside the base cleaning plate, it can drive the contaminant baffle to rotate counterclockwise through the transmission connecting rod. After the contaminant baffle is in contact with the base cleaning plate, the lifting connecting cable can move upward and drive the base cleaning plate upward through the sliding transmission block. The interior of the base cleaning plate has an inclined structure. The lower side of the interior of the base cleaning plate is the side close to the contaminant collection plate, and the higher side of the interior of the base cleaning plate is in contact with the contaminant baffle.

[0020] A wastewater purification method using the aforementioned wastewater purification device for blanket printing and dyeing.

[0021] Compared with the prior art, the present invention provides a wastewater purification device and method for blanket printing and dyeing wastewater, which has the following beneficial effects:

[0022] 1. In this type of wastewater purification device for blanket printing and dyeing, when excessive flocculent fibers accumulate on the teeth of the filter base, the drive mechanism can move the base cleaning plate upward along the teeth on the filter base. As the base cleaning plate moves upward, it can move the flocculent fibers on the teeth of the filter base. After the base cleaning plate separates from the teeth, the flocculent fibers remain inside the base cleaning plate. As the base cleaning plate continues to move upward, it slides along the inclined structure inside the base cleaning plate into the interior of the pollutant collection plate. By quickly cleaning the accumulated flocculent fibers on the fiber filtration mechanism, it prevents excessive accumulation of flocculent fibers on the fiber filtration mechanism from affecting the purification efficiency of the wastewater for blanket printing and dyeing.

[0023] 2. In this type of wastewater purification device for blanket printing and dyeing, the lifting connecting cable can drive the first steering roller, the second steering roller, and the transverse steering roller to rotate synchronously when passing through them. When the second steering roller rotates, it can drive the transmission gear to rotate synchronously. When the transmission gear rotates, it can drive the transmission rack to move at the top of the wastewater purification chamber. When the transmission rack moves, it can drive the sealing baffle to move inside the wastewater purification chamber. When the sealing baffle is in contact with the connecting pipe, it can block the connecting pipe and prevent the wastewater from continuing to flow inside the wastewater purification chamber, thereby ensuring the purification quality of the wastewater from the blanket printing and dyeing by the fiber filtration mechanism.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a wastewater purification device and wastewater purification method for blanket printing and dyeing.

[0039] Example 1:

[0040] Please see Figure 1 - Figure 12 A wastewater purification device for blanket printing and dyeing includes a wastewater purification chamber 1, a pollutant collection plate 2 installed inside the wastewater purification chamber 1, a fiber filter mechanism 3 installed inside the wastewater purification chamber 1, a drive mechanism 4 installed on the top of the pollutant collection plate 2, a sealing baffle 5 slidably installed inside the wastewater purification chamber 1, a transmission rack 6 connected to the outside of the sealing baffle 5, and connecting pipes 7 provided at both ends of the wastewater purification chamber 1.

[0041] The outside of the fiber filter mechanism 3 is connected to the center of the drive mechanism 4. The sealing baffle 5 is connected to the outside of the fiber filter mechanism 3 through the external transmission rack 6. Fiber filter mechanisms 3 are provided on both sides of the pollutant collection plate 2. The two sides of the pollutant collection plate 2 that contact the fiber filter mechanism 3 are inclined.

[0042] The interior of the wastewater purification chamber 1 is connected to the outside through the connecting pipe 7. The fiber filtration mechanism 3 can intercept and filter the flocculent fibers in the carpet dyeing wastewater passing through the wastewater purification chamber 1. The drive mechanism 4 can drive the fiber filtration mechanism 3 to move the flocculent fibers filtered from the outside to the inside of the pollutant collection plate 2. When the fiber filtration mechanism 3 moves the flocculent fibers to the inside of the pollutant collection plate 2, it can drive the sealing baffle 5 to move inside the wastewater purification chamber 1 through the transmission rack 6 to block the connecting pipe 7.

[0043] During operation, the connecting pipes 7 at both ends of the wastewater purification chamber 1 are connected to the external pipes, allowing the wastewater from the blanket dyeing and printing process to pass through the interior of the wastewater purification chamber 1. As the wastewater passes through the interior of the wastewater purification chamber 1, the fiber filtration mechanism 3 intercepts and filters the flocculent fibers in the wastewater. After a certain amount of flocculent fibers accumulate inside the fiber filtration mechanism 3, the drive mechanism 4 moves the externally filtered flocculent fibers to the interior of the pollutant collection plate 2. When the fiber filtration mechanism 3 moves the flocculent fibers to the interior of the pollutant collection plate 2, the transmission rack 6 drives the sealing baffle 5 to move inside the wastewater purification chamber 1 to block the connecting pipes 7, preventing the wastewater from continuing to flow inside the wastewater purification chamber 1. Thus, during operation, the drive mechanism 4 can quickly clean the accumulated flocculent fibers on the fiber filtration mechanism 3, preventing excessive accumulation of flocculent fibers on the fiber filtration mechanism 3 from affecting the purification efficiency of the wastewater from the blanket dyeing and printing process.

[0044] Example 2:

[0045] The difference from the above embodiments is that, please refer to [link / reference needed]. Figure 1 - Figure 12 The fiber filtration mechanism 3 includes a filter base 31, a base cleaning plate 32 slidably mounted on the outside of the filter base 31, a sliding transmission block 33 slidably mounted on the top of the base cleaning plate 32, a transmission connecting rod 34 connected to the outside of the sliding transmission block 33, a contaminant baffle 35 mounted on the outside of the base cleaning plate 32, a lifting connecting cable 36 connected to the top of the sliding transmission block 33, a first steering roller 37 mounted on the outside of the wastewater purification chamber 1, a second steering roller 38 mounted on the outside of the wastewater purification chamber 1, a transmission gear 39 connected to the outside of the second steering roller 38, and a transverse steering roller 310 mounted on the outside of the wastewater purification chamber 1.

[0046] Multiple teeth are evenly arranged on the top of the filter base 31. The base cleaning plate 32 is slidably installed on the outside of the teeth on the filter base 31. The base cleaning plate 32 is connected to the drive mechanism 4 through the sliding transmission block 33 and the lifting connecting cable 36.

[0047] The filter base 31 can intercept and filter the flocculent fibers in the wastewater from the carpet printing and dyeing process passing through the wastewater purification chamber 1 through the teeth set at the top. The drive mechanism 4 can drive the base cleaning plate 32 to move upward along the teeth on the filter base 31. When the base cleaning plate 32 moves upward, it can clean the flocculent fibers on the teeth of the filter base 31 and move them into the interior of the pollutant collection plate 2.

[0048] One end of the contaminant baffle 35 is rotatably connected to the transmission connecting rod 34, and the other end of the contaminant baffle 35 is rotatably connected to the base cleaning plate 32. The sliding transmission block 33 and the contaminant baffle 35 are movably connected through the transmission connecting rod 34. The outside of the sliding transmission block 33 is slidably connected to the base cleaning plate 32, and the top of the sliding transmission block 33 is connected to the drive mechanism 4 through the lifting connecting cable 36.

[0049] When the drive mechanism 4 drives the lifting connecting cable 36 to move upward, it can first drive the sliding transmission block 33 to move upward inside the base cleaning plate 32. When the sliding transmission block 33 moves upward inside the base cleaning plate 32, it can drive the contaminant baffle 35 to rotate counterclockwise through the transmission connecting rod 34. After the contaminant baffle 35 is in contact with the base cleaning plate 32, the lifting connecting cable 36 can move upward and drive the base cleaning plate 32 to move upward through the sliding transmission block 33. The interior of the base cleaning plate 32 has an inclined structure. The lower side of the interior of the base cleaning plate 32 is the side close to the contaminant collection plate 2, and the higher side of the interior of the base cleaning plate 32 is in contact with the contaminant baffle 35.

[0050] One end of the lifting connecting cable 36 is connected to the top of the sliding transmission block 33, and the other end of the lifting connecting cable 36 passes through the first steering roller 37, the second steering roller 38 and the transverse steering roller 310 and is connected to the drive mechanism 4. The outside of the second steering roller 38 meshes with the outside of the transmission rack 6 through the transmission gear 39.

[0051] The first steering roller 37, the second steering roller 38, and the lateral steering roller 310 can adjust the direction of the lifting connecting cable 36. The drive mechanism 4 can wind up the lifting connecting cable 36. When the lifting connecting cable 36 passes the first steering roller 37, the second steering roller 38, and the lateral steering roller 310, it can drive the first steering roller 37, the second steering roller 38, and the lateral steering roller 310 to rotate synchronously. When the second steering roller 38 rotates, it can drive the transmission gear 39 to rotate synchronously. When the transmission gear 39 rotates, it can drive the transmission rack 6 to move at the top of the wastewater purification chamber 1. When the transmission rack 6 moves, it can drive the sealing baffle 5 to move inside the wastewater purification chamber 1.

[0052] During operation, the filter base 31 can intercept and filter the flocculent fibers in the wastewater from the carpet dyeing and printing process passing through the wastewater purification chamber 1 via the top-mounted teeth. When too much flocculent fiber accumulates on the teeth of the filter base 31, the drive mechanism 4 can drive the base cleaning plate 32 to move upward along the teeth on the filter base 31. Specifically, when the drive mechanism 4 drives the lifting connecting cable 36 upward, it can first drive the sliding transmission block 33 to move upward inside the base cleaning plate 32. When the internal structure moves upward, it can drive the contaminant baffle 35 to rotate counterclockwise via the transmission connecting rod 34. After the contaminant baffle 35 is in contact with the base cleaning plate 32, the lifting connecting cable 36 moves upward, which can drive the base cleaning plate 32 to move upward via the sliding transmission block 33. When the base cleaning plate 32 moves upward, the flocculent fibers on the filter base 31 can move along the flocculent fibers on the filter base 31. After the base cleaning plate 32 separates from the flocculent fibers, the flocculent fibers remain inside the base cleaning plate 32, and the base cleaning plate 32... 2. As it continues to move upward, it slides along the inclined structure inside the base cleaning plate 32 into the interior of the pollutant collection plate 2. When the drive mechanism 4 pulls the lifting connecting cable 36 upward, the first steering roller 37, the second steering roller 38, and the transverse steering roller 310 can adjust the direction of the lifting connecting cable 36. When the lifting connecting cable 36 passes the first steering roller 37, the second steering roller 38, and the transverse steering roller 310, it can drive the first steering roller 37, the second steering roller 38, and the transverse steering roller 310 to rotate synchronously. When the second steering roller 38 rotates, it can drive the transmission gear 39 to rotate synchronously. When the transmission gear 39 rotates, it can drive the transmission rack 6 to move at the top of the wastewater purification chamber 1. When the transmission rack 6 moves, it can drive the sealing baffle 5 to move inside the wastewater purification chamber 1. When the sealing baffle 5 is in contact with the connecting pipe 7, the sealing baffle 5 can block the connecting pipe 7, preventing the carpet dyeing wastewater inside the wastewater purification chamber 1 from continuing to flow, thereby ensuring the purification quality of the carpet dyeing wastewater by the fiber filtration mechanism 3.

[0053] Example 3:

[0054] The difference from the above embodiments is that, please refer to [link / reference needed]. Figure 1 - Figure 12 The drive mechanism 4 includes a drive motor 41 and a lower mounting platform 44. The drive motor 41 is installed outside the wastewater purification chamber 1. A motor roller 42 is installed on the power end of the drive motor 41. A transmission belt 43 is installed outside the motor roller 42. The lower mounting platform 44 is installed on the top of the pollutant collection plate 2. An upper mounting platform 45 is installed on the top of the lower mounting platform 44. A threaded connecting shaft 46 is threaded inside the lower mounting platform 44. A roller mounting shaft 47 is slidably installed inside the threaded connecting shaft 46. A winding transmission roller 48 is connected to the top of the roller mounting shaft 47. A lifting buffer groove 49 is provided on the top of the pollutant collection plate 2.

[0055] The motor roller 42 and the winding drive roller 48 are connected by a drive belt 43. The drive motor 41 can drive the roller mounting shaft 47 to rotate through the transmission connection between the winding drive roller 48 and the motor roller 42. When the roller mounting shaft 47 rotates, it can drive the threaded connection shaft 46 to rotate synchronously.

[0056] The threaded connecting shaft 46 is externally connected to the lifting connecting cable 36 and externally connected to the lower mounting platform 44. When the threaded connecting shaft 46 rotates, it can pull the lifting connecting cable 36 and wind up the lifting connecting cable 36. When the threaded connecting shaft 46 rotates, it can move up and down inside the lower mounting platform 44. When the threaded connecting shaft 46 moves up and down, the bottom of the threaded connecting shaft 46 can move up and down inside the lifting buffer groove 49.

[0057] When the threaded connecting shaft 46 rotates clockwise, it can wind up the lifting connecting cable 36 and move downward inside the lifting buffer groove 49. When the threaded connecting shaft 46 rotates counterclockwise, it can unwind the lifting connecting cable 36 and move upward inside the lifting buffer groove 49.

[0058] During operation, the drive motor 41 drives the roller mounting shaft 47 to rotate via the transmission connection between the winding transmission roller 48 and the motor roller 42. When the roller mounting shaft 47 rotates, it drives the threaded connecting shaft 46 to rotate synchronously. When the threaded connecting shaft 46 rotates clockwise, it winds up the externally connected lifting connecting cable 36. While the threaded connecting shaft 46 winds up the lifting connecting cable 36, it drives the base cleaning plate 32 to clean the accumulated fibrous fibers on the outside of the filter base 31. Furthermore, when the threaded connecting shaft 46 rotates clockwise, it can connect with the lower mounting shaft 46... The threaded connection of mounting platform 44 moves downward. When the threaded connection shaft 46 moves downward, the bottom of the threaded connection shaft 46 can move downward inside the lifting buffer groove 49. When the threaded connection shaft 46 rotates counterclockwise, the threaded connection shaft 46 can cause the lifting connection cable 36 to unfold and move upward inside the lifting buffer groove 49. The rotation of the threaded connection shaft 46 can be used to wind up and loosen the lifting connection cable 36. The fiber filter mechanism 3 cleans the accumulated flocculent fibers on the outside, which can effectively prevent the excessive accumulation of flocculent fibers on the outside of the fiber filter mechanism 3 from affecting the purification efficiency of the wastewater from the printing and dyeing of blankets.

[0059] Example 4:

[0060] A method for purifying positioning wastewater from brake assembly processing, using a wastewater purification device for blanket dyeing and printing as described in Examples 1 to 3, includes the following steps:

[0061] During operation, the connecting pipes 7 at both ends of the wastewater purification chamber 1 are connected to the external pipes, so that the wastewater from the blanket printing and dyeing can pass through the interior of the wastewater purification chamber 1.

[0062] When the wastewater from the blanket printing and dyeing process passes through the interior of the wastewater purification chamber 1, the fiber filtration mechanism 3 can intercept and filter the flocculent fibers in the wastewater.

[0063] The drive mechanism 4 can drive the fiber filter mechanism 3 to move the externally filtered flocculent fibers into the interior of the pollutant collection plate 2;

[0064] When the fiber filtration mechanism 3 moves the flocculent fibers into the pollutant collection plate 2, it can drive the sealing baffle 5 to move inside the wastewater purification chamber 1 via the transmission rack 6 to block the connecting pipe 7.
