Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically a wastewater treatment device for textile printing and dyeing. Background Technology

[0002] Flotation tanks, especially dissolved air flotation tanks, play an important role in sewage treatment, reclaimed water reuse, and industrial wastewater treatment. By injecting air into the water, suspended solids, organic matter, and oil pollutants in the water float to the surface, thereby achieving solid-liquid separation and improving water quality. This technology is not only highly efficient in purification but also highly adaptable, has low operating costs, and is easy to maintain. It is of great significance for protecting water resources and reducing environmental pollution and is an indispensable "cleaner" in the modern environmental protection field.

[0003] A search revealed Chinese patent CN210367054U, which discloses a shallow air flotation machine. The machine includes a tank body with a scum cleaning device on its inner side. A balancing mechanism is located on one side of the scum cleaning device, and a scum collection device is located at the top of the balancing mechanism. A motor is located at one end of the scum collection device. A first scum-containing layer is located inside the scum collection device, and a rotating head is located inside the first scum-containing layer. A water pump is located at the end of the scum collection device furthest from the motor. A scum discharge pipe is located at the bottom of the water pump, and a scum discharge tank is located at the bottom of the scum discharge pipe. A current collection device is located inside the scum discharge tank, and a clear water tank is located around the scum discharge tank. This invention utilizes a rotating head for stable scum transmission, and the suction generated by the water pump driving the scum discharge pipe facilitates thorough cleaning of the scum within the scum collection device, preventing clogging. The scum cleaning device removes residual scum, resulting in a cleaner and more thorough cleaning process and improved cleaning efficiency. The above-mentioned patent has the following shortcomings: When the sludge hopper of the flotation tank is recycling the surface sludge, a lot of stains will stick to the outer wall of the sludge hopper. After the flotation machine is turned on, it will run for a long time. At this time, the sludge hopper is in a long working process, which makes it difficult to clean the outer surface of the sludge hopper. If it cannot be cleaned for a long time, the stains will scab, which will increase the difficulty of cleaning the sludge hopper. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a textile printing and dyeing wastewater treatment device to solve the technical problem that a lot of stains will stick to the outer wall of the sludge hopper.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a textile printing and dyeing wastewater treatment device, including a shallow high-efficiency air flotation tank, wherein a cleaning device is provided on one side of the rotating frame of the shallow high-efficiency air flotation tank, and the cleaning device includes an installation block, wherein the installation block is connected to a scraper through a connecting mechanism;

[0006] The connecting mechanism includes a first connecting mechanism, which includes a first rotating rod. A spring sleeve rod is rotatably connected to one side of the first rotating rod. One end of both the first rotating rod and the spring sleeve rod is rotatably connected to the mounting block. A scraper is rotatably connected to the other end of the first rotating rod.

[0007] The mounting block has a groove, and a lever is rotatably connected to one side of the groove. One end of the lever is rotatably connected to the scraper.

[0008] By adopting the above technical solutions, the high-efficiency air flotation tank enables suspended solids, grease and other pollutants in textile printing and dyeing wastewater to effectively float to the surface, facilitating subsequent treatment and achieving efficient separation of pollutants.

[0009] Furthermore, the bottom of the scraper is connected to the mounting block via a support mechanism, the support mechanism including a base.

[0010] By adopting the above technical solution, the bottom of the scraper is connected to the mounting block through a support mechanism, which ensures the stability and reliability of the scraper during the cleaning process. The support mechanism provides reliable support performance for the scraper.

[0011] Furthermore, the base is rotatably connected to a support rod via a torsion shaft, and a sliding block is rotatably connected to the top of the support rod.

[0012] By adopting the above technical solution, the base is rotatably connected to the support rod via a torsion shaft, which allows the support rod to flexibly adjust its angle to adapt to cleaning needs and to adapt to the overall movement.

[0013] Furthermore, a guide strip is slidably connected to the sliding block, and the guide strip is fixedly connected to the scraper.

[0014] By adopting the above technical solution, the guide strip slidably connected on the sliding block provides a stable movement trajectory for the scraper, ensuring the uniformity and effectiveness of cleaning.

[0015] Furthermore, multiple sets of the support mechanism and the connecting mechanism are provided, and the multiple sets of the support mechanism and the connecting mechanism are arranged in an alternating manner.

[0016] By adopting the above technical solution, the staggered arrangement of multiple sets of support and connection mechanisms enhances the overall stability and load-bearing capacity of the cleaning device.

[0017] Furthermore, a flow channel is provided on the top of the scraper, and a flow plate is fixedly connected to one side of the scraper. The flow channel and the flow plate are used to guide the flow of sludge.

[0018] By adopting the above technical solution, the diversion groove set on the top of the scraper can guide the flow of sludge, avoiding the accumulation and adhesion of sludge on the scraper.

[0019] Furthermore, a float is fixedly connected to one end of the lever, and the float is used to provide buoyancy.

[0020] By adopting the above technical solution, the float fixedly connected to one end of the lever provides buoyancy support for the scraper, reducing the overall weight and burden of the cleaning device.

[0021] Furthermore, the connecting mechanism includes a second connecting mechanism, which includes a second rotating rod. One end of the second rotating rod is rotatably connected to the mounting block, and the other end of the second rotating rod is rotatably connected to the scraper.

[0022] By adopting the above technical solution, the second connecting mechanism included in the connecting mechanism provides another way to connect the scraper, increasing the diversity and adaptability of the cleaning device and enabling a reduction in the overall number of components.

[0023] In summary, the present invention has the following main advantages:

[0024] 1. This utility model, by setting up a cleaning device, mounting block, and connecting mechanism, can automatically clean the outer wall of the sludge bucket in a shallow high-efficiency flotation tank. It can significantly improve the automation level of textile printing and dyeing wastewater treatment equipment, maintain cleanliness even during long-term operation, and eliminate the need for manual intervention. This greatly reduces the labor intensity of workers, improves work efficiency, ensures the timeliness and effectiveness of cleaning, and avoids equipment failure or reduced treatment efficiency caused by untimely or incomplete manual cleaning. This improves wastewater treatment efficiency and quality. Through the synergistic effect of the connecting mechanism and support mechanism, the stability and flexibility of the scraper during the cleaning process are ensured, extending the service life of the equipment. The cleaning device helps extend the service life of the entire wastewater treatment equipment. By regularly cleaning the outer wall of the sludge bucket, the long-term accumulation of sludge and impurities can be avoided, preventing corrosion and damage to the equipment, thus protecting the structure and performance of the equipment. This also prevents the adhesion and accumulation of stains. The efficient operation of the cleaning device also reduces downtime caused by equipment failure, improving the utilization rate and reliability of the equipment.

[0025] 2. This utility model, through the setting of a lever, a connected float, and a second connecting mechanism, allows the float to utilize its buoyancy characteristics to provide an upward support force for the scraper in the cleaning device. This support force helps the scraper to quickly reset after cleaning. Simultaneously, in conjunction with the second connecting mechanism, it reduces the use of spring sleeves, thereby reducing energy consumption and mechanical wear during the operation of the cleaning device and extending its service life. The buoyancy of the float remains constant, ensuring that the scraper maintains appropriate contact pressure with the outer wall of the sludge hopper. This prevents damage to the sludge hopper due to excessive pressure or incomplete cleaning due to insufficient pressure, enabling the cleaning device to more flexibly handle various complex working conditions and improving the efficiency and quality of wastewater treatment.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0034] The embodiments of this utility model will be described below based on its overall structure.

[0035] Example 1:

[0036] A wastewater treatment device for textile printing and dyeing, such as Figures 1-6 As shown, it includes a shallow high-efficiency air flotation tank 1. A cleaning device 3 is provided on one side of the rotating frame 2 of the shallow high-efficiency air flotation tank 1. The cleaning device 3 includes a mounting block 31. The mounting block 31 is connected to a scraper 33 through a connecting mechanism 5.

[0037] The connecting mechanism 5 includes a first connecting mechanism 51, which includes a first rotating rod 321. A spring sleeve rod 322 is rotatably connected to one side of the first rotating rod 321. One end of both the first rotating rod 321 and the spring sleeve rod 322 is rotatably connected to the mounting block 31. A scraper 33 is rotatably connected to the other end of the first rotating rod 321.

[0038] The mounting block 31 has a groove 35, and a lever 36 is rotatably connected to one side of the groove 35. One end of the lever 36 is rotatably connected to the scraper 33. The cleaning device 3 set on one side of the rotating frame 2 can automatically clean the outer wall of the sludge bucket through the scraper 33 connected by the connecting mechanism 5, avoiding the adhesion of stains and improving the processing efficiency and maintainability of the equipment.

[0039] See Figure 3 , Figure 4 , Figure 6 The bottom of the scraper 33 is connected to the mounting block 31 through the support mechanism 34. The support mechanism 34 includes a base 341, which provides a solid foundation for the entire support structure and enhances the support strength of the scraper.

[0040] See Figure 3 , Figure 4 , Figure 6 The base 341 is rotatably connected to the support rod 342 via a torsion shaft. The top of the support rod 342 is rotatably connected to the sliding block 343. The rotatable connection between the top of the support rod 342 and the sliding block 343 further increases the flexibility and adaptability of the scraper 33 in the cleaning process, enabling the scraper 33 to reliably achieve the cleaning effect.

[0041] See Figure 3 , Figure 4 , Figure 6 A guide strip 344 is slidably connected to the sliding block 343. The guide strip 344 is fixedly connected to the scraper 33. The fixed connection between the guide strip 344 and the scraper 33 ensures that the scraper can always maintain the correct position and direction during the cleaning process.

[0042] See Figure 1 , Figure 2 , Figure 3 , Figure 5The support mechanism 34 and the connecting mechanism 5 are provided in multiple sets, and the multiple sets of support mechanism 34 and connecting mechanism 5 are arranged in an alternating manner. This alternating arrangement also enables the scraper to move more reliably during the cleaning process to cover the outer wall of the sludge bucket and improve the cleaning efficiency.

[0043] See Figure 1 , Figure 3 The top of the scraper 33 is provided with a flow channel 37, and a flow plate 38 is fixedly connected to one side of the scraper 33. The flow channel 37 and the flow plate 38 are used to guide the flow of sludge. The flow plate 38 fixedly connected to one side of the scraper further enhances the guiding effect of sludge and ensures that the sludge can be smoothly discharged into the sludge recycling tank.

[0044] The implementation principle of this utility model is as follows: First, textile printing and dyeing wastewater enters a shallow high-efficiency air flotation tank 1. In the air flotation tank, by adding an appropriate amount of flotation agent and generating microbubbles, suspended solids, grease, and other pollutants in the wastewater adhere to the bubbles and float to the water surface, thereby achieving preliminary separation of pollutants. At the same time, the sludge hopper on the shallow high-efficiency air flotation tank 1 recovers the suspended solids, grease, and other pollutants that have floated to the water surface and formed scum.

[0045] When the sludge hopper is pressed against the lever 36, the cleaning device 3 starts to work. The lever 36 drives the scraper 33 to move to one side, so that the scraper 33 can slide to one side along the guide bar 344, so that the outer surface of the sludge hopper can be scraped.

[0046] When the lever 36 moves to its limit position, it disengages from the sludge bucket. At this time, the spring sleeve 322 retracts, pulling the first rotating rod 321 to reset, which in turn drives the scraper 33 to return to its initial position along the guide bar 344. The lever 36 then resets, waiting for the next scraping.

[0047] Example 2:

[0048] See Figure 4 One end of the lever 36 is fixedly connected to a float 4, which provides buoyancy. The buoyancy of the float also makes it easier for the scraper to move and reset during the cleaning process, improving the convenience and efficiency of cleaning.

[0049] See Figure 4 The connecting mechanism 5 includes a second connecting mechanism 52, which includes a second rotating rod 521. One end of the second rotating rod 521 is rotatably connected to the mounting block 31, and the other end of the second rotating rod 521 is rotatably connected to the scraper 33. The rotatable connection between one end of the second rotating rod 521 and the mounting block 31, and the rotatable connection between the other end of the second rotating rod 521 and the scraper 33, allows the scraper to adjust its angle and position more flexibly during the cleaning process, thereby improving the accuracy and effectiveness of the cleaning.

[0050] The implementation principle of this utility model is as follows: First, as a replacement for the first connecting mechanism 5 in the embodiment, the float 4 fixedly connected to one end of the lever 36 provides a certain buoyancy to the scraper 33, so that there is no need to use the spring sleeve 322 as the reset power. One end of the second rotating rod 521 in the second connecting mechanism 52 is rotatably connected to the mounting block 31, and the other end is rotatably connected to the scraper 33, providing a stable support structure for the scraper, so that the scraper 33 can reliably scrape.

[0051] All parts not covered in this utility model are the same as or can be implemented using existing technologies, and will not be described in detail here.
