Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a high-efficiency wastewater heavy metal ion purification device applied to the dyeing and printing industry. Background Technology

[0002] In the printing and dyeing industry, metal complex dyes are often used to obtain specific colors and effects. These dyes contain heavy metal ions such as antimony, arsenic, lead, chromium, and copper. When the dye is not completely fixed on the fabric or decomposes during use, these heavy metal ions will enter the wastewater. Before discharge, the heavy metal ions in the wastewater need to be purified to avoid polluting the environment.

[0003] According to the published patent CN 216549899 U, a high-efficiency heavy metal ion wastewater treatment device uses multiple sets of gears to drive a stirring shaft, which in turn drives the stirring blades. This allows the treatment liquid in the treatment tank to fully mix and react with the wastewater, achieving a highly efficient treatment effect and effectively solving the problem of lacking a stirring structure. Simultaneously, the wastewater enters a sedimentation tank through an electromagnetic valve, where it undergoes settling. Meanwhile, the treatment tank begins processing the next batch of wastewater, improving the equipment's efficiency. In developing this invention, the inventors discovered that the existing technology suffers from at least the following unresolved problems: although the use of a sedimentation tank solves the problem of lacking a sedimentation treatment tank structure, traditional sedimentation tanks rely on the wastewater to settle autonomously, which is time-consuming and affects the addition of subsequent wastewater. Furthermore, the settled impurities accumulate in the sedimentation tank, making cleaning difficult and potentially causing blockages over time. Therefore, a new technical solution is needed to address these issues. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a high-efficiency wastewater heavy metal ion purification device for the printing and dyeing industry. This solves the technical problems of the current traditional sedimentation tank, which mainly requires the wastewater to complete the sedimentation on its own, which takes a long time and affects the subsequent addition of wastewater. Moreover, the impurities after sedimentation will accumulate in the sedimentation tank, which is inconvenient to clean and will cause the channel to become blocked over time.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: A high-efficiency wastewater heavy metal ion purification device for the dyeing and printing industry is designed, including a treatment tank, a horizontal plate, a connecting pipe, and a cleaning tank. The inner side of the treatment tank has a pouring tank, a stirring tank, and a sedimentation tank respectively opened from left to right. A support frame is fixedly connected to the outer wall of the treatment tank outside the sedimentation tank. A first electric actuator is fixedly connected to the lower surface of the top of the support frame. A pressure plate is fixedly connected to the bottom of the first electric actuator, and the pressure plate is parallel to the inner bottom of the sedimentation tank. A movable groove is fixedly connected to the side wall of the treatment tank opposite the support frame. A threaded rod is rotatably connected to the inner side of the movable groove. A threaded block is threadedly connected to the surface of the threaded rod, and the threaded block... A connecting block is fixedly connected to the top, and the other end of the connecting block is fixedly connected to the top of the scraper. The scraper is located inside the sedimentation tank and is laterally slidably connected inside the sedimentation tank. A cleaning trough is opened at the bottom of the sedimentation tank near the right edge of the treatment tank, and cleaning ports are opened on both the front and rear sides of the cleaning trough. The cleaning ports are connected to the outside of the treatment tank. A sealing cover is movably connected to one side of the cleaning port of the cleaning trough, and a fixing frame is fixedly connected to the outer wall of the treatment tank outside the cleaning port on the other side of the cleaning trough. A second electric push rod is fixedly connected to the surface of the fixing frame facing the cleaning port. A cleaning push plate is fixedly connected to the other end of the second electric push rod. The cleaning push plate is located inside the cleaning port and fits against the inner wall of the cleaning port.

[0006] Preferably, a water inlet groove is provided through the pressure plate surface on both sides of the first electric push rod, and an intercepting filter screen is fixedly connected to the bottom opening of the water inlet groove, and the bottom surface of the filter screen and the bottom surface of the pressure plate are on the same horizontal plane.

[0007] Preferably, the pouring tank and the stirring tank are interconnected by a connecting tank, and an adsorption plate is vertically and movably inserted into the inner side of the connecting tank.

[0008] Preferably, the two ends of the horizontal plate are fixedly connected to the front and rear inner sidewalls of the mixing tank, a servo motor is fixedly connected to the center of the top of the horizontal plate, and a stirring rod is rotatably connected to the center of the bottom of the horizontal plate, with the outer end of the drive shaft of the servo motor fixedly connected to the top of the stirring rod.

[0009] Preferably, both ends of the connecting pipe penetrate the outer wall of the treatment tank and are connected to the stirring tank and the sedimentation tank, respectively.

[0010] Preferably, a drain outlet is provided at the bottom of the inner wall of the sedimentation tank, and a screen is fixedly connected to the inner opening of the drain outlet.

[0011] Preferably, a second servo motor is fixedly connected to the outer surface of one end of the moving slot, and the outer end of the drive shaft of the second servo motor is fixedly connected to one end of the threaded rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model promotes sedimentation by using a first electric actuator and a pressure plate. During the sedimentation process of wastewater, the first electric actuator extends and drives the pressure plate to descend slowly. During the descent, the sediment is squeezed together and pushed to the bottom of the sedimentation tank, thereby accelerating the sedimentation process, eliminating the need for long waiting times, and improving the wastewater treatment efficiency.

[0014] 2. This utility model, through a moving groove, threaded rod, threaded block, scraper, cleaning groove, and No. 2 electric push rod, can quickly clean up sediment. After the No. 2 servo motor is started, it drives the threaded rod to rotate, causing the threaded block to move laterally along with the scraper. During the movement, the scraper scrapes the sediment, causing it to move along with the sediment and eventually enter the cleaning groove. At this time, the No. 2 electric push rod is activated, driving the cleaning push plate to move in the cleaning groove, thereby pushing the sediment out from the cleaning port on the other side, avoiding the accumulation of sediment, and making the cleaning process convenient and fast, thus improving the cleaning efficiency.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0020] Example 1: A high-efficiency wastewater heavy metal ion purification device for the printing and dyeing industry, see [link to example]. Figures 1 to 3The system includes a treatment tank 1, a horizontal plate 10, a connecting pipe 901, and a cleaning tank 14. From left to right, the inner side of the treatment tank 1 is provided with a pouring tank 6, a stirring tank 9, and a sedimentation tank 13. A support frame 2 is fixedly connected to the outer wall of the treatment tank 1 outside the sedimentation tank 13. A first electric push rod 3 is fixedly connected to the lower surface of the top of the support frame 2. A pressure plate 4 is fixedly connected to the bottom of the first electric push rod 3, and the pressure plate 4 is parallel to the inner bottom of the sedimentation tank 13. The first electric push rod 3 drives the pressure plate 4 to slowly descend, thereby squeezing the sediments together during the descent and pressing them to the bottom of the sedimentation tank 13, thus accelerating the sedimentation process and saving time by eliminating the need for long waiting times.

[0021] Meanwhile, a movable groove 16 is fixedly connected to the side wall of the treatment tank 1 opposite the support frame 2. A threaded rod 17 is rotatably connected to the inner side of the movable groove 16. A threaded block 18 is threadedly connected to the surface of the threaded rod 17, and a connecting block 19 is fixedly connected to the top of the threaded block 18. The other end of the connecting block 19 is fixedly connected to the top of the scraper 20. The scraper 20 is located inside the sedimentation tank 13 and is laterally slidably connected inside the sedimentation tank 13. The bottom and left and right side walls of the scraper 20 are in contact with the inner wall of the sedimentation tank 13. Therefore, during the movement, the sediment can be scraped up and moved along with it, ensuring that the sediment is not missed and that all the sediment can be moved at once. In addition, the scraper 20 will also scrape and clean the screen 151 during the scraping process. A cleaning groove 14 is opened at the inner bottom of the sedimentation tank 13 near the right edge of the treatment tank 1, and cleaning ports 21 are opened on both the front and rear sides of the cleaning groove 14. The cleaning port 21 is connected to the outside of the treatment tank 1. A sealing cover 25 is movably connected to the cleaning port 21 on one side of the cleaning tank 14. The sealing cover 25 can ensure that no water leakage occurs. It is opened when the wastewater is discharged and the sediment needs to be cleaned. A fixing frame 22 is fixedly connected to the outer wall of the treatment tank 1 outside the cleaning port 21 on the other side of the cleaning tank 14. A second electric push rod 23 is fixedly connected to the surface of the fixing frame 22 facing the cleaning port 21. A cleaning push plate 24 is fixedly connected to the other end of the second electric push rod 23. The cleaning push plate 24 is located inside the cleaning port 21 and fits against the inner wall of the cleaning port 21. The outer wall of the cleaning push plate 24 is provided with a sealing ring to ensure that no water leakage occurs when not in use. When the second electric push rod 23 is activated, it drives the cleaning push plate 24 to move in the cleaning tank 14, thereby pushing the sediment out from the cleaning port 21 on the other side, avoiding sediment accumulation. The cleaning process is convenient and fast, improving the cleaning efficiency.

[0022] For details, see Figure 1Water inlet channels 5 are provided through the pressure plates 4 on both sides of the first electric push rod 3. A filter screen 501 is fixedly connected to the bottom opening of the water inlet channel 5, and the bottom surface of the filter screen is at the same level as the bottom surface of the pressure plate 4. The water inlet channel 5 facilitates the passage of wastewater when squeezing the sediment, avoiding the wastewater having nowhere to move and thus being unable to be squeezed down. In addition, the filter screen 501 can intercept the sediment, preventing it from passing through the water inlet channel 5 with the wastewater, thus rendering the squeezing meaningless.

[0023] Further, see Figure 2 The pouring tank 6 and the stirring tank 9 are connected to each other through the connecting tank 8, and an adsorption plate 7 is vertically and movably inserted into the inner side of the connecting tank 8. The adsorption plate 7 is made of activated carbon, which adsorbs some of the heavy metal ions in the wastewater when the wastewater passes through, reducing the subsequent purification pressure. The adsorption plate 7 can be pulled out and replaced after a period of use, thereby ensuring normal adsorption capacity.

[0024] It is worth noting that, see Figure 1 and Figure 2 The two ends of the horizontal plate 10 are fixedly connected to the front and rear inner sidewalls of the mixing tank 9, respectively. A servo motor 11 is fixedly connected to the center of the top of the horizontal plate 10, and a stirring rod 12 is rotatably connected to the center of the bottom of the horizontal plate 10. The outer end of the drive shaft of the servo motor 11 is fixedly connected to the top of the stirring rod 12. The stirring rod 12 rotates under the drive of the servo motor 11. During the rotation, the wastewater and chemical precipitant are fully mixed, accelerating the reaction and precipitation.

[0025] It is worth noting that, see Figure 1 and Figure 2 Both ends of the connecting pipe 901 penetrate the outer wall of the treatment tank 1 and are connected to the stirring tank 9 and the sedimentation tank 13 respectively. The surface of the connecting pipe 901 is equipped with a valve. During the stirring process in the stirring tank 9, the valve can be temporarily closed and opened to allow wastewater to pass through after sufficient stirring.

[0026] It is worth noting that, see Figure 2 The bottom of the inner wall of the sedimentation tank 13 is provided with a drain outlet 15. A screen 151 is fixedly connected to the inner opening of the drain outlet 15. A valve is provided at the outer opening of the drain outlet 15. The valve is temporarily closed during the sedimentation process and opened after the sedimentation is completed to drain the wastewater. The screen 151 can block the sediment and prevent the sediment from leaving with the wastewater.

[0027] It is worth noting that, see Figure 1 A second servo motor 171 is fixedly connected to the outer surface of one end of the moving groove 16. The outer end of the drive shaft of the second servo motor 171 is fixedly connected to one end of the threaded rod 17. The second servo motor 171 controls the rotation of the threaded rod 17, thereby enabling the threaded block 18 and the scraper 20 to move laterally.

[0028] Working Principle: Wastewater is poured into treatment tank 1 through pouring tank 6. Before reaching mixing tank 9, it undergoes initial adsorption treatment of heavy metal ions by adsorption plate 7. After reaching mixing tank 9, a chemical precipitant such as calcium hydroxide is added. With the start of servo motor 11 and the rotation of stirring rod 12, the heavy metal ions in the wastewater react with the chemical precipitant. Then, the valve on connecting pipe 901 is opened, and the wastewater is introduced into sedimentation tank 13. The suspended solids in the wastewater settle down. Sedimentation is promoted by electric push rod 3 and pressure plate 4. During the sedimentation process, electric push rod 3 extends, causing pressure plate 4 to slowly descend. During the descent, the precipitates are squeezed to the bottom of sedimentation tank 13, thus accelerating the sedimentation process and improving the wastewater treatment efficiency. During the downward pressure, the wastewater flows out of water inlet tank 5 through intercepting filter screen 501. 01 can intercept the sediment. After squeezing, the first electric push rod 3 lifts the pressure plate 4 and opens the valve of the drain outlet 15, allowing the wastewater to pass through the screen 151 and leave. At this time, sediment will remain in the sedimentation tank 13. The sediment can be quickly cleaned by moving the trough 16, the threaded rod 17, the threaded block 18, the scraper 20, the cleaning trough 14, and the second electric push rod 23. After the second servo motor 171 starts, it drives the threaded rod 17 to rotate, causing the threaded block 18 to move laterally with the scraper 20. During the movement, the scraper 20 scrapes the sediment, causing it to move along with the sediment and eventually enter the cleaning trough 14. At this time, the second electric push rod 23 starts, driving the cleaning push plate 24 to move in the cleaning trough 14, thereby pushing the sediment out from the cleaning port 21 on the other side. The cleaning process is convenient and fast, improving the cleaning efficiency. After cleaning, the scraper 20 returns to its original position under the drive of the threaded block 18, and then the next batch of wastewater is treated.
