Description

Technical Field

[0001] This invention relates to the technical field of wastewater filtration and treatment, and in particular to a deep purification treatment device for heavy metal wastewater. Background Technology

[0002] With the rapid development of modern industry, industries such as electroplating, metallurgy, mining, chemical industry, and battery manufacturing generate a large amount of industrial wastewater containing heavy metal ions during the production process. This wastewater usually contains a large amount of toxic heavy metals. If it is discharged directly without effective treatment, it will cause serious pollution to water bodies and soil ecosystems, and through the food chain, it will accumulate and ultimately endanger human health. Therefore, efficient and stable deep purification treatment of heavy metal wastewater has become an important issue in the field of environmental protection.

[0003] Currently, activated carbon filter media is commonly used as the main adsorption component in existing heavy metal wastewater treatment equipment. When wastewater containing heavy metals flows through the activated carbon filter media, the heavy metal ions are adsorbed on the surface of the activated carbon, thereby purifying the water. However, this traditional treatment method has revealed significant technical defects in practical applications: the activated carbon filter media gradually becomes saturated during long-term operation, and its filtration capacity decreases accordingly, resulting in unstable effluent quality that cannot meet strict discharge standards or reuse requirements. To restore its filtration performance, operators need to shut down the machine, disassemble the filter equipment shell, remove the saturated activated carbon filter media, and perform physical cleaning (such as backwashing) or chemical regeneration. After cleaning, it is reinstalled. This process is not only cumbersome and time-consuming, requiring frequent manual intervention, increasing labor intensity and labor costs, but also causes the entire wastewater treatment process to be interrupted due to long-term shutdown for maintenance, reducing the system's continuous operation capability and overall treatment efficiency, which is particularly unfavorable for industrial scenarios that require continuous treatment. Summary of the Invention

[0004] In view of this, the present invention provides a deep purification treatment device for heavy metal wastewater, which can solve the problem that existing heavy metal wastewater treatment equipment requires manual periodic removal of activated carbon filter media for physical cleaning or chemical regeneration, which is not only troublesome, time-consuming and labor-intensive, but also reduces the continuous operation capability and overall treatment efficiency of the system due to long-term downtime maintenance.

The rotating mechanism drives the connecting pipes to change position. Activated carbon filter media is installed inside the connecting pipes. A translation mechanism is mounted on the support platform, and a sliding frame is slidably connected to the translation mechanism. Storage tanks are installed at intervals on the sliding frame. The frame is equipped with an injection mechanism for injecting liquid from the storage tank into the connecting pipe, which cleans the activated carbon filter material. The translation mechanism is also equipped with a sealing plate to seal the end of the connecting pipe. The translation mechanism drives the connecting pipe, the sliding frame, and the sealing plate to move. The sealing plate is equipped with an extraction mechanism for extracting liquid from the connecting pipe. The sliding frame is equipped with a backwashing mechanism for backwashing the activated carbon filter material. The mounting frame is equipped with a feeding mechanism for feeding wastewater, and the feeding mechanism is equipped with a filter plate for filtering wastewater.

[0006] Furthermore, the rotating mechanism includes a mounting frame, a motor, and a rotating frame. The mounting frame is mounted on the support platform, the motor is mounted on the mounting frame, and the rotating frame is slidably connected to the output shaft of the motor. The connecting pipes are arranged in a ring at intervals on the rotating frame.

[0007] Furthermore, the translation mechanism includes an electric slide rail, a support frame, a ring plate, a first electric push rod, and a second electric push rod. The electric slide rail is mounted on the support platform, and the support frame is connected to the slider of the electric slide rail.

The first electric push rod and the second electric push rod are mounted on the support frame. The telescopic rod of the first electric push rod is connected to the sliding frame, and the telescopic rod of the second electric push rod is connected to the closing plate.

[0008] Furthermore, the injection mechanism includes a first water pump, a first connector, and an input pipe. The first water pump is installed at intervals on the sliding frame. The outlet of the first water pump is connected to the first connector, which is used to connect with the end of the connector pipe. The inlet of the first water pump is connected to the storage tank via an input pipe.

[0009] Furthermore, the extraction mechanism includes a second water pump and an output pipe. The second water pump is installed on the sealing plate, and the output pipe is connected between the inlet of the second water pump and the sealing plate.

[0010] Furthermore, the backwashing mechanism includes a third water pump, a connecting plate, a second connector, a water supply pipe, and a drain pipe. The third water pump and the connecting plate are mounted on the sliding frame. The second connector is provided on the connecting plate. A water supply pipe is connected between the second connector and the outlet of the third water pump. A drain pipe is provided on the mounting frame.

[0013] The beneficial effects of the present invention are as follows: 1. By setting up a rotating mechanism and a translation mechanism, the present invention realizes the automatic switching of multiple activated carbon filter media units (connecting pipes). While cleaning or regenerating one activated carbon filter media, other activated carbon filter media can continue to carry out wastewater purification operations, avoiding the interruption of treatment caused by the shutdown for cleaning of traditional equipment. This realizes continuous, stable and efficient treatment of heavy metal wastewater, and greatly improves the overall operating efficiency and treatment capacity of the system.

[0014] 2. This invention integrates an injection mechanism, an extraction mechanism, and a backwashing mechanism, which can automatically inject chemical reagents from the storage tank into the connecting pipe to chemically regenerate the activated carbon filter material. After the treatment is completed, the waste liquid is automatically extracted, followed by backwashing with clean water. The entire cleaning and regeneration process does not require manual disassembly of the filter element, realizing online and automated maintenance of the activated carbon filter material, effectively reducing the labor intensity of operators, and lowering labor costs and maintenance time.

[0015] 3. By setting up a feeding mechanism and a collection mechanism with rotating filter plates, this invention can effectively remove large particulate impurities and suspended solids from wastewater before it enters the activated carbon treatment unit, preventing them from clogging the activated carbon filter material or pipes. At the same time, by using a turbine drive and a chute guide structure, the automatic rotation of the filter plates and the automatic discharge of filter residue are realized, further improving the stability and self-cleaning ability of the system.

[0035] See Figure 8 As shown, the backwashing mechanism includes a third water pump 1501, a connecting plate 1502, a second connector 1503, a water supply pipe 1504, and a drain pipe 1505; the third water pump 1501 is installed in the middle of the right side of the sliding frame 10; the connecting plate 1502 is connected to the lower front side of the sliding frame 10; the second connector 1503 is provided on the lower left side of the connecting plate 1502; the water supply pipe 1504 is connected between the second connector 1503 and the outlet of the third water pump 1501; the drain pipe 1505 is provided on the upper right front side of the mounting frame 601, and the drain pipe 1505 is aligned with the second connector 1503.

[0036] See Figures 9-11As shown, it also includes a feeding mechanism, which includes a connecting frame 16, a feed pipe 17, a cross-shaped partition frame 18, a connecting rod 19, and a turbine 20; the connecting frame 16 is installed on the upper left side of the mounting frame 2, and a discharge port 1601 is opened on the lower right side of the connecting frame 16, which is connected to the pipe 3. A notch is opened on the upper right side of the connecting frame 16, and the connecting frame 16 is inclined from left to right so that the wastewater in the connecting frame 16 can be discharged from the discharge port 1601; the feed pipe 17 is connected to the top of the connecting frame 16; the cross-shaped partition frame 18 is rotatably installed inside the connecting frame 16. The cross-shaped partition frame 18 divides the interior of the connecting frame 16 into four chambers. Two of these chambers are connected to the feed pipe 17 and the discharge port 1601, respectively. Four filter plates 21 are slidably arranged on the cross-shaped partition frame 18 at intervals, and the four filter plates 21 are located in the four chambers respectively. The filter plates 21 are inclined with the left side higher than the right side so that the filtered material can slide down from the filter plates 21 to the right. A connecting rod 19 is rotatably arranged on the lower side of the feed pipe 17. The lower end of the connecting rod 19 is connected to the middle of the top of the cross-shaped partition frame 18. Two turbines 20 are arranged on the upper end of the connecting rod 19. The turbines 20 are located inside the feed pipe 17.

[0037] See Figures 9-12 As shown, it also includes a collection mechanism, which includes a guide rod 22 and a collection frame 24; the guide rod 22 is connected to the side of the filter plate 21, and a groove 23 is provided on the inner wall of the connecting frame 16. An inverted V-shaped structure is provided on the groove 23, which is located directly below the notch. The guide rod 22 slides in the groove 23; a collection frame 24 for collecting the filtered material is slidably provided on the upper right side of the mounting frame 2. By sliding the collection frame 24 from the upper side of the mounting frame 2 to the right and then lifting it out, the operator can easily clean the filtered material in the collection frame 24.

[0038] In the initial state, the right end of connecting pipe 4 is connected to the left end of one of the connecting pipes 7 (e.g., Figure 3 As shown), the right ends of the other three connecting pipes 7 are respectively connected to the three first connecting joints 1202, and the left ends of the three connecting pipes 7 are sealed by the sealing plate 13 (as shown). Figure 6 As shown), the right end of the remaining connecting pipe 7 is connected to the second connecting pipe 1503, and the left end is connected to the right end of the drain pipe 1505 (as shown). Figure 8 (as shown) In use, three different chemical reagents are added to three storage tanks 11 respectively. Then, the inlet of the third water pump 1501 is connected to the pipe conveying the cleaning solution. Next, wastewater containing heavy metals is poured into the feed pipe 17, allowing it to enter the corresponding chamber within the connecting frame 16. The wastewater then passes through the filter plate 21, filtering out larger impurities at the top of the filter plate 21. During this process, when the wastewater containing heavy metals comes into contact with the turbine 20 inside the feed pipe 17, the wastewater will… The turbine 20 is driven to rotate, which in turn drives the connecting rod 19, the cross-shaped partition frame 18, and the filter plate 21 to rotate. This causes the cross-shaped partition frame 18 to rotate the positions of the four chambers within the connecting frame 16, allowing the wastewater containing heavy metals discharged from the feed pipe 17 to enter the four chambers. When the chamber containing the filtered wastewater is connected to the discharge port 1601, the filtered wastewater in the chamber will be discharged into the pipe 3 through the discharge port 1601. This achieves automatic filtration of the wastewater containing heavy metals before it is introduced into the pipe 3, preventing larger foreign objects from entering the wastewater. If the activated carbon filter material 8 becomes clogged, when the filter plate 21 rotates, it will cause the guide rod 22 to rotate as well, causing the guide rod 22 to slide along the groove 23. When the guide rod 22 rotates into the inverted V-shaped structure area of ​​the groove 23, the guide rod 22 is lifted upward along the inclined surface of the inverted V-shaped structure, causing the guide rod 22 to move the filter plate 21 upward, so that the filtered material on the filter plate 21 can slide to the right through the notch into the collection frame 24 for collection. When the guide rod 22 rotates out of the inverted V-shaped structure area, it is guided downward to reset by the V-shaped structure contour. The filter plate 21 is simultaneously driven back to its initial position, thus automatically cleaning the filtered material on the filter plate 21. When wastewater containing heavy metals is introduced into the pipe 3, the wastewater containing heavy metals will be guided into the connecting pipe 4 through the pipe 3, and then the connecting pipe 4 will guide the wastewater containing heavy metals into the corresponding connecting pipe 7. When the wastewater containing heavy metals flows through the activated carbon filter material 8 in the connecting pipe 7, the heavy metal pollutants are effectively adsorbed and purified. The purified water flows out along the connecting pipe 7 and is finally discharged from the discharge frame on the support platform 1, completing the entire purification process. When chemical regeneration and cleaning of the activated carbon filter material 8 are required, the solenoid valve 5 is closed, preventing wastewater containing heavy metals from flowing into the connecting pipe 4 from the pipe 3. Then, the electric slide rail 901 drives the support frame 902 to move to the right, thereby moving the ring plate 903, the connecting pipe 7, and the rotating frame 603 to the right until the left ends of the corresponding two connecting pipes 7 are disconnected from the connecting pipe 4 and the drain pipe 1505, respectively. Next, the first electric push rod 904 drives the sliding frame 10 to move to the right, thereby moving the liquid storage tank 11, the first water pump 1201, and the first connecting joint 1202 to the right until the three first connecting joints 1202 are disconnected from the right ends of the corresponding three connecting pipes 7, and simultaneously, the second electric push rod 905 drives... The sealing plate 13 moves to the left until it no longer seals the left ends of the corresponding three connecting pipes 7. Then, the rotating frame 603 is driven to rotate 72 degrees (counterclockwise when viewed from the right and left) by the motor 602, thereby causing the connecting pipes 7 and the ring plate 903 to rotate 72 degrees, thus swapping the positions of the five connecting pipes 7. After the five connecting pipes 7 have been swapped, the sealing plate 13 is driven to move to the right to reset by the second electric push rod 905, so that the sealing plate 13 re-seals the left ends of the corresponding three connecting pipes 7. At the same time, the sliding frame 10 is driven to move to the left to reset by the first electric push rod 904, thereby causing the liquid storage tank 11, the first water pump 1201 and the first connecting joint 1202 to move to the left to reset, so that the three first connecting joints 1202 respectively connect to the corresponding three connecting pipes 7. The right end of connector 7 is reconnected, and then the support frame 902 is moved to the left and reset via the electric slide rail 901. This causes the ring plate 903, connector 7, and rotating frame 603 to move to the left and reset, so that the left ends of the two corresponding connectors 7 are reconnected with the connecting pipe 4 and the drain pipe 1505, respectively. Then, the solenoid valve 5 is opened to allow the wastewater containing heavy metals in pipe 3 to continue to flow into the connecting pipe 4. This allows the wastewater containing heavy metals to enter the connector 7 for purification treatment through the connecting pipe 4. In this way, by switching different connectors 7 to connect with the connecting pipe 4, the activated carbon filter media 8 in different connectors 7 can purify the wastewater containing heavy metals. Afterward, the corresponding first water pump 1201 is used to purify the wastewater through the first connector 1202 and the input pipe 12. 03. The chemical reagent in the corresponding storage tank 11 is drawn into the corresponding connector 7, so that the chemical reagent enters the corresponding connector 7 to chemically regenerate the activated carbon filter material 8. After the activated carbon filter material 8 in the connector 7 has completed the chemical regeneration treatment, the second water pump 1401 is used to extract the chemical reagent in the corresponding connector 7 through the output pipe 1402 to clean the chemical reagent in the connector 7. After repeating the above operation, the right end of the connector 7 can be connected to three different first connectors 1202 in sequence, so that different chemical reagents in the three storage tanks 11 can be used to chemically regenerate the activated carbon filter material 8 in sequence (different chemical reagents can adsorb different pollutants on the activated carbon filter material 8).This ensures that the activated carbon filter material 8 restores its surface activity and adsorption capacity. Afterwards, the right end of the connecting pipe 7 is sequentially connected to three different first connectors 1202. The connecting pipe 7 then switches positions to connect with the second connector 1503 and the drain pipe 1505. After the left and right ends of the connecting pipe 7 are connected to the drain pipe 1505 and the second connector 1503 respectively, the third water pump 1501 draws cleaning solution through the water supply pipe 1504 and the second connector 1503 into the corresponding connecting pipe 7. This allows clean water to backwash the activated carbon filter material 8 within the connecting pipe 7 until it is thoroughly cleaned. The cleaning solution from the backwash is then discharged through the drain pipe 1505. In this way, the activated carbon filter material 8 can be automatically chemically regenerated and cleaned.
