[0001] This utility model relates to the field of wastewater treatment, and in particular to a heavy metal ion removal device for industrial wastewater treatment. Background Technology

[0002] Industrial wastewater treatment mainly involves removing pollutants from wastewater through physical, chemical, and biological methods to meet discharge standards or enable reuse. There are various methods for removing heavy metal ions from industrial wastewater, including chemical precipitation, bioflocculation, and flotation.

[0003] Heavy metal ion removal devices for industrial wastewater treatment typically include main structures such as reaction tanks, sedimentation tanks, and filters. In the reaction tank, chemical reagents are added to react with heavy metal ions to form precipitates. The sedimentation tank is used to separate heavy metal compounds. The filter further removes residual small particles and constructs a multi-layer adsorption bed structure, with each layer filled with different adsorption materials, such as activated carbon, zeolite, and metal-organic frameworks (MOFs), to achieve efficient adsorption of various heavy metal ions.

[0004] In existing technologies, multilayer adsorption beds are usually a whole with a pre-arranged treatment sequence, making it impossible to treat individual layers and replace ineffective or saturated adsorbents in a timely manner. This affects the efficiency and effectiveness of wastewater treatment, makes it difficult to flexibly adjust the adsorption materials for different pollution levels and types, reduces structural adaptability, increases overall replacement costs and time, and causes resource waste. To address these issues, a heavy metal ion removal device for industrial wastewater treatment is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a heavy metal ion removal device for industrial wastewater treatment, aiming to improve the problem that the existing multi-layer adsorption bed cannot treat a single layer, thus affecting the wastewater treatment efficiency, increasing costs, and causing resource waste.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A heavy metal ion removal device for industrial wastewater treatment includes a reaction tank. A centrifugal shaft is rotatably connected to the inner wall of the reaction tank. Three placement slots are formed on the inner wall of the centrifugal shaft. A filter layer is slidably connected to the inner wall of the placement slots. Multiple filter holes are formed inside the filter layer. A replacement cover is slidably connected to the top of the filter layer. Six bolts are threaded to the outside of the centrifugal shaft. Two of the bolts are threaded to the outside of the replacement cover. An auxiliary component for conveying and discharging wastewater is fixedly connected to the outside of the centrifugal shaft.

[0014] As a further description of the above technical solution:

[0015] A second motor is mounted on the outside of the limiting bar. The drive end of the second motor is fixedly connected to the outside of the rotating shaft. Two traction ropes are fixedly connected to the outside of the rotating shaft.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1 to 3This utility model provides an embodiment of a heavy metal ion removal device for industrial wastewater treatment, comprising a reaction tank 1, a structure for holding the treated wastewater, and a container for storing the treated water. A centrifugal shaft 3 is rotatably connected to the inner wall of the reaction tank 1, fixing its rotational position. Three placement slots 19 are provided on the inner wall of the centrifugal shaft 3 for changing the position of the filter structure. A filter layer 5 is slidably connected to the inner wall of each placement slot 19, allowing the filter layer 5 to be easily opened and its internal material replaced after being released from the locking structure.

[0033] The filter layer 5 has multiple filter holes 7 inside to filter out some water. A replacement cover 6 is slidably connected to the top of the filter layer 5 to protect the internal materials from easy leakage. The centrifugal shaft 3 is externally threaded with six bolts 8 (as shown in the attached diagram). Figure 3 The two bolts 8 have external threads connected to the outside of the replacement cover 6. The bolts 8 are used to lock the replacement cover 6 to the position of the centrifugal shaft 3.

[0034] An auxiliary assembly for conveying and discharging wastewater is fixedly connected to the outside of the centrifuge shaft 3. This auxiliary assembly includes a water supply pipe 4, which is installed externally on the centrifuge shaft 3 to precisely deliver the wastewater to be treated into the centrifuge shaft 3. Multiple water inlets 20 are provided on the outside of the centrifuge shaft 3 to discharge filtered water. A motor 2 is installed externally on the reaction tank 1. The drive end of the motor 2 is fixedly connected to the outside of the centrifuge shaft 3. Starting the motor 2 causes the centrifuge shaft 3 to rotate, thus causing the centrifuge shaft 3 to move most impurities away from the center, facilitating subsequent treatment.

[0035] Reference Figure 1 , Figure 2 and Figure 4 Two limiting strips 9 are fixedly connected to the top of the reaction tank 1. A rotating shaft 11 is rotatably connected inside the two limiting strips 9 to fix the position of the rotating shaft 11. A second motor 10 is mounted outside the limiting strips 9. The drive end of the second motor 10 is fixedly connected to the outside of the rotating shaft 11. Starting the second motor 10 causes the rotating shaft 11 to rotate. Two traction ropes 12 (as shown in the attached diagram) are fixedly connected to the outside of the rotating shaft 11. Figure 4 The rotation of the rotating shaft 11 can shorten the two traction ropes 12. The inner wall of the limiting strip 9 is provided with a slide rail 13, and the inner walls of the two slide rails 13 are slidably connected to the slide bar 14, and the slide rail 13 provides a sliding position for the slide bar 14.

[0036] The other ends of the two traction ropes 12 are fixedly connected to the outside of the sliding bar 14. Shortening the traction ropes 12 can cause the sliding bar 14 to change position. A cleaning plate 18 is fixedly connected to the bottom of the sliding bar 14. Changing the position of the sliding bar 14 can cause the cleaning plate 18 to change position. The outside of the cleaning plate 18 is slidably connected to the inner wall of the reaction tank 1, fixing the sliding location of the cleaning plate 18, so that the cleaning plate 18 can clean the inner wall of the reaction tank 1.

[0037] Two sliding boxes 16 are fixedly connected to the outside of the sliding bar 14. Changes in the position of the sliding bar 14 can cause changes in the position of the two sliding boxes 16. Multiple springs 17 are fixedly connected to the inner wall of each sliding box 16. Changes in the position of the sliding box 16 cause deformation of the multiple springs 17. When the external force is removed, the multiple springs 17 will reset, thereby pulling the sliding box 16 back to its original position. A fixed box 15 is fixedly connected to the other end of each spring 17, fixing its position. The fixed box 15 is externally fixedly connected to the inner wall of the slide rail 13, fixing its position.

[0038] Working principle: By tightening bolt 8, the replacement cover 6 can be separated from the filter layer 5, allowing for the replacement of the internal adsorption material. Multiple layers of adsorption material can be replaced individually, allowing for optimization of the specific performance of each layer. Furthermore, the order of the multiple layers of adsorption material can be adjusted according to the position of the placement tank 19, making it more flexible for different wastewater treatments. After placement, motor 2 is started, and the rotation of the drive end of motor 2 drives the centrifugal shaft 3 to rotate. At this time, the wastewater transported by the water supply pipe 4 can rotate the centrifugal shaft 3, making full contact with multiple filter layers 5, resulting in better filtration effect.

[0039] When motor 10 is started, the rotation of the drive end of motor 10 causes the rotating shaft 11 to rotate. The rotation of the rotating shaft 11 winds up the two traction ropes 12, which in turn pull the sliding strip 14 to slide on the inner wall of the slide rail 13. This causes the sliding strip 14 to drive the cleaning plate 18 to clean the inner wall of the reaction tank 1. The position change of the sliding strip 14 causes the sliding box 16 to change position. The position change of the sliding box 16 causes multiple springs 17 to deform. The reset of the multiple springs 17 causes the sliding box 16 to reset, which in turn causes the sliding strip 14 to reset and the cleaning plate 18 to reset, preparing for the next cleaning. Cleaning the sewage tank after sewage treatment removes the deposited sludge and impurities, preventing them from decomposing and producing harmful gases. Cleaning helps maintain the effective volume of the sewage tank, ensuring the normal operation of the sewage treatment structure and avoiding the impact of excessive sludge accumulation on the treatment effect. Regular cleaning also allows for checking the structural integrity of the sewage tank and timely detection and repair of potential problems.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
