Description

Technical Field

[0001] This utility model relates to the technical field of wastewater treatment devices, specifically an adsorption-type heavy metal wastewater treatment device. Background Technology

[0002] Heavy metal wastewater refers to wastewater containing high concentrations of heavy metal ions, such as lead, mercury, cadmium, and chromium. These heavy metal ions pose serious threats to the environment and human health. Therefore, the treatment of heavy metal wastewater has become one of the important tasks in the field of environmental protection. The principle of heavy metal wastewater treatment is generally to remove heavy metal ions from the wastewater or convert them into non-toxic substances. Common treatment methods include chemical precipitation, adsorption, ion exchange, membrane separation, etc. The appropriate treatment method can be selected according to the actual situation. Regarding current adsorption-based wastewater treatment methods, adsorption treatment involves setting up adsorption materials such as activated carbon, natural zeolite, and biochar. This method allows heavy metal wastewater to pass directly through the adsorption material. However, in actual use, wastewater enters the treatment tank directly through the inlet pipe, which is often located in the middle or at the edge of the tank. This causes the wastewater to easily concentrate in the middle or at the edge of the adsorption element. If the filtration is concentrated in one place for a long time, the filtration effect at that location on the adsorption element can be reduced or even eliminated, resulting in a decrease in the subsequent wastewater treatment effect. Utility Model Content

[0015] 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.

[0016] Example: Figure 1-4 As shown, this utility model provides an adsorption-type heavy metal wastewater treatment device, including a treatment tank 1. An inlet pipe 11 is installed on the top of the treatment tank 1, and a flange is provided on the top of the inlet pipe 11. A movable hopper 2 is provided inside the treatment tank 1. An installation frame 12 is fixedly installed below the movable hopper 2 inside the treatment tank 1. A screening filter screen 13 is fixedly installed inside the installation frame 12. An adsorption element 14 is fixedly installed below the screening filter screen 13 in the treatment tank 1. The adsorption element 14 can be one of the commonly used activated carbon, natural zeolite, and biochar, or a combination of multiple materials. The actual selection is determined based on the metal content in the wastewater being treated. The bottom of the movable bucket 2 is provided with two distribution buckets 21. Three equally spaced through slots 22 are opened in the middle of the movable bucket 2. A rotating plate 23 is fixedly provided on the top of the movable bucket 2. The edge of the rotating plate 23 movably penetrates the treatment tank 1. A toothed ring 24 is fixedly provided on the upper surface of the rotating plate 23 outside the treatment tank 1. A vertically arranged rotating rod 25 is rotatably provided on the outer wall of the treatment tank 1. A drive gear 26 is fixedly provided at the upper end of the rotating rod 25. The drive gear 26 is meshed with the toothed ring 24.

[0017] A vertically arranged drive shaft 28 is rotatably mounted on the outer wall of the treatment tank 1 near the rotating rod 25. A drive gear 29 is fixed on the drive shaft 28. A transmission gear 27 is fixed on the bottom of the rotating rod 25. The drive gear 29 meshes with the transmission gear 27. The rotation of the drive gear 29 causes the transmission gear 27 and the drive gear 26 above it to rotate, providing power for the rotation of the gear ring 24.

[0018] The tooth pitch of the drive gear 29 is one-quarter of that of the transmission gear 27. This arrangement allows the drive gear 29 to rotate intermittently while rotating to drive the drive gear 29 to rotate.

[0019] A support frame 3 is fixedly provided on the outer wall of the treatment tank 1 near the rotating rod 25 and the drive shaft 28. The rotating rod 25 and the drive shaft 28 are both rotatably mounted on the support frame 3. A drive motor 31 is fixedly provided on the support frame 3 near the drive shaft 28. The output end of the drive motor 31 is coaxially fixed on the drive shaft 28.

[0020] A protective cover 4 is fixedly installed on the outer wall of the treatment tank 1 near the rotating plate 23. The rotating plate 23 and the toothed ring 24 are both located inside the protective cover 4. The protective cover 4 protects the rotating plate 23 and the toothed ring 24 to prevent external impurities from interfering with and entering the treatment tank 1.

[0021] A rubber sealing ring 41 is fixedly provided on the upper surface of the rotating plate 23 near the treatment tank 1. The rubber sealing ring 41 is located on the inner wall of the treatment tank 1. The rubber sealing ring 41 can seal the position where the rotating plate 23 penetrates the treatment tank 1 to prevent leakage and improve the performance of the device.

[0022] Working principle: During use, sewage is discharged into the treatment tank 1 through the flange-connected inlet pipe 11. Upon entering the treatment tank 1, the distribution hoppers 21 at the edge of the movable hopper 2 and the evenly spaced channels 22 in the middle of the tank ensure that the sewage is distributed evenly to the edges and center of the treatment tank 1. Therefore, the sewage passing through the movable hopper 2 is not concentrated but evenly distributed throughout the treatment tank 1. Subsequently, the drive motor 31 operates, rotating the drive shaft 28. This causes the drive gear 29 fixed on the drive shaft 28 to rotate the meshing transmission gear 27. The transmission gear 27, in turn, drives the top drive gear 26 via the rotating rod 25, ultimately causing the drive gear 26 to rotate the meshing gear ring 24. This causes the toothed ring 24 to drive the fixed rotating plate 23 and the movable bucket 2 to rotate. In this way, the distribution bucket 21 on the movable bucket 2 will rotate around the edge of the lower adsorption element 14, so that the sewage discharged through the distribution bucket 21 and the through channel 22 can be evenly distributed on the lower screening filter screen 13 and adsorption element 14, avoiding concentrated distribution and ensuring the service life of the adsorption element 14. Subsequently, the sewage will first pass through the screening filter screen 13 to filter out large particles and impurities. Then, the sewage that has passed through the filter screen will come into contact with the adsorption element 14. The adsorption element 14 adsorbs metal ions and other substances in the sewage. The specific adsorption element 14 can be one of the commonly used activated carbon, natural zeolite and biochar, or a combination of multiple materials. The actual selection is determined according to the metal content in the sewage to be treated. Meanwhile, the teeth of the drive gear 29 are one-quarter of those of the transmission gear 27. This arrangement allows the drive gear 29 to rotate intermittently when it is driven to rotate. This, in turn, acts on the drive gear 26 and the gear ring 24, causing the rotating plate 23 to drive the movable bucket 2 to rotate intermittently. This ensures that the wastewater discharged through the distribution bucket 21 and the through trough 22 can intermittently remain directly above the adsorption element 14 each time. This avoids rapid movement, which would prevent each adsorption element 14 from filtering more wastewater, and also avoids prolonged retention that would cause excessive wastewater accumulation and a rapid decrease in filtration efficiency.

[0023] All standard parts used in this invention can be purchased from the market, and irregularly shaped parts can be customized according to the description and drawings. The specific connection methods of each part all adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts, and equipment all adopt conventional models in the prior art, and the circuit connections adopt conventional connection methods in the prior art, which will not be described in detail here. Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope.
