Description

Technical Field

[0001] This utility model relates to the field of groundwater metal element adsorption technology, and in particular to a stepped reaction device for adsorbing metal elements in groundwater. Background Technology

[0002] Groundwater is an important source of drinking water and ecological water resources, but it is susceptible to pollution from industrial wastewater, agricultural non-point source pollution, and landfill leachate, which can lead to excessive levels of metals such as iron and manganese. These pollutants are characterized by high toxicity, easy accumulation, and difficulty in degradation. Long-term consumption or contact with polluted groundwater can cause damage to human organs and disrupt the balance of aquatic ecosystems.

[0003] The commonly used solution is multi-stage adsorption and filtration. By aerating the raw groundwater, the low-valence metal ions in the raw water are oxidized to high-valence states. These ions are then adsorbed by manganese sand or precipitated in a manganese sand filter tank. However, long-term use requires regular replacement of materials such as manganese sand, which is not easy to replace or add quickly and consumes more time and preparation. In addition, the fixed tank makes it difficult to assemble and transport. Therefore, a stepped reaction device for adsorbing metal elements in groundwater is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a stepped reaction device for adsorbing metal elements in groundwater, aiming to improve the problems of low material replacement rate of manganese sand and other materials in the prior art, and the difficulty in assembling and transporting the fixed tank.

The buckle assembly is used to fix the sand filter tank 6, the manganese sand tank 7, and the carbon filter tank 8. Filter components are installed in the middle of the sand filter tank 6, the manganese sand tank 7, and the carbon filter tank 8.

[0035] Reference Figure 2 and Figure 5 The snap-fit ​​assembly includes a second fixing ring 15, which is fixedly connected to the outside of the bracket 5. The second fixing ring 15 is rotatably connected to a first fixing ring 14. A sand filter tank 6, a manganese sand tank 7, and a carbon filter tank 8 are installed between the two. A buckle 16 is rotatably connected to the outside of the first fixing ring 14, and a hook 17 is fixedly connected to the outside of the second fixing ring 15. The buckle 16 and the hook 17 are interlocked. Through the connection of the buckle 16 and the hook 17, the first fixing ring 14 and the second fixing ring 15 can be fixed to each other, thereby fixing the sand filter tank 6, the manganese sand tank 7, and the carbon filter tank 8. Similarly, the fixing can be disconnected, which facilitates the installation of the tanks, the disassembly and transportation of the tanks, and improves work efficiency.

[0036] Reference Figure 1 , Figure 3 and Figure 4 The filtration assembly includes an inner tank 19, which is installed in the middle of the sand filter tank 6, manganese sand tank 7, and carbon filter tank 8. The inner tank 19 in the middle of the sand filter tank 6, manganese sand tank 7, and carbon filter tank 8 contains quartz sand, manganese sand, and activated carbon, respectively. The quartz sand filters out large particles from the groundwater, the manganese sand adsorbs and precipitates metal ions, and the activated carbon removes odors. This is existing technology and will not be elaborated further. Each of the sand filter tank 6, manganese sand tank 7, and carbon filter tank 8 has a fixedly connected protrusion 21. The bottom of the inner tank 19 has a groove 20, and the protrusion 21 is slidably connected inside the groove 20 to restrict the movement direction of the inner tank 19. A pumping assembly is installed between the sand filter tank 6, manganese sand tank 7, and carbon filter tank 8. The pumping assembly includes a water pump 3, which is fixedly connected to the bottom. At the top of seat 11, the inlet end of water pump 3 is fixedly connected to the outlet pipe 9, and the outlet end of water pump 3 is fixedly connected to the inlet pipe 12. Sand filter tank 6, manganese sand tank 7, and carbon filter tank 8 are respectively connected to the outlet pipe 9 and the inlet pipe 12. The permeate water from the bottom of the previous tank is pumped into the top of the next tank to achieve cascade purification. The outer side of the middle of sand filter tank 6, manganese sand tank 7, and carbon filter tank 8 are all rotatably connected to sealing doors 10 through rotating shafts 18. Sealing doors 10 are used to seal the tank to prevent liquid from leaking out of the inner tank 19. Sealing doors 10 are connected to sand filter tank 6, manganese sand tank 7, and carbon filter tank 8 through buckles 16 and hooks 17. The connection of buckles 16 and hooks 17 allows the sealing doors 10 to be opened and closed, making it convenient to take out and put in the inner tank 19, so as to facilitate the quick replacement of materials such as manganese sand and reduce the preparation time for replacement.

[0037] Reference Figure 1 and Figure 6 A control box 2 is fixedly connected to the top of the base 11. The control box 2 is fixedly connected to the outside of the bracket 5. The control box 2 is used to control the operation of the water pump 3. It contains a variety of controllers, which are existing technologies and will not be described in detail here. A raw water tank 1 is fixedly connected to the top of the base 11 to store groundwater. An aeration pump 4 is fixedly connected to the top of the raw water tank 1. A connecting pipe 22 is fixedly connected to the aeration end of the aeration pump 4. Air is introduced into the raw water through the aeration pump 4 to oxidize the metal ions in the raw water to a higher valence state, which is easier for manganese sand to adsorb or precipitate. Multiple casters 13 are installed at the bottom of the base 11 to move the overall position.

[0038] Working principle: First, by disconnecting the buckle 16 and hook 17 on the buckle assembly, the fixing ring 14 and fixing ring 2 15 are disconnected and fixed. Similarly, by connecting the buckle 16 and hook 17, the fixing ring 14 and fixing ring 2 15 can be fixed, thereby fixing the sand filter tank 6, manganese sand tank 7 and carbon filter tank 8. This facilitates the disassembly and installation of the sand filter tank 6, manganese sand tank 7 and carbon filter tank 8, and is beneficial for the assembly, disassembly and transportation of the tank body.

[0039] Secondly, the sliding of the protrusion 21 and the groove 20 at the bottom of the inner liner 19 facilitates the installation of the inner liner 19 between the sand filter tank 6, the manganese sand tank 7, and the carbon filter tank 8. Then, by connecting or disconnecting the buckle 16 and the hook 17, the sealing door 10 is fixed or loosened, thereby fixing or loosening the inner liner 19, which facilitates the removal and installation of the inner liner 19, accelerates the rapid replacement of materials such as manganese sand, and improves the replacement rate.
