Description

Technical Field

[0001] This utility model relates to the technical field of multi-stage treatment systems for turbid circulating water, and in particular to a multi-stage treatment system for turbid circulating water in a steel plant. Background Technology

[0002] The turbidity recirculation multi-stage water treatment system is an advanced water treatment technology primarily used to treat water bodies containing high levels of impurities or pollutants. This system removes pollutants from the water through a multi-stage treatment process, ensuring that the water quality meets the required standards. It has wide applications in various fields such as industrial wastewater treatment, municipal wastewater treatment, and drinking water treatment.

[0003] In existing traditional turbid water treatment equipment, the interception of large particles often relies on fixed filters. After a period of use, these filters are prone to clogging due to the accumulation of impurities, requiring frequent shutdowns for manual cleaning. This not only affects the treatment efficiency but also increases labor costs. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a multi-stage treatment system for turbid circulating water in steel plants.

[0005] This utility model is achieved using the following technical solution: a multi-stage treatment system for turbid circulating water in a steel plant, comprising a turbid circulating water inlet tank, an inlet on the left side of the turbid circulating water inlet tank, a large particle barrier plate fixedly connected to the inner wall of the turbid circulating water inlet tank, a rotating shaft rotatably connected to the inner wall of the large particle barrier plate, a top limiting ring fixedly connected to the surface of the rotating shaft, a bottom limiting ring fixedly connected to the outer wall of the rotating shaft, the top of the bottom limiting ring rotatably connected to the bottom of the large particle barrier plate, a guide fan blade fixedly connected to the outer wall of the rotating shaft, an anti-clogging scraper fixedly connected to the top of the top limiting ring, the anti-clogging scraper slidably connected to the surface of the large particle barrier plate, and an outlet at the bottom of the turbid circulating water inlet tank.

[0006] As a further improvement to the above solution, the bottom of the top limiting ring is rotatably connected to the top of the large particulate matter barrier plate, and several guide fan blades are provided, which are evenly arranged around the rotation axis.

[0007] With the above technical solution, when the turbid circulating water to be treated enters the turbid circulating water inlet tank through the inlet, the turbid circulating water will first flow through the large particle barrier plate, and then flow to the surface of the guide fan blade. The flow of the liquid will drive the guide fan blade to rotate, and the guide fan blade will drive the rotating shaft to rotate synchronously. The rotation of the rotating shaft will further drive the top limit ring and the bottom limit ring to rotate together.

[0008] As a further improvement to the above solution, an adsorption treatment tank is connected to the right side of the outlet. A connecting bolt is slidably connected to the inner wall of the adsorption treatment tank. The connecting bolt penetrates the inner wall of the adsorption treatment tank and extends therethrough. The left side of the connecting bolt penetrates the right side of the turbid circulating water inlet tank and extends therethrough. A connecting nut is threaded onto the outer wall of the connecting bolt. The right side of the connecting nut contacts and is disposed on the surface of the turbid circulating water inlet tank.

[0009] As a further improvement to the above solution, a sealing ring limiting groove is provided on the left side of the adsorption treatment tank, and a sealing ring is fixedly connected to the inner wall of the sealing ring limiting groove. The left side of the sealing ring is in contact with the right side of the turbid circulating water inlet tank.

[0010] As a further improvement to the above solution, a guide pipe is fixedly connected to the inner wall of the adsorption treatment tank, and an activated carbon adsorbent is fixedly connected to the outer wall of the guide pipe. A guide hole is opened on the inner wall of the guide pipe.

[0011] As a further improvement to the above solution, the left side of the guide pipe is connected to the right side of the liquid outlet, several guide holes are opened, the right side of the guide pipe is connected to the main treatment tank, the right side of the main treatment tank is connected to the post-treatment tank, and the bottom of the main treatment tank is fixedly connected to the support leg.

[0012] As a further improvement to the above solution, two sealing ring limiting grooves are provided, and the two sealing ring limiting grooves are symmetrically arranged with the guide pipe as the center. A number of connecting bolts are provided, and the number of connecting bolts are symmetrically arranged with the guide pipe as the center.

[0013] With the above technical solution, after the liquid enters the adsorption treatment tank through the outlet, it will flow upward along the guide pipe; then, the liquid inside the guide pipe will flow through the guide hole to the activated carbon adsorbent inside the adsorption treatment tank, and then flow along the other end of the guide pipe towards the main treatment tank.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention utilizes a system where, after the turbid circulating water to be treated enters the turbid circulating water inlet tank through the inlet, the water flows through a large particle barrier to the surface of the guide fan blades. This allows the large particle barrier to directly intercept large particulate impurities in the water, preventing them from entering subsequent treatment stages and causing equipment blockage or damage. The flow of the liquid drives the guide fan blades, which in turn rotate the rotating shaft. This rotation causes the top and bottom limiting rings to rotate as well. Simultaneously, the top of the rotating shaft drives an anti-clogging scraper to rotate along the top of the large particle barrier, thus cleaning the debris from the top of the barrier. This design requires no additional power source, relying solely on the energy of the water flow itself to complete the cleaning operation, saving energy and improving the economic efficiency of equipment operation.

[0016] This invention involves the liquid entering the adsorption treatment tank through the outlet and flowing upwards along the guide tube. The liquid then flows through the guide tube's openings to the activated carbon adsorbent inside the adsorption treatment tank, and then flows towards the main treatment tank from the other end of the guide tube. Next, the liquid flows from the main treatment tank towards the downstream treatment tank. During this process, the liquid can fully contact the activated carbon adsorbent, extending the contact time and contact area. The activated carbon adsorbent can more efficiently adsorb impurities, odors, and other pollutants in the liquid, significantly improving the purification effect. When the filter needs to be replaced, the connecting nut can be detached from the connecting bolt and the surface of the turbid circulating water inlet tank, and then the connecting bolt can be detached from the inside of the adsorption treatment tank. This allows the entire adsorption treatment tank to be disassembled. Simultaneously, the adsorption treatment tank will cause the sealing ring to detach from the surface of the turbid circulating water inlet tank and the main treatment tank, thus completing the replacement of the filter.

An anti-clogging scraper 8 is fixedly connected to the top of the top limiting ring 5. The anti-clogging scraper 8 is slidably connected to the surface of the large particle barrier plate 3. An outlet 9 is located at the bottom of the turbid circulating water inlet tank 1.

[0028] The top limiting ring 5 is rotatably connected to the top of the large particulate matter barrier plate 3. Several guide fan blades 7 are provided, and the several guide fan blades 7 are evenly arranged around the rotating shaft 4.

[0029] An adsorption treatment tank 10 is connected to the right side of the outlet 9. A connecting bolt 11 is slidably connected to the inner wall of the adsorption treatment tank 10. The connecting bolt 11 penetrates the inner wall of the adsorption treatment tank 10 and extends therethrough. The left side of the connecting bolt 11 penetrates the right side of the turbid circulating water inlet tank 1 and extends therethrough. A connecting nut 12 is threadedly connected to the outer wall of the connecting bolt 11. The right side of the connecting nut 12 contacts and is set on the surface of the turbid circulating water inlet tank 1.

[0030] A sealing ring limiting groove 13 is provided on the left side of the adsorption treatment tank 10. A sealing ring 14 is fixedly connected to the inner wall of the sealing ring limiting groove 13. The left side of the sealing ring 14 is in contact with the right side of the turbid circulating water inlet tank 1.

[0031] An adsorption treatment tank 10 has a flow guide pipe 15 fixedly connected to its inner wall, and an activated carbon adsorbent 16 fixedly connected to the outer wall of the flow guide pipe 15. A flow guide hole 17 is opened on the inner wall of the flow guide pipe 15.

[0032] The left side of the guide pipe 15 is connected to the right side of the liquid outlet 9. Several guide holes 17 are provided. The right side of the guide pipe 15 is connected to the main treatment tank 18. The right side of the main treatment tank 18 is connected to the post-treatment tank 19.

[0034] The implementation principle of a multi-stage treatment system for turbid circulating water in a steel plant in this embodiment is as follows: When the turbid circulating water to be treated enters the turbid circulating water inlet tank 1 through the inlet 2, it flows through the large particle barrier 3 to the surface of the guide fan blade 7. This allows the large particle barrier 3 to directly intercept large particulate impurities in the water, preventing them from entering subsequent treatment stages and causing equipment blockage or damage. The flow of liquid drives the guide fan blade 7, causing the guide fan blade 7 to drive the rotating shaft 4 to rotate. When the rotating shaft 4 rotates, it drives the top limiting ring 5 and the bottom limiting ring 6 to rotate together. At the same time, the top of the rotating shaft 4 drives the anti-clogging scraper 8 to rotate along the top of the large particle barrier 3, thereby cleaning the debris on the top of the large particle barrier 3. This design does not require an additional power source and can complete the cleaning operation by relying on the energy of the water flow itself, saving energy consumption and improving the economic efficiency of equipment operation. Then, the liquid enters the adsorption treatment tank through the outlet 9. After 10, the liquid will flow upward along the guide pipe 15. Then, the liquid inside the guide pipe 15 flows through the guide hole 17 to the activated carbon adsorbent 16 inside the adsorption treatment tank 10, and then flows along the other end of the guide pipe 15 towards the main treatment tank 18. Next, the liquid flows through the main treatment tank 18 towards the post-treatment tank 19. During this process, the liquid can fully contact the activated carbon adsorbent 16, prolonging the contact time and contact area. The activated carbon adsorbent 16 can more efficiently adsorb impurities, odors and other pollutants in the liquid, greatly improving the purification effect of the liquid. When it is necessary to replace the filter device, the connecting nut 12 can be detached from the connecting bolt 11 and the surface of the turbid circulating water inlet tank 1, and then the connecting bolt 11 can be detached from the inside of the adsorption treatment tank 10, so that the adsorption treatment tank 10 can be completely disassembled. At the same time, the adsorption treatment tank 10 will drive the sealing ring 14 to detach from the surface of the turbid circulating water inlet tank 1 and the main treatment tank 18, thereby completing the replacement of the filter device.
