Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a desulfurization circulating water cyclone sedimentation device. Background Technology

[0002] Industrial production generates a large amount of waste gas and waste liquid. According to relevant environmental protection regulations, these waste gases and waste liquids need to be treated. In the treatment of waste gas, the flue gas produced contains a large amount of sulfides. The commonly used method is to use desulfurization towers to desulfurize the flue gas. Common methods in this process include dry desulfurization, spray desulfurization, and wet desulfurization. In the process of wet desulfurization, a large amount of desulfurization water containing sulfides is generated. In order to reduce the demand for water and reduce production costs, the desulfurization water needs to be treated and reused. In the process of treating desulfurization water, the cyclone sedimentation method is often used to disperse and separate sludge in the wastewater.

[0003] During the vortex sedimentation process, large particles of sludge tend to accumulate at the bottom, causing blockage of the suction pipe and affecting the normal operation of the vortex sedimentation. The sludge rotates with the water flow at the bottom and is not easily sucked up by the suction pipe. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0025] Please see Figures 1 to 8 This utility model provides a technical solution: a desulfurization circulating water cyclone sedimentation device, including a cyclone grit chamber 1, a cyclone grit chamber sealing cover 2 fixedly connected to the top of the cyclone grit chamber 1, an inlet pipe 3 fixedly connected to the outer surface of the cyclone grit chamber near the top, a first connecting flange 4 fixedly connected to one end of the inlet pipe 3, a suction pipe 5 fixedly connected to the outer surface of the cyclone grit chamber 1 near the bottom, an upper chamber 24, a conical chamber 25, and a lower chamber 26 opened inside the cyclone grit chamber 1, a sand pump 6 fixedly connected to one end of the suction pipe 5, a discharge pipe 7 fixedly connected to the outlet of the sand pump 6, a second connecting flange 8 fixedly connected to one section of the discharge pipe 7, and the cyclone grit chamber sealing cover 2... A first rotating shaft hole 9 is provided at the top center. A first bearing 10 is fixedly connected to the inner surface of the first rotating shaft hole 9. A rotating cylinder 11 is fixedly connected to the inner ring of the first bearing 10. The rotating cylinder 11 is a hollow structure. An impeller 12 is fixedly connected to one end of the rotating cylinder 11, and a first bevel gear 13 is fixedly connected to the other end of the rotating cylinder 11. Through the coordinated arrangement of the drive motor 19, the rotating cylinder 11, the impeller 12, the upper chamber 24, the conical chamber 25, and the lower chamber 26, the centrifugal force generated by the rotation of the impeller 12 during use can collect the sludge in the desulfurization circulating water into the lower chamber 26, thereby achieving the function of separating the sludge in the desulfurization circulating water and achieving the purpose of collecting the sludge in the lower chamber 26 for extraction.

[0026] A rotating shaft bracket 14 is fixedly connected to the top of the vortex grit chamber sealing cover 2. A second rotating shaft hole 15 is opened on the top of the rotating shaft bracket 14. A second bearing 16 is fixedly connected to the inner surface of the second rotating shaft hole 15. A rotating shaft 17 is fixedly connected to the inner ring of the second bearing 16. A second bevel gear 18 is fixedly connected to one end of the rotating shaft 17 near the top. A drive motor 19 is fixedly connected to the top of the vortex grit chamber sealing cover 2. A drive bevel gear 20 is fixedly connected to the output shaft of the drive motor 19. The drive bevel gear 20, the first bevel gear 13, and the second bevel gear 18 are all connected to the drive bevel gear 20. The external meshing shaft 17 has an annular groove 21 near the bottom on the other end. The inner surface of the annular groove 21 is rotatably connected to the crushing blade 22. Through the cooperation of the drive motor 19, drive bevel gear 20, second bevel gear 18, shaft 17, annular groove 21, crushing blade 22, and lower chamber 26, the shaft 17 can be rotated during use, causing the crushing blade 22 in the annular groove 21 to rotate due to inertia. This crushes the deposited mud and sand, preventing the suction pipe 5 from being blocked by excessively large mud and sand particles.

[0027] A scraper 23 is fixedly connected to the bottom of the rotating shaft 17. Through the coordinated arrangement of the drive motor 19, drive bevel gear 20, second bevel gear 18, rotating shaft 17, scraper 23, and lower chamber 26, the scraper 23 can contact the inner wall of the lower chamber 26 and rotate with the rotating shaft 17 during use, thereby scraping the sludge into the suction pipe 5. This achieves the purpose of preventing the sludge particles from being easily absorbed by the suction pipe 5 because they rotate with the water flow at the bottom.

[0028] During operation, desulfurization circulating water enters the bottom of the vortex grit chamber 1 through the inlet pipe 3. The drive motor 19 is started, and the drive motor 19 drives the bevel gear 20 to rotate, thereby driving the first bevel gear 13 and the second bevel gear 18 to rotate. The first bevel gear 13 drives the rotating drum 11 to rotate, thereby causing the impeller 12 on the rotating drum 11 to rotate. The centrifugal force generated by the rotation of the impeller 12 causes the sludge in the desulfurization circulating water to settle in the lower chamber 26 at the bottom. The second bevel gear 18 drives the rotating shaft 17 to rotate. The crushing blade 22 on the rotating shaft 17 rotates around the annular groove 21 under the action of inertia, crushing the sludge deposited in the lower chamber 26 to prevent the sludge particles from being too large and clogging the suction pipe 5. The scraper 23 on the rotating shaft 17 scrapes the sludge rotating with the water flow in the lower chamber 26 into the interior of the suction pipe 5. The sand pump 6 sucks up the sludge particles in the lower chamber 26 through the suction pipe 5.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
