Abstract
Description
Technical Field
[0001] This utility model relates to the field of molybdenum tailings slurry transportation technology, and more specifically, to anti-scaling guide vanes for molybdenum tailings slurry transportation pipelines. Background Technology
[0002] Molybdenum tailings slurry is a waste product generated during the beneficiation of molybdenum ore. It mainly consists of solid particles, water, and residual reagents remaining after the ore has been processed through crushing, grinding, flotation, and other processes to extract molybdenum concentrate.
[0003] In actual use, because molybdenum tailings slurry contains some particles, it is easy for the slurry to precipitate inside the conveying pipeline, forming a scale layer. This will accelerate pipeline corrosion and wear, shorten service life, and long-term accumulation will block the pipeline, leading to a significant increase in flow resistance and thus reducing conveying efficiency. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides anti-scaling guide vanes for molybdenum tailings slurry conveying pipelines to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: A scale-preventing guide vane for a molybdenum tailings slurry conveying pipeline includes a conveying pipeline, a connecting pipe at the top of the conveying pipeline, a flow guiding component installed inside the conveying pipeline, and an adjusting mechanism installed inside the connecting pipe. The flow guiding assembly includes a servo motor mounted on one side of the conveying pipe. A rotating shaft is fixedly connected to the output end of the servo motor. A fixed disk is fixedly connected to the outside of the rotating shaft. Multiple vortex blades are fixedly connected to the outside of the fixed disk. A flow guiding cone is fixedly connected to the outside of the rotating shaft. Three first flow guiding blades and two second flow guiding blades are fixedly connected to the outside of the flow guiding cone. The second flow guiding blades are mounted on one side of the first flow guiding blades. The three first flow guiding blades and two second flow guiding blades are arranged in a circular array on the outside of the flow guiding cone. Three fixed rods are fixedly connected to the outside of the rotating shaft. A scraper is fixedly connected to one end of each fixed rod. One side of the scraper is adapted to the inner wall of the conveying pipe.
[0006] By adopting the above technical solution, eddies can be generated inside the conveying pipeline, which can guide the rapid flow of molybdenum tailings slurry and help improve conveying efficiency.
[0007] As a further description of the above technical solution: the adjustment mechanism includes multiple support frames, the support frames are fixedly connected to the outside of the connecting pipe, a connecting block is fixedly connected to the top of the flow guide, a shaft support is hinged to the outside of the connecting block, a protective shell is fixedly connected to the outside of the shaft support, and the protective shell is fixedly connected to the inner wall of the conveying pipe.
[0008] By adopting the above technical solution, the opening and closing of multiple guide hoods can be adjusted according to the actual flow rate of molybdenum tailings slurry, which helps the molybdenum tailings slurry to smoothly enter the conveying pipeline.
[0009] The technical effects and advantages of this utility model are as follows: 1. By setting up a flow guiding component, compared with the existing technology, the fixed disk drives multiple rotating shafts to generate vortices, which keeps the solid particles in the molybdenum tailings slurry in a suspended state, reducing the probability of particle settling. The rotation of the three first and second flow guiding blades can guide the slurry to form a spiral flow, so as to facilitate the rapid transportation of molybdenum tailings slurry. At the same time, the three scrapers scrape the inner wall of the transportation pipeline during transportation, which can further inhibit scaling, thereby improving the transportation efficiency. 2. By setting an adjustment mechanism, compared with the existing technology, multiple cylinders can drive one end of the guide shroud to swing, so that multiple guide shrouds are distributed radially, which can divide the vertically falling tailings slurry into multiple fine streams, and can adjust the guiding effect according to the actual flow rate, which helps the molybdenum tailings slurry to enter the conveying pipeline smoothly.

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.
[0018] The embodiments disclosed in this application are as follows: Figure 1-6 The molybdenum tailings slurry conveying pipeline shown has anti-scaling guide vanes, including a conveying pipeline 1, a connecting pipeline 11 connected to the top of the conveying pipeline 1, a flow guiding component installed inside the conveying pipeline 1, and an adjustment mechanism installed inside the connecting pipeline 11. The flow guiding assembly includes a servo motor 2, which is installed on one side of the conveying pipe 1. A rotating shaft 3 is fixedly connected to the output end of the servo motor 2. A fixed disk 4 is fixedly connected to the outside of the rotating shaft 3. Multiple vortex blades 10 are fixedly connected to the outside of the fixed disk 4. A flow guiding cone 5 is fixedly connected to the outside of the rotating shaft 3. Three first flow guiding blades 6 and two second flow guiding blades 7 are fixedly connected to the outside of the flow guiding cone 5. The second flow guiding blades 7 are installed on one side of the first flow guiding blades 6. The three first flow guiding blades 6 and second flow guiding blades 7 are arranged in a ring array on the outside of the flow guiding cone 5. Three fixed rods 8 are fixedly connected to the outside of the rotating shaft 3. A scraper 9 is fixedly connected to one end of each fixed rod 8. One side is adapted to the inner wall of the conveying pipe 1. The rotating shaft 3 is driven by the servo motor 2 to rotate, so that the rotating shaft 3 can drive the fixed disk 4 and the guide cone 5 to rotate. The fixed disk 4 can drive multiple vortex blades 10 to generate vortices inside the conveying pipe 1, so that the solid particles in the molybdenum tailings slurry remain in a suspended state, thereby reducing sedimentation. The guide cone 5 can drive the three first guide blades 6 and the second guide blades 7 to rotate, thereby guiding the slurry to form a spiral flow, so as to facilitate the flow of molybdenum tailings slurry. At the same time, the three scrapers 9 can follow the rotation of the rotating shaft 3 to scrape the conveying pipe 1, which can further inhibit scaling.
[0019] Reference Figure 5 and 6 As shown, the adjustment mechanism includes multiple support frames 12, which are fixedly connected to the outside of the connecting pipe 11. A connecting block 15 is fixedly connected to the top of the flow guide shroud 14, and a shaft support 16 is hinged to the outside of the connecting block 15. A protective shell 17 is fixedly connected to the outside of the shaft support 16, and the protective shell 17 is fixedly connected to the inner wall of the conveying pipe 1. By hinged between the connecting block 15 and the inner side of the shaft support 16, the shaft support 16 can support one end of the flow guide shroud 14, so that the cylinder 13 can push one end of the flow guide shroud 14 to swing and adjust. This allows the multiple flow guide shrouds 14 to be radially distributed and the flow guiding effect can be adjusted according to the actual flow rate, which helps the molybdenum tailings slurry to enter the conveying pipe 1 smoothly.
[0020] Working principle of this utility model: This utility model is designed with anti-scaling guide vanes for molybdenum mine tailings slurry conveying pipelines. The specific structure is shown in the attached instruction manual. Figure 1-6 As shown, in this technical solution, through the cooperation between various structures, when it is necessary to transport molybdenum tailings slurry, the connecting pipe 11 is first connected to the molybdenum tailings slurry pipe. Then, the opening and closing angles of multiple guide hoods 14 are adjusted according to the flow rate of the molybdenum tailings slurry. At the same time, multiple cylinders 13 are activated. The cylinders 13 can drive the bottom of the guide hood 14 to move. The guide hood 14 is hinged to the inner side of the shaft support 16 through the connecting block 15, so that the shaft support 16 can support the top of the guide hood 14, so that the tilt angle of the guide hood 14 can be adjusted to adapt to the flow rate of the molybdenum tailings slurry. Then, servo motor 2 is started, which drives shaft 3 to rotate. Shaft 3 drives fixed disk 4 and guide cone 5 to rotate. Fixed disk 4 drives multiple vortex blades 10 to rotate, which generates vortices, thereby reducing the sedimentation and accumulation of molybdenum tailings slurry inside the conveying pipe 1. At the same time, guide cone 5 drives three first guide blades 6 and second guide blades 7 to rotate. The three first guide blades 6 guide the molybdenum tailings slurry. The spiral action of the three second guide blades 7 facilitates the rapid movement of molybdenum tailings slurry towards one end of the conveying pipe 1, which can drive the flow of molybdenum tailings slurry and transport it quickly. Meanwhile, shaft 3 can drive scraper 9 to scrape the inner wall of conveying pipe 1 through three fixed rods 8. Thus, while conveying, the three scraper 9 can clean the inner wall of conveying pipe 1, thereby reducing the sedimentation and adhesion of molybdenum tailings slurry on the inner wall of conveying pipe 1.
