Description

Technical Field

[0001] This utility model relates to the field of phosphate rock slurry transportation, specifically to an environmentally friendly phosphate rock slurry transportation pipeline. Background Technology

[0002] When phosphate rock slurry is transported in an open-air square tank, toxic gases from the slurry are directly released into the air, severely impacting air quality in the production and processing area. Long-term transport of phosphate rock slurry leads to the deposition of solid impurities on the inner wall of the square tank. External impurities also fall into the tank and mix with the phosphate rock slurry, affecting the transport quality. A Chinese patent (authorization announcement number CN 205781700 U) discloses an environmentally friendly phosphate rock slurry transport pipeline. This patented technology prevents impurities around the pipeline from falling into the phosphate rock slurry during transport. Simultaneously, the insulation layer wrapped around the outer wall of the pipeline prevents the temperature of the phosphate rock slurry inside from being affected by external temperatures, ensuring the transport quality. However, during transport, particulate matter remains at the bottom of the pipeline, accumulating over time and affecting the transport efficiency. Therefore, those skilled in the art have provided an environmentally friendly phosphate rock slurry transport pipeline to solve the problems mentioned in the background. Utility Model Content

[0003] To solve the above technical problems, this utility model provides an environmentally friendly phosphate slurry conveying pipeline, including a pipeline, an anti-corrosion layer on the inner wall of the pipeline, an insulation layer on the outer surface of the pipeline, an exhaust pipe installed at the upper end of the pipeline, an exhaust fan installed at the upper end of the exhaust pipe, a purification mechanism installed at one end of the exhaust fan, and a mating hole opened at the lower end of the pipeline, with an arc-shaped pipe installed inside the mating hole.

[0004] A rotating shaft is installed inside the arc-shaped tube, and a spiral conveyor plate is installed on the outer surface of the rotating shaft. A bevel gear one is installed on the right side of the outer surface of the rotating shaft. Bevel gear one and bevel gear two mesh with each other. A main shaft is installed at the lower end of bevel gear two. A motor is installed at the lower end of the main shaft. A collection port is opened at the lower left side of the arc-shaped tube. A collection frame is set at the lower end of the collection port. A snap-fit ​​mechanism is installed on the side of the collection frame. The collection frame cooperates with the arc-shaped tube through the snap-fit ​​mechanism.

[0005] Preferably, the two ends of the rotating shaft are rotatably connected to bearing seats, and the bearing seats are fixedly connected to the bottom of the arc-shaped tube through support blocks.

[0006] Preferably, the snap-fit ​​mechanism includes a fixed block and a mating block. The two fixed blocks are symmetrically fixed on the side of the collection frame. A cavity is provided inside the fixed block. A movable block is slidably connected inside the cavity. Springs are symmetrically installed on the outer end of the movable block.

[0007] Preferably, a pull rod is installed at the outer end of the movable block, and the pull rod passes through the fixed block to fix the pull block. A pull ring is installed at the outer end of the pull block, and a locking block is installed at the inner end of the pull block.

[0008] Preferably, the two mating blocks are symmetrically fixed to the sides of the arc-shaped tube, and a slot is opened at the outer end of the mating block.

[0009] The technical effects and advantages of this utility model are as follows:

[0010] This invention utilizes an arc-shaped tube to allow particles at the bottom of the pipe to fall into the tube. A motor drives a spiral conveyor to rotate, pushing the particles forward through the tube and into a collection frame. This ensures the cleanliness of the bottom of the pipe and prevents particle accumulation inside the pipe from affecting the transport of phosphate slurry. Furthermore, a snap-fit ​​mechanism allows for easy disassembly and cleaning of the collection frame, making the process convenient, quick, and labor-saving. Attached Figure Description

Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0020] Please see Figures 1-4This embodiment provides an environmentally friendly phosphate slurry conveying pipeline, including a pipeline 1. The inner wall of the pipeline 1 is provided with an anti-corrosion layer, and the outer surface of the pipeline 1 is installed with an insulation layer. An exhaust pipe 2 is installed at the upper end of the pipeline 1, and an exhaust fan 3 is installed at the upper end of the exhaust pipe 2. A purification mechanism 4 is installed at one end of the exhaust fan 3. A mating hole 5 is opened at the lower end of the pipeline 1, and an arc-shaped tube 6 is installed inside the mating hole 5. A rotating shaft 7 is installed inside the arc-shaped tube 6, and a spiral conveying plate 8 is installed on the outer surface of the rotating shaft 7, with the spiral conveying plate 8 contacting the inner wall of the arc-shaped tube 6. Bearing seats 9 are rotatably connected to both ends of the rotating shaft 7, and the bearing seats 9 are fixedly connected to the bottom of the arc-shaped tube 6 via support blocks. A bevel gear 10 is installed on the right side of the outer surface of the rotating shaft 7, and the bevel gear 10 meshes with a bevel gear 2 11. A main shaft 12 is installed at the lower end of the bevel gear 2 11, and the main shaft 12 is rotatably connected to the inside of the arc-shaped tube 6. 2. A motor 13 is installed at the lower end. A collection port 14 is opened on the lower left side of the arc tube 6. A collection frame 15 is set at the lower end of the collection port 14. A snap-fit ​​mechanism 16 is installed on the side of the collection frame 15. The collection frame 15 cooperates with the arc tube 6 through the snap-fit ​​mechanism 16. The snap-fit ​​mechanism 16 includes a fixing block 17 and a mating block 24. Two fixing blocks 17 are symmetrically fixed on the side of the collection frame 15. A cavity is set inside the fixing block 17. A moving block 18 is slidably connected inside the cavity. A spring 20 is symmetrically installed on the outer end of the moving block 18. A pull rod 19 is installed on the outer end of the moving block 18. The pull rod 19 passes through the fixing block 17 and is fixedly connected to the pull block 21. A pull ring 23 is installed on the outer end of the pull block 21. A locking block 22 is installed on the inner end of the pull block 21. Two mating blocks 24 are symmetrically fixedly connected to the side of the arc tube 6. A locking groove 25 is opened on the outer end of the mating block 24.

[0021] The working principle of this utility model is as follows: the toxic gas inside the pipe 1 is drawn into the purification mechanism 4 by the exhaust fan 3 and the exhaust pipe 2 for purification. When the pipe 1 is transporting phosphate rock slurry, the particles in the phosphate rock slurry will be affected by gravity and remain at the bottom of the pipe 1, causing accumulation, which will affect the transportation effect of the phosphate rock slurry.

[0022] By setting up the arc-shaped tube 6, the particles at the bottom of the pipe 1 fall into the arc-shaped tube 6. The motor 13 is controlled to work. The motor 13 drives the bevel gear 11 to rotate through the main shaft 12. The bevel gear 11 meshes with the bevel gear 10 to drive the rotating shaft 7 to rotate. The rotating shaft 7 drives the spiral conveyor plate 8 to rotate. The spiral conveyor plate 8 pushes the particles in the arc-shaped tube 6 forward, so that the particles fall into the collection frame 15 through the collection port 14, ensuring that the bottom of the pipe 1 is clean and avoiding the accumulation of particles inside the pipe 1, which would affect the transportation of phosphate slurry.

[0023] When it is necessary to clean the particles in the collection box 15, the pull ring 23 drives the pull block 21, pull rod 19 and moving block 18 to move and compress the spring 20. At the same time, the pull block 21 drives the locking block 22 to leave the locking slot 25, thereby disassembling the collection box 15 for cleaning.
