Description

Technical Field

[0001] The utility model relates to the technical field of tailings transportation, in particular to a transportation device for high-concentration tailings processing. Background Art

[0002] When selecting iron ore concentrate, a concentration tank is often used to concentrate the tailings, and then the high-concentration tailings are transported. Due to the long distance transportation to the underground filling site, the filling line in some areas is too long, and the tailings slurry does not have enough pressure by gravity, so a booster device is needed to boost the slurry for transportation.

[0003] A high-concentration tailings slurry pipeline conveying and pressurizing device is disclosed in Chinese patent CN216950473U. The high-concentration tailings slurry pipeline conveying and pressurizing device drives the dragon blades on the rotating rod to rotate through a servo motor. The rotating dragon blades can push the tailings slurry, thereby increasing the pressure in the pipeline, and can quickly convey the tailings slurry and can convey materials with different viscosities.

[0004] However, compared with the existing technology in the related field, since the Jiaolong blades are fixed and rotating, and the slurry has poor fluidity and high viscosity, some block slurry will adhere to the Jiaolong blades, which will increase the load on the motor and cause blockage when the device is running for a long time.

[0033] like Figure 1-7As shown, a conveying device for high-concentration tailings treatment comprises a mounting pipe 1, both ends of which are fixedly provided with flanges 101. The flanges 101 can be used to facilitate the installation and connection of the mounting pipe 1 with the tailings conveying pipeline. A fixing cylinder 2 is fixedly installed inside the mounting pipe 1, and a first rotating rod 3 is rotatably connected at the center of the fixing cylinder 2. A base 8 is provided with a first rotating hole at the position of the first rotating rod 3. A bearing is embedded inside the first rotating hole. The bearing can reduce the friction force of the first rotating rod 3 when rotating, and improve the stability of the first rotating rod 3 when rotating. A first bevel gear 4 is fixedly provided at the bottom end of the first rotating rod 3, and the first bevel gear 4 is meshingly connected with a second bevel gear 5. The second bevel gear 5 is meshingly connected with the first bevel gear 4. A second rotating rod 6 is fixedly provided at the center of the bevel gear 5, and the center of the second rotating rod 6 corresponds to the center of the mounting tube 1. The fixed cylinder 2 is provided with second rotating holes at both ends of the second rotating rod 6, and the inside of the second rotating holes is inlaid with bearings. The bearings can reduce the friction force when the second rotating rod 6 rotates, and improve the stability of the second rotating rod 6 when it rotates. A swing component 7 is provided at the end of the second rotating rod 6. The mounting tube 1 is located at the top of the fixed cylinder 2 and fixed with a base 8. A motor 9 is fixedly installed at the top of the base 8 corresponding to the center of the fixed cylinder 2. The output end of the motor 9 passes through the base 8 and is connected to the first rotating rod 3. The motor 9 can be used to control the first rotating rod 3 to rotate at different speeds;

[0034] The swing assembly 7 includes a fixed column 701 fixedly connected to the second rotating rod 6, a sliding groove 702 is provided inside the fixed column 701, a notch is opened at the end of the fixed column 701 away from the second rotating rod 6, a ball 703 is movably connected inside the sliding groove 702, the ball 703 and the sliding groove 702 are matched with the elastic member 704, a third rotating rod 705 adapted to the notch is fixedly provided on the side of the ball 703 close to the notch, the diameter of the ball 703 is larger than the diameter of the notch, the notch can be used to prevent the ball 703 from detaching from the fixed column 701, and the swing amplitude of the third rotating rod 705 can be constrained, and a spiral auger 706 is fixedly provided on the end of the third rotating rod 705 away from the ball 703.

[0035] The working process is as follows:

[0036] S1. When in use, one side of the fixed tube 2 of the mounting tube 1 is the feed port. When the material enters the mounting tube 1, the impact force of the material will cause the spiral auger 706 to move toward the discharge port of the mounting tube 1 (at this time, the impact force of the material is greater than the elastic force of the elastic member 704, so that the spiral auger 706 can cause the ball 703 to slide inside the sliding groove 702 through the third rotating rod 705);

[0037] S2. When the spiral auger 706 moves toward the discharge port of the installation pipe 1, the notch no longer constrains the third rotating rod 705;

[0038] S3, the first rotating rod 3 is controlled to rotate by starting the motor 9, and then the first rotating rod 3 can drive the second rotating rod 6 to rotate through the meshing of the first bevel gear 4 and the second bevel gear 5, and then the second rotating rod 6 drives the swing assembly 7 to rotate;

[0039] S4. When the notch no longer constrains the third rotating rod 705, the spiral auger 706 will rotate irregularly, thereby improving the conveying effect of the spiral auger 706 on the material. At the same time, the spiral auger 706 can shake off the attachments on its surface when swinging;

[0040] S5. By utilizing the elastic member 704, the sliding distance of the spiral auger 706 can be changed in real time with the impact force of the slurry. Then, by utilizing the cooperation between the third rotating rod 705 and the slot, the swing amplitude of the spiral auger 706 can be changed in real time with the impact force of the slurry (the greater the impact force of the slurry, the smaller the swing amplitude of the spiral auger 706, and the smaller the impact force of the slurry, the smaller the swing amplitude of the spiral auger 706).

[0041] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
