Description

Technical Field

[0001] This invention relates to the field of mineral mixing technology, and in particular to a mineral powder drum mixing device. Background Technology

[0002] In the steel industry's logistics and transportation sector, iron ore powder, as a key production raw material, often needs to be transported long distances from ports to inland steel enterprises. In extreme low-temperature environments during winter (such as -35 degrees Celsius), iron ore powder is prone to freezing due to moisture, resulting in "frozen sides" and "frozen bottoms"—that is, the iron ore powder severely adheres to the side walls and bottom of the transport vehicle. This not only requires manual intervention for unloading operations, extending operation time and increasing labor costs, but also necessitates the use of thawing storage resources for thawing, causing shortages in thawing storage capacity, reduced transportation efficiency, and creating a vicious cycle of "freezing-stockpiling-reduced efficiency," significantly increasing the operating costs of enterprises.

[0003] To address this issue, the industry generally adopts a technical solution of adding antifreeze to iron ore powder. The core of this solution is to ensure that the antifreeze is evenly mixed with the iron ore powder to prevent freezing in unmixed areas. Existing mixing processes mostly rely on adding antifreeze to the loader bucket and then stirring, or directly sprinkling antifreeze during belt conveyor transport. However, due to limitations in equipment structure and operating methods, problems such as uneven antifreeze dispersion and localized excessively high or low concentrations are prone to occur. Summary of the Invention

[0004] The purpose of this invention is to provide a mineral powder drum mixing device that solves the problems of uneven dispersion and excessively high or low concentration in existing mixing processes mentioned in the background art.

[0005] The technical solution adopted in this invention is as follows: A mineral powder drum mixing device includes a first frame, a second frame, and a third frame. A first hopper is installed on the first frame, and a first discharge valve is connected to the lower port of the first hopper. An inclined duckbill pipe is connected to the lower port of the first discharge valve. A first support is installed on the top surface of the duckbill pipe, and a variable diameter main material pipe is installed on the first support. The small diameter port of the main material pipe is used to connect to an air pipe, and a branch pipe is connected to the side wall of the main material pipe. An inclined conveying mechanism is connected to the lower end of the first frame. The conveying mechanism is located on the second frame, and a screening and mixing mechanism is installed on the conveying mechanism. A second hopper is installed on the third frame, and a second discharge valve is installed at the lower port of the second hopper. A three-way pipe is installed at the lower port of the second discharge valve. A first motor is installed at one end of the three-way pipe, and a flexible hose connected to the branch pipe is installed at the other end. A shaftless auger driven by the first motor is installed inside the flexible hose.

[0006] Both the first hopper and the second hopper are equipped with support bases on their side walls, and a vibration motor is mounted on the support base.

[0007] A third roller assembly is installed on the support frame. The third roller assembly includes a third carrier plate. A first short shaft is installed in the middle of the third carrier plate. A V-shaped fourth carrier plate is rotatably connected to the first short shaft. A first roller seat and a second roller seat are symmetrically arranged on the fourth carrier plate. A first rotating roller is rotatably connected between the two second roller seats with gaps. A fourth rotating roller with a cylindrical section and a conical section is rotatably connected between the first roller seat and the second roller seat with gaps. The two fourth rotating rollers and one first rotating roller form a V-shaped structure. Second telescopic rods connected to the support frame are hinged at both ends of the fourth carrier plate.

[0008] The lower panel of the eighth carrier plate is equipped with a track, a slide plate is slidably connected to the track, a wheel seat with guide rollers is connected to the bottom surface of the slide plate, and a second spring is installed between the wheel seat and the lower panel of the eighth carrier plate.

[0009] A tensioning mechanism is installed on the support frame. The tensioning mechanism includes two symmetrically arranged feet, each with a support leg. A first housing is connected to the support leg, and a shaft is rotatably connected inside the first housing. The portion of the shaft inside the first housing is connected to a shaft tube, and a first worm gear is connected to the shaft tube. The first worm gear meshes with a first worm driven by a screw head. Two symmetrically arranged springs are hinged between the shaft tube, the first housing, and the first worm gear. A support arm is connected to the portion of the shaft outside the first housing, and a tensioning roller that rolls in contact with the outer surface of the conveyor belt is rotatably connected between the two support arms.

[0010] The support frame is equipped with two symmetrically arranged eighth bearing seats, and a brush roller driven by a sixth motor is installed between the two eighth bearing seats. The brush roller makes rolling contact with the outer surface of the conveyor belt.

[0011] A second support is mounted on the side of the housing, and a first bearing plate is mounted on the second support. A second housing is connected to the first bearing plate, and a second worm gear is rotatably connected inside the second housing. The second worm gear meshes with a second worm wheel driven by a seventh motor. A splined shaft is slidably connected to the second worm wheel, and a sampling bowl is connected to one end of the splined shaft. Two symmetrically arranged second bearing plates are connected to the first bearing plate, and a second guide rail is mounted on the second bearing plate. A second slide with a moving platform is slidably connected to the second guide rail. A ninth bearing seat and a ball bearing slide are connected to the moving platform and are rotatably connected to the tail end of the splined shaft. A third bearing plate with a lead screw is mounted on the first bearing plate. The lead screw is adapted to the ball bearing slide and is driven by an eighth motor. A fourth bearing plate with a guide tube is also mounted on the first bearing plate. An electrically controlled valve with a material gate is connected to the lower end of the guide tube.

[0012] The beneficial effects of this invention are as follows: This mineral powder drum mixing equipment can achieve continuous and uniform mixing of iron ore powder and antifreeze through the rotation of the screening and mixing mechanism combined with airflow-assisted pushing. The vibration motor acting on the hopper at regular intervals can effectively prevent material bridging or hanging, ensuring smooth and stable feeding. The conveying mechanism adopts a conveying belt with V-grooves, combined with a double-drive drum and idler roller assembly, which can not only prevent material slippage during conveying, but also achieve automatic belt correction through the conical section of the idler roller and the telescopic rod structure, reducing manual maintenance costs. The screen knocking structure can promptly clean the screen hole blockage and maintain screening and mixing efficiency. The labyrinthine path of the discharge end shell can perform secondary stirring of the mixture, further improving the mixing uniformity. The sampling mechanism can conveniently obtain the mixture sample for real-time monitoring of product quality. The tensioning mechanism can flexibly adjust the tension of the conveying belt to prevent belt slippage. The brush roller can promptly clean the material adhering to the belt surface, reducing material waste and the probability of belt deviation. The overall device can significantly improve the mineral mixing efficiency and quality, meeting the needs of large-scale production in the plant. Attached Figure Description

Benefits: Achieves continuous and uniform mixing of iron ore powder and antifreeze, improves mixing efficiency, reduces manual labor intensity, and meets the large-scale material mixing needs of the plant.

[0054] like Figure 3As shown, as an optimization of Embodiment 1, support seats 18 are installed on the side walls of the first hopper 4 and the second hopper 12. A vibration motor 19 is installed on the support seat 18. The vibration motor 19 is turned on periodically to prevent material bridging or adhesion to the walls.

The discharging end of the support frame 20 is equipped with… Two symmetrically arranged third bearing seats 29 are provided, and a second drive roller 30 is rotatably connected to the third bearing seat 29. The surface of the second drive roller 30 has a second toothed tube 31. The first drive roller 24 and the second drive roller 30 are connected by a second belt drive 32. A conveyor belt 33 is installed between the second drive roller 30 and the redirecting roller 22. The outer surface of the conveyor belt 33 has a groove 34, which is V-shaped and prevents material from sliding down. The top surface of the support frame 20 is equipped with equally spaced first idler roller assemblies 35, which support the conveyor belt 33 and roll in contact with the inner surface of the conveyor belt 33.

Movement Process: The second motor 27 drives the first drive roller 24 to rotate via the first belt drive 26. The first drive roller 24 drives the second drive roller 30 to rotate via the second belt drive 32, thereby driving the conveyor belt 33 to rotate. Material falls onto the conveyor belt 33, and the first idler assembly 35 and the second idler assembly 36 support the conveyor belt 33. Beneficial Effects: The V-shaped groove 34 prevents material from slipping, the dual drive rollers increase the driving force of the conveyor belt 33, and the idler assembly ensures smooth belt operation, improving conveying efficiency and stability.

[0056] like Figure 9As shown, as an optimization of Embodiment 1, the first idler assembly 35 includes a first carrier plate 37 mounted on a support frame 20. The cross-sectional shape of the first carrier plate 37 is angular. Two symmetrically arranged first roller seats 38 are mounted on the first carrier plate 37. The shape of the first roller seats 38 is bent. Two symmetrically arranged second roller seats 39 are mounted on the first carrier plate 37. The shape of the second roller seats 39 is inverted U-shaped. A first rotating roller 40 is rotatably connected between the two second roller seats 39 and the gap between the first roller seats 38 and the second roller seats 39. A second rotating roller 41 is rotatably connected between the two second rotating rollers 41 and one first rotating roller 40 to form a V-shaped structure for supporting the conveyor belt 33. Technical problem: Solve the problem of unstable support and easy deviation of the conveyor belt 33.

[0058] like Figure 11 and 12As shown, as an optimization of Embodiment 1, the screening and mixing mechanism 11 includes a second carrier 44 and a third carrier 45 mounted on a support frame 20. The second carrier 44 and the third carrier 45 are inverted U-shaped. The surface of the second carrier 44 is located at the feeding end of the conveyor belt 33, and the surface of the third carrier 45 is located at the middle of the conveyor belt 33. A fifth bearing seat 46 is mounted on the second carrier 44 and the third carrier 45. A first rotating shaft 47 is rotatably connected to the fifth bearing seat 46 through a gap.

The free ends of the vertical rods 50 are connected in series by horizontal rods 51. The two ends of the horizontal rods 51 are connected to rings 52, and screens 53 are installed in the gap between two rings 52. The screens 53 at the feeding end have a discharge port 54; it also includes support rods 55 mounted on the support frame 20. The support rods 55 on both sides are symmetrically arranged, and baffles 56 are connected to the top surface of the support rods 55. Two baffles 56 form a V-shape, so that the undersize material falls onto the conveyor belt 33. Technical problem: To solve the problem of insufficient mixing of iron ore powder and antifreeze, and the easy scattering of the mixed material outside the conveyor belt 33. Movement Process: The third motor 49 drives the first rotating shaft 47 to rotate via the third belt drive 48. The first rotating shaft 47 drives the screen 53 to rotate. Iron ore powder and antifreeze enter the rotating screen 53 and mix. The undersize material falls onto the conveyor belt 33, and the V-shaped baffle 56 guides the material onto the conveyor belt 33. Beneficial Effects: The rotation of the screen 53 improves the uniformity of material mixing, and the baffle 56 prevents material from scattering, ensuring that all the mixed materials enter the conveyor belt 33.

[0059] like Figure 13 As shown, as an optimization of Embodiment 1, a fourth carrier 57 is installed on the top surface of the second carrier 44. The fourth carrier 57 is inverted U-shaped. A sixth bearing seat 58 is installed on the fourth carrier 57 and the first hopper 4. A second rotating shaft 59 is rotatably connected to the sixth bearing seat 58 through a gap. The second rotating shaft 59 is connected to the first rotating shaft 47 through a fourth belt drive 60. A staggered belt seat 61 is installed on the side wall of the second rotating shaft 59. A belt body 62 is installed on the belt seat 61. The belt body 62 is used to strike the screen 53 and clear the blockage in the screen holes. Technical problem: Solving the problem that the screen holes of the screen 53 are easily blocked by materials, resulting in a decrease in screening and mixing efficiency. Movement process: The first rotating shaft 47 drives the second rotating shaft 59 to rotate through the fourth belt drive 60. The second rotating shaft 59 drives the belt seat 61 and the belt body 62 to rotate. The rotating belt body 62 strikes the screen 53. Beneficial effects: By tapping and shaking off the material clogging the screen holes, the screen 53 is kept clear, maintaining stable screening and mixing efficiency.

[0060] like Figure 14 and 15As shown, as an optimization of Embodiment 1, the support frame 20 at the discharge end is equipped with a second carrier plate 63, and a vertical shaft 64 is mounted on the second carrier plate 63. A housing 65 is rotatably connected to the vertical shaft 64. The housing 65 is used to receive the mixed material discharged from the conveyor belt 33. The housing 65 is tubular in shape, and staggered third rotating shafts 66 are installed inside the housing 65. Several third rotating shafts 66 form a maze-like path inside the housing 65. Mixing plates 67 arranged at equal angles are connected to the side walls of the third rotating shafts 66. The third rotating shafts 66 are driven by a fourth motor 68. A first telescopic rod 69 is hinged to the side wall of the housing 65. The first telescopic rod 69 is arranged horizontally, and its tail end is hinged to the support frame 20. Technical problem: Solving the problem of insufficient mixing uniformity of the mixed material before discharge and the inability to adjust the discharge direction. Movement Process: The conveyor belt 33 transports the material to the housing 65. The fourth motor 68 drives the third rotating shaft 66 to rotate, which in turn drives the mixing plate 67 to rotate. As the material travels through the maze-like path within the housing 65, it is further agitated by the mixing plate 67. The first telescopic rod 69 extends and retracts, causing the housing 65 to rotate and adjust the discharge direction. Beneficial Effects: Secondary mixing of the material improves uniformity, and the adjustable discharge direction meets different stacking requirements.

[0061] like Figure 16 and 17 As shown, as an optimization of Embodiment 1, a third idler assembly 70 is installed on the support frame 20.
