Abstract

[0019] Reference Figure 1 The utility model discloses a manganese dioxide drying device, including a tank body 11, which is a circular ring structure. A feed port 12 is provided on the top of the tank body 11, and the feed port 12 is funnel-shaped. A discharge port 14 is provided at the bottom of the tank body 11, and the discharge port 14 is provided with a plate valve for switching. A plurality of air inlet pipes 13 for introducing dry gas are provided in the tank body 11, and a gas drying method is used. An auger conveyor 22 and a guide sleeve 31 surrounding the auger conveyor 22 are provided in the tank body 11, and a motor 21 for driving the auger conveyor 22 to rotate and an exhaust port for discharging moisture are provided on the top of the tank body 11. The guide sleeve 31 is suspended from the top of the tank body 11 by a plurality of connecting rods, and three connecting rods are provided, and the three connecting rods are evenly distributed around the center of the guide sleeve 31. The top and bottom of the auger conveyor 22 extend out of the top and top of the guide sleeve 31, the bottom of the guide sleeve 31 does not contact the tank body 11, and the top of the guide sleeve 31 is sleeved with a conical dispersion plate 32. The auger conveyor 22 lifts the manganese dioxide powder inside the tank body 11 to a high place and scatters the manganese dioxide powder at a high place. When the manganese dioxide powder falls into the dispersion plate 32, it slides away from the auger conveyor 22, and the manganese dioxide powder is fully exposed to the dry hot air and is dried.
[0020] The auger conveyor 22 cyclically lifts the manganese dioxide powder in the middle and re-scatters it from the top, which is conducive to the dry hot air to fully dry the material, and the dried material is accumulated near the inner wall of the tank body 11. As the material in the middle of the tank body 11 is gradually sucked away, the dried material at the outermost side gathers in the middle again, and the drying cycle is repeated. The equipment has a simple structure, few moving parts, and a good drying effect.
[0021] As an improvement of the above solution, the inner wall of the bottom of the tank body 11 is set to be funnel-shaped, and the lowest point is located below the auger conveyor 22, and the discharge port 14 is located directly below the auger conveyor 22. The above solution is adopted to facilitate material gathering, and the bottom of the auger conveyor 22 is basically in contact with the bottom of the tank body 11, so as to lift and transfer the manganese dioxide powder as much as possible.
[0022] As an improvement of the above scheme, the inclination angle of the dispersion plate 32 is 50-60°, which facilitates the sliding of the manganese dioxide powder; the radius of the dispersion plate 32 is 1 / 2 to 2 / 3 of the radius of the tank body 11, so that the falling manganese dioxide powder is concentrated on the inner wall of the tank body 11. When the manganese dioxide powder in the middle of the tank body 11 is sucked away, the material on the outside gathers again in the middle.
[0023] As an improvement of the above scheme, a vibrator 41 is provided on the outside of the funnel structure of the tank body 11. When the vibrator 41 is working, the manganese dioxide powder attached to the inclined surface is shaken off. An inspection hole 42 and a baffle are provided on the side of the tank body 11. A plurality of the inspection holes 42 are arranged at intervals around the tank body 11, and a plurality of the vibrators 41 are evenly attached to the outside of the funnel structure, ensuring that a plurality of vibrators 41 close to the inspection hole 42 can be installed.
[0024] As an improvement of the above solution, the exhaust port is provided with a filter screen for preventing the manganese dioxide powder from overflowing, and the feed port 12 is provided with a one-way opening plate valve.
[0025] As an improvement of the above solution, several air inlet pipes 13 are arranged vertically, and exhaust holes are set at different heights on the side of each air inlet pipe 13. Further, each air inlet pipe 13 is located at a position close to the inner wall of the tank body 11, and several exhaust holes face the auger conveyor 22. The above solution ensures uniform blowing.
[0026] As an improvement of the above scheme, a plurality of circular holes are evenly arranged on the side of the guide sleeve 31, the wall thickness of the guide sleeve 31 is 1-2 mm, and the diameter of each circular hole is 1-1.6 mm. With the above scheme, when the dry hot air enters the tank body 11, part of the air can also enter the guide sleeve 31, so as to achieve the purpose of conveying materials while drying them. In addition, when the auger conveyor 22 rotates, a small amount of materials will be thrown out, and the materials will be fully dried during the falling process.
[0027] As an improvement of the above solution, a plurality of reinforcing ribs 33 are provided on the side surface of the guide sleeve 31 along its axial direction.
