Description

Technical Field

[0001] The utility model relates to the technical field of refractory powder feeding, in particular to a stirring device for quantitative batching of refractory materials. Background Technique

[0002] A kind of inorganic non-metallic material with a refractoriness of not less than 1580 °C. Refractoriness refers to the Celsius temperature at which a refractory cone specimen does not soften and melt down under the action of high temperature without load. However, defining it only by refractoriness can no longer comprehensively describe refractory materials, and 1580 °C is not absolute. It is now defined that any material whose physical and chemical properties allow it to be used in a high-temperature environment is called a refractory material. Refractory materials are widely used in industrial fields such as metallurgy, chemical industry, petroleum, machinery manufacturing, silicate, and power. They are used in the largest amount in the metallurgical industry, accounting for 50% - 60% of the total output. In the production lines of sliding nozzles, seat-through bricks, and ladle casting materials of the company, the batching process is an essential process.

[0003] The existing technology has the following problems:

[0004] After a large number of searches, it is found that the Chinese patent publication number: CN215743244U, a refractory powder automatic batching device, includes a mixing tank. Several storage tanks are welded to the top of the mixing tank. A discharging mechanism is welded to one side of the bottom of the mixing tank. A forward and reverse motor one is installed on the top of the storage tank through bolts. The output end of the forward and reverse motor one is welded with a rotating shaft one. Stirring rods one are welded to the outside of the rotating shaft one. A screw conveyor one is welded to the outside of the rotating shaft one. A conveying pipe is welded to the bottom of the storage tank. A forward and reverse motor two is installed on one end of the mixing tank through bolts. The output end of the forward and reverse motor two is welded with a rotating shaft two. A screw conveyor two is welded to the outside of the rotating shaft two. This batching device of the utility model has the functions of automation and quantitative conveying, liberates productivity, improves work efficiency, stabilizes batching accuracy, improves product quality and market competitiveness, can fully stir different raw materials for configuring refractory powder, and improves the stability of the output of refractory powder.

[0005] However, the above patent still has problems in actual use. More obviously, it is difficult for the stirring rod two to stir the powder in the left and right directions during the stirring process, resulting in an unsatisfactory stirring effect of the powder, and there is a problem of easy residue of refractory materials during the feeding process, thus making the feeding not clean and thorough enough.

[0006] Therefore, we propose a stirring device for quantitative batching of refractory materials to solve the above drawbacks. Utility Model Content

[0025] Please refer to Figures 1-3 , a stirring device for quantitative batching of refractory materials, including a bottom plate 1. The top surface of the bottom plate 1 is hinged with a stirring tank 3 through a rotating hinge 2, and a plurality of storage tanks 4 with the same structure are arranged on the top surface of the stirring tank 3. The bottom surfaces of the plurality of storage tanks 4 are all installed with feeding pipes 5, and electromagnetic valves 6 are installed on the surfaces of the plurality of feeding pipes 5. A stirring motor 7 is fixedly installed on one side surface of the stirring tank 3, and the output end of the stirring motor 7 extends into the stirring tank 3 and is installed with a rotating rod 8.

A sliding rod 11 is slidably connected inside the chute 10, and a cleaning plate 12 is installed at one end of the sliding rod 11, and the surface of the cleaning plate 12 is closely attached to the inner wall of the stirring tank 3. Driving motors 15 are fixedly installed at the four corners of the top surface of the bottom plate 1, and worms 16 are installed at the output ends of the four driving motors 15.

At this time, the protruding parts of the two cams 17 on the right should be away from the pulley 19, and the right end of the mixing box 3 can move downward. Then, when the protruding parts of the two cams 17 on the right are in rolling contact with the pulley 19, the right end of the mixing box 3 can be lifted upward. At this time, the protruding parts of the two cams 17 on the left should be away from the pulley 19, and the left end of the mixing box 3 can move downward. This cycle repeats). On the one hand, it is convenient to assist in mixing when mixing refractory materials, improving the mixing effect and efficiency of refractory materials and reducing the time required to mix refractory materials evenly.

Then, start the synchronous rotation of the four drive motors 15. The four drive motors 15 drive the four worm gears 16 to rotate. The rotation of the four worm gears 16 drives the four worm wheels 18 to rotate. The rotation of the four worm wheels 18 drives the four cams 17 to rotate. When the protruding parts of two of the cams 17 are in rolling contact with the pulley 19, the protruding parts of the other two cams 17 are away from the pulley 19, so that the mixing tank 3 swings left and right under the action of the rotating hinge 2. On the one hand, it is convenient to play an auxiliary mixing effect when mixing and batching refractory materials, improving the mixing effect and efficiency of refractory materials and reducing the time required for uniform mixing of refractory materials.
