Description

Technical Field

[0001] The utility model relates to the technical field of mixing devices, in particular to a mixing and stirring device for silicon nitride and corundum-mullite spraying materials. Background Art

[0002] Corundum has good chemical stability and good corrosion resistance to acids, alkalis and other chemical substances. Mullite can maintain structural stability under rapid temperature changes and reduce cracks caused by thermal expansion. The corundum-mullite spraying material made of corundum and mullite is a refractory material commonly used in high-temperature environments, especially widely used in the linings and protective layers of furnaces, hearths and other high-temperature equipment.

[0003] During the preparation of the corundum-mullite spraying material, silicon nitride needs to be added to the corundum-mullite spraying material. Silicon nitride itself has extremely high hardness and excellent wear resistance. Adding it to the corundum-mullite spraying material can significantly improve the wear resistance of the spraying material. This is of great significance for the long-term use of the spraying material in high-speed airflows and high-temperature environments, and can reduce the surface wear of the spraying material and the wear of particles.

The rotation of the plurality of scraping plates 12 can scrape off the silicon nitride or corundum-mullite spraying materials attached to the inner wall of the mixing tank 2 to make the silicon nitride and corundum-mullite spraying materials fully mixed. After the silicon nitride and corundum-mullite spraying materials are mixed, the control valve 17 can be opened to make the spraying materials discharged through the discharge pipe 4. The connecting shaft 15 drives the auger 14 to rotate to evenly transport the spraying materials. After the spraying materials are emptied, the water pump 6 can be started. The water pump 6 drives the water flow to move through the water delivery pipe 8 towards the nozzle 16 and spray into the mixing tank 2 through the nozzle 16 to clean the mixing tank 2. The water flow can carry impurities and flow through the discharge pipe 4 into the water storage tank 5. The filter plate 23 inside the water storage tank 5 can filter the impurities in the water flow. The filtered water flow can be reused. When the filter plate 23 needs to be cleaned, the electric push rod 7 can be started. The telescopic end of the electric push rod 7 extends to push the brush plate 24 to move on the top side of the filter plate 23. The brush plate 24 pushes the impurities towards the sealing block 25. After pushing the sealing block 25 out of the water storage tank 5, the impurities can be pushed out of the water storage tank 5 to complete the cleaning of the filter plate 23.
