[0001] The utility model relates to the technical field of material cleaning of a sintering mixer, in particular to an automatic material cleaning device for a sintering mixer. Background Art

[0002] Sintering mixer is a kind of equipment that needs to work all the time. When mixing stone powder, concentrate, materials, etc., the inner wall of the mixer is seriously sticky due to the addition of water and steam in the high-speed rotating process. It is generally necessary to clean it once every half a month. Some materials are very hard and need to be cleaned with an electric pick. There is a high risk of collapse at any time during the cleaning process. Production cannot be carried out during the cleaning period, which affects normal production and the cleaning cost is high. In addition, the material sticking to the inner wall of the tank makes the mixer body heavy, and the wear of the reducer and the large and small gear rings on the rotating parts is increased, which increases safety hazards. The motor runs overloaded for a long time and requires frequent maintenance. The service life of the internal lining does not reach the normal service life, the accident rate is frequent and the maintenance cost is increased. Frequent shutdowns to replace linings increase maintenance costs, affecting the output of the mixer and the quality of the mixed materials, resulting in increased production costs. At the same time, manual cleaning by workers increases the labor intensity of workers. For this reason, we propose an automatic cleaning device for sintering mixer. Utility Model Content
