Acid and alkali corrosion-resistant refractory spray coating for cement kiln preheater
The invention belongs to the technical field of refractory materials, and particularly relates to an acid and alkali corrosion-resistant refractory spray coating for a cement kiln preheater, which isused when the cement kiln preheater is repaired, has the same service life as a castable, but has the advantages of low heat conductivity, low heat loss, favorable acid and alkali atmosphere resistance and lower overall cost than the castable, and has favorable economic benefits and market prospects. On the other hand, a multi-groove-position type stirrer has the advantages that materials can falldown and be fed everywhere on an annular feeding port, and the materials are uniformly dispersed in the feeding process, so that the workload of subsequent rotary stirring is greatly reduced, a multiple material grooves are connected at the same time, switching and discharging are facilitated, the falling materials are convenient to check at any time, and the shaking amplitude of a driving motoris small, and the whole stirrer is safe and efficient to use.
本发明属于耐火材料技术领域，尤其涉及一种水泥窑预热器用抗酸碱腐蚀耐火喷涂料，用于在水泥窑预热器抢修时使用，使用寿命与浇注料相当，但热导率低热损耗少，耐酸碱气氛好，整体成本比浇注料要低，具有较好的经济效益和市场前景。另一方面，多槽位式搅拌机具有环形加料口上处处都能下落加料，加料时就已经有分散均匀的优势了，这样后续旋转搅拌的工作量就大大降低了，而且还具有同时连接多个料槽，方便切换下料，下落的物料方便随时检验查看，以及驱动电机晃动幅度小，搅拌机整体使用安全、高效的优点。
