[0002] In the process of material concentration treatment, scraper concentration pot plays a very key role.The scraper commonly used in the current scraper concentration pot is multiple-piece type non-limiting scraper.This traditional scraper structure exposes many significant defects in practical application.

[0003] Firstly, due to lack of special scraper limiting block, the included angle between scraper and pot body cannot be kept in stable state.In equipment operation, the scraping effect of scraper on material in pot body is greatly discounted, and material is difficult to be thoroughly cleaned, leading to frequent occurrence of material sticking phenomenon on pot wall.With the continuation of production process, these stickies gradually accumulate and are overheated, and finally form paste.Paste production not only reduces the purity and quality of product, so that it cannot reach the expected quality standard, but also seriously hinders the normal concentration process of material, and further greatly influences the yield of product, leading to the great decline of production efficiency.

[0004] Secondly, from the angle of equipment operation cost, the stirrer with this multiple-piece type non-limiting scraper structure has serious problems.The scraper is prone to turn over in running process, and once turning over, the equipment is forced to stop due to failure.In order to restore the normal operation of equipment, workers have to repeatedly adjust process operation, which undoubtedly consumes a lot of manpower, material resources and time cost.Moreover, due to frequent shutdown of equipment and instability of process operation, the continuity and stability of whole extraction operation are destroyed, and the running efficiency is extremely low, so that the energy consumption of whole production process increases, raw material is seriously wasted, thereby leading to high overall operation cost, greatly compressing the profit space of enterprise, and being not conducive to long-term stable development of enterprise in market.
