What do benefit to more that material leaches pushes away material scraper blade

The utility model relates to a what do benefit to more that material leaches pushes away material scraper blade. The note the scraper blade height is h, and note material height is H, relation below both satisfy, and h= (0.33 0.42 )H. The utility model discloses highly make reasonable research to the height of scraper blade and material are high, make the scraper blade make scraper blade upper portion oil can tend to with the antedisplacement simultaneously of bottom oil at the in -process that pushes away the material, can not produce the upper portion oil and lag behind the lower part oil,be favorable to improving leaching effect like this, the utility model discloses a current scraper blade is compared to the scraper blade increases on the height to some extent, makes to form a closeindependent unit between the scraper blade again, has prevented miscella cluster check phenomenon, improves the solvent and sprays the effect of soaking, and the powder degree to the material has stronger adaptability simultane
