Description

Technical Field

[0001] The utility model relates to the field of feeding equipment, in particular to an automatic feeding structure of a flash drying machine. Background Art

[0002] The existing flash dryer is a new type of continuous drying equipment that integrates drying, crushing and grading. The flash dryer is particularly suitable for drying filter cake, paste and slurry materials. The traditional flash dryer process can only dry relatively loose materials. If the material has a large specific gravity or a large particle crystal form, the stirring paddle in the existing process rotates in the same direction as the hot air, and the shear force applied to the material is not enough to fully disperse such materials, and the continuous drying effect cannot be achieved, which ultimately leads to a decrease in drying capacity and even deposition of materials inside the dryer, and the drying work cannot be completed. Among them, a flash dryer with application number "CN201821404195.6" is provided. The utility model increases the shear capacity of the blade in the agitator by setting a volute air distributor and making the air flow direction in the air distributor opposite to the rotation direction of the agitator, which can ensure that materials with a large specific gravity or a large particle crystal form are fully dispersed, which is beneficial to improving the drying efficiency and the drying capacity of materials with high moisture or viscosity. However, there is still room for improvement in the use of the flash dryer: the feeding port is provided on one side of the drying tower, and there is no automatic feeding equipment outside the feeding port, so that it is necessary to manually feed the feeding port regularly, thereby reducing the processing efficiency and occupying labor costs. Utility Model Content
