Description

Technical Field

[0001] The utility model relates to the technical field of double-cone rotary vacuum drying machines, in particular to a double-cone rotary vacuum drying machine with a conveniently disassembled cover. Background Art

[0002] The double cone rotary vacuum dryer is a double cone rotary tank. When the tank is in a vacuum state, steam or hot water is introduced into the jacket for heating. The heat contacts the wet material through the inner wall of the tank. The water vapor evaporated by the wet material after absorbing heat is pumped away through the vacuum exhaust pipe by the vacuum pump. Since the tank is in a vacuum state and the rotation of the tank makes the material constantly turn up and down, inside and outside, the drying speed of the material is accelerated, the drying efficiency is improved, and the purpose of uniform drying is achieved.

In the prior art, the baffle cover is mostly fixed at the feed inlet of the tank body by bolts. When the baffle cover needs to be removed, multiple bolts need to be removed, which leads to low assembly efficiency of the baffle cover. Utility Model Content
