[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figures 1-5The utility model provides a rotary vacuum dryer with anti -blocking structure, including rotary vacuum dryer body 1, the top of rotary vacuum dryer body 1 is fixedly arranged with feed pipe 2, and the top of feed pipe 2 is installed with detachable end cap 3, the inside of feed pipe 2 is installed with detachable mounting 6, the middle part of mounting 6 is fixedly arranged with screen assembly 61, and the top of mounting 6 in feed pipe 2 is provided with the fixed ring 5 for clamping mounting 6.

[0021] Wherein, the rotary vacuum dryer body 1 passes through in the closed interlayer and passes into heat energy, such as hot water, low-pressure steam or heat conducting oil, heat is given to the material to be dried through the inner shell, and the tank is slowly rotated under the power driving, the material is handled under the vacuum state, and the steam pressure is lowered to make the moisture on the surface of the material reach the saturation state and evaporate, while being timely discharged and recycled by the vacuum pump, so that the rapid, uniform and efficient drying process is realized. It is worth noting that the specific structure of the rotary vacuum dryer body 1 and its working mode are prior art, so no more will be described.

[0022] Wherein, the outer wall of the fixed ring 5 is provided with external thread 51, the thread cavity 21 is formed in the feed pipe 2 corresponding to the external thread 51, and the diameter of the thread cavity 21 is greater than the diameter of the inner wall of the feed pipe 2.

[0023] Wherein, the thread cavity 21 is formed in the top of the feed pipe 2, and a plurality of buckle grooves 52 are formed in the inner wall of the fixed ring 5. Through the setting of the buckle groove 52, the user can conveniently rotate the fixed ring 5.

[0024] Wherein, the outer wall of the mounting 6 is fixedly provided with a plurality of limiting parts 62, and the inner wall of the feed pipe 2 is correspondingly provided with a plurality of limiting cavities 22. Through the matching of the limiting part 62 and the limiting cavity 22, the stability of the mounting 6 can be further improved.

[0025] Wherein, when the limiting part 62 is clamped in the limiting cavity 22, the fixed ring 5 is fixed on the top of the mounting 6 by screwing.
