Embodiment 1
[0038] Embodiment 1: A dual-purpose vacuum dryer for steam and heat transfer oil, including a tank body composed of an inner tank 1 and an outer tank 2, an interlayer 4 is formed between the inner tank 1 and the outer tank 2, and the inner tank is equipped with a pump The vacuum device, the tank body includes a barrel body 5 in the middle, a first head 6 and a second head 7 arranged at the end of the barrel body, the first head 6 is provided with a pipe joint 8 communicating with the interlayer 4 .
[0039] A first annular baffle 9 is arranged in the interlayer between the first head 6 and the barrel body 5, and a plurality of first guide plates 10 are arranged between the pipe joint 8 and the first annular baffle 9 to distribute the heat medium evenly. , the first annular baffle 9 is provided with a first guide hole 11 .
[0040]A second annular baffle 12 is provided in the interlayer of the middle part of the barrel body 5, and the second annular baffle 12 is provided with a...
Embodiment 2
[0051] Embodiment 2: The other parts of the present invention are the same as Embodiment 1, the difference is that when the number of the first diversion holes 11 is 2, the 2 first diversion holes 11 are arranged at the position furthest away from the pipe joint 8. On both sides of the symmetry in the distance. The total cross-sectional area of the two first diversion holes 11 is 1-3 times the total cross-sectional area of the four inlet holes. The number of the second diversion holes 13 is two, and the positions of the two second diversion holes 13 correspond to the positions of the first diversion holes 11 . There can be 4 or 6 first guide holes 11 . There can also be 4 or 6 second guide holes 13 .
[0052] The heat medium can be heat transfer oil or steam. When the heat medium is heat-conducting oil, the five heat-transfer zones provided by the invention are heated evenly, absorb heat thoroughly, conduct heat quickly, and have high thermal efficiency, achieving remar...
