[0027] Specifically, the ferrous sulfate monohydrate rotary kiln is a high-temperature drying and calcining equipment, which uses the rotation and heating functions of the rotary kiln to make the material roll forward in the kiln to achieve the drying, calcining and roasting of the material. The thermal insulation structure of the ferrous sulfate monohydrate rotary kiln is a key part to ensure the temperature stability in the kiln, reduce heat loss and protect the kiln structure; the thermal insulation cover 202 of the fixed edges 201 on both sides of the rotary kiln body 100 can be installed on the upper and lower sides through the inner and outer ends of ... The vacuum chamber 205 in 02 forms a three-layer thermal insulation structure at the outer wall of the rotary kiln body 100, thereby improving the thermal insulation effect on the outer wall of the rotary kiln to reduce the internal heat loss. At the same time, the sealing ports 206 and sealing blocks 207 that are sealed between the two sides of the thermal insulation cover 202 and the fixed edge 201, as well as the multiple sets of fastening screws 210 locked between the thermal insulation cover 202 and the fixed edge 201, can also ensure the sealing of the opening edge of the thermal insulation cover 202 to avoid the problem of poor thermal insulation effect at the opening of the thermal insulation cover 202.

[0028] Embodiment 2:
