The gypsum flow guide 321 is hollow inside. The outer wall of the gypsum flow guide 321 is provided with air holes. The outer wall of the gypsum flow guide 321 is respectively provided with an upper outer thread groove 322 and a lower outer thread groove 323. The upper outer thread groove 322 is threadedly connected with an upper mounting ring 324. The lower outer thread groove 323 is threadedly connected with a lower mounting ring 326. The upper mounting ring 324 and the lower mounting ring 326 are fixedly connected with a filter cloth 325. The bottom of the discharge pipe 4 is fixedly installed with a motor 327 through a mounting seat. The output end of the motor 327 is fixedly connected with a rotating shaft 328. The outer wall of the rotating shaft 328 is fixedly connected with a conveying blade 329. The right side of the furnace cover 5 is penetratedly installed with an exhaust pipe 3210. The inside of the gypsum flow guide 321 is fixedly installed with a feeding pipe 3211.

[0040] In this embodiment, the rotating shaft 328 is rotatably connected with the discharge pipe 4 through a bearing. The bottom end of the exhaust pipe 3210 penetrates the gypsum flow guide 321 and is located in the hollow part thereof. Through the cooperation of the gypsum flow guide 321, the upper outer thread groove 322, the lower outer thread groove 323, the upper mounting ring 324, the filter cloth 325, the lower mounting ring 326, the motor 327, the rotating shaft 328, the conveying blade 329, the exhaust pipe 3210, and the feeding pipe 3211, the gypsum in the furnace body 2 can be in a flowing state, so that the gypsum can be heated more uniformly, and the calcination effect of the gypsum can be better.
