The hot water circulation heat exchanger 1c uses a large amount of hot water generated by a waste heat boiler or a steam boiler, and the hot water is conveyed into the hot water circulation heat exchanger 1c through a pipe system to heat air passing through the hot water circulation heat exchanger. The negative pressure fan 1d generates negative pressure through rotation, and continuously generates negative pressure on an air inlet of the hot water circulating heat exchanger 1c during operation, so that an air source continuously enters the drying pipeline 2 after being heated by the hot water circulating heat exchanger 1 c.
As is known, anhydrous sodium sulphate inevitably agglomerates under natural conditions, so that when pipeline transportation is adopted, the anhydrous sodium sulphate is easily blocked at the outlet of the pipeline due to the existence of a rotating shaft support at the outlet of the pipeline, in order to avoid that a bearing at the distal end of the rotating shaft 3d1 is erected at the material inlet 2d to block the anhydrous sodium sulphate from passing through, as shown in fig. 3, the rotating shaft 3d1 penetrates through the material inlet 2d on the drying pipeline which is vertically arranged, the distal end of the rotating shaft 3d1 is erected on the left outer side wall of the straight pipe section 2b, and a bearing 2e is arranged on the left outer wall of the straight pipe section 2b, so that the bearing 2e is not polluted by the anhydrous sodium sulphate and is not easily blocked per; in addition, the design thoroughly solves the problem of obstruction at the anhydrous sodium sulphate inlet, and the anhydrous sodium sulphate is conveyed to the feeding port 2d through the spiral blades without obstruction.
