It is a new type of improved interior wall painting material, which changes the traditional habit of using cement-based as the gelling material and has excellent compatibility and adhesion with various base walls. During the preparation of gypsum mortar raw materials, it is necessary to dry the raw materials.

[0003] In addition, a drying device for gypsum raw materials is also known from the prior art. The gypsum raw materials are sent into the stirring area through a conveyor belt, the gypsum raw materials are scattered, and then enter the inner cavity of the rotating barrel. The hot air blower blows hot air into the inner cavity of the drying barrel through the air duct, and the hot air dries the gypsum raw materials in the inner cavity of the rotating barrel through the through grooves. However, when the above device is used, the structure and function are single, and the gypsum raw materials are in a piled state in the rotating barrel, resulting in poor drying efficiency of the gypsum raw materials.

An exhaust pipe 13 is arranged at the upper end of the conical cover 12. A drying component is arranged on the drying box 11. A collection box 5 is arranged at the lower end of the drying box 11. A processing component for transferring, diffusing, and separating gypsum mortar raw materials is arranged in the drying box 11;

[0027] In this embodiment: The processing component includes a net cylinder 26 arranged in the drying box 11. One end of the net cylinder 26 is closed. A central shaft 22 runs through the center of the net cylinder 26. A feeding cylinder 21 is arranged on one side of the drying box 11. The feeding cylinder 21 is communicated with the open end of the net cylinder 26. A screw conveyor blade 23 is arranged on the central shaft 22 inside the feeding cylinder 21. A chopping board 24 is arranged on one side of the screw conveyor blade 23. A feeding hopper 4 is arranged at the upper end of the feeding cylinder 21 above the screw conveyor blade 23. One end of the central shaft 22 on one side of the feeding cylinder 21 is connected to a motor 211. The other end of the central shaft 22 is connected to a main pulley 28. A cleaning roller 29 is arranged above the net cylinder 26 inside the drying box 11. One end of the cleaning roller 29 passes through the drying box 11 and is connected to a secondary pulley 210. Screw plates 27 are arranged at intervals on the inner wall of the net cylinder 26. Oblique plates 25 are evenly distributed on the central shaft 22 inside the net cylinder 26. Through holes are arranged on the oblique plates 25. The oblique plates 25 and the screw plates 27 are arranged with a radial gap. A belt is sleeved on the main pulley 28 and the secondary pulley 210.

[0028] The feeding cylinder 21 is welded to the drying box 11. The central shaft 22 is fixedly connected to the net cylinder 26. The net cylinder 26 is rotatably connected to the drying box 11. The screw plates 27 are welded to the net cylinder 26; The central shaft 22 is rotatably connected to the feeding cylinder 21 and the drying box 11. The screw conveyor blade 23 and the chopping board 24 are welded to the central shaft 22. By driving the central shaft 22 to rotate through the motor 211, the screw conveyor blade 23, the chopping board 24, the oblique plates 25, and the net cylinder 26 on the central shaft 22 rotate. The gypsum mortar raw materials in the feeding hopper 4 are pushed towards the chopping board 24 side in the feeding cylinder 21 through the rotation of the screw conveyor blade 23.

[0031] The working principle and usage process of the present utility model: Add the gypsum mortar raw materials into the feeding hopper 4. Drive the central axis 22 to rotate through the motor 211, so that the auger feeding blades 23, chopping plates 24, inclined plates 25 and the mesh cylinder 26 on the central axis 22 rotate. The gypsum mortar raw materials in the feeding cylinder 21 are pushed towards the chopping plate 24 side by the auger feeding blades 23, and are chopped by the chopping plate 24 and then enter the mesh cylinder 26. When the auger plates 27 on the inner wall of the mesh cylinder 26 rotate with the mesh cylinder 26, they lift the gypsum mortar raw materials upwards. The heat generated by the hot air blower 31 dries the lifted gypsum mortar raw materials through the air duct 32. At the same time, when the gypsum mortar raw materials fall, they contact the inclined plate 25, which prolongs the falling time of the gypsum mortar raw materials and improves the drying efficiency. At the same time, the main pulley 28 at the end of the central axis 22 drives the auxiliary pulley 210 at the end of the cleaning roller 29 to rotate, so that the cleaning roller 29 rotates to clean the part of the mesh cylinder 26 that rotates to the uppermost side, avoiding the blockage of the mesh cylinder 26.
