DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0020] Embodiment: Aluminum fluoride auxiliary drying device, see Figure 1-Figure 5 As shown, it includes a base 1, a mounting ring 2, a drying cylinder 3, a driving motor 4, a gear 5, an outer gear ring 6, a heat pipe 7, a heating rod 8, a spiral blade 9, a scraper 10, a breathable net 11 and a connecting pipe 15. Two mounting rings 2 are arranged on the base 1. A drying cylinder 3 is sleeved between the two mounting rings 2 through a bearing, and the drying cylinder 3 is tilted to be lower on the left and higher on the right, which is beneficial to the continuous automatic conveying and discharging of the aluminum fluoride therein. A connecting pipe 15 is rotatably sleeved on the right end of the drying cylinder 3 for connecting to a feeding pipe for externally conveying aluminum fluoride. Three discharge ports 30 are circumferentially spaced apart on the left side of the drying cylinder 3 for automatically discharging the dried aluminum fluoride. A driving motor 4 is installed on the right side of the base 1. A gear 5 is connected to the output shaft of the driving motor 4 through a coupling. An outer gear ring 6 is sleeved on the right outer wall of the drying cylinder 3, and the gear 5 is meshed with the outer gear ring 6. By starting the driving motor 4, the transmission effect of the gear 5 and the outer gear ring 6 Under the present invention, it can drive the drying cylinder 3 to carry out continuous drying operation and unloading, without pausing unloading in the middle, which is beneficial to saving time cost. A heat conduction pipe 7 is arranged on the left side of the drying cylinder 3, and a heating rod 8 is arranged inside the heat conduction pipe 7. Through the heat conduction effect of the heat conduction pipe 7, the heat generated by the heating rod 8 can be evenly discharged, so that the aluminum fluoride is heated evenly, which is beneficial to drying it. The tube body of the heat conduction pipe 7 is located in the middle of the drying cylinder 3 and the spiral blades 9, which is beneficial to uniformly heating the aluminum fluoride inside the drying cylinder 3. The inner wall of the drying cylinder 3 is provided with spiral blades 9, and scrapers 10 are evenly arranged on the spiral blades 9. The aluminum fluoride can be dispersed during the rotation process, which is beneficial to speed up the drying speed of the aluminum fluoride. At least three air permeable nets 11 are embedded in the side wall of the drying cylinder 3 along the circumferential direction and the axial direction, which are used to quickly discharge the water vapor generated during the drying process of the aluminum fluoride, which is beneficial to maintain the dryness inside the drying cylinder 3.

[0021] The feed pipe filled with aluminum fluoride is connected to the connecting pipe 15, the heating rod 8 is turned on so that the heat pipe 7 can heat the inside of the drying cylinder 3, and the driving motor 4 is started so that the gear 5 can drive the outer gear ring 6 to rotate, thereby driving the drying cylinder 3 and the spiral blades 9 therein to rotate. Since the drying cylinder 3 is inclined with the left side lower and the right side higher, the aluminum fluoride fed from the connecting pipe 15 can be gradually spirally conveyed to the left along the spiral blades 9. In this process, the heat extracted by the heat pipe 7 can dry the aluminum fluoride spirally conveyed in the drying cylinder 3, and the water vapor evaporated during drying can be promptly discharged outside the drying cylinder 3 through the air permeable net 11, and the dried aluminum fluoride will be gradually extracted through the discharge port 30. In this way, continuous automatic flip drying of the aluminum fluoride can be achieved, which is beneficial to improve the efficiency of drying the aluminum fluoride.

[0022] For further information, see Figure 2-Figure 5 As shown, a discharge pipe 12 is also included. Each discharge port 30 is provided with a discharge pipe 12, which is beneficial for guiding the discharge of the dried aluminum fluoride.

[0023] For further information, see Figure 1-Figure 5 As shown, a cover plate 13 is also included. The outer end of each discharge pipe 12 is hingedly connected to the cover plate 13. When the cover plate 13 is closed, the airtightness of the drying cylinder 3 can be increased, which is conducive to maintaining the drying cylinder 3 in a relatively constant temperature state.

[0024] In addition, see Figure 5 As shown, a baffle 14 is also included. A baffle 14 is provided at each of the discharge ports 30 and inside the drying cylinder 3, which is conducive to the smooth discharge of the dried aluminum fluoride and avoids the aluminum fluoride being retained and accumulated at the edge of the discharge port 30 in the drying cylinder 3.

[0025] The blocking effect of the baffle 14 is conducive to guiding the dried aluminum fluoride to the lower material port 30 so that the aluminum fluoride can be discharged more smoothly, and the closing effect of the discharge pipe 12 and the cover plate 13 is conducive to reducing the discharge of heat from the drying cylinder 3, thereby helping the drying cylinder 3 to maintain a relatively constant temperature state, thereby helping to improve the drying efficiency of the aluminum fluoride in the drying cylinder 3.

[0026] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
