[0026] The following is a further description with reference to the accompanying drawings and specific embodiments: Example

[0027] like Figure 1 , Figure 2As shown, a fluidized drying device for calcium carbonate comprises a bin body 1, a guide pipe 11, a hot air blower 2 and a feed bin 4. A sealing plate is detachably provided on the vertical surface of the bin body 1 through bolt connection. The guide pipe 11 is arranged in the bin body 1 and is curved along the height direction of the bin body 1. A feed pipe 12 and an output pipe 13 are provided at the upper and lower ends of the guide pipe 11. Both the feed pipe 12 and the output pipe 13 are arranged through the side wall of the bin body 1 and are inclined along the moving direction of the material. The feed bin 4 is arranged above the feed pipe 12. The end of the output pipe 13 can be sleeved with a rubber tube, which can be directly extended into the storage bag. The hot air blower 2 is arranged on the outside of the bin body 1, and the output end of the hot air blower 2 is connected to the bin body 1. In addition, a one-way valve is provided on the top of the bin body 1. When the device is used to dry calcium carbonate powder, the calcium carbonate powder with high humidity is put into the feed bin 4, and is output from the lower end of the feed bin 4 to the guide pipe 11. Since the guide pipe 11 is bent and inclined, the calcium carbonate powder will move along the direction of the guide pipe 11 and finally be output from the output pipe 13. During the flow of the calcium carbonate powder in the guide pipe 11, the hot air blower 2 works and injects hot gas into the bin body 1. The hot gas contacts the guide pipe 11, and then heats the side wall of the guide pipe 11, increases the temperature inside the guide pipe 11, and then evaporates the water in the calcium carbonate powder to achieve the drying of the calcium carbonate powder. Since the guide pipe 11 is bent and distributed, the time for the calcium carbonate powder to move in the high temperature zone is extended, and the drying of the calcium carbonate powder can be fully achieved. When the air pressure in the bin body 1 exceeds the limit of the one-way valve, the one-way valve opens and discharges the gas. When the air pressure in the bin body 1 is lower than the limit, the hot gas gathers in the bin body 1, which can effectively maintain the temperature of the bin body 1 and the guide pipe 11. This arrangement can avoid the waste of calcium carbonate powder due to gas circulation while achieving sufficient drying of the calcium carbonate powder.

[0028] like Figure 1 , Figure 5 , Figure 6 , Figure 7 , Figure 8As shown, in order to prevent calcium carbonate powder from clogging the guide tube 11, a vibration assembly can also be arranged below the warehouse body 1. Specifically, the vibration assembly includes a support plate 3, a base 5 and a vibration mechanism 6. Two support plates 3 are provided, and are respectively arranged at the two ends of the lower side of the warehouse body 1. A limit column 33 and a limit rod 31 are arranged below the support plate 3. A spring 32 is sleeved on the limit rod 31, and a nut is threadedly sleeved on the lower end. A limit hole 51 is arranged on the upper side of the base 5. The lower end of the limit column 33 is inserted into the limit hole 51. The bottom of the limit rod 31 penetrates the base 5. The spring 32 is in a compressed state, and the two ends are in contact with the base 5 and the support plate 3 respectively. Under the cooperation of the limit column 33 and the limit hole 51, the support plate 3 is stably and movably arranged on the base 5. In addition, under the action of the spring 32, a gap can be left between the support plate 3 and the base 5, so as to provide support for the warehouse body 1 to drive the support plate 3 to vibrate under the action of external force. The vibration mechanism 6 includes a coaxial shaft 61, a motor 63 and two cams 62. The two cams 62 are sleeved on the coaxial shaft 61. Both ends of the coaxial shaft 61 are connected to the base 5 through bearings, and the ends are connected to the output shaft of the motor 63. Under the action of the motor 63, the two cams 62 can be controlled to rotate, and the bin body 1 can be controlled to rise and fall regularly, thereby controlling the bin body 1 and the guide tube 11 to vibrate, forcing the calcium carbonate powder to flip and move down in the guide tube 11. The device can also be used for drying other powders. Example

[0029] like Figure 1 , Figure 2As shown, a fluidized drying device for calcium carbonate comprises a bin body 1, a guide pipe 11, a hot air blower 2 and a feed bin 4. A sealing plate is detachably provided on the vertical surface of the bin body 1 through bolt connection. The guide pipe 11 is arranged in the bin body 1 and is curved along the height direction of the bin body 1. A feed pipe 12 and an output pipe 13 are provided at the upper and lower ends of the guide pipe 11. Both the feed pipe 12 and the output pipe 13 are arranged through the side wall of the bin body 1 and are inclined along the moving direction of the material. The feed bin 4 is arranged above the feed pipe 12. The end of the output pipe 13 can be sleeved with a rubber tube, which can be directly extended into the storage bag. The hot air blower 2 is arranged on the outside of the bin body 1, and the output end of the hot air blower 2 is connected to the bin body 1. In addition, a one-way valve is provided on the top of the bin body 1. When the device is used to dry calcium carbonate powder, the calcium carbonate powder with high humidity is put into the feed bin 4, and is output from the lower end of the feed bin 4 to the guide pipe 11. Since the guide pipe 11 is bent and inclined, the calcium carbonate powder will move along the direction of the guide pipe 11 and finally be output from the output pipe 13. During the flow of the calcium carbonate powder in the guide pipe 11, the hot air blower 2 works and injects hot gas into the bin body 1. The hot gas contacts the guide pipe 11, and then heats the side wall of the guide pipe 11, increases the temperature inside the guide pipe 11, and then evaporates the water in the calcium carbonate powder to achieve the drying of the calcium carbonate powder. Since the guide pipe 11 is bent and distributed, the time for the calcium carbonate powder to move in the high temperature zone is extended, and the drying of the calcium carbonate powder can be fully achieved. When the air pressure in the bin body 1 exceeds the limit of the one-way valve, the one-way valve opens and discharges the gas. When the air pressure in the bin body 1 is lower than the limit, the hot gas gathers in the bin body 1, which can effectively maintain the temperature of the bin body 1 and the guide pipe 11. This arrangement can avoid the waste of calcium carbonate powder due to gas circulation while achieving sufficient drying of the calcium carbonate powder.

[0030] like Figure 1 , Figure 5 , Figure 6 , Figure 7 , Figure 8As shown, in order to prevent calcium carbonate powder from clogging the guide tube 11, a vibration assembly can also be arranged below the warehouse body 1. Specifically, the vibration assembly includes a support plate 3, a base 5 and a vibration mechanism 6. Two support plates 3 are provided, and are respectively arranged at the two ends of the lower side of the warehouse body 1. A limit column 33 and a limit rod 31 are arranged below the support plate 3. A spring 32 is sleeved on the limit rod 31, and a nut is threadedly sleeved on the lower end. A limit hole 51 is arranged on the upper side of the base 5. The lower end of the limit column 33 is inserted into the limit hole 51. The bottom of the limit rod 31 penetrates the base 5. The spring 32 is in a compressed state, and the two ends are in contact with the base 5 and the support plate 3 respectively. Under the cooperation of the limit column 33 and the limit hole 51, the support plate 3 is stably and movably arranged on the base 5. In addition, under the action of the spring 32, a gap can be left between the support plate 3 and the base 5, so as to provide support for the warehouse body 1 to drive the support plate 3 to vibrate under the action of external force. The vibration mechanism 6 includes a coaxial shaft 61, a motor 63 and two cams 62. The two cams 62 are sleeved on the coaxial shaft 61. The two ends of the coaxial shaft 61 are connected to the base 5 through bearings, and the ends are connected to the output shaft of the motor 63. Under the action of the motor 63, the two cams 62 can be controlled to rotate, and the regular lifting and lowering of the bin body 1 can be controlled, thereby controlling the vibration of the bin body 1 and the guide tube 11, forcing the calcium carbonate powder to flip and move down in the guide tube 11.

[0031] like Figure 1 , Figure 3 , Figure 4 As shown, in order to facilitate the cleaning of the calcium carbonate powder adhering to the feed bin 4, the bottom of the feed bin 4 is set to a frustum structure, and a plug rod 45 is set on the bottom surface. At the same time, a connecting frame 41 is fixedly set on the side of the feed bin 4, a slot 14 is set on the top surface of the feed pipe 12, and the plug rod 45 is inserted into the slot 14. The lower end of the connecting frame 41 is set to be open, and a buckle column 43 is fixedly set on the inner side wall. A connecting plate 42 is set on the top of the bin body 1, and a buckle groove 44 is set on the connecting plate 42. The top of the connecting plate 42 is connected by bolts and extends into the connecting frame 41, and the buckle column 43 is located in the buckle groove 44. When it is necessary to clean the feed bin 4, the staff rotates the bolts to release the restrictions of the connecting frame 41 and the connecting plate 42, which provides convenience for the staff to remove the feed bin 4 so as to complete the cleaning of the feed bin 4. The plug rod 45 is inserted into the slot 14, so that the feed bin 4 and the feed pipe 12 can be relatively stably connected. The device can also be used for drying other powders.
