Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Reference Figure 1-4 A drying device for preparing potassium chloride granules includes a box body 1 and a box cover 4 rotatably connected to the upper end thereof. The upper end of the box cover 4 is fixedly connected to a pull ring for facilitating the user to open the box cover 4. The lower end of the box body 1 is fixedly connected to four rectangularly distributed support legs 14 for supporting the box body 1. The lower ends of the support legs 14 are fixedly connected to rubber pads for increasing the friction between the support legs 14 and the ground and enhancing stability. The bottom of the box body 1 is provided with a drainage hole connected to the outside for facilitating the user to drain water from the box body 1.

[0021] In this embodiment, a vertically arranged duct 5 is fixedly inserted at the upper end of the box cover 4 for circulating air. A blower 18 is fixedly embedded in the duct 5 and near the top position for driving the air flow. The air outlet of the blower 18 is set downward. A baffle 17 is fixedly embedded in the duct 5 for preventing debris from entering the blower 18. The baffle 17 is located above the blower 18. A cross-arranged heating tube 19 is fixedly embedded in the duct 5 and near the bottom position for heating the incoming air. A heating wire is fixedly embedded in the heating tube 19 for heating the heating tube 19. A temperature sensor 20 is fixedly connected to the outer wall of the heating tube 19 for detecting the temperature value. The model of the temperature sensor 20 is PT100. A controller 16 is fixedly connected to the upper end of the box cover 4 for cooperating with the temperature sensor 20 to control the start and stop of the heating wire 1. The model of the controller 20 is 80S51. The input end of the controller 16 is electrically connected to the output end of the temperature sensor 20, and the output end of the controller 16 is electrically connected to the input end of the heating wire.

[0022] In this embodiment, a vertically arranged barrel 2 is provided in the box body 1 for driving the material to roll. The lower end of the pipe 5 passes through the box cover 4 and extends into the barrel 2. An opening is provided on the outer wall of the barrel 2, and a filter screen 8 is fixedly embedded in the opening to prevent the material from escaping from the barrel 2. A support ring 3 is rotatably sleeved on the upper end of the barrel 2 for supporting the barrel 2. The outer wall of the support ring 3 is fixedly connected to the inner wall of the box body 1. A servo motor 6 is fixedly embedded on the upper end of the support ring 3 for driving the gear 7 to rotate. The end of the output shaft of the servo motor 6 is fixedly connected to the gear 7 for driving the rack 15 to rotate. A rack 15 meshing with the gear 7 is fixedly connected to the outer wall of the barrel 2 for driving the barrel 2 to rotate. The rack 15 is annularly arranged.

[0023] In this embodiment, the lower end of the barrel 2 is fixedly connected to a support plate 13 for supporting the barrel 2. The lower end of the support plate 13 is rotatably connected to the inner bottom of the box body 1. A hollow groove is provided between the upper end of the support plate 13 and the lower end of the box body 1. A blocking column 11 is slidably inserted in the hollow groove to prevent the material from escaping from the hollow groove. There is a gap of 0.1-0.5 cm between the blocking column 11 and the inner side wall of the hollow groove to prevent the blocking column 11 from affecting the rotation of the barrel 2. The lower end of the blocking column 11 passes through the hollow groove and is fixedly connected to a support plate 12 for supporting the blocking column 11. The upper end of the support plate 12 is fixedly connected to an electric push rod 10 for driving the support plate 12 to rise and fall. The upper end of the electric push rod 10 slides through the box body 1 and is fixedly sleeved with a support block 9 for supporting the electric push rod 10. One end of the support block 9 is fixedly connected to the inner side wall of the box body 1.

[0024] In this embodiment, first, the power of the servo motor 6, the electric push rod 10, the heating wire and the blower 18 is turned on, and then the box cover 4 is opened and unscrewed, and the material is placed in the barrel 2, and then the box cover 4 is closed. When the box cover 4 is closed, the lower end of the pipe 5 is driven to insert into the barrel 2. At this time, the heating wire is started to heat the heating tube 19, and the blower 18 is started to drive the air flow. The air enters the pipe 5 and is heated by the heating tube 19 and then enters the barrel 2. The material is dried by the hot air. At the same time, the servo motor 6 is started to drive the gear 7 to rotate, and the gear 7 drives the rack 15 meshing with it. Rotation, the rack 15 drives the barrel 2 to rotate, and the rotation of the barrel 2 drives the material to roll and move under the action of centrifugal force, so that part of the moisture in the material is dried out, thereby improving the drying efficiency. At the same time, since the material is active, the hot wind and air can contact most parts of the material, thereby improving the drying efficiency. The moisture passes through the filter 8 into the bottom of the box body 1, and the drainage hole is set to facilitate the discharge of the moisture from the box body. Finally, the electric push rod 10 is started to drive the support plate 12 to descend, and the support plate 12 drives the blocking column 11 to detach from the hollow groove, and then the material can be discharged through the hollow groove.

This application only utilizes their functions and does not improve their internal structure. Therefore, they will not be described in detail.

[0026] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
