[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 This utility model provides a technical solution: a dry coal preparation hot air device, including a housing 1 and a sorting chamber 2. The sorting chamber 2 is fixedly connected to the top of the housing 1. A filter plate 8 is provided at the bottom of the sorting chamber 2 to screen out impurities in the coal blocks inside the sorting chamber 2. An installation frame 11 is rotatably connected inside the sorting chamber 2. Multiple connecting plates 12 are fixedly connected inside the installation frame 11. The installation frame 11 rotates, causing the connecting plates 12 to rotate, turning over the coal blocks inside the sorting chamber 2 to ensure that the moisture in the coal blocks at the bottom can be evaporated. Heating chambers 3 are symmetrically fixedly connected to both sides of the sorting chamber 2. Heating wires 6 are provided inside the heating chambers 3 to heat the gas inside the heating chambers 3. A fan 4 is fixedly connected to the side of the heating chamber 3 away from the sorting chamber 2. One end of the fan 4 extends through one side of the heating chamber 3 into the heating chamber 3. The fan 4 draws outside gas into the heating chamber 3. A filter screen is installed inside the air inlet to prevent dust and impurities from entering the blower 4 and causing damage to the blower 4. A connecting pipe 7 is fixedly connected inside the heating chamber 3. The end of the connecting pipe 7 away from the heating chamber 3 passes through the side of the sorting chamber 2 and extends into the sorting chamber 2, sending the heated gas in the heating chamber 3 into the sorting chamber 2. A connecting column 13 is fixedly connected to one side of the mounting frame 11. The rotation of the connecting column 13 causes the mounting frame 11 to rotate. A gear 14 is fixedly connected to the end of the connecting column 13 away from the mounting frame 11, passing through the side of the sorting chamber 2. The rotation of the gear 14 causes the connecting column 13 to rotate. A sector plate 15 is rotatably connected to one side of the sorting chamber 2. An arc-shaped rack 17 is slidably connected to one end of the sector plate 15. The arc-shaped rack 17 moves along one end of the sector plate 15. One side of the arc-shaped rack 17 meshes with the gear 14. The movement of the arc-shaped rack 17 causes the gear 14 to rotate.

[0024] Furthermore, a motor 20 is fixedly connected to one side of the sorting chamber 2 via a support frame. The output end of the motor 20 is fixedly connected to a second connecting rod 19 through one side of the fixed frame. When the motor 20 is turned on, it rotates with the second connecting rod 19.

[0025] Furthermore, the end of the second connecting rod 19 furthest from the motor 20 is rotatably connected to the first connecting rod 18, and the second connecting rod 19 rotates to move the second connecting rod 18.

[0026] Furthermore, the end of the first connecting rod 18 away from the second connecting rod 19 is rotatably connected to the sector plate 15, and the movement of the second connecting rod 19 causes the sector plate 15 to rotate back and forth.

[0027] Furthermore, limit blocks 16 are fixedly connected to both ends of the sector plate 15, and the sector plate 15 rotates to move the limit blocks 16.

[0028] Furthermore, a guide plate 9 is fixedly connected inside the housing 1 and directly below the filter plate 8, so that the impurities filtered out by the filter plate 8 move in a specified direction.

[0029] Furthermore, an outlet 10 is provided on one side of the box 1, allowing impurities to leave the box 1 more effectively.

[0030] Furthermore, an inlet 5 is provided at the top of the sorting chamber 2, and a baffle 21 is hinged to the side of the sorting chamber 2 away from the motor 20 to facilitate the removal of the processed coal blocks from the sorting chamber 2.

[0031] In operation, heating wire 6 and fan 4 are turned on. Fan 4 draws outside gas into heating chamber 3, and heating wire 6 heats the gas in heating chamber 3. The heated gas enters sorting chamber 2 through connecting pipe 7 to preheat the temperature in sorting chamber 2. When coal blocks enter sorting chamber 2 through inlet 5, motor 20 is turned on. Motor 20 drives the second connecting rod 19 to rotate, which in turn moves the first connecting rod 18. The first connecting rod 18 moves and causes the fan-shaped plate 15 to swing back and forth. When the fan-shaped plate 15 swings back and forth, when the limiting block 16 contacts one end of the arc-shaped rack 17, the limiting block 16 pushes the arc-shaped rack 17. The arc-shaped rack 17 moves and causes the gear 14 to rotate. The gear 14 rotates through the connecting column. The rotating plate 13 rotates the mounting frame 11, which in turn rotates the connecting plate 12 to turn the coal blocks in the sorting chamber 2. This prevents the water vapor evaporated from the coal blocks from accumulating at the bottom, which would result in residual moisture in the bottom coal blocks. When the fan-shaped plate 15 rotates in another direction with the limiting block 16, the limiting block 16 is far from one end of the arc-shaped rack 17. When the limiting block 16 comes into contact with one end of the arc-shaped rack 17, the arc-shaped rack 17 will move under the push of the limiting block 16. Therefore, the arc-shaped rack 17 rotates intermittently with the gear 14 to prevent the coal blocks in the sorting chamber 2 from being broken due to frequent turning. During the turning process, smaller impurities in the coal blocks will enter the box 1 under the filtration of the filter plate 8 and leave the box 1 through the outlet 10 along the guide plate 9.
