[0023] 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.
[0024] Reference Figure 1-8 A closed-loop flash drying online granulation intelligent device includes a granulation drying chamber 1, a sieve plate 2 is provided inside the granulation drying chamber 1, a vibration motor 3 is fixed at both ends of the sieve plate 2, a plurality of movable air jet boxes 4 are provided at the bottom of the granulation drying chamber 1, a plurality of atomizing nozzles are evenly distributed on the top of the air jet boxes 4, and an adjustment mechanism is provided inside the granulation drying chamber 1 for adjusting the spacing of the plurality of air jet boxes 4.
[0025] The adjustment mechanism includes a U-shaped mounting plate 6, which is fixed to the top of the granulation drying box 1. A drive motor 7 is bolted to one end of the U-shaped mounting plate 6. A longitudinal threaded rod 11 is fixed to the output end of the drive motor 7. A rectangular moving block 10 is threaded to the outer side of the longitudinal threaded rod 11. A guide plate 5 is provided at one end of the rectangular moving block 10. Multiple U-shaped sliding columns 8 are provided on the outer side of the guide plate 5. A rectangular limiting block 9 is slidably connected to the bottom of the U-shaped sliding column 8. The bottom of the rectangular limiting block 9 is fixedly connected to the granulation drying box 1. The top of the U-shaped sliding column 8 is rotatably connected to the air jet box 4. A rotating mechanism for rotating the air jet box 4 is provided on the outer side of the U-shaped sliding column 8.
[0026] The U-shaped mounting plate 6 also has a longitudinal light rod 12 fixed inside. The longitudinal light rod 12 passes through the interior of the rectangular moving block 10 and is slidably connected to the rectangular moving block 10. By setting the longitudinal light rod 12, the rectangular moving block 10 can move laterally outside the longitudinal light rod 12, thereby enabling the longitudinal light rod 12 to guide the movement trajectory of the rectangular moving block 10. The movement of the rectangular moving block 10 enables the guide plate 5 to move.
[0027] Multiple circular guide rollers 13 are slidably connected inside the guide plate 5. The bottom of the circular guide rollers 13 is rotatably connected to the U-shaped sliding column 8 through a pin, so that the circular guide rollers 13 can slide inside the guide plate 5. The movement of the circular guide rollers 13 allows the U-shaped sliding column 8 to move.
[0028] The guide plate 5 has multiple oblique guide grooves evenly distributed inside, which are adapted to the circular guide roller 13. The circular guide roller 13 is located inside the oblique guide groove and is movably connected to the guide plate 5 through the oblique guide groove. The oblique guide groove allows the circular guide roller 13 to move inside the guide plate 5, thereby allowing the circular guide roller 13 to guide the U-shaped sliding column 8 to move outside the rectangular limiting block 9.
[0029] Here, the operation of the drive motor 7 causes the longitudinal threaded rod 11 to rotate. The rotation of the longitudinal threaded rod 11 causes the rectangular moving block 10 to move longitudinally outside the longitudinal light rod 12. The movement of the rectangular moving block 10 causes the guide plate 5 to move. The movement of the guide plate 5 causes the circular guide roller 13 to drive the U-shaped sliding column 8 to move outside the rectangular limiting block 9, thereby causing the jet box 4 to move and the spacing between the multiple jet boxes 4 to be adjusted.
[0030] The rotating mechanism includes a vertical hydraulic cylinder 14. The vertical hydraulic cylinder 14 is fixed to the outside of the U-shaped sliding column 8. The output end of the vertical hydraulic cylinder 14 is rotatably connected to a horizontal lifting column 15 through a bearing. The outside of the horizontal lifting column 15 is rotatably connected to a vertical transmission column 16. The top of the vertical transmission column 16 is rotatably connected to a rectangular rotating column 17 through a pin. The inside of the top of the rectangular rotating column 17 is fixed to a longitudinal rotating column 18. The longitudinal rotating column 18 and the U-shaped sliding column 8 are rotatably connected through a bearing. The top of the longitudinal rotating column 18 is fixedly connected to the jet box 4.
[0031] A dovetail slider is fixed at one end of the horizontal lifting column 15 near the U-shaped sliding column 8. The U-shaped sliding column 8 has a dovetail groove that matches the dovetail slider. The horizontal lifting column 15 and the U-shaped sliding column 8 are slidably connected by the cooperation of the dovetail slider and the dovetail groove. The dovetail slider and the dovetail groove allow the horizontal lifting column 15 to slide vertically on the outside of the U-shaped sliding column 8.
[0032] Here, the operation of the vertical hydraulic cylinder 14 enables the horizontal lifting column 15 to be raised and lowered vertically. The raising and lowering of the horizontal lifting column 15, through the vertical transmission column 16, enables the rectangular rotating column 17 to drive the longitudinal rotating column 18 to rotate, thereby enabling the air jet box 4 to rotate, so that the air outlet angle of the air jet box 4 can be adjusted, so that the air jet box 4 can dry the material inside the screening plate 2.
[0033] By setting up multiple independent jet boxes 4, the high-temperature gas distribution is more uniform, avoiding the problems of local overheating or insufficient drying caused by traditional single-point drying methods. The multi-angle adjustable design of the jet box 4 allows hot air to impact the material from different directions, significantly improving heat exchange efficiency. The adjustment mechanism can flexibly adjust the spacing of the jet boxes 4 according to the material characteristics, making the material drying more uniform.
[0034] Working principle: The operation of the drive motor 7 enables the longitudinal threaded rod 11 to rotate. The rotation of the longitudinal threaded rod 11 enables the rectangular moving block 10 to move longitudinally outside the longitudinal smooth rod 12. The movement of the rectangular moving block 10 enables the guide plate 5 to move. The movement of the guide plate 5 enables the circular guide roller 13 to drive the U-shaped sliding column 8 to move outside the rectangular limit block 9, thereby enabling the jet box 4 to move and allowing the spacing between multiple jet boxes 4 to be adjusted.
[0035] The operation of the vertical hydraulic cylinder 14 enables the horizontal lifting column 15 to be raised and lowered vertically. The raising and lowering of the horizontal lifting column 15, through the vertical transmission column 16, enables the rectangular rotating column 17 to drive the longitudinal rotating column 18 to rotate, thereby enabling the air jet box 4 to rotate. This allows the air outlet angle of the air jet box 4 to be adjusted so that the air jet box 4 can dry the material inside the screening plate 2.
[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
