Detailed Implementation
[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0018] Reference Figures 1-8 A drying device for chemical powder materials includes a drying cylinder 1. The outer surface of the drying cylinder 1 is provided with a support 2 for supporting the drying cylinder 1. The upper end of the drying cylinder 1 has two inlets 4, one inlet 4 for powder input and the other inlet 4 for ventilation. The lower end of the drying cylinder 1 has an outlet 3. The inner wall of the drying cylinder 1 is provided with a heating layer. A grid plate 15 is fixedly installed on the inner wall of the middle section of the drying cylinder 1. A rotating shaft 11 is rotatably inserted inside the drying cylinder 1. A sieve plate 13 is fixedly connected to the lower end of the rotating shaft 11. A dispersion body composed of multiple inserts 16 is fixedly connected to the upper section of the rotating shaft 11. The sieve plate 13 is located below the grid plate 15, and the inserts 16 are located above the grid plate 15. A rotating mechanism is provided on the upper surface of the drying cylinder 1. The rotating mechanism is used to drive the rotating shaft 11 to rotate. A reciprocating mechanism is also provided on the surface of the drying cylinder 1. The reciprocating mechanism is located on one side of the rotating mechanism and is used to drive the insert plate 16 and the sieve plate 13 to move up and down reciprocally.
[0019] The lower end of the drying cylinder 1 is provided with an output end 14 whose inner surface is inclined towards the center. The outlet 3 is located at the center of the output end 14. Multiple heating shafts 28 are installed on the inner surface of the upper end of the drying cylinder 1. After drying, the powder can be concentrated downwards along the inclined surface of the output end 14, which facilitates the output of the powder. The addition of heating shafts 28 on the inner surface of the upper end of the drying cylinder 1, with the powder input from the top, enhances the drying and heating effect of the upper part of the drying cylinder 1, thereby improving the drying efficiency.
[0020] Multiple inserts 16 are fixedly connected together by a connecting plate, which is fixedly connected to the rotating shaft 11. Both the upper and lower sides of the inserts 16 are provided with inclined surfaces. By setting both the upper and lower sides of the inserts 16 as inclined surfaces, it is easy to insert them into the powder. When the inserts 16 rotate, they can effectively disperse the powder.
[0021] The rotating mechanism includes a first gear 17 and a second gear 18. The second gear 18 is sleeved on the surface of the rotating shaft 11, and the first gear 17 and the second gear 18 mesh with each other. A first motor 8 is fixedly connected to the drying cylinder 1 via a bracket 7. The drive end of the first motor 8 is fixedly connected to the first gear 17, and the second gear 18 rotates synchronously with the rotating shaft 11. The first motor 8 can drive the first gear 17 to rotate through its drive end. The first gear 17 and the second gear 18 mesh with each other, so the second gear 18 can drive the rotating shaft 11 to rotate, thereby rotating the insert 16 and the sieve plate 13 installed on the rotating shaft 11. The rotating insert 16 can disperse the powder, and the rotating sieve plate 13 can screen the powder, further dispersing the powder during the screening process.
[0022] The reciprocating mechanism includes a second rotating ring 9 and a first rotating ring 10 fixedly connected together by multiple inserts 16. A second motor 5 is fixedly installed on the drying cylinder 1. The second motor 5 is fixedly connected to the surface of the second rotating ring 9 away from the first rotating ring 10 through the drive end. Limiting rails 6 are fixedly installed on the surface of the drying cylinder 1 on both sides of the first rotating ring 10. An installation ring 23 is rotatably sleeved on the upper surface of the rotating shaft 11. A sliding shaft 27 is provided on one side of the installation ring 23. A frame 12 is connected vertically between the two limiting rails 6. The sliding shaft 27 is inserted into the frame 12. An adjusting shaft 25 is fixedly connected to the surface of the first rotating ring 10 away from the second rotating ring 9. The adjusting shaft 25 is also slidably installed in the frame 12. The second motor 5 can drive the second rotating ring 9 to rotate through the drive end. The second rotating ring 9 rotates synchronously with the first rotating ring 10. As the first rotating ring 10 rotates, the height position of the frame 12 can be changed. The sliding shaft 27 is also set inside the frame 12. The frame 12 moves up and down as the first rotating ring 10 rotates. The rotating shaft 11 is driven up and down through the sliding shaft 27 and the mounting ring 23, so the insert 16 and the sieve plate 13 can also move up and down.
[0023] A connecting ring 20 is fixedly installed inside the second gear 18. An opening 21 is provided on the rotating shaft 11, and a retaining shaft 22 is provided inside the connecting ring 20, with the retaining shaft 22 installed within the opening 21. When the second gear 18 rotates, due to the restriction of the connecting ring 20, the second gear 18 can drive the rotating shaft 11 to rotate. When the rotating shaft 11 moves up and down, the retaining shaft 22 can move up and down within the range of the opening 21. The connecting ring 20 ensures that the rotating shaft 11 can also move up and down while rotating.
[0024] A rotating groove is formed on the surface of the second gear 18, and an arc-shaped plate 19 is fixedly installed on the surface of the drying cylinder 1, slidingly mounted within the rotating groove. The arc-shaped plate 19 supports the second gear 18 while ensuring its free rotation. A transverse groove is provided inside the frame 12, within which the sliding shaft 27 and adjusting shaft 25 slide. Slider blocks 24 are fixedly installed at both ends of the frame 12, allowing the two ends of the frame 12 to slide up and down within two limiting tracks 6 via the sliders 24. The limiting tracks 6 limit the frame 12, restricting its movement to only vertical.
[0025] The powder material to be dried is fed into the drying cylinder 1 through one of the inlets 4. A heating layer is provided on the inner wall of the drying cylinder 1. After the material is fed into the drying cylinder 1, it will be heated by the heating layer and will fall directly onto the grid plate 15 for separation. The fed material will be temporarily stored in the space above the sieve plate 13. The rotating mechanism and reciprocating mechanism are activated, causing the insert plate 16 and the sieve plate 13 to move up and down and reciprocate, while also rotating around the rotating shaft 11. When the rotating mechanism and reciprocating mechanism are activated, the first motor 8 drives the first gear 17 to rotate through the drive end. The first gear 17 drives the second gear 18. The second gear 18 rotates, and the second gear 18 is engaged with the rotating shaft 11 through the connecting ring 20. The rotating shaft 11 can rotate with the rotation of the second gear 18. At the same time, the second motor 5 can drive the second rotating ring 9 to rotate through the drive end. The second rotating ring 9 drives the first rotating ring 10 to rotate through the fixed shaft 26. As the first rotating ring 10 rotates, the position of the adjusting shaft 25 can be changed. The height position of the adjusting shaft 25 will change during the rotation, thereby changing the height of the frame 12 through the adjusting shaft 25. During the up and down movement of the frame 12, the sliding shaft 27 will move up and down, and then the sliding shaft 27 will pull the rotating shaft 11 up and down through the mounting ring 23.
[0026] When the insert 16 moves up and down, the inclined surfaces on both the upper and lower sides of the insert 16 can effectively cut the clumps of powder apart. The insert 16 also rotates at the same time, and the rotating insert 16 can continue to crush and pulverize the cut powder, which is beneficial to the separation of clumps of powder. As the insert 16 moves continuously, the powder pre-existing above the grid plate 15 can be effectively dispersed. The dispersed powder can be quickly heated and dried under the action of the internal heating layer and the upper heating shaft 28.
[0027] The material that has been initially dispersed and dried will fall through the grid plate 15 onto the sieve plate 13. The sieve plate 13 will also move up and down and rotate with the rotating mechanism and the reciprocating mechanism. As the sieve plate 13 moves, the initially dried powder can be further heated and dried. Finally, the dried powder can pass through the sieve plate 13 and be output downwards through the outlet 3. Due to the separation between the grid plate 15 and the sieve plate 13, the powder fed into the interior is effectively layered and separated. As the drying process proceeds, the dried powder will eventually be output through the lower end, while the upper end can continuously add powder material. The moisture in the drying process can be output through another inlet 4.
[0028] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
