[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.
[0026] See also Figures 1 to 6 , The utility model: A disc dryer with a multi-layer drying disc structure, including a tower body 1, the top and bottom of the tower body 1 are respectively provided with a feeder 2 and a discharger 3, the interior of the tower body 1 is provided with small discs 4 and large discs 5 arranged at equal distances, the small discs 4 and the large discs 5 are arranged alternately, the small discs 4 are in the shape of a cone, the large discs 5 are in the shape of a funnel, and a through hole 6 is opened on the large disc 5. The outer sides of the small discs 4 and the large discs 5 are fixedly connected with an annularly distributed connecting rod 7, the end of the connecting rod 7 close to the tower body 1 is fixedly connected to the inner wall of the tower body 1, the top of the tower body 1 is fixedly connected to a motor 8, the output shaft of the motor 8 is fixedly connected to a rotating rod 9, the bottom end of the rotating rod 9 passes through the tower body 1 and is rotatably connected to the inner bottom wall of the tower body 1, the small disc 4 sets It is arranged on the rotating rod 9 and is rotatably connected thereto. The tops of the small disc 4 and the large disc 5 are respectively fixedly connected with a plurality of small baffle rings 10 and a large baffle ring 11. Both the small baffle ring 10 and the large baffle ring 11 are provided with leakage grooves 12, and the leakage grooves 12 are distributed in a stepped manner. The inner side of the small baffle ring 10 is slidably connected with a scraper 13 distributed in an annular manner, and the outer side of the large baffle ring 11 is slidably connected with a scraper 2 14. The tops of the scraper 13 and the scraper 2 14 are both integrally formed with a connection portion fixedly connected to the rotating rod 9. Two heat source pipes 15 are embedded in the tower body 1. Both heat source pipes 15 are connected with equidistantly arranged conduits 16. The small disc 4 and the large disc 5 are both hollow. One end of the two groups of conduits 16 passes through the tower body 1 and is respectively connected to the small disc 4 and the large disc 5.
[0027] In the present invention, when drying the material, the heat source is first added to the heat source tube 15 on the left, and the heat source enters the multiple small discs 4 and the large disc 5 through the conduit 16. Then the heat source heats the large disc 4 and the small disc 5. Then the heat source is discharged from the conduit 16 into the heat source tube 15 on the right and discharged, thereby achieving the effect of heating the small disc 4 and the large disc 5.
[0028] After the large disc 5 and the small disc 4 are heated to a suitable temperature, the user can transport the material to the top of the small disc 4 at the top through the feeder 2. The material will first fall on the inner side of the small baffle ring 10 with the smallest diameter, and the material will be distributed between the two adjacent scrapers 13. At this time, turning on the motor 8 will drive the rotating rod 9 to rotate clockwise. After the rotating rod 9 rotates, it will drive the scraper 13 and the scraper 2 14 to rotate through the connecting part. At this time, the two adjacent scrapers 13 will drive the material to roll along the top of the small disc 4. After the material rolls along the top of the small disc 4 for nearly a circle, the material will pass through the leakage groove 12 on the small disc 4. Since the small disc 4 is The material has a tendency to move toward the edge of the small disc 4, and the material will be discharged from the leakage groove 12 into the second small baffle ring 10. Then the material will be driven by the two adjacent scrapers 13 on the inside of the small baffle ring 10 to roll along the top of the small disc 4 again until the material rotates nearly one circle. The material will be discharged from the leakage groove 12 on the small baffle ring 10 into the outermost small baffle ring 10. Similarly, the material will be discharged from the leakage groove 12 after rotating nearly one circle in the outermost small baffle ring 10. The material will be located at the top edge of the small disc 4, and the material will roll down from the edge of the small disc 4 and fall onto the top of the large disc 5, thereby completing the primary drying of the material.
[0029] After the material rolls down to the top of the large disc 5, it will first gather on the outside of the large baffle ring 11. The scraper 2 14 on the outside of the large baffle ring 11 will push the material to slide on the top of the large disc 5 until the material passes through the leakage groove 12 on the large baffle ring 11. Since the large baffle ring 11 is funnel-shaped, the material has a tendency to move toward the center of the large baffle ring 11. Therefore, when the material moves to one side of the leakage groove 12, the material will move from the leakage groove 12 to the outside of the next large baffle ring 11. Similarly, as the scraper 2 14 moves, the scraper 2 14 will drive the material to roll along the top of the large disc 5 for nearly one circle. The material will roll from the leakage groove 12 to the outside of the next large baffle ring 11 until it rolls out of the leakage groove 12 on the large baffle ring 11 on the side closest to the rotating rod 9. The material will fall from the through hole 6 on the large disc 5 to the top of the small disc 4 at its bottom, thereby completing the secondary drying process of the material.
[0030] After the material falls onto the top of the next lower disc 4, the material will repeat the drying steps and be dried once more. The material will roll alternately between the small disc 4 and the large disc 5, and then the material will be dried multiple times until the material rolls to the inner bottom wall of the tower body 1. The discharge machine 3 will discharge the material, and finally the drying process of the material will be completed.
[0031] See also Figure 1 , wherein: a controller 17 is fixedly connected to the front of the tower body 1, and an output end of the controller 17 is connected to the motor 8 signal.
[0032] In the present invention, the arrangement of the controller 17 can facilitate the user to control the on and off of the motor 8, thereby improving the practicality of the device.
[0033] See also Figure 3 , wherein: the small retaining ring 10 and the large retaining ring 11 are both embedded with a heating wire 18 , and the controller 17 controls the opening and closing of the heating wire 18 .
[0034] In the present invention, the heating wire 18 can be turned on to heat the small baffle ring 10 and the large baffle ring 11, so that the small baffle ring 10 and the large baffle ring 11 can also have the effect of drying the material, thereby improving the efficiency and effect of the device on drying the material.
[0035] See also Figure 3 , wherein: the inner wall of the tower body 1 is fixedly connected with leak-proof covers 19 arranged at equal distances, the leak-proof covers 19 are shaped like a trumpet, and the bottom of the leak-proof covers 19 is fixedly connected to the large disc 5.
[0036] In the present invention, the provision of the leak-proof cover 19 can collect the materials rolling down from the small disc 4 , thereby preventing the materials from directly falling into the bottom wall of the tower body 1 .
[0037] See also Figure 1 , wherein: a hot air blower 20 is installed on the front of the tower body 1, and the air supply end of the hot air blower 20 is connected to the tower body 1.
[0038] In the present invention, the hot air blower 20 can add hot air to the interior of the tower body 1 to absorb the water vapor escaping from the material during the drying process, prevent moisture condensation on the top of the tower body 1 and in the exhaust pipe, and is equipped with a bag dust collector to capture trace amounts of particularly fine and light materials entrained in the exhaust gas, thereby protecting the environment and reducing product losses.
[0039] The above are only preferred embodiments of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
