Description

Technical Field

[0001] The utility model relates to the technical field of dryers, and more specifically to a spiral vibration hot air dryer. Background Art

[0002] Dryers can use heat energy to reduce the moisture content in materials. They are common in production activities and are used to improve the efficiency of processing and production of goods.

[0003] Most common dryers are hot air dryers, which dry the materials inside by introducing hot air into the equipment. However, traditional dryers can only perform simple blowing. When drying, the materials inside are mostly piled together, and only the outer materials will fully contact the hot air flow. The materials surrounding the inside are covered by the outer materials and cannot efficiently contact the introduced hot air flow, so that the dryer does not dry the materials uniformly, it is difficult to fully dry the materials, the drying effect is not good, and repeated drying is required, which is time-consuming and laborious; moreover, most existing drying devices heat the outside air, and then pass the high-temperature air into the device to dry the materials. After the air is cooled, the outside air is collected again for heating and passed into the device. This way of providing hot air is relatively wasteful of resources, and it is not easy to ensure the temperature stability inside the equipment, resulting in unstable drying effect; in addition, most common drying equipment has a fixed structure, heavy weight, and is not convenient to move. After the drying of the materials is completed, it is not convenient to empty the internal materials. Workers are required to clear the materials in the equipment little by little, which is labor-intensive and has low work efficiency. Utility Model Content

The gas will flow out of the drying cylinder 2 from the return pipe 13 and flow back to the heating box 3, and then be heated by the heating plate 10, without the need for additional air injection. When the gas flows back to the heating box 3 for heating, it will flow along the channel formed by the first guide plate 28 and the second guide plate 29. The up and down tortuous flow increases the time for the gas to be heated in the heating box 3, so that the heating of the heating plate 10 is more sufficient and the heating effect is improved. In addition, the filter 14 can prevent the material from flowing into the air supply pipe 12 or the return pipe 13, ensuring the stability of gas transmission. At the same time, the drive motor 5 is started to drive the transmission The shaft 4 rotates, and the limit slider 22 cooperates with the limit slot 23, so that the transmission shaft 4 drives the stirring sleeve 6 to rotate, thereby rotating the spiral stirring blade 7 to stir the material in the drying cylinder 2, and when the stirring sleeve 6 rotates with the transmission shaft 4, the guide slot 8 will cooperate with the guide rod 9.

In addition, the guide groove 8 and the guide rod 9 are both located in the matching cavity 24, and are separated from the material space in the drying cylinder 2 by the sealing ring 25. When the stirring sleeve 6 cooperates with the guide rod 9, it will not be affected by the material. Moreover, the guide rod 9 cooperates with the inner wall of the guide groove 8 through the contact ball 27. When the stirring sleeve 6 rotates, the guide groove 8 rotating with the stirring sleeve 6 cooperates with the contact ball 27. The contact ball 27 can automatically rotate under the fixation of the spherical groove 26 to adapt to the changes in the contact surface with the guide groove 8, thereby ensuring smooth cooperation.

The driving cylinder 16 contacts the sliding groove 19 of the support plate 15 through the supporting wheel 18 on the bracket 17, and one end of the support plate 15 is lifted up. The limiting column 20 cooperates with the limiting groove 21 to ensure that the bracket 17 moves stably in the sliding groove 19, so that the supporting wheel 18 and the sliding groove 19 are stably matched. The supporting wheel 18 rotates on the bracket 17 to adapt to the change of the contact point with the support plate 15. Under the force, the connecting end of the support plate 15 and the frame 1 rotates, causing the support plate 15 to tilt, and the support plate 15 drives the drying cylinder 2 to tilt together, and the drying cylinder 2 installed on the support plate 15 has its material port structure end and the rotating end of the support plate 15 at the same end. When the drying cylinder 2 is opened, the material in the drying cylinder 2 will be discharged by itself under the action of gravity. If necessary, the driving motor 5 is started, and the material is loosened by the stirring of the spiral stirring blade 7, which is easier to roll off.
