Description
Technical Field
[0001] This utility model relates to the field of drying equipment technology, specifically a spiral drying device. Background Technology
[0002] The working principle of a drying device is mainly to utilize the heat energy provided by a heat source, which is transferred to the material through a hot air circulation system. This causes the moisture or other volatile components in the material to evaporate and be discharged from the drying chamber, thereby achieving the purpose of drying. Drying devices are widely used in many fields such as industrial production, food processing, and agriculture. For example, in industrial production, drying devices can be used to dry ores and chemical raw materials; in food processing, drying devices can be used to dry vegetables, fruits, meats, and other foods; and in agriculture, drying devices can be used to dry grains, seeds, and other agricultural products.
[0003] In the current drying equipment, the contact time between the raw material and the drying coil is extremely limited as the raw material falls through the inside of the equipment. This limited contact time directly leads to unsatisfactory drying effect and fails to fully meet the expected drying quality.
[0004] Therefore, a spiral drying device is proposed. Utility Model Content

A connecting toothed ring 45 is fixedly sleeved on the outer side of the drying chamber 41. The front and rear ends of the connecting toothed ring 45 are respectively meshed with the front and rear rotating gears 44.
[0034] A drive motor 46 is fixedly installed on the back of the support frame 3. The output shaft of the drive motor 46 passes through the support frame 3 and the limiting frame 2 in sequence and extends into the interior of the limiting frame 2. The front of the output shaft of the drive motor 46 is fixedly connected to the rear rotating gear 44.
[0035] The drying section includes a fixed base 47, which is fixedly connected to the inner wall of the drying chamber 41. A spiral frame 48 is fixedly sleeved on the outer side of the fixed base 47, and a coil 49 is fixedly installed on the inner wall of the fixed base 47.
[0036] Furthermore, in this embodiment, the raw material is fed into the feed hopper 1, which falls onto the spiral frame 48. The spiral frame 48 in the drying chamber 41 is spirally arranged, so that the raw material slides on the spiral frame 48 during the falling process. The coil 49 in the fixed seat 47 dries the raw material on the spiral frame 48. At the same time, a spiral groove is opened in the drying chamber 41. The drive motor 46 is started, and the drive motor 46 drives the rear rotating gear 44 to rotate. The rear rotating gear 44 drives the connecting gear ring 45 and the drying chamber 41 to rotate. When the drying chamber 41 rotates, it drives the raw material in the drying chamber 41 to rotate.
[0037] Furthermore, in this embodiment, the compact design of the coil 49 and the spiral groove, along with the spiral frame 48, increases the contact time between the raw material and the coil 49 in the drying chamber 41, thereby improving the drying efficiency.

At the same time, the lower placement seat 52 is equipped with an electric heating rod 55, which is located above the conveyor belt 54 and heats the raw material.
[0042] Furthermore, in this embodiment, an electric heating rod 55 is positioned above the conveyor belt 54 to reheat the raw materials that have already undergone preliminary drying, which can ensure that the raw materials are thoroughly dried. The setting of the conveyor belt 54 allows the raw materials to be continuously transported into the collection box 53, avoiding the tediousness and inefficiency of manual operation. At the same time, the design of the collection box 53 also facilitates the storage and subsequent processing of the raw materials.

The spiral frame 48 in the drying chamber 41 is spirally arranged, allowing the raw material to slide on the spiral frame 48 during its descent. The coil 49 in the fixed seat 47 dries the raw material on the spiral frame 48. At the same time, a spiral groove is opened in the drying chamber 41. The drive motor 46 is started, which drives the rear rotating gear 44 to rotate. The rear rotating gear 44 drives the connecting gear ring 45 and the drying chamber 41 to rotate. When the drying chamber 41 rotates, it causes the raw material in the drying chamber 41 to rotate. The dried raw material enters the lower placement seat 52 from the discharge pipe 42. The lower placement seat 52 is equipped with a conveyor belt 54, which transports the raw material falling on the conveyor belt 54 into the collection box 53. At the same time, the lower placement seat 52 is equipped with an electric heating rod 55, which is located above the conveyor belt 54 and heats the raw material.
