Description

Technical Field

[0001] The utility model relates to the technical field of tube bundle dryers, in particular to a dryer with an ultraviolet sterilization function. Background Art

[0002] The tube bundle dryer is an indirect heating contact dryer. It uses the principles of heat conduction and heat radiation to transfer the heat of steam through the heat exchange tube wall to the material to be dried on the other side. During the drying process, the material is stirred and pushed by the shovel on the tube, moving from the feed end to the discharge end, and finally discharged through the discharge port. At the same time, the vaporized water is discharged through the fan or natural means, thus completing the entire drying process.

[0003] When drying some materials, a tube bundle dryer is often used. During the use of the tube bundle dryer, the materials are mostly directly put into the dryer for drying. Since the materials are often in a relatively exposed environment, they are easily contaminated by microorganisms. If they are not sterilized, the reproduction of microorganisms may cause the materials to deteriorate, mold, and even produce harmful substances, which will affect their subsequent use.

A movable plate 11 is fixed to one end of the rotating rod 10, and a movable rod 12 is internally movably connected to the other end of the movable plate 11. A cleaning plate 13 for cleaning the surface of the ultraviolet lamp 9 is fixed to the other end of the movable rod 12. The cleaning plate 13 is arranged in an arc shape, and its top is in contact with the bottom surface of the ultraviolet lamp 9, so that the effect of subsequent cleaning can be improved. A driving structure 16 for driving the rotating rod 10 to rotate is arranged on the right side of the tube bundle dryer body 1.

[0023] The driving structure 16 includes a motor 161, a first gear 162 and a second gear 163. The motor 161 is fixed to the right side of the tube bundle dryer body 1. The output shaft of the motor 161 is fixed to one side of the first gear 162. The surface of the first gear 162 is meshed with one side of the second gear 163. The left side of the second gear 163 is fixed to the other end of the rotating rod 10.
