The temperature of the flue gas heat exchange tube is directly overhigh, the temperature of the exhausted flue gas exceeds the standard, and the heat loss is extremely large.
Disclosure of Invention
the utility model discloses the technical problem that will solve is: the inner tube type roller dryer can effectively solve the technical problems of lower inner tube arrangement reliability and heat utilization rate of the existing inner tube type roller dryer.
The purpose of the utility model is realized through the following technical measures:
The utility model provides an inner tube formula cylinder drying-machine, includes the barrel, the barrel includes interior barrel and outer barrel, the one end of interior barrel pan feeding mouth is equipped with the flue gas air-supply line, the end of flue gas air-supply line evenly is equipped with the flue gas connecting pipe along the circumference, the end intercommunication of flue gas connecting pipe has the stoving inner tube, the end of stoving inner tube with interior barrel intercommunication, the stoving inner tube passes through the pipeline staple bolt and establishes the surface of interior barrel, be equipped with the exhanst gas outlet on the outer barrel.
Further, the stoving inner tube includes flue gas process pipe and flue gas return pipe, flue gas process pipe with flue gas connecting pipe intercommunication, the end of flue gas process pipe pass through the tip return bend with flue gas return pipe intercommunication, the end of flue gas return pipe pass through half return bend with interior barrel intercommunication.
Furthermore, the smoke process pipe and the smoke return pipe are arranged along the axial direction of the inner cylinder body, and the smoke process pipe and the smoke return pipe are arranged on the inner surface of the inner cylinder body.
Furthermore, the flue gas process pipe and the flue gas return pipe are arranged on the surface of the inner cylinder body through a pipeline hoop.
After the technical scheme is adopted, the beneficial effects of the utility model are that:
The utility model relates to an end of inner tube type drum dryer flue gas air-supply line evenly is equipped with the flue gas connecting pipe along the circumference, and the end intercommunication of flue gas connecting pipe has the stoving inner tube, and the stoving inner tube passes through the pipeline staple bolt and sets up the surface of inner tube body, and hot flue gas gets into the stoving inner tube through the flue gas air-supply line, dries the material, and the material can directly contact with the stoving inner tube, improves heat utilization; the barrel comprises an inner barrel and an outer barrel, the inner barrel is communicated with the drying inner tube, and the outer barrel is provided with a flue gas outlet, so that different thermal expansion stresses of the outer barrel wall caused by temperature changes in the starting and stopping processes are avoided, and the inner barrel and the outer barrel can be heated when flue gas flows between the inner barrel and the outer barrel, and the heat utilization rate is improved; the stoving inner tube passes through the pipeline staple bolt and establishes on the surface of interior barrel, and the stoving in-process material can fully contact with the stoving inner tube, improves drying efficiency.
Because the flue gas process pipe and the flue gas return pipe are axially arranged on the inner surface of the inner cylinder body, the drying efficiency can be effectively improved.
The utility model relates to an inner tube formula cylinder drying-machine simple structure, inner tube range reasonable in design, it is effectual to dry, and the heat utilization efficiency is high.
