Abstract

A rotary-drum type tube bundle drier comprises a rotary drum (19) and a plurality of heat exchange tubes arranged in a hollow cavity of the rotary drum (19) in an axial arrangement manner. The drier is characterized in that the heat exchange tubes are arranged in the inner cavity of the rotary drum (19) through at least two supporting tube sheets (18) which are arranged transversely and fixedly connected with the inner wall of the rotary drum (19); the heat exchange tubes are composed of steam feeding heat exchange tubes (20) and steam exhausting heat exchange tubes (21) arranged at intervals, and one end of the steam feeding heat exchange tube (20) communicates with one end of the steam exhausting heat exchange tube (21) through connecting tubes to form a loop, wherein the steam feeding heat exchange tube (20) and the steam exhausting heat exchange tube (21) are adjacent, and the other ends of the two heat exchange tubes are respectively connected with a steam feeding collecting ring (16) and a steam exhausting collecting ring (17); the steam feeding collecting ring (16) and the steam exhausting collecting ring (17) respectively communicate with a steam feeding cavity (14) and a steam exhausting cavity (13) in a steam collector (15). The rotary-drum tube bundle drier not only reduces production cost and processing difficulty, but also effectively solves the problems of uneven stress when the heat exchange tubes rotate and leakage between the heat exchange tubes and the tube sheets.

Description

technical field [0001] The invention relates to a drying device, in particular to a drum type tube bundle dryer. The drying machine of the present invention can heat, turn over and stir the material outside the tube bundle through the heat exchange of the tube bundle and the rotation of the drum, so that the material can be evenly dried. The invention is especially suitable for drying processing of loose materials, and can be widely used in alcohol factories, meat industry, fertilizer industry, corn deep processing industry and feed industry. Background technique [0002] The tube bundle dryer is a mechanical device that transfers the heat of water vapor to the material to be dried outside the tube wall through the tube wall of the heat exchange tube according to the principle of heat conduction and heat radiation, so as to achieve the purpose of drying the material. The core component of the mechanical equipment is the heat exchange tube bundle. [0003] The structure of ...
