Problems solved by technology

[0002] The washing powder processing process requires the use of a dryer, a mechanical device that uses heat to reduce the moisture content of the material. It is used to dry objects. The dryer evaporates the moisture in the material by heating to obtain a solid material with a specified moisture content. The purpose of drying is to meet the needs of material use or further processing. Although it can avoid the large damage to the heat exchange tube due to thermal expansion and contraction, it cannot avoid the fatigue damage of the connection between the non-condensable gas discharge pipe and the heat exchange tube. During the operation of the dryer, the stress of the welding seam with the heat exchange tube necklace is relatively large, which will cause fatigue damage

Abstract

The invention relates to the field of washing powder equipment, in particular to a steam-pipe rotatory dryer. The steam-pipe rotatory dryer comprises an end plate which is connected with a middle circle heat exchange pipe. The lower side face of the middle circle heat exchange pipe is connected with a connecting pipe which is connected with a ring pipe. The ring pipe is connected with an arc-shaped pipe which is connected with an inner circle heat exchange pipe. The inner circle heat exchange pipe is connected with the arc-shaped pipe, and the ring pipe plays a transition role, so that cracks caused by gas expansion are prevented; furthermore, the inner circle heat exchange pipe is gathered through the connecting pipe to be connected to the middle circle heat exchange pipe, and therefore fatigue damage to the connecting part of a non-condensable gas exhaust part and the middle circle heat exchange pipe is avoided, and in the operation process of the dryer, stress of a welding line part connected with the middle circle heat exchange pipe is reduced.

Description

technical field [0001] The invention relates to the field of washing powder equipment, in particular to a steam tube rotary dryer. Background technique [0002] The washing powder processing process requires the use of a dryer, a mechanical device that uses heat to reduce the moisture content of the material. It is used to dry objects. The dryer vaporizes the moisture in the material by heating and overflows to obtain a solid material with a specified moisture content. The purpose of drying is to meet the needs of material use or further processing. Although it can avoid the large damage to the heat exchange tube due to thermal expansion and contraction, it cannot avoid the fatigue damage of the connection between the non-condensable gas discharge pipe and the heat exchange tube. During the operation of the dryer, the stress of the welding seam with the heat exchange tube necklace is relatively large, which will cause fatigue damage. Contents of the invention [0003] The...
