Novel compensator for air port air supply device

一种用于风口送风装置的新型补偿器

Abstract

A novel compensator for an air port air supply device comprises a hot air pipe, a corrugated pipe and a lining thermal insulation layer. The hot air pipe is connected with the corrugated pipe. A guide cylinder is arranged in the hot air pipe. A refractory material layer, a middle thermal insulation layer and an outer thermal insulation layer are arranged between an inner ventilation channel of the hot air pipe and the corrugated pipe in sequence, and a spherical surface is arranged at the lower portion of the guide cylinder. The lining thermal insulation layer and the spherical surface at the lower portion of the guide cylinder are attached and fixed. A refractory material strengthening liner plate is arranged between the middle thermal insulation layer and the outer thermal insulation layer and fixed to the side wall of the guide cylinder through the middle thermal insulation layer. The spherical surface serves as a contact face between the guide cylinder and the lining thermal insulation layer, the sphere center of the spherical surface is accurately positioned at the theoretical hinged point of a cardan joint, and it is ensured that refractory materials inside the compensator cannot interfere with one another when air port equipment deformation is offset through the compensator; the number of the thermal insulation layers between the hot air pipe and the sealing face of the corrugated pipe is increased to three, and the thermal insulation performance of the compensator is improved.
一种用于风口送风装置的新型补偿器,包括热风管、波纹管和内衬隔热层;所述热风管与波纹管连接;所述热风管内设有导流筒,热风管内部通风道和波纹管之间依次设有耐火材料层、中间隔热层和外层隔热层,导流筒下部设为球面;所述内衬隔热层与导流筒下部的球面贴合固定;所中间隔热层和外层隔热层之间设有耐材加强衬板;所述耐材加强衬板通过中间隔热层固定在导流筒的侧壁。本实用新型中导流筒与内衬隔热层采用球面作为接触面,且该球面的球心精确定位于“万向节”的理论铰点,确保了补偿器在弥补风口设备变形时其内部耐材不发生干涉;同时将热风管与波纹管的密封面之间的隔热层增加至三层,提高了补偿器的隔热性能。
