The utility model discloses an air cover structure for a paper machine, in which a steam inlet is arranged, an inlet main pipe and an inlet branch pipe are arranged, one end of the inlet main pipe is connected with the steam inlet, the other end of the inlet main pipe is connected with the middle part of the inlet branch pipe, the inlet main pipe is connected with the inlet branch pipe, and the inlet branch pipe is connected with the inlet branch pipe. The connection of the inlet main pipe extends to both sides of the inner wall of the air cover shell. The lower side of the air cover shell forms an arc spray surface. A number of inlet branch pipes are distributed at the inlet branch pipe. The upper end of the inlet branch pipe is connected with the inlet branch pipe, and the lower end of the inlet branch pipe is connected with the spray mouth. It is distributed in a matrix. The steam main pipe enters the inlet branch pipe from the middle, and the whole airway flow is shortened, the length of the pipe is shortened, the space is saved, the heat dissipation pipeline is saved, and the heat efficiency is effectively improved.

一种用于造纸机的气罩结构
本技术涉及造纸机烘干系统的
,尤其是一种用于造纸机的烘干单元气罩结构,特别涉及其机械连接结构。
技术介绍
现有造纸机的烘干单元气罩中,气道沿着气罩壳内壁分布,热量容易透过气罩壳损失,气道过于分散,且气道过长,导致热量损失较大,故仍然需要对现有气罩内腔分布结构进行进一步改进,有效降低能耗。
技术实现思路
本技术的目的在于提供一种用于造纸机的气罩结构,其采用单根进口总管,并且将进口总管设置在气罩壳的中间,有效缩短流程,节省管道,节省空间,避免热量散发损耗,提高热能效率,克服了现有技术中存在的缺点和不足。为了实现上述目的,本技术的技术方案为:一种用于造纸机的气罩结构,包括气罩壳,气罩壳处设有蒸汽进口,气罩壳内设有进口总管和进口支管,进口总管的一端与蒸汽进口连通,进口总管的另一端与进口支管的中段连接,进口总管与进口支管连通,进口支管与进口总管的连接处向两侧延伸至气罩壳的两侧内壁处,气罩壳的下方形成弧形喷射面,进口支管处分布有若干进口分支管,进口分支管的上端与进口支管连接并连通,进口分支管的下端与喷射口连接,喷射口在上述弧形喷射面处呈矩阵状分布, ...
