The invention discloses a nozzle structure of a high temperature and high pressure air flow dyeing machine and its control method, the nozzle structure comprises a front cover, inside the nozzle pipe, spray nozzle and the main sleeve, sleeve is connected with the mainstream in the outside of the tube, the two ends are respectively connected a nozzle head is connected with the front cover and the rear nozzle through the sleeve; is connected with the air inlet of the fan, the outer chamber atomization area formed between the sleeve and the inner annular spray head is arranged on the main flow pipe; atomization area outside the room, including the mainstream fixed on the outer wall of the tube, the spray head and the dyeing pipe connecting the outer chamber; the atomization area is equipped with two outlets and in the mainstream in dyeing cloth after the channel. The invention also provides a control method based on the device, according to the type of cloth to be dyed, determine the opening number, jet flow, the air volume of the fan head and the spray head nozzle temperature technics curve structure. The present invention leveling property, not plugging cloth problem.
【技术实现步骤摘要】
本专利技术属于染色机设计领域,特别涉及一种高温高压气流染色机的雾化喷嘴结构 及其控制方法。
技术介绍
雾化气流染布机属于新工艺新技术,82年开始国外已经有类似设备引进我国,国 内采用这种工艺制造设备有几家,目前国内制造这种设备技术还不成熟,技术难度较大,需 要改进技术问题比较多。雾化气流染布机比传统溢流染色机具有浴比小(1公斤布用3公 斤水叫浴比,传统是1 7以上)的显著优点。目前,染色机按照染整的方式主要分为两种,分别是溢流染色机和气流染色机,溢 流染色机存在浴比大、耗电大、用染化料助剂多、工艺时间长等缺点,并且染布质量也存在 固布面的折痕、管差、色牢度、鸡爪纹等问题。而气流染色机采用空气动力学原理,运用压 力式气流喷嘴将染整液体雾化喷射到织物,使染液雾化气流与织物接触并获得循环拖动的 动力,能够较好解决溢流染色机所存在的问题,其染色工艺符合生态环保的经济染色四要 素——7K、能源、助剂、时间的最少消耗,目前已成为染整领域研究的重点,但是其在应用中 也存在一些问题,主要为以下几点(1)气流与染液的流向和流速没有很好的匹配,导致气 流对染液的喷射产生干扰,使得 ...
【技术保护点】
高温高压气流染色机的雾化喷嘴结构,包括前喷嘴盖、内主流管和后喷嘴头,内主流管的前端设置有前导向嘴,其特征在于,还包括套筒,所述套筒套接于内主流管外部,其两端分别通过连接件与前喷嘴盖和后喷嘴头连接;套筒上设置有与风机相连的进风口,套筒与内主流管之间形成环形的外室雾化区;所述喷射头设置在外室雾化区内、固定在内主流管外壁上,所述喷射头与染液管道相连接;所述外室雾化区设有两个出口与内主流管中待染布匹经过的通道相连。
