Description

一种用于颗粒肥料外包喷涂液体硫磺的装置 技术领域
本发明涉及用于颗粒肥料液体硫磺添加新装置。更具体的说，涉及一种用于颗粒肥料外包喷涂液体硫磺的装置，能对颗粒肥料进行包裹雾化添加。
背景技术
目前国内颗粒肥料生产过程中，不能进行液体硫磺包裹喷涂添加，不能对颗粒肥料进行硫磺中微量添加，所生产的颗粒肥料不能对土壤进行改良。
发明内容
本发明的目的是克服现有技术的不足，提供一种用于颗粒肥料外包喷涂液体硫磺的装置，能够对物料进行精确定量添加的装置。
本发明技术方案描述如下：
一种用于颗粒肥料外包喷涂液体硫磺的装置，包括若干热空气管、若干耐温阀门、若干压力表、若干两相流喷咀、夹套管、液体硫磺管、回流阀，其特征在于：液体硫磺管安装在夹套管内，若干两相流喷咀分别固定在夹套管上，且液体硫磺管与每个两相流喷咀相连，每个两相流喷咀与一根热空气管相连，每根热空气管上安装有一个耐温阀门和一个耐温压力表，在夹套管尾端安装一个回流阀。所述的液体硫磺管和热空气管均为夹套管，液体硫磺管内输送液体硫磺，热空气管输送蒸汽或者导热油。
所述两相流喷咀为喇叭口，且喇叭口与热空气管相连。
所述液体硫磺管为夹套管，夹套内管输送液体硫磺，外管输送蒸汽或者导热油。
本发明的每个喷咀可以单独调节热空气压力，从而使得热空气使液体硫磺能够更好雾化。
本发明热空气通过热空气管进入两相流喷咀，由耐温阀门调节控制热空气压力，与液体硫磺在喷咀末端进行气液混合，得到雾化液硫，由多个喷咀雾化后喷涂到颗粒肥料表面，包裹颗粒肥料。
本发明优点：液体硫磺不凝固；结构紧凑、安装简单、便于操作；可靠性高，使用 寿命长；雾化可调节；多组添加颗粒肥料包裹均匀。
