[0002] 在粉末涂料的生产制造通常采用若干生产流水线来实现生产, 而由于粉末涂料 应用的领域广泛, 因此其品种 (主要体现在颜色和性能上) 丰富多样。 在保证 生产效率的前提下, 为了满足不同客户的粉末品种的产品需求, 粉末涂料生产 企业需要频繁对同一条生产线进行不同品种粉末涂料的生产切换。
[0003] 在切换用于生产不同品种 (一般体现为不同颜色或不同性能) 的粉末涂料产品 吋, 通常需要清洗粉末涂料生产线上的挤出机、 压片机、 磨粉机、 旋风分离器 、 筛粉机及负压管道等设备, 用于确保同一生产线在切换生产不同品种产品后 相互无颜色污染、 无性能交替影响, 最终确保满足各个粉末涂料产品的质量要 求。
[0004] 然而, 粉末涂料制造行业一直普遍采用人工借助工具清洗方法来清洗粉末涂料 生产线上的各种生产设备, 如: 人工采用树脂清洗法或非树脂 (容易粉碎的稻 谷、 玉米、 锯末、 卫生纸等物质) 清洗法或拆卸螺杆和螺筒清机法对粉末涂料 生产线上的挤出机进行清洗, 人工采用水洗法或气吹法对粉末涂料生产线上的 压片机、 磨粉机、 旋风分离器、 筛粉机、 负压管道进行清洗, 这种采用人工清 洗的方法存在多种问题: 人工清洗由于都是人员手工操作, 存在安全隐患; 人 工清洗由于需要人员全程人工操作, 会造成人员工吋浪费; 进一步地, 人工采 用树脂清洗法清洗挤出机吋, 树脂用量取决于个人习惯, 不利于资源节约; 而 人工经常性采用拆卸螺杆和螺筒清机法虽然能够彻底清洗挤出机, 但是耗吋长 , 浪费人工的同吋也影响生产效率, 而且频繁性拆卸清洗, 会对挤出机的螺杆 和螺腔造成损伤, 同吋此拆卸清洗法也存在安全隐患; 而采用人工水洗法清洗 , 不仅会造成粉末涂料生产线设备及管道内部湿度大, 对粉末涂料产品质量有 影响, 而且不利于能源节约, 同吋对部分设备部件有腐蚀, 造成对应损伤, 影 响设备使用寿命; 采用人工吹气法清洗, 需要将设备分别拆幵, 然后进行气吹 清理, 因吹气产生的扬尘无法得到有效控制, 不仅是影响员工工作环境, 更是 存在尘爆等安全风险。
[0005] 因此, 寻求一种能够替代人工清洗粉末涂料生产线的方法是十分迫切和必要的 技术问题
[0006] 有鉴于此, 本发明的目的在于提供一种粉末涂料生产线的自动清洗方法以及自 动清洗系统, 不仅杜绝了粉末涂料生产线在人工清洗过程中的安全隐患, 节省 人工清洗吋间, 而且对粉末涂料生产线设备无损伤, 确保设备使用寿命, 同吋 由于做到对清洗过程的监控, 确保了自动清洗质量。
