技术领域
本实用新型属于干燥机技术领域，涉及一种封闭式双层滤饼干燥机防尘网清堵装置。
背景技术
干燥机是一种利用热能降低物料水分的机械设备；滤饼干燥机，是一种对压滤机操作形成的滤饼进行连续烘干后续处理的设备，通过加热常压对流空气使滤饼中的湿分汽化逸出，以获得规定湿含量的固体物料；封闭式双层滤饼干燥机，是一种整机使用厢体封闭式、具有双层丝网输送带的滤饼干燥机，封闭的目的是为了防止干燥过程滤饼扬尘危害、异味排放和减少热量损失。
A形防尘网是滤饼干燥机的重要部件，安装在上层丝网传送带的支架上，用于防止滤饼粉尘随热空气和水蒸气上升通过管道进入换热厢的除湿机构（包括循环冷风机、冷凝器、冷水蒸发器、冷水压缩机等）；粉尘堵网是一种难免的自然现象，防尘网设计为A形，是为了扩大对粉尘的过滤面积，延长粉尘堵塞防尘网的周期，相对减少清洗频率，保证热空气和水蒸气畅通。
现有的A形防尘网，存在以下缺陷：无配套的不停机清洗装置，需要定期停机拆开干燥机上厢体防尘护罩的隔热板，才能拆下A形防尘网，人工清洗后装回，人工清洗又脏又累、水洗需要专用场地，气吹又扬尘四起，污染周边工作环境，劳人伤网、停工误产，影响干燥机的生产效率；如清洗不及时，还影响滤饼干化效果。

进一步地，设置的高压空气总管，附加结构特征是，一端具有与高压空气横管外圆相吻的弧面，另一端具有两段平行的螺纹，利于和高压空气源软管连接。
进一步地，设置的高压空气横管，附加结构特征是，两端封闭，上面具有与高压空气总管相吻的进气孔，下面具有均布的与分流连接管相吻的分流孔。
进一步地，设置的分流连接管，附加结构特征是，两端具有分别于高压空气横管分流孔和高压空气分管进气孔相吻的弧面。
