具体实施方式
以下结合附图和具体实施例对本发明作进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
如图1所示，本发明的汽车涂装过喷漆雾干式捕集***，包括用于承载喷漆室、输送设备、喷涂设备及过喷漆雾干式捕集装置的钢结构骨架1，过喷漆雾沉降室2位于喷漆室下方，为T型结构，过喷漆雾沉降室2上部几乎与喷漆室等宽，喷漆室内产生的过喷漆雾在此区域内沉降并逐渐收拢至下部收窄区。在收窄区内，过喷漆雾被导流至两侧对称布置的过滤单元5内；所述过滤单元设置有可更换的纸盒过滤器53：所述过滤单元设置在滚动装置6上能实现水平移动，所述过滤单元设置有排风口，所述排风口通过排风管路8连接到过滤风箱9。
具体的，作为一个实施例，所述的过滤单元5采用框架和外板51及底座54形成可移动的箱体，纸盒过滤器53安装在箱体内部的纸盒托板52上，纸盒过滤器数量根据工艺布置确定。过喷漆雾从过滤单元的迎风面侧进入纸盒过滤器内，并被纸盒过滤器捕集。净化后的喷漆室排风从过滤单元底座后侧的出风口57排出。
进一步，所述的过滤单元5设置检修门55，用于内部的定期维护，后部设置拉手58，用于拉出旧的过滤单元和推入新的过滤单元。
其中，所述的过滤单元5采用固定夹钳56与前端进风侧所固定安装的风阀4紧密联接，并通过与风阀4框架上安装的密封条41压紧完成密封。风阀执行器42，如电机安装在风阀的框架的顶部，并通过连杆驱动各阀板动作，阀板43采用可拆式结构，受过喷漆雾污染后可拆卸去清洗。
作为一种实施例，所述的滚动装置6可以采用辊排，如采用无动力辊排，正常生产时，过滤单元5放置在无动力辊排上，辊排上间隔布置的滚轮能使过滤单元的拉出或推入更加轻便，从而方便在线或离线维护或更换纸盒过滤器。
进一步，所述的过滤单元的底部出风口57与升降式密封机构7顶部安装的密封条71压紧密封。
其中，所述升降式密封机构包括与出风口配合的密封框74，布置于密封框上端的密封条71，布置于密封框74下端的软连接筒75，所述密封框与承载框的两侧分别设有连杆73，所述的连杆73的上、下端分别与密封框74以及承载框上所安装的能直线移动的直线导轨76为铰接连接，所述承载框与密封框74之间有导向杆77；所述导向杆77布置在密封框另外两个相对侧；当两个所述的直线导轨直线移动时，带动铰接的连杆旋转，会使密封框沿导向杆77实现垂直运动，而软连接筒75则跟从密封框随动，从而能利用与其铰接的连杆73将直 线导轨的直线运动转化密封框74的升降运动。
具体的，所述的升降式密封机构7采用一个气缸72推动直线导轨作直线移动，所述的升降式密封机构7采用所述的软连接筒75与承载框的下端所固定安装的排风管路8密封连接。
本发明中，所述的排风管路8将左右两侧对称布置的过滤单元的排风汇合后，进入过滤风箱9，进行二级过滤处理。排风管8上安装调节风阀81，调节风阀可以结合风量传感器，根据纸盒过滤器的堵塞状态，自动调节阀门开度。
其中，所述的漆雾沉降室2上部设置安全护栏3或安全绳，图示的安全护栏3固定安装在钢结构骨架1顶部横梁上，由栏杆31和钢丝网32两部分组成，钢丝网32可拆卸。
本发明中，所述过滤风箱9内安装袋式过滤器91，可对纸盒过滤器分离吸附后的排风中的少量颗粒物再次净化，实现最终排风颗粒物浓度低于1mg/m3。二级过滤风箱内利用壁板分隔出脏风区92、过滤区93及净风区94。净风区内排风经风机95和风道，可循环至循环风空调，或排至废气处理***。
进一步，所述的过滤风箱顶部设置维修平台96，用于调节风阀81和升降式密封机构7的维修。
作为一个优选的实施例，本发明中，所述的过滤单元5位于平台10之上，与二级过滤的过滤风箱9之间形成两层过滤结构。
进一步，所述过喷漆雾沉降室、过滤单元外侧、与过滤单元进风口连接的风阀、排风管路外侧、过滤风箱各分区内，均布置有符合消防规范的消防喷淋和控制***11，对存在漆雾聚积的设备内外均可实现快速灭火响应。
本发明的(纸盒)过滤单元的更换流程如下：
自动检测纸盒过滤器风压压差，达到更换限值后报警提示更换。经操作人 员确认后，发出更换命令。此时风阀4和调节风阀81关闭，升降式密封机构7的气缸72推杆缩回，带动密封框74下降，密封条71与过滤单元的底部排风口57脱开。以上动作完成后，操作人员手动松开过滤单元前端的固定夹钳56，并将过滤单元5拉出至液压车等转运设备上，再将已安装好新纸盒过滤器的过滤单元5推入更换位置，重新锁紧夹钳，确认更换完成，并由过滤单元到位开关确认后，发出更换完成命令。之后，升降式密封机构7的气缸72推杆伸出，带动密封框74上升，密封条71与过滤单元底部排风口57压紧密封。随后风阀4和调节风阀81自动打开，排风流通，继续捕集过喷漆雾。
以上所有动作机构均有相应传感器检测，且以上更换流程对喷漆室内的正常喷涂生产无影响。更换下来的捕集过喷漆雾达到饱和的过滤单元，则运输至更换站点，在更换点内完成纸盒过滤器的替换。
需要说明的是，本发明以上的实施例中，所涉及的过喷漆雾干式捕集***为过滤单元下出风，设备两层布置的形式。然后其它如过滤单元设置为上出风、过滤单元放置在地面的单层布置、两侧过滤单元对称排风、举升机构采用电机或人工驱动等变形，也均可以实现，均属于本发明的一部分。
进一步的，过滤单元前端的固定夹钳56可升级为电动或气动设备，实现过滤单元前端的自动锁紧密封或解锁。而过滤单元拉出和推入的更换操作及运输也可利用AGV或RGV配合运动抓手实现，从而实现全自动得更换。这也属于本发明的一部分。
以上所述仅是本发明的优选实施方式，应当指出的是，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
