Description

机车复合冷却器空气过滤装置 技术领域
本发明涉及一种机车复合冷却器空气过滤装置,属于铁路机车技术领域。
背景技术
在现有机车复合冷却器的通风系统中，车外大气通过离心沉降过滤器和侧墙板式粗滤器进入车顶进气间，再经通风机对机车水散热器和油散热器进行冷却，然后排入大气。离心沉降过滤器和侧墙板式粗滤器的过滤目标针对的是空气和雨水中较大的杂物，经这两者过滤后，仍旧会有很多灰尘等微小物体进入，积留在复合冷却器散的热片上，影响散热。于是在复合冷却器的通风机和油水散热片之间加装网筛式过滤器装置，阻止灰尘积留在冷却器芯子的波纹形散热片上。网筛式过滤装置网孔稀松时，除尘效果不佳；网孔密集时除尘效果较好，但会降低冷却器的通风量，影响散热效果。同时网筛式过滤装置需要定期清洗、更换滤芯，否则滤芯积留灰尘太多也会导致冷却器的通风量、散热效果降低。由于网筛式过滤装置直接固定在复合冷却器内，清洗、更换滤芯时需要对复合冷却器进行拆解，操作难度很大。
发明内容
本发明的目的就是克服上述现有技术之不足，提供一种除尘效果好、清理维护方便的机车复合冷却器空气过滤装置。
本发明的目的是这样实现的：一种机车复合冷却器空气过滤装置，包括壳体与安装在壳体内的静电吸尘滤芯以及集尘盒，所述壳体的进气口与风机的出气口相接，所述壳体的出气口与油水散热器的入气口相接，所述集尘盒为一侧面开门的漏斗式结构，位于静电吸尘滤芯的下游，其特征在于所述静电吸尘滤芯为交叉错位栅格片结构的静电金属板，静电金属板与直流电源相接且与壳体绝缘。
为了更好地实现本发明的目的，所述静电金属板与壳体内风道轴线呈夹角状。
为了更好地实现本发明的目的，所述静电金属板与壳体内风道轴线的夹角a为50°～75°。
为了更好地实现本发明的目的，所述壳体内设有导轨，所述静电金属板可经由壳体侧门沿导轨装入或拆出。
为了更好地实现本发明的目的，所述交叉错位栅格片组之间形成导流槽。
为了更好地实现本发明的目的，所述栅格片呈L状弯曲。
为了更好地实现本发明的目的，所述栅格片断面呈L状。
为了更好地实现本发明的目的，所述栅格片间呈夹角状交叉错位。
为了更好地实现本发明的目的，所述栅格片间交叉错位夹角b为45°～60°。
为了更好地实现本发明的目的，在静电金属板的直流电源开关线路中串接一个与静电金属板卡扣式固定装置机械联动的防触电开关，卡扣式固定装置打开时防触电开关断开并将静电金属板接地放电，卡扣式固定装置闭合时防触电开关接通。
本发明的方案，利用静电将气流中的微小物体吸附到静电金属板，同时由于静电金属板与壳体内风道轴线的夹角及其交叉错位式栅格组结构，使得微小物体在风力和自身重力的双重作用下，顺导流槽沉积到漏斗式沉积盒，有效解决了机车复合冷却器散热片灰尘积留、影响散热的问题。日常只需清理侧面开门的漏斗式集尘盒，在极端情况下也可以通过打开壳体侧门轻易取下抽屉式静电金属板进行清理。大幅度提高了复合冷却器的冷却效果。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
参看图1，本实施例的机车复合冷却器空气过滤装置，壳体2的进气口与通风机1的出气口相接，壳体2的出气口与油水散热器4的入气口相接。壳体2内的静电吸尘滤芯为交叉错位栅格片结构的静电金属板5，它与直流电源相接且与壳体2绝缘。静电金属板5与壳体2内风道轴线呈夹角状，夹角a为50°～75°，可利用风的推力和物体重力对吸附的微小物体进行定向导流。集尘盒7位于静电金属板5的下游，为一侧面开门的漏斗式结构，可有效防止微小物体上扬。
参看图2和图3，交叉错位栅格片组8之间形成导流槽9。参看图4，栅格片10呈L状弯曲，栅格片10间呈夹角状交叉错位，交叉错位夹角b为45°～60°。参看图5，栅格片断面11呈L状。栅格片的L状断面及L状凸起弯曲并错位的设计，可以在保障通风量的前提下，尽可能地增加可吸附面积。同时栅格片10自身所带的角度也便于沉积的小颗粒向导流槽9汇集。
参看图6，壳体2内设有导轨6，采用绝缘材质，通过固定块16固定在壳体2内壁上。静电金属板5可经由壳体2上的静电金属板侧门17沿导轨6装入或拆出。这种导轨式安装结构便于静电金属板5的装卸，方便定期清洗。卡扣式固定装置14用于将静电金属板5固定于导轨6上，并与图7中的防触电开关14.1机械联动。
参看图7，静电金属板5的直流电源开关线路中串接一个与静电金属板卡扣式固定装置14机械联动的防触电开关14.1。在通风机启动按钮15闭合时，静电金属板直流电源接触器12的线圈和通风机工作电路接触器13的线圈同时得电，两个接触器的触点闭合，通风机1开始工作。在直流电源接触器12的触点闭合时，卡扣式固定装置14闭合即防触电开关14.1接通，静电金属板5带静电工作；卡扣式固 定装置14打开即防触电开关14.1断开并接地，静电金属板5静电消除，可以安全取出。
最后应说明的是：以上实施例仅用以说明本发明的技术方案，而非对其限制；尽管参照前述实施例对本发明进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本发明各实施例技术方案的精神和范围。
