Description

一种汽车尾气处理装置 技术领域
本发明涉及尾气处理技术领域，尤其涉及一种汽车尾气处理装置。
背景技术
作为空气污染的主要来源之一，汽车尾气中含有大量的有害物质，包括一氧化碳、氮氧化物、碳氢化合物和固体悬浮颗粒等；尾气在直接危害人体健康的同时，还会对人类生活的环境产生深远影响，例如，一、尾气中的二氧化硫具有强烈的刺激气味，达到一定浓度时容易导致“酸雨”的发生，造成土壤和水源酸化，影响农作物和森林的生长；二、汽车排放的尾气中含有大量的可悬浮颗粒，可悬浮颗粒为现有的大气环境中的雾霾的主要来源。
现有技术中已存储诸多汽车尾气处理装置，例如，公开号为CN110559857A的专利文献，其公开了一种环保型汽车尾气处理筒，包括圆柱筒，所述圆柱筒左右设有两组，两组所述相互远离的一侧均固设有管路，所述管路与所述圆柱筒内部连通，左侧的所述管路与进气管路连通，右侧的所述管路与出气管路连通，所述圆柱筒内均开设有内腔，所述内腔的周向外壁上均开设有滑腔，所述滑腔内均滑动设有滑动圆筒，所述滑动圆筒内固设有固定圆盘，该发明可以使尾气进行两次催化，且在转动体的转动下，使尾气加快与曲形催化块和矩形催化块的接触，提高了催化效率。
现有的汽车大多都在排气处安装有尾气处理装置，但是普通的尾气处理装置与汽车底盘安装在一起，并且随着使用时间的增加，装置内会堆积大量的积碳等物质，造成堵塞，影响气体排出的同时降低了处理效果，后期的维护的成本较高，并且安装拆卸极其不便。因此，本申请旨在提供一种能够克服上述缺陷的汽车尾气处理装置。

具体实施方式
下面结合附图对本发明做进一步的描述，本发明的保护范围不局限于以下所述：
如图1至图4所示，本申请提供一种汽车尾气处理装置，至少包括壳体1、第一分隔板2、第二分隔板3、第一吸附组件4和第二吸附组件5。壳体1呈中空状，使得第一分隔板2、第二分隔板3、第一吸附组件4和第二吸附组件5均能够设置于壳体1中。第一分隔板2和第二分隔板3按照彼此大致平行的方式设置于壳体1中，以将壳体1分隔为第一腔体1a、第二腔体1b和第三腔体1c。在第二腔体1b位于第一腔体1a和第三腔体1c之间的情况下，第二腔体1b中设置有连接通道6。第一腔体1a和第三腔体1c经连接通道6彼此连通。第一吸附组件4设置于第一腔体1a中。第二吸附组件5设置于第三腔体1c中。第一腔体1a上设置有进气口7。第二腔体1b上设置有排气口8。在使用时，汽车尾气可以通过进气口7进入第一 腔体1a中，汽车尾气经第一吸附组件4进行处理后由连接通道6进入第三腔体1c，最后经第二吸附组件5再次处理后即可通过排气口8排入大气环境中。
优选的，第一吸附组件4至少包括第一吸附盘4a和第二吸附盘4b，第一吸附盘4a和第二吸附盘4b按照彼此大致平行的方式设置于第一腔体1a中。第一吸附盘4a与进气口7的距离能够小于第二吸附盘4b与进气口7的距离。第一吸附盘4a滑动设置于第一腔体1中以够沿第一腔体1a的轴向移动。第二吸附盘4b固定设置于第一腔体1b中。第一腔体1a上设置有与外界连通的排料通道9。第一吸附组件4至少具有两种工作状态，在第一工作状态下，排料通道9位于第一吸附盘4a和第二吸附盘4b之间，此时排料通道9处于关闭状态，并且排料通道9位于第一吸附盘4a的第一侧，使得汽车尾气能够沿第一腔体14的轴向移动以依次穿过第一吸附盘4a和第二吸附盘4b，从而达到过滤的效果。在第二工作状态下，第一附盘4a朝向第二吸附盘4b移动，使得排料通道9位于第一吸附盘4a的第二侧。例如，如图2所示，第一侧可以是右侧，第二侧可以是左侧，在使用时，第一吸附盘4a能够对汽车尾气进行过滤处理以将其中附带的例如是积碳等颗粒质进行过滤，过滤后的积碳有可能会堆积在第一吸附盘4a的第二侧的腔体中，当第一吸附盘4a由第一工作状态切换为第二工作状态时，第一吸附盘4a第二侧的腔体中堆积的积碳能够通过排料通道9排出，进而达到自动清洁的积碳目的。
优选的，第二体1b中设置有驱动电机10，第一腔体1a中转动设置有螺杆11。驱动电机10连接至螺杆11以为螺杆11的转动提供驱动力，第一吸附盘4a耦合至螺杆11，使得螺杆11沿第一方向转动时，第一吸附盘4a能够朝向第二吸附盘4b移动，或者，在螺杆11沿与第一方向相反的第二方向旋转时，第一吸附盘4a能够背向第二吸附盘4b移动。具体的，第一吸附盘4a至少包括筒体4a-1、支撑立柱4a-2、第一螺纹连接半筒4a-3、第二螺纹连接半筒4a-4、第一压缩弹簧4a-5、电磁铁4a-6和第二压缩弹簧4a-7。若干个支撑立柱4a-2设置于筒体4a-1中，支撑立柱4a-2的延伸方向与筒体4a-1的轴向大致垂直。第一螺纹连接半筒4a-3和第二螺纹连接半筒4a-4上均设置有安装孔，支撑立柱4a-2能够嵌套设置于安装孔中，使得第一螺纹连接半筒4a-3和第二螺纹连接半筒4a-4均能够沿支撑立柱4a-2的延伸方向滑动。第一螺纹连接半筒4a-3和第二螺纹连接半筒4a-4的内壁上均设置有能够与螺杆11啮合的螺纹，进而在螺杆转动时，即可通过螺纹传动的方式实现第一吸附盘4a的移动。第一螺纹连接半筒4a-3通过第一压缩弹簧4a-5连接至筒体4a-1的内壁，第二螺纹连接半筒4a-4通过第二压缩弹簧4a-7连接至筒体4a-1的内壁。在第一螺纹连接半筒4a-3和第二螺纹连接半筒4a-4之间的距离减小的情况下，第一压缩弹簧4a-5和第二压缩弹簧4a-6均能够被拉伸以存储弹性势能，第一螺纹连接半筒4a-3和第二螺纹连接半筒4a-4上均设置有电磁铁4a-6，当电磁铁 4a-6通电工作时，能够产生吸力，进而使得第一螺纹连接半筒4a-3和第二螺纹连接半筒4a-4够相向运动，并且最终彼此完全抵靠接触。当电磁铁4a-6断电时，第一螺纹连接半筒4a-3和第二螺纹连接半筒4a-4在第一压缩弹簧4a-5和第二压缩弹簧4a-7的共同作用下背向运动。
优选的，第一腔体1a中设置有第三压缩弹簧12。筒体4a-1经第三压缩弹簧12连接至壳体1。在筒体4a-1沿螺杆11的延伸方向移动的情况下，第三压缩弹簧12能够被拉伸以储存弹性势能，第一腔体1a中设置有撞击板13。在电磁铁4a-6断电时，第一螺纹连接半筒4a-3和第二螺纹连接半筒4a-4能够背向运动，使螺杆与螺纹能够分离，此时，在第三压缩弹簧12的弹性作用力下，筒体4a-1能够朝向撞击板13移动，并最终与撞击板13抵靠接触，通过撞击板13的阻挡，能够使筒体4a-1静止，此时便能够将第一吸附盘4a上堆积的例如是积碳等物质进行抖落，从而实现第一吸附盘4a的自清洁。
优选的，第一螺纹连接半筒4a-3和第二螺纹连接半筒4a-4上均设置有放置槽14。放置槽14中设置有吸附物15以对汽车尾气进行过滤。吸附物可以是海绵、过滤膜等能够对大颗粒物质进行过滤吸附的组件。
优选的，壳体1上设置有清洗通道16。清洗通道16中可以设置有阀门以能够控制其开启和关闭。连接通道6中也可以设置有阀门以控制其开启和关闭。
本申请的工作原理为：如图2至图4所示，在使用时，进气口7可以与汽车的尾气排放接口连通。清洗通道16可以与吸气泵连通。清洗通道16中可以设置有阀门以控制其开启或关闭。在正常使用时，清洗通道16和排料通道9处于关闭状态，进气口7和连接通道6处于开启状态，并且第一吸附组件4处于第一工作状态，车辆产生的汽车尾气通过进气口7进入第一腔体1a中，汽车尾气在第一腔体1a中从左至右移动，依次穿过第一吸附盘4a和第二吸附盘4b。汽车尾气在通过第一吸附盘4a时，能够被吸附物15进行过滤，使得积碳能够被吸附物15吸附阻挡。汽车尾气在通过第二吸附盘4a时，能够再一次进行过滤。例如，第二吸附盘4a中可以设置有活性炭等吸附物，其能够将汽车尾气中的有害气体进行部分吸收。经第一吸附组件4a处理后的气体经连接通道6进入第三腔体1c中。第二吸附组件5可以是现有技术中常用的三元催化器，其能够与汽车尾气中的有害气体进行化学反应，达到完全消除有害气体的目的。经第二吸附组件处理后的汽车尾气可以通过排气口8排出。
在需要对第一吸附组件4上的积碳进行清洁时，控制电磁铁4a-6通电，电磁铁产生吸附力以使得第一螺纹连接半筒4a-4和第二螺纹连接半筒4a-5相向移动，最终第一螺纹连接半筒4a-4和第二螺纹连接半筒4a-5各自的内壁上的螺纹能够与螺杆11啮合，随后控制驱动电机10工作以带动螺杆11顺时针旋转，此时，第一吸附盘4a能够朝向第二吸附盘4b移动直至排料通道9位于第一吸附盘4a的左侧位置后，控制电磁铁4a-6断电，此时第一螺纹连接半 筒4a-4和第二螺纹连接半筒4a-5将背向移动使得螺纹与螺杆11分离，在第三压缩弹簧12的弹性作用力的作用下，第一吸附盘4a将向左移动并与撞击板13产生碰撞，即可将吸附物15上堆积的积碳抖落，可以多重复几次上述过程，使得第一吸附盘4a多次与撞击板13进行撞击。随后，将第一吸附盘4a向右移动直至排料通道9位于第一吸附盘4a的左侧为止，关闭进气口7和连接通道6，并且开启清洗通道16和排料通道9。最后，开启吸气泵以将外界的空气通过清洗通道16注入第一腔体1a中，进而注入的气体能够带动积碳移动，并最终从排料通道9排出。
最后应说明的是：以上所述仅为本发明的优选实施例而已，并不用于限制本发明，尽管参照前述实施例对本发明进行了详细的说明，对于本领域的技术人员来说，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。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
