Description

颗粒捕集装置、颗粒物处理系统和固定结构 技术领域
本实用新型涉及净化和过滤技术领域，具体涉及一种颗粒捕集装置、颗粒物处理系统和固定结构。
背景技术
机动车的尾气中含有大量颗粒物，颗粒物直接排放于空气中会严重污染空气，为了降低车辆尾气中颗粒物的排放，在机动车的发动机后需要安装颗粒捕集装置，它可以在微粒排放物质进入大气之前将其捕捉，以减小污染。
颗粒捕集装置的核心元件是捕集单元。当颗粒捕集装置使用一段时间后，捕集单元中的颗粒物增加，可能会引起排气不畅，对于安装捕集装置的车辆来说会造成加速无力、油耗增加等问题，因此需要将原有的捕集单元拆下更换新的捕集单元，将新的捕集单元与排气单元对接。
现有技术中，捕集单元和排气单元的连接以可靠性为首要考虑的因素，通常采用抱箍与螺栓结合的方式。在拆卸捕集单元之前，需要通过旋拧螺栓以打开抱箍，以将捕集单元与排气单元分离；相应的，在安装捕集单元时，需要将捕集单元与排气单元对准后，旋拧螺栓使抱箍锁紧，进而将捕集单元与排气单元固定。在这种结构中，螺栓的调节需要借助扳手等操作工具。然而，由于捕集单元的安装空间狭小，采用扳手旋拧的过程中，安装空间中的一些组件会对扳手造成干涉，单次旋拧扳手的角度有限，锁紧程度有限，因此，需要耗费较多时间来将螺栓拧紧或调松，操作步骤繁琐。
往往工人的作业条件差，比如温度较高，工人长时间的作业会增加不适感，不利于高效完成作业；另外，在特定的场景下，例如高密集高负荷排队作业环境，低效率的拆装会严重影响其他的作业进度，因此现有的连接方式虽然可靠、稳定，但是在特定场景下并不适用。
发明内容
本实用新型的目的在于提供一种颗粒捕集装置、颗粒物处理系统和固定结构，用以解决现有颗粒捕集装置拆装效率低的问题。
为实现上述目的，本实用新型提供一种颗粒捕集装置，包括排气单元、捕集单元以及将排气单元与捕集单元可拆卸连接的固定组件，固定组件包括：
箍环，其套设在捕集单元与排气单元的连接处，并具有开口；
扣合件，其连接在箍环的开口处且具有使箍环箍紧的扣合状态和使箍环松开的打开状态；以及，
手动操作件，其与扣合件连接以切换扣合件的扣合状态和打开状态。
本实用新型提供的颗粒捕集装置中，固定组件包括箍环、扣合件和手动操作件，手动操作件直接切换扣合件的扣合状态和打开状态，不需要借助操作工具，通过人工操作即可实现捕集单元的拆装。
在安装或拆卸捕集单元的过程中，作业人员的双手可以灵活适应于狭小的作业空间，而且，直接手动施力于手动操作件使扣合件的扣合或打开一步到位，降低了作业难度；与传统的旋拧螺栓的固定方式相比，操作步骤简单，大大缩短了拆装时间，因此，通过采用本实用新型提供的固定组件连接，能够有效提高捕集单元的拆装效率，而且拆装效率不会因安装空间和安装条件等而受到影响，在高负荷、高密度的作业环境下能够推广使用。
在颗粒捕集装置的优选的实现方式中，扣合件包括分别固定在箍环两端的搭接件和定位件，搭接件包括基座、可转动地连接于基座的手柄以及与手柄枢转连接的锁合件，基座固定于箍环，手柄能够转动以使锁合件与定位件扣合或脱离。
扣合件采用搭接件和定位件的设计结构简单，操作灵活。人工施力于手柄驱动其转动，手柄的转动直接控制锁合件与定位件的扣合、脱离，进一步实现捕集单元与排气单元的固定和脱离，从而方便拆卸更换。手柄的设置为人为控制及调节提供了基础，人工借助手动操作间施力于手柄，则能够实现捕集单元 的拆装。
在颗粒捕集装置的优选的实现方式中，搭接件还包括将手柄与基座固定的自锁结构。
通过设置自锁结构，能够使手柄长久的保持在锁合件与定位件扣合的位置，保障捕集单元与排气单元的稳定连接，保障颗粒捕集装置的使用可靠性。

为了更清楚的阐释本实用新型的整体构思，下面再结合说明书附图以示例的方式进行详细说明。
需说明，在下面的描述中阐述了很多具体细节以便于充分理解本实用新型，但是，本实用新型还可以采用其他不同于在此描述的其他方式来实施，因此，本实用新型的保护范围并不受下面公开的具体实施方式的限制。

本使用新型对排气单元10的结构不做限定，例如，在图2所示的实施方式中，排气单元10包括进气筒体11和出气筒体12，进气筒体11和出气筒体12分别连接在捕集单元20的两端，且分别设有进气口111和出气口121，从进气口111进入的气体经由捕集单元20过滤后从出气口121排出。
本实施方式提供的颗粒捕集装置中，固定组件30包括箍环31、扣合件32和手动操作件33，手动操作件33直接切换扣合件32的扣合状态和打开状态，不需要借助操作工具，通过人工操作即可实现捕集单元20的拆装。
在安装或拆卸捕集单元20的过程中，作业人员的双手可以灵活适应于狭小的作业空间，而且，直接手动驱动手动操作件33使扣合件32的扣合或打开一步到位，降低了作业难度；与传统的旋拧螺栓的固定方式相比，操作步骤简单，大大缩短了拆装时间，因此，通过采用本实用新型提供的固定组件30连接，能够有效提高捕集单元20的拆装效率，而且拆装效率不会因安装空间和安装条件等而受到影响，在高负荷、高密度的作业环境下能够推广使用。

搭扣组件的具体结构并不对本实用新型的保护范围形成限定。例如，图8中的搭扣组件中，能够移动的搭接部为环圈，与抱箍或柔性板链相固定的固定部为卡钩，事实上，本领域人员能够理解，能够移动的搭接部可以为卡钩，而固定部为卡槽、卡钩、或者通孔都可以，只需要满足搭接部与固定部既能够扣合也能够分离即可。
