Description

一种新型蜂巢电场结构 技术领域
本发明涉及静电除油烟领域，尤其涉及的是一种新型蜂巢电场结构。
背景技术
在日常生活或工业生产中，需要对废气进行处理后排放，以达到绿色环保的标准。静电除油烟装置利用电场作用可以有效的除去废气中的油烟，使废气达到排放标准。传统的静电除油烟装置内置有蜂巢电场结构，该蜂巢电场结构由多个除油烟通道排列组成，每一个除油烟通道内安装一根阴极针。工作时，除油烟通道接地，阴极针外接负高压，除油烟通道内部形成强电场，废气通过除油烟通道会被附带上电荷，在强电场的作用下，废气中的油烟分子被吸附在除油烟通道内壁上，达到除油烟的效果。
传统的这种蜂巢电场结构的阴极针一般采用细长钢杆，蜂巢电场结构设置有支架，阴极钢杆一端通过与支架焊接(或螺栓连接)固定在除油烟通道中轴线上(另一端悬空)。一方面，由于钢杆相对较粗，表面光滑，其放电效果较差，除油烟效果不佳，同时钢杆质量大，长时间使用后，悬空的一端容易下坠偏离除油烟通道的中轴线，导致电场分布不均匀，影响除油烟效果；另一方面，钢杆与支架焊接(或螺栓连接)，安装麻烦，耗时费力。
为了提高阴极钢杆的电子释放能力，现有技术中还存在一种阴极钢杆，这种阴极钢杆表面设置有尖刺。一方面，阴极钢杆表面的尖刺数量少、分布散乱，所形成的电弧数量少、分布不均匀；另一方面，这种尖刺一般是通过焊接的方法添加到钢杆表面(或者制作尖刺的部件，安装在钢杆表面)，耗时费力，增加成本。另外，由于在阴极钢杆表面设置尖刺，电场畸变大，对油烟和灰尘的吸附作用大，导致整个阴极钢杆对油烟和灰尘的吸附作用不均匀，尖刺上容易短时间内聚集大量油烟和灰尘，这些油烟和灰尘包裹尖刺，影响静电除油烟装置的除油烟效果，因此需要反复的对其进行清洗，清洗周期短，使用麻烦。
因此，现有技术还有待于改进和发展。
发明内容
本发明的目的在于提供一种新型蜂巢电场结构，旨在解决传统的蜂巢电场结构除油烟效果较差及改善清洗周期频繁的技术问题。
本发明的技术方案如下：一种新型蜂巢电场结构，包括蜂巢结构，所述蜂巢结构包括多个排列设置的除油烟通道，所述每一个除油烟通道中对应设有一根阴极针，其中，所述阴极针为钢丝或钢丝绳；
还包括与阴极针连接并自动调节阴极针松紧度的弹性结构，所述阴极针绷紧设置在除油烟通道的中轴线上。
所述的新型蜂巢电场结构，其中，所述弹性结构为弹簧。
所述的新型蜂巢电场结构，其中，所述弹性结构为弹片。
所述的新型蜂巢电场结构，其中，所述弹性结构与阴极针一体化 制作。
所述的新型蜂巢电场结构，其中，所述阴极针为直径为0.5-1.5毫米的弹簧材质的不锈钢丝，不锈钢丝的一端卷绕形成弹簧结构。
所述的新型蜂巢电场结构，其中，所述蜂巢结构两侧设置有固定弹性结构和阴极针的固定架。
所述的新型蜂巢电场结构，其中，所述固定架平行设置在除油烟通道进气口和出气口的两侧，固定架上设置有多个安装弹性结构与阴极针的装配孔。
所述的新型蜂巢电场结构，其中，所述装配孔中设置有卡位片。
所述的新型蜂巢电场结构，其中，所述钢丝绳两端均设置有绳套。
本发明的有益效果：本发明通过采用钢丝或钢丝绳作为蜂巢电场结构的阴极针，使阴极针更细，电场曲率增大，同时表面粗糙，极大的提高了阴极针的电子释放能力，提高了除油烟质量；另外，钢丝绳上不设置尖刺，使延钢丝绳方向的电场分布一致，对油烟和灰尘的吸附均匀，因此油烟分子和灰尘不会大量集中地被吸附在电场的局部位置上，有效的改善清洗周期短这个问题(传统的阴极针放电不均匀，尖刺上容易快速积聚大量油烟或灰尘，形成灰尘团包裹尖刺，因此需要经常对阴极针进行清洗以保证其除油烟效果)。本发明通过在阴极针的一端设置弹性结构，该弹性结构可以有效的自动调节钢丝或钢丝绳的松紧度，使钢丝绳时刻绷紧地置于除油烟通道的中轴线处，有利于提高电场的均匀性，增强除油烟效果；本发明在固定架上设置有装配孔和卡位片，弹性结构和钢丝绳圈套在装配孔中固定，这种安装方 式简单便利，有利于提高蜂巢电场的组装效率。

具体实施方式
为使本发明的目的、技术方案及优点更加清楚、明确，以下参照附图并举实施例对本发明进一步详细说明。
本发明公开了一种新型蜂巢电场结构，其结构示意图如图1所示，包括蜂巢结构，该蜂巢结构一般有多个排列设置的除油烟通道100组成，每一个除油烟通道100中对应设有一根阴极针。由于传统的阴极针采用钢杆制作，钢杆直径较大，表面光滑，钢杆与除油烟通道100之间形成的电场畸变小，电子释放能力差。本实施例中的这种新型蜂巢电场结构采用钢丝绳替代传统的钢杆作为蜂巢电场的阴极针，如图1中所示，蜂巢结构两侧设置有固定架200，钢丝绳300两端固定连接固定架200，钢丝绳300绷紧设置在除油烟通道100的中轴线上，与除油烟通道100形成电场结构。
如图2所示，为钢丝绳300的结构示意图。从图中可以看出，一方面，钢丝绳300表面粗糙，具有毛刺，在外加高电压时，毛刺放电形成电弧，电子释放能力强，对油烟分子的吸附效果好。另一方面， 钢丝绳半径较小，实际生产中可以采用半径为0.5mm-1.2mm的钢丝绳作为阴极针，阴极针的半径越小，电场畸变越大，释放电子的能力越强，除油烟效果越好。
相同半径下的钢丝绳与钢杆比较，钢丝绳的韧度大，质量轻，并且钢丝绳不易折断，使用寿命长。实际应用中，钢丝绳300可以通过两端拉紧，绷紧设置在除油烟通道100的中轴线上，由于钢丝绳300的质量较小，并且两端固定在除油烟通道100的中轴线上，即使长时间使用，也不会偏离除油烟通道100的中轴线。因此本发明采用钢丝绳300替代钢杆作为蜂巢电场的阴极针，提高电场在油烟通道100的横切面上以阴极针为中心分布的对称性，极大的提高了蜂巢电场的除油烟效果，同时延长了蜂巢电场的使用寿命。
在一个优选的实施方案中，也可以采用钢丝替代钢杆作为蜂巢电场的阴极针设置。
实际生产中，如果单纯的利用固定架200拉紧钢丝绳300，固定架200直接承受钢丝绳300的较大的拉力；在使用时，假如固定架200受碰撞，固定架200容易发生轻微的变形，一旦固定架200发生轻微变形，必定影响钢丝绳300的松紧度，容易导致钢丝绳300无法继续保持绷紧置于除油烟通道100的中轴线上的状态，钢丝绳300变松弛，偏离除油烟通道100的中轴线位置，影响电场在油烟通道100的横切面上以阴极针为中心的分布对称性。本发明为了克服这一缺点，提高蜂巢电场使用的安全性和稳固性，本发明在钢丝绳300的一端设置自动调节钢丝绳300松紧度的弹性结构，该弹性结构一端连接钢丝 绳300，另一端连接固定架200。
本具体实施方式中，选用弹簧作为自动调节钢丝绳300松紧度的弹性结构，但本发明并不对该弹性结构的具体结构进行限定，实际应用中，可以采用弹片等结构作为本发明的弹性结构。
如图4所示，弹簧400两端分别固定连接固定架200和钢丝绳300。弹簧400起缓冲和调节作用，正常工作时，弹簧400为轻微拉伸状态，当固定架受碰撞发生形变，弹簧400也发生相对形变(其形变长度发生改变，弹力也发生改变)，以保证钢丝绳300时刻绷紧的置于除油烟通道100的中轴线上。
在另一个优选的实施方式中，阴极针采用钢丝，弹性结构采用弹簧。但是在实际生产中，为了降低生产成本和提高安装效率，可以采用直径较小的弹簧材质的不锈钢丝(类似钢丝，直径约为0.5-1.5毫米)，作为阴极针，并将该不锈钢丝的未端卷绕形成弹簧形态，制得弹性结构(也就是弹簧与钢丝是一体化制作的)，其结构示意图如图3所示。这种结构巧妙的将弹簧和阴极针结合在一起，不但制作简单，成本低，生产效率高，而且有效地提高了弹簧和阴极针的安装效率(直接省略了弹簧和阴极针连接的工序)。另外，这种结构所达到的除油烟效果也十分出色，使用寿命长，适合推广应用。
为了方便蜂巢电场结构的组装，实际应用中，钢丝绳300两端均设置有绳套310。如图4所示，钢丝绳300通过绳套310与弹簧400圈套连接。
如图1所示，固定架200平行设置在除油烟通道100的进气口和 出气口的两侧，固定架200上设置有多个固定连接弹性结构与钢丝绳300的装配孔210(具体参见图4)。每一个除油烟通道100分别对应有两个装配孔210，这两个装配孔210分别设置在除油烟通道100的两端，弹簧400一端与钢丝绳300的一端分别圈套在对应的装配孔210中(参见图4和图5)。
为了进一步增加钢丝绳300与固定架连接的稳固性，同时提高蜂巢电场的组装效率，如图5所示，在钢丝绳300与装配孔210的连接处，装配孔210中设置有卡位片220。实际组装是，钢丝绳300的绳套310可以直接套在卡位片220上固定。
本具体实施方式中，除油烟通道100设置成圆形通道，钢丝绳300绷紧置于圆形通道的中轴线上。钢丝绳300与圆形通道内壁各处的距离相同，外加高电压后，所形成的电场在油烟通道100的横切面上以阴极针为中心的对称分布。但本发明并不限定除油烟通道100的具体形状，除油烟通道100可以根据实际需要设计成多边形通道、椭圆形通道等。
本发明通过采用钢丝绳300作为蜂巢电场结构的阴极针，由于钢丝绳300半径小，韧性大，同时表面粗糙，在外加高压时，释放电子的能力强，钢丝绳300与除油烟通道100之间形成的电场以钢丝绳为中心对称分布，除油烟效果好，并可延长清洗周期。本发明通过在钢丝绳300的一端设置弹性结构，该弹性结构可以有效的自动调节钢丝绳300的松紧度，使钢丝绳300时刻绷紧的置于除油烟通道100的中轴线处，有利于使电场以钢丝绳为中心对称分布，增强除油烟效果， 延长清洗周期；本发明在固定架200上设置有装配孔210和卡位片220，弹性结构和钢丝绳300圈套在装配孔210中固定，这种安装方式简单便利，有利于提高蜂巢电场的组装效率。
本发明所提供的这种蜂巢电场结构除油烟效果好，使用寿命长，十分适用于日常生活废气处理或工业废气处理。
应当理解的是，本发明的应用不限于上述的举例，对本领域普通技术人员来说，可以根据上述说明加以改进或变换，所有这些改进和变换都应属于本发明所附权利要求的保护范围。
