本发明的实施方式
为使本发明的上述目的、特征和优点能够更加明显易懂，下面结合附图对本发明的具体实施方式做详细的说明。在下面的描述中阐述了很多具体细节以便于充分理解本发明。但是本发明能够以很多不同于在此描述的其它方式来实施，本领域技术人员可以在不违背本发明内涵的情况下做类似改进，因此本发明不受下面公开的具体实施例的限制。
在本发明的描述中，需要理解的是，术语“中心”、“纵向”、“横向”、“长度”、“宽度”、“厚度”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“内”、“外”、“顺时针”、“逆时针”、“轴向”、“径向”、“周向”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。
此外，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括至少一个该特征。在本发明的描述中，“多个”的含义是至少两个，例如两个，三个等，除非另有明确具体的限定。
目前锂电极片薄膜（以下简称薄膜）的生产过程中，激光切割会产生大量的粉尘颗粒，薄膜的粉尘颗粒清除对电池的品质有非常重要的影响。微小的粉尘颗粒如1-50微米大小的粉尘颗粒，粘附在薄膜的表面；由于薄膜非常脆，容易被破坏，故一般的除尘技术难以进行清除，故不能采用接触的方式进行清除，也不能采用水洗的方法进行清除；虽然业内也有采取超声波直接作用于薄膜，但这种方式采用的超声波需离薄膜距离在1-2mm，强大的负压会破坏薄膜，也容易造成损坏。
为了解决上述问题，本实施例公开了一种结合超声波和气体除尘的干式除尘器，其结构如图1至图4所示，该除尘器包括集成有吹气及吸气功能的集尘器100、分别与集尘器100的出气口及进气口连通的除尘头200、正对除尘头200的辊轮301以及位于辊轮301内侧的超声波发生装置400，所述辊轮301用于紧贴待除尘薄膜，所述超声波发生装置400用于产生超声波并作用于辊轮301，所述集尘器100通过除尘头200对薄膜进行吹或吸的动作。其中，从图1可知，除尘头200的形状与辊轮301的形状相适应，使得除尘头200对辊轮301呈包裹状，以达到最优的集尘效果。
具体的，本发明的一种结合超声波和气体除尘的干式除尘器，集尘器100内部设置有两台风机，分别提供正压气流和负压，与集尘器100的出气口连通的除尘头200对紧贴于辊轮301上的薄膜施加气流以吹动粉尘颗粒，同时启动辊轮301内侧的超声波发生装置400，超声波可在无外界干扰、无明显能量损耗的情况下作用于辊轮301，使得辊轮301产生振动并直接传递给薄膜，薄膜在振动过程中能引起粉尘颗粒的振动，破坏气流的边界层，从而使得粉尘颗粒与薄膜脱离；随后与集尘器100的进气口连通的除尘头200对紧贴于辊轮301上的薄膜施加负压，将粉尘颗粒吸取至集尘器100内部，通过集尘器100内置的滤芯获取清洁气体，完成集尘。与现有技术相比，本发明能够有效对薄膜除尘的同时，不易对薄膜造成损坏，保证薄膜的完整性。
在本实施例中，超声波发生装置400包括超声波换能器401以及超声波仪器402，超声波仪器402安装在辊轮301内部，如图4所示，超声波仪器402与不锈钢制的辊轮301紧密接触，薄膜紧贴辊轮301移动，这样超声波传播的途径就不会受到界面的影响，能够在能量不受损失的情况下传递至薄膜的粉尘颗粒上，从而引起粉尘颗粒的振动，破坏气流的边界层；超声波换能器401采用环形、半圆形或者圆形压电陶瓷结构，结构更紧凑，效率更高，超声波换能器401的结构如图5所示。
进一步的，所述除尘头200包括与集尘器100的出气口连通的出气流道101、与集尘器100的进气口连通的进气流道102、开设于出气流道101末端的吹风口201以及开设于进气流道102末端的吸尘口202，所述与出气流道101与进气流道102隔绝设置。在本实施例中，集尘器100产生的气流从吹风口201流出，粉尘颗粒则从吸尘口202进入进气流道102并吸取至集尘器100内部。
进一步的，本实施例中的所述出气流道101内还设置有扰流板203，所述吸尘口202处设置有均流管206，扰流板203包括板体204以及均匀设置于板体204的多个通孔205，多个所述通孔205的直径由中间往四周逐渐变大，多个所述通孔205的间距由中间往四周逐渐变小；均流管206包括管体207及设置于管体207的多个开孔208，多个所述开孔208均与管体207的内腔连通；所述开孔208的直径由靠近管体207内腔的一端往另一端逐渐变小。通过上述设置，能保证气流的稳定分布，从而保证除尘的表面一致性。
具体的，本实施例的干式除尘器还包括第一风速传感器209、第一压力传感器210、第一电磁阀211、第二风速传感器212、第二压力传感器213以及第二电磁阀214，所述第一风速传感器209的检测端及第一压力传感器210的检测端均位于出气流道101内，所述第一电磁阀211用于控制出气流道101的开合，所述第二风速传感器212的检测端及第二压力传感器213的检测端均位于进气流道102内，所述第二电磁阀214用于控制进气流道102的开合；另外，本实施例的干式除尘器还包括颗粒检测装置302以及控制系统，所述颗粒检测装置302位于辊轮301的一侧，所述集尘器100、颗粒检测装置302、超声波发生装置400、第一风速传感器209、第一压力传感器210、第一电磁阀211、第二风速传感器212、第二压力传感器213以及第二电磁阀214均与控制系统信号连接。
在本实施例中，对薄膜进行除尘时，还可分别启动第一风速传感器209、第一压力传感器210、第二风速传感器212、第二压力传感器213以及颗粒检测装置302，第一风速传感器209以检测出气流道101当前的气压值，第二风速传感器212以检测进气流道102当前的风速值，上述风速值反馈至控制系统，即可由控制系统分别发送相应的控制指令至第一电磁阀211或第二电磁阀214，以控制出气流道101或进气流道102当前的流量；第一压力传感器210以检测出气流道101当前的气压值，第二压力传感器213以检测进气流道102当前的气压值，即可有控制系统发送相应的控制指令至集尘器100内两台风机的变频器，以控制当前出气流道101或进气流道102当前的气压；颗粒检测装置302可检测出当前粉尘颗粒的大小，反馈至控制系统，由控制系统分别发送控制指令至超声波发生装置400、集尘器100、第一电磁阀211以及第二电磁阀214，使得本实施例的除尘器可智能调节风量的压力和流量、超声波的频率和强度，从而实现针对性的控制，优化能效。在本实施例中，颗粒检测装置302优选为激光检测仪或CCD相机。
最后应当说明的是，以上实施例仅用以说明本发明的技术方案，而非对本发明保护范围的限制，尽管参照较佳实施例对本发明作了详细地说明，本领域的普通技术人员应当理解，可以对本发明的技术方案进行修改或者等同替换，而不脱离本发明技术方案的实质和范围。
