作为本发明的一种实施方式，如图3所示，所述集尘罩32在远离开口的一端为涡形。
作为本发明的一种实施方式，如图1所示，所述集尘罩32由一对对称的壳体拼合而成，所述壳体之间通过螺钉固连。
工作时，通过将集尘罩32的侧壁设置为弧形，且集尘罩32的开口为窄口，窄口处的开口直径与过滤网21的直径相当，集尘罩32在远离开口处的直径大于过滤网21的直径，在异物杂质等被刮板31刮落到集尘罩32的内壁上时，异物杂质等沿着弧形的侧壁向远离开口的一侧移动，且在进气口的气流吹动下，使得异物杂质等向远离开口的一侧移动，从而使得异物杂质等不易从开口处逸出，集尘罩32在远离开口的一端为涡形，使得此处移动到异物杂质等被束缚，不易扩散，避免造成二次污染，定期对集尘罩32进行清理，将螺钉拧下，将对称的壳体分开，再将壳体中的杂质进行清理，清理完成后再安装到进风口2处，拧紧螺钉，便于收集异物杂质。
作为本发明的一种实施方式，如图4所示，所述集尘罩32远离开口处一侧与所述进 风口2之间连通有细管5，所述细管5将集尘罩32和所述进风口2连通。
作为本发明的一种实施方式，如图4所示，所述细管5靠近所述集尘罩32的一端固连有防尘网51。
工作时，通过设置细管5，使得集尘罩32和进风口2连通，空气在进风口2处流过时，进风口2处的气体流速加快，使得进风口2处的压强减小，使得细管5处产生负压，对异物杂质等进行吸引，进一步控制集尘罩32中异物杂质等移动，且在集尘罩32上安装防尘网51，将异物杂质等限制在集尘罩32中，减少异物杂质等从进风口2进入到风机本体1中，从而避免损坏叶轮，保证漩涡风机正常工作。
作为本发明的一种实施方式，如图1至图3所示，所述进风口2处为喇叭口，所述喇叭口处均匀固连有多个进气支管22，其中一个所述进气支管22为闭合状态，其余所述进气支管22的通风截面积之和大于所述进风口2的通风截面积。
作为本发明的一种实施方式，如图2所示，所述过滤网21由多个扇形块23拼合，所述扇形块23的面积大于所述进气支管22的通风截面积。
工作时，通过将进风口2设置为喇叭口，在喇叭口设置多个进气支管22，进气支管22的通风截面积之和大于进风口2的通风截面积，保证进风口2的进气通畅，由于进风口2处设置有过滤网21，一定程度上会阻碍进气，增大通风截面积，便于进气，防止因进气量不足导致漩涡风机过热，从而使得漩涡风机处于安全工作温度，保证漩涡风机的正常工作，通过将过滤网21分割为多个扇形块23，且扇形块23的面积大于进气支管22的通风截面积，在过滤网21使用一段时间后，开口的进气支管22处的过滤网21需要进行更换时，将需要更换的扇形块23转动到闭合的进气支管22处，再进行更换，不需要停机即可完成对过滤网21完成检修，保证工作时常，从而提高生产效率。
作为本发明的一种实施方式，如图2所示，所述过滤网21为弧面。
作为本发明的一种实施方式，如图2所示，所述刮板31上固连有扇叶33。
工作时，通过将过滤网21设置为弧面，弧面凸起一侧与进气方向相对，在空气中的异物杂质等被过滤网21拦截后，在气流的作用下，顺着过滤网21的弧面滑动到集尘罩32中，使得异物杂质等不易在过滤网21上堆积，且便于清理，在刮板31上固连有扇叶33，在气流的作用下，扇叶33转动，从而带动刮板31转动，从而对过滤网21进行清理，自动清理过滤网21，减轻人员的工作强度，便于使用。
具体工作流程如下：
工作时，通过设置除尘装置3，在漩涡风机工作时，风机本体1包括电机和叶轮，电 机转动驱动叶轮转动，从进风口2处进行抽气，漩涡风机的叶轮由数十片叶片组成，它类似庞大的气轮机的叶轮，叶轮叶片中间的空气受到了离心力的作用，向叶轮的边缘运动，在那里空气进入泵体环行空腔，重新从叶片的起点以同样的方式再进行循环，叶轮旋转所产生的循环气流，以极高的能量离开气泵以供使用，高压气体从出风口4排出，空气中的异物杂质等在进入进风口2处时，异物杂质等被过滤网21截留下来，人员转动刮板31，刮板31从过滤网21的表面刮过，将过滤网21上的杂质清理下来，杂质受到自身重力的影响，杂质落入到集尘罩32中，另一方面杂质经刮板31刮动，刮板31的推力给杂质一定的离心力，使得杂质径向移动落入到集尘罩32中被收集，减少杂质颗粒弥散到空气中，影响工作环境，保证工作人员人生安全，且便于工作人员清理过滤网21，提高人员的工作效率，从而减少停机，进而提高生产效率；通过将集尘罩32的侧壁设置为弧形，且集尘罩32的开口为窄口，在异物杂质等被刮板31刮落到集尘罩32的内壁上时，异物杂质等沿着弧形的侧壁向远离开口的一侧移动，且在进气口的气流吹动下，使得异物杂质等向远离开口的一侧移动，从而使得异物杂质等不易从开口处逸出，集尘罩32在远离开口的一端为涡形，使得此处移动到异物杂质等被束缚，不易扩散，避免造成二次污染，定期对集尘罩32进行清理，将螺钉拧下，将对称的壳体分开，再将壳体中的杂质进行清理，清理完成后再安装到进风口2处，拧紧螺钉；通过设置细管5，使得集尘罩32和进风口2连通，空气在进风口2处流过时，进风口2处的气体流速加快，使得进风口2处的压强减小，使得细管5处产生负压，对异物杂质等进行吸引，进一步控制集尘罩32中异物杂质等移动，且在集尘罩32上安装防尘网51，将异物杂质等限制在集尘罩32中，防止异物杂质等从进风口2进入到风机本体1中，从而避免损坏叶轮。
