如图1至图3所示,本实用新型所提供的旋风分离装置的工作过程是这样的:As shown in FIG. 1 to FIG. 3, the working process of the cyclone separation device provided by the present invention is as follows:
在尘桶100的出风口102位置设有风机(图中未示出),在风机的作用下气液混合气流通过一级进风口101进入到尘桶100中,一级进风口101包括切向的进风气道,气流进入后在尘桶100内产生旋风分离。混合气流中的液体在离心力的作用下,通过网孔过滤器300的阻挡被分离出大部分,并收集到尘桶100的底部,还有一部分水汽会依次通过网孔过滤器300和二级进风风道进入到多锥过滤器200中。结合图3所示,水汽在多锥过滤器200的进风气流作用下从高效进风口220进入到高效锥250中,通过高效锥250的高效旋风将剩余的水汽分离到内尘桶400中,空气则从高效出风口240进入到尘桶100的出风口102,从而进入风机。在工作过程中,随着积水量的增加,留存在尘桶100内部的积液水位不断上升,对浮子110产生浮力,当浮子110在积液的浮力作用下上升到二级进风口处时,其顶端将二级进风口堵住,使高效锥250停止工作,尘桶100内的气流消失,整机不能够继续吸水,有效防止积液从尘桶100中溢出,避免了积水被吸入电机室,确保使用安全。随后,使用者可以在停机状态下将设置在尘桶100底部的底盖(图中未示出)打开,使尘桶100和内尘桶400内部的积液手动排出,将其内部清洁后静置等待下次的使用。 A fan (not shown) is disposed at the air outlet 102 of the dust bucket 100. Under the action of the fan, the gas-liquid mixed airflow enters the dust bucket 100 through the first air inlet 101, and the first air inlet 101 includes a tangential direction. The inlet air duct generates a cyclone separation in the dust bucket 100 after the airflow enters. The liquid in the mixed gas stream is separated by the blockage of the mesh filter 300 by the centrifugal force, and is collected to the bottom of the dust bucket 100, and a part of the water vapor passes through the mesh filter 300 and the secondary filter in turn. The wind tunnel enters the multi-cone filter 200. As shown in FIG. 3, the water vapor enters the high efficiency cone 250 from the high efficiency air inlet 220 under the action of the air flow of the multi-cone filter 200, and the remaining water vapor is separated into the inner dust barrel 400 by the high efficiency cyclone of the high efficiency cone 250. The air enters the air outlet 102 of the dust bucket 100 from the high efficiency air outlet 240 to enter the fan. During the working process, as the amount of accumulated water increases, the level of the liquid remaining inside the dust bucket 100 rises continuously, generating buoyancy to the float 110, and when the float 110 rises to the secondary air inlet by the buoyancy of the accumulated liquid The top end of the second air inlet is blocked, so that the high efficiency cone 250 stops working, the airflow in the dust bucket 100 disappears, the whole machine can not continue to absorb water, effectively preventing the liquid from overflowing from the dust bucket 100, and preventing the water from being sucked in. The motor room ensures safe use. Subsequently, the user can open the bottom cover (not shown) disposed at the bottom of the dust bucket 100 in the stopped state, and manually discharge the liquid inside the dust bucket 100 and the inner dust bucket 400, and then clean the interior thereof. Wait for the next use.
实施例二Embodiment 2
除了上述实施例一的结构之外,在实际应用中,二级进风口的设置可以通过多种方式来实现。图4为本实用新型旋风分离装置实施例二的剖视图。在图4所示的实施例中,为了方便设置气流通道,在所述多锥体201的下方设有一隔板202,所述隔板202上开设有风道口203,该风道口203即为本实施例中的二级进风口,所述多锥过滤器200通过该风道口203进风。也就是说,一级进风口101通过风道口203和高效进风口220连通。气液混合气流由高效进风口220进入高效锥250内部时产生旋风,进行气液分离,多个高效锥250通过多个开口270向中心聚拢在内尘桶400的顶部,使分离出的液体顺利流入内尘桶400。分离后的气体通过设置在高效锥250直径较大的一端的锥孔盖230上的高效出风口240排出,并通过尘桶100的出风口102进入风机。同样地,当留存在尘桶100内部的积液水位上升时,浮子110也随之上升,浮子110的顶端将风道口203堵住,尘桶100内气流消失,积液则不会上升后从尘桶100中溢出。为了更好地密封,浮子110的顶端形状与风道口203对应设置,如图4所示的实施例中,风道口203为环状,则浮子110的顶端也对应设置为环状。更进一步地,浮子110的形状也可以根据内尘桶400的外壁和网孔过滤器300的内壁所夹设的空间形状进行适应性选择,确保其顶部与二级进风风道的二级进风口形状、位置对应设置即可。In addition to the structure of the first embodiment described above, in practical applications, the setting of the secondary air inlet can be realized in various ways. Figure 4 is a cross-sectional view showing the second embodiment of the cyclone separation device of the present invention. In the embodiment shown in FIG. 4, in order to facilitate the installation of the air flow passage, a partition 202 is disposed below the multi-cone 201, and the air gap 203 is opened on the partition 202, and the air passage 203 is In the secondary air inlet of the embodiment, the multi-cone filter 200 enters the air through the air passage 203. That is, the primary air inlet 101 communicates with the high efficiency air inlet 220 through the air duct opening 203. When the gas-liquid mixed gas flow enters the inside of the high-efficiency cone 250 from the high-efficiency air inlet 220, a cyclone is generated to perform gas-liquid separation, and the plurality of high-efficiency cones 250 are gathered toward the center of the inner dust barrel 400 through the plurality of openings 270, so that the separated liquid is smoothly passed. Flow into the inner dust bucket 400. The separated gas is discharged through the high-efficiency air outlet 240 provided on the tapered hole cover 230 at the end of the high-efficiency cone 250 having a large diameter, and enters the fan through the air outlet 102 of the dust bucket 100. Similarly, when the liquid level remaining inside the dust bucket 100 rises, the float 110 also rises, the top end of the float 110 blocks the air passage opening 203, and the airflow in the dust bucket 100 disappears, and the liquid accumulation does not rise. The dust bucket 100 overflows. For better sealing, the tip shape of the float 110 is provided corresponding to the air passage opening 203. In the embodiment shown in Fig. 4, the air passage opening 203 is annular, and the top end of the float 110 is also provided in a ring shape. Further, the shape of the float 110 can also be adaptively selected according to the spatial shape of the outer wall of the inner dust bucket 400 and the inner wall of the mesh filter 300, ensuring the secondary entry of the top and secondary air inlet ducts. The shape and position of the tuyere can be set.
