Cyclone separation filter module

The invention relates to a filter module, in particular to a filter module for separating airflow and foreign matter by using a cyclone principle.

Referring to FIG. 1 , a conventional filter module 1 generally includes a cylindrical member 11 , a top end cover 12 , a bottom end cover 13 , and an impeller 14 . The tubular member 11 defines a vortex chamber 110 around an axis L and has a top end portion 111 and a bottom end portion 112 disposed oppositely. The top end cover 12 and the bottom end cover 13 detachably close the top end portion 111 and the bottom end portion 112 of the cylindrical member 11, respectively. The top cover 12 has a double-ring edge 123 formed on two opposite sides along the direction of the axis L and defining an air inlet 121 and an air outlet 122, respectively, and an air gap is formed on the inner surface. 121 and the barrier ribs 124 that are not in communication with the exhaust port 122. The impeller 14 is mounted between the tubular member 11 and the end cover 12, and includes a wheel frame 142 defining a hole 141 around the axis L, and a plurality of blades 143 formed on the circumference of the wheel frame 142 and arranged in a spiral radial shape. And a plurality of gaps 144 formed between the vanes 143, respectively. The tunnel 141 communicates with the exhaust port 122 and the vortex chamber 110. The gaps 144 communicate with the air inlet 121 and the vortex chamber 110.

When the foreign matter such as oil mist, black smoke, dust or exhaust gas enters the air inlet 121 of the top cover 12 in the direction of the solid arrow, it is blocked by the partition rib 124, and the edge of the blade 143 of the impeller 14 is blocked. A gap 144 formed in the tangential direction enters the vortex chamber 110 of the cylindrical member 11. At this time, the airflow entering the vortex chamber 110 generates a cyclone action in the vortex chamber 110, as shown by the ribbon arrow in the figure, and centrifugal force is used to throw out the foreign matter brought in by the airflow, so that the foreign matter is along The wall surface of the tubular member 11 is dropped and deposited on the bottom end portion 112 of the cylindrical member 11, and finally the air flow having no foreign matter is discharged to the discharge opening 122 of the end cover 12 via the opening 141 of the impeller 14.

However, the above-mentioned filter module 1 generates a centrifugal force by simply passing through a cyclone, and only has the effect of throwing and separating the foreign matter having a certain weight or a certain volume or more in the airflow, so how to capture the smaller foreign matter in the filtered airflow, It is a common problem that the industry needs to solve.

Accordingly, it is an object of the present invention to provide a cyclonic separation filter module that is capable of effectively capturing smaller foreign matter in the filtered gas stream.

Therefore, the cyclone separation filter module of the present invention comprises a cylindrical unit, an end cap unit, at least one guiding tube member, at least one catching member, and at least one first impeller.

The barrel unit surrounds a vortex chamber.

The catching member is mounted on the tubular unit and adjacent to the first end cover and traverses the vortex chamber. The catching member includes a body and a plurality of openings disposed through the body.

The first impeller is mounted on the tubular unit and is located in the vortex chamber and is located between the catching member and the guiding tubular member.

The effect of the invention is that the arrangement of the catching member is used to greatly increase the probability of intercepting the foreign matter entrained by the airflow entering the vortex chamber through the air inlet, thereby making the weight or particle diameter of the foreign matter smaller. The foreign matter can be accumulated into a large weight or a particle size, so that the foreign matter entrained by the air flow can be thrown and removed by centrifugal force under the action of the cyclone generated after the first impeller, thereby solving the conventional knowledge. The filter module simply generates centrifugal force through the cyclone, and it is impossible to capture the problem of filtering out the foreign matter of the weight or the particle size too small in the airflow.
