Technical Field

[0002] An oil-mesh dust filter is a device used to filter particulate matter in the air. It is usually composed of multiple layers of metal meshes with different mesh sizes, which are coated with oil and placed in a metal frame. When air flows through the metal mesh, the dust will be stuck due to the adhesion of the oil and thus be filtered out. During the use of the oil-mesh dust filter, when dust falls on the oil mesh, the adhesion of the oil mesh will be reduced. Therefore, the more dust falls on the oil mesh, the worse the adhesion of the oil mesh will be. Therefore, as time goes by, the dust filtering effect of the oil mesh will deteriorate. Therefore, an oil-mesh dust filter with good dust filtering effect is needed to solve the above problems. Utility Model Content

The U-shaped fixing frame 10 on the blocking structure 9 is fixedly installed on the rear end of the blocking baffle 7, and the circular blocking plate 11 is located directly behind the air flow hole 8 opened on the blocking baffle 7. By arranging a large-particle dust deceleration blocking component 3 on the front side of the oil net component 2, the large-particle dust deceleration blocking component 3 can block the large-particle dust in the air, thereby decelerating the large-particle dust, and then causing the large-particle dust to fall under the influence of gravity after hitting the large-particle dust deceleration blocking component, and finally achieving preliminary filtration of the dust in the air, and at the same time, it can also reduce the dust falling on the oil net component 2, so that the oil net component 2 can maintain a good dust filtering effect for a long time, and finally the large-particle dust deceleration blocking component 3 and the oil net component 2 cooperate to make the dust filtering effect of the oil net dust filter better.

At this time, the blocking baffle 7 and the circular blocking plate 11 will decelerate the large-particle dust, and the decelerated The large dust particles at the back will fall into the dust collecting box 6 at the bottom due to gravity. At this time, the preliminary filtration of the polluted air is completed, so that the dust falling on the oil mesh component 2 on the rear side can be reduced, and the oil mesh component 2 can maintain a good dust filtering effect for a long time. Finally, the large dust deceleration and blocking component 3 and the oil mesh component 2 cooperate to make the dust filtering effect of the oil mesh dust filter better; when the polluted air passes through the air flow hole 8, it will enter the oil mesh component 2. At this time, the dust in the polluted air will adhere to the oil mesh component 2, and finally the air filtered by the oil mesh component 2 will flow out from the conical connecting shell 5 on the rear side.
