Specific embodiments

[0024] As Figures 1-5 The utility model provides a kind of oil mist purifier with multi-stage filtering function, including air suction pipe 1, the end face of the bottom of air suction pipe 1 is fixedly connected with pipe 2 by bolt of thread connection, the inside of air suction pipe 1 is provided with filter assembly 3, filter assembly 3 includes shell 301, guide hopper 302, inclined pull rod 303, arc cover 304, motor 305, rotating shaft 306, fan blade 307, rotating rod 308, filter membrane 309, blade 310.

[0025] In an embodiment of the utility model, the inner wall of shell 301 is fixedly connected with guide hopper 302, the inner wall of shell 301 is fixedly connected with inclined pull rod 303, the end of inclined pull rod 303 away from shell 301 is fixedly connected with arc cover 304, shell 301 is sleeved on the inner wall of air suction pipe 1, the bottom of shell 301 is abutted with the top end face of pipe 2, guide hopper 302 is arranged in the shape of pyramid, the top end face of arc cover 304 is fixedly connected with rotating seat 4, rotating seat 4 is sleeved with rotating rod 308.

[0026] The output end of motor 305 is fixedly connected with rotating shaft 306, the side wall of rotating shaft 306 is fixedly connected with fan blade 307, motor 305 is fixedly connected on the top end face of air suction pipe 1, the side wall of air suction pipe 1 is fixedly connected with exhaust pipe 5.

[0027] The side wall of rotating rod 308 is sleeved with filter membrane 309, the side wall of rotating rod 308 is fixedly connected with blade 310, the side wall of air suction pipe 1 is fixedly connected with limiting strip 7, the side wall of filter membrane 309 is provided with limiting groove 6, limiting strip 7 is inserted with limiting groove 6, the side wall of rotating rod 308 is fixedly connected with limiting ring 8, limiting ring 8 is rotatably connected with filter membrane 309.

[0028] The bottom of rotating shaft 306 is fixedly connected with lug, the top end of rotating rod 308 is provided with groove, lug is clamped with groove, so that rotating shaft 306 rotates and drives rotating rod 308 to rotate.

[0029] The motor 305 drives the rotating shaft 306 to rotate, and the fan blade 307 sucks the air with oil mist through the smoke pipe 2, and the oil mist enters the air suction pipe 1 through the guide hopper 302. When the air passes through the guide hopper 302, the cross section of the flue is enlarged, and the flow rate of the air is reduced. The larger oil droplets are deposited into the storage tank between the guide hopper 302 and the inclined rod 303 due to gravity. At the same time, the arc-shaped cover 304 forms an obstacle to the flue. When the air flows around the obstacle, the oil droplets cannot turn with the airflow due to inertia, and impact the surface of the arc-shaped cover 304 and condense, and then flow along the edge of the arc-shaped cover 304 into the storage tank. The air continues to rise, and the rotating shaft 306 drives the rotating rod 308 and the blade 310 to rotate. The blade 310 separates the oil mist in the air by centrifugal force. Then the air is filtered by the filter membrane 309 again to separate the air and the oil mist completely. The multi-stage linkage and layer-by-layer filtration realize local purification and efficient exhaust. The front section removes most of the oil droplets, greatly reduces the risk of filter membrane 309 blockage, and prolongs the maintenance cycle of the device.

The water in the cavity 9 cools the arc-shaped cover 304, so that the oil mist can condense into droplets and be collected through the storage tank. When the water is heated, the hot water rises along the water pipe 10 into the water tank 11, exchanges heat with the outside through the fins 12, and the cold water descends through the water pipe 10 into the cavity 9, improving the separation efficiency of small oil mist particles, especially fine oil mist particles that are difficult to separate by conventional inertia collision. There is no pump or power supply, and the water flow is driven by temperature difference to circulate stably. The fins 12 increase the heat dissipation area and improve the heat exchange efficiency.

[0032] In the utility model, when using, the fan blade 307 inhales the air with oil mist through the pipe 2, the oil mist enters into the air suction pipe 1 through the guide hopper 302, when the air passes through the guide hopper 302, the cross section of the flue is enlarged, and then the flow rate of the air is reduced, the big oil drops are settled in the storage tank between the guide hopper 302 and the inclined pull rod 303 due to gravity, at the same time, the arc cover 304 constitutes the flue obstacle, when the air bypasses the obstacle, the oil drops cannot turn with the airflow due to inertia, impact the surface of the arc cover 304 and condense, then flow along the edge of the arc cover 304 into the storage tank, the air continues to rise, the rotating shaft 306 drives the rotating rod 308 and the blade 310 to rotate, the blade 310 utilizes rotation to make the oil mist be thrown to the inner wall of the air suction pipe 1 under the centrifugal force and flow downward to the storage tank, further separate the oil mist in the air, the rotating bolt, and then the pipe 2 can be disassembled, then the shell 301 and the rotating rod 308 can be taken off, at this time, the oil drops adhered on the pipe 2, the shell 301 and the blade 310 can be treated, the filter membrane 309 can be replaced, without disassembling the whole equipment or disconnecting the main air path, only need to twist the bolt to complete the separation, after disassembling, the internal surface oil dirt is completely cleaned.
