Technical Field

[0001] The utility model relates to the technical field of air filters, in particular to a cylindrical air filter with uniform air diversion. Background Art

[0002] A cylindrical air filter is a hollow cylindrical air filter. The cylindrical air filter completes air filtration by taking in air from the outside and discharging air from the center. The cylindrical air filter has a larger filtration area and is therefore commonly used in some large mechanical equipment.

[0003] To avoid the influence of rain, the cylindrical air filter is installed in the filter box of the equipment. The cylindrical air filter takes in air and discharges the filtered air through the filter box. An intake pipe is connected to the middle of the filter box. The side of the cylindrical air filter close to the intake pipe is used more frequently, while the part of the cylindrical air filter far from the intake pipe is used less for filtration, resulting in uneven use of the filtration of the cylindrical air filter and reducing the use effect of the cylindrical air filter.

[0011] In at least some embodiments, the lower connecting turntable is a disc-shaped structure, the upper connecting swivel is a hollow annular structure, the upper connecting swivel surrounds the outside of the opening at the top of the main frame, the main frame rotates circumferentially along the lower rollers of the upper connecting swivel and the upper rollers of the lower connecting turntable, the main frame and the inner air filter rotate synchronously in a circle, and each part of the rotating inner air filter takes turns to contact and filter the air at the air inlet, ensuring uniform filtration and consumption of each part of the inner air filter and the air.

[0012] The present utility model provides a cylindrical air filter with uniform flow guiding, having the following beneficial effects:

[0013] The outer flow guiding strips in a V-shaped structure guide the air flow outside the inner air filter.

The inner air filter material 102 is a circular tube-shaped structure and is made of materials such as non-woven fabric of polypropylene fiber and activated carbon. Rotating upper fixing rollers 103 are arranged in an annular array on the top of the main frame 1. The upper connecting rotating ring 2 slides circumferentially on the top of the main frame 1. An outer sealing convex ring 201 protrudes from the outer side of the upper connecting rotating ring 2. The outer sealing convex ring 201 is a circular ring structure protruding horizontally outwards. Rotating lower rollers 202 are arranged in an annular array at the bottom of the upper connecting rotating ring 2. The lower rollers 202 are in rotational contact with the top of the main frame 1. The bottom surface of the outer sealing convex ring 201 is in sliding contact with the top surface of the main frame 1. The upper fixing rollers 103 are in rotational contact with the top of the outer sealing convex ring 201. The lower rollers 202 reduce the rotational resistance of the main frame 1 and ensure smooth rotation of the main frame 1. The lower connecting rotating disc 3 slides circumferentially on the bottom of the main frame 1. Rotating upper rollers 301 are arranged in an annular array on the top of the lower connecting rotating disc 3. An upper sealing convex ring 302 protrudes from the outer side of the top of the lower connecting rotating disc 3. The upper sealing convex ring 302 is a circular ring structure protruding in the vertical direction. The inner vertical surface of the upper sealing convex ring 302 is in sliding contact with the outer vertical surface of the lower end of the main frame 1. The upper rollers 301 are in rotational contact with the bottom of the main frame 1. The upper rollers 301 reduce the rotational resistance of the main frame 1 and ensure smooth rotation of the main frame 1.

[0031] In an embodiment of the present disclosure, the outer flow guiding strips 101 are spiral-shaped curved plate-like structures. The outer flow guiding strips 101 protrude outside the main frame 1. The outer flow guiding strips 101 symmetrically form a horizontal V-shaped structure in the horizontal direction. The V-shaped spiral-structured outer flow guiding strips 101 guide the airflow outside the inner air filter material 102. The outer flow guiding strips 101 guide the airflow to flow axially upwards and downwards, promoting the airflow to uniformly pass through the upper and lower parts of the inner air filter material 102. Especially when the air enters from the middle, the outer flow guiding strips 101 guide the airflow to be divided into two parts upwards and downwards. The outer flow guiding strips 101 guide the airflow to uniformly pass through the upper, middle and lower parts of the inner air filter material 102, ensuring that the upper, middle and lower parts of the inner air filter material 102 uniformly carry out the air filtration process.

[0032] In an embodiment of the present disclosure, the lower connecting rotating disc 3 is a disc-shaped structure, and the upper connecting rotating ring 2 is a hollow annular structure. The upper connecting rotating ring 2 surrounds the outside of the opening at the top of the main frame 1. The main frame 1 rotates circumferentially along the lower rollers 202 of the upper connecting rotating ring 2 and the upper rollers 301 of the lower connecting rotating disc 3. The main frame 1 and the inner air filter material 102 rotate synchronously in a circle. Each part of the rotating inner air filter material 102 takes turns to contact and filter the air at the air inlet, ensuring that each part of the inner air filter material 102 uniformly filters and consumes the air.

[0033] Example 2. On the basis of Example 1, the outer flow guide strip 101 is of a spiral structure. The outer flow guide strip 101 spirally surrounds from the lower part of the main frame 1 to the upper part of the main frame 1. The spiral outer flow guide strip 101 guides the air flow to move up and down, promoting the uniform distribution of the air flow up and down.

[0034] Working principle of this embodiment: The main frame 1, the lower connecting turntable 3 and the upper connecting ring 2 are placed in the air filtering box body. The lower connecting turntable 3 is attached to the bottom of the box body. The top of the upper connecting ring 2 is connected and fixed to the air outlet pipe and communicated. External air enters from the outside. The air is filtered by the inner air filter material 102 and enters the inside of the main frame 1. The filtered air inside the main frame 1 is discharged through the pipe communicated with the upper connecting ring 2. The V-shaped spiral outer flow guide strip 101 guides the air flow outside the inner air filter material 102. The outer flow guide strip 101 guides the air flow to flow and divide axially up and down, promoting the air flow to evenly pass through the upper and lower parts of the inner air filter material 102. Especially when the air enters from the middle, the outer flow guide strip 101 guides the air flow to be divided into two parts up and down. The outer flow guide strip 101 guides the air flow to evenly pass through the upper, middle and lower parts of the inner air filter material 102, ensuring that the upper, middle and lower parts of the inner air filter material 102 uniformly carry out the air filtering process, avoiding the situation that the inner air filter material 102 is concentrated in one place for filtering while the other parts are used less for filtering, and improving the use effect of the cylindrical air filter element and prolonging the service life of the cylindrical air filter element.

[0035] While guiding the air flow, the outer flow guide strip 101 can also be pushed by the air flow and guide the main frame 1 to rotate circumferentially along the lower roller 202 and the upper roller 301. The main frame 1 and the inner air filter material 102 rotate synchronously in a circle. Each part of the rotating inner air filter material 102 takes turns to contact and filter the air at the air inlet, ensuring that each part of the inner air filter material 102 evenly contacts and filters the air, prolonging the service life of the cylindrical air filter element and improving the use effect of the cylindrical air filter element. The lower roller 202, the upper roller 301 and the upper fixed runner 103 reduce the rotation resistance of the main frame 1 and ensure the smooth rotation of the main frame 1.
