Description

Technical Field

[0001] This utility model relates to the field of filtration technology, and in particular to an air intake filter. Background Technology

[0002] Air intake filters are typically installed on the air intake duct of air purification systems, and also at the front end of the combustion chamber. Common filters include pre-filters (coarse filters) and post-filters (fine filters). Post-filters mostly use filter cloth, membranes, or screens for filtration. During the filtration process, dust particles trapped in the filter adhere to these materials, reducing airflow. Therefore, regular replacement is usually used to avoid this effect. Alternatively, reverse airflow can be used to clean the filter cloth, membrane, or screen to prevent dust from affecting airflow. The former method is more expensive, while the latter has the problem of poor cleaning effectiveness. Utility Model Content

[0003] This utility model provides an air intake filter to overcome the shortcomings of the prior art, and solves the problems of poor filtration effect and high cost of filter cloth, filter membrane or filter screen, and has strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted:

[0005] An air intake filter includes parallel flat plates arranged in the same direction, the width direction of the flat plates being parallel to the air intake direction, a pair of vertical plates welded between the flat plates, the vertical plates being vertically arranged, and concave shells riveted to the outer walls of the vertical plates, the concave shells being located between the flat plates.

[0006] The plate is provided with a first shaft and a second shaft that rotate at equal intervals along its length. The first shaft and the second shaft are located between the vertical plates. The first shaft is located at the rear end in the air intake direction, and the second shaft is located at the front end in the air intake direction. Each second shaft is located between every two adjacent first shafts. The filter cloth is in close contact with the first shaft and the second shaft. When the filter cloth passes through the first shaft and the second shaft, it forms multiple V-shaped structures, and the openings of two adjacent V-shaped structures on the filter cloth face opposite directions. The two ends of the filter cloth are respectively inserted into the vertical plates.

[0007] Furthermore, a rotating rod is provided in the cavity formed by the concave shell and the vertical plate. The two ends of the filter cloth are respectively fixed to the outer periphery of the rotating rod. The upper and lower ends of the rotating rod are respectively rotatably mounted on the flat plate. The upper end of the rotating rod is fixed with a rotating cap by a pin.

[0008] Furthermore, multiple V-shaped plates are welded between the plates, with both ends of the V-shaped plates abutting against the air outlet side of the filter cloth, and the V-shaped plates are positioned close to the first axis.

[0009] Furthermore, a rotating wheel is fixed to the upper end of the second shaft, and multiple rotating shafts are rotatably arranged on the plate. A driven wheel is fixed to the upper end of the rotating shaft. The rotating wheel and the driven wheel are driven by a belt. Spreading protrusions are symmetrically formed on the outer periphery of the rotating shaft. Swing shafts are symmetrically arranged on both sides of the rotating shaft. The upper and lower ends of the swing shaft are rotatably arranged on the plate. Swing plates are formed on the swing shaft. One end of the swing plate abuts against the outer periphery of the rotating shaft, and each pair of swing plates is located inside each V-shaped structure of the filter cloth.

[0010] Furthermore, the other end of the swing plate is formed with an arc strip.

[0011] Furthermore, an upper rotating plate is connected to the upper end of the swing shaft, and a spring is provided between each pair of upper rotating plates.

[0012] Furthermore, a rectangular hole is provided on the plate at the lower end, a rectangular plug is provided in the rectangular hole, a lower plate is provided at the lower end of the rectangular plug, pressure plates are respectively rotatably provided at both ends of the lower plate, and a connecting screw is rotatably provided at the outer end of the pressure plate, with the upper end of the connecting screw fixed to the plate at the lower end.

[0013] The advantages of the above technical solution are:

[0014] This invention uses a first shaft and a second shaft to form a V-shaped structure with multiple openings facing opposite directions on the filter cloth. This structure can effectively improve the filtration effect, and during the filtration process, the V-shaped structure design can prevent a large amount of dust from accumulating on the filter cloth and affecting the airflow.

[0015] This invention enables the filter cloth to move by rotating one of the rotating rods, and the rotating shaft to rotate during the movement. The spreading protrusion on the rotating rod allows the swing plate to swing around the swing shaft. When it swings, the arc strip on the plate can strike the filter cloth, thereby knocking off the dust on the filter cloth. At the same time, because the rotating rod is rotating, the filter cloth can be renewed, thereby increasing the air flow.

[0016] This invention also facilitates the discharge of dust. Attached Figure Description

[0023] Figure 6 The three-dimensional structure of the intake filter is shown. Figure 2 . Detailed Implementation

[0024] like Figures 1-6 As shown, an air intake filter includes parallel flat plates 10, the width direction of which is parallel to the air intake direction. A pair of vertical plates 12 are welded between the flat plates 10, the vertical plates 12 are vertically arranged, and a concave shell 1 is riveted to the outer wall of the vertical plates 12, the concave shell 1 being located between the flat plates 10.

[0025] A rotating rod 22 is provided in the cavity formed by the concave shell 1 and the vertical plate 12. The two ends of the filter cloth 21 are respectively fixed on the outer periphery of the rotating rod 22. The filter cloth 21 passes through the vertical plate 12. The upper and lower ends of the rotating rod 22 are respectively rotatably mounted on the flat plate 10. The upper end of the rotating rod 22 is fixed with a rotating cap 23 by a pin.

[0026] The plate 10 is provided with a first shaft 2 and a second shaft 20 that are rotatably arranged at equal intervals along its length. The first shaft 2 and the second shaft 20 are located between the vertical plates 12. The first shaft 2 is located at the rear end in the air intake direction, and the second shaft 20 is located at the front end in the air intake direction. Each second shaft 20 is located between every two adjacent first shafts 2. The filter cloth 21 is tightly attached to the first shaft 2 and the second shaft 20. When the filter cloth 21 passes through the first shaft 2 and the second shaft 20, it forms multiple V-shaped structures, and the openings of two adjacent V-shaped structures on the filter cloth 21 face opposite directions. The two ends of the filter cloth 21 are respectively inserted into the vertical plates 12.

[0027] Multiple V-shaped plates 28 are welded between the flat plates 10. The two ends of the V-shaped plates 28 abut against the air outlet side of the filter cloth 21, and the V-shaped plates 28 are positioned close to the first shaft 2.

[0028] A rotating wheel 24 is fixed at the upper end of the second shaft 20. Multiple rotating shafts 25 are rotatably arranged on the plate 10. A driven wheel 26 is fixed at the upper end of the rotating shaft 25. The rotating wheel 24 and the driven wheel 26 are driven by a belt 27. A spreading protrusion 250 is symmetrically formed on the outer periphery of the rotating shaft 25. A swing shaft 29 is symmetrically arranged on both sides of the rotating shaft 25. The upper and lower ends of the swing shaft 29 are rotatably arranged on the plate 10. A swing plate 30 is formed on the swing shaft 29. One end of the swing plate 30 abuts against the outer periphery of the rotating shaft 25. Each pair of swing plates 30 is located inside each V-shaped structure of the filter cloth 21. An arc strip 31 is formed at the other end of the swing plate 30.

[0029] The upper end of the swing shaft 29 is connected to an upper rotating plate 32. A spring piece 33 is provided between each pair of upper rotating plates 32. A rectangular hole is opened on the plate 10 at the lower end. A rectangular plug is provided in the rectangular hole. A lower plate 13 is provided at the lower end of the rectangular plug. Pressure plates 15 are rotatably provided at both ends of the lower plate 13. A connecting screw 14 is rotatably provided at the outer end of the pressure plate 15. The upper end of the connecting screw 14 is fixed to the plate 10 at the lower end.

[0030] In this embodiment, during air intake filtration, air flows along the width of the flat plate 10. When the air passes through the filter cloth 21, the dust in the air is filtered out by the filter cloth 21, and the filtered dust will accumulate in the V-shaped structure, thus improving the service life of the filter cloth 21.

[0031] In this embodiment, when cleaning the filter cloth 21, the operator rotates the rotating rod 22 that is not wrapped with the filter cloth 21, so that the rotating rod 22 drives the filter cloth 21 to wrap around it. During the wrapping process, the friction between the filter cloth 21 and the first shaft 2 and the second shaft 20 will cause each of the first shaft 2 and the second shaft 20 to rotate. When the second shaft 20 rotates, it will drive the rotating shaft 25 to rotate through the rotating wheel 24, the driven wheel 26 and the belt 27. The rotation of the rotating shaft 25 will cause the spreading protrusion 250 on it to periodically act on one end of the swing plate 30, so that the swing plate 30 rotates around the swing shaft 29, and the arc strip 31 moves away from the filter cloth 21, and the V-shaped spring piece 33 is also deformed. As the rotating shaft 25 continues to rotate, the force exerted on the swing plate 30 by the spreading protrusion 250 will gradually decrease, so that the swing plate 30 moves outward under the elastic force of the spring plate 33, and the arc strip 31 strikes the filter cloth 21, thereby achieving the purpose of knocking the filter cloth. During the knocking process, the dust on the filter cloth 21 can be knocked off until the used filter cloth 21 section is completely wrapped around the rotating rod 22. When the filter cloth 21 moves, the two ends of the V-shaped plate 28 will abut against the filter cloth 21 to scrape off the dust on the filter cloth 21. During the rotation, the pressure plate 15 needs to be rotated outward first, and the rectangular plug needs to be removed to open the rectangular hole, so that the dust can be discharged during the cleaning process.

[0032] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
