Technical Field

[0001] This utility model relates to the field of filter material technology, and in particular to a particle dust conveying device for testing the performance of automotive air filters. Background Technology

[0002] Car air filters are devices primarily responsible for removing particulate impurities from the air. When a car engine is running, if the intake air contains dust or other impurities, it will accelerate the wear and tear on the parts. Therefore, the filtration performance of the filter material used to make the air filter indirectly determines the service life of the internal parts of the car engine.

[0003] In testing the filtration performance of air filter materials, a quantitative dust delivery method is generally used to simulate the amount of dust a car comes into contact with within a certain time. However, existing dust delivery mechanisms cannot accurately measure the amount of dust during the dust delivery process, resulting in a large error in each delivery and thus inaccurate filtration performance test results.

[0023] like Figures 1 to 8As shown, a particulate dust conveying device for testing the performance of automotive air filters is disclosed. The dust conveying device 1 includes a housing 101, a mounting plate 102, a nozzle 103, a connector 104, a connecting pipe 105, a support plate 106, a drive wheel 107, a driven wheel 108, a belt 109, a servo motor 110, and an auxiliary mechanism 111. A slot 2 is formed in the housing 101, and the mounting plate 102 is covered above the slot 2. The mounting plate 102 is fixedly connected to the upper surface of the housing 101. A support plate 106 is fixedly connected to the lower surface of the mounting plate 102, and several driven wheels 108 are mounted on the support plate 106. The driven wheels 108 on plate 106 are arranged from left to right as driven wheel 108-1, driven wheel 108-2, driven wheel 108-3, and driven wheel 108-4. Driven wheel 108-1 and driven wheel 108-2 are on the same horizontal line, while driven wheels 108-2, driven wheels 108-3, and driven wheel 108-4 are on the same inclined line. The driving wheel 107 is located between driven wheels 108-1 and driven wheel 108-2. The driving wheel 107 is fixedly connected to the output shaft of servo motor 110, and servo motor 110 is mounted on support plate 106. A belt 109 is installed on the driven wheels 108 and the driving wheel 107. The belt 109 has several arc-shaped grooves 13 for holding dust. Corresponding arc-shaped protrusions 14 are located on the drive pulley 107. These protrusions 14 can both drive the overall movement of the belt 109 and scrape off excess dust from the arc-shaped grooves 13. A second slot 3 is provided on the lower surface of the mounting plate 102 for the belt 109 to pass through. An auxiliary mechanism 111 is mounted on the mounting plate 102, and a third slot 11 is provided on the auxiliary mechanism 111, which communicates with the second slot 3. The auxiliary mechanism 111 is used to deliver dust into the arc-shaped grooves 13 on the belt 109. A nozzle 103 is provided on one side of the auxiliary mechanism 111. The nozzle 103 is fixedly connected to one end of the connecting pipe 105. The other end of the connecting pipe 105 extends from the mounting plate 102 into the empty slot 3. The connecting pipe 105 is fixedly connected to the mounting plate 102. Dust is transported by the belt 109 and then enters the nozzle 103 through the connecting pipe 105. A connector 104 is fixedly connected to the housing 101. One end of the connector 104 is connected to the nozzle 103 through a hose. The other end of the connector 104 is used to connect to the air pump. Compressed air is emitted from the air pump and enters the connector 104, and then sent to the nozzle 103 through the hose.

[0024] Furthermore, a stop block 4 is fixedly connected to the lower surface of the mounting plate 102, and the stop block 4 is used to cover the empty groove 3. The upper surface of the stop block 4 is in contact with the inner side of the belt 109, which makes the belt 109 more stable during movement. Two protrusions 5 are provided on the upper surface of the stop block 4. The two protrusions 5 are located on one side of the belt 109 and are in contact with the side wall of the belt 109, which can reduce the left and right swaying of the belt 109 during movement.

[0025] The auxiliary mechanism 111 includes a container 6, a support bar 7, a rotating rod 8, a lever 9, and a servo motor 10. The container 6 is fixedly connected to the mounting plate 102 and is used to hold dust. The support bar 7 is fixedly connected to the top of the container 6. One end of the rotating rod 8 is rotatably connected to the support bar 7, and the other end of the rotating rod 8 passes through the container 6 and the slot 3 and extends into the housing 101. The output shaft of the servo motor 10 is fixedly connected to the end of the rotating rod 8 that extends into the housing 101. The servo motor 10 is mounted on the support plate 106. A slot 11 is provided on the container 6, and the slot 11 communicates with the slot 3. Dust in the container 6 can enter the slot 3 through the slot 11. A lever 9 is placed on top of the empty slot 11, and the lever 9 is fixedly connected to the rotating rod 8. A baffle 12 is placed above the lever 9 and is fixedly connected to the receiving container 6. The initial position of the lever 9 is exactly above the empty slot 11, which can prevent the dust in the receiving container 6 from continuously entering the empty slot 11. The servo motor 2 10 controls the lever 9 to rotate 360° each time, scraping part of the dust in the receiving container 6 into the empty slot 11. Since the size of the empty slot 11 is fixed, the amount of dust scraped into the empty slot 11 each time the lever 9 rotates is the same, and the baffle 12 can prevent excess dust from entering the empty slot 11 during the movement of the lever 9.

[0026] Furthermore, a waist-shaped groove 15 is provided on the support plate 106, and the output shaft of the servo motor 110 slides in the waist-shaped groove 15. Waist-shaped grooves 16 are provided on both sides of the waist-shaped groove 15. The servo motor 110 is fixed to the support plate 106 by bolts and nuts. The bolts pass through the waist-shaped grooves 16. The position of the servo motor 110 can be adjusted by the movement of the bolts and nuts, thereby driving the movement of the drive wheel 107. This can avoid the situation of insufficient tension of the belt 109 after long-term use.

[0027] Furthermore, a baffle 17 is provided at one end of the housing 101, and a collection box 18 is fixedly connected to the bottom of the baffle 17. The collection box 18 is used to collect dust falling from the belt 109, and the error of this test can also be calculated based on the amount of dust remaining in the collection box 18. A handle 19 is fixedly connected to the baffle 17, and a limiting block 21 is fixedly connected inside the housing 101. The limiting block 21 is made of iron, and a magnet 20 is embedded in the baffle 17 to attract the limiting block 21 and fix the baffle 17.

[0028] The working principle of the utility model is as follows: The total amount of dust is poured into the receiving container 6. The rotation of the servo motor 10 drives the rotating rod 8 to rotate, which in turn drives the paddle 9 to rotate, scraping some of the dust from the receiving container 6 into the empty slot 11. Because the size of the empty slot 11 is fixed, the amount of dust scraped by the paddle 9 is the same for every 360° rotation. After entering the empty slot 2 3 from the empty slot 3 11, the dust falls into the arc-shaped groove 13 on the belt 109. The servo motor 110 drives the belt 109 to move, but the belt 10... When the dust on belt 9 is brought to the bottom of the connecting pipe 105, compressed air enters the nozzle 103 through the hose from the connector 104 and is then sprayed out from the nozzle 103. Since the connecting pipe 105 is connected to the nozzle 103, the dust on belt 109 will enter the nozzle 103 through the connecting pipe 105 and be sprayed out from the nozzle 103. Furthermore, due to the effect of the arc groove 13 and the baffle 12 on belt 109 and the protrusion 5 on the baffle 12, the dust is exceptionally stable during the conveying process and will not shake, causing a large amount of dust to fall off.
