[0002] In order to reduce dust emissions in industrial production and protect the atmospheric environment, centrifugal dust collectors have been widely used in industrial production. Centrifugal dust collectors suck dust into themselves and adsorb the dust on their inner walls, thereby improving the air quality in industrial production.

[0026] Reference Figure 1-Figure 6 A centrifugal industrial dust collector comprises a body 1, a rotating rod 2 is vertically rotatably installed in the body 1, a plurality of mounting plates 3 are fixedly installed on the surface of the rotating rod 2 in a circumferential shape, a mounting opening is opened on the surface of the mounting plate 3, a plurality of spring rods 4 are horizontally fixedly installed in the mounting opening, a scraper 5 is slidably arranged in the mounting opening, and one end of the plurality of spring rods 4 is fixedly connected to the scraper 5;

[0027] A driving motor 6 is provided above the body 1, and the driving motor 6 is fixedly connected to the body 1 through a U-shaped connecting rod. The top end of the rotating rod 2 passes through the body 1 and is fixedly connected to the output shaft of the driving motor 6.

[0028] When the device is not in use, the multiple scrapers 5 do not contact the inner wall of the device body 1. When the drive motor 6 is started, the output shaft of the drive motor 6 rotates with the rotating rod 2, the multiple mounting plates 3 and the multiple scrapers 5. At this time, under the action of the centrifugal force of rotation, the multiple spring rods 4 will be stretched, so that the multiple scrapers 5 will move horizontally in the multiple mounting openings in the direction close to the inner wall of the device body 1 until they are against the inner wall of the device body 1. At this time, the scraper 5 will slide in contact with the inner wall of the device body 1 during the rotation, thereby scraping off the dust on the inner wall of the device body 1 to avoid excessive accumulation and affecting the dust removal effect of the device body 1. When the rotating rod 2 no longer rotates, the multiple scrapers 5 will quickly move and reset under the elastic potential energy of the multiple spring rods 4, and will no longer contact the inner wall of the device body 1.

[0029] The upper surface of the device body 1 is provided with a plurality of through grooves in a circumferential shape, and a plug rod 7 is vertically slidably inserted in the through grooves. A circular ring 8 is fixedly installed at one end of the plurality of plug rods 7 located in the device body 1. An inclined plate 9 is fixedly installed on the upper surface of the scraper 5. The lower surface of the circular ring 8 is arranged face to face with the inclined surfaces of the plurality of inclined plates 9. The plug rod 7 is connected to the device body 1 through a telescopic component. The telescopic component includes a telescopic spring 10 sleeved on the plug rod 7 and a mounting block 11 fixedly installed on the plug rod 7. The two ends of the telescopic spring 10 are respectively fixedly connected to the mounting block 11 and the device body 1. The plurality of plug rods 7 are controlled to reciprocate by a driving component. The driving component includes a slip ring 12 and a plurality of slide plates 13 fixedly installed on the outer ring wall of the slip ring 12 in a circumferential shape. A reciprocating thread is provided on the top surface of the rotating rod 2. The slip ring 12 is threadedly sleeved on the top of the rotating rod 2. The plurality of slide plates 13 are respectively slidably sleeved on the plurality of plug rods 7.

[0030] When the rotating rod 2 rotates, the slip ring 12 threadedly sleeved on the rotating rod 2 will carry the multiple slide plates 13 to reciprocate in the vertical direction. When the multiple slide plates 13 move to respectively abut against the multiple mounting blocks 11, the multiple insertion rods 7 are subjected to the downward pressure and move downward together, and then the multiple telescopic springs 10 will shrink, and the ring 8 at the bottom end of the multiple insertion rods 7 will move downward, and its lower surface will slide in contact with the inclined surfaces of the multiple inclined plates 9. Under the pressure of the inclined surfaces, the multiple Under the action of centrifugal force, the scrapers 5 whose ends are in contact with the inner wall of the body 1 will all move toward the direction close to the rotating rod 2, that is, the ends are no longer in contact with the inner wall of the body 1, that is, when the multiple scrapers 5 are rotating, they will not always contact with the inner wall of the body 1, but will contact intermittently, because there is no need to clean the dust accumulated on the inner wall of the body 1 all the time, and it is only necessary to clean it intermittently, so as to avoid the scrapers 5 from always sliding in contact with the inner wall of the body 1, which will cause rapid wear and shorten the service life of the scrapers 5;

[0031] Then, as the multiple slides 13 move upward, the pressing force applied to the insertion rod 7 will gradually disappear, and the multiple insertion rods 7 will move upward together with the ring 8 under the elastic potential energy of the multiple telescopic springs 10, and then the pressing force applied by the ring 8 to the multiple inclined plates 9 will gradually disappear, and the multiple scrapers 5 will contact the inner wall of the device body 1 again under the action of centrifugal force.

[0032] A folding curtain 14 is provided between one end of the scraper 5 and the wall of the mounting opening, and both ends of the folding curtain 14 are fixedly connected to the end surface of the scraper 5 and the wall of the mounting opening respectively. The folding curtain 14 can prevent dust entering the device body 1 from entering the mounting opening.

[0033] A plurality of scraper strips 15 are provided on the left and right side walls of the mounting plate 3, and the plurality of scraper strips 15 on one side of the mounting plate 3 are fixedly connected by a connecting rod 16. Slide openings are provided on the left and right side walls of the mounting plate 3, and sliding blocks 17 are fixedly installed on the left and right side walls of the scraper 5. The ends of the two sliding blocks 17 that are away from each other pass through the two sliding openings respectively, and are fixedly connected to the two scraper strips 15 respectively, and the scraper strips 15 are in sliding contact with the mounting plate 3;

[0034] When the scraper 5 moves in the horizontal direction, the multiple scraper strips 15 located on both sides of the mounting plate 3 will also move in the horizontal direction together, thereby achieving the effect of scraping off the dust attached to the side wall of the mounting plate 3, avoiding that some dust attached to the side wall of the mounting plate 3 cannot be effectively cleaned.

[0035] In the utility model, when the device is not in use, the multiple scrapers 5 do not contact the inner wall of the device body 1. When the drive motor 6 is started, the output shaft of the drive motor 6 rotates with the rotating rod 2, the multiple mounting plates 3 and the multiple scrapers 5. At this time, under the action of the centrifugal force of rotation, the multiple spring rods 4 will be stretched, so that the multiple scrapers 5 will move horizontally in the multiple mounting openings in the direction close to the inner wall of the device body 1 until they are against the inner wall of the device body 1. At this time, the scraper 5 will slide in contact with the inner wall of the device body 1 during the rotation process, thereby scraping off the dust on the inner wall of the device body 1 to avoid excessive accumulation and affecting the dust removal effect of the device body 1.
