A total of four groups of transmission structures 345 are provided and are arranged in an array with the center of the ring 341 as the center of the circle, which is convenient for controlling the discharge speed of the discharge pipe of the self-filtering device 1.

[0024] Please refer to Figure 5, the utility model provides a three-channel fly ash self-filtering device. The transmission structure 345 includes a second gear 3451, a third tooth block 3452, a moving plate 3453, a sliding block 3454 and a sliding groove 3455. The second gear 3451 is meshed with the third tooth block 3452. The third tooth block 3452 is installed on the moving plate 3453. A sliding block 3454 is arranged on the right side of the moving plate 3453. The lower side of the sliding block 3454 is in sliding fit with the sliding groove 3455.

The moving plate 3453 is attached to the circular groove 2, which is beneficial to block the circular groove 2 through the moving plate 3453 and prevent fly ash from entering the interior of the outer shell 31.

[0025] The working principle is as follows:

[0026] First, first install the new device at the required position and conduct circuit connection. The fly ash of the fly ash tank truck is filtered to the storage pipeline through the self-filtering device 1. The impurity materials with large particle volume and heavy mass will fall downward under the block of the counterattack plate, while the powder materials will not fall but will continue to pass through the fly ash channel between the counterattack plate and the inner wall of the screening box body with the air flow and enter the storage pipeline. The impurity materials with large particle volume and heavy mass that fall will fall into the feed pipe and precipitate.

[0027] Second, control the motor 32 to operate. The output shaft of the motor 32 drives the first gear 33 to rotate. Since the first gear 33 is meshed with the first tooth block 343, the first gear 33 drives the first tooth block 343 to rotate. The first tooth block 343 drives the circular plate 341 to rotate, and the circular plate 341 drives the second tooth block 344 to rotate.

[0028] Third, since the second tooth block 344 is meshed with the second gear 3451, the second gear 3451 is meshed with the third tooth block 3542, the second tooth block 344 drives the second gears 3451 of the four groups of transmission structures to rotate respectively. The second gear 3451 drives the third tooth block 3542 to move. The third tooth block 3452 drives the moving plate 3453 to move. The moving plate 3453 moves under the limit of the sliding groove 3455 through the sliding fit of the sliding block 3454 and the sliding groove 3455, so that the moving plate 3453 exposes the circular groove 2, and then adjusts the opening diameter size of the circular groove 2, achieving the purpose of facilitating the adjustment of the discharging speed of the discharging pipe of the self-filtering device 1, being beneficial to the stability and accuracy of discharging, and being convenient for use.
