[0002] Ash discharge valve is a valve used to discharge accumulated dust, usually used for dust removal, exhaust and emission control in industrial production. According to different use occasions and needs, ash discharge valves also have various types and characteristics. When the ash discharge valve is opened to discharge ash, due to the large amount of light dust, dust will be generated when the dust is discharged, resulting in a poor air environment on site. In addition, during long-term use, damp dust caused by air humidity, condensation and other reasons can easily adhere to the valve channel and cause blockage. For this reason, we propose a self-cleaning ash discharge valve. Utility Model Content

The ultrasonic transducer can also be controlled to operate at the same time. The ultrasonic transducer drives the vibration rod together with the scraper to vibrate, and the moistened dust attached to the valve channel and the inner side wall of the ash hopper can be effectively crushed, scraped and cleaned, avoiding long-term attachment that causes poor ash discharge and reduced capacity.

[0006] To improve the sealing effect:

[0007] As a further improvement of the above technical solution: a reinforced sealing ring plate is provided on the inner side of the valve channel, and a sealing matching boss is provided on the top of the control valve plate.

[0008] The beneficial effect of this improvement is that when the control valve plate is closed, the sealing ring plate and the sealing matching boss are tightened to play a role of secondary sealing.

The rotating fixed plate 19 and the scraper 22 can be used to avoid valve channel blockage, and the ultrasonic transducer 20 can be controlled to operate at the same time. The ultrasonic transducer 20 drives the vibration rod 21 together with the scraper 22 to vibrate, so that the moistened dust attached to the valve channel 1 and the inner side wall of the ash hopper 6 can be effectively crushed, scraped and cleaned, thereby avoiding long-term attachment that causes poor ash discharge and reduced capacity.

[0033] A reinforced sealing ring plate 3 is provided on the inner side of the valve channel 1 , and a sealing matching boss 4 is provided on the top of the control valve plate 2 .

[0034] When the control valve plate 2 is closed, the seal ring plate 3 and the seal matching boss 4 are tightly pressed against each other, thus playing a role of secondary sealing.

[0035] A first gear 9 is installed on the outer side of the hollow rotating shaft 8 . The first gear 9 is meshed with a second gear 10 . The top of the second gear 10 is connected to the output shaft of the motor 11 .

After the water enters the water distribution tray 15, it is evenly sprayed out in an appropriate amount through the nozzle 16 to humidify the dust. At the same time, the scraper 22 and the fixed plate 19 play a stirring role to make the dust evenly humidified. The dust accumulation inside the ash hopper 6 can be observed through the glass observation window 25. When the dust accumulates to a higher position, the cylinder 23 can be controlled to drive the piston rod to extend through The cooperation between the universal ball 24 and the universal ball mounting seat 5 pushes the control valve plate 2 downward to rotate and open, and discharges the moistened dust inside. Since the dust has been moistened, dust can be avoided during the discharge process. During the discharge process, the motor 11 is controlled to drive the rotating shaft 17 to rotate, driving the fixed plate 19 and the scraper 22 to rotate. The rotating fixed plate 19 and the scraper 22 can be used to avoid valve channel blockage, and the ultrasonic transducer 20 can be controlled to operate at the same time. The ultrasonic transducer 20 drives the vibration rod 21 together with the scraper 22 to vibrate, so that the moistened dust attached to the inner side wall of the valve channel 1 and the ash hopper 6 can be effectively crushed, scraped and cleaned, avoiding long-term attachment that causes poor ash discharge and reduced capacity.
