The working principle of the embodiment is as follows: when no dust exists in the ash hopper 3, the stop block on the inner wall of the discharging valve body 1 stops the excellent arc surface 11, the downward pulling of the heavy hammer 9 is prevented from making the excellent arc surface 11 turn over upwards, the heavy hammer 9 and the eccentric turning plate 6 keep a balanced state at the moment, the eccentric turning plate 6 separates the space in the discharging valve body 1, and the discharging opening at the position of the eccentric turning plate 6 is closed. When the dust in the ash hopper 3 gradually increases and reaches a certain amount (the difference between the gravity of the dust above the major arc surface 11 and the gravity of the dust above the minor arc surface 12 is greater than the pulling force of the heavy hammer 9), the major arc surface 11 turns downwards, the discharge opening is opened, the dust in the ash hopper 3 is discharged and gradually decreases, and the eccentric turnover plate 6 is reclosed due to the pulling of the heavy hammer 9 when the dust in the ash hopper 3 decreases to a certain amount, and enters the next cycle. The quantity of dust which can be stored in the ash hopper 3 and the discharging frequency and frequency of the discharging valve body 1 can be adjusted by adjusting the weight of the heavy hammer 9.

Example 2

Referring to fig. 3, the automatic discharging device for the dust remover comprises a discharging valve body 1, wherein the discharging valve body 1 is connected with an ash hopper 3 of the dust remover through a flange 2.
