The ash blocking cover is opened, and the additive is put into the hopper. The motor is driven to drive the spiral rod to rotate, so that the spiral rod drives the additive to displace the blocking cover, so that a gap is generated between the blocking cover and the material guide pipe, and the additive is discharged from the gap. The speed of the motor is controlled to control the discharge speed, and multiple devices are used to achieve proportional batching. Compared with conventional hoppers, the stability of the internal environment of the additive storage is guaranteed.
[0008] Preferably, a reinforcement rod is fixedly connected to the middle of the support, so as to increase the stability of the support structure.
[0009] Preferably, the hopper includes a hopper body and a material guide shell, and the upper end of the material guide shell is fixedly connected to the lower end of the hopper body. After the additive is poured into the hopper body, the additive is introduced into the screw rod through the material guide shell, which facilitates the discharge of the screw rod.

[0015] 1. Open the ash cover, put the additive into the hopper, drive the motor to drive the spiral rod to rotate, so that the spiral rod drives the additive to discharge the cover, so that a gap is formed between the cover and the guide tube, and the additive is discharged from the gap. By controlling the speed of the motor, the discharge speed is controlled, and multiple devices are used to achieve proportional batching. Compared with conventional hoppers, the stability of the internal environment of the additive storage is guaranteed.
