[0002] The outlet of the temporary storage and storage silo of powder materials is generally set at the bottom. The bottom of the silo is a conical structure, which is convenient for discharging from the bottom during discharge. However, when using conventional discharging devices for discharging, powders are prone to sticking and blocking the discharge port, or causing the discharging process to be unsmooth.

The diverter cone 2 is narrow at the top and wide at the bottom, and the contact surface with the powder is an inclined surface. After the outlet end is opened, the pressure on the powder at the lower end is increased, so that it can be discharged quickly and the agglomerates are crushed at the same time. The cutting of the moving powder by the cutting column 3 can effectively prevent the outlet end from being blocked.

[0020] A first limiting structure is provided at the right end of the first plug plate 6 and the tail is connected to the end plate 20 by bolts. When the first limiting structure contacts the right end side wall of the diverter box 4, the first through hole 16 is docked with the main flow channel 12.
