AI Technical Summary
Powder is prone to clumping and forming arches in the silo, which prevents the material from flowing normally. Existing technical solutions increase the length of the silo or require manual intervention, which has the problems of large space requirements and high costs.
An agitator is installed on the valve plate of the electric butterfly valve. The agitator rotates in the hopper to break up the powder arch. Compressed air is introduced through the vent pipe to assist the flow of powder.
It enables the smooth flow of powder without altering the shape of the silo, avoids damage to the outer wall of the silo, and reduces the difficulty and cost of installation and maintenance.

Abstract
Claims
1. A double-cone blender arch-breaking device comprising a bin, characterized by: The hopper is in the shape of a double cone. The upper end of the hopper is provided with a feed inlet and the lower end of the hopper is provided with a discharge outlet. An electric butterfly valve for controlling the material discharge speed is provided at the discharge outlet. A stirring rod is provided on the valve plate of the electric butterfly valve. The stirring rod rotates back and forth in the hopper under the drive of the valve plate.
2. A double-cone blender arch-breaking device as defined in claim 1, wherein: The stirring rod is U-shaped, and the open end of the stirring rod is installed on one side of the valve plate's central axis and is parallel to the valve plate's central axis.
3. A double-cone blender arch-breaking device as defined in claim 1, wherein: The cross-section of the stirring rod is spindle-shaped.
4. A double-cone blender arch-breaking device as defined in claim 1, wherein: The inner wall of the silo is fitted with an inner lining plate made of polytetrafluoroethylene.
5. A double-cone blender arch-breaking device as defined in claim 1, wherein: The silo is equipped with a ventilation pipe.
6. A double-cone blender arch-breaking device as defined in claim 1, wherein: The outer surface of the hopper is provided with reinforcing ribs.
