Description

Hyperbola raw coal bin with bin separation function Technical Field The utility model relates to the technical field of coal bunker blocking prevention, in particular to a hyperbolic raw coal bunker with a bunker separating function. Background Along with the social development of coal materials or other materials used by factory enterprises, the coal materials or other materials used are diversified, one important step in use of the coal materials or other materials is conveying, and at present, a bin body feeding mode is mostly adopted, but in the feeding process of the bin body, the blocking and bonding phenomena always occur in the bin body due to the fact that the coal materials or other materials contain mud or contain large water, the blocking and bonding are more serious along with the continuity of conveying materials, the safe and stable operation of a unit is seriously affected, and the conveying and production efficiency is greatly reduced. For the bin, a hopper is generally adopted, the inlet is large, the outlet is small, the section of a coal outlet is small, a gate valve is used for switching, and the method has the defects that if the bin is blocked in a production peak period and is not blocked in time, even if the gate valve is opened, materials cannot fall down to affect normal production, the conventional hopper relies on gravity to fall coal, and in use, the materials are accumulated on the surface of the wall of the hopper greatly due to friction force between the hopper and the wall of the hopper, so that the accumulation force of the materials is increased, the discharging speed of the coal is greatly influenced, and particularly, the phenomenon that the coal is stuck to the wall or shed coal is greatly increased in the flowing process under the condition that the coal has humidity to affect the normal flowing and blanking efficiency of the coal.
