Automatic charging apparatus for a furnace

An automatic charging apparatus for a furnace, comprising:

• a hopper provided with an inlet opening and an outlet opening;
• a buffer bin in which a buffer channel is provided, one end of the buffer channel being provided with a discharge port communicating with the outlet opening, another end of the buffer channel being in communication with a feeding inlet of a furnace;
• and
• a pushing mechanism configured to push feedstock in the buffer channel sequentially into the feeding inlet of the furnace, the pushing mechanism comprising a drive and a pushing element, the drive driving the pushing element to perform a reciprocating movement in the buffer channel such that the feedstock in the buffer channel is sequentially pushed into the feeding inlet via the reciprocating movement of the pushing element;
• wherein a storage channel is inclinedly provided in the buffer bin, the storage channel being disposed above the buffer channel, an upper end of the storage channel being in communication with the outlet opening, a lower end of the storage channel being in communication with the buffer channel;
• and
• wherein a plurality of the storage channels are provided, the plurality of storage channels being successively arranged in a vertical direction;
• and in two neighboring storage channels, a lower end of an upper storage channel is in communication with an upper end of a lower storage channel.
