Description

TECHNICAL FIELD

[0001] The utility model relates to long flame coal production technical field, concretely is a long flame coal carbonization rotary furnace feed bin. BACKGROUND

[0002] Hard carbon is considered to be the most promising anode material for sodium-ion batteries. The choice of precursor is crucial in the preparation of hard carbon materials. Among the developed raw materials, long flame coal is a highly potential high-performance-price ratio hard carbon precursor due to its abundant reserves and high carbon content. The manufacturing process basically includes the following steps: first, the long flame coal is crushed to below 20 microns, then the "melting-carbonization" process is changed to a "cross-linking-carbonization" process through oxidation cross-linking; then, coal-based hard carbon materials are prepared through carbonization treatment, and finally, the obtained hard carbon is crushed again to optimize its particle size distribution, and the final hard carbon anode material is obtained.

[0003] According to the search of the publication number: CN212870701U, a rotary furnace feeder with feeding and cleaning functions is disclosed. In this technology, a rotary furnace feeder with feeding and cleaning functions is disclosed, which includes a feeder box, a rack, a feeding screw shaft and a feeding drive. The feeder box is installed on the rack, the upper end of the feeder box is provided with a feeding port, a gas outlet and an inlet for introducing protective gas, the lower end is provided with a discharge pipe, the feeding drive is installed on the rack, one end of the feeding screw shaft is connected with the feeding drive, the other end extends into the feeder box and extends into the discharge pipe, the feeder box is provided with an upper feeding position meter and a lower feeding position meter below the upper feeding position meter, the lower feeding position meter is located above the feeding screw shaft, the feeding port is provided with a feeding valve.

[0004] If long flame coal is carbonized or oxidized by a rotary furnace, the oxidized material will enter the material bin of the carbonization furnace after being crushed.

The conventional method uses stirring or knocking hammer, but continuous use of the knocking hammer to knock the same position may cause damage to the bin wall. If stirring is attempted, the bridging often occurs at the outlet of the bin, and the stirring blades cannot reach this position, so it is also difficult to effectively solve the problem.
