Feeding chamber for rotary kiln for calcining needle coke

Abstract

The invention relates to a feeding chamber for a rotary kiln for calcining needle coke. The feeding chamber comprises a feeding chamber body, a feeding device, a dust collecting hopper, a hot air outlet, an explosion venting valve and a temperature and pressure measuring pipe, the feeding device and the temperature and pressure measuring pipe are arranged at the top of the feeding chamber body, and a connecting port is reserved at the side, butted with the rotary kiln, of the feeding chamber body; and the explosion venting valve is installed on the upper portion of the side, opposite to a rotary kiln connector, of the feeding chamber body, the hot air outlet is reserved below the explosion venting valve, the dust collecting hopper is arranged on the lower portion of the feeding chamber body, and the bottom of the feeding device extends into the connecting port of the feeding chamber body and the rotary kiln. Compared with the prior art, the feeding chamber for the rotary kiln for calcining the needle coke has the beneficial effects that the matched feeding chamber is provided for the rotary kiln for calcining the needle coke; and by arranging a rotary kiln port butt-joint structure, the dust collecting hopper, the feeding device, an ash discharging device, an explosion venting device and the like, the problems encountered in the feeding process of the rotary kiln for calciningthe needle coke are solved.

Description

technical field [0001] The invention relates to the technical field of needle coke production, in particular to a feeding chamber for a rotary kiln for calcining needle coke. Background technique [0002] Needle coke is a high-quality material for manufacturing high-power and ultra-high-power electrodes. Graphite electrodes made of needle coke have strong thermal shock resistance, high mechanical strength, good oxidation performance, low electrode consumption and large allowable current density, etc. advantage. In addition to being used in electrodes, it can also be used in lithium-ion batteries, electrochemical capacitors, and nuclear graphite. Needle coke is a scarce product at home and abroad, so it is very promising to invent a production process for needle coke. [0003] The feeding chamber for the rotary kiln used to calcine needle coke is an important equipment in the needle coke calcination process. This equipment needs to solve the following problems: [0004] 1)...
