Semi-coke furnace capable of processing raw materials of pulverized coal

Abstract

A semi-coke furnace capable of processing pulverized coal raw materials, comprising a semi-coke furnace, the interior of the semi-coke furnace is provided with a carbonization chamber, the bottom of the carbonization chamber is provided with a flower wall, the middle of the carbonization chamber is provided with a partition wall, and the top of the semi-coke furnace is A silo is provided, the silo is in the shape of an inverted circular platform, and a coal block crushing device is installed in the silo, the coal block crushing device includes a rotating shaft, the top of the rotating shaft is rotatably connected with the silo, and the top of the rotating shaft is fixedly connected with the output shaft of the motor, the rotating shaft The bottom end is fixedly connected with a disc, and the disc is provided with an annular groove with an opening facing outward, and a plurality of springs are arranged in the annular groove. The beneficial effects of the present invention are: the motor drives the rotating shaft to rotate, the disc on the rotating shaft rotates, and the crushing plate inside the disc protrudes from the annular groove for a certain length under the action of centrifugal force, so that the other end of the crushing plate is in contact with the inner side wall of the silo contact with each other, and the pulverizing protrusions provided at the outer end of the pulverizing plate effectively pulverize the coal block.

Description

technical field [0001] The invention relates to the technical field of semi-coke furnaces, in particular to a semi-coke furnace capable of processing pulverized coal raw materials. Background technique [0002] Because the traditional semi-coke furnace uses air as the combustion-supporting gas and coal gas as the fuel, the hot gas after combustion of the gas is used as the heat source and heat carrier for the carbonization of semi-coke, resulting in excessive nitrogen and carbon dioxide content in the by-product gas of the semi-coke furnace. The gas is diluted, the calorific value decreases, the utilization value decreases, and it is easy to cause environmental pollution; in addition, the middle part of the existing semi-coke furnace has the function of pulverized coal processing, resulting in low coal treatment effect and difficult to meet the use requirements. Contents of the invention [0003] The object of the present invention is to provide a semi-coke furnace capable...
