Abstract
The invention relates to a preheated coal leading-in device of a coal pyrolyzing furnace. Refractory material masonry (2) is arranged in a furnace mantle (1), eight blanking ports (9) are arranged on the refractory material masonry (2), the blanking ports (9) are connected with a material level control bin (10), a high material level gauge measuring hole (3), a low material level gauge measuring hole (4) and an observation hole (5) are arranged on the material level control bin (10), a raw coal gas pressure-measuring and temperature-measuring hole (6) is arranged on the furnace mantle (1), a heat insulation housing (7), a cement block (11) and a raw coal gas leading-out channel (12) are arranged below the material level control bin (10), and a heat insulation material (8) is arranged in the heat insulation housing (7). The interior is divided into two parts by the heat insulation housing filled with the heat insulation material, namely ceramic fiber, the external temperature is 600 DEG C, the internal temperature is 250 DEG C, the specific temperature required for leading preheated coal into the furnace can be met, and the preheated coal leading-in device can further save energy, improve efficiency and reduce cost.
Description
Technical field
The invention belongs to a kind of pit kiln, be specifically related to a kind of pre-hot coal gatherer of coal heat decomposition stove.
Background technology
The most of employing of pit kiln intermittent type coking in the market, coal in batches add coke oven, coal seam is arranged on the two ends of body of heater, and use coal not carry out preheating, but using independent equipment, coal is dry, and the scale of the equipment using is like this large, wasted the energy, service efficiency reduces greatly.
Summary of the invention
The pre-hot coal gatherer that is to provide a kind of coal heat decomposition stove of technical problem to be solved by this invention.Can be continuous, fast, pre-hot coal sent into pit kiln the carrying out coking of concentrated.
Technical scheme of the present invention: a kind of pre-hot coal gatherer of coal heat decomposition stove, it comprises: furnace shell 1, refractory materials masonry 2, high charge level instrumentation hole 3, low level gage gaging hole 4, vision slit 5, raw gas pressure measurement thermometer hole 6, insulation shell 7, lagging material 8, feed opening 9, material level control storehouse 10, cement block 11 and raw gas are derived passage 12.The inside of furnace shell 1 is provided with refractory materials masonry 2, on refractory materials masonry 2, be provided with 8 feed openings 9, feed opening 9 is connected with material level control storehouse 10, on material level control storehouse 10, be provided with high charge level instrumentation hole 3, low level gage gaging hole 4, vision slit 5, on furnace shell 1, be provided with raw gas pressure measurement thermometer hole 6,10 belows, material level control storehouse are provided with insulation shell 7, cement block 11 and raw gas and derive passage 12, and lagging material 8 is equipped with in the inside of insulation shell 7.
The present invention compared with prior art, there is following beneficial effect: material level control storehouse can be by the height of the material level of vision slit control coal, inside is divided into two portions by the insulation shell that lagging material ceramic fiber is housed, outside is 600 ℃, inside is 250 ℃, meets pre-hot coal and enters the required specified temp of stove, has saved the energy, improve efficiency, reduced cost.
