With the effect of lifting crawler belt, Caterpillar belt span is big, can avoid scratching of flitch and furnace bottom, it is achieved that material divides small lot continuous discharge,
Scraper efficiency is high, and continuity is good, it is to avoid the rolling of semicoke material, pushes and causes pulverizing, and greatly reduces high-temperature semi-coke after pyrolysis
Degradation rate during discharging.
(2) technical scheme
The invention provides a kind of pyrolysis of coal revolving bed drawing mechanism, including driving shaft and one or more driven shaft, described master
Connected by crawler belt between moving axis and described driven shaft, outside described crawler belt, be provided with multiple equally distributed material scraping plate.
Further, the angle between described material scraping plate and described crawler belt is 45 °～90 °.
Further, described crawler belt along pyrolysis of coal revolving bed radial direction and be perpendicular to revolving bed put flitch dispose.
Further, described crawler belt and described material scraping plate are just made up of heat-resistant antifriction, normally can work under 1000 degrees Celsius.
Further, with gear on described driving shaft and described driven shaft, it is connected with crawler belt.
Further, described track length is 1000mm～20000mm, and width is 40mm～1000mm.
Further, described drawing mechanism also includes frequency control motor, and described frequency control motor drives described driving shaft to rotate.
Further, described driving shaft and described driven shaft are hollow shaft, and it is internal is cooling water cavity, and cooling water cavity two ends are respectively
Being provided with water inlet pipe and outlet pipe, cooling water cavity is connected by swivel joint respectively with water inlet pipe and outlet pipe.
(3) beneficial effect
The invention provides a kind of pyrolysis of coal revolving bed drawing mechanism, the high-temperature semi-coke after pyrolysis of coal continuously, is completely scraped flake hearth-tapping
A kind of output device, it is achieved that pyrolysis char divides small lot, Large-Span Continuous discharging, it is to avoid material rolling, pushes and causes
Pulverizing, scraper efficiency is high, and continuity is good, greatly reduces the degradation rate of material during discharging.
The present invention uses multiple driven shaft and crawler belt and revolving bed to put the vertically arranged mode of flitch, adopts inside driving shaft and driven shaft
By logical cooling water water-cooled, reducing the heating temperature of axle, driven shaft gear is engaged lifting with crawler belt, it is achieved that revolving bed pyrolysis of coal
The large span of device thermal decomposition product, distance, the discharging of high-temperature material.
Outside crawler belt, the material scraping plate of 45 °～the 90 ° angle multiple heat resistant and wear resistant materials of installation, puts the pyrolysis on flitch revolving bed high
Temperature product semicoke divides small lot continuous discharge, and scraper efficiency is high, and continuity is good, it is to avoid semicoke rolling, pushes and causes pulverizing,
Greatly reduce the degradation rate of material during discharging.
