The traditional static chamber type coke oven coke oven, there is a serious environmental pollution, installed furnace coal pile density, blending demanding other defects, especially the modern large-scale coke-time investment is large, township enterprises and small and medium sized companies unable to invest for large Shanxi coal, coke soil coke and improved rapidly, causing a great waste of coal resources and land resources, environmental pollution to this end, the Shanxi provincial government attaches great importance to this, make every effort to develop the investment and the environment small pollution of the new oven. Dynamic continuous internal and external hybrid heating coke oven charging car roof using push coal stoker pushed downward, as the downward momentum of coal, while coal get tamping.In the dynamic vertical continuous coking process, coal is also to go through the expansion, the melting softening, semi-coke contraction process, due to the expansion of coal power and coal and furnace wall friction, resulting char not automatically down, reach the dynamic continuous coking purposes. To this end, we have designed a dynamic continuous vertical coke oven pushing coal. The dynamic continuous coking process requirements, the push coal powered hydraulic system. Hydraulic transmission with a compact, low inertia, smooth start, can in a wide range variable speed, which can effectively prevent overload, easy to automatic control and remote manipulation, etc., with a hydraulic pump powered hydraulic system, single rod as the hydraulic actuator cylinder. Push coal from the coal and coke matching cylinder piston push coal, bracket, pressed parts and other components.Push stoker coal cylinder material selection of cast iron or wear-resistant steel. Longitudinal side left coaling port, wide to the sides and bracket, the lower chamber is connected with the coke carbonization, and carbonization chamber size a match in the middle of the cylinder to push coal pistons, wear-resistant material selection of cast iron or steel，to match the size of the coal-cylinder, a piston rod connected to the hydraulic system in the middle of both sides of the bracket. Single rod cylinder by the piston rod, adjusting bolt, buffer sets, guide sleeve, cylinder, buffer heads, pistons, wear support ring, Bottom and seals and other components.
Dynamic continuous vertical furnace stoker push Bottom seamless welding cylinder made by the inner walls have a higher finish. The cylinder has A, B two ports, when the pressure oil into the mouth of people from A, B port back to the oil, the piston to the right to recover, while coal pushing the piston rises, plus coal; when the pressure oil into the mouth from B，A port back to the oil, the piston extends to the left drive to push the piston to push the coal down the coal, while coal compaction. This cylinder has a feed force when large, slow, while the return speed characteristics. To prevent dust from entering the cylinder, the piston rod is also a reliable dust-proof devices, and is equipped with a folding dust cover on the piston rod.
The presence of 50 tons of castings annealing furnace transformation of the former three problems: First, serious black smoke chimney, soot emissions 7 90 mg / m "[standard], serious pollution of the environment, and the second, the furnace temperature difference of about 1 00 ℃, the impact annealed cast iron quality, third, to high coal quality requirements, energy consumption. In response to these problems, the technological transformation of the annealing furnace.
First, the media machine combustion reciprocating push Soot is the fuel in the combustion process of the product. Combustion or not, not only has a direct impact on the smoke and dust, and to reduce consumption, save energy are closely related.After the bucket into the furnace chamber at high temperature flue gas heat radiation effect then gradually heated retort, ignition and combustion. The smoke produced by dry distillation heating mixing in the combustion zone and high temperature flue gas combustion and slag grate into the tail and turn to the secondary combustion air further. Therefore, before leaving the chamber most of the fuel is burned out and pressed into the studio in the micro-heating casting. So in the normal combustion, the chimney does not substantially black smoke. The use of a reciprocating push coal, 30 tons annealing furnace emissions of soot concentration increased from 790 mg / m "decline [standard] to 2 00 mg / m" [standard] or less. In addition, the reciprocating push stoker coal supply is more reasonable, in the course of coal supply, coal goes forward and squeezed slowly, stir, burn more thoroughly, and to regulate and control the temperature of both easy and reliable. Using reciprocating push coal, can burn for general coking and coking quality coal.
