6.25 m Tamping Type Coke Oven Equipment Structure

Calculation and Optimization Improvement

Wang Peng

[Abstract]The 6.25 m tamping coke oven is a kind of tamping coke oven commonly used by domestic coking companies at this stage. Its components include a tamping machine， a coke blocking car， a coke pushing car， and a hydraulic switch. In order to respond to the call for energy saving and emission reduction and meet the requirements of environmental protection， it is necessary to optimize and improve the existing 6.25 m tamping coke oven equipment to achieve the purpose of energy saving and efficiency improvement. This article takes the 6.25 m tamping coke oven equipment of a coking plant as an example. First， it introduces the basic composition of the equipment and the main parameters of each part; then selects the coke car， the sidewall support of the coal trough， and the coal loading car to tamping the coal box 3 Section， a brief overview of the optimization and improvement content. Finally， based on the mechanical fatigue problem of the coke pushing rod， and on the basis of analyzing the reasons of mechanical vibration， corresponding shock absorption measures are proposed， which provide certain help for extending the service life of the coke pushing rod and improving the performance of the coke oven equipment.

1 6.25 m搗固型焦炉设备结构组成与参数

某焦化厂使用的6.25 m捣固型焦炉设备主要有拦焦车、装煤车、推焦车、熄焦车等组成。

（1）拦焦车位于焦炉操作台一侧的轨道上，主要功能为在推焦时用导焦栅将红焦炭导入熄焦车内，同时把出焦烟尘导入集尘干管。4台走行电机的功率均为30 kW，最大走行速度可达60 m/min;走行车轮直径为710 mm，共14个，每个车轮可承受最大压力320 kN;导焦运行周期设定为10 min;设有2台辅助除尘风机，功率为37 kW。

（2）装煤车的位置在焦炉机一侧，在装煤车运行过程中，煤塔内的洗精煤在摇动给料机的作用下，从煤塔下方的落料口掉入装煤车的煤槽中。同时，经过捣固机的处理，形成的煤饼通过运煤车进入焦炉内。……
