【摘要】：大型礦用挖掘機濾筒式通風(fēng)除塵裝置的工作原理是在系統(tǒng)風(fēng)機的作用下,將含塵氣流通過濾筒過濾,把清潔空氣送入機棚內(nèi);同時,在濾筒上的灰塵通過脈沖閥清灰,落入灰斗被連續(xù)排出。本文對該裝置在實際應(yīng)用中發(fā)生的故障進行分析,從設(shè)計結(jié)構(gòu)入手,對裝置底架鋼結(jié)構(gòu)、風(fēng)帽結(jié)構(gòu)及其支撐、系統(tǒng)風(fēng)機室結(jié)構(gòu)、風(fēng)機安裝底座、螺旋輸送機等進行了優(yōu)化設(shè)計,優(yōu)化除塵器的清灰方式,對濾筒系統(tǒng)的控制程序進行了合理的調(diào)控。改進后的濾筒式通風(fēng)除塵裝置普遍應(yīng)用于系列大型礦用挖掘機的工作中,為提高大型挖掘機的出鏟率提供可靠保障。
[Abstract]:The working principle of the filter tube type ventilation and dust removal device of large mine excavator is to filter the dust-containing airflow through the filter barrel under the action of the system fan, and at the same time, the dust on the filter barrel is cleaned by pulse valve.Falling into the ash hopper is discharged continuously.In this paper, the failure of the device in practical application is analyzed. The steel structure of the device, the structure of the hood and its support, the structure of the fan chamber, the installation base of the fan and the screw conveyor are optimized from the design structure.The control program of filter tube system is controlled reasonably by optimizing the ash removal mode of dust collector.The improved filter tube type ventilation and dust removal device is widely used in the work of a series of large mine excavators, which provides a reliable guarantee for improving the shovel rate of large excavators.
