【摘要】:補(bǔ)連塔礦井下平衡式自動(dòng)風(fēng)門處在高負(fù)壓巷道內(nèi),2扇風(fēng)門反向啟閉,受風(fēng)門內(nèi)外壓差作用,接縫不嚴(yán)密漏風(fēng)大,安裝時(shí)需要掘進(jìn)風(fēng)門硐室,使用過程中依靠電能做為動(dòng)力容易導(dǎo)致事故;通過分析確定了風(fēng)門同向啟閉模式、氣動(dòng)、PLC控制系統(tǒng)等關(guān)鍵參數(shù);選用JISI型動(dòng)力驅(qū)動(dòng)氣缸等關(guān)鍵原件,研制了煤礦井下同向氣動(dòng)自動(dòng)風(fēng)門。風(fēng)門安裝時(shí)無需掘進(jìn)硐室,結(jié)構(gòu)簡單;風(fēng)門以井下現(xiàn)有壓風(fēng)系統(tǒng)控制實(shí)現(xiàn)自動(dòng)啟閉,安全節(jié)能,F(xiàn)場實(shí)踐應(yīng)用表明:風(fēng)門系統(tǒng)的2扇風(fēng)門同向啟閉,風(fēng)壓越大風(fēng)門關(guān)閉越嚴(yán)密,故障少維護(hù)比較方便,安全性能高,大大提升了井下通風(fēng)系統(tǒng)的可靠性。
[Abstract]:The balance automatic tuyere under the Fulianta mine is in the reverse opening and closing of two tuyere in the high negative pressure roadway, which is affected by the pressure difference between the inside and outside of the wind door, and the air leakage of the joint is not tight, so it is necessary to excavate the air door chamber when installing. In the process of using electric energy as power, it is easy to cause accidents; through analysis, the key parameters such as the codirectional opening and closing mode of the tuyere, pneumatic PLC control system and so on are determined; the key parts such as JISI type power drive cylinder are selected. In this paper, a codirectional pneumatic automatic tuyere in coal mine is developed. When the wind valve is installed, it does not need to dig into the chamber, and the structure is simple, and the tuyere can be automatically opened and closed by the control of the existing air pressure system. Safety and energy saving. The field practice shows that the two air doors of the air valve system are opened and closed in the same direction, the greater the air pressure is, the more close the air door is, the less the trouble is, the more convenient the maintenance is, and the safety performance is high, which greatly improves the reliability of the underground ventilation system.
