【摘要】：燒結(jié)機料槽布料裝置是在燒結(jié)過程中按照生產(chǎn)工藝要求把混勻后的燒結(jié)混和料從料槽中布到燒結(jié)臺車上面。布料質(zhì)量直接影響著料面點火情況、煤氣消耗和固體燃料消耗,影響著成品燒結(jié)礦的質(zhì)量。 本文針對布料裝置的工藝要求和設(shè)備情況,確定布料閘門微調(diào)液壓系統(tǒng)控制方案。布料閘門控制由液壓缸驅(qū)動,所設(shè)計液壓系統(tǒng)采用電液伺服三通閥控制非對稱缸方式對閘門位置進行調(diào)節(jié)。同時確定了伺服系統(tǒng)主要元件規(guī)格和型號,建立了伺服系統(tǒng)的數(shù)學(xué)模型。 確定了積分分離PID控制策略。運用MATLAB軟件的Simulink工具包對閘門微調(diào)液壓伺服系統(tǒng)進行仿真,得到系統(tǒng)在時域內(nèi)的響應(yīng)曲線和頻域內(nèi)的Bode圖,并分析、計算了系統(tǒng)的動態(tài)特性和穩(wěn)定性。結(jié)果表明系統(tǒng)運行平穩(wěn)、響應(yīng)快,滿足混和料布料閘門啟閉及時、布料平穩(wěn)均勻的工藝要求。 本文還介紹了一種液壓油體積彈性模量的測量方法。最后說明布料裝置采用PLC自動控制系統(tǒng)。
[Abstract]:In the sintering process, the sintered material is distributed from the tank to the sintered car according to the requirements of the production process. The quality of the distribution directly affects the ignition of the material surface, the consumption of gas and solid fuel, and the quality of the finished sinter. In this paper, according to the technological requirements and equipment conditions of the distribution device, the hydraulic system control scheme for fine adjustment of the distribution gate is determined. The hydraulic control of the distribution gate is driven by the hydraulic cylinder. The hydraulic system adopts the electro-hydraulic servo three-way valve to control the unsymmetrical cylinder to adjust the position of the gate. At the same time, the specifications and models of the main components of the servo system are determined, and the mathematical model of the servo system is established. The integral separation pid control strategy is determined. The Simulink toolkit of MATLAB software is used to simulate the hydraulic servo system with fine tuning of the gate. The response curve in time domain and Bode diagram in frequency domain are obtained. The dynamic characteristics and stability of the system are calculated. The results show that the system runs smoothly, responds quickly, and meets the technical requirements of timely opening and closing of the mixing material gate and smooth and uniform distribution. This paper also introduces a method of measuring the bulk elastic modulus of hydraulic oil. Finally, the PLC automatic control system is used in the distribution device.
