钒钛磁铁矿脱磁器的硬件设计.doc

　 摘 要　 我国一些铁矿选矿广试用了脱磁技术，它初步显示出重要作用。改善了选矿技术经济指标，保证新工艺的顺行，本文根据细粒磁性物回收工艺中需要使用脱磁器的要求，首次提出磁场强度高、能耗低、高性价比、具有自适应控制功能的脉冲脱磁器的研究和设计。本文主要开展了以下研究工作。　　　　　　　　　　　　　　　　　　　　　Abstract　 Based on magnetite fine powder recycling technology needs, The first this paper research and design the demagnetize implement with high magnetic field intensity, low power consumption, cost, adaptive control and so on. The paper carried out the following studies:　 Firstly, this paper research the mechanism of demagnetizes. the first design the system structure of pre-magnetization implement with the Pulsating Vibration. RLC circuit wells will be shaped into a vibration wave, form pulsating high field strength.　　 Then, based on MCU control center designed to function with adaptive control system panels. System Controller software and hardware combining produce a pulsating magnetic field, magnetic suspension heavy concentration measurement, Synchronous detection, alarm and control functions work in the turn-magnet coils.　 Beside, this paper studies the special work environment of Pulse vibrates in demagnetize implement, the scene may potential interference and protection mechanisms of SCR, takes some work such as a hardware Software anti-interference measures, silicon stop absorbing, silicon design thermal protection measures. 　 Finally The overall device performance test results and magnetization, the testing showed that the reasonable timing mechanism for charge-discharge, two magnet coils heat adaptable, low consumption, adaptive control function of pre-magnetic magnetic implement.　 In this paper, the completion of the coal preparation industry electromagnetic system to promote the development of pre-magnetization implement, But as magnetized iron concentrator equipment to the pulp pre magnetization, magnetic boiler water, sewage treatment magnetization, Iron-iron recovery of the demagnetize process application. 　 　　　Key word: Demagnetize, Pulse, adaptive 　??矿产，是现代人类社会生存和发展不可缺少的物质基础。矿业，是国民
