灰份測(cè)量與跳汰生產(chǎn)過程控制
跳汰洗煤工藝自動(dòng)控制可以有效地穩(wěn)定精煤灰份，提高精煤產(chǎn)率，具有重大的經(jīng)濟(jì)效率?？v所周知，跳汰工藝是多變量相互影響的復(fù)雜過程，至今尚無有效的解決方案。然而其他條件一定時(shí)，通過調(diào)節(jié)排矸和中煤來實(shí)現(xiàn)一段和二段床層厚度的閉環(huán)控制，是一種行之有效的解決方法。此方法需要浮標(biāo)位移傳感器分別測(cè)量一、二段床層厚度，利用入洗原煤成分、風(fēng)水制度等條件與標(biāo)定的實(shí)驗(yàn)條件相同時(shí)，設(shè)定要求的精煤灰份所對(duì)應(yīng)的床層厚度，并對(duì)其進(jìn)行閉環(huán)控制。在執(zhí)行閉環(huán)控制程序過程中，通過調(diào)節(jié)排矸(和中煤)的數(shù)量，來維持床層厚度為設(shè)定值;而當(dāng)原煤煤質(zhì)、給煤量、風(fēng)水等有變化時(shí)，跳汰司機(jī)可根據(jù)經(jīng)驗(yàn)或由標(biāo)定曲線來改變?cè)O(shè)定值的大小。
濃縮加藥自動(dòng)控制系統(tǒng)
選煤廠采用成套的自動(dòng)加藥系統(tǒng)實(shí)現(xiàn)煤泥水濃縮系統(tǒng)自動(dòng)加藥。加藥系統(tǒng)的檢測(cè)儀表同時(shí)進(jìn)入選煤廠集控系統(tǒng)，實(shí)現(xiàn)濃縮系統(tǒng)工藝參數(shù)的實(shí)時(shí)檢測(cè)和統(tǒng)計(jì)、管理。that is, before and after 1978 as the dividing line. The main characteristics of these two stages can be summarized as follows:
1. The closure of China before 1978 made machinery manufacturers know little about the level of the same industry in the world. At that time, when the technology of single board computer and PLC developed in two tracks, China's national industry almost ignored the development of PLC and emphasized the scattered application of single board computer. The impact on China's machinery manufacturing industry at that time was obvious. In terms of automation level, analog electronic circuit and relay control are the dominant factors in mechanical automation. However, computer control based on single board computer is still rare.
2. After 1978
China's opening up has naturally brought vitality to the national machinery manufacturing industry. Looking at the outside world, the Chinese people are acutely aware of the gap between China's machinery manufacturing industry and Europe and the United States. Therefore, the first problem faced by the machinery manufacturing industry is the change and renewal of concepts. The development of machinery manufacturing automation can be summarized by the following characteristics:
(L) the computer control idea represented by single board computer has become the mainstream of high-grade automation in the early stage of China's opening up. During this period, the cooperation between factories and colleges played a positive role.
