Technical field
The present invention relates to a kind of cloud tin tabling automation process parameter and device intelligence monitoring and control method, belong to nonferrous metals ore Automation Technology for Beneficiation field.
Background technology
Shaking table is the main sorting equipment that heavy mineral is reclaimed in gravity treatment, and the operating parameters such as its feed ore concentration, volume, jig frequency, concentrate flushing water, the bed surface gradient are mainly to rely on operator to adopt artificial adjustment according to the Distribution Phenomena of ore properties and bed surface mine belt.Therefore, the gravity mill's cost of labor higher (accounting for ore dressing totle drilling cost 70%) take shaking table as main gravitational separation equipment, secondly adopts manual operation also cannot guarantee shaking table feed ore concentration and the accuracy to ore body accumulated amount, affects the sorting index of shaking table.
Former shaking table adopts the control of artificial visually examine's gate valve to feed to ore body accumulated amount, and feed ore concentration adopts artificial visually examine's gate valve to regulate ascending water size to be blended into ore deposit and regulates controlled concentration.
The driving of former shaking table adopts common Motor Drive, select suitable speed by adjusting decelerating through motor belt pulley, this selection is fixed, only has several jig frequencies to select simultaneously, change simultaneously jig frequency need first equipment is stopped change motor pulley could change, very inconvenient.
Mostly the size of former washings is to carry out regulating pondage by operating personnel by the size that regulates Water gate valve.
It is to regulate by a handle that the gradient of former lathe bed regulates, but can not see dynamically the effect that bed surface is adjusted simultaneously, and the efficiency simultaneously regulating is lower.
It is former that to connect ore deposit point be operator iron sheet is connect to mine mouth is placed into the corresponding position of table concentrate band and connects ore deposit according to visual, if situation above changes (as, concentration long-pending to ore body change), just needing operator to make in time corresponding adjustment, is not just the concentrate that needs but some waste products otherwise connect material that ore deposit point receives.
Therefore, carry out tabling automation process parameter and monitoring and control research, after research is applied to production, can significantly reduce the numerous shaking table operative employee number in tin ore dressing plant, reducing production costs; Guarantee that shaking table feed ore concentration, volume are stable, have important practical significance to improving sorting index.
Summary of the invention
