Problems solved by technology

When the feeding amount of the pelletizing disc changes, it is necessary to manually adjust the speed, water supply, feeding amount, etc., which brings a lot of complicated workload to the operator.
[0004] In addition, the speed signals collected on-site, including the speed of the pelletizing disk and the speed of the scraper, are voltage frequency signals, which are often subject to on-site electromagnetic interference and cause signal jitter and distortion when transmitted to the control room

Abstract

A pelletizing disc control system and method belong to the technical field of automation of the metallurgical industry. The pelletizing disc control system comprises a pelletizing disc controller, a feed silo meter, a feeding belt batching scale, a water supply flowmeter, a control valve, a pelletizing disc speed sensor and a scraper speed sensor, wherein the sensors acquire data of feed silo material level L, pelletizing disc feed quantity W, supply pipe water addition F, control valve opening degree V, pelletizing disc rotational speed S and scraper rotational speed S1 and send the acquired data to an upper computer and the pelletizing disc controller; the upper computer performs linkage on L and feeding belt speed; the pelletizing disc controller performs linkage on F and W; and an operator can adjust S, S1 and F according to the pelletizing quality and displayed values. As operation of pelletizing discs are centralized on site, the pelletizing quality can be improved more visually and efficiently, and the production efficiency is improved; one person can operate multiple pelletizing discs to pelletize; and frequency signals susceptible to electromagnetic interference are converted into standard current signals which are then transmitted to the upper computer, so that the signal truth and accuracy are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of metallurgical industry automation, and in particular relates to a control system and method for a pelletizing disc. Background technique [0002] In the production process of the disc pelletizer, there are generally problems of low output per table, poor pellet quality and high powder content. [0003] Pelletizing is an important part of pellet production, but because there are many factors that affect the pelletizing effect, such as incoming material composition, particle size, feed size, water addition, pelletizing disk speed, angle, etc., these factors are interrelated. At present, There is no practical mathematical model, and it is difficult to realize automatic control. Generally, the pelletizing factory sets up post workers for each disc pelletizing machine to observe the particle size, quality, powder content, etc. of the pellets, and inform the control room to adjust the speed and water supply th...
