Embodiment Construction

[0018] see figure 1 and figure 2 , a sintering automatic distributing method, the control components mainly include: nine-roll distributing device 7, VVVF frequency converter, round roller motor, micro-motion motor, PLC programmable controller, PID proportional, integral, differential controller, computer and radar Material level gauge 11.

[0019] The automatic material distributing device of the sintering machine is composed of radar level gauge 11, the model of radar level gauge 11 is VEGAPULS68, material distributing equipment and control system. The structure of the device is as follows: figure 1 As shown; the control system is divided into 6 speed automatic control systems of round roller feeders and auxiliary gate opening automatic control systems,

[0020] Since the inclination angle of the sintered mixture accumulation is fixed, the measured material height of the mixture accumulation shows a linear change trend. The changing trend of the amount of mixed material ...

Abstract

The invention includes radar level-sensing device, feeding equipment and control system. The control system includes system for automatic controlling speed of feeding equipment of round roller, and system for automatic controlling extent of opening of assistant gate. The radar level-sensing device is installed in front of the feeding equipment. Measuring direction of the radar level-sensing device is faced to the feed opening of feeding equipment with nine rollers. When height of materiel measured by radar is in trend of linear variation, computer is connected to the radar level-sensing device directly. Using PACTware software to setup control value, the invention carried out real time control through automatic feeding method including longitudinal and lateral feeding methods. Features are: in high real-time, little investment about 1 / 10 investment of current automatic feeding equipment, and good reliability.

Description

【Technical field】 [0001] The present invention relates to an automatic sintering distribution method, in particular to an automatic sintering distribution method for real-time control of longitudinal distribution of sintering machine and lateral distribution of sintering machine which is jointly implemented by a radar level gauge, distribution equipment and a control system. 【Background technique】 [0002] Explanation of terms: VVVF is frequency converter; LC is programmable controller; PID is proportional, integral and differential controller; CRT is control panel. [0003] At present, domestic sintering machines are clothed by manual, semi-automatic or automatic methods. Manual distributing is to observe the material layer thickness on the sintering machine trolley by the on-site operator. According to the change of material layer thickness, generally the change is more than 50mm before the operator can perceive and adjust the distributing equipment; semi-automatic distrib...
