System for automatically controlling garbage feeding

Abstract

The invention discloses a system for automatically controlling garbage feeding. The system comprises a first radio frequency admittance material level switch, at least one second radio-frequency admittance material level switch and an ultrasonic sensor, wherein the first radio frequency admittance material level switch is provided with a low material level switch and a high material level switch;the low material level switch and the high material level switch are arranged on a drum feeding port material well wall from bottom to top; a flange sleeve is arranged at the mounting position of thefirst radio frequency admittance material level switch; a first radio frequency admittance material level meter is fixed on the flange sleeve and can be movably adjusted; the second radio-frequency admittance material level switch is arranged on the drum discharging port material well wall, and stops upper and lower feeding and sending an alarm of a high material level at the lower position underthe condition of high material level; and the ultrasonic sensor comprises a first ultrasonic sensor and a second ultrasonic sensor. According to the system, the automatic stable feeding function of aboiler feeding system can be realized, and material level detection, material breaking alarming, feeding port material level height limit alarming, automatic material supplementing, automatic feedingadjustment, automatic material breaking in an abnormal state and the like can be realized, so that the workload and pressure of operators are relieved, and the boiler combustion working condition is more stable.

Description

technical field [0001] The invention relates to a garbage feeding control system, in particular to an automatic garbage feeding control system. Background technique [0002] The circulating fluidized bed boiler feeds the material into the drum through the material well through the screw feeder, and then the drum rotates to throw the material into the boiler combustion chamber for combustion. The feed is in a sealed and negative pressure state. The existing feeding system is monitored by video visualization technology, and the operator manually intervenes in the feeding situation according to the video screen. Existing Problems: [0003] 1) The video screen is easily blurred by the negative pressure, dust and materials on site, which affects the operator's judgment of the site situation. [0004] 2) There is no accurate reference on the video screen, so it is impossible to accurately judge the amount of feed, which affects the judgment of feed. [0005] 3) The feeding met...

AI Technical Summary

Problems solved by technology

[0003] 1) The video screen is easily blurred by the negative pressure, dust and materials on site, which affects the operator's judgment on the site situation

[0004] 2) There is no accurate reference in the video screen, so it is impossible to accurately judge the amount of feed, which affects the judgment of feed

[0005] 3) The feeding method is too dependent on manual work and requires manual experience prediction, which is not conducive to the stable operation of production requirements
