Abstract

The invention discloses a full-automatic control system and method of a continuous production kiln. A pulse actuator, a proportional valve, an electromagnetic cut-off valve and an ignition detection controller are arranged for each spraying gun independently; a temperature detection device detects the current sintering condition of products and feeds back the sintering condition to a PLC control system; the PLC control system calculates out a control instruction according to the final sintering requirement of the products and the feedback current sintering condition, the pulse actuators, the proportional valves, the electromagnetic cut-off valves and the ignition detection controllers automatically control the spraying guns to act according to the instruction, and the products are subjected to sintering adjustment; due to arrangement of the PLC control system and the pulse actuators, the opening number of nozzles, the frequency of cycle operation of each nozzle within the certain time,the time of duration of each time of operation of each nozzle and the number of the spraying guns needed by a single cycle pulse are controlled automatically in real time according to the current sintering condition of the products, so that sintering on the products by the kiln is adjusted in real time, the obtained products meet the sintering requirement, and the consistent sintering quality ofthe products is ensured.

Description

technical field [0001] The invention relates to a control system, in particular to a fully automatic control system for a continuous production kiln and a control method thereof. Background technique [0002] In the existing continuous production kiln (such as roller kiln, shuttle kiln, tunnel kiln), the temperature in the kiln is monitored manually in real time, and the kiln is manually adjusted according to the firing requirements and actual firing conditions of the product. The furnace is controlled to adjust the appropriate temperature and firing time to fire the product. However, in order to meet the productivity, most of the kilns work continuously for 24 hours, so manual monitoring of the kiln is also required for 24 hours. Manual combustion cannot achieve complete combustion of gas, which consumes a lot of energy and causes serious environmental pollution; Monitoring is not only time-consuming and labor-intensive, but also has high labor costs, and there are bound t...
