Problems solved by technology

[0003] Domestic kiln process control system, the configuration of electrical control devices is too simple, the production process largely depends on manual adjustment, and operators have different adjustment methods according to their personal understanding of equipment production, resulting in inconsistent product quality Similarly, the difference caused by human beings cannot be determined, which will cause unpredictable losses to the quality of the produced products and have great hidden dangers to the production.

Embodiment Construction

[0040] In order to make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following describes the technical solutions in the embodiments of the present invention clearly and completely in conjunction with the drawings in the embodiments of the present invention:

[0041] Such as Figure 1-6 Shown: Rotary sleeve shaft furnace process control system, mainly including: burning chamber material level control unit, target value 2.3±0.5m, such as figure 1 , Use the radar level meter to detect the material surface height of the shaft furnace baking chamber, and the signal level detection transmitter 5 is connected to the PLC controller 4.

[0042] PLC controller 4 uses PID controller for closed-loop control such as figure 2 As shown, according to the set value of the material level, the material level of the baking chamber is controlled at a constant position. The PLC controller 4 outputs the signal to the frequency converter 7, a...

Abstract

The present invention discloses a control system of a turn-barrel type shaft furnace. The control system comprises a tail gas voltage stability control unit, a combustor constant temperature control unit, a constant furnace pressure control unit and a roasting chamber charge level control unit. By making the best of real-time data tested and collected on the spot, roasting chamber charge level control, constant furnace pressure control, tail gas voltage stability control, combustor constant temperature control and inside-furnace charge level control of the shaft furnace equipment are realized, thus to guarantee the roasting quality of pellets. The above control concept can be generalized into similar furnace products, and is economical, practical and widely applicable.

Description

Technical field [0001] The invention relates to a rotary sleeve shaft furnace process control system. Involving patent classification number F27 furnace; kiln; baking furnace; distillation furnace F27D more than one kind of furnace, kiln, baking furnace or distillation furnace parts or accessories F27D3 / 00 charging; unloading; charge control. Background technique [0002] At present, the domestic ferroalloy pellet shaft furnace generally uses the shaft furnace for firing iron ore pellets. After simple transformation, increasing the calcination temperature and other methods to achieve ferroalloy pellet production, the technical level is relatively low, the control system is single, the technology is too simple, and the product quality Poor, unable to meet the requirements of modern production. Because of its backward technology, high energy consumption, serious environmental pollution, harsh labor environment, high labor intensity, and low production efficiency, it cannot compete...
