The invention discloses an automatic adjusting method, wherein the automatic adjusting method is capable of achieving automatic adjusting of an adjusting device of an annular sleeve kiln according to practical situation by the practical controlling situation obtained by a detecting unit and calculated and controlled by a programmable logic controlling (PLC) system. The automatic controlling method of annular sleeve kiln device mainly comprises steps as below: an adjusting device need to set up is selected through a human-machine interface and a standard value Y is set up, a main value K1, and a differential value K2 of the adjusting device; The PLC controlling system receives the setting up values transmitted from an upper machine, calculates the upper limit and the lower limit of a controlling range, and transmits the controlling range to the upper machine and displays the controlling range. The PLC controlling system monitors detection value Ys of each detecting unit in real time. When Ys of each detecting unit is not in the controlling range, the system transmits adjusting commands to turn up or turn down the adjusting device capable of controlling the detection values. The PLC controlling system monitors feedback values of the adjusting device, and the system is automatically locked and alarms when the feedback value of the adjusting device exceeds the upper limit or the lower limit of the feedback value.
Description
technical field [0001] The invention belongs to the technical field of automatic control, and in particular relates to a method for automatically controlling various adjustment devices on an annular sleeve kiln. Background technique [0002] During the production process of the annular sleeve kiln process, it is necessary to adjust the process parameters from time to time as the production changes. For example, adjust the pipeline pressure or flow through the regulating valve; adjust the speed of the high-temperature fan through the hydraulic coupling, thereby adjusting the negative pressure in the kiln. There are usually dozens of adjustment points and dozens of sets of adjustment devices in an annular sleeve kiln. At present, most of them are completely operated by operators one by one, which is not only time-consuming and laborious, but also difficult to adjust in place in time and accurately, which seriously affects production efficiency and product quality.
