Description
Technical field
The utility model relates to the detecting instrument of Chemical Manufacture aspect, particularly a kind of metal furnace furnace temperature thermostatic control device.
Background technology
The metal furnace is widely applied in the control of all types of industries such as metallurgy, chemical industry, machinery, and occupies very important status in national economy along with the development of science and technology and the raising of commercial production levels.
Along with the development of modern times to the Control for Kiln Temperature technology, metal smelt enterprise is more and more higher to the requirement of product quality, if the excess Temperature in the boiler, to have so the danger of blast, domestic such production accident also is recurrent, and this will bring the loss that can't estimate to production and daily life.If temperature is excessively low, just do not reach the technological requirement of product at all.So, very important to the temperature control of metal furnace, also be very necessary.For example whether the quality of molten iron meets the demands, and key is prediction and the controlling unit of furnace temperature, and the Control for Kiln Temperature of ironmaking enterprise now mainly relies on historical measurement data, realize according to the dispatcher, the performance response speed is slow, and error range is large, is not suitable for the development of enterprise automation.The smelting furnace temperature of Coke Industry is controlled still immature control method automatically, mainly is to adopt old mode of operation, is measured once every 4 hours by the thermometric workman, carries out adjustment one time to operating room again.Manual measurement is subjected to the impact of thermometric time, point for measuring temperature and the uncertain factors such as operator's qualification and outside natural environment, and its measurement result and actual value error are larger.In existing temperature Control of Electric Heater scheme, fuzzy control is used at most, and is also the most representative, can only adapt to general temperature system observing and controlling, is difficult to control complicated large time delay time varying temperature system.Therefore real-time data acquisition is requisite part in the industrial control system, is to carry out Industrial Analysis, the foundation of industrial treatment and Industry Control.
Summary of the invention
The problem that exists in order to solve background technology, the technical scheme that adopts is as follows: a kind of metal furnace furnace temperature thermostatic control device, by metal furnace module, the thermostatic control module, computing machine module forms, it is characterized in that: described metal furnace module is by body of heater, the oxygen rifle, heating electrode, convective tube, agitation fan, the combustor system forms, described thermostatic control module is by thermocouple, converter, single-chip microcomputer, temperature control circuit forms, described computing machine module is by USB interface, the computing machine forms, and connects by the thermostatic control module between metal furnace module and the computing machine module.
Described body of heater is comprised of upper cover, stove stage casing and lower shell.
