Introduction: CZ-MF-400 coal intelligent fast ashing furnace is a new generation intelligent energy-saving integrated muffle furnace independently developed by our company. It can automatically complete the determination of slow ash, fast ash, bond index and volatiles in strict accordance with the relevant provisions of GB/T212-2008. It can also be applied to a series of heating, burning or drying treatments such as fixed-point constant temperature and timed heating of the tested objects in other industries. The instrument has the characteristics of high measurement control precision, high efficiency (energy saving), stable and reliable performance, convenient operation and high degree of automation. Therefore, it is widely used in coal, coking, electric power, metallurgy, petroleum, chemical and other industries and scientific research departments. Features: In addition to the test procedures for industrial analysis of slow ash, fast ash, volatilization, and bonding, which are provided by traditional controllers, a powerful self-selection program has been added. The optional program can set up 100 independent programs, and each In a separate program, 100 different constant temperature points and constant temperature time can be set. Powerful, compatible, and able to meet the needs of multiple industries. In the volatile experiment, the effect of restoring 900±10°C in 3 minutes is excellent. The authenticity of the recovery temperature and the accuracy of the experimental result data are the characteristics of the temperature control effect of the product. The high-end controller ARM9 is used as the control core, and the single-chip microcomputer is the auxiliary acquisition module. The PID algorithm and the fuzzy control technology are used to automatically correct the measured temperature. The automatic phase shift triggers the thyristor conduction angle and controls the heating power. The operation platform adopts two methods of “inductive touch” and “button”, which can be used alternately and independently, which makes the experimental operation more reliable, flexible and convenient. The display platform adopts a large-size color liquid crystal touch screen display, and the display information is very rich, intuitive and clear. Support the inspection of documents or documents, and view the national standard requirements, experimental methods and experimental procedures of coal test methods at any time after starting up. Highly integrated, fast data acquisition and high precision. It has the function of prompting fault phenomenon, fault cause and troubleshooting method. With a variety of circuit protection features. The furnace body is made of imported materials, and the temperature field is uniform and durable. The overall structure of the equipment adopts an integrated structure, which is beautiful and easy to maintain. Technical Parameters: Power supply voltage: AC220±10%V, 50Hz Temperature range: ambient temperature ~ 1000 ° C, temperature error ≤ ± 1 ° C Temperature control range: 300 ~ 950 ° C, temperature control error ≤ ± 2 ° C Instrument power consumption: <10W Load power: ≤3.5KW (zui large available 4.5KW) Control period: ≤0.5 seconds Sampling period: 250 milliseconds / time Temperature control mode: PID algorithm and fuzzy control technology are used to automatically correct the measured temperature, and the automatic phase shift triggers the conduction angle of the thyristor to control the heating power.
