Coal fully automatic alloy industrial analyzer

The fully automatic industrial analyzer for coal is a new generation of high-precision instrument with dual control microcomputer, which is designed and improved based on traditional instruments This instrument has multiple testing methods for users to choose from, and the entire testing process meets the requirements of national standards. It can also be used for rapid testing, and the constant temperature and time can be set by oneself to shorten the total testing time

The industrial analysis of coal, also known as technical analysis and practical analysis, usually includes four items: moisture, ash content, volatile matter, and fixed carbon. Due to the pricing of coal based on its calorific value and the need for environmental protection, including calorific value and sulfur in industrial analysis is called generalized industrial analysis.

The fully automatic industrial analyzer for coal is a new generation of high-precision instrument with one machine dual control microcomputer, which is designed and improved based on traditional instruments. This instrument has multiple testing methods for users to choose from, and the entire testing process meets the requirements of national standards. It can also be used for rapid testing, and the constant temperature and time can be set by oneself to shorten the total testing time.

The following is the technical characteristics of the fully automatic industrial analyzer for coal to be shared with everyone:

1. Adopting a three temperature dual furnace integrated structure, the experimental environment and conditions of the simulated drying oven and muffle furnace can work in parallel, shortening the experimental time, and the constant temperature zones of the furnace do not interfere with each other, ensuring more accurate testing of moisture, ash content, and volatile matter on air dry basis.

2. Adopting a multi furnace structure with a constant temperature device, the three indicators of moisture, ash content, and volatile matter can be measured separately or in any combination.

3. Built in high-precision imported electronic balance, combined with automatic weighing mechanism, using thermogravimetric analysis method to automatically weigh, send, process data, calculate results, print and store reports, etc.

4. During the experiment, there is no need to remove or place crucible covers, send samples, or take samples to avoid the risk of high temperature radiation and burns.

5. Using a single testing host, accurate measurement of three industrial analysis indicators is achieved according to national standards, with high cost-effectiveness and complete functions.

6. Adopting imported integral heating furnace, with fast heating speed, energy saving, and short testing time. Equipped with a silent air pump, experiments can be conducted without the need for oxygen.

7. The circular well shaped high-temperature furnace has a uniform temperature distribution, and the fuzzy temperature control algorithm ensures control accuracy of ± 1 ℃.

8. The weighing and sample delivery mechanism with classic structural design adopts reasonable insulation methods to ensure a stable and interference free working environment for the built-in balance.

9. The control card adopts precision reference source, low drift high-precision operational amplifier, 12 bit A/D conversion chip, and has functions such as cold end compensation and over temperature software and hardware protection.

10. The PCI technology used is adapted to the new development of computer technology and can be combined with other instruments to form a comprehensive testing instrument, achieving multi control of one machine.

Run the testing program, enter the work testing menu, enter the relevant sample information, and the instrument automatically weighs the empty crucible. After the empty crucible is weighed, the system automatically opens the top cover, prompts to put in the sample, and then the system weighs the sample mass and starts heating. After heating up to around 145 ℃ and maintaining a constant temperature for 20 minutes, the crucible is weighed. When the weight of the crucible does not change beyond the system set value (default 0.0007 grams), the moisture analysis is completed, and the system reports the moisture measurement result. At this time, the system will automatically open the top cover, prompt to add the crucible cover, and the instrument will automatically weigh the weight of the crucible cover. Then, the system controls the high-temperature furnace to continue heating up, with a target temperature of 900 ℃. The high-temperature furnace temperature rises to 900 ℃, and after the specified time of constant temperature, the system will automatically open the top cover to start cooling down. When the temperature of the high-temperature furnace drops to the set value, the instrument will automatically weigh the mass of each crucible, and the system will report the volatile matter measurement.
