Continuous ash analyzer

Continuous ash analyzer
HF-2A typeContinuous ash analyzerIt is a specialized device for determining the ash content of coal and other combustible substancesBe prepared; Place the test sample on the conveyor chain, enter the high-temperature zone with the chain for combustion, and then be sent out of the furnace.Due to the slow entry of the sample into the high-temperature zone, detonation of the sample was avoided. Additionally, the speed of the conveyor chainStepless adjustable, the ashing time can be changed according to the requirements of the sample. It has the ability to measure compared to a regular muffle furnaceThe advantages of fast speed, stable and reliable performance, high degree of automation, and high measurement efficiency are that the efficiency is superior to that of MaFu
4-5 times the size of the furnace. Widely used in laboratory departments of industries such as coal, electricity, steel, and chemical, mainlyUsed to determine the ash content in coal, coke, and other substances.
Main technical indicators:
Sample size: 0.5 ± 0.01g, accurate to 0.0002g
Test time: adjustable from 15 to 50 minutes
Furnace length: 730mm
Constant temperature strip length: ≮ 150mm at 815 ℃, temperature difference ≯ ± 10 ℃
Maximum furnace temperature: 900 ℃
Heating time: (from room temperature to 815 ℃) 45 minutes
Power supply: AC220V ± 10%, 50Hz
Maximum power: 4KW
Chain running speed: 15-70mm/min
Measurement accuracy: superior to the GB212-2001 standard

Usage and maintenance:
1. The instrument should be placed horizontally on the workbench, with the furnace mouth avoiding the air inlet to ensure natural ventilation and combustion assistance.
2. Connect the power, turn on the running switch, and check and adjust the operation of the transmission machine.
(1) The direction of chain operation should be from the higher end of the furnace to the lower end；
(2) The chain should run smoothly without any deviation, otherwise it can be corrected by adjusting the adjusting pin of the sprocket；
(3) The tightness of the chain must be adjusted before the temperature rises, which can be done through the sprocket adjusting screw. When adjustingThe chain should be slightly loose, neither too tight nor too loose.
3. Adjust the running speed of the conveyor chain as needed.
4. Regularly check the working conditions of each part and maintain them carefully. The supporting wheels and gear reducers should be regularly checkedLubrication should be added, and the furnace should be cleaned before each test to prevent debris from affecting the test results.
