The invention discloses a worm-drive double-rotation sodium hydroxide calibration device in a sulfur determinator, and belongs to the field of analytical equipment of the sulfur content in bituminous coal combustible matter. The worm-drive double-rotation sodium hydroxide calibration device in the sulfur determinator comprises a beaker rotation module, an operation end rotation module and a measuring cylinder worm-drive tilting module; the beaker rotation module comprises a U-shaped frame, a first motor frame, a first motor and a rotary table; four beakers are installed on the rotary table, and each beaker contains a sulfuric acid solution and PH test paper; the operation end rotation module comprises a cross beam, a second motor frame, a PC machine, a second motor, a camera frame, a rotating plate and a camera; the measuring cylinder worm-drive tilting module comprises a first L frame, a second L frame, a worm, a third motor frame, a third motor, a worm gear and a measuring cylinder base; a measuring cylinder is installed on the measuring cylinder base, and a sodium hydroxide solution is contained in the measuring cylinder. The worm-drive double-rotation sodium hydroxide calibration device in the sulfur determinator is compact in structure, free of artificial participation and capable of continuously calibrating the solutions in the multiple beakers through double rotation of a base and the operation end and worm drive.
Description
technical field [0001] The invention mainly relates to the field of analysis equipment for sulfur content in bituminous coal combustible substances, in particular to a sodium hydroxide calibration device with spiral transmission and double rotation in a sulfur meter. Background technique [0002] Measuring the sulfur content in coal has certain guiding value for predicting environmental pollution and evaluating coal quality. In the prior art, a sulfur-determining meter is generally used as a commonly used measuring device. Among various sulfur-determining meters, the sulfur-determining meter made by high-temperature combustion neutralization method has many advantages, and the test result can be obtained in a short time. However, the high-temperature combustion neutralization method has many steps, and it is difficult to realize the whole process of automatic measurement. For example, sodium hydroxide solution is used to calibrate the sulfuric acid solution generated by com...
