The invention discloses a gear-driven rotating operation-terminal sodium hydroxide calibration device of a sulphur determination device, and belongs to the field of soft coal combustible material sulfur content analysis equipment. The gear-driven rotating operation-terminal sodium hydroxide calibration device comprises four beakers arranged on a beaker disk in an axisymmetrical manner, a pH teat paper, an operation terminal rotating module, and a gear-driven inclining module; the operation terminal rotating module comprises a U-shaped support, a rotating motor frame, a PC, a rotating motor, a rotating shaft, a camera support, a suspending plate, and a camera; the gear-driven inclining module is arranged on the suspending plate; the gear-driven inclining module comprises a first L support, a second L support, an inclining motor support, an inclining motor, a driving shaft, a driven shaft, a driving wheel, and a driven wheel; the end part of the driven shaft is provided with a measuring cylinder pedestal, a measuring cylinder is arranged on the measuring cylinder pedestal, and the measuring cylinder is filled with a sodium hydroxide solution. The gear-driven rotating operation-terminal sodium hydroxide calibration device is compact in structure, is used for continuous sodium hydroxide calibration of solution in a plurality of beakers via operation terminal rotating and gear driving; and no manual operation is needed.
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 at the gear transmission rotating operation end of a sulfur meter. Background technique [0002] It is of great value to measure the content of sulfur in the combustibles of bituminous coal. In the prior art, in order to accurately and quickly measure the sulfur content in the combustibles, a sulfur meter is generally used. Among all kinds of sulfur determination instruments, the high temperature combustion neutralization legal sulfur instrument can get the test results in a short time and is very popular. However, due to the many steps in the high-temperature combustion neutralization method, it is difficult to realize the whole process of automatic measurement. For example, the high-temperature combustion neutralization method needs to use sodium hydroxide solution to cal...
