A sodium hydroxide standardization device directly connected to a translationally-moved pedestal in a sulfur determinator

Abstract

The invention discloses a sodium hydroxide standardization device directly connected to a translationally-moved pedestal in a sulfur determinator, and belongs to the field of analysis equipment of sulfur contents in soft coal combustible materials. The device comprises an L support disposed on a pedestal, a beaker translationally moving module, a measuring cylinder inclining module, a personal computer disposed on the L support, a high-definition camera disposed on the L support, beakers, a measuring cylinder and pH test paper. The personal computer is connected to the high-definition camera through a signal line. The beaker translationally moving module comprises a second lead screw support, a linear guideway, a first lead screw support, a Y-direction motor support, a sliding block, a ball screw, a rolling nut, a movable pedestal and a Y-direction motor. The movable pedestal is provided with the three beakers. The measuring cylinder inclining module comprises a first rotating-shaft support, a second rotating-shaft support, a U-shaped support, a rotating motor, a rotating shaft and a measuring cylinder base. The device is reasonable in structure, stable in movement and free of manual work, and achieves continuous standardization for solutions in the three beakers through translational motion of the pedestal and direct connection to the motor.

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 directly connected to a translational base in a sulfur meter. Background technique [0002] Measuring the sulfur content in coal has certain guiding significance for predicting environmental pollution and evaluating coal quality. The equipment for measuring the content of sulfur in combustible substances is called a sulfur tester. Among all kinds of sulfur testers, the high-temperature combustion and legal sulfur tester can get the test results in a short time. However, due to its many steps, it is difficult to realize the whole process of automatic measurement. One of the manual steps is the calibration of sodium hydroxide. In the prior art, the calibration of sodium hydroxide requires manual participation to complete. Manual participation in the calibration of sodium hy...
