Abstract

The invention discloses an automatic pulverized coal total moisture measuring device. The automatic pulverized coal total moisture measuring device comprises a turnover base assembly, a middle cavity assembly and an upper over assembly. The turnover base assembly comprises a base shell, a driving device and a turnover upper cover. The middle cavity assembly comprises a pressure and weighing sensor set, a sensor connecting plate, an infrared lamp tube supporting disc, a containing disc and a middle cavity support, a discharging port is formed in the side surface of the containing disc, and a plurality of infrared heating lamp tubes are arranged on the side wall of the infrared lamp tube supporting disc at equal intervals. The upper cover assembly comprises a spreading scraping claw, an upper cover, a temperature sensor, a feeding port and a driving motor. According to the automatic pulverized coal total moisture measuring device, the infrared heating mode is adopted to dry pulverized coal, penetrability is good, and drying efficiency is high; besides, the automatic discharging port is designed, the automation degree is high, and integration is easy.

Description

technical field [0001] The invention belongs to coal testing equipment, in particular to an automatic pulverized coal moisture measuring device. Background technique [0002] Before using coal, it is necessary to measure the total moisture of the coal and other indicators. Total moisture refers to the sum of external moisture and internal moisture. In order to avoid inaccurate measurement results due to the loss of coal powder moisture during the sample preparation process, the total moisture determination process must be closely integrated in the process of developing automated coal testing equipment. After level sample preparation. [0003] At present, with the continuous development of automation equipment, it is required that the pulverized coal moisture measurement equipment must have the characteristics of high heating efficiency and easy automation integration. The existing devices for coal moisture measurement generally have the disadvantages of low degree of autom...
