On-site sampling and calibrating device and method for powder and particle materials

Abstract

The invention belongs to calibration of moisture measurement of powder and particle materials, namely, a standard method (national metrological verification regulations) is adopted to measure a collected sample to determine the moisture content of the powder and particle materials, and particularly relates to a device and a method for sampling and calibrating the powder materials, which are mounted on a production site. The problems that the labor cost is high, the working efficiency is low, calibration is not timely, and the measurement precision cannot be guaranteed can be solved. The device comprises a material taking unit, a transferring unit and a weighing and heating unit. The material taking unit comprises a semicircular pipe material taking device with a sharp front end and a lever structure, a front end feeding port of the semicircular pipe material taking device faces a material conveying belt, the transferring unit comprises a disc-shaped rotary positioning device and a conveying belt, ten (multiple) sealing tanks are placed on the disc-shaped rotary positioning device, and temperature sensors and heating rods are arranged in the sealing tanks. A steel wire mesh is arranged on the lower middle portion of the sealing tank, a movable plate is arranged at the bottom, and the weighing heating unit comprises two balances and a drying bin.

Description

technical field [0001] The invention belongs to the calibration of the moisture measurement of powder and granular materials, that is, a standard method (national metrological verification regulation) is used to measure the collected samples to determine the moisture content of the powdered and granular materials, in particular to a method installed on a production site to sample powder materials Apparatus and method for calibration. Background technique [0002] It is well known that the moisture content of the sintering mixture is an important factor affecting the efficiency of sintering production. Therefore, the moisture measurement device for powder and granular materials applied to the production site needs to be calibrated according to regulations; at present, sampling, drying and weighing are performed manually, and then the moisture content of the material is calculated using the standard calculation formula; this way This results in high labor costs, low work effi...
