On-line detection device for water content of machine-made sand

Abstract

The invention provides an on-line detection device for the water content of machine-made sand. The on-line detection device comprises a shell, a support, a sampling device, a drying device, a weighingdevice, a turnover device, a control device and a man-machine interactive device, wherein the support is arranged in the shell; the man-machine interactive device is arranged on the outer side of theshell; the sampling device is arranged on the inner side of the shell so as to obtain a machine-made sand sample and input the machine-made sand sample into the drying device; the drying device is arranged below the sampling device so as to receive and dry the machine-made sand sample; the weighing device is connected with the drying device so as to obtain the mass of the machine-made sand samplebefore being dried and the mass of the machine-made sand sample after being dried; the turnover device is arranged between the support and the drying device, so that after the machine-made sand sample is dried, the drying device is overturned downwards and restored; the control device communicates with the sampling device, the drying device, the weighing device, the turnover device and the man-machine interactive device. The water content of the machine-made sand is automatically detected and monitored in real time, operation is convenient and fast, the work efficiency is improved, and miscalculation is prevented.

Description

technical field [0001] The invention relates to an online detection device for the moisture content of machine-made sand. Background technique [0002] Among the raw material components required for dry-mixed mortar, dry sand accounts for the largest proportion. Generally, the dry sand in dry-mixed mortar mainly uses natural river sand, but at present, the mining of natural river sand has been completely prohibited in various regions, resulting in natural river sand The increasing shortage has been unable to fully meet the needs of construction projects, so it is imperative to use machine-made sand to replace natural sand. [0003] The water content of machine-made sand needs to be controlled during the production process. At present, the equipment used by domestic machine-made sand manufacturers does not have an online detection device for water content of machine-made sand. The sampling of machine-made sand and the detection of water content are completely done manually. S...
