Stock bin with material level measuring device

Abstract

The invention discloses a stock bin with a material level measuring device. The stock bin comprises a bin body, a measuring probe and a measuring transmitter, wherein the top and the side wall of the bin body are provided with installing grooves, the measuring probe is embedded in the installing grooves, the measuring probe comprises a protective shell, a central layer and a shielding layer, the central layer and the shielding layer are wrapped in the protective shell, the measurement transmitter is connected to the top of the bin body through a flange, the central layer is connected to the input end of the measurement transmitter, the shielding layer is connected to the output end of the measurement transmitter, and the grounding end of the measurement transmitter communicates with the bin body. The integrated material storage and material level measurement stock bin can be used for directly measuring solid materials in the bin body in a contact mode, is not affected by hanging materials on the probe and the wall face of the bin body and temperature changes, and can avoid the conditions of probe deviation, damage, bending and the like of a common contact type material level meter, the reliability and accuracy of solid material measurement are improved, and the instrument maintenance cost is reduced.

Description

technical field [0001] The invention relates to a silo with a material level measuring device, in particular to a material storage device integrated with a radio frequency admittance level gauge and a storage silo body, which belongs to the field of material measurement. Background technique [0002] The existing solid particle material measurement methods are generally contact level gauges and non-contact level gauges. Non-contact level gauges, such as radar level gauges, measure the height of the material level by emitting microwaves and receiving microwaves, which is prone to echo interference. Situation; Contact level gauges such as static capacitance level gauges generally calculate the height of the material level by inserting the probe rod or the weight rope into the solid material to measure the capacitance value between the probe rod and the wall. Due to the flow and frequent displacement of the material surface , so that the probe rod or rope often bends or deviate...
