Real-time fixed-position material level detection system

Abstract

The invention discloses a real-time fixed-position material level detection system which is applicable to real-time fixed-position material level detection on powder and granular solid materials and comprises a detection plate, a transmission shaft, a support device, a driving device, a signal acquisition and display device and a sealing device. The support device comprises a bearing block, a rubber bearing, a self-aligning roller bearing, an isolating ring, a round nut, a lock washer and a bearing gland; the driving device comprises an encoder, a frequency modulator, a swinger, a mounting plate and a shaft end gland; the signal acquisition and display device comprises an angular displacement signal acquisition unit and a display; the sealing device comprises a labyrinth cover and a protective cover. The real-time fixed-position material level detection system has the advantages that the real-time fixed-position material level detection system is simple in structure, can reliably run and can be obliquely mounted, and accurate measurement results can be obtained; the real-time fixed-position material level detection system has certain antifreeze capacity and is particularly applicable to severe detection environments such as coal silos or discharge hoppers of dumpers, and the like.

Description

technical field [0001] The invention discloses a real-time fixed-point material level detection system, which is suitable for real-time fixed-point material level detection of powder and granular solid materials, and belongs to the field of material level detection. Background technique [0002] At present, the level detection devices for powder and granular solid materials can be divided into: contact type and non-contact type level gauge. Commonly used contact-type material level detection devices include: impedance type material level gauge, hammer type material level gauge and resistance-rotation type material level gauge, etc.; non-contact material level detection devices include: ultrasonic sensor, pressure sensor and laser sensor, etc. However, the above-mentioned material level gauge has certain defects for continuous feeding, high dust concentration, high moisture content of the material, and large particle size silos or hoppers, resulting in large errors in test re...
