Material level measuring device

Abstract

The invention discloses a material level measuring device which is used for measuring the material level height of a solid stock bin. The material level measuring device comprises a weight, a PLC (Programmable Logic Controller), a lifting mechanism which is used for driving the weight to lift, a displacement measuring device used for measuring the displacement of the weight and a sensing device used for sensing the weight change of the weight, wherein the lifting mechanism, the displacement measuring device and the sensing device are respectively connected with the PLC electrically. The device also comprises an over protection device which is used for performing limit protection in the lifting process of the weight, and is electrically connected with the PLC. The device is suitable for the material level measurement of the solid stock bin with bad environment and more dust; the over protection device is arranged for performing limit protection when the weight is lifted; the device is not easily influenced by dust in the measuring process, and the measurement result is accurate; the device has the advantages that the cost is low, the antijamming capability is strong, the structure is simple, the operation is convenient, and safety and reliability are high.

Description

technical field [0001] The invention relates to the technical field of level measurement, in particular to a level measurement device for level measurement of a solid silo. Background technique [0002] At present, there are a variety of level measuring instruments on the market, and the applicable environments are also different due to the different silo devices. [0003] The solid silo is a container for storing solid loose materials, but when solid materials such as lime powder, coal, grain, etc. enter the silo, a large amount of dust will be generated, and laser measurement or ultrasonic measurement will be interfered by other factors such as dust, concave-convex surface, etc., thus It will affect the accuracy of the measurement results, and when the dust in the silo is serious, it will cause the instrument to fail. Although the above-mentioned problems can be overcome by using a 3D level scanner, its cost is too high. [0004] Therefore, in the solid silo, a heavy ham...

AI Technical Summary

Problems solved by technology

In the process of measuring work, due to the influence of dust, some parts in the measuring device may break down. If the heavy hammer cannot stop running due to the above-mentioned failure during the rising process, the heavy hammer will keep rising until it is broken. The entire level measuring device, which has adverse consequences for the measuring work
