A device for detecting material level of unloader in paste filling process

Abstract

The invention relates to a material level detection device for an unloader in a paste filling process, which includes a software control program, and is characterized in that it also includes a support frame, a spherical mounting plate, an angle limiter and an ultrasonic sensor, wherein the bottom of the support frame It is a conical cavity with a hemispherical cavity at the top; the spherical mounting plate is a spherical hollow body with a flattened top, and a through hole for ultrasonic transmission is opened in the center of the spherical mounting plate; the hemispherical cavity on the top of the support frame is provided with In the spherical mounting plate, an angle limiter is arranged symmetrically on the side of the through hole of the spherical mounting plate, and an ultrasonic sensor is arranged in the through hole of the spherical mounting plate. According to the characteristics of coal mine paste filling, the invention realizes the automatic detection of the material level of the unloader, saves labor costs, improves the continuity and reliability of material level detection, provides a guarantee for the continuous filling operation, and greatly avoids the slurry Spills and empty material pumping accidents occur.

Description

technical field [0001] The invention relates to a high-concentration material level detection device, in particular to a material level detection device for an unloader in a paste filling process for filling mines, which belongs to the technical field of paste filling and stirring slurry, and is suitable for mine filling and mining Feasibility testing of continuous stirring and continuous pumping. Background technique [0002] my country is the largest coal production and consumption country in the world. With the improvement of coal mining technology, in order to release the "three-down" coal pressing, the coal mine filling technology has been greatly developed. However, the mixing system and the pumping system need to work continuously during the paste filling process. As an intermediate link between the mixing system and the pumping system, the material level detection device and system of the unloader are particularly important. Material level detection technology is on...

AI Technical Summary

Problems solved by technology

[0006] 1. The operator in the centralized control room needs to observe the running status of the upper computer system and the video monitoring status of the unloader at the same time, and the continuity of the detection is not strong

[0007] 2. There is no obvious mark in the unloader, and the height of the material level cannot be accurately judged only through the video

[0008] 3. On-site monitoring probes are susceptible to interference such as dust, which can easily block the camera

[0009] 4. In order to ensure the quality of video signal transmission, it is necessary to lay optical fibers, which is expensive
