Description

Technical Field

[0001] The utility model belongs to the technical field of installation of detection instruments, and specifically relates to an integrated device for level measurement. Background Art

[0002] At the construction site of a mine, in order to make better use of space, improve storage efficiency and save investment costs at the same time, the intermediate ore bin is designed as a hemispherical shape. Since there is only one discharge point for the feeding belt conveyor at the upper part of the ore bin and the shape of its material storage is conical, multiple vibrating ore discharge machines are arranged below the cone center to discharge the material onto the transfer belt conveyor for subsequent material processing.

[0003] The on-site transfer belt conveyor needs to be interlocked with the vibrating ore discharge machine, and the vibrating ore discharge machine needs to be started according to the material condition directly above the ore discharge machine (if there is no material directly above and the ore discharge machine is started, it will cause no-load operation, affecting the subsequent technological process and damaging the equipment). The level measurement of the hemispherical ore bin is restricted by the on-site installation position, and it is impossible to install a level gauge directly above each vibrating ore discharge machine. Due to the information feedback delay of the 3D level scanning technology, it cannot meet the on-site control requirements.

[0004] The existing technology mainly conducts level detection by installing a radar level gauge or 3D level scanning at the position of the belt falling point of the hemispherical ore bin. The existing installation method is to install only one ordinary radar level gauge, which can only fixedly monitor the level at one position and can only be used to guide the feeding of the front-end feeding belt, and cannot determine the level situation above the vibrating feeder at the lower part of the ore bin, so as to guide the operation of the vibrating ore discharge machine.

[0005] When adopting the 3D level scanning scheme, due to its long scanning period (in minutes) and the increase in the time period for processing and feedback, the time is prolonged, and it cannot meet the requirement of guiding the operation of the vibrating ore discharge machine in real time. The 3D level scanning scheme is more suitable for the inventory-taking scenario, and using 3D level scanning will greatly increase the investment cost. Therefore, it is necessary to make improvements. Summary of the Utility Model

[0006] In order to solve the above problems of the existing technology, the utility model provides an integrated device for level measurement, which solves the problems of single-point detection for single-point installation and high delay in 3D level scanning.
