Description

Technical Field

[0001] The invention belongs to the technical field of detection instrument installation, and in particular relates to an integrated level measurement device suitable for a mine bin. Background Art

[0002] At the mine construction site, in order to better utilize space, improve storage efficiency, and save investment costs, the middle ore bin is designed to be hemispherical. Because the feeding belt conveyor on the upper part of the ore bin has only one unloading point, its material storage shape is conical. Multiple vibrating ore dischargers are arranged under the center of the cone to unload 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-feeding machine, and the vibrating ore-feeding machine needs to be turned on according to the material situation directly above the ore-feeding machine (if there is no material directly above, the ore-feeding machine will be turned on and will be empty, affecting the subsequent process flow and damaging the equipment). The level measurement of the hemispherical ore bin is limited by the on-site installation position, and it is impossible to install a level meter directly above each vibrating ore-feeding machine. Due to the information feedback delay of the 3D level scanning technology, it cannot meet the on-site control needs.

[0004] The existing technology mainly detects the material level by installing a radar level meter or 3D level scanning at the material drop point of the hemispherical ore bin belt. The existing installation method is to install only one ordinary radar level meter, which can only monitor the material level at one position and can only be used to guide the feeding belt at the front end. It cannot determine the material level above the vibrating feeder at the bottom of the ore bin, thereby guiding the operation of the vibrating ore discharger.

[0005] However, the 3D level scanning solution has a long scanning cycle (minutes) and a longer time period for processing feedback, which results in a longer time and cannot meet the requirements of real-time guidance of the vibration ore discharger. The 3D level scanning solution is more suitable for inventory scenarios, and the use of 3D level scanning will significantly increase investment costs, so it is necessary to make improvements. Summary of the invention

[0006] In order to solve the above problems in the prior art, the present invention provides an integrated level measurement device suitable for a mine bin, which solves the problem that single-point installation can only detect single points and the problem of high delay during 3D level scanning.

[0007] To achieve the above object, the present invention adopts the following technical solutions:
