Problems solved by technology

[0005] However, for mineral materials with more soil and higher viscosity, the above-mentioned feeder not only cannot penetrate but also may make it more compact
At the same time, for large powder ore silos, the thick mineral layer of more than ten meters cannot be penetrated by the self-weight of this kind of feeder.

Embodiment 1

[0036]An automatic blockage removal device for blockage of the discharge port of a mine powder ore silo, the automatic blockage removal method adopted comprises the following steps: a, firstly carry out data on the material level of the ore bin, the operating frequency of the ore feeder and the amount of ore feed At the same time, establish a real-time curve of ore feeding to analyze and judge the state of ore loading, and set the lower limit of ore feeding. When the curve is abnormal, that is, when the ore feeding rate is lower than the normal ore feeding rate and less than the lower limit of the ore feeding rate, it can be inferred that the feeding of the powder ore bin is not smooth or the feeding port is about to be blocked; b. First, the feeding machine The working frequency of the machine is automatically adjusted to a certain high-frequency working area, that is, the ore feeding volume of the mining machine is controlled and increased. At this time, if the ore feeding vo...

Abstract

The invention provides a method and a device for automatically clearing blockage at discharge outlets of a fine ore bin of a mine. The method for automatically clearing the blockage at the discharge outlets of the fine ore bin of the mine is implemented by the device. The device comprises the fine ore bin and a PLC (programmable logic controller). The discharge outlets are formed in the lower side of the fine ore bin, a radar level gauge is arranged on the upper portion of the fine ore bin, vibrators are arranged on the side walls of the discharge outlets, ore feeders are arranged below the discharge outlets, a rubber belt conveyor for conveying materials is arranged below the ore feeders, an electronic belt scale is arranged above the rubber belt conveyor for conveying the materials, and the PLC is respectively connected with the radar level gauge, the vibrators, the ore feeders, the electronic belt scale and the rubber belt conveyor for conveying the materials. The method and the device have the obvious advantages that automatic operation can be implemented, blockage can be automatically and timely discovered, and a good blockage clearing effect can be realized.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a mining machine, in particular to a method and a device for automatically clearing the blockage of a discharge port of a mine powder ore silo. Background technique [0002] In my country's mining industry, especially gold, non-ferrous metal and bauxite mines, the ore is viscous or contains a lot of soil, which is easy to bond in the powder ore bin. Especially when the moisture content of the mineral is high or after mining and transportation in rainy days in the south, the looseness of the powder ore is very poor, which often causes the discharge port of the powder ore bin to be blocked. The blockage of the discharge port of the fine ore bin will cause discontinuous ore feeding in the grinding production process, or even stop production for blockage treatment, which seriously affects and restricts the production efficiency of the concentrator. The production energy consumption is high,...
