Device for eliminating blocking stocks from reinforced concrete ore bin and using method thereof

Abstract

The invention discloses a device for eliminating blocking stocks from a reinforced concrete ore bin and a using method thereof. Multi-layer pneumatic flow-aiding air pipes (17) are additionally arranged on the bin wall of an ore bin cone (2), pneumatic flow-aiding nozzles (15) with different ejection directions are arranged on the pneumatic flow-aiding air pipe (17), and the pneumatic flow-aidingair pipe (17) is connected with an air compressor by a pipeline; carbon-manganese plates or steel plates (3) are paved at four pyramid angles in a rectangular funnel bin of the reinforced concrete orebin, and a pneumatic vibration hammer (11) is additionally arranged at the rear part of the carbon-manganese plate or the steel plate (3); and the pneumatic vibration hammer (11) is connected with apulse electromagnetic valve set, a pneumatic triplet piece and the air compressor in sequence by pipelines. In the using method, all groups of nozzles are controlled to ventilate according to the ejection sequence from the bottom layer to the top layer, the interval time can be adjusted within 1-9 seconds, the flow-aiding air pressure is set between 0.4MPa and 0.8MPa, and the air pressure of the pneumatic vibration hammer is controlled between 0.5MPa and 0.7MPa. The invention can eliminate the blocking stocks in the ore thoroughly, ensure smooth feeding in ore dressing production, simple structure, reliable working and convenient operation, and improve the effective volume utilization ratio of the ore bin by 1 / 4-1 / 3.

Description

technical field [0001] The present invention relates to an anti-blocking and clearing device and method for ore storage bins, in particular to a device for removing blocked shed materials in reinforced concrete ore bins and a method for using the same, which can be used for clearing ore storage bins in various mine dressing plants. Plug anti-blocking. Background technique [0002] At present, the ore dressing plants of various mines are equipped with ore storage bins, which are used to adjust the production process, allocate ore selection paths, adjust the amount of ore input, and balance the ore processing process. Most of the ore bins adopt reinforced concrete structure and rectangular funnel bins. When the ore enters the silo, the friction between the ore and the silo wall increases due to different physical factors such as ore moisture content, lumpiness, and surface properties, so the ore cannot slip out of the silo under its own gravity, causing the material to stick ...

AI Technical Summary

Problems solved by technology

Due to the high moisture content of the material, the cohesive force increases to form an arched shed material. There is a large amount of material stored around the warehouse that cannot be discharged out of the warehouse by its own weight. When it is slight, it forms a well-shaped shed material. When it is serious, the square mine has become a circle. The wellhead is shaped like a well, and the material can no longer slip out of the mine bin by gravity, forming a well-shaped shed material. The volume of the shed material accounts for about 1 / 3 to 1 / 4 of the total volume of the mine bin. As a result, the actual use volume of the mine bin becomes smaller. Can't play the role of adjusting the amount of ore

Sometimes when the blockage of shed material is very serious, the materials in the mine stop flowing, and the mine loses its function

The current commonly used method is that the workers go down into the mine bin and poke the material with iron rods to deal with the blocked shed material. The work is very dangerous and personal accidents sometimes occur.
