Method and device for removing metallic material of high-speed conveyer belt bulk cargo

Abstract

The invention discloses a method and a device for removing metal in high-speed conveyer belt bulk materials. Compared with the prior art, the method is characterized in adding a second metal detector, an AND gate logic control circuit, a material pile strickle and a conveyer belt bracket; a plurality of single components form a control subsystem connected with a console cabinet. The method is suitable for conveying the bulk materials by means of conveyer belts in steel, wharf, logistics, mining and storage industry. The method has the advantages of integrating communication, control and data exchange, enabling linkage with the console cabinet, removing the non-magnetic metal of high-speed conveyer belt, and improving equipment safety and conveyance efficiency of the high-speed conveyer belt.

Description

(1) Technical field [0001] The invention relates to a method and a device for removing metal objects in bulk materials on high-speed conveyor belts. (2) Background technology [0002] The belt conveyor for long-distance transportation of granular and powdery bulk materials (such as iron ore, etc.) is a kind of efficient transportation equipment today, and is widely used in metallurgical enterprises, docks, ore yard storage and other industries. During the transportation of bulk materials, metal wastes are often mixed in, especially the long and sharp metal objects that are mixed in are the most harmful. Belt, so that the entire conveyor belt cut off production, resulting in huge losses. The metals mixed in bulk materials such as coal and ore are basically iron and steel substances. These substances are generally mixed in during the mining, transportation and processing of ore production, such as: machinery, equipment, and tools. Parts, structural parts, waste, etc. In ord...

Problems solved by technology

However, due to the inertia of the metal objects on the conveyor belt synchronous with the conveyor belt speed, especially for high-speed conveyor belts, the iron-type magnetic-conducting material in the ore has just "broke out" from the ore, and it will be absorbed by its own Inertial throwing, and the greater the weight of the magnetic material, the easier it is to be "thrown". For this reason, sometimes "slipped" scrap steel remains on the conveyor belt, posing a threat to the safety of the high-speed conveyor belt

Chinese patent 02265152.7 discloses a "parallel recovery type iron removal device", and Chinese patent 200610008704.9 discloses a "combined magnetic ore iron remover". figure 1 When the scrap iron block 20 passes through the bottom of the iron remover 9 electromagnet 10 (the area with the largest magnetic intensity), due to the effect of the electromagnet 10, the scrap iron block 20 mixed in the mineral material 1 will be sucked, and the scrap iron block 20 will be sucked hereby. 20 must break through the resistance and gravity of mineral material 1, and then break through the ground, resulting in a time difference

[0007] In addition, for high-speed conveyor belts conveying bulk materials, there are also non-magnetic metals (such as stainless steel) in the bulk materials, which has become a new threat to the bulk material conveyor belt; while the existing technology only It can remove iron, but there is a lack of countermeasures for all-round removal of metals in bulk materials
