Description

Technical Field

[0001] The utility model relates to the technical field of color sorters, and specifically discloses a dual-function color sorter capable of selecting concentrates and removing iron. Background Art

[0002] Color sorter is an optical, mechanical and electrical device that can sort and purify materials based on the color or shape differences of materials through photoelectric detection and image processing. It is widely used in the fields of grain and ore screening, and has been rapidly promoted due to its high selection rate, impurity removal rate and carry-out ratio.

[0003] The existing color sorter uses the vibration of the vibrator to transport the ore in the feed hopper to the belt conveyor for transportation. Since the ore contains a large amount of dust particles, it is easy to cause errors in the recognition of the CCD sorting mechanism. In addition, the particle size of the good ore after sorting by the color sorter is not uniform, resulting in poor sorting effect of the color sorter. At the same time, before sorting the ore, the ore raw materials need to be crushed first. After the ore is crushed, many small ores have iron substances such as mechanical iron and magnetite on the surface. The color sorter can only sort the ore, but cannot effectively remove the iron impurities in the ore. Utility Model Content

[0010] Beneficial effects:

[0011] 1. The dual-function color sorter capable of selecting concentrate and removing iron can magnetically attract the mechanical iron contained in the ore to the bottom of the conveyor belt of the second belt conveyor through the weak electromagnet before ore sorting through the magnetic force. At the same time, the second belt conveyor can drive the mechanical iron to move synchronously with the conveyor belt, and then the second scraper can be used to remove the mechanical iron at the bottom of the conveyor belt to avoid the mechanical iron at the bottom of the conveyor belt. The color sorter can well remove the mechanical iron in the crushed ore and prevent the accumulation of large pieces of mechanical iron, thereby affecting the subsequent strong magnetic separation.

[0012] 2. The dual-function color sorter capable of selecting concentrate and removing iron can magnetically adsorb magnetite and its intergrowths in good quality ore on the outside of the magnetic sleeve through strong electromagnets, thereby effectively removing iron-containing impurities in the ore. At the same time, the motor can drive the magnetic sleeve to rotate around its own axis, and then the first scraper can remove the iron-containing impurities adsorbed on the outside of the magnetic sleeve. This structure is more conducive to the removal of iron impurities in subsequent flotation, pickling, strong magnetic and other processes by adopting the combination of weak magnetism and strong magnetism, which can be beneficial to the improvement of iron elements in sands of different codes, greatly reducing costs and improving ore quality.

[0013] 3. The dual-function color sorter capable of selecting concentrate and removing iron can filter and screen the selected good ore by installing a stainless steel screen on the inner side of the second row hopper, so that the color sorter can screen out semi-finished products with high particle size accuracy and meet production needs, thereby improving the sorting effect of the color sorter on good ore. At the same time, the stainless steel screen can be driven to vibrate on the inner side of the second row hopper through the drive of the first vibrator, thereby preventing the ore particles from clogging the sieve holes on the stainless steel screen, thereby improving the ore screening accuracy, ore particle size, and overall ore output rate.
