Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to a kind of feeding components of disc feeder, specifically to a kind of feeding disc of disc feeder for seawater ore dressing. BACKGROUND
[0002] Part of mine is adjacent to ocean, and seawater ore dressing is usually used in mine concentrator. On the other hand, high salinity water is mixed in the ore mined underground in such mine. Part of tailings produced by mine ore dressing is filled into underground goaf after concentration, and the part of filling tailings will enter ore crushing system with the progress of mining. The crushed ore is stored in fine ore bin for feeding of grinding system. The ventilation condition of fine ore bin is generally poor, so the ore maintains high salinity water, which causes serious corrosion of vulnerable parts of disc feeder, especially the feeding disc.
[0003] At present, there is no feeding disc special component for disc feeder suitable for seawater ore dressing. The disc component of feeding machine as prior art mainly has the following defects: the ore discharged from fine ore bin has non-uniform particle size and is accompanied by seawater corrosion, which causes rapid corrosion, wear or deformation of feeding disc during use, and frequent replacement is needed, which not only increases maintenance cost, but also affects production continuity. SUMMARY
[0004] The technical problem to be solved by the utility model is to provide a feeding disc of disc feeder suitable for seawater ore dressing, which can adapt to seawater ore dressing feeding environment, has good seawater corrosion resistance and wear resistance, and has the characteristics of simple manufacturing, low cost and long service life.
[0005] The technical scheme of the utility model is as follows:
[0006] A feeding disc of disc feeder suitable for seawater ore dressing, comprising a base disc, a corrosion-resistant and wear-resistant layer is fixedly arranged on the base disc, and the corrosion-resistant and wear-resistant layer comprises a framework mechanism; the framework mechanism comprises a ring of steel bars surrounding edge welded and fixed to the upper side edge of the base disc, a plurality of hexagonal nuts welded and fixed to the upper side of the base disc, and steel wires connected between different hexagonal nuts; the framework mechanism has corrosion-resistant and wear-resistant material in the gap, and the upper surface of the corrosion-resistant and wear-resistant material is flush with the upper side of the steel bar surrounding edge.
[0007] Preferably, the hexagonal nuts are provided with inner, middle and outer three circles; wherein the four hexagonal nuts in the inner circle are arranged in a square, the four hexagonal nuts in the middle circle are arranged in a square, and the center points of the four hexagonal nuts are perpendicular to the four sides of the square formed by the four hexagonal nuts in the inner circle, and the eight hexagonal nuts in the outer circle are arranged in a regular octagon.
[0008] Preferably, the ratio of the corrosion and wear resistant layer to the base disc thickness is (0.8-1.2):1.
[0009] The beneficial effects of the present application are as follows:
[0010] First, the present application is based on a base disc, and a corrosion and wear resistant layer composed of a framework mechanism and corrosion and wear resistant material is added. As a corrosion and wear resistant layer, the corrosion and wear resistant layer is more resistant to corrosion and wear under high humidity and high salt conditions during use, thereby prolonging the service life of the feeding disc and reducing maintenance costs.
[0011] Second, the raw materials of the present application are low in price, easy to obtain and simple in manufacturing process, and can effectively target the specific complex process conditions of seawater beneficiation, thereby playing a role in reducing costs and increasing efficiency during the powder ore bin feeding stage.
[0012] Third, the base disc of the present application can be recycled. When the corrosion and wear resistant layer is worn to a certain extent and the exposed part of the base disc surface is exposed, the remaining framework material and corrosion and wear resistant material can be cleaned, and the base disc that is still intact can be used to process a new corrosion and wear resistant layer to make a new feeding disc, thereby realizing the recycling of the base disc.
[0013] Fourth, the framework material (reinforcing steel bar, steel wire and hexagonal nut) of the present application can be made of waste materials, thereby reducing the manufacturing cost of the feeding disc and realizing the recycling of mine waste materials. BRIEF DESCRIPTION OF DRAWINGS
