Description
Technical field
The present invention relates to the mining equiment technical field, the specifically a kind of magnetic mineral of dry-type separation ore and high magnetic pre-selection machine of non magnetic ore of being used for.
Technical background
Along with China's steel and iron industry fast development, need the quantity of iron ore and iron ore concentrate more and more, the domestic iron ore deposit of efficient development and use is crucial, under the situation that the magnetic iron ore that easily selects reduces day by day, effectively utilize lean hematite ore, the technique of preparing and the new preparation equipment of exploitation that improve weak-magnetic iron ore are the task of top priority.But for a long time, because be not applicable to the technology and the plant equipment of sorting weak-magnetic iron ore, the weak-magnetic iron ore that grade is lower cannot not abandoned selectedly basically by the ore dressing plant, causes ore resource not make full use of.
Summary of the invention
The purpose of this invention is to provide a kind of high magnetic pre-selection machine that can efficiently separate magnetic mineral and non magnetic ore in the weakly magnetic ore.
The object of the present invention is achieved like this: include frame, it is characterized in that: described frame comprises high-order frame and low level frame, and high-order frame is provided with the distribution device of feeding mouth band ore storage bin; The low level frame is provided with strong magnet drum and belt tensioning drum, tensioning suit conveyer belt between strong magnet drum and belt tensioning drum, the belt tensioning drum end is the material feeding end of conveyer belt, strong magnet drum end is the blanking end of conveyer belt, the correspondence position of conveyer belt downside is provided with the magnetic mineral belt conveyor, is provided with the non magnetic ore belt conveyor in the blanking zone of strong magnet drum; The deflector chute outlet of distribution device places the material feeding end upside of conveyer belt; Strong magnet drum or belt tensioning drum connect driving mechanism.
Described strong magnet drum all is furnished with the static magnetic patch of relative cylinder with the barrel inboard of conveyer belt contact site.
The present invention utilizes the magnetic force of strong magnet drum, shorten the horizontal range of magnetic mineral blanking in the ore, and that non magnetic ore is not subjected to magnetic force to influence the horizontal range of blanking is long than magnetic mineral,, highly effective convenient and swift by the cooperation that turns to plate washer the magnetic in the ore, non magnetic ore are separated; The present invention also possesses long service life, is convenient to maintenance, novel structure, advantage such as simple and practical.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the vertical view of Fig. 1.
The present invention is described in further detail by example below in conjunction with accompanying drawing, but following example only is the present invention's example wherein, the rights protection scope of not representing the present invention and being limited, the scope of the present invention is as the criterion with claims.
The specific embodiment
By Fig. 1～shown in Figure 2, primary structure of the present invention is: high-order frame 11 and low level frame 6, and high-order frame 11 is provided with the star distribution device 2 of feeding mouth band ore storage bin 1; Low level frame 6 is provided with strong magnet drum 4 and belt tensioning drum 3, tensioning suit conveyer belt 7 between strong magnet drum 4 and belt tensioning drum 3, the belt tensioning drum end is the material feeding end of conveyer belt, strong magnet drum end is the blanking end of conveyer belt, and strong magnet drum 4 all is furnished with the static magnetic patch of relative cylinder with the barrel inboard of conveyer belt 7 contacts site.The correspondence position of conveyer belt 7 downsides is provided with magnetic mineral belt conveyor 10, and (the blanking zone is for being starting point with the blanking point, along the zone of the degree of 0 to 90 between running direction of conveyor belt and the vertical downward direction in the blanking zone of strong magnet drum 4.This zone can change according to the actuating speed of driving mechanism is different) in also be provided with non magnetic ore belt conveyor 9; Be provided with spacing deflector 5 near the low level support 6 in the blanking zone of strong magnet drum, the traffic direction of magnetic mineral belt conveyor 10 is parallel with the traffic direction of conveyer belt 7, and non magnetic ore belt conveyor 9 is vertical with the traffic direction of conveyer belt 7; The deflector chute outlet of star distribution device 2 places the material feeding end upside of conveyer belt; Strong magnet drum 4 connects driving mechanism 8, and driving mechanism 8 connects PLC Central Control Room electric-control system, can realize infinitely variable speeds.
During work, through ore storage bin 1 to star distribution device 2 feeds, star distribution device 2 uniform conveying adhesive tape 7 feeds to adjustable-speed, material on the conveying adhesive tape 7 of motion when strong magnet drum 4, because magnetic force sticks on the conveyer belt making property of the attraction magnetic mineral of magnetic mineral, at magnetic mineral through at the conveyer belt downside time, because the magnetic attraction of strong magnet drum weakens, magnetic mineral is fallen on the magnetic mineral band conveyer 10 by self gravitation, is transported by magnetic mineral conveyer 10; And non magnetic ore is not owing to be subjected to the magnetic force of strong magnet drum to influence the certain momentum of acquisition on conveyer belt, falling into non magnetic ore belt conveyor 9 with the parabolic track is transported, in order to prevent that the broken granule non magnetic ore of part from falling into magnetic mineral and influencing sorting quality, be provided with spacing deflector 5 near the low level support 6 in the blanking zone of strong magnet drum, finish the sorting overall process of mineral in sum.
