Description
Technical field
The present invention relates to magnetic separator field, be specially a kind of permanent magnetic pulley formula magnetic separator.
Background technology
Because the magnetic system of conventional drum type magnetic separator is installed in drums inside, cause the intensity in magnetic field non-adjustable like this, meanwhile, material is when sorting through cylinder surface, and the mechanical force that magnetic field will be far longer than cylinder itself could successfully catch useful material; In the process simultaneously contacted with cylinder surface at material, because the material formed in the material dropping process that gravity causes easily causes material extrusion phenomenon, material is caused to sort the race tail in process.
Summary of the invention
For the problems referred to above, the technical problem to be solved in the present invention is the permanent magnetic pulley formula magnetic separator providing a kind of magnetic system to be arranged on cylindrical outer, runs the problem of tail, improve the rate of recovery and the grade of useful mineral aggregate simultaneously when effectively avoiding the outer cylinder magnetic separator of tradition to select materials.
The concrete technical scheme of the present invention is as follows:
A kind of permanent magnetism internal cylinder type magnetic separating machine, comprise frame, the motor being fixed on the cylinder in frame and being connected with drum drive, described frame is also provided with the magnetic system matched with cylinder along the rotation direction of cylinder, the cross section of described magnetic system is L-shaped and magnetic system inner surface has radian, described cylinder to be coated in magnetic system and not to contact with magnetic system, the frame at described cylinder two ends is respectively equipped with the feeding-passage and tapping channel that are connected with cylinder, the blowpit for transporting magnetic material is also provided with in described cylinder, described frame is provided with the discharge channel be connected with blowpit.
Preferably, the field intensity of described magnetic system progressively strengthens along the direction of transfer of material in cylinder.
Preferably, described drum inner surface is evenly distributed with the magnetic induction rod of multiple cross section semicircular in shape.
Preferably, described blowpit is downward-sloping along the direction of transfer of magnetic material, and the below of blowpit is also provided with shaking device.
Beneficial effect of the present invention is: the magnetic system of magnetic separator of the present invention is respectively in cylindrical outer along the reverses direction of cylinder is L-shaped, material rotates in magnetic system with cylinder, magnetic material affects by magnetic system, to fall into the blowpit in cylinder transports to reclaim with drum movement to top place magnetic field dissipate; Because material is subject to the impact of magnetic system in the transmission direction all the time, magnetic upset number of times increases with the length of cylinder, as long as the cylinder long enough of internal cylinder type magnetic separating machine in theory, namely magnetic material time of staying long enough in cylinder is sorted, upset number of times is also abundant, just can realize magnetic material 100% reclaims, and provides powerful guarantee for generating profit maximization.The rate of recovery of the present invention to magnetic mineral is higher, and structure is simple, and cost is lower, is convenient to installation and maintenance.
Accompanying drawing explanation
Be described further with regard to the specific embodiment of the present invention below in conjunction with accompanying drawing, wherein:
Fig. 1 is front view of the present invention;
Fig. 2 is the sectional view along A-A face;
Fig. 3 is the perspective view of magnetic system;
Fig. 4 is the structural representation of cylinder;
Fig. 5 is the sectional view along B-B face.
Detailed description of the invention
With reference to a kind of permanent magnetism internal cylinder type magnetic separating machine shown in accompanying drawing 1-2, comprise frame 1, cylinder 4 is equipped with in frame 1 inside, motor 2 is housed below cylinder 4, motor 2 is connected by belt 3 with cylinder 4, the direction of rotation of reference accompanying drawing 1 intermediate roll, for turning clockwise, according to the left side that cylinder 4 is fixed in the direction of rotation determination magnetic system 5 of motor, is rotated counterclockwise as drum rotating is reversed, is fixed on the right side of cylinder by magnetic system; With reference to shown in accompanying drawing 3, magnetic system 5 design section is L-shaped and inner surface has radian, its radian, length, height and bottom width all match with cylinder 4, left one side of something of cylinder 4 is all covered by magnetic system 5 except top, magnetic material can be rotated up motion by magnetic system 5 attraction with cylinder 4, arrives top magnetic field dissipate then with gravity fall.
The support be connected with frame 1 is had in the inner cross-under of cylinder 4, support is fixed blowpit 9, blowpit 9 is positioned at cylinder 4 center, magnetic field dissipate position, slidable 4 top, when namely magnetic field dissipate magnetic material falls into Action of Gravity Field in blowpit 9, conveniently discharging is reclaimed, improve discharging efficiency, preferably blowpit 9 is designed to along throughput direction downward-sloping, vibrating device 10 is set bottom blowpit simultaneously, the discharge channel 8 of discharging opening connection frame 1 right-hand member of blowpit 9, magnetic material falls in discharge channel 8 with blowpit 9 and reclaims.
The frame 1 at the two ends, left and right of cylinder 4 is divided and is provided with feeding-passage 6 and tapping channel 7, three is interconnected, for the material sorted enters in cylinder 4 by tapping channel 6, magnetic material is reclaimed by discharge channel 8, and remainder material is then carried by tapping channel 6 and reclaimed.
In the middle of concrete enforcement, the throughput direction of the field intensity of magnetic system 5 with material progressively strengthens by decision design, and screening process can be made so more even; If magnetic field intensity started strong or consistently, then easily generation disk pack wraps up in phenomenon, cause non-magnetic material to be wrapped and together fall into blowpit 9, thus the material filtered out is impure; And the field intensity strengthening magnetic system 5 gradually effectively can avoid the generation of this phenomenon, thus evenly magnetic material is sieved.
In the middle of concrete enforcement, with reference to shown in Fig. 4-5, preferably evenly to arrange multiple magnetic induction rod 11 at drum inner surface, magnetic induction rod 11 can make the field intensity of outside magnetic system 5 in the surface superposition of magnetic induction rod, the field intensity of unit are is raised, the screening effect to weakly magnetic material can be strengthened; The rod of magnetic induction is simultaneously designed to the long rod of cross section semicircular in shape, drives material to roll, increase the number of times that magnetic material contacts with magnetic field, improve screening effect further in the process that cylinder 4 overturns.
The course of work of the present invention is as follows: during screening, the material of band screening enters cylinder from feeding-passage, magnetic system maintains static, and cylinder rotates in magnetic system, by magnetic field, the magnetic material be adsorbed on inner wall of rotary drum is taken to drum overhead, magnetic field disappears herein, magnetic material is thrown on blowpit with Action of Gravity Field, by the vibration of vibrating device, the magnetic material on blowpit is transported to discharge channel thus discharge, and all the other are not delivered to tapping channel discharge containing materials of magnetic via cylinder.
The above; be only the better detailed description of the invention of the present invention, but scope is not limited thereto, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; the change that can expect easily or replacement, all should be encompassed within protection scope of the present invention.Therefore scope is as the criterion with the protection domain of claims.
