Abstract

The utility model relates to a magnetic separation device, in particular to an electromagnetic and permanent-magnet combined iron remover. The electromagnetic and permanent-magnet combined iron remover comprises a driving belt roller mounted on the frame, a driven belt roller, a de-ironing belt with the head and the end which are sealed arranged on the driving belt roller and the driven belt roller, wherein the driving belt roller is driven by a power device, the driven belt roller is driven by the driving belt roller through the de-ironing belt, an electromagnetic box and a permanent-magnet box are arranged on the inner side of the bottom of the de-ironing belt in the moving direction of the belt, an electromagnet is arranged in the electromagnetic box, a permanent magnet is arranged in the permanent-magnet box, and an iron-collecting hopper is arranged at the lower part of the tail end of the permanent-magnet box. The utility model can automatically separate the ferromagnetic impurities sucked from the iron remover from iron ores, and meanwhile, the electric power consumption is low.

Description

Electromagnet and permanent magnet combined type tramp iron separator

Technical field

The utility model relates to a kind of magnetic separating apparatus, specifically is a kind of electromagnet and permanent magnet combined type tramp iron separator.

Background technology

Employed tramp iron separator is generally electric magnetic iron remover on the existing ore belt conveyor that is applied in the industry production processes such as mine, harbour, steel mill, iron-smelter, start tramp iron separator when in use at first detecting the larger-size ferromagnetic sundries that is mixed in the iron ore material with the sucking-off of ferromagnetism impurity with metal detector, in the ferromagnetic impurity of sucking-off, also sucking-off has been taken away a large amount of ores and has been caused bigger waste.And, in the process of the separated conveying of ferromagnetism impurity, need to keep for a long time the suction of calutron, thereby electric energy loss is also bigger.

Summary of the invention

Technical problem to be solved in the utility model is that providing a kind of can separate with iron ore automatically to the ferromagnetism impurity of tramp iron separator sucking-off, simultaneously the little electromagnet and permanent magnet combined type tramp iron separator of power consumption.

Electromagnet and permanent magnet combined type tramp iron separator of the present utility model includes the iron belt that unloads of the active leather belt roller that is installed on the framework, passive leather belt roller and the head and the tail sealing on active leather belt roller and the passive leather belt roller, initiatively leather belt roller is driven by power set, and passive leather belt roller is driven by unloading iron belt by the active leather belt roller; Be disposed with electromagnetic cage and permanent magnetism case unloading the traffic direction of iron belt bottom inside, be mounted with electromagnet in the electromagnetic cage, be mounted with permanent magnet in the permanent magnetism case along belt; Below permanent magnetism case end, be provided with collection iron charge bucket.

Described traffic direction compartment of terrain, outer surface upper edge of unloading iron belt is provided with a plurality of horizontal iron blend stops that unload.

The working face of described electromagnetic cage and run to its below the iron belt that unloads be positioned at horizontal level, the working face of described permanent magnetism case and run to its below the relative horizontal direction in the position of unloading iron belt be inclined upwardly.

The utility model has formed electromagnetism section and permanent magnet segments successively along unloading the iron belt traffic direction, makes can be returned at the permanent magnetism paragraph by the iron ore of electromagnetism section sucking-off, has reduced the waste of iron ore; In addition, because ferromagnetism impurity separates the transportation section by the suction of permanent magnetism case maintenance to it at it, and electromagnetic cage only is responsible for when metal detector detects ferromagnetism impurity the impurity sucking-off, thereby electromagnetic cage do not need long-time energising, thereby greatly reduces the consumption of electric energy.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

The specific embodiment

As shown in the figure, what this electromagnet and permanent magnet combined type tramp iron separator comprised the active leather belt roller 1 that is installed on the framework, passive leather belt roller 2 and the head and the tail sealing on active leather belt roller and the passive leather belt roller unloads iron belt 3, expect that defeated the belt bottom inside sets gradually electromagnetic cage 4 and the permanent magnetism case 5 of having settled electromagnet and permanent magnet respectively along the traffic direction of belt, collection iron charge bucket 6 is set below permanent magnetism case end.The outer surface compartment of terrain of unloading iron belt 3 is provided with a plurality of horizontal iron blend stops 7 that unload, to guarantee that bigger ferromagnetism impurity can move with unloading iron belt.The working face of electromagnetic cage 4 and the iron belt that unloads that runs to its below are positioned at horizontal level, and the working face of permanent magnetism case 5 and the relative horizontal direction in the position of unloading iron belt that runs to its below are inclined upwardly, and can separate preferably to guarantee iron ore.

In the course of the work, the ore belt conveyor carries ore materials to pass through from the tramp iron separator below, when metal detector detects the larger-size ferromagnetic sundries that is mixed in the iron ore material, start electromagnet and permanent magnet combined type tramp iron separator of the present utility model immediately according to signal, at this moment, motor reducer drives leather belt roller and unloads iron belt 3 work, moment starts ultrastrong magnetic field (a few approximately second) to the electromagnetic cage 4 that level is installed simultaneously, ferromagnetic impurity and iron ore are picked up simultaneously, the iron sheet that unloads by operation takes iron ore and ferromagnetism impurity to magnetic induction intensity more weak permanent magnetism case 5 belows, because of the iron ore magnetic conductivity a little less than, separation through the permanent magnetism case, fall back on the ore belt conveyor, and the iron belt that unloads that larger-size ferromagnetism impurity is moved because of magnetic conductivity is strong is brought in the collection iron charge bucket 6, thereby realized that iron ore separates deironing.Entire work process is only planted somewhat, electromagnetic cage moment starts ultrastrong magnetic field only several seconds, and metal detector if do not detect is when having larger-size ferromagnetic sundries in the iron ore material on the belt conveyor, electromagnet and permanent magnet combined type tramp iron separator quits work, and has saved the energy consumption of using tramp iron separator widely.
