Abstract
The utility model belongs to magnetic separation equipment and relates to a magnetic system of a permanent-magnet iron remover. The magnetic system comprises a shell with an open lower end and a permanent magnet that is arranged in the shell. The permanent magnet consists of a group of main magnets and a plurality of groups of assistant magnets that are arranged around the main magnets. The S pole and the N pole of the main magnets are vertically arranged; the S pole and the N pole of the assistant magnets are horizontally arranged; and the polarity of the magnetic pole of one end of the assistant magnets that is close to the main magnets is identical to the polarity of the magnetic pole at the lower end of the main magnets. The magnetic system of the utility model has higher strength of the magnetic field at a rated suspension height. Simultaneously, under the condition of the equal strength of the magnetic field, the gradient of the magnetic field of the magnetic system is also increased substantially.
Description
Technical field
The utility model belongs to magnetic plant, relates to a kind of permanent-magnetic iron expeller magnetic to be.
Background technology
Common permanent-magnetic iron expeller magnetic system generally comprises open housing in a lower end and the permanent magnet that is installed in the housing, permanent magnet generally is made up of one group of master's magnet and some groups of secondary magnets being arranged in around the main magnet, extremely all vertical direction settings of the S utmost point of main magnet and secondary magnet and N form working face in their lower end pole surface.The permanent-magnetic iron expeller magnetic of this structure ties up under certain magnetic field intensity condition, and its saturating magnetic is more shallow, and magnetic field gradient is low, can not satisfy higher instructions for use.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of permanent-magnetic iron expeller magnetic that the magnetic field gradient of working face is high under certain magnetic field intensity to be.
Permanent-magnetic iron expeller magnetic of the present utility model is to include the open housing in a lower end and be installed in the interior permanent magnet of housing, permanent magnet is made up of one group of master's magnet and some groups of secondary magnets being arranged in around the main magnet, the S utmost point of described main magnet and very vertical direction setting of N, the S utmost point and the very horizontal direction setting of N of secondary magnet, and the pole polarity of close main magnet one end of secondary magnet is identical with the pole polarity of main magnet lower end.
The utility model is owing to concentrate setting with the same polarity magnetic pole of main magnet and secondary magnet, optimized the magnetic field after the combination, the magnetic line of force of the non-working surface of main magnet is concentrated on the working face of below to greatest extent, make it on specified suspension height, have higher magnetic field intensity, compare under equal magnetic field intensity condition simultaneously, the magnetic field gradient of magnetic system also improves greatly.
Description of drawings
Fig. 1 is the vertical section structure schematic diagram of the utility model embodiment;
Fig. 2 is that the magnetic of the utility model embodiment is the planar structure schematic diagram of working face.
The specific embodiment
As shown in the figure, permanent-magnetic iron expeller magnetic of the present utility model is to comprise housing 1, main magnet 2, secondary magnet 3, secondary magnet is arranged in around the main magnet, the S utmost point of main magnet and very vertical direction setting of N, in illustrated embodiment, the magnetic pole of main magnet lower end at the working face place is the N utmost point, the S utmost point of secondary magnet and very horizontal direction setting of N, and the mutually close end magnetic pole of secondary magnet and main magnet also is the N utmost point.
