The bigger mechanical energy of medium cylinder, reduces the influence of powder reuniting, beneficial to discharge, and then improves the product in continuity separation operation
Quality.
As shown in Figure 2,3, heretofore described feeder trough 7（Referring to Fig. 6,7,8）, nonmagnetics collecting tank 13 and Magnetic Materials
Structure and size of the collecting tank 12 with magnetic matrix cylinder match, the left and right and top of the feeder trough using planar structure,
Bottom is identical with magnetic matrix cylinder, and using polygon groove type, button is placed on complete machine topmost, i.e. its polygon groove and magnetic matrix cylinder
It is in contact；The nonmagnetics collecting tank touches with magnetic matrix cylinder bottom connection, left and right and bottom using planar structure, on
Portion uses plane groove（Referring to Fig. 9,10,11）；The Magnetic Materials collecting tank is left and right and bottom using planar structure, top with
Magnetic matrix cylinder is identical, using arc fluting shape, is placed in the plane groove on nonmagnetics collecting tank top（Referring to Figure 12,13,
14）；The size of Magnetic Materials collecting tank must assure that it can be placed in the plane groove on nonmagnetics collecting tank top just,
Therefore, the size phase of feeder trough, Magnetic Materials collecting tank and nonmagnetics collecting tank with magnetic matrix cylinder is also specially required
Unanimously.
As shown in figure 4, the magnetic pole is square using square neodymium iron boron NdFeB permanent magnets upper and lower, left and right and the face of afterbody five
Extrude soft iron material has square high-performance neodymium iron as magnetic pole, i.e., the upper and lower of square soft iron, left and right and close magnetic system yoke end
The face homopolarity extruding of boron NdFeB permanent magnets five, and guide the magnetic line of force by the use of square soft iron material as magnetic pole；And after five faces are extruded
Square soft iron magnetic pole be arranged symmetrically being formed to pole formula structure；The adjacent magnetic of square soft iron magnetic pole after the five faces extruding
N or S are alternately present for pole, and make its energy N to reply pole formula magnetic pole simultaneously --- and S closures, formation path is shorter and magnetic resistance is relatively low
Adjacent, relative magnetic loop so that sorting space background field strength is relatively uniform；As mineral powder physical property is wide in range, in opposite side cloth
The square soft iron magnetic pole that square common neodymium iron boron NdFeB magnetic materials can be used to build the extruding of five faces to pole formula magnetic system put.
The concrete structure of the present invention, installation connected mode are as follows：
First, half range magnetic system yoke 4 is lain on non-magnetic stainless steel plate, then will be close to the square permanent magnetism of extruding at yoke
Body 11 is all fixedly arranged in the front and rear sides symmetric position of magnetic system yoke 4 by cohering the mechanical systems such as additional bolt, is close to yoke
Place's extruding is insufficient to allow later five faces extruding magnetic pole firm with the magnetic force between square permanent magnet 11 and magnetic system yoke 4, therefore
It is close at yoke extruding with needing to carry out using mechanical connection manners such as bolt or welding between square permanent magnet 11 and magnetic system yoke 4
Connection, after the completion of place safety area, and away from ferromagnetic material.Then on non-magnetic stainless steel plate, non-magnetic material is utilized
Material makes setting tool first by middle two extruding with being extruded among one of square some permanent magnets 9, one with square some soft
The extruding of one of magnetic pole iron 10 is installed together, and requires that some permanent magnets of extruding are identical with the size of soft iron magnetic pole here,
Middle part extruding is completed in the same way on the basis of this using special process measure to be extruded with square with square permanent magnet and centre
Soft iron magnetic pole group 14, double homopolarity extruding magnetic poles are now just formed, then use lower compression with square permanent magnet 3, upper compressive
Square permanent magnet 8 is extruded with square soft iron magnetic pole group 14 with some middle extruding in corresponding middle part with square permanent magnets and centre respectively
Other both sides extruding be fixed together, if lower compression square permanent magnet 3, upper compressive square permanent magnet 8 and middle part
Extruding extrudes square soft iron magnetic pole group 14 with square permanent magnet and centre and carried out by bolt of the four sides with double nut among dry
Connection, non-magnetic stainless steel plate extrude square soft iron magnetic pole group 14 with square permanent magnet around some middle extruding in middle part with middle
Surrounding is fixed；The extruding of four sides homopolarity is now formed, is extruded followed by by some centres in middle part with square permanent magnet and centres
Extrude square soft iron magnetic pole group 14 and be fixedly arranged to place and be close to out of harm's way in the magnetic system yoke 4 of part assembling at yoke
Extruding is mainly connected by magnetic system yoke 4 with directly over square permanent magnet 11 with being close to extruding at yoke with square permanent magnet 11
Preformed hole when connecing, with being looped around middle part extruding square permanent magnet and middle four extruded around square soft iron magnetic pole group 14
The bolt of the non-magnetic double nut not carried on steel plate is attached；The soft iron pole assemblage of such five face homopolarity extruding is completed.
Other half range is similarly assembled, said herein is accordingly to ensure that five face same polarity magnetic poles can be formed at the soft iron magnetic pole of everywhere.And
And ensure that the length sum of top and the bottom permanent magnet is equal to the length sum for being close to that permanent magnet is extruded at yoke, it is also necessary to squeeze with middle part
Pressure is equal with the width sum of square soft iron magnetic pole group with square permanent magnet and centre extruding.The width of top and the bottom permanent magnet and squeeze
Press the width of permanent magnet identical, respectively less than extrude soft iron magnetic pole certain length.As shown in figure 4, closure permanent-magnet magnetic of the present invention
The assembling of system is assembled to form according to polar requirement, and poly- magnetic technology magnetizing polylith different size not is extruded using five face homopolarities
Same permanent magnetism permanent magnet is realized by extruding the form of soft iron.
Then, four frames 1 are lain in non-magnetic plane, four will be welded at the corner location of support platform 2
The top of frame 1；Then the magnetic system yoke 4 for having completed assembling is welded on to the top of one of the left and right sides of support platform 2, then together
The magnetic system yoke 4 that another half range has been completed to assemble is welded on support platform 2 and be symmetrically arranged by sample locates a upper lateral part, so just
