Abstract
The utility model relates to a direct-current type magnetic separator, comprising a material distribution module and a magnetic separation module capable of directly joining the material discharged from the material distribution module, wherein the magnetic separation module comprises a roller on the frame and a fixation magnet mounted in the roller joining material part. The magnetic separator directly joins the material and directly separates the pulp, the pulp is processed in no-obstacle magnetic separation material way. The magnetic separation speed is quite quick and the separated material does not generate magnetic-linkage breakage phenomena.
Description
Technical field
The utility model relates to a kind of DC magnetic separator.
Background technology
Existing magnetic separator is according to the difference of its base, can be divided into downflow type, reverse-flow and half reverse-flow these three types.Wherein, the downflow type magnetic separator has a cylinder and is installed in the magnetic system of below in the cylinder, and be installed in the cylinder below give the ore deposit case, ore pulp is by the magnetic system below of directly being given to cylinder for the ore deposit case, and makes the flow direction of ore pulp consistent with the direction of rotation of cylinder.When magnetic separation, non magnetic and weakly magnetic material is discharged by the gap between two base plates of direction under the pipe magnetic separator, and magnetic material is drawn onto on the surface of pipe magnetic separator, and rotates to the more weak place, magnetic field that magnetic is the edge with cylinder, by the discharging water pipe magnetic material is gathered in the concentrate hopper.Though it is relatively large that the downflow type magnetic separator is handled the ability of ore pulp, but because the magnetic material of selecting can rotate along with cylinder, and the magnetic field intensity of magnetic system can reduce to circumferencial direction gradually along the bottom of cylinder, so the suffered attraction of magnetic material on the cylinder can reduce gradually along with its rotation, the magnetic linkage easy fracture that causes magnetic material to produce, and the magnetic linkage breaking portion can be discharged from the non-magnetic material position, causes the waste of iron resource.
The structure of reverse-flow magnetic separator and downflow type magnetic separator is basic identical, ore pulp is equally by the magnetic system below of directly being given to cylinder for the ore deposit case, non-magnetic material is discharged by the mine tailing hole on the base plate, the direction of rotation of giving ore deposit direction and cylinder of different is this kind magnetic separator or the moving direction of magnetic product are opposite, make magnetic material with cylinder against being discharged in appointed part or the container to the ore deposit direction.Because this magnetic separator gives the ore deposit direction opposite with the direction of rotation of cylinder, the magnetic separation time is prolonged relatively, the rate of recovery is higher, what be suitable for the strong magnetic mineral of particulate roughly selects and scans operation, but because the same phenomenon that the magnetic linkage fracture can occur with the downflow type magnetic separator of the magnetic material that this magnetic separator is selected, so there is the problem of wasting iron resource equally in this magnetic separator; In addition, reverse-flow magnetic separator selects the import and export of case to be stopped up by ore easily, so this magnetic separator is not suitable for handling the coarse granule ore, causes its scope of application to have certain limitation.
Partly reverse-flow magnetic separator is basic identical to ore deposit direction and magnetic field suction force direction, and just ore pulp enters from trench bottom and sorts the space, so there is the magnetic linkage fracture equally in the magnetic separator of this type and selects case to import and export by problems such as ore obstructions.
Above-mentioned downflow type, the reverse-flow and half reverse-flow three types common shortcoming of magnetic separator are to adopt to select case as sorting the space, select case just need be provided with the import and export of ore pulp thereon and adopt, and have the case that selects of import and export will limit the size of the flow and the particle thereof of ore pulp, so the ability that has the magnetic separator processing ore pulp that selects case is restricted.
The name of Chinese patent 2640602Y Granted publication is called " high-recovery Wet-type permanent magnet drum type magnetic automatic machine selects machine " and provides a solution.This magnetic separator is that to want to utilize magnetic be the zone that the structure (cornerite at 200 degree between 300 degree) of big cornerite prolongs simplified magnetic separation material, can realize sorting for twice on a cylinder simultaneously, thereby can improve the rate of recovery of material.But because this magnetic separator adopts too and selects case, even if cell body is full adverse current double-decker, the speed of material handling is also relatively slow, and does not also solve problem such as magnetic linkage fracture.
The utility model content
The purpose of this utility model provides a kind of mode of direct election of utilizing and solves the DC magnetic separator that magnetic linkage ruptures and is subjected to problems such as material particles diameter restriction.
The DC magnetic separator that the utility model proposed comprises the cloth assembly and the magnetic separation assembly of the cloth material that assembly is discharged that directly continues, and this magnetic separation assembly comprises rack-mounted cylinder and is installed in continue fixed magnets in the material position of cylinder.
Described fixed magnets is by being installed in the inboard that bracing frame on the main shaft is fixed in cylinder, and the magnetic field intensity of fixed magnets is along level or approach horizontal direction and reduce gradually to the rollers roll direction.An edge of described fixed magnets is corresponding with the discharge end of cloth assembly, and another edge extends to the rotating direction of cylinder, and two edges are less than or equal to 180 with the formed interior angle of main shaft and spend.
The side-lower of described cylinder is provided with the discharging pipe fitting that sprays fluid to the cylinder direction.
The both sides of described cylinder below are respectively arranged with the non-magnetic material demarcation strip and the magnetic material demarcation strip of inclination.
Described cloth assembly comprises that the bottom is provided with the feed box of delivery outlet and is arranged on the level of feed box delivery outlet below or approaches the defeated material parts of horizontal direction.
Magnetic separation assembly in the DC magnetic separator that the utility model proposed adopts the mode of the material that directly continues that at first ore pulp is elected directly, and along with making progress earlier, rotating cylinder rotated downwards again by the material of magnetic, so, adopt the mode of the accessible magnetic separation material of this kind to handle ore pulp, not only the speed of magnetic separation is quite fast, and the material that is selected can not produce the phenomenon of magnetic linkage fracture.
