Concrete practice mode
Example in conjunction with the accompanying drawings further describes as follows to the present invention:
A kind of Magnetic flotation machine, it is characterized in that this machine comprises: bracing frame 6-is supported on the basis by the steel frame that steel pipe is welded; Supporting disk-forms by the plate body that is fixed in the locking member 5 on the bracing frame and the center on the locking member of being supported on is provided with hole, totally four groups of supporting disks, one group of bottom that is fixed in bracing frame wherein, other three groups of middle and upper parts that are positioned at bracing frame respectively; The top of this device of ore discharge device 9-is the cylindrical shell that has adpting flange, the middle part is the bullet that is connected as a single entity with the cylindrical shell bottom, be supported in the supporting disk center hole of affixed bracing frame bottom, the bottom is for being connected with the bullet bottom and the cylindrical shell of the ore deposit valve 11 that runs in; Sorting post 3-is positioned at three groups of supporting disk centre bores of bracing frame middle and upper part, cylindrical shell by the non-magnet material making, the bottom of cylindrical shell is provided with adpting flange, by the adpting flange Joint of bolt 13 with ore discharge device top, the sorting post can be selected cylinder as shown in Figure 3, square tube shown in Figure 4, hexagon tube shown in Figure 5, octagonal tube shown in Figure 6 for use according to different needs; This overflow launder of overflow launder 2-is the staving of bottom angled, and its end is fixed in the outside on sorting post top, is provided with the ore discharge pipe at the bottom lower, and overflow launder is made by fiberglass; Magnetic is that this magnetic of 4-is three groups of annular magnet coil windings or permanent-magnet, is enclosed within the outside, sorting post middle and upper part, and every group of annular magnet coil winding is packed in respectively on three groups of supporting disks of bracing frame middle and upper part; This flowmeter of mass air flow sensor 12-is packed in the outside on bracing frame top by connecting rod and locking member, and its underpart is connected with valve and gas tube 14, and the other end of gas tube places in the bullet at ore discharge device middle part, and its top is provided with air inlet; This air dispersion device of air dispersion device 7-is the cylindrical shell that binds in top, is made by poromerics, places in the sorting post bottom its underpart and the interior gas tube Joint of bullet that places ore discharge device middle part; Ascending current device-this device comprises that being fixed in ore discharge device middle part bullet one side has the ascending current pipe 10 of valve and the ascending current ring pipe 8 that communicates with the ascending current pipe, the ring side is evenly equipped with hole for water spraying in the ascending current ring pipe, the ascending current ring pipe places in the sorting post bottom, is enclosed within the air dispersion device outside; This pipe of mineral-feeding pipe 1-is made by non-magnet material, is packed in bracing frame top by connecting rod and locking member, places in the sorting post top.
By the locking member on the supporting disk can the up-down adjustment supporting disk at the upper-lower position of bracing frame, and then change the position of magnetic system, thereby changed the Distribution of Magnetic Field in the sorting post, satisfied the needs of different minerals sorting.Be stablizing of mineral syrup liquid in the assurance sorting post, the ore discharge valve of ore discharge device can be manually also can be electronic.Mineral-feeding pipe is adjusted into the optimum position, and regulates ascending current and aeration quantity respectively by ascending current device and mass air flow sensor.
