Description of the embodiments

In order to make the object technical scheme and the beneficial effects of the present utility model clearer, the following detailed description of the preferred embodiments of the present utility model will be given with reference to the accompanying drawings, so as to facilitate understanding of the skilled person.

In the drawings, the direction a is indicated as a lateral direction, the direction B is indicated as a longitudinal direction, and the direction a and the direction B are directions perpendicular to each other in the horizontal direction.

Referring to fig. 1 to 4, an oxidized ore screening apparatus for beneficiation, which can improve the vibration effect of oxidized ore by arranging a screen of a vibrating screen to be horizontally movable while vibrating up and down.

The oxidized ore screening apparatus shown in fig. 1 to 4 mainly comprises a bracket 1 and a screening box 2 mounted on the bracket 1 through a spring 204, wherein a vibrating motor 5 is fixedly mounted at the bottom of the screening box 2. In the mineral separation process, when mineral powder flows from the vibrating box, the vibrating motor 5 is started to enable the screening box 2 to vibrate up and down to screen the oxidized mineral powder in a vibrating mode, and therefore mixed mineral powder is separated into coarse ore, semi-concentrate and concentrate.

The screening box 2 is internally provided with an inclined primary screen 3, a secondary screen 4 and a bottom plate 6, so that a coarse ore outlet 201, a semi-concentrate outlet 202 and a concentrate outlet 203 are formed at the lower end of each lamellar structure, so that mineral powder flows in from the upper end of the screen in the longitudinal direction B, and after screening, can flow out from each outlet at the lower end of the screen. The mesh opening of the second-level screen 4 is smaller than that of the first-level screen 3, so that the mineral powder is subjected to multi-level screening. After screening, coarse ore, semi-concentrate and concentrate flow out from the upper parts of the first-stage screen 3, the second-stage screen 4 and the bottom plate 6 respectively, and mineral powder particles with different sizes can be conveyed to different process positions through belts for treatment, so that the screening efficiency of oxidized mineral powder is improved.

As shown in fig. 1 and 3, the first-stage screen 3 and the second-stage screen 4 are respectively connected with the side wall of the screening box 2 in a sliding manner in the transverse direction a through a first sliding rod 303 and a second sliding rod 403, the sliding connection direction is perpendicular to the inclination direction of the first-stage screen 3 and the second-stage screen 4, and a first side plate 301 and a second side plate 401 which are fixedly arranged at the outer ends of the first sliding rod 303 and the second sliding rod 403 are respectively provided with a first vertical plate 302 and a second vertical plate 402. The first vertical plate 302 and the second vertical plate 402 are provided with a first chute 3021 and a second chute 4021 having opposite inclination directions. The stand 101 is fixedly installed on the bracket 1, and the stand 101 is provided with a first roller 1011 and a second roller 1012 which slide corresponding to the first chute 3021 and the second chute 4021. When the vibration motor 5 is started to vibrate the screening box 2 up and down, the first chute 3021 and the second chute 4021 contact the first roller 1011 and the second roller 1012, respectively, so that the primary screen 3 and the secondary screen 4 reciprocate horizontally and laterally. When coarse ore and semi-concentrate roll on the first-stage screen 3 and the second-stage screen 4 respectively, the screens can vibrate up and down and reciprocate in the transverse direction A, so that the screening effect of the first-stage screen 3 and the second-stage screen 4 can be improved, the construction of a circulating conveyer belt in the traditional screening process is avoided, and the process route is shortened.

Finally, it is noted that the above-mentioned preferred embodiments are only intended to illustrate rather than limit the utility model, and that, although the utility model has been described in detail by means of the above-mentioned preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the scope of the utility model as defined by the appended claims.
