Detailed Description
Embodiments of the present utility model will now be described with reference to the accompanying drawings.
As shown in fig. 1 to 4, the screening device for a sintering material discharging hopper 1 of the present embodiment includes: the screening device comprises a discharging hopper 1, a hollowed screening grid 2 and a vibrator 6, wherein a screening opening 14 is formed in the side wall of the discharging hopper 1, the screening grid 2 is arranged in the discharging hopper 1, the screening grid 2 is obliquely arranged, one side of the screening grid 2 is in butt joint with the screening opening 14, the other side of the screening grid 2 is higher than the screening opening 14, and the vibrator 6 is connected with the screening grid 2. The inclination angle of the screening grid 2 with respect to the horizontal is 45 deg. to 50 deg.. The upper opening of the lower hopper 1 is in butt joint with the feeding belt 11, the lower opening of the lower hopper 1 is in butt joint with the receiving belt 12, the lower end of the screening grid 2 extends out of the lower hopper 1 from the screening opening 14, and a containing barrel 5 is arranged below the lower end of the screening grid 2. When the sintered material 13 conveying line is ready to work, the vibrator 6 is started in advance, the screening grid 2 is in a slightly vibrating state, after the material 13 on the feeding belt 11 enters the discharging hopper 1, the particle raw material falls onto the receiving belt 12 along the hollowed-out part of the screening grid 2, and the large-block impurities or ore blocks blocked from screening by the screening grid 2 fall through the screening opening 14 by slightly vibrating and then slide into the receiving barrel 5, so that post personnel only need to check the wearing condition of the screening grid 2 periodically and replace the screening grid in time, and the large-block impurities or ore blocks in the receiving barrel 5 can be cleaned in time.
As shown in fig. 2 and 3, the screening grid 2 comprises at least three side-by-side stringers 7, between two adjacent stringers 7 a chute 9 is formed. The blanking groove 9 is hollowed out, and the granular raw materials can pass through the blanking groove 9 and fall into the material receiving belt 12. The large-scale impurity or ore blocked by the screening grid 2 can slide down the blanking groove 9, and the lower end of the blanking groove 9 points to the screening opening 14, so that the large-scale impurity or ore can be discharged more smoothly.
As shown in fig. 3, the screening grid 2 further comprises cross members 8, the cross members 8 being connected across at least two longitudinal beams 7, the cross members 8 being connected to the longitudinal beams 7 below the longitudinal beams 7. The cross beam 8 can strengthen the structural strength of the screening grid 2, and the problem that the material 13 in large blocks smashes the longitudinal beam 7 to deform to expand the material dropping groove 9 so as to be incapable of effectively screening out large-block impurities or ores is avoided. And the cross beam 8 is positioned below the longitudinal beam 7, so that the reinforced structure is realized, and meanwhile, large impurities or ores on the material dropping groove 9 are not blocked.
The screening opening 14 is provided with a baffle plate 3, and the upper end of the baffle plate 3 is rotationally connected with the side wall of the discharging hopper 1. The striker plate 3 that upper end rotation is connected keeps vertical state under self gravity effect, blocks normal material 13 roll-off, and when big debris or ore was stopped the landing by screening grid 2, big debris or ore can dash out striker plate 3 because of the weight is big and drop down outside hopper 1. In this embodiment, as shown in fig. 4, at least two baffle plates 3 are located side by side in the screening opening 14, and the upper ends of the baffle plates 3 are rotatably connected with the discharging hopper 1 through pin shafts 10. When the large sundries or ores are blocked by the screening grids 2 to slide off, the large sundries or ores wash off the corresponding baffle plates 3 on the paths of the large sundries or ores and then fall out of the discharging hopper 1 from the screening opening 14, and at the moment, the other baffle plates 3 are still vertical, so that normal particle raw materials are prevented from falling out of the screening opening 14.
The upper end of the screening grid 2 is rotationally connected with the discharging hopper 1. In this embodiment, the upper end of the screening grille 2 is mounted on the side wall of the blanking hopper 1 by bolts. The embodiment also comprises a bracket 4, wherein the bracket 4 is positioned outside the discharging hopper 1, and the screening grid 2 is erected on the bracket 4. The upper end of the screening grid 2 is rotationally connected, the lower end is supported by the support 4, the screening grid 2 can vibrate freely under the drive of the vibrator 6, and the installation mode is convenient to assemble and disassemble, the screening grid 2 can be disassembled when screening is not needed, and the screening grid 2 can be conveniently additionally arranged when the screening is needed. If the screening grids 2 are required to be maintained and replaced or the screening grids 2 with different specifications are replaced, spare parts of the screening grids 2 can be manufactured in advance, and when the feeding belt 11 is not fed, replacement operation can be completed only by disassembling a plurality of bolts, so that the field use effect is obvious.
An elastic cushion is arranged between the screening grille 2 and the bracket 4, and the term "elastic" refers to that the screening grille 2 can rebound to a certain extent so as to buffer vibration of the screening grille 2, and can be silica gel, rubber, latex, cork, soft sealing glue or other materials.
