Background
In the operation process of the large-scale ball mill, ores, water, ore grinding media and the like firstly pass through the feeding box, slide into the feeding flow pipe from the feeding box, enter the barrel body of the ball mill, and are extruded, collided and impacted in the barrel body to reach the required ore grinding granularity. Common feed box is square structure, and the bottom is direct to link to each other with the feeder pipe, at ball mill actual operation in-process, because the square box of feed receives the impact of ore, medium for a long time, industry normal water or return water corrode, lead to square box welt life of feed short, and the square box of feed often takes place the box and grinds the condition such as leaking ore, box receives impact deformation. And because the feeding square box is crowded in space and high in position, the operations of replacing the lining plate and repairing the box body by personnel belong to limited space and high-altitude operation, the operation difficulty is high, and the operation risk is high.
SUMMERY OF THE UTILITY MODEL
To sum up, an object of the utility model is to provide a large-scale overflow type ball mill feed box of wear-resisting shock-resistant.
The utility model aims at realizing through the following technical scheme:
a feeding box of a wear-resistant impact-resistant large-scale overflow ball mill is an integral body consisting of a square flange, a feeding box, a sample placing box and a circular flange, wherein the square flange is connected with the feeding box; the feeding box is connected with the lofting box; the sample placing box is connected with the circular flange.
The feed box is a square structure with dimensions (length, width, height =1000, 200).
The sample placing box is formed by welding 2 sample placing box side plates, a sample placing box front plate and a sample placing box rear plate.
The sample placing box side plate 3 is a bent side plate structure formed by bending based on the bottom edge of an irregular quadrangle and based on the inner diameter of a circular flange as the curvature.
The sample placing box front plate and the sample placing box rear plate are of a bent plate structure formed by bending on the basis of the bottom edge of an isosceles trapezoid and the inner diameter of a circular flange as the curvature.
The distance between the square flange and the circular center of the circular flange is 469mm, and the circular center of the circular flange forms a 30-degree inclination included angle with the horizontal direction.
The sample placing box side plate and the sample placing box rear plate are main ore flushing surfaces, and lining plates are paved on the inner sides of the sample placing box side plates and the sample placing box rear plate.
Compared with the prior art, the utility model has the advantages of:
1. the utility model discloses life is longer, and the ball mill feed box adopts lofting nature structure, compares with traditional square chest, and ore transportation inclination is big, can effectively reduce the ore and strike the lining board wearing and tearing, and welt life is longer, and strikes face (6 loft case curb plates and 7 loft case back plates) welt thickness through the thickening, can guarantee basically that funnel welt wearing and tearing cycle is the same, accomplishes the change of same cycle.
2. The utility model discloses a structure is more firm, compares with traditional feeder box, adopts lofting nature structure, and whole bending strength is bigger, and the feeder box is difficult to take place to warp and leak thick liquid, and especially board welded junction department compares with traditional feeder box, and the face of weld receives the impact less, and the weld is not fragile.
3. The utility model discloses a fluid type structure, ore, medium are in transportation process, and the resistance that receives is littleer, and the ore is carried more smoothly, and difficult ore, the medium jam feed box phenomenon of taking place.
4. The utility model discloses it is more convenient to overhaul the maintenance, directly demolishs circular flange department bolt and can change the feeding flow tube, need not set up the scaffold frame, and the operation is safer, and is high-efficient, and the whole stand wear and tear shock resistance of feeder box strengthens, and the maintenance cycle extension has significantly reduced maintainer's intensity of labour.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a front view of the present invention.
Fig. 3 is a view a-a of fig. 2.
The specific implementation mode is as follows:
the invention will be further explained with reference to the drawings:
as shown in figures 1, 2 and 3, the feeding box of the large-scale overflow ball mill is a whole body consisting of a square flange 1, a feeding box 2, a lofting box 3 and a circular flange 4, and is characterized in that: the square flange 1 is connected with a feeding box 2; the feeding box 2 is connected with the lofting box 3; the sample placing box 3 is connected with a circular flange 4; the feedbox 2 is a square structure with dimensions (length, width, height =1000, 200); the lofting box 3 is formed by welding 2 lofting box side plates 32, a lofting box front plate 31 and a lofting box rear plate 33.
The sample placing box side plate 32 is a bent side plate structure formed by bending on the basis of the bottom edge of an irregular quadrangle and by taking the inner diameter of the circular flange 4 as the curvature.
The sample placing box front plate 31 and the sample placing box rear plate 33 are of a bent plate structure formed by bending on the basis of the bottom edge of an isosceles trapezoid and the inner diameter of the circular flange 4 as the curvature.
The distance between the square flange 1 and the circular center of the circular flange 4 is 469mm, and the circular center of the circular flange 4 forms an inclination included angle of 30 degrees with the horizontal direction.
The sample placing box side plate 31 and the sample placing box rear plate 33 are main ore flushing surfaces, and lining plates are paved inside the sample placing box side plate and the sample placing box rear plate.
Examples
Firstly, welding a square flange 1 and the upper part of a feed box 2, and fixedly connecting the square flange and the lower end of an ore feeding belt hopper through bolts, and mounting 4 circular flanges and fastening bolts in advance. And (3) measuring and determining the installation position of a lofting funnel, the transverse necking size H of the lofting box and a 30-degree inclination included angle with the horizontal direction.
The lining plates are manufactured on the basis of the lofting box side plate 32 and the lofting box rear plate 33, and then the lining plates are welded on the lofting box side plate 32 and the lofting box rear plate 33.
Splicing and welding 3 the folded lofting box side plates 32, the lofting box front plate 31 and the lofting box rear plate 33 to form the lofting box 3,
and finally, welding the circular flange 4 with the lower part of the sample placing box 3.
The implementation effect is as follows:
after implementing, ball mill feeder box welt life is longer, is one time of driven feeder box welt life, can guarantee that the inside wearing and tearing of funnel welt are even, accomplishes to change with the cycle.
After the operation for 2 years, the feeding box has no deformation and slurry leakage, and no open welding is found at the welding joint of the plates.
After the ore and the medium are conveyed, the resistance to the ore and the medium is smaller, the ore is conveyed more smoothly, and the phenomenon that the feeding box is blocked by the ore and the medium is not found.
After the implementation, the maintenance of feeder box is more convenient, when carrying out feeding flow tube operation, need not set up the scaffold frame, and the activity duration reduces 6 hours, and the whole life of feeder box is expected to be more 2-5 years than traditional feeder box.
