Tailing filling sand bin device

Abstract

The invention relates to the field of mining equipment, in particular to a tailing filling sand bin device. The tailing filling sand bin device comprises a sand bin and a falling opening arranged at the bottom side of the sand bin, wherein an auger shaft is rotationally connected in the middle of the sand bin, an auger piece is arranged on the circumferential side wall of the lower part of the auger shaft, the lower end of the auger shaft penetrates through the falling opening and is hinged with a sand sliding groove, an adjusting piece is arranged at the right end of the sand sliding groove,an arc-shaped surface is arranged on the left side of the adjusting piece, a driving assembly for driving the rotation of the auger shaft is arranged on the upper part of the sand bin, and air cylinders are symmetrically and fixedly connected outside the middle part of the sand bin through an annular frame. Tailings are prevented from blocking the falling opening by rotating the auger piece in thesand bin, and meanwhile, the falling accumulation area of the tailings is adjusted by adjusting the upward and downward movement of the left end of the sand sliding groove, so that the accumulation area of the tailings is enlarged; meanwhile, the sand sliding groove is driven by the auger shaft to rotate, the accumulation area is further enlarged, the tailing collapse accident caused by too highaccumulation height of the tailing is reduced to a certain extent, the tailings are prevented from blocking the falling opening too high, and the falling efficiency of the tailings is improved.

Description

technical field [0001] The invention relates to the field of mining equipment, in particular to a tailing sand filling sand bin device. Background technique [0002] The filling mining method has the advantages of improving resource recovery rate, protecting the environment, ensuring mining safety and ensuring sustainable development of mines, etc., and has become the development trend of the mining industry. In the prior art, the lower part of the sand bin used for tailings filling construction is usually conical, and a drop opening is opened at the bottom end of the conical shape. [0003] When the sand bin device is in use, the tailings flow freely in the sand bin, which is likely to cause blockage of the filling opening, and as the tailings continue to fall from the outlet, the falling tailings are easy to accumulate, and the tailings are blocked. If the accumulation of tailings is too high, when the tailings are transported, it is easy to cause the collapse of the tail...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the above-mentioned shortcomings existing in the prior art, the present invention provides a device for filling the sand bin with tailings, which can effectively solve the problem of the prior art that the tailings flow freely in the sand bin during use, which may easily cause the problem of filling the opening. Moreover, as the tailings continue to fall from the outlet, the falling tailings are easy to block, and the tailings are too high, so that when the tailings are transported, it is easy to cause the collapse of the blocked tailings, resulting in Certain safety accidents, at the same time the tailings clogged too high, easy to contact the drop, thus to a certain extent, affect the problem of tailings falling from the drop
