A tailing sand filling sand bin device

Abstract

The invention relates to the field of mining equipment, in particular to a sand bin filling device for tailing sand, which includes a sand bin and a drop opening arranged on the bottom side of the sand bin. An auger shaft is rotatably connected to the middle of the sand bin, and the circumferential side wall of the lower part of the auger shaft is An auger is provided, the lower end of the auger shaft passes through the outlet and is hinged with a sliding sand tank, the right end of the sliding sand tank is provided with an adjustment piece, the left side of the adjustment piece is provided with an arc surface, and the upper part of the sand bin is provided with a driving auger shaft to rotate The driving assembly of the sand bin is symmetrically fixed and connected with the cylinder through the ring frame outside the middle part of the sand bin; the invention prevents the tailing sand from blocking the drop opening by rotating the auger in the sand bin, and at the same time adjusts the vertical movement of the left end of the sand slide tank. Adjust the falling and accumulating area of ​​the tailings to realize the expansion of the accumulation area of ​​the tailings. At the same time, the rotation of the sliding sand tank is driven by the auger shaft to further expand the accumulation area, which can reduce the tailings caused by excessive tailings accumulation to a certain extent. Collapse accidents, and avoid tailings clogging too high at the drop opening, and improve the falling efficiency of tailings.

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
