Problems solved by technology

[0005] In addition, the volume of the sand bin is small and the ability to store tailing mortar is low. Therefore, when the amount of filling slurry needs to be relatively large, multiple sand bins need to be installed , and even multiple filling equipment, which further increases the complexity and cost of the equipment

Embodiment Construction

[0043] like figure 1 As shown, the filling equipment according to the embodiment of the present invention further includes a filling slurry concentration adjusting device which supplies water to the stirring device so as to adjust the filling slurry concentration.

[0044] More specifically, the device for adjusting the concentration of the filling slurry includes a pool 4 for storing water, and the pool 4 supplies water to the stirring device through a water supply pipeline; a liquid level gauge 41 arranged on the pool for indicating the water level in the pool 4; a flow meter 44, Flowmeter 44 is used for detecting the amount of the water that is supplied to stirring device from pond 4; With flow regulating valve 43, flow regulating valve 43 is used for regulating from pond to stirring device, for example the amount of the water that mixing hopper 15 (discussion below) supplies . In addition, a gate valve 42a may also be provided on the water supply pipeline for disconnecti...

Abstract

The present invention discloses a filling device and filling process, wherein the filling device includes: a deep cone thickener used for storing and concentrating tailing paste; a cementing material storehouse used for store cementing material; a stirring device used to receive concentrated tailing paste and cementing material from the deep cone thickener and the cementing material storehouse tomix them and stir to obtain filling paste; and a conveyer used for receiving filling paste from the stirring device and conveying the filling paste to mine goaf. By using deep cone thickener, the filling device through the invention has better concentrating efficiency, higher concentrating degree without using a filter for moisture abstraction operation to concentrated tail paste, hence the device is simple and cost low.

Description

technical field [0001] The invention relates to a mine filling equipment, in particular to a filling equipment with a deep cone thickener. Background technique [0002] Mine filling equipment is used to fill the mining area left after mining. Traditional mine filling equipment includes sand bins, which are used to concentrate or store tailings mortar. Low-concentration tailings mortar is input from the top of the sand bin. After the sediment in the bin is concentrated, it is discharged through the sand discharge pipe at the bottom, and is used to prepare filling slurry. [0003] The sand silo uses the weight of the tailing mortar to settle and concentrate in it. Therefore, the concentration efficiency and degree of concentration of the mortar are low. For example, the concentration of the tailing mortar from the dressing plant is generally 15%-20%. The final concentration is 45%-50%, and the tailing mortar with a concentration of 45%-50% is not suitable for preparing filli...
