Water filtering device of horizontal type sand silo

Abstract

The invention provides a water filtering device of a horizontal type sand silo. The water filtering device comprises a water filtering channel, a water filtering plate and a water filtering gate, wherein the water filtering channel is formed on the side wall of the horizontal type sand silo and located at the bottom of one side of the horizontal type sand silo, and the side, close to the inner wall of the horizontal type sand silo, of the inner wall of the water filtering channel is fixedly provided with a stop frame; the water filtering plate is fixedly clamped with the stop frame; the waterfiltering gate is fixed on the inner wall of the horizontal type sand silo, and covers the surface of one side, facing the inner portion of the sand silo, of the water filtering plate movably in the perpendicular direction; when the horizontal type sand silo is used for storing dried tailings, the water filtering gate is closed; when the horizontal type sand silo is used for storing tailing slurry, the water filtering gate is opened, the water in the tailing slurry is discharged from the water filtering channel through the water filtering plate, so that the structure is simplified and easy torealize, the horizontal type sand silo can meet the storing requirements of the dried tailings and tailing slurry simultaneously, the concentration of filling slurry is increased, and a filter screencan be cleaned in real time without repeated detachment.

Description

technical field [0001] The invention relates to the technical field of mining tailings mortar filling, in particular to a horizontal sand bin water filter device. Background technique [0002] In the common mining process, it is necessary to support the surrounding rock in the underground of the mine through filling. This process is to add water to the filling aggregate to make a mortar with a certain mass concentration, and then use pipelines, chutes or drilling to mix the mortar with It is transported to the underground filling position by gravity. The mortar on the construction site generally includes low-concentration tailing mortar transported by hydraulic power and dry tailing sand transported by vehicles according to its transportation mode. Under the existing technology, vertical sand bins are used for storage and concentration of tailing mortar transported by hydraulic power, while For dry tailings transported by vehicles, horizontal sand bins are used for storage....

Problems solved by technology

[0006] 2), when the horizontal sand bin water filter device is used to store the tailing mortar, there is no effective means to prevent excessive drainage, so that after the concentration of the tailing mortar stored in it reaches the filling requirement, due to the existence of the metal filter screen, it still remains It will cause the water in the tailing mortar to continue to lose, making it difficult for this kind of horizontal sand bin water filter device to meet the requirements for storing tailing mortar;

[0007] 3) In the above-mentioned horizontal sand bin water filter device, the closed steel plate and the fixed filter screen pass through the steel plate to protect the metal filter screen. This connection and fixing method is relatively cumbersome, and the water filter device is used to fix the steel plate It is fixed by a wedge-shaped wooden block arranged between the stop flange and the wedge-shaped wooden block, which is prone to rot or even failure due to the long-term drainage and filtration in a humid environment, which will eventually lead to the leakage of the stored tailing mortar
