Description

Technical Field

[0001] This utility model belongs to the technical field of mining auxiliary devices, and in particular, it is a device for preparing mine filling materials. Background Technology

[0002] In mining engineering, as roadways are excavated, the surrounding rock is prone to collapse or collapse, causing safety accidents. To prevent safety accidents, tailings or waste ore are usually used to fill the goaf. Fly ash is a common filling material. Fly ash is usually in a granular state and cannot be directly used for filling. Therefore, it is necessary to mix fly ash with other cementing materials to form a filling material. The solidification and hardening properties of the cementing materials are used to fill the goaf with the filling material containing fly ash. Therefore, the filling material needs to be prepared by mixing in advance.

[0003] In the prior art, patent document with publication number "CN214577177U" discloses a high-concentration cemented backfilling system for overflow tailings, including a filter press, a tailings dispersing and metering device, a storage device, a stirring device, and a trailer pump. The filter press is used to deeply dewater the high-concentration tailings slurry thickened by the thickener to prepare tailings filter cake. The tailings dispersing and metering device is used to disperse the tailings filter cake. The storage device is used to hold cementitious materials, water, and dispersed tailings. The stirring device is used to stir and activate the tailings, cementitious materials, and water after being metered by the storage device. The trailer pump is used to pump the high-concentration cemented backfill slurry to the area to be filled. Using this patented technical solution, the filter cake is first dispersed and then stirred and activated by the stirring device, achieving deep dewatering of the overflow tailings, increasing the concentration of the high-concentration cemented backfill slurry. The prepared high-concentration cemented backfill slurry is uniform, has good fluidity, and small concentration fluctuations, which is beneficial for slurry transportation and improves the stability of the backfill body formed after hardening.

[0004] However, in the existing technology, the mixing tank is usually placed on the ground, and the filling material delivery pipe is generally a flexible hose that can be twisted or bent. The filling material usually needs to be delivered in an upward direction. During the delivery process, the filling material constantly hits the inner wall of the delivery pipe, making the delivery pipe very easy to twist and shift, and may also cause nearby people to trip, posing a great safety risk.
