[0002] During the mining and processing of antimony ore, a large amount of tailings will be generated. Tailings are solid wastes left after the ore is processed by processes such as crushing, grinding and beneficiation. It is usually composed of fine particles and has a certain water content and viscosity. The traditional way of treating tailings is usually to discharge them directly into the tailings pond, which not only occupies a large amount of land resources, but also may cause pollution to the surrounding environment. With the enhancement of environmental awareness and the implementation of sustainable development strategies, how to reasonably and effectively treat antimony tailings has become an urgent problem to be solved.

[0003] In order to solve the above problems, backfilling technology came into being. Backfilling technology refers to the process of treating waste materials such as tailings to give them a certain fluidity and strength, and then filling them into underground goafs or open-pit mines to achieve the purpose of stabilizing the strata, reducing geological disasters, recycling resources and protecting the environment. During the backfilling process, tailings need to be mixed with cement and other cementitious materials to form a backfill with a certain strength.

[0004] However, the existing antimony tailings filling system often has problems such as uneven mixing, insufficient filling strength, and easy clogging of equipment when processing tailings. These problems not only affect the filling effect, but also increase the maintenance cost and operation difficulty of the equipment. Therefore, it is of great practical significance and market demand to develop a filling system that can efficiently and stably process antimony tailings. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model provides an antimony ore tailings filling system, such as Figure 1-Figure 3 As shown, it includes a desludging tank 1, a cement storage barrel 2 is arranged on one side of the desludging tank 1, a dust cleaning bin 3 is connected to the top of the cement storage barrel 2 for dust cleaning, a spiral discharger 4 is connected to the bottom side of the cement storage barrel 2, a discharge pipe 11 is connected to the bottom of the desludging tank 1, the end of the discharge pipe 11 is connected to the bottom of the cement storage barrel 2, a dust cleaning bin 3 is installed inside the dust cleaning bin 3, a connecting pipe 31 is arranged below the inside of the dust cleaning bin 3, and a sediment trough 34 is arranged on the outside of the connecting pipe 31 for collecting the particles that fall after being blocked by the dust filter 33.

[0023] In this embodiment, the bottom of the connecting pipe 31 is connected to the top air outlet pipe 25 of the cement storage barrel 2, and a baffle 32 is installed on the top of the connecting pipe 31 through a support column. A gap is set between the baffle 32 and the top of the connecting pipe 31 to facilitate gas discharge, and cement particles in the gas are blocked by the baffle 32.

[0024] Specifically, the bottom surface of the sediment trough 34 is inclined outward, and a slag discharge port 35 is provided on one side outer wall of the sediment trough 34 . A sealing plug is installed outside the slag discharge port 35 to facilitate the discharge of sediment.

[0025] Furthermore, a partition 23 is provided in the middle of the interior of the cement storage barrel 2, and the partition 23 divides the interior of the cement storage barrel 2 into two spaces. Both spaces are cylindrical structures. A rotating shaft 5 is installed in one space, and a spiral blade 51 is installed on the outer wall of the rotating shaft 5. The top of the rotating shaft 5 is driven to rotate by a driving motor 52. A plurality of inclined plates 24 are installed from top to bottom in the other space to facilitate the material to slide down and mix during the sliding process.

[0026] Furthermore, a feeding trough 21 is installed at an upper portion of one side of the cement storage barrel 2 , and a tailings inlet pipe 22 is installed at a lower portion of one side of the cement storage barrel 2 , and an outer end of the tailings inlet pipe 22 is connected to the discharge pipe 11 .

[0027] Furthermore, a stirring rod 6 is installed above the space of the inclined plate 24 , and a stirring blade 61 is installed on the outer wall of the stirring rod 6 .
