Description

Technical Field

[0001] This utility model relates to the field of material dispersing and separating machines, and in particular to a multi-shaft material dispersing and separating machine for mineral processing tailings. Background Technology

[0002] With the increasing depletion of surface and shallow mineral resources, mining activities are gradually shifting to deeper levels, leading to a series of geological disasters such as surface subsidence, tailings dumping, and solid waste hazards. Reusing mining tailings and backfilling mined-out areas are effective means to address these problems.

[0003] Tailings from mineral processing plants, as waste products after mineral processing, not only occupy space resources but also pose certain environmental hazards. However, the remediation of mined-out areas requires a large amount of tailings as backfill material. Therefore, most backfilling sections adopt a "self-production and self-use" model, using tailings from the processing plant mixed with cement and other binding materials and water to backfill the mined-out areas. Generally, tailings from the processing plant are directly transported via pipeline to large storage facilities such as sand silos in the backfilling section. If production and backfilling efficiency are not synchronized, a large amount of tailings will accumulate. The processing plant will then dehydrate and stockpile the tailings in a warehouse for later use. For subsequent use, a dispersing and separating machine is needed to break up the clumps of tailings and send them to a mixing tank for mixing.

[0004] Conventional material dispersers are mostly triaxial mixers – one shaft above and two shafts below. However, for tailings with high moisture content, tailings often stick to the walls and the discharge port becomes clogged during dispersion. The root cause lies in the limitations of the mixing direction and layout of the mixing shafts.

[0005] Therefore, this application designs a multi-shaft dispersing and distributing machine for mineral processing tailings, and solves the above-mentioned problems. Summary of the Invention

[0006] To overcome the shortcomings of the existing technology, this utility model provides a multi-shaft dispersing and distributing machine for mineral processing tailings.

[0007] A multi-shaft dispersing and distributing machine for mineral processing tailings, comprising a storage silo, characterized in that:

[0008] The storage silo has a trapezoidal structure that is wider at the top and narrower at the bottom, which facilitates the centralized treatment of tailings. A stirring shaft is arranged in the storage silo, and the stirring shaft adopts a double-layer multi-shaft spacing arrangement of two shafts at the top and two shafts at the bottom. Each stirring shaft is controlled by a separate power unit, and a conveyor belt is installed at the bottom outlet of the storage silo.

[0009] Furthermore, in order to better realize this utility model, a vibrator is installed on the trapezoidal wall of the storage silo.

[0010] Furthermore, in order to better realize this utility model, the inside of the storage silo is equipped with a polymer wear-resistant plate, which effectively prevents the tailings from sticking to the silo wall and facilitates the discharge of the tailings.

[0011] Furthermore, in order to better realize this utility model, the power device control includes two primary power devices and two secondary power devices. The primary power devices are driven and connected to the bottom agitator shaft, and the secondary power devices are driven and connected to the top agitator shaft.

[0012] The beneficial effects of this utility model are:

[0013] The material dispersing machine of this invention can avoid the situation of tailings sticking to the wall and the discharge port accumulating and blocking during use. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0021] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0022] Figures 1-4 This is a specific embodiment of the present utility model, which is a multi-shaft dispersing and distributing machine for mineral processing tailings. The inner wall of the storage bin 1 is covered with a high-polymer wear-resistant plate 7, and the outer wall is equipped with a vibrator 9, which helps to improve the tailings discharge speed and avoid clogging the discharge port.

[0023] The agitator 6, supported by bearing housing 8, is connected to the primary power unit 2 and the secondary power unit 5 and is arranged inside the storage silo. It employs a double-layer, multi-shaft clearance arrangement with two shafts on top and two on the bottom. The rotation direction of the agitator 6 is as follows: Figure 2 As shown.

[0024] After the tailings are loaded into storage bin 1 by a loader or other transportation equipment, the primary power unit 2 and the secondary power unit 5 are started, and the tailings are discharged in an "S" shape within storage bin 1. Figure 2 This design facilitates repeated dispersing of tailings, unlike traditional dispersers which result in uneven dispersion and material accumulation at the discharge port. After the tailings fall into the conveyor belt 3, the conveyor belt 3 is driven by the transmission motor 4 to transport the tailings to the next process until the tailings are emptied and the next working cycle begins.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
