Description
Technical Field
[0001] The utility model belongs to the technical field of mining equipment, in particular to a continuous horizontal filling material mixer. Background Art
[0002] As mining paste filling technology becomes increasingly mature, filling stations are widely used in the mining industry. As one of the core components of a filling station, the filler mixer has a significant impact on the properties of the mixed filler.
[0003] Currently, paste filling technology for coal mines and metal mines uses different filling process routes. Coal mines primarily use crushed coal gangue as the filler, while most metal mines use metal tailings as the filler. The two processes employ different mixing methods. The former often uses two continuous horizontal mixers, while the latter mostly uses vertical mixers. This results in a variety of mixers in the filling station, a large equipment footprint, and high costs.
[0004] Existing filling material mixers generally use continuous twin-shaft forced mixers, which offer continuous feeding, mixing, and discharging. Because mixing time is primarily determined by the mixer's length and speed, a given continuous mixer design can suffer from short mixing times and difficulty in controlling them. This results in poor mixing uniformity in the finished filling material and poor adaptability to a variety of materials.
[0005] In order to solve the above problems, manufacturers must extend the mixing time of the materials in the mixing tank to improve their uniformity. There are two main methods currently adopted: one is to extend the length of the mixer and increase the overall structural size to achieve this, but the disadvantage is that it not only causes material waste but also increases the equipment footprint. At the same time, in order to ensure that the stiffness of the mixing shaft meets the requirements, the existing technology often uses two mixers and adopts graded mixing, which increases the cost; another improvement measure is to achieve it by reducing the mixing speed, so that the axial mixing speed of the material slows down, changing the movement characteristics of the material, and achieving the effect of extending the mixing time, but the disadvantage is that it also weakens the movement of the mixing in the circumferential direction, weakens the throwing effect, and reduces the interaction between the two mixing shafts, which still cannot achieve fast and uniform mixing.
[0006] Conventional mixers, due to the high fluidity of the filler, cannot form a pool at the bottom of the mixing tank. As a result, the material does not have time to be fully mixed by the mixing blades and is quickly discharged from the discharge port, resulting in poor mixing effect. Even with a pool, after the mixer stops working, the waste material cannot be completely discharged from the mixing tank in time, causing the material to clump and make cleaning difficult.
