Description

Technical Field

[0001] The invention relates to the technical field of tailings processing equipment, and in particular to a mixing device for fine-particle slurry materials and a use method thereof. Background Art

[0002] Since tailings have become the largest output and the largest stockpile of solid waste in my country, in order to reasonably handle and utilize tailings, it is now a new way to utilize tailings resources by using fine tailings of -200 mesh and below to prepare concrete composite admixtures, high-strength and high-performance grouting materials, dry mortar, decorative mortar, ancient building repair mortar and other high-value-added products. Concrete composite admixtures have become an indispensable component of high-performance concrete.

[0003] The fluidity, expansion rate, compressive strength and flexural strength of high-performance cement-based grouting materials prepared with fine-grained iron tailings powder all meet the requirements of the specifications. However, in the preparation of high-performance cement-based grouting materials, the fine-grained iron tailings powder needs to be mixed, so that the materials are mixed together in a certain ratio to make them meet the requirements of the materials for preparing high-performance cement-based grouting materials. When mixing mineral powders, most of the existing equipment piles them together and then reverses them for mixing. This mixing method is prone to dead corners that cannot be mixed, causing some materials to pile up together and cannot be mixed with other materials.

[0004] Therefore, we have made improvements on this and proposed a mixing device for fine particle slurry material and a method of using the same. Summary of the invention

This mixing method is prone to dead corners where mixing cannot occur, resulting in some materials piling up together and unable to be mixed with other materials.

When the fine-grained tailings material comes down from the inside of the barrel, it is discharged through the discharge pipe. The two symmetrically arranged discharge pipes cross-mix the two materials together. Then, the motor 1 drives the mixing roller to rotate relative to each other to make the materials together and then output them to the bottom side. The motor 4 drives the mixing roller to put the mixed materials together inside the mixing chamber for mixing again. The motor 2 drives the material plate to open and let the materials fall down.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them.

Such terms are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0031] As described in the background technology, when existing equipment mixes mineral powder, most of them pile it together and then reverse it for mixing. This mixing method is prone to dead corners where some materials cannot be mixed, resulting in the problem that some materials are piled together and cannot be mixed with other materials.

[0032] In order to solve this technical problem, the present invention provides a mixing device for fine-particle slurry material and a method for using the same.

Then, the materials are output to the bottom side after the mixing pieces rotate relative to each other to mix the materials together. The materials are then mixed by the mixing roller 141 on the bottom side, so that they can be cross-mixed at the same time when and after the materials are discharged, thereby increasing the uniformity of the mixing and reducing the inability to mix the materials together due to dead corners.

[0035] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

The mixing piece includes a motor 11, and a mixing roller 111 is connected to the output end of the motor 11.

[0040] During the implementation process, an external feeding device enters the interior of the barrel 2, opens the channel through the switch valve 21 and falls. When the fine-grained tailings material comes down from the interior of the barrel 2, it is output through the discharge pipe 22. The two symmetrically arranged discharge pipes 22 cross-mix the two materials together, and then the motor 11 drives the mixing roller 111 to rotate relative to each other to mix the materials and then output them to the bottom side.

[0041] The implementation effect is to enable cross-mixing to be performed during and after material feeding, thereby increasing the uniformity of mixing and reducing the problem of materials not being mixed together due to dead corners.

[0048] During the implementation process, when output is required, the closed door 15 can be opened to release the materials in the storage chamber 18, or when a large amount of materials need to be mixed or stored, the motor 3 13 is started to drive the storage chamber 18 to rotate, and the movable plate 31 connected to the collection box 3 is driven to move to output the materials to the collection box 3 for placement.

[0049] The implementation effect is convenient for the later mixing of multiple materials or the storage of large amounts of mixed materials.

[0050] During operation, the external feeding device enters the interior of the barrel 2, opens the channel through the switch valve 21 to fall, and when the fine-grained tailings material comes down from the inside of the barrel 2, it is output through the discharge pipe 22. The two symmetrically arranged discharge pipes 22 cross-mix the two materials together, and then the motor 11 drives the mixing roller 111 to rotate relative to each other to make the materials together and then output them to the bottom side. The motor 4 14 drives the mixing roller 141 to put the mixed materials together in the mixing chamber 17 for mixing again, and the motor 2 12 drives the material plate 121 to open and let the materials fall out. The motor 4 14 drives the mixing roller 141 to put the mixed materials together in the mixing chamber 17 for mixing again, and the motor 2 12 drives the material plate 121 to open and let the materials fall out.
