Description

Technical Field

[0001] This utility model belongs to the field of quality modification machine technology, and specifically relates to a high-scrubbing quality modification machine. Background Technology

[0002] The stirring blades in the slurry modifier can scrub the particle surface under high shear conditions to effectively remove the oxide layer or high-ash fine mud on the particle surface, forming a fresh surface that facilitates the full adsorption of flotation reagents, thereby reducing the amount of flotation reagents used and improving flotation efficiency and processing capacity.

[0003] CN208177396U discloses a high-efficiency mineral slurry reformer, which includes a mixing tank. The right side of the mixing tank is connected to a general mixing tank via a bottom connecting pipe. Inside the mixing tank, a drive motor is located at the top, connected to a gearbox below. A drive shaft extends from the bottom of the gearbox directly into the mixing tank. Multiple stirring groups are arranged from top to bottom on the drive shaft, each stirring group having a baffle plate fixed below it. A discharge port is located on the front side of the mixing tank, facing forward. This invention, through the above design, mixes reagents and mineral powder within the mixing tank. After being sprayed with high-pressure liquid, the liquid enters the mixing tank from the bottom, where it is stirred from bottom to top by at least three stirring groups to ensure thorough mixing of the reagents and mineral powder.

[0004] Although it also has a baffle structure, which can provide some barrier and increase the flow time of materials in the mixing tank, it does not significantly improve the shear force, especially for the friction and kneading of fine particles.

[0005] In addition, the mixing blades of the current slurry modifier are generally traditional mixing blades, and their scrubbing ability needs to be improved, especially for the friction and kneading of fine particles, which is insufficient, resulting in the waste of many fine particles. How to improve the scrubbing ability of fine particles is our research and development direction, that is, to further improve the shearing ability. Utility Model Content

[0023] The following describes a specific embodiment of the present invention in detail with reference to the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.

[0024] Example 1:

[0025] like Figure 1 As shown in the figure, this utility model provides a high-efficiency scrubbing and conditioning machine, including a conditioning machine body. The conditioning machine body includes a cylinder 1, a stirring assembly, and at least one baffle 2 disposed inside the cylinder 1. The stirring assembly includes a stirring shaft 31 and at least one set of stirring blades 32. A through hole 4 is provided at the center of the baffle 2, and stirring blades 32 are provided on at least one side above and below the through hole 4. The stirring blades 32 are correspondingly arranged with the through hole 4. The stirring blades 32 stir and shear the material passing through the through hole 4. The stirring diameter of the stirring blades 32 should preferably be greater than or equal to the diameter of the through hole 4. The material is blocked by the baffle 2. To extend the residence time in each area, the mixing time can be increased and the probability of shearing and scrubbing with the mixing components can be improved, thereby enhancing the shearing capacity. In addition, a through hole 4 is provided at the center of the baffle 2, and a mixing blade 32 is provided on at least one side above and below the through hole 4. This design structure ensures that all materials must pass through the through hole 4, that is, they must be mixed by the mixing blade 32, which greatly increases the probability of shearing and scrubbing with the mixing blade 32, thereby further improving the shearing capacity. In the existing structure, several small holes are provided on the baffle 2, which cannot guarantee that the materials must be mixed by the mixing blade 32.

[0026] The baffle 2 has several toothed blades 5 on at least one side, to improve the shearing and scrubbing effect.

[0027] Example 2:

[0028] The stirring blade 32 includes a blade 321 and a plurality of vertical blade teeth 322 disposed on the blade 321. The vertical blade teeth 322 have at least one shear angle 324. Both sides of the shear angle 324 have guide shear surfaces 323. The guide shear surfaces 323 are used for scrubbing and guiding the material to both sides to increase the probability of the material scrubbing with the other vertical blade teeth 322 on both sides or one side.

[0029] Specifically, the blade 321 has several vertical blade teeth 322 arranged in the same circle. It is best that several circles of vertical blade teeth 322 are provided on both the upper and lower surfaces of the blade 321. The center point of all the vertical blade teeth 322 on the same circle is on the same rotation circle. The cross-section of the vertical blade teeth 322 is rectangular, and the line connecting its diagonals is tangent to the rotation circle where its center point is located. The cross-section of the vertical blade teeth 322 is square. The several circles of vertical blade teeth 322 can be arranged with equal arc distance.

[0030] By designing the line connecting the diagonals of the vertical paddle teeth 322 to be tangent to the rotation circle containing its center point, it is ensured that the shearing angle of the vertical paddle teeth 322 is always perpendicular to the shearing surface of the material during the rotation shearing process. During the rotation, it shears the material like a sharp blade, and scrubs the particles through the guide shearing surfaces 3 on both sides. The guide shearing surfaces 3 on both sides guide the material to other vertical paddle teeth 322 on one side, thereby increasing the probability of the particles in the material being scrubbed by other vertical paddle teeth 322, improving the shearing and scrubbing effect, especially improving the shearing and scrubbing effect on fine particles.

[0031] Example 3:

[0032] like Figure 1 As shown, in order to facilitate the disassembly of the stirring assembly, the baffle 2 includes several unit sector plates 21, which are detachably connected to each other and detachably connected to the cylinder 1.

[0033] Specifically, the unit sector plate 21 is provided with a connecting plate 22, and the connecting plates 22 are connected by bolts to achieve a detachable connection. The edge of the unit sector plate 21 is provided with a connecting hole to achieve a detachable connection with the cylinder 1. The cylinder 1 can be provided with a connecting hole that matches the connecting hole.

[0034] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
