Description

Technical Field

[0001] This utility model belongs to the field of quality modification machine technology, and specifically relates to a novel 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

Detailed Implementation

[0026] 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.

[0027] Example 1:

[0028] like Figure 1 As shown in the figure, the present invention provides a novel modifier, including a modifier body, which 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 disposed inside the through hole 4. The stirring blades 32 are correspondingly disposed to the through hole 4. The stirring blades 32 stir and shear the material passing through the through hole 4. The material is blocked by the baffle 2, which can prolong its residence time in each area, increase its stirring time, and increase the probability of shearing and scrubbing with the stirring assembly, thereby improving the shearing capacity. In addition, the through hole 4 is provided at the center of the baffle 2, and stirring blades 32 are disposed inside the through hole 4. This design structure requires all materials to pass through the through hole 4, that is, to be stirred by the stirring blades 32, which greatly increases the probability of shearing and scrubbing with the stirring blades 32, thereby further improving the shearing capacity. In the existing structure, several small holes are provided on the baffle 2. This structure cannot guarantee that the material must be stirred by the stirring blades 32.

[0029] Example 2:

[0030] like Figure 2-4 As shown, the stirring blade 32 includes a blade 321 and a plurality of vertical blade teeth 322 disposed on the blade 321. Each vertical blade tooth 322 has two 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.

[0031] 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.

[0032] 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.

[0033] Example 3:

[0034] like Figure 1 As shown, the diameter of the through hole 4 is larger than the stirring diameter of the stirring blade 32. The inner wall of the through hole 4 has a circumferential array of first toothed blades 5. The first toothed blades 5 have a toothed structure on the side near the stirring blade 32 to improve the shearing effect.

[0035] In some embodiments, the upper and lower sides of the baffle 2 are provided with a plurality of second toothed blades 6, and the shearing effect is improved by providing the second toothed blades 6.

[0036] Example 4:

[0037] like Figure 1-2 As shown, a third toothed blade 7 is provided above the stirring blade 32. The third toothed blade 7 is connected to the stirring shaft 31. The third toothed blade 7 is provided to increase the radial flow, that is, to improve the radial flow of each shearing area, so as to improve the shearing effect. The blade has a toothed structure, which can further improve the shearing effect.

[0038] Example 5:

[0039] like Figure 1 as well as Figure 5-6 As shown, the inner wall of the cylinder 1 is equipped with a circumferential array of inclined baffles 8. The inclined baffles 8 are used to guide the material to the central area. The angle between the inclined baffles 8 and the radial direction of the cylinder 1 is preferably between 30 and 60 degrees. At least one side of the inclined baffles 8 is provided with shearing teeth 81. It is best to provide shearing teeth 81 on the side of the inclined baffles 8 closest to the cylinder 1, so as to avoid forming a dead angle with the inner wall of the cylinder 1, that is, the material flows through the gaps of the shearing teeth 81. Alternatively, shearing teeth 81 can be provided on both sides to improve the shearing effect.

[0040] In existing technologies, toothed plates are also set on the inner wall of the cylinder 1 to improve shearing capacity. However, they are generally set perpendicular to the inner wall of the cylinder 1 and cannot effectively guide the material to the stirring component at the center.

[0041] 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.
