Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of the modification machine, and particularly relates to a novel stirring blade of modification machine. BACKGROUND

[0002] The stirring blade in the ore pulp modification machine can scrub the surface of particles under high shear conditions to effectively remove the oxidation layer or high-ash fine sludge on the surface of the particles, form a fresh surface, facilitate the full adsorption of the flotation reagent, thereby reducing the dosage of the flotation reagent and improving the flotation efficiency and processing capacity.

[0003] At present, the stirring blade of the ore pulp modification machine is generally a traditional stirring blade, and the scrubbing capacity needs to be improved, especially the friction and kneading of the fine particles are not enough, and many fine particles are wasted, so how to improve the scrubbing capacity of the fine particles is the research and development direction, that is, further improving the shear capacity is the research and development direction. CONTENT OF THE UTILITY MODEL

[0004] The utility model provides a novel stirring blade of modification machine, which can solve the problems in the background art.

[0005] A novel stirring blade of modification machine, comprising a paddle and a plurality of vertical paddle teeth arranged on the paddle, wherein the vertical paddle teeth have at least one shear angle, at least one side of the shear angle has a guide shear surface, and the guide shear surface is used for scrubbing and material guiding to increase the scrubbing probability of the material and other vertical paddle teeth.

[0006] Preferably, the paddle has a plurality of vertical paddle teeth arranged at the same center, the center points of all the vertical paddle teeth on the same circle are located on the same rotation circle, and the cross section of the vertical paddle teeth is a rectangle, and the connecting line of the diagonal lines is tangent to the rotation circle where the center point is located.

[0007] Preferably, the cross section of the vertical paddle teeth is a square.

[0008] Preferably, the plurality of vertical paddle teeth are arranged at equal arc distances.

[0009] Preferably, the upper and lower surfaces of the paddle are each provided with a plurality of vertical paddle teeth.

[0010] Beneficial effects: The novel stirring blade of modification machine can greatly improve the shear capacity and scrubbing capacity of the product, especially the scrubbing capacity of fine particles, and improve the flotation efficiency and recovery capacity. BRIEF DESCRIPTION OF DRAWINGS

[0012] Fig. 2The utility model discloses a structure schematic view,

[0013] Mark explanation:

[0014] Mark in drawing: paddle blade 1 vertical paddle tooth 2 shear angle 3 guide shearing surface 4. Specific embodiments

[0015] Below, one specific embodiment of the utility model is described in detail in combination with the drawings, but it should be understood that the protection scope of the utility model is not limited by the specific embodiment.

[0016] Example 1:

[0017] As Figs. 1-2 The utility model discloses a novel stirring blade of upgrader, including paddle blade 1 and the several vertical paddle tooth 2 of setting on paddle blade 1, vertical paddle tooth 2 has at least one shear angle 3, at least one side of shear angle 3 has guide shearing surface 4, and guide shearing surface 4 is used for scrubbing and material guide, to increase the scrubbing probability of material and other vertical paddle tooth 2.

[0018] Specifically, paddle blade 1 has several vertical paddle teeth 2 arranged around the same center, the center points of all vertical paddle teeth 2 on the same circle are on the same rotation circle, the cross section of vertical paddle tooth 2 is rectangular, the connecting line of the diagonal of the cross section is tangent to the rotation circle where the center point is located, the cross section of vertical paddle tooth 2 is preferably square, and the several vertical paddle teeth 2 can be arranged at equal arc distances.

[0019] Through the design that the connecting line of the diagonal of vertical paddle tooth 2 is tangent to the rotation circle where the center point is located, it can be ensured that the shear angle 3 of vertical paddle tooth 2 is always perpendicular to the shearing surface of the material during rotation shearing, and the material is sheared like a sharp blade during rotation, and the particles are scrubbed through the guide shearing surfaces 4 on both sides, and the material is guided to the other vertical paddle teeth 2 on both sides or one side, so as to increase the scrubbing probability of the particles in the material and the other vertical paddle teeth 2, improve the shearing and scrubbing effect, and especially improve the shearing and scrubbing effect on fine particles.

[0020] In some embodiments, the upper and lower surfaces of paddle blade 1 are each provided with several vertical paddle teeth 2 arranged around the same center.

[0021] The above disclosure is only a few specific embodiments of the utility model, but the utility model embodiments are not limited to this, and any changes that can be thought of by those skilled in the art should fall within the protection scope of the utility model.
