[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] like Figure 1-3 As shown, a tailings mixing and feeding processing equipment includes a feeding hopper 1, inside of which are arranged in sequence along the falling direction:

[0028] Receive bucket 2;

[0029] The special-shaped portion 3 includes a protrusion 31 extending upward from the discharge opening of the receiving bucket 2 and maintaining a predetermined distance from the discharge opening;

[0030] Spiral flow guides 4 are provided at the edge of the special-shaped portion 3 and arranged in a circular array;

[0031] A discharge trough 5 , the inlet of which is communicated with the discharge ports of the plurality of spiral flow guide members 4 .

[0032] In the above technology, the material enters the receiving bucket 2, and under the guidance of the special-shaped portion 3, enters the spiral guide member 4 so as to achieve the purpose of mixing when passing through, and then is collected and discharged through the discharge chute 5.

[0033] As an embodiment further provided by the utility model, a recessed portion 32 is provided at the edge of the special-shaped portion 3, a convex edge 41 is provided on the feed port of the spiral guide member 4, and the convex edge 41, the recessed portion 32 and the receiving bucket 2 newly form a material collecting cavity 6; and a narrow flow inlet 7 is formed between the end of the convex edge 41 and the inner wall of the recessed portion 32.

[0034] Specifically, when the material is guided by the protrusion 31 and then passes through the narrow flow inlet 7 , the flow velocity is reduced to form a relatively closed space. When the material flows through the spiral guide 4 , it will form a vortex in the material collection chamber 6 .

[0035] As another embodiment further provided by the present invention, an elliptical flow circulator 8 is centrally arranged in the discharge trough 5. The cavity formed between the flow circulator 8 and the discharge trough 5 has a conical cross-section, and its narrow opening faces the discharge port of the discharge trough 5.

[0036] As another embodiment further provided by the utility model, an arch cover 10 is arranged in the receiving bucket 2, and the arc top of the arch cover 10 is connected to the outlet of the discharge chute 5.

[0037] As another embodiment further provided by the present invention, the spiral guide member 4 is specifically an arc-shaped structure, and a spiral member 42 is provided on the inner wall thereof.

[0038] The center of the spiral member 42 is a through hole, and the structure is consistent with the spiral guide member 4;

[0039] It also includes a tapered column 9 extending from the through hole to the material collecting cavity 6 , and a spiral groove 91 is formed on the tapered column 9 .

[0040] Furthermore, the spiral groove 91 and the spiral member 42 have opposite spiral directions.

[0041] Specifically, the material in the embodiment forms a vortex when entering the material collecting chamber 6 and passing through the spiral member 42, and forms a reverse spiral under the guidance of the spiral groove 91 during the flow process, and the two form turbulent flow, thereby optimizing the mixing effect.

[0042] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
