Description

Technical Field

[0001] The utility model relates to the technical field of stone particle sorting, in particular to a material distribution mechanism used for stone particle sorting and dust removal equipment. Background Art

[0002] When the stone is crushed into stone particles, there is a lot of stone powder / dust, which needs to be sorted by dust removal equipment. In the sorting process, a conveying mechanism is usually built to feed the material from the top of the dust removal equipment; a conical hopper is set at the top of the dust removal equipment to convey the material into the conical hopper.

[0003] The stone separation and dust removal means to blow away the dust in the stone and keep the useful stone. In order to blow away the dust more fully, it is necessary to evenly disperse the mixture of stone and dust first, and then use a fan to blow away the dust. In the prior art, only one impeller is used. When the material falls on the impeller, the material is dispersed circumferentially under the action of the rotation of the impeller. However, the dispersion effect of this dispersion method is not particularly ideal.

[0004] Based on various situations reported by customers, our company designed new sorting and dust removal equipment. In order to fully protect the entire equipment, it was divided into multiple patented solutions. This solution only protects the material distribution area. Utility Model Content

[0005] The utility model aims to overcome the shortcomings of the prior art and provide a material distribution mechanism for stone particle sorting and dust removal equipment, which has good dispersion effect, is conducive to subsequent better dust removal and has a simple structure.

[0006] The purpose of the utility model is achieved through the following technical solutions: a material distribution mechanism for stone material sorting and dust removal equipment, a conical hopper is arranged on the top of the stone material sorting and dust removal equipment, and a material distribution mechanism is arranged below the conical hopper;

[0007] The material distribution mechanism includes a rotating drum, a plurality of ribs, and an impeller;

[0008] The rotating drum is arranged at the material inlet of the conical hopper, and an impeller is arranged directly below the rotating drum. The impeller is connected to the lower edge of the rotating drum through a plurality of ribs, so that the plurality of ribs form an inverted cone shape similar to scattered bones, and a conical cavity is surrounded by the plurality of ribs, and there is a spacing between adjacent ribs;

[0009] The material leaking from the conical hopper first falls into the conical cavity surrounded by multiple ribs, and then disperses from the gaps between adjacent ribs; the dispersed material contacts the impeller, and the impeller disperses the corresponding material again, thereby dispersing the material circumferentially, and subsequently the dust can be better blown away by the action of the fan.

[0010] As a preferred technical solution of the present application, a conical protrusion is provided on the upper surface of the impeller, and the conical protrusion is located at the bottom of the conical cavity surrounded by multiple ribs; when the material falls on the bottom of the conical cavity surrounded by multiple ribs, the material falls on the conical protrusion, allowing the material to be better dispersed.

[0011] Alternatively, as a preferred technical solution of the present application, a column A capable of vertical elastic expansion and contraction is installed on the impeller, and the top of the column A has a conical protrusion; under the action of the column A, the conical protrusion is close to the discharge port of the conical hopper, reducing the discharge amount of the discharge port of the conical hopper, forming a structure to prevent a large amount of material from falling; in addition, when the material in the conical hopper falls on the conical protrusion, the material can be dispersed.

[0012] As a preferred technical solution of the present application, the lower end of the column A passes through the center of the impeller, and the lower end of the column A rests against the bearing plate via a spring, and the bearing plate is fixed to the impeller via a screw, forming a vertical elastic mounting structure of the column A.

[0013] As the preferred technical solution of the present application, a connecting cylinder is fixed at the discharge port of the conical hopper, an auxiliary cylinder is fixed on the connecting cylinder, and a rotating cylinder is provided outside the auxiliary cylinder through a corresponding ball sleeve; the rotating cylinder rotates around the auxiliary cylinder through the corresponding ball, and the rotating cylinder is connected to the material distribution motor drive through a belt.

[0014] As a preferred technical solution of the present application, the vertical cross-section of the auxiliary cylinder is L-shaped, and the vertical cross-section of the rotating cylinder is inverted L-shaped, and the two are interlocked with each other; a pressing cylinder is also sleeved outside the auxiliary cylinder, and the pressing cylinder is pressed on the upper surface of the rotating cylinder through ball A; balls B are provided on the interlocking surfaces of the auxiliary cylinder and the rotating cylinder, and the inner wall of the rotating cylinder is pressed against the cylindrical surface of the auxiliary cylinder through ball C.

[0015] As the preferred technical solution of the present application, the multiple blades of the impeller form overlapping areas between adjacent blades when viewed from a top view. If there is a large gap between adjacent blades, the stone particles are likely to fall through the gap, thus failing to separate the materials well. In this solution, the overlapping areas formed by the multiple blades can prevent the materials from falling directly, allowing the materials to be better acted upon by the impeller, thereby achieving good separation.

[0016] For ease of understanding, the core design points and principles of this solution are explained:

[0017] It should be noted that the stone sorting and dust removal refers to blowing away the dust in the stone and retaining the useful stone. In order to blow away the dust more fully, it is necessary to evenly disperse the mixture of stone and dust first, and then use a fan to blow away the dust. In the prior art, only one impeller is used. When the material falls on the impeller, the material is dispersed circumferentially under the action of the rotation of the impeller. However, the dispersion effect of this dispersion method is not particularly ideal.

[0018] The working principle of this scheme is as follows: a. The material falling from the conical hopper falls into the conical cavity formed by multiple ribs, and the material contacts the upper surface of the conical protrusion, splashing in the circumferential direction, realizing the first circumferential dispersion of the material in the conical cavity; b. The material dispersed in the conical cavity for the first time is discharged from the spacing between adjacent ribs, realizing the second circumferential dispersion of the material (under the shielding effect of the ribs, a large amount of material cannot be discharged from a certain position); c. The material dispersed in the second circumferential direction falls on the impeller, and under the action of the impeller, the material is dispersed for the third time;

[0019] After the three times of good circumferential dispersion of the material, the dust in the material can be better removed by the fan.

[0020] The utility model has the following advantages:

[0021] (1) Good dispersion effect, which is conducive to better dust removal in the future;

[0022] The conical protrusions allow the material to be dispersed circumferentially in the conical cavity for the first time, and the material in the conical cavity is dispersed circumferentially between the rib spacings to achieve the second circumferential dispersion; the material discharged from the rib spacing is dispersed for the third time under the action of the impeller; after the three dispersions, the dispersion effect is excellent, which is conducive to better dust removal in the future;

[0023] (2) Simple structure;

[0024] Only a rotatable drum and an impeller are provided, and the impeller is connected to the drum through a plurality of ribs, a conical cavity is formed between the plurality of ribs, and a conical protrusion is provided in the conical cavity; the whole structure is very simple, and the three-fold dispersion of the material can be realized.

[0036] (Example 1)

[0037] See also Figure 1-Figure 3 , a material distribution mechanism for a stone material sorting and dust removal device, a conical hopper 10 is arranged on the top of the stone material sorting and dust removal device, and a material distribution mechanism is arranged below the conical hopper 10, and the material distribution mechanism includes a rotating drum 50, a plurality of ribs 60, and an impeller 70;

[0038] The drum 50 is arranged at the material inlet of the conical hopper 10, and an impeller 70 is arranged directly below the drum 50. The impeller 70 is connected to the lower edge of the drum 50 via a plurality of ribs 60, so that the plurality of ribs 60 form an inverted cone shape similar to scattered bones, and a conical cavity is surrounded by the plurality of ribs 60, and there is a spacing between adjacent ribs 60;

[0039] In addition, a conical protrusion 80 is provided on the upper surface of the impeller 70, and the conical protrusion 80 is located at the bottom of the conical cavity surrounded by the plurality of ribs 60;

[0040] During operation: a. The material leaking from the conical hopper 10 will first fall into the conical cavity surrounded by multiple ribs 60, and the fallen material will interact with the conical protrusion 80. Under the action of the conical protrusion 80, the material will be dispersed in the circumferential direction to achieve the first material distribution; b. The material after the first dispersion will flow out and disperse from the spacing gaps between adjacent ribs 60 (by designing the density of the ribs 60, a large amount of material can be avoided from flowing out from certain spacing gaps), so the second material distribution is achieved through the ribs 60; b. The material after the second dispersion contacts the impeller 70, and under the action of the low-speed impeller 70, the material is thrown out by the impeller 70 to complete the third material distribution; through three material distributions, the material can be better dispersed in the circumferential direction - avoiding concentration in the center, which is conducive to the subsequent blowing away of dust in the dispersed material under the action of the fan.

[0041] See also Figure 3 A connecting cylinder 51 is fixed at the discharge port of the conical hopper 10, an auxiliary cylinder 52 is fixed on the connecting cylinder 51, and a rotating cylinder 50 is sleeved on the outside of the auxiliary cylinder 52 through corresponding balls; and the vertical section of the auxiliary cylinder 52 is L-shaped, and the vertical section of the rotating cylinder 50 is inverted L-shaped, and the two are interlocked; a pressing cylinder 53 is sleeved on the outside of the auxiliary cylinder 52, and the pressing cylinder 53 is pressed on the upper surface of the rotating cylinder 50 through the ball A; the auxiliary cylinder 52 and the rotating cylinder 50 are provided with balls B at the mutually interlocking surfaces, and the inner side wall of the rotating cylinder 50 is pressed against the cylindrical surface of the auxiliary cylinder 52 through the ball C. When working, the rotating cylinder 50 rotates around the auxiliary cylinder 50 through the corresponding balls, and the rotating cylinder 50 is connected to the material distribution motor 90 through a belt.

If there is a large gap between adjacent blades, the stone particles are likely to fall through the gap, thereby failing to separate the materials well. In this solution, the overlapping area formed by multiple blades can prevent the materials from falling directly, allowing the materials to be better acted upon by the impeller and thus achieving good separation.

[0043] (Example 2)

[0044] The material distribution mechanism used in the stone material sorting and dust removal equipment has an improved arrangement of the conical protrusion 80 based on the first embodiment.
