[0026] As Figure 1 and Figure 2 In this embodiment, the sorting device includes a sorting bed 10, a discharge structure 20, and an air supply structure. The sorting bed 10 has a feed end 11 and a discharge end 12. The discharge structure 20 is arranged on the sorting bed 10, and the discharge structure 20 includes a discharge passage 21 and a blocking piece 22. The inlet of the discharge passage 21 extends along the width direction of the sorting bed 10.

[0027] The technical scheme of the embodiment is applied, the material discharging structure 20 is arranged on the sorting bed 10, the material discharging structure 20 comprises a material discharging channel 21 and a blocking piece 22, the inlet of the material discharging channel 21 extends along the width direction of the sorting bed 10, the blocking piece 22 is arranged on the sorting bed 10 and located downstream of the inlet of the material discharging channel 21, the interior of the blocking piece 22 has a containing cavity 221, the bottom of the blocking piece 22 is provided with a plurality of first air outlets 222, and the first air outlets 222 are communicated between the containing cavity 221 and the material discharging channel 21. The air supply structure containing cavity 221 is communicated. Through the above arrangement, the mixture material enters into the sorting bed 10 from the feeding end 11 of the sorting bed 10 and moves towards the discharging end 12. The material discharging channel 21 can realize material discharging, the blocking piece 22 can block the lowest layer of the material after layering, so that the part of the material flow can avoid passing over the material discharging channel 21, the air supply structure blows air into the containing cavity 221 and is discharged through the plurality of first air outlets 222, and since the first air outlets 222 are communicated with the material discharging channel 21, the air flowing out through the first air outlets 222 can blow towards the material in the material discharging channel 21 and change the flow direction under the action of the material, that is, blow from the material discharging channel 21 to the inlet of the material discharging channel 21. In this way, on the one hand, the flow speed of the material can be accelerated, and on the other hand, the material can be driven to avoid material accumulation, thereby effectively improving the sorting effect. Therefore, the technical scheme of the embodiment effectively solves the problem of poor sorting effect of the sorting device in the related art.

[0028] Specifically, the above design enables the wind force to act more precisely on the material, improving the sorting efficiency, and is particularly suitable for the sorting of granular materials such as ores and coal, and can effectively improve the product quality in industrial production. By precisely controlling the distribution and size of the wind force, the sorting device can effectively separate granular materials of different densities and sizes, and improve the accuracy and efficiency of sorting.

[0029] As shown in Figures 1 to 3 In the embodiment, the blocking piece 22 comprises a first plate body 223 and a second plate body 224, the first end of the first plate body 223 is connected with the sorting bed 10, the second end of the first plate body 223 extends into the inlet of the material discharging channel 21, the second plate body 224 is connected with the second end of the first plate body 223 and extends upwards, and the plurality of first air outlets 222 are located on the first plate body 223. The above first plate body 223 provides a position for arranging the first air outlets 222, and the second plate body 224 can block the material. Meanwhile, the structure of the first plate body 223 and the second plate body 224 is simple and convenient for processing.

[0030] It should be noted that when the blocking piece 22 only comprises the first plate body 223 and the second plate body 224, the second plate body 224 is arc-shaped, and the two ends of the arc-shaped second plate body 224 are connected with the first plate body 223, that is, the containing cavity 221 is located between the first plate body 223 and the second plate body 224.

[0031] As Figures 1 to 3 shown in the embodiment, the blocking piece 22 further comprises a third plate body 225 connected between the first plate body 223 and the second plate body 224, and the accommodating cavity 221 is located between the first plate body 223, the second plate body 224 and the third plate body 225. The third plate body 225 can effectively limit the accommodating cavity 221, and the third plate body 225 can make the first plate body 223 and the second plate body 224 more stable.

[0032] As Figures 2 to 4 shown in the embodiment, the blocking piece 22 further comprises a fourth plate body 226 connected with the first plate body 223 and extending towards the inside of the material discharge channel 21. The fourth plate body 226 can guide the air discharged by the first air outlet hole 222 and prevent it from flowing randomly.

[0033] In addition, the fourth plate body 226 can also increase the stability of the blocking piece 22, and its extension towards the inside of the material discharge channel 21 can further guide the air flow, improve the sorting effect, and effectively improve the sorting speed and stability.

[0034] As Figures 2 to 4 shown in the embodiment, the fourth plate body 226 is provided with a plurality of second air outlet holes 2261. Part of the air discharged by the first air outlet hole 222 can be discharged through the second air outlet hole 2261 and blown onto the material entering the material discharge channel 21, thereby improving the flow speed of the material.

[0035] Specifically, the second air outlet hole 2261 can increase the range of air flow and improve the flexibility of sorting, which is suitable for sorting processes that require different air forces in different areas. For example, when processing mixed materials, the air force in different areas can be adjusted according to the characteristics of the materials to achieve the best sorting effect. When processing mixed materials, this design can adjust the air force according to the characteristics of the materials, effectively improve the sorting efficiency and quality, and reduce the waste of resources caused by inaccurate sorting.

[0036] As Figures 2 to 4 shown in the embodiment, the plurality of second air outlet holes 2261 include a first hole group and a second hole group, the first hole group and the second hole group are sequentially arranged along the height direction of the fourth plate body 226, and the diameter of the second air outlet hole 2261 in the first hole group is smaller than the diameter of the second air outlet hole 2261 in the second hole group. The above arrangement can improve the blowing effect.

[0037] It should be noted that the above design can realize the hierarchical action of wind force, and is suitable for occasions where multi-stage separation of materials is required. Specifically, light materials can be removed by the first group of holes through the first group of holes, and heavier materials can be blown by the second group of holes through the second group of holes. In this way, the accuracy and efficiency of separation are effectively improved.

[0038] As shown in Figures 2 to 4 In this embodiment, the fourth plate body 226 is provided with a sawtooth structure 2262 away from one end of the first plate body 223. The sawtooth structure 2262 can cut the wind, thereby improving the flow effect of the wind.

[0039] Specifically, the sawtooth structure 2262 can increase the disturbance effect of the wind force, and is suitable for occasions where the separation efficiency needs to be improved by wind disturbance. For example, when processing materials containing a large number of adherent particles, the sawtooth structure can effectively break the adhesion between the particles, thereby improving the efficiency and effect of separation. When processing materials with strong adhesion, such as ore containing dust or moisture, the sawtooth structure 2262 can effectively break the adhesion between the particles, thereby improving the separation efficiency and reducing the maintenance cost of the equipment. It is suitable for material processing in the mining, building material and other industries.

[0040] As shown in Figures 2 to 4 In this embodiment, the second plate body 224 is connected to the second end of the first plate body 223, and the first plate body 223 and the second plate body 224 are arranged vertically. The above arrangement can ensure the blocking effect of the material. Specifically, the third plate body 225 is arranged obliquely, and the third plate body 225 can support the second plate body 224, thereby improving the structural strength of the blocking piece 22.

[0041] Specifically, the height of the second plate body 224 is 1 to 3 times the upper limit of the particle size of the separated material.

[0042] As shown in Figure 2 In this embodiment, the fourth plate body 226 is connected to the second end of the first plate body 223, and the first plate body 223 and the fourth plate body 226 are arranged vertically. The above arrangement can avoid occupying a large space by the fourth plate body 226.

[0043] As shown in ​ In this embodiment, the discharge channel 21 has a first side wall 211 and a second side wall 212, and the fourth plate body 226 and the second side wall 212 have a ventilation gap. The above ventilation gap can guide the wind.

[0044] Specifically, the first side wall 211 is located between the second side wall 212 and the feeding end 11, the distance between the first side wall 211 and the second side wall 212 is distance a, and the distance between the fourth plate body 226 and the second side wall 212 is distance b, wherein the distance a and the distance b satisfy: 10 >= a / b >= 1. The distance between the fourth plate body 226 and the second side wall 212 is small, so that the space of the discharging channel 21 can be avoided, that is, the ratio can ensure the space of the discharging channel 21 and the space for the wind to flow.

[0045] In the embodiment, a / b = 3, and of course other values are also possible.

[0046] Specifically, the height of the fourth plate body 226 is 0.5 times to 2 times of the distance a.

[0047] The sorting device of the embodiment can effectively make the wind provided by the air supply structure act on the material in the discharging channel 21 by arranging the blocking piece 22 downstream of the inlet of the discharging channel 21, arranging the containing cavity 221 inside the blocking piece 22, and arranging the first air outlet hole 222 at the bottom of the blocking piece 22, so as to accelerate the flow speed of the material. At the same time, the structure design of the blocking piece 22 can effectively prevent the material from crossing the discharging channel 21 during the sorting process, thereby improving the sorting efficiency and the sorting accuracy.

[0048] In addition, the second air outlet hole 2261 and the sawtooth structure 2262 on the fourth plate body 226 further enhance the sorting effect, so that the device can significantly improve the sorting efficiency and reduce the energy consumption in actual application, and has significant economic benefits and environmental benefits.

[0049] In actual application, the sorting device can be widely applied to the sorting of various particulate materials, such as ores, coal, grains, plastic particles, electronic waste, etc., and can not only improve the accuracy and efficiency of sorting, but also reduce energy consumption and environmental pollution, and has wide application prospect and market potential.
