[0026] As Figure 1 and Figure 2 shown, in the present embodiment, the cross-flow sorting device includes a sorting bed 10, a wind supply structure 20, and a first air distribution plate 30. The sorting bed 10 has a feed end 11 and a discharge end 12. The wind supply structure 20 is arranged below the sorting bed 10 and communicates with the sorting bed 10. The first air distribution plate 30 is arranged on the sorting bed 10, and a plurality of strip-shaped holes 31 are arranged on the first air distribution plate 30, and the length direction of each strip-shaped hole 31 is the same as the direction from the feed end 11 to the discharge end 12.

[0027] By applying the technical solution of the present embodiment, the sorting bed 10 has a feed end 11 and a discharge end 12. The wind supply structure 20 is arranged below the sorting bed 10 and communicates with the sorting bed 10. The first air distribution plate 30 is arranged on the sorting bed 10, and a plurality of strip-shaped holes 31 are arranged on the first air distribution plate 30, and the length direction of each strip-shaped hole 31 is the same as the direction from the feed end 11 to the discharge end 12. Through the above arrangement, the wind supply structure 20 blows air into the sorting bed 10 and blows out through the strip-shaped holes 31 on the first air distribution plate 30, thereby effectively realizing cross-flow sorting. Moreover, the arrangement of the strip-shaped holes 31 can increase the flow area and avoid material blockage, thereby improving the sorting effect. Therefore, the technical solution of the present embodiment effectively solves the problem that the circular air distribution holes in the related art are prone to material blockage, which affects the sorting effect.

[0028] Specifically, through the above design, the cross-flow sorting device can uniformly distribute air to every corner of the sorting bed 10, effectively avoiding the common problem of uneven air distribution in traditional sorting devices, thereby improving the efficiency and accuracy of sorting. The cross-flow sorting device of the present embodiment is particularly suitable for processing materials with a wide particle size distribution, such as ores, coal, plastic particles, etc., and can realize large-scale material sorting in industrial production.

[0029] AsFigure 1 and Figure 2 As shown in

[0030] Specifically, the staggered arrangement of the hole groups can further optimize the wind distribution, making the wind more uniform on the sorting bed 10, and avoiding the problem of uneven sorting caused by excessive or insufficient local wind.

[0031] As shown in Figure 1 and Figure 2 In this embodiment, the length of the strip-shaped hole 31 is 2-10 times the width of the strip-shaped hole 31, and the width of the strip-shaped hole 31 is greater than the lower limit of the particle size of the material to be sorted. The above arrangement can ensure the area of the air outlet and avoid the occurrence of material jamming.

[0032] It should be noted that the length of the strip-shaped hole can be between 6mm and 17mm. Specifically, in this embodiment, the size of the strip-shaped hole 31 is 14mm, and of course, it can also be 7mm, 8mm, 9mm, 10mm, 11mm or other sizes.

[0033] It should be noted that the strip-shaped hole 31 of this size can provide sufficient wind force while avoiding excessive material dispersion caused by excessive wind force, maintaining the stable flow of the material on the sorting bed.

[0034] As shown in Figure 1 and Figure 3 In this embodiment, the sorting bed 10 is also provided with a first air chamber 13, which is located below the first air distribution plate 30. The air supply structure 20 is in communication with the first air chamber 13, and a plurality of first partition plates 131 are arranged in the first air chamber 13. The plurality of first partition plates 131 are arranged adjacent to the first air distribution plate 30, and the plurality of first partition plates 131 are arranged at intervals from the feed end 11 to the discharge end 12. The above arrangement can split the air, and then make the air blow to the first air distribution plate 30 more uniformly.

[0035] Specifically, by arranging the first air chamber 13 and the first partition plate 131, the distribution of the wind can be effectively controlled, so that the wind acts more uniformly on the sorting bed 10, improving the consistency and stability of the sorting.

[0036] In this embodiment, the angle between the first partition plate 131 and the horizontal plane is between 25° and 70°.

[0037] As shown in Figure 1 and Figure 3 In the embodiment, the air guide channel 132 is formed between two adjacent first partition plates 131 and is arranged obliquely towards the discharge end 12. The above arrangement can realize air blowing towards the discharge end 12, and in combination with the strip-shaped hole 31, can realize air blowing in the pulsation direction, thereby being more conducive to realizing the flow-through sorting process of the material in the pulsation process.

[0038] Specifically, the obliquely arranged air guide channel 132 can guide the air force along the direction of the material flow, which is conducive to the stable flow of the material and avoids the accumulation or uneven distribution of the material on the sorting bed 10, thereby improving the sorting efficiency.

[0039] As shown in Figure 1 and Figure 3 In the embodiment, a plurality of second partition plates 133 are further arranged in the first air chamber 13, and the plurality of first partition plates 131 and the plurality of second partition plates 133 are arranged one by one, the first end of the second partition plate 133 is connected with the corresponding first partition plate 131, and the second end of the second partition plate 133 is connected with the inlet of the first air chamber 13. The arrangement of the second partition plate 133 can realize the division of the air at the inlet end of the first air chamber 13, thereby making the division effect better.

[0040] That is, by arranging the second partition plate 133, the control of the air force can be further refined, the distribution of the air force is more uniform, and the sorting precision is improved.

[0041] As shown in Figure 1 and Figure 3 In the embodiment, the width of the first air chamber 13 gradually decreases from the first air distribution plate 30 to the first air chamber 13, and the corresponding first partition plate 131 and the second partition plate 133 are arranged at an obtuse angle or in parallel. The above arrangement can ensure the uniformity of the air and can ensure that the air guide channel 132 blows towards the discharge end.

[0042] In the embodiment, the gradual decrease of the width of the first air chamber 13 and the obtuse angle or parallel arrangement between the first partition plate 131 and the second partition plate 133 can make the air force form a gradual distribution on the sorting bed 10, which has a remarkable sorting effect on the treatment of mixed materials. When treating such materials, layering and separation are particularly important, and this design can effectively improve the sorting precision and efficiency.

[0043] Currently, most existing air classification equipment uses a porous air distribution plate with uniform apertures (1.5-17mm). However, in actual classification processes, different stages require different air velocities and uniform air distribution mechanisms, and a porous air distribution plate with uniform apertures cannot meet the requirements for efficient air distribution. At the product inlet, the low air velocity cannot fully loosen and stratify the material, and the sudden increase in material can lead to bed compaction. At the discharge stage, the high air velocity causes back-mixing of the stratified material, worsening the classification effect. In the through-flow classification section, the air holes perpendicular to the bed surface cannot guarantee the highest efficiency of through-flow.

[0044] To solve the above-mentioned technical problems, such as Figure 1 As shown, in this embodiment, the through-flow sorting device further includes a second air distribution plate 40 and a third air distribution plate 50. The sorting bed 10 is also equipped with a second air chamber 14 and a third air chamber 15. The air supply structure 20 is connected to both the second air chamber 14 and the third air chamber 15. From the feed end 11 to the discharge end 12, the third air distribution plate 50, the second air distribution plate 40, and the first air distribution plate 30 are arranged sequentially. Similarly, the third air chamber 15, the second air chamber 14, and the first air chamber 13 are arranged sequentially. The third air chamber 15 corresponds to the third air distribution plate 50, and the second air chamber 14 corresponds to the second air distribution plate 40. This arrangement allows for targeted air supply for different sorting stages on the sorting bed 10, thereby improving the sorting effect and efficiency.

[0045] The second air distribution plate 40 and the third air distribution plate 50 can have round holes or elongated holes, but the hole diameter on the second air distribution plate 40 and the third air distribution plate 50 is smaller than the hole diameter on the first air distribution plate 30.

[0046] like Figure 1 and Figure 4 As shown, in this embodiment, the second air distribution plate 40 includes a packing structure 41 and a plate body 42. The plate body 42 is located above the packing structure 41, and a plurality of through holes 421 are arranged in an array on the plate body 42. The above arrangement can improve the uniformity of the air outlet.

[0047] Specifically, the second air distribution plate 40 can achieve fine adjustment of the wind force through the packing structure 41 and the multiple through holes 421 provided on the plate body 42. The packing structure 41 can adjust the magnitude and direction of the wind force, thereby improving the flexibility and adaptability of sorting.

[0048] In this embodiment, the packing structure consists of a support and packing. The packing is a low-density, lightweight material with a particle size larger than the aperture of the through hole 421. The support is used to support the packing and prevent the packing from leaking into the air supply structure 20.

[0049] like Figure 1As shown, in this embodiment, the through-flow sorting device further includes a first discharge structure 60 and a second discharge structure 70. The first discharge structure 60 includes a first discharge port 61 and a first discharge wheel 62 located within the first discharge port 61. The second discharge structure 70 includes a second discharge port 71 and a second discharge wheel 72 located within the second discharge port 71. The first discharge port 61 and the second discharge port 71 are spaced apart. The first discharge port 61 is located between the second air distribution plate 40 and the first air distribution plate 30, and the second discharge port 71 is located between the first air distribution plate 30 and the discharge end 12. The aforementioned first discharge structure 60 and second discharge structure 70 can achieve the sorting of materials with different particle sizes, thereby improving the sorting quality.

[0050] like Figure 1 As shown, in this embodiment, the air supply structure 20 includes a main air supply pipe and multiple branch air supply pipes. The main air supply pipe is connected to multiple branch air supply pipes, which are respectively connected to the first air chamber 13, the second air chamber 14, and the third air chamber 15. The multiple branch air supply pipes are equipped with manual air valves and pulsating air valves. The manual air valves are used to adjust the magnitude of the pulsating air velocity in the branch air supply pipes, and the pulsating air valves are used to adjust the pulsating period and the magnitude of the pulsating air velocity.

[0051] The flow separation device also includes a flow discharge device located at the far end of the air supply structure 20, which is used to discharge the material that flows through the strip hole 31 on the first air distribution plate 30.
