Obviously, the described embodiments are some, but not all, of the embodiments of the present application. Usually, the components of the embodiments of the present application described and illustrated herein can be arranged and designed in various different configurations.

[0028] As Figures 1 to 6 Shown, a pneumatic separation equipment 100 of the present utility model includes a frame 1, a feeding and discharging device 2, a folding plate box body 3, a fan 4, and a cyclone aggregate hopper 5.

[0029] The frame 1 may include a plurality of support feet 11 and a frame platform 12. The folding plate box body 3, the fan 4, and the cyclone aggregate hopper 5 may be arranged side by side on the frame platform 12 of the frame 1 and can be integrated into an integral structure.

[0030] The folded plate box body 3 is vertically installed on the left side of the frame platform 12 of the frame 1. The upper side input port 31 of the folded plate box body 3 is connected to the discharge port 21 of the feeding and discharging device 2. The upper output port 32 at the top of the folded plate box body 3 is communicated with the inlet of the cyclone aggregate hopper 5 through the upper pipeline 6. The bottom of the folded plate box body 3 is provided with a lower output port 33. The lower part of the folded plate box body 3 is communicated with the air outlet 41 of the fan 4 through the lower pipeline 7. The air inlet 42 of the fan 4 is communicated with the middle air return port 51 on the top surface of the cyclone aggregate hopper 5 through the air return pipeline 8.

[0031] Thus, the feeding and discharging device 2 feeds materials such as construction waste into the folded plate box body 3. The materials in the folded plate box body 3 will be leveled. Then, the lower part of the folded plate box body 3 is connected to the air inlet of the air outlet 41 of the fan 4, and the upper output port 32 at the top is used for air extraction. The light materials will be sucked into the cyclone aggregate hopper 5 from the upper output port 32 along with the flow of the air, while the heavy materials will fall from the lower output port 33 at the bottom due to the action of gravity, thereby realizing the automatic separation of the light materials and the heavy materials. The effect of removing substances such as plastic bags and wrapping papers in the construction aggregate can reach more than 95%. The layout structure in which the folded plate box body 3, the fan 4 and the cyclone aggregate hopper 5 can be arranged side by side on the frame 1 can reduce the overall floor area of the equipment, save space and save site costs.

[0032] Refer to Figure 2 , a light material discharging device 9 is connected to the conical bottom of the cyclone aggregate hopper 5 to discharge the light materials collected by the cyclone aggregate hopper 5.

By setting the feeding grooves 232, the materials at the feeding port 25 are quantitatively separated to avoid blockage caused by excessive materials at the feeding port 25. At the same time, the quantitatively separated materials can smoothly enter the folded plate box body 3 after being output from the discharge port 21.

[0036] The feeding motor 24 can be installed outside the feeding box body 22, and the output shaft of the feeding motor 24 is connected to the feeding shaft 23 for driving the feeding shaft 23 to rotate.

[0038] The lower part of the folding plate box body 3 is provided with a lower box body 37; the upper part of the lower box body 37 includes a left connection port 371 and a right connection port 372. The left connection port 371 is butted against the bottom of the separation channel 36, and the right connection port 372 is connected to the fan 4 through a lower pipeline 7; the lower part of the lower box body 37 is gradually tapered to form a lower output port 33 opposite to the lower part of the separation channel 36; the heavy substances fall in the separation channel 36 and are output along the lower part of the lower box body 37, and the air outlet 41 of the fan 4 is connected to the right connection port 372, so that the air will enter from the left connection port 371, be affected by the gradually tapered side wall 373 on the right side of the lower part of the lower box body 37 and blow to the left connection port 371 and then enter the separation channel 36; moreover, the top of the separation channel 36 is simultaneously communicated with the air inlet 42 of the fan 4, having an air extraction effect and also guiding the air from the air outlet 41 to the separation channel 36.

[0039] Refer to Figure 2 and Figure 4 As shown in FIGS. and, specifically, the lower pipeline 7 can be a bent pipe, and a civil air defense flap valve 71 is arranged near the air outlet 41 of the fan 4 to isolate or conduct the ventilation of the fan 4, and the fan 4 can be a high-pressure fan 4.

[0040] Refer to Figure 1 and Figure 2 As shown in FIGS. and, the upper pipeline 6 includes a connected elbow section 61 and a straight section 62. The other end of the elbow section 61 is connected to the upper output port 32, and the other end of the straight section 62 is connected to the inlet on the top side of the cyclone aggregate hopper 5. In this way, the cooperation between the folding plate box body 3 and the cyclone aggregate hopper 5 is more compact.

[0042] In summary, by integrating the folding plate box body 3, the fan 4, and the cyclone aggregate hopper 5 onto a single frame 1 and connecting them integrally through the upper pipeline 6, the lower pipeline 7, and the return air pipeline 8, the overall volume and floor area of the equipment can be effectively reduced, saving costs.

[0043] Moreover, the input port 31 of the folding plate box body 3 can be connected to a feeding and discharging device 2 including a feeding shaft 23 and a feeding chute 232, which can make the feeding smoother and less prone to blockage, improving work efficiency.
