[0038] The embodiment provides a separation device for separating light substances 61 in solid waste. As shown in Figures 1-5As shown, the separation device includes a separation chamber 1, a blowing pipeline 2 and a suction pipeline 3. The separation chamber 1 is provided with a feeding port 11 and is used to accommodate solid waste. The blowing pipeline 2 is connected with the separation chamber 1. The side wall of the blowing pipeline 2 is circumferentially provided with at least two first air outlets 21. The blowing pipeline 2 can transport a positive pressure airflow. The positive pressure airflow flows out of the first air outlets 21 and flows along the inner wall of the separation chamber 1, so as to separate the light substance 61 from the solid waste. The suction pipeline 3 is connected with the separation chamber 1 and is provided with a suction port 31. The suction port 31 is provided with the first air outlets 21 on both sides. The suction pipeline 3 can transport a negative pressure airflow. The negative pressure airflow is used to adsorb the separated light substance 61. In this way, the separation of the light substance 61 in the solid waste is realized. The device effectively improves the separation efficiency. The light substance 61 pressed under the heavy substance 62 can also be separated. The light substance 61 is accurately separated, and the treatment effect of the solid waste is guaranteed.

[0039] Specifically, the solid waste includes light substance 61 and heavy substance 62. The solid waste treated by the separation device covers various types of household garbage, construction waste, etc. The separation device is used to separate the light substance 61 from the heavy substance 62. The light substance 61 is a film type, and the heavy substance 62 is a material with large density and hard texture, such as metal, hard plastic, large particle ore, etc. The specific composition of the heavy substance 62 and the light substance 61 is not limited, and they can be flexibly adjusted according to the actual situation. These heavy substances 62 often need greater force to be treated in the separation process. The light substance 61 is more easily separated from the heavy substance 62 under the action of the positive pressure airflow due to its light weight and relatively loose structure.

[0040] Specifically, as shown in Figure 2 and Figure 4 , the side wall of the blowing pipeline 2 is circumferentially provided with two first air outlets 21. The opening of the first air outlet 21 faces the side wall of the separation chamber 1. The suction port 31 is located between the two first air outlets 21 and faces the solid waste. The flow direction of the positive pressure airflow is the X direction as shown in Figure 4 , and the flow direction of the negative pressure airflow is the Y direction as shown in Figure 4 . After the positive pressure airflow flows out of the first air outlets 21 on both sides, it flows down along the side wall of the separation chamber 1, thereby forming a positive pressure airflow from bottom to top. The solid waste is blown away from bottom to top, so that the light substance 61 and the heavy substance 62 are completely separated. This design effectively improves the separation efficiency and avoids the situation that the light substance 61 is difficult to separate because it is pressed under the heavy substance 62. After the light substance 61 is blown away, the negative pressure airflow of the suction pipeline 3 can accurately adsorb the light substance 61 under the cooperation of the first air outlets 21 on both sides. Because the light substance 61 is dispersed, the negative pressure airflow acts in time to ensure that the light substance 61 does not stay in the separation chamber 1 for too long time, realizes accurate collection, and guarantees the solid waste treatment effect.

[0041] Further, as shown in Figure 2 , the first air outlet 21 is rectangular. The rectangular design makes the positive pressure airflow flow uniformly along the side wall of the separation chamber 1, increases the contact area with solid waste, and improves the blowing effect. Its size is determined according to actual needs and the space of the separation chamber 1, which can effectively improve the separation efficiency. In other embodiments, the first air outlet 21 can also be runway-shaped, circular, streamlined or polygonal, which is not specifically limited here.

[0042] In other embodiments, in order to further improve the separation efficiency, the number of first air outlets 21 of the blowing pipe 2 can be adjusted according to actual needs, and three or four equal numbers of first air outlets 21 can be provided. When the number of first air outlets 21 increases, the distribution of positive pressure airflow is more uniform, and the blowing effect on solid waste is more significant. This not only enables the light substance 61 to be more fully separated from the heavy substance 62, but also speeds up the separation.

[0043] Specifically, the separation device further comprises a blower and a vacuum pump, the blower is connected with the blowing pipe 2 to generate a positive pressure airflow, and the vacuum pump is connected with the suction pipe 3 to generate a negative pressure airflow. The specific structure and working principle of the blower and the vacuum pump belong to the prior art, which will not be described here.

[0044] As shown in Figure 2 and Figure 4 , part of the suction pipe 33 penetrates the blowing pipe 22, and the positive pressure airflow is divided along the outer wall of the suction pipe 33 and flows out from the first air outlet 21. In this separation device, the positive pressure airflow is divided along the outer wall of the suction pipe 3 when flowing from the blowing pipe 2 to the suction pipe 3, forming a surrounding airflow field. The airflow is accelerated to flow out due to the pressure difference at the first air outlet 21, which produces a pushing effect on the light substance 61, overcomes the gravity and resistance to make it separate from the solid waste. At the same time, the suction pipe 3 penetrating the blowing pipe 2 forms a stable negative pressure adsorption area near the first air outlet 21, and the light substance 61 is quickly adsorbed after being separated, realizing high-efficiency separation and precise collection.

[0045] Further, as shown in Figure 2 , the suction pipe 33 comprises two guide portions 32 connected at an angle, and the two guide portions 32 are located in the blowing pipe 22, and the distance between the two guide portions 32 gradually increases along the flow direction of the positive pressure airflow. The flow direction of the positive pressure airflow is as shown in Figure 2As shown in the X direction, after the positive pressure airflow enters the blowing duct 2, due to the angle between the guide sections 32, it flows along the surfaces of the two guide sections 32, forming split airflows in different directions. As the distance between the guide sections 32 and the direction of the positive pressure airflow gradually increases, the mutual interference and mixing between the split airflows intensifies, forming turbulence, breaking the original laminar flow state, and making the energy more evenly distributed. During this process, the actual path length of the positive pressure airflow in the blowing duct 2 increases, and the residence time in the duct is prolonged. This allows the positive pressure airflow to fully acquire energy, thereby driving the light material 61 to separate from the solid waste with a more stable and powerful force.

[0046] like Figure 2 As shown, one end of the blowing duct 2 is provided with an air inlet 22, and the other end of the blowing duct 2 is sealed. The air inlet 22 introduces positive pressure airflow. Due to the sealing, a stable positive pressure environment is formed. The positive pressure airflow accumulates in the blowing duct 2, and the pressure increases to form a pressure difference, which promotes the increase of the positive pressure airflow intensity. At the same time, the constraint of the inner wall of the blowing duct 2 and the action of the guide part 32 make the airflow distribution uniform, which is conducive to the separation of light materials 61 from solid waste.

[0047] like Figures 1-3 As shown, the blowing duct 2 includes a variable diameter section 23, located between the air inlet 22 and the first air outlet 21. The diameter of the variable diameter section 23 gradually decreases along the flow direction of the positive pressure airflow. As the cross-sectional area of ​​the blowing duct 2 gradually decreases, the velocity of the positive pressure airflow increases, and the pressure rises accordingly. Simultaneously, the constraint effect of the inner wall of the blowing duct 2 on the positive pressure airflow makes its distribution more uniform and stable. These changes enable the positive pressure airflow to more efficiently propel the light material 61 from the solid waste, achieving a good separation effect.

[0048] Specifically, such as Figures 1-3 As shown, the variable diameter section 23 is located outside the separation chamber 1. This arrangement effectively avoids the variable diameter section 23 affecting the opening size of the first air outlet 21 inside the separation chamber 1. Since the diameter of the variable diameter section 23 gradually decreases along the direction of positive pressure airflow, the airflow velocity increases and the pressure rises on the side closest to the separation chamber 1. If the variable diameter section 23 were inside the separation chamber 1, its diameter change process would interfere with the opening size of the first air outlet 21, leading to unstable airflow and poor separation of light materials 61. By placing the variable diameter section 23 outside the separation chamber 1, not only is sufficient acceleration of the positive pressure airflow ensured before entering the separation chamber 1, but the airflow also remains stable upon entering the separation chamber 1, ensuring that the opening size of the first air outlet 21 is not affected. This allows the light materials 61 to be efficiently separated from the solid waste under the action of a stable airflow.

[0049] like Figure 4 and Figure 5As shown, the separation device further comprises two sets of symmetrically arranged air volume adjusting assemblies 4 connected with the inner wall of the separation chamber 1, for adjusting the air volume of the positive pressure airflow in the separation chamber 1. Since the air volume adjusting assemblies 4 are symmetrically arranged, they can synchronously adjust the positive pressure airflow, so that the positive pressure airflow is evenly distributed in the separation chamber 1. Specifically, when the air volume adjusting assemblies 4 move towards the inner wall of the separation chamber 1, the cross-sectional area of the airflow passage decreases, the airflow speed increases, and the air volume increases; on the contrary, when the air volume adjusting assemblies 4 move away from the inner wall of the separation chamber 1, the cross-sectional area of the passage increases, the airflow speed decreases, and the air volume decreases. This adjustment process not only accurately controls the air volume to meet the needs of separating the light substance 61 under different working conditions, but also enables the light substance 61 to be more efficiently separated from the solid waste under the action of uniform airflow.

[0050] As shown in Figure 5 The air volume adjusting assembly 4 comprises an adjusting plate 41, one end of the adjusting plate 41 abuts against the outer wall of the blowing pipeline 2, the other end of the adjusting plate 41 forms a second air outlet 14 with the side wall of the separation chamber 1, and the adjusting plate 41 is movably connected with the separation chamber 1 to adjust the size of the second air outlet 14. When the positive pressure airflow is constant, the speed and flow of the positive pressure airflow are adjusted by changing the cross-sectional area of the second air outlet 14 to achieve air volume adjustment. At the same time, the specific angle and shape formed by the adjusting plate 41 and the side wall of the separation chamber 1 guide the positive pressure airflow to flow at a suitable angle and direction in the separation chamber 1, optimizing the airflow distribution. In addition, the adjusting plate 41 can also separate the positive pressure airflow and the negative pressure airflow, so that they form different pressure areas in the separation chamber 1. The positive pressure airflow changes its speed and flow through the second air outlet 14, and its action in the separation chamber 1 changes due to the change in the size of the air outlet. The interaction between the negative pressure airflow and the positive pressure airflow also changes with the change of the positive pressure airflow, together creating an environment conducive to the separation of the light substance 61.

[0051] As shown in Figure 5 The air volume adjusting assembly 4 further comprises a fastener 42, the inner wall of the separation chamber 1 is provided with a positioning hole 12 and a circular arc hole 13 arranged around the positioning hole 12, and the two sides of the adjusting plate 41 are provided with rotating portions 411, the rotating portions 411 are inserted into the positioning hole 12 to enable the adjusting plate 41 to rotate around the positioning hole 12, and the fastener 42 is inserted into the circular arc hole 13 to fix the adjusting plate 41. The adjusting plate 41 can rotate around the positioning hole 12, which enables the adjusting plate 41 to change the size of the second air outlet 14 according to actual needs, thereby achieving flexible adjustment of the air volume. This flexibility provides adaptability for different separation conditions and can meet the needs of separating various light substances 61. The fastener 42 is inserted into the circular arc hole 13 to fix the adjusting plate 41 at a specific position. This ensures that the adjusting plate 41 will not move randomly during the adjustment process, ensuring the stability and reliability of the adjustment. During the separation process, the stable adjusting plate 41 helps to maintain the stability of the positive pressure airflow, improving the separation effect.

[0052] Specifically, in combination with Figure 5 , when adjusting the cross-sectional area of the second air outlet 14, the fastener 42 is removed to allow the adjustment plate 41 to move. Then, the adjustment plate 41 is rotated around the positioning hole 12, and the arc hole 13 limits the rotation of the adjustment plate 41 to accurately adjust the cross-sectional area. Rotating downward can increase the cross-sectional area, slow down the airflow speed, and reduce the air volume; rotating upward can reduce the cross-sectional area, speed up the airflow, and increase the air volume. After adjustment, the fastener 42 is inserted into the arc hole 13 again to fix the adjustment plate 41, ensuring its stability and maintaining the stability of the positive pressure airflow in the separation chamber 1, providing suitable air volume for efficient separation of light substances 61 to meet the needs of different working conditions.

[0053] Specifically, the fastener 42 can be selected from screws, bolts, etc., which are not limited here, as long as the fastening of the adjustment plate 41 is firm.

[0054] As shown in Figure 1 , the separation device further includes a conveying mechanism 5, and the separation chamber 1 is located above the conveying mechanism 5. The conveying mechanism 5 can move the solid waste along the Figure 1 Z direction (this is the conveying direction), and the solid waste enters the separation chamber 1 through the feed port 11. The conveying mechanism 5 can carry the remaining solid waste out of the separation chamber 1 after the light substances 61 are separated. The conveying mechanism 5 realizes efficient separation by continuously conveying solid waste, allowing the light substances 61 to be separated from the solid waste under the action of positive pressure airflow and then carrying the remaining solid waste, i.e., heavy substances 62, out of the separation chamber 1, ensuring that the separation process proceeds in an orderly manner. At the same time, precise control of the moving direction and speed of the solid waste allows the light substances 61 to be fully separated, improving separation quality and reducing light substance 61 residue. The operation also allows the separation device to continuously work and process new solid waste, improving overall production efficiency.

[0055] Specifically, the conveying mechanism 5 uses a belt conveyor, which is simple in structure, highly adaptable, flexible in adjustment, and widely applicable. Since the belt conveying technology is quite mature, the specific components are not described here.

[0056] Further, the opening extension direction of the first air outlet 21 is the same as the conveying direction of the conveying mechanism 5, and the positive pressure airflow is perpendicular to the conveying direction, blowing the solid waste from both sides downward. This process realizes efficient separation of the light substances 61 and the heavy substances 62, allowing the light substances 61 to separate from the solid waste under the action of the airflow and float upward. Since the airflow is uniformly blown upward from both sides, the solid waste is uniformly stressed to avoid light substance 61 residue, and the separated light substances 61 are easily collected and subsequently processed under the action of the airflow.

[0057] Obviously, the above embodiments of the present application are merely examples for clearly illustrating the present application, and are not intended to limit the implementation modes of the present application. For those skilled in the art, various obvious changes, re-adjustments and replacements can be made without departing from the protection scope of the present application. Here, it is not necessary and also impossible to enumerate all the implementation modes. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application claim.
