[0002] The air separator is based on the principle of aerodynamics and uses controllable airflow as the sorting medium. It consists of coarse crushing device, fine crushing device and wind conveying device. Under the action of the centrifugal fan, a negative pressure environment is formed inside the system. Using the rising airflow formed by the negative pressure, light materials will move upward under the action of the rising airflow, while heavy materials will fall because the rising airflow cannot support them.

[0003] In the prior art, when performing air separation, the air separator first uses high-speed impact to achieve the purpose of crushing and breaking up the large materials formed by a large number of small materials, so that under the action of the rising air flow, the small materials are separated from the large materials, while the large materials continue to move along the conveyor belt.

[0004] However, when this type of air separator is performing air separation, small materials such as paper pieces, plastic bags and films adhere to the conveyor belt due to the moisture on them. The moisture causes the gravity to increase, and they cannot move upward for separation under the action of the rising airflow. Utility Model Content

[0029] Example 1

[0030] This embodiment provides a kind of breaking type negative pressure horizontal air separator, such as Figure 1 and5 As shown, it includes an assembly line frame 1, a separation bin 2 is fixedly installed on the top of the assembly line frame 1, a main negative pressure pipe 3 is fixedly installed on the top of the separation bin 2, a plurality of auxiliary negative pressure pipes are opened on the side of the main negative pressure pipe 3, the auxiliary negative pressure pipes are connected to the interior of the separation bin 2, the inlet of the auxiliary negative pressure pipe is vertically downward, and the end of the main negative pressure pipe 3 is connected to the centrifugal fan 5.

[0031] Under the action of the centrifugal fan 5, a negative pressure environment is formed inside the separation bin 2, and an upward airflow is generated. The material inside the separation bin 2 is air-selected by the airflow. When the lifting force exerted by the upward airflow on the material is greater than the gravity of the material, the material will move upward and be discharged from the separation bin 2 through the main negative pressure pipe 3 and the auxiliary negative pressure pipe; when the lifting force exerted by the upward airflow on the material is less than the gravity of the material, the material cannot rise.

[0032] The air separator is equipped with a dust removal system, which can effectively handle the dust generated during the operation of the equipment to ensure a clean and safe working environment. With the assistance of the dust removal system, the air separator is closed and dust-free during operation.

[0033] like Figure 1 As shown, a scattering device 4 is fixedly installed on the top of the assembly line frame 1 and on the left side of the separation bin 2. The scattering device 4 scatters and crushes the small materials gathered together, and crushes and scatters the large materials formed by a large number of small materials, so that the small materials are separated from the large materials under the action of the rising airflow.

[0034] like Figure 2 and 3 As shown, an auxiliary separation component 6 is arranged on the top of the assembly line frame 1, and the auxiliary separation component 6 includes a material conveyor belt 61, a heat hole 62, a separation rotating rod 63 and a heating plate 64. The material conveyor belt 61 is rotatably connected to the assembly line frame 1 through a rotating shaft. The material conveyor belt 61 is parallel to the top surface of the assembly line frame 1, and materials are transported above the material conveyor belt 61.

[0035] The material is transported by the material conveyor belt 61. The material on the material conveyor belt 61 is transported from the scattering device 4 to the separation bin 2. The material is first crushed and scattered by the scattering device 4, and then enters the separation bin 2 for air separation. Small materials move upward under the action of negative pressure, and large materials continue to move to the right under the transportation of the material conveyor belt 61, and are then thrown out by the material conveyor belt 61. Large materials are thrown out in the direction due to inertia, and the throwing distance of large materials varies according to the density and particle size of the materials, thereby realizing the separation of large materials.

[0036] like Figure 3As shown, a heat hole 62 is provided on the material conveyor belt 61, and a heating plate 64 is arranged at the annular center position of the material conveyor belt 61. Both ends of the heating plate 64 are fixedly connected to the separation bin 2, and the heat emitted by the heating plate 64 flows upward from the heat hole 62. The heat emitted by the heating plate 64 dries the wet material on the material conveyor belt 61, thereby preventing small materials from adhering to the material conveyor belt 61 due to moisture, and moisture also increases the gravity of small materials, affecting the air separation accuracy of the air separator.

[0037] like Figure 2 and 4 As shown, the separation rotating rod 63 is arranged above the material conveyor belt 61, and both ends of the separation rotating rod 63 are rotatably connected to the separation bin 2, and a separation lifting rod 66 is fixedly installed on the rod body of the separation rotating rod 63. A plurality of separation lifting rods 66 are arranged in groups, and a plurality of separation lifting rods 66 are arranged in each group. The plurality of separation lifting rods 66 in a group are distributed in a circular manner at equal angles on the rod body of the separation rotating rod 63, and the positions of two adjacent groups of separation lifting rods 66 are staggered, and the end of the separation lifting rod 66 away from the separation rotating rod 63 is in contact with the material conveyor belt 61.

[0038] A motor is fixedly installed at the end of the separation rotating rod 63, which drives the separation rotating rod 63 to rotate counterclockwise, so that the separation rotating rod 63 rotates counterclockwise to pick up the material adhering to the material conveyor belt 61, and cooperates with the heating plate 64 to heat the material to evaporate the moisture on the material, thereby preventing the moisture from affecting the air separation of the air separator.

[0039] The separation rod 66 adopts a cylindrical structure. The separation rod 66 contacts the material transported by the material conveyor belt 61. The separation rotating rod 63 rotates counterclockwise. The linear speed of the separation rotating rod 63 is faster than the linear speed of the material conveyor belt 61. If the linear speed of the separation rotating rod 63 is the same as the linear speed of the material conveyor belt 61, the separation rotating rod 63 cannot play a lifting effect. At the same time, the separation rotating rod 63 is used in conjunction with the scattering device 4 to dry the material after lifting it to prevent the material from adhering to the material conveyor belt 61 after drying. At the same time, the negative pressure of the main negative pressure pipe 3 and the centrifugal fan 5 absorbs the water evaporated from the heating plate 64 and discharges it from the separation bin 2.

[0040] A preheating port 65 is provided on the left side of the separation bin 2. Hot air in the separation bin 2 flows from the preheating port 65 into the scattering device 4. When the scattering device 4 scatters and separates the materials, the materials are preheated.

[0041] In this embodiment, the material on the material conveyor belt 61 is heated by the heating plate 64 to dry the material to prevent the material from becoming heavier due to moisture and being unable to be floated by the rising air flow. The separation rotating rod 63 and the separation lifting rod 66 rotate to lift the material from the material conveyor belt 61, and cooperate with the heating plate 64 for heating to prevent the dried material from adhering to the material conveyor belt 61 and being unable to be separated.

[0042] The above-mentioned specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
