[0001] This utility model relates to the field of waste sorting, specifically to a durable and easily adjustable horizontal air separator. Background Technology

[0002] Waste is typically processed by coarse crushing equipment into a mixture of small solids, lightweight materials, and dust, which is then transported to an air separation chamber to separate small pieces, thin films, and dust.

[0003] The horizontal air classifier is a commonly used sorting device. The size of the guiding screening chamber of this air classifier is adjusted by using an electric push rod to drive an arc-shaped plate to swing on the guide pipe. This design has the following two problems: First, there are particles of different sizes in the screening chamber. These particles diffuse and spread in the screening chamber, which will have a serious negative impact on the service life of the electric push rod. Second, the arc-shaped plate is located inside the machine body, making it difficult to accurately control its swing angle when adjusting it. Utility Model Content

[0004] To address one or more of the aforementioned problems, this utility model provides an easy-to-adjust and durable horizontal air separator.

[0005] According to one aspect of the present invention, an easy-to-adjust and durable horizontal air classifier includes a housing, a first conveying device, a second conveying device, an air blowing nozzle, and an exhaust pipe. The air inlet end of the exhaust pipe is provided with two arc-shaped baffles, which form a funnel-shaped screening space. A rotating shaft is fixedly connected to each of the two arc-shaped baffles. Both ends of the rotating shaft are equipped with seated bearings, which are embedded in the housing. Both ends of the two rotating shafts are fixedly connected with swing rods. The swing rods are located outside the housing and are arranged parallel to the arc-shaped baffles. The housing is provided with an adjustment component that swings the arc-shaped baffles on the rotating shafts via the swing rods.

[0006] In some embodiments, the adjustment component includes two control components and two first drive components, which are symmetrically arranged on both sides of the housing. The control components adjust the swing arm by means of the first drive components.

[0007] In some embodiments, the adjustment component includes a control component and a second drive component disposed in the middle of the housing, wherein the control component simultaneously adjusts the swing of the two swing levers through the second drive component.

[0008] In some embodiments, the control component includes a fixed plate fixedly connected to the housing, a screw slidably connected to the fixed plate, a first locking nut and a second locking nut threaded onto the screw, and the first locking nut and the second locking nut being located on opposite sides of the fixed plate.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to the directions in the accompanying drawings, while the terms "inner" and "outer" refer to the directions toward or away from the geometric center of a specific component, respectively.

[0019] Figures 1 to 6 The illustration schematically shows an adjustable and durable horizontal air separator according to the present invention. Example 1

[0020] Please see Figures 1 to 4As shown, this utility model provides an easy-to-adjust and durable horizontal air classifier, including a housing 1, a first conveying device 2, a second conveying device 3, a blowing nozzle 4, and an exhaust pipe 5. The air inlet end of the exhaust pipe 5 is provided with two arc-shaped baffles 6, forming a funnel-shaped screening space. The exhaust pipe 5 serves as the gas discharge end, allowing air containing light materials to be discharged to the outside of the housing 1. Rotating shafts 10 are fixedly connected to both arc-shaped baffles 6, with seated bearings 11 mounted at both ends of each shaft 10, embedded in the housing 1. Swing rods 12 are fixedly connected to both ends of each rotating shaft 10, located outside the housing 1 and parallel to the arc-shaped baffles 6. Each arc-shaped baffle 6 has a corresponding seated bearing 11, embedded in the housing 1, while the ends of the rotating shafts 10 are rotatably mounted... The two bearings 11 prevent air from leaking out from the gap between the rotating shaft 10 and the housing 1, and the bearings 11 also improve the stability of the rotation of the rotating shaft 10. The housing 1 is equipped with an adjustment component that swings the arc-shaped baffle 6 on the rotating shaft 10 via a swing rod 12. When the arc-shaped baffle 6 rotates on the bearings 11 with the help of the rotating shaft 10, the angle between the arc-shaped baffle 6 and the exhaust pipe 5 can be adjusted, thereby adjusting the size of the funnel-shaped screening space. Moreover, the swing rod 12 is located outside the housing 1, and the swing rod 12 and the arc-shaped baffle 6 are parallel. That is, the rotation angle of the swing rod 12 outside the housing 1 is the same as the rotation angle of the arc-shaped baffle 6 inside the housing 1, which makes it easy to observe the position of the arc-shaped baffle 6 on the exhaust pipe 5. Scale lines can also be sprayed on the surface of the housing 1 to further control the rotation angle of the swing rod 12 and the arc-shaped baffle 6 with greater precision.

[0021] By placing the swing rod 12 and adjustment components outside the outer casing 1, the erosion of related components by particles diffused in the screening chamber is avoided, significantly extending the service life of the equipment. Furthermore, by setting the swing rod 12 parallel to the arc-shaped baffle 6, the rotation angle of the swing rod 12 outside the outer casing 1 is completely consistent with that of the arc-shaped baffle 6 inside, making it easy to visually observe the position of the arc-shaped baffle 6, thereby accurately adjusting the size of the funnel-shaped screen space to adapt to the sorting requirements of materials with different particle sizes.

[0022] Based on the above embodiments, the adjustment component includes two control components 7 and two first drive components 8. The two control components 7 and the two first drive components 8 are symmetrically arranged on both sides of the housing 1. The control components 7 adjust the swing arm 12 by means of the first drive components 8.

[0023] Each arc-shaped baffle 6 consists of two control components 7 and two first drive components 8. The adjustment structure formed by the control components 7 and the first drive components 8 is located on both sides of the arc-shaped baffle 6. When the arc-shaped baffle 6 needs to be adjusted, the two control components 7 need to be adjusted at the same time to complete the angle adjustment of the arc-shaped baffle 6.

[0024] Preferably, the control component 7 includes a fixing plate 71 fixedly connected to the housing 1, a screw 72 slidably connected to the fixing plate 71, a first locking nut 73 and a second locking nut 74 threadedly connected to the screw 72, and the first locking nut 73 and the second locking nut 74 are respectively located on both sides of the fixing plate 71.

[0025] When there are two control components 7, the two fixing plates 71 need to be symmetrically fixed on the two sides of the outer shell 1. The fixing plates 71 are provided with holes that match the screw 72. The screw 72 can slide freely in the holes. After the adjustment is completed, the screw 72 is fixed on the fixing plates 71 by the first locking nut 73 and the second locking nut 74 respectively abutting against the two sides of the fixing plates 71.

[0026] When it is necessary to adjust the swing arm 12, the first locking nut 73 on the two screws 72 should be moved away from the fixed plate 71 at the same time to release the limit on the screws 72.

[0027] Furthermore, two rubber pads are fitted on the screw 72, and the two rubber pads are respectively located between the first locking nut 73 and the fixing plate 71 and the second locking nut 74 and the fixing plate 71.

[0028] Since the friction coefficient of the rubber pad is higher than that of the metal first locking nut 73 and the second locking nut 74, adding rubber pads between the first locking nut 73 and the fixing plate 71 and between the second locking nut 74 and the fixing plate 71 effectively improves the anti-slip effect of the first locking nut 73 and the second locking nut 74 on the screw 72.

[0029] Preferably, the first drive assembly 8 includes a connecting seat 81 fixedly connected to the screw 72, the connecting seat 81 having a rotating groove 82, one end of the swing rod 12 away from the rotating shaft 10 being inserted into the rotating groove 82, the swing rod 12 having an assembly hole 13, and the connecting seat 81 having a connector that connects to the swing rod 12 through the assembly hole 13.

[0030] The connector is located on the connector 81, and the swing rod 12 is rotatably mounted on the connector through the mounting hole 13. When the screw 72 drives the connector 81 to move, the connector 81 can push the swing rod 12 through the rotatable connection between the mounting hole 13 and the connector 81, thereby causing the swing rod 12 to drive the arc-shaped baffle 6 to swing through the rotating shaft 10.

[0031] Furthermore, the connector includes a connecting bolt 84 and two through holes 83 opened on the connecting seat 81, and the through holes 83 are connected to the rotating groove 82. One end of the connecting bolt 84 passes through the through hole 83 and the assembly hole 13 in sequence and is threaded with a connecting nut 85.

[0032] The installation method of the connecting bolt 84 is to insert one end of the swing rod 12 into the interior of the rotating groove 82, align the mounting hole 13 with the through hole 83, then pass one end of the connecting bolt 84 through the through hole 83 and the mounting hole 13 from one side of the connecting seat 81 and extend it from the other side of the connecting seat 81, and then screw the connecting nut 85 onto the connecting bolt 84.

[0033] The system uses detachable 84 connecting bolts for easy maintenance.

[0034] By using a control component 7 with a double locking nut and screw 72, the rubber pad can improve the anti-slip effect of the locking nut, ensure that the screw 72 is firmly fixed, and prevent the arc baffle 6 from shifting after adjustment. The connector adopts a detachable bolt and nut structure, which is convenient for subsequent maintenance and disassembly.

[0035] Preferably, both the first conveying device 2 and the second conveying device 3 are belt conveyors, with the loading end of the first conveying device 2 located outside the outer casing 1 and the unloading end of the first conveying device 2 located above the second conveying device 3.

[0036] The first conveying device 2 and the second conveying device 3 are both composed of a motor, a drive roller, a driven roller and a conveyor belt. The feeding and unloading speeds of the first conveying device 2 and the second conveying device 3 are adjusted by adjusting the speed of the motor.

[0037] The first conveying device 2 conveys the crushed material containing both heavy and light materials to the screening space. After screening, the light material is discharged from the exhaust pipe 5, while the heavy material is fed through the second conveying device 3.

[0038] Furthermore, the discharge end of the second conveying device 3 is located outside the outer casing 1, while the loading end of the second conveying device 3 and the discharge end of the first conveying device 2 are both located within the screening space.

[0039] The material containing both heavy and light materials after crushing is conveyed to the screening space by the first conveying device 2, and then the screened heavy material is discharged from the outer shell 1 by the second conveying device 3.

[0040] Preferably, the air inlet of the blower nozzle 4 is connected to the air supply system or the blower, and the air outlet of the blower nozzle 4 is located below the material discharge end of the first conveying device 2, which is used to separate heavy materials and light materials and blow the light materials into the exhaust pipe 5 for discharge.

[0041] The factory is usually equipped with a centralized air supply system, which supplies air to the blower nozzle 4, so that the blower nozzle 4 blows air to the unloading end of the first conveying device 2, thereby completing the separation of heavy materials and light materials.

[0042] The working principle of this embodiment is as follows: when it is necessary to sort materials, the motors of the first conveying device 2 and the second conveying device 3 are started first, so that the first conveying device 2 and the second conveying device 3 start to run. At the same time, the air supply system or fan is started, so that the air blowing nozzle 4 starts to blow air.

[0043] Materials containing both heavy and light materials are placed at the feeding end of the first conveyor 2. The materials move into the screening space along the conveyor belt of the first conveyor 2. At the discharging end of the first conveyor 2, the materials fall under the action of gravity. At this time, the air blown out by the blower pipe 4 blows the falling materials. Due to the difference in specific gravity between the light and heavy materials, the light materials are blown up by the wind and discharged to the outside of the outer shell 1 through the exhaust pipe 5, while the heavy materials continue to fall onto the second conveyor 3. As the conveyor belt of the second conveyor 3 moves to the outside of the outer shell 1, the separation of heavy and light materials is completed.

[0044] When it is necessary to adjust the angle of the arc-shaped baffle 6 to change the size of the screening space, the first locking nut 73 and the second locking nut 74 on the two screws 72 are moved away from the fixed plate 71 to release the limit on the screws 72. Then, the screws 72 are pushed to slide on the fixed plate 71. The screws 72 drive the connecting seat 81 to move. The connecting seat 81 pushes the swing rod 12 through the connecting piece. The swing rod 12 drives the arc-shaped baffle 6 to swing through the rotating shaft 10. After adjusting to a suitable angle, the first locking nut 73 and the second locking nut 74 are tightened towards the fixed plate 71 so that the rubber pads abut against the two sides of the fixed plate 71 respectively, thus fixing the screws 72 on the fixed plate 71 and fixing the angle of the arc-shaped baffle 6. Example 2

[0045] The difference between this embodiment and Embodiment 1 is that: Figure 5 and Figure 6 As shown, the adjustment component includes a control component 7 and a second drive component 9 disposed in the middle of the housing 1. The control component 7 adjusts the swing of the two swing rods 12 simultaneously through the second drive component 9.

[0046] The control component 7 is located in the middle of the housing 1. The two swing rods 12 can be swung simultaneously by the control component 7 and the second drive component 9, thereby completing the synchronous swing adjustment of the two swing rods 12.

[0047] Furthermore, the second drive assembly 9 includes a fixed base 91 fixedly connected to the screw 72, a linkage shaft 92 fixedly connected to the fixed base 91, and the two ends of the linkage shaft 92 being rotatably connected to two swing rods 12 respectively.

[0048] By connecting the two swing rods 12 through the linkage shaft 92, the screw 72 drives the fixed seat 91, and the fixed seat 91 can synchronously complete the swing adjustment of the two swing rods 12 with the help of the linkage shaft 92, thereby completing the swing adjustment of the arc baffle 6.

[0049] The usage process in this embodiment is as follows: When material sorting is required and the angle of the arc-shaped baffle 6 needs to be adjusted, first release the limit of the control component 7 on the screw 72, move the first locking nut 73 and the second locking nut 74 on the screw 72 away from the fixed plate 71, and then push the screw 72 to slide on the fixed plate 71. The screw 72 drives the fixed seat 91 to move. Since the fixed seat 91 is fixedly connected to the linkage shaft 92, and the two ends of the linkage shaft 92 are respectively rotatably connected to the two swing rods 12, when the fixed seat 91 moves, it will synchronously drive the two swing rods 12 to swing through the linkage shaft 92. The swing rods 12 then drive the arc-shaped baffle 6 to swing through the rotating shaft 10. After adjusting to the appropriate angle, tighten the first locking nut 73 and the second locking nut 74 towards the fixed plate 71, so that the rubber pads abut against the two sides of the fixed plate 71 respectively, thus completing the fixation of the screw 72 on the fixed plate 71, thereby fixing the angle of the two arc-shaped baffles 6.

[0050] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
