Description

Technical Field

[0001] This utility model relates to the field of material conveying device technology, and more specifically, to an air suspension belt conveyor device. Background Technology

[0002] The steel industry is currently facing multiple pressures, including capacity upgrading, green transformation, and market competition. The design of air suspension belts is not only a technical issue, but also a strategic choice for enterprises to reduce costs, increase efficiency, and achieve sustainable development. By extending equipment life and improving reliability, enterprises can build a more efficient, intelligent, and environmentally friendly production system and gain a competitive advantage in the industry transformation.

[0003] In existing technologies, air-suspended belt conveyors are based on aerodynamic principles. They use an air compressor to generate high-pressure airflow, which is then delivered to the exhaust port of the pallet via an air supply pipeline. This creates a uniform air film between the belt and the pallet, transforming the belt's friction from traditional rolling friction to air friction, thus achieving energy savings. However, some problems exist during use. When the air-suspended belt is not in use, it falls onto the pallet, blocking the exhaust port. When the air-suspended belt starts, air is expelled from the exhaust port, which lifts the belt. Because the belt blocks the exhaust port, a large amount of energy is consumed during startup, resulting in waste. Utility Model Content

[0004] The purpose of this invention is to solve the problem of high energy consumption during the start-up of air-suspended belt conveyors, and to design an air-suspended belt conveyor.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: an air-suspended belt conveyor device, comprising an arc-shaped support plate, an arc-shaped conveyor belt above the arc-shaped support plate, and multiple first air storage boxes installed below the arc-shaped support plate. The multiple first air storage boxes are connected by a first connecting pipe. Multiple air outlets are opened at the upper end of the arc-shaped support plate, and the air outlets are located above the first air storage boxes. A support frame is provided on one side of the first air storage box. The support frame can support the arc-shaped conveyor belt after the air supply in the first air storage box is cut off. An air inlet pipe is provided on one side of the first air storage box, and the air inlet pipe can introduce an air source into the first air storage box and the support frame.

[0006] Furthermore, the support frame includes a second gas storage tank installed on one side of the first gas storage tank. Adjacent second gas storage tanks are connected by a second connecting pipe. The arc-shaped support plate has multiple arc-shaped openings located above the second gas storage tanks. An arc-shaped support block is provided inside the arc-shaped opening. A sealing ring is installed inside the arc-shaped opening. Multiple intercepting rods are installed at the lower end of the arc-shaped support block.

[0007] Furthermore, a three-way valve is provided between the first and second gas storage tanks. The inlet end of the three-way valve is connected to the outlet end of the air inlet pipe. An air guide pipe is installed on one side of the first gas storage tank. One outlet end of the three-way valve is connected to the air guide pipe. A one-way valve is installed at one end of the second gas storage tank. The other outlet end of the three-way valve is connected to the inlet end of the one-way valve.

[0008] Furthermore, an exhaust valve is installed at the lower end of the second air storage box, and the arc-shaped support block and the lower inner surface of the second air storage box are connected by a telescopic spring. A limit block is installed at the lower inner end of the second air storage box. The limit block can limit the arc-shaped support block and make the upper surface of the arc-shaped support block and the upper surface of the arc-shaped support plate level when the arc-shaped support block is in the lowest position.

[0009] Furthermore, protective baffles are installed on both sides of the upper surface of the arc-shaped support plate, and multiple rotating rollers are installed on the inner surface of the protective baffles.

[0010] The beneficial effects of this utility model are as follows: When the air suspension belt conveyor is closed, the conveyor belt can be supported by the support frame, which creates a gap between the conveyor belt and the air outlet. This allows air to be quickly discharged from the air outlet when the air suspension belt conveyor is started. After the airflow stabilizes, the support frame can be lowered, and the conveyor belt can then be supported by the airflow, thus achieving energy saving. Attached Figure Description

[0012] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0013] In the description of this utility model, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, in the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0014] This utility model provides, for example Figure 1-4 The air suspension belt conveyor shown includes an arc-shaped support plate 1, an arc-shaped conveyor belt 2 above the arc-shaped support plate 1, and multiple first air storage boxes 3 installed below the arc-shaped support plate 1. The multiple first air storage boxes 3 are connected by a first connecting pipe 4. Multiple air outlets 5 are opened at the upper end of the arc-shaped support plate 1 and are located above the first air storage boxes 3. A support frame 6 is provided on one side of the first air storage box 3. The support frame 6 can support the arc-shaped conveyor belt 2 after the air supply in the first air storage box 3 is cut off. An air inlet pipe 7 is provided on one side of the first air storage box 3, which can introduce air source into the first air storage box 3 and the support frame 6.

[0015] The material conveying process of this device is as follows: Under normal conditions, the support frame 6 does not support the arc-shaped conveyor belt 2. Air is introduced into the first air storage box 3 through the air inlet pipe 7, and then into all the first air storage boxes 3 through the first connecting pipe 4. Finally, the air is discharged through the air outlet 5, which supports the arc-shaped conveyor belt 2 and reduces the friction when the arc-shaped conveyor belt 2 moves, thus achieving energy saving. When the air suspension belt conveyor is turned off, the air in the air inlet pipe 7 is introduced into the support frame 6, which facilitates the support of the arc-shaped conveyor belt 2. Then, the air source in the first air storage box 3 is cut off. At this time, there is a gap between the arc-shaped conveyor belt 2 and the air outlet 5. When the air suspension belt conveyor is restarted, air can be introduced into the first air storage box 3 through the air inlet pipe 7 and then discharged through the air outlet 5. Since there is a gap above the air outlet 5, the resistance when the air is discharged is reduced. After the airflow stabilizes, the support frame 6 is retracted to achieve the purpose of energy saving.

[0016] Refer to the instruction manual appendix Figure 2 Included with instruction manual Figure 3 The support frame 6 includes a second gas storage box 8 installed on one side of the first gas storage box 3. Adjacent second gas storage boxes 8 are connected by a second connecting pipe 9. The arc-shaped support plate 1 has multiple arc-shaped openings 10. The arc-shaped openings 10 are located above the second gas storage boxes 8. An arc-shaped support block 11 is provided inside the arc-shaped opening 10. A sealing ring 12 is installed inside the arc-shaped opening 10. Multiple intercepting rods 13 are installed at the lower end of the arc-shaped support block 11.

[0017] The process of the support frame 6 supporting the arc-shaped conveyor belt 2 is as follows: Under normal conditions, the arc-shaped support block 11 is located inside the arc-shaped opening 10. When it is necessary to support the arc-shaped conveyor belt 2, air is introduced into the second air storage box 8, which increases the air pressure inside the second air storage box 8, thereby allowing the arc-shaped support block 11 to move upward, and then the arc-shaped conveyor belt 2 can be supported. The sealing ring 12 can prevent air leakage, and the intercepting rod 13 can limit the arc-shaped support block 11 to prevent the arc-shaped support block 11 from moving outside the arc-shaped opening 10.

[0018] Refer to the instruction manual appendix Figure 4 A three-way valve 14 is installed between the first air storage tank 3 and the second air storage tank 8. The inlet end of the three-way valve 14 is connected to the outlet end of the air inlet pipe 7. An air guide pipe 15 is installed on one side of the first air storage tank 3. One outlet end of the three-way valve 14 is connected to the air guide pipe 15. A one-way valve 16 is installed at one end of the second air storage tank 8. The other outlet end of the three-way valve 14 is connected to the inlet end of the one-way valve 16. Under normal conditions, the three-way valve 14 is connected to the first air storage tank 3, allowing air to be discharged from the air outlet 5 and supporting the arc-shaped conveyor belt 2. When it is necessary to shut down the air suspension belt conveyor, the three-way valve 14 is disconnected from the first air storage tank 3 and connected to the one-way valve 16, which allows air to be discharged into the second air storage tank 8. This increases the air pressure in the second air storage tank 8, facilitating the upward movement of the arc-shaped support block 11. Then, the air supply to the air inlet pipe 7 is stopped, and the one-way valve 16 prevents air leakage.

[0019] Refer to the instruction manual appendix Figure 2An exhaust valve 17 is installed at the lower end of the second air storage box 8. The arc-shaped support block 11 and the lower inner surface of the second air storage box 8 are connected by a telescopic spring 18. A limit block 19 is installed at the lower inner end of the second air storage box 8. The limit block 19 can limit the arc-shaped support block 11 so that when the arc-shaped support block 11 is in the lowest position, the upper surface of the arc-shaped support block 11 is flush with the upper surface of the arc-shaped support plate 1. When the arc-shaped support block 11 moves upward, the telescopic spring 18 can be stretched. When it is necessary to return the arc-shaped support block 11 to its original position, the exhaust valve 17 is opened to allow the air in the second air storage box 8 to be discharged. Then, under the pulling force of the telescopic spring 18, the arc-shaped support block 11 returns to its original position. The limit block 19 can limit the arc-shaped support block 22 to ensure its position.

[0020] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 2 Included with instruction manual Figure 3 The upper surface of the arc-shaped support plate 1 is equipped with protective baffles 20 on both sides. Multiple rotating rollers 21 are installed on the inner surface of the protective baffles 20. The protective baffles 20 and rotating rollers 21 can prevent the arc-shaped conveyor belt 2 from running off-center. The rotating rollers 21 can rotate, which can reduce the friction when the arc-shaped conveyor belt 2 contacts the rotating rollers 21, thus preventing damage to the arc-shaped conveyor belt 2.

[0021] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
