[0042] The present application proposes a pipeline air suspension conveyor. Specifically, the pipeline air suspension conveyor is a closed pipeline air suspension conveyor.

[0043] The pipeline air suspension conveyor includes a conveying body, frames (not shown) arranged at both ends of the conveying body, and a conveying belt 300 .

[0044] A driving device (not shown) is fixed on the frame. The driving device specifically includes a driving motor and a conveying roller group. The driving motor and the conveying roller group are connected to the frame.

[0045] The conveying roller group specifically includes a first roller group and a second roller group arranged at two ends of the conveying body, and the two ends of the conveying belt 300 are rotatably connected to the first roller group and the second roller group respectively.

[0046] refer to Figure 1 The conveying body includes at least one conveying unit 100. Due to the long conveying distance, the conveying body generally includes a plurality of conveying units 100 connected in the first place.

[0047] The conveying chamber 101 , the conveying air chamber 102 , the return chamber 103 and the return air chamber 104 among the conveying units 100 are interconnected.

[0048] A conveying chamber 101 , a conveying air chamber 102 , a return chamber 103 and a return air chamber 104 are formed on the conveying unit 100 . The conveying air chamber 102 is communicated with the conveying chamber 101 , and the return air chamber 104 is communicated with the return chamber 103 .

[0049] Supporting uprights are provided at least at two ends of the conveying unit 100 , and the supporting uprights are vertically supported at two ends of the return air chamber 104 , so as to improve the structural strength of the conveying unit and provide auxiliary support for the conveying air chamber 102 above the return air chamber 104 .

[0050] The material is placed on the conveyor belt 300 from the conveying start end where the first roller group is located, and is conveyed to the conveying end through the conveying chamber 101. After passing through the second roller group at the conveying end, the conveyor belt 300 is returned from the return chamber 103 for cyclic conveying.

[0051] A fan component is fixed on at least part of the conveying unit 100, and the fan component is connected to the conveying chamber 101. A connecting pipe 170 is also provided between the conveying chamber 101 and the return chamber 103 of each conveying unit 100, and the connecting pipe 170 is used to connect the conveying chamber 101 and the corresponding return chamber 103.

[0052] The bottom of the delivery air chamber 102 and the return air chamber 104 are dispersedly formed with a plurality of air holes (not shown), and the airflow output by the fan component passes through the delivery air chamber 102 and the return air chamber 104 and is respectively input into the delivery chamber 101 and the return chamber 103 .

[0053] Then, air cushion supports are formed between the conveyor belt 300 in the conveying chamber 101 and the bottom of the conveying chamber 101 , and between the conveyor belt 300 in the return chamber 103 and the bottom of the return chamber 103 .

[0054] The fan delivers pressurized gas to the corresponding conveying chamber 101 or return chamber 103, thereby supporting the conveyor belt 300 and the materials.

[0055] The conveyor belt 300 passes around the first roller group and the second roller group. The material is transported to the conveyor belt 300 through the feeding device and then transported to the target position as the conveyor belt 300 passes through the conveying chamber 101. The conveyor belt 300 is then turned over to realize unloading, and the driving motor is used as the power to realize continuous material transportation.

[0056] The conveying chamber 101 as a whole is a horizontally extending cylindrical chamber, and the conveyor belt 300 in the conveying chamber 101 is also a concave structure with a low middle and high sides. Therefore, problems such as material falling during transportation can be avoided, and safety and cleanliness are greatly improved.

[0057] The pipeline air suspension conveyor does not require rollers during transportation. It relies on the continuous air film to support the conveyor belt to achieve continuous transportation of materials.

[0058] The conveying chamber 101 of the pipeline air suspension conveyor is cylindrical, and the conveyor belt in the conveying chamber 101 is an arc-shaped structure. The conveyor belt 300 does not deviate, and the materials are concentrated in the middle position of the conveyor belt 300. The sealing structure of the conveying chamber 101 effectively avoids dust and overflow problems, realizes safe operation, and is conducive to reducing dust particles and other pollution to the surrounding environment.

[0059] The conveyor belt 300 is suspended on the air film, with extremely low running resistance, which can save ≥40% of the driving power compared with the roller conveyor.

[0060] The air suspension film formed between the conveyor belt 300 and the conveying chamber 101 has a small friction coefficient, and the life cycle of the conveyor belt 300 is extended to 2-3 times.

[0061] refer to Figure 2 A photovoltaic component is also provided on the conveying body. The photovoltaic component includes a photovoltaic panel 200 laid on the surface of the conveying body and a power storage system connected to the photovoltaic panel 200. The energy generated by the photovoltaic panel 200 under the action of light is stored in the storage component and converted into electrical energy in the storage component. The power storage system is connected to the drive motor through the control system to supply power to the drive motor.

[0062] In some embodiments of the present application, an arc-shaped installation surface 105 is formed on the upper surface of each conveying unit 100 , and the photovoltaic panel 200 is laid on the installation surface 105 .

[0063] The mounting surface 105 is an arc-shaped structure, which is beneficial to increasing the use area of ​​the photovoltaic panel 200 and improving the power generation efficiency.

[0064] Photovoltaic modules generate electricity and store it during the day, and discharge it at night to be self-sufficient.

[0065] In some embodiments of the present application, the photovoltaic panel 200 is fixed to the transport unit 100 by plugging.

[0066] Specifically, plug-in slots 120 are respectively provided on both sides of the mounting surface 105 , and plug-in portions 210 corresponding to the positions of the plug-in slots 120 are formed on both sides of the photovoltaic panel 200 , and the photovoltaic panel 200 is fixed on the plug-in slots 120 through the plug-in portions 210 .

[0067] Furthermore, in order to improve the stability of the connection, a through-hole structure is formed at the bottom of the plug-in slot 120, and a buckle extending outward is formed at the bottom of the plug-in portion 210. When connected, the plug-in portion 210 is connected to the corresponding plug-in slot 120, and the buckle passes through the through-hole structure and is clamped at the bottom of the plug-in slot 120. This prevents the plug-in portion 210 from falling out of the plug-in slot 120, which is beneficial to improving the stability of the connection.

[0068] The number of the insertion slots 120 and the insertion portions 210 is determined according to the actual length of the conveying unit 100 .

[0069] In other embodiments, the photovoltaic panel 200 may also be fixed to the transport unit 100 via a connecting frame or other structure.

[0070] The connecting frame is specifically a frame structure welded on the mounting surface 105 of the conveying unit 100 . The photovoltaic panel 200 is fixed to the connecting frame by steel wires or other connecting parts, and the connection and fixation between the photovoltaic panel 200 and the conveying unit 100 can also be achieved.

[0071] refer to Figure 3-Figure 5 , adjacent conveying units 100 are connected by fasteners.

[0072] Specifically, a connecting outer edge 140 is formed at both ends of each conveying unit 100 , and a plurality of connecting holes 160 are dispersedly provided on the connecting outer edge 140 . The connecting outer edges 140 of adjacent conveying units 100 are connected by fasteners.

[0073] The connecting outer edge 140 is specifically formed on the peripheral side of the conveying unit 100 to connect and fix the peripheral sides of adjacent conveying units 100 .

[0074] Since the conveying air chamber 102 is located below the conveying chamber 101 and the return air chamber 104 is located below the return chamber 103, in order to seal the conveying air chamber 102 and the return chamber 103 and prevent the airflow in the conveying chamber 101 from being conveyed downward from the connection gap position to the return chamber 103, a sealing outer edge 150 is also provided between the conveying air chamber 102 and the return chamber 103, and a plurality of connection holes 160 are dispersedly formed on the sealing outer edge 150, and adjacent sealing outer edges 150 are connected by fasteners.

[0075] Furthermore, in some embodiments of the present application, seals are provided between adjacent conveying units 100 to further seal the conveying body and the outside, and between the conveying air chamber 102 and the return chamber 103 .

[0076] The sealing member is specifically made of rubber material. A sealing groove is formed on the contact surface of adjacent conveying units 100. The sealing member is connected in the sealing groove to seal the gap between the conveying units 100 to avoid problems such as airflow leakage.

[0077] A fan flange 130 is formed on at least a portion of the conveying unit 100 . The fan flange 130 is in communication with the conveying air chamber 102 , and the fan component is mounted on the fan flange 130 .

[0078] The wind turbine is also connected to the photovoltaic module. Under the control of the control system, the photovoltaic module can provide electrical energy for the drive motor and the wind turbine.

[0079] A part of the airflow formed by the wind piece enters into the conveying air chamber 102, and a part of the airflow is conveyed into the conveying chamber 101 through the air holes between the conveying air chamber 102 and the conveying chamber 101, so as to support the conveyor belt 300 and the materials.

[0080] Another part of the airflow is transported to the return air chamber 104 through the connecting pipe 170, and then transported to the return chamber 103 through the air holes between the return air chamber 104 and the return chamber 103, so as to provide support for the conveyor belt 300 during the return process.

[0081] The air cushion formed between the conveyor belt 300 and the conveyor body is beneficial to reducing the friction between the conveyor belt 300 and the conveyor body, reducing the wear of the conveyor belt 300, and is also beneficial to improving the conveying speed and efficiency, thereby ensuring the service life of the equipment and reducing maintenance.

[0082] Since the friction between the conveyor belt 300 and the conveying chamber 101 and the return chamber 103 is reduced, even when the conveyor belt 300 is fully loaded with materials, the driving motor can easily start the conveyor belt 300 for transmission.

[0083] The conveyor belt 300 in the conveying inner cavity is in an arc shape, and the curvature of the conveyor belt 300 in the return chamber 103 is smaller than the curvature of the conveyor belt 300 in the conveying inner cavity.

[0084] Correspondingly, the first roller group located on one side of the conveying body specifically includes an active roller, a grooved upper roller and a parallel lower roller. The active roller is connected to the output end of the driving motor, the grooved upper roller is located between the active roller and the conveying body, the grooved upper roller is height-matched with the conveying chamber 101, and the parallel lower roller is position-matched with the grooved upper roller.

[0085] The second roller group located on the other side of the conveying body includes a driven roller, a grooved upper roller and a parallel lower roller. The grooved upper roller in the second roller group is located between the driven roller and the conveying body. The grooved upper roller is height-matched with the conveying chamber 101, and the parallel lower roller is position-matched with the grooved upper roller. The two ends of the conveyor belt 300 are respectively connected to the active roller and the driven roller.

[0086] The two ends of the upper conveyor belt 300 for conveying materials form an arc shape that matches the arc of the conveying chamber 101 under the action of the grooved upper rollers, which is used to hold materials, reduce the materials falling from both sides of the conveyor belt 300, and improve the stability during the conveying process.

[0087] After the material is transported to the target location for unloading, the conveyor belt 300 is formed into a shape that matches the curvature of the return chamber 103 under the action of the parallel lower rollers and transported back.

[0088] The support and position of the active roller, the grooved upper roller and the parallel lower roller are realized through the frame, and the support and specific position arrangement of the driven roller, the grooved upper roller and the parallel lower roller are realized through the frame on the other side.

[0089] The pipeline air suspension conveyor involved in this application achieves self-sufficiency in electricity through the photovoltaic components installed thereon, reduces the laying of transmission wires, etc., is safer, and saves energy.

[0090] The sealed structure of the pipeline air suspension conveyor is conducive to reducing the risk of material falling, which is safer and helps to reduce dust particles and other pollution to the surrounding environment. It does not scatter materials or raise dust. The overall equipment has good stability and the conveying route is accurate and does not deviate.
