Description

Technical Field

[0001] This utility model relates to the field of powder conveying technology, and in particular to a powder conveying pipeline. Background Technology

[0002] Pipeline transportation, with its significant advantages of high efficiency, land saving, economy, and environmental friendliness, has become the most widely used transportation mode in modern industry. This mode is based on the principles of fluid dynamics, utilizing high-speed, high-pressure fluid to propel materials forward within a closed pipeline. However, during pipeline transportation, powder particles often accumulate on the inner wall of the pipeline due to factors such as differences in particle flowability, pipeline geometry (e.g., the number of bends, improper bending angles, abrupt changes in pipe diameter), and airflow velocity control, forming a dust accumulation layer. This phenomenon not only increases pipeline flow resistance but also poses a potential risk of deflagration. Once the dust accumulation layer reaches a critical thickness and encounters triggering conditions such as high temperature or open flame, a deflagration accident is highly likely. Dust explosions not only possess the power of an initial explosion but may also trigger secondary explosions, further exacerbating the destructive effects. The resulting shock waves and high-temperature flames can cause catastrophic damage to pipeline systems, production equipment, and even the entire production chain.

[0003] Existing technology CN220536928U discloses a powder conveying pipeline structure, including a powder conveying pipe, a main conveying air passage formed inside the powder conveying pipe, and a side air passage branching off from the upper part of the powder conveying pipe. The side air passage obliquely penetrates from the outside of the powder conveying pipe into the powder conveying pipe and is tangential to the main conveying air passage. After tangency, the side air passage merges with the main conveying air passage. In this utility model, the side air passage branching off from the powder conveying pipe can be opened when powder deposition occurs in the powder conveying pipe and the main conveying air passage is not running smoothly. The side air passage is opened, and the airflow is obliquely blown from the side of the powder conveying pipe into the powder conveying pipe. This can both disperse the settled and deposited powder, reduce the resistance of the main conveying air passage, and supplement the conveying energy of the main conveying air passage, increase the conveying pressure, and enable the main conveying air passage to continue to maintain the conveying flow rate, preventing powder particles from settling. The entry of the side air passage solves the problem of powder deposition and also prevents the occurrence of powder deposition phenomenon.

[0004] Regarding the aforementioned powder conveying pipeline structure, although the airflow impact of the nozzle can break up the deposited powder and thus remove the powder deposit, the nozzle is fixed and the airflow direction can only be in a specific direction, which limits the cleaning range and affects the cleaning effect. Utility Model Content

[0005] The purpose of this invention is to provide a powder conveying pipe that solves the problem that although the existing technology can break up the deposited powder by using the airflow impact of the air nozzle, thereby removing the powder deposit, the air nozzle is fixed and the airflow direction can only be in a specific direction, which limits the cleaning range and affects the cleaning effect.

[0006] To achieve the above objectives, this utility model provides a powder conveying pipe, including a main conveying pipe, an inclined side pipe, an air nozzle body, and an adjusting assembly. The inclined side pipe is fixedly connected to and communicates with the main conveying pipe. The air nozzle body is fixedly installed on the inclined side pipe. The adjusting assembly includes a first connecting rod, a second connecting rod, an air inlet cup, an air nozzle, and a control component. The first connecting rod is rotatably connected to the inclined side pipe and located inside the inclined side pipe. The second connecting rod extends into the inclined side pipe and is rotatably connected to it. The air inlet cup is connected to both the first and second connecting rods and is located inside the inclined side pipe. The air nozzle is fixedly installed on the air inlet cup and located outside the air inlet cup. The control component controls the rotation of the second connecting rod.

[0007] The control component includes a worm gear, a worm, and a drive motor. The worm gear is fixedly connected to the second connecting rod and is located at the end of the second connecting rod away from the air inlet. The worm is rotatably mounted on the inclined side tube and meshes with the worm gear. The drive motor is mounted on the outside of the inclined side tube, and the output shaft of the drive motor is fixedly connected to the worm.

[0008] The control component further includes a protective cover, which is detachably connected to the inclined side tube and located on the side of the inclined side tube near the worm gear.

[0009] The adjustment assembly further includes a rubber hopper, which is fixedly connected to the air receiving bowl and located on the side of the air receiving bowl away from the air nozzle.

[0010] The adjustment component further includes a limiting pin, which is fixedly connected to the air inlet bowl and located on the outer periphery of the air inlet bowl.

[0011] This utility model discloses a powder conveying pipe, comprising a main conveying pipe, an inclined side pipe, an air nozzle body, and an adjusting assembly. The inclined side pipe is fixedly connected to and communicates with the main conveying pipe. The air nozzle body is fixedly installed on the inclined side pipe. The adjusting assembly includes a first connecting rod, a second connecting rod, an air inlet cup, an air nozzle, and a control component. The first connecting rod is rotatably connected to the inclined side pipe and located inside the inclined side pipe.

This invention solves the problem that although existing technologies can use the airflow impact of the air nozzle to disperse deposited powder and thus remove it, the air nozzle is fixed, and the airflow direction can only be in a specific direction, resulting in a limited cleaning range and affecting the cleaning effect.

[0018] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0019] The embodiment of this application is as follows:

[0020] Please see Figures 1-4 , Figure 1 This is a schematic diagram of the overall structure of the powder conveying pipeline of this utility model. Figure 2 This is a schematic diagram of the internal structure of the inclined side tube 102 of this utility model. Figure 3 This is a structural schematic diagram of the air inlet bowl 106 of this utility model. Figure 4 This is a schematic diagram of the control component of this utility model.

[0021] This utility model discloses a powder conveying pipeline, comprising a main conveying pipe 101, an inclined side pipe 102, an air nozzle body 103, a first connecting rod 104, a second connecting rod 105, an air receiving bowl 106, an air nozzle 107, a worm gear 108, a worm 109, a drive motor 110, a protective cover 111, a rubber hopper 112, and a limiting pin 113. It solves the problem that while existing technologies utilize the airflow impact of the air nozzle to disperse deposited powder and thus remove it, the air nozzle is fixed, and the airflow direction can only be directed in a specific direction, resulting in a limited cleaning range and affecting the cleaning effect. It is understood that the aforementioned solution can further improve the unblocking effect.

[0022] In this embodiment, the main conveying pipe 101, the inclined side pipe 102, and the air nozzle body 103 are all prior art, and the result refers to the prior art CN220536928U, a powder conveying pipeline structure. The adjusting component is installed on the inclined side pipe 102, thereby solving the problem that although the prior art can use the airflow impact of the air nozzle to disperse the deposited powder and thus remove the powder deposit, the air nozzle is fixed and the airflow direction can only be in a specific direction, which limits the cleaning range and affects the cleaning effect.

[0023] The first connecting rod 104 is rotatably connected to the inclined side tube 102 and located inside the inclined side tube 102. The second connecting rod 105 extends into the inclined side tube 102 and is rotatably connected to it. The air inlet cup 106 is connected to both the first connecting rod 104 and the second connecting rod 105 and is located inside the inclined side tube 102. The air nozzle 107 is fixedly installed on the air inlet cup 106 and located on its outer side. The control component controls the rotation of the second connecting rod 105. The first connecting rod 104 is mounted on the inner wall of the inclined side tube 102 via a bearing and is located inside the inclined side tube 102. The second connecting rod 105 extends into the inclined side tube 102 from the side opposite to the first connecting rod 104 and is connected to the inclined side tube 102 via a sealed bearing. The air inlet cup 106 is a bowl-shaped structure and is located between the first connecting rod 104 and the second connecting rod 105. The air receiving bowl 106 is fixedly connected to the ends of the first connecting rod 104 and the second connecting rod 105, allowing it to rotate within the inclined side pipe 102. The concave surface of the air receiving bowl 106 faces the air outlet of the air nozzle body 103. The air nozzle 107 is connected to the air receiving bowl 106. The air receiving bowl 106 gathers the air blown out by the air nozzle body 103 and then sprays it out towards the conveying main pipe 101 through the air nozzle 107. The control component can drive the second connecting rod 105 to rotate. The rotation of the second connecting rod 105 drives the air receiving bowl 106 to rotate, thereby driving the air nozzle 107 to rotate, thus changing the airflow angle. This allows for better dispersion of accumulated powder, improving the unblocking effect. It solves the problem that although the existing technology can disperse deposited powder by using the airflow impact of the air nozzle, thereby removing the powder deposit, the air nozzle is fixed and the airflow direction can only be in a specific direction, resulting in a limited cleaning range and affecting the cleaning effect.

[0024] Secondly, the worm gear 108 is fixedly connected to the second connecting rod 105 and is located at the end of the second connecting rod 105 away from the air inlet 106; the worm 109 is rotatably mounted on the inclined side tube 102 and meshes with the worm gear 108; the drive motor 110 is mounted on the outside of the inclined side tube 102, and the output shaft of the drive motor 110 is fixedly connected to the worm 109. The worm 109 is sleeved on the end of the second connecting rod 105 located on the inclined side tube 102. The worm 109 is mounted on the outside of the inclined side tube 102 through a bearing bracket. The drive motor 110 is fixed to the outside of the inclined side tube 102 by bolts and is used to drive the worm 109 to rotate. The drive motor 110 is equipped with a matching controller. Through the controller, the drive motor 110 can be made to operate according to a set direction, speed, and time. Through the operation of the drive motor 110, the second connecting rod 105 is driven to rotate under the transmission of the worm 109 and the worm gear 108.

[0025] Meanwhile, the protective cover 111 is detachably connected to the inclined side tube 102 and is located on the side of the inclined side tube 102 near the worm 109. The protective cover 111 is installed on the outside of the inclined side tube 102 by bolts, covering the worm wheel 108 and the worm 109. The protective cover 111 can play a protective role, thereby improving safety.

[0026] In addition, the rubber hopper 112 is fixedly connected to the air receiving bowl 106 and is located on the side of the air receiving bowl 106 away from the air nozzle 107. The rubber hopper 112 is funnel-shaped and made of rubber material. It is installed at the opening of the air receiving bowl 106. Through the rubber hopper 112, the air receiving bowl 106 can better collect the gas blown out by the air nozzle body 103.

[0027] Finally, the limiting pin 113 is fixedly connected to the air receiving bowl 106 and is located on the outer periphery of the air receiving bowl 106. There are two limiting pins 113, which are symmetrically arranged on the outer side of the air receiving bowl 106 to limit the rotation angle of the air receiving bowl 106. Through the limiting pins 113, the excessive rotation of the air receiving bowl 106 can be avoided.

[0028] In this embodiment, when unblocking is required, the air nozzle body 103 blows gas under the action of an external air source. The air receiving bowl 106 gathers the gas blown away by the air nozzle body 103 and sprays it out through the air nozzle 107. The gas sprayed out by the air nozzle can directly act on the conveying main pipe 101 to disperse the powder accumulated on the inner wall of the conveying main pipe 101, thereby unblocking. During the unblocking process, the drive motor 110 performs regular forward and reverse rotation according to the set parameters under the action of the controller, driving the second connecting rod 105 to rotate. The air receiving bowl 106 is connected to the second connecting rod 105 and rotates back and forth, thereby causing the air nozzle 107 to swing and emit air. Compared with the prior art, the range of action is larger, and the accumulated powder can be cleaned better. This solves the problem that although the prior art can use the airflow impact of the air nozzle to disperse the deposited powder and thus remove the powder deposit, the air nozzle is fixed and the airflow direction can only be in a specific direction, which limits the cleaning range and affects the cleaning effect.

[0029] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
