Description

Technical Field

[0001] This utility model relates to the field of chemical production equipment technology, specifically to a conveying pipeline and an automated material particle conveying equipment. Background Technology

[0002] In the continuous production of high-end polyolefins (EPOE), the material particle conveying process is crucial. Automated material particle conveying technology aims to efficiently and stably transport polyolefin particles generated in the reactor to subsequent processing stages. This technology involves interdisciplinary knowledge from mechanical engineering, pneumatic conveying principles, and automation control. By optimizing the structure and operation of the conveying equipment, it ensures that the polyolefins maintain good physical properties during conveying, meeting the production requirements of high-end polyolefin products and improving overall production efficiency and product quality.

[0003] Traditional polyolefin particle conveying systems mostly employ simple pneumatic conveying pipelines, where polyolefin particles are propelled forward in a straight line by airflow. These pipelines typically have a simple structure, relying solely on high airflow pressure to overcome the resistance encountered during transport, resulting in relatively low particle conveying efficiency. Utility Model Content

[0004] In view of this, the present invention provides a conveying pipeline and an automated material particle conveying device to solve the problem of low material particle conveying efficiency caused by the simple structure of the conveying pipeline.

[0005] In a first aspect, this utility model provides a conveying pipeline, comprising:

[0006] delivery pipe;

[0007] The rectifier, in multiple forms, is detachably disposed inside the conveying pipe and extends along the axial direction of the conveying pipe;

[0008] The rectifier plate extends spirally along the axial direction of the conveying pipe.

[0009] In this application, the rectifier plate guides the material particles within the conveying pipe, transforming the linear flow in the prior art into a rotating forward flow. This rotating flow increases the contact area and mixing degree between the material particles and the air, resulting in a more uniform distribution of the material particles in the airflow. This reduces collisions and accumulation between material particles, lowers conveying resistance, and thus improves the conveying efficiency of the material particles.

[0010] In one optional embodiment, the two ends of the conveying pipe are provided with connectors, and two adjacent conveying pipes are detachably connected by the connectors.

[0011] In this application, the conveying pipe is detachably connected by connectors, and multiple sets of conveying pipes can be connected to form conveying pipes of the required length. When the rectifier plate is worn or needs cleaning, it can be quickly disassembled for processing, reducing equipment downtime, lowering maintenance costs, and ensuring the long-term stable operation of the conveying system.

[0012] In one alternative embodiment, a rectifier tube is fitted inside the delivery pipe, and the rectifier plate is disposed inside the rectifier tube.

[0013] In this application, the rectifier tube allows material particles to directly contact and rub against the rectifier tube, avoiding damage to the conveying tube by the material particles. During maintenance and cleaning, the rectifier tube can be directly disassembled for maintenance, cleaning, and replacement.

[0014] In one alternative embodiment, the rectifier has a retaining block extending along the rectifier, and the rectifier tube has a mounting groove that matches the retaining block;

[0015] The card block is slidably disposed in the mounting groove, which is used to limit the card block circumferentially and radially.

[0016] In this application, the rectifier can be inserted or removed along the extension direction of the mounting groove, enabling detachable installation of the rectifier and facilitating its inspection, cleaning, and replacement. This also prevents the rectifier from detaching from the rectifier tube in the circumferential and radial directions.

[0017] In one optional embodiment, a blocking plate is provided between two adjacent conveying pipes, and when the two adjacent conveying pipes are connected, the blocking plate is fixed between the two connecting parts;

[0018] The blocking plate is suitable for axially limiting the rectifier plate and rectifier tube.

[0019] In this application, when two adjacent delivery pipes are connected, the blocking plate can confine the rectifier plate and the rectifier pipe inside the delivery pipe.

[0020] In one alternative embodiment, the surface of the rectifier has a plurality of arc-shaped grooves.

[0021] In this application, the arc-shaped groove can disrupt the airflow boundary layer, reduce the drag force of the airflow on the material particles, reduce the air resistance during the movement of the material particles, and further improve the conveying speed of the material particles. Through the synergistic effect of the rectifier and the arc-shaped groove, the conveying efficiency of the material particles in the conveying pipe is effectively improved, and the generated material particles can be conveyed to the destination more quickly and stably, reducing the conveying time and improving production efficiency.

[0022] In one alternative embodiment, the outer diameter of the rectifier tube is the same as the inner diameter of the delivery tube. This prevents the rectifier tube from swaying within the delivery tube.

[0023] In one optional embodiment, the blocking plate is an annular plate, and the inner diameter of the blocking plate is the same as the inner diameter of the rectifier tube. This allows for axial positioning of the rectifier blades and the rectifier tube.

[0024] In one alternative embodiment, the rectifier plates are uniformly arranged circumferentially on the inner side of the rectifier tube. This allows for a more uniform distribution of material particles in the airflow.

[0025] Secondly, this utility model also provides an automated material particle conveying device, comprising:

[0026] Such as the aforementioned delivery pipelines;

[0027] The reactor is connected to the conveying pipeline;

[0028] An airflow device, connected to the delivery pipe and adapted to provide airflow to the delivery pipe in a direction away from the reactor. Attached Figure Description

[0037] 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.

[0038] In the continuous production of high-end polyolefins (EPOE), material handling is crucial. Automated material handling technology aims to efficiently and stably transport polyolefin particles generated in the reactor to subsequent processing stages. This technology involves interdisciplinary knowledge from mechanical engineering, pneumatic conveying principles, and automation control. By optimizing the structure and operation of conveying equipment, it ensures that polyolefins maintain good physical properties during transport, meeting the production requirements of high-end polyolefin products and improving overall production efficiency and product quality.

[0039] Traditional polyolefin material conveying mostly employs simple pneumatic conveying pipeline systems, where polyolefin particles are propelled forward in a straight line by airflow within the pipeline. The conveying pipelines are typically structurally simple, lacking internal rectification or guiding devices, relying solely on high airflow pressure to overcome the resistance of the particles during transport. In terms of installation and maintenance, the components of traditional conveying equipment are mostly fixed connections. If internal parts wear out or require cleaning, it often necessitates a significant amount of time to disassemble the entire conveying system, making operation cumbersome and inconvenient.

[0040] The following is combined Figures 1 to 5 The following describes embodiments of the present invention.

[0041] Example 1

[0042] This utility model provides a conveying pipeline, such as Figures 1 to 5 As shown, it includes:

[0043] Delivery pipe 1;

[0044] The rectifier 2, in multiple forms, is detachably disposed inside the conveying pipe 1 and extends along the axial direction of the conveying pipe 1;

[0045] The rectifier plate 2 extends spirally along the axial direction of the conveying pipe 1.

[0046] In this application, the rectifier 2 guides the material particles in the conveying pipe 1, transforming the linear flow in the prior art into a rotating forward flow. This rotating flow increases the contact area and mixing degree between the material particles and the air, making the material particles more evenly distributed in the airflow, reducing mutual collisions and accumulation between material particles, lowering the conveying resistance, and thus improving the material particle conveying efficiency.

[0047] In one alternative implementation, such as Figure 2 As shown, the conveying pipe 1 has connectors at both ends, and two adjacent conveying pipes 1 are detachably connected by the connectors. The connector can be a flange 9, and two adjacent conveying pipes 1 are connected by flanges 9. The flanges 9 at both ends of the conveying pipe 1 can be integrally formed with the conveying pipe 1. Multiple adjacent sets of conveying pipes 1 can be connected sequentially by flanges 9 and fasteners such as bolts. The conveying pipe 1 is fixedly connected to the output end of the reactor 8, and the polyolefin particles generated by the reactor 8 are pneumatically conveyed through the conveying pipe 1.

[0048] In this application, the conveying pipe 1 is detachably connected by a connector, and multiple sets of conveying pipe 1 can be connected to form conveying pipe 1 with the required length. When the rectifier plate 2 is worn or needs to be cleaned, it can be quickly disassembled for processing, reducing equipment downtime, lowering maintenance costs, and ensuring the long-term stable operation of the conveying system.

[0049] In one alternative implementation, such as Figure 3 As shown, a rectifier tube 3 is fitted inside the conveying pipe 1, and the rectifier plate 2 is disposed inside the rectifier tube 3. The rectifier tube 3 can be a long circular tube.

[0050] In this application, the rectifier tube 3 allows material particles to directly contact and rub against the rectifier tube 3, avoiding damage to the conveying tube 1 caused by the material particles. During maintenance and cleaning, the rectifier tube 3 can be directly disassembled for maintenance, cleaning, and replacement.

[0051] In one alternative implementation, such as Figure 3 and Figure 4 As shown, the rectifier 2 has a retaining block 4 extending along it, and the rectifier tube 3 has a mounting groove 5 that matches the retaining block 4. The retaining block 4 can be a dovetail structure or a convex structure, and its thickness can be greater than that of the rectifier 2, and it is adapted to the mounting groove 5. The retaining block 4 is engaged in the mounting groove 5. The thickness of the retaining block 4 can be 1.1 to 1.5 times the thickness of the rectifier 2, specifically 1.2 times. It should be noted that this embodiment is not limited to this.

[0052] The card block 4 is slidably disposed in the mounting groove 5, and the mounting groove 5 is used to limit the card block 4 in both the circumferential and radial directions.

[0053] In this application, the rectifier 2 can be inserted or removed along the extension direction of the mounting groove 5, enabling the rectifier 2 to be detachably installed. This facilitates the inspection, cleaning, and replacement of the rectifier 2. It also prevents the rectifier 2 from detaching from the rectifier tube 3 in the circumferential and radial directions.

[0054] In one alternative implementation, such as Figure 2 As shown, a blocking plate 6 is provided between two adjacent conveying pipes 1. When the two adjacent conveying pipes 1 are connected, the blocking plate 6 is fixed between the two connecting parts. The blocking plate 6 can be provided with screw holes. When the two flanges 9 are connected, the bolts can pass through the screw holes on the flanges 9 and the blocking plate respectively to make the connection.

[0055] The blocking plate 6 is suitable for axially limiting the rectifier plate 2 and the rectifier tube 3.

[0056] In this application, when two adjacent conveying pipes 1 are connected, the blocking plate 6 can limit the rectifier plate 2 and the rectifier pipe 3 within the conveying pipe 1.

[0057] During installation, the rectifier plate 2 and the clamping block 4 are installed in the rectifier tube 3 along the mounting groove 5. Then, the rectifier tube 3 is inserted into the delivery tube 1. The blocking plate 6 is aligned between the two sets of flanges 9. The delivery tube 1, the rectifier tube 3 and the rectifier plate 2 are fixed with fasteners. At this time, the blocking plate 6 is fixed at both ends of the rectifier tube 3 and the rectifier plate 2 is fixed inside the rectifier tube 3.

[0058] In one alternative implementation, such as Figure 5 As shown, the surface of the rectifier 2 has several arc-shaped grooves 7.

[0059] In this application, the arc-shaped groove 7 can disrupt the airflow boundary layer, reduce the drag force of the airflow on the material particles, reduce the air resistance when the material particles move, and further improve the conveying speed of the material particles. Through the synergistic effect of the rectifier plate 2 and the arc-shaped groove 7, the conveying efficiency of the material particles in the conveying pipe 1 is effectively improved, and the generated material particles can be conveyed to the destination more quickly and stably, reducing the conveying time and improving production efficiency.

[0060] In one optional embodiment, the outer diameter of the rectifier tube 3 is the same as the inner diameter of the conveying tube 1. This prevents the rectifier tube 3 from swaying within the conveying tube 1.

[0061] In one optional embodiment, the blocking plate 6 is an annular plate, and the inner diameter of the blocking plate 6 is the same as the inner diameter of the rectifier tube 3. This allows for axial positioning of the rectifier plate 2 and the rectifier tube 3. The outer diameter of the blocking plate 6 can be the same as the outer diameter of the flange 9, facilitating its fixation to the flange 9 and also providing positioning for the rectifier tube 3. During installation, the axis of the blocking plate 6 can coincide with the axis of the rectifier tube 3.

[0062] In one optional embodiment, the rectifier plates 2 are uniformly arranged circumferentially on the inner side of the rectifier tube 3. This allows for a more uniform distribution of material particles in the airflow.

[0063] This application effectively improves the conveying efficiency of polyolefin particles in the conveying pipe 1 through the synergistic effect of the rectifier plate 2 and the arc-shaped groove 7, which can more quickly and stably transport the polyolefin generated by the reactor 8 to the destination, reduce the conveying time, and improve production efficiency.

[0064] The detachable design of the rectifier 2 and the fixing method of the blockage plate 6 greatly improve the installation and maintenance convenience of the entire conveying pipeline. When the rectifier 2 is worn or needs cleaning, it can be quickly disassembled for processing, reducing equipment downtime, lowering maintenance costs, and ensuring the long-term stable operation of the conveying system.

[0065] In this application, the retaining block 4 of the rectifier 2 and the mounting groove 5 of the rectifier tube 3 can adopt a U-shaped mating structure. This structure allows the rectifier 2 to be easily inserted or removed along the mounting groove 5, realizing the detachable installation of the rectifier 2. During installation, the rectifier 2 is first installed in the mounting groove 5 of the rectifier tube 3 through the retaining block 4, then the rectifier tube 3 is inserted into the conveying pipe 1, and finally the blocking plate 6 is used to fix it between the two sets of flanges 9, confining the rectifier 2 inside the rectifier tube 3 to ensure that it will not loosen or fall off during the conveying process. During maintenance, only the fasteners need to be removed and the blocking plate 6 removed to easily remove the rectifier 2 for inspection, cleaning or replacement.

[0069] Reactor 8 is connected to the conveying pipeline;

[0070] An airflow device is connected to the conveying pipe and adapted to provide airflow to the conveying pipe in a direction away from the reactor 8. The airflow device can be an air compressor or air pump connected to the conveying pipe 1, and the provided gas flow is in the opposite direction to the reactor 8.

[0071] The conveying pipe 1 is fixedly connected to the output end of the reactor 8. The polyolefin generated by the reactor 8 is pneumatically conveyed through the conveying pipe 1. During the conveying process, the polyolefin particles flow with the airflow generated by the airflow device in the conveying pipe 1 to achieve the conveying purpose.
