Description

Technical Field

[0001] This invention relates to the fields of intelligent overhead conveying systems, laser measurement, and new energy technologies. Specifically, it relates to a conveying system and method for the production of chlorinated polyethylene granules based on intelligent monitoring. Background Technology

[0002] Currently, chlorinated polyethylene (CPE) is a widely used polymer material, playing a vital role in fields such as wires and cables, waterproof membranes, adhesive tapes and hoses, and impact modifiers for plastic and rubber products. The granule conveying process is crucial in its production. Traditional CPE granule conveying methods have several drawbacks. For example, while common pneumatic conveying can achieve long-distance granule transport, the granules are prone to friction against the inner wall of the pipe during transport, leading to severe wear and quality degradation. It also generates static electricity, which can cause granules to adhere to the pipe wall, affecting conveying efficiency and posing certain safety hazards. Furthermore, pneumatic conveying makes it difficult to monitor granules in real time during transport, failing to promptly detect quality problems such as particle size changes, impurity contamination, and agglomeration.

[0003] Furthermore, some traditional conveying equipment performs poorly in dust control, with inadequate sealing of conveying pipelines that easily leads to dust leaks. This not only pollutes the production environment and endangers the health of operators but may also cause safety accidents such as dust explosions. Moreover, existing conveying systems typically rely on traditional power grids for power, resulting in high energy consumption, which is inconsistent with current trends in energy conservation and environmental protection. In terms of intelligence, traditional conveying systems lack effective intelligent sensing and control systems, making it difficult to automatically adjust based on real-time data during the conveying process, thus failing to meet the demands of modern, high-efficiency production.

[0004] Specifically, the challenges include: achieving dust-free transport of chlorinated polyethylene (CPE) granules to reduce environmental and personnel hazards, while avoiding safety risks caused by dust and static electricity; real-time and accurate quality monitoring of CPE granules during transport, including particle size measurement, morphological observation, and impurity detection, to promptly identify and address quality issues; and improving production efficiency due to the low level of automation in the transport system, which cannot automatically deliver products to the appropriate workstations based on monitoring results. Furthermore, reducing energy consumption through clean energy supply and improving energy efficiency are crucial for green production. Finally, enhancing the intelligence of the transport system by using intelligent sensing systems to collect real-time data during transport and automating the process using a control system to improve both production efficiency and product quality.

[0005] In summary, at least one of the following technical problems exists:

[0006] How can we achieve dust-free transport of chlorinated polyethylene granules to reduce the harm of dust to the environment and personnel, while avoiding safety risks caused by dust and static electricity?

[0007] How to conduct real-time and accurate quality monitoring of chlorinated polyethylene particles during the conveying process, including particle size measurement, morphological observation, and impurity detection, so as to promptly detect and handle quality problems, and the low degree of automation of the conveying system makes it impossible to automatically transport products to the corresponding workstations based on monitoring results, thus making it difficult to improve production efficiency.

[0008] How to reduce the energy consumption of the transmission system, use clean energy for power supply, improve energy utilization efficiency, and achieve green production.

[0009] How to improve the intelligence level of the conveying system? By collecting various data in real time during the conveying process through an intelligent sensing system, and using the control system to automatically regulate the conveying process based on this data, we can improve production efficiency and product quality.

[0010] By setting up six conveying stations, including the first, second, third, fourth, fifth, and sixth stations, the fifth station is used for feeding and loading. After loading, the trolley is driven to transport the material along the conveying track. The material is monitored through a conveying pipe on one side. If all the material passes the inspection, it is discharged through the first conveying station. If the material does not meet the size requirements, it is discharged through the second conveying station. If the material contains impurities, it is discharged through the third station. If the material fails the dust inspection, it continues to the other side of the conveying pipe for dust removal. If all the material passes the inspection, it is discharged through the fourth station. If the material fails the inspection again, it is discharged through the sixth station. A diversion device is set up at the sixth station to classify and distribute the material according to the monitoring problems. If the material still fails the dust inspection, the cycle continues until the dust monitoring is qualified. This forms a multi-station intelligent scheduling system to achieve a closed loop of quality inspection and sorting. Summary of the Invention

[0077] In this embodiment, the intelligent sensing system 4 is integrated into the intelligent suspended conveying system 2 and is used to collect real-time data on the conveying of chlorinated polyethylene particles. The intelligent sensing system 4 includes: a dust monitoring sensor, which is installed in the conveying pipe 10; a position sensor, which is installed on the drive trolley 8; and an electrostatic induction sensor, which is installed in the roller 22. Specifically, it includes a dust monitoring sensor, a position sensor, and an electrostatic induction sensor. The dust monitoring sensor monitors the dust concentration in the conveying pipe 10, the position sensor determines the position of the drive trolley 8 and the rolling conveying unit 16, and the electrostatic induction sensor monitors the electrostatic condition of the particles in the roller 22, providing real-time data for the control system 5.

[0078] In this embodiment, a dust collection unit is connected to the conveying pipe 10. The dust collection unit includes: a dust collection pipe 29 connected to the conveying pipe 10; and a vacuum cleaner 11 connected to the dust collection pipe 29. The control system 5 monitors the dust in the conveying pipe 10 in real time using a dust monitoring sensor. When the dust concentration reaches a set threshold, the control system 5 controls the vacuum cleaner 11 to work, promptly removing the dust from the conveying pipe 10. Specifically, it consists of the dust collection pipe 29 and the vacuum cleaner 11. The dust collection pipe 29 is connected to the conveying pipe 10. When the control system 5 detects that the dust concentration exceeds the standard, it controls the vacuum cleaner 11 to work, using the dust collection pipe 29 to remove the dust from the conveying pipe 10, achieving dust-free conveying.

[0079] In this embodiment, a control system 5 is connected to the intelligent suspended conveyor system 2, the laser measurement and image acquisition system 3, the solar power supply system 1, the intelligent sensing system 4, and the dust collection unit. The control system 5 includes: a central processing unit 31, a solar power supply system control module 32, an intelligent suspended conveyor system control module 33, a laser measurement and image acquisition system control module 34, an intelligent sensing system control module 35, a dust collector control module 36, and a rotary motor control module 37. The central processing unit 31 is connected to each of these modules.

The central processing unit 31 receives data from each module and controls each module according to preset programs and algorithms to realize the intelligent operation of the entire conveying system.

[0080] In this embodiment, the intelligent suspended conveying system 2 uses a looped conveying track 9 and conveying pipe 10 as a nested structure. A vacuum cleaner 11 connects to the conveying pipe 10 for dust collection, enabling dust-free conveying. Simultaneously, a rolling conveying unit 16 dynamically removes dust from the chlorinated polyethylene particles. A composite laser measurement image acquisition system 3 and an image acquisition system perform dynamic monitoring of the rolling motion, and intelligent sensors provide real-time monitoring. Based on the monitoring results, the particles are conveyed to different workstations 6 as needed, or continue to be monitored or removed through circulation. The laser measurement image acquisition system 3 is installed on the inner wall of the conveying pipe 10 and combined with the intelligent sensing system 4 to achieve multi-dimensional real-time monitoring of the chlorinated polyethylene particles. The laser measuring devices 28 are arranged in a matrix, enabling multi-level composite monitoring of the particles during circumferential rotation and axial conveying, obtaining comprehensive and accurate particle information. Meanwhile, the intelligent sensing system 4 monitors environmental factors such as dust, position, and static electricity. The two work together to provide strong data support for precise control of the production process. By setting dust discharge holes 21 on the rolling conveyor unit 16 and equipping it with a dust collection unit, the conveying system can discharge dust in real time during the conveying process, and automatically activate the vacuum cleaner 11 to remove dust according to the dust concentration, thus realizing dynamic dust removal. Simultaneously, the laser measurement image acquisition system 3 and the intelligent sensing system 4 continuously monitor particles and the environment throughout the conveying process, ensuring product quality and the stability of the conveying environment. This collaborative processing method of dynamic dust removal and monitoring is advanced compared to similar conveying systems. Based on the automated processing of monitoring results, the control system 5 performs quality inspection on the chlorinated polyethylene particles according to the data collected by the laser measurement image acquisition system 3 and the intelligent sensing system 4, and automatically controls the intelligent suspended conveyor system 2 according to the inspection results to transport the particles to different workstations 6 or continue cyclical quality inspection or dust removal, realizing automated and intelligent decision-making in the production process, improving production efficiency and product quality stability. The conveying station 6 includes a first station 12, a second station 13, a third station 14, a fourth station 17, a fifth station 18, and a sixth station 19. The fifth station 18 is used for feeding and loading. After loading, the trolley 8 is driven to convey along the conveying track 9 and monitored through the conveying pipe 10 on one side. If all the materials are found to be qualified, they are unloaded through the first conveying station 12. If the materials are found to be unqualified in size, they are unloaded through the second conveying station 13. If there are impurities, they are unloaded through the third station 14. If the materials are found to be unqualified in dust, they continue to enter the other conveying pipe 10 for dust removal. When all the materials are found to be qualified, they are unloaded through the fourth station 17. If there are any unqualified materials after re-monitoring, they are unloaded through the sixth station 19. A diversion device is set at the sixth station 19 to divert and classify materials according to the monitoring problems. If the dust is still unqualified, the cycle continues until the dust monitoring is qualified. This forms a multi-station intelligent scheduling system to realize a closed loop of quality inspection and sorting. Each roller 22 is equipped with a dust monitoring sensor.Energy cycle: Solar panel 7 → Battery pack 15 → Power supply to various subsystems; Material conveying: Drive trolley 8 circulates along conveying track 9 → Roller 22 rotates and conveys → Multi-station switching; Quality monitoring: Laser beam 27 penetrates transparent monitoring window 20 → 3D point cloud modeling → Particle size analysis, while image acquisition unit, for example, acquires real-time dynamic images of particulate matter within transparent monitoring window 20 via camera or scanner, and the control system 5 performs 3D point cloud modeling on the laser acquisition and processes and compares the images acquired by the image acquisition unit. Dust removal control: Dust discharge hole 21 roller dust discharge → suction pipe 29 → vacuum cleaner 11 negative pressure dust removal. Intelligent scheduling: Central processor 31 receives data from multiple sensors → controls the rotation speed of rotary motor 30 → switches branch tracks to convey different workstations 6.

[0081] In this embodiment, the laser measurement image acquisition system 3, the intelligent sensing system 4, and the control system 5 are combined to achieve comprehensive, real-time monitoring and intelligent control of the chlorinated polyethylene granule conveying process. By collecting and analyzing data such as granule quality and conveying status in real time, various parameters during the conveying process are automatically adjusted to improve production efficiency and product quality. The connection between the conveying pipe 10 and the dust collection unit, along with the dust discharge port 21 of the rolling conveyor unit 16, effectively solves the dust pollution problem and improves the safety and cleanliness of the production environment. The introduction of the solar power supply system 1 utilizes solar energy to provide power to the conveying system, achieving energy conservation and environmental protection, reducing production costs, and conforming to the concept of sustainable development. The unique structural design of the rolling conveyor unit 16, including the hexahedral structure of the roller 22, the alternating dust discharge ports 21 and transparent monitoring windows 20, the automatic opening and closing doors of the feed and discharge ports 25, and the electrostatic conductive plates 24 on the drive shaft 23, enables the granules to achieve rolling dust removal during conveying, facilitates monitoring, and prevents static electricity accumulation, thus improving the stability and reliability of the conveying process.

[0082] Another embodiment of the present invention provides a method for using a conveying system for the production of chlorinated polyethylene granules based on intelligent monitoring, comprising:

[0083] Step 1: Control the solar power system 1 to supply power through the control system 5;

[0084] Step 2: The chlorinated polyethylene granules are loaded into the rolling conveying unit 16 of the intelligent suspension system 2 through the conveying station 6, and the rolling conveying unit 16 is driven by the drive trolley 8 to transport the monitoring and dust removal chlorinated polyethylene granules along the conveying track 9 in the conveying pipe 10.

[0085] Step 3: The conveying process is simultaneously monitored in real time by the intelligent sensing system 4 and the laser measurement image acquisition system 3;

[0086] Step 4: When the intelligent sensing system 4 detects that the dust in the conveying pipe 10 has reached the threshold, the vacuum cleaner 11 removes the dust in time.

[0087] Step 5: Based on the monitoring results, transport the chlorinated polyethylene granules to different workstations 6.

[0088] Working principle:

[0089] Solar panels 7 are arranged in an array at the top of the factory building to convert solar energy into electrical energy, which is stored in battery banks 15 connected to the solar panels 7. The solar power supply system control module 32 in the control system 5 controls the battery banks 15 to supply power to various electrical devices according to the power demand of the transmission system, ensuring the stable operation of the system.

[0090] The intelligent suspended conveying system 2 uses a circular conveying track 9, which includes conveying stations 6 and branch tracks. A drive trolley 8 is mounted on the drive track, and the rolling conveying unit 16 is detachably connected to the drive trolley 8 via a bracket 26. Under the control of the intelligent suspended conveying system control module 33 in the control system 5, the drive trolley 8 drives the rolling conveying unit 16 along the conveying track 9 within the conveying pipe 10. Chlorinated polyethylene granules are loaded from the conveying station 6 into the rollers 22 of the rolling conveying unit 16. The rollers 22 rotate via a drive shaft 23 and a rotary motor 30. During rotation, the granules continuously tumble, aiding in uniform dust removal and monitoring. Laser measuring devices 28 in the laser measurement image acquisition system 3 are arranged in a matrix along the axial direction of the conveying pipe 10, opposite the rollers 22, on the inner wall of the conveying pipe 10, and are symmetrically positioned. The laser measuring devices 28 employ lidar, emitting laser beams 27 to perform multi-level composite monitoring of the chlorinated polyethylene granules in the rollers 22 of the rolling conveying unit 16 during circumferential rotation and axial conveying. During the monitoring process, the particle information acquired by the laser measuring device 28 is transmitted to the laser measurement image acquisition system control module 34 in the control system 5 for analysis and processing.

[0091] Dust monitoring sensors in the intelligent sensing system 4 are installed in the conveying pipe 10 to monitor the dust concentration in real time. Position sensors are installed on the drive trolley 8 to determine the position of the drive trolley 8 and the rolling conveyor unit 16. Electrostatic induction sensors are installed in the roller 22 to monitor the electrostatic charge of the particles inside. The data collected by these sensors are transmitted to the intelligent sensing system control module 35 in the control system 5. When the dust monitoring sensors detect that the dust concentration in the conveying pipe 10 reaches a set threshold, the vacuum cleaner control module 36 in the control system 5 controls the vacuum cleaner unit to operate. The vacuum cleaner pipe 29 is connected to the conveying pipe 10, and the vacuum cleaner 11 removes the dust from the pipe. Simultaneously, based on the data from each sensor and the monitoring results from the laser measurement image acquisition system 3, the control system 5 adjusts the running speed and direction of the drive trolley 8 through the intelligent suspended conveyor system control module 33, conveying the chlorinated polyethylene particles to different workstations 6 according to the monitoring results.

[0092] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0093] By connecting the conveying pipe 10 to the dust collection unit via the conveying track 9, and designing the dust discharge hole 21 of the rolling conveying unit 16, and by using the rolling dust screen of the roller 22, dust generated during the conveying process can be effectively collected, achieving dust-free conveying, reducing the harm of dust to the environment and personnel, and reducing safety hazards.

[0094] The laser measurement image acquisition system 3 can perform multi-level composite monitoring of chlorinated polyethylene particles in the rolling conveyor unit 16 during circumferential rotation and axial conveying through the transparent monitoring window 20. It can acquire information such as particle size, morphology, and particle motion status in real time, promptly detect quality problems, ensure product quality, and perform three-dimensional online monitoring of moving particles.

[0095] The solar power system 1 uses solar panels 7 to collect solar energy and convert it into electrical energy, which is stored in the battery pack 15 to power the entire transmission system. This reduces dependence on the traditional power grid, lowers energy consumption, and achieves energy conservation and environmental protection.

[0096] The intelligent sensing system 4, integrated into the intelligent suspended conveyor system 2, can collect various data on the conveying of chlorinated polyethylene particles in real time, such as dust concentration, particle conveying position, and static electricity. Based on this real-time data, the control system 5 automatically controls the solar power supply system 1, the intelligent suspended conveyor system 2, the laser measurement and image acquisition system 3, the dust collection unit, and the rotary motor 30 through various control modules, thereby improving production efficiency and product quality while reducing manual intervention costs.

[0097] By setting up conveying stations 6, including station 12, station 13, station 14, station 17, station 18, and station 19, station 18 is used for feeding and loading. After loading, the trolley 8 is driven to transport the material along the conveying track 9 and monitors it through the conveying pipe 10 on one side. If all the material passes the monitoring, it is discharged through station 12. If the size does not meet the monitoring, it is discharged through station 13. If there are impurities, it is discharged through station 14. If the dust does not meet the monitoring, it continues to enter the other conveying pipe 10 for dust removal. When all the material passes the monitoring, it is discharged through station 17. If there are any defects after re-monitoring, it is discharged through station 19. A diversion device is set at station 19 to divert and classify the material according to the monitoring problem. If the dust still does not meet the monitoring, the cycle continues until the dust monitoring is qualified. This forms a multi-station intelligent scheduling system to realize a closed loop of quality inspection and sorting.

[0098] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the invention should be included within the scope of protection of the invention.
