Description

Technical Field

[0001] This invention relates to the field of dismantling and recycling of waste electrical components, and in particular to an automated dismantling production line and an automated dismantling method. Background Technology

[0002] With the increasing scale of power grid equipment upgrades and decommissioning, rod-shaped power devices such as composite insulators and surge arresters need to be dismantled and recycled after decommissioning. These devices typically include metal terminals, outer sheds, and internal main components. The internal main component of composite insulators is usually a rod core, while the internal main component of surge arresters is usually a cylinder, which may also include components such as zinc oxide varistors and insulating cylinders.

[0003] Current processing methods mostly employ manual dismantling or simple crushing. Manual dismantling suffers from low efficiency, high labor intensity, and high labor costs; simple crushing easily results in the mixing of materials such as metal, rubber, glass fiber, zinc oxide valve plates, and insulating cylinders, making subsequent sorting difficult and hindering the improvement of resource recovery purity.

[0004] In addition, some existing dismantling equipment can only complete a single process and lacks the ability to continuously separate and classify the umbrella skirt fragments, metal ends, rod cores, cylinders, and materials inside the cylinder, resulting in insufficient continuity of dismantling operations and inadequate classification of recycled materials. Summary of the Invention

[0005] The purpose of this invention is to provide an automated dismantling production line and an automated dismantling method to solve the problems of low dismantling efficiency, insufficient material separation, mixed recycled materials, and insufficient continuous processing capacity in the existing process of dismantling scrap rod-shaped power devices.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An automated dismantling production line for dismantling and recycling scrapped rod-shaped electrical devices includes: a dismantling device for separating the skirts and cutting the metal ends of the scrapped rod-shaped electrical devices, and separating the resulting skirt fragments from a mixture including the metal ends and an internal main body component; a mixture conveyor line connected to the dismantling device for receiving and conveying the metal ends and the internal main body component; and a main body component conveyor line spaced apart from the mixture conveyor line along the conveying direction to form a separation gap between the mixture conveyor line and the main body component conveyor line, the separation gap being used to allow the metal ends to be separated from the internal main body component component. The end falls, causing the internal main body component to enter the main body component conveyor line; a stepped material sorting machine, connected to the main body component conveyor line, is used to distinguish between rod-type main body components and cylindrical main body components in the internal main body components, and outputs the rod-type main body components and the cylindrical main body components respectively; a cylindrical separation press, corresponding to the cylindrical main body component output side of the stepped material sorting machine, is used to separate the cylindrical main body components to separate the zinc oxide valve plate and the insulating cylinder; a sorting and collection mechanism is used to collect the umbrella skirt fragments, the metal end, the rod-type main body components, the zinc oxide valve plate and the insulating cylinder respectively.

[0007] Furthermore, the dismantling device includes a skirt cutting mechanism, a metal end cutting mechanism, and a diversion baffle. The skirt cutting mechanism is used to cut the skirt of the scrapped rod-shaped power device to form the skirt fragments. The metal end cutting mechanism is used to cut the metal end of the scrapped rod-shaped power device to separate the metal end from the internal main body. The diversion baffle is disposed on the discharge side of the dismantling device to guide the skirt fragments to the skirt fragment output path and to guide the metal end and the internal main body to the mixed material conveying line.

[0008] Furthermore, the umbrella skirt cutting mechanism includes an ultrasonic rubber cutting blade, the blade head of which is positioned facing the umbrella skirt around the outer periphery of the scrapped rod-shaped power device, for cutting the umbrella skirt and forming umbrella skirt fragments.

[0009] Furthermore, the cutting position of the metal end cutting mechanism corresponds to the end of the scrapped rod-shaped power device, so that the metal end is separated from the internal main body into material that can be conveyed by the mixed material conveying line.

[0010] Furthermore, the width of the separation gap in the conveying direction is less than the length of the inner main body and greater than the length of the metal end in the conveying direction, so that the metal end falls through the separation gap and the inner main body crosses the separation gap to enter the main body conveying line.

[0011] Furthermore, the sorting and collection mechanism includes a metal end collection branch, which includes a metal end inclined conveyor line and a metal end collection ton bag. The metal end inclined conveyor line is correspondingly located below or downstream of the separation gap, and the metal end collection ton bag is correspondingly located at the discharge end of the metal end inclined conveyor line.

[0012] Furthermore, the stepped feeder has a bar core type main component output path and a cylinder type main component output path. The bar core type main component output path is set to correspond to the bar core type main component collection ton bag, and the cylinder type main component output path is set to correspond to the pre-processing position of the cylinder separation press.

[0013] Furthermore, the cylinder separation press includes a pressure-bearing station for placing the cylinder-like main body and a pressure head for applying pressure to the cylinder-like main body. The pressure-bearing station and the pressure head are arranged opposite to each other to separate the zinc oxide valve plate in the cylinder-like main body from the insulating cylinder.

[0014] Furthermore, the sorting and collection mechanism includes a skirt fragment collection branch, which includes a skirt fragment conveying line, a skirt fragment ramping conveying line, and a skirt fragment collection ton bag. The skirt fragment conveying line is connected to the skirt fragment output side of the dismantling device, the skirt fragment ramping conveying line is connected to the skirt fragment conveying line, and the skirt fragment collection ton bag is correspondingly located at the discharge end of the skirt fragment ramping conveying line.

[0015] This invention also provides an automatic dismantling method, employing the aforementioned automatic dismantling production line for dismantling and recycling. The automatic dismantling method includes the following steps: feeding a scrapped rod-shaped electrical device into a dismantling device; the dismantling device performs umbrella-skirt cutting and metal end cutting on the scrapped rod-shaped electrical device to form umbrella-skirt fragments, metal ends, and internal main components; the dismantling device separates the umbrella-skirt fragments from a mixture including the metal ends and the internal main components, wherein the umbrella-skirt fragments enter an umbrella-skirt fragment output path, and the metal ends and internal main components enter a mixture conveyor line; the mixture conveyor line transports the metal ends and internal main components, and the metal ends are separated... The internal main component falls from the gap, allowing it to cross the separation gap and enter the main component conveyor line. The conveyor line transports the internal main component to a stepped feeder, which separates the rod-type and cylindrical main components, outputting them separately. The rod-type main components are sent to their corresponding collection positions, while the cylindrical main components are sent to a cylindrical separation press. The cylindrical separation press separates the cylindrical main components to separate the zinc oxide valve plate and the insulating cylinder. The umbrella skirt fragments, the metal end, the rod-type main component, the zinc oxide valve plate, and the insulating cylinder are collected separately.

[0016] Analysis shows that the present invention discloses an automatic dismantling production line and an automatic dismantling method. The present invention uses a dismantling device to separate the skirts and cut the metal ends of scrapped rod-shaped power devices, and uses a diversion output to separate the skirt fragments from the mixture of materials including the metal ends and the internal main body, which helps to reduce the mixing of different materials in the initial dismantling stage.

[0023] This embodiment provides an automated dismantling production line for dismantling and recycling scrapped rod-shaped power devices. The scrapped rod-shaped power devices can be scrapped composite insulators, scrapped surge arresters, or other rod-shaped power devices with sheds, metal terminals, and internal main components. Composite insulators typically include metal terminals, silicone rubber sheds, and a fiberglass rod core; surge arresters typically include metal terminals, sheds, and a cylindrical assembly, wherein the cylindrical assembly includes an insulating cylinder and a zinc oxide valve plate disposed within the insulating cylinder. For ease of consistent description, in this embodiment, the fiberglass rod core of the composite insulator is referred to as the rod core-type main component, the cylindrical assembly requiring further separation after surge arrester dismantling is referred to as the cylinder-type main component, and both the rod core-type and cylinder-type main components are collectively referred to as the internal main components.

[0024] The automated dismantling production line of this embodiment includes a dismantling device 1, a mixed material conveying line 2, a main component conveying line 5, a stepped material sorting machine 6, a cylinder separation press 9, and a sorting and collection mechanism. This system can be understood as consisting of a dismantling section, a conveying and diverting section, a stepped material sorting section, and a cylinder-type main component separation and processing section. Specifically, the dismantling section is used to complete the skirt separation and metal end cutting; the conveying and diverting section is used to guide different materials into corresponding conveying paths or collection locations; the stepped material sorting section is used to distinguish between rod-type and cylinder-type main components; and the cylinder-type main component separation and processing section is used to separate the zinc oxide valve plates and insulating cylinders within the cylinder-type main components.

[0025] The dismantling device 1 is used to separate the skirts and cut the metal ends of scrapped rod-shaped electrical components, and to separate the resulting skirt fragments from the mixture including the metal ends and internal main body components for output. The dismantling device 1 can be equipped with a detection structure to detect the length of the scrapped rod-shaped electrical components, enabling the system to determine the cutting range or conveying cycle based on the length of the component to be dismantled. The dismantling device 1 can also be equipped with a positioning support structure to support the component to be dismantled, so as to maintain the stability of the component's position during the cutting process. The aforementioned detection structure and positioning support structure are optional implementations of the dismantling device 1, used to improve the stability of the dismantling process and its adaptability to products of different specifications.

[0026] The dismantling device 1 includes a skirt cutting mechanism, a metal end cutting mechanism, and a diversion baffle. The skirt cutting mechanism cuts the skirt of the scrapped rod-shaped power device to form skirt fragments. The metal end cutting mechanism cuts the metal end of the scrapped rod-shaped power device to separate the metal end from the internal main body. The diversion baffle is located on the discharge side of the dismantling device 1 to guide the skirt fragments to the skirt fragment output path and to guide the metal end and the internal main body to the mixed material conveying line 2. With the above structure, the dismantling device 1 can not only complete the cutting operation but also immediately complete the initial diversion of materials after dismantling.

[0027] In one embodiment, the skirt cutting mechanism includes an ultrasonic rubber cutter. The blade of the ultrasonic rubber cutter is positioned towards the skirt surrounding the scrapped rod-shaped electrical device, and is used to cut the skirt and form skirt fragments. Since the skirts of scrapped composite insulators and surge arresters are typically made of silicone rubber, using an ultrasonic rubber cutter improves skirt cutting efficiency and reduces dust, noise, and irregular damage caused by traditional crushing or mechanical tearing methods. This cutting method also reduces the risk of damage to internal rod-shaped cores or cylindrical main components.

[0028] The metal end cutting mechanism cuts at the end of the scrapped rod-shaped power device to separate the metal end from the internal main body, making it a material that can be conveyed by the mixed material conveying line 2. For scrapped composite insulators, the metal end is separated from the rod-shaped main body after cutting; for scrapped surge arresters, the metal end is separated from the cylindrical main body after cutting. The cut metal end and the internal main body enter the mixed material conveying line 2 together, where a subsequent separation notch completes the further separation of the metal end from the internal main body.

[0029] The mixed material conveyor line 2 connects to the dismantling device 1 to receive and transport the metal end and the internal main body. Since the metal end and the internal main body differ in length, a complex sorting structure is not immediately required at the discharge end of the dismantling device 1. Instead, they can be transported together by the mixed material conveyor line 2 and then separated in subsequent transport paths. This arrangement simplifies the discharge side structure of the dismantling device 1, making the entire production line layout more compact.

[0030] The main component conveyor line 5 and the mixed material conveyor line 2 are spaced apart along the conveying direction to form a separation gap between them. This separation gap allows the metal end to fall and the internal main component to enter the main component conveyor line 5. Specifically, the width of the separation gap in the conveying direction is less than the length of the internal main component but greater than the length of the metal end in the conveying direction. When the metal end reaches the separation gap, its shorter length prevents it from crossing the gap, causing it to fall. Conversely, when the internal main component reaches the separation gap, its longer length allows it to cross the gap and enter the main component conveyor line 5. Thus, the system utilizes the length difference between the metal end and the internal main component to separate materials, eliminating the need for a complex active sorting mechanism at this location.

[0031] The sorting and collection mechanism includes a metal end collection branch. This branch comprises a metal end inclined conveyor line 3 and a metal end collection ton bag 4. The metal end inclined conveyor line 3 is positioned below or downstream of the separation gap to receive metal ends falling through it and transport them to the metal end collection ton bag 4. The metal end collection ton bag 4 is positioned at the discharge end of the metal end inclined conveyor line 3 for centralized collection of metal ends. Through this structure, metal ends can be screened out of the mixture and collected for centralized recovery.

[0032] The main component conveyor line 5 receives the internal main components after they have crossed the separation gap and conveys them to the stepped sorting machine 6. The internal main components can include rod-type main components and cylindrical main components. Rod-type main components are typically fiberglass rods after dismantling composite insulators, while cylindrical main components are typically insulating cylinders and their internal components after dismantling surge arresters. The main component conveyor line 5 continues to convey the internal main components, after metal-end separation, to the stepped sorting machine 6 for further sorting.

[0033] The stepped feeder 6 connects to the main component conveyor line 5 and is used to distinguish between rod-type and cylindrical main components within the internal main components, outputting them separately. The stepped feeder 6 has separate output paths for rod-type and cylindrical main components. The output path for rod-type main components corresponds to the rod-type main component collection ton bag 7, while the output path for cylindrical main components corresponds to the pre-processing position of the cylindrical separation press 9. After sorting by the stepped feeder 6, rod-type main components can directly enter the collection process, while cylindrical main components enter the subsequent separation process.

[0034] The cylinder separation press 9 is positioned corresponding to the output side of the cylindrical main body of the stepped feeder 6, and is used to separate the cylindrical main body to separate the zinc oxide valve plates and insulating cylinders. The cylinder separation press 9 includes a pressure-bearing station for placing the cylindrical main body and a pressure head for applying pressure to the cylindrical main body; the pressure-bearing station and the pressure head are positioned opposite each other. After the cylindrical main body is sent to the pre-processing position of the cylinder separation press 9, it can be placed in the pressure-bearing station by an operator or auxiliary device. Pressure is applied to the cylindrical main body through the pressure head, causing the zinc oxide valve plates in the cylindrical main body to separate from the insulating cylinders. The separated zinc oxide valve plates enter the zinc oxide valve plate collection ton bag 8, and the insulating cylinders enter the insulating cylinder collection ton bag 10.

[0035] The sorting and collection mechanism also includes a skirt fragment collection branch. This branch includes a skirt fragment conveyor line 11, a skirt fragment inclined conveyor line 12, and a skirt fragment collection ton bag 13. The skirt fragment conveyor line 11 connects to the skirt fragment output side of the dismantling device 1 to receive the skirt fragments output from the dismantling device 1. The skirt fragment inclined conveyor line 12 connects to the skirt fragment conveyor line 11 to continue conveying the skirt fragments. The skirt fragment collection ton bag 13 is correspondingly located at the discharge end of the skirt fragment inclined conveyor line 12 for centralized collection of the skirt fragments.

[0036] This implementation method does not rely solely on manual dismantling or overall crushing, but rather completes the following sequentially on an assembly line: skirt separation, metal end cutting, skirt fragment diversion, metal end screening, internal main component sorting, and separation and collection of cylindrical main components. Specifically, the dismantling device 1 first separates the skirt fragments from the mixture including metal ends and internal main components; the separation gap between the mixed material conveyor line 2 and the main component conveyor line 5 further separates the metal ends from the internal main components; the stepped material sorting machine 6 further separates the rod-shaped main components and cylindrical main components within the internal main components; and the cylindrical separation press 9 continues to separate the zinc oxide valve plates and insulating cylinders within the cylindrical main components. This processing path corresponds to the structural composition of scrapped rod-shaped power devices, reducing material mixing and improving the convenience of classification and recycling.

[0037] In a specific application scenario, the object to be processed can be a 35kV FXBW4-35 type composite insulator. This type of composite insulator can have a length of approximately 500mm and a fiber rod diameter of approximately 30mm. During operation, the operator feeds the composite insulator into the dismantling device 1, which cuts its skirts to form skirt fragments and simultaneously cuts the end metal ends, separating the metal ends from the core components. The skirt fragments enter the skirt fragment collection ton 13 via the skirt fragment collection branch, while the metal ends fall through the separation notch and enter the metal end collection branch. The core components cross the separation notch and enter the core component conveyor line 5, and are then output to the core component collection ton 7 via the stepped feeder 6. In this scenario, the dismantling process can reduce manual cutting operations and allows for the separate collection of skirt fragments, metal ends, and core components.

[0038] In another specific application scenario, the object to be processed can be a YH5WZ-51 / 134 type surge arrester. This type of surge arrester can have a length of approximately 620mm and a cylinder diameter of approximately 135mm. During operation, the operator feeds the surge arrester into the dismantling device 1, which cuts its skirt to form skirt fragments and simultaneously cuts the metal end, separating the metal end from the main cylinder component. The skirt fragments enter the skirt fragment collection branch, while the metal end falls at the separation gap and is collected by the metal end collection ton 4. The main cylinder component crosses the separation gap and enters the stepped feeder 6 via the main component conveyor line 5, and is then output by the stepped feeder 6 to the pre-processing position of the cylinder separation press 9. Subsequently, the cylinder separation press 9 applies pressure to the main cylinder component, causing the zinc oxide valve plate to separate from the insulating cylinder, and they enter the zinc oxide valve plate collection ton 8 and the insulating cylinder collection ton 10 respectively.

[0039] In practical implementation, this system can be configured with two operators. One operator is responsible for feeding and observing the operating status at the disassembly device 1 end, confirming that the umbrella skirt fragments, metal ends, rod-type main components, or cylindrical main components enter the corresponding conveying path; the other operator is responsible for the secondary processing at the cylindrical separation press 9, placing the cylindrical main components in the cylindrical separation press 9 for pressing, and placing the separated zinc oxide valve plates and insulating cylinders into the corresponding collection containers. For the above-mentioned types of composite insulators and surge arresters, in one embodiment, a single production line can process approximately 60 composite insulators / hour and approximately 50 surge arresters / hour; the overall processing capacity of the system can be adjusted within a certain range according to the specifications of the components to be disassembled, the conveying cycle time, and the manual assistance cycle time. In one embodiment, the processing capacity can reach approximately 0.4 tons / hour to 0.7 tons / hour.

[0040] The automated dismantling method of this embodiment can be implemented using the aforementioned automated dismantling production line. The overall usage process is as follows: First, the scrapped rod-shaped power device is fed into the dismantling device 1. The skirt cutting mechanism in the dismantling device 1 cuts the skirt around the scrapped rod-shaped power device to form skirt fragments; the metal end cutting mechanism cuts the metal end of the scrapped rod-shaped power device, separating the metal end from the internal main body. Subsequently, the dismantling device 1 separates the skirt fragments from the mixture including the metal end and the internal main body through a diversion baffle. The skirt fragments enter the skirt fragment output path and are conveyed to the skirt fragment collection ton bag 13 by the skirt fragment conveying line 11 and the skirt fragment ramping conveying line 12; the metal end and the internal main body enter the mixture conveying line 2. Subsequently, the mixture conveying line 2 conveys the metal end and the internal main body to the separation gap. Due to its shorter length in the conveying direction, the metal end falls through the separation gap and enters the metal end inclined conveyor line 3, and is then conveyed by the metal end inclined conveyor line 3 to the metal end collection ton bag 4. The internal main body component, due to its longer length in the conveying direction, crosses the separation gap and enters the main body component conveyor line 5. Subsequently, the main body component conveyor line 5 conveys the internal main body component to the stepped feeder 6. The stepped feeder 6 separates the core-type main body components and the cylindrical-type main body components within the internal main body component and outputs them separately. The core-type main body component enters the core-type main body component collection ton bag 7, while the cylindrical-type main body component is sent to the pre-processing position of the cylindrical-type separation press 9. Subsequently, the cylindrical-type main body component is typically a cylindrical assembly of a scrapped surge arrester after the skirts and metal ends have been removed. The cylindrical assembly includes an insulating cylinder and a zinc oxide valve plate disposed within the insulating cylinder. The separated zinc oxide valve plate enters the zinc oxide valve plate collection ton bag 8, and the separated insulating cylinder enters the insulating cylinder collection ton bag 10. Finally, the system completes the classification and collection of umbrella skirt fragments, metal ends, rod-shaped main components, zinc oxide valve plates, and insulating cylinders, thereby realizing the continuous dismantling and classified recycling of scrapped rod-shaped power devices.

[0041] Compared to existing technologies, this invention achieves the following beneficial effects: First, it separates the skirts and cuts the metal ends of scrapped rod-shaped power devices using a dismantling device. Second, it separates the skirt fragments from the mixture including the metal ends and internal main components through a diversion output, reducing mixing of different materials during the initial dismantling stage. Third, it utilizes the separation gap between the mixed material conveying line and the main component conveying line, taking advantage of the difference in length between the metal ends and the internal main components in the conveying direction, causing the metal ends to fall and separate while allowing the internal main components to enter the main component conveying line, thus achieving a simple and continuous metal end separation. Fourth, it uses a stepped material handling machine to distinguish between rod-shaped and cylindrical main components and outputs them separately, facilitating the classification and processing of composite insulator and surge arrester materials. Fifth, it uses a cylindrical separation press to separate cylindrical main components, separating the zinc oxide valve plates and insulating cylinders, which helps improve the recycling purity of cylindrical materials. This invention uses a sorting and collection mechanism to collect umbrella skirt fragments, metal ends, rod core components, zinc oxide valve plates, and insulating cylinders separately, which helps to reduce the difficulty of subsequent sorting and improves the continuity and sorting of dismantling and recycling.

[0042] 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 present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
