Description

Technical Field

[0001] This invention relates to the field of power material recycling technology, specifically to a porcelain insulator recycling device and its working method. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] Insulators are commonly used components in power systems. As power systems operate, a large number of insulators that no longer meet usage requirements are removed. Among them, the polymer materials, glass fibers, and metal components in composite insulators can be recycled and reused. Similarly, the metal materials and scrap porcelain shards in porcelain insulators can also be recycled and reused. During recycling, porcelain insulators are generally broken by hammering to separate the metal core rod from the porcelain skirt. This recycling method generates a large number of porcelain shards, whose sharp edges can easily injure workers. Furthermore, the flying porcelain shards during hammering can also cause personal injury. Summary of the Invention

[0004] To address the technical problems mentioned above, this invention provides a porcelain insulator recycling device and its operating method. Taking into account the structural characteristics of porcelain insulators, the device uses a feeding unit to feed the porcelain insulators to be recycled one by one into a dismantling workbench and place them in "C"-shaped supports. The dismantling machine uses a pneumatic hammer to strike one end of the insulator's core rod, causing the porcelain skirt portion of the insulator to break under the shearing action of the C-shaped supports. The metal core rod then falls from the hollow portion of the C-shaped supports into the discharge rail, achieving the separation of the metal core rod and the porcelain skirt fragments. This system can operate automatically without manual intervention, thereby reducing the potential for personal injury from porcelain fragments.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A first aspect of the present invention provides a ceramic insulator recycling device, comprising:

[0007] The feeding unit is used to accept the insulators to be recycled and transport them to the dismantling workbench;

[0008] The dismantling unit includes a dismantling machine and a dismantling workbench. The dismantling workbench is equipped with a C-shaped support. The metal end of the insulator is hammered by the air hammer of the dismantling machine. Under the shearing action of the C-shaped support, the porcelain skirt is broken and separated from the metal core rod. The broken porcelain pieces are recycled and stored by the discharge unit, and the separated metal core rod falls into the space below the hollow part of the C-shaped support for collection.

[0009] Furthermore, the feeding unit has a conveying plane that drives the insulator to move. A fixed groove is provided at a set position on the conveying plane. One side of the fixed groove faces the disassembly workbench, and the other side is provided with a transverse push plate driven by a transverse cylinder. The movement direction of the transverse push plate is perpendicular to the transport direction of the insulator.

[0010] Furthermore, the conveying plane has a strip groove for accommodating the metal head at one end of the insulator, and the metal core rod of the insulator in the conveying plane is arranged in a vertical direction.

[0011] Furthermore, the setting position of the strip groove has a fixing groove, which is used to accommodate the lower half of the insulator. The fixing groove is connected to the disassembly unit through a feeding slide rail.

[0012] Furthermore, the transverse push plate is arc-shaped, and the curvature of the arc matches the diameter of the insulator.

[0013] Furthermore, the disassembly unit includes a disassembly machine and a disassembly workbench. The disassembly workbench is equipped with a feeding slide rail, one end of which is connected to a fixed groove on the conveying plane, and the other end is the disassembly position.

[0014] Furthermore, the dismantling machine has an air hammer located above the dismantling position. A C-shaped support is provided at the dismantling position, with the opening of the C-shaped support facing the feeding slide rail. A discharge slide rail is provided in the space below the hollow part of the C-shaped support.

[0015] Furthermore, the air hammer strikes the insulator's metal core rod in the dismantling position vertically. Under the impact of the air hammer, the C-type support generates shear force on the insulator's porcelain skirts and breaks them. The broken porcelain pieces fall into the discharge unit below the dismantling position.

[0016] Furthermore, the starting end of the discharge unit is located in the space below the C-shaped support, and the end is equipped with a recycling box.

[0017] Furthermore, an outer protective cover is installed on the outside of the disassembly workbench.

[0018] A second aspect of the present invention provides a method for operating the above-described apparatus, comprising the following steps:

[0019] The insulators are manually transferred to the loading unit, and then moved to the dismantling area while the insulators are kept vertical.

[0020] When the insulator reaches the fixed slot of the feeding unit, the transverse cylinder is activated to push the insulator along the feeding slide rail into the C-type support of the dismantling unit.

[0021] When the dismantling machine is started, it hammers the core rod head at the top of the insulator. The resulting shed fragments fall to the discharge unit below the C-type support for recycling, and the separated core rod falls to the discharge slide rail below the hollow part of the C-type support for recycling.

[0022] The discharge unit transports the umbrella skirt fragments to the recycling bin for temporary storage. Depending on the dismantling process requirements, the recycling bin is then sent to the sorting area or stored in the warehouse.

[0023] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects:

[0024] 1. Taking into account the structural characteristics of porcelain insulators, the feeding unit feeds the porcelain insulators to be recycled one by one into the dismantling workbench and places them in the "C"-shaped supports. The pneumatic hammer of the dismantling machine strikes one end of the insulator's core rod, causing the porcelain skirt part of the insulator to break under the shearing action of the C-shaped support. The metal core rod then falls from the hollow part of the C-shaped support into the discharge slide rail, realizing the separation of the metal core rod and the porcelain skirt fragments. It can operate in an automated manner without human intervention, thereby reducing the possibility of personal injury from porcelain fragments.

[0025] 2. By using a feeding unit with a certain transport distance, the manual feeding area and the automatic dismantling area are separated. When dismantling is required, the insulators are pushed into the dismantling position one by one using a cylinder, ensuring that the flying porcelain pieces do not affect manual operation during the dismantling operation and reducing possible personal injury.

[0037] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0038] It should be noted that the following detailed descriptions are exemplary and intended to provide further illustration of the invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0039] Porcelain insulators and composite insulators are both commonly used components in high-voltage equipment, and they have different advantages and disadvantages, for example:

[0040] Porcelain insulators: Typically made of electrical ceramics, they possess stable chemical properties, high resistivity, and high dielectric strength. Their structure generally consists of two hemispherical bushings and end metals. The surface is often covered with porcelain enamel to increase surface smoothness, waterproofing, and mechanical strength. However, porcelain insulators are relatively heavy, inconvenient to install, and may explode and shatter into porcelain pieces under certain extreme conditions.

[0041] Composite insulators mainly consist of one or more insulator cores, bushings, and end metal sections. The cores are typically made of epoxy fiberglass, while the sheaths and skirts are often made of synthetic materials such as silicone rubber. The connection points at both ends are usually metal. This structure gives composite insulators both excellent electrical performance and a certain degree of mechanical strength. Unlike porcelain insulators, composite insulators are generally manufactured in strings to compensate for their relatively weaker radial stress resistance. Furthermore, due to the extensive use of rubber-based materials, composite insulators are prone to aging, potentially leading to thermal degradation and blistering.

[0042] The two types of insulators differ in materials, structure, and performance, and therefore the recycling processes used are also different. As introduced in the background section, porcelain insulators are generally recycled by hammering to break the porcelain skirts, thereby separating the metal core rod from the porcelain skirts. This recycling method generates a large number of broken porcelain pieces, the sharp edges of which can easily injure workers. Furthermore, the flying porcelain pieces during hammering can also cause personal injury.

[0043] Therefore, the following embodiments provide a porcelain insulator recycling device and its working method. Taking into account the structural characteristics of porcelain insulators, the device uses a feeding unit to feed the porcelain insulators to be recycled one by one into the dismantling workbench and place them in the "C"-shaped supports. The dismantling machine uses a pneumatic hammer to strike one end of the insulator's core rod, causing the porcelain skirt part of the insulator to be broken by the shearing action of the C-shaped supports. The metal core rod then falls from the hollow part of the C-shaped supports into the discharge slide rail, realizing the separation of the metal core rod and the porcelain skirt fragments. The device can operate automatically without human intervention, thereby reducing the possibility of personal injury from porcelain fragments.

[0044] Example 1:

[0045] like Figure 1 As shown, the porcelain insulator recycling device includes:

[0046] The feeding unit 2 is used to receive the insulators to be recycled and transport the insulators to the dismantling workbench 4;

[0047] The dismantling unit includes a dismantling machine 3 and a dismantling workbench 4. When there are insulators to be recycled on the dismantling workbench 4, the air hammer of the dismantling machine 3 is activated to hammer the metal end of the insulator. In conjunction with the C-shaped support on the dismantling workbench 4, the porcelain skirt is broken and separated from the metal core rod. The broken porcelain pieces are collected by the discharge unit 1 and transported to the recycling box 5. The separated metal core rod falls into the discharge slide rail in the space below the C-shaped support for collection.

[0048] like Figure 2 and Figure 3 As shown, the feeding unit 2 has a conveying plane 21 that drives the insulator to move. A fixed groove 22 is provided at a set position on the conveying plane 21. One side of the fixed groove 22 has an opening 23 facing the disassembly workbench 4, and the other side has a transverse push plate 25 driven by the transverse cylinder 24. The movement direction of the transverse push plate 25 is perpendicular to the transport direction of the insulator 6.

[0049] In this embodiment, the conveying plane 21 has a strip groove for accommodating the metal head at one end of the insulator 6, so that the metal head at the other end of the insulator 6 is arranged vertically. The set position of the strip groove has a fixing groove 22, which is used to accommodate the lower half of the insulator 6. When the insulator 6 is driven by the conveying plane 21 to a position where it can enter the disassembly workbench 4, the lower half sinks into the fixing groove 22, the transverse cylinder 24 is activated, and the transverse push plate 25 pushes the insulator 6 through the opening 23 into the disassembly workbench 4, ready for disassembly.

[0050] In this embodiment, the conveying plane 21 is driven by a motor. The specific structure is not limited. It can be formed by using belts, rollers or any other components to transport insulators.

[0051] In this embodiment, the transverse push plate 25 is arc-shaped, and the curvature of the arc matches the diameter of the insulator 6.

[0052] It should be noted that the "lateral movement" involved in the lateral movement cylinder 24 and the lateral movement push plate 25 refers to the "lateral movement" based on the direction of travel of the insulator 6 on the conveying plane 21, that is, the movement direction of the lateral movement push plate 25 is perpendicular to the direction of travel of the insulator 6.

[0053] In this embodiment, the porcelain insulator is manually transferred to the conveying plane 21, where its metal cap sinks into the strip groove of the conveying plane 21. Driven by a motor, the porcelain insulator moves to a set position on the conveyor line, i.e., to the position of the fixed groove 22. Then, the lateral cylinder 24 actuates to push the porcelain insulator into the working area of ​​the dismantling machine 3. The feeding unit 2 has a certain transport distance, thereby isolating the manual operation area from the dismantling area and ensuring personal safety.

[0054] like Figure 4 As shown, the disassembly unit includes a disassembly machine 3 and a disassembly workbench 4. The disassembly workbench 4 is equipped with a feeding slide rail 32. One end of the feeding slide rail 32 is connected to the opening 23 on the conveying plane 21, and the other end is the disassembly position. Thus, the insulator 6 can be pushed from the fixed groove 22 into the feeding slide rail 32 by the transverse cylinder 24, and reach the disassembly position along the feeding slide rail 32. The disassembly machine 3 has a pneumatic hammer 31. The disassembly position is directly below the pneumatic hammer 31. A C-shaped support is provided at the disassembly position. The opening of the C-shaped support faces the feeding slide rail 32. The discharge slide rail 33 is located directly below the hollow part of the C-shaped support.

[0055] The disassembly workbench 4 has a hollow structure, and the hollow part is no smaller than the hollow part of the C-shaped support, which is used to allow the separated metal core rod to fall into the discharge slide rail 33 below.

[0056] When the insulator enters the C-type support along the feeding slide rail 32, the bottom surface of the insulator's porcelain shed is abutted by the C-type support, and the metal head at the bottom is located in the hollow part of the C-type support. The air hammer 31 is activated and strikes the metal head at the top of the insulator in a vertical direction. The impact force generated by the air hammer is transmitted from the metal head to the porcelain shed. Under the shearing action of the C-type support, the porcelain shed is broken. The broken porcelain pieces are distributed on the outer surface of the disassembly workbench 4, and the separated metal core rod falls from the hollow part of the C-type support into the discharge slide rail 33, where it is guided and collected.

[0057] The C-type support is designed according to the largest outer diameter of the metal column head; the outer side of the workbench is equipped with an outer protective cover to prevent debris from flying and dust from leaking out during the hammering and crushing process, ensuring personal and environmental safety.

[0058] Discharge unit 1 is a belt conveyor, with its starting end located in the space below the dismantling unit. It receives broken ceramic fragments and transports them to the recycling bin 5. The belt conveyor is existing technology. Because its starting end is located in the space below the dismantling unit, the belt conveyor is selected to transport materials in a low-to-high direction, for example... Figure 5 The structure shown.

[0059] The aforementioned device takes into account the structural characteristics of porcelain insulators. The feeding unit feeds the porcelain insulators to be recycled one by one into the dismantling workbench and places them in "C"-shaped supports. The dismantling machine's pneumatic hammer strikes one end of the insulator's core rod, causing the porcelain skirt to break under the shearing action of the C-shaped supports. The metal core rod then falls through the hollow part of the C-shaped supports into the discharge rail, achieving separation of the metal core rod and porcelain skirt fragments. This system can operate automatically without human intervention. The feeding unit separates the potentially scattering fragments from manual feeding operations, reducing the risk of personal injury from porcelain fragments. In actual engineering, the area where porcelain fragments might scatter is determined based on the specifications and dimensions of the insulators to be recycled, thus determining the travel distance of the feeding unit. Only a small amount of manual handling is used in the feeding and final transfer sections. The dismantling process, which is prone to injury, is physically isolated from manual operations, further reducing potential harm to personnel.

[0060] Example 2:

[0061] like Figure 7 As shown, the working method of the porcelain insulator recycling device includes the following steps:

[0062] (1) Porcelain insulator loading: Porcelain insulators are manually transferred to loading unit 2, and the porcelain insulators are moved to the dismantling area along with loading unit 2;

[0063] (2) Automatic clamping: When an incoming insulator is detected, the transverse cylinder of the feeding unit 2 moves to push the insulator along the feeding slide rail 32 into the C-type support of the dismantling unit;

[0064] (3) Umbrella skirt disassembly: The disassembly machine is started, and the hammer sleeve falls rapidly under the drive of the air hammer, hitting the metal column head part of the upper part of the insulator; the umbrella skirt fragments fall onto the belt of the discharge unit below; the metal cap falls onto the discharge slide rail below for recycling; the umbrella skirt fragments are transported by the discharge unit to the recycling box 5 for subsequent sorting and storage.

[0065] (5) Temporary storage: The recycling bin 5 first arrives at the automatic weighing station along the conveyor line, where it is scanned, weighed, and photographed. Then, it arrives at the stacker crane docking station along the conveyor line, where the stacker crane delivers the recycling bin to the sorting area or into the warehouse according to the dismantling process requirements.

[0066] Based on the structural characteristics of porcelain insulators, the feeding unit feeds the porcelain insulators to be recycled one by one into the dismantling workbench and places them in the "C"-shaped supports. The pneumatic hammer of the dismantling machine strikes one end of the insulator's core rod, causing the porcelain skirt part of the insulator to break under the shearing action of the C-shaped support. The metal core rod then falls from the hollow part of the C-shaped support into the discharge slide rail, realizing the separation of the metal core rod and the porcelain skirt fragments. This can be operated automatically without human intervention, thereby reducing the possibility of personal injury from porcelain fragments.

[0067] By using a feeding unit with a certain transport distance, the manual feeding area and the automatic dismantling area are separated. When dismantling is required, cylinders are used to push the insulators into the dismantling position one by one, ensuring that the flying ceramic pieces do not affect manual operation during the dismantling operation and reducing possible personal injury.

[0068] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of 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.
