Description

Technical Field

[0001] The present invention belongs to the field of transformer disassembly and recycling, and specifically relates to a flexible, intelligent and green transformer recycling production line. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, secondary coil and iron core (magnetic core). Its main functions include: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc.

[0003] Transformers are basic equipment for power transmission and distribution, and are widely used in industries such as industry, agriculture, transportation, and urban communities. There are about 17 million transformers in operation in my country, with a total capacity of about 11 billion kilovolt-amperes. Transformer losses account for about 40% of power transmission and distribution losses, and have great energy-saving potential. In order to accelerate the promotion and application of high-efficiency and energy-saving transformers, improve the efficiency of energy resource utilization, and promote green, low-carbon and high-quality development, in January 2021, the Ministry of Industry and Information Technology, the State Administration for Market Regulation, and the National Energy Administration jointly formulated the "Transformer Energy Efficiency Improvement Plan (2021-2023)".

[0004] Since transformers are always in high temperature and high pressure environment during use, they also have a service life, and the more complex and changeable the use environment is, the shorter the service life is. According to the regulations of the power industry, transformers must be dismantled and destroyed after their service life expires, and sold according to different categories of waste materials. This can prevent illegal vendors from recycling and refreshing them and then re-selling them on the market, fundamentally avoiding the potential safety hazards of electricity use caused by the reuse of scrapped transformers.

[0005] Transformer disassembly and recycling is a typical multi-variety, small-batch operation mode, and it mainly faces the following problems in production: 1. There is a large amount of manual work in product manufacturing, and the production efficiency and degree of automation are low; 2. Disassembly operations are mainly single-product, independent production operations, and the process coordination ability is insufficient; 3. There is a lack of online statistical means, and it is difficult to track key indicators such as oil filtration time in real time, and the production process control ability is low.

[0034] like Figure 1 to Figure 3 As shown, the present invention provides a transformer flexible intelligent green recycling production line, including an oil drain chain plate conveyor line 1, a turning machine 2 and a digital panel;

[0040] The bend in the middle of the oil leakage chain plate conveyor line 1 is the copper core offline work area 6, and a third crane 8 is installed above the copper core offline work area 6. The manual hole opening work area, the cover opening station, and the copper core offline work area 6 are all arranged on the oil leakage chain plate conveyor line 1;

[0041] A cotton baler 7 is installed at the discharge end of the oil-draining chain plate conveyor line 1 , and the digital panel is electrically connected to the oil-draining chain plate conveyor line 1 , the turning machine 2 , the weight sensor, and the transformer housing conveyor line 4 .

[0042] As a preferred embodiment of the present invention, the turning machine 2 includes a base, two support rings 9, and a driving ring 10 arranged between the two support rings 9. The two support rings 9 are parallel to the driving ring 10. The two support rings 9 are fixedly connected to the driving ring 10 through a support rod 11. The left and right sides of the support ring 9 are provided with a transverse limiting wheel 12 that slides relative to the outer side of the support ring 9. The front and rear sides of the support ring 9 are provided with a longitudinal limiting wheel 13 that slides relative to the inner side of the support ring 9. The transverse limiting wheel 12 and the longitudinal limiting wheel 13 are both arranged on the base. A driving motor 14 is also arranged on the base.

The outer side of the driving ring 10 is provided with a belt 16 that is transmission-connected to the driving wheel 15. A servo lifting system 17 is installed on the upper and lower support rods 11 of the turning machine 2.

The telescopic ends of the servo lifting system 17 are fixedly connected to the clamping plate chain line 18.

[0043] As a preferred embodiment of the present invention, the discharge end of the transformer casing conveyor line 4 is provided with a slide rail 19 extending into the oil leakage chain plate conveyor line 1, the slide rail 19 and the oil leakage chain plate conveyor line 1 are perpendicular to each other, a movable plate chain line 20 is provided on the slide rail 19, and a cylinder is provided at one end of the slide rail 19 away from the oil leakage chain plate conveyor line 1, and the output end of the cylinder is fixedly connected to the movable plate chain line 20.

[0044] As a preferred embodiment of this embodiment, oil collecting tanks are provided below the oil-draining chain plate conveyor line 1 and the transformer casing conveyor line 4.

[0045] As a preferred embodiment of this embodiment, the transformer flexible intelligent green recycling production line pulsates one transformer position at a fixed period.

[0046] The operation process of the transformer flexible intelligent green recycling production line of the present invention is as follows:

[0047] First, the material (transformer to be disassembled) is delivered to the production site by a flatbed truck, and then the material is manually unloaded to the production preparation area by a forklift. Then, the flexible, intelligent, green recycling production line of the transformer of the present invention is started, and the transformer placed in the production preparation area is moved to the oil drain chain plate conveyor line 1 by the first crane 3. During the lifting process, the system automatically records the overall weight of the transformer. The transformer moves forward with the oil drain chain plate conveyor line 1. When it moves to the manual hole opening work area, the staff takes the plasma cutter to complete the transformer hole opening. After the hole opening is completed, the line body automatically moves forward one station and waits for the next station to go online. The transformer leaks oil through the hole opening, and the leaked oil is collected in the oil collecting tank through the through hole on the oil drain chain plate conveyor line 1. After the oil is drained for a period of time, the transformer moves to the cover opening station and the cover is opened manually. After that, the copper core is lifted from the transformer after the cover is opened by the second crane 5, and the copper core is placed on the oil drain chain plate conveyor line 1, and then the transformer shell with the copper core removed is placed on the transformer shell conveyor line 4 by the second crane 5. The overturning machine 2 on the transformer casing conveying line 4 overturns the transformer to allow for more complete oil leakage, and then the overturned transformer is re-conveyed to the oil leakage chain plate conveying line 1 .

[0048] The process of flipping the transformer shell by the flipping machine 2 is as follows: according to the size of the transformer shell, the relative positions of the upper and lower clamping plate chain lines 18 are adjusted by the upper and lower servo lifting motors, and the transformer shell is clamped and fixed for subsequent flipping. After the clamping plate chain line 18 fixes the transformer shell, the drive motor 14 is started. The drive motor 14 drives the support ring 9 and the drive ring 10 to rotate 180° through the drive wheel 15 and the belt 16, and then controls the upper clamping plate chain line 18 to move up to release the fixation of the transformer shell. Under the transmission action of the clamping plate chain line 18, the flipped transformer shell enters the movable plate chain line 20, and the movable plate chain line 20 is re-integrated into the oil leakage chain plate conveyor line 1 under the action of the cylinder, thereby continuing to transport the flipped transformer shell along the oil leakage chain plate conveyor line 1.

[0049] When the copper core on the oil-draining chain conveyor line 1 moves to the copper core offline work area 6, the copper core is offlined by the third crane 8. When the overturned transformer shell on the oil-draining chain conveyor line 1 moves to the discharge end, the overturned transformer shell is hoisted into the cotton baler 7 by the first crane 3, and the cotton bale is forked out by a forklift after baling.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution, which should be included in the protection scope of the present invention.
