Description

Technical Field

[0001] The invention relates to the technical field of cable manufacturing, and in particular to an automated device for removing free charged particles from cables. Background Art

[0002] As a conductor used to transmit electrical energy or signals, cables need to be irradiated during manufacturing to improve their performance. The main purpose is to significantly enhance their comprehensive performance to meet various complex and special usage requirements.

[0003] Irradiation treatment has many advantages: First, it can improve heat resistance. After treatment, the molecular structure of the cable insulation material changes, and it can withstand higher temperatures, enhance its stability and service life in high temperature environments (such as steel mills, chemical plants, etc.), and ensure the stability and safety of power transmission; second, it can enhance mechanical properties, increase the strength and toughness of cable insulation materials, make them more resistant to wear, stretching and bending, reduce the risk of damage during use, and enable them to better adapt to complex working conditions in application scenarios with frequent movement or bending such as cranes and automated production lines; third, it can improve chemical resistance, allowing cables to more effectively resist the erosion of chemical substances, and is suitable for corrosive places such as chemical companies or marine environments to improve its corrosion resistance; fourth, it can improve electrical performance, reduce the dielectric loss of insulating materials, enhance insulation resistance, and thereby improve the electrical performance and transmission efficiency of cables; fifth, it can reduce material aging, slow down the aging rate of cables during use, and extend their service life.

[0004] When the cable is irradiated, residual charged particles will be left in the cable due to the following reasons. First, the ionization effect during the irradiation process. Irradiation will cause the molecules in the cable insulation material to ionize, thereby generating charged particles. However, after the irradiation, these charged particles may not be able to recombine or dissipate quickly, thus causing residual charge. Second, the polarization phenomenon of the material. Irradiation will change the molecular structure and electrical properties of the insulating material, making it easier to polarize. Charge may accumulate on the surface of the polarized material. Third, the trap effect. There may be some physical or chemical defects inside the insulating material, thus forming the so-called "traps". The charges generated by irradiation may be captured by these traps, making it difficult to move and dissipate freely, ultimately resulting in the existence of residual charges. Such residual charged particles may have a certain impact on the performance and use of the cable, such as affecting its electrical performance, causing partial discharge, etc.

[0005] In summary, the problem of residual charge after cable irradiation treatment cannot be ignored, and it is urgent to solve this problem. Only by eliminating the impact of residual charge as soon as possible can the performance and safety of cables be further improved and the healthy development of related industries be promoted.

DETAILED DESCRIPTION

[0035] Example

[0036] Please refer to Figure 1-Figure 7, an automated device for removing free charged particles from a cable, comprising: a first shell 3, provided with a processing channel 9, and the processing channel 9 passes through the first shell 3; an X-ray emitter 16, used to emit soft X-rays to the processing channel 9; and a conveying structure, comprising a first conveying structure 1 and a second conveying structure 7, the first conveying structure 1 is arranged at one end of the processing channel 9, and the second conveying structure 7 is arranged at the other end of the processing channel 9, the first conveying structure 1 is used to convey the cable to be processed to the processing channel 9, and the second conveying structure 7 is used to output the cable after processing in the processing channel 9.

[0037] Preferably, the first shell 3 is made of thermosetting epoxy resin, unsaturated polyester resin, phenolic resin, diallyl phthalate resin, thermoplastic epoxy resin, nylon resin, aromatic nylon resin, polybutylene terephthalate resin, polyethylene terephthalate resin, polyacetate resin, polyphenylene sulfide resin, polyphenylene ether resin, liquid crystal polymer or methylpentene polymer.

[0038] When the present application is removing the free charged particles of the cable, the cable to be processed will first be placed steadily on the first conveying structure 1. Then, relying on the powerful and stable conveying capacity of the first conveying structure 1, the cable is accurately and accurately conveyed to the processing channel 9. At the same time, the X-ray emitter begins to play a key role, and it will produce soft X-rays. This soft X-ray can excite the particles in the air or / and the cable to be charged. Subsequently, the charged particles excited by the X-ray emitter will react with the charged particles originally existing in the cable itself. Through such neutralization, the charged particles on the cable are successfully removed. During the whole process, the first conveying structure 1 continuously performs input operations, which effectively promotes the smooth transition of the cable in the processing channel 9 to the second conveying structure 7. Then, under the efficient conveying action of the second conveying structure 7, the processed cable is output. By repeating the above series of operation processes continuously, the automated batch processing of cables can be smoothly realized. The present application successfully achieved the goal of neutralizing the residual charge of the cable in the above manner. This achievement effectively ensures the stability of the cable's performance, enabling it to maintain excellent performance during subsequent use, avoiding various potential problems caused by residual charge, and greatly improving the quality and reliability of the cable.

[0039] Specifically, the first conveying structure 1 and the second conveying structure 7 both use belt conveyors. As a common material conveying equipment, belt conveyors are mainly composed of conveyor belts, drive devices, rollers, rollers, tensioning devices, frames and other components. Its working principle is to use the drive device to drive the roller to rotate, and then the roller drives the conveyor belt to move, so as to achieve continuous transportation of materials on the conveyor belt. The material is placed on the conveyor belt and will be transported from one position to another as the conveyor belt moves.

[0040] Choosing a belt conveyor as the conveying structure has at least the following advantages:

[0041] Strong conveying capacity: It can continuously and massively convey all kinds of materials, whether they are bulk materials or piece items.

[0042] Long conveying distance: It can realize long-distance material transportation, effectively reduce the transfer links, and greatly improve work efficiency.

[0043] Simple structure: installation, maintenance and operation are relatively easy, which significantly reduces the cost of use and maintenance difficulty.

[0044] Good versatility: suitable for a variety of materials of different types and properties, such as ore, coal, grain, etc.

[0045] Smooth and orderly operation: materials are relatively stable during transportation, which greatly reduces material breakage and spillage.

[0046] High degree of automation: It can work in coordination with other automated equipment to achieve automated control of the entire production process.

[0047] Relatively low cost: Compared with other transportation methods, its construction and operation costs are relatively economical.

[0048] The X-ray emitter 16 is a device capable of generating X-rays and belongs to the prior art. The following methods can be used to enable the X-ray emitter to generate soft X-rays:

[0049] Adjusting the tube voltage: Reducing the tube voltage can reduce the acceleration energy of electrons, thereby reducing the overall energy of the generated X-rays and increasing the relative proportion of soft X-rays. For example, the tube voltage can be reduced from a conventional high value (such as tens of kilovolts) to a lower value (such as several to dozens of kilovolts).

[0050] Choose the right target material: Different target materials' atomic numbers and physical properties will affect the generation of X-rays. Choosing a target material with a lower atomic number, such as beryllium (Be) or carbon (C), is relatively easy to generate more soft X-rays.

[0051] Controlling electron beam current: Properly reducing the electron beam current (i.e., tube current) can affect the intensity and energy distribution of X-rays to a certain extent, and help increase the output of soft X-rays.

[0052] Optimizing the anode angle: Adjusting the angle and shape of the anode can change the way and location of electrons hitting the anode, thereby affecting the emission characteristics of X-rays and potentially increasing the production of soft X-rays.

[0053] Use filters: Use appropriate filter materials on the X-ray emission path to filter out high-energy X-rays, thereby relatively increasing the proportion of soft X-rays.

[0054] It should be noted that when adjusting the X-ray emitter 16, it is necessary to follow relevant safety regulations and operating guidelines to ensure the safety of operators and the normal operation of the equipment.

[0055] In some embodiments of the present invention, the X-ray emitter 16 has an anode portion 21, a second housing 19 is disposed outside the anode portion 21, and a sealed cooling chamber 20 is formed between the second housing 19 and the anode portion 21;

[0056] The cooling chamber 20 is connected to a cooling liquid supply assembly 14 .

[0057] In the above embodiment, the anode part 21 of the X-ray emitter 16 generates a lot of heat when working. At this time, the coolant supply assembly 14 plays an important role, which can inject coolant into the cooling cavity 20, thereby effectively cooling the anode part 21. This design enhances the stability and durability of the device and is more practical.

[0058] For example, during long-term continuous operation, good cooling can prevent the anode portion 21 from being damaged due to overheating, ensuring the normal operation of the X-ray emitter 16, thereby improving the working efficiency and reliability of the entire system.

[0059] In some embodiments of the present invention, the cooling liquid supply assembly 14 includes a cooling liquid storage tank 1401, a delivery pump 1402 and a delivery pipe 1403 which are connected in sequence, and one end of the delivery pipe 1403 away from the delivery pump 1402 is connected to the cooling chamber 20;

[0060] The coolant storage tank 1401 is also provided with a pipe 18 connected to the cooling chamber 20 .

[0061] In the above embodiment, sufficient coolant is stored in the coolant storage tank 1401. Under the strong action of the delivery pump 1402, the coolant in the coolant storage tank 1401 will smoothly enter the cooling chamber 20 through the delivery pipe 1403, thereby efficiently cooling the anode part 21 of the X-ray emitter 16. In addition, after completing the cooling task, the coolant in the cooling chamber 20 can flow back to the coolant storage tank 1401 through the pipeline 18, thereby realizing the recycling of the coolant. This recycling design not only saves resources, but also reduces costs, while ensuring the continuous and stable cooling work.

[0062] For example, during long-term continuous operation, this circulating cooling system can always maintain a good cooling effect and ensure the stable operation of the X-ray emitter 16.

[0063] Optionally, insulating oil is selected as the coolant.

[0064] In some embodiments of the present invention, the delivery pipe 1403 includes a spiral portion, and a heat dissipation blade 22 is disposed on the outer side of the spiral portion.

[0065] In the above embodiment, the coolant exchanges heat with the outside air by means of the heat dissipation blades 22, thereby achieving the purpose of cooling the coolant. Among them, the unique design of the spiral part plays an important role, which can prolong the contact time between the coolant and the air (extend the flow distance of the coolant), thereby making the cooling effect of the coolant more outstanding.

[0066] For example, when running for a long time in a high temperature environment, this optimized design allows the coolant to fully dissipate heat, ensuring that it always maintains good cooling performance, providing strong protection for the stable operation of the equipment.

[0067] In some embodiments of the present invention, the coolant supply assembly 14 further includes a first fan 15, and the first fan 15 is used for heat dissipation and temperature reduction of the spiral portion.

[0068] In the above embodiment, the first fan 15 supplies air to the spiral portion, which greatly optimizes the heat dissipation conditions of the coolant in the spiral portion, thereby making the heat dissipation effect of the coolant better.

[0069] For example, in an actual working scenario, when the device continuously runs and generates a large amount of heat, the first fan 15 continuously delivers wind to the spiral part. The strong airflow accelerates the heat exchange between the coolant and the outside air, thereby quickly taking away the heat in the coolant, ensuring that the coolant can always cool the device in an efficient state, maintain the stable operation of the device, and extend the service life of the device.

[0070] In some embodiments of the present invention, the first housing 3 is further provided with a mounting cavity 10, and the X-ray emitter 16 and the coolant supply assembly 14 are both disposed in the mounting cavity 10;

[0071] The first housing 3 is provided with a first circulation hole group 4 for providing air circulation when the first fan 15 is working.

[0072] In the above embodiment, the X-ray emitter 16 and the coolant supply assembly 14 are both arranged in the installation cavity 10. Through such a layout, the X-ray emitter, the coolant supply assembly 14 and the first housing 3 are integrated into one. This integrated design brings many advantages, significantly making the structure of the present application more compact and greatly reducing the space occupied by the device.

[0073] For example, in a workplace with limited space, this compact structure can better adapt to the environment and will not cause space congestion due to its large size. Moreover, the compactness of the structure can also reduce the length of the connecting lines and pipelines 18 between components, reduce the loss of energy transmission, and improve the operating efficiency of the entire system. At the same time, the integrated design also facilitates the overall installation, commissioning and maintenance of the equipment, reducing the complexity and cost of operation.

[0074] Specifically, the first circulation hole group 4 is provided with a dustproof net, which can filter out impurities and dust in the air.

[0075] In some embodiments of the present invention, the first housing 3 is further provided with a negative pressure generating chamber 11, and the cable placement plane of the processing channel 9 is provided with a through hole 13 connected to the negative pressure generating chamber 11, and the number of the through holes 13 is multiple;

[0076] The negative pressure generating chamber 11 is provided with a second fan, and the first housing 3 is provided with a second circulation hole group 8 for circulating the airflow of the second fan.

[0077] In the above embodiment, the second fan plays a key role, which can form a negative pressure state in the negative pressure generating chamber 11. Under the influence of this negative pressure environment, the charged particles in the processing channel 9 will flow toward the through hole 13. As a result, the charged particle group can form a tight wrap around the cable, so that more charged particles are in contact with the cable. This increase in contact significantly improves the removal effect of the charged particles on the cable, making the cable treatment more thorough and efficient.

[0078] For example, in a production line that processes cables on a large scale, this optimized design can ensure that each cable can fully remove charged particles and improve product quality consistency. Moreover, better removal effects can extend the service life of cables, reduce maintenance costs, and bring higher economic benefits and market competitiveness to related industries.

[0079] Specifically, the second circulation hole group 8 is provided with a dustproof net, which can filter out impurities and dust in the air.

[0080] In some embodiments of the present invention, a first shielding shell 2 and a second shielding shell 5 are respectively provided at both ends of the above-mentioned processing channel 9, the above-mentioned first shielding shell 2 is located above the above-mentioned first conveying structure 1, and forms a first channel with the above-mentioned first conveying structure 1, and the above-mentioned second shielding shell 5 is located above the above-mentioned second conveying structure 7, and forms a second channel with the above-mentioned second conveying structure 7.

[0081] In the above embodiment, the first shielding shell 2 and the second shielding shell 5 have a shielding effect, which can reduce the loss rate of charged particles in the processing channel 9. When the charged particles generated by the X-ray emitter 16 flow into the first shielding shell 2 and the second shielding shell 5, they can also contact the cables in the first shielding shell 2 and the second shielding shell 5, further improving the removal effect of free charged particles on the cables.

[0082] In some embodiments of the present invention, a port of the first channel away from the processing channel 9 and a port of the second channel away from the processing channel 9 are both provided with a rubber door curtain 6 .

[0083] In the above embodiment, the rubber door curtain 6 can not only prevent the staff from being damaged by soft X-rays, but also prevent the entry of dust to a certain extent, thereby reducing the maintenance cost of the machine application.

[0084] In some embodiments of the present invention, the installation cavity 10, the negative pressure generating cavity 11 and the rubber door curtain 6 are all provided with lead plates.

[0085] In the above embodiment, the lead plate can absorb X-rays to prevent the operator from being injured.

[0086] Specifically, a shielding plate 17 is symmetrically arranged at the generating end of the X-ray emitter 16 to adjust the generating range of the X-ray emitter 16. A power supply 12 is arranged in the negative pressure generating chamber 11 to supply power to the power supply device in the present application.

[0087] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
