Description

Technical Field

[0001] This application belongs to the technical field of metal surface treatment or cleaning, and particularly relates to an electro-explosion degreasing method and a device for implementing the electro-explosion degreasing method. Background Art

[0002] In modern industrial production, the removal of oil stains on the surface of metal devices is an extremely crucial pretreatment process. From the manufacturing of precision electronic components to the processing of large mechanical parts, many industries have extremely strict requirements for the surface cleanliness of metal devices. Oil stain residues will not only affect the appearance of products, but also have a serious impact on their performance, reliability, and service life.

[0003] Traditional degreasing methods have significant drawbacks. Chemical degreasing methods, such as using degreasing agents such as strong acids, strong alkalis, and surfactants, can achieve oil stain removal to a certain extent. However, the use of chemical agents not only brings high costs, but also causes serious environmental pollution. Improper treatment is likely to cause environmental problems such as water pollution and soil acidification. At the same time, chemical agents have strong corrosiveness to the metal devices themselves, which may reduce the strength and service life of the devices. Physical degreasing means also face challenges. Electrostatic degreasing is limited by the requirements for the shape and conductivity of the devices. For metal parts with irregular shapes or poor conductivity, the effect of electrostatic degreasing is greatly reduced, and the equipment investment is large and the operating cost is high. Summary of the Invention

[0004] In order to overcome the deficiencies in the poor degreasing effect and high cost of metal device surfaces in the prior art, this application provides an electro-explosion degreasing method and a device for implementing the electro-explosion degreasing method, which can reduce the degreasing cost on the premise of ensuring the degreasing effect on the surface of metal devices.

[0005] To achieve the above object, this application adopts the following technical solutions: An electro-explosion degreasing method includes the following steps: S100: Place the device to be degreased and a metal wire for electro-explosion in an insulating liquid; S200: Vaporize the metal wire through a high-voltage pulse power supply and release shock waves, and strip the waste oil attached to the surface of the device to be degreased through the insulating liquid; S300: Repeat the steps of S100 - S200 to continuously degrease the device to be degreased.

[0006] After adopting the above technical solution, the principle of this application is as follows: the metal wire instantaneously vaporizes under the action of a high-voltage pulsed power supply, releasing a high-energy shock wave; the shock wave is transmitted through the insulating liquid medium to the surface and internal structure of the device to be degreased, stripping the waste oil attached to the surface; the stripped waste oil gradually undergoes solid-liquid separation under the action of the shock wave, thereby achieving efficient degreasing; this application has the following advantages: the metal wire is vaporized by the high-voltage pulsed power supply to release a shock wave, and the shock wave propagates in the insulating liquid, which can effectively strip the waste oil attached to the surface of the device to be degreased. For some metal devices with complex structures, such as devices with deep holes, blind holes or fine gaps, the shock wave can act on the oil stain more fully. Compared with methods such as mechanical cleaning, it can better remove the oil stain, reduce the oil stain residue, and ensure the degreasing effect on the surface of the metal device. And when the shock wave is used to degrease the device to be degreased through the insulating liquid, it can avoid damaging the internal structure of the device and achieve degreasing without mechanical damage.

[0007] Further, after step S200, it further includes S210: the waste oil enters the waste oil collection tank after being stripped from the device to be degreased.

[0008] Adopting the foregoing technical solution, the waste oil collection tank can timely collect the stripped waste oil, prevent the waste oil from adhering to the cleaned part or other components again in the insulating liquid, and ensure the continuity and stability of the degreasing effect. At the same time, the centralized collection of waste oil facilitates the subsequent unified treatment of the waste oil, improving the cleanliness and orderliness of the entire degreasing process.

[0009] Further, in step S100, the device to be degreased and the metal wire are completely immersed in the insulating liquid.

[0010] Adopting the foregoing technical solution, when the device to be degreased and the metal wire are completely immersed in the insulating liquid, the shock wave generated by the electro-explosion of the metal wire can propagate uniformly in the insulating liquid and act on the surface of the device to be degreased in all directions. This enables each part of the device surface to be affected by the shock wave of the same intensity, thereby ensuring the uniformity of the degreasing effect and avoiding the problem of oil stain residue caused by insufficient contact of the shock wave with some parts of the device surface. And the device to be degreased and the metal wire are completely immersed in the insulating liquid, and using the insulating property of the insulating liquid can effectively prevent safety accidents such as electric shock during the electro-explosion process.

[0011] A device for implementing the electro-explosion degreasing method, including a box body, a cavity for accommodating an insulating liquid, a device to be degreased and an electro-explosion device is provided in the box body, the electro-explosion device includes a fixing member and a movable member sleeved outside the fixing member and displaced relative to the fixing member, a plurality of clamping members for clamping a metal wire are fixedly provided on the movable member, and an electrode group for intermittently conducting the clamping members is provided on the fixing member, so that when a single group of clamping members is displaced to the conducting position of the electrode group, the metal wire is conducted and an electro-explosion occurs.

[0012] Adopting the foregoing technical solution, the principle of this solution is as follows: The electrode group on the fixing member of the electro-explosion device consists of two electrodes that can conduct electricity with each other. Multiple clamping members for clamping metal wires are arranged on the movable member. The clamping members clamp the metal wires and move relative to the fixing member. When the movable member moves to the position where the clamping members are electrically connected to the electrode group, electrical conduction is generated between the electrode group, the clamping members, and the metal wires, causing the metal wires to instantly vaporize and generate shock waves after being subjected to high-voltage pulsed current. The unvaporized metal wires are still fixed on the upstream clamping members and continue to move as the movable member moves, so that the metal wires can continuously undergo electro-explosion to complete the oil removal operation. The advantages of this solution are as follows: After a group of metal wires complete the electro-explosion oil removal, the next group of clamping members can continue to move to the position where they are electrically connected to the electrode group and then immediately perform the next electro-explosion, realizing the continuity of the oil removal operation, avoiding the time consumed by frequently replacing metal wires in the traditional method, and greatly improving the oil removal efficiency. Moreover, through the displacement of the movable member, the metal wires can generate electro-explosion at specific positions, enabling the shock waves to act on the surface of the device to be deoiled from a specific angle. When dealing with different devices to be deoiled, the overall oil removal effect and efficiency can be improved. In addition, parameters such as the displacement speed, frequency of the movable member, and the time interval of electrical connection of the electrode group can be controlled to flexibly adjust the frequency and intensity of electro-explosion to adapt to different types and degrees of oil contamination of the devices to be deoiled, improving the applicability and operation flexibility of the device. The device adopts a box structure, accommodating the insulating liquid, the device to be deoiled, and the electro-explosion device in the cavity. This closed design can effectively prevent the possible splashes, shock waves, etc. generated during the electro-explosion process from causing harm to the operators, and at the same time reduce the interference of external factors on the oil removal process, improving the safety of the operation.

[0013] Further, the movable member rotates around the center of the fixing member, and the movable member and the fixing member are concentrically arranged.

[0014] Adopting the foregoing technical solution, the movable member rotates around the center of the fixing member, so that during the rotation of the metal wires, electro-explosion can occur at different angles with the center of the fixing member as the center. This can make the shock waves act more uniformly on the surface of the device to be deoiled. Regardless of the shape of the device, the oil can be removed more comprehensively and uniformly, effectively avoiding the situation of incomplete local oil removal, and further improving the consistency and stability of the oil removal effect.

[0015] Further, the fixing member includes a planar section and a curved section. The movable member is composed of multiple track plates, and the movable member moves around the outer surfaces of the planar section and the curved section of the fixing member. The electrode group is arranged on the planar section of the fixing member.

[0016] With the foregoing technical solution, by designing the fixing member to have a flat section and a curved section, the electrode group can be arranged on the flat section of the fixing member, so that the clamping member on the movable member is electrically connected to the electrode group when it moves to the flat section, generating an electric explosion. The surface of the flat section is relatively flat, which is conducive to forming a stable and reliable electrical contact between the electrode group and the clamping member, ensuring the smooth progress of the electric explosion.

[0017] Furthermore, the electrode group is arranged on one side of the fixing member facing the device to be degreased.

[0018] With the foregoing technical solution, the electrode group is arranged on the side facing the device to be degreased, so that the shock wave generated by the electric explosion of the metal wire can propagate more directly towards the device to be degreased. This can minimize the energy loss of the shock wave during propagation, make the shock wave act on the surface of the device to be degreased with stronger energy, more effectively strip the oil stain, thereby improving the degreasing efficiency and shortening the degreasing time. Since the shock wave can act more directly on the device to be degreased, for some stubborn oil stains and oil stains on the surface of complex structures, it can more powerfully impact and destroy the adhesion between the oil stain and the device surface, ensuring that the oil stain is removed more thoroughly, further improving the degreasing effect, and ensuring that the surface of the device to be degreased reaches a higher cleanliness.

[0019] Furthermore, it further includes a wire supply mechanism, and the wire supply mechanism is arranged outside the box body.

[0020] With the foregoing technical solution, the wire supply mechanism is arranged outside the box body, so that the operator does not need to open the box body when replacing or replenishing the metal wire, and can directly operate outside. This greatly simplifies the replacement process of the metal wire, saves operation time, and improves work efficiency. Especially in continuous degreasing operations, it can quickly and conveniently replenish the metal wire for the device, ensure the continuity of the degreasing work, and avoid downtime waiting time caused by metal wire shortage. And the wire supply mechanism can also avoid being affected by the electric explosion in the box body, protecting the safety of the wire supply mechanism.

[0021] Furthermore, the cavity includes a first chamber for accommodating the device to be degreased and a second chamber for accommodating the electric explosion device. The first chamber and the second chamber are connected through a guiding channel. A waste oil collection tank for recovering waste oil and a separation device for separating waste oil are arranged in the second chamber.

[0022] With the foregoing technical solution, in the first chamber, the device to be degreased can be placed more stably without being interfered by the operation of the electro-explosion device; while the second chamber is specifically used for the installation and operation of the electro-explosion device, making the electro-explosion process more stable and reliable. The two chambers are connected through a guiding channel, ensuring that the shock wave can effectively be transmitted from the second chamber to the first chamber and act on the device to be degreased, which not only improves the degreasing efficiency but also ensures the degreasing quality. A waste oil collection tank is arranged in the second chamber, which can timely collect the waste oil peeled off from the device to be degreased and flowing in through the guiding channel. The electro-explosion device is placed in an independent second chamber, separated from the waste oil generated by the device to be degreased. The waste oil may contain impurities or have certain corrosiveness. Through this partition design, it can effectively prevent the waste oil from eroding and damaging the electro-explosion device, extend the service life of the device, and reduce the costs of device maintenance and replacement.

[0023] Further, a plurality of clamping members are arranged at intervals in the up-and-down direction on the movable member, so that the plurality of clamping members spaced up and down clamp a plurality of metal wires spaced up and down to generate shock waves distributed up and down for degreasing operations.

[0024] With the foregoing technical solution, a plurality of clamping members spaced up and down can clamp a plurality of metal wires spaced up and down, generating shock waves distributed up and down during electro-explosion. This enables all parts of the device to be degreased to be affected by the shock wave in the vertical direction. Especially for some devices with a certain height or thickness, it can more comprehensively remove the oil stains on its surface, avoiding the problem of incomplete degreasing caused by the limited action range of the shock wave, and greatly improving the comprehensiveness and uniformity of the degreasing effect. When a plurality of metal wires generate electro-explosion simultaneously, forming multiple shock wave sources, compared with the shock wave generated by a single metal wire, it can generate a greater impact force on the oil stains in a shorter time, accelerating the peeling speed of the oil stains. More oil stains can be processed in one degreasing operation, reducing the time required for degreasing and improving the efficiency of the entire degreasing operation.

[0029] The technical solutions of this application will be described in detail below with specific embodiments. These specific embodiments can be combined or replaced according to the actual situation. For the same or similar concepts or processes, they may not be repeated in some embodiments.

[0030] As Figures 1 to 3 shown, this application provides an electro-explosion degreasing method, including the following steps: S100: Place the device 1 to be degreased and the metal wire 21 for electro-explosion in an insulating liquid; S200: Vaporize the metal wire 21 through a high-voltage pulse power supply and release shock waves, and strip the waste oil attached to the surface of the device 1 to be degreased through the insulating liquid; S300: Repeat the steps of S100 - S200 to continuously degrease the device 1 to be degreased.

[0031] After adopting the above technical solution, the principle of this application is as follows: The metal wire 21 is instantaneously vaporized under the action of a high-voltage pulse power supply, releasing a high-energy shock wave; the shock wave is transmitted through the insulating liquid medium to the surface and internal structure of the oil-removing device 1 to strip the waste oil attached to the surface; the stripped waste oil gradually undergoes solid-liquid separation under the action of the shock wave, thereby achieving efficient oil removal; this application has the following advantages: The metal wire 21 is vaporized by the high-voltage pulse power supply to release a shock wave, and the shock wave propagates in the insulating liquid, which can effectively strip the waste oil attached to the surface of the oil-removing device 1. For some metal devices with complex structures, such as devices with deep holes, blind holes or fine gaps, the shock wave can act more fully on the oil stains. Compared with methods such as mechanical cleaning, it can better remove the oil stains, reduce the oil stain residue, and ensure the oil removal effect on the surface of the metal device. And when the shock wave is used to remove oil from the oil-removing device 1 through the insulating liquid, it can avoid damaging the internal structure of the device and achieve oil removal without mechanical damage.

[0032] Specifically, the oil-removing device 1 is a waste transformer.

[0033] Further, after step S200, there is also S210: The waste oil enters the waste oil collection tank 5 after being stripped from the oil-removing device 1.

[0034] Adopting the foregoing technical solution, the waste oil collection tank 5 can timely collect the stripped waste oil, avoid the waste oil from reattaching to the cleaned part or other components in the insulating liquid, and ensure the continuity and stability of the oil removal effect. At the same time, centralized collection of waste oil facilitates subsequent unified treatment of the waste oil, improving the cleanliness and orderliness of the entire oil removal process.

[0035] Further, in step S100, the oil-removing device 1 and the metal wire 21 are completely immersed in the insulating liquid.

[0036] Adopting the foregoing technical solution, when the oil-removing device 1 and the metal wire 21 are completely immersed in the insulating liquid, the shock wave generated by the electro-explosion of the metal wire 21 can propagate uniformly in the insulating liquid and act on the surface of the oil-removing device 1 in all directions. This enables each part of the device surface to be affected by the shock wave of the same intensity, thereby ensuring the uniformity of the oil removal effect and avoiding the problem of oil stain residue caused by insufficient contact of some device surfaces with the shock wave. And the oil-removing device 1 and the metal wire 21 are completely immersed in the insulating liquid, and using the insulating property of the insulating liquid can effectively prevent safety accidents such as electric shock during the electro-explosion process.

[0037] A device for implementing an electro-explosion oil removal method, comprising a box body 3. A cavity 31 for accommodating an insulating liquid, a device 1 to be deoiled, and an electro-explosion device 2 is provided inside the box body 3. The electro-explosion device 2 includes a fixing member 22 and a movable member 23 sleeved outside the fixing member 22 and displaceable relative to the fixing member 22. A plurality of clamping members 24 for clamping a metal wire 21 are fixedly provided on the movable member 23. An electrode group 25 for intermittently conducting the clamping members 24 is provided on the fixing member 22, so that when a single group of clamping members 24 is displaced to the conducting position of the electrode group 25, the metal wire 21 is conducted and an electro-explosion is generated.

[0038] Adopting the foregoing technical solution, the principle of this solution is as follows: The electrode group 25 on the fixing member 22 of the electro-explosion device 2 consists of two electrodes capable of conducting with each other. A plurality of clamping members 24 for clamping the metal wire 21 are provided on the movable member 23. The clamping members 24 clamp the metal wire 21 and move relative to the fixing member 22. When the movable member 23 moves to the position where the clamping member 24 conducts with the electrode group 25, the electrode group 25 conducts through the clamping member 24 and the metal wire 21, causing the metal wire 21 to instantaneously vaporize and generate a shock wave under the action of a high-voltage pulsed current. The unvaporized metal wire 21 is still fixed on the upstream clamping member 24. As the movable member 23 continues to move, the metal wire 21 can continuously undergo electro-explosion to complete the oil removal operation. The advantages of this solution are as follows: After a group of metal wires 21 complete the electro-explosion oil removal, the next group of clamping members 24 can continue to move to the conducting position of the electrode group 25, and the next electro-explosion can be carried out immediately, realizing the continuity of the oil removal operation, avoiding the time consumed by frequently replacing the metal wire 21 in the traditional method, and greatly improving the oil removal efficiency. And through the displacement of the movable member 23, the metal wire 21 can generate an electro-explosion at a specific position, allowing the shock wave to act on the surface of the device 1 to be deoiled from a specific angle. The overall oil removal effect and efficiency can be improved when dealing with different devices 1 to be deoiled. In addition, the frequency and intensity of the electro-explosion can be flexibly adjusted by controlling parameters such as the displacement speed, frequency of the movable member 23, and the time interval of the conduction of the electrode group 25 to adapt to different types and different oil contamination degrees of the devices 1 to be deoiled, improving the applicability and operation flexibility of the device. The device adopts the box body 3 structure, and the insulating liquid, the device 1 to be deoiled, and the electro-explosion device 2 are all accommodated in the cavity 31. This closed design can effectively prevent the splashes, shock waves, etc. that may be generated during the electro-explosion process from causing harm to the operators, and at the same time reduce the interference of external factors on the oil removal process, improving the safety of the operation.

[0039] Specifically, a high-voltage pulse power supply for vaporizing the metal wire 21, a central control system for monitoring the electro-explosion process, and a sensor module for monitoring the electro-explosion process and adjusting parameters (such as voltage, current, and shock wave intensity) are installed inside the fixing member 22; an operating platform for fixing the oil-removing device 1 is further provided inside the cavity 31 to prevent the shock wave generated by the electro-explosion from washing away the oil-removing device 1.

[0040] In one embodiment, the metal wire 21 is made of aluminum wire with a diameter of 0.1 mm, and the voltage of the pulse power supply is 5 kV. In an insulating liquid medium (deionized water), shock waves are generated by the electro-explosion of the metal wire 21 and act on the surface of the waste transformer core, successfully removing more than 90% of the waste oil, and the surface of the core is not damaged. Specifically, the metal wire 21 can also be made of one of copper wire, tungsten wire, and nickel-chromium wire.

[0041] In another embodiment, by connecting multiple metal wires 21 in parallel, multi-point synchronous shock waves can be generated, and the efficiency is increased by more than 50%. The waste oil in the internal structure of an industrial waste transformer can be removed within 10 minutes, and the waste oil recovery rate reaches 95%. At the same time, there is no waste liquid or waste gas emission during the operation of the electro-explosion device 2.

[0042] In one embodiment, as Figure 2 shown, the movable member 23 rotates around the center of the fixing member 22, and the movable member 23 and the fixing member 22 are concentrically arranged.

[0043] Adopting the foregoing technical solution, the movable member 23 rotates around the center of the fixing member 22, so that during the rotation of the metal wire 21, electro-explosion can occur at different angles with the center of the fixing member 22 as the center. This can make the shock wave act more uniformly on the surface of the oil-removing device 1. Regardless of the shape of the device, the oil can be removed more comprehensively and uniformly, effectively avoiding the situation of incomplete local oil removal, and further improving the consistency and stability of the oil removal effect.

[0044] In yet another embodiment, as Figure 3 shown, the fixing member 22 includes a flat section 221 and a curved section 222. The movable member 23 is composed of multiple track plates 26, and the movable member 23 moves around the outer surfaces of the flat section 221 and the curved section 222 of the fixing member 22. The electrode group 25 is arranged on the flat section 221 of the fixing member 22.

[0045] Adopting the foregoing technical solution, by designing the fixing member 22 into a shape having a planar section 221 and a curved section 222, the electrode group 25 can be arranged on the planar section 221 of the fixing member 22, so that the clamping member 24 on the movable member 23 is electrically connected to the electrode group 25 when moving to the planar section 221, generating an electric explosion. The surface of the planar section 221 is relatively flat, which is conducive to forming a stable and reliable electrical contact between the electrode group 25 and the clamping member 24, ensuring the smooth progress of the electric explosion.

[0046] Further, the electrode group 25 is arranged on the side of the fixing member 22 facing the device 1 to be degreased.

[0047] Adopting the foregoing technical solution, the electrode group 25 is arranged on the side facing the device 1 to be degreased, so that the shock wave generated by the electric explosion of the metal wire 21 can propagate more directly towards the device 1 to be degreased. This can minimize the energy loss of the shock wave during propagation, enable the shock wave to act on the surface of the device 1 to be degreased with stronger energy, more effectively strip the oil stain, thereby improving the degreasing efficiency and shortening the degreasing time. Since the shock wave can act more directly on the device 1 to be degreased, for some stubborn oil stains and oil stains on the surface of complex structures, it can more powerfully impact and destroy the adhesion between the oil stain and the device surface, ensuring that the oil stain is more thoroughly removed, further improving the degreasing effect, and ensuring that the surface of the device 1 to be degreased reaches a higher cleanliness.

[0048] Further, it further includes a wire supply mechanism 4, and the wire supply mechanism 4 is arranged outside the box body 3.

[0049] Adopting the foregoing technical solution, the wire supply mechanism 4 is arranged outside the box body 3, so that the operator does not need to open the box body 3 when replacing or replenishing the metal wire 21, and can directly operate outside. This greatly simplifies the replacement process of the metal wire 21, saves the operation time, and improves the work efficiency. Especially in continuous degreasing operations, the metal wire 21 can be quickly and conveniently replenished for the device, ensuring the continuity of the degreasing work and avoiding the downtime waiting time caused by the shortage of the metal wire 21. And the wire supply mechanism 4 can also be protected from being affected by the electric explosion in the box body 3, protecting the safety of the wire supply mechanism 4.

[0050] Specifically, the wire supply mechanism 4 can be as Figure 1 shown on the outer side of the horizontal plane of the box body 3, or can be arranged above or below the box body 3, so that the metal wire 21 supplies wire to the clamping member 24 in a spiral descending or ascending form.

[0051] Further, the cavity 31 includes a first chamber 32 for accommodating the oil-removing device 1 to be treated and a second chamber 33 for accommodating the electro-explosion device 2. The first chamber 32 and the second chamber 33 are connected through a guiding channel 34. A waste oil collection tank 5 for recovering waste oil and a separating device for separating waste oil are provided in the second chamber 33.

[0052] With the foregoing technical solution, in the first chamber 32, the oil-removing device 1 to be treated can be placed more stably without being interfered by the operation of the electro-explosion device 2. The second chamber 33 is specifically used for the installation and operation of the electro-explosion device 2, making the electro-explosion process more stable and reliable. The two chambers are connected through the guiding channel 34, ensuring that the shock wave can effectively be transmitted from the second chamber 33 to the first chamber 32 and act on the oil-removing device 1 to be treated, improving the oil-removing efficiency and ensuring the oil-removing quality. The waste oil collection tank 5 is arranged in the second chamber 33, capable of timely collecting the waste oil peeled off from the oil-removing device 1 to be treated and flowing in through the guiding channel 34.

[0053] Specifically, the separating device is one of a gravity settling separator, a filtration separator, a centrifugal separator, and a coalescing separator.

[0054] It can be understood that a guiding pipe can also be used instead of the guiding channel 34 to guide the shock wave in the insulating liquid to the position of the waste oil-removing device.

[0055] Further, a plurality of clamping members 24 are arranged at intervals in the up-and-down direction on the movable member 23, so that the plurality of clamping members 24 spaced up and down clamp a plurality of metal wires 21 spaced up and down to generate shock waves distributed up and down for oil-removing operations.

[0056] With the foregoing technical solution, the plurality of clamping members 24 spaced up and down can clamp the plurality of metal wires 21 spaced up and down, generating shock waves distributed up and down during electro-explosion. This enables each part of the oil-removing device 1 to be treated to be affected by the shock wave in the vertical direction. Especially for some devices with a certain height or thickness, the oil on their surfaces can be more comprehensively removed, avoiding the problem of incomplete oil removal caused by the limited action range of the shock wave, and greatly improving the comprehensiveness and uniformity of the oil-removing effect. The plurality of metal wires 21 generate electro-explosion simultaneously, forming multiple shock wave sources. Compared with the shock wave generated by a single metal wire 21, a greater impact force can be generated on the oil stain in a shorter time, accelerating the peeling speed of the oil stain. More oil stains can be processed in one oil-removing operation, reducing the time required for oil removal and improving the efficiency of the entire oil-removing operation.

[0057] In addition to the above preferred embodiments, the present application has other implementation manners. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope claimed by the present application.
