Description
Technical Field
[0001] The utility model relates to the technical field of plasma, and particularly relates to a lightweight plasma torch anode. Background Art
[0002] Plasma technology is an advanced technology that utilizes the unique physical and chemical properties of plasma (the fourth state of matter) to achieve corresponding goals. It plays an increasingly important role in modern industry due to its high efficiency, cleanliness, and controllability. Plasma torches, as key equipment for generating plasma, their design and material selection play a decisive role in the efficiency and stability of the entire plasma system. However, traditional plasma torches are usually heavy due to complex structures and limitations in material selection, not only resulting in high production costs but also being difficult to maintain during long-term use.
[0003] Achieving the lightweight of plasma torch equipment can not only reduce the labor burden of operators but also enhance the mobility and reaction speed of the equipment. However, such a lightweight design must ensure that it does not affect the service life and reliability of the torch. As the anode, a key component of the plasma torch, its performance and durability directly affect the performance and economic benefits of the overall plasma generator. Therefore, developing an anode that is both lightweight and can ensure high life and high reliability is particularly important for improving the overall performance of plasma torches. Summary of the Utility Model
[0004] The purpose of the utility model is to overcome the above deficiencies of the prior art and provide a lightweight plasma torch anode, which has a lightweight structure, good heat dissipation, and a long service life.
[0005] The technical solution of the utility model is: a lightweight plasma torch anode, including a body, and an arc channel axially penetrating through the body is arranged inside the body; a positioning stop, a fixing thread, a first sealing ring groove, a water-cooled straight section, a water-cooled enhanced heat dissipation section, and a second sealing ring groove are sequentially arranged on the outer surface of the body from left to right; the arc channel is sequentially divided into an arc transition section, an arc compression section, a throat section, a diverging port, and a nozzle section from left to right; heat dissipation slots are arranged on the water-cooled enhanced heat dissipation section; the nozzle section and the water-cooled enhanced heat dissipation section are internally and externally corresponding on the body.
[0006] Furthermore, the positioning stop serves as the positioning reference surface of the anode, facilitating quick positioning during installation. A fixing thread is arranged on the right side of the positioning stop, used to fix the anode on the corresponding equipment and transmit current through the thread.
[0007] Furthermore, a transition inclined surface is arranged between the water-cooled straight section and the water-cooled enhanced heat dissipation section.
[0008] Further, the inclination angle of the transition inclined plane is adapted to the inclination angle of the expansion port. Preferably, the inclination angle of the transition inclined plane is the same as the inclination angle of the expansion port.
[0009] Further, the diameter of the arc transition section ranges from 30 to 45 mm.
[0010] Further, the arc compression section is single-segment or divided into multiple segments. Preferably, the arc compression section can be divided into two segments, and the arc compression section is used to further compress the arc through the action of the rotating air flow.
[0011] Further, the diameter of the throat section is the minimum of the arc channel diameter, and the diameter range is between 10 and 25 mm. Its function is to enhance the arc voltage. Immediately following the throat section is the expansion port, which plays a role in guiding the arc to spread outwards.
[0012] Further, the nozzle section is the landing point of the arc and also the final nozzle of the arc. It is the area with the highest anode temperature. The corresponding water-cooled enhanced heat dissipation section outside the nozzle section ensures good heat dissipation effect of the anode during operation.
[0013] Further, the nozzle section is single-segment or divided into multiple segments. Preferably, the nozzle section consists of two segments, which are the straight section and the inclined section in sequence from left to right, where the inclined section expands outwards; the nozzle section can also be a cavity with an expansion angle of α, and the range of the expansion angle α is between 0 and 15°.
[0014] Further, the direction of the heat dissipation slot is parallel to the axis of the body, and the heat dissipation slots are evenly distributed in a circle on the body. The heat dissipation slots are used to increase the heat dissipation area and improve the cooling efficiency. Of course, the direction of the heat dissipation slots can also form a certain angle with the axis, or it can be arc-shaped, such as circular arc-shaped or spiral-shaped, as long as the heat dissipation area can be increased, and any shape is not limited.
[0015] Further, a hook wrench hole is also provided on the right side of the second sealing ring groove, which is convenient for disassembly, installation and maintenance using special tools.
[0016] The beneficial effects of the present utility model compared with the prior art:
[0017] 1. The lightweight plasma torch anode of the present application adopts an integrated processing technology. The outer surface of the anode is cooled by cooling water to achieve rapid cooling of the entire anode, effectively taking away heat and extending the service life. The inner cavity of the anode is an arc channel, and the rotating compressed air flow compresses the arc in the channel to ensure the stability of the arc and generate high-quality plasma; the leftmost end of the anode is the anode surface, which can strike an arc with the cathode under high-frequency voltage, or strike an arc by quickly separating from the cathode after contact;
[0018] 2. The nozzle section of the anode in this application is the arc landing point, which is the area with the highest temperature of the anode. Therefore, a water-cooled enhanced heat dissipation section is correspondingly designed on the outer side of the nozzle section to ensure the heat dissipation effect of the anode during the entire working process.

[0025] Embodiment **********

[0027] In this embodiment, the positioning stop 1 serves as the positioning reference surface of the anode, facilitating quick positioning during installation. A fixing thread 2 is arranged on the right side of the positioning stop 1, which is used to fix the anode on the corresponding equipment and transmit current through the thread. After the fixing thread 2 is the second groove, which is used to install an O-ring to ensure the sealing between the anode and the equipment.
[0028] In this embodiment, a transition inclined surface is arranged between the water-cooled straight section 4 and the water-cooled enhanced heat dissipation section 5, and the inclination angle of the transition inclined surface is the same as that of the diverging section.
[0029] In this embodiment, the diameter range of the arc transition section 8 is between 30 - 45 mm. The arc compression section 9 is divided into two sections, namely a first compression section 91 and a second compression section 92. The arc compression section 9 is used to further compress the arc through the action of a rotating air flow.
[0030] In this embodiment, the diameter of the throat section 10 is the minimum of the arc channel diameter, and the diameter range is between 10 - 25 mm. Its function is to enhance the arc voltage. Immediately following the throat section 10 is the diverging section 11, which plays a role in guiding the arc to spread outwards.
[0031] In this embodiment, the nozzle section 12 is composed of two sections, namely a straight section 121 and an inclined section 122 arranged in sequence from left to right. The diameter of the straight section 121 remains the same, while the inclined section 122 expands outwards and the diameter gradually increases.
[0032] In this embodiment, the direction of the heat dissipation slot 51 is parallel to the axis of the body, and the heat dissipation slot 51 is evenly distributed in a circle on the body.
[0033] In this embodiment, similar to the first sealing ring groove 3, the second sealing ring groove 6 is also used to install an O-ring to ensure the sealing between the anode and the equipment. A hook wrench hole 7 is also arranged on the right side of the second sealing ring groove.
[0034] Working principle: When an arc is formed between the anode and the corresponding cathode in this application under the action of a high-frequency voltage or an arc is generated after contact and then quickly separated, the rotating compressed air flow enters the arc channel of the anode from the left end, making the arc stable and generating high-quality plasma. At the same time, cooling water circulates on the outer surface of the anode to take away a large amount of heat generated during the working process, thereby prolonging the service life of the anode.

[0037] The above are only some embodiments of the present utility model and are not used to limit the present utility model. For those skilled in the art, the present utility model can have combinations and variations of the foregoing various technical features. Without departing from the spirit and scope of the present utility model, improvements, variations, equivalent replacements of the present utility model, or the use of the structure or method of the present utility model in other fields to achieve the same effect all fall within the protection scope of the present utility model.
