Technical Field

[0001] This disclosure pertains to the field of plasma discharge, specifically relating to a high-voltage arc ignition control device for a plasma torch. Background Technology

[0002] During the process of arc ignition using high voltage, the changes in the electric arc reflect the effect of arc ignition. The electric arc is generated by the electrode rod under the excitation of the high voltage electric field. The rotation speed of the electrode rod affects the effect of arc ignition. In the process of controlling high voltage arc ignition, the electrode rod control device mainly rotates at a constant speed and cannot adjust the speed to achieve the adjustment of the electrode rod rotation speed.

[0023] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0024] This combination Figures 1 to 4This document describes an embodiment of a high-voltage arc ignition control device for a plasma torch. Specifically, this high-voltage arc ignition control device for a plasma torch is constructed as a split structure, comprising a gear ring 103, a second gear 105, and a first gear 104. By moving the second gear 105 and meshing with the first gear 104, the rotational speed of the gear ring 103 is controlled, thereby adjusting the rotational speed of the electrode rod 3, controlling the change in the electric arc of the device, and achieving the effect of controlling arc ignition.

[0025] Please refer to Figures 1 to 4 A high-voltage arc ignition control device for a plasma torch includes: a motor 1, a rotating shaft 101 fixedly connected to the output end of the motor 1, a connecting rod 102 fixedly connected to the upper end of the rotating shaft 101, a gear ring 103 fixedly connected to the other end of the connecting rod 102, two gears 104 meshing at the root of the gear ring 103, a gear 105 meshing between the gears 104, the gear 105 slidably connected to the rotating shaft 101, and a rotating block 106 disposed directly below the gear 105, the rotating block 106 being threadedly connected to the rotating shaft 101.

[0026] The gear ring 103 is fixedly connected to the motor rod 3 via the connecting rod 102. The inner ring of the gear ring 103 is meshed with a gear 104. The rotation speed of the gear ring 103 reflects the rotation speed of the motor rod 3. By adjusting the rotation speed of the gear ring 103, the arc ignition device can be controlled, that is, the rotation speed reflects the frequency of arc ignition.

[0027] Gear 2 105 achieves speed change of gear ring 103 by meshing and disengaging with gear 1 104. When gear 2 105 meshes with gear 1 104, the rotational speed of gear ring 103 is slower than when gear 2 105 disengages from gear 1 104.

[0028] When controlling the arc-initiating device, the rotation speed of the electrode rod 3 can be controlled. To control the rotation speed of the electrode rod 3, first turn on the motor 1. The motor output drives the rotating shaft 101 to rotate, and the rotating shaft 101 drives the gear ring 103 to rotate. At this time, the gear 105 and the gear 104 are in a meshing state. The rotation of the gear ring 103 drives the electrode rod 3 to rotate, thus realizing arc initiation. At this time, the rotation speed of the gear ring 103 is slower than the rotation speed of the rotating shaft 101. If arc initiation control is to be performed, the rotation speed of the gear ring 103 can be adjusted to adjust the rotation speed of the electrode rod 3. When adjusting the gear ring 3, the rotating block 106 threadedly connected to the rotating shaft 101 can be rotated to lift the gear 105 slidably connected to the rotating shaft 101 upward, so that it disengages from the gear 104. At this time, the rotation speed of the rotating shaft 101 is the rotation speed of the gear ring 103.

[0029] A support rod 2 is fixedly connected to the upper end of the rotating shaft 101, and a hydrocyclone 201 is wrapped around the outer surface of the support rod 2.

[0030] The cyclone separator 201, which is wrapped around the outer surface of the support rod 2, forms a swirling airflow between the electrode rod 3 and the sleeve 4 after the airflow passes through the cyclone separator 201.

[0031] An electrode rod 3 is fixedly connected to the upper end of the support rod 2. The electrode rod 3 tapers from the lower end to the upper end into a cone shape. The motor rod 3 fixed to the upper end of the support rod 2 is used for arc ignition. During arc ignition, the motor rod 3 rotates to generate a low-current AC arc discharge. The cone-shaped motor rod 3 enables the device to perform arc discharge and thus ignite the arc.

[0032] The electrode rod 3 is rotatably connected to the inner wall of the sleeve 4. The sleeve 4 is connected to the gas supply pipe 401, and the other end of the gas supply pipe 401 is connected to the gas storage chamber 402.

[0033] The gas supply device connected to sleeve 4 can ensure that the internal gas pressure remains balanced so as to obtain low-temperature non-equilibrium plasma under atmospheric pressure. During the arc ignition process, the gas pressure inside sleeve 4 will change. The gas supply device will dynamically detect and adjust according to the changes in internal gas pressure to achieve stable pressure regulation.

[0034] The outer wall of the sleeve 4 is fixedly connected to one end of the wire 5, and the wire 5 is fixedly connected to the plasma power supply 501. A grounding wire 7 is fixedly connected to the lower surface of the electrode rod 3.

[0035] The outer wall of the sleeve 4 is fixed with a wire 5 and connected to a plasma power supply 501 to energize the motor rod 3. The grounding wire 7 is set to prevent electrostatic induction electric shock from nearby charged objects and ensure the safety of the circuit.

[0036] The rotating shaft 101 is divided into upper and lower parts. The upper part is slidably connected to the gear 105, and the thread on the outer wall of the lower part is threadedly connected to the rotating block 106.

[0037] The rotating shaft 101 is divided into two parts for moving the second gear 105. During the speed change process, the position of the second gear 105 can be changed. Since the lower part of the rotating shaft 101 is threadedly connected to the rotating block 106 and the upper part is slidably connected to the second gear 105, when the rotating block 106 rotates upward, the second gear 105 that it is in contact with slides upward and disengages from the first gear 104, thus realizing the speed change.

[0038] A support rod 8 is rotatably connected to the bearing of gear 104. The lower end of the support rod 8 is slidably connected to the inner wall of the groove of turntable 801. Turntable 801 is located directly below motor 1.

[0039] A turntable 801 is provided directly below the motor 1 to provide support for the second support rod 8 and the gear 104 connected thereto. At the same time, during rotation, the groove on its surface facilitates the revolution of the gear 104. The revolution trajectory of the gear 104 during rotation is the trajectory of the groove opened on the turntable 801.
