[0010] Furthermore, in this invention, the connecting member is a tubular structure, and the electrode conduit has a connection port for connecting with the connecting member, and the connecting member and the electrode conduit are connected in a sealed manner.
[0011] Furthermore, the electrode conduit is provided with a quick-release connector at its connection port for connection with the connecting member.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] The core of this invention is to provide a low-temperature ignition electrode device, which reduces the amount of water vapor in contact with the ignition electrode, thereby preventing water vapor condensation and improving the re-ignition success rate of the ignition electrode at low temperatures.
[0026] Please refer to Figure 1 A low-temperature ignition electrode device includes an electrode conduit 1 and a connecting member 3. An electrode 2 is disposed inside the electrode conduit 1, and one end of the electrode 2 extends out of the electrode conduit 1. The connecting member 3 includes at least two openings. One opening of the connecting member 3 is connected to the electrode conduit 1, and the other opening of the connecting member 3 is connected to a gas source for making the electrode conduit 1 under positive pressure.
[0027] It should be noted that the motor in this embodiment of the invention may be made of nickel-based alloy.
[0028] In addition, the electrode conduit 1 in this embodiment of the present invention may be made of high-purity alumina ceramic material.
[0029] Optionally, in some embodiments, the connecting member 3 and the electrode conduit 1 are sealed together. Specifically, the sealed connection can be achieved by threaded engagement or by integral molding.
[0030] Optionally, in some embodiments, the gas source may be clean air, supplied by equipment such as an air pump or an air tank, or other gases such as nitrogen.
[0031] Optionally, in some embodiments, a filter device is provided between the gas source and the connecting member 3 to filter the gas entering the electrode conduit 1 and reduce the impact of impurities on the electrode 2.
[0032] In the above embodiments, the filter device has a drying function, which can dry the moisture in the gas and reduce the influence of external gas on the electrode conduit 1.
[0033] In the above embodiments, the filtration device includes a filtration chamber. When the gas source passes through the filtration device, it passes through the filtration chamber. The filtration chamber is filled with anhydrous calcium chloride, and the anhydrous calcium chloride has a honeycomb structure to increase the drying effect on the moisture in the gas.
[0034] In use, electrode 2 is placed inside electrode conduit 1, with one end of electrode 2 extending out of electrode conduit 1 for ignition. Electrode conduit 1 is provided with a connecting member 3, which includes at least two openings. One opening of connecting member 3 is connected to electrode conduit 1, and the other opening of connecting member 3 is connected to a gas source for maintaining a positive pressure state inside electrode conduit 1. Therefore, when electrode 2 fails to ignite for the first time, an external gas source is introduced into electrode conduit 1 through connecting member 3, so that electrode conduit 1 is under positive pressure. This not only protects electrode 2 but also effectively prevents water vapor from condensing into water droplets or freezing on the inner wall of the conduit and the surface of electrode 2, thereby greatly improving the success rate of secondary ignition of electrode 2. The structure is simple and easy to install, with low cost, and can adapt to different working environments and needs.
[0035] Optionally, in some embodiments, the end of electrode 2 near its extension into electrode conduit 1 is fitted with electrode conduit 1 with a gap. The gap fit allows the non-dry gas in electrode conduit 1 to be discharged through the continuous supply of gas source when positive pressure is maintained in electrode conduit 1, which is more conducive to reducing the re-ignition of electrode 2.
[0036] In other embodiments, the end of electrode 2 extending out of electrode conduit 1 is connected in a sealed manner with electrode conduit 1, thereby reducing the entry of external gases with high humidity into electrode conduit 1.
[0037] Optionally, in some embodiments, to allow the electrode 2 to be sealed to the electrode conduit 1 at one end, the electrode conduit 1 is provided with a sealing element. This sealing element is annular and is coaxially mounted with the electrode 2. The inner diameter of the sealing element is adjustable so that its diameter can be changed as needed. When the inner diameter of the sealing element is reduced, the inner diameter sidewall of the sealing element is in sealed contact with the electrode 2. When the inner diameter of the sealing element is increased, the inner diameter sidewall of the sealing element can be in clearance fit with the electrode 2.
[0038] In the above embodiments, the seal is a hollow structure with flexible deformation function. The inner diameter of the seal is controlled by the air filled inside it, thereby enabling the seal to contact or gap fit with the electrode 2.
[0039] In the above embodiment, the seal is provided with an opening, and a fixing ring is provided on the outside of the seal. The fixing ring is fixedly connected to the electrode conduit 1. The fixing ring is used to fix the outer diameter of the seal and fix the position of the fixing ring.
[0040] In the above embodiment, the opening of the seal is connected to the air pump through a pipe, and the pipe is equipped with a one-way valve and a three-way valve. The one-way valve is located between the air pump and the three-way valve, and the other port of the three-way valve is connected to the outside. When the inner diameter of the seal needs to be increased, the three-way valve opens to discharge the high-pressure gas inside the seal. By adopting the above structure, the fit between the electrode guide tube 1 and the electrode 2 can be rotated quickly, which ensures the required sealing performance on the one hand, and also ensures the clearance fit when it is necessary to discharge the internal high humidity air on the other hand.
[0041] Optionally, in some embodiments, the connecting member 3 is a tubular structure, and the electrode conduit 1 has a connection port for connecting with the connecting member 3. The connecting member 3 and the electrode conduit 1 are connected in a sealed manner. That is, the tubular connecting member 3 is used to achieve communication with the electrode conduit 1, and the connection position is sealed.
[0042] In the above embodiments, the tubular connecting member 3 refers to a straight pipe structure. First, a connection port is opened on the electrode conduit 1, and the connecting member 3 is inserted into the connection port to achieve communication between the connecting member 3 and the electrode conduit 1.
[0043] Optionally, in some embodiments, the electrode conduit 1 can be tapped at the connection port to create a threaded structure, and a connector with a threaded structure that mates with the connection port can be fitted onto the connecting member 3 at the position where it mates with the connection port, thereby achieving a quick connection and seal between the connecting member 3 and the connection port.
[0044] Optionally, in some embodiments, a quick-release connector is provided at the connection port of the electrode conduit 1 for connecting with the connecting member 3. The quick-release connector also facilitates the rapid disassembly of the connecting member 3 and the electrode conduit 1.
[0045] Please refer to Figure 1 In some embodiments, the connecting member 3 is a three-way pipe, which is connected in series with the electrode conduit 1 through two of its openings, and the other opening of the three-way pipe is connected to a gas source for making the electrode conduit 1 under positive pressure. In other words, the connecting member 3 is a three-way pipe, which is beneficial for its connection with the electrode conduit 1.
[0046] Optionally, in some embodiments, the tee is an internal thread tee, and a threaded connection is used between the electrode conduit 1 and the tee.
[0047] Optionally, in some embodiments, a quick-release connector is provided on the pipe between the tee and the gas source to facilitate quick disconnection between the connecting member 3 and the gas source.
[0048] Optionally, in some embodiments, the connecting member 3 is provided with a valve for controlling the on / off state of the connecting member 3. By setting the valve, it is convenient to control the on / off state between the gas source and the electrode conduit 1, thereby facilitating the adjustment of the gas source on / off state as needed and reducing the waste of gas source.
[0049] Alternatively, in some embodiments, the valve may be of any structure, requiring only that it controls the opening and closing of the gas source and the electrode conduit 1.
[0050] Optionally, in some embodiments, the valve is an electromagnetic ball valve, which has the advantages of fast response, simple structure, low cost, and easy installation and maintenance.
[0051] Optionally, in some embodiments, the electrode conduit 1 is equipped with a pressure sensor 4 for detecting the pressure inside the electrode conduit 1. That is, by detecting the air pressure inside the electrode conduit 1 through the pressure sensor 4, the situation of excessive air pressure inside the electrode conduit 1 can be effectively avoided, thus preventing damage to the electrode conduit 1.
[0052] In the above embodiments, the pressure sensor 4 can be a sensor type with a display function, which also makes it convenient for users to observe the air pressure in the electrode conduit 1 in a timely manner.
[0053] Optionally, in some embodiments, the electrode conduit 1 is equipped with a temperature sensor 5 and a humidity sensor 6 for detecting the inside of the electrode conduit 1. That is, by detecting the humidity and temperature inside the electrode conduit 1 through the temperature sensor 5 and the humidity sensor 6, the user can easily understand the humidity situation inside the electrode conduit 1 and thus control the air intake of the gas source.
[0054] Optionally, in some embodiments, a controller is also included. The controller is electrically connected to the solenoid ball valve, pressure sensor 4, temperature sensor 5, and humidity sensor 6. That is, the controller is used to uniformly manage and control the solenoid ball valve, pressure sensor 4, temperature sensor 5, and humidity sensor 6. The control method is as follows: when the controller receives a failure of the electrode 2 to ignite for the first time, the controller controls the solenoid ball valve to open, thereby supplying gas to the electrode conduit 1 to maintain a certain positive pressure in the electrode conduit 1. After ignition is completed, the controller controls the solenoid ball valve to close.
[0055] Optionally, in some embodiments, the controller includes a control board (PLC board) and a housing, and the controller can be directly mounted on the electrode conduit and fixed by bolts or welding.
[0056] Optionally, in some embodiments, the pressure sensor may be a fiber optic sensor that is resistant to high temperatures (>300°C), inherently EMI-resistant, and can be made very small (diameter <0.5mm), and can be directly embedded in the sidewall of the electrode conduit.
[0057] Optionally, in some embodiments, the temperature sensor may employ a thermocouple (especially type K) that is heat-resistant (up to 1300°C), robust, fast-responding, and has strong EMI resistance (generating a millivolt-level voltage signal). It can be made into an extremely fine armored wire (diameter <1.0 mm) and embedded in the sidewall of the electrode conduit.
[0058] In other embodiments, only the temperature inside the electrode conduit may be detected, without detecting the pressure and humidity inside the electrode conduit.
[0059] In other words, the key point of this utility model is that: the electrode 2 is placed inside the electrode conduit 1, and one end of the electrode 2 extends out of the electrode conduit 1 to facilitate ignition. The electrode conduit 1 is provided with a connecting member 3, which includes at least two openings. One opening of the connecting member 3 is connected to the electrode conduit 1, and the other opening of the connecting member 3 is connected to a gas source for maintaining a positive pressure state inside the electrode conduit 1. Therefore, when the electrode 2 fails to ignite for the first time, the external gas source is introduced into the electrode conduit 1 through the connecting member 3, so that the electrode conduit 1 is under positive pressure. This not only protects the electrode 2, but also effectively prevents water vapor from condensing into water droplets or freezing on the inner wall of the conduit and the surface of the electrode 2, thereby greatly improving the success rate of secondary ignition of the electrode 2. The structure is simple and easy to install, with low cost, and can adapt to different working environments and needs.
