Description

Technical Field

[0001] This utility model relates to the field of fire sensing technology for combustion equipment, and in particular to a bipolar ignition sensing device with a liquid collection tank for combustion equipment. Background Technology

[0002] The fuels used in combustion equipment have always been natural gas, liquefied petroleum gas, diesel, or gasoline. Without exception, water vapor will evaporate during the combustion process of these fuels. When too much water vapor evaporates, water droplets will drip onto the ceramic insulator of the ignition device. At the same time, some carbon deposits will also adhere to the electrode needle and the ceramic insulator. Over time, more and more carbon will accumulate. Now, due to the problems of liquid and carbon deposits, the head of the ceramic insulator has also become a conductor. The electric spark will start to ignite at the junction of the ceramic insulator and the electrode needle, causing the combustion equipment to malfunction and alarm and fail to work properly. Utility Model Content

[0003] The purpose of this invention is to solve the problem mentioned in the background art where liquid and carbon deposits are located on the ceramic insulator, causing the head of the ceramic insulator to also become a conductor.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A bipolar ignition induction device with a liquid collection tank for combustion equipment includes a metal support plate, two electrode needles, a ceramic insulator, and a wire connection end. The metal support plate has several mounting holes for mounting on the combustion equipment. The two electrode needles are symmetrically arranged, with their tips used to release electric sparks. The ceramic insulator is sleeved in the middle of the electrode needles, with a recessed groove on its upper end face and at least one annular groove on its outer surface. The wire connection end is electrically connected to the two electrode needles respectively, and the wire connection end is used to transmit voltage to the electrode needles in conjunction with the wire assembly.

[0006] Preferably, the upper end face of the ceramic insulator is chamfered.

[0007] Preferably, the annular groove is distributed on the upper side of the metal support plate.

[0008] Preferably, the upper portions of the two electrode needles gradually approach each other.

[0009] Preferably, the ceramic insulator is made of a high-temperature resistant insulating material, and its length covers 1 / 2 to 2 / 3 of the non-discharge area in the middle of the electrode needle.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] The recessed groove on the upper end face of the ceramic insulator can guide the water droplets generated by combustion into the groove, preventing liquid from accumulating on the end face and forming a conductive path; the annular groove on the outer surface intercepts the accumulated liquid and carbon deposits flowing down the surface, reducing their accumulation at the junction of the electrode needle and the ceramic insulator, ensuring that the ceramic insulator always maintains good insulation performance, preventing electric sparks from igniting in non-top areas, and fundamentally solving the problem of malfunctions caused by contamination in traditional ignition devices.

[0012] The ignition spacing of the electrode needles has been adjusted before leaving the factory, so operators do not need to adjust it again. It can be used directly after installation, which shortens the installation time. This device is easy to use, can improve the service life of combustion equipment, increase the number of effective ignitions, and reduce the number of fault alarms of combustion equipment.

[0021] Please see Figure 1-2 A bipolar ignition induction device with a liquid collection tank for combustion equipment includes a metal support plate 1, two electrode needles 3, a ceramic insulator 2 and a wire connection end 4. The metal support plate 1 has several mounting holes for installation on the combustion equipment. The metal support plate 1 is flat and made of high-temperature resistant metal such as stainless steel. There are two mounting holes for fixing the device to the combustion equipment by screws or bolts.

[0022] Two electrode needles 3 are symmetrically arranged, with the tips used to release electric sparks. The two electrode needles 3 are used for double-needle ignition. The upper parts of the two electrode needles 3 gradually approach each other to form a tip discharge structure, with the tips used to release electric sparks to ignite the fuel.

[0023] A ceramic insulator 2 is fitted onto the middle of the electrode needle 3. A groove 5 is provided on the upper end face of the ceramic insulator 2, allowing some water vapor to flow into the groove 5, so that the water vapor will not remain on the end face of the ceramic insulator 2. One ceramic insulator 2 is fitted onto one electrode needle 3. A chamfer 6 is provided on the upper end face of the ceramic insulator 2. The chamfer 6 structure increases the insulation distance between two ceramic insulators 2. At least one annular groove 7 is provided on the outer surface of the ceramic insulator 2. The annular groove 7 is recessed inward and is used to collect water vapor and carbon deposits or dust generated by fuel combustion.

[0024] The annular groove 7 is distributed on the upper side of the metal support plate 1, so that the annular groove 7 is located in the combustion chamber. The ceramic insulator 2 is made of high temperature resistant insulating material, and its length covers 1 / 2-2 / 3 of the non-discharge area in the middle of the electrode needle 3. The annular groove 7 effectively intercepts the liquid and carbon deposits flowing down the surface of the ceramic insulator 2, and increases the distance between the two ceramic insulators 2, so that the ignition device can work normally.

[0025] There are two wire connection ends 4, which are electrically connected to the two electrode needles 3 respectively. The wire connection ends 4 are located at the bottom of the electrode needles 3 and are used to transmit voltage to the electrode needles 3 in conjunction with the wire assembly.

[0026] Align the metal support plate 1 of this device with the positioning groove of the combustion equipment, so that the tip of the electrode needle 3 faces the gas outlet. Secure it with screws or bolts through the mounting holes, and connect the wire assembly to the wire connection terminals 4 of the two electrode needles respectively to complete the circuit conduction.

[0027] When the combustion equipment is started, the wire assembly transmits voltage to the electrode needle 3 through the wire connection terminal 4, and the tip of the electrode needle 3 releases an electric spark to ignite the fuel. When the water vapor and carbon deposits generated during combustion come into contact with the ceramic insulator 2, the recessed groove 5 on the upper end face guides the accumulated liquid into the groove, and the annular groove 7 on the outer surface intercepts and collects the remaining accumulated liquid and carbon deposits, preventing them from accumulating on the end face or surface to form a conductor, ensuring the insulation performance of the ceramic insulator 2, preventing unexpected sparking, and reducing fault alarms.

[0028] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
