Description

Technical Field

[0001] The present invention relates to a burner ignition gun, and more particularly to a natural gas burner ignition gun with a magnetic coupling joint. Background Art

[0002] There are a large number of industrial boilers in our country. With the gradual elimination of small coal-fired boilers, gas and oil-fired industrial boilers have become the main force of industrial boilers. The natural gas burners supporting industrial boilers usually have the ability of multi-stage firepower adjustment to meet the wide load requirements. The gas burner adopts a fixed design and is installed on the furnace. Considering the uniform heating of the four sides of the furnace, the burner is inserted deeper into the furnace, so the ignition cable is also arranged longer.

[0003] Since the ignition cable is made of rubber, under high load, the temperature in the furnace is relatively high, and the ignition cable cannot be pulled out. It is baked by high temperature and finally burned out. After the ignition cable is burned out, the gas burner cannot be ignited and the boiler cannot be started, which affects industrial production. Summary of the Invention

[0004] The purpose of the present invention is to overcome the above-mentioned disadvantages of the prior art, and provide a natural gas burner ignition gun with a magnetic coupling joint, which can effectively avoid the burning of the ignition cable.

[0005] To achieve the above purpose, the natural gas burner ignition gun with a magnetic coupling joint of the present invention includes magnetic male and female joints, an aluminum cylinder, an ignition gun barrel, a discharge electrode, an ignition gun head, an ignition cable, an ignition transformer, a wire rod and a winding motor;

[0006] The magnetic male and female joints include a male joint and a female joint. Among them, the male joint is located inside the aluminum cylinder, the upper end of the female joint is inserted into the aluminum cylinder, the outer wall of the aluminum cylinder is fixed to the outer wall of the ignition gun barrel, the upper end of the female joint faces the lower end of the male joint, one end of the discharge electrode is electrically connected to the female joint, the other end of the discharge electrode faces the ignition gun head, one end of the ignition cable is connected to the output end of the ignition transformer, the other end of the ignition cable is inserted into the aluminum cylinder after passing around a pulley and is connected to the male joint, the middle part of the ignition cable is wound around the wire rod, and the output shaft of the winding motor is connected to the wire rod.

[0007] The upper end of the ceramic insulating tube is fixed to the lower end of the female joint, and the end of the discharge electrode passes through the ceramic insulating tube and is electrically connected to the female joint.

[0008] The end of the ignition cable is inserted into the aluminum cylinder after passing around a pulley and is connected to the male joint.

[0009] It further includes a remote control system, wherein the remote control system is connected to the winding motor and the ignition voltage transformer.

[0010] A ceramic insulating sleeve is provided on the outside of the magnetic male and female joints.

[0011] A power switch is provided between the ignition transformer and the external power supply.

[0012] When ignition is required, the winding motor rotates forward to release the ignition cable. Under the action of the magnetic male-female connector and the self-weight of the ignition cable, the ignition cable descends along the aluminum cylinder, and finally the male connector in the magnetic male-female connector contacts and engages with the female connector to conduct electricity. Subsequently, the ignition transformer is started to generate an electric arc at the discharge electrode. When natural gas is introduced into the ignition gun barrel, the electric arc ignites the natural gas emitted at the ignition gun head to form a flame.

[0013] When the flame is stable, the winding motor rotates in reverse, and the male connector and the female connector in the magnetic male-female connector are separated by the pulling force of the ignition cable. The ignition cable loses its power-on ability, and the ignition cable is slowly retracted by the wire rod and finally completely withdrawn from the furnace.

[0014] The present invention has the following beneficial effects:

[0015] When the natural gas burner ignition gun with a magnetic absorption type connector of the present invention is specifically operated, conduction is achieved by docking the magnetic male-female connectors. During use, after successful ignition, when it is confirmed that the fire is stable, the winding motor rotates in reverse, and the male connector and the female connector in the magnetic male-female connector are separated by the pulling force of the ignition cable. The ignition cable loses its power-on ability, and the ignition cable is retracted by the wire rod and finally completely withdrawn from the furnace, thoroughly solving the problem of cable burnout caused by high temperature in the furnace, with high safety, improving the reliability and service life of the equipment, low cost, reliable principle, high degree of automation, and having important practical value.

[0019] The structural schematic diagrams according to the disclosed embodiments of the present invention are shown in the accompanying drawings. These figures are not drawn to scale, and for the purpose of clear expression, some details are enlarged and some details may be omitted. The shapes of various regions and layers shown in the figures and their relative sizes and positional relationships are only exemplary. In practice, there may be deviations due to manufacturing tolerances or technical limitations, and those skilled in the art can design regions / layers with different shapes, sizes, and relative positions according to actual needs.

[0020] Reference Figure 1 , the electrode 1 for igniting the natural gas burner with a magnetic snap connector according to the present invention includes an ignition gun head 2, a ceramic insulating tube 3, a magnetic male-female connector 4, an ignition gun barrel 6, an aluminum cylinder 7, a winding motor 8, a pulley 9, an ignition cable 10, a wire rod 11, and an ignition transformer 12;

[0021] The magnetic male-female connector 4 includes a male connector and a female connector. Among them, the male connector is located inside the aluminum cylinder 7, the upper end of the female connector is inserted into the aluminum cylinder 7, the outer wall of the aluminum cylinder 7 is fixed to the outer wall of the ignition gun barrel 6, the upper end of the ceramic insulating tube 3 is fixed to the lower end of the female connector, the upper end of the female connector faces the lower end of the male connector, one end of the electrode 1 passes through the ceramic insulating tube 3 and is electrically connected to the female connector, the other end of the electrode 1 faces the ignition gun head 2, one end of the ignition cable 10 is connected to the output end of the ignition transformer 12, the other end of the ignition cable 10 bypasses the pulley 9 and then is inserted into the aluminum cylinder 7 and connected to the male connector, the middle part of the ignition cable 10 is wound around the wire rod 11, and the output shaft of the winding motor 8 is connected to the wire rod 11.

[0022] The aluminum cylinder 7 serves as the track for the ignition cable 10 and the magnetic male-female connector 4, ensuring that when the ignition cable 10 enters, the magnetic male-female connector 4 can accurately attract and mate, ensuring full contact between the metal contacts 5 of the magnetic male-female connector 4. At the same time, to avoid magnetic force interaction between the magnetic male-female connector 4 and the aluminum cylinder 7, an aluminum cylinder 7 that is non-magnetic and heat-resistant is selected as the track. A ceramic insulating sleeve is provided on the outside of the magnetic male-female connector 4. Under the guidance of the aluminum cylinder 7, the male and female connectors on the ignition cable 10 can accurately attract and mate, enabling the magnetic male-female connector 4 to be energized. The outside of the discharge electrode 1 is wrapped with a ceramic insulating tube 3, so that the discharge electrode 1 can only release an arc at the ignition gun head 2 and cannot discharge with the ignition gun barrel 6.

[0023] The ignition gun barrel 6 is made of stainless steel and is used to convey natural gas to the ignition gun head 2. The pulley 9 is used to guide and deflect the ignition cable 10. The winding motor 8 is connected to the remote control system. The operator can control the forward and reverse rotation of the winding motor 8 from a distance, thereby controlling the release or retraction of the ignition cable 10 by the wire rod 11. The ignition cable 10 is connected to an external power supply through the ignition transformer 12 to supply power to the high-energy igniter.

[0024] The working process of the present invention is divided into a wire-receiving process and a wire-releasing process;

[0025] The wire-releasing process is as follows:

[0026] When the ignition gun is ready to ignite, the operator controls the winding motor 8 to rotate forward through the remote control system to release the ignition cable 10. Under the action of the magnetic male-female connector 4 and the self-weight of the ignition cable 10, the ignition cable 10 slowly descends along the aluminum cylinder 7 and finally makes the male and female connectors in the magnetic male-female connector contact and attract to conduct. Subsequently, the ignition transformer 12 is started, causing an arc to be generated at the discharge electrode 1. When natural gas is introduced into the ignition gun barrel 6, the arc ignites the natural gas emitted at the ignition gun head 2 to form a flame.

[0027] The wire-receiving process is as follows:

[0028] After successful ignition and confirmation of stable combustion, the operator controls the winding motor 8 to rotate in reverse through the remote control system, uses the pulling force of the ignition cable 10 to separate the male and female connectors in the magnetic male-female connector 4, the ignition cable 10 loses the ability to be energized, and the ignition cable 10 is slowly recovered by the wire rod 11 and finally completely withdraws from the furnace, completely solving the problem of cable burnout caused by high temperature in the furnace.
