Novel boiler ignition gun and machining method thereof

Abstract

The invention provides a novel boiler ignition gun and a machining method thereof. The novel boiler ignition gun comprises an ignition transformer part, an ignition gas pipe part, a combustion-supporting cooling air pipe part and a combustion part; fixing an inner sealing ring and an outer sealing ring of the ignition gas pipe is carried out by using a clamp spring, O-shaped rings are used for sealing the ignition gas pipe, and fixing and supporting the ignition gas pipe are carried out by using cooperation of a countersunk head screw and a ceramic ring, so that the function of the ignition gun is achieved; and the machining and manufacturing method of the ignition gun sequentially comprises the steps of machining the ignition gun cooling air pipe structure, determining the sizes of the inner sealing ring and the outer sealing ring of the ignition gas pipe, installing the inner sealing ring sealing O-shaped ring and the outer sealing ring sealing O-shaped ring, installing the inner sealing ring fixing clamp spring and the outer sealing ring fixing clamp spring, machining the ignition air pipe structure, machining the inner sealing ring structure and the outer sealing ring structure of the ignition gas pipe and installing the ignition transformer. According to the novel boiler ignition gun and the machining method thereof, the outer layer of the ignition gas pipe is the high-temperature-resistant insulating layer, the ignition gas pipe is installed in the inner part of a cooling air pipe in a penetrating mode, the use of the ignition gun is achieved, and the safe and reliable performance is improved.

Description

technical field [0001] The invention specifically relates to a novel boiler ignition gun and a processing method thereof. Background technique [0002] Porcelain tubes are generally used as the outer layer insulation of the ignition air pipe in the prior art, and sealants are used to seal between the ignition air pipe, the combustion-supporting cooling air pipe and the ignition transformer. In the actual use process, there are the following objective disadvantages: [0003] 1. The insulation performance is poor. When the ignition gas contains condensate or the humidity of the combustion air is too high, it is often difficult to ignite, causing the boiler to fail to ignite; [0004] 2. The fixing and support of the ignition air pipe adopt hollow ceramic rings with openings. The high-temperature vibration environment can easily cause damage to the ceramic rings. After the ignition air pipe loses support, the gap between the ignition air pipe and the outer combustion-supporting...

AI Technical Summary

Problems solved by technology

[0003] 1. The insulation performance is poor. When the ignition gas contains condensate or the humidity of the combustion air is too high, it is often difficult to ignite, causing the boiler to fail to ignite;

[0004] 2. The fixing and support of the ignition air pipe adopt hollow ceramic rings with openings. The high-temperature vibration environment can easily cause damage to the ceramic rings. After the ignition air pipe loses support, the gap between the ignition air pipe and the outer combustion-supporting cooling air pipe shrinks or even directly contacts due to its own weight. The arc is triggered in the middle of the ignition gun, causing the boiler to fail to ignite;

[0005] 3. The sealing between the ignition gas pipe, the combustion cooling air pipe and the ignition transformer is bonded with sealant, which is difficult to repair and disassemble. After the repair, it is necessary to wait for the sealant to dry and harden. The ignition gun is scrapped;

[0006] 4. The AC 220V power supply of the ignition transformer adopts the wiring method of wires, which is prone to poor contact, short circuit, open circuit, and outdoor installation is prone to faults such as water inflow and short circuit;

Generally, it is composed of the ignition gas pipe located in the center of the ignition gun, the insulating porcelain tube outside the ignition gas pipe, the hollow supporting fixed porcelain tube with holes, the combustion-supporting cooling air pipe that doubles as the outer tube of the ignition gun, the sealing part of the ignition gas pipe, the ignition transformer, and the ignition transformer. As the main components, the ignition transformer installation box, ignition gas, combustion-supporting cooling air connector, power supply wiring and other components are added.
