Description

Technical Field

[0001] The utility model relates to a combustion furnace igniter capable of preventing heat collection and blocking, and belongs to the field of combustion furnace ignition tools. Background Art

[0002] The igniters of existing combustion furnaces are mostly of the guide rail type, that is, the igniters are fixed on a horizontal reciprocating motion mechanism, and then the ignition is extended and retracted through the guide rail. During use, the applicant found that the existing igniters are prone to bending due to external force collisions during use. In this way, when extending and retracting, they are prone to getting stuck with the guide rail and hindering movement. At the same time, the existing igniters are easily affected by the ignition rod or the combustion furnace, and are prone to overheating, which seriously affects the service life of the igniter.

[0003] Therefore, there is a need for a combustion furnace igniter that can prevent heat accumulation and blocking, which is conducive to the stable use of the equipment. Utility Model Content

[0004] In view of this, the purpose of the present invention is to provide a combustion furnace igniter that can prevent heat collection and jamming, which can prevent heat collection and jamming and is conducive to the stable use of the equipment; and can overcome the shortcomings of the existing technology.

[0005] The purpose of this utility model is achieved through the following technical solutions:

[0006] The utility model discloses an igniter for a combustion furnace which can prevent heat collection and jamming. The igniter comprises an outer sleeve which is mounted on a horizontal reciprocating motion mechanism of the combustion furnace. A positioning inner tube is provided on the outer sleeve. A heat sink is fixed to one end of the positioning inner tube. A silicon nitride ignition rod connected to a power source is provided at the free end of the heat sink. The silicon nitride ignition rod is positioned and mounted at one end of the outer sleeve. A heat dissipation hole is provided on the outer sleeve.

[0007] As mentioned above, a positioning plate is provided at one end of the outer sleeve near the silicon nitride ignition rod, a probe hole for the silicon nitride ignition rod is provided on the positioning plate, the silicon nitride ignition rod is provided with an external thread, and positioning nuts for the silicon nitride ignition rod are provided on both the inner and outer sides of the positioning plate.

[0008] As mentioned above, a flange that cooperates with the positioning plate is provided on the outer sleeve, and the flange and the positioning plate are connected by bolts and nuts.

[0009] As mentioned above, the silicon nitride ignition rod is bound and connected to the heat sink or a mounting sleeve is provided at the connecting end of the silicon nitride ignition rod, and the mounting sleeve is fixed to the heat sink by welding.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] 1. The present invention can improve the heat dissipation capacity through the combination of heat sinks and heat dissipation holes, effectively preventing heat accumulation, which is beneficial to increasing the service life of the equipment. At the same time, the outer sleeve can protect the silicon nitride ignition rod inside it. Secondly, when the outer sleeve collides, it is mostly concave inward. At the same time, when there are heat dissipation holes, it is concave inward and is not likely to cause bulges on the outer wall. Therefore, when the entire device is moved, it is not likely to get stuck. In addition, the device is composed of multiple parts, including the outer sleeve, the positioning inner tube, the heat sink, and the silicon nitride ignition rod. The dimensions of each part are standardized, so that when a part is damaged, it is easy to replace it, reducing the maintenance cost of the equipment.
