Internal -combustion engine heating device

一种内燃机加热装置

Abstract

The utility model discloses an internal -combustion engine heating device, including set up in explosion -proof heater plug in the internal -combustion engine, explosion -proof heater plug include with the cable of the interior utmost point capital portion rigid coupling in the explosion -proof heater plug, utmost point toe portion is connected with the heating wire, the utmost point post with cable outer wall parcel is equipped with explosion -proof casing, just explosion -proof casing bottom intercommunication is equipped with thermal -insulated shell, be equipped with the heating shell in the thermal -insulated shell, the heating shell will heating wire rigid coupling parcel, heating shell bottom is passed through thermal -insulated shell bottom extends to outside the thermal -insulated shell. Explosion -proof casing will the utmost point post with cable outer wall parcel, the heating shell will heating wire parcel, and the thermal -insulated shell upper portion parcel that will insulate against heat makes cable, utmost point post and heating wire and external isolation, fundamentally has got rid of the appearance in the source of lighting, and this just makes the internal -combustion engine work in comparatively dangerous region (containing inflammables such as explosive gases, dust).
本实用新型公开了一种内燃机加热装置,包括设置于所述内燃机内的防爆预热塞,所述防爆预热塞包括与所述防爆预热塞内的内极柱顶部固接的电缆,所述极柱底部与电热丝连接,所述极柱和所述电缆外壁包裹设有防爆壳体,且所述防爆壳体底部连通设有隔热外壳,所述隔热外壳内设有加热外壳,所述加热外壳将所述电热丝固接包裹,所述加热外壳底部通过所述隔热外壳底部延伸至所述隔热外壳外。所述防爆壳体将所述极柱和所述电缆外壁包裹,所述加热外壳将所述电热丝包裹,而隔热外壳又将隔热外壳上部包裹,使电缆、极柱和电热丝与外界隔离,从根本上去除了点燃源的出现,这就使内燃机可以在较为危险的区域(含有爆炸性气体、粉尘等易燃物)中工作。
