The altar lamp that numerous domestic heating furnace is selected is non-explosion-proof because most project to burner without requirement of explosion proof, seldom have the Explosion-Proof of mechanism research altar lamp.And even if there is requirement, most of projects are also that critical piece is such as instrumentation, control valve etc. is selected explosion-proof.Because rare explosion-proof altar lamp can be for selecting, therefore there is systematic defect.Therefore, provide a kind of novel explosion-proof burner altar lamp, and in smooth combustion, adapt to the aspects such as heating furnace range of negative pressure is wider burner altar lamp carried out to revising of the functions, become current problem demanding prompt solution.
Utility model content
The purpose of this utility model is to provide a kind of explosion-proof burner altar lamp, to solve the explosion-proof of burner altar lamp and smooth combustion problem, makes the electrical connection of altar lamp outside heating furnace meet explosion-proof relevant criterion, reaches requirement of explosion proof; In addition, adopt the Venturi tube of new structure, altar lamp combustion gas and combustion air are fully mixed, burn more stable, to adapt to the wide in range combustion chamber draft requirement of different heating-furnace.
For reaching this object, the utility model by the following technical solutions:
An explosion-proof burner altar lamp, comprises lamp bracket kept burning day and night, is located at ignitor and flame sensor on lamp bracket kept burning day and night, and described ignitor outside is provided with electrode anti-explosion terminal box.
Further, described flame sensor outside is provided with sensor anti-explosion terminal box.
Further, described electrode anti-explosion terminal box inside has for spherical cavity, and is provided with opening at the two ends of described spherical cavity, and described opening is all connected with the mounting interface with cylindrical cavity; Described electrode anti-explosion terminal box is connected with described lamp bracket kept burning day and night by the mounting interface of one end, makes described electrode be positioned at described spherical cavity.
Further, described sensor anti-explosion terminal box inside has spherical cavity, and is provided with opening at the two ends of described spherical cavity, and described opening is all connected with the mounting interface with cylindrical cavity; Described sensor anti-explosion terminal box is connected with described lamp bracket kept burning day and night by the mounting interface of one end, makes described flame sensor be positioned at described spherical cavity.
Further, on described lamp bracket kept burning day and night, the position relative with flame sensor is provided with air inlet, and air inlet is provided with Venturi tube.
Further, described Venturi tube inlet end is provided with air regulator.
The beneficial effects of the utility model are: by the structural design of innovation, in altar lamp outside, electrode anti-explosion terminal box and sensor anti-explosion terminal box have been installed additional, make the electrical connection of altar lamp outside heating furnace meet explosion-proof relevant criterion, reach requirement of explosion proof, use safer; And the structure of improving altar lamp Venturi tube, fully mixes altar lamp combustion gas and combustion air, burns more stable, to adapt to the wide in range combustion chamber draft requirement of different heating-furnace.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of explosion-proof burner altar lamp that provides of the utility model specific embodiment.
In figure:
1, lamp bracket kept burning day and night; 2, ignitor; 3, flame sensor; 4, electrode anti-explosion terminal box; 5, sensor anti-explosion terminal box; 6, Venturi tube; 7, air regulator.
The specific embodiment
Below in conjunction with accompanying drawing and by the specific embodiment, further illustrate the technical solution of the utility model.
Fig. 1 is the structural representation of a kind of explosion-proof burner altar lamp that provides of the utility model specific embodiment.
As shown in Figure 1, a kind of explosion-proof burner altar lamp, comprises lamp bracket 1 kept burning day and night, ignitor 2 and flame sensor 3, and described ignitor 2 outsides are provided with electrode anti-explosion terminal box 4, and described flame sensor 3 outsides are provided with sensor anti-explosion terminal box 5.
Wherein, described electrode anti-explosion terminal box 4 and sensor anti-explosion terminal box 5 inside have spherical cavity, and are provided with opening at the two ends of described spherical cavity, and described opening is all connected with the mounting interface with cylindrical cavity; Described electrode anti-explosion terminal box 4 is connected with described lamp bracket kept burning day and night with the mounting interface of sensor anti-explosion terminal box 5 by one end, makes described ignitor and flame sensor all be positioned at its relative spherical cavity.
