Abstract
The utility model relates to a dry ignition type silicon nitrogen ceramic electric heating device, which comprises a heating main body and a lead connected with the heating main body; the heating main body is made of silicon nitrogen ceramic; the heating main body is in a tubular structure; an electric element is arranged in the heating main body; and the electric heating element is connected with the lead. According to the device provided by the utility model, as the electric heating element is arranged in the heating main body, the heating main body can be preheated; thus, the fuel or gas can be ignited as soon as being be released, thereby reaching the requirements of safety, reliability and energy conservation; as the heating main body is arranged to be a tubular structure, the heat dissipation area of the heating main body can be enlarged, thus, the surrounding space of the heating main body can be heated; and moreover, as the heating main body is made of silicon nitrogen ceramic, the device is high temperature resistant and corrosion resistant, thus, the service life of the ignition device can be greatly prolonged, and the device is a novel electric heating element which integrates preheating, ignition and heating functions.
Description
Technical field
The utility model relates to the combustion preheater technical field of fuel gas, more specifically, relates to a kind of type silicon nitride ceramics electric calorifie installation of doing.
Background technology
Traditional igniter adopts pulse to produce instantaneous pressure formation electric spark and accomplishes ignition process; So before igniting, must discharge fuel oil or combustion gas earlier and then light a fire; This sparking mode not only wastes energy, and the more important thing is that long-time use forms threat to operator's health, gently then causes gassing; Weight person causes that gas burst directly influences operator's the security of the lives and property, and the operator who is engaged in this work for a long time also suffers from occupational disease easily; Simultaneously, traditional igniter mostly adopts metalwork production, corrosion-resistant and high-temperature behavior be not good, cause existing igniter mostly useful life not long.
The utility model content
The purpose of the utility model overcomes the deficiency of prior art exactly, and a kind of type silicon nitride ceramics electric calorifie installation of doing is provided, and this component structure is simple, and is safe and efficient.
In order to achieve the above object, adopt following technical scheme:
A kind of type silicon nitride ceramics electric calorifie installation of doing; Comprise heating body and the lead that is connected with the heating body, said heating body material is a silicon nitride ceramics, and said heating body is platy structure; Its set inside has electric heating element, and said electric heating element links to each other with lead.
Further, said electric heating element is at least two, the parallel heating body interior that is distributed in.
Further, said heating body is forming the U-shaped opening near the lead direction, and said U-shaped opening is provided with welding block at end position, and said lead is connected with welding block with electric heating element.
Again further, said electric heating element is the metal heating wire.
Also further, said metal heating wire is a tungsten filament.
Compared with prior art, the beneficial effect of the utility model is:
In the heating body, electric heating element is set; Can realize preheating to the heating body; Misfire or light a fire when solving the fuel system cold start-up difficult problem, further guarantee that fuel oil or combustion gas are lighted once discharging, thereby reach safety, reliably and requirements of saving energy; The body that generates heat is set to platy structure, can increase the area of dissipation of heating body, helps the surrounding space of heating body is heated fast; Heating body material is selected silicon nitride ceramics for use, can high temperature resistant and corrosion, solved the problem that the metal tube heater can't be worked on the one hand under hot environment, and make the life-span of igniter significantly increase on the other hand.
Description of drawings
Fig. 1 is the said structural representation of doing type silicon nitride ceramics electric calorifie installation of the utility model
Fig. 2 is the schematic top plan view of Fig. 1.
Among the figure: the 1-lead; The 2-welding block; The 3-body that generates heat; The 4-tungsten filament.
Embodiment
Referring to accompanying drawing and specific embodiment, the utility model is further specified:
Referring to Fig. 1 and Fig. 2, the described type silicon nitride ceramics electric calorifie installation of doing of the utility model comprises heating body 3 and the lead 1 that is connected with heating body 3; Said heating body 3 materials are silicon nitride ceramics, and said heating body 3 is platy structure, and its set inside has electric heating element; Said electric heating element links to each other with lead 1, and in the present embodiment, said electric heating element 3 is at least two; Parallel heating body 3 inside that are distributed in, said heating body 3 is forming the U-shaped opening near lead 1 direction, and said U-shaped opening is provided with welding block 2 at end position; Said lead 1 is connected with welding block 2 with electric heating element 3, and said electric heating element is the metal heating wire, is preferably tungsten filament.When producing heating body 3; Earlier the high purity silicon nitride powder is mixed to matrix material, with special frock tungsten filament 7 is embedded in the matrix material by special prescription; Form high-compactness, high-intensity heating matrix through high temperature, high-pressure sinter at last, this heating matrix through the processing welding lead after again with ceramic packaging, heater element is worked in the environment of a complete closed.
Based on said structure; The utility model energising earlier in the course of the work lets tungsten filament 7 heating and heating body 3 carried out preheating, thereby when silicon nitride heating body 3 surface temperatures reach the burning-point of fuel oil or combustion gas, discharges fuel oil or combustion gas again, guarantee that fuel oil or combustion gas have just discharged just to light and reach safety, reliable and energy-conservation igniting requirement.
Should be appreciated that; The content that above specific embodiment is announced is merely the part preferred version of the utility model; Every technical scheme, meet the technical spirit of the utility model, belong to those skilled in the art and need not to carry out the protection range that enforcement that creative work can obtain all should belong to the utility model based on the utility model.
