Abstract
A heater structure of an electronic powder firing furnace belongs to the technical field of the electronic product firing furnace. The heater structure comprises a heater body and a protection tube, wherein the middle part of the heater body in the length direction is located within the cavity of the protection tube, while the two ends thereof extend out of the cavity of the protection tube; a first temperature resistant spacer bush and a second temperature resistant spacer bush are arranged at the two ends of the cavity, respectively; the end faces of the first temperature resistant spacer bush and the second temperature resistant spacer bush are in contact with each other, and both of the first temperature resistant spacer bush and the second temperature resistant spacer bush are arranged on the heater body, and wherein the first temperature resistant spacer bush extends to the cavity opening part of the cavity and is sealed by a sealing packing course. The heater structure has the following advantage that: the severe atmosphere in the hearth can be effectively prevented from affecting the heater body so that the heater body can work normally and enduringly, which is advantageous not only to ensure the sintering quality of an electronic powder material and but also to save the use cost and ensure the normal operation of the electronic powder firing furnace.
Description
Technical field
The invention belongs to electronic product burning kiln technical field, be specifically related to a kind of heater structure of electronic powder firing furnace, be used for air furnace, atmosphere furnace such as nitrogen furnace, nitrogen are added the heating of hydrogen furnace etc.
Background technology
such as industry the reason of knowledge, the sintering process of electronic powder material whether stablize the quality that can directly have influence on electronic product, and the sintering quality to electronic powder whether in proper working order of heater produces corresponding influence.Heater in the prior art all be directly exposed be arranged in burner hearth up and down and/or about, and use Elema and siderochrome aluminium, chromium nickel METAL HEATING PROCESS silk usually.This heater strip can't produce unfavorable factor under air atmosphere, that is to say in the atmosphere of no special corrosion, can normally to use.But when for example the battery used of new-energy automobile is with the powder body material sintering to some new material; The organic matter that this kind material can volatilize a large amount of steam, corrosive gas and have viscosity when heating, these materials tend to attached on the heater, and for example steam causes the heater strip short circuit; The colloid that and for example adheres to causes hot-spot and the scaling loss heater; Make normally sintering electronic powder of heater, gently then influence product quality, can make product rejection when serious.In addition, the service life of above-mentioned heater strip is of short duration because of being corroded, and generally about one month, need change, and not only causes use cost to increase, and influences the operate as normal of firing furnace.
In view of above-mentioned prior art, be necessary to improve, to this, the applicant has done actively and good try has found the way of dealing with problems, and the technical scheme that will introduce below produces under this background
Summary of the invention
task of the present invention be to provide a kind of be suitable for operate as normal under adverse circumstances atmosphere and use guarantee to the sintering quality of electronic powder, avoid causing the heater structure that increases and influence the electronic powder firing furnace that burns till efficient of firing furnace with cost because of the frequent change heater strip.
task of the present invention is accomplished like this; A kind of heater structure of electronic powder firing furnace comprises heater body and protection tube, and the middle part of the length direction of heater body is positioned at the tube chamber of protection tube; And two ends lean out the tube chamber of protection tube; Respectively be provided with one first heatproof spacer and one second heatproof spacer at the tube chamber two ends, the end face of first, second heatproof spacer contacts with each other, and all is placed on the described heater body; Wherein: the first heatproof spacer extends to the accent position of tube chamber, and by the sealing of sealing packing course.
in a concrete embodiment of the present invention, described heater body is Elema or resistance wire rod.
in another concrete embodiment of the present invention, the described first heatproof spacer is 1000 type alumina silicate fibre covers; And the described second heatproof spacer is 1400 type alumina silicate fibre covers.
in another concrete embodiment of the present invention, described sealing packing course is a silica cement.
in another concrete embodiment of the present invention, described protection tube is quartz ampoule or alumina tube.
also have among the concrete embodiment of the present invention, and described alumina tube is the surface porcelain alumina tube.
technical scheme provided by the invention is owing to protect heater body through protection tube; And respectively be equipped with first, second heatproof spacer at the intraluminal two ends that are positioned at protection tube corresponding to heater body; The time and be provided with the sealing packing course sealing that is used for the end face sealing of the first heatproof spacer at the accent position of tube chamber; Thereby can stop the abominable atmosphere in the burner hearth to influence heater body effectively; Make heater body be able to operate as normal enduringly; Help to guarantee the sintering quality of electronic powder material, and need not to resemble frequent change heater body the prior art, help practicing thrift use cost and the operate as normal that ensures electronic powder firing furnace.
Description of drawings
Fig. 1 is concrete embodiment of the present invention and application examples structure chart.
The specific embodiment
can be expressly understood technical spirit of the present invention and beneficial effect more for the auditor that the makes Patent Office especially public; The applicant general elaborates with the mode of embodiment below; But the description to embodiment all is not the restriction to the present invention program, any according to the present invention design done only for pro forma but not substantial equivalent transformation all should be regarded as technical scheme category of the present invention.
Embodiment 1:
are in Fig. 1; The applicant shows the body of heater 3 of electronic powder firing furnace; Body of heater 3 has a burner hearth 31; During use, electronic powder material 41 to be burnt till carries on load bearing board 4 and by load bearing board 4 introduces burner hearth 31, and is arranged at intervals with the thermocouple 32 that is used to predict the temperature in the furnace chamber 31 at the length direction of body of heater 3.
heater structure provided by the invention is provided with along the length direction of aforesaid burner hearth 31 at interval; This heater structure comprises heater body 1 and protection tube 2; The middle part of heater body 1 is positioned at the tube chamber 21 of protection tube 2; And two ends are stretched over outside the tube chamber 21, fix with illustrated body of heater 3.Each is provided with one first heatproof spacer 211 and one second heatproof spacer 212 successively at the two ends of the tube chamber 21 of heating tube 2, and first, second heatproof spacer 211,212 is connected each other, and promptly both end faces contact.Wherein, the second heatproof spacer 212 is positioned at the inboard of the first heatproof spacer 211, promptly is positioned at the inner of the length direction of tube chamber 21.The first heatproof spacer 211 towards the position of the accent of tube chamber 21 with 2111 sealings of sealing packing course.
