Abstract
The utility model discloses a silicon nitride dry point type electric heating device for the tobacco industry. The electric heating device comprises a silicon nitride ceramic matrix in which a heating wire is embedded. The electric heating device has the advantages of small size, light weight, long service life, high temperature resistance, fast temperature rising speed and corrosion resistance; after the surface of a heating pipe is stained with glue, the glue can be burnt up with high temperature by the electric heating device, so that the heating pipe does not need to be replaced frequently; the problems such as rusting, slow temperature rising, glue staining and frequent maintenance of the heating pipes of tobacco machinery and packing machinery are solved; the silicon nitride ceramic electric heating device is a brand-new electric heating device applied in the tobacco machinery and the packing machinery; and the electric heating device with the silicon nitride ceramic matrix can be used for saving time, labor and energy.
Description
Technical field
The utility model relates to electric calorifie installation, specifically, relates to a kind of silicon nitride that is used for tobacco business and does the type electric calorifie installation, is used for tobacco machine, package packing machine heating field.
Background technology
Tobacco machine, package packing machine are provided with roasting adhesive dispenser, and roasting adhesive dispenser surface must be smooth, to prevent roasting adhesive dispenser viscose glue; But traditional tobacco machine, package packing machine immerging metal tube heater still are easy to viscose glue, and the product of producing behind the viscose glue causes waste product or defective item easily; And roasting adhesive dispenser gets rusty very soon, and because the heating tube surface after getting rusty is no longer smooth, makes heating tube surface viscose glue more easily; So must in time change heating tube, just caused the waste of human resources and goods and materials since so, this is owing to heat up slowly during the roasting glue of existing electric calorifie installation; Lose time, the energy and manpower and materials; And then increased production cost, and the heating element structure of existing roasting adhesive dispenser is complicated, and maintain and replace is inconvenient.
The utility model content
The utility model has overcome shortcoming of the prior art; Provide a kind of silicon nitride that is used for tobacco business to do the type electric calorifie installation; Solved the leftover problem of traditional tobacco machine, package packing machine; The utlity model has that long, high temperature resistant, programming rate of life-span is fast, corrosion resistance, advantage of simple structure, and can fall with high-temp combustion behind the viscose glue of heating tube surface, reduced production cost.
In order to solve the problems of the technologies described above, the utility model is realized through following technical scheme:
A kind of silicon nitride that is used for tobacco business is done the type electric calorifie installation, comprises the silicon nitride ceramics matrix, is embedded with heating wire in the said silicon nitride ceramics matrix.
Further, said heating wire connects lead through the lead solder joint.
Further, said heating wire is a tungsten filament.
Further, said tungsten filament is a helical tungsten filamen.
Compared with prior art, the beneficial effect of the utility model is:
The utility model possesses that volume is little, in light weight, the life-span is long, high temperature resistant, programming rate is fast and corrosion resistant advantage; Can glue be fallen with high-temp combustion through the utility model behind the viscose glue of heating tube surface; Needn't often change heating tube; Solved tobacco machine, package packing machine heating tube get rusty problem, the slow problem that heats up, viscose glue problem, often keep in repair the heat-generating pipe problem; The silicon nitride ceramics electric calorifie installation is to be applied in electric calorifie installation brand-new in tobacco machine, the package packing machine, and adopt silicon nitride ceramics matrix electric calorifie installation not only save time, laborsaving can also be energy-conservation.
Description of drawings
Accompanying drawing is used to provide the further understanding to the utility model, is used to explain the utility model with the embodiment of the utility model, does not constitute the restriction to the utility model, in the accompanying drawings:
Fig. 1 is the structural representation of the utility model.
Among the figure, 1---the silicon nitride ceramics matrix;
2---tungsten filament;
3---the lead solder joint;
4---lead;
5---middle polyphone solder joint.
Embodiment
Describe below in conjunction with the preferred embodiment of accompanying drawing, should be appreciated that preferred embodiment described herein only is used for explanation and explains the utility model, and be not used in qualification the utility model the utility model.
As shown in Figure 1, the described a kind of silicon nitride that is used for tobacco business of the utility model is done the type electric calorifie installation, comprises silicon nitride ceramics matrix 1; Be embedded with heating wire in the silicon nitride ceramics matrix 1, in the present embodiment, heating wire is a tungsten filament 2; Tungsten filament 2 heating effects are good, and the mode that tungsten filament 2 adopts Luo to revolve is embedded in the silicon nitride ceramics matrix 1, and heating effect is better; Heating wire connects lead 4 through lead solder joint 3, and syndeton is simple, helps the assembling of the utility model; Present embodiment adopts two groups of silicon nitride ceramics matrixes 1, and two ends connect lead 4 respectively, polyphone solder joint 5 series connection in the middle of middle the employing; Programming rate is faster, also can adopt one group, three groups or more than, it is all in the protection range of the utility model.
Adopt the high purity silicon nitride powder to make silicon nitride ceramics matrix 1, be that the pyrotoxin material is embedded in silicon nitride ceramics matrix 1 raw material with tungsten filament 2; Through high temperature, high-pressure sinter; Form high-compactness, high-intensity heating matrix, heating wire is worked, is made to have the useful life of silicon nitride ceramics electric calorifie installation significantly in the environment of a complete closed and promotes.
What should explain at last is: more than be merely the preferred embodiment of the utility model; Be not limited to the utility model; Although with reference to embodiment the utility model has been carried out detailed explanation, for a person skilled in the art, it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing; Perhaps part technical characterictic wherein is equal to replacement; But all within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection range of the utility model.
