Abstract
The utility model discloses a hearth structure of a standing-style tubeless and constant-running sintering-furnace. The utility model comprises a standing hearth, a box-bowl and a kryptol or a resistant-wire bar. The utility model is characterized in that a guiding-rail brick is arranged in the middle of the hearth; the box-bowl is arranged in the guiding-rail brick; the kryptol or the resistant-wire bar is arranged on the two sides or around each couple of the guiding-rail brick. The sintering-furnace with the structure utility model can overcome the defects of the normal sintering-furnace and has reasonable structure, and then the unification and stability of the sintered products can be largely enhanced, and the eligibility rate can be raised, and the energy can be further saved and the economic efficiency can be raised.
Description
Technical field
The utility model relates to vertical sintering furnace, relates to a kind of nothing by it and manages vertical continuous fritting furnace chamber structure.
Background technology
Vertical sintering furnace is easy to use, widely applicable, be particularly suitable for the production of many kinds, medium and small output electronic ceramics series products, remarkable, the good product consistency of its economize on electricity, be widely used in the sintering of electronic ceramics series products such as thermistor, piezo-resistance, ceramic capacitor, chip capacitor, chip inductor, ceramic filter, buzzing sheet, magnetic material, and a kind of sintering furnace that boiler tube is set in chamber structure that gone on the market in the market, but the sintering furnace that is provided with the chamber structure of boiler tube has following shortcoming:
1, irregular (fire form by the refractory material) of saggar carrier physical dimension, gap meeting change at random when overlapping saggar carrier moves downwards in boiler tube and between the boiler tube inwall, therefore can cause airflow direction or power between saggar carrier and the boiler tube also to change thereupon, even stop up, that is to say: in the boiler tube variations in flow time, the temperature field also changes thereupon in the saggar, causes that the product in the saggar burns till the uniformity variation, and product percent of pass reduces;
2, because former burner hearth is provided with boiler tube, mode of heating is the radiant type heating.Because the thickness of boiler tube has heat-blocking action, be unfavorable for heat conduction and energy-conservation;
3, because boiler tube is that high-grade refractory material is made, and expense is more expensive, and is consumable accessory again, life cycle is generally 3-12 month, so original equipment structure operating cost is higher.
Summary of the invention
The technical problems to be solved in the utility model is how to provide a kind of nothing to manage vertical continuous fritting furnace chamber structure, sintering furnace with this chamber structure can overcome the shortcoming of above-mentioned sintering furnace, and it is rational in infrastructure, can improve greatly and burn till consistency of product and stability, improve qualification rate, more energy savings has increased business economic efficient.
Above-mentioned technical problem of the present utility model is to solve like this: provide a kind of nothing to manage vertical continuous fritting furnace chamber structure, comprise vertical furnace chamber, saggar and carbon-point or resistance wire rod, it is characterized in that, be provided with the guide rail brick in the middle of the described burner hearth, described saggar is positioned in the guide rail brick, the both sides of every pair of guide rail brick or described carbon-point is installed or the resistance wire rod on every side.
Manage vertical continuous fritting furnace chamber structure according to nothing provided by the utility model, it is characterized in that, described burner hearth is a cube, and carbon-point or resistance wire rod can be divided into one or more tunnel with described burner hearth, all is provided with a pair of in each tunnel or two pairs of guide rail bricks.
Manage vertical continuous fritting furnace chamber structure according to nothing provided by the utility model, it is characterized in that, described guide rail brick can be provided with a plurality of warm areas on short transverse, all is provided with the partition brick between per two warm areas.
All be provided with boiler tube in the chamber structure of at present all vertical continuous fritting furnaces, the effect of this boiler tube is to play the guiding role when overlapping saggar carrier moves downwards in boiler tube, and nothing provided by the utility model is managed vertical continuous fritting furnace chamber structure, boiler tube is not set in the middle of the burner hearth, and replace with the guide rail brick, its operation principle is: the saggar carrier after overlapping is motion downwards in the guide rail brick, heating element heater is positioned over saggar carrier bilateral type or all around, because heating element heater is away from the saggar carrier, and saggar carrier variable-sized less when in the guide rail brick, moving, therefore the variation because of saggar carrier physical dimension will can not cause the variation of air-flow in the burner hearth again, temperature is constant in the burner hearth, and it is all right to burn till consistency of product.In addition do not establish boiler tube in the burner hearth, become the directly-heated type heating by the heating of primary radiation formula, energy savings more, equipment does not have consumable accessory (boiler tube) and effectively reduces equipment operating cost, has increased business economic efficient.
