All of these formations define an interior space 8 in which carriages 12 loaded with bars 14 can move along rails 10 fixed to the furnace bottom 6.
V prubehu sušení a vypalování se vozíky 12 pohybuj í prerušovane po celé délce pece, pričemž jsou postupne zastavovány v ruzných částech pece po vhodnou dobu.During drying and firing, the carriages 12 move intermittently along the length of the furnace, gradually stopping in different parts of the furnace for a suitable period of time.
Postranní steny 2 jsou vytvorený radou modulu 16 panelového tvaru , které jsou uložený vedie sebe, jak je zrejmé z obr. 2.The side walls 2 are formed by a series of panel-shaped modules 16, which are stacked side by side, as shown in FIG. Second
Každý modul 16 je tvoren vnitrní vrstvou 18 z žáruvzdorného nebo proti teplu odolného materiálu, napríklad ze smesi šamotu, cementu s obsahem oxidu hlinitého nebo kaolinové vlny, mezivrstvou 20 z tepelne izolačního materiálu, napríklad z vermikulitu nebo kaolinové vlny a zevní nosnou vrstvou 24 z cementu, betónu nebo podobného materiálu. Spodní část zevní nosné vrstvy 24 tvorí bazi 26 pro uložení mezivrstvy 20 a vnitrní vrstvy 18 . Baze 26 je opatrená dutinou k vylehčení materiálu, dutina je vyplnená napríklad expandovaným polystyrenem.Each module 16 is formed by an inner layer 18 of a refractory or heat resistant material, for example a mixture of chamotte, cement containing alumina or kaolin wool, an intermediate layer 20 of a thermal insulation material, for example vermiculite or kaolin wool, and an outer backing layer 24 of cement. , concrete or similar material. The lower portion of the outer support layer 24 forms a base 26 for receiving the intermediate layer 20 and the inner layer 18. The base 26 is provided with a cavity to lighten the material, the cavity being filled, for example, with expanded polystyrene.
Rada výztužných prvku 27 protáhlého tvaru je zakotvená jedním svým koncern v zevní nosné vrstve 24 a druhým ve vnitrní vrstve 18 a prochází mezivrstvou 20, takže drží panel pohromade- Konce výztužných prvku 27 mohou mít tvar V nebo mohou být vytvorený ve tvaru háku, aby byla usnadnena soudržnost panelu.The array of elongate-shaped reinforcing elements 27 is anchored by one of their concerns in the outer support layer 24 and the other in the inner layer 18 and passes through the interlayer 20 to hold the panel together. The ends of the reinforcing elements 27 may be V-shaped or hook-shaped to facilitated panel consistency.
Zevní nosná vrstva 24 je opatrená zesilující mríží 29. Mimoto je rovnež opatrená podélnou dutinou 30, obsahující dutou cihlo.u 32 . Podélná dutina 30 komunikuje se zevním prostorem dvojici otvoru 34 v horní a ve spodní části panelu 16. V prípade, že je pec v chodu, je tedy možno vytvorit proud vzduchu otvory 34 a dutinami v duté cihle.The outer backing layer 24 is provided with a reinforcing grid 29. In addition, it is also provided with a longitudinal cavity 30 comprising a hollow brick 32. The longitudinal cavity 30 communicates with the external space of a pair of apertures 34 at the top and bottom of the panel 16. Thus, when the furnace is running, it is possible to create an air flow through the apertures 34 and through the cavities in the hollow brick.
a tím chladit zevní stenu pece.thereby cooling the outer wall of the furnace.
Povrch vnitrní vrstvy 18, která je žáruvzdorná a prichází do styku s vnitrní atmosférou pece je opatren radou zárezu 36, aby nedošlo k prasknutí žárovzdorného materiálu, zpusobeného tepelným zatížením, jemuž je materiál vystaven a aby se materiál mohl alespoň do určité míry roztahovat. Hloubka zárezu 36 je menší než tlouštka vnitrní vrstvy 18, která je žáruvzdorná. Zárezy 36 se však mohou ponékud prohloubit v prubehu času. Za zárezy 36 jsou uložený duté žáruvzdorné cihly : 38, které jsou ve styku s mezivrstvou 20, aby se horký vzduch z pece nedostal do prímého styku s materiálem mezivrstvy 20, který je proti pusobení tepla méné odolný.The surface of the inner layer 18, which is refractory and comes into contact with the interior atmosphere of the furnace, is provided with a plurality of notches 36 to prevent the refractory material from being exposed to the thermal load to which the material is exposed and to expand the material at least to some extent. The depth of the notch 36 is less than the thickness of the inner layer 18, which is refractory. However, the slits 36 may deepen somewhat over time. Hollow refractory bricks 38 are placed behind the slits 36, which are in contact with the interlayer 20 so that the hot air from the furnace does not come into direct contact with the interlayer material 20, which is less resistant to heat.
Panel 16 je opatren dvojici pruchozích otvoru 40, uložených nad sebou na jeho strední čáre. Do techto pruchozích otvoru 40 je možno tesne uložit objímky pro horáky bežného typu, užívané v cihlových pecích, pro prístroje pro prívod vzduchu nebo je možno pruchozí otvory 40 uzavrít zátkami. Vhodné rozmísténí pruchozích otvoru 40 v rade modulu 16, uložených vedie sebe a tvorících postranní steny cihlové pece umožní požadovaný nejvýhodnejší tepelný profil pro jakékoliv špecifické požadavky, týkající se provozu této pece.The panel 16 is provided with a pair of through holes 40 superimposed on its center line. These openings 40 can be tightly housed for burners of conventional type used in brick furnaces, for air supply devices, or the openings 40 can be closed with plugs. Appropriate placement of the through holes 40 in the row of module 16 extending side by side and forming the side walls of the brick furnace will allow the desired most favorable heat profile for any specific requirements regarding the operation of the furnace.
Šírka 44 každého panelu 16 je s výhodou rovná délce každého vozíku 12 nebo je jejím podílem. Pri chodu pece se vozíky 12 zastavuj! se svými stredovými částmi privrácenými k rohraní mezi dvema sousedními panely 16. Jakékoliv horáky, uložené v pruchozích otvorech 40 panelu 16 zasahuj! tedy do prázdného prostoru mezi dvema za sebou následujícími vozíky 12, čímž je možno bránit poškození cihel jejich príliš blízkým uložením u horáku.The width 44 of each panel 16 is preferably equal to or a proportion of the length of each carriage 12. The carts 12 stop when the furnace is running! with its central portions facing the corner between two adjacent panels 16. Any burners housed in the through holes 40 of the panel 16 interfere! that is, into the empty space between two consecutive carriages 12, whereby it is possible to prevent damage to the bricks by placing them too close to the burner.
V dalším neznázornéném provedení vynálezu by bylo možno vytvorit vnitrní vrstvu i mezivrstvu panelu z téhož materiálu, odolného proti pusobení tepla a tepelne izolačního, napríklad z kaolinové vlny.In another embodiment of the invention, not shown, it would be possible to form both the inner layer and the intermediate layer of a panel of the same heat-resistant and heat-insulating material, for example of kaolin wool.
