- the steering position is in a particularly preferred manner thereby within the through the conveying directions (transport longitudinal axes) Dryer loading device (wet goods transport device) and the oven unloading device (Firing unloading device) included angle. Because of this arrangement the helm also extends close to the molding plant and near the Packing line.
- This control station arrangement according to the invention ensures that all machinery and conveyor systems required for the production as well as the Dried goods and the fired goods viewed from a single location and can be controlled.
- the invention relates to a plant for the continuous production of fired heavy clay products, especially bricks and / or roof tiles.
- the system is in a rectangular hall housed.
- the width B can be approximately 80 m and the length L approximately 100 m be.
- the raw materials required for molding such as clay and loam, as well any additives, such as coal, sawdust or the like, are with a charger Box feeder 1 fed.
- the conveyor belts are not numbered Raw materials in a preferred manner to a blow bar mill 2, a roughing mill 3 and a high-performance rolling mill 4.
- the material is fed to a conveyor belt Wet roller gear 5 fed.
- the conveyor belts for the aforementioned facilities 1 - 5 extend parallel to the walls of Hall H to save space, just like that conveyor belt (s) connected to the wet roller conveyor 5.
- the conveyor line downstream of the wet roller conveyor 5 (for material storage loading) is totaled 6.
- the processed material is rotated around a central vertical axis Filling conveyor belt 7 a material store designated as a whole with M, in particular Hall with circular mixing bed or circular sump, fed and on a so-called Ringhalde heaped up and stored.
- the material warehouse M includes an im essentially designed as a rotunda or polygon with the Material handling facilities.
- the material warehouse M takes up almost the entire center of a dry and Existing ring tunnel system. It is preferably that big dimensioned that in the production of building bricks a material supply for about one Week and for roof tile production a material supply for about three weeks can be stored.
- the raw material is removed from the ring stockpile of the material store M by one central vertical axis rotatable and as a whole with 8 numbered material removal device, such as bucket chain excavators, scraper or the like, dismantled.
- the material comes to a number 13 as a whole Shaping device, which preferably consists of a vacuum screw press, a mouthpiece and a cutter and with which the moldings F, such as blank tiles or tiles.
- a so-called Wet transport device 14 the molded articles F produced at 13 arrive at 15 numbered transport path on which the moldings F through on a circular path an annular, not completely closed in the circular shape - d. H. on one Circle sector open - tunnel dryer 16 can be transported. The dryer transport are fed to the drying tunnel in cycles and moved through it. Dryer entry and dryer exit can be designed in a known manner.
- the circularly curved tunnel dryer 16 extends outside of one also not completely closed with the release of a loading and unloading point tunnel furnace 17, which is curved in a circular shape and whose is rotating on a circle Transport path is numbered 18, concentric around the material store M.
- the moldings F are by means of a Translation device (transfer device) 19 to the means of transport for the Burning process set.
- the transport path 18 guides the molded articles F to be burned intermittently to and through the tunnel furnace 17.
- the fired products P in particular tiles or roof tiles
- an unloading device 20 of the Removed furnace transport means and fed to a packaging device 21.
- the finished product packages then reach a pallet storage belt 22, the required empty pallets via a conveyor track numbered 23 (preferably chain conveyor) are fed.
- the material store M is in the area of the material store the tunnel oven 17 in the basic form and the tunnel dryer 16 in the Basic shape are circular.
- the material store M is there in the center and is surrounded by tunnel kiln 17.
- the outermost annulus is from Tunnel dryer 16 formed. This results in the same stocking density due to larger tunnel length automatically a longer drying time compared to the burning time.
- All three circular rings (ring pile, drying and burning tunnel) are in one circular sector open, the open part of the material stockpile being mobile (i.e. moving) and the stockpile between the filling of the material store M through the Filling conveyor belt 7 and the clearing of the ring pile dump cone under the action the material removal device 8 extends.
- the open ring portion of the tunnel dryer 16 and tunnel furnace 17 is through the same assigned transport tracks 15/18 to form a closed circular ring.
- tunnel ends of the tunnel dryer 16 and tunnel oven 17 run radially to Material warehouse center. At least one tunnel end of tunnel dryer 16 and Tunnel furnace 17 lie on a common radial - in the illustrated This applies to the exits.
- the transport axis of the Wet transport device (drying material loading device) 14, the Translation device (dry transport device) 19 and the kiln unloading device 20 radial to the center of the material store.
- a control station numbered 24 is in the range of tunnelless circular sectors of the dryer-furnace tunnel system near the loading and Unloading devices (Pos. 14, 19, 20) arranged. There is also a small one Distance to the shaping device 13 and packaging device 21.
- the ring-shaped tunnels run dryer and oven side by side.
- the transport tracks 15 and 18 can be of trolleys, pallets / plates or rolls be formed - a combination of such means of transport is also possible.
- the orbits of the transporting moldings 15, 18 are the Top view of the system according to the invention.
- a particularly advantageous (simple and inexpensive) embodiment of the invention results if the central material store M serves as a support structure for a 25 numbered hall roof is used, this is particularly useful with a system "Rundsumpf", where a stable outer wall (hall wall) is used anyway.
