Description

one

The present invention relates to the field of building materials.

A famous kiln for the manufacture of ceramic products, consisting of a shaft, in the lower part connected to the tunnel channel, and a charging device.

The aim of the invention is to increase the productivity of the furnace and the quality of the product.

For this, the shaft in the upper loading section is covered with many brown, mostly double-trough grates with perforated bottoms and perforated flat grids located under them, mounted for rotation by means of an actuator, and nozzles are installed in the bottom of the furnace shaft.

FIG. 1 depicts the oven described, longitudinal section; in fig. 2 - double brown grilles.

The furnace consists of a shaft / and a tunnel channel 2.

The shaft in the upper loading part is blocked by two-bay trough-shaped lattices 3 with perforated bottoms and flat perforated lattices 4 located under them, which rotate through the hollow shafts 5- and b. Nozzles 7 are installed in the lower part of the mine.

The furnace works as follows.

A layer of raw granules of clay 2-3 cm thick are poured onto a layer of sand between sandstone bricks placed along the edges of the trolley 8. The trolley is sent to the zone of preliminary heat treatment of the furnace channel where the clay granules are dried using a push rod. Next, the trolley with heat-treated granules enters the expansion zone, located

under the mine, where the swelling of a layer of clay granules.

Simultaneously with the preparation of clay granules on the trolley, in the preheating zone of the furnace, drying is carried out and

heat treatment of raw clay granules in the mine. For drying, raw clay granules are loaded into the upper shaft of the mine, which is at the same time a consumable bunker. Dried granules fall asleep.

through flat perforated lattices 4 to the lower Russian of Schacht.

By rotating the shaft, 6 portions of the pre-heat-treated clay granules from the bottom rus through the flat perforated grids 4 fall asleep and swell on the previously expanded layer on the car coming from the pre-heat treatment zone of the furnace. Required product thickness is reached

by multiple portions of backfill and expansion of the clay granules on the trolley. Trolleys with finished products from the swelling zone enter the cooling area. In order to ensure a stable heat treatment mode, the preliminary heat treatment, expansion and cooling zones are separated from each other by movable cooled partitions 9. Subject of the invention A furnace for the manufacture of porous products, containing a shaft in the lower part connected to the tunnel channel, is characterized in that productivity and quality of products, the mine in the upper loading section is covered with many brown, mostly double brown, trough-shaped grids with perforated days , S and disposed beneath the perforated flat bars mounted with the possibility vragtseii by the actuator, and the nozzle installed in the lower part of the furnace shaft.
