SU34375A1 - Fryer for fumigating raw bricks - Google Patents

Description

The process of fumigating raw material in simple brick-burning (periodic) kilns is due to its primitiveness, and it is quite inconvenient and expensive, the fumigation operation takes a long time, the fuel consumption for fumigation is about all the fuel used for firing bricks. This, in most cases, is burned with expensive fuel; In addition, the regulation of goggles in the glasses and the distribution of firewood in the furnace is a lot of unrecoverable difficulties.

Defects in the baked brick appear mainly due to the abnormality of fumigation, making it impossible to regulate the fire, as required by the firing technique.

By the proposed roaster for fumigating a raw brick, it is meant that the above disadvantages are eliminated. In the drawing of FIG. 1 depicts the top view of a brazier; FIG. 2 is also a view (Adi; Fig. 1 is a front view, and Fig. 4 is a section along the line AB in Fig. 1.

The proposed fryer for fumigating a raw brick consists of a metal box placed on a wheel drive. The bottom of the box is slatted with narrow holes of the grates so that fine coal does not spill, as in the proposed roasting pan it is meant-use pol (506)

For fumigation, it is low-grade coal fuel. The magnitude of the roaster is calculated by means of the ocular holes and can be larger or smaller. The length of the brazier should cover three rolls silt arches. The brazier is also adapted for peat smoking. In this case, the grate at the bottom, the bottom of the chic, is closed, and a corresponding hole is left in the side wall of the car for air passage.

The roasting pan is filled with fuel / the lighted one is introduced into the inside of the firebox and pushed over to the tombs, set first in the front rows of shallows, where the gases always usually get worse. After the brazier is inserted into the firebox, the valve is closed for a long time; through the hole in the valve by means of the iron rod, the trolley is driven by a fireman. As the hot gases punch through the brazier and dry the raw material, the brazier is pushed further through to the next row of arches, drying, so that the rest of the furnace is dried until the whole glass is dried.

You can use several braziers at the same time, depending on the number of glasses in the chain. In this case, the firebox starts up.
