Abstract

SUMMARY OF THE INVENTION: The furnace comprises a working channel 1, limited by side walls, a roof and a bottom 4, and a plunger. Under 4 is installed with the possibility of reciprocating movement, and the pusher is made in the form of a set of transverse partitions 7 installed in the working channel 1 with the possibility of reciprocating movement in a vertical plane. In this case, the partitions 7 are rigidly fixed on the arch, and the arch itself is installed with the possibility of reciprocating movement. 5 hp F-lu, 3 Il.

The invention relates to thermal equipment for the firing of bricks and may find application in the building materials industry.

A known tunnel kiln for firing building materials, containing a working channel bounded by side walls, roof and hearth, on the last of which rail tracks for furnace cars are installed, and a pusher of cars.

The closest to the technical essence and the achieved effect to the proposed is a high-temperature tunnel pusher furnace containing a working channel bounded by side walls, roof and movable hearth, plate conveyor and pusher.

A disadvantage of the known furnaces is the need for overrunning ways, which complicates their design, increases in size and significant heat loss caused by cooling the trolley on the overrunning ways.

The purpose of the invention is to reduce the size of the furnace and increase the efficiency of use of heat and power resources.

The goal is achieved by the fact that in the furnace containing a working channel bounded by side walls, roof and movable hearth, and the plunger is installed with the possibility of reciprocating movement, and the plunger is made in the form of a set of transverse partitions installed in the working channel -accessible movement in the vertical plane.

Partitions are rigidly fixed on the roof of the furnace, installed with the possibility of reciprocating movement in a vertical plane.

In addition, the partitions are rigidly fixed on beams installed with the possibility of reciprocating movement in a vertical position. In this case, the beams can be mainly placed above the roof of the furnace, and the partitions are passed through vertical channels made in the roof of the furnace.

In addition, the partitions are perforated and installed with a step equal to the pitch of the furnace.

Figure 1 shows the proposed oven, a longitudinal section; figure 2 - section aa in figure 1; FIG. 3 shows an oven, an embodiment.

The furnace contains a working channel 1, limited by side walls 2, roof 3 and hearth 4, installed with the possibility of reciprocating movement

on roller 5 in the horizontal plane, and a pusher of bricks 6, made in the form of a set of transverse partitions 7, which are installed in the working channel 1 with the possibility of reciprocating movement in the vertical plane.

At the same time, in one of the embodiments of the furnace, the partitions 7 are rigidly fixed to the frame 8 of the roof 3, and the roof 3 is installed with the possibility of reciprocating movement in the vertical plane. In another embodiment of the furnace, the partitions 7 are rigidly fixed to beams 9 installed with the possibility of reciprocating and moving, located above the roof 3, and the partitions 7 are passed through vertical channels 10 made in the roof 3. Sand seals 11 are provided to seal the furnace. 7 perforation holes 12 are made, which improves the maintenance of the thermal mode of the furnace. The distance (pitch) between the dividers 7, as a rule, is assumed to be equal to the step of moving the hearth. To prevent the channel 1 from burning with baked bricks, guides (not shown) are provided in the lining 13 of the hearth 4, and

the lining 13 to facilitate the replacement of worn areas can be made of individual tightly-mounted units one to another 14. To replace the worn areas of the lining 13 under 4 completely or

partially rolled out of the furnace.

The furnace works as follows. In the loading position, under 4 is in the extreme right position (shown by the dotted line in FIG. 1), the arch 3 is fixed to

it partitions 7 - in the extreme upper position (shown by the dotted line in figure 2). After laying another batch of raw brick under 4, it moves to the extreme left position to the unloading position,

achieving which the vault 3 with partitions 7 descends into. the lowest position until they overlap at least half the height of the brick 6. After unloading the next batch of finished

brick 4 is returned to the loading position. At the same time, the partitions 7 hold the bricks 6 in place relative to their position in the working channel 1 and thus move them along the guides made in the lining 13 one step in the direction of discharge. As soon as under 4 stops at the loading position, the arch 3 with partitions 7 rises to the extreme upper position and the whole cycle is repeated from the beginning.

The use of the invention allows to simplify the design of the furnace, to reduce its dimensions by eliminating the installation of the bypass tracks, as well as to increase the efficiency of use of fuel and energy resources by reducing heat loss.
