Description

The invention relates to bottom sushi-JIOK, in which the material is heated - thanks to the heat conduction of the hearth, under which chimneys are arranged. In the sand drying device, which represents a fire chamber and a chamber open from above, which has a system of smoke channels under the hearth, it is proposed that the space formed by double walls of the chamber be divided by partitions along the entire height of the side channels and partitions that do not reach to the top, They are continued by the lower horizontal channels in order to connect the last zigzag smoke channel into one side of the chamber.

In FIG. 1 shows in axonometric view a view of the proposed device, FIG. 2 is a view from the side of the door; FIG. 3 is a horizontal longitudinal section of the device above the grate of the combustion chamber; FIG. 4 is a section along AB of FIG. 3 and FIG. 5 is a section through EF of FIG. four.

The proposed device consists of, a firebox 2 with a grate 4, a drying chamber 1, partitions 17, 18, 19, running along the entire height of the side walls, partitions 10, 12, 14, not income. leading to the top of these walls, and horizontal channels. E, 11, 13 and 15 for gases. The device has for drying sand

an open chamber 1 above, a layer of refractory bricks. The chambers 1 are supported on brick walls .23, between which horizontal smoke channels 9, 11, 13, 15 are formed. Some of the brick walls rise on the sides of chamber 1 and form partitions 10, 18, 19, 12, 14, 17, separating chimneys are one from the other, where the peregorydki 17, 18, 19 go along the entire height of the walls, and the partitions 10, 12, 14 do not reach m to the top. Chamber 1 has doors 19 for scrapping dried sand (Fig. 2) and is heated by a furnace consisting of a combustion chamber 2 with a flue hole 5 and blowing 3 with a hole 6 for scooping ash and air flow. The device protrudes above the ground to a height of one meter and is fastened on each side with squares 20, strips 21 and taps 22. Smoke and gases enter the pipe through hole 16.

When the doors 19 are closed, raw sand is poured into chamber 1 and fire is simultaneously set off in furnace 2. Hot gases, going past the rear wall of chamber 1 through chimney 7, are directed through the opening in the partition 8 along the side wall of the chamber rise, go up and pass through the hole in the partition 10 into the next chimney 11, where they go under the furnace again, rise up again and pass through the hole to the partition 12 in the side wall of the chamber down, go down the chimney 13 under the chamber 1, from where they climb the side wall upward through the passage opening in the partition 14 in the chimney 15, are under the time--Update lodom furnace and exit through opening 16 into the tube.

Subject patent.

A device for drying sand, consisting of a fire chamber and an open-top chamber, provided at the bottom, under the hearth with smoke channels, characterized in that the double walls of the chamber 1 formed by partitions 17, 18, 19, v extending over the entire height of the side walls, and; the partitions 12, 14, 10 that do not reach the top are divided into channels that serve as continuation of the lower, horizontal channels 9, 11, 13, 15 in order to connect the latter into one zigzag smoke channel covering the chamber from three: the toron.
