SU16798A1 - Furnace for drying sand, burning boilers and boiling mastic - Google Patents

Description

In the proposed kiln for drying sand, firing boilers and cooking mastic, in order to save fuel, two identical centers are used for cooking mastic, in which chimneys from the firebox move upwards and pass through the passes into the space surrounding the boiler and communicate with a boar supplied with regulating gates for directing gases or to a compartment with a plate for drying sand and a chamber for firing boilers or into a exhaust pipe.

In FIG. 1 depicts a vertical section of hearth No. 1 according to the VG of FIG. 2; FIG. 2 is the same in AB of FIG. 3; c) 3 - a horizontal section of it along the DE c) ig. 2; FIG. 4 is the same for ZHZ FIG. 2; FIG. 5 is a vertical section of compartment No. 3 for drying sand and firing boilers according to IR in FIG. 6; FIG. b is the same for LM fig. 7; FIG. 7 is a horizontal section through 0/7 of FIG. b; FIG. 8 is the same on PC of FIG. b; FIG. 9-general location of outbreaks number 1 and department number 3.

The center (Figs. 1-4) was built with a dimple into the ground below the floor for ease of operation; therefore, in order to protect the masonry from dampness, the latter have ventilation channels 1 that enter the outside with an opening 12; space 3 in the masonry is covered with sand. A firebox is placed above the ashpit 2 with a blower door and grate, the gases from which, discharged through channels 5 from below extended, bending around pass 6 ,; passing into space 7, washing the boiler 10, with a mastic, tightly inserted into the walls of the masonry, onto a ring made of angular iron, lined with asbestos, from which: through a channel 8 to a bore to drain into a sand-drying plate or a chimney 9, regulated by flaps 13, 14.

The gases leaving from the foci No. 1, which have a sufficiently high temperature after the mastic has been boiled, pass through the window 21 into the chamber 17, the compartment No. 3 (Fig. 5-8), which is blocked from the top by a plate 18 for drying sand, and at the bottom, equipped with grate-beds 19 for laying the burning boiler so that the flame from the firebox 16 arranged with the spacing at the top penetrates the chamber 17 and washes the boiler and the iron forms placed there for firing; the fuel is placed on the grates above the ashpit 15, the gases are treated through two channels 22. discharged into the main chimney 23.

The subject of the patent. - ,.

Furnace for drying sand, firing boilers and cooking mastic, characterized with the cumulative use of: a) two identical No. 1 foci, in each of which

The fresh chimneys 5 from the firebox 4 are discharged upwards, communicating through passes 6 to the space 7 surrounding the boiler 10, which further two channels 8 are connected: a boar equipped with regulating valves; 13 and 14 for directing gases to the drying compartment sand across

channel 8-21 or into the exhaust pipe 9 and b) of compartment no. 3, covered with a plate 18 for placing sand on it and equipped for firing the boilers with a chamber 17 with grate bars 19 and a firebox 16, communicating through windows 21 with the above-indicated boils of both pockets no. one.
