SU19121A1 - Chamber brick kiln with dryer - Google Patents

Description

The proposed furnace consists of nine (or other number) chambers, has two shmouh-channels, one of which communicates with the upper parts of the chambers, from the other in each chamber there are two branches down into a separate longitudinal channel for each chamber, which branches out The four channels that open in the side walls of the fire chambers - Cameras communicate with each other directly through the bottom channels. The dryer is located next to the furnace at the level of the chamber arches; for the inflow of hot air into it there is a profile channel, the processes of which are connected by extension sleeves to openings in the center of the chamber arches; the channel engages in the annular space surrounding the bottom of the stack and communicates with a second longitudinal channel, the processes of which open into each compartment of the drying room in the middle of its ceiling. The exhaust air goes into the chimney through the lattice under the dryer through the channel.

The location of the proposed chamber dryer next to the kiln and transportation of raw material from the press to the dryer and from it to the oven, according to the inventor, makes it possible, when setting up a continuous flow, to bake for a whole year,

increase the productivity of the furnace irn a small cost of the device last.

In FIG. 1 shows a cross section of a kiln with a dryer according to 1-1 of FIG. 2 and 3; FIG. 2 is a longitudinal section of the first chamber of the furnace. Through -A, the second chamber along B-8, the third chamber along (7-C, the fourth and ninth chambers according to DD, the fifth chamber along E-K, the sixth, seventh and eighth chambers along FF; Fig. 3 is a top sectional view of the furnace: the first chamber of 1-1, the second chamber of 2-2, the third chamber of 3-3, the fourth chamber of 4-4, the fifth chamber of 5-5, pole, the seventh, eighth, ninth chambers of the drying chamber C, C (;, Sc 6-6, the drying chamber d 5-5 and the drying chamber C, € and Cj 8 - 8 of Fig. 1, and Fig. 4 - section 7-7, 8-8 of Fig. 1.

The furnace consists of nine identical, partitioned off walls with a tiltable chamber thrown back (fig. 1-3), covered with a roof o, with one hole in each chamber with a lid closed; each chamber is equipped with three fire chambers, with grate bars and ashpit; from above, in the walls of the furnace, for all nine chambers and two shmouh-channels d in the front wall and e-internal (Fig. 1 and 2-chamber 2 and Fig. 3 - chamber 5); these

The channels communicate and separate with each chamber using cones and are designed to transfer hot air through them from the chambers in which the burnt brick is cooled. In the front wall of each chamber from channel d vertically downward two channels x (Fig. 2, chamber 2, Fig. 3, chamber 4-5), communicated with a horizontal channel, from which three channels, ok, separated by valves, They then go horizontally and branch into four canals and, wrapping each firebox r, from two sides, between the interlocks of the burnout exit of each firebox, have outlet ports Ж4-. Each chamber for transmitting fire to a subsequent chamber has M flaps in the bottom between the chamber wall (Fig. 2 and Fig. 3 Chambers 2), which passes into the vertical channel I (Fig. 2, camera 2 and Fig. 3, camera 1) and horizontal channel I and out through three holes Wg into the next chamber (Fig. 2, chamber 2 and Fig. 3, chamber 3); The HI channel is uncoupled by a cone. The transfer of gas from the chamber 9 into the chamber 1 occurs through the channel A (Fig. 1 and 2 chambers 4 and 9 and Fig. 3, chambers 1 and 9); for loading and unloading in each chamber there is a door L. Over the entire furnace, in front of the fireboxes, a stoker L / is built in the ground and is overlapped on top of the ground by the ceiling / D above case O. Each chamber has an outlet pipe n, closed with a cone P and communicating with the common flue from a sheet iron pipe. The cables from the cones of the channels, for ease of operation, are led to the stoker and equipped with counterweights or connected to the levers.

The dryer is located on the ground level behind the rear wall of the furnace and consists of seven, also located in a straight line with casing, O) -St chambers sheathed inside with roofing iron, the capacity of each chamber is equal to half the capacity of the furnace chamber, the doors Sa and Sa of each chamber serve for loading and unloading dried raw. Dry warm air enters each chamber from above through a sleeve m, which communicates with channel Y, which in turn communicates with an air brick chamber, in the center of which an iron pipe P passes; air enters chamber f from below from channel X, which has overheads X with a retractable iron sleeve Xz above each chamber, through which, when connected with a drain channel (Fig. 4 and 3 chambers 6 and 7), air passes through a heated, baked brick, goes through sleeves Xg, appendix Xi, duct 1, chamber f, duct) and sleeves t to the top of the dryer and is removed, saturated in pairs, from the bottom through the bottom grid, collecting chamber 4i, duct Ч2 to the chimney.

The raw material is transported by a continuous stream from presses and (Fig. 3) through the belt into the drying chamber, and from the latter also along the belt into the furnace, on the opposite side of the dryer, along the passageway and the corridor o. The ribbon for feeding raw material from the drying chamber into the furnace chamber has a slope, as a result of which there is no need for energy expenditure.

The subject of the patent.

A chamber brick / kiln furnace with a dryer, characterized in that for conducting hot air from the cooling chambers to the fireboxes of the other chambers, the vertical channels oy, two for each chamber, opening into the horizontal channel Ж; from which the number of fuel cells in the chamber moves downwards, three channels, separated below into transverse channels with OKt openings in the side walls of the fireboxes, is to supply the same heated air to the compartments Ci, Cz, Cg .. .. With dryer served ny X and Y channels above the furnace communicating: with one another, through the surrounding lower part of the chimney chamber Q, with the furnace chamber through-processes X, and with openings in ceilings compartments through processes sushilni- m.
