Description

The smoke generator is known, the contents of the housing, the hopper for sawdust, the smoke chamber with the grate 5, the ash chamber with the air supply collector and the cylindrical smoke duct 11).

The disadvantage is that it creates stagnant zones with volatile gases, which, in contact with glowing sawdust, erupt, creating dangerous working conditions for the staff, as well as interruptions in smoke supply. 15

Another disadvantage is the unevenness of sawdust smoldering over the entire area of the grate due to the unequal air flow rate that comes through the ash chamber through the flap. This leads to unstable operation of the smoke generator and ·. Changing the temperature of the exhaust smoke.

The aim of the invention is to stabilize the process of smoke formation, to ensure safe working conditions for the service person / · la.

This is achieved by the fact that the smoke generator is supplied with an additional smoke

a house made in the form of a ring, located in the upper part on the outer side of the chambered chamber and communicated with it through windows, while in the upper part of the smoke chamber along its inner perimeter reinforced cone-shaped partitions to separate the flow of smoke, and the collector of air supply in the ash chamber It is a coaxially located torus with openings in the upper part of the inner and outer sides, with a visor reinforced around the perimeter of the torus.

FIG. 1 shows the device, vertical ticking in FIG. 2 - section A — A in FIG. 1.

The smoke generator consists of a housing 1 and a fixed grate, ki 2. The upper part of the smoke generator housing is separated by a disk-bottom 4 fixed on a rotating shaft 3 to form a hopper 5 for sawdust. The disk 4 has a cutout, for example in the shape of a truncated segment (FIG. 2), to which a dispenser 6 is attached to the bottom, somewhat expanding downwards to prevent the occurrence of sawdust. The lower edges of the walls of the dispenser have

at some distance from the grate 2.

The cavity between the rotating bottom 4 and the grate 2 forms a smoke generation chamber 7. In the upper part of the chamber 7 smoke formations __

8 cone-shaped partitions are added **

molds made of 'sheet steel with inclined parts''a''and''6 ¹ '

At the top of the chamber 7 Dymbobra-ιе, under the disk 4 in the body of the body ·

1, along its entire circumference, a series of Windows 9 (Figs. 1, 2) / connecting the chamber 7 are performed using Yus pipes, / a cavity of an external annular duct 11. From here smoke is discharged through pipes 12 for cleaning. 15

By axis of the housing 1 is mounted in the smoke chamber of the cylinder-flue 13 with windows 14, the latest reports from the purification chamber 15 and the smoke removal to smokehouse assemblies (in figures ^20: rah not shown).

Between the grate 2 and the bottom 16 of the housing 1, an ash chamber 17 is formed, in which the air supply collector 18 is installed, does it represent? 25 A coaxially located torus. The collector 18 has on top at least two rows of holes 19 located on both sides of the axis of symmetry of the torus. On top of the collector 18 „

fortified visor 20 (FIG. 1), vypolnen- = ⁰ ny shaped plate intended for a more uniform distribution of the air jets under the grate 2 and prevent clogging of the ash and the sawdust openings 19.

The housing 1 of the smoke generator is equipped with a water jacket 21.

The smoke generator works as follows. 40

From the bunker 5, the bottom of which is a rotating disk 4, sawdust through the dispenser 6 enters the grate 2, where the blown air is blown through the opening 19 of collector 18 and smolders, forming a smoke-air mixture in chamber 7.

The jets of air, striking the visor 20, are more evenly distributed over the entire area of the grate 2, and the burnt (and unburned) sawdust particles are fed to the visor and blown off from it to the ash chamber without clogging the holes 19,

Installed in the chamber 7, the partition 8 of the conical shape direct

on the inclined part ¹ 4 "", smoke flows to the windows 14 of the cylinder-DYMOVOD 13, and on the inclined part '' 6 '' - to the windows 9 of the outer additional ring Guo of the duct 11. Then the smoke comes from the ducts 13 and 11 into the common chamber for cleaning of suspended particles and then goes to the smoke chamber (not proven in the figures). Due to this, stagnant zones are eliminated in the smoke generation chamber, which contributes to a stable process, eliminates the conditions for spontaneous combustion of sawdust, establishes a constant smoke temperature and improves its quality.

The smoke generator can be used in the fish and food industries to produce smoke used in the production process.

The positive effect is that the taper-shaped partitions installed in the smoke chamber prevent the sawdust from drying out in the bunker, which also contributes to the stability of work and the improvement of the quality of smoke during smoldering sawdust.
