Description

The invention relates to mobile devices for suctioning air through the charging ports of the cooling chamber of a calcined product and injecting it into the air channel of the ring furnace.

In the known systems for cooling annular tubes and the use of hot air, the latter is very complicated because of the fact that the furnace itself is used as a moving element. By virtue of this, the air passes through: an open walker of the furnace, a cooling zone of the fired product and further, depending on the system used, a single fuel pipe and a portable duct, either a loose build or an ochalkovy system. In one of these three methods, heated air is transferred to the so-called biail channel, and from there to the drying chambers.

The heated air is extracted from the suction chamber from the chamber with the help of a special separate fan installed at the top of the furnace.

The peculiarity of the described device is that it consists of a fan with an electric motor and suction nozzles adjoining to the fuel-loading openings of the cooled chamber, which are connected to the collector near the fan itself, and from the outlet hose adjacent to the free. end to the corresponding air channel hatch, corresponding to the cooled part of the furnace, and the installed trolley. but the whole furnace along rail tracks, with or without a relief, is laid above the kiln baking channel and throughout its passage.

FIG. A device is shown for regulating the cooling process in annular kilns in cross section along A-A in FIG. 2; in fig. 2 is a top view.

The device is mounted on a platform trolley, moving over the kiln firing channel of the furnace through all of its run along rails 7 or without rails.

On the cart mounted fan 2 with a motor. A collector 4 is attached to the fan, to which are attached the suction nozzles 3, which are connected to the charging and loading openings of the cooled section of the furnace channel.

The outlet side of the fan otvodpv1m sleeve 5 hot air is connected to the hatch of the air channel. With a large length, the discharge sleeve has intermediate roller supports 6.

The application of the proposed device not only provides a significant increase in vacuum in the chamber with a corresponding acceleration ef: cooling and with the improvement of the working conditions of the landowners, but also obsh, its improvement in the operation of the whole furnace, expressed in the fact that the air duct will work under the pressure of the air supplied by the installation, due to which its traction device is unloaded from the need for air suction, and the firing process will occur under the action of the air pressure from the air channel with tem, which should help to accelerate the movement of AGN in the furnace, and hence increase its performance.

Subject invention

Mobile unit for adjusting the cooling process in ring kilns for firing building materials, characterized in that it consists of a fan mounted on a trolley moving throughout the kiln above the kiln channel and provided with suction nozzles attached to the fuel charging openings of the section to be cooled the furnace channel and the outlet sleeve attached to the hatch of the air channel corresponding to the cooled part of the furnace.
