SU30816A1 - Device for heating the feeder channel with glass melting baths - Google Patents

Description

The invention aims at ensuring the temperature of the glass flowing through the feeder channel and eliminating the hardening of the outside air, for which the feeder channel is enclosed in a special chamber with insulated walls, forming channels on the sides and below the feeder that communicate with the main boron; in order to remove glass that might leak if leaked — into the under-ground channels, pockets with hydraulic valves are arranged; An annular chamber with a tangentially located nozzle was used to eliminate the intake of air through the hole for the feeder dive.

In FIG. 1 shows a vertical longitudinal section of a device for heating the feeding channel; FIG. 2, sections 45 and CD of FIG. one; | FIG. 3- section EF of FIG. -one.

In the proposed device, the feeder channel of 3 okruzhek chamber, the side walls 2 of which are sealed with isolation /. Between the walls 2 of the chamber and j the side walls / (of the feeder channel, I, as well as between the bottom 11 of the latter and the bottom of the chamber 14, channels 8a and 9 are formed. The hot gases of the burners 5 j or from the furnace 6, regulated by a pinch 7, or from both sources at the same time, wash from above the feed channel 8 and

(five)

forcibly directed down the vertical channel, which is regulated by the drawers 8, behind and under the pallet 9, and is heated outside the wall o and the bottom of the feeder channel. A nozzle / 5 is connected to the bottom of J4 to discharge gases into the main bore 17, through lined nozzles 16 with an adjusting valve 15. The nozzles / 5 simultaneously serve to release the glass that can penetrate through the cracks in the feeder channel 3 equipped with hydraulic gates 35 and partitions to bottom; Underwater accumulating glass is discharged from pockets without compromising shutter tightness. To eliminate the flow of glass at the point of attachment to the channel 3 of the bow of the bowl 4, this is filled in a pzz. After a layer of magnesium oxide packing, pressing / pressing the bowl 4 to the channel 3 with screws 36, bar 20 and sliding refractory plate 38.

To protect against suction of cold air, through the opening 27 for the feeder dive 28, a ring-shaped chamber 30 is installed on the lid 29, heated by a tangential nozzle 31, the flame of which flushes the walls of the chamber 30, fills the opening 27, slides down the surface of the dive 28. D preventing suckers through the seam of the cap 29 above the nasal cup 4, as well as through the seams of the stream 32, which are compacted with sand poured into detached removable superstructures 33 and 34 of the casing. The subject matter of the invention. 1. A device for heating the feeder channel with glass-melting baths, characterized in that, in order to ensure the temperature of the glass flowing to the outlet hole in its entire thickness and to eliminate external air suction, the feeder channel is enclosed in a special chamber with sealed walls of insulation 7 2, forming lateral and pallet channels 8a and 9, which are inserted into the main bypass bars 77. 2. In the device according to claim 1 a device for eliminating the intake of external air through the opening 27 for the feeder dive, with annular chamber 30, the heated nozzle disposed tangentially. 3. In the apparatus according to claim 1, use pockets 13 located under the nozzles with hydraulic gates 55, which serve to scoop out the glass flowing from the furnace.
