Description

Glass kiln for burning and heating throat discharge

Technical Field

The utility model relates to a glass kiln technical field, the more specifically glass kiln of throat blowing is heated in burning that says so.

Background

When the glass kiln is put into use, molten glass liquid flows into the working part from the melting tank through the throat, is distributed into the material channel by the working part and is supplied to a feeder for use, and the discharging process in the industry is finished; in the design of the kiln structure, in order to meet the melting requirement and ensure the melting quality of glass liquid, a throat entering a working part from a melting tank is designed at the lower part of the kiln, an opening is small, and the glass liquid also needs to rise and flow into the working part after passing through the throat, so the throat is the bottleneck for the flowing of the glass liquid, the temperature of the glass kiln just fed is low, the viscosity of the glass liquid is increased along with the reduction of the temperature, the glass liquid is easy to block the throat due to the low temperature and the increase of the viscosity when passing through the throat, the glass liquid can be condensed into glass blocks when the temperature is continuously reduced, the glass liquid can not normally flow into a feeder for production, the whole feeding fails, the hardness of the glass blocks is high, the glass blocks are difficult to be processed at the throat, the glass liquid is hardened and has no conductive characteristic, the electrode cannot be used for heating, so the kiln can not be normally put into production, and the throat can be removed for re-masonry in severe cases, delay production time and cause serious enterprise loss.

Detailed Description

To make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the embodiments of the present invention are combined to clearly and completely describe the technical solution in the embodiments of the present invention, and obviously, the described embodiments are some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1 and fig. 2, the glass kiln for burning and heating throat discharge of the present embodiment is structurally configured as follows:

a feeding port 7 is arranged on one side wall of the glass kiln 1, a throat 2 is arranged at the bottom end part of the other opposite side wall, an upward and vertically bent working part channel 3 is led out from the throat 2, the tail end of the working part channel 3 is horizontally bent and divided into a first material channel 4 and a second material channel 5, and the materials are fed to a feeder through the first material channel 4 and the second material channel 5;

lie in flowing liquid hole 2 and the joining department of work portion passageway 3, enclose to establish in the kiln outside with heat-resisting brick masonry and form combustion chamber 8, insert on the diapire of combustion chamber 8 and perisporium several gas flame projecting guns 9 that stretch into indoorly at the interval, the shower nozzle of each gas flame projecting gun 9 sets up towards flowing liquid hole 2 and the joining department of work portion passageway 3 with closing on, the high-pressure hose 10 of each gas flame projecting gun 9 collects to the pipe end of main air supply pipe 11, be connected to the air supply air feed through main air supply pipe 11, be equipped with gas flow control valve 12 on each high-pressure hose 10 respectively, be equipped with ooff valve 13 on the main air supply pipe 11.

In practice, the main gas supply pipe 11 may be connected to an on-site gas source, or a separate gas storage tank may be separately provided to supply gas to each gas burner 9.

In the embodiment, as shown in fig. 2, the outer frame of the gas chamber is in a cuboid structure and is arranged around the liquid flowing hole 2 and the lower end part of the working part channel 3; two gas flame guns 9 are inserted on the bottom wall of the gas chamber, and the spray heads are upward and face the bottom of the liquid flowing hole 2; two gas flame guns 9 are inserted into the peripheral wall of the gas chamber, and the nozzles transversely face the side wall of the lower end part of the working part channel 3.

The preferred refractory brick is made of high-alumina brick or mullite brick, the melting point of the refractory brick is more than 1500 ℃ and higher than 800 ℃ of the glass block, and the refractory brick has good thermal shock resistance and heat preservation effect.

The gas quantity can be adjusted by each gas flow adjusting valve 12, and when the method is implemented, the outer wall of the throat 2 in the combustion chamber 8 can be heated to 1000-1100 ℃ by each gas flame gun 9, and the temperature is higher than the melting point of the glass blocks, so that the condensed glass blocks in the throat 2 are melted into glass liquid, and the glass liquid can smoothly flow from the throat 2 to the working part channel 3.

When a new kiln is put into operation, glass raw materials are put into the kiln from the feeding port 7 and melted in the melting tank 6, and along with the increase of glass liquid, the glass liquid can enter the working part channel 3 through the throat 2 and then redistribute the material channel I4 and the material channel II 5 to be supplied to a feeder.

And in the process that the glass liquid enters the working part channel 3 from the melting tank 6 through the throat 2, the throat 2 is blocked by the glass liquid due to the narrow space and the low temperature at the throat 2, if the temperature is continuously reduced, the glass liquid is condensed into glass blocks to block the throat 2, and the hardness of the glass blocks is very high, so that the difficulty of dismantling is high.

In order to prevent the above situation, in the embodiment, the combustion chamber 8 is additionally provided and a plurality of gas flame guns 9 facing the joint of the throat 2 and the working part channel 3 are arranged, the outer wall of the position is heated by the gas flame guns 9, the refractory bricks on the outer wall of the heated throat 2 conduct heat to the internal molten glass or the condensed glass blocks, so that the glass blocks are melted into molten glass, and the molten glass smoothly circulates at the position and enters the working part channel 3 through the throat 2.

While embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that: various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
