Abstract

The utility model relates to a glass melting furnace flue bottom plate, including concrete floor (1), be equipped with spaced chamotte brick bar buttress (4b) on concrete floor (1), form heat dissipation channel (5) and communicate with each other with the atmosphere between the adjacent chamotte brick bar buttress (4b), lay chamotte brick bottom plate layer (4a) again on chamotte brick bar buttress (4b), lay insulating brick layer (3) on the chamotte brick bottom plate layer (4a) again, lay chamotte brick layer (4) on insulating brick layer (3). The utility model has the advantages of: because increased air heat dissipation channel layer between flue bottom plate and the concrete floor, the circulation of air has weakened the heat transfer of flue -gas temperature to the concrete greatly to guaranteed that the concrete floor is in below the reasonable temperature.

Description

A kind of glass melter flue base plate

technical field:

The utility model relates to glass melter, and particularly a kind of flue base plate overhead heat insulation in field built by laying bricks or stones by glass melter flue structure.

background technology:

Glass melter is built by laying bricks or stones in the concrete melt pit that image space ship shape is the same, and regenerator and flue directly carry out building by laying bricks or stones (see accompanying drawing 1) on concrete floor.The flue-gas temperature of regenerator bottom is sometimes up to 600 ~ 700 DEG C, and the flue-gas temperature in flue also reaches 400 ~ 600 DEG C.Heat resisting temperature due to normal concrete is no more than 200 DEG C, must prevent the high temperature of flue gas from causing cracking and the efflorescence of concrete floor during design, usual method of design is all that concrete floor adopts heat resistance concrete, then on heat resistance concrete base plate, lay multilayer common brick add insulating brick, use clay brick near fume side, three kinds of bricks superpose in order to isolated flue gas to concrete heat transfer.If it is on the low side that the number of plies laid by common brick, insulating brick, clay brick, concrete floor will be subject to Thermal cracking or efflorescence, causes Groundwater infiltration, has a strong impact on production; If common brick, insulating brick, clay brick are laid, the number of plies is a lot, and one side increases cost, adds the load of concrete floor, and under flue base plate central zone, surface concrete still can be in hot environment on the other hand.

utility model content:

A kind of glass melter flue base plate, comprise concrete floor, it is characterized in that: on concrete floor, first establish spaced clay brick bar shaped to pile up neatly, form heat dissipation channel between adjacent clay brick bar shaped buttress to communicate with air, clay brick backplane level is re-layed on clay brick bar shaped buttress, clay brick backplane level re-lays heat insulation brick layer, heat insulation brick layer lays undercloak near fume side.

The utility model has the advantage of: due to flue base plate and and concrete floor between add air heat dissipation channel layer, the circulation of air reduces flue-gas temperature greatly to concrete heat transfer, thus ensure that concrete floor is in below rational temperature.

accompanying drawing illustrates:

Fig. 1 is existing glass melter flue base arrangement;

Fig. 2 is glass melter flue base arrangement of the present utility model.

Embodiment

A kind of glass melter flue base plate that the utility model provides, comprise concrete floor 1, first concrete floor 1 is provided with the clay brick bar shaped buttress 4b of one group of fixed spacing, form heat dissipation channel 5 between adjacent clay brick bar shaped buttress 4b to communicate with the air outside melting furnaces, clay brick backplane level 4a is re-layed on clay brick bar shaped buttress 4b, clay brick backplane level 4a re-lays the heat insulation brick layer 3 of clay, the heat insulation brick layer 3 of clay continues to use clay brick layer by layer 4 near fume side.Described clay brick adopts siliceous clay brick.

Due to flue base plate and and concrete floor between add air heat dissipating layer, the circulation of air reduces flue-gas temperature greatly to concrete heat transfer, thus ensure that concrete floor is in below rational temperature.

Claims

1. a glass melter flue base plate, comprise concrete floor (1), it is characterized in that: on concrete floor (1), establish spaced clay brick bar shaped to pile up neatly (4b), form heat dissipation channel (5) between adjacent clay brick bar shaped buttress (4b) and communicate with air, clay brick backplane level (4a) is re-layed on clay brick bar shaped buttress (4b), clay brick backplane level (4a) re-lays heat insulation brick layer (3), heat insulation brick layer (3) is laid undercloak (4).
