Problems solved by technology

The existing silicon carbide production technology cannot safely extract the gas in the smelting furnace to achieve the purpose of gas collection and negative pressure smelting
On the one hand, a large amount of CO gas is burned on the surface of the smelting furnace to form CO 2 Direct discharge into the atmosphere not only wastes resources but also increases carbon emissions, and cannot meet the production requirements of energy saving, emission reduction, low-carbon and environmental protection. On the other hand, it cannot realize negative pressure smelting to reduce power consumption of products

Embodiment 1

[0046] Such as figure 1 , figure 2 , image 3 Shown, make accessory (16), and accessory (16) comprises sealing chamber (3), seepage water tank (4), sealing plate (5), material blocking plate (6). Permeate holes (7) are opened on the permeate water tank (4) to communicate with the sealed cavity (3). Open the mounting hole (8) on the accessory to install the accessory (16) on the masonry (2).

[0047] Such as Figure 4 As shown, after the accessory (16) is installed on the masonry (2), start to assemble and make the side wall (14) with the sealing plate (5) and the material blocking plate (6), after the side wall (14) is installed, the Temporary baffle plate (9) puts the position shown in the figure, and begins to fill furnace charge (12). After filling the charge (12), soak the wall of the sealing cavity (3) with water, fill the sealing paste (3) after soaking, fix the sealing paste (3) so that it does not "flow", and prevent the sealing paste (3) from drying out . Plac...

Abstract

The invention provides an end wall of a silicon carbide smelting furnace, and in particular relates to an end wall which can be used for realizing cheap, convenient and reliable sealing between the end wall and a side wall so as to safely extract gas from a furnace and is used for solving the problem that the slit between the end wall and the side wall is difficult to seal due to the unreasonable structure of the end wall in the existing silicon carbide smelting technology. In the invention, a brickwork (2) is equipped with an enclosure (16) containing a seal cavity (3) and a seal plate (5), wherein seal paste (3) is filled in the seal cavity (3); and the brickwork (2) is hermetically and the seal plate (5) are pasted into a whole through the seal paste (3) so as to realize sealing between the end wall and the side wall (14). The end wall provided by the invention is used for sealing the slit between the end wall and the side wall so as to extract the gas in the silicon carbide smelting furnace; and the end wall has the advantages of simple fabrication method, low cost, high safety and high reliability, and is simple, convenient and feasible in operation.

Description

technical field [0001] The invention belongs to the technical field of silicon carbide smelting, and relates to a smelting furnace end wall for realizing the sealing between the end wall and the side wall when the gas in the silicon carbide smelting furnace is pumped out of the furnace. Background technique [0002] The silicon carbide smelting furnace is composed of end wall, side wall and hearth. The existing silicon carbide production technology cannot safely extract the gas in the smelting furnace to achieve the purpose of gas collection and negative pressure smelting. On the one hand, a large amount of CO gas is burned on the surface of the smelting furnace to form CO 2 Direct discharge into the atmosphere not only wastes resources but also increases carbon emissions, and cannot meet the production requirements of energy saving, emission reduction, low-carbon and environmental protection. On the other hand, it cannot realize negative pressure smelting and reduce power ...
