[0002] Cement industry is one of the most energy-intensive industries in the world, its energy consumption accounts for about 70%-80% of the total energy consumption of building materials industry in China, and the coal consumption for burning clinker accounts for about 6% of the total coal consumption in China. With the continuous development of economy, in the long run, energy prices will continue to rise, and the production cost of cement will also increase with the increase of energy prices, and the cement kiln collaborative disposal of alternative fuels will become a trend.

[0003] At present, the alternative fuels mainly used by domestic cement industry for rotary kiln treatment are refuse derived fuel (RDF) and part of hazardous waste, and the hot disc furnace is the best solution at present. The alternative fuels are first incinerated in the rotary disc furnace, and the generated flue gas and residue enter the decomposition furnace, and the rotary disc furnace and the decomposition furnace form an integral whole, the inside is cast with refractory insulation material, and the bottom is a rotary furnace disc. Dangerous waste (liquid or solid) or various garbage and part of the third air enter the rotary disc furnace for full combustion. The whole combustion process occurs in the rotary disc furnace, which fully reduces the impact of alternative fuel combustion on the decomposition furnace.

[0004] Because the materials above the rotary disc are burning, the temperature in the furnace is very high, and some gases produced by combustion will produce toxic and harmful gases. The transmission device is arranged below the rotary disc, and the transmission device needs to work at room temperature, and personnel also need to enter the lower shell for maintenance, so a sealing device needs to be arranged between the rotary disc and the shell to prevent high-temperature gas in the furnace from passing to the lower part of the rotary disc, thereby ensuring the normal operation of the equipment and the safety of personnel.

[0005] Based on the above problems, the utility model provides a sealing structure of hot disc furnace. UTILITY MODEL CONTENT

[0007] Technical scheme: the utility model provides a sealing structure of hot disc furnace, which comprises a shell and a rotary disc, the rotary disc is provided with an upper sealing ring below through a bolt pair, the shell is provided with a lower sealing groove fixedly installed below the upper sealing ring, the shell is provided with a liquid supplementing device matched with the lower sealing groove, the liquid supplementing device is provided with a communication pipe connected with the lower sealing groove.

[0008] The sealing liquid is water or a non-combustible liquid.

[0009] The liquid supplement device is composed of a tank body, a floating ball valve and a liquid storage tank, the tank body is communicated with the communicating pipe, the liquid storage tank is installed on the tank body, the floating ball valve is installed below the liquid storage tank, and the tank body is installed on the shell.

[0010] Compared with the prior art, the sealing structure of the hot plate furnace has the advantages that: 1. The structure is simple to install and maintain, safe and reliable, and can isolate the high-temperature gas in the hot plate furnace from the lower side of the rotating disc, thereby ensuring the normal operation of the equipment and the safety of personnel; 2. When the liquid level of the sealing liquid drops, the floating ball valve is automatically opened, and the sealing liquid in the liquid storage tank can be automatically supplemented into the lower sealing groove, so that the staff only needs to supplement the sealing liquid into the liquid storage tank regularly, and the sealing control is convenient.
