It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention. It should be noted that in the description of the present invention, the terms of direction or positional relationship indicated by the terms "front", "rear", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings, which are for convenience of description only, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
Example 1:
a graphite roasting furnace capable of continuous production is shown in figure 1 and comprises a closed runway-shaped circulating track 1, a plurality of trolleys 2 for bearing graphite green bodies 4 run on the circulating track 1, and the trolleys 2 are connected end to end through a chain 22 and roll on the circulating track 1 in a circulating manner. The graphite roasting furnace also comprises two roasting furnace bodies 3, and the two roasting furnace bodies 3 are respectively arranged on the straight line edges of the runway-shaped circulating track 1.
As shown in fig. 2, the roasting furnace body 3 includes a heat-insulating casing 33, and refractory bricks 34 are provided between the heat-insulating casing 33 and the roasting chamber 31. A roasting cavity 31 built by refractory bricks 34 is arranged in the roasting furnace body 3, the section of the roasting cavity 31 is rectangular, and the circulating track 1 penetrates through the bottom of the roasting cavity 31. The circulating track 1 is provided with a groove-shaped raceway, the trolley 2 is provided with four ceramic wheels 23, and the ceramic wheels 23 roll in the groove-shaped raceway. The ceramic wheel 23 can withstand the high temperatures of firing.
As shown in fig. 3 to 4, a plurality of radially expanded firing chambers 32 are uniformly provided in the firing chamber 31, and electric heaters 35 are installed in the expanded spaces of the firing chambers 32, and the electric heaters 35 are used to heat the graphite green compacts 4 on the carts 2. The head end and the tail end of the trolley 2 are provided with heat preservation baffles 21 matched with the rectangular roasting cavity 31, the heat preservation baffles 21 take refractory bricks as bottom linings, the outer layers of the refractory bricks are wrapped with heat preservation materials, the periphery of the heat preservation baffles 21 is provided with flexible high-temperature-resistant sealing materials, the length of the trolley 2 is slightly larger than that of the roasting chamber 32, and the trolley 2 moves by the length of one trolley 2 every time, so that the heat preservation baffles 21 and the flexible high-temperature-resistant sealing materials on the heat preservation baffles are in contact with the inner wall of the roasting cavity 31 to form a sealing structure. The heat preservation baffles 21 at the two ends of the roasting furnace body 3 block the roasting cavity 31 to form a closing structure similar to a furnace door, so that heat is prevented from overflowing the roasting furnace body 3, and the consumption of electric energy is saved.
When the rapid moving trolley works, every time, the trolleys 2 connected end to end move for the length of one trolley 2.
