[0004] The technical scheme of the utility model is: it includes a tunnel kiln composed of a kiln steel structure, a kiln wall, a kiln roof and a heating device, a kiln car and an automatic control device, a track is set on the outer side of the kiln roof of the kiln walls on both sides, and a curved sealing groove is set on the end face of the kiln roof brick. The kiln car is composed of wheels, axles, a kiln car loading platform, a crucible for holding materials and a heat-insulating seal. The kiln car loading platform is made of a square metal frame structure filled with heat-insulating materials. The axles are fixedly installed at both ends of the kiln car loading platform through bearing brackets. The wheels are installed at both ends of the axles and placed on the track set on the kiln roof. A circular hole for placing the crucible is set in the middle of the kiln car loading platform, and heat-insulating seals are set on the bottom surfaces of both sides. The lower end surface of the heat-insulating seal is set with a curved sealing platform that matches the kiln roof curved sealing groove. The crucible is made of heat-resistant steel with excellent thermal conductivity and uniform thickness. The outer edge of the mouth is provided with a fixed flange that matches the circular hole in the middle of the kiln car loading platform, and a sealing gasket is set around the crucible fixing flange and the circular hole of the kiln car loading platform.

[0005] The utility model has the following beneficial effects: since the crucible kiln car can run continuously on the track, it can be heated continuously, greatly improving production efficiency, and recovering part of the heat energy at the same time. It has the advantages of reasonable structure, energy saving and efficiency improvement, simple operation, safe operation, etc., and can be widely used in various crucible continuous production thermal equipment.

[0006] The utility model will be further described below in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0014] like Figure 1 As shown, the crucible kiln car includes a tunnel kiln consisting of a kiln steel structure 1, kiln walls 2, kiln roof 3 and a heating device, a kiln car and an automatic control device. Tracks 5 are arranged on the outside of the kiln roof 3 of the kiln walls 2 on both sides, and curved sealing grooves are arranged on the end faces of the kiln roof bricks. Figure 2 , Figure 3 , Figure 4 As shown, the kiln car is composed of wheels 6, axles 7, a kiln car loading platform 8, heat-insulating seals 9 and a crucible 11 for holding materials. The kiln car loading platform 8 is a square metal frame structure filled with heat-insulating materials. The axles 7 are fixedly mounted on both ends of the kiln car loading platform 8 through bearing brackets. The wheels 6 are mounted on both ends of the axles 7 and placed on the tracks 5 set on the kiln roof. The wheels 6 can slide on the tracks 5. A circular hole 14 for placing the crucible 11 is set in the middle of the kiln car loading platform 8, heat-insulating seals 9 are set on the bottom surfaces of both sides, and a curved sealing platform 13 that matches the curved sealing groove on the kiln roof is set on the lower end surface of the heat-insulating seal 9. As shown Figure 5 , Figure 6 As shown, the crucible 11 is made of heat-resistant steel with excellent thermal conductivity and uniform thickness. The outer edge of the mouth is provided with a fixed flange 12 that matches the middle circular hole of the kiln car loading platform 8. The crucible fixing flange 12 and the circular hole of the kiln car loading platform are provided with a sealing gasket 10. At the same time, sand sealing grooves can be provided on the insulation walls on both sides to further strengthen the sealing of the heating space. When the utility model is implemented, the furnace 4 is heated by the combustion device arranged on both sides of the kiln wall 2 to calcine the material in the crucible 11. Since the crucible 11 is fixed on the kiln car loading platform 8, the kiln car continuously advances on the tracks 5 on both sides of the kiln roof 3 through the wheels 6. The furnace 4 is heated by the combustion device arranged on both sides of the kiln wall 2, and the material in the crucible 11 can be continuously calcined, thereby ensuring that the material can be produced continuously. The utility model has the advantages of reasonable structure, simple operation, safe operation, energy saving and efficiency improvement, etc., can significantly improve production efficiency, and can be widely used in various crucible calcining equipment.
