[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-4This utility model provides an embodiment of a molding and drying kiln for refractory bricks, comprising a sintering furnace 1, a furnace cavity 101 inside the sintering furnace 1, the lower end of the sintering furnace 1 being fixed to a platform 2, a rectangular through groove 102 being provided between the lower middle part of the furnace cavity 101 and the upper end surface of the platform 2, and linear tracks 201 being fixedly connected to both sides of the lower middle part of the rectangular through groove 102 on the upper end surface of the platform 2, a movable platform 3 being provided at the lower end of the furnace cavity 101, and a heat-insulating support 301 being fixedly connected to the lower end of the movable platform 3 and inside the rectangular through groove 102, and two parallel support plates 302 being fixedly connected to the front and rear ends of both sides of the lower middle part of the heat-insulating support 301, with track wheels 303 rotatably connected between the two parallel support plates 302, and the heat-insulating support 301 being supported on the two linear tracks 201 by four track wheels 303 respectively, so that the heat-insulating support 301 can be rotated. The refractory bricks on the moving platform 3 move out of the furnace cavity 101 via the movement of the heat insulation support 301 along the two linear tracks 201 after the furnace door of the sintering furnace 1 is opened. This allows the refractory bricks on the moving platform 3 to be transported outside the sintering furnace 1. The track wheels 303 are rotatably connected to the two support plates 302 via rotating shafts 304. The inner sides of the two parallel support plates 302 on both sides of the lower front end of the heat insulation support 301 are fixedly connected to drive motors 305. One end of the rotating shaft 304 in the middle of the two track wheels 303 at the lower front end of the heat insulation support 301 is connected to the output shaft of the two drive motors 305 via couplings. A synchronizer is connected between the two drive motors 305. The two drive motors 305 synchronously drive the two track wheels 303 to rotate, thereby driving the heat insulation support 301 to move on the two linear tracks 201.

[0024] Please see Figure 3 and Figure 4The upper end of the moving platform 3 is connected to two middle-layer support plates 5, and the upper end of the two middle-layer support plates 5 is connected to a top-layer support plate 501. By placing refractory bricks to be sintered on the upper end of the moving platform 3, the upper end of the middle-layer support plates 5, and the upper end of the top-layer support plate 501, a large number of refractory bricks are layered to prevent accumulation from affecting the sintering quality. The front and rear ends of the upper surface of the moving platform 3 and the middle-layer support plates 5 are fixedly connected to the middle sides of the upper surface. The front and rear ends of the lower surface of the middle-layer support plates 5 and the top-layer support plate 501 are fixedly connected to the lower surface. The first threaded post 4 and the second threaded post 502 that are perpendicularly adjacent between the moving platform 3 and the middle-layer support plates 5, between the two middle-layer support plates 5, and between the middle-layer support plates 5 and the top-layer support plate 501 are all connected by a double-rotor connecting post 6. The double-rotor connecting post 6 includes a first internal threaded pipe 60. 1. The first internal threaded tube 601 is vertically disposed on the upper end of the second internal threaded tube 602. The lower end of the first internal threaded tube 601 and the upper end of the second internal threaded tube 602 are rotatably connected by a connecting shaft 603. The first internal threaded tube 601 is sleeved on the second threaded post 502 and is threadedly connected and fixed to the second threaded post 502. The second internal threaded tube 602 is sleeved on the first threaded post 4 and is threadedly connected and fixed to the first threaded post 4. By rotating the first internal threaded tube 601 and the second internal threaded tube 602 respectively, the double rotating tube connecting post 6 can be disassembled. Double rotating tube connecting posts 6 of different lengths can be replaced as needed to adjust the height between the moving platform 3 and the middle layer bearing plate 5, between the two middle layer bearing plates 5, and between the middle layer bearing plate 5 and the top layer bearing plate 501, so as to facilitate the placement of refractory bricks of different sizes.

[0025] Working Principle: During use, the refractory bricks to be sintered are placed in layers on the moving platform 3, the middle layer support plate 5, and the top layer support plate 501. During sintering, the refractory bricks undergo high-temperature treatment within the furnace cavity 101. After sintering, the furnace door of the sintering furnace 1 is opened, and the drive motor 305 is started to move the track wheel 303 along the linear track 201, causing the heat insulation support 301 to move the entire support structure out of the furnace cavity 101. At this time, the loading and unloading of refractory bricks can be conveniently carried out outside the furnace. The support plates can be quickly disassembled by rotating the double-rotor connecting column 6. The double-rotor connecting column 6 can be disassembled by rotating the first internal threaded pipe 601 and the second internal threaded pipe 602 respectively. By replacing the double-rotor connecting column 6 with different lengths as needed, the height between the moving platform 3 and the middle layer support plate 5, between the two middle layer support plates 5, and between the middle layer support plate 5 and the top layer support plate 501 can be adjusted, facilitating the placement of refractory bricks of different sizes.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
