[0027] Refer to Figure 1 And Figure 4The bracket 12 fixedly connected to the upper surface of the load-bearing platform 16 provides a stable supporting structure for the table 13. The limiting holes 19 opened inside the bracket cooperate with the bolts 15 to accurately limit the position of the table 13 to prevent the table 13 from deflecting or shaking during use. The outer wall of the bolt 15 is threadedly connected to the inner wall of the limiting hole 19 of the bracket 12 and the table 13. By tightening the bolt 15, the table 13 can be firmly fixed to the bracket 12, ensuring that the table 13 can stably carry the clay blank during the sintering process, avoiding damage to the clay blank or uneven sintering due to the movement of the table 13, thereby ensuring the quality of the finished clay brick. One side of the outer wall of the bracket 12 is attached to one side of the outer wall of the table 13, which further enhances the stability of the table 13, so that the table 13 can better withstand the weight of the clay blank and various forces during the sintering process. The table 13 is a direct component for holding the clay blank. Its surface is flat and smooth, which can ensure that the clay blank is placed stably before sintering. At the same time, its material has good high temperature resistance and chemical stability, and will not react chemically with the clay blank, ensuring the purity and quality of the clay brick. The outer wall of the bolt 15 is set on the inner wall of the limiting hole 19. The bolt 15 is used to fix the table 13. One side of the outer wall of the bracket 12 is attached to one side of the outer wall of the table 13. The table 13 is used to hold the clay blank.
[0028] Working principle: When using the sintering furnace of the lime kiln to burn clay bricks, the limiting hole 19 opened in the bracket 12 is used, and the bracket 12 and the table 13 are screwed together by the bolt 15, so that the bolt 15 can be rotated to screw in or out of the limiting hole 19 and the threaded hole of the table 13, thereby achieving the effect of fixing and height adjustment of the table 13 on the bracket 12 to meet the requirements of placing clay blanks of different sizes and quantities. At this time, by pushing the pull rod 7, the support plate 17 and the support plate 17 thereon are connected. The effect of feeding the parts into the shell 1 is achieved. At this time, the handle 5 is turned to rotate and close the furnace door 4. At the same time, the outer wall of the furnace door 4 is tightly fitted with the outer wall of the shell 1 to ensure the sealing of the sintering furnace. At this time, the power is turned on to make the silicon carbon rod 14 start to work. At this time, a large amount of heat is generated by the silicon carbon rod 14 after power is turned on, so that the temperature in the furnace gradually increases. At the same time, since the silicon carbon rod 14 is evenly distributed on the inner wall of the shell 1, the heat can be relatively evenly spread in the furnace, so that the clay blank placed on the platen 13 is evenly distributed. The exhaust gas and water vapor are first passed through the filter screen 11 connected to the inside of the shell 1 under the action of ventilation. The filter screen 11 can filter out some impurities and dust therein, thereby achieving the effect of allowing relatively clean gas to enter the ventilation duct 2. The gas is transported to the collection box 9 through the connecting pipe 3, thereby achieving the effect of further collecting and precipitating the waste residue in the gas, preventing the waste residue and other impurities from entering the fan 10 or being discharged into the atmosphere to cause pollution and equipment damage. When it is necessary to clean the filter screen 11, the rotating block 22 is rotated to cancel the fixation of the baffle 23. At this time, the baffle 23 is opened to pull out the filter screen 11 inside the shell 1, thereby achieving the effect of cleaning the filter screen 11. When firing is completed, the furnace door 4 is opened and the pull rod 7 is pulled at the same time to achieve the effect of removing the platen 13 and the clay bricks thereon.
