This involves removing the ceramic fiber aerogel insulation plug from a pre-drilled slot, then rotating the high-temperature resistant ceramic bolt to separate its end from the first threaded hole. The ceramic fiber aerogel insulation module can then be removed from the insert for replacement. This allows for rapid, localized replacement and repair of the ceramic fiber aerogel insulation module, solving the problem of slow repair after insulation layer damage.

[0006] To address the existing technical problems, this application provides a modular fiber cotton insert-type high-temperature kiln structure, including a furnace body, an insulation layer disposed inside the furnace body, a heating wire disposed inside the furnace body, a movable sealing mechanism disposed on one side of the furnace body, and a support mechanism disposed at the bottom of the furnace body. A ceramic fiber aerogel pad is fixed on the inner wall of the furnace body. The inner wall of the furnace body is evenly distributed with several insertion rods that can penetrate the ceramic fiber aerogel pad, and the end of the insertion rod away from the furnace body is provided with a first threaded hole. The insulation layer includes several ceramic fiber aerogel insulation modules, and several protrusions are evenly distributed on the edges of the ceramic fiber aerogel insulation modules. A pre-reserved groove is provided on one side of the ceramic fiber aerogel insulation module, and an insertion hole is provided at the center of the pre-reserved groove so that it can be fitted onto the insertion rod. A high-temperature resistant ceramic bolt is installed in the reserved slot. One end of the high-temperature resistant ceramic bolt can be installed in the first threaded hole, and the end of the high-temperature resistant ceramic bolt is threadedly engaged with the first threaded hole.

[0007] As one technical solution of this application, the insulation layer further includes ceramic fiber aerogel heat insulation plugs, which can be installed in the reserved groove.

The sealing mechanism includes a furnace door, a refractory base plate is fixed to the upper surface of one side of the furnace door, and a roller capable of moving along the first limiting groove is installed on one side of the bottom of the furnace door. The support mechanism includes a horizontally movable seat, the top of which is fixedly connected to the bottom of the furnace door on the side away from the rollers.

[0009] As a technical solution of this application, the support mechanism further includes a first support frame, which is located below the furnace bottom plate. The two sides of one end of the first support frame are fixed to the inner wall of the furnace body. The two sides of the top of the first support frame are symmetrically provided with second limiting grooves, and slide rails are horizontally fixed on the inner walls of the two sides of the first support frame. The bottom of the movable seat is equipped with rollers that can travel along the second limiting groove, and the two sides of the movable seat are symmetrically provided with sliding grooves that can slide and cooperate with the slide rail.

[0023] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments. See Figures 1-8 As shown, a modular fiber cotton insert-type high-temperature kiln structure includes a furnace body 1, an insulation layer 4 disposed inside the furnace body 1, a heating wire 5 disposed inside the furnace body 1, a movable sealing mechanism 3 disposed on one side of the furnace body 1, and a support mechanism 2 disposed at the bottom of the furnace body 1. A ceramic fiber aerogel pad 8 is fixed on the inner wall of the furnace body 1. The inner wall of the furnace body 1 is evenly distributed with several insertion rods 12 that can penetrate the ceramic fiber aerogel pad 8. The end of the insertion rod 12 away from the furnace body 1 is provided with a first threaded hole 13. The insulation layer 4 includes several ceramic fiber aerogel insulation modules 41, and several protrusions 411 are evenly distributed on the edge of the ceramic fiber aerogel insulation modules 41. A reserved groove 412 is provided on one side of the ceramic fiber aerogel insulation module 41, and an insertion hole 413 that can be sleeved on the insertion rod 12 is provided at the center of the reserved groove 412. A high-temperature resistant ceramic bolt 43 is provided in the reserved groove 412. One end of the high-temperature resistant ceramic bolt 43 can be installed in the first threaded hole 13, and the end of the high-temperature resistant ceramic bolt 43 is threadedly engaged with the first threaded hole 13.

[0024] By fixing several protrusions 411 at the edge of the ceramic fiber aerogel insulation module 41, multiple ceramic fiber aerogel insulation modules 41 can be spliced ​​together to form a complete insulation layer 4. By fixing the ceramic fiber aerogel pad 8 on the inner wall of the furnace body 1, heat energy is prevented from baking the inner wall of the furnace body 1 through the splicing points of the ceramic fiber aerogel insulation modules 41, thus preventing excessive heat loss and improving the insulation effect of the high-temperature kiln. When the insulation layer 4 is damaged, the ceramic fiber aerogel insulation plug 42 is removed from the reserved groove 412, and then the high-temperature resistant ceramic bolt 43 is rotated to separate the end of the high-temperature resistant ceramic bolt 43 from the first threaded hole 13. Then, the ceramic fiber aerogel insulation module 41 can be removed from the insertion rod 12 for replacement. This enables rapid replacement and repair of localized parts of the ceramic fiber aerogel insulation module 41, solving the problem of the inability to quickly repair damaged insulation layer 4.

[0025] See Figure 5 and Figure 6 As shown, the insulation layer 4 also includes a ceramic fiber aerogel insulation plug 42, which can be installed in the reserved groove 412.

[0026] By installing the ceramic fiber aerogel heat insulation plug 42 in the reserved groove 412, the ceramic fiber aerogel heat insulation plug 42 is located on one side of the high temperature resistant ceramic bolt 43. The ceramic fiber aerogel heat insulation plug 42 blocks the high temperature from directly baking the high temperature resistant ceramic bolt 43, thereby avoiding damage to the high temperature resistant ceramic bolt 43 caused by high temperature baking, and thus improving the service life of the high temperature resistant ceramic bolt 43.

[0027] See Figure 1 and Figure 4 As shown, a furnace bottom plate 11 is horizontally fixed inside the furnace body 1 below the insulation layer 4, and first limiting grooves 111 are symmetrically opened on both sides of the upper surface of the furnace bottom plate 11. The sealing mechanism 3 includes a furnace door 31, a refractory base plate 312 fixed on the upper surface of one side of the furnace door 31, and a roller 311 that can travel along the first limiting groove 111 installed on one side of the bottom of the furnace door 31. The support mechanism 2 includes a movable seat 22 that can move horizontally, and the top of the movable seat 22 is fixedly connected to the bottom of the furnace door 31 on the side away from the roller 311.

[0028] By installing a roller 311 on one side of the bottom of the furnace door 31, when the furnace door 31 moves, the furnace door 31 will drive the roller 311 to move along the first limiting groove 111. The roller 311 and the first limiting groove 111 cooperate to limit the furnace door 31, effectively preventing the furnace door 31 from deviating when it moves.

[0029] See Figure 1 , Figure 2 and Figure 3As shown, the support mechanism 2 also includes a first support frame 21, which is located below the furnace bottom plate 11. The two sides of one end of the first support frame 21 are fixed to the inner wall of the furnace body 1. The two sides of the top of the first support frame 21 are symmetrically provided with second limiting grooves 211. The inner walls on both sides of the first support frame 21 are horizontally fixed with slide rails 212. The bottom of the movable seat 22 is equipped with a roller 222 that can travel along the second limiting groove 211, and the two sides of the movable seat 22 are symmetrically provided with slide grooves 223 that can slide and cooperate with the slide rail 212.

[0030] To ensure the stability of the movable seat 22, two sliding grooves 223 are provided at the bottom of the movable seat 22, and rollers 222 are installed on both sides of the bottom of the movable seat 22. When the movable seat 22 moves, it drives the rollers 222 to travel along the second limiting groove 211. At the same time, the sliding grooves 223 at the bottom of the movable seat 22 slide along the slide rail 212. By utilizing the cooperation of the rollers 222 and the second limiting groove 211, as well as the cooperation of the sliding grooves 223 and the slide rail 212, the movable seat 22 is limited, effectively ensuring its stability.

[0031] See Figure 1 , Figure 2 and Figure 3 As shown, a second threaded hole 221 is provided at the bottom of the movable base 22; At the center of the top of the first support frame 21, a lead rod 23 is horizontally arranged, which can be inserted into the second threaded hole 221. The lead rod 23 is threadedly engaged with the second threaded hole 221. A servo motor 24 for driving the lead screw 23 to rotate is fixed on the first support frame 21, and the output end of the servo motor 24 is fixedly connected to the end of the lead screw 23.

[0032] When the servo motor 24 is started, it drives the lead screw 23 to rotate. At this time, the lead screw 23 drives the moving seat 22 to move horizontally through the second threaded hole 221 that is threaded with it, thereby realizing the horizontal movement of the moving seat 22.

[0033] See Figure 1 and Figure 8 As shown, a controller 7 is fixed on the outer wall of the furnace body 1; Heating wires 5 are symmetrically arranged on both sides inside the furnace body 1, and the two ends of the heating wires 5 are electrically connected to the controller 7 respectively; Several fixing rods 6 that can penetrate the ceramic fiber aerogel pad 8 and the insulation layer 4 are symmetrically fixed on the inner walls on both sides of the furnace body 1. One end of the fixing rod 6 is fixed with a second support frame 61 for mounting the heating wire 5.

[0034] By fixing the fixing rod 6 to the inner walls on both sides of the furnace body 1, and then using the second support frame 61 at the end of the fixing rod 6 to fix the heating wire 5, the two ends of the heating wire 5 are electrically connected to the controller 7, so that the controller 7 controls the heating wire 5 to be energized or de-energized. When the heating wire 5 is energized, it generates heat energy, and at this time, the internal temperature of the furnace body 1 rises.

[0035] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
