Abstract
Description
Technical Field
[0001] This application relates to the technical field of ceramic production equipment, and in particular to kilns for ceramic firing. Background Technology
[0002] In the ceramics manufacturing industry, the firing process plays a decisive role in the quality of ceramic products. As a key piece of equipment in ceramic firing, the performance of the kiln directly affects the quality of the ceramic products. Traditional ceramic firing kilns have revealed many problems in long-term practical application, among which the uneven heating of different surfaces during the firing process is particularly prominent.
[0003] In related technologies, most kilns employ relatively simple heating methods, such as common resistance wire heating or gas heating, resulting in significant differences in heat distribution within the kiln. Ceramic surfaces closer to the heat source tend to absorb heat quickly and heat up rapidly, while surfaces farther from the heat source heat up slowly, leading to inconsistent heating levels in different parts of the same ceramic product during firing. This uneven heating can consequently affect the production quality of the ceramic products. Utility Model Content
[0004] In order to improve the uniformity of heating of ceramic products, this application provides a kiln for ceramic firing.

[0007] By adopting the above technical solution, ceramics can be placed on a baking rack, which is then fixed to a support plate by a fixing component. The kiln body is then started to heat the ceramics on the baking rack. At the same time, the support plate is rotated by controlling the drive mechanism, thereby making the ceramics on the baking rack rotate with the baking rack, thus improving the uniformity of heating of ceramic products and improving the production quality of ceramics.
[0008] Optionally, the driving mechanism includes a drive motor, which is fixedly connected in the pit. The output shaft of the drive motor is coaxially arranged with the bearing plate, and a connecting component for connecting the two is provided between the output shaft of the drive motor and the bearing plate.

The plurality of abutment balls are equidistantly arranged along the circumference of the support sleeve, and the abutment balls abut against the bottom of the annular groove.
[0013] By adopting the above technical solution, the bearing plate can be supported by multiple abutment balls, while reducing the friction between the abutment balls and the bearing plate.
[0014] Optionally, the fixing component includes a plurality of limiting blocks arranged around the baking rack, and a locking element for fixing the limiting blocks to the support plate is provided between the limiting blocks and the support plate.

[0016] Optionally, the locking element is configured as a locking bolt, which is threadedly connected to both the bearing plate and the limiting block.
[0017] By adopting the above technical solution, the locking bolt can be rotated to disengage from the bearing plate, thereby canceling the fixation of the limiting block on the bearing plate.
[0018] Optionally, the support plate has multiple threaded holes arranged around the baking rack, and the shank of the locking bolt is threaded into the threaded holes.
[0019] By adopting the above technical solution, the number of limiting blocks required for fixing can be flexibly changed according to the number of ceramics on the barbecue grill by setting multiple threaded holes.
[0020] Optionally, a protective frame is fitted onto the limiting block, and the limiting block abuts against the baking rack through the protective frame.
[0021] By adopting the above technical solution, the limiting block and the baking rack can be protected by a protective frame.
[0022] In summary, this application includes at least one of the following beneficial technical effects:
[0023] 1. The drive mechanism can be controlled to rotate the bearing plate, thereby causing the ceramics on the baking rack to rotate with the baking rack, which improves the uniformity of heating of ceramic products and improves the production quality of ceramics.

[0031] The following is in conjunction with the appendix Figure 1 -Appendix Figure 4 This application will be described in further detail below.
[0032] The embodiment of this application is: a kiln for ceramic firing, referring to... Figure 1 , Figure 2 and Figure 3 The system includes a kiln body 1 installed on the factory ground, which is a ceramic kiln used for baking ceramics in the prior art. A foundation pit 2 is formed below the kiln body 1, and a support plate 3 is located at the upper end of the foundation pit 2, completely covering the upper part of the foundation pit 2. A support sleeve 4 is fixedly connected inside the foundation pit 2, and the support sleeve 4 is installed along the inner wall of the foundation pit 2. The support sleeve 4 is coaxially arranged with the support plate 3, and the support plate 3 is rotatably connected to the upper end of the support sleeve 4.
[0033] Reference Figure 2 , Figure 3 and Figure 4 The support sleeve 4 is equipped with a drive mechanism 5 for rotating the bearing plate 3. The drive mechanism 5 includes a drive motor 51, which is fixedly connected in the pit 2. The output shaft of the drive motor 51 is coaxial with the bearing plate 3. A connecting component 52 is provided between the output shaft of the drive motor 51 and the bearing plate 3 to connect the two. The connecting component 52 includes a spline 521 fixedly connected to the output shaft of the drive motor 51. A bushing 522 adapted to the spline 521 is fixedly connected below the axis of the bearing plate 3. The spline 521 is inserted into the bushing 522.
[0034] Furthermore, the drive motor 51 can be controlled to rotate, causing the drive motor 51 to drive the bearing plate 3 to rotate via the spline 521 and the peripheral sleeve. Simultaneously, to reduce the friction between the abutting balls 41 and the bearing plate 3, an annular groove 31 is formed at the lower end of the bearing plate 3. Multiple abutting balls 41 are rotatably connected to the upper end of the support sleeve 4. These balls 41 are equidistantly arranged along the circumference of the support sleeve 4, and abut against the bottom of the annular groove 31. The support sleeve 4 is rotatably connected to the bearing plate 3 via the annular groove 31 and the multiple abutting balls 41.
[0035] Reference Figure 1 , Figure 2 and Figure 3 The upper end of the support plate 3 is provided with a baking rack 6 for placing ceramics, and the support plate 3 is provided with a fixing component 7 for fixing the baking rack 6 to the support plate 3.
[0036] The fixing component 7 includes a plurality of limiting blocks 71 arranged around the baking rack 6. In this embodiment, there are eight limiting blocks 71. A locking member 72 is provided between the limiting blocks 71 and the support plate 3 for fixing the limiting blocks 71 to the support plate 3.
[0037] The support plate 3 has multiple threaded holes 32 arranged around the baking rack 6. In this embodiment, the locking element 72 is a locking bolt, and two locking bolts are provided on each limiting block 71. The locking bolts pass through and are threaded to the limiting block 71, and the shank of the locking bolt is threaded into the threaded hole 32.
[0038] By rotating the locking bolt, the locking bolt is disengaged from the bearing plate 3, thereby releasing the fixation of the limiting block 71 on the bearing plate 3. At the same time, in order to reduce the wear between the limiting block 71 and the baking rack 6, a protective frame 8 is fitted on the limiting block 71, and the limiting block 71 abuts against the baking rack 6 through the protective frame 8.
[0039] The implementation principle of this application embodiment is as follows: ceramics can be placed on the baking rack 6, and then a suitable number of limiting blocks 71 can be placed to limit the position of the baking rack 6, thereby fixing the baking rack 6 on the support plate 3. Then, the kiln body 1 is started to heat the ceramics on the baking rack 6. At the same time, the drive motor 51 is started to drive the support plate 3 to rotate, thereby making the ceramics on the baking rack 6 rotate with the baking rack 6, thereby improving the uniformity of heating of ceramic products.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
