Description

Technical Field

[0001] This utility model relates to the field of mullite kiln furniture technology, specifically to a combined mullite kiln furniture for pusher kilns. Background Technology

[0002] Mullite kiln furniture is a refractory material with mullite as its main component. It possesses characteristics such as high melting point, good thermal stability, and strong thermal shock resistance, maintaining stable structural properties at high temperatures. It is widely used in industries such as ceramics, glass, chemicals, metallurgy, and energy. In ceramic production, it is used to support and fix ceramic products, having a decisive impact on the final product quality. In the glass manufacturing industry, as a refractory material in glass furnaces, it can withstand extremely high temperatures and resist the erosion of molten glass. Furthermore, mullite kiln furniture can be combined with materials such as cordierite and corundum to further enhance its performance and meet the needs of different industrial scenarios.

[0003] Chinese patent CN210602821U discloses a kiln furniture for firing refractory balls in a tunnel kiln, comprising two first tubes and one second tube. A first tube is installed at each end of the second tube, and the two first tubes are movably connected to the second tube. Second interlocking parts are provided at both ends of the second tube, and first interlocking parts that cooperate with the second interlocking parts are provided at one end of each of the two first tubes. The first and second tubes are movably connected through the first and second interlocking parts. The modular kiln furniture body can support and bear the refractory balls without affecting the firing effect. The third tube enhances the support effect of the kiln furniture. The wavy, raised interlocking parts enhance the circumferential support of the kiln furniture and facilitate stacking by operators. Handles facilitate handling by operators. The use of silicon carbide material improves the performance and service life of the kiln furniture.

[0004] The kiln furniture described in the aforementioned patent document consists of a kiln furniture body and multiple jars. While these can be joined together to increase storage space, existing kiln furniture results in the billets being completely stacked inside, causing them to easily stick together during firing and affecting the quality of the finished product. Therefore, a combined mullite kiln furniture for pusher kilns is proposed. Utility Model Content

[0005] To address the aforementioned issues, a modular mullite kiln furniture for pusher kilns is provided. By modularizing the kiln furniture into a kiln furniture base, kiln furniture sleeve, and kiln furniture top cover that can be assembled with each other, the kiln furniture sleeve and kiln furniture top cover can be repeatedly stacked. This allows the kiln furniture to meet the requirement of firing multiple sets of blanks simultaneously, while ensuring that the blanks remain independent of each other, thus solving the problem of blanks sticking together during the firing process.

[0006] To address the existing technical problems, this application provides a combined mullite kiln furniture for pusher kilns, including a kiln furniture base, a kiln furniture sleeve disposed on the top of the kiln furniture base, and a kiln furniture top cover disposed on the top of the kiln furniture sleeve.

[0007] The kiln tool sleeve is installed at the top of the ring enclosure, and multiple sets of kiln tool sleeves can be connected and extended.

[0008] The kiln furniture top cover can be connected to the top of the kiln furniture sleeve or the top of the annular enclosure.

[0009] As one technical solution of this application, the top of the annular enclosure is provided with a first conical surface;

[0010] The bottom end of the kiln tool sleeve is provided with a first bottom conical groove that can be adapted to the first conical surface.

[0011] As one technical solution of this application, the top end of the kiln tool sleeve has a second conical surface;

[0012] The bottom of the kiln furniture top cover is provided with a second bottom conical groove that can be adapted to the second conical surface;

[0013] The top edge of the kiln furniture cover is also provided with a third conical surface that can be adapted to the first bottom conical groove.

[0014] As a technical solution of this application, the surface of the annular enclosure is coated with a first anti-adhesion coating that can prevent it from adhering to the surface of the first bottom conical groove.

[0015] The surface of the second conical surface is coated with a second anti-adhesion coating that prevents it from adhering to the surface of the second bottom conical groove.

[0016] As one technical solution of this application, the surface of the kiln furniture sleeve is provided with a number of annular reinforcing ribs around its central axis, and the annular reinforcing ribs are arranged at equal intervals along the longitudinal direction of the central axis of the kiln furniture sleeve.

[0017] The surface of the kiln furniture sleeve is also provided with several longitudinal reinforcing ribs, which are equidistantly arranged around the central axis of the kiln furniture sleeve.

[0018] As one technical solution of this application, a first mesh feeding platform for placing billets is provided at the center of the upper end face of the kiln furniture base.

[0019] As one technical solution of this application, a second mesh feeding platform for placing billets is provided at the center of the upper end face of the kiln cover.

[0020] The advantages of this utility model compared to the prior art are:

[0021] This application modularizes the kiln furniture into a kiln furniture base, kiln furniture sleeve, and kiln furniture top cover that can be assembled with each other. This allows the kiln furniture to be repeatedly stacked, enabling the kiln furniture to meet the requirement of firing multiple sets of blanks simultaneously while keeping the blanks independent and solving the problem of the blanks sticking together during the firing process.

[0030] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0031] See Figures 1-7As shown, a combined mullite kiln furniture for pusher kilns includes a kiln furniture base 1, a kiln furniture sleeve 2 disposed on the top of the kiln furniture base 1, and a kiln furniture top cover 3 disposed on the top of the kiln furniture sleeve 2. An annular enclosure 11 is fixed on the upper end face of the kiln furniture base 1, and the central axis of the annular enclosure 11 coincides with the central axis of the kiln furniture base 1.

[0032] The kiln tool sleeve 2 is installed at the top of the annular enclosure 11, and the kiln tool sleeve 2 can be extended by multiple sets of joints;

[0033] The kiln furniture top cover 3 can be connected to the top of the kiln furniture sleeve 2 or the top of the annular enclosure 11.

[0034] To accommodate the firing of billets with varying heights, the kiln furniture is modularly designed as a kiln furniture base 1, kiln furniture sleeve 2, and kiln furniture top cover 3 that can be assembled with each other. When firing billets with smaller heights, the billet is placed on the upper surface of the kiln furniture base 1 inside the annular enclosure 11. Then, the bottom end of the kiln furniture sleeve 2 is fitted onto the top end of the annular enclosure 11, and the bottom end of the kiln furniture top cover 3 is fitted onto the top end of the kiln furniture sleeve 2, thus sealing the top end of the kiln furniture sleeve 2. Another set of billets is then placed on top of the kiln furniture top cover 3, and the bottom end of another kiln furniture sleeve 2 is fitted onto the top end of the kiln furniture top cover 3. By repeatedly stacking the kiln furniture sleeve 2 and the kiln furniture top cover 3, the kiln furniture can accommodate the simultaneous firing of multiple sets of billets. When the blanks are tall, multiple sets of kiln furniture sleeves 2 can be stacked until the internal space of the kiln furniture is sufficient for placement. A kiln furniture top cover 3 is then installed on top of the uppermost kiln furniture sleeve 2, making the internal and external spaces of the kiln furniture sleeve 2 independent. This allows the kiln furniture to be assembled according to the height of the blanks, solving the problem that the internal space of the kiln furniture limits its ability to fire blanks of different heights.

[0035] See Figure 5 and Figure 7 As shown, the top of the annular enclosure 11 has a first conical surface 13;

[0036] The bottom end of the kiln tool sleeve 2 is provided with a first bottom conical groove 21 that can be adapted to the first conical surface 13.

[0037] To achieve rapid and accurate connection between the kiln furniture sleeve 2 and the annular enclosure 11, a first conical surface 13 is formed at the top of the annular enclosure 11, and a first bottom conical groove 21 is formed at the bottom of the kiln furniture sleeve 2. When the kiln furniture sleeve 2 is installed at the top of the annular enclosure 11, the first conical surface 13 at the top of the annular enclosure 11 inserts into the first bottom conical groove 21, allowing the first conical surface 13 and the first bottom conical groove 21 to cooperate and convert axial thrust into radial support force through the taper angle, forming a self-locking mechanism. This improves the speed of assembly between the kiln furniture sleeve 2 and the annular enclosure 11.

[0038] See Figure 5 and Figure 6 As shown, the top of the kiln tool sleeve 2 has a second conical surface 22;

[0039] The bottom of the kiln furniture top cover 3 is provided with a second bottom conical groove 34 that can be adapted to the second conical surface 22;

[0040] The top edge of the kiln cover 3 is also provided with a third conical surface 33 that can be adapted to the first bottom conical groove 21.

[0041] To achieve rapid assembly between the kiln furniture top cover 3 and the kiln furniture sleeve 2, a second bottom conical groove 34 is provided at the bottom of the kiln furniture top cover 3. This allows the kiln furniture sleeve 2 to be inserted into the second bottom conical groove 34 through the second conical surface 22 at its top. The second conical surface 22 and the second bottom conical groove 34 then engage to form a self-locking mechanism, thereby improving the speed of assembly between the kiln furniture sleeve 2 and the kiln furniture top cover 3.

[0042] See Figure 4 As shown, the surface of the first conical surface 13 is coated with a first anti-adhesion coating 111 that prevents it from adhering to the surface of the first bottom conical groove 21;

[0043] The surface of the second conical surface 22 is coated with a second anti-adhesion coating 221 that prevents it from adhering to the surface of the second bottom conical groove 34.

[0044] The first anti-adhesion coating 111 and the second anti-adhesion coating 221 are preferably graphene composite ceramic coatings. Utilizing the characteristic that graphene composite ceramic coatings can withstand high temperatures of 1200-1400℃ for extended periods, the problem of kiln furniture sticking together in high-temperature environments is effectively avoided.

[0045] See Figure 5 and Figure 7 As shown, the surface of the kiln furniture sleeve 2 is provided with several annular reinforcing ribs 25 around its central axis, and the annular reinforcing ribs 25 are arranged at equal intervals along the longitudinal direction of the central axis of the kiln furniture sleeve 2.

[0046] The surface of the kiln furniture sleeve 2 is also provided with several longitudinal reinforcing ribs 24, which are equidistantly arranged around the central axis of the kiln furniture sleeve 2.

[0047] To improve the deformation resistance of the kiln furniture sleeve 2 in high-temperature environments, several annular reinforcing ribs 25 are equidistantly arranged along its central axis on the outer wall of the kiln furniture sleeve 2, and several longitudinal reinforcing ribs 24 are equidistantly arranged around its central axis on the outer wall of the kiln furniture sleeve 2. This creates a regular mesh structure on the surface of the kiln furniture sleeve 2, allowing the longitudinal reinforcing ribs 24 and the annular reinforcing ribs 25 to work together to increase the deformation resistance of the kiln furniture sleeve 2. This not only effectively prevents deformation of the kiln furniture sleeve 2 in high-temperature environments but also reduces the risk of cracking due to thermal expansion.

[0048] See Figure 5 As shown, a first mesh feeding platform 12 for placing billets is provided at the center of the upper end face of the kiln furniture base 1.

[0049] By setting a first conical surface 13 on the upper end face of the kiln furniture base 1, the contact area between the bottom end of the billet and the kiln furniture base 1 is reduced when the billet is placed on the kiln furniture base 1, thereby reducing the risk of the bottom of the billet sticking to the kiln furniture base 1.

[0050] See Figure 5 As shown, a second mesh feeding platform 32 for placing billets is provided at the center of the upper end face of the kiln furniture top cover 3.

[0051] By setting a second mesh feeding platform 32 on the upper surface of the kiln furniture top cover 3, the contact area between the bottom of the billet and the kiln furniture top cover 3 is reduced when the billet is placed on the kiln furniture top cover 3, thereby reducing the risk of the bottom of the billet sticking to the kiln furniture top cover 3.

[0052] 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.
