[0026] Please see Figures 1-4 A standby kiln furnace for zirconium oxide powder system is proposed, including a rectangular furnace chamber 1, an operating platform 2, a sealing door 7, and a rectangular sealing assembly.

[0027] An operating table 2 is installed at the operating point on the rectangular furnace 1. A sealing door 7 is provided at the sealing point on the rectangular furnace 1. The rectangular furnace 1 and the sealing door 7 are installed at the merging point on the rectangular sealing assembly. A cylindrical assembly is installed on the rectangular furnace 1. A tunnel assembly is set on the rectangular furnace 1.

[0028] Trace amounts of alumina-reinforced nano-zirconia powder are introduced into the rectangular furnace chamber 1, and the operation is carried out through the operating table 2 on the rectangular furnace chamber 1. The sealing door 7 is then sealed and installed on the rectangular furnace chamber 1. The heating elements of the rectangular furnace chamber 1, such as resistance wires and silicon carbide rods, are distributed on both sides or the top of the furnace chamber, which can be used to prepare trace amounts of alumina-reinforced nano-zirconia powder.

[0029] The rectangular furnace chamber 1 is equipped with a servo motor 4 at its rear end, a cylindrical body 3 at the sliding part of the rectangular furnace chamber 1, a bearing ring 5 at the front end of the cylindrical body 3, a support rod 8 fixed at the support part of the bearing ring 5, a feeding port 6 at the feeding part of the bearing ring 5, and a furnace box 9 at the sliding part at the bottom of the rectangular furnace chamber 1.

[0030] In this embodiment, the support rod 8 is fixedly connected inside the rectangular furnace chamber 1, so that the bearing ring 5 on the cylindrical body 3 is fixed on the support rod 8. The cylindrical body 3 slides through the bearing ring 5. The furnace chamber 9 is installed inside the rectangular furnace chamber 1, so that trace amounts of alumina-reinforced nano-zirconia powder can be separately added into the rectangular furnace chamber 1, the furnace chamber 9 and the cylindrical body 3 for classified preparation. The cylindrical body 3 is driven by the servo motor 4 to rotate, so as to avoid uneven heating of the trace amounts of alumina-reinforced nano-zirconia powder.

[0031] Preferably, the cylindrical body 3 is slidably mounted on the bearing ring 5 and the support rod 8. The cylindrical body 3 is slidably mounted on the bearing ring 5 and rotates under the drive of the servo motor 4. The support rod 8 can support the bearing ring 5 and the bottom of the cylindrical body 3. The cylindrical body 3 can rotate inside the rectangular furnace chamber 1. The heating elements of the rectangular furnace chamber 1, such as resistance wires and silicon carbide rods, are distributed on both sides or the top of the furnace chamber, which can heat the trace amount of alumina-reinforced nano-zirconia powder inside the cylindrical body 3.

[0032] Preferably, trace amounts of alumina-reinforced nano-zirconia powder can be placed inside the furnace chamber 9 and the rectangular furnace chamber 1. The trace amounts of alumina-reinforced nano-zirconia powder can be directly added to the rectangular furnace chamber 1 or placed inside the furnace chamber 9 for heating. The trace amounts of alumina-reinforced nano-zirconia powder are prepared by heating in two different ways.

[0033] Please refer to Figure 2 and Figure 3 In this embodiment, the cylindrical assembly includes a rotary bearing 10 slidably mounted on a cylindrical body 3, a mounting plate 11 is fastened to the threaded portion of the cylindrical body 3, a drive shaft 12 is provided on the drive portion of the mounting plate 11, and a ball bearing ring 13 is provided on the sliding portion of the bearing ring 5.

[0034] The steel ball bearing ring 13 is installed inside the bearing ring 5. When the cylindrical body 3 is driven to rotate by the servo motor 4, the cylindrical body 3 slides and flips inside the bearing ring 5 through the steel ball bearing ring 13. The mounting plate 11 is threadedly fastened to the rear end of the cylindrical body 3. The drive shaft 12 on the servo motor 4 can be threadedly fastened to the rear end of the cylindrical body 3 through the mounting plate 11.

[0035] Preferably, the drive shaft 12 drives the cylindrical body 3 to rotate on the steel ball bearing 13 and the rotary bearing 10. When the cylindrical body 3 is slidably mounted on the steel ball bearing 13 and the rotary bearing 10, the cylindrical body 3 can be driven by the servo motor 4. The servo motor 4 can push the drive shaft 12 through the mounting plate 11, which can make the cylindrical body 3 rotate and flip. When a small amount of alumina-reinforced nano-zirconia powder is put into the cylindrical body 3 and the feeding port 6, the rectangular furnace 1 and the cylindrical body 3 are heated and prepared at the same time. This can reduce the occupied area and reduce the cost, as well as the amount of R&D investment in the preparation of alumina-reinforced nano-zirconia powder. The cylindrical body 3 is in motion to avoid a large accumulation of material thickness and to prevent uneven heating. The rectangular furnace 1 and the cylindrical body 3 can be combined for preparation and R&D.

[0036] Please refer to Figure 3 and Figure 4 In this embodiment, the tunnel assembly includes a groove 14 formed on the furnace box 9, and a tunnel block 15 is installed at a sliding part on the groove 14.

[0037] The tunnel block 15 is fixedly connected to the inside of the rectangular furnace chamber 1. The groove 14 on the furnace chamber 9 is slidably installed on the tunnel block 15. The furnace chamber 9 is slidably installed inside the rectangular furnace chamber 1 through the tunnel block 15.

[0038] Preferably, the groove 14 and the furnace box 9 are slidably installed inside the rectangular furnace 1 via the tunnel block 15. Users can add different amounts of trace alumina-reinforced nano-zirconia powder. The furnace box 9 is slidably installed inside the rectangular furnace 1, which facilitates laboratory preparation and research based on the amount of trace alumina-reinforced nano-zirconia powder added. The rectangular furnace 1, furnace box 9 and cylindrical cylinder 3 are heated simultaneously for preparation, reducing the amount of trace alumina-reinforced nano-zirconia powder required for preparation and research. This facilitates the classification and preparation of trace alumina-reinforced nano-zirconia powder, and allows for the addition of larger amounts of powder for preparation and research through the rectangular furnace 1, furnace box 9 and cylindrical cylinder 3.

[0039] As can be seen from the above, during use, the cylindrical body 3 slides through the bearing ring 5. When the furnace chamber 9 is installed inside the rectangular furnace chamber 1, trace amounts of alumina-reinforced nano-zirconia powder can be separately added into the rectangular furnace chamber 1, the furnace chamber 9, and the cylindrical body 3 for classified preparation. In the laboratory, the preparation and research are carried out according to the amount of trace amounts of alumina-reinforced nano-zirconia powder added. The preparation is carried out by heating the rectangular furnace chamber 1, the furnace chamber 9, and the cylindrical body 3 simultaneously, which reduces the amount of trace amounts of alumina-reinforced nano-zirconia powder to be added for preparation and research.

[0040] The cylindrical body 3 slides and flips inside the bearing ring 5 via the steel ball collar 13. The mounting plate 11 is threadedly fastened to the rear end of the cylindrical body 3. The drive shaft 12 on the servo motor 4 is threadedly fastened to the rear end of the cylindrical body 3 via the mounting plate 11. The cylindrical body 3 can be driven by the servo motor 4, which can push the drive shaft 12 through the mounting plate 11, causing the cylindrical body 3 to rotate and flip. When a small amount of alumina-reinforced nano-zirconia powder is put into the cylindrical body 3 and the feeding port 6, the rectangular furnace 1 and the cylindrical body 3 are heated and prepared simultaneously, which can reduce the occupied area and reduce the cost.
