Description

Technical Field

[0001] This utility model relates to the field of ceramic material sintering furnaces, and in particular to a sintering furnace for composite zirconium aluminum cerium silicon nano-electronic ceramic materials. Background Technology

[0002] Zirconium-aluminum-cerium-silicon nanoceramics combine the properties of nanomaterials with the synergistic effect of composite components. Cerium (Ce) acts as a stabilizer, forming a solid solution with zirconium oxide to suppress the transformation from tetragonal to monoclinic phase at high temperatures, reducing crack propagation caused by phase transformation stress and achieving a phase transformation toughening effect. The introduction of aluminum and silicon components further modulates the coefficient of thermal expansion, enhancing high-temperature stability. Alumina provides high hardness and wear resistance, while silicon promotes glass phase formation, improving the material's thermal shock resistance. The multiphase composite structure balances the material's toughness, strength, and corrosion resistance through a grain boundary strengthening mechanism. The nanoscale powder, due to its huge specific surface area and surface energy, significantly improves sintering activity, enabling high-density molding at temperatures lower than traditional ceramic sintering temperatures, effectively suppressing abnormal grain growth while reducing energy consumption.

[0003] When sintering zirconium, aluminum, cerium, and silicon nano-ceramic materials in a sintering furnace, since there are usually four heating points inside the furnace, the materials closest to the heating points are the first to be heated and reacted, regardless of whether it is preheating, medium temperature, or high temperature. This leads to differences in the maturity of the sintered materials, and thus differences in the maturity time of the sintered crystals. If the sintering volume is large, it is inevitable that the quality of the sintered ceramic materials will be uneven. After sintering, zirconium, aluminum, cerium, and silicon nano-ceramic materials need to be cooled slowly and then removed. Usually, small zirconium, aluminum, cerium, and silicon nano-ceramic materials are handled manually, which can cause bumps and scratches during handling, resulting in surface defects. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a sintering furnace for composite zirconium, aluminum, cerium, and silicon nano-electronic ceramic materials.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a sintering furnace for composite zirconium aluminum cerium silicon nano-electronic ceramic materials, comprising a furnace body, wherein a square connecting rod is slidably and rotatably connected to the bottom wall of the furnace body via a bearing, the lower end of the square connecting rod passes through the furnace body and is rotatably connected to a connecting ring, the connecting ring is fixedly connected to a connecting rod, the other end of the connecting rod is connected to an electric telescopic rod, the bottom wall of the furnace body is symmetrically provided with limit slide rails, each limit slide rail is slidably provided with a slider, the top of the slider is fixedly connected to a slide plate, the top of the slide plate is rotatably connected to a rotating plate, the bottom end of the rotating plate is fixedly connected to a mating sleeve, the bottom of the mating sleeve is provided with a mating groove that mates with the square connecting rod, the bottom wall of the furnace body is fixedly provided with a fixing frame to a second motor, the drive end of the second motor is fixedly connected to a drive sleeve, the drive sleeve is mated and connected to the lower part of the square connecting rod through a square mating hole provided at the top;

[0006] Furthermore, after the blank made of composite zirconium aluminum cerium silicon nano-electronic ceramic material is pressed into shape, it is placed in a sintering tray. The sintering tray is placed on a rotating plate or fixed on it. At this time, the first motor drives the slider to return from the guide rail to the limit slide rail through the threaded rod. Then, the mating sleeve gradually enters the furnace body. Afterward, the electric telescopic rod drives the connecting ring to extend the square connecting rod from the bottom of the furnace body through the connecting rod. At this time, the mating groove of the mating sleeve and the square connecting rod are engaged. The first motor stops working, so that the rotating plate is in the center of the furnace body. Since the bottom of the square connecting rod is engaged with the drive sleeve, the second motor drives the square connecting rod to drive the rotating plate to rotate on the slide plate through the drive sleeve. This allows the sintering tray to be heated evenly when burning in the furnace body. At this time, the composite zirconium aluminum cerium silicon nano-electronic ceramic material blank can be heated evenly in the preheating, medium temperature or high temperature stage. This ensures that the sintering and crystallization progress of the composite zirconium aluminum cerium silicon nano-electronic ceramic material blank is the same, the hardening and fusion progress is the same, and the maturation time between sintered crystal grains is the same, resulting in stable and balanced quality.

[0007] Preferably, a sintering drawer is provided on the upper part of the rotating plate, and a blank formed by pressing zirconium aluminum cerium silicon nano-electronic ceramic material is provided in the sintering drawer.

[0008] Furthermore, the raw materials on the sintering tray are all pressed from composite zirconium, aluminum, cerium, and silicon nano-electronic ceramic materials. There are many types of composite zirconium, aluminum, cerium, and silicon nano-electronic ceramic material blanks, which will not be listed in detail. However, all blanks processed from composite zirconium, aluminum, cerium, and silicon nano-electronic ceramic materials can be fired in this sintering furnace. The sintering tray is made of ceramic or other refractory materials, which ensures that the sintering temperature is uniformly heated and stable, without rapid temperature changes, resulting in good sintering effect.

[0009] Preferably, the docking sleeve rotatably penetrates the sliding plate;

[0010] Furthermore, the mating sleeve is designed to be rotated by a square connecting rod.

[0011] Preferably, the electric telescopic rod is fixed to the outside of the furnace body;

[0012] Furthermore, the electric telescopic rod controls the engagement and disengagement of the square connecting rod and the docking sleeve.

[0013] Preferably, the furnace body has an insulation layer inside the side wall, burners are installed on both inner walls of the furnace body, support legs are installed at the bottom of the furnace body, and the furnace body is connected to a vacuum system and a waste gas treatment system.

[0014] Furthermore, the furnace body insulation layer enables temperature control during sintering, the burner can raise and control the temperature inside the furnace, the support legs are used to support the furnace body, the vacuum system is used for process control of firing composite zirconium aluminum cerium silicon nano-electronic ceramic material blanks in the furnace body to facilitate crystal formation, and the exhaust gas treatment system is used for gas purification during the sintering process of composite zirconium aluminum cerium silicon nano-electronic ceramic materials, which is environmentally friendly.

[0015] Preferably, a door panel is hinged to the front side of the furnace body, and guide rails for guiding the slider docking are symmetrically arranged on the rear side of the door panel;

[0016] Furthermore, the door panel is used to support the discharge material after sintering, and can also be used to support the placement of the feed material. The door panel can also be used to close the furnace body to form a sealed sintering space.

[0017] Preferably, one of the sliders is threadedly connected to a threaded rod, one end of which is rotatably connected to the furnace body via a bearing seat, and the other end of which passes through the furnace body and is fixedly connected to a first motor, which is installed on the outside of the furnace body;

[0018] Furthermore, the first motor drives the slider to slide within the limit rail via a threaded rod. The slider can then use a sliding plate to move the rotating plate and the sintering tray into and out of the furnace body, thus realizing automatic loading and unloading of composite zirconium aluminum cerium silicon nano-electronic ceramic materials. This automated loading and unloading saves labor and avoids the problem of manual handling and bumping during the sintering of small zirconium aluminum cerium silicon nano-ceramic materials. It ensures the qualified appearance of the sintered product and prevents appearance defects caused by the brittleness of hard contact.

[0019] Preferably, a limiting block is installed on one side of one of the sliders, and a limiting groove is formed on the upper inner side of the corresponding limiting slide rail, and the limiting block is slidably limited in the limiting groove.

[0020] Furthermore, when the slider slides, the limiting block and limiting groove restrict its movement, preventing the slider from disengaging from the threaded rod and from detaching from the limiting slide rail, while also allowing the slider to be guided by the guide rail.

[0021] This utility model has the following beneficial effects:

[0022] In this invention, the first motor drives the slider to return completely from the guide rail to the limiting slide rail via a threaded rod. At this time, the mating sleeve gradually enters the furnace body. Then, the electric telescopic rod drives the connecting ring to extend the square connecting rod from the bottom of the furnace body via a connecting rod. At this time, the mating groove of the mating sleeve and the square connecting rod engage. The first motor stops working, so that the rotating plate is in the center of the furnace body. Since the bottom of the square connecting rod engages with the driving sleeve, the second motor drives the square connecting rod to rotate the rotating plate on the slide plate via the driving sleeve. This ensures that the sintering tray can be heated evenly when burning in the furnace body. At this time, the composite zirconium aluminum cerium silicon nano-electronic ceramic material blanks can be heated evenly, whether in the preheating, medium temperature, or high temperature stage. This ensures that the sintering and crystallization progress of the composite zirconium aluminum cerium silicon nano-electronic ceramic material blanks is the same, and the hardening and fusion progress is the same. This achieves the same maturation time between sintered crystal grains and stable and balanced quality.

[0023] In this invention, the first motor drives the slider to slide within the limiting slide rail via a threaded rod. The slider can move the rotating plate through the sliding plate to move the sintering tray into and out of the furnace body. When the slider slides, the limiting block and limiting groove restrict its movement, preventing the slider from disengaging from the threaded rod and the limiting slide rail. The slider can also be guided by the guide rail to output the sintering raw materials in the sintering tray. This realizes automatic loading and unloading of composite zirconium aluminum cerium silicon nano-electronic ceramic materials. The automatic loading and unloading saves labor and avoids the problem of manual handling and bumping when sintering small zirconium aluminum cerium silicon nano-ceramic materials. It ensures the qualified appearance of the sintered product and prevents appearance defects caused by the brittleness of hard contact. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1-5One embodiment of this utility model provides a sintering furnace for composite zirconium, aluminum, cerium, and silicon nano-electronic ceramic materials, comprising a furnace body 1. A square connecting rod 13 is rotatably connected to the bottom wall of the furnace body 1 via a bearing. The lower end of the square connecting rod 13 passes through the furnace body 1 and is rotatably connected to a connecting ring 18. A connecting rod 10 is fixedly connected to the connecting ring 18. An electric telescopic rod 9 is connected to the other end of the connecting rod 10. Limiting slide rails 7 are symmetrically arranged on the bottom wall of the furnace body 1. Sliding sliders 12 are slidably arranged within the limiting slide rails 7. A sliding plate 8 is fixedly connected to the top of each sliding slider 12. A rotating plate 6 is rotatably connected to the top of the sliding plate 8, and a docking sleeve 21 is fixedly connected to the bottom of the rotating plate 6. The bottom of the docking sleeve 21 has a docking groove that mates with the square connecting rod 13. A second motor 20 is fixed to the bottom wall of the furnace body 1 via a fixing frame 17. A driving sleeve 19 is fixedly connected to the drive end of the second motor 20. The driving sleeve 19 is connected to the lower part of the square connecting rod 13 via a square mating hole at the top. After the blank made of composite zirconium aluminum cerium silicon nano-electronic ceramic material is pressed into shape, it is placed in the sintering tray 2. The sintering tray 2 Placed on or fixed to the rotating plate 6, the first motor 14 drives the slider 12 from the guide rail 5 back into the limiting slide rail 7 via the threaded rod 11. At this time, the mating sleeve 21 gradually enters the furnace body 1. Then, the electric telescopic rod 9, through the connecting rod 10, causes the connecting ring 18 to drive the square connecting rod 13 to extend from the bottom of the furnace body 1. At this time, the mating groove of the mating sleeve 21 engages with the square connecting rod 13. The first motor 14 stops working, placing the rotating plate 6 in the center of the furnace body 1. Because the bottom of the square connecting rod 13 engages with... Drive sleeve 19, so at this time, the second motor 20 drives the square connecting rod 13 to rotate the rotating plate 6 on the slide plate 8 through drive sleeve 19, so that the sintering tray 2 can be heated evenly when burning in the furnace body 1. At this time, whether it is preheating or firing in the medium or high temperature stage, the composite zirconium aluminum cerium silicon nano electronic ceramic material blank can be heated evenly, so that the sintering and crystallization progress of the composite zirconium aluminum cerium silicon nano electronic ceramic material blank is the same, the hardening and fusion progress is the same, and the maturation time between sintered crystal grains is the same, resulting in stable and balanced quality.

[0033] The upper part of the rotating plate 6 is equipped with a sintering tray 2, which contains blanks formed by pressing zirconium aluminum cerium silicon nano-electronic ceramic materials. The raw materials on the sintering tray 2 are all made of composite zirconium aluminum cerium silicon nano-electronic ceramic materials. There are many types of composite zirconium aluminum cerium silicon nano-electronic ceramic material blanks, which are not listed in detail. However, all blanks processed from composite zirconium aluminum cerium silicon nano-electronic ceramic materials can be fired in this sintering furnace. The sintering tray 2 is made of ceramic or other refractory materials, which makes the sintering temperature uniform and stable, and prevents rapid temperature changes, resulting in good sintering effect.

[0034] The docking sleeve 21 rotates through the slide plate 8, and the docking sleeve 21 is driven by the square connecting rod 13 to facilitate rotation.

[0035] The electric telescopic rod 9 is fixed to the outside of the furnace body 1. The electric telescopic rod 9 controls the engagement and disengagement of the square connecting rod 13 and the docking sleeve 21.

[0036] The furnace body 1 has an insulation layer inside its side wall, and burners 3 are installed on both inner walls of the furnace body 1. Support legs are installed at the bottom of the furnace body 1. The furnace body 1 is connected to a vacuum system and a waste gas treatment system. The insulation layer of the furnace body 1 enables temperature control during sintering. The burners 3 can raise and control the temperature inside the furnace body 1. The support legs are used to support the furnace body 1. The vacuum system is used for process control of firing composite zirconium aluminum cerium silicon nano-electronic ceramic material blanks in the furnace body 1, which facilitates crystal formation. The waste gas treatment system is used for gas purification during the sintering process of composite zirconium aluminum cerium silicon nano-electronic ceramic materials, which is environmentally friendly.

[0037] A door panel 4 is hinged to the front side of the furnace body 1. A guide rail 5 for docking and guiding the slider 12 is symmetrically arranged on the rear side of the door panel 4. The door panel 4 is used to carry the material discharged after sintering and can also be used to carry the material to be fed. The door panel 4 can also be used to close the furnace body 1 to form a sealed sintering space.

[0038] One of the sliders 12 is threadedly connected to a threaded rod 11. One end of the threaded rod 11 is rotatably connected to the furnace body 1 through a bearing seat. The other end of the threaded rod 11 passes through the furnace body 1 and is fixedly connected to a first motor 14. The first motor 14 is installed on the outside of the furnace body 1. The first motor 14 drives the slider 12 to slide within the limiting slide rail 7 through the threaded rod 11. The slider 12 can drive the rotating plate 6 to move the sintering tray 2 from the furnace body 1 through the sliding plate 8. This realizes the automatic loading and unloading of composite zirconium aluminum cerium silicon nano-electronic ceramic materials for sintering. The automatic loading and unloading saves labor and avoids the problem of small zirconium aluminum cerium silicon nano-ceramic materials being handled manually by picking them up and dropping them, ensuring the qualified appearance of the sintered product and preventing appearance defects caused by the brittleness of hard contact.

[0039] One of the sliders 12 is equipped with a limiting block 16 on one side, and a limiting groove 15 is opened on the upper inner side of the corresponding limiting slide rail 7. The limiting block 16 slides and is limited in the limiting groove 15. When the slider 12 slides, the limiting block 16 and the limiting groove 15 restrict its movement, preventing the slider 12 from disengaging from the threaded rod 11 and from disengaging from the limiting slide rail 7, while the slider 12 can also be guided by the guide rail 5.

[0040] Working principle: During feeding, the blank made of composite zirconium aluminum cerium silicon nano-electronic ceramic material is pressed into shape and placed into the sintering tray 2. The sintering tray 2 is placed on the rotating plate 6 or fixed on it. The first motor 14 drives the slider 12 to slide within the limiting slide rail 7 through the threaded rod 11. The slider 12 can drive the rotating plate 6 to move the sintering tray 2 in and out of the furnace body 1 through the sliding plate 8, realizing automatic loading and unloading of composite zirconium aluminum cerium silicon nano-electronic ceramic material sintering. The automatic loading and unloading saves labor and avoids the problem of small zirconium aluminum cerium silicon nano-ceramic materials being handled manually and bumped during sintering. This ensures the qualified appearance of the sintered product and prevents appearance defects caused by the brittleness of hard contact. During firing, the burner 3 preheats the furnace body 1 or fires at medium or high temperature. At this time, the first motor 14 drives the slider 12 to return from the guide rail 5 to the limiting slide rail 7 through the threaded rod 11. At this point, the docking sleeve 21 gradually enters the furnace body 1. Then, the electric telescopic rod 9, through the connecting rod 10, causes the connecting ring 18 to drive the square connecting rod 13 to extend from the bottom of the furnace body 1. At this point, the mating groove of the docking sleeve 21 and the square connecting rod 13 are engaged. At this time, the first motor 14 stops working, so that the rotating plate 6 is in the center of the furnace body 1. Since the bottom of the square connecting rod 13 is engaged with the drive sleeve 19, the second motor 20, through the drive sleeve 19, causes the square connecting rod 13 to drive the rotating plate 6 to rotate on the slide plate 8, so that the sintering tray 2 can be heated evenly when burning in the furnace body 1. At this time, whether it is preheating or firing in the medium or high temperature stage, the composite zirconium aluminum cerium silicon nano-electronic ceramic material blank can be heated evenly, so that the sintering and crystallization progress of the composite zirconium aluminum cerium silicon nano-electronic ceramic material blank is the same, the hardening and fusion progress is the same, and the maturation time between the sintered crystal grains is the same, resulting in stable and balanced quality.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
