Technical Field

[0001] The utility model relates to the technical field of ceramic production, in particular to a high-temperature refractory ceramic metallization sintering furnace. Background Art

[0002] A sintering furnace is a furnace that, at high temperatures, enables the mutual connection of solid particles of ceramic green bodies, the growth of crystal grains, the gradual reduction of voids and grain boundaries, and through the transfer of substances, the overall volume shrinks, the density increases, and finally becomes a dense polycrystalline sintered body with a certain microstructure.

[0003] In the Chinese utility model patent with the publication number CN214950592U, a sintering furnace for ceramic parts is disclosed, including: a furnace body, a base is fixedly installed at the bottom of the furnace body, a box door is hinged to the front end face of the furnace body through a hinge, and two handles are fixedly installed on the surface of the box door. The servo motor is stabilized through a fixing groove to prevent the output shaft of the servo motor from shaking during operation. At the same time, the servo motor drives the driving bevel gear and the driven bevel gear to rotate, providing power for the rotation of the rotating shaft. The rotation of the rotating shaft drives the rotation of two spur gears. Since the two spur gears are respectively meshed with the corresponding racks, the two spur gears drive the corresponding first pulling rods to move. The first pulling rod pulls the second pulling rod, and with the cooperation of the rotating seat, the second pulling rod pulls the handle to realize the operation of opening or closing the box door.

[0004] Regarding the above related technologies, the inventor believes that there are the following defects: during the firing process of ceramics in the above device, the ceramics remain stationary inside the furnace body, and there is a high probability of uneven heating of the ceramics after a long time of firing, which may lead to the probability of over-firing and under-firing of the ceramics, thus reducing the quality of the finished ceramics. In addition, the above device takes out the ceramics through the box door, but due to the high temperature inside the furnace body, it is easy for the staff to be scalded when taking out the ceramics.

[0005] Based on this, the present utility model designs a high-temperature refractory ceramic metallization sintering furnace to solve the above problems. Summary of the Utility Model

Specific embodiments

[0029] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0030] The present utility model will be further described below with reference to the embodiments.

[0031] As Figures 1-5 shown, an embodiment of the present application discloses a high-temperature refractory ceramic metallization sintering furnace, including a furnace body 1, support legs 11, support plates 12, mounting plates 13, placing plates 14, a driving device 3, limiting blocks 4, cylinders 5, balls 6, support rods 7 and annular blocks 71. The furnace body 1 is a cuboid structure with a hollow interior, and an installation groove 21 is penetrated and opened on the bottom surface of the furnace body 1. The support legs 11 are rod-shaped structures with a vertical axis, and a plurality of support legs 11 are provided and are arranged in an array on the bottom surface of the furnace body 1. The support plates 12 are rectangular plate-shaped structures, and the support legs 11 are fixedly arranged on the bottom surfaces of the plurality of support legs 11. The mounting plates 13 are circular plate-shaped structures with a vertical axis, and the mounting plates 13 are slidably arranged in the mounting grooves 21. The placing plates 14 are installed on the upper surfaces of the mounting plates 13, and placing grooves 22 are opened on the upper surfaces of the placing plates 14 for placing ceramics to be fired.

[0032] When the staff needs to fire the ceramics, the staff needs to move the mounting plate 13 downward. At this time, the staff places the ceramics to be fired into the placement groove 22. Subsequently, the staff moves the mounting plate 13 upward, so that the mounting plate 13 slides into the mounting groove 21. At this time, the staff turns on the furnace body 1 to fire the ceramics. During this process, the staff needs to start the driving device 3, so that the mounting plate 13 rotates under the action of the driving device 3, so that the placement plate 14 rotates under the action of the mounting plate 13, and then the ceramics being fired rotate under the action of the placement plate 14, thereby reducing the probability of uneven firing of the ceramics during the firing process, and then improving the quality of the finished ceramics. In addition, when the staff needs to take out the fired ceramics, the staff needs to move the mounting plate 13 downward, so that the placement plate 14 and the fired ceramics move downward under the action of the mounting plate 13, so that the fired ceramics move outside the furnace body 1. At this time, the staff takes out the ceramics, thereby reducing the probability of the staff being scalded when taking out the ceramics.

[0033] The driving device 3 is arranged on the support plate 12 and is used to drive the placement plate 14 to rotate. The driving device 3 includes a motor 31, a first gear 32, a rotating rod 33 and a second gear 34. The motor 31 is fixedly arranged on the upper surface of the support plate 12, and the axis of its output shaft is vertical. The first gear 32 is fixedly arranged at the end of the output shaft of the motor 31, and its axis coincides with the axis of the output shaft of the motor 31. The rotating rod 33 is fixedly arranged on the bottom surface of the mounting plate 13, and its axis is vertical. The second gear 34 is fixedly arranged on the bottom surface of the rotating rod 33, and its axis coincides with the axis of the rotating rod 33, and the first gear 32 meshes with the second gear 34.

[0034] When the staff needs to rotate the ceramics being fired, the staff needs to start the motor 31, so that the output shaft of the motor 31 rotates, so that the first gear 32 rotates synchronously with the output shaft of the motor 31 under the action of the output shaft of the motor 31, and then the second gear 34 rotates under the action of the first gear 32, so that the rotating rod 33 rotates under the action of the second gear 34, and then the mounting plate 13 fixedly connected to the rotating rod 33 rotates under the action of the rotating rod 33, so that the placement plate 14 rotates under the action of the mounting plate 13, and then the ceramics being fired rotate under the action of the placement plate 14, thereby reducing the probability of uneven firing of the ceramics during the firing process, and then improving the quality of the finished ceramics.

[0035] The rotating rod 33 includes a rotating sleeve 331 and a rotating sleeve rod 332. The rotating sleeve 331 is a circular rod-shaped structure with an open upper end, and its axis coincides with the axis of the second gear 34. The rotating sleeve 331 is fixedly arranged on the upper surface of the second gear 34. The rotating sleeve rod 332 is a circular rod-shaped structure, and its axis coincides with the axis of the rotating sleeve 331. The rotating sleeve rod 332 is fixedly arranged on the bottom surface of the mounting plate 13, and the rotating sleeve 331 and the rotating sleeve rod 332 slide relative to each other.

[0036] When the staff slides the mounting plate 13 up or down, the rotating sleeve rod 332 slides in the rotating sleeve 331 under the action of the mounting plate 13, thereby reducing the probability of the rotating sleeve 331 moving when the staff slides the mounting plate 13, thus reducing the probability of the second gear 34 moving with the rotating sleeve 331, and further reducing the probability of the second gear 34 separating from the first gear 32, thereby improving the stability of the device.

[0037] A limiting groove 23 is formed on the inner wall of the rotating sleeve 331. The limiting block 4 is a rectangular block structure. The limiting block 4 is slidably arranged in the limiting groove 23, and the limiting block 4 is fixedly connected to the rotating sleeve rod 332.

[0038] When the second gear 34 rotates, the rotating sleeve 331 rotates under the action of the second gear 34, thereby causing the rotating sleeve rod 332 to rotate under the action of the rotating sleeve 331. During this process, the limiting block 4 limits the rotating sleeve rod 332, thereby reducing the probability of relative rotation between the rotating sleeve rod 332 and the rotating sleeve 331 when the rotating sleeve 331 rotates, thus improving the stability of the device. In addition, when the rotating sleeve rod 332 slides, the limiting block 4 slides synchronously with the rotating sleeve rod 332. During this process, when the side wall of the limiting block 4 abuts against the inner wall of the limiting groove 23 (as shown in Figure 4 )), the rotating sleeve rod 332 cannot continue to slide, thereby reducing the probability of the rotating sleeve rod 332 separating from the rotating sleeve 331, thus improving the stability of the device.

[0039] Two cylinders 5 are provided and symmetrically arranged on the upper surface of the support plate 12. The axis of its piston rod is vertical, and the ends of the piston rods of the two cylinders 5 are both connected to the bottom surface of the mounting plate 13.

[0040] When the staff needs to slide the mounting plate 13, the staff needs to start or close the cylinder 5, thereby causing the mounting plate 13 to move up or down under the action of the piston rod of the cylinder 5. During this process, there is no need for the staff to manually slide the mounting plate 13, thereby reducing the work difficulty of the staff. In addition, using the cylinder 5 to slide the mounting plate 13 reduces the probability of the staff being scalded when sliding the mounting plate 13.

[0041] The bottom surface of the mounting plate 13 is provided with a circular groove 24. There are two ball bearings 6 which are rotatably arranged in the circular groove 24, and the two ball bearings 6 are respectively fixed to the piston rods of the two cylinders 5.

[0042] When the mounting plate 13 rotates, the ball bearings 6 rotate relative to the circular groove 24. During this process, the probability that the cylinder 5 blocks the rotating mounting plate 13 when the mounting plate 13 rotates is reduced, thereby improving the stability of the device.

[0043] The support rod 7 is in a round rod shape structure, its axis is vertical, the support rod 7 is fixedly arranged on the upper surface of the support plate 12, and an annular groove 25 is provided on the upper surface of the support rod 7. The annular block 71 is in a circular ring shape structure, its axis coincides with the axis of the support rod 7, the annular block 71 is rotatably arranged in the annular groove 25, and the annular block 71 is fixed to the second gear 34.

[0044] When the second gear 34 rotates, the annular block 71 rotates synchronously with the second gear 34 under the action of the second gear 34. During this process, the annular block 71 limits the second gear 34, thereby reducing the probability that the second gear 34 shakes when rotating, and thus improving the stability of the device. In addition, the second gear 34 can also support the second gear 34 and the rotating sleeve rod 332, thereby further reducing the probability that the second gear 34 shakes.

[0045] In order to improve the sealing performance during the firing process, a sealing ring 8 is fixedly arranged on the bottom surface of the mounting plate 13, and a high-temperature resistant coating is applied to the surface of the sealing ring 8. The sealing ring 8 reduces the probability of leakage inside the furnace body 1 during the firing process, thereby improving the sealing performance of the device. In addition, the high-temperature resistant coating applied to the surface of the sealing ring 8 extends the service life of the sealing ring 8.

[0046] In this embodiment, the working principle of a high-temperature refractory ceramic metallization sintering furnace is as follows: When the staff needs to fire the ceramic, the staff needs to move the mounting plate 13 downward. At this time, the staff places the ceramic to be fired into the placement groove 22. Subsequently, the staff moves the mounting plate 13 upward, and then makes the mounting plate 13 slide into the mounting groove 21. At this time, the staff turns on the furnace body 1 to fire the ceramic. During this process, the staff needs to start the motor 31, and then make the output shaft of the motor 31 rotate, so that the first gear 32 rotates synchronously with the output shaft of the motor 31 under the action of the output shaft of the motor 31. Then, the second gear 34 rotates under the action of the first gear 32, so that the rotating rod 33 rotates under the action of the second gear 34. Further, the mounting plate 13 fixed to the rotating rod 33 rotates under the action of the rotating rod 33, so that the placement plate 14 rotates under the action of the mounting plate 13, and then the ceramic being fired rotates under the action of the placement plate 14, thereby reducing the probability of uneven firing of the ceramic during the firing process, and further improving the quality of the finished ceramic. In addition, when the staff needs to take out the fired ceramic, the staff needs to start the cylinder 5, and then make the mounting plate 13 move downward under the action of the piston rod of the cylinder 5, so that the placement plate 14 and the fired ceramic move downward under the action of the mounting plate 13, so that the fired ceramic moves outside the furnace body 1. At this time, the staff takes out the ceramic, thereby reducing the probability of the staff being scalded when taking out the ceramic.
