Abstract
Description
Technical Field
[0001] The invention relates to the technical field of ceramic sintering, in particular to a novel rotary gas pressure sintering furnace. Background Art
[0002] Ceramic products are usually processed into green bodies by methods such as molding and cold isostatic pressing (CIP), and then sintered under a certain temperature and pressure. The application of a certain pressure under high temperature conditions inhibits the nitride ceramics that are easy to decompose under normal pressure, thereby promoting their sintering densification.
[0003] At present, the rotary sintering furnaces on the market only have heating wires inside the furnace body and a turntable at the bottom of the furnace body. The ceramic embryo is then placed on the turntable for firing. This rotary sintering method has the following disadvantages:
[0004] First, because the turntable is located in the middle of the furnace, the distances between the upper and lower ends of the ceramic embryo and the edge of the ceramic embryo shell and the heating wire are inconsistent, which can easily cause uneven heating. This can easily affect the uniformity of density and crystal structure of products fired in the same furnace, such as ceramic balls and sticks, thus affecting the quality of the fired products.
[0005] Second, the area of the turntable at the bottom of the furnace is limited, and multiple batches of ceramics cannot be fired simultaneously;
[0006] Third, although the turntable in the sintering furnace can rotate axially, the ceramic body placed on it cannot move or change its orientation, which is not conducive to obtaining products with more uniform structure and performance.
[0007] Therefore, we proposed a new type of rotary gas pressure sintering furnace. Summary of the Invention

When the extension frame 72 at the right end of the L-shaped dial 71 is tilted, the dial wheel 73 on the extension frame 72 moves to the bottom of the discharge rack 9. When the rotating grate 6 rotates, the dial wheel 73 on the extension frame 72 can dial the discharge rack 9 The top of the unloading rack 9 rotates along the fixed axis 63, thereby causing the ceramic blanks in the unloading rack 9 to roll. The tops of the left and right sides of the unloading rack 9 are respectively welded with inclined baffles 19.

The input end of the controller 23 is electrically connected to the output end of the digital pressure gauge 13 and the external power supply.
[0032] The working principle of the present invention is as follows: when in use, the furnace cover 18 is opened, and the second motor 51 is started through the controller 3, so that the second motor 51 drives the first sprocket 52 to rotate, and the first sprocket 52 drives the second sprocket 53 to rotate through the transmission chain 54, thereby causing the threaded rod 55 to rotate synchronously, and the threaded rod 55 drives the first guide block 57 to push the rotating disk frame 1 61 to move toward the fixed block 56, so that the guide wheel 66 on the second guide block 65 at the bottom of the rotating disk frame 1 61 slides along the track 14, and under the action of the fixed shaft 63 and the connecting rod 67, the rotating disk frame 1 61 is rotated. The second rotating disc rack 62 is pushed out of the furnace body 1. At this time, the staff can place the ceramic ball embryos or ceramic sticks that need to be fired in the discharge rack 9 respectively. When placing the ceramic blanks, the second rotating disc rack 62 can be rotated by the handle 68 to drive the rotating disc rack 1 61 to rotate along the second guide block 65 through the fixed shaft 63, so that the staff can place the ceramic blanks in all the discharge racks 9. After the ceramic blanks are placed, the second motor 51 is controlled to drive the first sprocket 52 to reverse, and the rotating furnace rack 6 is moved to the inside of the inner tank 2. By observing The setting of the window 64 makes it convenient for the staff to adjust the direction of the plug-in slot 69 through the handle 68, so that the plug-in slot 69 and the plug-in rod 45 are plugged in and matched. Then the furnace cover 18 is closed and the furnace cover 18 is locked by the locking screw 20 and the locking nut 21. At the beginning of sintering, the heating temperature of the electric heating tube 10 is controlled by the temperature controller 11, and the first motor 41 is started at the same time, so that the first motor 41 drives the driven gear 44 to rotate through the driving gear 42, so that the gear 44 drives the plug-in rod 45 to rotate through the rotating shaft 43. , thereby driving the rotary furnace frame 6 to rotate as a whole, so that the ceramic blank in the discharge rack 9 can be heated evenly. Since the ceramic blank is easy to decompose nitride ceramics under a certain pressure to suppress normal pressure during the firing process, its sintering and densification are promoted. The air inlet pipe 15 can be connected to the external air pressure pipeline so that it can pressurize the interior of the inner tank 2. By observing the digital pressure gauge 13 on the connecting pipe 12, the air pressure inside the inner tank 2 can be detected in real time. By controlling the electric valve 16 on the exhaust pipe 17, the air pressure inside the inner tank 2 can be reduced.During the middle stage of sintering, when the ceramic blank is relatively dense and not easily deformed, the second motor 51 can be used to drive the rotary grate 6 toward the partition 3. As the rotary grate 6 moves, the insertion slot 69 moves along the insertion rod 45 toward its left end, and the bottom of the rotary disc frame 1 61 pushes the L-shaped dial 71, causing the L-shaped dial 71 to rotate along the pin on the U-shaped support frame 8. When the extension frame 72 at the right end of the L-shaped dial 71 tilts up, the dial wheel 73 on the extension frame 72 moves to the bottom of the unloading rack 9. As the rotary grate 6 rotates, the dial wheel 73 on the extension frame 72 can move the bottom of the unloading rack 9, causing the top of the unloading rack 9 to rotate along the fixed axis 63, thereby causing the ceramic blank in the unloading rack 9 to roll. By changing the position of the ceramic blank, the ceramic blank is moved, which is conducive to obtaining a ceramic product with more uniform structure and properties.
