Description

Technical Field

[0001] The present invention relates to the technical field of alumina ceramic ovens, and particularly to an oven for producing high-performance alumina ceramics. Background Art

[0002] In the field of high-end manufacturing, alumina ceramics are widely used in industries such as aerospace, electronics, and electrical engineering due to their excellent properties such as high hardness, high temperature resistance, and good insulation. With the expansion of application scenarios, the market's requirements for their quality and production efficiency have increased. Drying, as a key link in the production of alumina ceramics, is crucial for product performance and yield. Therefore, developing a suitable high-performance oven is of great significance for ensuring production and meeting market demands.

[0003] Currently, most of the ovens used in the production of alumina ceramics on the market have single and backward functions, simply placing the alumina ceramics inside for static drying. This lack of scientific design in the drying method causes uneven heating of the ceramic blank during the drying process, frequent occurrences of local overheating or overcooling, greatly reducing the drying efficiency and increasing production costs. Moreover, after drying is completed, there is still a very high temperature remaining inside the oven. Once the operator rashly opens the oven, the scalding hot air gushing out instantly will hit the face, not only causing extreme discomfort but also very likely causing safety accidents such as burns, posing a great potential safety hazard to the operator's personal safety, and at the same time affecting the continuity and stability of production. Therefore, we propose an oven for producing high-performance alumina ceramics. Summary of the Invention

[0007] Preferably, one side of the baffle is in contact with the outer wall of the drying box. One end of the rotating cylinder penetrates to the outside of the opening and is movably connected to the bearing fixedly installed at the center of one side of the baffle. The second motor is fixedly connected with a driving shaft through the output end on its one side. One end of the driving shaft is fixedly connected to the center of one side of the driving gear. One side of the rotating rod is movably connected to the bearing fixedly installed at the bottom position on one side of the moving plate. The other side of the rotating rod sequentially penetrates the inside of the moving plate, the baffle, the rotating cylinder and the placing mesh box and is movably connected to the bearing fixedly installed at the center of one side inside the placing mesh box.

[0008] Preferably, the two blowers arranged up and down are respectively fixedly installed with wind covers through the air outlets opened at the bottom and the top. Second chutes are respectively opened at the centers of the inner top and the inner bottom of the drying box. The centers of the tops and the bottoms of the two screw nuts are fixedly connected with second sliders. The tops and the bottoms of the two second sliders respectively extend into the interiors of the two second chutes and are slidably connected to the inner walls of the second chutes.

[0009] Preferably, the third motor is fixedly connected with a driving shaft through the output end on its one side. One end of the driving shaft penetrates into the interior of the transmission box and is fixedly connected to one side of the rotating column. A bearing is fixedly installed at the center of one side of the inner wall of the drying box. One end of the rotating column sequentially penetrates the outside of the transmission box, the drying box and the bearing. The outer wall of the rotating column is fixedly connected to the inner ring of the bearing. One end of the hexagonal insertion rod penetrates into the interior of the hexagonal insertion groove and is in contact with the inner wall of the hexagonal insertion groove. One ends of the two reciprocating lead screws are respectively movably connected to the bearings fixedly installed at the top position and the bottom position on one side inside the drying box. The other ends of the two reciprocating lead screws sequentially penetrate the drying box and the transmission box and are movably connected to the bearings fixedly installed at the top position and the bottom position on one side inside the transmission box.

[0010] Preferably, protective nets are fixedly installed at the bottoms and the tops corresponding to the two heating wires inside the drying box.

[0011] Preferably, an exhaust groove is opened at one side of the top of the front surface of the drying box. A material pipe is fixedly communicated with the center of the top of the placing mesh box. A screw cap is threadedly connected to the upper end of the material pipe.

[0012] An operation method for an oven used in the production of high-performance alumina ceramics includes the following steps: Step 1, put the alumina ceramics to be dried into the placing mesh box through the material pipe fixedly communicated with the center of the top of the placing mesh box, ensure that the ceramics are evenly distributed in the placing mesh box. After the feeding is completed, tighten the screw cap at the upper end of the material pipe to prevent the ceramics from spilling during the subsequent drying process and also avoid foreign impurities from entering and affecting the drying effect.

[0013] Step 2: Start the first motor. The first motor drives the threaded rod to rotate through the output shaft connected to one side of it. Since the internally threaded plate is threadedly connected to the threaded rod, and the first slider at the center of the top of the internally threaded plate slides in the first chute at the center of the inner top of the connecting frame, the internally threaded plate will move along the threaded rod. When the internally threaded plate moves, it drives the moving plate to move together through the first connecting block. The support wheels at the front end and rear end of the bottom surface of the moving plate roll on the inner bottom of the connecting frame, providing support for the moving plate and assisting it to move smoothly. As the moving plate moves, it drives the baffle to approach the drying box. One end of the rotating cylinder on one side of the baffle penetrates the opening on one side of the drying box and is movably connected to the bearing fixedly installed at the center of one side of the baffle until the baffle is in close contact with the outer wall of the drying box. At this time, the placement mesh box is moved into the drying box, and the hexagonal insertion rod is inserted into the hexagonal insertion slot.

[0014] Step 3: Turn on the fan and the heating wire. After the heating wire is powered on, it generates heat. The fan evenly blows the hot air generated by the heating wire towards the alumina ceramics in the placement mesh box through the air hood at the air outlet to dry the ceramics. At the same time, start the third motor. The third motor drives the rotating column to rotate through the drive shaft at its output end. One end of the hexagonal insertion rod on the rotating column is inserted into the hexagonal insertion slot of the socket, so that the rotating column can drive the placement mesh box to rotate, enabling the ceramics to continuously change positions during the drying process to promote uniform heating. In addition, the driving sprocket on the surface of the rotating column drives the driven sprocket on the surface of the reciprocating screw rod to rotate through the chain, so that the two reciprocating screw rods rotate. Since the screw nut is threadedly connected to the reciprocating screw rod, and the second sliders at the top and bottom of the screw nut slide in the second chutes at the centers of the inner top and inner bottom of the drying box, the two screw nuts will drive the two fans to move reciprocally at the same time, further ensuring that the hot air can evenly cover the ceramics and improving the drying efficiency and quality.

[0015] Step 4: When the drying of the alumina ceramics is completed, turn off the fan, the heating wire, the third motor, and the related rotating and stirring mechanisms. Start the first motor again and make it rotate in the reverse direction, driving the threaded rod to rotate in the reverse direction, so that the internally threaded plate, the moving plate, and the baffle move in the reverse direction, moving the placement mesh box out of the drying box. After it is taken out, open the screw cap of the material pipe at the top of the placement mesh box and take out the dried alumina ceramics to complete the entire drying process.

[0016] Compared with the prior art, the beneficial effects of the present invention are: The oven for producing high-performance alumina ceramics, through the design of the connecting frame, the first motor, the threaded rod, the internally threaded plate, the moving plate, the second connecting block and the baffle plate, after the drying is completed, there is no need for the operator to directly approach the high-temperature oven to operate and take out the materials. The first motor can be used to drive the threaded rod to rotate, so that the internally threaded plate drives the moving plate to move outwards, and then the placing mesh box can be smoothly moved out of the drying box. In this process, the operator keeps a safe distance from the inside of the high-temperature oven, effectively avoiding the discomfort and scalding risk caused by the suddenly gushing hot air to the operator, effectively ensuring the personal safety of the operator. At the same time, there is no need to wait for the temperature inside the oven to naturally decrease, saving a lot of time, ensuring the continuity and stability of production, significantly improving the production efficiency. The design of the rotating cylinder, the second motor, the rotating rod, the driving gear, the driven gear, the stirring rod, the third motor, the rotating column, the plugging seat, the hexagonal plugging groove, the hexagonal plugging rod and the placing mesh box, during the drying process, the third motor drives the rotating column to rotate. With the precise cooperation of the hexagonal plugging rod and the hexagonal plugging groove, it can stably drive the placing mesh box to rotate, so that the alumina ceramics continuously change positions in the drying box, avoiding local overheating or overcooling phenomena, greatly promoting the uniform heating of the ceramic blank, and effectively improving the drying quality. At the same time, the second motor drives the rotating rod to rotate through the meshing transmission of the driving gear and the driven gear, and then the stirring rod stirs the alumina ceramics in the placing mesh box. This dynamic stirring method further ensures the full contact between the ceramics and the hot air, speeds up the drying speed, significantly improves the drying efficiency, shortens the production cycle, and reduces the production cost, creating higher economic benefits for the enterprise. The design of the reciprocating lead screw, the lead screw nut, the fan, the heating wire, the driving sprocket, the driven sprocket and the chain, during the drying operation, the heating wire is energized to generate heat, and after the fan is started, the hot air is evenly blown towards the alumina ceramics in the placing mesh box. When the third motor drives the rotating column to rotate, the driving sprocket on the rotating column synchronously drives the driven sprockets on the two reciprocating lead screws to rotate through the chain, so that the two reciprocating lead screws rotate simultaneously. Since the two lead screw nuts are respectively threadedly connected to the corresponding reciprocating lead screws, and under the limiting action of the second slider and the second chute, the two lead screw nuts will synchronously drive the fans installed on them to move reciprocally. This design enables the hot air to be evenly distributed in the drying box in the horizontal and vertical directions, avoiding the problems of local overheating of the ceramics or uneven drying caused by the concentration of hot air, ensuring the uniform heating of the alumina ceramics during the drying process, further improving the drying quality and efficiency, and at the same time effectively reducing the risk of ceramic quality defects caused by local overheating, ensuring the consistency and stability of the product.

A hexagonal plug rod 31 is fixedly connected to one end of the rotating column 28, and a hexagonal plug groove 30 is opened in the center of one side of the plug seat 29. Driving sprockets 35 are fixedly installed on both sides of the surface of the rotating column 28. Driven sprockets 36 are fixedly installed on the top and bottom of the two driving sprockets 35 respectively on the surfaces of the two reciprocating screw rods 20. The two driving sprockets 35 are respectively connected to the two driven sprockets 36 through chains 37. The inside of the drying box 1 is fixedly installed with heating wires 33 at the bottom and top corresponding to the two fans 22 respectively.

[0021] The first motor 4 is fixedly connected with an output shaft through the output end on one side thereof. One end of the output shaft penetrates to the outside of the connecting frame 3 and is fixedly connected with one end of the threaded rod 5. The other end of the threaded rod 5 is movably connected with a bearing fixedly installed at a position near the top on one side of the drying box 1. A first sliding groove 7 is formed in the center of the inner top of the connecting frame 3. The center of the top of the internally threaded plate 6 is fixedly connected with a first sliding block 8. The top of the first sliding block 8 extends into the interior of the first sliding groove 7 and is slidably connected with the inner wall of the first sliding groove 7. The front ends and the rear ends at the bottom of the front surface of the moving plate 10 are both fixedly connected with supporting wheels 11. The bottoms of the two supporting wheels 11 are both in contact with the bottom inside the connecting frame 3. The first motor 4 drives the output shaft to drive the threaded rod 5 to rotate, providing power for the movement of the moving plate 10. The cooperation of the first sliding groove 7 and the first sliding block 8 plays a limiting role on the internally threaded plate 6, enabling it to move only along the axial direction of the threaded rod 5, thereby driving the moving plate 10 to move smoothly. The supporting wheels 11 provide support for the moving plate 10, reducing the friction during movement, ensuring the smooth movement of the moving plate 10, guaranteeing that the placement net box 32 can accurately enter and exit the drying box 1, realizing automatic loading and unloading, improving production efficiency and ensuring operation safety.

[0022] One side of the baffle plate 13 is in contact with the outer wall of the drying box 1. One end of the rotating cylinder 14 penetrates to the outside of the opening 26 and is movably connected with a bearing fixedly installed at the center on one side of the baffle plate 13. The second motor 15 is fixedly connected with a driving shaft through the output end on one side thereof. One end of the driving shaft is fixedly connected with the center on one side of the driving gear 17. One side of the rotating rod 16 is movably connected with a bearing fixedly installed at a position near the bottom on one side of the moving plate 10. The other side of the rotating rod 16 sequentially penetrates the moving plate 10, the baffle plate 13, the rotating cylinder 14 and the interior of the placement net box 32 and is movably connected with a bearing fixedly installed at the center on one side inside the placement net box 32. The baffle plate 13 is in contact with the outer wall of the drying box 1, playing a sealing role after the placement net box 32 enters the drying box 1 and reducing heat dissipation. The rotating cylinder 14 is movably connected with the baffle plate 13 through a bearing, ensuring both the stability of the rotating cylinder 14 and facilitating the rotation of the placement net box 32. The second motor 15 drives the driving gear 17 to rotate through the driving shaft, and then drives the rotating rod 16 to rotate. The rotating rod 16 drives the stirring rod 19 inside the placement net box 32 to stir the alumina ceramics, making the ceramics heat more evenly and improving the drying quality. At the same time, this design makes the entire transmission structure compact and reasonable, and each component works together to ensure the stable progress of the drying process.

[0023] Two blowers 22 arranged vertically are respectively fixedly installed with wind covers 23 through air outlets opened at the bottom and the top. Second chutes 24 are opened at the centers of the inner top and the inner bottom of the drying box 1. The centers of the tops and the bottoms of the two lead screw nuts 21 are fixedly connected with second sliders 25 respectively. The tops and the bottoms of the two second sliders 25 extend into the two second chutes 24 respectively and are slidably connected with the inner walls of the second chutes 24. The wind covers 23 make the hot air blown out by the blowers 22 more concentrated and evenly blown onto the alumina ceramics in the placement net box 32, improving the drying efficiency. The cooperation of the second chutes 24 and the second sliders 25 plays a limiting role on the lead screw nuts 21, enabling them to only move axially along the reciprocating lead screws 20, thereby driving the blowers 22 to reciprocate, expanding the coverage range of the hot air, avoiding local overheating or uneven drying, ensuring the consistent overall drying quality of the alumina ceramics, and enhancing the drying effect.

[0024] A third motor 27 is fixedly connected with a drive shaft through an output end on one side thereof. One end of the drive shaft penetrates into the interior of the transmission box 2 and is fixedly connected with one side of a rotating column 28. A bearing is fixedly installed at the center of one side of the inner wall of the drying box 1. One end of the rotating column 28 sequentially penetrates the transmission box 2, the drying box 1, and the outside of the bearing. The outer wall of the rotating column 28 is fixedly connected with the inner ring of the bearing. One end of a hexagonal insertion rod 31 penetrates into the interior of a hexagonal insertion groove 30 and is in contact with the inner wall of the hexagonal insertion groove 30. One ends of the two reciprocating lead screws 20 are movably connected with bearings fixedly installed at positions near the top and near the bottom on one side inside the drying box 1 respectively. The other ends of the two reciprocating lead screws 20 sequentially penetrate the drying box 1 and the transmission box 2 and are movably connected with bearings fixedly installed at positions near the top and near the bottom on one side inside the transmission box 2 respectively. The third motor 27 drives the rotating column 28 to rotate through the drive shaft. The hexagonal insertion rod 31 at one end of the rotating column 28 cooperates with the hexagonal insertion groove 30 to transmit power to the placement net box 32, realizing the rotation of the placement net box 32, enabling the alumina ceramics to continuously change positions during the drying process, and promoting uniform heating. The reciprocating lead screws 20 are connected with the drying box 1 and the transmission box 2 through bearings, ensuring their stable rotation, providing support for the reciprocating movement of the blowers 22, enabling the components of the entire drying system to work together, and guaranteeing the stability and high efficiency of the drying process.

[0025] Protective nets 34 are fixedly installed at the bottoms and the tops corresponding to the two heating wires 33 inside the drying box 1 respectively. The protective nets 34 can prevent the alumina ceramics or other sundries from contacting the heating wires 33, avoid damage to the heating wires 33 due to collision, extend the service life of the heating wires 33, and at the same time ensure the safe operation inside the drying box 1, prevent safety accidents caused by damage to the heating wires 33, and ensure the normal progress of the drying process.

[0026] One side at the top of the front surface of the drying oven 1 is provided with an exhaust groove. The center of the top of the placing mesh box 32 is fixedly communicated with a material pipe. The upper end of the material pipe is screwed with a rotary cover. The exhaust groove is used for discharging the water vapor generated during drying. By opening the rotary cover, it can be used to feed materials into the material pipe. At the same time, the material pipe is used to discharge the dried materials.

[0027] An operation method for an oven used in the production of high-performance alumina ceramics includes the following steps: Step 1, put the alumina ceramics to be dried into the placing mesh box 32 through the material pipe fixedly communicated with the center of the top of the placing mesh box 32, ensure that the ceramics are evenly distributed in the placing mesh box 32. After the feeding is completed, tighten the rotary cover at the upper end of the material pipe to prevent the ceramics from spilling during the subsequent drying process, and at the same time avoid external impurities from entering and affecting the drying effect.

[0028] Step 2, start the first motor 4. The first motor 4 drives the threaded rod 5 to rotate through the output shaft connected to one side of its output end. Since the internal threaded plate 6 is threadedly connected to the threaded rod 5, and the first slider 8 at the center of the top of the internal threaded plate 6 slides in the first chute 7 at the center of the inner top of the connecting frame 3, the internal threaded plate 6 will move along the threaded rod 5. When the internal threaded plate 6 moves, it drives the moving plate 10 to move together through the first connecting block 9. The supporting wheels 11 at the front end and the rear end of the bottom of the front surface of the moving plate 10 roll on the inner bottom of the connecting frame 3 to provide support for the moving plate 10 and assist its smooth movement. As the moving plate 10 moves, it drives the baffle 13 to approach the drying oven 1. One end of the rotating cylinder 14 on one side of the baffle 13 penetrates through the opening 26 on one side of the drying oven 1 and is movably connected to the bearing fixedly installed at the center of one side of the baffle 13 until the baffle 13 is in close contact with the outer wall of the drying oven 1. At this time, the placing mesh box 32 is moved into the drying oven 1, and the hexagonal plugging rod 31 is inserted into the hexagonal plugging groove 30.

[0029] Step 3: Turn on the blower 22 and the heating wire 33. After the heating wire 33 is powered on, it generates heat. The blower 22 evenly blows the hot air generated by the heating wire 33 towards the alumina ceramics in the placement mesh box 32 through the air hood 23 at the air outlet to dry the ceramics. Meanwhile, start the third motor 27. The third motor 27 drives the rotating column 28 to rotate through the drive shaft at its output end. The hexagonal plugging rod 31 at one end of the rotating column 28 is inserted into the hexagonal plugging groove 30 of the plugging seat 29, enabling the rotating column 28 to drive the placement mesh box 32 to rotate, so that the ceramics continuously change positions during the drying process, promoting uniform heating. In addition, the driving sprocket 35 on the surface of the rotating column 28 drives the driven sprocket 36 on the surface of the reciprocating lead screw 20 to rotate through the chain 37, thereby causing the two reciprocating lead screws 20 to rotate. Since the lead screw nut 21 is threadedly connected to the reciprocating lead screw 20, and the second sliders 25 at the top and bottom of the lead screw nut 21 slide in the second chute 24 at the center of the inner top and inner bottom of the drying box 1, the two lead screw nuts 21 will simultaneously drive the two blowers 22 to reciprocate, further ensuring that the hot air can evenly cover the ceramics and improving the drying efficiency and quality.

[0030] Step 4: When the drying of the alumina ceramics is completed, turn off the blower 22, the heating wire 33, the third motor 27 and the related rotating and stirring mechanisms. Start the first motor 4 again and make it rotate in the reverse direction, driving the threaded rod 5 to rotate in the reverse direction, thereby causing the internally threaded plate 6, the moving plate 10 and the baffle 13 to move in the reverse direction, moving the placement mesh box 32 out of the drying box 1. After it is moved out, open the screw cap of the material pipe at the top of the placement mesh box 32 and take out the dried alumina ceramics to complete the entire drying process.

[0031] In summary, for the oven used in the production of high-performance alumina ceramics, through the design of the connecting frame 3, the first motor 4, the threaded rod 5, the internally threaded plate 6, the moving plate 10, the second connecting block 12 and the baffle 13, after the drying is completed, there is no need for the operator to directly approach the high-temperature oven to operate and take out the materials. The first motor 4 can be used to drive the threaded rod 5 to rotate, so that the internally threaded plate 6 drives the moving plate 10 to move outwards, and then the placement mesh box 32 can be smoothly moved out of the drying box 1. During this process, the operator keeps a safe distance from the inside of the high-temperature oven, effectively avoiding the discomfort and scalding risk caused by the suddenly gushing hot air to the operator, effectively ensuring the personal safety of the operator. At the same time, there is no need to wait for the temperature inside the oven to naturally decrease, saving a lot of time, ensuring the continuity and stability of production, significantly improving the production efficiency. Through the design of the rotating cylinder 14, the second motor 15, the rotating rod 16, the driving gear 17, the driven gear 18, the stirring rod 19, the third motor 27, the rotating column 28, the socket 29, the hexagonal socket groove 30, the hexagonal socket rod 31 and the placement mesh box 32, during the drying process, the third motor 27 drives the rotating column 28 to rotate. With the precise cooperation of the hexagonal socket rod 31 and the hexagonal socket groove 30, it can stably drive the placement mesh box 32 to rotate, so that the alumina ceramics continuously change their positions in the drying box 1, avoiding local overheating or overcooling phenomena, greatly promoting the uniform heating of the ceramic blank, and effectively improving the drying quality. At the same time, the second motor 15 drives the rotating rod 16 to rotate through the meshing transmission of the driving gear 17 and the driven gear 18, and then the stirring rod 19 stirs the alumina ceramics in the placement mesh box 32. This dynamic stirring method further ensures the full contact between the ceramics and the hot air, speeds up the drying speed, significantly improves the drying efficiency, shortens the production cycle, and reduces the production cost, creating higher economic benefits for the enterprise. Through the design of the reciprocating screw rod 20, the screw nut 21, the fan 22, the heating wire 33, the driving sprocket 35, the driven sprocket 36 and the chain 37, during the drying operation, the heating wire 33 is energized to generate heat, and after the fan 22 is started, the hot air is evenly blown towards the alumina ceramics in the placement mesh box 32. When the third motor 27 drives the rotating column 28 to rotate, the driving sprocket 35 on the rotating column 28 synchronously drives the driven sprockets 36 on the two reciprocating screw rods 20 to rotate through the chain 37, so that the two reciprocating screw rods 20 rotate simultaneously. Since the two screw nuts 21 are respectively threadedly connected to the corresponding reciprocating screw rods 20, and under the limiting action of the second slider 25 and the second chute 24, the two screw nuts 21 will respectively drive the fans 22 installed on them to move reciprocally synchronously. This design enables the hot air to be evenly distributed in the drying box 1 in the horizontal and vertical directions, avoiding the problems of local overheating of the ceramics or uneven drying caused by the concentration of hot air, ensuring the uniform heating of the alumina ceramics during the drying process, further improving the drying quality and efficiency, and at the same time effectively reducing the risk of ceramic quality defects caused by local overheating, ensuring the consistency and stability of the product.

The center of the top of the placing net box (32) is fixedly communicated with a material pipe, and the upper end of the material pipe is screwed with a rotary cover.

8. The operation method of an oven for producing high-performance alumina ceramics according to any one of claims 1-7, characterized in that, It includes the following steps: Step 1: Put the alumina ceramic to be dried into the placing net box (32) through the material pipe fixedly communicated with the center of the top of the placing net box (32), ensure that the ceramics are evenly distributed in the placing net box (32). After the feeding is completed, tighten the rotary cover at the upper end of the material pipe to prevent the ceramics from spilling during the subsequent drying process, and at the same time avoid foreign impurities from entering and affecting the drying effect. Step 2: Start the first motor (4). The first motor (4) drives the threaded rod (5) to rotate through the output shaft connected to one side of its output end. Since the internal threaded plate (6) is threadedly connected to the threaded rod (5), and the first slider (8) at the center of the top of the internal threaded plate (6) slides in the first chute (7) at the center of the inner top of the connecting frame (3), the internal threaded plate (6) will move along the threaded rod (5). When the internal threaded plate (6) moves, it drives the moving plate (10) to move together through the first connecting block (9). The supporting wheels (11) at the front end and the rear end of the bottom of the front surface of the moving plate (10) roll in the inner bottom of the connecting frame (3) to provide support for the moving plate (10) and assist it to move smoothly. As the moving plate (10) moves, it drives the baffle (13) to approach the drying box (1). One end of the rotating cylinder (14) on one side of the baffle (13) penetrates through the opening (26) on one side of the drying box (1) and is movably connected to the bearing fixedly installed at the center of one side of the baffle (13) until the baffle (13) is in close contact with the outer wall of the drying box (1). At this time, the placing net box (32) is moved into the drying box (1), and the hexagonal inserting rod (31) is inserted into the hexagonal inserting groove (30). Step 3: Turn on the fan (22) and the heating wire (33). After the heating wire (33) is powered on, it generates heat. The fan (22) evenly blows the hot air generated by the heating wire (33) towards the alumina ceramics in the placing net box (32) through the air hood (23) at the air outlet to dry the ceramics. At the same time, start the third motor (27). The third motor (27) drives the rotating column (28) to rotate through the driving shaft at its output end. One end of the hexagonal inserting rod (31) on the rotating column (28) is inserted into the hexagonal inserting groove (30) of the inserting seat (29), so that the rotating column (28) can drive the placing net box (32) to rotate, enabling the ceramics to continuously change positions during the drying process to promote uniform heating. In addition, the driving sprocket (35) on the surface of the rotating column (28) drives the driven sprocket (36) on the surface of the reciprocating lead screw (20) to rotate through the chain (37), so that the two reciprocating lead screws (20) rotate. Since the lead screw nut (21) is threadedly connected to the reciprocating lead screw (20), and the second sliders (25) at the top and bottom of the lead screw nut (21) slide in the second chutes (24) at the centers of the inner top and the inner bottom of the drying box (1), the two lead screw nuts (21) will simultaneously drive the two fans (22) to reciprocate, further ensuring that the hot air can evenly cover the ceramics and improving the drying efficiency and quality. Step 4: After the alumina ceramic is dried, turn off the blower (22), heating wire (33), third motor (27) and related rotating and stirring mechanisms, and start the first motor (4) again to rotate it in the reverse direction, driving the threaded rod (5) to rotate in the reverse direction, so that the internally threaded plate (6), moving plate (10) and baffle plate (13) move in the reverse direction, moving the placement mesh box (32) out of the drying box (1). After removal, open the screw cap of the feed pipe at the top of the placement mesh box (32) and take out the dried alumina ceramic to complete the entire drying process.
