Description

Technical Field

[0001] This utility model relates to the field of silicon carbide ceramic sintering technology, specifically to an environmentally friendly silicon carbide ceramic sintering device. Background Technology

[0002] Silicon carbide ceramics are an advanced ceramic material containing silicon and carbon. They are mainly made from high-purity silicon carbide powder through a precision process. Silicon carbide ceramics have a variety of excellent physical and chemical properties, which makes them widely used in many fields.

[0003] In the processing of silicon carbide ceramics, the final step is to sinter the workpiece. During the sintering process, chemical bonds are formed between the powder particles to achieve the fusion and densification of the material. A sintering furnace is required for processing during sintering, but existing sintering furnaces have certain inconveniences in use.

[0004] First, the existing sintering furnaces generally have poor environmental performance when in use. When the silicon carbide ceramics are taken out after sintering, a certain amount of harmful gases such as carbon dioxide and nitrogen oxides will be released in the furnace during the opening process, which can easily cause harm to the health of workers and the air environment.

[0005] Secondly, in existing sintering furnaces, the workpieces are usually placed fixed inside the furnace during use. During sintering, the workpieces are not easily heated evenly, which can affect the sintering efficiency. Furthermore, it is inconvenient to remove the workpieces after sintering.

[0006] Therefore, we propose an environmentally friendly silicon carbide ceramic sintering device. Utility Model Content

[0007] The main objective of this invention is to provide an environmentally friendly silicon carbide ceramic sintering device that can effectively solve the problems in the background art.

[0010] Preferably, a purification filter cotton is detachably connected to the middle of the air filter plate, and a rubber plug is provided on the upper outer surface of the air filter plate, and a rubber plug is provided on the upper outer surface of the rubber plug.

[0011] Preferably, the fixed frame is fixedly connected to the first drive motor via a connecting frame, and the output end of the first drive motor is connected to the bottom end of the turntable.

[0013] Preferably, the exhaust fan is fixedly connected to the purification filter cartridge via a fixing rod, and a limiting hole is provided in the middle of the positioning plate.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The installed purification filter cartridge can draw air from the sintering furnace through an internal exhaust fan, allowing the gas inside the furnace to be discharged through the electromagnetic butterfly valve and the purification filter cartridge. As the gas passes through the purification filter cartridge, the filter plate inside the cartridge filters the gas through the purification filter cotton, preventing harmful gases from the furnace from harming workers' health and the air environment, resulting in high environmental friendliness during use. The first drive motor can drive the turntable to rotate, which in turn drives the cylinder to rotate. The cylinder can raise and lower the second drive motor through a connecting horizontal plate, indirectly opening the sealing cover through the second drive motor. After opening the sealing cover, it is easy to remove the sintered workpiece along with the removed shaft. The second drive motor can drive the shaft to rotate, allowing silicon carbide workpieces to be placed on the carrier plate on the outer wall of the shaft. When the shaft rotates, the workpieces can be rotated through the carrier plate, allowing the workpieces to be heated quickly and improving sintering efficiency. Attached Figure Description

When the gas passes through the purification filter cartridge 11, the gas filter plate 20 inside the purification filter cartridge 11 filters the gas through the purification filter cotton 21, which can prevent harmful gases in the furnace from harming the health of workers and the air environment. It has a high degree of environmental protection when in use.

[0025] In one embodiment of this utility model, an exhaust fan 17 is provided in the middle of the purification filter cartridge 11, a fixing rod 18 is provided between the exhaust fan 17 and the purification filter cartridge 11, a positioning piece 19 is fixedly connected to the inner wall of the purification filter cartridge 11, and a filter plate 20 is provided below the positioning piece 19.

[0027] In another embodiment of this utility model, the fixed frame 4 is fixedly connected to the first drive motor 5 through the connecting frame 6. The output end of the first drive motor 5 is connected to the bottom end of the turntable 3. When in use, the first drive motor 5 can drive the turntable 3 to rotate, which can drive the cylinder 7 to rotate. The cylinder 7 can raise and lower the second drive motor 9 through the connecting horizontal plate 12, and indirectly open the sealing cover 8 through the second drive motor 9. After opening the sealing cover 8, it is convenient to remove the shaft 13 together, which is convenient for taking out the sintered workpiece. When in use, the second drive motor 9 can drive the shaft 13 to rotate, and the silicon carbide workpiece can be placed on the carrier plate 15 on the outer wall of the shaft 13. When the shaft 13 rotates, the workpiece can be rotated through the carrier plate 15, which can make the workpiece heat up quickly and improve the sintering efficiency.

When the cylinder 7 descends, the sealing cover 8 closes on the sintering furnace 2. At this time, the second drive motor 9 and the electric heating device 14 can be started, causing the electric heating device 14 to heat and sinter the workpiece. During heating, the second drive motor 9 drives the carrier plate 15 to rotate via the shaft 13, thereby rotating the workpiece as well.

After sintering, the exhaust fan 17 inside the purification filter cartridge 11 can be started to draw air from the sintering furnace 2, ensuring the sintering process continues smoothly. The gas inside furnace 2 is discharged through electromagnetic butterfly valve 10 and purification filter cartridge 11. When the gas passes through the purification filter cartridge 11, the filter plate 20 inside the purification filter cartridge 11 filters the gas through the purification filter cotton 21, which can prevent harmful gases in the furnace from harming the health of workers and the air environment. It is highly environmentally friendly during use. Then, the second drive motor 9 can be lifted by cylinder 7 through connecting horizontal plate 12. The sealing cover 8 can be opened indirectly by the second drive motor 9. After opening the sealing cover 8, it is easy to remove the shaft 13 together. Then, the first drive motor 5 drives the turntable 3 to rotate, which can drive the cylinder 7 to rotate, thereby moving the workpiece to one side, making it convenient to take out the sintered workpiece. It is quite practical.
