Description

[0001] The present invention relates to the technical field of sintering furnaces, and particularly to a high-temperature furnace for the production of silicon carbide composite ceramic materials. Background Art

[0002] Silicon carbide ceramic materials have been increasingly widely used in many fields such as automobiles, mechanical chemical engineering, environmental protection, space technology, information electronics, and energy. In the automotive field, they can be used to manufacture high-performance engine components and brake system components. In the field of mechanical chemical engineering, they can be used as wear-resistant and corrosion-resistant pipeline, valve, and pump body materials. They can also be used in high-temperature waste gas treatment and sewage treatment equipment. The production of silicon carbide composite ceramic materials requires professional equipment support, and the high-temperature furnace for the production of silicon carbide composite ceramic materials plays a crucial role.

[0003] Regarding the currently existing high-temperature furnaces for the production of silicon carbide composite ceramic materials, the sintering rack needs to be manually operated for loading and unloading in the high-temperature state, which poses a risk of scalding, and the manual operation efficiency is low. The sintering rack lacks automatic positioning control during the moving process, which affects the production efficiency and product quality. In addition, after the high-temperature furnace is used multiple times, the inner wall is prone to adhesion of dust and debris, resulting in a decrease in heat conduction efficiency, an increase in energy consumption, and the device lacks an automatic cleaning function, requiring manual cleaning at regular intervals, which increases the maintenance cost and time.

[0015] The present invention provides a high-temperature furnace for producing silicon carbide composite ceramic materials, which has the following beneficial effects: In the present invention, through the linkage design, the automatic positioning control of the sintering rack and the furnace cleaning function are realized; when the sintering rack needs to enter and exit the warehouse, the driving motor drives the driving gear to rotate, and the left and right movement of the sintering rack is realized through meshing with the rack. After moving to the preset position, the meshing mechanism of the outer tooth block and the driving gear cooperates with the first elastic member to ensure the accurate positioning and automatic stop of the sintering rack, avoiding the high-temperature risk of manual operation; at the same time, when the sintering rack is at the blanking station, the linkage gear forms a transmission chain with the driving gear and the output gear, driving the cleaning frame to reciprocate up and down, automatically scraping the dust and debris on the inner wall of the furnace, effectively maintaining the heat conduction efficiency, reducing energy consumption, and having a better energy-saving effect; when the sintering rack is not at the blanking station, the linkage gear is disengaged from the output gear, and the cleaning frame automatically resets under the action of the second elastic member, without affecting the entry and exit of the sintering rack, further improving the linkage, stability and operation efficiency of the device; realizing the automatic operation and efficient cleaning of the sintering station, significantly improving the overall performance and use effect of the equipment.

The first elastic member is compressed until the outer tooth block is no longer meshed with the driving gear. Under the action of the first elastic member, the outer tooth block moves left and resets, that is, the outer tooth block is meshed with the driving gear, so that the outer tooth block reciprocates, so that the sintering rack of the device moves to the preset position and maintains the position unchanged under its own gravity, and the driving gear continues to rotate at this time.

A bracket plate 403 is also fixedly mounted on the traction frame 4, and a linkage gear 4031 is rotatably mounted on the bracket plate 403.

[0033] like Figures 5 to 7As shown in the figure, a driving motor 1021 is fixedly installed at the outer end of the fixed plate 102. A driving gear 1022 is fixedly installed on the transmission shaft of the driving motor 1021, and the driving gear 1022 is in meshing transmission connection with a rack 402 on the traction frame 4. Two groups of guide grooves 101 are fixedly installed at the top of the base 1. Guide blocks 405 are fixedly installed at the bottom of the traction frame 4, and the guide blocks 405 at the bottom of the traction frame 4 are respectively slidably installed on the guide grooves 101 at the top of the base 1. Support rods 4021 are respectively fixedly installed at both ends of the rack 402. A connecting plate 4041 is fixedly installed on the outer tooth block 404. A sliding hole is formed in the connecting plate 4041, and the sliding holes of the connecting plate 4041 on the outer tooth block 404 are respectively slidably installed on the support rods 4021 at both ends of the rack 402. A set of first elastic members 4022 are respectively sleeved on the support rods 4021 at both ends of the rack 402, and the outer ends of the first elastic members 4022 are in contact with the inner end faces of the connecting plates 4041 on the outer tooth block 404; specifically, the electric hatch 202 at the outer end of the sintering furnace 2 can move up and down.

At this time, the top of the linkage gear 4031 is meshed and connected to the output gear 2061, the bottom of the linkage gear 4031 is meshed and connected to the top of the driving gear 1022, and the driving gear 1 022 rotates to drive the output gear 2061 to rotate through the linkage gear 4031, and the first sprocket 2032 on the rotating shaft 203 is connected with the second sprocket 2062 on the linkage shaft 206 through the chain 204 to drive the rotating shaft 203 to rotate, and the connecting rod 501 at the bottom of the cleaning frame 5 is slidably installed on the sliding hole of the connecting seat 201 at the top of the sintering furnace 2, and the connecting shaft body 2031 at the outer end of the rotating shaft 203 is slidably installed on the traction groove 503 at the outer end of the cleaning frame 5 to drive the scraper 5021 on the cleaning frame 5 to reciprocate up and down, so as to automatically scrape off the dust and debris adhered to the heating end of the inner wall of the sintering furnace 2, so as to avoid the sintering furnace 2 of the device after repeated use. The dust and debris adhered to the inner wall of the device causes a decrease in thermal conductivity and an increase in power consumption, so that the device has better cleaning and energy-saving effects, and effectively improves the overall performance of the device.

The first elastic member 4022 causes the driving gear 1022 to continue to rotate, the outer tooth block 404 moves to the right, and the first elastic member 4022 is compressed until the outer tooth block 404 is not meshed with the driving gear 1022. Under the action of the first elastic member 4022, the outer tooth block 404 moves leftward and resets, that is, the outer tooth block 404 is meshed with the driving gear 1022, and then the outer tooth block 404 reciprocates, so that the sintering rack 3 of the device moves to the preset position and keeps the position unchanged under its own gravity, and at this time the driving gear 1022 continues to rotate. Similarly, the driving gear 1022 rotates clockwise to drive the sintering rack 3 to move outward, so that the device is convenient for pulling and moving the sintering rack 3, and the sintering rack 3 moves to the preset position. After the sintering rack 3 is in the set position, it can stop automatically, realizing the automatic positioning control of the sintering station, significantly improving the automation level of the equipment operation, and making the device have a better use effect; when the sintering rack 3 is moved outward to the unloading station, at this time, the driving gear 1022 continues to rotate, and the position of the sintering rack 3 remains unchanged.
