Technical Field
[0001] The utility model relates to the technical field of carbon / carbon composite material manufacturing, in particular to an asphalt impregnation-carbonization integrated tooling. Background Art
[0002] Asphalt impregnation-normal pressure carbonization is one of the commonly used preparation processes for C / C composite materials. First, the low-density C / C blank is loaded into the impregnation rack and impregnated at 180-270°C in an asphalt pressure impregnation furnace. The impregnated blank is then loaded into a high-temperature resistant rack and loaded into a carbonization furnace for carbonization at 850°C under nitrogen protection.
[0003] The existing asphalt pressure impregnation furnace uses ordinary carbon steel to make the material rack, and the carbonization furnace uses high-temperature resistant stainless steel to make the material rack. After the temperature of the blank drops to room temperature after impregnation, the blank is manually disassembled and assembled into the carbonization furnace material rack.
[0004] The prior art is time-consuming and labor-intensive to disassemble and assemble the asphalt after it is impregnated and cooled to room temperature. It also requires repeated heating in the carbonization furnace, repeated melting of the asphalt, and reverse osmosis migration of the asphalt, resulting in a low carbonization rate. Repeated heating also wastes energy. During asphalt carbonization, the asphalt reversely migrates and flows to the bottom of the furnace. After carbonization, the temperature is cooled to room temperature, and manual cleaning is required. It takes 2 to 3 days to cool down to room temperature, resulting in low production efficiency. There are also safety hazards in working in a limited space. Summary of the invention

[0007] Furthermore, the impregnation-carbonization rack 1 is composed of a chassis, columns, a hanging plate and intermediate reinforcements, and each component is welded by full welding.
[0008] Furthermore, the asphalt recovery device 2 is formed by connecting the chassis and the recovery cylinder wall by full welding.
[0009] Furthermore, the chassis of the asphalt impregnation-carbonization material rack is made of heat-resistant stainless steel with a thickness of 10 to 20 mm, the columns are made of heat-resistant stainless steel with a thickness of 8 to 12 mm, the lifting plate is made of heat-resistant stainless steel with a thickness of 10 to 20 mm, and the middle is reinforced with 3 to 6 mm heat-resistant stainless steel to prevent deformation under high temperature.
[0010] Furthermore, the thickness of the chassis of the asphalt recovery device is 3 to 8 mm, and the thickness of the recovery cylinder wall is 5 to 12 mm.
[0011] Furthermore, the asphalt impregnation-carbonization rack and the asphalt recovery device are processed with holes with a diameter of 12 to 24 mm, and can be quickly connected and disassembled using M10 to 22 bolts.
[0012] Furthermore, the connecting bolts 3 are made of heat-resistant stainless steel.
[0013] Based on the same utility model concept, the utility model also provides an impregnation-carbonization method of an asphalt impregnation-carbonization integrated tool, comprising the following steps:
[0014] S1: During asphalt impregnation, the blank to be impregnated is loaded into the asphalt impregnation-carbonization rack 1 (without using a recovery device), and then loaded into the asphalt impregnation furnace for impregnation, and taken out of the furnace after the impregnation is completed;
[0015] S2: During carbonization, the impregnated asphalt impregnation-carbonization rack 1 and the asphalt recovery device 2 are connected by bolts 3 to form a whole, and then loaded into the carbonization furnace for carbonization;
[0016] S3: After carbonization, the connecting bolts 3 between the asphalt impregnation-carbonization rack 1 and the asphalt recovery device 2 are removed, and the asphalt impregnation-carbonization rack is moved away to facilitate cleaning of the asphalt carbonization residue in the asphalt recovery device.

[0018] The utility model provides an asphalt impregnation-carbonization integrated tooling and use method, which loads the impregnated blank into the carbonization furnace, avoiding the reheating process, reducing the asphalt turning over and migrating problem, improving the carbon increase rate, and avoiding the problem of manual cleaning of the furnace bottom, effectively improving production efficiency. On the basis of the traditional impregnation furnace material rack and the carbonization furnace material rack, the material rack is made of high-temperature resistant materials to achieve an integrated tooling, eliminating the operator's repeated disassembly and assembly of the material rack, while reducing the problem of low carbon increase rate caused by asphalt reverse osmosis migration, and improving production efficiency; at the same time, an asphalt recovery device is designed, and the asphalt remelting reverse osmosis migration during the carbonization heating process flows into the asphalt recovery device, avoiding the asphalt directly flowing into the carbonization furnace cavity, solving the delay cycle of the operator cleaning the furnace cavity and the safety problem of limited space operation.
