Abstract
Description
Technical Field
[0001] This utility model relates to the field of carbon-carbon composite material preparation technology, specifically to an apparatus for preparing carbon-carbon composite materials. Background Technology
[0002] Carbon-carbon composite materials are mainly prepared by chemical vapor deposition and liquid phase impregnation-carbonization. Chemical vapor deposition involves depositing carbon into the pores of the preform to increase density, but it is time-consuming and difficult for thick products. Liquid phase impregnation-carbonization involves immersing the carbon fiber preform in a liquid impregnating agent and then cycling through pressure, curing, and carbonization to achieve the required density. It has simple equipment and wide applicability.
[0003] However, existing technologies still have the following problems:
[0004] Existing equipment for preparing carbon-carbon composite materials mostly uses a simple stirring method, typically employing only a simple mechanical stirring paddle. The shape and structure of the stirring paddle are relatively simple, failing to generate a complex flow field. This results in insufficient flow of the impregnating agent within the tank, easily leading to localized uneven mixing. Consequently, the stirring efficiency is low, requiring a longer time to fully mix the impregnating agent with the carbon fiber preform, thus prolonging the preparation cycle and reducing production efficiency.
[0005] To address the aforementioned problems, the inventors have proposed an apparatus for preparing carbon-carbon composite materials. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Example 1: As Figure 1-2 As shown, this utility model provides an apparatus for preparing carbon-carbon composite materials, including a tank body 1, an impregnating agent storage tank 2 on one side of the tank body 1, a delivery pump 21 fixedly mounted on the upper end of the impregnating agent storage tank 2, a delivery pipe 22 fixedly mounted on one end of the delivery pump 21, and one end of the delivery pipe 22 connected to the tank body 1, two placement racks 45 inside the tank body 1, a motor 3 on one side of the lower end of the tank body 1, a drive gear 31 fixedly mounted on the output end of the motor 3, a gear ring 32 meshing with the outer surface of the drive gear 31, a support member 33 fixedly mounted on the inner surface of the gear ring 32, a connecting column 34 fixedly mounted on the upper end of the support member 33, the upper end of the connecting column 34 penetrating the tank body 1 and fixedly mounted on a rotating shaft 35, and the outer surface of the rotating shaft 35 fixedly mounted on the... An inner spiral blade 36 is fixedly provided, and an outer spiral blade 37 is fixedly provided on the outer surface of the inner spiral blade 36. The impregnating agent in the impregnating agent storage tank 2 is transported to the tank body 1 through the delivery pipe 22 under the action of the delivery pump 21. The carbon fiber preform is placed on the placement rack 45. After the motor 3 is started, it drives the drive gear 31 at the output end to rotate. The drive gear 31 meshes with the gear ring 32, thereby causing the gear ring 32 to rotate. The support member 33, connecting column 34, and rotating shaft 35 on the inner surface of the gear ring 32 rotate together. The inner spiral blade 36 and the outer spiral blade 37 on the rotating shaft 35 begin to rotate. During the rotation, the inner spiral blade 36 and the outer spiral blade 37 drive the liquid in the tank body 1 to flow, thereby realizing the stirring and mixing of the impregnating agent and the carbon fiber preform.
[0018] Support rods 38 are fixedly installed on both inner walls of the tank body 1, and the upper end of the rotating shaft 35 is rotatably connected to the support rods 38. A lower rotating rod 39 is fixedly sleeved on the lower outer surface of the rotating shaft 35, and lower stirring columns 310 are fixedly installed on both sides of the upper end of the lower rotating rod 39. A liquid outlet pipe 11 is provided on one side of the lower end of the tank body 1. The support rods 38 provide rotational support for the upper end of the rotating shaft 35. When the rotating shaft 35 rotates, the lower rotating rod 39 and the lower stirring column 310 rotate simultaneously, further enhancing the stirring effect and allowing the impregnating agent to come into full contact with the preform. The liquid outlet pipe 11 can discharge the impregnating agent. The combination design of the inner spiral blade 36 and the outer spiral blade 37, as well as the auxiliary stirring of the lower rotating rod 39 and the lower stirring column 310, can generate a complex flow field, allowing the impregnating agent to flow fully in the tank body 1, improving stirring efficiency and mixing uniformity. The motor 3 drives the rotating shaft 35 to rotate through the drive gear 31 and the gear ring 32. The transmission is stable and reliable, and can provide sufficient stirring power.
[0019] Example 2: Figure 1-3 As shown, two uprights 4 are fixedly installed at the upper end of the tank body 1, and an upper plate 41 is fixedly installed at the upper end of the two uprights 4. A telescopic air rod 42 is fixedly installed at the lower end of the upper plate 41, and a lifting plate 43 is fixedly installed at the output end of the telescopic air rod 42. Support columns 44 are fixedly installed on both sides of the lower end of the lifting plate 43, and the lower ends of the support columns 44 are fixedly connected to the placement frame 45. Through slots 46 for use with the placement frame 45 are opened on both sides of the upper end of the tank body 1, and sealing plates 47 for use with the through slots 46 are fixedly installed on both sides of the lifting plate 43. Two limiting posts 48 are fixedly installed at the lower end of the upper plate 41, and the outer surface of the limiting posts 48 is movably connected to the lifting plate 43. When it is necessary to place or remove the carbon fiber preform, the telescopic air rod 42 on the upper plate 41 is activated. The output end of the telescopic air rod 42 pushes the lifting plate 43 down. The lifting plate 43 is connected to the placement frame 45 through the support column 44, thereby driving the placement frame 45 down. The placement frame 45 enters the interior of the tank 1 through the through groove 46 at the upper end of the tank 1. The sealing plates 47 on both sides of the lifting plate 43 cooperate with the through groove 46 during the lifting process to play a sealing role and prevent the impregnating agent from leaking. After the preform is placed on the placement frame 45, the placement frame 45 is lowered to a suitable position for impregnation. After impregnation is completed, the telescopic air rod 42 retracts, driving the placement frame 45 up to return to the initial position. The placement frame 45 can be raised and lowered by the telescopic air rod 42, which facilitates the placement and removal of the carbon fiber preform. The operation is simple and quick, reducing the difficulty and labor intensity of manual operation.
[0020] Working principle: The impregnating agent in the impregnating agent storage tank 2 is transported to the tank body 1 through the delivery pipe 22 by the delivery pump 21. The carbon fiber preform is placed on the placement rack 45. After the motor 3 is started, it drives the drive gear 31 at the output end to rotate. The drive gear 31 meshes with the gear ring 32, thereby causing the gear ring 32 to rotate. The support 33, connecting column 34 and rotating shaft 35 on the inner surface of the gear ring 32 rotate together. The inner spiral blade 36 and outer spiral blade 37 on the rotating shaft 35 start to rotate. During the rotation, the inner spiral blade 36 and outer spiral blade 37 drive the liquid in the tank body 1 to flow, thereby realizing the stirring and mixing of the impregnating agent and the carbon fiber preform.
[0021] The support rod 38 provides rotational support for the upper end of the rotating shaft 35. When the rotating shaft 35 rotates, the lower rotating rod 39 and the lower stirring column 310 rotate simultaneously, further enhancing the stirring effect and allowing the impregnating agent to come into fuller contact with the preform. The liquid outlet pipe 11 can discharge the impregnating agent. The combination design of the inner spiral blade 36 and the outer spiral blade 37, as well as the auxiliary stirring of the lower rotating rod 39 and the lower stirring column 310, can generate a complex flow field, allowing the impregnating agent to flow fully in the tank 1, improving the stirring efficiency and mixing uniformity. The motor 3 drives the rotating shaft 35 to rotate through the drive gear 31 and the gear ring 32. The transmission is stable and reliable, and can provide sufficient stirring power.
[0022] When it is necessary to place or remove the carbon fiber preform, the telescopic air rod 42 on the upper plate 41 is activated. The output end of the telescopic air rod 42 pushes the lifting plate 43 down. The lifting plate 43 is connected to the placement frame 45 through the support column 44, thereby driving the placement frame 45 down. The placement frame 45 enters the interior of the tank 1 through the through groove 46 at the upper end of the tank 1. The sealing plates 47 on both sides of the lifting plate 43 cooperate with the through groove 46 during the lifting process to play a sealing role and prevent the impregnating agent from leaking. After the preform is placed on the placement frame 45, the placement frame 45 is lowered to the appropriate position for impregnation. After impregnation is completed, the telescopic air rod 42 retracts, driving the placement frame 45 up to return to the initial position. The placement frame 45 can be raised and lowered by the telescopic air rod 42, which facilitates the placement and removal of the carbon fiber preform. The operation is simple and quick, reducing the difficulty and labor intensity of manual operation.
