Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of impregnation carbonization process devices, and particularly relates to a tar adsorption tooling for impregnation carbonization equipment. Background Art
[0002] The impregnation carbonization process refers to a process method for densifying composite materials, in which a preform reinforcement such as a carbon fiber multi-directional woven fabric is impregnated with pitch and then carbonized, causing the pitch to undergo pyrolysis and polycondensation reactions, excluding non-carbon atoms such as hydrogen, nitrogen, and oxygen, and leaving pure carbon.
[0003] In related technologies, after the product undergoes the pitch impregnation and curing process, a large amount of pitch residue remains on the surface. During carbonization, a large amount of tar is generated from these residues and the pitch inside the product. The volatilized tar will adhere to the inner wall and bottom of the equipment, making it difficult to clean the equipment every time it is taken out of the furnace during carbonization. Even the tar will solidify on the loading table and requires a long time to clean and remove, which is time-consuming and laborious. Summary of the Utility Model

[0006] Beneficial effects: By setting a matching inner mold and outer mold, and an adsorption layer sandwiched between the inner mold and the outer mold, the purpose of adsorbing the volatilized tar in all directions during product carbonization is achieved, preventing the tar from contaminating the tooling and carbonization equipment. Most of the volatilized tar is adsorbed and sealed at the aluminosilicate cotton layer, greatly reducing the damage to the carbonization equipment and significantly reducing the volatilization of tar pollutants, protecting the carbonization equipment, ensuring the smooth progress of the processing process. At the same time, the adsorption layer is not directly wrapped outside the product, but is isolated from the product by means of the perforated inner mold, preventing the adsorption layer from adhering to the product and being difficult to handle after adsorbing tar substances, and avoiding contamination and damage to the product, with strong practicability.
[0007] In an alternative embodiment, a plurality of the through holes are uniformly spaced apart and disposed at the wall of the inner mold.

[0026] The following Figure 1 is combined to describe the embodiments of the present utility model.
[0027] According to an embodiment of the present utility model, there is provided a tar adsorption tooling for an impregnation carbonization device, including: an inner mold 1 having an inner housing 11 and an inner cover 12, the inner cover 12 being abutted against an open end of the inner housing 11; a product being disposed inside the inner mold 1; an outer mold 2 having an outer housing 21 and an outer cover 22, the outer cover 22 being detachably connected to an open end of the outer housing 21; the inner mold 1 being located inside the outer mold 2, with a gap between an outer wall of the inner mold 1 and an inner wall of the outer mold 2; an adsorption layer 3 being filled and disposed between the inner mold 1 and the outer mold 2 and wrapping the inner mold 1; the outer mold 2 being adapted to squeeze the inner mold 1 by means of the adsorption layer 3; a through hole 4 being opened in a wall body of the inner mold 1; wherein, the adsorption layer 3 is adapted to adsorb tar emitted outward from the through hole 4 in all directions.
[0028] In this embodiment, the tar adsorption tooling is composed of four parts, namely the inner housing 11, the inner cover 12, the outer housing 21 and the outer cover 22. A plurality of through holes 4 are opened at the four components for gas circulation. The diameter of the through hole 4 can be 10 mm, and the distance between adjacent through holes 4 can be 10 mm. Among them, the size of the inner cavity of the inner mold 1 can be 300 mm in length, 300 mm in width and 150 mm in height, the distance between the inner mold 1 and the outer mold 2 can be 10 mm, and the thickness of the tooling components is 10 mm. The inner housing 11 and the inner cover 12 are aligned with each other and do not have connection structures such as slots and buckles, and are connected by abutting under the extrusion action of the outer mold 2. The connection mode of the outer housing 21 and the outer cover 22 is a detachable connection, specifically a threaded connection, and the fastener 5 is a screw. A screw hole with a diameter of 6 mm is opened at the open end of the outer housing 21, and a screw hole with a diameter of 6 mm is also opened at the corresponding position of the outer cover 22. After the outer housing 21 and the outer cover 22 are aligned, the threaded holes are aligned, and they are connected by means of screws to achieve a fixing effect.
[0029] The specific usage process of the tar adsorption tooling is as follows. An adsorption layer 3 is laid inside the outer housing 21. The material of the adsorption layer 3 can be, but is not limited to, aluminosilicate cotton, and the thickness can be 10 mm. The aluminosilicate cotton layer completely covers and spreads over the inner wall of the outer housing 21. Then, the inner housing 11 is placed into the outer housing 21, and the inner housing 11 is pressed against the adsorption layer 3. The product is placed into the inner housing 11, and the inner cover 12 is taken to cover the open end of the inner housing 11, and the edge of the inner cover 12 is flush with the outer wall surface of the inner housing 11. The inner mold 1 is regularly arranged inside the outer housing 21. Another layer of aluminosilicate cotton is laid above the inner cover 12 to obtain an interlayer 31, and the aluminosilicate cotton layer entirely wraps the outside of the inner mold 1. The outer cover 22 is taken to cover the open end of the outer housing 21, and the outer cover 22 is fixed by means of fasteners 5. After the outer cover 22 is fixed, the outer cover 22 presses against the interlayer 31, and the interlayer 31 transmits the pressing force to the inner cover 12, so that the inner cover 12 is tightly pressed against the inner housing 11 to prevent the inner cover 12 from slipping off. Among them, the aluminosilicate cotton layer is filled between the inner mold 1 and the outer mold 2, so that the outer housing 21 presses against the aluminosilicate cotton layer, and the aluminosilicate cotton layer transmits the pressing force to the inner housing 11, so that the inner housing 11 is tightly pressed to prevent the inner mold 1 from shaking. After the adsorption tooling is encapsulated, the entire adsorption tooling is placed into the furnace. The structure of the adsorption tooling is regular, which is convenient for the furnace loading operation. The product is carbonized in the furnace to generate tar, and the tar volatilizes and disperses outward through the through holes 4. The adsorption layer 3 wrapped around the outside of the inner mold 1 can adsorb most of the volatilized tar substances in all directions and seal them inside the adsorption layer 3, preventing the pollution of the tooling and equipment and preventing it from adhering to the tooling or equipment and being difficult to handle. At the same time, the adsorption layer 3 is not directly wrapped around the outside of the product, but is isolated from the product by means of the perforated inner mold 1, preventing the adsorption layer 3 from adhering to the product and being difficult to handle after adsorbing tar substances and avoiding the pollution and damage of the product. After the process is completed, the fasteners 5 used to encapsulate the outer mold 2 are removed, the outer cover 22, the interlayer 31 and the inner cover 12 are opened in sequence, the product is taken out of the inner housing 11, the used aluminosilicate cotton layer is taken out and treated as solid waste, and the tar pollutants are thereby treated. The adsorption layer 3 is replaceable, and a new aluminosilicate cotton layer is used for the next furnace loading.
[0030] In this embodiment, by providing the mutually cooperating inner mold 1 and outer mold 2, and the adsorption layer 3 sandwiched between the inner mold 1 and the outer mold 2, the purpose of adsorbing the volatilized tar in all directions during the carbonization of the product is achieved, preventing the tar from polluting the tooling and the carbonization equipment. Most of the volatilized tar is adsorbed and sealed at the aluminosilicate cotton layer, greatly reducing the damage to the carbonization equipment and significantly reducing the volatilization of tar pollutants, protecting the carbonization equipment and ensuring the smooth progress of the processing. At the same time, the adsorption layer 3 is not directly wrapped around the outside of the product, but is isolated from the product by means of the perforated inner mold 1, preventing the adsorption layer 3 from adhering to the product and being difficult to handle after adsorbing tar substances and avoiding the pollution and damage of the product. It has strong practicability.
[0031] In some embodiments, in combination with Figure 1 As shown, a plurality of the through holes 4 are respectively and evenly spaced on the inner housing 11 and the inner cover 12. The diameter of the through hole 4 can be 10 mm, and the distance between adjacent through holes 4 can be 10 mm. The adsorption layer 3 is wrapped around the outside of the inner mold 1. The through holes 4 are densely arranged on the wall of the inner mold 1, so that the tar scatters from all directions, preventing the adsorption layer 3 at a single position from losing the adsorption effect due to excessive adsorption of tar, and improving the overall adsorption effect of the tooling, with strong practicability.
[0032] In some embodiments, in combination with Figure 1 As shown, the tooling further includes a fastener 5 provided on the outer mold 2. The outer cover 22 and the outer housing 21 are detachably connected by means of the fastener 5; an external thread is provided on the periphery of the fastener 5, and the fastener 5 can be a screw; connection holes are respectively provided on the outer cover 22 and the outer housing 21, and an external thread is provided on the inner wall of the connection hole; when the outer cover 22 covers the open end of the outer housing 21, the connection holes are aligned; the fastener 5 is screwed into the connection hole, and the external thread cooperates with the internal thread to detachably connect the outer cover 22 and the outer housing 21. After the process is completed, the screw can be unscrewed and removed, which is convenient to operate and has a good fixing effect.
[0033] In some embodiments, in combination with Figure 1 As shown, the outer cover 22 is located relatively above the inner cover 12. The adsorption layer 3 sandwiched between the outer cover 22 and the inner cover 12 is defined as the sandwich layer 31. The outer cover 22 directly presses the inner cover 12 through the sandwich layer 31 to improve the abutting effect between the inner cover 12 and the inner housing 11, prevent the inner cover 12 from slipping, and improve the use effect.
[0034] In some embodiments, in combination with Figure 1 As shown, the two side edges of the inner cover 12 along the first direction are respectively aligned with the two outer side walls of the inner housing 11, so that the adsorption layer 3 is tightly enclosed on the outer wall of the inner mold 1. The outer wall surface of the inner mold 1 is continuously arranged as a whole and does not have raised edges, preventing a large gap from being formed between the adsorption layer 3 and the inner mold 1 when the adsorption layer 3 is wrapped around the outside of the inner mold 1. The adsorption layer 3 and the inner mold 1 are smoothly attached to each other. After the tar volatilizes and escapes through the through holes 4, it is directly adsorbed by the adsorption layer 3, preventing the tar from adhering to tooling components such as the inner mold 1 and improving the use effect.
[0035] In some embodiments, in combination with Figure 1 As shown, the through holes 4 are also opened on the wall of the outer mold 2 to ensure gas circulation.
[0036] In some embodiments, in combination with Figure 1As shown, a plurality of the fasteners 5 are provided at the outer mold 2 to improve the fixing effect between the outer cover 22 and the outer shell 21.
