Description

Technical Field

[0001] This invention relates to the field of graphite impregnation technology, specifically to a method and apparatus for impregnating graphite with modified resin. Background Technology

[0002] Graphite, an allotrope of carbon, is renowned for its high electrical conductivity and high-temperature resistance, and is widely used in various fields. Beyond its excellent physicochemical properties, graphite's performance and applications are further enhanced through various processes. From basic science to industrial applications, graphite demonstrates its irreplaceable position in modern technology. Impregnating graphite with synthetic resins such as phenolic resins and epoxy resins can significantly improve its mechanical strength, reduce porosity, and enhance its acid and alkali resistance. Graphite impregnation is a process that improves the performance of graphite by filling its pores with synthetic resins or other materials. Selecting suitable graphite materials and pretreatment, including cleaning, drying, and sieving, is crucial. To ensure the purity and particle size meet requirements, the pretreated graphite material is placed in an impregnation tank, and the selected impregnating agent, such as phenolic resin or epoxy resin, is added. The impregnation time and temperature are carefully controlled to ensure full penetration. After impregnation, the material is dried and heat-cured to allow the resin to form a robust structure in the graphite pores. The curing temperature and pressure must be strictly controlled to achieve the best results. The cured material is then cut, drilled, and surface-treated to meet specific application requirements, such as mechanical seals, bearings, and other high-performance applications. This process not only enhances the strength and wear resistance of the graphite material but also endows it with properties such as water impermeability, improved corrosion resistance, and thermal stability.

[0003] For example, patent document CN 115410779 A discloses a graphite electrode impregnation method and apparatus, belonging to the field of graphite electrode impregnation technology, including the following steps: S1, placing the graphite electrode into an impregnation container and sealing the impregnation container; S2, evacuating the impregnation container to 0.06-0.09 MPa; S3, injecting an antioxidant protective liquid into the impregnation container until the liquid level of the antioxidant protective liquid is higher than the surface of the graphite electrode; S4, maintaining static impregnation for 8-12 minutes; S5, after impregnation is completed, depressurizing the impregnation container to atmospheric pressure; S6, recovering the antioxidant protective liquid, opening the impregnation container, and removing the graphite electrode. This invention involves transferring the graphite electrode into an impregnation container and evacuating it to 0.06–0.09 MPa to remove gas from the tiny pores of the graphite electrode. Then, an antioxidant protective solution is injected into the impregnation container and left to stand for 8–12 minutes. This process ensures that the antioxidant protective solution is fully impregnated into the tiny pores of the graphite electrode, effectively improving the efficiency and quality of the graphite electrode impregnation.

[0004] However, the resin materials used in existing graphite impregnation processes cannot effectively improve the overall heat resistance of graphite materials. During subsequent use, the graphite at the resin-impregnated areas is easily unable to withstand high temperatures, thus limiting the application range of graphite materials in heat-resistant environments. Furthermore, the equipment cannot perform uniform, all-around vacuum pressure impregnation on the graphite columns during the impregnation process, leading to uneven and incomplete impregnation, which in turn affects the overall temperature resistance quality of the graphite. Moreover, the equipment cannot recycle and reuse excess resin material impregnated on the graphite columns during the impregnation process, failing to meet daily usage requirements. Therefore, there is an urgent need to design a method and apparatus for impregnating graphite with modified resin to solve these problems. Summary of the Invention

[0005] The purpose of this invention is to provide a method and apparatus for impregnating graphite with modified resin, in order to solve the problems mentioned in the background art. The resin materials used in the existing graphite impregnation process cannot effectively improve the overall heat resistance of the graphite material. In subsequent use, the graphite material at the resin impregnation site is easily unable to withstand high temperatures, thus limiting the application range of the graphite material in heat-resistant environments. Furthermore, when processing graphite columnar materials, the equipment cannot perform uniform, all-around vacuum pressure impregnation, resulting in uneven and incomplete impregnation within the graphite column after impregnation, which affects the overall temperature resistance quality of the final graphite. Moreover, the equipment cannot recycle and reuse excess resin material impregnated on the graphite column during the graphite impregnation process, failing to meet daily usage requirements.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a method for impregnating graphite with modified resin:

[0007] S1: First, prepare the modified resin and graphite raw materials. The modified resin is used as an impregnating agent to impregnate the graphite, filling it and improving the performance of the impregnated graphite, enabling it to achieve good temperature resistance. This graphite is mainly used to prepare graphite chemical equipment. In daily use, 300° resin (a high-temperature resistant resin - (liquid state, core components: formaldehyde, phenol, and catalyst potassium hydroxide) can be used as a graphite impregnating agent. In this process, 300° resin is used as an impregnating agent. Prepare a resin solution containing additives to ensure that the resin used can fully meet the requirements of graphite impregnation and form a stable structure in the subsequent curing process. Put the treated graphite fibers into the impregnation container, pour in the prepared resin solution, and ensure that the graphite fibers are completely covered. The resin is penetrated into the graphite fibers through vacuum, so that the resin can penetrate evenly and fully into every micropore of the graphite fibers. By filling the pores on the graphite surface and internal pores, heat treatment is then performed to cure the resin, thereby forming a composite material with specific properties.

[0008] S2: 300° resin belongs to the category of synthetic resins. Graphite materials impregnated with 300° resin exhibit excellent heat resistance and can be used in environments ranging from 350°C to 400°C. This is the temperature range in which carbon and graphite begin to oxidize. Graphite itself is one of the non-metallic materials with the best thermal conductivity. After impregnation with 300° resin, its thermal conductivity is preserved, making it suitable for heat transfer equipment, such as graphite reactors, synthesis furnaces, and heat exchangers. The process of impregnating graphite with modified resin is a complex process involving multiple steps and requiring precise operation. By accurately controlling each step, the performance of graphite composite materials can be significantly improved, expanding its application in high-end fields. With the continuous advancement of materials science and process technology, this field is expected to achieve more innovations and breakthroughs in the future.

One end of the storage box is fixedly connected to the filter frame, the top of the storage box is movably connected to the top movable frame, and the bottom of the storage box is movably connected to the bottom movable frame. The bottom of the filter frame is fixedly connected to a connecting seat, and the bottom of the connecting seat is fixedly connected to a recycling box. The end of the recycling box away from the connecting seat is fixedly connected to a support frame, and the inside of the support frame is movably connected to a collection box.

[0014] Preferably, the inner wall of the storage box is provided with an installation frame, one end of which is fixedly connected to an insulated inner liner, and the inner wall of the insulated inner liner is provided with an electric heating rod.

[0015] Preferably, a pressure valve seat is provided at the center of the mounting frame, and a filter tube frame is fixedly connected to the bottom end of the pressure valve seat.

[0016] Preferably, a push airbag is provided at one end of the top adjustment frame and the bottom adjustment frame, a connecting push seat is provided inside the push airbag, and a limit sliding groove is provided inside the top adjustment frame and the bottom adjustment frame.

[0018] Preferably, the bottom of the top movable frame is provided with a first sealing frame, the surface of the impregnation frame is provided with a second sealing frame, a sealing ring is provided between the first sealing frame and the second sealing frame, guide side plates are provided at the upper and lower ends of the inner wall of the layered frame, and an arc-shaped locking plate is provided at the center of the inner wall of the layered frame.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] The method and apparatus for impregnating graphite with modified resin, through the inclusion of an impregnation rack, a layering rack, a layering seat, a first homogenizer rack, a second homogenizer rack, a separator rack, a sealing top rack, a storage tank, a top adjusting rack, a bottom adjusting rack, a top movable rack, a bottom movable rack, a vacuum pump, a ventilation mesh groove, a limiting slider, a pressure valve seat, a pushing airbag, a connecting push seat, a limiting slide groove, a central flow pipe, a diversion side pipe, a connecting side pipe rack, a first sealing frame, a second sealing frame, a sealing ring, a guide side plate, and an arc-shaped retaining plate, enables the equipment to impregnate multiple graphite columns together. The vacuum pressure impregnation production operation is completed evenly and comprehensively. In actual use, the staff first lowers the graphite columns to be impregnated one by one from the top of the impregnation frame. At this time, the graphite columns can be positioned and aligned one by one by the guide side plates and arc-shaped clamping plates designed on both sides of the layered frame inside the impregnation frame. Nine graphite columns are grouped together and positioned and loaded inside the impregnation frame. After loading is completed, the pushing airbags inside the top and bottom adjusting frames can be activated. The top moving part is then moved through the connecting push seat. The limiting sliders of the top and bottom movable frames move along the limiting grooves to achieve a fitting and sealing connection at the upper and lower ends of the impregnation frame. Simultaneously, the vacuum pumps inside the top and bottom movable frames are activated to efficiently vacuum the upper and lower ends of the impregnation frame. This, combined with the sealing rings on the first and second sealing frames, ensures a vacuum seal and tight connection at both ends of the impregnation frame. Afterwards, the resin material inside the storage tank can be injected into the impregnation frame under pressure through the pressure valve seat. The resin material can then be evenly distributed within the impregnation frame via the central flow pipes and branch pipes on the first and second uniforming frames, as well as the connecting side pipes on both sides. Finally, the graphite columns, evenly spaced and positioned within the impregnation frame, are subjected to comprehensive and uniform pressure impregnation at the layering seat of the layering frame. This ensures the resin material fully integrates with the graphite column material, improving the overall heat resistance of the final graphite material and demonstrating the practicality of the equipment design.

[0021] This method and apparatus for impregnating graphite with modified resin, through the inclusion of an impregnation rack, filter rack, connecting seat, recovery box, support rack, collection box, support tank, seepage plate, seepage hole tank, vacuum pump, limit slider, extraction tank, filter extraction rack, filter element, mounting frame, heat-insulating inner liner, heating rod, pressure valve seat, and filter tube rack, further improves the overall performance of the equipment. During daily use, after the graphite column material inside the impregnation rack has been impregnated, the impregnating agent can be extracted from the impregnation rack through the pressure valve seat. At this time, the filter element with its insert design inside the filter tube rack can quickly adsorb and filter the graphite waste mixed in with the impregnating agent, ensuring that the impregnating agent entering the storage box is always in a pure state. The impregnating agent inside the storage box can be filtered through the heat-insulating inner liner and inner wall. The heating rod provides uniform heating to ensure optimal impregnation temperature, improving the impregnation effect on the graphite column material. After the impregnating agent inside the impregnation rack is recovered, the top and bottom movable frames can be retracted into the storage tank. The graphite column material that has been impregnated inside the impregnation rack then falls into the collection box at the support frame. Excess impregnating agent on the graphite column material inside the collection box can seep out through the seepage holes in the seepage plate on the bottom wall of the support tank. Afterwards, the impregnating agent is recycled and reused by passing through the limit slider of the filter frame into the storage box via the recovery box and connecting seat. The filter element inside the filter frame can also adsorb and remove graphite impurities from the recycled impregnating agent, ensuring the subsequent use effect of the impregnating agent and demonstrating the comprehensiveness of the equipment design.

The center of the installation frame 27 is provided with a pressure valve seat 30, and the bottom end of the pressure valve seat 30 is fixedly connected to a filter tube rack 31. One end of the top adjustment frame 9 and the bottom adjustment frame 10 is provided with a push air bag 32, and the inside of the push air bag 32 is provided with a connecting push seat 33. The inside of the top adjustment frame 9 and the bottom adjustment frame 10 is provided with a limit slide groove 34.

A central flow tube 35 is provided, with branch side tubes 36 evenly fixedly connected to both sides of the central flow tube 35. Connecting side tube frames 37 are evenly arranged on both sides of the impregnation frame 1. A first sealing frame 38 is provided at the bottom of the top movable frame 12, and a second sealing frame 39 is provided on the surface of the impregnation frame 1. A sealing ring 40 is provided between the first sealing frame 38 and the second sealing frame 39. Guide side plates 41 are provided at the upper and lower ends of the inner wall of the layered frame 2, and an arc-shaped locking plate 42 is provided at the center of the inner wall of the layered frame 2. The push airbags 32 inside the top adjusting frame 9 and the bottom adjusting frame 10 are activated, and the connection... The pusher 33 moves the limiting sliders 23 of the top movable frame 12 and the bottom movable frame 13 along the limiting groove 34 to adapt to each other, so that the top movable frame 12 and the bottom movable frame 13 can perform an adaptive sealing docking operation at the upper and lower ends of the impregnation frame 1. At this time, the vacuum pump 21 inside the center of the top movable frame 12 and the bottom movable frame 13 is started simultaneously to perform a synchronous and efficient vacuuming operation at the upper and lower ends of the impregnation frame 1. With the help of the sealing rings 40 on the first sealing frame 38 and the second sealing frame 39, the upper and lower ends of the impregnation frame 1 are vacuum sealed and tightly docked.

[0038] The storage box 8 is equipped with a filter frame 11, a top movable frame 12, and a bottom movable frame 13. One end of the storage box 8 is fixedly connected to the filter frame 11, the top of the storage box 8 is movably connected to the top movable frame 12, and the bottom of the storage box 8 is movably connected to the bottom movable frame 13. A connecting seat 14 is fixedly connected to the bottom of the filter frame 11, and a recycling box 15 is fixedly connected to the bottom of the connecting seat 14. A support frame 16 is fixedly connected to the end of the recycling box 15 away from the connecting seat 14. A collection box 17 is movably connected inside the support frame 16. A support groove 18 is provided inside the support frame 16, and a seepage plate 19 is provided on the inner bottom wall of the support groove 18. Seepage holes 20 are evenly distributed on the surface of the seepage plate 19. A vacuum pump 21 is located at the center of the top movable frame 12, and ventilation mesh grooves 22 are provided on the side of the top movable frame 12. A limited... The filter frame 11 has a limit slider 23 at its top and a pull groove 24 at its bottom. A filter drawer 25 is movably connected to the back of the filter frame 11, and a filter core 26 is provided on the front of the filter drawer 25. After the impregnating agent inside the impregnation frame 1 is recovered, the top movable frame 12 and bottom movable frame 13 of the impregnation frame 1 can be retracted into the storage box 8. Then, the graphite column raw material that has been impregnated inside the impregnation frame 1 falls into the collection box 17 at the support frame 16. The excess impregnating agent on the graphite column raw material inside the collection box 17 can seep out from the seepage hole groove 20 of the seepage plate 19 on the bottom wall of the support groove 18. Then, the impregnating agent is recycled and reused by passing through the limit slider 23 of the filter frame 11 into the storage box 8 through the recovery box 15 and the connecting seat 14.

[0039] Working principle: During use, the operator first lowers the graphite columns to be impregnated one by one from the top of the impregnation frame 1. The graphite columns are positioned and aligned as they fall through the guide plates 41 and arc-shaped locking plates 42 designed on both sides of the layered frame 2 inside the impregnation frame 1. Nine graphite columns are grouped together and positioned for loading inside the impregnation frame 1. After loading, the push airbags 32 inside the top adjusting frame 9 and bottom adjusting frame 10 are activated. Through the connecting push base 33, the limiting sliders 23 of the top movable frame 12 and bottom movable frame 13 are moved along the limiting groove 34, allowing the top movable frame 12 and bottom movable frame 13 to achieve a sealing connection at the upper and lower ends of the impregnation frame 1. The vacuum pump 21 inside the top movable frame 12 and the bottom movable frame 13 is started first, and a synchronous and efficient vacuuming operation is performed at the upper and lower ends of the impregnation frame 1. This, combined with the sealing rings 40 on the first sealing frame 38 and the second sealing frame 39, achieves a vacuum sealing and clamping operation at the upper and lower ends of the impregnation frame 1. Afterwards, the resin material inside the storage tank 8 can be injected into the impregnation frame 1 under pressure through the pressure valve seat 30. At this time, the resin material can be evenly distributed inside the impregnation frame 1 through the central flow pipe 35 and the diversion side pipe 36 on the first homogenizer frame 4 and the second homogenizer frame 5, as well as the connecting side pipe frame 37 on both sides of the impregnation frame 1. Finally, the stone is evenly divided and positioned inside the impregnation frame 1 at the layering seat 3 of the layering frame 2. The graphite column undergoes a comprehensive and uniform pressure impregnation process to ensure that the resin material can fully impregnate and fuse with the graphite column raw material, thereby improving the overall heat resistance of the final graphite material. During daily use, after the graphite column material inside the impregnation rack 1 has been impregnated, the impregnating agent can be withdrawn from the impregnation rack 1 through the pressure valve seat 30. At this time, the filter element 26 with its insert design inside the filter tube rack 31 can quickly adsorb and filter the graphite waste mixed in with the impregnating agent, ensuring that the impregnating agent entering the storage tank 8 is always in a pure state. The impregnating agent inside the storage tank 8 can be uniformly heated through the heat-insulated inner liner 28 and the electric heating rod 29 on the inner wall to ensure it is at the optimal impregnation temperature, improving the bonding between the resin material and the graphite column. After the impregnation effect of the raw material is achieved and the impregnating agent inside the impregnation rack 1 is recovered, the top movable rack 12 and bottom movable rack 13 of the impregnation rack 1 can be retracted into the storage box 8. Then, the graphite column raw material that has been impregnated inside the impregnation rack 1 falls into the collection box 17 at the support rack 16. Excess impregnating agent on the graphite column raw material inside the collection box 17 can seep out from the seepage hole groove 20 of the seepage plate 19 on the bottom wall of the support tank 18. Afterwards, the impregnating agent is recycled and reused in the storage box 8 through the limit slider 23 of the filter rack 11 via the recovery box 15 and the connecting seat 14. The filter element 26 inside the filter rack 11 can also adsorb and remove graphite impurities from the recycled impregnating agent, ensuring the subsequent use effect of the impregnating agent.The above describes the entire working principle of this invention.
