[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0032] Reference Figures 1-3This utility model provides an embodiment of an aldehyde-imide latent curing agent material conveying device, comprising a base plate 1, a storage tank 2 fixedly connected to the top left side of the base plate 1, the storage tank 2 being used to store aldehyde-imide latent curing agent material and provide material source for the entire conveying process, a filter assembly being provided on the top middle side of the base plate 1, the filter assembly being able to filter the material output from the storage tank 2, removing impurities present in the material and ensuring the purity of the conveyed material, a transport tank 5 being fixedly connected to the top right side of the base plate 1, the transport tank 5 serving as the final storage container for receiving the filtered material, a pump 6 being fixedly connected to the top edge of the base plate 1, the pump 6 being used to provide power to extract the material from the storage tank 2 and transport it to the transport tank 5 through a pipeline, a stirring assembly being provided inside the storage tank 2, the stirring assembly being able to stir the material in the storage tank 2 to prevent the material from settling and stratifying during storage;

[0033] Reference Figure 2 The mixing assembly includes a housing 9, which is fixedly connected to the top of the storage tank 2. The housing 9 serves to protect the internal structure of the mixing assembly and provides installation space for the impeller 11. The impeller 11 is rotatably connected inside the housing 9. The impeller 11 can rotate under the action of external power or fluid. A rotating shaft 12 is fixedly connected to the bottom of the impeller 11. When the impeller 11 rotates, it can drive the rotating shaft 12 to rotate synchronously. Multiple stirring rods 13 are fixedly connected to the outer wall of the rotating shaft 12. The rotation of the rotating shaft 12 can cause the stirring rods 13 to stir and mix the material in the storage tank 2. A scraping assembly is installed between the multiple stirring rods 13 on the same side. The scraping assembly can scrape off the material adhering to the inner wall of the storage tank 2 by the stirring rods 13 during the stirring process.

[0034] Reference Figure 3 The scraping assembly includes a limiting block 16, which is fixedly connected to the side of the stirring rod 13 away from the rotating shaft 12. The limiting block 16 is used to limit the connecting sleeve 14. The connecting sleeve 14 is fixedly connected to the outer wall of the limiting block 16. The connecting sleeve 14 serves as a connecting component between the scraper 15 and the stirring rod 13, fixing the scraper 15 to the stirring rod 13 so that the scraper 15 moves synchronously with the stirring rod 13. Scrapers 15 are fixedly connected between multiple connecting sleeves 14. During the stirring process, the scraper 15 contacts the inner wall of the storage tank 2 and removes the material attached to the inner wall through mechanical scraping. A spring 17 is installed on the inner wall of the connecting sleeve 14. The spring 17 provides elastic pre-tightening force so that the scraper 15 fits tightly against the inner wall of the storage tank 2. At the same time, it provides buffering when encountering obstacles to prevent damage to the scraper 15 and the inner wall of the storage tank 2.

[0035] Reference Figure 4The filter assembly includes a support frame 3, which is fixedly connected to the top center of the base plate 1. The support frame 3 provides a support structure for the filter box 4, fixing the filter box 4 at a specific height. The filter box 4 is fixedly connected to the top of the support frame 3. The filter box 4 serves as the main shell of the filter assembly, forming a filter chamber inside to provide space for material filtration. A sealing ring 10 is installed inside the filter box 4 to seal the internal space of the filter box 4 and prevent material leakage during filtration. A filter screen 18 is fixedly connected to the middle of the sealing ring 10. The filter screen 18 serves as the core component of filtration, intercepting solid impurities in the material through its fine pore structure. An installation assembly is provided on the outer wall of the filter box 4 for the installation and removal of the filter screen 18 and the sealing ring 10, facilitating the replacement, cleaning, and maintenance of the filter screen 18.

[0036] Reference Figure 5 The mounting assembly includes two housings 19, which are fixedly connected to the outer wall of the filter box 4. The housings 19 provide installation space and protective structure for the pull rod 20 and the reset assembly. The pull rod 20 is slidably connected inside the housing 19. The filter screen 18 and the sealing ring 10 can be locked and unlocked by manually operating the pull rod 20, which facilitates quick replacement of the filter screen 18. A limit plate 21 is fixedly connected to the outer wall of the pull rod 20. The limit plate 21 is used to limit the sliding stroke of the pull rod 20 and prevent the pull rod 20 from detaching from the housing 19. A reset assembly is provided inside the housing 19. The reset assembly provides reset power to the pull rod 20 and automatically pushes it back to the initial position after the pull rod 20 is unlocked.

[0037] Reference Figure 5 The reset assembly includes two guide rods 22, which are fixedly connected inside the housing 19. The guide rods 22 provide guidance for the sliding of the limiting plate 21 and the pull rod 20, ensuring that they slide smoothly along a predetermined path. A second spring 23 is sleeved on the outer wall of the guide rod 22. The second spring 23 generates elastic deformation during the sliding of the limiting plate 21, storing elastic potential energy. When the external force disappears, it releases the elastic potential energy, pushing the limiting plate 21 and the pull rod 20 to reset. The inner wall of the limiting plate 21 is slidably connected to the outer wall of the guide rod 22, and the movement trajectory of the limiting plate 21 is restricted by the guide rod 22.

[0038] Reference Figure 2 The bottom of the storage tank 2 is fixedly connected to the discharge port 7, which serves as a material outflow channel to guide the material in the storage tank 2 into the pipeline 8. A valve is installed on the discharge port 7 to control the outflow status of the material.

[0039] Reference Figure 1A pipe 8 is provided between the input end of the extraction pump 6 and the discharge port 7. A pipe 8 is also installed at the output end of the extraction pump 6. One end of the pipe 8 penetrates the shell 9 and the filter box 4 and is located inside the transport tank 5. Under the action of the pipe 8, the material is first extracted and passes through the inside of the shell 9, thereby driving the impeller 11 to rotate. Then, it is transported to the inside of the filter box 4 to filter impurities, and finally it is transported to the inside of the transport tank 5.

[0040] Reference Figure 4 and Figure 5 The pull rod 20 passes through the filter box 4 and engages with the sealing ring 10. The engaging structure fixes the sealing ring 10 and the filter screen 18 inside the filter box 4, ensuring the airtightness of the filtration process.

[0041] Working principle: When it is necessary to transport aldehyde-imide latent curing agent materials, the extraction pump 6 is started and the valve on the discharge port 7 is opened. After the extraction pump 6 starts, it will extract the aldehyde-imide latent curing agent materials inside the storage tank 2 and transport them to the shell 9 through the pipeline 8. After being transported to the shell 9, the impeller 11 will rotate due to the flow of materials. When the impeller 11 rotates, it will drive the stirring rod 13 to rotate through the rotating shaft 12, stirring the materials in the storage tank 2. At the same time, the scraper 15 is tightly attached to the inner wall of the storage tank 2 under the action of the spring 17, and scrapes off the materials attached to the inner wall as it moves with the stirring rod 13.

[0042] The material is then transported through pipe 8 to the filter box 4 for filtration. When the filter screen 18 needs to be cleaned after long-term use, the two pull rods 20 are pulled to slide the limit plate 21 and compress the spring 23. When the pull rods 20 are disengaged from the sealing ring 10, the sealing ring 10 and the filter screen 18 can be removed for maintenance. After the operation is completed, the pull rods 20 automatically reset under the action of the spring 23 and re-engage with the sealing ring 10 to fix the sealing ring 10. The filtered material continues to be transported through pipe 8 and finally enters the transport tank 5 for storage.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
