[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] The utility model provides Figures 1 to 4 The illustrated embodiment of a limited-position dipping tank for use in the dipping process of aerogel production includes a dipping tank body 1. A partition 16 is welded and fixed within the dipping tank body 1, dividing the interior of the dipping tank body 1 into a dipping area and an installation area. A stirring assembly and a leveling assembly are assembled within the dipping area, while a linkage is assembled within the installation area. The stirring and leveling assemblies are coupled via a linkage.

[0023] The stirring assembly includes a stirring shaft 6, which is arranged in a horizontal direction and has one end rotatably connected to the partition 16 and the other end rotatably connected to the dipping tank body 1. A plurality of stirring blades are welded and fixed on the stirring shaft 6.

[0024] The motor 5 is fixed to the main body 1 of the dipping tank with bolts, and the output shaft of the motor 5 is coaxially fixedly connected with the stirring shaft 6.

[0025] The scraping assembly includes a scraper 11, fixedly connected to a transmission plate 10. The transmission plate 10 is integrally formed of a horizontal plate and a vertical plate. The scraper 11 is fixedly connected to the horizontal plate, to which two stoppers are welded. The two stoppers are symmetrical about the horizontal plate and together with the horizontal plate form a cross plate. A cross-shaped groove with a cross-shaped cross section is chiseled vertically within the partition plate 16. The cross plate matches the cross groove and slides in a limited manner.

[0026] The horizontal plate of the transmission plate 10 passes through the partition 16, and the vertical plate of the transmission plate 10 is connected to the linkage. The linkage includes a turntable 7, an eccentric shaft 8 and a return frame 9. The turntable 7 is coaxially fixedly connected to the stirring shaft 6, and the eccentric shaft 8 is welded and fixed to the turntable 7 and deviates from the axis of the turntable 7. The return frame 9 is fixedly connected to the vertical plate of the transmission plate 10. The eccentric shaft 8 is parallel to the central axis of the turntable 7. At the same time, the eccentric shaft 8 is inserted into the return frame 9 and has both limited sliding cooperation and abutment transmission cooperation with the return frame 9. It is used to push the return frame 9 up and down.

[0027] The opening of the dip tank body 1 is vertically upward, and a cover plate 2 is fixed to the top of the dip tank body 1 with bolts, covering the opening of the dip tank body 1. A sealing ring 3 is assembled between the cover plate 2 and the top of the dip tank body 1, and the sealing ring 3 is fixedly connected to the cover plate 2 for sealing.

[0028] A mounting plate is welded and fixed on the main body 1 of the dipping tank, and a vacuum pump 4 is fixed on the mounting plate with bolts. The output port of the vacuum pump 4 is communicated with the interior of the main body 1 of the dipping tank, so as to generate a vacuum inside the main body 1 of the dipping tank.

[0029] Inside the main body 1 of the immersion tank, a main shaft 12, a secondary shaft 15, and several transmission shafts 14 are horizontally arranged. The main shaft 12, secondary shaft 15, and several transmission shafts 14 are all rotatably connected to the main body 1 of the immersion tank and are parallel to each other. The several transmission shafts 14 are all located above the stirring shaft 6 and below the main shaft 12 and secondary shaft 15. The several transmission shafts 14 are located between the main shaft 12 and secondary shaft 15 and are arranged in a straight line along the horizontal direction.

[0030] The main shaft 12 and secondary shaft 15 wind the same coil 13. Aerogel sol is added to the main body 1 of the dipping tank, and coil 13 is immersed in the sol. The main shaft 12 winds the portion of coil 13 to be dipped, while the secondary shaft 15 winds the already dipped portion. Several drive shafts 14 roll in contact with the portion of coil 13 immersed in the sol, facilitating its movement.

[0031] The scraper 11 is in sliding contact with the glue-impregnated portion of the coil 13 to scrape off excess sol.

[0032] Working principle: When in use, first inject aerogel sol into the stirring area of the dipping tank body 1. When the aerogel sol overflows all the transmission shafts 14, stop injecting. Then roll the coil 13 to be dipped onto the main shaft 12. At the same time, pull the end of the coil 13 into the sol in the direction away from the main shaft 12 and pass it around the bottom of several transmission shafts 14 in turn, and finally fix the end of the coil 13 on the secondary shaft 15. Afterwards, the cover plate 2 is fixed to the top of the dipping tank body 1 by bolts, the sealing ring 3 is squeezed, and the dipping tank body 1 forms a sealed environment. At the same time, start the vacuum pump 4 to form a vacuum environment in the dipping tank body 1.

[0033] After a period of soaking, motor 5 is started. The output shaft of motor 5 rotates stirring shaft 6, which in turn drives stirring blades to stir the sol and prevent it from solidifying. Simultaneously, stirring shaft 6 rotates turntable 7, which in turn drives eccentric shaft 8 to orbit around stirring shaft 6. Eccentric shaft 8 pushes return frame 9 up and down, which in turn drives transmission plate 10 to slide up and down. Transmission plate 10 drives scraper 11 up and down, scraping off excess gel from the soaked coil 13 and smoothing the sol.

[0034] Subshaft 15 can then be rotated, either by an external motor or manually, to rewind the impregnated web 13. Simultaneously, scraper 11 continuously scrapes away excess gel from web 13 and smoothes the sol. While scraping away excess gel, scraper 11 consistently moves downward relative to web 13.

[0035] After the entire coil 13 is dipped in the glue, the vacuum pump 4 and the motor 5 are turned off, and the entire coil 13 is wound onto the secondary shaft 15. Then, the bolts are tightened to remove the cover plate 2 from the top of the dipping tank body 1, and then the coil 13 is removed from the secondary shaft 15.

[0036] The coil 13 can be removed from the secondary shaft 15 by rotating the secondary shaft 15 to release the coil 13. The end of the coil 13 can be fixed to the secondary shaft 15 manually. The coil 13 can be rewound onto the main shaft 12 manually.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
