Description

Technical Field

[0001] This utility model relates to the field of vacuum impregnation technology, specifically to a vacuum impregnation and exhaust device for composite materials. Background Technology

[0002] Vacuum impregnation is a process technology that uses alternating vacuum and pressure to allow liquid impregnating agents (such as resins, waxes, insulating varnishes, etc.) to deeply penetrate porous materials. The materials processed are generally composite materials composed of different materials. Vacuum impregnation requires specialized equipment. The vacuum impregnation exhaust device is a special device that uses alternating vacuuming and pressurization to achieve the removal of gas inside the material and efficient penetration of the impregnating agent.

[0003] Currently, the impregnation and exhaust device still has some shortcomings, such as poor sealing performance:

[0004] To overcome the problem of poor sealing effect, the prior art (publication number: CN215234251U) Chinese patent discloses a vacuum impregnation device for catalysts, which is connected to a fixing seat through a top cover, and the position of the compressor is fixed through the fixing seat. Compared with the traditional mode, the design is a combined connection, which facilitates the control of the tank during the application process and is convenient to use. A detachable structure is set between the tank and the top cover, and a sealing sleeve is used for sealing connection to improve the sealing performance between the tank and the top cover, thereby ensuring that the pressure inside the tank does not leak out.

[0005] However, the currently used impregnation venting device still has certain shortcomings. The above document improves the sealing performance through the design structure between the tank and the top cover, but the device needs to vent during use. However, the gas in the mixed material is prone to deposit inside the tank, which will affect the venting effect and the quality of impregnation. Therefore, the existing structure needs to be improved. Utility Model Content

[0014] Furthermore, a motor is installed inside the bottom end of the stirring rod, and a threaded rod is fixed to the output end of the motor.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

Detailed Implementation

[0027] 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.

[0028] Example 1, such as Figures 1-4The present invention provides the following technical solution to address the problem that the stirring rod 303 of the impregnation exhaust device is inconvenient to replace, thus affecting its efficiency: a disassembly and assembly mechanism is disclosed, comprising a tank body 1, a tank cover 2 connected to the top of the tank body 1, a drive device 3 installed on the top of the tank cover 2, and an exhaust pump 4 installed on the side of the tank body 1; a connecting block 301 is connected to the output end of the drive device 3, a through groove 302 is provided on the side of the connecting block 301, and the stirring rod 303 is connected to the bottom of the connecting block 301; the stirring rod 303 is close to... The end surface of the near-connecting block 301 is connected with a threaded groove. The bottom of the connecting block 301 is provided with a disassembly and assembly mechanism for replacing the stirring main rod 303. The disassembly and assembly mechanism includes a threaded ring 304, which is threadedly connected to the end surface of the stirring main rod 303. A rotating block 305 is rotatably connected to the side of the stirring main rod 303. The rotating block 305 and the through groove 302 are each provided with three sets. A fixing block 306 is fixed to the top of the stirring main rod 303. The fixing block 306 has three fixing grooves on its side. The fixing grooves and the rotating block 305 form a snap-fit ​​connection.

[0029] Different types of stirring rods 303 in the exhaust impregnation device have different stirring effects. When replacement is needed, first rotate the threaded ring 304 so that it can slide through the threaded groove on the surface of the stirring rod 303. When the threaded ring 304 slides, it can slowly move out of the side of the rotating block 305. Without the squeezing restriction of the threaded ring 304, the rotating block 305 can be rotated. When the rotating block 305 rotates, it can rotate through the stirring rod 303. When the rotating block 305 rotates, it can also rotate out of the fixed block 306 and the through groove 302. When the rotating block 305 rotates out, it pulls down the stirring rod 303. When the stirring rod 303 is pulled down, it can drive the fixed block 306 to slide down inside the connecting block 301. When the fixed block 306 slides out of the connecting block 301, the stirring rod 303 and the connecting block 301 can be separated and disassembled. After the stirring rod 303 is disassembled, different types can be replaced, which improves the ease of use of the exhaust impregnation device.

[0030] Example 2, as follows Figure 2 , Figure 5 and Figure 6The present invention provides the following technical solution to address the problem of low exhaust efficiency and easy gas deposition in the impregnation exhaust device. Based on Embodiment 1, an adjustment mechanism is disclosed: a sliding groove 307 is provided through the side of the stirring main rod 303. An adjustment mechanism for improving the exhaust efficiency of the impregnation exhaust device is provided inside the sliding groove 307. The adjustment mechanism includes a toothed plate 308, which slides inside the sliding groove 307. Multiple sets of toothed plates 308 are slidably connected inside the sliding groove 307, and these multiple sets of toothed plates 308 are respectively fixed to a fixed... Rotating toothed blocks 309 are meshed with the surface and both ends of rod 315 and the two sides of toothed plate 308. Rotating toothed blocks 309 rotate through the sliding groove 307. A stirring support rod 310 is fixed to the side of rotating toothed blocks 309. A limiting groove 311 is opened at the bottom of sliding groove 307. A limiting block 312 slides inside the limiting groove 311. The limiting block 312 is fixed to the bottom end of toothed plate 308. A threaded rod 313 is threadedly connected inside the limiting block 312. A motor 314 is installed inside the bottom end of stirring main rod 303. The output end of motor 314 is fixed with threaded rod 313.

[0031] During operation, the exhaust device requires the drive device 3 to agitate the impregnating material inside the tank body 1, allowing material bubbles and exhaust gases to be discharged more effectively and quickly. The exhaust gas is then extracted and discharged by the exhaust pump 4, improving the quality and effect of the material impregnation. To enhance the agitation, the motor 314 can be started. The output end of the motor 314 drives the threaded rod 313 to rotate. The rotation of the threaded rod 313 causes the limiting block 312 to slide threadedly. The limiting block 312 slides through the limiting groove 311, and this sliding motion causes the toothed plate 308 to move. When the toothed plate 308 moves, it can drive the fixed rod 315 to move. Both the fixed rod 315 and the toothed plate 308 can slide through the sliding groove 307. The fixed rod 315 can drive multiple toothed plates 308 to slide synchronously. When the toothed plate 308 moves, it can also drive the rotating toothed block 309 to mesh and rotate. When the rotating toothed block 309 meshes and rotates, it can drive the stirring support rod 310 to rotate. When the stirring support rod 310 rotates, it can adjust its own angle. When the angle of the stirring support rod 310 is adjusted, it can change the efficiency and effect of stirring the material, thereby further accelerating the efficiency of material bubbles and exhaust gas discharge, and improving the exhaust efficiency of the vacuum impregnation exhaust device.

[0032] Although the present invention 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 invention should be included within the protection scope of the present invention.
