Description

Technical Field

[0001] This utility model relates to the field of aerogel product manufacturing technology, and in particular to a vacuum impregnation molding device for aerogel products. Background Technology

[0002] Aerogel is a novel lightweight material with a nanoporous structure. It has extremely low density, extremely high specific surface area and excellent thermal insulation properties. It has broad application prospects in aerospace, energy, construction and other fields. The molding of aerogel products usually requires immersing the substrate in an aerogel precursor solution.

[0003] Existing dip molding equipment typically places the substrate to be dipped in a dip tank, and then immerses the tank in a solution. When adding or removing the substrate, the opening and closing of the tank lid must be manually controlled, which is inconvenient. Utility Model Content

[0004] The purpose of this invention is to address the following shortcomings in the existing technology: existing impregnation molding devices typically place the substrate to be impregnated in an impregnation tank and then immerse the tank in a solution. When adding or removing the substrate, manual control of the opening and closing of the tank lid is required, which is inconvenient. Therefore, this invention proposes a vacuum impregnation molding device for aerogel products.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A vacuum impregnation molding apparatus for aerogel products includes a body, an impregnation tank on the upper surface of the body, a V-shaped groove on the tank wall, an impregnation chamber inside the body, a plurality of through holes smaller than the substrate size on the surface of the impregnation chamber, T-shaped sliding grooves symmetrically and horizontally formed on the upper surface of the impregnation chamber, two chamber covers symmetrically arranged on the upper surface of the impregnation chamber, T-shaped sliders symmetrically fixedly installed at the bottom of the chamber covers, and a plurality of sliders slidably arranged in the two sliding grooves respectively. An inlet pipe and an outlet pipe are fixedly installed on both sides of the body, and electric valves are provided in both the inlet pipe and the outlet pipe. An organic cover is rotatably installed on the upper surface of the body, and a vacuum pump connected to the impregnation tank is provided on one side of the body.

[0007] The lid surface is fixedly equipped with sliding rods, and the two sliding rods are symmetrically slidably arranged in the V-groove. The surface of the machine body is provided with a lifting assembly for controlling the vertical movement of the immersion tank.

[0008] Preferably, the lifting assembly includes an electric telescopic rod, a mounting plate is fixedly installed on the surface of the machine body, the electric telescopic rod is vertically fixedly installed on the upper surface of the mounting plate, and the drive shaft of the electric telescopic rod is fixedly connected to the immersion tank through a Z-shaped plate.

[0009] Preferably, the impregnation tank has a circular opening on one side, and a turntable is rotatably installed inside the circular opening. The turntable is located inside the impregnation tank and has multiple stirring rods fixedly installed in a circumferential shape. The rotation of the turntable is controlled by a transmission assembly.

[0010] Preferably, the transmission assembly includes a drive motor, a telescopic cylinder fixedly mounted on the output shaft end of the drive motor, and a stop plate fixedly mounted on the drive shaft end of the telescopic cylinder. The drive motor is fixedly mounted on one side of the machine body through a mounting component. A rotation port is provided on the side wall of the machine body. A sealed bearing is fixedly sleeved on the drive shaft of the telescopic cylinder, and the outer ring wall of the sealed bearing is fixedly connected to the wall of the rotation port.

[0011] Preferably, the mounting component includes a mounting cover, the drive motor is fixedly mounted inside the mounting cover, and the mounting cover is fixedly connected to the side wall of the machine body.

[0012] Preferably, the surfaces of the abutment and the turntable that are close to each other are both bonded with an anti-slip layer, and the anti-slip layer is made of rubber.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The V-shaped groove on the wall of the impregnation tank cooperates with the sliding rod on the surface of the lid. When the impregnation tank moves vertically by the lifting component, the sliding rod slides along the V-shaped groove, which can drive the two lids to slide relative to each other or back to back in the groove through the slider, realizing the automatic opening and closing of the lids without manual operation. This greatly improves the convenience of operation when putting in and taking out the substrate and saves labor costs.

[0015] The impregnation chamber is equipped with a turntable and multiple stirring rods. Driven by the transmission component, the turntable drives the stirring rods to rotate, which can stir the substrate and solution in the impregnation chamber, promote the flow of the aerogel precursor solution around the substrate, and make the solution penetrate into the pores of the substrate more evenly, improve the uniformity and sufficiency of impregnation, and thus improve the molding quality of aerogel products.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0025] Reference Figures 1-2 A vacuum impregnation molding apparatus for aerogel products includes a body 1, an impregnation tank 2 formed on the upper surface of the body 1, and V-shaped grooves 3 formed on the walls of the impregnation tank 2, such as... Figure 4-6 As shown, the machine body 1 is equipped with an impregnation tank 4. The surface of the impregnation tank 4 has multiple through holes 5 with a size smaller than that of the substrate. The upper surface of the impregnation tank 4 has symmetrically horizontally T-shaped grooves 6. The upper surface of the impregnation tank 4 is symmetrically equipped with two tank covers 7. The bottom of the tank cover 7 is symmetrically fixed with T-shaped sliders 8. Multiple sliders 8 are slidably arranged in the two grooves 6. The machine body 1 is fixedly equipped with an inlet pipe and an outlet pipe on both sides. Both the inlet pipe and the outlet pipe are equipped with electric valves. The upper surface of the machine body 1 is rotatably equipped with a cover 19. A vacuum pump 20 connected to the impregnation tank 2 is provided on one side of the machine body 1.

[0026] A sliding rod 9 is fixedly installed on the surface of the box cover 7. The two sliding rods 9 are symmetrically slidably arranged in the V-shaped groove 3. The surface of the machine body 1 is provided with a lifting assembly for controlling the vertical movement of the immersion box 4. The lifting assembly includes an electric telescopic rod 10. A mounting plate is fixedly installed on the surface of the machine body 1. The electric telescopic rod 10 is vertically fixedly installed on the upper surface of the mounting plate, and the drive shaft of the electric telescopic rod 10 is fixedly connected to the immersion box 4 through a Z-shaped plate 11.

[0027] When it is necessary to place the substrate into the impregnation tank 4, the operator first controls the drive shaft of the electric telescopic rod 10 to retract, which drives the Z-shaped plate 11 and the impregnation tank 4 to move upward. During the upward movement of the impregnation tank 4, the slide rod 9 on the tank cover 7 slides upward along the V-shaped groove 3. Since the groove wall of the V-shaped groove 3 is inclined, the slide rod 9 is guided by the groove wall of the V-shaped groove 3, which drives the two tank covers 7 to slide back and forth in the sliding groove 6 through the bottom slider 8, so that the top opening of the impregnation tank 4 gradually opens. When the drive shaft of the electric telescopic rod 10 retracts to the shortest state, the impregnation tank 4 rises to the highest position. At this time, the slide rod 9 slides to the top of the V-shaped groove 3, and the two tank covers 7 are fully opened. The operator can then put the substrate to be impregnated into the impregnation tank 4.

[0028] After the substrate is placed, the drive shaft of the electric telescopic rod 10 extends, driving the impregnation tank 4 to move downward. During this process, the slide rod 9 slides downward along the V-groove 3. Under the guidance of the wall of the V-groove 3, the two tank covers 7 slide relative to each other in the slide groove 6 through the slider 8, gradually approaching and finally joining together to close the top opening of the impregnation tank 4.

[0029] Subsequently, an appropriate amount of aerogel precursor solution is added to the impregnation tank 2 through the electric valve on the inlet pipe. The cover 19 is closed, and the vacuum pump 20 is started. When the vacuum pump 20 is working, it quickly extracts the air from the impregnation tank 2, creating a vacuum environment inside the impregnation tank 2. Under vacuum conditions, the air originally present inside the substrate will expand and escape due to the decrease in external pressure, thus creating a negative pressure inside the substrate. This creates favorable conditions for the penetration of the aerogel precursor solution, effectively avoiding the problem of insufficient wetting of the solution due to air blockage inside the substrate, and significantly improving the penetration efficiency. To ensure thorough impregnation, once the set vacuum level is reached in the impregnation tank 2, the vacuum pump 20 maintains stable operation to preserve the vacuum environment. Then, the drive shaft of the electric telescopic rod 10 is extended to completely immerse the impregnation tank 4 in the solution within the impregnation tank 2. At this point, aided by the vacuum environment, the aerogel precursor solution enters the impregnation tank 4 more rapidly and evenly through the through-hole 5 and quickly penetrates along the pores of the substrate, achieving deep impregnation of the substrate. This fully demonstrates the advantages of vacuum impregnation molding in improving the bonding strength and distribution uniformity between the aerogel and the substrate.

[0030] After impregnation is completed, first turn off the vacuum pump 20, slowly restore the air pressure in the impregnation tank 2, then control the drive shaft of the electric telescopic rod 10 to retract, remove the impregnation tank 4 from the solution, open the electric valve on the outlet pipe to discharge the solution, and finally control the electric telescopic rod 10 again to raise the impregnation tank 4 to the highest position, so that the tank cover 7 opens automatically and the impregnated substrate can be taken out.

[0031] Reference Figure 3 The impregnation tank 4 has a circular opening on one side, and a turntable 12 is rotatably installed inside the circular opening. On the side of the turntable 12 located inside the impregnation tank 4, multiple stirring rods 13 are fixedly installed in a circumferential shape. The turntable 12 is controlled to rotate by a transmission assembly, which includes a drive motor 14, a telescopic cylinder 15 fixedly installed at the end of the output shaft of the drive motor 14, and a stop plate 16 fixedly installed at the end of the drive shaft of the telescopic cylinder 15. The drive motor 14 is fixedly installed on one side of the machine body 1 by a mounting component. A rotation port is opened on the side wall of the machine body 1. A sealed bearing 17 is fixedly sleeved on the drive shaft of the telescopic cylinder 15. The outer ring wall of the sealed bearing 17 is fixedly connected to the wall of the rotation port. The mounting component includes a mounting cover 18. The drive motor 14 is fixedly installed inside the mounting cover 18, and the mounting cover 18 is fixedly connected to the side wall of the machine body 1.

[0032] When the impregnation tank 4 is lowered into the impregnation tank 2 and impregnation molding begins, the turntable 12 on the side wall of the impregnation tank 4 will correspond to the position of the abutment plate 16. The drive motor 14 and the telescopic cylinder 15 are started, causing the drive shaft of the telescopic cylinder 15 to extend and drive the abutment plate 16 to make close contact with the turntable 12. The output shaft of the drive motor 14 rotates, driving the turntable 12 to rotate through the telescopic cylinder 15 and the abutment plate 16. The multiple stirring rods 13 on the turntable 12 rotate in the impregnation tank 4, which agitates the solution and substrate in the impregnation tank 4, further promoting the flow of the aerogel precursor solution around the substrate, making the solution more evenly wrap the substrate and penetrate into each pore, achieving deep impregnation of the substrate. This fully demonstrates the advantages of vacuum impregnation molding in improving the bonding strength and distribution uniformity of aerogel and substrate. After impregnation is completed, the drive motor 14 is turned off, the drive shaft of the telescopic cylinder 15 retracts, and the abutment plate 16 is separated from the turntable 12.

[0033] Both the side of the back plate 16 and the turntable 12 that are close to each other are bonded with an anti-slip layer. The anti-slip layer is made of rubber. The rubber anti-slip layer has good elasticity and adhesion, which can increase the friction between the contact surfaces of the back plate 16 and the turntable 12.

[0034] In this invention, the V-shaped groove 3 on the wall of the impregnation tank 2 cooperates with the sliding rod 9 on the surface of the lid 7. When the impregnation tank 4 moves vertically by the lifting assembly, the sliding rod 9 slides along the V-shaped groove 3, which can drive the two lids 7 to slide relative to each other or back to back in the sliding groove 6 through the slider 8, so as to realize the automatic opening and closing of the lids 7 without manual operation, which greatly improves the convenience of operation when placing and picking up the substrate and saves labor costs.

[0035] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
