Description

Technical Field

[0001] The utility model relates to the technical field of aerogel, and specifically relates to a sol impregnation device for aerogel thermal insulation materials. Background Art

[0002] An impregnation device is a device widely used in the industrial and scientific research fields, mainly used for immersing or penetrating liquid components into solid materials. In the field of forming aerogel composite thermal insulation materials by impregnating fibers with sol, existing laboratory-level impregnation devices usually include a simple impregnation tank containing a liquid medium to be impregnated. After placing the fiber products, the sol is manually pressed to be immersed as much as possible while removing the air bubbles in the fiber products.

[0003] In the prior art, manual pouring of the liquid medium and manual pressing are often used for preparation, but there are often problems such as uneven manual pressing force, resulting in that the positions of the fiber products with greater pressure are immersed in the sol first, while the positions with smaller pressure are immersed in the sol later, thus causing deformation of the fiber products and resulting in uneven surfaces and poor uniformity of the final formed samples. Summary of the Utility Model

[0004] The utility model aims to overcome the deficiencies in the prior art and provides a sol impregnation device for aerogel thermal insulation materials.

[0007] On the basis of the above technical solutions, the following further technical solutions may be available:

[0008] A liquid inlet buffer tank is arranged on the base on the other side of the impregnation tank; a liquid delivery pipe is connected to one side wall of the liquid inlet buffer tank through a liquid delivery joint; one end of the liquid delivery pipe is communicated with the lower part of the impregnation tank through a liquid inlet joint; a sol liquid injection pipe is connected to the side wall on the other side of the liquid inlet buffer tank, and the liquid delivery joint and the sol liquid injection pipe are not in the same direction.

[0009] A coaxial bracket connected to the output shaft of the lifting device is arranged on the pressing plate. The coaxial bracket includes a pressing ring arranged on the upper surface of the pressing plate; a group of support rods are evenly distributed on the pressing ring; the upper ends of all the support rods are connected to the same mounting seat; the upper end of the mounting seat is fixedly connected to the output shaft of the lifting device, and the mounting seat, the pressing ring and the pressing plate are coaxially distributed.

[0010] A limiting and lifting groove corresponding to the infusion tube is connected between the liquid inlet buffer tank and the impregnation tank.

[0011] Advantages of the utility model:

[0012] The utility model has the advantages of simple structure, convenient use, uniform force on the pressing plate, uniform pressure on the fiber product during the sol impregnation operation, excellent flatness and good uniformity on the surface of the final sample, and can quickly and efficiently obtain qualified products; by arranging the liquid inlet buffer tank and the infusion tube, the liquid medium enters the impregnation tank, reducing the possibility of liquid splashing caused by manual pouring.

[0014] Figure 2 is the side view of Embodiment 2 of the utility model. Detailed implementation manners Embodiment

[0015] As Figure 2 shown, a sol impregnation device for aerogel thermal insulation material includes a base 1, on which a circular impregnation tank 3 is detachably inserted. A clamping claw 2a corresponding to the outer wall of the base of the impregnation tank 3 is connected to the insertion groove 2 of the base 1. The clamping claw is a prior art and will not be described in detail here.

[0016] An L-shaped bracket 4 is fixedly connected to the base 1 on one side of the impregnation tank 3. It includes a vertical section and a horizontal section. A longitudinally telescopic lifting device 5a is connected to the lower surface of one end of the horizontal section. The lifting device 5a is a hydraulic cylinder or a pneumatic cylinder or an electric telescopic rod in the prior art. In this application, a hydraulic cylinder is used.

[0017] The output shaft of the hydraulic cylinder is coaxially distributed with the impregnation tank 3. A circular pressing plate 5 is installed at the lower end of the output shaft of the hydraulic cylinder. The pressing plate 5 is a perforated plate structure, and there is no hole at the installation position of the output shaft and the pressing plate 5. Embodiment

[0018] As Figure 1 and 2 shown, a sol impregnation device for aerogel thermal insulation material includes a base 1, on which a circular impregnation tank 3 is detachably inserted. A clamping claw 2a corresponding to the outer wall of the base of the impregnation tank 3 is connected to the insertion groove 2 of the base 1. The clamping claw is a prior art and will not be described in detail here.

[0019] On the base 1 on one side of the impregnation tank 3, an L-shaped bracket 4 is fixedly connected. It includes a vertical section and a horizontal section. On the lower surface of one end of the horizontal section, a longitudinally telescopic lifting device 5a is connected. The lifting device 5a is a hydraulic cylinder or a pneumatic cylinder or an electric telescopic rod in the prior art. In this application, a hydraulic cylinder is adopted.

[0020] The output shaft of the hydraulic cylinder is coaxially distributed with the impregnation tank 3. A coaxial bracket is installed at the lower end of the output shaft of the hydraulic cylinder. The coaxial bracket includes a pressure ring 9 installed on the upper surface of the pressing plate 5. A group of support rods 11 are evenly distributed on the pressure ring 9. The upper ends of all the support rods 11 are connected to the same mounting seat 10. The upper end of the mounting seat 10 is fixedly connected to the output shaft of the lifting device 5a. The mounting seat 10, the pressure ring 9 and the pressing plate 5 are coaxially distributed. The pressure ring 9 does not block the holes on the pressing plate 5.

[0021] On the base 1 on the other side of the impregnation tank 3, a liquid inlet buffer tank 6 is provided. A support column 6a is connected between the bottom of the liquid inlet buffer tank 6 and the base 1. On one side wall of the liquid inlet buffer tank 6, a liquid delivery pipe 7 is connected through a liquid delivery joint. One end of the liquid delivery pipe 7 communicates with the lower part of the impregnation tank 3 through a liquid inlet joint.

[0022] On the other side wall of the liquid inlet buffer tank 6, a sol liquid injection pipe 8 is connected. A switch valve (not shown in the figure) is also provided on the sol liquid injection pipe 8. The liquid delivery joint and the sol liquid injection pipe 8 are not in the same direction, so that the liquid entering the liquid inlet buffer tank 6 from the sol liquid injection pipe 8 can smoothly enter the liquid delivery pipe 7, avoiding the surging of the liquid.

[0023] A limit supporting groove 12 corresponding to and cooperating with the liquid delivery pipe 7 is connected between the liquid inlet buffer tank 6 and the impregnation tank 3. The liquid delivery pipe 7 is a flexible pipe and is distributed in an arc shape. The limit supporting groove 12 is also distributed in an arc shape. The liquid delivery pipe 7 is located in the limit supporting groove.

[0024] Working process:

[0025] First, open the switch valve so that the sol liquid enters the impregnation tank through the liquid inlet buffer tank and then the liquid delivery pipe. When the liquid level in the impregnation tank rises to a certain height, close the switch valve. Start the lifting device, retract the output shaft of the hydraulic cylinder to the shortest. At this time, the pressing plate 5 rises to the highest. Then put the fiber product into the impregnation tank, and then start the hydraulic cylinder to extend the output shaft downward, driving the pressing plate 5 to smoothly press the whole fiber product into the sol liquid at the same time. Since the whole fiber product is pressed into the sol liquid at the same time, the problem of uneven compression of the fiber product when it is pressed into the sol liquid, resulting in its deformation, is avoided, effectively ensuring the flatness of the surface of the final sample.
