Description

Technical Field

[0001] This utility model relates to the field of porous vacuum silicon technology, and in particular to a drying and molding device for porous vacuum silicon. Background Technology

[0002] Porous vacuum silicon, as a new type of super thermal insulation material, has excellent thermal insulation performance and light weight, while maintaining good stability. Drying is a crucial step in the processing of silicon materials.

[0003] Existing drying and molding equipment for porous vacuum silicon still has some shortcomings in practical use:

[0004] During the drying and molding process of porous vacuum silicon, the vacuum drying chamber is subjected to vacuum treatment and heating to dry the porous vacuum silicon. However, during the vacuum heating process, as water vapor evaporates, the not-yet-fully-formed and stable pores inside the porous vacuum silicon do not receive moisture support and are prone to collapse, causing deformation inside the porous vacuum silicon. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where, during vacuum heating, as water vapor evaporates, the porous vacuum silicon, whose internal voids are not yet fully formed and stable, cannot be supported by moisture and is prone to collapse, causing deformation within the porous vacuum silicon. Therefore, this invention proposes a drying and forming device for porous vacuum silicon.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A drying and molding device for porous vacuum silicon includes a device body. A placement rack is provided within the device body. Four first connectors are fixedly connected to the bottom of the placement rack. Four second connectors are fixedly installed on the inner bottom wall of the device body. A connecting block is provided between adjacent first and second connectors. The connecting block is rotatably connected to both the second and first connectors via a rotating shaft. A mating rod is fixedly installed at the bottom of the placement rack. Two support seats are fixedly installed on the inner bottom wall of the device body. A connecting shaft rotatably passes between the two support seats. Connecting frames are fixedly connected to both ends of the connecting shaft. Each of the two connecting frames has a second mating groove, and the two ends of the mating rod slide within the two second mating grooves respectively.

[0008] In one possible design, a drive motor is fixedly connected inside the device body, a gear is fixedly sleeved on the outer wall of the output shaft of the drive motor, a gear disk is rotatably connected inside the device body, and the gear meshes with the gear disk, a sliding shaft is fixedly connected to one side of the gear disk, a mating frame is fixedly sleeved on the outer wall of the connecting shaft, a first mating groove is provided in the mating frame, and the sliding shaft passes through the first mating groove.

[0009] In one possible design, sliding grooves are provided on both inner walls of the device body, and a clearance block is fixedly slidably connected in each of the two sliding grooves. The two sides of the placement frame abut against the two clearance blocks respectively. Two push blocks are fixedly connected to the top of each of the two clearance blocks, and the push blocks slide within the device body. Four springs are provided within the device body, and one end of each of the four springs is fixedly connected to the device body, while the other end of the springs is fixedly connected to the corresponding push block.

[0010] In one possible design, a U-shaped frame is fixedly installed inside the placement rack to support the porous vacuum silicon.

[0011] In one possible design, a vacuum pump is fixedly installed inside the device body, with the inlet of the vacuum pump extending into the interior of the device body and the outlet of the vacuum pump extending to the outside of the device body. Infrared heating tubes are fixedly installed on both inner walls of the device body.

[0012] In one possible design, two sealed doors are hinged to one side of the device body.

[0013] In this application, multiple sample holders containing porous vacuum silicon samples are placed on a display rack. The sealed door is closed, and the vacuum pump inside the equipment body is activated to evacuate the equipment body to a certain vacuum state. The heating plate is then activated to heat and evaporate the moisture inside the porous vacuum silicon samples. The drive motor is then activated, and the output shaft of the drive motor drives the gear to rotate. The gear meshes with the gear plate, causing the sliding shaft on one side of the mating rod to rotate in a circular motion. The sliding shaft is inserted into the first mating groove, and the mating frame drives the connecting shaft to rotate reciprocally. The two ends of the connecting shaft are supported by support seats, which in turn drive the connecting frame. The swing mechanism, through the cooperation of the second mating groove and the mating rod, pushes the placement frame to swing back and forth. The bottom of the placement frame is connected to the first and second connecting heads respectively by four connecting blocks, which realize the swing and clearance. During the left and right swing, the placement frame will push the two clearance blocks in turn, thereby compressing the springs. When the placement frame moves away from the pushing block on one side, the spring on the same side is released. When the placement frame swings, it will cause the water inside the pores in the porous vacuum silicon to sway left and right, accelerating the evaporation of water vapor. The water swaying between the pores can prevent the pores from collapsing.

[0014] Beneficial effects: In this utility model, the drying and molding equipment for porous vacuum silicon has a transmission mechanism that enables the reciprocating swing of the placement rack. This swing not only helps the porous vacuum silicon to be heated more evenly during the drying process, but also promotes the uniform evaporation of moisture inside the sample, avoiding the problem of uneven drying in certain areas.

[0015] In this utility model, the drying and molding equipment for porous vacuum silicon has a swinging rack that causes the moisture inside the porous vacuum silicon to slosh around. During the sloshing process, the moisture can fill the gaps inside the porous vacuum silicon that have not yet been fully stabilized, effectively preventing the collapse of the gaps, maintaining the stability of the porous structure, and helping to improve the quality and performance of the product.

[0016] This invention achieves a highly efficient, uniform, stable, and intelligent drying and molding process, providing strong support for the production and application of porous vacuum silicon. At the same time, the equipment also has broad application prospects and potential for sustainable development. Attached Figure Description

Four first connectors 8 are fixedly connected to the bottom of the placement rack 3, and four second connectors 9 are correspondingly fixedly installed on the bottom inner wall of the device body 1. In order to realize the flexible movement and positioning of the placement rack 3, connecting blocks 5 are set between adjacent first connectors 8 and second connectors 9.

In addition, a mating rod 17 is fixedly installed at the bottom of the placement rack 3, and two support seats 12 are fixedly installed on the bottom inner wall of the device body 1. A connecting shaft 13 rotatably passes between the two support seats 12. Both ends of the connecting shaft 13 are fixedly connected to connecting frames 4, and both ends of the connecting frames 4 are provided with second mating grooves 20. The two ends of the mating rod 17 slide in the two second mating grooves 20 respectively, thereby realizing the stable support and sliding adjustment of the placement rack 3.

[0025] Reference Figure 4 and Figure 5 A drive motor 15 is fixedly connected inside the device body 1. A gear 19 is fixedly sleeved on the outer wall of the output shaft of the drive motor 15. A gear disk 14 is rotatably connected inside the device body 1, and the gear 19 meshes with the gear disk 14. A sliding shaft 18 is fixedly connected to one side of the gear disk 14. A mating frame 21 is fixedly sleeved on the outer wall of the connecting shaft 13. A first mating groove 16 is provided in the mating frame 21, and the sliding shaft 18 passes through the first mating groove 16. When the drive motor 15 is started, it can drive the gear 19 to rotate, and then through the transmission of the gear disk 14 and the sliding shaft 18, the rotation adjustment of the connecting shaft 13 and the placement frame 3 can be realized, which facilitates the uniform drying of the porous vacuum silicon material.

[0026] Reference Figure 2 and Figure 3 The inner walls of both sides of the device body 1 are provided with sliding grooves 6. Each sliding groove 6 has a sliding relief block 7 fixedly connected to it. The two sides of the placement frame 3 respectively abut against the two relief blocks 7.
