Description

Technical Field

[0001] The present invention relates to the technical field of aerogel preparation, and particularly relates to a dispersion device for modified aerogel composite materials. Background Art

[0002] As a material with a unique nano-porous structure, aerogel has characteristics such as extremely low density, excellent heat insulation performance, and high specific surface area, showing great application potential in many fields, such as aerospace, building insulation, new energy, etc. However, raw aerogels often have some performance limitations. To meet the diverse needs of different application scenarios, modifying aerogels has become a crucial step. In the preparation process of modified aerogels, mixing is a vital step. By uniformly mixing aerogels with other modifying materials, the performance of aerogels can be effectively improved, such as enhancing their mechanical strength, regulating their pore size distribution, and optimizing their chemical stability.

[0003] When the current dispersion device for modified aerogel composite materials is in use, there are significant defects in the mixing method. It mainly relies on relatively simple mixing stirring blades to achieve the stirring operation of aerogels and other mixing materials. These stirring blades usually only have basic rotation functions. During rotation, the generated stirring force is relatively single and limited. From the perspective of the mixing effect, the rotation of simple stirring blades can only form a relatively conventional material flow pattern. In this pattern, it is difficult for materials to achieve full and deep mixing in all directions. Especially for materials like aerogels with special physical properties, when the stirring blades rotate at high speed, strong vortices will be formed in the stirring barrel. These vortices will generate upward airflows in the middle part of the stirring barrel and downward airflows in the surrounding parts. Low-density aerogels are easily driven by the vortices and rise in the middle part of the stirring barrel instead of sinking to the position where the stirring blades are located. If the aerogels cannot sink to this area in time, they cannot effectively contact the stirring blades, resulting in uneven mixing, uneven mixing of the modifier and aerogels, affecting the performance of the composite material and also the preparation efficiency. Summary of the Invention

[0014] Optionally, the driving mechanism includes a motor, a driving shaft, and guiding grooves. One end of the driving shaft is key-connected to the output end of the motor. Two guiding grooves are respectively opened on both sides below the outer surface of the driving shaft, and threads are provided on the outer surface of the driving shaft above the guiding grooves.

[0015] Optionally, the mixing mechanism further includes a fixing disk and connecting rods. The bottom ends of the four connecting rods are respectively threadedly connected to the top of the tray.

This process can preliminarily mix the materials to be mixed and at the same time avoid the problem that the aerogel cannot sink due to its low density and high porosity in the stirring barrel, ensuring that the aerogel can enter the mixing space in time and be in full contact with the stirring blade. The stirring blade follows the sliding of the tray to stir, and can further stir the preliminarily mixed materials after the materials to be mixed are extruded from the discharge port, achieving a more uniform mixing effect. When the tray drives the stirring blade to perform cyclic floating stirring, it not only improves the dispersion and mixing efficiency, but also effectively solves the problems that the aerogel is not easy to sink and does not contact the stirring blade during the traditional stirring process, ensuring the full mixing of the aerogel and the modifier, improving the preparation quality of the composite material. At the same time, through the segmented mixing method, the aerogel is allowed to be gradually and evenly distributed in the modifier without being broken due to the instantaneous high shear force, protecting the microstructure of the aerogel and avoiding the damage caused by excessive shear force, significantly improving the preparation efficiency and uniformity of the aerogel composite material.

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figures 1 to 4 , the embodiment of the present invention provides a dispersion device, which is applied to the scenario of dispersing and mixing modified aerogel composite materials during the preparation process. In this embodiment, by improving the structure of the dispersion device, it has the advantage of efficient mixing. Specifically, taking the preparation of modified aerogel composite materials as an example, so as a preferred solution in this embodiment, the dispersion device is specifically a dispersion device for modified aerogel composite materials, which can mix and stir the preparation materials of modified aerogel composite materials.

[0027] Please refer to Figures 1 to 4 , the present invention provides a technical solution: a dispersion device for modified aerogel composite materials, which is applied to the scenario of mixing and stirring aerogel preparation materials during the preparation process.

[0028] It includes a storage mechanism 2 and a mixing mechanism 6, wherein:

[0029] A storage cavity for storing materials to be mixed is provided in the storage mechanism 2;

[0030] The mixing mechanism 6 includes a tray 603, a discharging port 604 and a stirring blade 607. The tray 603 is slidably connected in the storage cavity along the extending direction of the storage cavity, and a mixing space is formed at one end of the tray 603 away from the bottom of the storage cavity. The stirring blade 607 is rotatably connected in the mixing space. The discharging port 604 is opened on the surface of the tray 603 for the materials to be mixed to enter the mixing space through the discharging port 604 and contact the stirring blade 607;

[0031] It further includes a driving mechanism 5, and the driving mechanism 5 is used to drive the tray 603 to slide along the extending direction of the storage cavity while rotating the stirring blade 607;

[0032] During use, the materials to be mixed (i.e., aerogel and modifier) are first placed into the storage cavity, and then the tray 603 is installed so that the materials to be mixed placed in the storage cavity are located between the bottom of the storage cavity and the tray 603;

[0033] Through the driving mechanism 5, the tray 603 is slidably arranged in the storage cylinder 201, and at the same time, the stirring blade 607 is driven to rotate. First, the materials to be mixed (i.e., aerogel and modifier) can be extruded by means of the tray 603, so that the materials to be mixed are extruded from the discharge port 604. This process can preliminarily mix the materials to be mixed, and at the same time avoid the problem that the aerogel suspends in the stirring barrel due to its low density and high porosity, ensuring that the aerogel can enter the mixing space in time and be in full contact with the stirring blade 607. The stirring blade 607 follows the sliding of the tray 603 for stirring, and can further stir the preliminarily mixed materials after the materials to be mixed are extruded from the discharge port 604, achieving a more uniform mixing effect. When the tray 603 drives the stirring blade 607 to perform cyclic floating stirring, it not only improves the dispersion and mixing efficiency, but also effectively solves the problems that the aerogel is not easy to sink and does not contact the stirring blade 607 during the traditional stirring process, ensuring the full mixing of the aerogel and the modifier, improving the preparation quality of the composite material. At the same time, through the segmented mixing method, the aerogel is allowed to be gradually and evenly distributed in the modifier without being broken due to instantaneous high shear force, protecting the microstructure of the aerogel and avoiding damage caused by excessive shear force, significantly improving the preparation efficiency and uniformity of the aerogel composite material.

[0034] In the above embodiment, as a preferred solution, the storage mechanism 2 includes a storage cylinder 201 and a heating wire 203. The storage cavity is opened in the storage cylinder 201, and the heating wire 203 is evenly wound and fixed on the outer wall of the storage cylinder 201;

[0035] In this embodiment, the storage cylinder 201 is used to store aerogel and other modifiers, providing a material storage space for the mixing process. Its stable structure ensures the safe storage of materials before mixing, preventing material leakage or external contamination. The heating wire 203 generates heat through electricity, providing a suitable temperature environment for the materials in the storage cylinder 201, effectively avoiding the reduction of material activity caused by too low temperature, ensuring that the aerogel will not be affected by temperature problems during the stirring process, and meeting the strict requirements of the aerogel for the stirring temperature.

[0036] The tray 603 moves up and down in the storage barrel 201, and can squeeze the raw materials in the storage barrel 201 downward, so that the raw materials are squeezed out from the discharge port 604 (that is, enter the mixing space), and then different materials to be mixed are mixed and extruded to achieve preliminary mixing of the materials, providing a mixing basis for the subsequent further mixing of the stirring blade 607. When the tray 603 squeezes the raw materials, the materials are squeezed out through the discharge port 604 to form a dispersed flow of the materials, which is beneficial to the preliminary mixing of the materials. At the same time, it also provides more stirring paths for the stirring blade 607 to enhance the mixing effect. The stirring blade 607 floats up and down with the tray 603 for stirring. After the materials to be mixed enter the mixing space from the discharge port 604, the stirring blade 607 further stirs the preliminarily mixed materials, so that the materials to be mixed are fully mixed in different directions, which greatly improves the stirring and mixing effect.

[0037] In the above embodiment, as a preferred solution, the storage mechanism 2 also includes an isolation tube 202, which is sleeved on the outer wall of the storage tube 201, and the heating wire 203 is located between the isolation tube 202 and the storage tube 201. The bottom of the isolation tube 202 is fixedly connected with a protective tube 1, and the storage tube 201 is fixedly installed on the inner bottom wall of the protective tube 1. The heating wire 203 is wrapped by the isolation tube 202. On the one hand, it plays a heat insulating role, reduces the heat loss to the protective tube 1, improves the heating efficiency, and reduces energy consumption. On the other hand, it prevents the operator from accidentally contacting the high-temperature heating wire 203 to ensure safe operation. The protective tube 1 serves as the external protective structure of the entire device. The protective tube 1 provides physical protection for the internal storage mechanism 2, the mixing mechanism 6, etc., to avoid interference and damage to the internal precision components by external factors. At the same time, it also plays a certain supporting role to ensure the stability of the entire device.

[0038] In the above embodiments, as a preferred solution, it further includes a discharging mechanism 3. The discharging mechanism 3 includes a discharging pipe 301, a valve 302 and a handwheel 303. The discharging pipe 301 is inserted into the outer wall of the protection cylinder 1. One end of the discharging pipe 301 that penetrates into the protection cylinder 1 is inserted into the outer walls of the storage cylinder 201 and the isolation cylinder 202. The valve 302 is connected to the outer wall of the protection cylinder 1 by bolts and is in communication with the discharging pipe 301. The handwheel 303 is fixedly installed above the valve 302. One end of the discharging pipe 301 is inserted into the outer wall of the protection cylinder 1, and the other end penetrates into the protection cylinder 1 and is inserted into the outer walls of the storage cylinder 201 and the isolation cylinder 202. The discharging pipe 301 is the channel for the discharged material of the device after mixing, ensuring that the material can be smoothly output, facilitating subsequent processing. The valve 302 controls the opening and closing of the discharging pipe 301, determining when the material is discharged, ensuring that the material does not leak during the mixing process and can be accurately controlled when discharging is required. By rotating the handwheel 303, the opening and closing of the valve 302 can be easily operated, facilitating the operator to control the discharging process and improving the operation convenience. The discharging mechanism 3 above is used to directly send the material into the interior of the device, ensuring that the material can accurately enter the storage cylinder 201 for mixing, and then facilitating the staff to perform the feeding operation;

[0039] Specifically, the discharging mechanism 3 is only one implementation manner. There can be another implementation manner. After the tray 603 is removed, the material to be mixed can be placed in the storage cavity, and then dispersion stirring is carried out. After the dispersion stirring is completed, the tray 603 is removed, and then the material that has been dispersed and mixed in the storage cavity is taken out. This is a known technology in the art and will not be improved here, so it will not be elaborated too much.

[0040] In the above embodiments, as a preferred solution, it further includes a sealing structure 4. The sealing structure 4 includes a cover plate 401 and fixing bolts 402. The bottom of the cover plate 401 is detachably connected to the top of the protection cylinder 1. A plurality of fixing bolts 402 are threaded through the top of the cover plate 401. One end of the fixing bolt 402 that penetrates out of the cover plate 401 is threadedly connected to the top of the protection cylinder 1. During the mixing process, the cover plate 401 closes the top of the protection cylinder 1, preventing the material from overflowing during the stirring process, maintaining the internal temperature stability, and avoiding the entry of external impurities. The fixing bolts 402 are threaded through the top of the cover plate 401, and the protruding ends are threadedly connected to the top of the protection cylinder 1, firmly fixing the cover plate 401 on the protection cylinder 1, ensuring the sealing performance of the sealing structure 4, preventing material leakage and external interference.

[0041] In the above embodiments, as a preferred solution, the driving mechanism 5 includes a motor 501, a driving shaft 502, and a guiding groove 503. One end of the driving shaft 502 is key-connected to the output end of the motor 501. Two guiding grooves 503 are respectively formed on both sides below the outer surface of the driving shaft 502. Threads are formed on the outer surface of the driving shaft 502 above the guiding grooves 503. By providing the motor 501, power can be provided for the rotation of the driving shaft 502. Then, through the mutual cooperation of the threads, the fixed disk 601 can be driven to float up and down. The setting of the guiding groove 503 can play a guiding role, enabling the tray 603 to float up and down in the storage cylinder 201 during the rotation of the driving shaft 502, providing power for the extrusion of raw materials and the up-and-down floating stirring of the stirring blades 607, enhancing the mixing effect. With the mutual cooperation between the driving shaft 502 and the fixed disk 601, when the tray 603 touches the bottom of the storage cylinder 201, the damping bearing starts to rotate. While ensuring the positions of the tray 603 and the fixed disk 601, it will not affect the rotation of the stirring blades 607;

[0042] The motor 501 is detachably fixed to the surface of the cover plate 401 by bolts. The motor 501 is a known technology in the art and is only cited here without improvement, so no further elaboration is made. It can rotate forward or backward, and the output end of the motor 501 can be controlled to switch between forward and reverse rotations according to needs.

[0043] In the above embodiments, as a preferred solution, the mixing mechanism 6 further includes a fixed disk 601 and connecting rods 602. The bottom ends of the four connecting rods 602 are respectively thread-connected to the top of the tray 603. The bottom of the fixed disk 601 is detachably connected to the top of the four connecting rods 602. One end of the four connecting rods 602 passing through the fixed disk 601 is thread-connected with a fixing nut. The middle part of the top of the fixed disk 601 is fixedly installed with a damping bearing, and the inner ring of the damping bearing is thread-connected to the outer surface of the driving shaft 502. Through the fixed disk 601, the thread driving force generated during the rotation of the driving shaft 502 can be transmitted to the tray 603. Then, by means of the connecting rods 602, the other components can be driven to slide up and down, ensuring the stability of each component during the working process. The bottom ends of the connecting rods 602 are thread-connected to the four corners of the top of the tray 603, the top ends are detachably connected to the four corners of the bottom of the fixed disk 601, and one end passing through the fixed disk 601 is thread-connected with a fixing nut. The connecting rods 602 achieve a firm connection between the fixed disk 601 and the tray 603, ensuring the movement accuracy of the tray 603 in the storage cylinder 201.

[0044] In the above embodiment, as a preferred solution, the fixed disk 601 is slidably connected in the storage cavity along the extending direction of the storage cavity, and the outer ring of the fixed disk 601 is hermetically connected to the inner wall of the storage cavity through a sealing ring. Through the sealing connection between the sealing ring provided on the fixed disk 601 and the storage cavity, when the fixed disk 601 slides along the extending direction of the storage cavity (that is, when the fixed disk 601 slides downward in the Figure 2 viewing direction, or it can be understood that when the fixed disk 601 moves along the direction away from the motor 501), the air inside the storage cylinder 201 can be compressed, thereby increasing the gas pressure inside the storage cylinder 201, so that the bubbles generated during the dispersion and mixing of the aerogel and the modifier (due to the extrusion of the tray 603 and the shear force generated by the stirring blade 607 on the aerogel and the modifier, bubbles will be generated in the aerogel and the modifier, as well as the bubbles originally contained in the raw materials) can be quickly discharged. At the same time, the gas is lighter than the aerogel and the modifier and will be located between the fixed disk 601 and the stirring blade 607 to form a gas space. The gas space will extrude the aerogel and the modifier, so that the aerogel and the modifier materials can be further stacked at the bottom of the storage cylinder 201, or it can be understood as the mixing space above the tray 603, that is, the position where the stirring blade 607 is located, so as to facilitate the stirring blade 607 to stir and mix the materials, and further improve the mixing efficiency.

[0045] In the above embodiment, as a preferred solution, the mixing mechanism 6 further includes a limiting frame 605, a guiding block 606 and a limiting ring 608. The limiting frame 605 is detachably connected to the outer wall of the connecting rod 602. The guiding block 606 is fixedly connected to the inner wall of the stirring blade 607. The outer surface of the guiding block 606 is slidably connected to the inner wall of the guiding groove 503. The limiting ring 608 is threadedly connected to the outer surface of the connecting rod 602. Through the cooperation of the limiting ring 608 and the limiting frame 605, when the stirring blade 607 rotates in the storage cavity, the stirring blade 607 can be limited to ensure that the stirring blade 607 can further fully stir and mix the raw materials during the up and down movement following the tray 603. Then, through the mutual cooperation between the guiding groove 503 and the guiding block 606, the stirring blade 607 can be driven to rotate when the driving shaft 502 rotates, and at the same time, it will not affect the up and down floating of the stirring blade 607. At the same time, in cooperation with the connection between the driving shaft 502 and the guiding block 606 and the connection between the driving shaft 502 and the fixed disk 601, the use of the power source can be reduced, the energy loss can be reduced, and the operation steps can be reduced, further improving the convenience.

[0046] In the present invention, the working steps of the device are as follows:

[0047] 1. First, rotate the handwheel 303 in the upper discharging mechanism 3 to open the valve 302, and feed the material into the storage cylinder 201. After the feeding is completed, rotate the handwheel 303 in the reverse direction to close the valve 302, ensuring that the material does not flow backward outwards.

[0048] 2. Secondly, turn on the heating wire 203, and adjust the heating power according to the temperature required for aerogel stirring, so that the temperature in the storage cylinder 201 reaches an appropriate range.

[0049] 3. Start the motor 501 to drive the drive shaft 502 to rotate. By utilizing the mutual cooperation between the threads, it drives the fixed disk 601, the connecting rod 602 and the tray 603 to move up and down in the protection cylinder 1. During the movement of the tray 603, the raw materials in the storage cylinder 201 are extruded, and the raw materials are extruded from the discharging port 604 to achieve preliminary mixing. At the same time, the stirring blade 607 starts to rotate under the drive between the guiding block 606 and the guiding groove 503. The stirring blade 607 performs floating up-and-down stirring driven by the tray 603, and further stirs the preliminarily mixed material extruded from the discharging port 604, so that the material is fully mixed at different positions, improving the stirring and mixing effect.

[0050] 4. Then, continue to stir for a period of time to ensure that the material is evenly mixed. The forward and reverse rotation of the motor 501 can be adjusted according to the actual situation to achieve the best mixing effect.

[0051] 5. Finally, after the mixing is completed, turn off the heating wire 203 and the motor 501. Rotate the handwheel 303 in the discharging mechanism 3 to open the valve 302, and the mixed material is discharged through the discharging pipe 301 or taken out after disassembling the cover plate 401 and the tray 603 for subsequent processing.

[0052] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
