Description

Technical Field

[0001] The invention relates to the technical field of aerogel preparation, and in particular to a dispersing device for a modified aerogel composite material. Background Art

[0002] Aerogel, as a material with a unique nanoporous structure, has extremely low density, excellent thermal insulation performance, high specific surface area and other characteristics. It shows great application potential in many fields, such as aerospace, building insulation, new energy, etc. However, the original aerogel often has some performance limitations. In order to meet the diverse needs of different application scenarios, the modification of aerogel becomes a key link. In the preparation process of modified aerogel, mixing is a crucial step. By uniformly mixing aerogel with other modified materials, the performance of aerogel can be effectively improved, such as enhancing its mechanical strength, regulating its pore size distribution, and optimizing its chemical stability.

[0003] When the current modified aerogel composite material dispersion equipment is used, there are significant defects in the mixing method. It mainly relies on a relatively simple structure of mixing and stirring blades to achieve the stirring operation of aerogel and other mixed materials. These stirring blades usually only have basic rotation functions. During the rotation process, the stirring force generated is relatively single and limited. From the perspective of the mixing effect, the rotation of the simple stirring blade can only form a more conventional material flow pattern. In this mode, it is difficult for the material to achieve full and deep mixing in all directions, especially for materials with special physical properties such as aerogel. When the stirring blade rotates at high speed, a strong vortex will be formed in the stirring barrel. These vortices will generate an upward airflow in the middle part of the stirring barrel and a downward airflow in the surrounding part. The low-density aerogel is easily driven by the vortex and rises in the middle part of the stirring barrel instead of sinking to the position of the stirring blade. If the aerogel cannot sink to this area in time, it cannot effectively contact the stirring blade, resulting in uneven mixing, resulting in uneven mixing of the modifier and the aerogel, affecting the performance of the composite material and the preparation efficiency.

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. All other embodiments obtained by ordinary technicians in the field without making creative work based on the embodiments of the present invention shall fall within the scope of protection of the present invention.

[0018] See also Figures 1 to 4 The embodiment of the present invention provides a dispersing device, which is used in the scenario of dispersing and mixing the modified aerogel composite material during the preparation process. In this embodiment, the structure of the dispersing device is improved to have the advantage of efficient mixing. Specifically, taking the preparation of the modified aerogel composite material as an example, as a preferred solution in this embodiment, the dispersing device is specifically a dispersing device for the modified aerogel composite material, which can mix and stir the preparation materials of the modified aerogel composite material.

[0019] See also Figures 1 to 4 The present invention provides a technical solution: a dispersing device for modified aerogel composite materials, which is used in the scenario of mixing and stirring aerogel preparation materials during the preparation process.

[0020] It includes a storage mechanism 2 and a mixing mechanism 6, wherein: The storage mechanism 2 is provided with a storage cavity for storing the materials to be mixed; The mixing mechanism 6 includes a tray 603, a discharge port 604 and a stirring blade 607. The tray 603 is slidably connected in the storage cavity along the extension 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 discharge port 604 is provided on the surface of the tray 603, so that the material to be mixed passes through the discharge port 604 and enters the mixing space to contact the stirring blade 607. It also includes a driving mechanism 5, which is used to drive the tray 603 to slide along the extension direction of the storage cavity and simultaneously rotate the stirring blade 607; When in use, the materials to be mixed (i.e., aerogel and modifier) ​​are first placed in 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; The tray 603 is driven to slide in the storage barrel 201 by the driving mechanism 5, and the stirring blade 607 is driven to rotate. First, the materials to be mixed (i.e., aerogel and modifier) ​​can be squeezed by the tray 603, so that the materials to be mixed are squeezed out 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 cannot be suspended in the stirring barrel due to its low density and high porosity, ensuring that the aerogel can enter the mixing space in time and fully contact with the stirring blade 607. The stirring blade 607 follows the sliding of the tray 603 to stir, and after the materials to be mixed are squeezed out from the discharge port 604, the preliminarily mixed materials can be mixed. The material is further stirred to achieve 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 mixing efficiency, but also effectively solves the problem that the aerogel is not easy to sink and does not contact the stirring blade 607 during the traditional stirring process, ensures the full mixing of the aerogel and the modifier, and improves the preparation quality of the composite material. At the same time, the segmented mixing method allows the aerogel to be gradually and evenly distributed in the modifier without being broken due to the instantaneous high shear force, thereby protecting the microstructure of the aerogel, avoiding damage caused by excessive shear force, and significantly improving the preparation efficiency and uniformity of the aerogel composite material.

[0021] In the above embodiment, as a preferred solution, the storage mechanism 2 includes a storage tube 201 and a heating wire 203, the storage cavity is opened in the storage tube 201, and the heating wire 203 is evenly wound and fixed on the outer wall of the storage tube 201; In this embodiment, the storage cylinder 201 is used to store aerogels and other modifiers, providing 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 by powering on, providing a suitable temperature environment for the material in the storage cylinder 201, effectively avoiding the reduction of material activity due to too low temperature, ensuring that the performance of the aerogel will not be affected by temperature problems during the stirring process, and meeting the strict requirements of the aerogel on the stirring temperature.

[0022] 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.

[0023] 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.

[0024] In the above embodiment, as a preferred solution, a discharge mechanism 3 is also included, and the discharge mechanism 3 includes a discharge pipe 301, a valve 302 and a handwheel 303. The discharge pipe 301 is plugged into the outer wall of the protective tube 1, and one end of the discharge pipe 301 penetrates into the protective tube 1 and is plugged into the outer walls of the storage tube 201 and the isolation tube 202. The valve 302 is connected to the outer wall of the protective tube 1 by bolts and is connected to the discharge pipe 301. The handwheel 303 is fixedly installed above the valve 302. One end of the discharge pipe 301 is plugged into the outer wall of the protective tube 1, and the other end penetrates into the protective tube 1 and is plugged into the outer walls of the storage tube 201 and the isolation tube 202. 301 is a passage for the material discharge device after the mixing is completed, which ensures that the material can be discharged smoothly and is convenient for subsequent processing. The valve 302 controls the opening and closing of the discharge pipe 301, determines when the material is discharged, ensures that the material will not leak during the mixing process, and can be accurately controlled when the discharge is required. The opening and closing of the valve 302 can be easily operated by rotating the hand wheel 303, which is convenient for the operator to control the discharge process and improve the convenience of operation. The upper discharge mechanism 3 is used to directly deliver the material into the interior of the device, ensuring that the material can accurately enter the storage cylinder 201 for mixing, thereby facilitating the staff to perform the feeding operation; Specifically, the discharge mechanism 3 is only one embodiment, and there may be another embodiment. After the tray 603 is disassembled, the material to be mixed is placed in the storage chamber, and then dispersed and stirred. After the dispersion and stirring are completed, the tray 603 is disassembled, and then the dispersed and mixed material in the storage chamber is taken out. This is an existing well-known technology and no improvement is made here, so it will not be described in detail.

[0025] In the above embodiment, as a preferred scheme, a sealing structure 4 is also included, and the sealing structure 4 includes a cover plate 401 and a fixing bolt 402. The bottom of the cover plate 401 is detachably connected to the top of the protective tube 1. A plurality of fixing bolts 402 are threadedly penetrated through the top of the cover plate 401. One end of the fixing bolt 402 passes through the cover plate 401 and is threadedly connected to the top of the protective tube 1. The cover plate 401 is used to seal the top of the protective tube 1 during the mixing process to prevent the material from overflowing during the stirring process. At the same time, the internal temperature can be kept stable to prevent external impurities from entering. The fixing bolt 402 is threadedly penetrated through the top of the cover plate 401, and the protruding end is threadedly connected to the top of the protective tube 1, so that the cover plate 401 is firmly fixed on the protective tube 1, ensuring the sealing performance of the sealing structure 4 and preventing material leakage and external interference.

[0026] In the above embodiment, as a preferred solution, the driving mechanism 5 includes a motor 501, a driving shaft 502 and a guide groove 503. One end of the driving shaft 502 is connected to the output end of the motor 501 through a key. Two guide grooves 503 are respectively provided on both sides below the outer surface of the driving shaft 502. The outer surface of the driving shaft 502 is provided with threads above the guide grooves 503. The setting of the motor 501 can provide power for the rotation of the driving shaft 502, and then the mutual cooperation of the threads can drive the fixed plate 601 to float up and down, and the guide grooves 5 The setting of 03 can play a guiding role, and can realize the up and down floating of the tray 603 in the storage cylinder 201 during the rotation of the driving shaft 502, providing power for the extrusion of the raw materials and the up and down floating stirring of the stirring blade 607, thereby enhancing the mixing effect. With the help of the mutual cooperation between the driving shaft 502 and the fixed plate 601, when the tray 603 touches the bottom of the storage cylinder 201, the damping bearing starts to rotate, ensuring the position of the tray 603 and the fixed plate 601, while not affecting the rotation of the stirring blade 607; The motor 501 is detachably fixed to the surface of the cover plate 401 by bolts. The motor 501 is a known technology and is only referenced here without any improvement, so it will not be described in detail. It can rotate forward or reverse, and the output end of the motor 501 can be controlled to switch between forward and reverse as needed.

[0027] In the above embodiment, as a preferred solution, the mixing mechanism 6 also includes a fixed disk 601 and a connecting rod 602. The bottom ends of the four connecting rods 602 are respectively threadedly connected to the top of the tray 603. The bottom of the fixed disk 601 is detachably connected to the tops of the four connecting rods 602. One end of the four connecting rods 602 passing through the fixed disk 601 is threadedly connected to a fixing nut. A damping bearing is fixedly installed in the middle of the top of the fixed disk 601. The inner ring of the damping bearing is threadedly connected to the outer surface of the driving shaft 502. The driving shaft 502 can be fixed to the fixed disk 601. The threaded driving force generated during the rotation of the shaft 502 is transmitted to the tray 603, and then the remaining components are driven to slide up and down with the help of the connecting rod 602, thereby ensuring the stability of each component during operation. The bottom end of the connecting rod 602 is threadedly connected to the four corners of the top of the tray 603, and the top end is detachably connected to the four corners of the bottom of the fixed plate 601, and one end of the fixed plate 601 is threadedly connected to a fixing nut. The connecting rod 602 realizes a stable connection between the fixed plate 601 and the tray 603, thereby ensuring the movement accuracy of the tray 603 in the storage tube 201.

[0028] In the above embodiment, as a preferred solution, the fixed disk 601 is slidably connected in the storage cavity along the extension direction of the storage cavity, and the outer ring of the fixed disk 601 is sealed and connected to the inner wall of the storage cavity through a sealing ring, and the sealing ring provided on the fixed disk 601 is sealed and connected to the storage cavity. When the fixed disk 601 slides along the extension direction of the storage cavity (that is, the fixed disk 601 is Figure 2 When the view slides downward, or it can be understood that the fixed disk 601 moves in a 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 squeezing of the tray 603 and the shearing of the aerogel and the modifier by the stirring blade 607, the aerogel and the modifier will produce bubbles, as well as the bubbles originally contained in the raw materials) are quickly discharged. At the same time, the gas is lighter than the aerogel and the modifier, and will be between the fixed disk 601 and the stirring blade 607 to form a gas space. The gas space will squeeze the aerogel and the modifier, thereby further enabling the aerogel and the modifier materials to accumulate at the bottom of the storage cylinder 201, or it can be understood as the mixing space located above the tray 603, that is, the position where the stirring blade 607 is located, so that it is more convenient for the stirring blade 607 to stir and mix the materials, thereby further improving the mixing efficiency.

[0029] In the above embodiment, as a preferred solution, the mixing mechanism 6 also includes a limit frame 605, a guide block 606 and a limit ring 608. The limit frame 605 is detachably connected to the outer wall of the connecting rod 602, the guide block 606 is fixedly connected to the inner wall of the stirring blade 607, the outer surface of the guide block 606 is slidably connected to the inner wall of the guide groove 503, and the limit ring 608 is threadedly connected to the outer surface of the connecting rod 602. Through the coordinated arrangement of the limit ring 608 and the limit frame 605, the stirring blade 607 can be limited when it rotates in the storage chamber. The guide groove 503 and the guide block 606 cooperate with each other to drive the stirring blade 607 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, the connection between the driving shaft 502 and the guide block 606 and the driving shaft 502 and the fixed plate 601 can reduce the use of power source, reduce energy loss and reduce operating steps, thereby further improving convenience.

[0030] In the present invention, the working steps of the device are as follows: 1. First, by rotating the hand wheel 303 in the upper discharge mechanism 3, the valve 302 is opened to feed the material into the storage cylinder 201. After the feeding is completed, the hand wheel 303 is rotated in the opposite direction to close the valve 302 to ensure that the material does not flow back outward; 2. Next, 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 a suitable range.

[0031] 3. Start the motor 501 to drive the driving shaft 502 to rotate. The threads cooperate with each other to drive the fixed plate 601, the connecting rod 602 and the tray 603 to move up and down in the protective tube 1. The tray 603 squeezes the raw materials in the storage tube 201 during the movement, and the raw materials are squeezed out from the discharge port 604 to achieve preliminary mixing. At the same time, the stirring blade 607 starts to rotate under the drive between the guide block 606 and the guide groove 503. The stirring blade 607 is driven by the tray 603 to perform floating stirring up and down, and further stirs the preliminary mixed materials squeezed out from the discharge port 604, so that the materials are fully mixed at different positions, thereby improving the stirring and mixing effect; 4. Then, continue stirring for a period of time to ensure that the materials are evenly mixed. The forward and reverse rotations of the motor 501 can be adjusted according to actual conditions to achieve the best mixing effect; 5. Finally, after the mixing is completed, turn off the heating wire 203 and the motor 501, and open the valve 302 by rotating the hand wheel 303 in the discharge mechanism 3, and the mixed material is discharged through the discharge pipe 301 or the cover plate 401 and the tray 603 are disassembled and taken out for subsequent processing.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
