Description

Technical Field

[0001] This invention belongs to the field of crushing equipment technology, specifically, it relates to a crushing device for the production of aerogel powder. Background Technology

[0002] Aerogels are nanoscale porous solid materials formed by replacing the liquid phase in a gel with gas through a sol-gel method and a specific drying process. Aerogel products are typically prepared from aerogel powder through processes such as sol-geling, gelation, and drying. Aerogel powder is prepared by mechanically pulverizing aerogel. Powdered aerogel is easier to handle and store, and it can be more easily dispersed in solvents, facilitating subsequent processing and applications. Furthermore, powdered aerogel is easier to package and transport.

[0003] In the production of aerogel powder, the uniformity of aerogel powder particle size directly affects the quality of the aerogel product. Therefore, it is necessary to sieve the aerogel powder after grinding to maintain the uniformity of particle size as much as possible. Existing grinding methods, such as ball mill grinding, air jet milling, and ultrasonic milling, all involve sieving the aerogel powder through sieves or sieve plates after grinding. However, this sieving method makes it easy for aerogel powder to adhere to the sieves or sieve plates, causing blockages. This requires frequent replacement and cleaning by workers, resulting in a significant workload. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a crushing device for aerogel powder production, thereby solving the technical problem that existing crushing devices require sieving of aerogel powder using screens or sieve plates after crushing, which causes the aerogel powder to easily adhere to the screens or sieve plates, resulting in clogging of the screens or sieve plates.

[0005] To achieve the aforementioned objective, the present invention provides a crushing device for aerogel powder production, comprising: The shell is a hollow cylindrical structure. An overflow port extending vertically from the center of the top of the shell and communicating with the interior of the shell is provided. A feed port communicating with the interior of the shell is provided on the side wall of the shell. The crushing assembly includes a mounting block disposed inside the housing and capable of horizontal rotation. The mounting block is provided with a plurality of crushing blades for crushing aerogel. The crushing blades are horizontally arranged, with the lower side of the crushing blade being the cutting edge side. The cutting edge side is inclined towards the rotation direction of the mounting block. By rotating the mounting block, the crushing blades can rotate synchronously. During the rotation of the crushing blades, the aerogel can be crushed, and centrifugal force and upward lift can be provided to the aerogel so that the crushed aerogel powder can overflow from the overflow port. A first driving component is connected to the mounting block in a transmission manner, and the first driving component is used to drive the mounting block to rotate so that the crushing blade rotates.

[0006] Compared with the prior art, the advantages of the present invention include: (1) The present invention provides a crushing device for aerogel powder production with fewer parts, a relatively simple structure, convenient maintenance, and relatively low production cost.

[0007] (2) The present invention provides a crushing device for producing aerogel powder. The blade side of the crushing blade is inclined towards the rotation direction of the mounting block. During the rotation of the mounting block, the blade side can be inserted into the aerogel in a wedge manner, so that the aerogel can be cut better during continuous rotation. In addition, the inclined angle can also apply an upward lifting force to the aerogel powder, which helps the aerogel powder to overflow from the top overflow port.

[0008] (3) The crushing device for aerogel powder production provided by the present invention, under the action of centrifugal force, large particles, due to their larger mass, will be subjected to a greater centripetal force and are therefore more easily thrown towards the inner wall of the shell, while small particles, due to their smaller mass, are less affected by centrifugal force and are therefore more likely to float in the central area or above the shell. Furthermore, due to the special properties of aerogel, namely that aerogel is one of the least dense solids in the world and extremely lightweight, the crushed aerogel powder will gather in the central area of ​​the shell and can be discharged from the overflow port under the action of centrifugal force and lift.

[0009] (4) The aerogel powder production crushing device provided by this invention, due to the different sizes of particles under centrifugal force, is affected by centrifugal force differently. Therefore, the aerogel powder discharged from the overflow port after crushing is crushed to a certain degree. Thus, the sieving function is automatically realized. Compared with existing ball mill grinding, airflow impact crushing, and ultrasonic crushing, the aerogel powder does not need to be sieved by screens or sieve plates after crushing, thereby reducing the possibility of aerogel powder clogging the screens and sieve plates. It also eliminates the need for staff to replace and clean them at any time, reducing the workload of the staff.

[0010] (5) The present invention provides a crushing device for producing aerogel powder, wherein the crushing and screening operations are carried out simultaneously. After the aerogel is crushed, it is discharged from the overflow port. The crushed aerogel will not be crushed again because it is discharged in time. The subsequent crushed aerogel is the aerogel that has not met the screening standard, thereby improving the crushing efficiency.

[0011] Furthermore, the housing is provided with an adjustment component, which can provide adjustment holes of different sizes. The adjustment holes are coaxially arranged with the overflow port, and the adjustment holes of different sizes can close the overflow port to different degrees.

[0012] In this invention: (1) By adjusting the different sizes of the adjustment holes provided by the adjustment components, the overflow port can be closed to different degrees. Users can flexibly adjust the effective opening size of the overflow port according to actual needs. Since the distribution of aerogel powder with different degrees of pulverization is inconsistent inside the shell (i.e., the particle size decreases from the center to the outside), the design of different sizes of adjustment holes will enable the device to adapt to the production needs of aerogel powder with different particle sizes.

[0013] (2) Since the regulating hole and the overflow port are set on the same axis, the regulating hole is always located at the center of the shell when switching between different sizes of the regulating hole, so that when screening aerogel powder, the aerogel powder that has reached the degree of crushing can be discharged from the overflow port in a rapid and uniform manner.

[0014] (3) By adjusting the size of the overflow port, the rate at which powder overflows from the device can be controlled, thereby optimizing production efficiency. At the same time, the overflow rate is adapted to the sieving of aerogel powder. If the degree of grinding is high and the particle size of aerogel powder is low, the grinding time is longer, so the overflow rate is relatively slower and the required overflow port is smaller. The sieving of finer aerogel powder will also make the overflow port smaller, and the two are compatible. If the degree of grinding is low and the particle size of aerogel powder is high, the grinding time is shorter, so the overflow rate is relatively faster and the required overflow port is larger. The sieving of coarser aerogel powder will also make the overflow port larger, and the two are also compatible.

[0015] (4) Because the overflow port size can be flexibly adjusted, the device can be applied to a variety of different aerogel powder production scenarios, which improves the utilization rate and versatility of the equipment.

[0016] Furthermore, the adjustment assembly includes a rotating plate disposed inside the housing and capable of rotating relative to the housing. The rotating plate is provided with a regular polygonal slide rail composed of at least three strip slide rails. An adjustment plate is slidably fitted on each slide rail. The multiple adjustment plates are in the shape of an isosceles triangle with the same angle at one end. The sum of the angles of the multiple adjustment plates is equal to 360 degrees. The opposite sides of each pair of adjacent adjustment plates abut against each other. The rotating plate is provided with a mounting plate on its top. The rotating plate can rotate relative to the mounting plate. The mounting plate is fixed inside the housing. A limit structure is provided between the mounting plate and the adjusting plate. Through the limit structure, the rotation of the rotating plate can drive the adjusting plate to slide on the corresponding strip rail. The housing is provided with a second driving component for driving the rotating plate to rotate. The rotating plate is driven to rotate by the second driving component so that the multiple adjustment plates slide along the corresponding strip slide rails and the opposite sides of each pair of adjacent adjustment plates always remain in contact. During the sliding process of the multiple adjustment plates, the adjustment holes of different sizes are formed in the middle.

[0017] Furthermore, the adjustment assembly includes a mounting plate horizontally disposed inside the housing. The mounting plate has an opening communicating with the overflow port. The mounting plate is provided with a plurality of adjustment plates arranged in a circumferential array about the opening. The plurality of adjustment plates are slidably connected to the mounting plate along the diameter direction of the opening. The plurality of adjustment plates each have adjustment holes of different diameter sizes. By driving the plurality of adjustment plates to move on the mounting plate, when the adjustment holes of the plurality of adjustment plates are coaxial with the opening, the opening can be closed to different degrees.

[0018] Furthermore, each of the adjustment plates is provided with a push rod. One end of the push rod is connected to the adjustment plate, and the other end extends outward through the housing along the diameter of the opening. An operating rod is provided at the end of the push rod away from the adjustment plate. When the through hole of the adjustment plate is coaxial with the opening, the operating rod abuts against the housing.

[0019] In this invention, the operating lever has three main functions: First, it provides a positioning indicator. The contact state between the operating lever and the housing provides the user with clear visual and tactile feedback, indicating that the adjustment plate has moved to the predetermined position and that the through holes and openings on it are aligned. This helps the user ensure the accuracy of the adjustment. Second, it provides limit protection. The contact between the operating lever and the housing can also prevent the adjustment plate from moving excessively or becoming misaligned to a certain extent. This limit protection mechanism helps maintain the stability and reliability of the adjustment assembly. Third, it serves as an operating handle to facilitate the movement of the push rod.

[0020] Furthermore, the crushing device also includes: Mounting rack; A first conveying mechanism is mounted on a mounting frame and is used to transport aerogel powder discharged from an overflow port. A first transmission component is provided on the first conveying mechanism. The second conveying mechanism is mounted on the mounting frame. When the second conveying mechanism is used to convey the aerogel raw material from the inlet to the inside of the shell, the second conveying mechanism is provided with a second transmission component. A pushing component is mounted on a mounting bracket. The pushing component is used to push a first transmission member or a second transmission member to move so that the first transmission member and the second transmission member are activated. When the first transmission member and the second transmission member are activated, the movement of the first conveying mechanism drives the movement of the second conveying mechanism. When the first transmission member and the second transmission member are not activated, the movement of the first conveying mechanism does not drive the movement of the second conveying mechanism.

[0021] In this invention: (1) The core function of the push assembly, as a linkage structure, is to selectively push either the first or second transmission component so that they interact when needed. When the first and second transmission components are linked through the push assembly, the movement of the first conveying mechanism will drive the second conveying mechanism to move synchronously. This design not only improves the automation level of the entire device and achieves synchronization of raw material conveying and powder discharge, but also improves production efficiency.

[0022] (2) The design of the drive assembly also allows the first and second conveying mechanisms to remain independent when they do not need to be linked. This means that the first conveying mechanism (the mechanism for discharging powder) operates while the second conveying mechanism (the mechanism for conveying raw materials) remains stationary. Since powder discharge is a continuous and relatively slow process, the first conveying mechanism needs to operate continuously. However, the raw material conveying speed is faster than the powder discharge speed, so the second conveying mechanism does not need to continuously convey raw materials. Feeding is only required when the raw materials inside the housing are consumed to a certain extent. The above design can be flexibly adjusted according to production needs, avoiding unnecessary energy consumption and wear.

[0023] Furthermore, a movable plate is provided inside the housing, which is located below the mounting block. A pressure sensor is provided between the movable plate and the bottom of the housing. When the weight of the aerogel material inside the housing changes, the pressure sensor can sense the weight change of the aerogel material through the movable plate. The crushing device also includes a controller, which is signal-connected to the pressure sensor and the pushing component. The pressure sensor transmits pressure signals to the controller, and the controller controls the operation of the pushing component according to the pressure signals. The controller presets a first threshold and a second threshold, where the value of the first threshold is greater than the value of the second threshold. When the value measured by the pressure sensor is less than the second threshold, the controller controls the push component to move so that the first transmission component and the second transmission component interact. The first conveying mechanism drives the second conveying mechanism to move, and the second conveying mechanism conveys raw materials into the housing. When the value measured by the pressure sensor is greater than the preset first threshold, the controller controls the push component to move so that the first transmission component and the second transmission component do not interact. The first conveying mechanism does not drive the second conveying mechanism to move, and the second conveying mechanism stops conveying raw materials into the housing.

[0024] In this invention, a pressure sensor detects real-time weight changes in the aerogel material, and based on a preset threshold, a controller and a drive assembly automatically adjust the operation of the second conveying mechanism to ensure that the aerogel material inside the housing remains at an appropriate level. This automated control mechanism helps improve production efficiency, reduce manual intervention, and may help maintain consistent product quality.

[0025] Furthermore, the housing is provided with a sealing plate for closing the feed inlet, and the housing is provided with an elastic element. When the elastic element is in its natural state, the sealing plate closes the feed inlet. During feeding, the sealing plate is displaced by the compression of the raw material, causing the feed inlet to open. Attached Figure Description

Terms such as “installation,” “connection,” and “joining” shall be interpreted broadly, for example, as fixed connection, detachable connection, mating connection, or integral connection. For a person skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0034] Example 1: Please see Figure 1-9 This embodiment provides a technical solution: a crushing device for aerogel powder production, comprising: a housing 1, a crushing component, and a first driving component 2. (See also...) Figure 3 The shell 1 is a hollow cylindrical structure, meaning it has sufficient internal space to accommodate the aerogel to be crushed and the crushing device for the crushing operation. An overflow port 3 extending vertically from the center of the top of the shell 1 and communicating with the interior of the shell 1 allows the crushed aerogel powder to overflow smoothly from the device after being subjected to sufficient centrifugal force and lift, facilitating subsequent collection and processing. A feed port 4, communicating with the interior of the shell 1, is located on the side wall of the shell 1, allowing the aerogel to enter the device from the outside for crushing.

[0035] See Figure 3 The crushing assembly includes a horizontally rotatable mounting block 5 housed inside the housing 1. The mounting block 5 has several crushing blades 6 for crushing aerogel. The crushing blades 6 are horizontally positioned, with the lower side being the cutting edge. This cutting edge is inclined towards the rotation direction of the mounting block 5. Due to the inclined design of the crushing blades 6, they not only provide cutting force during rotation but also allow the aerogel powder to move upwards along the inclined surface, thus providing an upward lift force. Rotating the mounting block 5 allows the crushing blades 6 to rotate synchronously. During rotation, the crushing blades 6 crush the aerogel and provide centrifugal force and upward lift so that the crushed aerogel powder can overflow from the overflow port 3.

[0036] When the shredder blade 6 rotates and cuts, it provides centrifugal force. Under the action of centrifugal force, large particles, due to their larger mass, experience greater centripetal force and are therefore more easily thrown towards the inner wall of the shell 1. Small particles, due to their smaller mass, are less affected by centrifugal force and are therefore more likely to float in the central area or above the shell 1. At the same time, the inclined setting of the cutting blade also provides additional lift for the aerogel powder. Furthermore, due to the special properties of aerogel—that it is one of the least dense solids in the world and extremely lightweight—the shredded aerogel can be discharged through the overflow port 3.

[0037] See Figure 3 The first driving component 2 is connected to the mounting block 5 via a transmission connection. The first driving component 2 is used to drive the mounting block 5 to rotate, thereby causing the crushing blade 6 to rotate. The first driving component 2 is the power source for the crushing action, enabling the crushing blade 6 to rotate at an appropriate speed and direction, thereby achieving effective crushing of the aerogel.

[0038] Specifically, the first driving component 2 is a motor, which is mounted on the outer wall of the housing 1. A drive shaft is provided at the bottom of the mounting block 5, extending downwards through the housing 1. Both the drive shaft and the motor output shaft are provided with first transmission wheels 28, and the two first transmission wheels 28 are connected by a chain or belt transmission method. In addition, the first driving component can also be other mechanical structures capable of driving an object to rotate.

[0039] See Figure 1-3 In this embodiment, the crushing device further includes a first conveying mechanism 7, a second conveying mechanism 16, and a pushing component 22. The first conveying mechanism 7 is used to transport the aerogel powder discharged from the overflow port 3, and a first transmission component 11 is provided on the first conveying mechanism 7.

[0040] When the second conveying mechanism 16 is used to convey the aerogel raw material from the inlet 4 to the inside of the shell 1, the second conveying mechanism 16 is provided with a second transmission component 19.

[0041] The pushing component 22 is used to push the first transmission member 11 or the second transmission member 19 to move so that the first transmission member 11 and the second transmission member 19 are activated. When the first transmission member 11 and the second transmission member 19 are activated, the first conveying mechanism 7 moves and drives the second conveying mechanism 16 to move. When the first transmission member 11 and the second transmission member 19 are not activated, the movement of the first conveying mechanism 7 does not drive the movement of the second conveying mechanism 16.

[0042] The actuating component 22 is an innovative linkage mechanism whose core function is to selectively actuate either the first transmission component 11 or the second transmission component 19, allowing them to interact when needed. When the first transmission component 11 and the second transmission component 19 are linked through the actuating component 22, the movement of the first conveying mechanism 7 will drive the second conveying mechanism 16 to move synchronously. This design not only improves the automation level of the entire device and achieves synchronization of raw material conveying and powder discharge, but also improves production efficiency.

[0043] Importantly, the design of the actuating component 22 allows the first transmission element 11 and the second transmission element 19 to remain independent when no linkage is required. This means that the first conveying mechanism 7 (the mechanism for discharging powder) operates, while the second conveying mechanism 16 (the mechanism for conveying raw materials) remains stationary. Since powder discharge is a continuous and relatively slow process, the first conveying mechanism 7 needs to operate continuously. However, the raw material conveying speed is faster than the powder discharge speed, so the second conveying mechanism 16 does not need to continuously convey raw materials. Feeding is only required when the raw materials inside the housing 1 are consumed to a certain extent. This design allows for flexible adjustments according to production needs, avoiding unnecessary energy consumption and wear.

[0044] See Figure 1-3Specifically, the first conveying mechanism 7 is a first spiral conveying mechanism, including a first conveying pipe 8 and a first spiral blade 9. The first conveying pipe 8 is mounted on the mounting frame 20. The first spiral blade 9 is disposed inside the first conveying pipe 8 and can rotate relative to the first conveying pipe 8. A third driving component 10 is provided at the end of the first conveying pipe 8. The third driving component 10 is mounted on the mounting frame 20. The third driving component 10 is a motor. The rotating shaft of the first spiral blade 9 extends out of the outside of the first conveying pipe 8 along the length direction of the first conveying pipe 8 and is connected to the output shaft of the motor through a coupling. The overflow port 3 of the housing 1 is connected to the inside of the first conveying pipe 8. The first conveying pipe 8 is provided with a discharge port. The aerogel powder overflowing from the overflow port 3 accumulates inside the first conveying pipe 8. The rotation of the first spiral blade 9 can discharge the aerogel powder accumulated inside the first conveying pipe 8 from the discharge port of the first conveying pipe 8. The first transmission component 11 includes a second transmission wheel 12 fixed on the shaft of the first helical blade 9 and a connecting rod 13 hinged to the shaft of the first helical blade 9. A third transmission wheel 14 is rotatably mounted on the connecting rod 13. The third transmission wheel 14 and the second transmission wheel 12 are connected by a belt drive. A first transmission gear 15 is coaxially fixedly connected to the third transmission wheel 14. The connecting rod 13 can swing relative to the shaft of the first helical blade 9 and can synchronously drive the first transmission gear 15 to swing. At the same time, the third driving component drives the first helical blade 9 to rotate, which can drive the third transmission wheel 14 to rotate through the second transmission wheel 12 and the belt, thereby synchronously driving the first transmission gear 15 to rotate.

[0045] The second conveying mechanism 16 is a second spiral conveying mechanism, including a second conveying pipe 17 and a second spiral blade 18. The second conveying pipe 17 is mounted on the mounting frame 20, and the second spiral blade 18 is disposed inside the second conveying pipe 17 and can rotate relative to the second conveying pipe 17. The inlet 4 of the housing 1 is connected to the feeding end of the second conveying pipe 17. The second conveying pipe 17 is provided with a feeding hopper, through which raw materials can enter the interior of the second conveying pipe 17. Under the rotation of the second spiral blade 18, the aerogel raw materials accumulated inside the second conveying pipe 17 can be conveyed from the feeding end of the second conveying pipe 17 to the interior of the housing 1. The second transmission component 19 includes a second transmission gear 21 fixed on the rotating shaft of the second spiral blade 18. During the rotation and oscillation of the first transmission gear 15, it can mesh with the second transmission gear 21 and drive the second transmission gear 21 to rotate.

[0046] See Figure 1-2The pushing component 22 is an electric push rod 36, which has a fixed end and a pushing end. The fixed end of the electric push rod 36 is hinged to the mounting bracket 20, and the pushing end of the electric push rod 36 is hinged to the axis of the first transmission gear 15. By pushing the first transmission gear 15 to move through the electric push rod 36, the first transmission gear 15 and the second transmission gear 21 can be engaged and disengaged. When engaged, the first conveying mechanism 7 drives the second conveying mechanism 16 to move. When disengaged, the first conveying mechanism 7 does not drive the second conveying mechanism 16 to move.

[0047] See Figure 3 In this embodiment: a movable plate 23 is provided inside the housing 1. The movable plate 23 is located below the mounting block 5. A pressure sensor 24 is provided between the movable plate 23 and the bottom of the housing 1. When the weight of the aerogel material inside the housing 1 changes, the pressure sensor 24 can sense the weight change of the aerogel material through the movable plate 23.

[0048] The crushing device also includes a controller, which is connected to the pressure sensor 24 and the push assembly 22 by signal connection. The pressure sensor 24 transmits pressure signals to the controller, and the controller controls the push assembly 22 to operate according to the pressure signals.

[0049] The controller presets a first threshold and a second threshold. The value of the first threshold is greater than the value of the second threshold. When the pressure sensor 24 measures a value less than the second threshold, the controller controls the push assembly 22 to move so that the first transmission member 11 and the second transmission member 19 interact. The first conveying mechanism 7 drives the second conveying mechanism 16 to move, and the second conveying mechanism 16 conveys raw materials into the housing 1. When the pressure sensor 24 measures a value greater than the preset first threshold, the controller controls the push assembly 22 to move so that the first transmission member 11 and the second transmission member 19 do not interact. The first conveying mechanism 7 does not drive the second conveying mechanism 16 to move, and the second conveying mechanism 16 stops conveying raw materials into the housing 1.

[0050] Specifically, the pressure sensor can be a load cell of model JHBM-M2.

[0051] When the weight of the aerogel material inside the housing 1 changes, the movable plate 23 moves accordingly, and this change is detected by the pressure sensor 24. The pressure sensor 24 transmits the detected pressure signal to the controller. The controller has two preset thresholds: a first threshold and a second threshold, where the value of the first threshold is greater than the value of the second threshold. When the value measured by the pressure sensor 24 is less than the second threshold, it indicates that there is insufficient aerogel material inside the housing 1. At this time, the controller controls the movement of the push assembly 22, causing the first transmission member 11 and the second transmission member 19 to interact, thereby driving the second conveying mechanism 16 to convey material into the housing 1. When the value measured by the pressure sensor 24 is greater than the preset first threshold, it indicates that there is enough or too much aerogel material inside the housing 1. At this time, the controller controls the movement of the push assembly 22, so that the first transmission member 11 and the second transmission member 19 do not interact, thereby stopping the second conveying mechanism 16 from conveying material into the housing 1. The pressure sensor 24 detects the weight change of the aerogel material in real time, and the controller and push assembly 22 automatically adjust the operation of the second conveying mechanism 16 according to a preset threshold to ensure that the aerogel material inside the housing 1 is maintained at an appropriate level. This automated control mechanism helps improve production efficiency, reduce manual intervention, and may help maintain consistent product quality.

[0052] See Figure 3 In this embodiment: a sealing plate 25 for closing the feed inlet 4 is provided inside the housing 1. An elastic element is provided inside the housing 1. When the elastic element is in its natural state, the sealing plate 25 closes the feed inlet 4. When feeding, the sealing plate 25 is displaced under the pressure of the raw material so that the feed inlet 4 opens.

[0053] Specifically, a slide rod 26 is provided inside the housing 1. The slide rod 26 is fixedly connected to the shaft of the second spiral blade 18 near one end of the housing 1. The sealing plate 25 is slidably sleeved on the slide rod 26. A spring 27 is provided between the slide rod 26 and the sealing plate 25. The spring 27 is an elastic element. One end of the spring 27 is connected to the sealing plate 25, and the other end is connected to the slide rod 26.

[0054] See Figure 4-9 In this embodiment: the housing 1 is provided with an adjustment component, which can provide adjustment holes 35 of different sizes. The adjustment holes 35 are coaxially arranged with the overflow port 3. The adjustment holes 35 of different sizes can close the overflow port 3 to different degrees.

[0055] In practical implementation: ① By adjusting the different sizes of the adjustment holes 35 provided by the adjustment component, the overflow port 3 can be closed to different degrees. Users can flexibly adjust the effective opening size of the overflow port 3 according to actual needs. Since the aerogel powders of different pulverization degrees are distributed in different positions inside the shell 1 (i.e., the particle size decreases from the center to the outside), the design of different sizes of the adjustment holes 35 will enable the device to adapt to the production needs of aerogel powders of different particle sizes.

[0056] ② Since the regulating hole 35 and the overflow port 3 are set on the same axis, when switching between regulating holes 35 of different sizes, it is always located at the center of the housing 1, so that when screening aerogel powder, the aerogel powder that has reached the degree of crushing can be discharged from the overflow port 3 in a rapid and uniform manner.

[0057] ③ By adjusting the size of the overflow port 3, the rate at which powder overflows from the device can be controlled, thereby optimizing production efficiency. Simultaneously, the overflow rate is adapted to the aerogel powder sieving. If the degree of grinding is high and the aerogel powder particle size is low, the grinding time is longer, resulting in a slower overflow rate and a smaller overflow port 3 required. Sieving finer aerogel powder will also result in a smaller overflow port; the two are compatible. Conversely, if the degree of grinding is low and the aerogel powder particle size is high, the grinding time is shorter, resulting in a faster overflow rate and a larger overflow port 3 required. Sieving coarser aerogel powder will also result in a larger overflow port; the two are also compatible.

[0058] ④ Because the size of the overflow port 3 can be flexibly adjusted, this device can be applied to a variety of different aerogel powder production scenarios, improving the utilization rate and versatility of the equipment.

[0059] See Figure 4-9 In this embodiment, the adjustment component includes a rotating plate 29, which is disposed inside the housing 1 and can rotate relative to the housing 1. The rotating plate 29 is provided with a regular polygonal slide rail composed of at least three strip slides 30. An adjustment plate 31 is slidably fitted onto each slide rail, allowing the adjustment plate 31 to move along a predetermined path during sliding while maintaining a relatively stable positional relationship. The multiple adjustment plates 31 are arranged in an isosceles triangle shape with the same angle at one end. The sum of the angles of the multiple adjustment plates 31 equals 360 degrees. The opposite sides of each pair of adjacent adjustment plates 31 abut against each other, making it difficult for powder to leak from the gaps between the adjustment plates 31 and improving the accuracy of screening. The strip slides 30 are perpendicular to the vertical axis of the corresponding adjustment plate 31. The sum of the angles of the multiple adjustment plates 31 equals 360 degrees, meaning that when the tips of all the adjustment plates 31 abut against each other at one end, they will completely seal the overflow port 3.

[0060] It is understandable that when there are three strip tracks (30 in total), it is an equilateral triangular slide rail with an adjustment plate angle of 120 degrees; when there are four strip tracks (30 in total), it is a square slide rail with an adjustment plate angle of 90 degrees; when there are five strip tracks (30 in total), it is a regular pentagonal slide rail with an adjustment plate angle of 72 degrees, and so on. In this embodiment, when there are six strip tracks (30 in total), it is a regular hexagonal slide rail with an adjustment plate angle of 60 degrees. It should be noted that the more strip tracks (30 in total), the more sides the regular polygon has, and the closer it is to a circle. Therefore, the adjustment hole 35 is closer to a circle. A circular adjustment hole 35 ensures that the distance from the edge to the center of the adjustment hole 35 is consistent, resulting in a better screening effect.

[0061] Specifically, the strip slide 30 is a groove opened on the top of the rotating plate 29, and a slider is provided in the groove and is slidably connected to the groove. The slider is fixedly connected to the adjusting plate 31.

[0062] A mounting plate 32 is provided on the top of the rotating plate 29. The rotating plate 29 can rotate relative to the mounting plate 32. The mounting plate 32 is fixed inside the housing 1 and serves as the foundation of the entire adjustment assembly. The mounting plate 32 is fixedly installed inside the housing 1 to provide support and positioning for other components. A limit structure is provided between the mounting plate 32 and the adjustment plate 31. Through the limit structure, the rotation of the rotating plate 29 can drive the adjustment plate 31 to slide on the corresponding strip rail.

[0063] The housing 1 is provided with a second driving component for driving the rotating plate 29 to rotate. The second driving component is usually a motor or other type of power device, which provides the necessary torque to drive the rotating plate 29 to rotate. The rotating plate 29 is driven to rotate by the second driving component so that multiple adjusting plates 31 slide along corresponding strip rails, and the opposite sides of each pair of adjacent adjusting plates 31 always remain in contact. During the sliding of the multiple adjusting plates 31, adjusting holes 35 of different sizes are formed in their middle. In this embodiment, the second driving component is an operating rod 37. One end of the operating rod 37 is connected to the rotating plate 29, and the other end extends outward outside the housing 1. The side wall of the housing 1 is also provided with an arc-shaped hole for the operating rod 37 to move. By rotating the operating rod 37, the rotating plate 29 can be driven to rotate synchronously, thereby adjusting the size of the adjusting hole 35. At the same time, the operating rod 37 will slide within the arc-shaped hole.

[0064] When the second drive component is started, the drive rotating plate 29 rotates around the axis of the adjustment hole 35. The rotating plate 29 converts the rotational motion into the sliding motion of the adjustment plate 31 on the strip rail through friction or mechanical connection. Since the rotating plate 29 rotates continuously, the adjustment plate 31 will also slide continuously along the rail, thereby changing the size of the adjustment hole 35. During the sliding process of multiple adjustment plates 31, an adjustment hole 35 of different size will gradually be formed in their middle. The size of the adjustment hole 35 depends on the position of the adjustment plate 31 on the rail.

[0065] Specifically, the mounting plate 32 has multiple strip-shaped through holes 33 arranged in a circular array around the adjustment holes 35. The length direction of the strip-shaped through holes 33 is parallel to the side of the adjustment plate 31. Each strip-shaped through hole 33 is provided with a limit post 34. The limit post 34 is the limiting structure between the mounting plate 32 and the adjustment plate 31. By rotating the adjustment plate 31, the limit post 34 slides in the strip-shaped through hole 33, and at the same time drives the adjustment block to slide on the corresponding strip-shaped slide rail.

[0066] Example 2: See Figure 10-12 The difference between this embodiment and Embodiment 1 is that the adjusting assembly includes a mounting plate 32 horizontally disposed inside the housing 1. The mounting plate 32 has an opening communicating with the overflow port 3. Multiple adjusting plates 31 are arranged in a circumferential array with respect to the opening on the mounting plate 32. These adjusting plates 31 are slidably connected to the mounting plate 32 along the diameter of the opening. This slidable connection allows the adjusting plates 31 to move smoothly on the mounting plate 32, thereby changing their positions relative to the opening. Each of the multiple adjusting plates 31 has adjusting holes 35 of different diameters. The size and shape of these adjusting holes 35 are carefully designed according to actual application requirements, aiming to provide various screening or adjustment possibilities. By driving the multiple adjusting plates 31 to move on the mounting plate 32, when the adjusting holes 35 of the multiple adjusting plates 31 are coaxial with the opening, they can close the opening to varying degrees. Specifically, if the diameter of the adjustment hole 35 of the adjustment plate 31 is small, it can close the opening more, thereby reducing the powder throughput; conversely, if the diameter of the adjustment hole 35 is large, the degree of closure of the opening will be reduced, and the powder throughput will increase accordingly.

[0067] See Figure 10-12In this embodiment, each adjusting plate 31 is provided with a push rod 36. One end of the push rod 36 is connected to the adjusting plate 31, and the other end extends outward along the diameter of the opening and passes through the housing 1. An operating rod 37 is provided at the end of the push rod 36 away from the adjusting plate 31. When the through hole of the adjusting plate 31 is coaxial with the opening, the operating rod 37 abuts against the housing 1. This design has three main functions: First, positioning indication. The abutment state of the operating rod 37 against the housing 1 provides the user with clear visual and tactile feedback, indicating that the adjusting plate 31 has moved to the predetermined position and that the through hole and opening on it have been aligned. This helps the user ensure the accuracy of the adjustment. Second, limit protection. The contact between the operating rod 37 and the housing 1 can also prevent the adjusting plate 31 from moving excessively or misaligning to a certain extent. This limit protection mechanism helps maintain the stability and reliability of the adjusting assembly. Third, it serves as an operating handle to facilitate the movement of the push rod 36.
