A mixing device for aerogel production

Abstract

The application discloses an agglomerate preparation mixing device, which comprises a base, a mounting mechanism fixedly connected to the base, a stirring barrel provided on the mounting mechanism, a rotating hole formed in the stirring barrel, a rotating column rotatably connected to the inside of the rotating hole, a driving mechanism provided on the stirring barrel and used for driving the rotating column, and a rotating shaft provided in the stirring barrel and fixedly connected to one side of the rotating column. The application has the advantage that the driving mechanism drives the rotating shaft to rotate, the rotating shaft drives the first stirring rod to revolve around the rotating shaft when rotating, and the rotating rod revolves with the first stirring rod. Since the gear at the top of the rotating rod is engaged with the annular tooth groove, the gear drives the rotating rod to rotate on its own axis in the through hole, thereby driving the second stirring rod to rotate on its own axis. The second stirring rod, which is staggered with the first stirring rod, revolves and rotates on its own axis at the same time, so that the raw materials can be fully stirred and mixed, and the stirring and mixing effect is effectively improved.

Description

Technical Field

[0001] This invention relates to the field of aerogel mixing equipment technology, specifically a mixing device for aerogel preparation. 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. Examples include gelatin, gum arabic, silica gel, hair, and nails. Aerogels also possess gel properties, namely, expansion, thixotropy, and ionization. Low-density aerogel coatings are generally prepared using a mixing device.

[0003] Current mixing devices for preparing low-density aerogel coatings suffer from insufficient mixing during use, relying solely on a stirring rod in one direction. This results in some raw materials adhering to the inner wall of the mixing tank, making it inconvenient to clean the material adhering to the inner wall and affecting the performance. Summary of the Invention

[0008] Preferably, a baffle is fixedly connected inside the hopper, and multiple sets of discharge slots are evenly distributed around the circumference of the baffle. A turntable is rotatably connected to the bottom center of the baffle, and multiple sets of positioning plates are fixedly connected to the circumference of the turntable. A placement slot is opened on the top of the positioning plate, and a baffle corresponding to the discharge slot is slidably connected inside the placement slot. A first spring is fixedly connected inside the placement slot, and the top of the first spring is fixedly connected to the baffle. The cross-section of the baffle is trapezoidal. A connecting rod is fixedly connected to the bottom center of the turntable, and the bottom of the connecting rod extends out of the discharge port.

[0009] Preferably, the mixing tank has an annular rotating groove on its inner top side, a limiting ring is rotatably connected inside the annular rotating groove, a scraper is fixedly connected to the bottom of the limiting ring, one side of the scraper is in close contact with the inside of the mixing tank, the rotating column has a through groove inside, a push plate is slidably connected inside the through groove, a through groove is opened on one side of the rotating shaft, a connecting rod that cooperates with the scraper is fixedly connected to one side of the push plate, a second spring is fixedly connected inside the through groove, one side of the second spring is fixedly connected to the push plate, a threaded hole is opened on one side of the rotating column, a bolt is threadedly connected inside the threaded hole, and one side of the bolt is in close contact with the push plate.

[0010] Preferably, the driving mechanism includes a connecting frame fixedly connected to the top of the mixing tank, a driving motor fixedly mounted on the connecting frame, and the driving end of the driving motor fixedly connected to the rotating column through a coupling.

[0011] Preferably, a connecting groove is provided on one side of the support column, and a stop block for limiting the positioning block is slidably connected inside the connecting groove.

[0013] The beneficial effects of this invention are as follows: The mixing device for aerogel preparation provided by this invention drives a rotating column to rotate via a drive mechanism, which in turn drives a rotating shaft to rotate. When the shaft rotates, it causes a first stirring rod to revolve around the shaft. Simultaneously, as the rotating rod follows the first stirring rod's rotation, the gear at the top of the rotating rod meshes with an annular toothed groove, causing the gear to rotate within the through-hole, which in turn drives a second stirring rod to rotate. This, combined with the simultaneous rotation and revolution of the second stirring rod, which is staggered with the first stirring rod, ensures thorough mixing of the raw materials, effectively improving the mixing effect. When cleaning the inner wall of the mixing tank is required, the push plate can be moved by tightening the bolts, compressing the second spring and causing the push plate to move. The moving connecting rod causes the rotating column to drive the scraper to revolve around the axis, which can scrape off the raw materials adhering to the inner wall of the mixing tank, making it easier to clean the residual raw materials on the inner wall and making it more convenient to use. Most mixing devices are designed with a hopper-shaped structure for easy discharge. However, conventional mixing components cannot reach the hopper-shaped area to mix, resulting in the raw materials in the hopper-shaped container not being fully mixed. By setting a baffle inside the discharge hopper, the problem of blind spots in the mixing of conventional mixing components can be avoided, thereby further improving the mixing effect of the raw materials in the mixing tank. After the mixing is completed, when discharging, the rotating disk is driven by rotating the connecting rod, so that the baffle moves away from the bottom of the discharge chute, and the raw materials can be discharged through the discharge chute.

Gear 95 is meshed inside the annular toothed groove 10. The top of the mixing tank 3 has an inlet 11, and the bottom of the mixing tank 3 is detachably equipped with a discharge mechanism 12. The base 1 has a receiving groove that can accommodate the mixing tank 3 and the discharge mechanism 12. In use, the raw materials to be mixed are first put into the mixing tank 3 through the inlet 11. The drive motor 62 is started, and the drive motor 62 drives the rotating column 5 to rotate, which in turn drives the rotating shaft 7 to rotate. When the rotating shaft 7 rotates, it drives the first stirring rod 91 to revolve around the rotating shaft 7. At the same time, the rotating rod 93 follows the first stirring rod 91 to revolve. Since the gear 95 at the top of the rotating rod 93 meshes with the annular toothed groove 10, the gear 95 will drive the rotating rod 93 to rotate inside the through hole 92, which in turn drives the second stirring rod 94 to rotate. With the second stirring rod 94, which is staggered with the first stirring rod 91, revolve and rotate simultaneously, the raw materials can be fully mixed.

[0018] The installation mechanism 2 includes multiple sets of support columns 201 fixedly connected to the base 1. A limiting groove 202 is opened on one side of the support column 201. A limiting block 13 adapted to the limiting groove 202 is fixedly connected to the outer surface of the mixing tank 3. The limiting block 13 is slidably connected to the inside of the limiting groove 202. The mixing tank 3 can slide along the vertical direction of the support column 201 through the cooperation of the limiting block 13 and the limiting groove 202. The mixing tank 3 can be pulled out upward to complete the disassembly, reducing the difficulty of disassembly and maintenance of the equipment.

[0019] The bottom of the mixing tank 3 is provided with an annular threaded groove 14. The discharge mechanism 12 includes a hopper 121. A threaded ring 122 is fixedly connected to the top of the hopper 121. The threaded ring 122 is threaded into the inside of the annular threaded groove 14. The bottom of the hopper 121 is provided with a discharge port 123. The connection between the threaded ring 122 and the annular threaded groove 14 at the bottom of the mixing tank 3 makes disassembly and installation easy.

A first spring 130 is fixedly connected inside the placement slot 128. The top of the first spring 130 is fixedly connected to the baffle plate 129. The cross-section of the baffle plate 129 is trapezoidal. A connecting rod 131 is fixedly connected to the bottom center of the turntable 126. The bottom of the connecting rod 131 extends out of the discharge port 123. Rotating the connecting rod 131 drives the turntable 126 to rotate, causing the baffle plate 129 to move away from below the discharge slot 125. The raw material can then be discharged through the discharge slot 125 and the discharge port 123.

[0021] An annular rotating groove 15 is provided on the top side of the interior of the mixing tank 3. A limiting ring 16 is rotatably connected inside the annular rotating groove 15. A scraper 17 is fixedly connected to the bottom of the limiting ring 16. One side of the scraper 17 is in close contact with the interior of the mixing tank 3. A through groove 18 is provided inside the rotating column 5. A push plate 19 is slidably connected inside the through groove 18. A through groove 20 is provided on one side of the rotating shaft 7. A connecting rod 21 that cooperates with the scraper 17 is fixedly connected to one side of the push plate 19. A second spring 22 is fixedly connected inside the through groove 18. One side of the rotating column 5 is fixedly connected to the push plate 19. A threaded hole 23 is provided on one side of the rotating column 5. A bolt 24 is threaded inside the threaded hole 23. One side of the bolt 24 is fitted with the push plate 19. When it is necessary to clean the inner wall of the mixing tank 3, the bolt 24 is turned to push the push plate 19 to slide inside the through groove 18. The second spring 22 is compressed, and the push plate 19 drives the connecting rod 21 to extend. At this time, the rotating column 5 rotates and the connecting rod 21 drives the scraper 17 to revolve around the inner wall of the mixing tank 3 to scrape and clean the raw materials adhering to the inner wall of the mixing tank 3.

[0022] The drive mechanism 6 includes a connecting frame 61 fixedly connected to the top of the mixing tank 3. A drive motor 62 is fixedly installed on the connecting frame 61. The drive end of the drive motor 62 is fixedly connected to the rotating column 5 through a coupling. The rotating column 5 can be rotated by starting the drive motor 62.

[0023] A connecting groove 203 is provided on one side of the support column 201. A stop block 204 for limiting the position of the limiting block 13 is slidably connected inside the connecting groove 203. A mounting bracket 205 is fixedly connected to one side of the support column 201. A third spring 206 is fixedly connected to one side of the mounting bracket 205. One side of the third spring 206 is fixedly connected to the stop block 204. The stop block 204 has a trapezoidal structure. When cleaning and maintenance of the device's interior is required, the stop block 204 can be pulled, causing the stop block to... 204 retracts into the connecting groove 203. Lifting the mixing tank 3 upwards allows the entire mixing tank 3 to be removed for easy cleaning. During installation, align the limiting block 13 with the limiting groove 202 and lower it. The limiting block 13 presses down on the inclined surface of the stop block 204, causing the stop block 204 to retract into the connecting groove 203. When the limiting block 13 moves below the stop block 204, the third spring 206 pushes the stop block 204 out to limit the limiting block 13, thus completing the installation and fixing process. It is convenient to use.

[0024] A cleaning plate 8 for cleaning the discharge mechanism 12 is fixedly connected to the bottom of the rotating shaft 7, and a support leg is fixedly connected to the bottom of the base 1. The support leg is evenly distributed along the edge of the bottom of the base 1 to provide stable support for the entire device. The cleaning plate 8 is in contact with the top of the baffle plate 124. When the device is discharging material, the cleaning plate 8 can rotate synchronously with the rotating shaft 7 to scrape off the residual material adhering to the surface of the discharge mechanism 12 in time, and prevent the material from piling up on the baffle plate 124.

[0025] Working principle: In use, the raw materials to be mixed are first put into the mixing tank 3 through the feed port 11. The drive motor 62 is started, and the drive motor 62 drives the rotating column 5 to rotate, which in turn drives the rotating shaft 7 to rotate. When the rotating shaft 7 rotates, it drives the first stirring rod 91 to revolve around the rotating shaft 7. At the same time, the rotating rod 93 follows the first stirring rod 91 to revolve. Since the gear 95 at the top of the rotating rod 93 meshes with the annular tooth groove 10, the gear 95 will drive the rotating rod 93 to rotate inside the through hole 92, which in turn drives the second stirring rod 94 to rotate. With the second stirring rod 94, which is staggered with the first stirring rod 91, revolving and rotating simultaneously, the raw materials can be thoroughly mixed. When cleaning of the inner wall of the mixing tank 3 is required, tightening bolt 24 pushes push plate 19 to slide inside through groove 18, compressing second spring 22. Push plate 19 drives connecting rod 21 to extend, at which point rotating column 5 drives scraper 17 to revolve around the inner wall of mixing tank 3 via connecting rod 21, scraping and cleaning the raw materials adhering to the inner wall of mixing tank 3. After mixing is completed, rotating connecting rod 131 drives turntable 126 to rotate, causing baffle 129 to move away from below discharge chute 125, allowing the raw materials to be discharged through discharge chute 125 and discharge port 123. When the rotating shaft 7 rotates, it simultaneously drives the bottom cleaning plate 8 to rotate, cleaning the raw materials on the baffle 124 to prevent some raw materials from being unable to be discharged from the discharge chute 125. When it is necessary to clean and maintain the inside of the device, the baffle 204 can be pulled to retract into the connecting groove 203, and the mixing tank 3 can be lifted upwards to remove the mixing tank 3 as a whole for easy cleaning. During installation, the limiting block 13 is aligned with the limiting groove 202 and lowered. The limiting block 13 presses down and squeezes the inclined surface of the baffle 204, causing the baffle 204 to retract into the connecting groove 203. When the limiting block 13 moves to below the baffle 204, the third spring 206 pushes the baffle 204 out to limit the limiting block 13, thus completing the installation and fixing. It is convenient to use.
