Description

Technical Field

[0001] The present invention relates to the technical field of drying equipment, and specifically relates to a sealed chemical raw material drying device. Background Art

[0002] There are many types of chemical raw materials with a wide range of uses. There are as many as 5 to 7 million kinds of chemicals in the world, and more than 100,000 kinds are sold and circulated in the market. Moreover, more than 1,000 new chemicals are introduced every year. Before storing chemical raw materials, it is necessary to dry the raw materials to avoid the moisture in the raw materials affecting the storage of chemical raw materials.

[0003] For the drying treatment of chemical raw materials, the existing authorized publication number CN116147292B proposes a chemical raw material drying device. The device includes a drying cylinder. The top of the drying cylinder is fixedly connected with a feed pipe, and the bottom end of the feed pipe is communicated with the inside of the drying cylinder. An air inlet pipe is fixedly connected to the drying cylinder. The device uses hot air to blow the chemical materials and uses the flowing hot air to remove the moisture of the materials, thereby realizing the drying treatment of the chemical materials.

[0004] Although the above device can realize the drying of chemical raw materials, by using the method of hot air blowing, the drying of the materials is gradually heated from the surface layer of the materials to the inside. This method requires the materials to be heated for a long time when drying the materials. Therefore, the drying treatment of the materials needs to last for a long time, and the drying efficiency is relatively low. In view of the above problems, we provide a sealed chemical raw material drying device to solve the problems mentioned above. Summary of the Invention

[0041] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0043] Microwave generators 5 are provided on both sides inside the drying barrel 2. A vacuum pumping assembly 8 for evacuating the drying barrel 2 is provided at the upper end inside the chassis 1. A storage bin 9 is provided on one side of the chassis 1. A shaft bracket 15 is provided at the port of the drying barrel 2. A drive shaft 13 is rotatably connected between the inner end face of the drying barrel 2 and the shaft bracket 15. First rotating frames 14 are fixedly connected to both ends of the drive shaft 13. A plurality of uniformly distributed material trays 16 are provided between the two first rotating frames 14. Side plates 17 are fixedly connected to both sides of the material tray 16. Connecting end shafts 18 are fixedly connected to the upper ends of the side plates 17. The connecting end shafts 18 are rotatably connected to the first rotating frames 14. Action blocks 19 are fixedly connected to the connecting end shafts 18 on the side away from the sealing cover 10. A feeding mechanism 6 for spreading the materials in the storage bin 9 onto the material trays 16 is provided at the upper end of the chassis 1. A drive mechanism 7 for driving the drive shaft 13 to rotate is provided on one side of the drying barrel 2. A discharging mechanism 3 is provided at the lower end of the drying barrel 2. A discharging mechanism 4 for turning over and discharging the material trays 16 is provided at the lower position on one side of the drying barrel 2. An electric control cabinet 12 is further provided on the chassis 1. During operation, the feeding mechanism 6 sends the materials in the storage bin 9 to the material trays 16 and evenly spreads the materials onto the material trays 16. Then the drive mechanism 7 drives the drive shaft 13 to rotate, so that the material trays 16 run one by one under the feeding mechanism 6 to receive the materials. After the materials are received, the drive assembly drives the drive shaft 13 to rotate at a uniform low speed. At the same time, the microwave generators 5 are started to perform microwave drying on the materials. At the same time, the vacuum pumping assembly 8 pumps out the air and the generated moisture in the drying barrel 2, so that the inside of the drying barrel 2 is in a negative pressure state, thereby improving the drying efficiency. After drying, the discharging mechanism 4 turns over the bottom material trays 16 one by one, and then the discharging mechanism 3 discharges the materials, realizing the drying process of the materials.

[0044] The vacuum pumping assembly 8 includes a vacuum pump 803, which is installed at one side of the upper end face of the chassis 1. The suction end of the vacuum pump 803 is connected with a suction pipe 801, and the suction pipe 801 is communicated with the drying barrel 2. The exhaust port of the vacuum pump 803 is installed with an exhaust pipe 802, and the upper port of the exhaust pipe 802 penetrates through the upper end plate of the chassis 1. During operation, the vacuum pump 803 is started, and the air and water vapor in the drying barrel 2 are pumped out through the suction pipe 801, so that the inside of the drying barrel 2 is in a negative pressure state. At this time, the boiling point of water decreases, and the moisture can evaporate and vaporize faster, thereby effectively improving the drying efficiency of the material.

[0045] The material spreading mechanism 6 includes a triangular cover 607, which is fixedly connected to the upper end of the chassis 1. The lower end of the triangular cover 607 is fixedly connected with a strip-shaped feed pipe 608, and the lower end of the strip-shaped feed pipe 608 penetrates into the drying barrel 2. A closing assembly 61 for blocking the strip-shaped feed pipe 608 is arranged inside the triangular cover 607. The closing assembly 61 includes a second electric cylinder 611, and the second electric cylinder 611 is respectively fixedly connected to both sides of the upper end of the vertical plate of the triangular cover 607. A strip-shaped sealing strip 612 for closing the strip-shaped feed pipe 608 is fixedly connected between the output ends of the second electric cylinders 611. The second electric cylinder 611 and the strip-shaped sealing strip 612 can be used to open or close the strip-shaped feed pipe 608 during use. When the material in the drying barrel 2 is dried, the second electric cylinder 611 drives the strip-shaped sealing strip 612 to move to close the strip-shaped feed pipe 608, so that the drying barrel 2 can be in a sealed state, which is convenient for the vacuum pumping assembly 8 to pump the inside of the drying barrel 2 to a negative pressure state. When it is necessary to convey materials to the material tray 16, the second electric cylinder 611 drives the strip-shaped sealing strip 612 to move upward to open the strip-shaped feed pipe 608, facilitating the passage of materials.

[0046] Two limiting rods 604 are fixedly connected to the position of the chassis 1 above the storage bin 9. A moving bar 602 is slidably connected between the two limiting rods 604. A lifting pipe 601 is fixedly connected to the moving bar 602. A second screw rod 610 is rotatably connected in the lifting pipe 601. Feeding openings are formed on both sides of the lower end of the lifting pipe 601. A second driving motor 605 for driving the second screw rod 610 to rotate is provided on the lifting pipe 601. A threaded rod 603 is also rotatably connected to the position of the chassis 1 between the two limiting rods 604. The threaded rod 603 is threadedly connected to the moving bar 602. A second servo motor 609 for driving the threaded rod 603 to rotate is provided at one end of the chassis 1. A swinging assembly 62 for driving the material tray 16 to swing is provided on the drying barrel 2. An avoidance opening for avoiding the second driving motor 605 is further provided at the upper end of the chassis 1; when feeding materials to the material tray 16, the second driving motor 605 is started to drive the second screw rod 610 to rotate. The second screw rod 610 rotates to pump the materials in the storage bin 9 to the guide pipe 606 and discharge them along the guide pipe 606 to the strip-shaped feeding pipe 608, and enter the material tray 16 from the strip-shaped feeding pipe 608. At the same time, the second servo motor 609 drives the threaded rod 603 to rotate. The threaded rod 603 rotates to drive the moving bar 602, and the moving bar 602 drives the lifting pipe 601 to move horizontally, so as to release the materials along the material tray 16. At the same time, the swinging assembly 62 performs a small-amplitude and rapid swing on the material tray 16 to disperse the materials falling into the material tray 16 to both sides, so that the materials are spread out on the material tray 16 to prevent material accumulation.

[0047] The swing assembly 62 includes a first synchronous pulley 621, which is installed at one end of the threaded rod 603. A second synchronous belt 623 is rotatably connected to the side of the drying barrel 2 away from the sealing cover 10. A synchronous belt 622 is installed between the first synchronous pulley 621 and the second synchronous belt 623.

One end of the connecting rod 629 away from the second synchronous belt 623 is connected to a swing rod 628. A second rotating frame 624 is fixedly connected to the upper end of the side of the drying barrel 2 away from the sealing cover 10. An internal hexagonal rotating cylinder 627 is rotatably connected inside the second rotating frame 624. The upper end of the swing rod 628 is fixedly connected to the internal hexagonal rotating cylinder 627. A hexagonal slider 631 is slidably connected inside the internal hexagonal rotating cylinder 627. A connecting optical shaft 630 is fixedly connected to the hexagonal slider 631. A second sealing connection sleeve 625 is provided at the position of the drying barrel 2 matching the internal hexagonal rotating cylinder 627. The connecting optical shaft 630 passes through the second sealing connection sleeve 625. A second U-shaped connection block 626 is fixedly connected to the end of the connecting optical shaft 630. A third electric cylinder 632 for pushing the hexagonal slider 631 is further provided inside the internal hexagonal rotating cylinder 627. During operation, first, the third electric cylinder 632 is used to push the hexagonal slider 631 to move the connecting optical shaft 630. The movement of the connecting optical shaft 630 drives the second U-shaped connection block 626 to move, so that the second U-shaped connection block 626 is sleeved on the action block 19. Then, when the threaded rod 603 rotates, it will drive the first synchronous pulley 621 to rotate. The rotation of the first synchronous pulley 621 drives the synchronous belt 622. The rotation of the synchronous belt 622 drives the second synchronous belt 623. The rotation of the second synchronous belt 623 drives the connecting rod 629 to move. The connecting rod 629 drives the swing rod 628 to perform a fast and small-amplitude swing. The swing rod 628 drives the internal hexagonal rotating cylinder 627 and transmits the swing to the second U-shaped connection block 626, thereby driving the material tray 16 to perform corresponding movements to spread the materials out.

[0048] The driving mechanism 7 includes a first servo motor 702, which is installed at one end of the drying barrel 2 away from the sealing cover 10 by a motor bracket. A second gear 703 is installed at the output end of the first servo motor 702. A first gear 701 is installed at the end of the driving shaft 13 away from the sealing cover 10. The second gear 703 meshes with the first gear 701. During operation, when the first servo motor 702 is started, it can drive the second gear 703 to rotate. The rotation of the second gear 703 drives the first gear 701 to rotate. The rotation of the first gear 701 can drive the driving shaft 13 to perform corresponding rotation.

[0049] The discharging mechanism 3 includes a discharging cover 301 which is fixedly connected to the lower end of the drying barrel 2. The discharging cover 301 is communicated with the drying barrel 2. A communicating pipe 303 is connected to the lower end of the discharging cover 301. A closing valve 304 is provided on the communicating pipe 303. The lower end of the communicating pipe 303 is connected to a discharging pipe 305. A first screw rod 306 is rotatably connected inside the discharging pipe 305. A first driving motor 302 for driving the first screw rod 306 is installed at one end of the discharging pipe 305 close to the communicating pipe 303. During discharging, the closing valve 304 is opened, and at the same time, the first driving motor 302 is started to drive the first screw rod 306 to rotate. The rotation of the first screw rod 306 can send the material out from the port of the discharging pipe 305, thereby realizing discharging.

[0050] The unloading mechanism 4 includes an installation box 401 which is installed at the lower end of the drying barrel 2 on the side away from the sealing cover 10. A sliding rod 406 is fixedly connected inside the installation box 401. A sliding block 407 is slidably connected to the sliding rod 406. A servo steering gear 405 is installed on the sliding block 407. The output end of the servo steering gear 405 is connected to a turning optical axis 404 which is inserted into a first sealing connection sleeve 403. The first sealing connection sleeve 403 is installed at the lower end on one side of the drying barrel 2. A first U-shaped connection block 402 is installed at the end of the turning optical axis 404 away from the servo steering gear 405. A first electric cylinder 408 for pushing the sliding block 407 to move is also provided inside the installation box 401. The openings of both the first U-shaped connection block 402 and the second U-shaped connection block 626 are in a horn shape. When it is necessary to turn over the material tray 16, the first electric cylinder 408 drives the servo steering gear 405 to move towards the drying barrel 2. At the same time, the turning optical axis 404 drives the first U-shaped connection block 402 to move, and the first U-shaped connection block 402 is sleeved on the action block 19. Then the servo steering gear 405 drives the turning optical axis 404 to rotate. The rotation of the turning optical axis 404 drives the first U-shaped connection block 402 to rotate. The rotation of the first U-shaped connection block 402 drives the action block 19, and the action block 19 drives the corresponding material tray 16 to turn over, realizing the unloading operation.

[0051] The working principle of the present invention is as follows: During operation, first pour the chemical raw materials to be dried into the storage bin 9. Then, the second drive motor 605 starts to drive the second screw rod 610 to rotate. The rotation of the second screw rod 610 pumps the materials in the storage bin 9 to the guide pipe 606 and discharges them along the guide pipe 606 into the strip-shaped feed pipe 608. The materials enter the material tray 16 from the strip-shaped feed pipe 608. At the same time, the second servo motor 609 drives the threaded rod 603 to rotate. The rotation of the threaded rod 603 drives the moving strip 602, and the moving strip 602 drives the lifting pipe 601 to move horizontally, so that the materials can be released along the material tray 16. At the same time, the swinging assembly 62 makes a small and rapid swing of the material tray 16, dispersing the materials falling into the material tray 16 to both sides, so that the materials are spread out on the material tray 16. When the material tray 16 is fully loaded, the drive mechanism 7 drives the drive shaft 13 to rotate, rotating the next material tray 16 under the strip-shaped feed pipe 608, and then repeating the above steps. After each material tray 16 is fully filled in this way, the closing assembly 61 closes the strip-shaped feed pipe 608, and at the same time the closing valve 304 is closed. Then, the microwave generator 5 and the vacuum pumping assembly 8 are started to perform microwave drying on the materials. At the same time, the vacuum pumping assembly 8 pumps out the air and the generated moisture in the drying barrel 2. When the materials are dried, the closing valve 304 is opened, and the first electric cylinder 408 drives the servo steering gear 405 to move towards the drying barrel 2. At this time, the turning optical axis 404 drives the first U-shaped connecting block 402 to move, sleeving the first U-shaped connecting block 402 on the action block 19. Then, the servo steering gear 405 drives the turning optical axis 404 to rotate. The rotation of the turning optical axis 404 drives the first U-shaped connecting block 402 to rotate. The rotation of the first U-shaped connecting block 402 drives the action block 19, and the action block 19 drives the corresponding material tray 16 to turn over, realizing the unloading operation. After the unloading is completed, the servo steering gear 405 resets, and then the first electric cylinder 408 resets to separate the first U-shaped connecting block 402 from the current action block 19. Then, the drive mechanism 7 drives the drive shaft 13 to rotate, rotating the next material tray 16 to the unloading position, and then repeating the above steps to unload each material tray 16 one by one. The unloaded materials enter the discharge pipe 305 from the discharge cover 301. At the same time, the first drive motor 302 starts to drive the first screw rod 306 to rotate. The rotation of the first screw rod 306 can send the materials out from the port of the discharge pipe 305, thus realizing discharging.
