Description

Technical Field

[0001] The invention relates to the technical field of vacuum dryers, in particular to a spherical vacuum dryer. Background Art

[0002] Vacuum dryer is a kind of equipment that dries under negative pressure. The boiling point of the material solvent is lowered under vacuum state, so it is suitable for drying unstable or heat-sensitive materials. The vacuum dryer has good sealing performance, so it is also suitable for drying materials that need to recover solvents and contain strong irritating and toxic gases. Vacuum drying is to place the dried material under vacuum conditions for heating and drying. It uses a vacuum pump to evacuate air and moisture, so that the studio is in a vacuum state, which greatly accelerates the drying rate of the material and also saves energy. Spherical vacuum dryer is a common vacuum dryer.

[0003] However, when the traditional spherical vacuum dryer is temporarily installed, it is fastened to the supporting feet by bolts. Some spherical dryers are large in size, and it is troublesome to temporarily install the spherical dryer by bolting. It is also inconvenient to disassemble the spherical dryer, and the installation and disassembly efficiency of the dryer is low. A scraper is provided inside the spherical dryer to stir the material. Due to the special shape of the spherical dryer, it is inconvenient to replace the internal scraper when the scraper is irreversibly worn and cannot be used. When the material is drying, the separated water vapor easily adheres to the observation window, which affects the operator's observation of the drying state of the material inside the dryer, and it is inconvenient to make corresponding drying adjustments based on the observation results, which affects the drying effect of the material.

The connecting plate 608 and the scraper 607 are respectively plugged into the two sockets 701. The interior of each sleeve shaft 606 is symmetrically and slidably connected with two blocks 703 with trapezoidal cross-sections. The blocks 703 are engaged with the through groove 702. The blocks 703 are slidably connected with the mounting shaft 605. A third spring 705 is fixedly connected between the blocks 703 and the sleeve shaft 606.

[0043] When the present invention is in use, first, when the dryer body 1 needs to be installed, the lifting rope can be passed around the installation slot 309 at the lower end of the four lifting blocks 308. When the dryer body 1 is installed by the lifting equipment, the lifting rope will first drive the lifting block 308 to rise, and the lifting block 308 rises to resist the clamping strip 304, the clamping strip 304 slides, and the first spring 307 contracts. At this time, the dryer body 1 can continue to be lifted, and the slot 302 on the mounting seat 301 is aligned with the supporting foot 303. When the mounting seat 301 is fully inserted into the supporting foot 303, after the lifting rope is removed, the first spring 307 is reset to drive the clamping strip 304 to reset, and the clamping strip 304 is then engaged with the clamping slot 305 on the supporting foot 303, thereby fixing the dryer body 1 on the supporting foot 303.

Qualitatively, the setting of the slider 310 and the slide groove 311 improves the sliding stability between the lifting block 308 and the mounting seat 301. The suction and pressure pipe 203 on the dryer body 1 is connected to the cooler. When the dryer body 1 is used, materials are added to the inside of the dryer body 1 through the feeding structure 4, and then the negative pressure device on the cooler is started to extract the air inside the dryer body 1 through the suction and pressure pipe 203. At the same time, the reading of the pressure gauge 204 is observed to keep the inside of the dryer body 1 in a vacuum state. When drying the material, the valve of the steam inlet and outlet pipe 202 is opened, and the hot steam enters the hollow interlayer inside the dryer body 1 from a steam inlet and outlet pipe 202, heats the inner wall of the dryer body 1, and is discharged from another steam inlet and outlet pipe 202. At this time, the material contacts the inner wall of the dryer body 1, and the inner wall is heated to dry the material, and the dried material is discharged from the discharge pipe 201;

[0044] Then, when it is necessary to add materials to the inside of the dryer body 1, the hand wheel 413 can be turned, and the rotation of the hand wheel 413 drives the screw 412 to rotate. The screw 412 and the threaded sleeve 411 are threadedly rotated and then lifted, so that the limit ring 414 no longer conflicts with the mounting block 415. At this time, the threaded sleeve 411 and the screw 412 can be rotated around the connecting shaft 410, and the screw 412 slides out from the pressing port 416 on the mounting block 415. After multiple screws 412 slide out, the sealing cover 402 can be rotated, and the sealing cover 402 drives the connecting block 408 to rotate around the rotating shaft 407. The sealing ring 405 is separated from the sealing groove 404. At this time, the sealing cover 402 is opened, and then materials are added to the interior of the dryer body 1. After the addition is completed, the sealing cover 402 is closed, and the screw 412 is rotated to the pressing port 416, and the hand wheel 413 is rotated to lock the sealing cover 402 through the limit ring 414. The setting of the sealing ring 405 and the sealing groove 404 improves the sealing performance, so that the vacuum effect inside the dryer body 1 is better. When the dryer body 1 is drying the material, the moisture in the material is separated from the material, and the moisture evaporates and meets the transparent cover 403 and condenses and adheres to the transparent cover 403 The operation staff can observe the drying state of the material inside the dryer body 1 by hooking the hook block 511 with two fingers at this time, and then push the push bar 510 with the palm, the push bar 510 slides to drive the limit rod 505 to slide, the second spring 509 is compressed, and the limit rod 505 is no longer engaged with the limit groove 506 on the sealing cover 402, and the rotating sleeve 502 can be rotated at this time, the rotating sleeve 502 rotates to drive the connecting bar 503 to rotate, the connecting bar 503 rotates to drive the cleaning bar 504 to rotate, and the cleaning bar 504 then wipes the water drops on the transparent cover 403, and after wiping, the operation staff can observe the drying state of the material inside the dryer body 1 by hooking the hook block 511 with two fingers at this time, and then push the push bar 510 with the palm, the push bar 510 slides to drive the limit rod 505 to slide, the second spring 509 is compressed, and the limit rod 505 is no longer engaged with the limit groove 506 on the sealing cover 402, and the rotating sleeve 502 can be rotated at this time, the rotating sleeve 502 rotates to drive the connecting bar 503 to rotate, and the connecting bar 503 rotates to drive the cleaning bar 504 to rotate, and the cleaning bar 504 then wipes the water drops on the transparent cover 403, and after wiping, the operation staff can observe the drying state of the material inside the dryer body 1 by hooking the hook block 511 with two fingers, and then push the push bar 510 with the palm, the push bar 510 slides to drive the limit rod 505 to slide, the second spring 509 is compressed, and the limit rod 505 is no longer engaged with the limit groove 506 on the sealing cover 402, and the second spring 509 is compressed, and The drying state of the material inside the dryer body 1 can be observed, and corresponding operations can be made according to the state of the material, thereby improving the drying effect of the material. After the transparent cover 403 is cleaned, the hand holding the rotating sleeve 502 is released, and the resistance of the push bar 510 disappears. The second spring 509 is reset to drive the limit rod 505 to engage in any other limit groove 506. The setting of the guide rod 508 improves the sliding stability of the limit rod 505 and prevents the second spring 509 from running off. The setting of the first sealing sleeve 501 and the second sealing sleeve 507 improves the sealing inside the dryer body 1.

[0045] Finally, when the material is dried inside the dryer body 1, the motor 603 on the support plate 602 is started, and the motor 603 drives the installation shaft 605 to rotate, and the rotation of the installation shaft 605 drives the sleeve shaft 606 to rotate, and the rotation of the sleeve shaft 606 drives the scraper 607 and the connecting plate 608 to rotate, thereby stirring the material inside the dryer body 1 and improving the material drying effect. The setting of the third sealing sleeve 604 improves the sealing performance of the dryer body 1. When the scraper 607 is worn and needs to be replaced, the feed pipe can be opened. The sealing cover 402 on 401 is then pressed, and the two pressing rods 707 on the installation shaft 605 are pressed, and the pressing rods 707 drive the slide bar 706 to slide, and the slide bar 706 drives the block 703 to slide, and the third spring 705 is compressed, and the block 703 no longer engages with the through groove 702 on the scraper 607 and the connecting plate 608. At this time, the connecting plate 608 can be pulled out from the socket 701 on the sleeve shaft 606, and the connecting plate 608 is rotatably connected to the scraper 607 through the fixed shaft 609. After the connecting plate 608 is pulled out, The scraper 607 can be pulled out. After the scraper 607 and the connecting plate 608 are not fixed to the sleeve 606, they can be taken out from the feed pipe 401 and then replaced. After replacement, the scraper 607 and the connecting plate 608 are placed inside the dryer body 1, and then the scraper 607 and the connecting plate 608 are plugged into the socket 701 on the sleeve 606 in turn. Since the cross section of the block 703 is a trapezoid, when the scraper 607 and the connecting plate 608 first contact the block 703, the block 703 first retreats into the dryer body 1. Inside the sleeve shaft 606, the third spring 705 is compressed. When the scraper 607 and the connecting plate 608 are fully inserted into the socket 701, the third spring 705 is reset and drives the block 703 to engage the through grooves 702 on the scraper 607 and the connecting plate 608, thereby fixing the scraper 607 and the connecting plate 608. The setting of the connecting plate 608 improves the stability of the scraper 607 during stirring, and the setting of the guide strip 704 improves the sliding stability of the block 703 and avoids the deviation of the third spring 705.
