Description

Technical Field

[0001] This invention relates to the field of drying equipment technology, specifically a single-cone dryer with a stirrer. Background Technology

[0002] A single cone dryer is a drying device driven by the natural flow of materials. The device consists of a motor, frame, hollow ribbon agitator, jacket, and discharge valve. The material is rotated and heated in the cone, falling from the top to form a thin layer, and then rising again from the bottom. This cycle continues until the material is completely dried.

[0003] However, during installation, single-cone dryers are typically secured to four mounting seats on the outer wall of the drying cylinder using four lifting rings. After the drying cylinder is hoisted onto the mounting frame, operators must remove each lifting ring from the mounting seat sequentially, a cumbersome process. Furthermore, if the mounting holes on the mounting seat are not aligned with those on the mounting frame after the drying cylinder is positioned on the mounting frame, it is difficult to observe whether the mounting holes are perfectly aligned when adjusting the drying cylinder due to the high position of the mounting frame and mounting seat, resulting in poor operational flexibility. Additionally, after the drying cylinder is adjusted, multiple bolts are needed to lock the mounting seat and mounting frame together before installing the drying cylinder, leading to slow installation efficiency.

Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 13As shown, the single-cone dryer with a stirrer according to the present invention includes a mounting frame 1, a fixing ring 11 mounted above the mounting frame 1, a drying cylinder 2 fixedly connected to the fixing ring 11, a mounting structure 4 disposed above the mounting frame 1, a barrel cover 10 mounted above the drying cylinder 2, a stirring structure 3 disposed in the barrel cover 10, a positioning structure 6 disposed between the mounting frame 1 and the fixing ring 11, a lifting structure 7 disposed on the drying cylinder 2, and a heat-conducting structure 9 disposed between the drying cylinder 2 and the barrel cover 10; the stirring structure 3 includes a mounting shaft 301 rotatably connected to the middle of the barrel cover 10 and a plurality of connecting rods 302 fixedly connected to the outer wall of the mounting shaft 301. The end of the connecting rod 302 is fixedly connected to a spiral plate 303; the mounting structure 4 includes a slip ring 401 slidably connected to the mounting frame 1 and a mounting ring 402 fixedly connected above the slip ring 401. Multiple stops 403 are slidably connected inside the mounting ring 402. The stops 403 are trapezoidal in shape. A first spring 409 is fixedly connected between the stops 403 and the mounting ring 402. A fixing block 404 is fixedly connected to the bottom of the stops 403. The fixing ring 11 is provided with a fixing groove 405 that cooperates with the fixing block 404. A first lead screw 408 is rotatably connected to the mounting frame 1. The slip ring 401 is threadedly connected to the first lead screw 408.

[0024] Specifically, such as Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, two connecting blocks 304 are fixedly connected above the mounting shaft 301. A connecting post 306 is fixedly connected to each connecting block 304. The connecting post 306 is rotatably connected to the lid 10. A mounting base 305 is fixedly connected above the lid 10. The connecting post 306 is rotatably connected to the mounting base 305. A first motor 307 is mounted on the mounting base 305. The connecting post 306 is fixed to the output shaft of the first motor 307. The heat-conducting structure 9 includes a first connecting pipe 901 fixedly connected to the bottom of the drying cylinder 2 and a first cavity 902 located inside the drying cylinder 2. A second connecting pipe 903 is fixedly connected to the drying cylinder 2. A second cavity 906 is provided inside the lid 10. A connecting post 304 is fixedly connected above the lid 10. A third connecting pipe 905 is connected, and a pipe 904 is installed between the second connecting pipe 903 and the third connecting pipe 905. A fourth connecting pipe 907 is fixedly connected to the barrel cover 10. The bottom of the drying cylinder 2 is provided with a feeding structure 8. The feeding structure 8 includes a shell 801 installed at the bottom of the drying cylinder 2 and two fixed columns 802 rotatably connected to the shell 801. A sealing plate 803 is fixedly connected between the two fixed columns 802 and rotatably connected to the shell 801. An mounting plate 804 is fixedly connected to the shell 801, and a second motor 805 is mounted on the mounting plate 804. The second motor 805 is fixedly connected to one of the fixed columns 802. When it is necessary to dry the material... First, the material is added into the drying cylinder 2. Then, the heat medium is conveyed to the first connecting pipe 901 through the external conveying pipe. From the first connecting pipe 901, it enters the first cavity 902 inside the drying cylinder 2. After the first cavity 902 is filled with heat medium, it enters the pipe 904 through the second connecting pipe 903, and then enters the second cavity 906 inside the lid 10 through the pipe 904 and the third connecting pipe 905. Finally, the heat medium is output from the fourth connecting pipe 907. The heat medium heats the drying cylinder 2 and the lid 10, thereby drying the material. At the same time, the first motor 307 can be started. When the output shaft of the first motor 307 rotates, it drives the connecting column 306 to rotate. When the connecting column 306 rotates, it drives the mounting shaft 301 to rotate through the connecting block 304. 301 drives the spiral plate 303 to rotate via the connecting rod 302. The rotation of the connecting rod 302 stirs the material, and simultaneously, the spiral plate 303 lifts and rotates the material, causing continuous tumbling and improving drying efficiency. Meanwhile, the heating medium enters the hollow part of the mounting shaft 301. Both the connecting rod 302 and the spiral plate 303 are hollow. The connecting rod 302 connects the spiral plate 303 to the mounting shaft 301, allowing the heating medium to enter the spiral plate 303 from the connecting rod 302, heating both the connecting rod 302 and the spiral plate 303, resulting in better drying. After drying, the heating medium can be replaced with a cooling medium to cool the material for unloading, reducing cooling time.By starting the second motor 805, the output shaft of the second motor 805 rotates, causing the fixed column 802 to rotate. The rotation of the fixed column 802 then causes the sealing plate 803 to rotate. When the fixed column 802 rotates 90 degrees, the sealing plate 803 stops sealing the bottom of the drying cylinder 2, allowing the material to slide down from the bottom of the drying cylinder 2 for unloading.

[0025] Specifically, such as Figure 4 , Figure 7 and Figure 12As shown, a guide rod 407 is fixedly connected inside the mounting bracket 1, and the slip ring 401 is slidably connected to the guide rod 407. The positioning structure 6 includes a sliding sleeve 601 fixedly connected to the mounting bracket 1 and a positioning rod 602 slidably connected to the sliding sleeve 601. The fixed ring 11 is provided with a positioning groove 603, and the positioning rod 602 engages with the positioning groove 603. A mounting block 604 is fixedly connected to the bottom of the positioning rod 602, and a tension spring 608 is fixedly connected between the mounting block 604 and the sliding sleeve 601. A mounting post 606 is rotatably connected inside the fixed ring 11, and a roller 607 is fixedly connected to the mounting post 606. The roller 607 rolls with the mounting bracket 1, and a ball bearing is slidably connected to the top of the positioning rod 602. 605, the ball bearing 605 rolls in cooperation with the mounting frame 1. When hoisting the drying cylinder 2, the hoisting rope is located within the four connecting seats 701, cooperating with the connecting plate 703 to hoist the drying cylinder 2. After the drying cylinder 2 is hoisted above the mounting frame 1, it descends, causing the fixing ring 11 to abut against the inclined surfaces of the multiple stops 403. This causes the stops 403 to retract into the mounting ring 402. As the stops 403 slide into the mounting ring 402, the first spring 409 contracts. Simultaneously, when the top surface of the fixing ring 11 is lower than the bottom surface of the stops 403, the stops 403 extend under the action of the first spring 409. The extension of the multiple stops 403 abuts the fixing ring 11, facilitating the quick installation of the drying cylinder 2 onto the mounting frame 1 and improving the efficiency of the drying cylinder 2. Installation efficiency is improved. When the positioning groove 603 at the bottom of the fixing ring 11 is not aligned with the positioning rod 602, the fixing ring 11 will press down on the positioning rod 602. The positioning rod 602 will then drive the mounting block 604 downwards. As the mounting block 604 moves downwards, the tension spring 608 extends. At this time, the operator can rotate the drying cylinder 2, causing the drying cylinder 2 to rotate, which in turn causes the fixing ring 11 and the mounting frame 1 to rotate. The fixing ring 11 will then drive the roller 607 to roll against the mounting frame 1. The roller 607 converts sliding friction into rolling friction, making the rotation of the drying cylinder 2 easier. Simultaneously, the ball bearing 605 on the positioning rod 602 rolls with the fixing ring 11, reducing the friction of the positioning rod 602. When the positioning groove 603 moves to align with the positioning rod 602, the positioning rod... 602 will move upward under the action of tension spring 608 and engage with positioning groove 603. At this time, the handwheel at the bottom of the first lead screw 408 can be rotated to rotate the first lead screw 408. When the first lead screw 408 rotates, the thread drives the slip ring 401 to slide downward. When the slip ring 401 slides, it moves more smoothly through the guide rod 407. At the same time, the slip ring 401 drives the mounting ring 402 to move downward. When the mounting ring 402 moves downward, it drives the stop block 403 to abut against the fixing ring 11, and at the same time drives the fixing block 404 to engage with the fixing groove 405. Meanwhile, the engagement of positioning rod 602 with positioning groove 603 can play a positioning role, so that fixing block 404 is aligned with fixing groove 405, improving the flexibility of operation. At the same time, fixing block 404 and positioning rod 602 are engaged with fixing ring 11.This design facilitates the securing of the fixing ring 11, preventing the drying cylinder 2 from rotating during internal stirring and improving the stability of the fixing ring 11 and the mounting frame 1.

[0026] Specifically, such as Figure 1 , Figure 3 , Figure 7 , Figure 8 and Figure 9 As shown, the stop block 403 is driven by a drive structure 5. The drive structure 5 includes a drive ring 501 rotatably connected to the mounting ring 402 and a plurality of drive grooves 502 provided on the drive ring 501. A connecting shaft 406 is rotatably connected to the stop block 403. Each connecting shaft 406 rolls with a corresponding drive groove 502. A slide rod 503 is fixedly connected to the bottom of the drive ring 501. The slide rod 503 is slidably connected to the mounting bracket 1. A second lead screw 504 is threadedly connected to the slide rod 503. The second lead screw 504 is threadedly connected to the drive ring 501. The top end of the second lead screw 504 abuts against the mounting ring 402. When it is necessary to disassemble the fixing ring 11, simply move the fixing block 404 upward until it no longer abuts against the mounting ring 402. The fixing groove 405 engages, and then the sliding rod 503 drives the drive ring 501 to rotate. When the drive ring 501 rotates, multiple connecting shafts 406 roll and cooperate in multiple drive grooves 502, so that multiple connecting shafts 406 drive multiple stops 403 to retract into the mounting ring 402 at the same time. Then, the handwheel at the bottom of the second lead screw 504 rotates the second lead screw 504. When the second lead screw 504 rotates, it engages with the sliding rod 503 and the drive ring 501 threadedly, so that the second lead screw 504 moves upward until it abuts against the mounting ring 402, fixing the drive ring 501. At this time, the drying cylinder 2 can be disassembled. The drive ring 501 drives multiple stops 403 to retract into the mounting ring 402 at the same time. When disassembling the drying cylinder 2, it is convenient to quickly cooperate with the hoisting equipment for hoisting and disassembly.

[0027] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 10 and Figure 11As shown, the hoisting structure 7 includes four connecting seats 701 fixedly connected to the outer wall of the drying cylinder 2 and a rotating shaft 702 rotatably connected to the connecting seats 701. A connecting plate 703 is fixedly connected to the rotating shaft 702, and the connecting plate 703 is rotatably connected to the connecting seat 701. A torsion spring 704 is fixedly connected between the rotating shaft 702 and the connecting seat 701. A limiting block 705 is slidably connected inside the connecting seat 701. A limiting groove 706 is provided on the rotating shaft 702, and the limiting block 705 and the limiting groove are connected... 706 engages. A pull rope 707 is fixedly connected to the bottom of the limiting block 705. A connecting ring 710 is fixedly connected to the other end of the pull rope 707. A second spring 708 is fixedly connected between the limiting block 705 and the connecting seat 701. A guide post 709 is fixedly connected to the connecting ring 710. The guide post 709 is slidably connected to the connecting seat 701. A fixing rod 711 is fixedly connected to the bottom of the connecting ring 710. A pressing plate 712 is fixedly connected to the bottom of the fixing rod 711. The drying cylinder 2 is hoisted... After being mounted on the mounting bracket 1, pressing the pressing plate 712 causes the fixing rod 711 to move downwards. The fixing rod 711 then moves the connecting ring 710 downwards. This downward movement of the connecting ring 710 causes the guide post 709 to slide against the connecting seat 701. The guide post 709 ensures smoother movement of the connecting ring 710. Simultaneously, the connecting ring 710 causes the pull rope 707 to move downwards. The pull rope 707 then causes the limiting block 705 to slide downwards, which in turn causes the second spring 7... 08 retracts, and at the same time, the limiting block 705 causes the limiting block 705 to no longer engage with the limiting groove 706. At this time, the rotating shaft 702 will rotate under the action of the torsion spring 704. The rotating shaft 702 drives the connecting plate 703 to rotate, so that the connecting plate 703 no longer seals the connecting seat 701. At this time, the lifting rope can move upward. The connecting plate 703 will not cause obstruction. When it moves downward through the connecting ring 710, the four connecting plates 703 will rotate, so that the lifting rope can easily slide down from the connecting seat 701, making the operation more convenient.

[0028] In use, when drying materials is required, the material is first added to the drying cylinder 2. Then, the heat medium is conveyed to the first connecting pipe 901 through the external conveying pipe, and enters the first cavity 902 inside the drying cylinder 2 from the first connecting pipe 901. After the first cavity 902 is filled with heat medium, it enters the pipe 904 from the second connecting pipe 903, and then enters the second cavity 906 inside the lid 10 from the pipe 904 and the third connecting pipe 905. Finally, the heat medium is output from the fourth connecting pipe 907. The heat medium heats the drying cylinder 2 and the lid 10, thereby drying the material. At the same time, the first motor 307 can be started. When the output shaft of the first motor 307 rotates, it drives the connecting column 306 to rotate. When the connecting column 306 rotates, it drives the mounting shaft 301 to rotate through the connecting block 304. The mounting shaft 301 drives the spiral plate 303 to rotate through the connecting rod 302. When the connecting rod 302 rotates, it stirs the material, and at the same time, it works with the spiral plate 303. 03 The material is rotated and lifted, causing it to tumble continuously, which improves drying efficiency. At the same time, the heat medium enters the hollow part of the mounting shaft 301. Both the connecting rod 302 and the spiral plate 303 are hollow. The connecting rod 302 connects the spiral plate 303 to the mounting shaft 301, allowing the heat medium to enter the spiral plate 303 from the connecting rod 302, heating both the connecting rod 302 and the spiral plate 303, resulting in better drying of the material. After the material is dried, the heat medium can be replaced with a cold medium to cool the material for unloading, reducing the cooling time. When unloading is required, the second motor 805 is started. When the output shaft of the second motor 805 rotates, it drives the fixed column 802 to rotate. When the fixed column 802 rotates, it drives the sealing plate 803 to rotate. When the fixed column 802 rotates 90 degrees, the sealing plate 803 stops sealing the bottom of the drying cylinder 2. At this time, the material will slide down from the bottom of the drying cylinder 2 for unloading. When hoisting the drying cylinder 2, the hoisting rope is located within the four connecting seats 701, cooperating with the connecting plate 703 to hoist the drying cylinder 2. After the drying cylinder 2 is hoisted above the mounting frame 1, the drying cylinder 2 descends, causing the fixing ring 11 to abut against the inclined surfaces of multiple stops 403, causing the stops 403 to retract into the mounting ring 402. As the stops 403 slide into the mounting ring 402, the first spring 409 contracts. Simultaneously, when the top surface of the fixing ring 11 is lower than the bottom surface of the stops 403, the stops 403 extend under the action of the first spring 409. The extension of multiple stops 403 then supports the fixing ring 11. The fixed ring 11 provides a stop, facilitating the quick installation of the drying cylinder 2 onto the mounting frame 1, thus improving the installation efficiency of the drying cylinder 2. Simultaneously, when the positioning groove 603 at the bottom of the fixed ring 11 is not aligned with the positioning rod 602, the fixed ring 11 will press down on the positioning rod 602. The positioning rod 602 will then drive the mounting block 604 downwards. As the mounting block 604 moves downwards, the tension spring 608 extends. At this time, the operator can rotate the drying cylinder 2, causing the drying cylinder 2 to rotate, which in turn causes the fixed ring 11 and the mounting frame 1 to rotate. The fixed ring 11 will then drive the roller 607 to roll and engage with the mounting frame 1. Through the design of the roller 607… This converts sliding friction into rolling friction, making the rotation of the drying cylinder 2 easier. Simultaneously, the ball bearing 605 on the positioning rod 602 rolls against the fixing ring 11, reducing the friction of the positioning rod 602. When the positioning groove 603 moves to align with the positioning rod 602, the positioning rod 602 moves upward under the action of the tension spring 608 and engages with the positioning groove 603. At this point, the handwheel at the bottom of the first lead screw 408 can be rotated to rotate the first lead screw 408. When the first lead screw 408 rotates, the thread drives the slip ring 401 to slide downward. As the slip ring 401 slides, it moves more smoothly through the guide rod 407. The sliding ring 401 drives the mounting ring 402 to move downward. When the mounting ring 402 moves downward, it drives the stop block 403 to press against the fixed ring 11, and at the same time drives the fixed block 404 to engage with the fixed groove 405. Meanwhile, the engagement of the positioning rod 602 with the positioning groove 603 can play a positioning role, so that the fixed block 404 is aligned with the fixed groove 405, which improves the operational flexibility. At the same time, the engagement of the fixed block 404 and the positioning rod 602 with the fixed ring 11 makes it easy to fix the fixed ring 11, avoids the drying cylinder 2 from rotating during internal stirring, and improves the stability of the fixed ring 11 and the mounting frame 1. When it is necessary to disassemble the fixing ring 11, simply move the fixing block 404 upward until it is no longer engaged with the fixing groove 405, and then drive the drive ring 501 to rotate through the slide rod 503. When the drive ring 501 rotates, multiple connecting shafts 406 roll and engage in multiple drive grooves 502, causing multiple connecting shafts 406 to drive multiple stops 403 to retract into the mounting ring 402 simultaneously. Then, the second lead screw 504 is rotated by the handwheel at the bottom of the second lead screw 504. When the second lead screw 504 rotates, it engages with the slide rod 503 and the drive ring 501 threadedly, causing the second lead screw 504 to move upward until it abuts against the mounting ring 402, thus fixing the drive ring 501. At this time, the drying cylinder 2 can be disassembled. By driving multiple stops 403 to retract into the mounting ring 402 simultaneously through the drive ring 501, it is easy to quickly coordinate with the hoisting equipment for hoisting and disassembly when disassembling the drying cylinder 2. After the drying cylinder 2 is hoisted onto the mounting frame 1, pressing the pressing plate 712 causes the fixing rod 711 to move downwards. The fixing rod 711 then moves the connecting ring 710 downwards. This downward movement of the connecting ring 710 causes the guide post 709 to slide against the connecting seat 701. The guide post 709 ensures smoother movement of the connecting ring 710. Simultaneously, the connecting ring 710 causes the pull rope 707 to move downwards. The pull rope 707 then causes the limiting block 705 to slide downwards, which in turn causes the second... When spring 708 contracts, the limiting block 705 stops engaging with the limiting groove 706. At this time, the rotating shaft 702 rotates under the action of torsion spring 704. The rotating shaft 702 drives the connecting plate 703 to rotate, so that the connecting plate 703 no longer seals the connecting seat 701. At this time, the lifting rope can move upward without the connecting plate 703 causing obstruction. When the connecting ring 710 moves downward, the four connecting plates 703 rotate, allowing the lifting rope to slide easily from the connecting seat 701, making the operation more convenient.
