Description

[0002] Single cone dryer is a drying equipment driven by the natural flow of materials. It is composed of 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 at the bottom, and this cycle is repeated until the material is completely dry.

[0003] However, when installing a single-cone dryer, it is usually fastened to four mounting seats on the outer wall of the drying cylinder by four lifting rings. After the drying cylinder is hoisted onto the mounting frame, the operator is required to remove each lifting ring from the mounting seat in turn, which is cumbersome. Moreover, after the mounting seat of the drying cylinder is located on the mounting frame, if the mounting holes on the mounting seat are not aligned with the mounting holes on the mounting frame, when adjusting the drying cylinder, it is inconvenient to observe whether the mounting holes are completely aligned due to the high positions of the mounting frame and the mounting seat, and the operational flexibility is poor.

[0039] Specifically, 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, and a connecting column 306 is fixedly connected to the connecting block 304, and the connecting column 306 is rotatably connected to the barrel cover 10, and a mounting seat 305 is fixedly connected above the barrel cover 10, and the connecting column 306 is rotatably connected to the mounting seat 305, and a first motor 307 is installed on the mounting seat 305, and the connecting column 306 is fixed to the output shaft of the first motor 307, and 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 provided in the drying cylinder 2, and a second connecting pipe 903 is fixedly connected to the drying cylinder 2, and a second cavity 906 is provided in the barrel cover 10, and a connecting pipe 903 is fixedly connected to the barrel cover 10 above. A third connecting pipe 905 is connected, 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, and a material discharge structure 8 is provided at the bottom of the drying cylinder 2, and the material discharge 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 the sealing plate 803 is rotatably connected to the shell 801, a mounting plate 804 is fixedly connected to the shell 801, and a second motor 805 is installed on the mounting plate 804, and the second motor 805 is fixedly connected to one of the fixed columns 802. When the material needs to be dried, First, the material is added into the drying cylinder 2, and then the heat medium is transported to the first connecting pipe 901 through the external conveying pipe, and enters the first cavity 902 in the drying cylinder 2 from the first connecting pipe 901. After the heat medium fills the first cavity 902, it will enter the pipe 904 from the second connecting pipe 903, and then enter the second cavity 906 in the barrel cover 10 from the pipe 904 and the third connecting pipe 905. Finally, the heat medium will be output from the fourth connecting pipe 907. The heat medium heats the drying cylinder 2 and the barrel cover 10, and then dries the material. At the same time, the first motor 307 can be started. When the output shaft of the first motor 307 rotates, it will drive the connecting column 306 to rotate. When the connecting column 306 rotates, it will drive the installation shaft 301 to rotate through the connecting block 304. The installation shaft 301 will drive the spiral plate 303 to rotate through the connecting rod 302. When the connecting rod 302 rotates, the material is stirred, and the spiral plate 303 is cooperated to rotate and lift the material, so that the material is constantly turned over, thereby improving the drying efficiency. At the same time, the heat medium will enter the hollow part of the installation shaft 301, and the connecting rod 302 and the spiral plate 303 are both hollow. The connecting rod 302 connects the spiral plate 303 with the installation shaft 301, so that the heat medium will enter the spiral plate 303 from the connecting rod 302, and the connecting rod 302 and the spiral plate 303 are also heated, so that the drying effect of the material is better. At the same time, when the material is dried, the heat medium can be replaced by a cold medium to cool the material so that the material can be unloaded, which reduces the cooling time of the material. When unloading is required,By starting the second motor 805, the output shaft of the second motor 805 rotates to drive the fixed column 802 to rotate, and the fixed column 802 rotates to drive the sealing plate 803 to rotate. When the fixed column 802 rotates 90 degrees, the sealing plate 803 no longer seals the bottom of the drying cylinder 2. At this time, the material will slide from the bottom of the drying cylinder 2 and be unloaded.

[0040] Specifically, Figure 4 , Figure 7 and Fig.12As shown, a guide rod 407 is fixedly connected in the mounting frame 1, 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 frame 1 and a positioning rod 602 slidably connected in the sliding sleeve 601, a positioning groove 603 is provided on the fixed ring 11, the positioning rod 602 is engaged with the positioning groove 603, a mounting block 604 is fixedly connected to the bottom of the positioning rod 602, a tension spring 608 is fixedly connected between the mounting block 604 and the sliding sleeve 601, a mounting column 606 is rotatably connected in the fixed ring 11, a roller 607 is fixedly connected to the mounting column 606, the roller 607 is rollingly matched with the mounting frame 1, and a ball bearing is rollingly connected to the top of the positioning rod 602 605, the ball 605 and the fixing ring 11 are rollingly matched. When the drying cylinder 2 is hoisted, the hoisting rope will be located in the four connecting seats 701, and cooperate with the connecting plate 703 to hoist the drying cylinder 2. When the drying cylinder 2 is hoisted above the mounting frame 1, the drying cylinder 2 is lowered, so that the fixing ring 11 contacts the inclined surfaces of the multiple blocks 403, so that the blocks 403 are contracted into the mounting ring 402. When the blocks 403 slide into the mounting ring 402, the first spring 409 contracts. At the same time, when the top surface of the fixing ring 11 is lower than the bottom surface of the blocks 403, the blocks 403 extend out under the action of the first spring 409, and the multiple blocks 403 extend out to block the fixing ring 11, so that the drying cylinder 2 can be quickly installed on the mounting frame 1, thereby improving the drying cylinder 2. 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 the positioning rod 602 downward, and the positioning rod 602 will drive the mounting block 604 to move downward. When the mounting block 604 moves downward, the tension spring 608 will extend. At this time, the operator can rotate the drying drum 2 to make the drying drum 2 drive the fixing ring 11 and the mounting frame 1 to rotate. The fixing ring 11 will drive the roller 607 to roll with the mounting frame 1. The setting of the roller 607 converts the sliding friction into rolling friction, making the rotation of the drying drum 2 easier. At the same time, the ball 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 The rod 602 will move upward under the action of the tension spring 608 and engage with the positioning groove 603. At this time, the handwheel at the bottom of the first screw rod 408 can be rotated to rotate the first screw rod 408. When the first screw rod 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 installation ring 402 to move downward. When the installation ring 402 moves downward, it drives the stopper 403 to press against the fixing ring 11, and drives the fixing block 404 to engage with the fixing groove 405. At the same time, the engagement of the positioning rod 602 with the positioning groove 603 can play a positioning role, so that the fixing block 404 is aligned with the fixing groove 405, which improves the operational flexibility. At the same time, the fixing block 404 and the positioning rod 602 are engaged with the fixing ring 11.It is convenient to fix the fixing ring 11, avoid the drying drum 2 from rotating during internal stirring, and improve the stability of the fixing ring 11 and the mounting frame 1.

[0041] Specifically, Figure 1 , Figure 3 , Figure 7 , Figure 8 and Fig. 9 As shown, the stopper 403 is driven by a driving structure 5, and the driving structure 5 includes a driving ring 501 rotatably connected to the mounting ring 402 and a plurality of driving grooves 502 provided on the driving ring 501, and a connecting shaft 406 is rotatably connected to the stopper 403, and each of the connecting shafts 406 rolls with the corresponding driving groove 502, and a sliding rod 503 is fixedly connected to the bottom of the driving ring 501, and the sliding rod 503 is slidably connected to the mounting frame 1, and a second screw rod 504 is internally threadedly connected to the sliding rod 503, and the second screw rod 504 is threadedly connected to the driving ring 501, and the top of the second screw rod 504 conflicts with the mounting ring 402. When the fixing ring 11 needs to be disassembled, it is only necessary to move the fixing block 404 upward until it is no longer in contact with the fixing ring 11. The fixing groove 405 is engaged, and then the driving ring 501 is driven to rotate through the sliding rod 503. When the driving ring 501 rotates, the multiple connecting shafts 406 roll and cooperate in the multiple driving grooves 502, so that the multiple connecting shafts 406 drive the multiple blocks 403 to shrink into the mounting ring 402 at the same time. Then the second screw rod 504 is rotated by the handwheel at the bottom end of the second screw rod 504. When the second screw rod 504 rotates, it cooperates with the sliding rod 503 and the driving ring 501 threads, so that the second screw rod 504 moves upward until it conflicts with the mounting ring 402, thereby fixing the driving ring 501. At this time, the drying cylinder 2 can be disassembled, and the multiple blocks 403 are driven to shrink into the mounting ring 402 at the same time through the driving ring 501. When the drying cylinder 2 is disassembled, it is convenient to quickly cooperate with the lifting equipment for lifting and disassembly.

[0042] Specifically, Figure 1 , Figure 2 , Figure 3 , Fig.10 and Fig.11As shown, the hanging structure 7 includes four connecting seats 701 fixedly connected to the outer wall of the drying drum 2 and a rotating shaft 702 rotatably connected to the connecting seat 701, a connecting plate 703 is fixedly connected to the rotating shaft 702, 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 limited block 705 is slidably connected in the connecting seat 701, a limiting groove 706 is provided on the rotating shaft 702, and the limiting block 705 and the limiting groove 706 is engaged, a pull rope 707 is fixedly connected to the bottom of the limit block 705, and the other end of the pull rope 707 is fixedly connected to a connecting ring 710, a second spring 708 is fixedly connected between the limit block 705 and the connecting seat 701, a guide column 709 is fixedly connected to the connecting ring 710, and the guide column 709 is slidably connected to the connecting seat 701, a fixing rod 711 is fixedly connected to the bottom of the connecting ring 710, and a pressing plate 712 is fixedly connected to the bottom of the fixing rod 711, and the drying drum 2 is hoisted. After being mounted on the mounting frame 1, the pressing plate 712 can be pressed. When the pressing plate 712 moves downward, it drives the fixing rod 711 to move. When the fixing rod 711 moves, it drives the connecting ring 710 to move downward. When the connecting ring 710 moves downward, it drives the guide column 709 and the connecting seat 701 to slide. The setting of the guide column 709 makes the connecting ring 710 move more smoothly. At the same time, the connecting ring 710 drives the pull rope 707 to move downward. When the pull rope 707 moves, it drives the limit block 705 to slide downward. The limit block 705 makes the second spring 7 08 contracts, and at the same time, the limit block 705 drives the limit block 705 to no longer engage with the limit groove 706. At this time, the rotating shaft 702 will rotate under the action of the torsion spring 704, and 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, and the connecting plate 703 will not cause any obstruction. When moving downward through the connecting ring 710, the four connecting plates 703 rotate, so that the lifting rope can easily slide out of the connecting seat 701, making the operation more convenient.

[0043] When the present invention is in use, when it is necessary to dry the material, the material is first added to the drying cylinder 2, and then the heat medium is transported to the first connecting pipe 901 through the external conveying pipe, and enters the first cavity 902 in the drying cylinder 2 from the first connecting pipe 901. After the heat medium fills the first cavity 902, it will enter the pipeline 904 from the second connecting pipe 903, and then enter the second cavity 906 in the barrel cover 10 from the pipeline 904 and the third connecting pipe 905. Finally, the heat medium will be output from the fourth connecting pipe 907, and the heat medium heats the drying cylinder 2 and the barrel cover 10, thereby drying the material. At the same time, the first motor 307 can be started, and the output shaft of the first motor 307 will drive the connecting column 306 to rotate when the output shaft rotates. When the connecting column 306 rotates, it will drive the installation shaft 301 to rotate through the connecting block 304, and the installation shaft 301 will drive the spiral plate 303 to rotate through the connecting rod 302. When the connecting rod 302 rotates, the material is stirred, and at the same time, the spiral plate 303 is cooperated with the spiral plate 303 to rotate. 03 rotates and lifts the material, so that the material is constantly turned over, which improves the drying efficiency. At the same time, the heat medium will enter the hollow part of the installation shaft 301, and the connecting rod 302 and the spiral plate 303 are both hollow. The connecting rod 302 connects the spiral plate 303 with the installation shaft 301, so that the heat medium will enter the spiral plate 303 from the connecting rod 302, and the connecting rod 302 and the spiral plate 303 are also heated, so that the drying effect of the material is better. At the same time, when the material is dried, the heat medium can be replaced by a cold medium to cool the material so that the material can be unloaded, which reduces the cooling time of the material. When unloading is required, by starting the second motor 805, the output shaft of the second motor 805 rotates to drive the fixed column 802 to rotate, and the fixed column 802 rotates to drive the sealing plate 803 to rotate. When the fixed column 802 rotates ninety degrees, it drives the sealing plate 803 to no longer seal the bottom of the drying cylinder 2. At this time, the material will slide from the bottom of the drying cylinder 2 for unloading;

[0044] When the drying drum 2 is hoisted, the hoisting rope will be located in the four connecting seats 701, and cooperate with the connecting plate 703 to hoist the drying drum 2. When the drying drum 2 is hoisted above the mounting frame 1, the drying drum 2 is lowered, so that the fixing ring 11 contacts the inclined surfaces of the multiple blocks 403, so that the blocks 403 are retracted into the mounting ring 402. When the blocks 403 slide into the mounting ring 402, the first spring 409 contracts. At the same time, when the top surface of the fixing ring 11 is lower than the bottom surface of the blocks 403, the blocks 403 are extended under the action of the first spring 409. The fixed ring 11 is used for blocking, so that the drying cylinder 2 can be quickly installed on the mounting frame 1, thereby improving the installation efficiency of the drying cylinder 2. At the same time, 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 the positioning rod 602 downward, and the positioning rod 602 will drive the mounting block 604 to move downward. When the mounting block 604 moves downward, the tension spring 608 extends. At this time, the operator can rotate the drying cylinder 2 to make the drying cylinder 2 drive the fixed ring 11 and the mounting frame 1 to rotate, and the fixed ring 11 will drive the roller 607 to roll with the mounting frame 1. The arrangement converts the sliding friction into rolling friction, making the rotation of the drying drum 2 easier. At the same time, the ball 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 moves upward under the action of the tension spring 608 and engages with the positioning groove 603. At this time, the hand wheel at the bottom of the first screw rod 408 can be rotated to rotate the first screw rod 408. When the first screw rod 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. The sliding ring 401 drives the mounting ring 402 to move downward, and the mounting ring 402 drives the stopper 403 to press against the fixing ring 11 when moving downward, and drives the fixing block 404 to engage with the fixing groove 405, and the positioning rod 602 is engaged with the positioning groove 603 to play a positioning role, so that the fixing block 404 is aligned with the fixing groove 405, which improves the operational flexibility. At the same time, the fixing block 404 and the positioning rod 602 are engaged with the fixing ring 11, which is convenient for fixing the fixing ring 11, avoiding the rotation of the drying drum 2 during internal stirring, and improving the stability of the fixing ring 11 and the mounting frame 1;

[0045] When the fixing ring 11 needs to be disassembled, it is only necessary to move the fixing block 404 upward until it is no longer engaged with the fixing groove 405, and then drive the driving ring 501 to rotate through the sliding rod 503. When the driving ring 501 rotates, the multiple connecting shafts 406 roll and cooperate in the multiple driving grooves 502, so that the multiple connecting shafts 406 drive the multiple stoppers 403 to shrink into the mounting ring 402 at the same time, and then the second screw rod 504 is rotated by the hand wheel at the bottom end of the second screw rod 504. When the second screw rod 504 rotates, it cooperates with the sliding rod 503 and the driving ring 501 threads, so that the second screw rod 504 moves upward until it conflicts with the mounting ring 402, fixing the driving ring 501. At this time, the drying cylinder 2 can be disassembled, and the multiple stoppers 403 are driven to shrink into the mounting ring 402 at the same time by the driving ring 501. When the drying cylinder 2 is disassembled, it is convenient to quickly cooperate with the lifting equipment for lifting and disassembly;

[0046] After the drying drum 2 is hoisted onto the mounting frame 1, the pressing plate 712 can be pressed, and the pressing plate 712 can drive the fixing rod 711 to move when it moves downward. When the fixing rod 711 moves, it drives the connecting ring 710 to move downward. When the connecting ring 710 moves downward, it drives the guide column 709 and the connecting seat 701 to slide. The setting of the guide column 709 makes the connecting ring 710 move more smoothly. At the same time, the connecting ring 710 drives the pull rope 707 to move downward. When the pull rope 707 moves, it drives the limit block 705 to slide downward. The limit block 705 makes the second When the spring 708 contracts, the limit block 705 drives the limit block 705 to no longer engage with the limit groove 706. At this time, the rotating shaft 702 will rotate under the action of the torsion spring 704, and 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, and the connecting plate 703 will not cause any obstruction. When the connecting ring 710 moves downward, the four connecting plates 703 rotate, so that the lifting rope can easily slide out of the connecting seat 701, making the operation more convenient.
