Abstract
Description
Technical Field
[0001] This application relates to the field of granulation polishing, and in particular to a polishing apparatus for a granulator. Background Technology
[0002] Catalysts, as key materials in modern industrial production, are widely used in petrochemicals, pharmaceuticals, environmental protection, and new energy fields. In petroleum refining, catalysts are used to crack heavy oil products; in the pharmaceutical industry, they participate in the synthesis of drug intermediates; and automotive exhaust treatment relies on catalysts to convert harmful gases. Catalyst production typically involves multiple processes such as mixing, granulation, drying, and polishing, involving core equipment such as mixers, extruders, fluidized bed dryers, and rotary pot granulators. Among these, the rotary pot granulator, due to its unique rotating pot structure, enables efficient granulation and surface treatment of materials, making it a key piece of equipment in the polishing process after catalyst particle formation.
[0003] The circular pot granulator includes a vertically arranged frame and a circular pot rotatably mounted on the frame. The open end of the circular pot is angled upwards. A ventilation pipe is also installed on the frame, extending into the opening of the circular pot and supplying hot air into it. Driven by a motor, the pot rotates at a uniform speed, causing the material to roll and form granules along the pot wall under centrifugal force. During granulation, technicians introduce the relevant material into the circular pot. The rotation of the pot causes the material to roll and form granules along the pot wall under centrifugal force. Simultaneously, hot air is supplied through the ventilation pipe into the circular pot to dry and polish the granules.
[0004] Regarding the aforementioned technologies, when drying material particles, the existing ventilation pipe and the circular pot have a constant relative position. Material particles located below the air outlet have high drying efficiency, while those in areas far away have low drying efficiency. This can easily lead to significant differences in the heating of particles in different areas of the circular pot within the same time period, which can easily result in localized agglomeration and the coexistence of fine powder. Therefore, improvements are needed. Utility Model Content
[0005] To improve the problem of uneven drying of material particles by ventilation ducts, this application provides a polishing device for a granulator.
[0006] The polishing device for a granulator provided in this application adopts the following technical solution:
[0007] A polishing device for a granulator includes a machine body, a circular pot rotatably mounted on the machine body, a ventilation pipe rotatably mounted on the machine body, the ventilation pipe extending into the circular pot, the rotation axis of the ventilation pipe being aligned with the length direction of the machine body, and a rotation mechanism for adjusting the rotation of the ventilation pipe on the machine body.
[0008] The rotating mechanism includes a rotating rod rotatably mounted on the machine body, and the ventilation pipe is mounted on the rotating rod;
[0009] A movable plate is slidably mounted on the body, the sliding direction of the movable plate being consistent with the rotation axis direction of the rotating rod. The rotating rod is rotatably mounted on the movable plate. A slide rail is fixedly connected to the body, and a mounting plate is slidably mounted on the slide rail. A support column is fixedly connected to the mounting plate. An electric telescopic rod is fixedly connected to the body, and the telescopic end of the electric telescopic rod is fixedly connected to the mounting plate. The movable plate is slidably mounted on the end of the support column away from the body. An air supply component for supplying hot air to the ventilation pipe is provided on the body. A drive mechanism for driving the movable plate is provided on the body.
[0010] By adopting the above technical solution, when the material is ventilated and dried, the round pot rotates along the machine body, and the rotating mechanism drives the rotating rod to swing back and forth along the rotation axis. The ventilation pipe rotates along the width of the machine body with the rotating rod. The ventilation pipe delivers the hot air generated by the air supply component to the material in the round pot and blows the material back and forth repeatedly to dry it. This ensures that the hot air in the ventilation pipe comes into full contact with the material particles in the round pot, reduces the drying dead corners in the round pot, and improves the drying efficiency of the material.
[0011] When the amount of material inside the round pot changes, the drive mechanism moves the moving plate along the height of the support column. The moving plate then moves the rotating rod, thereby changing the height of the ventilation pipe outlet from the material inside the round pot. This allows the hot air blown out of the ventilation pipe to contact the material over a wider area, improving the drying efficiency of the material inside the round pot.
[0012] When it is necessary to adjust the angle between the round pot and the machine body, slide the moving plate to move it along the width of the machine body, so that the rotating component can move and fit in close contact with the round pot, and change the position of the ventilation pipe on the material along the width of the machine body, so that the hot air blown out by the ventilation pipe can cover the material over a wider area, thereby enhancing the drying efficiency of the material.
[0013] When it is necessary to change the position of the ventilation duct along the length of the machine body, the electric telescopic rod is activated. The electric telescopic rod drives the mounting plate to move on the slide rail. The mounting plate drives the moving plate and rotating rod to move along the length of the machine body. The position of the ventilation duct along the length of the machine body is adjusted according to the position of the material in the round pot, which improves the drying efficiency of the material.
[0014] Optionally, the rotating mechanism further includes a base slidably disposed on the rotating rod, a cam disposed on the base, and a plurality of abutting blocks fixed to the edge of the round pot. The cam and the abutting blocks are movably engaged. The rotating mechanism also includes a moving component for moving the base.
[0015] By adopting the above technical solution, before the round pot rotates, the position of the base on the rotating rod is adjusted so that the cam on the base moves and engages with the clamping block fixed on the round pot. When the round pot is started, it rotates and drives the clamping block to rotate. The clamping block contacts the side wall of the cam, causing the rotating rod to rotate along the rotation axis. When the clamping block separates from the cam, the cam moves and engages with the pot wall of the round pot under the action of gravity. The next clamping block engages with the cam again, causing the rotating rod to swing back and forth along the rotation axis. The rotating rod drives the ventilation pipe to swing back and forth inside the round pot. The moving component makes the cam and the clamping block move and engage, reducing the drying dead corners inside the round pot and allowing the ventilation pipe to fully dry the material.
[0016] Optionally, the moving assembly includes a stepper motor fixed to the end of the rotating rod away from the circular pot, a bevel gear coaxially fixed to the output end of the stepper motor, a lead screw rotatably mounted on the rotating rod, and a driven wheel fixed to the end of the lead screw near the moving plate. The bevel gear meshes with the driven wheel, and the base is threadedly connected to the lead screw.
[0017] By adopting the above technical solution, when the ventilation duct changes along the height direction or along the length direction of the machine body, the stepper motor is activated. The stepper motor drives the bevel gear to rotate, the bevel gear drives the driven wheel to rotate, the driven wheel drives the lead screw to rotate, and the lead screw drives the base to slide on the rotating rod, so that the cam on the base moves and engages with the pressing block on the round pot. This allows the rotation of the round pot to drive the ventilation duct to rotate along the rotation axis, reducing the need for manual adjustment of the ventilation duct length and improving drying efficiency.
[0018] Optionally, the drive mechanism includes an electric push rod fixed to the mounting plate, a movable plate fixed to the telescopic end of the electric push rod, and a gravity sensor disposed at the connection between the machine body and the round pot. A controller is disposed on the machine body, the gravity sensor is electrically connected to the controller, the controller is electrically connected to the electric push rod, the movable plate is slidably disposed on the support column, the movable plate is slidably disposed on the movable plate, and a limiting component for fixing the movable plate is disposed on the movable plate.
[0019] By adopting the above technical solution, when the amount of material in the round pot changes, the gravity sensor transmits a signal to the controller. The controller controls the electric push rod to rise and fall. The telescopic end of the electric push rod drives the movable plate to rise and slide on the support column. The movable plate drives the moving plate to move along the height direction of the support column. The moving plate drives the rotating rod to move along the height direction of the machine body. The limiting component can fix the moving plate on the movable plate, thereby adjusting the height of the ventilation pipe from the material in the round pot, so that the air outlet of the ventilation pipe is always above the material, reducing the need for manual replacement of the ventilation pipe and meeting the requirements of ventilation pipe for ventilating and drying materials of different amounts.
[0020] Optionally, the limiting assembly includes a limiting rod threadedly connected to the movable plate, a turntable fixed to one end of the limiting rod away from the movable plate, a stop block fixed to the other end of the limiting rod, and a limiting hole opened on the movable plate that slides and adapts to the stop block.
[0021] By adopting the above technical solution, when it is necessary to adjust the position of the moving plate on the movable plate, the moving plate is slid to adjust its position on the movable plate, so that the cam is in contact with the pot wall at the opening of the round pot. The turntable is rotated to move the limiting rod along the threaded hole on the movable rod, so that the abutment moves from the limiting hole to abut against the top wall of the moving plate, thus fixing the moving plate on the movable plate and reducing the problem of separation between the moving plate and the movable plate.
[0022] Optionally, wedge-shaped blocks are fixed to the inner walls of the two support columns, and a sliding groove is provided on the movable plate to adapt to the sliding of the wedge-shaped blocks.
[0023] By adopting the above technical solution, when the electric push rod drives the movable plate to move up and down, the sliding groove on the movable plate slides and fits against the wedge block on the support column. When the round pot rotates and drives the pressing block to rotate, the rotating rod rotates at the end of the movable plate, and the movable plate is fixed to the movable plate, reducing the phenomenon of the movable plate shifting due to the rotation of the rotating rod.
[0024] Optionally, the movable plate has a storage slot adapted to be inserted into the rotating rod, and the end of the rotating rod away from the round pot is rotatably mounted on the end of the movable plate away from the machine body. Sliding holes are provided on both side walls of the storage slot, and a sliding rod is slidably mounted within the sliding holes. Positioning plates are fixed to both ends of the sliding rod. Positioning holes are provided on the side walls of the storage slot, and pins adapted to be inserted into the positioning holes are provided on the positioning plates. The rotating rod is rotatably mounted on the sliding rod.
[0025] By adopting the above technical solution, before drying and polishing the material in the round pot, it is necessary to add powder and adhesive to the round pot. After the addition is completed, when it is necessary to dry and polish the material in the round pot, the rotating shaft is slid along the sliding hole from the end of the moving plate close to the movable plate to the end away from the movable plate. The rotating rod moves out of the storage groove on the moving plate with the rotating shaft. When the end of the rotating rod moves to the end of the moving plate away from the movable plate, the rotating rod is adjusted so that the cam abuts against the pot wall of the round pot. Then, the pin is inserted into the fixing hole to fix the rotating rod to the moving plate. When it is not necessary to dry the material, it is convenient to store the rotating rod. When filling the round pot, it reduces the obstruction of the rotating rod and ventilation pipe to the filling.
[0026] Optionally, the ventilation duct outlet is provided with a rotatable air guide plate on the duct wall.
[0027] By adopting the above technical solution, the air guide plate can adjust the air direction of the ventilation pipe, further enabling the material to come into contact with the air blown out of the ventilation pipe, thereby improving the drying effect on the material.
[0028] In summary, this application includes at least one of the following beneficial technical effects:
[0029] 1. When the position of the ventilation pipe needs to be adjusted according to the material in the round pot, the material weight changes. Under the action of the gravity sensor, the electric push rod drives the movable plate to move along the height direction, and the movable plate drives the moving plate to move along the height direction, thereby changing the height of the ventilation pipe from the material in the round pot; the electric telescopic rod pushes the mounting plate, which can change the position of the ventilation pipe along the length direction of the machine body; the sliding moving plate can change the position of the ventilation pipe along the width direction of the machine body; thus changing the position of the ventilation pipe in the round pot, satisfying the drying of materials in different areas of the round pot, and improving the drying efficiency of the materials;
[0030] 2. When the material inside the round pot needs to be dried, the screw adjuster base is positioned on the rotating rod, and the cam is in contact with the pressing block on the round pot. The rotation of the round pot drives the pressing block to rotate, and the cam drives the rotating rod to rotate along the width of the machine body. When the cam separates from the pressing block and comes into contact with the wall of the round pot, the rotating rod returns to its original position, thereby causing the ventilation pipe to swing back and forth along the width of the machine body inside the round pot, thus enhancing the drying efficiency of the ventilation pipe for the material.
[0031] 3. When drying the material in the round pot is required, the rotating rod can be slid out of the collection slot of the moving plate and fixed to the end of the moving plate away from the movable plate by a pin. When drying is not required, the rotating rod can be collected in the collection slot, reducing the impact of the rotating rod and ventilation pipe on the granulation process of the granulator.

[0038] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0039] This application discloses a polishing apparatus for a granulator. (Refer to...) Figure 1-3 The polishing device for the granulator includes a body 1, a circular pot 2 rotatably mounted on the body 1, a drying component (such as a heating plate and a fan) inside the body 1, a disc below the circular pot 2 for adjusting the angle of the pot 2, a slide rail 11 on the body 1, a mounting plate 12 adapted to the slide rail 11 sliding on the body 1, an electric telescopic rod 15 fixedly connected to the body 1, the telescopic end of the electric telescopic rod 15 fixedly connected to the mounting plate 12, a support column 3 fixedly connected to the mounting plate 12, a movable plate 4 mounted on the support column 3, and a drive mechanism for driving the movable plate 4 on the body 1. The mechanism and drive mechanism include an electric push rod 51 fixed to the body 1, a movable plate 52 fixed to the telescopic end of the electric push rod 51, a gravity sensor at the connection between the round pot 2 and the body 1, a programmable logic controller on the body 1, the gravity sensor and the controller being electrically connected, the controller and the electric push rod 51 being electrically connected, a limiting component 53 for fixing the movable plate 4 being provided on the movable plate 52, wedge blocks 31 being fixed to the inner sidewalls of the support column 3, and a sliding groove 521 adapted to the wedge blocks 31 being opened on the movable plate 52, the movable plate 4 being slidably disposed on the movable plate 52;
[0040] The limiting component 53 includes a limiting rod 532 threadedly connected to the movable plate 52. One end of the limiting rod 532 is fixedly connected to a turntable 531, and the other end of the limiting rod 532 is fixedly connected to a stop block 533. The movable plate 52 has a limiting hole 534 that is adapted to the stop block 533 for insertion. The stop block 533 is movably fitted against the top wall of the movable plate 4. A rubber anti-slip layer is fixedly or adhesively attached to the end face of the stop block 533 that contacts the movable plate 4. A ventilation pipe 13 is rotatably installed on the body 1, and the body 1 is provided with ventilation for rotation. The rotating mechanism of the pipe 13 includes a rotating rod 61 rotatably mounted on the end of the movable plate 4 away from the support column 3. The length direction of the body 1 is parallel to the direction of the opening plane of the round pot 2. The ventilation pipe 13 extends into the round pot 2 and is arranged therein. The rotation axis of the ventilation pipe 13 is parallel to the length direction of the body 1. The pipe wall of the air outlet of the ventilation pipe 13 is rotatably connected to a guide plate 14. The ventilation pipe 13 is a retractable pipe or a flexible hose. The material can be silicone glass fiber, PVC plastic, three-proof cloth, rubber aluminum foil, etc.
[0041] When the amount of material in the round pot 2 changes, the gravity sensor transmits a signal to the controller. The controller controls the electric push rod 51 to operate. When the electric push rod 51 is activated, it drives the movable plate 52 to move up and down in the height direction. The sliding groove 521 on the movable plate 52 fits into the wedge block 31 on the two support columns 3, reducing the swaying between the movable plate 52 and the support columns 3. The movable plate 52 drives the moving plate 4 to move up and down along the support columns 3. The moving plate 4 drives the rotating rod 61 to move in the height direction, so that the ventilation pipe 13 extending into the round pot 2 can automatically adjust its height according to the amount of material, so that the air outlet of the ventilation pipe 13 is always above the material.
[0042] When it is necessary to rotate the disc to adjust the angle between the round pot 2 and the machine body 1, the position of the ventilation pipe 13 in the round pot 2 along the width direction of the machine body 1 changes; the sliding plate 4 is moved along the width direction of the machine body 1 on the movable plate 52, so that the ventilation pipe 13 is above the material. Then the turntable 531 is rotated, and the turntable 531 drives the limiting rod 532 to move downward along the height direction. The limiting rod 532 drives the abutment 533 to move downward from the limiting hole 534 in the movable plate 52 until the abutment 533 abuts against the top wall of the moving plate 4. The abutment 533 fixes the moving plate 4 in the movable plate 52, reducing the shaking between the moving plate 4 and the movable plate 52.
[0043] When it is necessary to adjust the position of the ventilation pipe 13 along the length of the machine body 1 according to the amount of material in the round pot 2, the electric telescopic rod 15 is activated. The telescopic end of the electric telescopic rod 15 drives the mounting plate 12 to move on the slide rail 11, so that the moving plate 4 slides along the length of the machine body 1, thereby changing the position of the ventilation pipe 13 along the length of the machine body 1 in the round pot 2, increasing the drying area of the ventilation pipe 13 for the material in the round pot 2, and improving the drying efficiency of the material.
[0044] When the material in the round pot 2 needs to be ventilated and dried, the heating plate and fan installed in the machine body 1 are turned on to generate hot air in the ventilation pipe 13. When the round pot 2 rotates, the pot wall at the opening of the round pot 2 abuts against the rotating component. The rotating rod 61 rotates along the end of the moving plate 4 and causes the ventilation pipe 13 to swing back and forth along the rotation axis inside the round pot 2. When the material in the round pot 2 is not evenly moistened, the angle of the air guide plate 14 can be adjusted within a small range to adjust the drying range of the material, so that the material can be dried evenly and the drying effect of the material is improved.
[0045] Reference Figure 1 and Figure 4 The rotating mechanism also includes a base 62 that slides on the rotating rod 61. The base 62 has a moving groove that is adapted to the sliding of the rotating rod 61. The moving groove can be a wedge-shaped groove. A cam 63 is fixedly connected to the base 62. A pressing block 16 is fixedly connected to the pot wall at the opening of the round pot 2. The cam 63 and the pressing block 16 are movably fitted together. The circumferential side wall of the cam 63 can be concave to fit the pressing block 16 better. The rotating mechanism includes a moving component 64 for moving the base 62. The moving component 64 includes a stepper motor 641 fixedly connected to the end of the rotating rod 61 away from the round pot 2. A bevel gear 642 is coaxially fixedly connected to the output end of the stepper motor 641. A lead screw 644 is rotatably mounted on the rotating rod. A driven wheel 643 is coaxially fixedly connected to the end of the lead screw 644 away from the round pot 2. The driven wheel 643 meshes with the bevel gear 642. The base 62 is threadedly connected to the lead screw 644.
[0046] When the amount of material inside the round pot 2 changes, the electric push rod 51 drives the moving plate 4 to move along the height direction. The moving plate 4 drives the rotating rod 61 to move along the height direction, starting the stepper motor 641. The stepper motor 641 drives the bevel gear 642 to rotate, the bevel gear 642 drives the driven wheel 643 to rotate, the driven wheel 643 drives the lead screw 644 to rotate on the rotating rod 61, and the lead screw 644 drives the base 62 to rotate along the rotating rod 61, so that the cam 63 on the base 62 moves and engages with the abutment block 16 on the round pot 2, causing the rotating rod 61 to drive the ventilation pipe 13 to flow from the opening of the round pot 2 into the interior. When the cam 63 moves outward and abuts against the wall of the round pot 2, the rotating rod 61 returns to its original position, causing the ventilation pipe 13 to swing back and forth along the width of the machine body 1 inside the round pot 2, so that the hot air blown out by the ventilation pipe 13 can evenly dry the material. Since the granulation and drying and polishing process of the round pot 2 is continuous, the rotating rod 61 can be rotated in advance to separate the cam 63 from the pressing block 16, and then the position of the base 62 on the rotating rod 61 can be adjusted by the lead screw 644. If the position of the base 62 on the rotating rod 61 is adjusted when the round pot 2 is rotating, the cam 63 will easily abut against the wall of the round pot 2 and get stuck.
[0047] Reference Figure 1 and Figure 5 The movable plate 4 has a storage groove 41 that is compatible with the rotating rod 61. The end of the rotating rod 61 away from the round pot 2 is rotatably set at the end of the storage groove 41 away from the support column 3. The groove wall of the storage groove 41 has a sliding hole 42. The movable plate 4 has a sliding rod 43 that is compatible with the sliding hole 42. The two ends of the sliding rod 43 are fixedly connected to the positioning plate 44. The two ends of the movable plate 4 have positioning holes 45. The positioning plate 44 also has positioning holes 45. The positioning plate 44 has a pin 46 that is compatible with the positioning holes 45. The storage groove 41 can be evenly arranged with pulleys. The rotating rod 61 and the sliding rod 43 are rotatably connected.
[0048] When the rotating rod 61 needs to be collected, first adjust the position of the base 62 using the lead screw 644 so that the base 62 is located at the end of the rotating rod 61 away from the moving plate 4. Then rotate the rotating rod 61 to push it into the storage groove 41 of the moving plate 4. The pulley in the storage groove 41 makes it easier to store the rotating rod 61 and provides support for it. Then, align the pin 46 with the positioning hole 45 at the end of the moving plate 4 near the movable plate 52 to fix the rotating rod 61 in the storage groove 41. When the rotating rod 61 needs to be used, pull it out of the storage groove 41 and insert the pin 46 on the positioning plate 44 into the positioning hole 45 at the end of the moving plate 4 away from the movable plate 52, so that the rotating rod 61 is fixed at the end of the moving plate 4 away from the movable plate 52. This reduces the impact of the rotating rod 61 and the ventilation pipe 13 on the granulation process of the granulator and makes it easier to store the rotating rod 61 and the ventilation pipe 13.
[0049] The implementation principle of a polishing device for a granulator according to an embodiment of this application is as follows: When the amount of material in the round pot 2 changes, the gravity sensor transmits a signal to the controller, which controls the electric push rod 51. The electric push rod 51 causes the movable plate 52 to change its position along the height direction, thereby adjusting the height of the ventilation pipe 13. The electric telescopic rod 15 pushes the mounting plate 12, which can adjust the position of the ventilation pipe 13 along the length direction of the machine body 1, so that the ventilation pipe 13 can cover more area inside the round pot 2. The position of the moving plate 4 on the movable plate 52 is adjusted, and the moving plate 4 is fixed by the limiting rod 532, which can adjust the position of the ventilation pipe 13 along the width direction of the machine body 1. When the round pot 2 rotates, the position of the base 62 on the rotating rod 61 is adjusted so that the cam 63 moves and engages with the pressing block 16. When the cam 63 abuts against the pressing block 16, the rotating rod 61... Moving outwards along the opening of the circular pot 2, when the cam 63 abuts against the pot wall of the circular pot 2, the rotating rod 61 returns to its original position. The cam 63 drives the rotating rod 61 to rotate back and forth along the width direction of the machine body 1, causing the ventilation pipe 13 to swing back and forth inside the circular pot 2, thereby enabling the ventilation pipe 13 to dry the material evenly. When the ventilation pipe 13 is not needed, the rotating rod 61 can be collected in the collection trough 41, reducing the impact of the rotating rod 61 and the ventilation pipe 13 on the granulation process of the granulator. This device, through the installation plate 12, the moving plate 4, the rotating rod 61 and other mechanisms, allows the position of the ventilation pipe 13 to be adjusted according to the material condition inside the circular pot 2, and makes full use of the potential energy of the rotating circular pot 2 to drive the rotating rod 61 to rotate, enhancing the drying effect of the ventilation pipe on the material and reducing the occurrence of local agglomeration and fine powder during the drying and polishing process of the material.
[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
