Description

Technical Field

[0001] This application relates to the field of granulator technology, and in particular to a disc granulator for preparing moisture-retaining ceramsite. Background Technology

[0002] In recent years, with the gradual standardization and institutionalization of air pollution control by the state, thermal power plants have made significant progress in dust removal, desulfurization, and denitrification technologies. In order to promote the comprehensive utilization and sustainable development of fly ash, it is urgent to develop a method for the large-scale, efficient, and high-value utilization of fly ash in conjunction with current social development.

[0003] The main component of moisture-retaining ceramsite is fly ash, mixed with appropriate proportions of binders, additives, and nutrients. It is manufactured through processes such as batching, mixing, and granulation. The disc granulator is an important piece of equipment for the preparation of moisture-retaining ceramsite. It includes a frame, a plate, an adjustment device, a disc, and a scraper. During use, the deflection angle of the plate is adjusted by the adjustment device, which in turn adjusts the tilt angle of the disc. Then, the disc is driven to rotate. At the same time, powdery material is added into the disc. Under the friction between the material and the disc, the material is carried upward by the disc. When the material rises to a certain height, it rolls downward under its own weight, gradually forming spherical particles. Finally, the spherical particles are discharged outward, thus achieving the purpose of granulation.

[0004] However, existing disc granulators still have some defects in use: the scraper is the key to achieving efficient and continuous granulation in order to clean the sticky areas of the disc. However, in actual use, in order to prevent the formation of "cleaning blind spots" inside the disc, the scraper is generally long. However, the distance from different positions of the scraper to the center of rotation is different, and its linear velocity is also different. As a result, the linear velocity of the outer end of the scraper is much higher than that of the inner end, and the friction and impact with the material are more intense. This causes the outer side of the scraper to wear much faster than the inner side. With long-term use, it is easy to cause the cleaning effect of the scraper to deteriorate, and it is also easy to cause the scraper to deform or even break due to fatigue. Summary of the Invention

[0005] This application proposes a disc granulator for preparing moisture-retaining ceramsite, which has the advantage of effectively setting multiple scrapers on the main plate and using the outer and inner plates for effective fixation, so that each scraper can be responsible for cleaning a ring-shaped area inside the disc, thereby solving the problems of uncontrollable scraper length and poor cleaning effect in existing models.

[0006] To achieve the above objectives, this application adopts the following technical solution: a disc granulator for preparing moisture-retaining ceramsite, comprising:

[0007] The disc and the limiting component are arranged inside the disc and include a main board. Several scrapers are arranged inside the main board. Outer plates are respectively provided at the lower two ends of the main board and are movably engaged with the outermost scraper. Several inner plates are provided in the lower middle part of the main board, and one inner plate is movably engaged between two adjacent scrapers. By changing the scraper from a single ultra-long design to a multi-segment splicing design, the length of the scraper is controllable, thereby reducing the overall linear speed difference of a single scraper and reducing the wear difference of a single scraper, thus reducing the possibility of deformation or even breakage of a single scraper.

[0008] Furthermore, the scraper includes:

[0009] The scraper body has an upper half that is internally engaged with the main board, and one side of the lower half of the scraper body is arc-shaped while the other side of the lower half of the scraper body is vertical.

[0010] The connecting body has a threaded groove at the top of the scraper body and a thread on the lower half of the connecting body. The scraper body is threadedly connected to the lower half of the connecting body through the threaded groove, and the upper half of the connecting body is movably engaged with the top of the main board.

[0011] Furthermore, the disk is tilted, and the placement of the limiting component forms a 45-degree angle with the radius direction of the disk. The disk rotates clockwise, and the limiting component is located in the upper half of the disk, on the side facing the direction of rotation of the disk.

[0012] The outer plate is U-shaped and the inner plate is I-shaped. The inner walls of the outer plate and the inner plate are respectively engaged with the side wall of the scraper body.

[0013] The motherboard, outer board, and inner board are all fixedly connected to the two side walls with locking pins. The locking pins on the motherboard and the outer board are fixedly connected by locking plates, and the locking pins on the motherboard and the inner board are fixedly connected by locking plates.

[0014] Furthermore, the limiting component is a constituent part of the connecting mechanism, and the connecting mechanism is disposed on the upper half of the disk. The connecting mechanism further includes:

[0015] The connecting plate, wherein the limiting component is movably mounted on the connecting plate;

[0016] The connecting frame has two ends of the connecting plate that are movably connected to one end of a connecting frame by bolts.

[0017] Furthermore, the disk is a component of the working mechanism, and the working mechanism is mounted on a fixed mechanism, which includes:

[0018] A fixed frame, wherein the fixed frame is set on the ground;

[0019] The fixed machine plate is mounted on the top of the fixed machine frame, and the two ends of the fixed machine frame are movably hinged to the two ends of the fixed machine plate, respectively. The other end of the connecting frame is fixedly connected to the side wall of the fixed machine plate.

[0020] The adjustment device is fixedly connected to the bottom end of the fixed frame, and the top end of the adjustment device abuts against the bottom end of the fixed plate.

[0021] Furthermore, the working mechanism also includes:

[0022] The rotating component has its rear end fixedly connected to one end of the rotating component, and its other end movably connected to the front end of the fixed plate.

[0023] The power component has its rear end fixedly connected to the top end of the fixed plate, and the rotating component is provided with a gear, with the front end of the power component meshing with the gear of the rotating component.

[0024] Furthermore, the limiting component also includes:

[0025] A deflector is used to connect the main board and the connecting board;

[0026] A movable component is provided between the two outer panels.

[0027] Furthermore, the deflector includes:

[0028] A deflection plate is movably engaged with a connecting plate, and the deflection plate is movably connected to the connecting plate by bolts.

[0029] The deflection post is fixedly connected to the top end of the deflection plate, and the bottom end of the deflection post is threadedly connected to the top end of the main board.

[0030] Furthermore, the movable component includes:

[0031] The movable body has two ends that are respectively movably connected to the interior of two outer plates. The end of the movable body is close to the vertical wall of the scraper body. The length of the movable body is longer than the distance of the main plate, and the movable body can rotate around the arc-shaped wall of the scraper body. The distance between the bottom surface of the scraper body and the top surface of the disc is the thickness of the movable body.

[0032] A rotary motor is provided, with a circular cavity inside each of the two outer plates, and a rotary motor is placed inside the circular cavity of one outer plate. The rotary motor can rotate in both directions, and one end of the movable body is movably connected to the rotary motor.

[0033] A rotating block, with the other end of the rotating motor fixedly connected to the rotating block;

[0034] A rotating ring is fixedly fitted inside the circular cavity of another outer plate, and the rotating ring and the rotating block are concentrically arranged, and the rotating block and the rotating ring have the same magnetism.

[0035] Furthermore, the limiting component also includes:

[0036] The cleaning component has an arc groove on one side wall of both the outer and inner plates, and the arc groove is close to the arc-shaped wall of the scraper body. The top end of the arc groove is fixedly connected to the top end of the cleaning component, and the top and bottom ends of the cleaning component are connected by a spring.

[0037] The cleaning holes are provided on both the outer and inner plates above the arc groove. The bottom of the cleaning hole is connected to the top of the cleaning component. The cleaning hole consists of vertical holes and oblique holes, and several oblique holes are connected to one vertical hole. The oblique holes are designed to be biased towards the scraper body, and a filter screen is provided at the end of the oblique holes.

[0038] By creating arc grooves in the outer and inner plates, when the moving part is not in use, it can be rotated to a horizontal position and remain in the arc groove. When the moving part reciprocates, it can rotate along the bottom of the scraper to clean the material attached to the scraper, and it can also tap the outer and inner plates to further vibrate the material attached to the scraper, thus achieving effective cleaning of the scraper.

[0039] By setting cleaning components in the arc grooves of the outer and inner plates, and opening cleaning holes on both the outer and inner plates above the cleaning components, when the moving part rotates into the arc groove, the moving part effectively squeezes the cleaning components, causing the gas inside the cleaning components to be discharged to the side wall of the scraper through the cleaning holes, thereby achieving further cleaning of the scraper.

[0040] The beneficial effects of this invention are as follows:

[0041] This application provides a disc granulator for preparing moisture-retaining ceramsite. By arranging multiple scrapers inside a main plate, and limiting and fixing both ends of the scrapers by an outer or inner plate, the stability of the scraper arrangement is effectively ensured. This transforms the scraper design from a single extra-long design to a multi-segment splicing design, making the scraper length controllable. This reduces the overall linear velocity difference of individual scrapers, minimizes the wear difference between individual scrapers, and reduces the possibility of individual scrapers deforming or even breaking due to external impact during use. At the same time, it facilitates replacement when individual scrapers are damaged, thus reducing costs.

[0042] By setting movable parts on two outer plates, and these movable parts can rotate, and the lower half of the scraper is arc-shaped, when multiple scrapers are installed on the main plate, rotating the movable parts to a vertical position allows for horizontal adjustment of the multiple scrapers, ensuring that the bottom height of the multiple scrapers is consistent, thereby improving the ease of scraper installation. When the scrapers have been used for a long time, rotating the movable parts to a vertical position allows for direct detection of the distance between the top surface of the disc and the bottom surface of the scraper, promptly identifying whether the scraper is severely worn. If the scraper is severely worn, it needs to be replaced, thereby improving the ease of scraper inspection. Attached Figure Description

[0057] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0058] Example 1: A disc granulator for preparing moisture-retaining ceramsite, including a fixing mechanism 1, such as... Figures 1-2 The fixing mechanism 1 includes a fixing frame 11, a fixing plate 12, and an adjusting device 13. The fixing plate 12 is mounted on the top of the fixing frame 11, and the two ends of the fixing frame 11 are movably hinged to the two ends of the fixing plate 12. The bottom end of the fixing frame 11 is fixedly connected to the bottom end of the adjusting device 13, and the top end of the adjusting device 13 abuts against the bottom end of the fixing plate 12. The tilt angle of the fixing plate 12 can be effectively adjusted by the adjusting device 13, thereby changing the tilt angle of the fixing plate 12 to adjust the particle size of the material.

[0059] like Figures 1-3The fixed mechanism 1 is equipped with a working mechanism 2 for rotation to achieve granulation. The working mechanism 2 includes a disc 21, a rotating component 22, and a power component 23. The rear end of the disc 21 is fixedly connected to one end of the rotating component 22, and the other end of the rotating component 22 is movably connected to the front end of the fixed plate 12 to enhance the stability of the disc 21 and the rotating component 22. The rear end of the power component 23 is fixedly connected to the top end of the fixed plate 12. The rotating component 22 is equipped with a gear, and the front end of the power component 23 meshes with the gear of the rotating component 22. When the power component 23 is started, it can drive the rotating component 22 to rotate, thereby driving the disc 21 to rotate slowly. At the same time, the powdery material in the disc 21 is sprayed with water multiple times, and under the action of the rotation of the disc 21, it gradually forms spherical particles to achieve the purpose of granulation.

[0060] like Figures 1-4 The fixing mechanism 1 is also provided with a connecting mechanism 3, which is located on the upper half of the disc 21. This helps the limiting component 4 to fully clean the material adhering to the working mechanism 2 and provides assistance for the material to fall and form. The connecting mechanism 3 includes a connecting frame 31, a connecting plate 32, and a limiting component 4. The limiting component 4 is movably mounted on the connecting plate 32. Both ends of the connecting plate 32 are movably connected to one end of a connecting frame 31 by bolts, and the other end of the connecting frame 31 is fixedly connected to the side wall of the fixing plate 12. The connecting frame 31 and the connecting plate 32 effectively and stably mount the limiting component 4 in the disc 21.

[0061] like Figures 3-7 The disc 21 is tilted, and the limiting component 4 is positioned at a 45-degree angle to the radius of the disc 21. This optimizes material flow, i.e., optimizes scraping force, effectively cleaning while reducing wear, thus significantly improving the yield and quality of granulation. The disc 21 rotates clockwise, and the limiting component 4 is located in the upper half of the disc 21, on the side facing the direction of rotation. This facilitates cleaning of materials adhering to the disc 21. The limiting component 4 includes a main plate 41, an outer plate 42, an inner plate 43, a deflector 5, and a scraper 6. Figures 7-8The main board 41 and the connecting plate 32 are connected by a deflector 5, which helps to adjust the placement angle of the limiting component 4 within the disc 21, thereby optimizing the material flow. Several scrapers 6 are arranged inside the main board 41, enabling timely cleaning of materials within the working mechanism 2. Outer plates 42 are respectively provided at the lower ends of the main board 41, and the outer plates 42 are movably engaged with the outermost scraper 6. Several inner plates 43 are provided in the lower middle part of the main board 41, and one inner plate 43 is movably engaged between two adjacent scrapers 6. The outer plates 42 and inner plates 43 effectively limit and fix the scrapers 6; that is, the outer plate 42 is U-shaped, and the inner plate 43 is I-shaped. The inner walls of the outer plates 42 and inner plates 43 respectively engage with the scraper body 61. The side walls of the scraper body 61 are movable and snap-fitted together. Rubber pads are provided on the inner walls of both the outer plate 42 and the inner plate 43, allowing them to contact the side walls of the scraper body 61. This increases the stability of the scraper body 61 and disperses the impact force, improving its service life. Furthermore, the two side walls of the main plate 41, outer plate 42, and inner plate 43 are all fixedly connected with locking posts 401. The locking posts 401 on the main plate 41 and the outer plate 42 are fixedly snap-fitted together by locking plates 402, and the locking posts 401 on the main plate 41 and the inner plate 43 are fixedly snap-fitted together by locking plates 402. This allows the outer plate 42 and inner plate 43 to be easily and stably connected to the main plate 41, thus aiding in the limiting and fixing of the scraper 6 and enhancing the stability of the scraper 6 during use. Specifically:

[0062] like Figures 5-7 The deflecting component 5 includes a deflecting plate 51 and a deflecting column 52. The deflecting plate 51 is movably snapped onto the connecting plate 32 and is movably connected to the connecting plate 32 by bolts. The bottom end of the deflecting plate 51 is fixedly connected to the top end of the deflecting column 52, and the bottom end of the deflecting column 52 is threadedly connected to the top end of the main board 41. Thus, the main board 41 can be stably fixed on the connecting plate 32 by using the deflecting component 5. It should be noted that the main board 41 rotates around the deflecting column 52 for one revolution, so that its vertical movement distance is small. Thus, by rotating the main board 41 threadedly connected to the deflecting component 5, the angle of the limiting component 4 relative to the radius of the disk 21 can be adjusted to ensure optimized material flow.

[0063] like Figures 5-7The scraper 6 includes a scraper body 61 and a connecting body 62. The upper half of the scraper body 61 is internally and movably engaged with the main board 41. One side of the lower half of the scraper body 61 is arc-shaped, and the other side is vertical. It should be noted that the arc-shaped wall surface of the scraper body 61 will contact the material first compared to the vertical wall surface. That is, the rotation direction of the disc 21 is from the arc-shaped wall surface of the scraper body 61 to the vertical wall surface of the scraper body 61. Therefore, when the scraper body 61 removes material from the working mechanism 2, the material can move along the scraper body 61. The arc-shaped wall surface moves, making it easier for materials to be cleaned and transferred. The top of the scraper body 61 is provided with a threaded groove, and the lower half of the connecting body 62 is provided with threads. The scraper body 61 is threadedly connected to the lower half of the connecting body 62 through the threaded groove. The upper half of the connecting body 62 is movably engaged with the top of the main board 41. When installing the scraper body 61, insert the scraper body 61 from below the main board 41 and align it with the connecting body 62. Rotate the connecting body 62 to gradually connect and fix the scraper body 61 until the set height line of the scraper body 61 is reached.

[0064] By changing the design of the scraper 6 from a single ultra-long design to a multi-segment splicing design, the length of the scraper 6 can be controlled, thereby reducing the overall linear speed difference of the individual scrapers 6 and reducing the wear difference of the individual scrapers 6. This reduces the possibility of deformation or even breakage of the individual scrapers 6, and at the same time, it is easier to replace the individual scrapers 6 when they are damaged, thus reducing costs.

[0065] Example 2, based on Example 1, such as Figures 5-7 The limiting assembly 4 also includes a movable component 7, which is disposed between the two outer plates 42 to assist in cleaning material adhering to the scraper 6. The movable component 7 includes a movable body 71, a rotary motor 72, a rotating block 73, and a rotating ring 74, such as... Figures 8-11The two ends of the movable body 71 are respectively connected to the inner parts of the two outer plates 42. It should be noted that the end of the movable body 71 is close to the vertical wall of the scraper body 61, thus preparing for the movable body 71 to rotate along the scraper body 61. The length of the movable body 71 is longer than the distance of the main plate 41, and the movable body 71 can rotate around the arc-shaped wall of the scraper body 61, so that the wall of the scraper body 61 can be effectively cleaned when the movable body 71 rotates. The distance between the bottom surface of the scraper body 61 and the top surface of the disc 21 is the thickness of the movable body 71. In use, the movable body 71 is in a horizontal state. At this time, there is a certain space gap between the bottom surface of the scraper body 61 and the top surface of the disc 21, ensuring that the sticky material can be scraped off without excessive friction on the disc 21, preventing increased resistance and wear. Furthermore, for calibrating the scraper 6, rotating the movable part 7 to a vertical position allows direct detection of the distance between the top surface of the disc 21 and the bottom surface of the scraper 6, enabling timely detection of severe wear on the scraper 6. If the scraper 6 is severely worn, it needs to be replaced, thus improving the ease of scraper 6 inspection. For installing the scraper 6, rotating the movable part 7 to a vertical position allows for horizontal limitation of multiple scrapers 6 mounted on the main board 41, ensuring that the bottom heights of multiple scrapers 6 are consistent, thereby improving the ease of scraper 6 installation. Additionally, when installing the limiting component 4 onto the connecting plate 32, rotating the movable part 7 to a vertical position allows for vertical adjustment of the limiting component 4 until the bottom surface of the movable part 7 contacts the top surface of the disc 21, thereby improving... The limiting component 4 is easy to install. Both outer plates 42 have internal cavities, and a rotary motor 72 is placed inside one of the cavities. The rotary motor 72 can rotate in both directions, driving the movable body 71 to reciprocate between 0 and 90 degrees, thus achieving friction cleaning of the scraper body 61 by the movable body 71. One end of the movable body 71 is movably connected to the rotary motor 72, and the other end of the rotary motor 72 is fixedly connected to the rotating block 73. A rotating ring 74 is fixedly fitted inside the cavity of the other outer plate 42, and the rotating ring 74 is concentrically arranged with the rotating block 73. The rotating block 73 and the rotating ring 74 have the same magnetism. When the rotary motor 72 is started, it can drive the movable body 71 to rotate, allowing the movable body 71 to switch between a vertical and a horizontal state. Meanwhile, the magnetic design of the rotating block 73 and the rotating ring 74 ensures that the rotating block 73 is always concentrically set with the rotating ring 74, thereby improving the levelness of the moving body 71. This helps the moving body 71 to inspect the bottom surface of multiple scraper bodies 61. An arc groove is opened on one side wall of the outer plate 42 and the inner plate 43, and the arc groove is close to the arc-shaped wall of the scraper body 61. When the moving part 7 is not in use, it can be rotated to a horizontal state and stay in the arc groove to prevent the moving part 7 from affecting the operation of the scraper body 61. When the moving part 7 reciprocates, it can rotate along the bottom of the scraper 6 to clean the material attached to the scraper 6, and it can also knock the outer plate 42 and the inner plate 43 to further vibrate the material attached to the scraper 6, thereby achieving effective cleaning of the scraper 6.

[0066] Example 3, based on Example 2, such as Figures 5-7 The limiting component 4 also includes a cleaning component 8 and a cleaning hole 9. The inner top end of the arc groove is fixedly connected to the top end of the cleaning component 8, and the inner top end and bottom end of the cleaning component 8 are connected by a spring. Figure 12 Both the outer plate 42 and the inner plate 43 located above the arc groove are provided with cleaning holes 9, and the bottom of the cleaning hole 9 is connected to the top of the cleaning component 8. The cleaning hole 9 consists of vertical holes and inclined holes, and several inclined holes are connected to one vertical hole. The inclined holes are designed to be biased towards the scraper body 61, and the ends of the inclined holes are provided with filter screens to effectively reduce the possibility of materials entering the cleaning hole 9 and the cleaning component 8. When the movable part 7 rotates into the arc groove, the movable part 7 effectively squeezes the cleaning component 8, so that the gas in the cleaning component 8 is discharged to the side wall of the scraper 6 through the cleaning hole 9 to achieve further cleaning of the scraper 6. When the movable part 7 rotates out of the arc groove, the cleaning component 8 is expanded by the action of the spring, so that air enters the cleaning component 8 through the cleaning hole 9, which can prepare for the subsequent use of the cleaning component 8.

[0067] The working principle of the method of using this invention is as follows:

[0068] When multiple scraper bodies 61 need to be installed on the main board 41, first insert the scraper body 61 into the main board 41 and fix it with a screw using the connecting body 62. Then, start the rotary motor 72, causing the movable body 71 to rotate from a horizontal state to a vertical state under the action of the rotary motor 72. At this time, the height of multiple scraper bodies 61 can be adjusted so that the bottom surface of the scraper body 61 contacts the top surface of the vertical movable body 71, thereby simultaneously limiting the horizontal position of multiple scrapers 6 to adjust the scrapers 6 and ensure that the bottom height of multiple scrapers 6 is consistent, thus improving the ease of installation of the scrapers 6. After completion, rotate the movable body 71 from a vertical state to a horizontal state, and the multiple scraper bodies 61 are jointly limited and fixed by the outer plate 42 and the inner plate 43. Finally... The limiting component 4 is stably fixed on the connecting plate 32 by the deflector 5, and the angle between the limiting component 4 and the disk 21 can be adjusted by the deflector 5 so that the placement of the limiting component 4 forms a 45-degree angle with the radial direction of the disk 21. This optimizes the material flow, that is, optimizes the scraping force, effectively cleans and reduces wear, thereby significantly improving the yield and quality of granulation. In summary, the scraper 6 has changed from a single ultra-long design to a multi-segment splicing design, which makes the length of the scraper 6 controllable, reduces the overall linear velocity difference of individual scrapers 6, and reduces the wear difference of individual scrapers 6. This reduces the possibility of individual scrapers 6 being deformed or even broken due to external impact during use. At the same time, it is easy to replace when an individual scraper 6 is damaged, thus reducing costs.

[0069] When the scraper 6 needs to be inspected, the movable part 7 is rotated from a horizontal state to a vertical state. At this time, the distance between the top surface of the disc 21 and the bottom surface of the scraper 6 can be directly measured through the movable part 7, so as to detect whether the scraper 6 is severely worn in time. If the scraper 6 is severely worn, it needs to be replaced, thereby improving the convenience of scraper 6 inspection.

[0070] When the scraper 6 needs to be cleaned, the rotary motor 72 is started to make the movable body 71 reciprocate. The movable body 71 can rotate along the bottom of the scraper 6 to clean the material attached to the scraper 6, and the movable body 71 can also hit the arc grooves of the outer plate 42 and the inner plate 43 to vibrate the material attached to the scraper 6, thereby achieving effective cleaning of the scraper 6. At the same time, if the movable part 7 rotates into the arc groove, the movable part 7 effectively squeezes the cleaning part 8, so that the gas in the cleaning part 8 is discharged to the side wall of the scraper 6 through the cleaning hole 9. If the movable part 7 rotates out of the arc groove, the cleaning part 8 is expanded by the spring, so that air enters the cleaning part 8 through the cleaning hole 9, which can prepare for the subsequent use of the cleaning part 8. This process is repeated to achieve further cleaning of the scraper 6.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention.
