Description

Technical Field

[0001] This utility model relates to the field of disc granulation technology, specifically to a disc granulation device for preparing ceramsite. Background Technology

[0002] In the preparation of non-fired ceramsite, the disc granulator is one of the commonly used pieces of equipment. Its working principle is that raw materials are mixed in a certain proportion and fed into the disc granulator. Under the rotation of the disc, the materials continuously tumble and agglomerate within the disc, gradually forming ceramsite particles through the spraying of binders and water. Finally, the non-fired ceramsite is prepared through drying and curing processes. However, traditional disc granulators have some shortcomings in practical applications. First, the fixed disc angle cannot meet the granulation requirements of various materials due to the significant differences in their flowability, resulting in poor material movement within the disc and a generally low pelletizing rate, typically below 75%. Second, the particle size separation method is coarse. Traditional equipment mostly relies on a single baffle for preliminary screening or requires manual secondary screening, making it difficult to accurately separate ceramsite particles that meet the particle size requirements, resulting in a low percentage of qualified particles, generally not exceeding 70%. Third, the equipment lacks sufficient wear and corrosion resistance. Due to the characteristics of the raw materials and binders in the non-fired ceramsite, materials easily adhere to the disc surface during the granulation process, affecting the granulation effect and efficiency. Furthermore, the baffles used for sorting have a short service life in corrosive environments, typically less than six months. Although existing technologies attempt to improve the disc surface adhesion problem through surface coating treatments, this is merely a repair of local defects and fails to fundamentally address the key requirements of dynamic adjustment of the disc inclination angle and accurate particle size classification. Therefore, developing a gravity gradient grading disc granulation device for non-fired ceramsite that can dynamically adjust the inclination angle according to material characteristics, achieve automatic particle size classification, and possess good wear and corrosion resistance is an urgent problem to be solved. Utility Model Content

[0003] To address the problems existing in the prior art, the purpose of this utility model is to provide a disc granulation device for preparing ceramsite, which can dynamically balance and adjust the tilt angle, achieve particle size sorting, and has high wear resistance and corrosion resistance, so as to improve the pelletizing rate, particle size qualification rate and equipment life.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A disc granulation device for preparing ceramsite, the disc granulation device comprising: a base having a material collection trough; a disc rotatably disposed above the base, the top of the disc being open and having a granulation space inside for containing material; a material turning assembly disposed at the bottom of the disc, the material turning assembly being used to drive the disc to rotate and to turn the material within the granulation space as the disc rotates; and a drive assembly disposed on the base and retractably connected to the material turning assembly, such that the disc is tilted relative to the base at an angle α.

[0006] According to one example, the base includes a flat plate and a plurality of support feet disposed at the bottom of the flat plate, the support feet raising the flat plate a certain distance off the ground, the material collection trough being located below the flat plate, and the drive assembly being fixed to the flat plate.

[0007] According to one example, the material turning assembly includes a central column and a plurality of support rods. The central column is rotatably connected to the bottom of the disc body. One end of each of the plurality of support rods is fixed to the central column, while the other end extends radially toward the side wall of the disc body and is slidably connected to the disc body. One of the support rods is provided with at least one material turning blade and extends into the granulation space.

[0008] According to one example, the bottom of the disc has an annular rack, a motor is mounted on the support rod, and a transmission gear is mounted on the output end of the motor, the transmission gear meshing with the annular rack.

[0009] According to one example, a support rod is provided on the base, and a transmission rod is rotatably provided at the upper end of the support rod. The first end of the transmission rod is connected to the support rod, and the second end of the transmission rod is rotatably connected to the drive assembly.

[0010] According to one example, the transmission rod is provided with a counterweight for maintaining the balance of the disc.

[0011] According to one example, the drive assembly includes a hydraulic cylinder connected to the base and a piston rod telescopically connected to the hydraulic cylinder, the piston rod being rotatably connected to a second end of the transmission rod.

[0012] According to one example, the α angle is 30-60 degrees.

[0013] According to one example, the disc granulation device further includes a sorting component comprising an arc plate and a support. The arc plate is located within the granulation space and is detachably connected to the turning blades via the support. The arc plate includes arc segments and curved segments arranged in series. The arc segments are provided with multiple through holes for screening materials, and the discharge end of the curved segments extends beyond the disc body.

[0014] According to one example, the disc granulation device further includes a spray assembly comprising a rotating rod and a nozzle, one end of the rotating rod being rotatably connected to a side wall of the base, and the other end of the rotating rod being detachably connected to the nozzle, the nozzle being oriented toward the granulation space.

[0015] This utility model has the following advantages:

[0016] 1. The drive assembly of this utility model employs two symmetrically arranged hydraulic cylinders to control the extension and retraction of the piston rod, achieving precise adjustment of the tilt angle α of the disc relative to the base, with an adjustment accuracy of ±0.5°. This allows the disc granulator to flexibly adjust the disc tilt angle according to the flowability and process requirements of different materials, optimizing the material's movement trajectory and stress state within the disc, thereby improving granulation efficiency and product quality. The support rod on the base cooperates with the transmission rod, and the first, second, and third connecting rods of the transmission rod form a stable transmission structure. The counterweight block set on the transmission rod can slide on the guide rail of the third connecting rod, and by adjusting its position and weight, the center of gravity position of the entire transmission rod system can be changed. When the disc becomes unbalanced due to changes in tilt angle or uneven material distribution, the operator adjusts the counterweight block based on monitoring data, using the reverse torque generated by its gravity to counteract the disc tilting trend, ensuring that the disc remains balanced during tilting and rotation, reducing equipment vibration and failure risks, and ensuring stable equipment operation. This utility model improves the pelletizing rate to ≥90% and the particle size qualification rate to >92%.

[0017] 2. The arc-shaped plate of the sorting component of this utility model is located within the granulation space and is detachably connected to the turning blades via a bracket. The arc-shaped section of the plate closely conforms to the concave curved surface contour of the disc, and multiple through holes on it can screen materials. Materials with a particle size larger than the diameter of the through holes remain on the surface of the arc-shaped section, continue to rotate with the disc, and finally extend outward along the curved section to the outlet channel outside the disc to obtain materials that conform to the particle size. Materials with a particle size smaller than the diameter of the through holes leak through the through holes under the action of gravity and centrifugal force and return to the granulation space for further granulation. By replacing the arc-shaped plate with different hole diameters, precise grading and discharge of materials can be achieved.

[0018] 3. The disc body of this utility model is made of carbon fiber reinforced aluminum alloy, which has high material strength and can withstand the stress generated by long-term high-speed operation. Simultaneously, the disc body surface is coated with a PTFE coating, effectively reducing material wear on the disc surface and extending the disc's wear-resistant life to ≥2 years, thus reducing equipment maintenance costs and replacement frequency. The arc plate of the sorting component uses PREN 2205 duplex stainless steel as the base material, which has excellent resistance to pitting and crevice corrosion. The surface is coated with titanium nitride (TiN) coating, further improving its hardness and corrosion resistance, extending the arc plate's salt spray corrosion resistance to >1000h and extending the disc's wear-resistant life to ≥2 years.

Detailed Implementation

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0027] Reference Figure 1-3 The illustration shows an embodiment of a disc granulation device A, which mainly includes a base 1, a disc body 2, a material turning assembly 3, and a drive assembly 4 disposed above the base 1. The base 1 includes a flat plate 102 and multiple support feet 103 disposed at the bottom of the flat plate 102. The support feet 103 raise the flat plate 102 a certain distance from the ground. Four support feet 103 are symmetrically arranged at the bottom of the flat plate 102 to ensure that the flat plate 102 can be stably installed on the ground, reserving sufficient space for the material collection trough 101. The number of support feet 103 can also be two, six, etc.

[0028] The collecting trough 101 has a rectangular parallelepiped structure and is arranged parallel to the plate 102. The length of the collecting trough 101 is greater than the length of the plate 102, so that the end of the collecting trough 101 protrudes from the front or rear end of the plate 102, thus forming a receiving port. In actual production, after the shaped ceramsite is discharged from the inside of the disc 2, it can fall directly into the collecting trough 101 through this receiving port, effectively preventing material scattering and improving material collection efficiency and the cleanliness of the production environment. In addition, the collecting trough 101 is detachably connected to the base 1, and after production is completed, the entire collecting trough 101 can be separated and removed for easy access to the shaped material.

[0029] Continue to refer to Figure 1-3 The disc 2 is positioned above the base 1. The disc 2 is circular in shape, ensuring more even force distribution when the material rolls within it, which improves the roundness and consistency of the ceramsite pellets. Its top is completely open to form both an inlet and outlet. The interior has a concave surface to create a granulation space 2a for accommodating the material. Alternatively, the disc 2 can be elliptical or another suitable shape. During disc 2 operation, the material moves towards the edge of the disc 2 under centrifugal force, and then, driven by gravity and the turning component 3, falls back along the concave surface and rolls again. This cycle repeats continuously, achieving thorough mixing and shaping of the material.

[0030] The disc body 2 has a diameter of 2000mm and can be made of carbon fiber reinforced aluminum alloy with a density ≤2.8g / cm³. 3 It can withstand the stress generated by long-term high-speed operation. The surface of the disc body 2 is coated with a PTFE coating with a thickness of 0.2mm±0.05mm and an adhesion of ≥8MPa.

[0031] In this design, one side of the disc 2, at a lower height, is designated as the discharge end, while the other side of the disc 2, at a higher height, is designated as the turning end. The lower side of the disc 2, as the discharge end, allows the formed ceramsite to be smoothly discharged into the collection trough 101 by the combined action of gravity and centrifugal force during the tilting and rotation of the disc 2. Conversely, the higher side of the disc 2, as the turning end, has a turning component located near it. When the material reaches the turning end, the turning component 3 turns and pushes the material, causing it to re-enter the center of the granulation space 2a, thus creating a cyclical movement trajectory of the material within the disc 2.

[0032] Reference Figure 2-4 The material-turning component 3 is located at the bottom of the disc body 2. It drives the disc body 2 to rotate and turns the material within the granulation space 2a as the disc body 2 rotates. In other words, the turning component is relatively fixed, and the rotation of the disc body 2 and the turning of the material are achieved through the turning component. The material-turning component 3 includes a central column 301 and multiple support rods 302. The central column 301 is rotatably connected to the bottom of the disc body 2 and located on its central axis, achieving a rotatable connection with the bottom of the disc body 2 through bearings or bushings. In this embodiment, three support rods 302 extend outward from the central column 301, with an included angle of 60 degrees between adjacent support rods 302, forming a Y-shaped structure. One support rod 302 extends vertically to the vicinity of the material-turning end of the disc body 2, while the other two support rods 302 extend towards the discharge end at a predetermined inclination angle.

[0033] Each of the multiple support rods 302 has one end fixed to the central column 301, while the other end extends radially toward the side wall of the disc 2 and is slidably connected to the disc 2. A roller 302a is disposed at the other end of the support rod 302, and the roller 302a abuts against the outer side wall of the disc 2. Through the rolling contact between the roller 302a and the side wall of the disc 2, the supporting force of the support rod 302 on the disc 2 is converted into rolling friction, thereby reducing the resistance when the disc 2 rotates and ensuring smooth rotation. Furthermore, an additional roller can be added in the middle of the support rod 302, and through multi-point support and rolling contact, the load during the rotation of the disc 2 is distributed, effectively reducing the shaking and vibration of the disc 2.

[0034] At least one turning blade 303 is mounted on a support rod 302 located near the turning end. Two mutually perpendicular turning blades 303 are located within the granulation space 2a inside the disc 2. When the disc 2 rotates, the material actively contacts the turning blades 303 to turn and push the material. The two mutually perpendicular turning blades 303 can apply force to the material from multiple directions during the rotation of the disc 2, preventing material accumulation in localized areas and ensuring that the material is fully turned, mixed, and agglomerated within the granulation space 2a. In this embodiment, the turning blade 303 includes two turning rods arranged perpendicularly to the disc 2 and a connecting rod connecting the two turning rods.

[0035] Continue to refer to Figure 3 and Figure 4 A ring rack 201 is arranged around the bottom of the disc body 2 in a circumferential direction. A motor 304 is mounted on a support rod 302, and a transmission gear 305 is provided at the output end of the motor 304. The transmission gear 305 meshes with the ring rack 201. The motor 304 is mounted on one of the support rods 302 of the tilting assembly. When the motor 304 operates, it converts electrical energy into rotational mechanical energy, which is transmitted to the transmission gear 305 through the output shaft. Driven by the motor 304, the transmission gear 305 performs circumferential motion. Through the meshing of the gear teeth with the ring rack 201, the rotational power is transmitted to the disc body 2, thereby driving the disc body 2 to rotate around the central axis. This transmission method can make full use of space layout, reduce external drive equipment, and the power transmission path is short and direct, reducing energy loss during transmission and improving transmission efficiency.

[0036] Reference Figure 2 and Figure 3 The drive assembly 4 is mounted on the base 1 and retractably connected to the tilting assembly 3, used to adjust the tilt angle of the disc 2. The drive assembly 4 includes a hydraulic cylinder 401 and a piston rod 402 retractably connected to the hydraulic cylinder 401. The piston rod 402 is rotatably connected to the second end of the transmission rod 306. A lug is provided on the plate 102. The hydraulic cylinder 401 is hinged to the lug of the plate 102 via a pin. The pin has a tolerance of Φ30H7 / g6. One end of the hydraulic cylinder 401 has a perforated plate that matches the lug. The perforated plate and the lug are connected through the pin to form a hinged structure.

[0037] There are two hydraulic cylinders 401, symmetrically arranged, with a stroke of 200mm and a thrust of 5T. They are equipped with built-in synchronous flow dividers, ensuring a flow error of <2%. Displacement sensors are also installed on each hydraulic cylinder 401 to monitor its extension and retraction displacement, thereby precisely controlling the tilt angle of the disc 2. These displacement sensors are magnetostrictive, with an accuracy of ±0.05%FS, and feature redundant dual-sensor cross-validation.

[0038] The drive assembly 4 controls the extension and retraction of the piston rod 402 of the hydraulic cylinder 401, thereby pushing the connected material-turning assembly 3, and thus adjusting the tilt angle α of the disc 2 relative to the base 1. The α angle ranges from 30 to 60 degrees, with a preferred α angle of 40 degrees. This adjustable tilt angle of the disc 2 allows the disc granulator A to flexibly adjust the tilt angle of the disc 2 according to the characteristics of different materials and granulation process requirements, optimizing the movement trajectory and force state of the material within the disc 2, thereby improving granulation efficiency and product quality.

[0039] Exhibitor Figure 4 A support rod 105 is provided on the plate 102 of the base 1. A transmission rod 306 is rotatably provided on the upper end of the support rod 105 to ensure that the transmission rod 306 can swing when subjected to force. The first end of the transmission rod 306 is connected to the support rod 302, and the second end of the transmission rod 306 is rotatably connected to the drive assembly 4. There are two support rods 105, and the two support rods 105 are arranged side by side on the plate 102. As shown in the figure, the transmission rod 306 includes a first connecting rod 306a, a second connecting rod 306b, and a third connecting rod 306c. The first connecting rod 306a is horizontally mounted between two support rods 302 near the discharge end, and its two ends are connected to the two support rods 302 by welding or bolts respectively. There are two second connecting rods 306b, which are Y-shaped. The first end of the second connecting rod 306b is connected to the first connecting rod 306a, and its second end is hinged to the upper end of the support rod 105. It can rotate at multiple angles during the tilting process of the disc 2 to adapt to the tilt angle change of the disc 2. Its third end is connected to the end of the piston rod 402 of the drive assembly 4. Specifically, one end of the piston rod 402 is provided with a lug, and the third end of the second connecting rod 306b forms a connecting hole. The lug is connected to the connecting block by a pin to ensure that the extension force of the piston rod 402 can be transmitted to the disc 2 under the drive of the hydraulic cylinder 401.

[0040] One end of the third connecting rod 306c is connected to the middle of the first connecting rod 306a, and the other end extends away from the disc 2. It serves as the mounting carrier for the counterweight 307 and plays a dual role in balance adjustment and force transmission in the overall structure.

[0041] The transmission rod 306 is equipped with a counterweight 307 to maintain the balance of the disc 2. The counterweight 307, by adjusting its position and weight, keeps the disc 2 balanced during tilting and rotation. The counterweight 307 is slidably connected to a third connecting rod 306c, which is equipped with a guide rail. The counterweight 307 slides along the guide rail on the third connecting rod 306c. This configuration allows for changing the center of gravity of the entire transmission rod 306 system. When the tilt angle of the disc 2 changes or when uneven material distribution causes force imbalance, the operator can adjust the position of the counterweight 307 based on monitoring data, such as feedback data from tilt and vibration sensors installed on the disc 2. When the disc 2 tilts to one side, the counterweight 307 is slid in the opposite direction, using its gravity to generate a counter-torque to counteract the tilting tendency of the disc 2. Furthermore, by increasing or decreasing the number of counterweights 307 or replacing them with counterweights of different masses, the balancing torque can be precisely fine-tuned.

[0042] Reference Figure 5 The disc granulation device A also includes a spray assembly 6, which includes a rotating rod 601 and a nozzle 602. One end of the rotating rod 601 is rotatably connected to one side of the base 1, and the other end is detachably connected to the nozzle 602, which faces the granulation space 2a. A lug 104 is provided on one side of the base 1, and one end of the rotating rod 601 has a perforated plate that mates with the lug 104, allowing for multi-angle position adjustment of the nozzle 602 in both horizontal and vertical directions. The other end of the rotating rod 601 has a U-shaped locking block 601a, which can engage the nozzle 602 for replacing different models of nozzles. Of course, besides the locking method, the detachable connection between the rotating rod 601 and the nozzle 602 can also be achieved using ball joints, bolts, or other methods. For example, the ball joint allows the nozzle 602 to rotate freely in three-dimensional space, further enhancing the flexibility of spray angle adjustment; the bolt connection secures the nozzle 602 to the rotating rod 601 with bolts, improving the stability of the connection. The spray liquid that the nozzle 602 sprays can be water, adhesive, etc.

[0043] Reference Figure 6The disc granulation device A also includes a sorting component 5, which includes an arc plate 501 and a support 502. The arc plate 501 is located in the granulation space 2a and is detachably connected to the turning blade 303 through the support 502. The arc plate 501 is located near the discharge end of the disc body 2. The arc plate 501 includes an arc section 501a and a curved section 501b arranged in series. The arc section 501a closely fits the concave curved surface contour of the disc body 2. Multiple through holes 501a1 for screening materials are provided on the arc section 501a. When the disc body 2 rotates, a portion of the material moves with the turning blade 303 and enters the arc section 501a. The material with a particle size larger than the diameter of the through hole 501a1 remains on the surface of the arc section 501a and continues to rotate with the disc body 2. Finally, it extends outward along the curved section to the discharge channel outside the disc body and is discharged to obtain material that meets the particle size requirements. Materials with a particle size smaller than the diameter of the through-hole 501a1 are discharged through the through-hole 501a1 under the action of gravity and centrifugal force and return to the granulation space for further granulation. In other words, the discharge end of the disc 2 no longer serves as the discharge point; instead, the discharge is achieved by the curved section 501b of the arc-shaped plate 501, thus separating materials of different particle sizes. By replacing the arc-shaped plates 501 with through-holes 501a1 of different diameters, the separation of materials of different particle sizes can be achieved, meeting the production needs of ceramsite of different particle sizes.

[0044] The curved section 501b extends beyond the disc body 2, forming an outlet channel. A baffle 501b1 is provided on the side of the curved section 501b, perpendicular to the material conveying direction, effectively preventing material retained on the curved section 501a from returning to the granulation space 2a during conveying. During the rotation of the disc body 2, after the material enters the curved section 501b along the curved section 501a, it is smoothly discharged from the disc body 2 along the guide path of the curved section 501b under the drive of centrifugal force and gravity, achieving graded material discharge.

[0045] Among them, the curved plate 501 uses 2205 duplex stainless steel as the base material, with a PREN (pitting resistance equivalent) value ≥35, and the surface of the curved plate 501 is coated with a titanium nitride (TiN) coating with a thickness of 3μm.

[0046] In an embodiment not shown, an industrial camera is also provided above the disc 2. The industrial camera is connected to the base 1 via a support frame and is used to monitor the particle size of the material inside the granulation space 2a in order to adjust the tilt angle of the disc 2.

[0047] The above embodiments are preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present invention should be considered equivalent substitutions and are included within the protection scope of the present invention.
