Detailed Implementation

[0036] To better understand the above-mentioned objectives, features, and advantages of this utility model, the solution of this utility model will be further described below. It should be noted that, unless otherwise specified, the embodiments of this utility model and the features thereof can be combined with each other.

[0037] Many specific details are set forth in the following description in order to provide a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of the present invention, and not all embodiments.

[0038] The granulator provided in this embodiment of the invention utilizes a rotating shaft with a forward-propelling paddle and a stirring rod, and a damping rod positioned between the granulation cylinder wall and the rotating shaft. When material enters the granulation cylinder, it enters the processing section under the action of the forward-propelling paddle. In the processing section, the material undergoes stirring, kneading, shearing, and extrusion under the action of the stirring rod, damping rod, and rotating shaft to form uniform spherical particles. These spherical particles then enter the discharge section and exit through the discharge port under the action of the stirring rod. This allows for the recycling of tailings or sludge, obtaining granules that meet specific requirements. Therefore, the granulator provided in this embodiment of the invention can adjust the kneading, shearing, and extrusion forces for different tailings or sludge to achieve the required spherical particles, enabling continuous feeding and high-capacity production.

[0039] The granulator provided in the embodiments of this utility model will be described exemplarily below with reference to the accompanying drawings.

[0040] Figure 1 This is a schematic diagram of the structure of a granulator provided in an embodiment of the present invention. Figure 2 This is a schematic diagram of a granulator for removing the shell, provided by an embodiment of the present invention. Figure 3 This is a schematic diagram of a granulation component provided in an embodiment of the present invention. It should be noted that, in order to clearly illustrate the internal structure of the granulation component, Figure 3 The complete granulation cylinder structure is not shown.

[0041] like Figures 1 to 3 As shown, the granulator 10 includes: a granulator body 25; the granulator body 25 includes a drive assembly, a granulation assembly 33, and a support 23; the granulation assembly 33 includes a granulation cylinder 11 and a granulation structure, the granulation cylinder 11 being fixedly mounted on the support 23 in a horizontal direction; the granulation structure includes a rotating shaft 12, a forward propulsion paddle 13, a stirring rod 14, and a damping rod 15; the rotating shaft 12 is mounted in the granulation cylinder 11 in a horizontal direction, and end caps 24 are provided at both ends of the granulation cylinder 11, with a through hole at the center of the end cap 24, through which both ends of the rotating shaft 12 extend.

[0042] The granulation cylinder 11 has an inlet 16 and an outlet 17 on its wall. The inlet 16 is located at the top of the granulation cylinder 11 and is adjacent to the first end A1 of the granulation cylinder 11. The outlet 17 is located at the bottom of the granulation cylinder 11 and is adjacent to the second end A2 of the granulation cylinder 11. The rotating shaft 12 extending from the first end A1 of the granulation cylinder 11 is connected to the drive assembly.

[0043] The rotating shaft 12 includes a feeding section 19, a processing section, and a discharging section 21 arranged sequentially; the feeding section 19 is arranged corresponding to the feeding port 16, and the forward propulsion blades 13 are arranged on the feeding section 19 at preset distances; the discharging section 21 is arranged corresponding to the discharging port 17, and the stirring rods 14 are arranged on the discharging section 21 at preset distances.

[0044] The processing section 20 includes a first processing section 201; the stirring rod 14 is arranged on the first processing section 201 at a preset distance, and a first damping rod 151 is arranged between the first processing section 201 and the wall of the granulation cylinder 11. The first damping rod 151 is arranged at a preset distance along the direction of the rotation axis 12, and one end of the first damping rod 151 is located on the cylinder wall.

[0045] Specifically, Figure 3 In the diagram, X1 indicates the feeding direction, X2 indicates the discharging direction, Y indicates the forward propulsion direction of the material, and Y' indicates the reverse propulsion direction of the material.

[0046] Specifically, when the granulator 10 is working, the drive assembly provides driving force to the granulation assembly 33, allowing the rotating shaft 12 to rotate at high speed. Materials such as tailings or sludge are fed into the granulation cylinder 11 through the feeding opening structure 30 on the housing 32 and the feeding port 16 on the cylinder wall. The material enters the feeding section 19, and under the action of the forward propulsion paddles 13 on the feeding section 19, the material is propelled to the first processing section 201. A stirring rod 14 is provided on the first processing section 201, and a first damping rod 151 is provided on the granulation cylinder 11 corresponding to the first processing section 201. Under the action of the stirring rod 14, the first damping rod 151 and the rotating shaft 12, the material at the first processing section 201 is stirred, kneaded, sheared and squeezed to form uniform round particles, and then enters the discharge section 21. The round particles are discharged from the discharge port 17 under the action of the stirring rod 14, thereby realizing the recyclability of tailings or sludge and obtaining particles that meet the requirements.

[0047] The granulator provided in this embodiment of the invention utilizes a rotating shaft with a forward-propelling paddle and a stirring rod, and a damping rod positioned between the granulation cylinder wall and the rotating shaft. When material enters the granulation cylinder, it enters the processing section under the action of the forward-propelling paddle. In the processing section, the material undergoes stirring, kneading, shearing, and extrusion under the action of the stirring rod, damping rod, and rotating shaft to form uniform spherical particles. These spherical particles then enter the discharge section and exit through the discharge port under the action of the stirring rod, thus enabling the recycling of tailings or sludge to obtain particles that meet specific requirements. Therefore, the granulator provided in this embodiment of the invention can adjust the kneading, shearing, and extrusion forces for different tailings or sludge to achieve the required spherical particles, enabling continuous feeding and high-capacity production.

[0048] In some embodiments, such as Figure 3 As shown, the processing segment 20 further includes a second processing segment 202 and a third processing segment 203, wherein the first processing segment 201, the second processing segment 202 and the third processing segment 203 are arranged sequentially;

[0049] The forward propulsion blade 13 is provided on the second processing section 202, the stirring rod 14 is provided on the third processing section 203 at a preset distance, and a second damping rod 152 is provided between the third processing section 203 and the cylinder wall of the granulation cylinder 11. The second damping rod 152 is provided at a preset distance along the direction of the rotation axis 12, and one end of the second damping rod 152 is located on the cylinder wall.

[0050] Specifically, when the viscosity of the material, such as sludge, is high, in order to obtain more uniformly dispersed particles, this embodiment of the invention provides a second processing section 202 and a third processing section 203 based on the first processing section 201.

[0051] In this embodiment, the forward propulsion paddle 13 is installed on the second processing section 202. Under the action of the forward propulsion paddle 13, the material processed in the first processing section 201 can advance to the third processing section 203. The third processing section 203 is equipped with a stirring rod 14 and a second damping rod 152. Under the action of the stirring rod 14, the second damping rod 152, and the quasi-rotation of the rotating shaft 12, the material in the third processing section 203 is stirred, kneaded, sheared, and squeezed to form uniform spherical particles. Thus, through this embodiment of the invention, based on the material processed in the first processing section 201, the material is further processed in the third processing section 203. When the viscosity of the material, such as sludge, is high, uniformly dispersed particles can be obtained, thereby meeting the requirements.

[0052] In some embodiments, such as Figure 3As shown, the positive propulsion blades 13 on the second processing section 202 include two blades, and the extension directions of the two positive propulsion blades 13 are perpendicular to each other;

[0053] The forward propulsion blade 13 on the second processing section 202 includes two forward propulsion blade halves disposed opposite to each other on the rotation shaft 12.

[0054] Specifically, two forward propulsion blades 13 can be arranged at a predetermined distance on the second processing section 202 of the rotating shaft 12. Each forward propulsion blade 13 includes two forward propulsion blade halves arranged opposite each other on the second processing section 202, and the extending directions of the two forward propulsion blades 13 are perpendicular to each other. Thus, during the rotation of the rotating shaft 12, the forward propulsion blades 13 can fully contact the material and propel the material forward to the position of the third processing section 203.

[0055] For example, such as Figure 3 At the location of the rotating shaft 12 currently shown, one of the two forward propulsion blades 13 extends parallel to the X1 direction, while the other extends perpendicular to X1. As the rotating shaft 12 rotates, the extending directions of the two forward propulsion blades 13 change, but remain perpendicular. Each forward propulsion blade 13 comprises two blade halves positioned opposite each other on the rotating shaft 12.

[0056] It should be noted that, according to the actual granulation results, two forward propulsion blades 13 on the second processing section 202 are sufficient. Setting one blade is insufficient to achieve the desired granulation effect, and setting more blades will not result in any difference in granulation effect compared to setting two blades.

[0057] In some embodiments, such as Figure 3 As shown, the stirring rod 14 on the third processing section 203 includes two sets of stirring rods, the extension direction of one set of stirring rods is perpendicular to the extension direction of the other set of stirring rods; the extension directions of two adjacent stirring rods 14 are different; the stirring rod 14 on the third processing section 203 includes two stirring rod 14 halves that are arranged opposite to each other on the rotating shaft 12.

[0058] Specifically, multiple stirring rods 14 can be arranged at preset intervals on the third processing section 203 of the rotating shaft 12. The stirring rods 14 are divided into two groups, with the extension direction of one group of stirring rods perpendicular to the extension direction of the other group of stirring rods, and the extension directions of adjacent stirring rods 14 are different. Thus, during the rotation of the rotating shaft 12, the stirring rods 14 can fully contact the material to stir it. At the same time, combined with the second damping rod 152 arranged between the third processing section 203 and the cylinder wall of the granulation cylinder 11, under the action of the stirring rods 14, the second damping rod 152, and the rotation of the rotating shaft 12, the material in the third processing section 203 is stirred, kneaded, sheared, and squeezed to form uniform spherical particles.

[0059] For example, such as Figure 3 The rotating shaft 12 is currently positioned relative to the two sets of stirring rods mounted on the third processing section 203. One set of stirring rods extends parallel to the X1 direction, while the other set extends perpendicular to X1. As the rotating shaft 12 rotates, the extending directions of the two sets of stirring rods change, but remain perpendicular. Each stirring rod 14 on the third processing section 203 comprises two stirring rod halves positioned opposite each other on the rotating shaft 12.

[0060] For example, such as Figure 3 As shown, six stirring rods 14 can be set on the third processing section 203. The six stirring rods 14 are divided into two groups of stirring rods, and each group of stirring rods includes three stirring rods 14. This embodiment of the utility model does not specify the number of stirring rods 14, as long as the requirements are met.

[0061] In some embodiments, such as Figure 3 As shown, the forward propulsion blades 13 on the feed section 19 include two sets of forward propulsion blades 13. The extension direction of one set of forward propulsion blades 13 is perpendicular to the extension direction of the other set of forward propulsion blades 13. The extension directions of two adjacent forward propulsion blades 13 are different.

[0062] The forward propulsion blades 13 on the feed section 19 include two forward propulsion blade halves disposed opposite each other on the rotating shaft 12.

[0063] Specifically, multiple forward propulsion blades 13 can be spaced out on the feed section 19 of the rotating shaft 12. The forward propulsion blades 13 are divided into two groups, with the extension direction of one group of forward propulsion blades perpendicular to the extension direction of the other group, and the extension directions of adjacent forward propulsion blades 13 being different. Thus, when the material enters the granulation cylinder 11 through the feed inlet 16, corresponding to the position of the feed section 19, during the rotation of the rotating shaft 12, the forward propulsion blades 13 on the feed section 19 can fully contact the newly entered material and propel the material forward to the position of the processing section 20.

[0064] For example, such as Figure 3 The rotating shaft 12, as shown currently, is positioned relative to two sets of forward propulsion blades mounted on the feed section 19. One set of forward propulsion blades extends in a direction parallel to X1, while the other set extends in a direction perpendicular to X1. As the rotating shaft 12 rotates, the extension directions of the two sets of forward propulsion blades change, but remain perpendicular. Each forward propulsion blade 13 mounted on the feed section 19 comprises two blade halves positioned opposite each other on the rotating shaft 12.

[0065] For example, such as Figure 3 As shown, six forward propulsion blades 13 can be installed on the feeding section 19. The six forward propulsion blades 13 are divided into two groups of forward propulsion blades, and each group of forward propulsion blades includes three forward propulsion blades 13. This utility model embodiment does not specify the number of blades to be installed, as long as the requirements are met.

[0066] In some embodiments, such as Figure 3 As shown, the stirring rod 14 on the first processing section 201 includes two sets of stirring rods, the extension direction of one set of stirring rods is perpendicular to the extension direction of the other set of stirring rods; the extension directions of two adjacent stirring rods 14 are different.

[0067] The stirring rod 14 on the first processing section 201 includes two stirring rod halves disposed opposite each other on the rotating shaft 12.

[0068] Specifically, multiple stirring rods 14 can be arranged at preset intervals on the first processing section 201 of the rotating shaft 12. The stirring rods 14 are divided into two groups, with the extension direction of one group of stirring rods perpendicular to the extension direction of the other group of stirring rods, and the extension directions of adjacent stirring rods 14 are different. Thus, during the rotation of the rotating shaft 12, the stirring rods 14 can fully contact the material to stir it. At the same time, combined with the multiple first damping rods 151 arranged between the first processing section 201 and the cylinder wall of the granulation cylinder 11, under the action of the stirring rods 14, the first damping rods 151, and the rotation of the rotating shaft 12, the material in the first processing section 201 is stirred, kneaded, sheared, and squeezed to form uniform spherical particles.

[0069] For example, such as Figure 3 The rotating shaft 12 is currently positioned relative to the two sets of stirring rods mounted on the first processing section 201. One set of stirring rods extends parallel to the X1 direction, while the other set extends perpendicular to X1. As the rotating shaft 12 rotates, the extending directions of the two sets of stirring rods change, but they remain perpendicular. Each stirring rod 14 mounted on the first processing section 201 comprises two stirring rod halves positioned opposite each other on the rotating shaft 12.

[0070] For example, such as Figure 3 As shown, eight stirring rods 14 can be set on the first processing section 201. The eight stirring rods 14 are divided into two groups of stirring rods, and each group of stirring rods 14 includes four stirring rods 14. This embodiment of the utility model does not specify the number of stirring rods 14, as long as the requirements are met.

[0071] In some embodiments, such as Figure 3 As shown, the stirring rods 14 on the discharge section 21 include two sets of stirring rods, the extension direction of one set of stirring rods is perpendicular to the extension direction of the other set of stirring rods; the extension directions of two adjacent stirring rods 14 are different.

[0072] The stirring rod 14 on the discharge section 21 includes two stirring rod halves disposed opposite to each other on the discharge section 21.

[0073] Specifically, multiple stirring rods 14 can be arranged at preset intervals on the discharge section 21 of the rotating shaft 12. The stirring rods 14 are divided into two groups, with the extension direction of one group of stirring rods perpendicular to the extension direction of the other group of stirring rods, and the extension directions of adjacent stirring rods 14 being different. Thus, under the action of the stirring rods 14, the material is discharged from the discharge port 17, which helps to disperse the material and obtain particles that meet the requirements.

[0074] For example, such as Figure 3 The rotating shaft 12, as shown currently, is positioned relative to two sets of stirring rods installed on the discharge section 21. One set of stirring rods extends parallel to the X1 direction, while the other set extends perpendicular to X1. As the rotating shaft 12 rotates, the extending directions of the two sets of stirring rods change, but they remain perpendicular. Each stirring rod 14 comprises two stirring rod halves positioned opposite each other on the rotating shaft 12.

[0075] For example, such as Figure 3 As shown, four stirring rods 14 can be set on the discharge section 21. The four stirring rods 14 are divided into two groups of stirring rods, and each group of stirring rods includes two stirring rods 14. This utility model embodiment does not specify the number of stirring rods, as long as the requirements are met.

[0076] In some embodiments, such as Figure 3 As shown, there is a first preset distance between the forward propulsion blade 13 disposed on the rotating shaft 12 and the cylinder wall; there is a second preset distance between the stirring rod 14 disposed on the rotating shaft 12 and the cylinder wall; and there is a third preset distance between the end of the damping rod 15 away from the cylinder wall and the rotating shaft 12.

[0077] Specifically, there are gaps between the forward propulsion blade 13 and the cylinder wall, between the stirring rod 14 and the cylinder wall, and between the damping rod 15 and the rotating shaft 12. This allows the rotating shaft 12 to rotate normally and prevents it from getting stuck. Furthermore, the first, second, and third preset distances cannot be set too large; otherwise, sufficient contact between the material and the forward propulsion blade 13, stirring rod 14, and damping rod 15 will not be achieved.

[0078] In some embodiments, such as Figure 3 As shown, the rotating shaft 12 further includes a reverse propulsion section 22, which is located between the discharge section 21 and the second end A2 of the granulation cylinder 11; the granulation structure further includes a reverse propulsion blade 18; the reverse propulsion blade 18 is disposed on the reverse propulsion section 22; the reverse propulsion blade 18 includes two blades, and the extension directions of the two blades are perpendicular to each other; the reverse propulsion blade 18 on the reverse propulsion section 22 includes two reverse propulsion blade halves disposed opposite to each other on the reverse propulsion section 22.

[0079] Specifically, in order to prevent the material passing through the discharge section 21 from accumulating at the end cap 24 of the second end A2 of the granulation cylinder 11, this embodiment provides a rotating shaft 12 including a reverse propulsion section 22, on which two reverse propulsion blades 18 are provided. Through the action of the reverse propulsion blades 18, the material can be prevented from accumulating at the end cap 24 of the second end A2 of the granulation cylinder 11.

[0080] For example, such as Figure 3 At the location of the rotating shaft 12 currently shown, two anti-propulsion blades 18 are arranged for the anti-propulsion section 22. One anti-propulsion blade 18 extends in a direction parallel to X1, while the other anti-propulsion blade 18 extends in a direction perpendicular to X1. As the rotating shaft 12 rotates, the extending directions of the two anti-propulsion blades 18 change, but they remain perpendicular. Each anti-propulsion blade 18 comprises two anti-propulsion blade halves positioned opposite each other on the rotating shaft 12.

[0081] In some embodiments, such as Figure 2 As shown, the drive assembly includes a motor 26, a drive wheel 28, a conveyor belt 27, and a driven wheel 29;

[0082] The output shaft of the motor 26 is connected to the driving wheel 28, and the driven wheel 29 is connected to the rotating shaft 12. The driving wheel 28 and the driven wheel 29 are connected by a conveyor belt 27. Thus, when the granulator 10 is working, the driving assembly can provide driving force to it, that is, drive the rotating shaft 12 to rotate.

[0083] In some embodiments, combined with Figures 1 to 3The granulator 10 also includes a housing 32, the main body of the granulator 10 is disposed inside the housing 32, the housing 32 is provided with a feeding opening structure 30 corresponding to the feeding port 16, and the housing 32 is provided with a discharge cabinet door 31 corresponding to the discharge port 17.

[0084] Specifically, materials are manually fed in through the feeding opening structure 30. The materials enter the granulation cylinder 11 through the feed inlet 16. After being processed in the granulation cylinder 11, the materials come out through the discharge outlet 17 of the granulation cylinder 11 and are then successfully removed through the discharge cabinet door 31 to obtain the required granules.

[0085] In some embodiments, such as Figure 2 As shown, the granulation cylinder 11 has an inspection hole (not shown in the figure), which can also be called a manhole. The inspection hole facilitates installation and cleaning of the internal structure of the granulation cylinder 11.

[0086] In some embodiments, combined with Figure 2 and Figure 3 The first damping rod 15 disposed between the first processing section 201 and the wall of the granulation cylinder 11 can be in multiple sets. For example, four sets are disposed, with two sets disposed at the top of the cylinder wall and two sets disposed at the bottom of the cylinder wall, each set including seven rods.
