DETAILED DESCRIPTION

[0036] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the scheme of the present invention will be further described below. It should be noted that, in the absence of conflict, the embodiments of the present invention and the features therein can be combined with each other.

[0037] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present invention, rather than all the embodiments.

[0038] The granulator provided by the embodiment of the present invention is provided with a positive propulsion blade and a stirring rod during the rotation of the shaft, and a damping rod is provided between the wall of the granulation barrel and the rotation of the shaft. When the material enters the granulation barrel, it enters the processing section under the action of the positive propulsion blade. The material at the processing section is stirred, kneaded, sheared, extruded, etc. under the action of the stirring rod, the damping rod and the rotation of the rotating shaft to form uniform round particles. After that, the round particles enter the position of the discharge section. The round particles are discharged from the discharge port under the action of the stirring rod, thereby realizing the recycling of tailings or sludge, etc., and obtaining particles that meet the needs. Therefore, the granulator provided by the embodiment of the present invention can change the kneading, shearing, extrusion and other forces for different tailings or sludge, etc., so as to achieve round particles that meet the requirements, and can achieve a large production capacity of continuous feeding and discharging.

[0039] The granulator provided by the embodiment of the present invention is exemplarily described below with reference to the accompanying drawings.

[0040] Figure 1 A schematic structural diagram of a granulator provided in an embodiment of the present invention is shown. Figure 2 This is a structural diagram of a granulator without a shell provided by an embodiment of the present invention. Figure 3 This is a schematic diagram of the structure of a granulation component provided by an embodiment of the present invention. It should be noted that in order to clearly show 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 bracket 23; the granulation assembly 33 includes a granulation cylinder 11 and a granulation structure, and the granulation cylinder 11 is fixedly arranged on the bracket 23 in the horizontal direction; the granulation structure includes a rotating shaft 12, a forward propulsion blade 13, a stirring rod 14 and a damping rod 15; the rotating shaft 12 is arranged in the horizontal direction inside the granulation cylinder 11, and end caps 24 are provided at both ends of the granulation cylinder 11. A through hole is provided at the center of the end cap 24, and both ends of the rotating shaft 12 extend through the through hole;

[0042] The granulation cylinder 11 is provided with a feed port 16 and a discharge port 17 on its wall. The feed port 16 is located at the top end of the granulation cylinder 11 and is adjacent to the first end A1 of the granulation cylinder 11. The discharge port 17 is located at the bottom end 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 driving assembly.

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

[0044] The processing section 20 includes a first processing section 201; the stirring rod 14 is arranged at a preset distance on the first processing section 201, and a first damping rod 151 is arranged between the first processing section 201 and the cylinder wall of the granulation cylinder 11. The first damping rod 151 is arranged at a preset distance along the direction of the rotating shaft 12, and one end of the first damping rod 15 is located on the cylinder wall.

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

[0046] Specifically, when the granulator 10 is in operation, the drive assembly provides driving force to the granulation assembly 33, causing the rotary shaft 12 to rotate at high speed. Material, such as tailings or sludge, is fed into the granulation drum 11 through the loading opening 30 provided on the housing 32 and the feed port 16 provided on the wall of the granulation drum 11. The material enters the feed section 19 and, under the action of the forward propulsion blades 13 provided on the feed section 19, propels the material 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 rotation of the rotating shaft 12, the material at the first processing section 201 is stirred, kneaded, sheared, extruded, etc. to form uniform round particles, and then enters the position of 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 renewable utilization of tailings or sludge, etc., and obtaining particles that meet the needs.

[0047] The granulator provided by the embodiment of the present application is provided with positive propulsion paddles and stirring rods through the rotation of the shaft, and is provided with damping rods between the shaft rotation and the cylinder wall of the granulation cylinder. When the material enters the granulation cylinder, the material enters the processing section under the action of the positive propulsion paddles. The material at the position of the processing section is stirred, kneaded, sheared, extruded and the like under the action of the stirring rods, the damping rods and the rotation of the rotating shaft, to form uniform circular particles. Then, the circular particles enter the position of the discharging section, and the circular particles are discharged from the discharge port under the action of the stirring rods, so that the tailings or sludge and the like can be recycled to obtain particles meeting the requirements. Therefore, the granulator provided by the embodiment of the present application can change the strength of kneading, shearing and extruding for different tailings or sludge and the like, so that the circular particles meeting the requirements can be obtained, and the large capacity of continuous feeding and discharging can be realized.

[0048] In some embodiments, as shown in Figure 3 The processing section 20 further includes a second processing section 202 and a third processing section 203, and the first processing section 201, the second processing section 202 and the third processing section 203 are sequentially arranged.

[0049] The positive propulsion paddles 13 are arranged on the second processing section 202, the stirring rods 14 are arranged on the third processing section 203 at a preset distance, the second damping rods 152 are arranged between the third processing section 203 and the cylinder wall of the granulation cylinder 11, the second damping rods 152 are arranged at a preset distance along the direction of the rotating shaft 12, and one end of the second damping rods 152 is located on the cylinder wall.

[0050] Specifically, when the viscosity of the material such as sludge is large, in order to better obtain uniformly dispersed particles, the embodiment of the present application is arranged with the second processing section 202 and the third processing section 203 on the basis of the first processing section 201.

[0051] The positive propulsion paddles 13 are arranged on the second processing section 202, and the material treated by the first processing section 201 can advance to the third processing section 203 under the action of the positive propulsion paddles 13. The stirring rods 14 and the second damping rods 152 are correspondingly arranged at the third processing section 203, and the material at the third processing section 203 is stirred, kneaded, sheared, extruded and the like under the action of the stirring rods 14, the second damping rods 152 and the rotation of the rotating shaft 12 to form uniform circular particles. Therefore, the material is treated by the third processing section 203 on the basis of the treatment of the material by the first processing section 201 in the embodiment of the present application. When the viscosity of the material such as sludge is large, uniformly dispersed particles can be obtained, so as to meet the requirements.

[0052] In some embodiments, as shown in Figure 3As shown, the two positive propulsion paddles 13 on the second processing section 202 are arranged in directions perpendicular to each other.

[0053] The two positive propulsion paddles 13 on the second processing section 202 are arranged in two positive propulsion paddle halves opposite to the rotating shaft 12.

[0054] Specifically, two positive propulsion paddles 13 are arranged at a preset distance on the second processing section 202 of the rotating shaft 12, each of which includes two positive propulsion paddle halves opposite to the second processing section 202, and the two positive propulsion paddles 13 are arranged in directions perpendicular to each other. Thus, during rotation of the rotating shaft 12, the positive propulsion paddles 13 can be in full contact with the material and push the material to the third processing section 203.

[0055] Exemplarily, as Figure 3 Currently, the two positive propulsion paddles 13 on the rotating shaft 12 are arranged in directions parallel to the X1 direction and directions perpendicular to the X1 direction. During rotation of the rotating shaft 12, the directions of the two positive propulsion paddles 13 change, but are always perpendicular. The positive propulsion paddles 13 include two positive propulsion paddle halves opposite to the rotating shaft 12.

[0056] It should be noted that according to the actual granulation result, two positive propulsion paddles 13 on the second processing section 202 are sufficient, and one positive propulsion paddle 13 cannot meet the granulation effect, and more positive propulsion paddles 13 do not have a difference in granulation effect.

[0057] In some embodiments, as Figure 3 As shown, the two positive propulsion paddles 13 on the second processing section 202 are arranged in directions perpendicular to each other.

[0058] Specifically, a plurality of stirring rods 14 can be arranged at predetermined 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 the stirring rods in one group perpendicular to the extension direction of the stirring rods in the other group, and the extension directions of two 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 the material. Simultaneously, in combination with the second damping rod 152 disposed between the third processing section 203 and the wall of the granulating drum 11, the material in the third processing section 203 is stirred, kneaded, sheared, extruded, etc., under the action of the rotation of the stirring rods 14, the second damping rod 152, and the rotating shaft 12, to form uniform round granules.

[0059] For example, Figure 3 The currently shown position of the rotating shaft 12 corresponds to the two sets of stirring rods installed on the third processing section 203. One set of stirring rods extends parallel to the X1 direction, while the other set extends perpendicular to the X1 direction. As the rotating shaft 12 rotates, the extension directions of the two sets of stirring rods change, but remain perpendicular. Each stirring rod 14 on the third processing section 203 consists of two stirring rod halves positioned opposite the rotating shaft 12.

[0060] For example, 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. The embodiment of the present invention does not specifically limit the number of stirring rods to be set, and it is sufficient to meet the needs.

[0061] In some embodiments, as Figure 3 As shown, the positive propulsion blades 13 on the feeding section 19 include two groups of positive propulsion blades 13. The extension direction of one group of positive propulsion blades 13 is perpendicular to the extension direction of the other group of positive propulsion blades 13. The extension directions of two adjacent positive propulsion blades 13 are different.

[0062] The forward propulsion blade 13 on the feed section 19 includes two forward propulsion blade halves arranged opposite to each other on the rotating shaft 12 .

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

[0064] For example, Figure 3 The current position of the rotating shaft 12 is shown. For the two sets of forward propulsion blades installed on the feed section 19, one set of forward propulsion blades extends parallel to the X1 direction, while the other set of forward propulsion blades extends perpendicular to the X1 direction. 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 installed on the feed section 19 comprises two forward propulsion blade 13 halves positioned oppositely from the rotating shaft 12.

[0065] For example, Figure 3 As shown, six positive propulsion blades 13 can be set on the feed section 19. The six positive propulsion blades 13 are divided into two groups of positive propulsion blades, and each group of positive propulsion blades includes three positive propulsion blades 13. The embodiment of the present invention does not specifically limit the number of settings, as long as the needs are met.

[0066] In some embodiments, as Figure 3 As shown, the stirring rods 14 on the first processing section 201 include two groups of stirring rods, and the extending direction of one group of stirring rods is perpendicular to the extending direction of the other group of stirring rods; the extending 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 arranged opposite to each other on the rotating shaft 12 .

[0068] Specifically, a plurality of stirring rods 14 can be arranged at predetermined 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 the stirring rods in one group perpendicular to the extension direction of the stirring rods in the other group, and the extension directions of two 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 the material. Simultaneously, in combination with the plurality of first damping rods 151 disposed between the first processing section 201 and the wall of the granulating drum 11, the material in the first processing section 201 is stirred, kneaded, sheared, extruded, etc., under the action of the rotation of the stirring rods 14, the first damping rods 151, and the rotating shaft 12, to form uniform round granules.

[0069] For example, Figure 3 The currently shown position of the rotating shaft 12 corresponds to the two sets of stirring rods installed on the first processing section 201. One set of stirring rods extends parallel to the X1 direction, while the other set of stirring rods extends perpendicular to X1. As the rotating shaft 12 rotates, the extension directions of the two sets of stirring rods change, but remain perpendicular. Each stirring rod 14 installed on the first processing section 201 consists of two stirring rod halves positioned opposite the rotating shaft 12.

[0070] For example, 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. The embodiment of the present invention does not specifically limit the number of stirring rods to be set, and it is sufficient to meet the needs.

[0071] In some embodiments, as Figure 3 As shown, the stirring rods 14 on the discharge section 21 include two groups of stirring rods, and the extending direction of one group of stirring rods is perpendicular to the extending direction of the other group of stirring rods; the extending directions of two adjacent stirring rods 14 are different;

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

[0073] Specifically, a plurality of stirring rods 14 are disposed at predetermined intervals on the discharge section 21 of the rotating shaft 12. The stirring rods 14 are divided into two groups, with the stirring rods in one group extending perpendicularly to the other, and adjacent stirring rods 14 extending in different directions. Thus, the stirring rods 14 facilitate shaking out the material from the discharge port 17 to obtain particles that meet the requirements.

[0074] For example, Figure 3 The current position of the rotating shaft 12 is shown for the 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 extension directions of the two sets of stirring rods change, but remain perpendicular. Each stirring rod 14 comprises two stirring rod halves positioned opposite each other on the rotating shaft 12.

[0075] For example, 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. The embodiment of the present invention does not specifically limit the number of stirring rods to be set, and it is sufficient to meet the needs.

[0076] In some embodiments, as Figure 3 As shown, there is a first preset distance between the forward propulsion blade 13 set on the rotating shaft 12 and the cylinder wall; there is a second preset distance between the stirring rod 14 set on the rotating shaft 12 and the cylinder wall; 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 is a gap between the forward propulsion blade 13 and the cylinder wall, a gap between the stirring rod 14 and the cylinder wall, and a gap between the damping rod 15 and the rotating shaft 12, which enables the rotating shaft 12 to rotate normally and prevents the rotating shaft 12 from getting stuck. In addition, the first preset distance, the second preset distance, and the third preset distance cannot be set too large. If they are set too large, sufficient contact between the material and the forward propulsion blade 13, the stirring rod 14, and the damping rod 15 cannot be achieved.

[0078] In some embodiments, as Figure 3 As shown, the rotating shaft 12 also includes a reverse propulsion section 22, and the reverse propulsion section 22 is located between the discharge section 21 and the second end A2 of the granulation cylinder 11; the granulation structure also includes a reverse propulsion blade 18; the reverse propulsion blade 18 is arranged on the reverse propulsion section 22; the reverse propulsion blade 18 includes two, and the extension directions of the two reverse propulsion blades 18 are perpendicular to each other; the reverse propulsion blade 18 on the reverse propulsion section 22 includes two reverse propulsion blade halves relatively arranged 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 cover 24 of the second end A2 of the granulation cylinder 11, the present embodiment provides the rotating shaft 12 with a reverse propulsion section 22, and two reverse propulsion blades 18 are provided on the reverse propulsion section 22. Through the action of the reverse propulsion blades 18, the material can be prevented from accumulating at the end cover 24 of the second end A2 of the granulation cylinder 11.

[0080] For example, Figure 3 In the illustrated position of the rotating shaft 12, two reverse propulsion blades 18 are provided for the reverse propulsion section 22. One reverse propulsion blade 18 extends parallel to the X1 direction, while the other reverse propulsion blade 18 extends perpendicular to the X1 direction. As the rotating shaft 12 rotates, the directions of the two reverse propulsion blades 18 change, but remain perpendicular. Each reverse propulsion blade 18 comprises two reverse propulsion blade halves positioned oppositely from the rotating shaft 12.

[0081] In some embodiments, as Figure 2 As shown, the driving assembly includes a motor 26, a driving 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. Therefore, when the granulator 10 is working, the driving assembly can provide driving force to it, that is, drive the rotating shaft 12 to rotate.
