Description

Technical Field

[0001] This invention belongs to the field of granulation equipment technology, and specifically relates to a granulator. Background Technology

[0002] Granulation is a process that uses certain measures to process fine powder into larger granular materials. It transforms powder into granules by changing the physical form of the material. A granulator is the equipment that realizes the above granulation process.

[0003] Existing granulators typically include a rotatable cylinder. One end of the cylinder serves as the powder injection end, and the other end as the outlet end. When the powder is injected, some granules are added to the powder as granulation nuclei. After continuous material injection and stable cylinder rotation, the material accumulates inside the cylinder and forms an inclined slope. This inclined slope serves as the granulation interface. The granules, acting as nuclei, roll and combine with the powder on the slope to grow into granules, forming the desired granular material. During the granulation process, some of the formed granules break down and decompose as the cylinder rotates, forming new nuclei, thus continuing the granulation process and achieving granulation.

[0004] However, the inclined slope formed during the granulation process of existing granulators is uncontrollable and the slope is unstable, which leads to uneven rolling speed of the mother core, thus affecting the quality of the formed particles and making it impossible to control the particle size. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a granulator with an inclined granulation plate inside the cylinder. The inclined surface of the granulation plate serves as the granulation interface, allowing the nucleus to roll smoothly and evenly on the inclined surface of the granulation plate, thereby improving the quality of the particles. The granulation plate can be adjusted in terms of its inclination angle to control the rolling speed of the particles, which affects the granulation time and thus allows for the adjustment of particle size parameters.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A granulator comprising a rotatable cylinder; The cylinder is rotatably sealed at one end and has a feeding mechanism, while the other end of the cylinder is rotatably sealed and has a discharging mechanism. A support shaft is provided between the feeding mechanism and the discharging mechanism, and an inclined granulation plate is provided on the support shaft. The granulation plate is located inside the cylinder. The inner wall of the cylinder is provided with a feeding mechanism that can deliver granules and powders to the upper surface of the granulation plate.

[0007] Preferably, the feeding mechanism includes several sets of feeding components arranged along the circumference of the cylinder, and each set of feeding components includes several buckets distributed along the spiral direction on the inner wall of the cylinder.

[0008] Preferably, the bucket includes a fixed bucket that is fixedly connected to the inner wall of the cylinder, and a movable bucket is movably connected to the side of the fixed bucket away from the inner wall of the cylinder; As the bucket rotates with the cylinder, the movable bucket can move to close the outlet of the fixed bucket or move to open the outlet of the fixed bucket.

[0009] Preferably, the fixed hopper includes two first side plates that are parallel to each other along the axial direction of the cylinder and are fixedly connected to the inner wall of the cylinder, and one end of the two first side plates is fixedly connected by a hopper end plate; As the bucket rotates with the cylinder, the movable bucket can move to one end pressing against the bucket end plate to close the fixed bucket outlet, or the movable bucket can move to one end away from the bucket end plate to open the fixed bucket outlet.

[0010] Preferably, the movable hopper is rotatably engaged with the two first side plates via a rotating shaft; The rotating shaft divides the movable hopper into two parts: a first part closer to the hopper end plate and a second part farther away from the hopper end plate. The torque value of the first part of gravity is greater than the torque value of the second part of gravity.

[0011] Preferably, the granulation plate is provided with an outlet channel for introducing granular material into the discharge mechanism at one end near the discharge mechanism. The inlet of the outlet channel is located at the high end of the granulation plate, and the outlet of the outlet channel faces the discharge mechanism. The bucket near the discharge mechanism serves as the discharge hopper to deliver granular materials from inside the cylinder to the outlet channel.

[0012] Preferably, the granulation plate and the support shaft are connected by a number of connecting components; The connecting assembly includes a clamp for connecting to a support shaft, the clamp having a connecting seat, the top of which is connected to the granulation plate.

[0013] Preferably, the feeding mechanism includes a feeding cylinder that rotates and seals with the cylinder body, and a feeding end plate is coaxially fixedly disposed on the inner side of the feeding cylinder; The feed end plate is provided with a feed port.

[0014] Preferably, the discharge mechanism includes a discharge cylinder that rotates and seals with the cylinder body, and a discharge end plate is coaxially fixed at the end of the discharge cylinder away from the cylinder body; A conical screen plate is coaxially arranged on the inner side of the discharge cylinder. The large end of the conical screen plate faces the discharge end plate, and the small end of the conical screen plate is coaxially fixedly connected to the cylinder body. The discharge cylinder is provided with a first discharge port at the bottom of the conical screen plate, and a second discharge port is provided at the bottom of the discharge cylinder between the large end of the conical screen plate and the discharge end plate.

[0015] Preferably, a rolling ring is coaxially fixed on the outer wall of the cylinder, and the rolling ring is connected to a support drive mechanism used to support the cylinder and drive the cylinder to rotate.

[0016] The beneficial effects of this invention are: (1) The present invention introduces an inclined granulation plate inside the cylinder. The inclined surface of the granulation plate serves as the granulation interface, allowing the mother nucleus to roll smoothly and evenly on the inclined surface of the granulation plate and combine evenly with the powder, thereby improving granulation efficiency and particle quality.

[0017] (2) The present invention introduces a bucket into the cylinder to realize the separation of granules and powders. The granules are fed to the granulation plate and roll along the granulation plate, while the powders are sprinkled on the granulation plate. As the cylinder continues to rotate, the powders are continuously and evenly sprinkled on the granulation plate and the granules continue to roll and grow into granules on the granulation plate, which increases the probability and frequency of contact between the granules and the powders, thereby improving the granulation efficiency.

[0018] (3) Before using this invention, the installation tilt angle of the granulation plate is first adjusted by rotating the support shaft to control the rolling speed of the particles, which affects the granulation time and thus achieves the adjustment of the particle size index.

An inclined granulation plate 5 is provided on the support shaft 4, and the granulation plate 5 is located inside the cylinder 1. The central axis of the support shaft 4 is parallel to the central axis of the cylinder 1. The inner wall of the cylinder 1 is provided with a feeding mechanism that can deliver granules and powders to the upper surface of the granulation plate 5.

[0027] Preferably, the feeding mechanism includes several sets of feeding components arranged along the circumference of the cylinder 1, and each set of feeding components includes several buckets 6 distributed along a spiral direction on the inner wall surface of the cylinder 1. The feeding mechanism shown in the attached figures includes four sets of feeding components arranged along the circumference of the cylinder 1, and each set of feeding components includes six buckets 6 distributed along a spiral direction on the inner wall surface of the cylinder 1.

[0028] Preferably, the bucket 6 includes a fixed bucket 61 that is fixedly connected to the inner wall of the cylinder 1, and a movable bucket 62 is movably connected to the side of the fixed bucket 61 away from the inner wall of the cylinder 1. As the bucket 6 rotates with the cylinder 1, the movable bucket 62 can move to close the outlet of the fixed bucket 61 or move to open the outlet of the fixed bucket 61.

[0029] According to the rotation direction of the cylinder 1, the inlet of the fixed hopper 61 is located at the front end of the excavator 6.

[0030] Preferably, the fixed hopper 61 includes two first side plates 611 that are parallel to each other along the axial direction of the cylinder 1 and fixedly connected to the inner wall of the cylinder 1.

[0031] When the movable hopper 62 moves to the point where one end presses against the hopper end plate 612, the other end of the movable hopper 62 forms an inlet for the fixed hopper 61 between the two first side plates 611 and the inner wall of the cylinder 1.

[0032] Preferably, the movable hopper 62 is rotatably engaged with the two first side plates 611 via a rotating shaft 63; The rotating shaft 63 divides the movable hopper 62 into two parts: a first part 621 near the hopper end plate 612 and a second part 622 away from the hopper end plate 612. The torque value of the first part 621 gravity is greater than the torque value of the second part 622 gravity.

[0036] Preferably, the granulation plate 5 is provided with an outlet channel 51 for introducing granular materials into the discharge mechanism 3 at one end near the discharge mechanism 3. The inlet of the outlet channel 51 is located at the high end of the granulation plate 5, and the outlet of the outlet channel 51 faces the discharge mechanism 3. The bucket 6, located near the discharge mechanism 3, serves as the discharge hopper for conveying granular materials from the cylinder 1 to the outlet channel 51.

[0037] Preferably, the granulation plate 5 and the support shaft 4 are connected by a plurality of connecting components 52; The connecting component 52 includes a clamp 521 for connecting to the support shaft 4, and a connecting seat 522 is provided on the clamp 521. The top end of the connecting seat 522 is connected to the granulation plate 5.

[0038] Preferably, the feeding mechanism 2 includes a feeding cylinder 21 that is rotatably and sealingly fitted with the cylinder body 1, and a feeding end plate 22 is coaxially and fixedly disposed on the inner side of the feeding cylinder 21; specifically, a feeding annular end plate 12 is coaxially and fixedly disposed on one axial end of the cylinder body 1, and the feeding cylinder 21 is rotatably and sealingly fitted on the radial inner side of the feeding annular end plate 12. The feed end plate 22 is provided with a feed port 23. One end of the support shaft 4 is sealed and fitted onto the feed end plate 22.

[0039] Preferably, the discharge mechanism 3 includes a discharge cylinder 31 that rotates and seals with the cylinder body 1, and a discharge end plate 32 is coaxially fixed at the end of the discharge cylinder 31 away from the cylinder body 1. A conical screen plate 33 is coaxially arranged on the inner side of the discharge cylinder 31. The large end of the conical screen plate 33 faces the discharge end plate 32, and the small end of the conical screen plate 33 is coaxially fixedly connected to the cylinder 1. Specifically, a discharge annular end plate 13 is coaxially fixedly arranged on the other axial end of the cylinder 1. The discharge cylinder 31 and the outer axial end of the discharge annular end plate 13 are rotated and sealed. The small end of the conical screen plate 33 is fixedly connected to the radial inner side of the discharge annular end plate 13. The discharge cylinder 31 is provided with a first discharge port 34 at the bottom of the conical screen plate 33, and a second discharge port 35 is provided at the bottom of the discharge cylinder 31 between the large end of the conical screen plate 33 and the discharge end plate 32.

[0040] Preferably, a rolling ring 11 is coaxially fixed on the outer wall of the cylinder 1, and the rolling ring 11 is connected to a support drive mechanism used to support the cylinder 1 and drive the cylinder 1 to rotate.

[0041] Specifically, the support drive mechanism includes rollers 7 supported on both sides of the lower part of the rolling ring 11. The rollers 7 are connected to a drive mechanism used to drive their rotation. The drive mechanism can be implemented using existing technology, and will not be described in detail here.

[0042] A granulator, the specific implementation of which is as follows: Before use, the installation tilt angle of the granulation plate 5 is first adjusted by rotating the support shaft 4, which in turn adjusts the rolling speed of the granules, which serve as the core, on the granulation plate 5, affecting the granulation time and thus adjusting the particle size index. Then, both ends of the support shaft 4 are fixed to the corresponding brackets.

[0043] During operation, the cylinder 1 is rotated, and powdery material containing the mother nucleus is injected through the feed inlet 23. As the powdery material is continuously injected and the granular material is continuously discharged, once the operation is stable, the material inside the cylinder 1 accumulates at the lower part of the granulation plate 5. The content of powdery material gradually decreases and the content of granular material gradually increases along the direction from the feed mechanism 2 to the discharge mechanism 3. As the bucket 6 rotates with the cylinder 1, when the bucket 6 inserts into the accumulated material from top to bottom, the movable bucket 62 digs out the material with more granules, such as the mother nucleus and granular material, located at the top, while the fixed bucket 61 digs out... The lower part contains more powder material, thus achieving the separation of powder and granules; after the excavator bucket 6 digs out the material, as it rotates upward to the top, the material containing more granules on the movable bucket 62 first falls onto the granulating plate 5 and rolls along the granulating plate 5, combining with the powder on the granulating plate 5 to grow into granules. Then, the powder on the fixed bucket 61 is evenly sprinkled onto the granulating plate 5 as the position of the excavator bucket 6 changes and the outlet of the fixed bucket 61 is opened; with the continuous rotation of the cylinder 1, the powder is continuously and evenly sprinkled onto the granulating plate 5 and the granules are continuously rolled and grown into granules on the granulating plate 5. The bucket 6, which serves as the discharge hopper, scoops up the granular material near the end of the discharge mechanism 3 and transports it to the inlet of the outlet channel 51. It is then transported to the conical screen plate 33 through the outlet of the outlet channel 51. After being screened by the conical screen plate 33, the granular material that meets the screen hole requirements is discharged from the first discharge port 34, while the granular material that does not meet the screen hole requirements is discharged from the second discharge port 35.

[0044] While the specific embodiments of the present invention have been described above in conjunction with the accompanying drawings, they are not intended to limit the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of the present invention are still within the protection scope of the present invention.
