Description

Technical Field

[0001] This utility model relates to the field of granulator technology, and in particular to a granulator. Background Technology

[0002] A granulator is a mechanical device used to process powdery or granular materials into spherical, cylindrical, or other shaped particles. It is widely used in the chemical, pharmaceutical, food, feed, and fertilizer industries to produce various granular products. The working principle of a granulator is generally to compact and shape the material using mechanical force, thereby achieving particle manufacturing.

[0003] Granulators are very important pieces of machinery that can process powdery or granular materials into granules of various shapes. They are widely used in many industries, as illustrated by the existing technology, Chinese patent publication number "CN219441567U". A granulator is provided, including a granulator body, a feeding hood at the top of the granulator body, a feeding pipe vertically mounted on the top of the feeding hood, a feeding hopper at the top of the feeding pipe, and interconnections between the feeding hopper and the feeding pipe, as well as between the feeding pipe and the feeding hood. Guide plates are mounted on both sides inside the feeding pipe, and a buffer assembly is installed between the guide plates and the inner wall of the feeding pipe. A guide component is installed inside the feeding hood. A motor is installed inside the granulator body. When traditional Chinese medicine falls into the feeding hood via the guide component, the medicine material falls into a receiving cavity for temporary storage. The motor and reducer drive a rotating shaft to rotate, thereby rotating the guide component and pushing the medicine to the feeding port, where it falls into the granulator body. This avoids material accumulation, prevents blockage, improves work efficiency, and allows for easy control of the rotation speed of the guide component, thus controlling the amount of traditional Chinese medicine fed.

[0004] Currently, most roller-type wet granulation machines require manual opening of the cover to remove the material after granulation, as they are horizontally fixed. If there are many particles, the removal process will take a lot of time. Therefore, a granulation mechanism that can be adjusted according to the start and discharge process is needed to facilitate the operation of workers and save discharge time. Utility Model Content

Then, the powder raw material is fed into the material cylinder through the feed port. Then, the power of the second motor is turned on, so that the second shaft of the second motor can rotate the second shaft, thereby driving the drum to rotate. Then, through external water supply, the spray pipe can be injected with medicine or clean water, which is sprayed out through the nozzle to wet the raw material.

The motor 15 has a drive shaft inside. A drive pulley 16 is fixedly sleeved at the end of the drive shaft. A linkage pulley 14 is fixedly sleeved at the outer end of the shaft 13. The linkage pulley 14 and the drive pulley 16 are connected by a belt 17. The motor 15 is not directly connected to the drive pulley 16, which can avoid damage to the motor 15 due to the excessive weight of the feed material in the material cylinder 111.

[0029] A positioning plate 18 is provided above the side platform 11. One end of the positioning plate 18 is fixedly assembled to the top of the side platform 11 by screws.

The threaded sleeve 19 has a threaded knob 110 inside. Several threaded seats 112 are provided on the surface of the shaft 13. One end of the threaded seat 112 is welded to the surface of the shaft 13. There are at least four threaded seats 112, and the threaded seats 112 are evenly distributed along the surface of the shaft 13. The lower end of the threaded knob 110 is threadedly connected to any one of the threaded seats 112. When the material cylinder 111 is placed horizontally, the horizontal placement and reinforcement of the material cylinder 111 can be achieved by the threaded knob 110 cooperating with the corresponding threaded seat 112, thereby ensuring the stable operation of the granulation process.

[0030] It should be further explained that a bearing 2 is installed through the center of the closed end of the barrel 111.

The waste discharge port 23 can discharge waste liquid and waste material when the waste material is discharged through the through hole 25 and the waste material is between the material cylinder 111 and the drum 26 during the rinsing process. There are two sets of waste discharge ports 23, which are symmetrically distributed along the closed end of the material cylinder 111.

[0034] It should be further explained that the open end of the material cylinder 111 is covered with a cover plate 3. The inward side of the cover plate 3 is fitted to the open end of the roller 26.

[0035] It should be further explained that a spray pipe 32 is provided through the surface of the cover plate 3. The connection between the spray pipe 32 and the cover plate 3 is fixed by welding. Several nozzles 33 are provided through the surface of the spray pipe 32. The connection between the nozzles 33 and the spray pipe 32 is fixed by welding. The spray pipe 32 is connected to an external water pump through a hose. During granulation, it can deliver liquid medicine or clean water, so that the powdered raw material can become moist and clump together to form granulated material.

[0036] It should be further noted that a feed inlet 34 is also provided through the surface of the cover plate 3. The feed inlet 34 is fixed to the cover plate 3 by welding. A sealing plug 35 is inserted inside the cover plate 3. The sealing plug 35 and the feed inlet 34 are threaded together. The feed inlet 34 can convey powder raw materials. The outer ring wall of the sealing plug 35 is provided with external threads, and the inner ring wall of the feed inlet 34 is provided with internal threads. The external threads and internal threads are threaded together. A knob is fixed to the outward end of the sealing plug 35. The knob can facilitate the rotation operation of the sealing plug 35.

[0037] Working method: When granulation is required, the first motor 15 drives the first shaft to rotate the drive pulley 16. Through the transmission effect of the belt 17, the first shaft 13 rotates. The two shafts 13 on both sides cooperate to drive the material cylinder 111 to a horizontal position. Then, to ensure the stability of the material cylinder 111, the threaded knob 110 is connected to the threaded sleeve 19 and the corresponding threaded seat 112. The threaded engagement ensures the stable horizontal placement of the material cylinder 111. Then, the powder raw material is fed into the material cylinder 111 through the feed port 34. Then, the power of the second motor 22 is turned on, so that the second shaft of the second motor 22 can rotate the second shaft 21, thereby driving the drum 26 to rotate. Then, through external water supply, the spray pipe 32 can be injected with medicine or clean water, which is sprayed out through the nozzle 33 to wet the raw material. Through the continuous rotation of the drum 26 and the continuous impact of the material with the protrusion 24 to form a granular structure, stable granulation can be achieved.

[0038] After granulation, first rotate the threaded knob 110 to separate it from the threaded sleeve 19 and the threaded seat 112 respectively, which can restore the normal rotation of the shaft 13. Driven by the motor 15, and with the transmission of the two pulleys and the belt 17, the shaft 13 can rotate the material cylinder 111, so that the opening of the material cylinder 111 can be tilted downward, which facilitates the overall discharge. The piston rod of the cylinder 31 pushes the cover plate 3 to gradually open, so that the semi-finished product that has been initially granulated can be directly discharged, saving time and improving efficiency.
