Description

A wet granulator with fast discharging Technical Field

[0001] The invention relates to the technical field of wet granulators, in particular to a wet granulator with rapid discharge. Background Art

[0002] Wet granulators are used for products such as pharmaceuticals, food, feed, and ceramics. To use, simply add the main and auxiliary ingredients to the blender in the appropriate proportions and formula. The powdered material and binder are then thoroughly mixed in a cylindrical container by a high-speed mixing paddle at the bottom, resulting in a wet, soft material. High-speed pulverizing paddles on the side then cut the material into uniform wet granules, achieving the desired granulation effect. To discharge material from existing wet granulators, the mixing paddles are first adjusted to a low-speed, gap-type rotation. The valve at the discharge port is then opened using a pneumatic cylinder, allowing the wet granules to flow out of the machine.

[0003] As in the prior art, the patent with patent authorization announcement number CN217490757U discloses a high-efficiency wet mixing granulator based on forward and reverse bidirectional rotation, including a base and a discharge pipe; the base: a stirring barrel is provided in the middle of its upper surface, a barrel cover is provided at the upper end opening of the stirring barrel, and a first hopper and a second hopper are respectively provided at the edge of the barrel cover, a granulating motor is installed through a flange at the bottom right end of the outer side surface of the stirring barrel, the output shaft of the granulating motor passes through the through hole at the lower right end of the stirring barrel and is provided with a granulating blade at the end head, and a stirring mechanism is provided inside the stirring barrel; a discharge pipe: provided at the discharge port at the bottom left end of the outer side surface of the stirring barrel, a baffle corresponding to the discharge port is slidably connected to the inside of the discharge pipe, the high-efficiency wet mixing granulator based on forward and reverse bidirectional rotation can quickly mix the materials through forward and reverse rotation, and the mixing is more uniform and thorough, and the particles can also be screened after granulation, thereby greatly improving the quality of the particles.

[0004] Although the granulator in the above patent can quickly mix the materials through forward and reverse rotation, and the mixing is more uniform and thorough, and the particles can be screened after granulation, thereby greatly improving the quality of the particles, however, when the existing granulator is discharging the materials, since the stirring paddle rotates at a low speed and intervals, the wet particles close to the axis of the stirring paddle are difficult to be moved to the discharge port by the stirring paddle, thereby causing the discharging speed of some wet particles to be slow, affecting production efficiency.

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] Please refer to Figures 1-10. A wet granulator with rapid discharge includes a granulator body 1. One end of the top of the granulator body 1 is fixedly connected to a tank body 2. A discharge port is opened on one side of the tank body 2. A discharge plate 201 is fixedly connected to the outside of the discharge port. A sealing component is fixedly connected to the inside of the discharge plate 201. A positioning sleeve 3 is fixedly connected to the bottom of the tank body 2. A driven gear 5 is rotatably connected to the bottom of the positioning sleeve 3. A driving gear 6 is meshed with one side of the driven gear 5. A motor 7 fixedly connected to the granulator body 1 is provided at the bottom of the driving gear 6. A connecting sleeve is fixedly connected to the inner wall of the output end of the motor 7 and the driving gear 6. Cylinder 8, the upper end of the connecting sleeve 8 is slidably connected to the agitator 10, and a lifting rod 12 is fixed to the center position of the inner side of the agitator 10. The lower end of the lifting rod 12 passes through the connecting sleeve 8 and is rotatably connected to the lifting assembly. A card slot 13 is provided at the lower end of the lifting rod 12, and a snap ring 18 is rotatably connected to the inside of the card slot 13. The top of the snap ring 18 is fixed to the plug rod 19, and a slot 20 matching the plug rod 19 is provided on the driven gear 5. The bottom of the inner side of the tank body 2 is rotatably connected to the bottom plate 21, and a socket 22 matching the plug rod 19 is provided at the bottom of the bottom plate 21. Adjacent sockets 22 are separated by partitions 23.

[0028] The wet granulator with fast discharge in the present invention, when discharging, first turn off the motor 7, then push the insertion rod 19 into the insertion hole 22 at the bottom of the bottom plate 21 through the lifting component, and open the discharge port through the sealing component, and then start the motor 7 again (the speed of the motor 7 at this time is different from the speed during granulation, and it is a low-speed rotation, suitable for unloading). The motor 7 will drive the driven gear 5 to rotate through the driving gear 6, and the driven gear 5 will drive the insertion rod 19 to rotate, and the insertion rod 19 will drive the bottom plate 21 to rotate, so that the bottom plate 21 and the agitator 10 can rotate together. The bottom plate 21 will generate centrifugal force when rotating, so that the wet particles in the tank body 2 will roll to the surroundings. The wet particles are at the top of the bottom plate 21, so they will rotate with the bottom plate 21 until the wet particles move to the discharge port. The wet particles are no longer blocked and will flow out directly from the discharge port. Under the action of centrifugal force, the wet particles will move faster to the edge of the tank body 2, making the discharge faster and more convenient. At the same time, the motor 7 belongs to the product of existing mature technology, so it will not be described in detail here. In addition, the structure of the granulator body 1 and the tank body 2 in the present invention is similar to the structure of the high-efficiency wet mixing granulator based on forward and reverse bidirectional rotation disclosed in the patent authorization announcement number CN217490757U, so it will not be elaborated on here.

[0029] As a preferred technical solution of the present invention, the lifting assembly includes a lifting cylinder 17, a push rod 15 and a rotating block 14. The bottom of the lifting cylinder 17 is fixedly connected to the granulator body 1, the output end of the lifting cylinder 17 is fixedly connected to the push rod 15, and a rotating groove 16 is provided on the top of the push rod 15. The internal rotation of the rotating groove 16 is connected to the rotating block 14, and the top of the rotating block 14 is fixedly connected to the bottom of the lifting rod 12.

[0030] Specifically, when the lifting cylinder 17 is started, the lifting cylinder 17 will push the push rod 15 to rise, and the push rod 15 will push the lifting rod 12 to move upward, so that the retaining ring 18 at the lower end of the lifting rod 12 drives the insertion rod 19 to move upward, thereby facilitating the insertion of the insertion rod 19 into the socket 22 at the bottom of the base plate 21. After that, when the motor 7 drives the driven gear 5 to rotate through the driving gear 6, the insertion rod 19 inserted in the slot 20 on the driven gear 5 will rotate accordingly, thereby driving the base plate 21 to rotate.

[0031] As a preferred technical solution of the present invention, the sealing component includes a sealing block 24 and a horizontal pushing cylinder 25. The horizontal pushing cylinder 25 is fixedly connected to one side of the outer wall of the discharge plate 201. The output end of the horizontal pushing cylinder 25 passes through the discharge plate 201 and extends to the interior of the discharge plate 201. The output end of the horizontal pushing cylinder 25 is fixedly connected to the sealing block 24, and the sealing block 24 is L-shaped.

[0032] Specifically, when the discharge port needs to be opened, it is only necessary to start the horizontal pushing cylinder 25. The horizontal pushing cylinder 25 will push the sealing block 24 to move into the tank body 2 (it should be noted here that the lifting height of the agitator 10 is greater than the height of the sealing block 24, so when the sealing block 24 is pushed into the tank body 2, it will not affect the agitator 10), thereby opening the discharge port.

[0033] As a preferred technical solution of the present invention, the inner side of the sealing block 24 is arc-shaped. The inner side of the arc-shaped setting is convenient for guiding the wet particles and making it easier for the wet particles to enter the discharge port.

[0034] As a preferred technical solution of the present invention, the outer wall of the connecting sleeve 8 is fixedly connected to the limit plate 9, and the inner wall of the agitator 10 is provided with a limit groove 11, which matches the limit plate 9. The connecting sleeve 8 is fixedly connected to the driven gear 5, and the connecting sleeve 8 and the agitator 10 are slidably connected via the limit plate 9 and the limit groove 11. Therefore, no matter what height the agitator 10 is at, when the driven gear 5 drives the connecting sleeve 8 to rotate, the connecting sleeve 8 will drive the agitator 10 to rotate through the limit plate 9, and the limit plate 9 prevents the agitator 10 from not rotating with the connecting sleeve 8, causing the agitator 10 to lose its stirring effect.

[0035] As a preferred technical solution of the present invention, the top of the insertion rod 19 and the bottom of the partition 23 are both tapered. The tapered setting makes it easier for the insertion rod 19 to be inserted into the insertion hole 22, and prevents the insertion rod 19 from being blocked by the partition 23, resulting in the insertion rod 19 being unable to be inserted into the interior of the insertion hole 22.

[0036] As a preferred technical solution of the present invention, a positioning groove 4 is formed at the top of the driven gear 5 to match the positioning sleeve 3. The cross-section of the lower end of the positioning sleeve 3 is L-shaped. The positioning sleeve 3 is located within the positioning groove 4, which facilitates the restraint of the driven gear 5. At the same time, the L-shaped positioning sleeve 3 has a better limiting effect.

[0037] In addition, it should be noted that the motor 7, lifting cylinder 17 and horizontal pushing cylinder 25 involved in the present invention are all products of existing mature technologies, so they will not be elaborated on in detail here, and these electronic devices are all controlled by the controller of the granulator body 1 itself, and their connection method is a conventional electrical connection. The lifting cylinder 17 and the horizontal pushing cylinder 25 are supplied by an external air source, and no further details will be given here.

[0038] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
