Description

Technical Field

[0001] The present invention relates to the technical field of fluidized granulators, and specifically, to a fluidized granulator with uniform granulation. Background Art

[0002] As an important pharmaceutical and chemical equipment, the fluidized granulator plays a key role in the field of particle preparation. Its core technology is to make the material form a fluidized state through high-speed hot air flow, and at the same time, combined with the granulation device, to achieve the uniform formation of particles. This equipment can efficiently convert raw materials into the required granular products and is widely used in many industries such as medicine, food, and chemical industry.

[0003] In the prior art, the Chinese invention with the authorization announcement number: CN 215743285 U discloses a fluidized granulator with uniform granulation. In this patent, although the granulator can ensure the uniformity and efficiency of granulation to a certain extent, there are still some potential problems. First, the granulator that highly depends on the air flow system has a high risk of pipeline or filter screen blockage during operation, but no effective filter screen cleaning device is provided, which may affect the continuous and stable operation of the equipment. Second, for raw materials with larger particle sizes, no linkage processing device is provided, which may cause some raw materials to be unable to be effectively processed and affect the granulation effect. Finally, it only sets one spray head, but in the actual granulation process, the distribution of raw materials at the bottom and those floating higher is different, and it may be difficult to achieve the best granulation effect simply relying on one spray head.

Subsequently, the driving motor drives the pressing block and the convex plate to reciprocate intermittently, which not only pushes the screening assembly to vibrate to avoid blockage, but also ensures the continuous and efficient operation of the screening assembly. Further, the reciprocating lead screw drives the push rod and the push plate to reciprocate left and right, pushing the unqualified raw materials into the crushing tank for crushing and processing, forming a closed-loop processing flow. In the granulation stage, the atomized mixed liquid is evenly sprayed on the raw materials on the fluidized bed through the upper and lower granulation nozzles. The linkage effect of the rotating block and the swing rod ensures uniform spraying. As the raw materials roll and collide in the granulator, the particles gradually increase and become dense, and finally fall into the bin through the adjusted screen aperture, achieving the effect of uniform granulation of the fluidized bed granulator and improving the granulation quality and efficiency.

[0033] As Figures 1 to 9 shown, a backing plate 112 is fixedly arranged on one side of the granulation bin 4. A driving motor 105 is installed on one side of the backing plate 112. The output end of the driving motor 105 is fixedly connected to a coaxial driving rotating rod through a coupling. The driving rotating rod is rotatably installed inside the granulation bin 4 and the sealing bin 11 at the same time. A follower rotating rod 123 is rotatably installed inside the sealing bin 11. A first synchronous belt 103 is sleeved on the driving rotating rod and the follower rotating rod 123 through synchronous wheels. A pressing block 114 is fixedly sleeved on the outer peripheral surface of the follower rotating rod 123. A convex plate 113 is fixedly connected to one side of the screening assembly 101. The pressing block 114 is located directly above the convex plate 113. Two symmetrically arranged sliding grooves 111 are formed at the bottom of the screening assembly 101. A push rod 106 is slidably assembled inside the two sliding grooves 111 at the same time. A connecting block 109 is fixedly connected to the bottom of the push rod 106. A reciprocating lead screw 108 is rotatably installed inside the sealing bin 11. A movable block 107 is sleeved on the reciprocating lead screw 108 through a thread. A fixed block 110 is fixedly arranged at the top of the movable block 107. An expansion slot is formed inside the connecting block 109. The top of the fixed block 110 is slidably connected inside the expansion slot. A plurality of expansion springs 124 arranged at equal intervals in an array are connected between the top wall of the expansion slot and the top of the fixed block 110. A second synchronous belt 104 is sleeved on the driving rotating rod and the reciprocating lead screw 108 through synchronous wheels.

[0034] AsFigures 1 to 9 As shown, arc filter plates 126 are rotatably installed on both sides of the push rod 106, sliding rods 125 are fixedly installed on both sides of the two arc filter plates 126, and pouring grooves 127 are opened inside the two movable grooves 115. The sliding rods 125 are slidably connected inside the pouring grooves 127.

[0035] like Figures 1 to 9 As shown, the two crushing outer covers 116 are provided with a feed port and a discharge port, the feed port is connected to a feed hopper 117, the feed hopper 117 is fixedly nested in the sealed bin 11, the two crushing outer covers 116 are provided with a crushing motor 120, the two crushing outer covers 116 are provided with two symmetrically arranged crushing rods 122, the outer circumferential surfaces of the crushing rods 122 are fixedly sleeved with crushing sticks 119, the crushing outer covers 116 are provided with a crushing groove 118, the two crushing sticks 119 are located in the crushing groove 118, the output end of the crushing motor 120 is coaxially connected to one of the crushing rods 122 through a coupling, the two crushing rods 122 are jointly sleeved with a third synchronous belt 121 through a synchronous wheel, and the discharge port is connected to the bin 7.

[0036] In this embodiment, when the granulation operation is performed, first, the detachable silo 7 is removed from between the granulation silo 4 and the base 6, then the granulation raw materials are poured into the silo 7, the silo 7 is pushed back to its original position and the silo 7 is sealed with the granulation silo 4 and the base 6 through the control panel 10 to ensure the airtightness of the granulation process, then the induced draft fan installed inside the base 6 is started, and the airflow generated by the induced draft fan blows the material in the silo 7 to make it reach an empty state of agitation and boiling. In this process, the raw materials will first pass through the screening component 101, so that the raw materials are effectively screened before entering the granulation stage, ensuring that the materials entering the granulation silo 4 are uniform and meet the requirements;

[0037] Specifically, the screening component 101 may be structured as follows, comprising two layers of adjustable screens arranged in parallel up and down, and a sliding drive device connected to one of the adjustable screens and adapted to drive the adjustable screen to move left and right, wherein the two adjustable screens slide and fit each other, and by sliding one of the adjustable screens, the screen holes thereof are staggered with the screen holes of the other adjustable screen, thereby realizing the change of the screen hole size, and thus being able to flexibly adapt to the screening requirements of particles of different sizes;

[0038] The sliding drive device is specifically an electric slide rail, which is connected to the control panel 10. When it is necessary to adjust the size of the through-hole, the operator sends an electrical signal to the sliding drive device through the control panel 10. After receiving the signal, the sliding drive device starts to work and pushes one of the adjustable sieves to slide relative to the other adjustable sieve. During the sliding process, the through-holes of the two adjustable sieves are gradually staggered, thereby changing the size of the through-hole. It should be noted that the size of the through-hole is jointly determined by the aperture of the two adjustable sieves themselves and the degree of staggering of the through-holes. By adjusting the sliding position of the adjustable sieve, the adjustment of the size of the through-hole can be achieved;

[0039] It should be noted that the size of the through-hole of the screening component 101 can be flexibly adjusted according to different raw materials and granulation requirements. The screening component 101 is controlled and connected to the control panel 10. The control panel 10 sends an electrical signal to the sliding drive device inside the screening component 101. After receiving the signal, the sliding drive device precisely adjusts the left and right positions between the two layers of adjustable sieves, and the left and right positions need to be adjusted by the operator according to the specific raw materials to be produced;

[0040] Furthermore, during granulation, the control panel 10 starts the driving motor 105 which is controlled and connected to it. The driving motor 105 drives the follower rotating rod 123 and the reciprocating lead screw 108 to rotate simultaneously through the first synchronous belt 103 and the second synchronous belt 104. When the follower rotating rod 123 rotates, it drives the pressing block 114 to rotate. The pressing block 114 repeatedly pushes down the convex plate 113. When the convex plate 113 is pushed, it drives the screening component 101 to produce an up-and-down vibration effect, effectively avoiding the phenomenon that the raw materials block the through-holes during the boiling process. When the pressing block 114 separates from the convex plate 113, the screening component 101 quickly resets under the action of the jitter spring 102, ensuring the continuous and efficient vibration of the screening component 101;

[0041] In addition, as the reciprocating screw 108 rotates, the movable block 107 threadedly sleeved on the screw moves back and forth left and right according to the thread direction of the reciprocating screw 108. Because the connecting block 109 at the bottom of the push rod 106 is internally slidably provided with a fixed block 110, and the bottom of the fixed block 110 is fixedly connected to the movable block 107, the push rod 106 can move up and down with the screening component 101, and can also move back and forth left and right with the movable block 107. The top of the push rod 106 and the bottom of the screening component 101 are in contact with each other, and an appropriate gap is maintained, which avoids direct contact. The damage of the adjusting screen caused by friction is prevented, and the unqualified raw materials blocked by the screening component 101 can be efficiently pushed into the openings of the hoppers 117 on both sides. These raw materials then enter the crushing trough 118 through the hoppers 117. Driven by the crushing motor 120, the two crushing rollers 119 in the crushing trough 118 start to rotate to crush the raw materials with unqualified particle sizes. After the processing is completed, the raw materials fall back into the silo 7 through the opening of the crushing trough 118, and are then blown upward by the airflow generated by the induced draft fan, forming a closed-loop raw material processing process.

[0042] It should be noted that arc filter plates 126 are movably provided on both sides of the push rod 106 and are located on one side parallel to the opening of the feed hopper 117. The main function of the arc filter plates 126 is to capture and screen the large particles of raw materials that fail to pass through the screening component 101. When the push rod 106 is in the process of reciprocating movement, these large particles of raw materials will be effectively dropped and collected inside the arc filter plates 126. When the push rod 106 and its components move to one side of the feed hopper 117, the sliding rod 125 will slide into the notch of the pouring trough 127, triggering the flipping action of the arc filter plates 126. This flipping action ensures that the large particles of raw materials in the arc filter plates 126 can be smoothly introduced into the crushing trough 118 for subsequent crushing processing.

[0043] Furthermore, during the granulation process, the control panel 10 starts the crushing motor 14, and the crushing motor 14 drives the rotating column 3 and the vibration bar 12 fixedly arranged on the rotating column 3. The vibration bar 12 will also generate high-frequency vibrations during the high-speed rotation of the rotating column 3. In this process, the agglomerated materials in the granulation process can be broken up and the fluidization effect can be improved. The vibration bar 12 is made of a polymer composite material, which has excellent mechanical properties and wear resistance, and can achieve the effect of generating high-frequency vibrations during high-speed rotation.

[0044] Embodiment 2: Figures 1 to 9As shown in the figure, on the basis of Embodiment 1, this embodiment also proposes a fluidized granulator with uniform granulation, which further has the following structure: A multi-stage spraying mechanism 2 is arranged inside the sealed bin 11. The multi-stage spraying mechanism 2 includes two symmetrically arranged upper granulation nozzles 201 and two symmetrically arranged lower granulation nozzles 214. A diversion pipe 204 is commonly connected between the two upper granulation nozzles 201 and the two lower granulation nozzles 214. A conveying pipe 206 is commonly connected between the two diversion pipes 204. A peristaltic pump 205 is installed on the granulation bin 4, and one end of the conveying pipe 206 is connected to the peristaltic pump 205.

[0045] On both sides of the two upper granulation nozzles 201 and the two lower granulation nozzles 214, movable plates 211 are fixedly connected. On one side of the two movable plates 211, support plates 210 are rotatably installed. The two support plates 210 are fixedly arranged inside the sealed bin 11. A swing rod 213 is commonly fixedly connected to one side of the two movable plates 211. Movable sleeves 212 are slidably sleeved on the outer circumferential surfaces of the four swing rods 213. A telescopic rod 215 is fixedly connected to the outer circumferential surface of the movable sleeve 212. A rotating block 207 is slidably sleeved on the outer circumferential surface of the telescopic rod 215. On one side of the rotating block 207 corresponding to the two upper granulation nozzles 201, a second rotating shaft 209 is fixedly connected. On one side of the rotating block 207 corresponding to the two lower granulation nozzles 214, a first rotating shaft 208 is fixedly connected. The two first rotating shafts 208 and the two second rotating shafts 209 are rotatably installed inside the sealed bin 11. A fourth synchronous belt 203 is commonly sleeved between the first rotating shaft 208 and the second rotating shaft 209 through a synchronous pulley. An auxiliary motor 202 is installed on one side of the granulation bin 4. The output end of the auxiliary motor 202 is coaxially and fixedly connected to one of the first rotating shafts 208 through a coupling. A fifth synchronous belt 216 is commonly sleeved between the other first rotating shaft 208 and the driving rotating rod through a synchronous pulley.

[0046] In this embodiment, after the raw materials pass through the screening component 101, they are evenly distributed on the fluidized bed. At this time, the control panel 10 starts the peristaltic pump 205 to mix compressed air and the adhesive solution in a preset ratio. After being processed by atomization technology, the atomized mixed liquid is transported to the two upper granulation nozzles 201 and the two lower granulation nozzles 214 through the delivery pipe 206 and two diversion pipes. Subsequently, this mixed liquid is evenly sprayed in the form of atomization on the powder in a fluidized state on the fluidized bed. At the same time, the auxiliary motor 202 is started to drive one of the first rotating shafts 208 to rotate, and the other first rotating shaft 208 rotates synchronously under the action of the driving rotating rod and the fifth synchronous belt 216. The two second rotating shafts 209 then rotate accordingly under the drive of the fourth synchronous belt 203. When the first rotating shaft 208 and the second rotating shaft 209 rotate, they drive the rotating block 207 to rotate together, and the rotation of the rotating block 207 drives the telescopic rod 215 slidably connected to it to rotate. The rotation of the telescopic rod 215 causes the movable sleeve 212 and the swing rod 213 movably arranged inside the movable sleeve 212 to swing up and down. The movable plates 211 at both ends of the swing rod 213 are connected to the upper granulation nozzle 201 and the lower granulation nozzle 214, so they also swing up and down accordingly. During the swinging process, the atomized mixed liquid is evenly sprayed onto the surface of the raw materials placed in the air;

[0047] By arranging a set of upper granulation nozzles 201 and a set of lower granulation nozzles 214 at different heights of the granulator, the adhesive can be accurately sprayed on different floating levels of the raw materials, ensuring that different parts and layers of the raw materials can be evenly wetted, thereby improving the uniformity and quality of granulation. It should be noted that the two first rotating shafts 208 are respectively driven by the auxiliary motor 202 and the fifth synchronous belt 216 sleeved on the driving rotating rod. The output power of the auxiliary motor 202 is roughly the same as that of the driving motor 105. A certain deviation in the rotation speed of the two first rotating shafts 208 does not affect the spraying efficiency.

[0048] As Figures 1 to 9 shown, the control panel 10 is controllably connected to the driving motor 105, the auxiliary motor 202, the peristaltic pump 205, the screening component 101, and the crushing motor 120.

[0049] In this embodiment, as the raw materials are continuously subjected to the action of hot air and adhesive in the granulator, their surfaces gradually become wet and bond together to form particles. These particles roll and collide inside the granulator and continuously merge, so that the particle size gradually increases. When the granulation process is nearing the end, the control panel 10 adjusts the size of the sieve holes of the screening component 101 to increase it to the size of the qualified particle size. At this time, the induced draft fan is still blowing, and the particles will gradually increase and become denser during the granulation process, which will increase their weight and density. As the particles increase, the gravity they are subjected to will also increase accordingly. When the particles meet the weight and size required for granulation, the particles will tend to fall instead of continuing to float, and then fall into the silo 7 through the aperture adjusted by the screening component 101, while those particles with larger particle sizes during the granulation process will be retained on the screening component 101, thereby achieving precise control of the particle size of the finished product. After the granulation is completed, the cleaning bin door 8 is opened. By opening the cleaning bin door 8, the operator can directly clean the sealed bin 11 to prepare for the next granulation.

[0050] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
