Technical Field

[0002] As an important pharmaceutical and chemical equipment, boiling granulator plays a key role in the field of particle preparation. Its core technology is to make the material form a boiling state through high-speed hot air flow, and at the same time combine it with a granulating device to achieve 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, a Chinese invention with authorization announcement number: CN 215743285 U discloses a boiling 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.

The top wall of the telescopic groove and the top of the fixed block 110 are jointly connected to a number of telescopic springs 124 arranged equidistantly in an array, and the active rotating rod and the reciprocating screw 108 are jointly sleeved with a second synchronous belt 104 through a synchronous wheel.

[0020] like Figure 1 to Figure 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.

[0021] like Figure 1 to Figure 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.

[0022] 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; 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; The sliding drive device is specifically an electric slide rail, which is connected to the control panel 10. When the size of the screen hole needs to be adjusted, 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 adjustment screens to slide relative to the other adjustment screen. During the sliding process, the screen holes of the two adjustment screens are gradually staggered, thereby changing the size of the screen hole. It should be noted that the size of the screen hole is determined by the aperture of the two adjustment screens themselves and the degree of staggering of the screen holes. By adjusting the sliding position of the adjustment screen, the size of the screen hole can be adjusted; It should be noted that the size of the sieve holes 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 accurately adjusts the left and right position between the two layers of the adjustment screen. The left and right position needs to be adjusted by the operator according to the specific raw materials to be produced. Furthermore, during granulation, the control panel 10 starts the active motor 105 connected to its control, and the active motor 105 drives the follower rotating rod 123 and the reciprocating screw 108 to rotate 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 pushes the convex plate 113 downward reciprocatingly. When the convex plate 113 is pushed, the screening component 101 is driven to vibrate up and down, effectively avoiding the phenomenon that the raw materials are blocked when passing through the sieve holes during boiling. When the pressing block 114 is separated from the convex plate 113, the screening component 101 is quickly reset under the action of the shaking spring 102, ensuring continuous and efficient vibration of the screening component 101. 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. 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. 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.

[0023] Embodiment 2: Figure 1 to Figure 9As shown, on the basis of Example 1, this embodiment further proposes a boiling granulator with uniform granulation, which also has the following structure: a multi-stage spraying mechanism 2 is arranged inside the sealed bin 11, and the multi-stage spraying mechanism 2 includes two symmetrically arranged upper granulation nozzles 201 and two symmetrically arranged lower granulation nozzles 214, and a guide pipe 204 is commonly connected between the two upper granulation nozzles 201 and the two lower granulation nozzles 214, and a conveying pipe 206 is commonly connected between the two guide pipes 204, and 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.

[0024] Both sides of the two upper granulation nozzles 201 and the two lower granulation nozzles 214 are fixedly connected with movable plates 211, one side of the two movable plates 211 is rotatably mounted with support plates 210, the two support plates 210 are fixedly arranged inside the sealing chamber 11, one side of the two movable plates 211 is commonly fixedly connected with a swing rod 213, the outer circumference of the four swing rods 213 is slidably sleeved with a movable sleeve 212, the outer circumference of the movable sleeve 212 is fixedly connected with a telescopic rod 215, the outer circumference of the telescopic rod 215 is slidably sleeved with a rotating block 207, and one side of the rotating block 207 corresponding to the two upper granulation nozzles 201 is fixedly connected A second rotating shaft 209 is connected, and one side of the rotating block 207 corresponding to the two lower granulating nozzles 214 is fixedly connected with a first rotating shaft 208. The two first rotating shafts 208 and the two second rotating shafts 209 are rotatably installed inside the sealing bin 11. A fourth synchronous belt 203 is jointly sleeved between the first rotating shaft 208 and the second rotating shaft 209 through a synchronous wheel. An auxiliary motor 202 is installed on one side of the granulating bin 4. The output end of the auxiliary motor 202 is coaxially fixedly connected to one of the first rotating shafts 208 through a coupling. The other first rotating shaft 208 and the active rotating rod are jointly sleeved with a fifth synchronous belt 216 through a synchronous wheel.

[0025] 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 the compressed air and the adhesive solution according to a preset ratio. 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 the two guide pipes. Subsequently, the mixed liquid is evenly sprayed on the fluidized powder on the fluidized bed in the form of atomization. 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 is synchronously rotated between the active rotating rod and the fifth rotating shaft. The first rotating shaft 208 and the second rotating shaft 209 rotate synchronously under the action of the fourth synchronous belt 203, and the rotating block 207 is driven to rotate together when the first rotating shaft 208 and the second rotating shaft 209 rotate, and the rotation of the rotating block 207 drives the telescopic rod 215 slidably connected thereto to rotate, and the rotation of the telescopic rod 215 causes the movable sleeve 212 and the swinging rod 213 movably arranged inside the movable sleeve 212 to swing up and down, and the movable plates 211 at both ends of the swinging rod 213 are connected to the upper granulation nozzle 201 and the lower granulation nozzle 214, so they also swing up and down accordingly, and in the process of swinging, the atomized mixed liquid is evenly sprayed onto the surface of the empty raw material; By arranging a group of upper granulation nozzles 201 and a group of lower granulation nozzles 214 at different heights of the granulator, the adhesive can be accurately sprayed on different floating levels of the raw material, ensuring that different parts and layers of the raw material can be evenly wetted, thereby improving the uniformity and quality of granulation. It should be noted that the two first rotating shafts 208 are driven by the auxiliary motor 202 and the fifth synchronous belt 216 sleeved on the active rotating rod respectively, the output power of the auxiliary motor 202 is substantially the same as that of the active motor 105, and a certain deviation in the rotation speed of the two first rotating shafts 208 does not affect the spraying efficiency.

[0026] like Figure 1 to Figure 9 As shown, the control panel 10 is control-connected to the active motor 105 , the auxiliary motor 202 , the peristaltic pump 205 , the screening assembly 101 and the crushing motor 120 .

[0027] 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.

[0028] 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.
