Description

Technical Field

[0001] The utility model relates to the technical field of granulators, in particular to a spray granulator. Background Art

[0002] Spray granulator is a kind of equipment commonly used to prepare microparticles or particles. It sprays liquid solution or suspension into small droplets, and then transforms these droplets into solid particles through a drying process. This technology is widely used in the pharmaceutical, food, chemical and other industries to prepare granular drugs, food additives, chemical raw materials, etc.

[0003] In the prior art, the announcement number is: CN218365873U, and the patent name is a Chinese utility model patent of a vibrating spray granulator. A spray granulator is disclosed. The patent records that the particles generated by the tank body fall into the guide part through the lower hopper, and then slide between the drum and the roller. The power component is a motor, which drives the rotating shaft and the roller to rotate, and at the same time drives the drum to rotate in the opposite direction through the transmission component. The material particles are on the friction component between the drum and the roller. The reverse rotation force generated by the two rubs the material. The gap between the two is the same as the size of the standard material particles. After the agglomerated material particles are rubbed, they are decomposed into qualified materials and fall from the gap to achieve the dispersion of the agglomerated materials, which effectively improves the production quality. In this solution, after the particles of different sizes are screened out, it is necessary to manually recycle the unqualified raw material particles, which greatly reduces the work efficiency and increases the problem of manpower. In order to solve the technical problem, the utility model proposes a raw material feeding device for packaging bag production. Utility Model Content

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0018] like Figure 1-3As shown, a spray granulator comprises a mixing box 1, a motor 2 is fixedly connected to the bottom of the mixing box 1, and a rotating shaft 3 is fixedly connected to the output end of the motor 2, and a plurality of stirring rods 4 are fixedly connected to the outer wall of the rotating shaft 3, and the stirring rods 4 and the feeding pipe 5 are both rotatably connected to the inside of the mixing box 1, and a feeding pipe 5 is fixedly connected to the top of the mixing box 1, and a water pump 6 is fixedly connected to the top of the mixing box 1, and a feeding pipe 7 is fixedly connected to the output end of the water pump 6, and the feeding pipe 7 passes through the water pump 6 and extends to the inside of the mixing box 1, and an atomizing nozzle 9 is arranged at the other end of the feeding pipe 7, and a drying chamber 8 is arranged outside the mixing box 1, and the other end of the feeding pipe 7 passes through the drying chamber 8 and extends to the inside of the drying chamber 8, and A screen 10 is arranged inside the drying chamber 8, and a feeding mechanism is arranged between the drying chamber 8 and the mixing box 1, the feeding mechanism comprising a rotating column 14 and a dragon leaf 15, a discharge pipe 11 is fixedly connected to the outer wall of the drying chamber 8, the other end of the discharge pipe 11 is fixedly connected to the outer shell 12, and a motor 2 13 is fixedly connected to the bottom of the outer shell 12, and the rotating column 14 is fixedly connected to the output end of the motor 2 13, and the dragon leaf 15 rotates in contact with the inner wall of the outer shell 12, and the dragon leaf 15 is fixedly connected to the outer wall of the rotating column 14, a discharge pipe 16 is fixedly connected to the outer side of the top of the outer shell 12, a grinder 17 is fixedly connected to the top of the mixing box 1, and the other end of the discharge pipe 16 extends to the inside of the grinder 17.

[0019] The raw materials are poured into the mixing box 1 through the feed pipe 5, and the motor 1 2 at the bottom of the mixing box 1 is started, which drives the rotating shaft 3 and the stirring rod 4 to ensure that the raw materials are fully mixed and stirred. After the stirring is completed, the water pump 6 is started to extract the mixed raw materials and convey them to the inside of the atomizing nozzle 9 through the feeding pipe 7. The atomizing nozzle 9 atomizes the raw materials and sprays them in the drying chamber 8. In the drying chamber 8, the high temperature heating begins to make the atomized raw materials begin to solidify into particles, and these particles fall on the screen 10. The drying chamber 8 will vibrate when working, and the larger particles will be sent into the shell 12 through the discharge pipe 11, while the smaller particles will fall at the bottom of the drying chamber 8. The motor 2 13 is started, which will drive the rotating column 14 and the dragon leaf 15.

After grinding, the generated powder will return to the mixing box 1 for reprocessing. Through the cooperation of these steps, the working efficiency of the whole process has been significantly improved.

[0020] It should be noted that in actual use of the device, first, the raw material feed pipe 5 is poured into the interior of the mixing box 1, and then the motor 2 at the bottom of the mixing box 1 is started. Under the action of the motor 2, the rotating shaft 3 is driven to rotate, and the stirring rod 4 is driven to stir. After the stirring is completed, the water pump 6 is started, and the mixed raw materials in the mixing box 1 are extracted under the flow of the water pump 6 and transported to the interior of the atomizing nozzle 9 through the feeding pipe 7. Under the action of the atomizing nozzle 9, the raw materials will be atomized and sprayed into the interior of the drying chamber 8. Granulation begins through high-temperature heating inside the drying chamber 8, and the granules produced will fall. On the screen 10, of course, vibration will be generated when the drying chamber 8 is working, and larger particles will flow into the interior of the outer shell 12 through the discharge pipe 11, and smaller particles will fall to the bottom of the drying chamber 8, and then by starting the second motor 13, the rotating column 14 and the dragon leaf 15 will be driven to rotate under the action of the second motor 13. The rotation of the dragon leaf 15 will enlarge the particles through the discharge pipe 16 to the grinder 17, and then by starting the grinder 17, the larger particles will begin to be ground, and the powder will return to the mixing box 1 for reprocessing. Through the cooperation between them, the work efficiency is greatly improved.
