Description

Technical Field

[0001] The present application relates to the technical field of fluidized bed granulation coating machines, and in particular to a fluidized bed granulation coating machine with a highly automated structure. Background Art

[0002] Fluidized bed coating machine is an improved drying device in the pharmaceutical industry. Fluidized beds include back-mixing flow, piston flow, vibration, contact, multi-layer fluidized bed and other types. The fluidized bed uses an atomization operating system and coating method to complete the granulation, pellet making, coating and drying processes in the fluidized bed at one time, reducing energy consumption.

[0003] After searching, the existing patent (application number CN201921983773.0) discloses a cyclone fluidized bed coating machine, including a frame and a fluidized bed body fixed to the frame, the fluidized bed body including a top cylinder, a drying chamber, a silo and a bottom cylinder connected in sequence from top to bottom, the silo is provided with a moving component, the silo is detachably connected between the drying chamber and the bottom cylinder, a mesh plate is provided at the bottom of the silo, a plurality of air outlet holes are evenly opened on the mesh plate, and the cross section of each of the air outlet holes is set to be semicircular. Since the air outlet holes are set to be semicircular, the hot air will continue to spirally rise in the silo and the drying chamber, so the material will be in the drying chamber and the silo in a spiral manner with the hot air. Since the material is light, it is not easy to separate from the cyclone and collide with the side wall of the silo, so it can protect the material, thereby improving the quality of the coating. In the process of realizing the utility model, the inventor found that the prior art has the following problems: The existing cyclone fluidized bed coating machine does not have an automatic material unloading structure. After the coating work is completed, the bottom drum needs to be manually removed to take out the materials. This material taking method is not only time-consuming and labor-intensive, but also requires stopping the machine to take out the materials, and cannot ensure the continuous production of the coating work. In addition, when the existing cyclone fluidized bed coating machine is performing processing work, the coating agent will fall on the cyclone plate used for air supply, and it is not easy to clean the bottom drum, and manual cleaning is time-consuming and labor-intensive, inconvenient for cleaning and maintenance, and may affect subsequent processing work.
