Description

Fluidized bed coating machine raw materials container structure Technical Field The utility model relates to the technical field of raw materials of coating machines, in particular to a raw material container structure of a fluidized bed coating machine. Background In the pharmaceutical field, the uniformity of the coating film thickness of the fluidized bed coating machine is a key element, because the uniformity of the coating film thickness is closely related to the release performance of the medicine in a human body, the more and more uniform the material circulation times tend to be in the coating operation, the more uniform the formed coating film is, when the fluidized plate is positioned, and a region with slow fluidization speed exists between a material pot and a guide cylinder, the phenomenon is particularly prominent in large-scale production equipment, particularly in the regions between a plurality of guide cylinders and cylinder walls, if the range of the fluidization slow regions can be reduced, the material can be promoted to enter the guide cylinders more rapidly and directly, the uniformity of the coating can be obviously improved, thereby laying a solid foundation for the stable release and the drug effect exertion of the medicine, powerfully protecting the quality and the curative effect of the medicine, and being helpful for improving the overall efficiency and the benefit of the pharmaceutical production flow. The fluidized bed coating machine material container structure contains container body, feed inlet, discharge outlet, atomizing system, air distribution plate, gas vent and control system, and its theory of operation is that put the raw materials in the container, evenly blow air through air distribution plate and form the fluidized bed, atomizing system spouts on the raw materials after atomizing coating liquid, and raw materials granule forms the coating layer with atomizing liquid contact, and the coating product is discharged from the discharge outlet, and exhaust gas moisture is discharged by the gas vent, and in-process control system monitors control relevant parameter. In the prior art, partial coating is uneven to directly cause the difficult accurate control of medicine release speed in medicine production, partial coating is too thick to delay medicine release in the region, so that medicine is difficult to play a role in preset time and parts, the treatment effect is affected, the product is difficult to reach the quality standard due to uneven coating, reworking or scrapping treatment is required, abnormal adhesion, caking and the like of materials occur in the fluidization process due to uneven coating, and the fluidized bed coating machine raw material container structure is provided for solving the problems. Disclosure of utility model In order to make up for the defects, the utility model provides a raw material container structure of a fluidized bed coating machine, which aims to solve the problems that in the prior art, coating is uneven, so that the release speed of a medicine is difficult to control accurately, the treatment effect is affected, a product cannot meet the quality standard and needs to be reworked or scrapped, and abnormal phenomena such as adhesion and caking of materials in the fluidization process are caused. In order to achieve the above purpose, the present utility model adopts the following technical scheme: The fluidized bed coating machine raw material container structure comprises a plurality of guide cylinders, wherein the bottoms of the guide cylinders are fixedly connected with a material pot, the inside of the material pot is fixedly connected with a plurality of guide blocks, and fluidization components for guiding are arranged in the guide cylinders; As a further description of the above technical solution: the fluidization component comprises a plurality of fluidization plates, the tops of the fluidization plates are fixedly connected to the bottoms of the guide cylinders, and the outer walls of the fluidization plates are fixedly connected to the inner wall of the material pot; As a further description of the above technical solution: The far sides of the guide barrels are fixedly connected to the near sides of the guide blocks, and the tops of the fluidization plates are fixedly connected to the bottoms of the guide barrels. The utility model has the following beneficial effects: According to the utility model, air is driven by a fan to the bottom of a material pot through a pipeline, the bottom of a fluidization plate is connected through mat type net bolts, and air guiding holes around the fluidization plate uniformly disperse the air, so that materials are well fluidized in all areas of the material pot, after fluidization, a flow guiding block regulates and controls the flow direction according to the characteristics of the materials, high-efficiency flow distribution is realized according to the distribution height of the
