Description

Technical Field

[0001] The invention relates to the technical field of auxiliary equipment for a granulating dryer, and more particularly to a granulating dryer with an automatic cleaning function. Background Art

[0002] Granulation dryer is a kind of equipment widely used in pharmaceutical, food, chemical and other industries. Its main function is to process materials through specific processes to form granules and achieve the purpose of drying. The working principle of granulation dryer mainly involves the fluidization, dust removal, atomization, solidification and other processing processes of materials. After being heated by the heater, the air enters the bottom of the fluidized bed, contacts with the material and makes it fluidized. At the same time, the mother liquid or binder is sent to the atomization nozzle through the pressure pump and other pressure-generating equipment. After atomization, it is coated on the surface of the fluidized particles or the particles are bonded to each other. After continuous fluidization, coating and drying, the particles gradually grow and are discharged from the fluidized bed outlet after reaching the required particle size. In the atomization process, the size of the droplets is inversely proportional to the pressure, and the production capacity of the nozzle is proportional to the square of the pressure. The mist particles and hot air work in a mixed flow mode. The hot air enters the tower through the hot air distributor on the top cover to form a downward streamline air flow. The mist droplets are sprayed into the hot air flow from bottom to top. Due to the surface tension, they form a sphere and evaporate and dry quickly, finally forming a dry spherical granular powder. However, the granulation dryer under the existing technology still has the following shortcomings in actual use; First, when the granulation dryer under the prior art is in use, a collection box is used to collect the final granular spheres. At this time, some mist particles are still adhered to the surface of the spherical particles. When the mist particles accumulate at the bottom of the collection box, they will adhere to the bottom of the collection box, thereby polluting the collection box. Over time, the bottom surface of the collection box will also become thicker, thereby affecting its collection volume. Secondly, when the granulation dryer under the prior art cleans the parts, the impurity particles brushed out will fall, but the granulation dryer under the prior art does not have the function of absorbing and treating the fallen impurity particles; Therefore, in order to solve the above problems, it is necessary to provide a granulation dryer with an automatic cleaning function. Summary of the invention
