Description

Technical Field

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

[0002] A granulating dryer is a device widely used in industries such as pharmaceuticals, food, and chemicals. Its main function is to process materials through specific processes to form them into granular shapes and achieve the purpose of drying. The working principle of a granulating dryer mainly involves processes such as fluidization, dust removal, atomization, and solidification of materials. Air is heated by a heater and enters the bottom of the fluidized bed, coming into contact with the materials and making them fluidized. At the same time, the mother liquor or binder is sent to the atomizing nozzle through a pressure generating device such as a pressure pump. After atomization, it is coated on the surface of the fluidized particles or makes the particles bond to each other. Through continuous fluidization, coating, and drying, the particles gradually grow and are discharged from the discharge port of the fluidized bed after reaching the required particle size. During the atomization process, the size of the liquid 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 manner. The hot air enters the tower through the hot air distributor on the top cover, forming a downward streamline air flow. The mist droplets are sprayed upward into the hot air flow, form spherical shapes due to surface tension, and quickly evaporate and dry, finally forming dry spherical particle powders.

[0003] However, when the existing granulating dryers are actually used, they still have the following deficiencies;

[0004] First of all, when the existing granulating dryers are in use, a collection box is used to collect the finally formed spherical particles. At this time, some mist particles still adhere to the surface of the spherical particles. When they accumulate at the bottom of the collection box, the mist particles 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 thicken, thus affecting the size of its collection volume.

[0005] Secondly, when the existing granulating dryers clean their components, the impurity particles brushed out will fall, and the existing granulating dryers do not have the function of absorbing and treating the fallen impurity particles.

[0006] Therefore, in order to solve the above problems, a granulating dryer with an automatic cleaning function is needed. Summary of the Invention

[0007] In order to overcome the above-mentioned defects of the prior art, the present invention provides a granulating dryer with an automatic cleaning function to solve the problems existing in the above background art.

The formed material particles fall downward from the discharge bin 119 into the collection box 201 for collection. When it is necessary to clean the bottom surface of the collection box 201, after taking out the material particles collected in the collection box 201, the flipping motor 205 drives the rotating shaft 203 to drive the box bottom plate 204 to rotate 180 degrees, so that the bottom surface of the box bottom plate 204 adhering to the atomized particles faces downward. Then, the electric cylinder 216 drives the push rod 215 to push the end block 208 upward, so that the brush roller 213 contacts the bottom surface of the box bottom plate 204. Driven by the cleaning motor 214, the brush roller 213 rotates to clean the bottom surface of the box bottom plate 204. The transverse movement motor 211 drives the lead screw 210 to rotate, so that the brush roller 213 moves transversely to completely clean the bottom surface of the box bottom plate 204, and its cleaning function is realized in this way. When the brush roller 213 is cleaning, the generated dust will fall above the cover plate 305. The fan 304 exhausts outward, and the dust is sucked into the dust collection box 302 through the through groove 306 and intercepted and filtered by the filter plate 303.
