Description

Technical Field

[0001] This utility model relates to drying technology, specifically a dryer for preventing caking. Background Technology

[0002] A dryer is a mechanical device that uses heat energy to reduce the moisture content of materials, used for drying objects. The dryer heats the material to vaporize and release the moisture (generally water or other volatile liquid components) to obtain a solid material with a specified moisture content. Wet material is quantitatively added into the tower by a feeder and undergoes thorough heat exchange with hot air. Larger, wetter materials are mechanically broken down by an agitator, while materials with lower moisture content and smaller particle size rise with the rotating airflow and are conveyed to a separator for gas-solid separation. The finished product is collected and packaged, while the exhaust gas is treated by a dust removal device before being discharged into the atmosphere.

[0003] However, existing dryers are not easy to stir, crush and separate large materials during drying, which causes the moisture inside the material to be unable to be discharged, resulting in the material clumping. The clumped material occupies the internal space of the dryer and blocks the pipes, affecting the normal operation of the equipment. Moreover, the clumped material is easy to mix into the product, causing the product moisture content to exceed the standard and affecting the product quality. Utility Model Content

[0004] To address the shortcomings of the prior art, this utility model provides an anti-caking dryer that can pre-crush large-volume materials and, in conjunction with an agitator, perform secondary crushing to reduce the particle size of the materials. It also ensures that hot air is evenly sprayed onto the surface of the materials, resulting in uniform heating and preventing material agglomeration.

[0006] Preferably, the drive unit includes a motor, a synchronous belt, and three synchronous pulleys. The motor is fixed to the top of the drying chamber, and the three synchronous pulleys are respectively fitted onto the top of the motor output shaft, the top of the stirring shaft, and the top of the pulverizing shaft. The synchronous belt passes around the three synchronous pulleys in sequence and is connected end to end.

[0007] Preferably, the crushing unit includes two blade sets, both of which are fixed to the crushing shaft and are located at the top and bottom of the crushing chamber, respectively.
