[0002] In the fertilizer processing process, in order to avoid the caking phenomenon during the storage of fertilizer particles, the anti-caking powder feeding stirring device is needed to fully mix the fertilizer particles and the anti-caking powder, the anti-caking powder is in the form of ultra-fine powder, which can block the capillary holes on the surface of the fertilizer, prevent the migration of moisture inside the fertilizer particles to the surface, and the ultra-fine powder is strongly adsorbed on the surface of the fertilizer particles, effectively preventing the contact between the fertilizer particles.
[0003] In the prior art, the anti-caking powder feeding stirring device is mainly composed of a rotating drum fluidized bed, which simultaneously transports airflow, anti-caking powder and fertilizer particles into the rotating drum, and mixes the anti-caking powder and fertilizer particles by airflow. The airflow is mainly transported from the bottom of the rotating drum. During the upward transportation of the airflow, the anti-caking powder and fertilizer particles are blown upward. Since the airflow is vertically from bottom to top, the transportation positions of the fertilizer particles and the anti-caking powder are opposite. The directional airflow cannot ensure that the fertilizer particles and the anti-caking powder are fully mixed. There is a fertilizer mixing blind area, which reduces the mixing uniformity of the airflow for the fertilizer and the anti-caking powder, and reduces the processing quality of the fertilizer particles, thereby prolonging the residence time of the airflow in the rotating drum, and reducing the mixing and stirring efficiency of the fertilizer particles and the anti-caking powder.
[0004] Therefore, the utility model provides an anti-caking powder feeding stirring device to solve the above problems. UTILITY MODEL CONTENTS

[0024] Please refer to Figures 2-5The feeding pipe group 7 includes a plurality of powder feeding pipes 71 and a plurality of fertilizer feeding pipes 72. The plurality of powder feeding pipes 71 are uniformly connected to the outer surface of the rotating drum 4 in a circumferential distribution. The plurality of fertilizer feeding pipes 72 are uniformly connected to the outer surface of the rotating drum 4 in a circumferential distribution and are located directly above each powder feeding pipe 71. The top ends of the plurality of powder feeding pipes 71 are connected to each other by a first annular pipe 73. The top ends of the plurality of fertilizer feeding pipes 72 are commonly connected to each other by a second annular pipe 74. The powder feeding pipes 71 and the fertilizer feeding pipes 72 are both bent. The first annular pipe 73 and the second annular pipe 74 are both sleeved with the rotating drum 4. The first annular pipe 73 is sleeved with the second annular pipe 74. The two sides of the top of the first annular pipe 73 are both connected to a first conveying pipe 75.

[0025] Specific embodiments: Start the external fan, quickly convey the gas into the interior of the rotating drum 4 through the two air inlet pipes 5. The gas outlets of the two air inlet pipes 5 are opposite. The gas flows input into the interior of the rotating drum 4 through the two air inlet pipes 5 collide with each other, forming a uniform mixed flow.
