Technical Field

[0001] The utility model relates to the technical field of fertilizer granulation, in particular to a granulation device for fertilizer production. Background Art

[0002] Fertilizer granulation technology will play an increasingly important role in agricultural production; as an advanced fertilizer production equipment, agricultural granulator has the advantages of improving fertilizer utilization, facilitating storage, transportation and application, and improving product quality.

[0003] The existing granulation device for fertilizer production can refer to the Chinese utility model patent with authorization announcement number CN217796010U, which discloses a composite granulation device for microbial fertilizer production, "including a mixing box, the top right side of the mixing box is connected to a feeding hopper, the interior of the mixing box is provided with a stirring mechanism, the bottom of the mixing box is connected to a discharge pipe and the pipe mouth of the discharge pipe is connected to an extrusion barrel, the interior left side of the extrusion barrel is provided with an extrusion molding mechanism, and the interior right side of the extrusion barrel is provided with a clearing mechanism."

[0004] When the above-mentioned device is in use, the existing device utilizes fertilizer to enter the extrusion barrel through the discharge pipe. Due to the extrusion molding operation, the extrusion plate moves to the right, and the fertilizer will fall to the left side of the extrusion plate during the movement. However, during the extrusion molding process, it is often necessary to convert the fertilizer raw materials into granules to facilitate the subsequent loading and use of the fertilizer. In addition, effective measures are required in the process of extruding the raw materials to avoid the extruded raw materials being too long, which affects the next step of granulation. Therefore, a granulation device for fertilizer production that solves the above-mentioned problems is needed. Utility Model Content

[0009] As a preferred technical solution of the present invention, the external teeth are arranged on the outer wall of the diverter disc at a nearly 90° angle, and meshing teeth are provided on the top of the forward and reverse motors.

[0010] As a preferred technical solution of the present invention, the conveying channel is arranged directly above the shaking screen, and the diameter of the conveying channel is smaller than the diameter of the shaking screen.

[0011] As a preferred technical solution of the present invention, the blanking plate is inclined at 30° in the inner cavity of the granulation tank, and a mounting bar is provided at the bottom of the blanking plate.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The granulating device for fertilizer production uses a telescopic extruder, a feeding channel, an extrusion trough, a diverter plate, a cutting circle, and a forward and reverse motor on the device in coordination with each other. When the feeding channel on the device is loaded with fertilizer raw materials, the telescopic extruder is used to extrude the raw materials downward so that the raw materials fall downward through the extrusion trough. The diverter plate is driven to rotate by the power of the forward and reverse motor near the extrusion trough, so that the portion extruded out of the extrusion trough is automatically cut off by the cutting circle, thereby avoiding the problem of the fertilizer raw material prototype being too long during the granulation process. The misalignment of the cutting circle and the extrusion trough is used to temporarily block the falling of the fertilizer raw materials.

[0014] 2. The granulating device for fertilizer production uses the humidification spray, belt heating and rotating motor, shaking screen and sieve holes on the device to cooperate with each other. When the shaking screen on the device receives the fertilizer raw materials in a softened state, it uses the belt heating and humidification spray to heat harden and humidify the surface, and the shaking screen enters a rotating state under the power output of the rotating motor. The circular outer wall and sieve holes of the shaking screen are used to simulate a manual shaking screen, so that the fertilizer raw materials collide into a spherical shape during the rotation process, and the sieve holes are used for screening, thereby enabling the device to complete the granulation of the fertilizer raw materials.
