Description

Technical Field

[0001] The utility model belongs to the technical field of organic fertilizer production, in particular to an extrusion granulation device for organic fertilizer production. Background Art

[0002] Organic fertilizers, primarily derived from plants and animals, are carbon-containing materials applied to the soil to provide plant nutrition. Processed from biomass, animal and plant waste, and plant residues, they are free of toxic and harmful substances and are enriched with beneficial substances, including various organic acids, peptides, and nutrients. They not only provide comprehensive nutrition for crops but also have a long-lasting effect, promoting microbial growth and improving the physical and chemical properties and biological activity of the soil. During production, organic fertilizers are often granulated to better dissolve in the soil and facilitate plant absorption.

[0003] Before organic fertilizer extrusion granulation, it is first necessary to put several pulverized organic fertilizer raw materials into a batch mixer for mixing, spray water mist in time to make the mixed raw material water content reach 35-50%, and then put the mixed raw materials into an extrusion granulator for extrusion granulation. After granulation is completed, the organic fertilizer particles are transported from the granulator to a drying box for drying. However, the organic fertilizer particles produced from the granulator have a high water content, and are easily adhered and lumped after collision between the organic fertilizer particles during transportation. This causes the organic fertilizer particles after drying to have irregular sizes and large weight deviations between the particles, resulting in poor product consistency, which has a negative impact on the quality of the final organic fertilizer product. Therefore, it is necessary to design an organic fertilizer production extrusion granulation device that avoids adhesion and lumping between the organic fertilizer particles after granulation. Utility Model Content

A vibration motor 10 is fixedly connected to the bottom of the vibrating screen 9.

[0019] In order to produce organic fertilizer particles by extruding organic fertilizer raw materials, the extrusion granulation mechanism includes an auger conveyor 11, a granulation disk 12, and a scraper 13. The granulation disk 12 is provided with a plurality of particle outlet holes 14. The side of the granulation disk 12 is fixedly connected to the output end of the auger conveyor 11. The auger conveyor 11 is driven by an auger motor 15. The back side of the scraper 13 is fixedly connected to the driving mechanism, and the blade side of the scraper 13 is in contact with the outer side of the granulation disk 12.

[0020] In order to drive the scraper 13 to rotate around the axis of the rotating rod 20 and cut the organic fertilizer strips squeezed out of the granulation hole 14 of the granulation disk 12 into organic fertilizer particles, the driving mechanism includes a driving motor 16 and an isolation box 17. The driving motor 16 is fixedly connected to the top of the working box 1. The upper end of the isolation box 17 is fixedly connected to the top wall of the working box 1. A first bevel gear 18 and two symmetrically arranged second bevel gears 19 are provided in the isolation box 17. The two second bevel gears 19 are meshed and connected to the first bevel gear 18.

[0022] The specific working process of this utility model is as follows:

[0023] The mixed organic fertilizer raw materials are added to the input ends of the auger conveyors 11 on both sides of the upper end of the device, and the vibration motor 10, the drive motor 16, the hot air generator 4, and the auger motor 15 are started respectively. The auger motor 15 drives the auger conveyor 11 to work, and the auger conveyor 11 continuously transports the added organic fertilizer raw materials toward the output end. Under the obstruction of the granulation disk 12, the organic fertilizer raw materials are squeezed out from the particle holes 14 on the granulation disk 12. The drive motor 16 drives the scraper 13 to rotate through a series of transmissions to cut off the organic fertilizer squeezed out of the particle holes 14, forming organic fertilizer particles that fall into the lower part of the working box 1. The hot air generator 4 continuously blows hot air into the working box 1, and the hot air flow is dispersed into multiple strands under the action of the air dispersion plate 3. The falling organic fertilizer The particles reduce their falling speed under the action of hot air, and the hot air takes away the moisture contained in the particles, completing the preliminary drying. The surface hardness of the organic fertilizer particles after preliminary drying is higher than that of the organic fertilizer particles just after being extruded and pelletized, and the water content is lower, which can avoid mutual adhesion and agglomeration during transportation. The preliminarily dried organic fertilizer particles fall downward onto the vibrating screen 9 in the collecting hopper 6. The vibrating screen 9 continuously screens the organic fertilizer particles falling thereon under the drive of the vibration motor 10. The debris with a particle size smaller than the aperture falls through the vibrating screen 9 and is discharged from the debris discharge port 8. After being collected, it is crushed again and used as raw material to produce organic fertilizer particles. The complete organic fertilizer particles are discharged from the particle discharge port 7 along the inclined vibrating screen 9 and transported to the next section via the conveyor belt.
