Description

Fertilizer Granulator

technical field

The utility model relates to the technical field of granulation, in particular to a granulation device for fertilizers.

Background technique

Organic fertilizers generally go through the granulation stage. Fertilizer granulation methods mainly include: extrusion method (that is, extrusion or roller granulation), agglomeration method (that is, disc or cylinder granulation), and melt method (that is, high temperature granulation). pelletized after melting). Compared with chemical fertilizers of the same composition, the extrusion method is the simplest, and the cost and price are lower, but the granules obtained by the extrusion method are relatively low in strength and easy to scatter; The strength is relatively high, but the granulation speed of the pellet method is slow and the area is large; the fertilizer granules produced by the melt method have the highest strength and the most expensive price.

Existing granulators that adopt the extrusion method for granulation are mainly divided into extrusion granulation and roller granulation. Extrusion granulation is to cut into strips after being extruded into strips to obtain a fertilizer granule with irregular shape. Generally, after this granulation method is adopted, the irregular granules need to be sent to the disc granulator again for further processing. Secondary granulation. Double-roll granulation is to directly extrude the material into a spherical shape, but the strength of the granules produced by this granulation method is low, and the feeding of the existing double-roll granulator is not uniform, resulting in the obtained granules with different strengths. one.

Utility model content

The purpose of the utility model is to provide a fertilizer granulation device with low cost, high fertilizer granule strength and uniform strength in order to solve the above-mentioned technical problems.

The technical solution adopted by the utility model for solving the above-mentioned technical problems is: the granulation device for fertilizer includes a casing, a feeding device arranged on the upper left side of the casing and a feeding belt inside the casing, and the feeding belt is arranged horizontally Below the feeding device, there are hemispherical grooves evenly distributed on it, a granulation roller is arranged on the right end of the shell, and hemispherical grooves are evenly distributed on the outer roller surface of the granulation roller, the granulation roller and the feeding belt The hemispherical grooves correspond to each other. During the operation, the material is extruded into a spherical shape. There is also a rotating scraper above the feeding belt that can distribute the material on the feeding belt evenly. There are baffles and sieve holes evenly staggered on the material plate, and a waste collection plate for collecting debris falling from the material plate is provided under the material plate, and the left and right ends of the shell are provided with hemispheres for cleaning. A sticky material cleaning device for hemispherical grooves and a drying device for drying hemispherical grooves.

Further, a waste material collecting plate is also arranged below the feeding belt for collecting the fertilizer cleaned up by the sticky material cleaning device.

Further, the distance from the rotating scraper to the feeding belt can be adjusted, which is used to adjust the amount of material conveyed by the feeding belt.

Further, a material outlet is provided at the bottom of the material plate.

Furthermore, the baffle is in a figure-eight or in-line shape.

Furthermore, the screen holes are evenly distributed between the baffles.

The beneficial effects of the utility model are: the utility model is simple in structure and easy to use, and the material on the feeding belt is evenly distributed through the rotating scraper, and after the feeding belt and the granulating roller are extruded, they are constantly collided with the baffle on the material plate , Rolling and sliding, can obtain high-strength fertilizer particles with uniform strength and size, the particles are not easy to scatter, and the scattered materials fall through the sieve holes on the material plate to the waste material collection plate during the friction and collision process of the particles, and can be reused; The new type is equipped with a sticky material cleaning device and a drying device on the left and right ends of the shell, which can clean up the fertilizer stuck in the hemispherical groove and dry the hemispherical groove, so that the material can be dried under its own humidity. It is easier to extrude under the action, and it does not stick to the material. After being extruded into a ball, it is easier to fall from the hemispherical groove.

detailed description

As shown in the figure, the fertilizer granulation device includes a casing 1, a feeding device 2 arranged on the upper left of the casing 1, and a feeding belt 3 inside the casing 1, and the feeding belt 3 is horizontally arranged below the feeding device 2, Hemispherical grooves are evenly distributed on it, the right end of the shell 1 is provided with a granulation roller 4, the outer roller surface of the granulation roller 4 is evenly distributed with hemispherical grooves, the hemispherical grooves on the granulation roller 4 The groove and the hemispherical groove of the feeding belt 3 correspond to each other. During the operation, the two hemispherical grooves cooperate to squeeze the material into a spherical shape. There is also a device above the feeding belt 3 that can distribute the material on the feeding belt 3 evenly. The rotating scraper 5 makes the amount of material falling into the hemispherical groove approximately the same, thereby ensuring uniform particle size and particle strength of the obtained fertilizer. Below the granulation roller 4, there is an inclined material plate 6, on which baffles 601 and sieve holes 602 are uniformly arranged alternately, the baffles 601 are arranged in a straight or eight-shaped shape, and the sieve holes 602 are evenly distributed in the Between the baffle plates 6, below the material plate 6, there is a waste collection plate 8 for collecting scraps falling from the material plate 6, and the bottom of the material plate 6 is provided with a discharge port, and the extruded granular material falls to The material plate 6 and the baffle plate 601 block the whereabouts of the fertilizer particles, so that the fertilizer particles continue to rub and collide slowly along the material plate 6, and the material is discharged from the outlet. loose. Both the left end and the right end of the housing 1 are provided with a sticky material cleaning device 7 for cleaning the hemispherical groove and a drying device 9 for drying the hemispherical groove, which can clean up the fertilizer stuck in the hemispherical groove , and the hemispherical groove is dried, so that the material is easier to extrude under the action of its own humidity, and the material is not sticky, and it is easier to drop from the hemispherical groove after being extruded into a ball.
