Description

Technical Field

[0001] This utility model relates to the technical field of granulation equipment, and in particular to the technical field of integrated granulation, drying and screening equipment. Background Technology

[0002] Granulators are commonly used for granulating organic, inorganic, and compound fertilizers to facilitate transportation, storage, and application. Traditional granulation equipment uses a planar layout, with granulation, drying, and screening equipment arranged on the same plane to complete the processes. This layout occupies a large area and requires numerous interconnected pieces of equipment. Furthermore, the fixed angles of the granulation and drying equipment cannot meet the granulation needs of various material properties. Summary of the Invention

[0003] The purpose of this invention is to solve the problems in the existing technology and to propose an integrated granulation, drying and screening equipment with a three-dimensional layout, which saves space and allows the granulator angle to be adjusted to meet various granulation needs.

[0004] To achieve the above objectives, this utility model proposes an integrated granulation, drying, and screening equipment, including a frame on which a granulator and a dryer are mounted. The granulator is located above the dryer, and its output end is connected to the input end of the dryer via a chute or conveyor. The tail end of the dryer is equipped with a screening device, and the equipment also includes a dust removal mechanism, the input end of which is connected to both the granulator and the dryer.

[0005] An angle adjustment mechanism for adjusting the tilt angle of the granulator is also provided between the granulator and the frame. The angle adjustment mechanism includes a hinge and a lifter. One end of the granulator is hinged to the frame through the hinge, and the other end is provided with a lifter for adjusting the height of that end.

[0006] Preferably, the granulator also includes a lifting and feeding mechanism for feeding materials into the granulator, wherein the horizontal height of the input end of the lifting and feeding mechanism is below that of the input end of the granulator.

[0007] Preferably, the lifting and feeding mechanism is a belt conveyor or an elevator.

[0008] Preferably, the dust removal mechanism is a cyclone dust collector or / and a spray tower dust collector.

[0009] Preferably, the dryer includes a cylindrical drying drum, a rotary drive mechanism for driving the drying drum to rotate about its axial direction, and a drying component for inputting heat energy into the drying drum. The drying drum is inclined, and the screening device is a screen section located at the lower end of the horizontal height of the drying drum.

[0010] Preferably, a damper is provided in the pipeline between the dust removal mechanism and the granulator.

[0011] Preferably, the lifting device is any one of a manual screw jack, an electric screw jack, and a hydraulic cylinder.

[0012] The beneficial effects of this utility model of an integrated granulation, drying, and screening equipment are as follows: This utility model adopts a three-dimensional layout, arranging the granulator and dryer in layers, saving space and reducing the equipment footprint. By combining the granulator and dryer, the granulated material can be directly fed into the dryer for drying, resulting in a faster process flow and more complete connection between the front and rear of the equipment. A dust removal mechanism is set up to perform dust removal operations on the granulator and dryer respectively, and to perform induced draft operation on the dryer. By setting an angle adjustment mechanism under the granulator, the height of one end of the granulator can be adjusted through a lifting device to adjust the tilt angle of the granulator, thereby meeting the granulation requirements of different materials.

This embodiment adopts a three-dimensional layout, arranging the granulator 1 and the dryer 2 in layers, saving space and reducing the equipment footprint. By combining the granulator 1 and the dryer 2, the granulated material can be directly fed into the dryer for drying, resulting in a faster process flow and more seamless equipment integration. The dust removal mechanism 3 can perform dust removal operations on both the granulator 1 and the dryer 2, and also provide induced draft to the dryer 2.

The angle adjustment mechanism includes a hinge 5 and a lifter 6. One end of the granulator 1 is hinged to the frame 4 via the hinge 5, and the other end is provided with a lifter 6 for adjusting the height of that end. The upper and lower ends of the lifter 6 are respectively hinged to the granulator 1 and the frame 4. By adjusting the height of one end of the granulator 1 through the lifter 6, the tilt angle of the granulator 1 can be adjusted to meet the granulation requirements of different materials.

This integrated design eliminates the need for a separate screening device.
