Description

Technical Field

[0001] This utility model belongs to the field of fertilizer granulation technology, specifically relating to a granulation device for compound fertilizer production. Background Technology

[0002] Fertilizer granulators, based on their working principles, applicable materials, and production needs, mainly include rotary drum granulators, double-roller extrusion granulators, disc granulators, stirring tooth granulators, columnar extrusion granulators, flat die extrusion granulators, and ring die extrusion granulators. Disc granulators are a common type of fertilizer granulation equipment, but the size of the granules is generally controlled by the rotation speed. However, as the rotation speed decreases, the uniformity of granulation will be inconsistent, leading to uneven fertilization and seedling burn. At the same time, a large amount of dust is generated during granulation, and the faster the granulation efficiency, the more dust is generated, resulting in a very poor workshop environment and seriously affecting the respiratory health of employees.

Detailed Implementation

[0016] The embodiments of this utility model are further described below with reference to the accompanying drawings. Example

[0017] like Figures 1 to 3 As shown; a granulation device for compound fertilizer production includes a base frame 1, an adjusting cylinder 2, a motor 5, a circular rotating plate 7, a V-shaped track ring 8, a stabilizing device 9, a die fixing frame 10, a granulation disc 11, a dust cover 12, adjusting bolts 15, and a height positioning device. One end of the die fixing frame 10 is hinged to the base frame 1. One end of the adjusting cylinder 2 is hinged to the base frame 1, and its piston rod is hinged to the die fixing frame 10. The height positioning device is hinged at both ends to the base frame 1 and the die fixing frame 10, respectively. The motor 5 is mounted on the die fixing frame 10 and provides power. The rod is connected to the circular rotating plate 7, the V-shaped track ring 8 is connected to the circumference of the circular rotating plate 7, several stabilizing devices 9 are installed on the orifice fixing frame 10 and are rotatably connected to the V-shaped track ring 8, the granulation disc 11 is connected to the circular rotating plate 7, the dust cover 12 is connected to the orifice fixing frame 10 by several adjusting bolts 15, and adjusting nuts are fitted on the adjusting bolts 15. The dust cover 12 is provided with a dust suction pipe 13, a feeding port 14 and a nozzle, and a discharge port 16 is opened on the dust cover 12; the height positioning device includes a positioning... The system comprises a positioning tube 3, a telescopic rod 6, and positioning bolts. One end of the positioning tube 3 is hinged to the base frame 1, and one end of the telescopic rod 6 is hinged to the orifice-shaped fixing frame 10, with the other end positioned inside the positioning tube 3. The positioning tube 3 and the telescopic rod 6 have several positioning holes 4 for the insertion of positioning bolts. The stabilizing device 9 includes a connecting seat 17, a dovetail slider 18, a fixed shaft 19, and a track wheel 110. The connecting seat 17 has a dovetail groove through which the dovetail slider 18 slides. The fixed shaft 19 is connected to the dovetail slider 18 and to the track wheel 110. A bolt is connected to the receiving seat 17 to fix the dovetail slider 18; a frame 111 is installed inside the dust cover 12, and an adjusting scraper is installed on the frame 111; the adjusting scraper includes a scraper spring 112, a sliding column 113, a slide frame 114 and a scraper 116, one end of the two sliding columns 113 is connected to the frame 111 and the other end is connected to a positioning block 115, the scraper spring 112 is sleeved on the sliding column 113 and is located between the frame 111 and the slide frame 114, and the slide frame 114 is slidably connected to the sliding column 113 and connected to the scraper 116.

[0018] The hydraulic cylinder drives one end of the orifice fixing frame 10 to lift and lower, thereby controlling the tilt angle of the granulation disc 11. The motor 5 drives the circular rotating plate 7 to rotate, which in turn drives the granulation disc 11 to rotate, causing the material inside the granulation disc 11 to tumble. Fertilizer powder raw materials are introduced through the feeding port 14, and dust produced during granulation is sucked out through the dust suction pipe 13. Simultaneously, liquid is introduced through the nozzle. The granulated fertilizer particles roll out through the discharge port 16. A certain gap exists between the dust cover 12 and the granulation disc 11, which is adjusted by adjusting the adjusting nut and adjusting the adjusting bolt 15. As the circular rotating plate 7 rotates, several track wheels 110 of the stabilizing devices 9 provide support. In conjunction with the V-shaped track ring 8, the stability of the rotation of the circular rotating plate 7 after the granulation disc 11 changes angle is ensured. The position of the dovetail slider 18 is adjusted by loosening the bolts, so that the tightness of the contact between the track wheel 110 and the V-shaped track ring 8 is controlled. After the hydraulic cylinder adjusts the angle of the die-shaped fixing frame 10, the positioning bolts are inserted into the positioning holes 4 on the positioning tube 3 and the telescopic rod 6 to ensure the tilt state of the die-shaped fixing frame 10. If it is necessary to continuously change the tilt angle of the die-shaped fixing frame 10, it is not necessary to insert the positioning bolts. When the scraper 116 contacts the bottom of the granulation disc 11, the scraper spring 112 controls the contact force between the scraper 116 and the granulation disc 11 to avoid the scraper 116 rigidly contacting the granulation disc 11.
