Description

An adjustable ring die granulation device for carbon-based fertilizer granules

technical field

The utility model relates to a granulation device, in particular to an adjustable ring die granulation device for carbon-based fertilizer particles.

Background technique

Ordinary fertilizers are easily lost under the action of rainwater during use, and the nutrient utilization rate is low, resulting in a short fertilization cycle and a large amount of fertilizer. Long-term use is likely to induce potential environmental pollution, causing soil compaction, soil quality degradation and other problems. Under the above background, carbon-based fertilizers have gradually come into people's sight. Compared with ordinary fertilizers, carbon-based fertilizers have high stability and high adsorption, which is enough to maintain fertilizer nutrients for a long time and play a slow-release effect. Improve the utilization rate of fertilizer nutrients and reduce the amount of fertilizer per unit area; and use the role of carbon base to maintain nutrients. When producing carbon base fertilizers, trace elements that can promote plant growth can be added to expand the efficacy of fertilizers. During the production and granulation of carbon-based fertilizers, the particle size of the fertilizer has an important impact on the slow-release period of the fertilizer and the nutrient retention effect, and different formulas of fertilizers have different requirements for the particle size. Therefore, there is a need for a granulator that can control the granulation size.

The traditional granulator pays more attention to the efficiency of granulation, and it is difficult to adjust the particle size during the granulation process. Such as the CN103721634A patent announced on April 16, 2014, the Chinese patent is called a double-mode rapid granulator. The device is equipped with a ring mold, one end of the ring mold is fed, and the other end is equipped with a plane mold, the ring mold and the plane mold are evenly distributed with discharge holes, the ring mold is equipped with radial pressure rollers, and the plane mold is equipped with axial Pressing roller, the material is extruded from the discharge hole by the radial pressing roller and the axial pressing roller, and then scraped and granulated by the rotary cutter on the outside of the ring die and the flat die. The cutting knife, radial pressure roller and axial pressure roller of the device are all driven by the main shaft, the action of extruding the material and scraping by the cutting knife is correspondingly unchanged, and the size of the discharged particles is fixed and cannot be adjusted.

Contents of the invention

The purpose of the utility model is to provide a ring die granulation device with adjustable carbon-based fertilizer particles for the problem that the granulation size of the existing ring die granulator cannot be adjusted and is not suitable for the granulation of carbon-based fertilizers.

The technical solution adopted by the utility model to solve the technical problem is: an adjustable ring die granulation device for carbon-based fertilizer particles, including a frame, a ring die is arranged on the frame, and die holes are uniformly distributed on the side wall of the ring die , the inner cavity of the ring die is provided with a number of rolls that roll and fit the side wall of the ring die, the outer side of the ring die is provided with a cutter, the axial side of the ring die is provided with a motor-driven main shaft, and the main shaft and the ring die are provided with a There is a planetary gear mechanism, the planetary gear structure adopts the planet carrier input, the sun gear and the outer ring gear are both output, the main shaft drives the planet carrier input, the sun gear drives the roll output, the outer ring gear drives the ring die output, the sun gear and the Adjustable damping devices are respectively provided on the outer ring gear, and the cutter is fixedly arranged on the frame, and the edge of the cutter fits the outer surface of the ring die. After the carbon-based fertilizer mixture enters the inner cavity of the ring die, it is squeezed by the roll and extruded from the die hole. Under the same conditions, the amount of material extruded by the roll each time is basically stable, while the material extruded from the die hole Scraped under the action of the cutter, when the cutter does not reach the position of the die hole, the material will continue to accumulate and increase until it is scraped off by the cutter or falls off automatically after reaching the limit weight. Therefore, under the premise that the material has not accumulated to the limit weight, the number of times the roller squeezes the material determines the particle size of the final carbon-based fertilizer during the one-week operation of the cutter relative to the ring die, that is, the distance between the ring die relative to the roller and the ring die relative to the cutter. The speed ratio between them determines the particle size of the carbon-based fertilizer. Therefore, this device adopts a structure in which the planetary carrier of the planetary gear mechanism is input, the sun gear and the outer ring gear are respectively output to the ring die and the roll, and the cutter is fixed. The speed of the outer ring gear determines the speed of the ring die relative to the cutter, and the relative speed of the outer ring gear and the sun gear determines the relative speed of the ring die and the roll. Using a damping device to adjust the output speed ratio of the outer ring gear and the sun gear can effectively control The speed ratio between the ring die relative to the roll and the ring die relative to the cutter can control the size of the discharged particles. However, the simultaneous output of the sun gear and the outer ring gear is used, and the rotation direction between the two is the same. Compared with the mode in which the input of the sun gear and the output direction of the planet carrier and the outer ring gear are opposite, although the adjustable range of this scheme is small, the speed The specific adjustment accuracy is high, and the particle size can be adjusted more accurately.

Preferably, each roll is evenly arranged on the circumference, each roll is installed on a roll stand, and the roll stand rotates with the sun gear, and the roll is driven by the roll stand to revolve and rotate along the side wall of the ring die. The roll frame is set in a polygonal star shape, and the number of corners is determined by the number of rolls. The rolls rotate with the roll frame and fit the ring die to roll and extrude the material.

Preferably, parallel gear reduction transmission is adopted between the main shaft and the output shaft of the motor.

Preferably, the damping device is an additional load that can be selectively disengaged or hooked. The damping device is used to control the damping of the two outputs, thereby adjusting the speed ratio between the two. The damping device may also adopt an electromagnetic damping structure such as an excitation coil.

Preferably, a feed auger is provided above the ring die, a feed hopper is provided above one end of the feed auger, and the lower end of the feed auger communicates with the inner cavity of the ring die.

As a preference, the bottom of the ring die is a discharge port, and a rotatable fixed tray is provided below the discharge port, and two lower hoppers are arranged on the upper circumference of the fixed tray, which are respectively a fixed weight lower hopper and a constant volume lower hopper. The hopper and the fixed material tray can be rotated to adjust one of the two lower material ports to be aligned with the discharge port. The outlet can adopt fixed weight packaging and constant volume packaging, and the mode can be selected by rotating the fixed tray.

The utility model adopts the structure of one input and two outputs of the planetary gear, and adjusts the output rotational speed ratio through damping, so that the number of times the roll squeezes the material when the cutter rotates relative to the ring die for a circle can be adjusted, thereby adjusting the output particles of the carbon-based fertilizer. The size is suitable for different granulation requirements of different components of carbon-based fertilizers.
