Problems solved by technology
[0004] The purpose of the present invention is to solve the shortcomings in the prior art, such as: 1. Generally, the liquid raw materials need to be mixed during granulation, and the solid raw materials need to be crushed easily when they are agglomerated. Under the double requirements, the requirements for process coordination are relatively high, such as Incomplete crushing or mixing will lead to insufficient strength of the granulated product, which will affect normal use; 2. More dust will be generated during granulation, which will affect the health of nearby workers; 3. The diameter of the material after granulation is prone to error, It is inconvenient to recycle the screened materials, which causes a certain amount of waste and cannot meet the needs of use well. A fertilizer granulation device and granulation process with dust suppression function is proposed

Embodiment approach
[0053] The implementation method is as follows: when granulation produces a lot of dust, the flushing liquid can be pumped through the flushing main pipe 602, and the flushing liquid impacts into the crushing box 405 through the flushing branch pipe 601 to avoid adhesion in the crushing box 405, and at the same time, the flushing liquid passes through the bottom The connecting main pipe 603 flushes to the top of the granulation roller 403 through the bottom nozzle 604, so that the dust can be covered by flushing and flow into the bottom box 1, and the raw material mixture can be used for flushing, so as to prevent the flushing water from affecting the mixing and granulation effect. Prevent flying dust from flying outward through the crushing box 405 and the feeding pipe 301, effectively ensure the cleanliness of the surrounding environment, and avoid affecting the health of nearby workers.

The invention discloses a fertilizer granulating device with a dust falling function and a granulating process, and relates to the technical field of fertilizer production. The fertilizer granulatingdevice comprises a box body, a material returning mechanism is arranged on one side of an inner cavity of the box body, a feeding mechanism is arranged at the top of the inner cavity of the box body,a granulating mechanism is arranged on one side of the inner cavity of the box body, and a dust falling mechanism is arranged at the top of the granulating mechanism; and a material leaking mechanismis arranged in an inner cavity of the box body, and a material sieveing mechanism is arranged at the bottom of the inner cavity of the box body and located at the bottom of the material leaking mechanism. Through the designed granulating mechanism and feeding mechanism, particles with sieve plate mesh apertures fall into the material receiving plate of the bottom box body, so that raw materials can be crushed or stirred during feeding, the raw material mixing effect after feeding can be improved, the particles can be effectively sieved, and the particle size is prevented from being too large or too small. Meanwhile, the particle size and the discharging width can be adjusted, so that the feeding effect of different diameters can be adapted, the strength of granulated finished products is remarkably improved, and the use requirements are met.
Description
technical field [0001] The invention relates to the technical field of fertilizer production, in particular to a fertilizer granulation device and a granulation process with dust suppression function. Background technique [0002] In agricultural production, fertilizer is an indispensable part. In the period of low productivity in ancient times, fertilizers can only be composted through human excrement to meet the needs of improving soil properties. In modern fertilizer production processes, it has been possible to extract One or more of the nutrients necessary for plants to improve soil properties and soil fertility levels is one of the material bases of agricultural production. In order to absorb changes in fertilizers, fertilizers are generally made into granules to facilitate maintenance . [0003] Chinese Patent Publication No.: CN209155783U discloses a fertilizer granulation device, which relates to the technical field of agricultural production equipment. The fertili...
