Embodiment Construction

[0026] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0027] Such as Figure 1 to Figure 2 Shown, a kind of chemical fertilizer production process of the present invention, this process step is as follows:

[0028] S1: Put urea, nitrogen, phosphorus and potassium, sulfur and dicyandiamide nitrogen and phosphorus mixture and starch into a mixer for raw material mixing;

[0029] S2: Add 20% to 30% water to the mixed material in S1, and stir again to make the material a semi-wet solidification; the material can be fully mixed after adding water and evenly stirred, and it is suitable for dry and wet, so it is convenient for the granulator Granulation, which improves the working efficiency of the granulator;

[0030]S3: Send the coagulation in S2 into the granulator for pressing and granulation; install...

Abstract

The invention belongs to the technical field of chemical fertilizer production, in particular to a chemical fertilizer production process. A granulator used in the process comprises a work box, a base, a controller and a pillar. The controller controls the automatic operation of the granulator. An extrusion module is disposed in the work box. The extrusion module comprises a motor, a rotating roller, No. 1 sliding blocks, a sliding shaft, a No. 2 sliding block, a pressing rod, a balancing weight and a guide rail, wherein the sliding shaft is horizontally mounted on the inner roof of the work box; two No.1 sliding blocks are slidably connected to the sliding shaft; the No. 2 sliding blocks are both hinged to the No.2 sliding block through a connecting rod; the No.2 sliding block is slidablyinstalled in the guide rail, which is fixedly installed on the bottom of the work box; and the balancing weight is hinged between the two No.1 sliding blocks through two struts. After materials are mixed by using an agitator, an appropriate amount of water is added for stirring to prepare a solidified material, thus facilitating the granulation of the granulator. And then, the chemical fertilizerproduction efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of chemical fertilizer production, in particular to a chemical fertilizer production process. Background technique [0002] Chemical fertilizers play a pivotal role in agricultural production. As a large agricultural country, my country has a high demand for chemical fertilizers in agricultural production. According to statistics, chemical fertilizers have become the largest material investment in agricultural production, accounting for about 50% of all productive expenditures. my country's fertilizer output and usage are the first in the world, of which the output accounts for about 20% of the world's chemical fertilizer output, and the usage has accounted for 28% of the world's chemical fertilizer consumption. [0003] There have also been some technical solutions for fertilizer granulators in the prior art. For example, a Chinese patent with application number 2017218086612 discloses a fertilizer granula...
