Embodiment 1

[0042] Such as figure 1 As shown, a fertilizer drying and dehydrating device includes a drum 1, an air supply structure, a power structure and a support structure. Such as figure 2 As shown, the central axis of the drum 1 is horizontal, and the drum 1 includes a drum side wall 20 and a drum bottom wall 21 located at two ends of the drum side wall 20 . Such as figure 1 and figure 2 As shown, the side wall 20 of the drum is provided with a feeding port, and a feeding cover 8 is fixed on the feeding port by screws. In this embodiment, the number of the feeding port and the feeding cover 8 is two. On the drum bottom wall 21 on the right side, a discharge port 22 is provided (the discharge cover is not shown, specifically a steel plate is fixed on the outside of the drum bottom wall 21 by screws), and the discharge port 22 is arranged near the feed cover 8. A number of air outlets (diameter 1cm) are provided on the side wall 20 of the drum to ensure that the gas evaporated du...

Embodiment 2

[0049] This embodiment is basically the same as Embodiment 1, the difference lies in the arrangement of the air branch pipe 24, such as Figure 6 As shown, the air branch pipes 24 are no longer located on the same plane, but are interlaced with each other to increase the uniformity of the contact between the air and the material and increase the drying efficiency. Specifically: in this embodiment, the wind branch pipe 24 is divided into three types: wind branch pipe I, wind branch pipe II and wind branch pipe III. Air branch pipe Ⅰ is arranged vertically, air branch pipe II is inclined to the lower left, and air branch pipe III is inclined to the lower right. From left to right (with figure 2 The orientation of the wind branch pipes 24 (there are 12 wind branch pipes 24 in this embodiment, respectively 4 wind branch pipes I, 4 wind branch pipes II and 4 wind branch pipes III) are distributed in the order of wind branch pipes I, wind branch pipes Ⅱ, wind branch pipe III, win...

Embodiment 3

[0052] This embodiment is improved on Embodiment 1 or Embodiment 2, and the point of improvement is that on the basis of Embodiment 1 or Embodiment 2, an auxiliary discharge structure is added. Because the rotating drum 1 is relatively deep, after finishing the drying of the fertilizer, it is necessary to solve the problem of how to take out the dried fertilizer smoothly. Such as Figure 7 As shown, the discharge auxiliary structure includes a connecting rod 27 and two inner rings 26 . The structure of the inner ring 26 is as Figure 8 As shown, a partition 29 is integrally formed on the inner ring 26, and the partition 29 is used to push materials better. Such as Figure 7 As shown, a connecting rod 27 is welded and fixed on the side of the inner ring 26 away from the partition 29 , and the outer surface of the inner ring 26 is in contact with the inner surface of the drum side wall 20 . The connecting rod 27 is welded with a handle 28 after passing through the bottom wal...

Abstract

The invention relates to the technical field of fertilizers, in particular to a quick-acting organic fertilizer and a preparation method thereof. The preparation method of the quick-acting organic fertilizer sequentially comprises the following steps: a mixture preparation step: soaking crushed straws with livestock and poultry urine, and then taking the straws which fully adsorb the livestock and poultry urine to obtain a mixture; an anaerobic fermentation step: performing anaerobic fermentation on the mixture to obtain a mixture after anaerobic treatment; and a dehydration step: loading the mixture subjected to anaerobic treatment into special drying equipment, and carrying out dehydration treatment by controlling the temperature at 30-60 DEG C to obtain the quick-acting organic fertilizer. The organic fertilizer obtained by the scheme can solve the technical problems that the existing chemical fertilizer is incomplete in nutrition and damages the soil environment and the existing organic fertilizer is too low in fertilizer efficiency. According to the organic fertilizer, livestock and poultry urine and straw are fully and comprehensively utilized, the problem of environmental pollution is solved, and the organic fertilizer has a good application prospect.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a quick-acting organic fertilizer and a preparation method thereof. Background technique [0002] The nutrient elements in the fertilizer are in a state that can be directly absorbed by plants, and this kind of fertilizer is called quick-acting fertilizer. If the nutrient elements in the fertilizer cannot be directly absorbed by plants, this kind of fertilizer is called a slow-acting fertilizer. After the slow-acting fertilizer is applied, it needs to be decomposed and transformed to provide effective nutrients for crops. For example, chemical fertilizers such as ammonium bicarbonate, ammonium sulfate, diammonium phosphate, ammonium nitrate, and potassium dihydrogen phosphate can all be dissolved in water and are in an ion state, which can be directly absorbed by plants, and they all belong to the category of quick-acting fertilizers. Almost all organic fertilizers (such as ...
