Embodiment 1

[0056] Such as figure 1 Shown, a kind of fertilizer cooling method comprises the steps:

[0057] (1) Anti-caking treatment is performed on the fertilizer granules coming out of the granulation device. The temperature of the fertilizer granules coming out of the granulation device is 75°C, and the temperature of the fertilizer granules after anti-caking treatment is 73°C;

[0058] (2) The fertilizer granules after anti-caking treatment are transported into the first-level cooling tank through the conveying equipment for the first cooling and cooling, and the temperature of the cooled fertilizer granules drops to 56°C;

[0059] (3) Carry out a warehouse dump: the fertilizer particles in the primary cooling tank are transported into the secondary cooling tank through the conveying equipment;

[0060] (4) The fertilizer granules are cooled for the second time in the secondary cooling tank, and the temperature of the cooled fertilizer granules drops to 46°C;

[0061] (5) Carrying...

Embodiment 2

[0066] A fertilizer cooling method, comprising the steps of:

[0067] (1) Anti-caking treatment is performed on the fertilizer granules coming out of the granulation device. The temperature of the fertilizer granules coming out of the granulation device is 60°C, and the temperature of the fertilizer granules after anti-caking treatment is 58°C;

[0068] (2) The fertilizer granules after anti-caking treatment are transported into the cooling tank through the conveying equipment for the first cooling and cooling, and the cooled fertilizer granules are cooled to 50°C;

[0069] (3) Carry out a warehouse dumping: through the conveying equipment, the fertilizer particles cooled for the first time are transported from the discharge port to the feed port of the cooling tank, and the fertilizer particles enter the cooling tank again;

[0070] (4) The fertilizer granules are cooled for the second time in the cooling tank, and the cooled fertilizer granules are cooled to 43°C;

[0071] ...

Embodiment 3

[0077] Such as figure 2 Shown, a kind of fertilizer cooling device, described device comprises cooling groove, and cooling groove top is provided with feeding port 1, and cooling groove bottom is provided with discharge port 2, and the bottom of described cooling groove is a cone, and the cone angle of cone is 60 °, the inside of the cooling tank is provided with 3 isolation plates 4, and the 3 isolation plates 4 are vertically arranged and parallel to each other. The 3 isolation plates 4 divide the inside of the cooling tank into 4 blanking channels in the horizontal direction. The distance between the top and the top of the cooling tank is 1 meter, the bottom extends to the middle of the cone, and the distance between the bottom and the inside of the cone is 1 meter.

[0078] The feed port 1 and the discharge port 2 of the cooling tank are respectively connected with the conveying pipes of the conveying equipment, so as to facilitate the conveying of the fertilizer particle...

Abstract

The invention provides a fertilizer cooling method. The fertilizer cooling method comprises cooling granular fertilizer through more than one cooling tank, conveying the cooled granular fertilizer to bulk tanks for storage or packing storage, during the cooling process, taking the granular fertilizer out of storage for sunning, and during the sunning process, the granular fertilizer is insulated from outside air. The fertilizer cooling method reduces energy consumption, saves the costs, improves the quality of the fertilizer and avoids generating waste gas. The invention also provides a fertilizer cooling device. The fertilizer cooling device comprises the cooling tanks, the top of every cooling tank is provided with a feeding port, the bottom of the cooling tank is provided with a discharge port and is of a cone shape, and the inside of every cooling tank is provided with more than one isolation board which horizontally divides the inside of the cooling tank into a plurality of blanking channels. The fertilizer cooling device enlarges the contact area between the granular fertilizer and the cooling tanks and can effectively avoid 'arches' formed by the granular fertilizer.

Description

technical field [0001] The invention relates to a fertilizer cooling method and a cooling device. Background technique [0002] In the prior art, the temperature of fertilizer granules is generally higher after the granulation and drying steps, especially the fertilizer granules obtained by high tower granulation, spray granulation or disc granulation, etc., the temperature is generally at 60- The temperature is about 80°C, so it is necessary to cool the fertilizer granules before performing surface treatment, packaging and other steps. [0003] In the prior art, fertilizer granules are generally cooled by cooling equipment such as a cooling cylinder or a fluidized bed. For example, the patent application with the existing application number 201220313608.6 discloses a fertilizer cooling device. The cooling device includes a cooling box, and a plurality of air intake pipes are installed on the upper wall of the cooling box. The outer wall of the air intake pipe is provided w...
