DETAILED DESCRIPTION

[0027] In order to make the personnel in the technical field better understand the scheme of the present application, the technical scheme in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should belong to the scope of protection of the present application.

[0028] The present application provides an anti-caking agent, which is prepared by mixing raw materials including polyethylene glycol 200, polyethylene glycol 400 and polyethylene glycol 600 under the temperature condition of 70-80℃. The mass percentage of the polyethylene glycol 200, polyethylene glycol 400 and polyethylene glycol 600 is 30:30:60. The raw materials of the anti-caking agent further include a volatile water-soluble surfactant, which includes glycerol and emulsifier. The anti-caking agent of the present application is soluble in water and can avoid causing the blockage of drip irrigation and sprinkler irrigation equipment when the water-soluble fertilizer is used.

[0029] The present application further provides a use method of the anti-caking agent, which includes screening and cooling the fertilizer prepared by the tower process and then adding the fertilizer into a coating device, so that the anti-caking agent is uniformly sprayed on the flat and rolling fertilizer particles.

[0030] Among them, please refer to Figures 1-5The package device comprises a shell 1, a cloth assembly 2 and a liquid spraying assembly 3 which are installed in the shell 1. The shell 1 is internally formed with a top-opened package bin which comprises a cylindrical cloth cavity 11, a circular truncated cone-shaped package cavity 12 and a cylindrical discharge cavity 13 which are sequentially arranged from top to bottom. The diameter of the circular truncated cone-shaped package cavity 12 decreases from top to bottom. The cloth assembly 2 comprises a rotating member 21 and a plurality of spiral strip plates 283. The rotating member 21 is rotationally arranged at the lower half of the cylindrical cloth cavity 11 and can rotate along the central axis of the cylindrical cloth cavity 11. The outer side of the rotating member 21 is formed with a cylindrical surface 22 which is coaxial with the cylindrical cloth cavity 11. An annular gap 23 is formed between the cylindrical surface 22 of the rotating member 21 and the inner wall of the cylindrical cloth cavity 11. A discharge gap is formed between the bottom end of the rotating member 21 and the inner wall of the circular truncated cone-shaped package cavity 12. The plurality of spiral strip plates 283 are uniformly welded on the cylindrical surface 22 of the rotating member 21 in the circumferential direction. The side of the spiral strip plates 283 which is away from the rotating member 21 is tightly attached to the inner wall of the cylindrical cloth cavity 11 so that the annular gap 23 is divided into a plurality of spiral cloth channels 24. The bottom end of the spiral strip plates 283 is further provided with an extension 284 which extends downward and abuts against the inner wall of the circular truncated cone-shaped package cavity 12. The upper side of the spiral strip plates 283 is inclined towards the side of the rotating member 21. The center of the top of the rotating member 21 is inwardly recessed to form a storage recess 25. The liquid spraying assembly 3 is fixedly arranged at the bottom of the rotating member 21 and is used for spraying coating emulsion to the fertilizer in the circular truncated cone-shaped package cavity 12.

[0031] In use, the chemical fertilizer is poured into the storage recess 25. The rotating member 21 is rotated towards the side which is away from the spiral direction. The chemical fertilizer particles in the storage recess 25 are continuously moved towards the edge of the storage recess 25 under the action of centrifugal force and fall out of the storage recess 25. After the chemical fertilizer particles fall out of the storage recess 25, they enter the plurality of spiral cloth channels 24 in the annular gap 23. At this time, the chemical fertilizer particles roll in the spiral cloth channels 24 downwards along the spiral cloth channels 24, i.e. the chemical fertilizer particles roll on the upper side of the spiral strip plates 283. After the chemical fertilizer particles move to the extension 284 of the spiral strip plates 283, the chemical fertilizer particles are discharged from the spiral cloth channels 24 into the circular truncated cone-shaped package cavity 12. At this time, since the chemical fertilizer particles generate initial speed during the rolling process in the spiral cloth channels 24, the chemical fertilizer particles roll downwards along the spiral direction on the inner wall of the circular truncated cone-shaped package cavity 12 after entering the circular truncated cone-shaped package cavity 12. In this process, the chemical fertilizer particles are laid on the inner wall of the circular truncated cone-shaped package cavity 12. The coating emulsion is sprayed to the surface of the chemical fertilizer particles by the liquid spraying assembly 3 so that the chemical fertilizer particles are coated with a layer of anti-caking agent film. After the chemical fertilizer particles are coated with the anti-caking agent film, they enter the cylindrical discharge cavity 13 and are discharged.

[0032] The effects of the above process are described in detail as follows.

[0033] 1. The present application can make the fertilizer continuously and uniformly move outward in the storage groove 25 and drop into the annular gap 23 by the rotation of the rotating member 21, and the rotation speed of the rotating member 21 is controlled to adjust the discharge amount of the fertilizer particles, so as to avoid the accumulation of the fertilizer in the circular cone-shaped coating cavity 12.

[0034] 2. In the present application, when the fertilizer particles roll in the spiral material distribution channel 24, the fertilizer particles move towards the side of the rotating member 21 due to the upward side of the spiral strip plate 283 being inclined towards the side of the rotating member 21, but since the spiral strip plate 283 is fixed on the rotating member 21, the spiral strip plate 283 will also rotate with the rotating member 21, and under the action of centrifugal force, the fertilizer particles can be laid on the upward side of the spiral strip plate 283, so that the fertilizer particles can be quickly laid on the inner wall of the circular cone-shaped coating cavity 12 after being discharged from the spiral material distribution channel 24, thereby improving the coating effect of the fertilizer particles.

[0035] 3. In the present application, since the extension part 284 of the spiral strip plate 283 is in contact with the inner wall of the circular cone-shaped coating cavity 12, a sharp end is formed at the top of the circular cone-shaped coating cavity 12, and when the fertilizer particles laid on the upward side of the spiral strip plate 283 are discharged, the fertilizer particles close to the cylindrical material cavity 11 will first contact the inner wall of the circular cone-shaped coating cavity 12, at this time, the extension part 284 will block the fertilizer particles close to the cylindrical material cavity 11, but since the rotating member 21 rotates towards the side away from the spiral direction of the spiral strip plate 283, that is, the extension part 284 of the spiral strip plate 283 will retreat, thereby avoiding blocking the fertilizer particles.
