Embodiment 1

[0023] Embodiment 1: Melt compound fertilizer rotary spray granulation device, the granulation spray plate 10 is fixed on the lower end of the hollow main shaft 4 and driven by the hollow shaft 4 to rotate, the feeding box 7 is set on the hollow shaft 4, and its upper part is connected with the transmission Mechanism 3 is connected, the opening at the lower part is directly facing the granulation spray plate 10, the outlet of the feed pipe 5 of the seed crystal particle material is connected with the feed box 7, the transmission mechanism 3 is set on the hollow shaft 4 and drives the hollow shaft to rotate, and the current collection The slip ring 2 is located on the top of the hollow shaft 4, the supply box 8 is set on the supply box 7, the opening at the lower part is directly facing the granulation spray plate 10, and the outlet of the molten liquid material feeding pipe 6 is connected with the supply box 8 . The lower end surface of the granulation spray disk 10 is provide...

Embodiment 2

[0024] Embodiment 2: On the basis of Embodiment 1, the melt compound fertilizer rotary spray granulation device can be installed at the center of the top of the granulation tower.

Embodiment 3

[0025] Example 3: On the basis of Examples 1 and 2, the principle and method of encapsulating and growing small particles as seeds: the black solid arrows and horizontally arranged dashes in Figure 3 represent the melt, and the hollow The array of arrows and small dots represents small seed crystal particles. The feed box 7 of the small seed crystal particles is located in the inner circle of the melt supply box 8. When the small seed crystal particles fall into the granulation chamber of the heated horizontal rotating body When it is on the end face of the spray plate 10, it will quickly slide to the outer edge of the spray plate 10 under the action of centrifugal force. At this time, it will inevitably touch the liquid that has leaked from the melt feed box 8 to the end face of the granulation spray plate 10. Melt, due to centrifugal force, the molten liquid on the end surface of the granulation spray plate 10 and the small particle material of the seed crystal stay on the en...

Abstract

The present invention relates to a chemical palletizing equipment and its method. In particular, it is a method for pelletizing high-viscosity melt and coating small-diameter granule so as to make its grain size be enlarged. Said invention is a rotary spray-type palletizing equipment, said equipment is formed from the following components: palletizing spray disk, hollow main shaft, feeding box, driving mechanism, material inlet and material outlet, etc.

Description

Technical field: [0001] The invention relates to a chemical granulation device and method, especially suitable for granulation of high-viscosity melts and a method for wrapping small-diameter particles to increase the diameter of the ball, and belongs to the field of chemical granulation equipment. Background technique: [0002] At present, there are many mature technologies in fertilizer granulation. For example, in the traditional urea granulation process, the tower melt method spray granulation is the most used; in the traditional compound fertilizer granulation process, the agglomeration method is the most used. Granulation and more. [0003] Usually, we use low-melting chemical materials with a melting point below 300°C, which are solid at room temperature and liquid at molten state and have flowability. After heating and melting, use special equipment to melt the liquid The material directly enters the refrigerant in the form of droplets. The refrigerant can be a gas ...
