Embodiment 1

[0024] see Figure 1-3 , this embodiment provides a compound fertilizer steam granulation cooling device, including a base 8, a material cylinder 4 located above the base 8, and a drive assembly installed on the upper part of the base 8 for driving the material cylinder 4 to rotate As well as a cooling assembly for cooling the material inside the barrel 4, the upper part of the base 8 is also provided with two sets of support assemblies symmetrical to the drive assembly, and one end of the barrel 4 is provided with a feed port 16 , the other end is provided with a discharge port 7, specifically, the drive assembly includes a motor 12 fixedly arranged on the upper part of the base 8 and a gear 9 connected to the output end of the motor 12 through a rotating shaft 10, the barrel 4 The outer wall is fixedly provided with an annular rack 6, and the gear 9 meshes with the annular rack 5; An air channel 17 , the output end of the fan is connected to the air inlet channel 17 through...

Embodiment 2

[0036] see figure 1 , a steam granulation cooling device for compound fertilizer. Compared with Embodiment 1, this embodiment is provided with a first support plate 11 on the upper part of the base 8, and the rotating shaft 10 runs through the first support plate 11 and is connected with the first support plate 11 The first support plate 11 is rotatably fitted by a bearing.

[0037] The embodiment of the present invention has the advantages of high production efficiency and good cooling effect of material particles. The material cylinder 4 is supported above the base 8 by two sets of supporting components, and the motor 12 is used to drive the rotating shaft 10 to rotate, which in turn drives the gear 9 to rotate. 9 meshes with the ring rack 5, the gear 19 drives the barrel 4 to rotate through the ring rack 5, the compound fertilizer raw material enters the inside of the barrel 4 from the feed port 16, and is compounded by the special structure (not shown) inside the barrel 4....

Abstract

The invention provides a compound fertilizer steam granulation cooling device. The invention belongs to the technical field of compound fertilizer production, and the cooling device includes a base, acharging barrel that is located above the base, the driving assembly that is installed on the upper portion of the base and used for driving the charging barrel to rotate, and the cooling assembly that is used for cooling material particles in the charging barrel. The upper portion of the base is further provided with two sets of bearing assemblies which are symmetrical about the driving assembly. A feeding port is formed in one end of the charging barrel, a discharging port is formed in the other end of the charging barrel, the driving assembly comprises a motor fixedly arranged on the upperportion of the base and a gear connected with the output end of the motor through a rotating shaft; an annular rack is fixedly arranged on the outer wall of the charging barrel, and the gear is meshed with the annular rack. The cooling assembly comprises a draught fan fixedly installed outside the charging barrel and an air inlet channel formed in the inner wall of the charging barrel. The embodiment of the invention has the advantages of high production efficiency and good particle cooling effect.

Description

technical field [0001] The invention belongs to the technical field of compound fertilizer production, in particular to a compound fertilizer steam granulation cooling device. Background technique [0002] Drum granulator is a molding machine that can make materials into specific shapes. Drum granulator is one of the key equipment in the compound fertilizer industry, suitable for cold and hot granulation and large-scale production of high, medium and low concentration compound fertilizers. The main working method is granulation wet granulation. Through a certain amount of water or steam, the basic fertilizer is fully chemically reacted after the humidity is adjusted in the cylinder. Under certain liquid phase conditions, the rotation of the cylinder makes the material particles Generate extrusion force to agglomerate into balls. [0003] At present, when the drum granulator is granulating, due to the high temperature inside the barrel, it needs to be naturally cooled befor...
