Embodiment

[0022] Embodiment: a kind of shotcrete rotary granulator that is used to coat the charcoal layer outside granular fertilizer, such as Figure 1 to Figure 4 shown. The device includes a coaxially arranged horizontal outer cylinder 3 and an inner cylinder 4, the inner cylinder 4 and the outer cylinder 3 rotate synchronously, and the left end of the inner cylinder 4 is provided with an air chamber communicating with the inner cylinder 4, and the air chamber is also provided with An air inlet 10 is arranged, and other places of the air chamber are all closed. The left end of the inner cylinder 4 is also provided with a feed inlet 1 and a spray gun 2, both of which pass through the air chamber to communicate with the outside, and are sealed at the penetrations, and the feed inlet 1 is used to add to the inner cylinder 4. Granular fertilizer and charcoal powder to be coated, spray gun 2 is used for spraying binder.

Abstract

The invention relates to a granulator, in particular to a double-layer barrel-shaped slurry-spraying rotary granulator. The device comprises an inner barrel and an outer barrel, which are arranged coaxially and opposite in conveying directions, and is characterized in that: one end of the inner barrel is provided with a feed inlet and the other end of the inner barrel is communicated with the outer barrel; an air inlet is formed on one side of the feed inlet of the inner barrel; the opening on the other side of the inner barrel is communicated with the outer barrel; an air outlet is formed on the outer barrel on the opening side of the inner barrel; and thus, a drying air duct running through the inner barrel is formed. In the invention, grain finishing and drying can be performed in a granulating process, a plurality of processes are performed in one machine, process steps are reduced, the production efficiency is improved and the production cost is reduced; and grain finishing is performed in the interlayer between the inner barrel and the outer barrel, the drying heat can be reused, energy consumption is reduced, and external working environment is improved.

Description

technical field [0001] The invention relates to a granulator, in particular to a double-layer cylindrical spraying rotary granulator. technical background [0002] Some materials that are granular in themselves need to be coated with a layer of other substances on the surface of the material. Generally, spray granulation is used, and the granular material and the coating are fully stirred and mixed to ensure uniform coating and good particle size. When the coating is completed, the material needs to be dried to make the coating more stable, and the final product should have good roundness. [0003] The CN101492328A patent application document disclosed by the Chinese Patent Office on July 29, 2009 is titled a horizontal drum granulator suitable for high water content organic fertilizers. The machine base of the device is provided with a rotating cylinder driven by a power transmission system. The characteristic is that the rotating cylinder adopts a double rotating cylinder...
