Embodiment 2
[0038] Same as Embodiment 1, the difference is that the diameter of the second air distribution hole 521 is equal to the diameter of the first air distribution hole 511; the air inlet is externally connected with a blower; the inner wall of the fluidization chamber 1 is symmetrically arranged with The side air outlet 8; the air distribution frame 52 is circular; the spray heat pipe 4 has three, and the first air distribution hole in the cap 512 is five.
Embodiment 3
[0040] Same as the second embodiment, the difference is that there are 6 spray heat pipes 4, and 6 first air distribution holes in the cap 512; a built-in heater 11 is arranged on the inner wall of the fluidization chamber.

The invention relates to a granulation device, particularly to a spray granulation device, which includes a fluidization chamber, an air inlet located at the bottom of the fluidization chamber and an air outlet positioned at the top of the fluidization chamber, and also includes spray heat pipes disposed at the upper part of the fluidization chamber and a wind distributor arranged at the bottom of the fluidization chamber. The spray heat pipes realize material feeding through a first feeding chamber disposed outside the fluidization chamber. The outer side wall of the fluidization chamber is also equipped with a second feeding chamber. The wind distributor consists of a wind distribution frame and wind distribution pipes in evenly spaced and cross arrangement. The net gaps formed by crossing of the wind distribution pipes are discharge ports. The wind distribution pipes are equipped with first wind distribution holes, and realize wind feeding through the air inlet. The device provided by the invention has the advantage of even granulation, difficult accumulation and leakage of materials, and reduced cost.
Description
technical field [0001] The invention relates to a granulation device, in particular to a spray granulation device. Background technique [0002] Spray granulation is a method of using a spray dryer to evaporate the solvent in the slurry droplets to obtain dry powder by means of atomization and heat. The spray drying process is the process in which the slurry passes through the atomizer to quickly dry the slurry droplets into granules. Spray drying is not only widely used in traditional ceramics, organic and inorganic chemicals, powder metallurgy, food, and pharmaceutical industries, but also in various modern electronic and functional ceramic industries. Spray drying has become an important process measure that is indispensable for the preparation of modern oxide ceramics with uniform composition, uniform density of dry-pressed green bodies, and obtaining originals with consistent performance. [0003] For example, when tryptophan is granulated, crystals can act as crystal...
