Embodiment 1

[0042] See eg image 3 In the shown inert atmosphere granulation system, in this specific embodiment, the inert gas source uses 99.999% high-purity argon as the protective gas, and the gas purification device uses copper catalyst gas purification equipment, and connects the feeding system and granulation system respectively. system, exhaust system. Ensure that the water and oxygen index is less than 10ppm, put 20 kg of anhydrous lanthanum bromide powder in the supply tank, raise the temperature to 50°C above the melting point of lanthanum bromide, keep the lanthanum bromide in a liquid state, and then spray it into the inert airflow from the nozzle In the protected condensation tower, adjust the aperture of the nozzle and the flow rate of the cooling air flow to obtain lanthanum bromide particles with a uniform particle size of -10 mesh.

Embodiment 2

[0044] See eg image 3 In the shown inert atmosphere granulation system, in this specific embodiment, the inert gas source uses 99.999% high-purity argon as the protective gas, and the gas purification device uses copper catalyst gas purification equipment, and connects the feeding system and granulation system respectively. system, exhaust system. To ensure that the water and oxygen index is less than 10ppm, put 20 kg of anhydrous cerium bromide powder into the supply tank, raise the temperature to 50°C above the melting point of cerium bromide, keep the cerium bromide in a liquid state, and then spray it into an inert airflow from the nozzle In the protected condensation tower, adjust the aperture of the nozzle and the flow rate of the cooling air flow to obtain cerium bromide particles with a uniform particle size of -10 mesh.

Embodiment 3

[0046] See eg image 3 In the shown inert atmosphere granulation system, in this specific embodiment, the inert gas source uses 99.999% high-purity argon as the protective gas, and the gas purification device uses copper catalyst gas purification equipment, and connects the feeding system and granulation system respectively. system, exhaust system. Ensure that the water oxygen index is less than 10ppm, put 20 kg of anhydrous lanthanum bromide powder and 1.003 kg of cerium bromide powder in the supply tank, raise the temperature to 50 °C above the melting point of lanthanum bromide, and make lanthanum bromide, bromide The cerium remains in a liquid state, and then sprayed into the condensation tower protected by the inert gas flow through the nozzle, and the aperture of the nozzle and the flow rate of the cooling air flow are adjusted to obtain cerium bromide mixture particles with a uniform particle size of -10 mesh and a content of 5% cerium-lanthanum bromide.

Abstract

The invention relates to the technical field of processing systems in the powdery material process and discloses an inert atmosphere granulation system. The inert atmosphere granulation system comprises a feeding device, a granulation device, an inert atmosphere device and an exhaust device, wherein the granulation device comprises a high-temperature spraying granulating machine, a condensing tower and a discharging hole, the high-temperature spraying granulating machine is distributed in the condensing tower, and the discharging hole is formed in the bottom of the condensing tower; the inert atmosphere device comprises an inert gas source and a wind supply pump; the feeding device is connected with the high-temperature spraying granulating machine and is used for conveying materials in the feeding device to the high-temperature spraying granulating machine, the high-temperature spraying granulating machine is used for spraying the materials into the condensing tower, and the inert gas source is in tight connection with an wind inlet of the condensing tower through the wind supply pump and is used for conveying inert gas into the condensing tower so as to granulate the materials sprayed into the condensing tower by the high-temperature spraying granulating machine in an inert gas environment; the exhaust device is used for exhausting waste gas in the condensing tower. By utilizing the inert atmosphere granulation system, the granulation of high-melting-point substances or water and oxygen sensitive powder is realized.

Description

technical field [0001] The invention relates to the technical field of powder material process treatment equipment, in particular to an inert atmosphere granulation system. Background technique [0002] Granulation is an important powder material processing technology and a very critical step in the powder productization process. The purpose is to enhance the uniformity of the material, improve the fluidity of the material, and improve the compressibility of the material. Granulation technology is widely used in chemical fertilizer industry, pharmaceutical industry, plastic industry, etc., and granulation equipment is also very popular. [0003] At present, according to different granulation methods, the existing technologies mainly include the following three most widely used granulation techniques, as follows: [0004] (1) Extrusion granulation technology: the adhesive is mixed with the material powder to prepare a slurry, which is extruded into a wet strip and then knead...
