Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0031] Referring Figure 1 and Figure 3 , an embodiment provided by the present utility model: A device for the production of loose fiber flame-retardant cotton, including a reaction kettle 1. The left side of the top wall of the reaction kettle 1 is communicated with an air tank 3. The left side of the bottom of the air tank 3 is communicated with a connecting pipe 4. The bottom of the connecting pipe 4 is communicated with a heater 5. The bottom of the heater 5 is communicated with an inlet pipe 6. The right side of the bottom of the air tank 3 is communicated with a condenser 7. The bottom of the condenser 7 is communicated with a separator 8. The middle and lower part of the front side of the outer wall of the separator 8 is communicated with a thin pipe 9. The other end of the thin pipe 9 is communicated with a recovery cylinder 10. The right side of the top wall of the reaction kettle 1 is communicated with an ammonia regulating mechanism 2 for regulating ammonia; a gasket 11 is installed on the top of the reaction kettle 1, and a kettle cover 12 is installed on the top of the reaction kettle 1;
[0032] Specifically, air is introduced through the inlet pipe 6, and the heater 5 is used to effectively heat these gases to reach the required reaction conditions. The condenser 7 cools the air. The gas-liquid mixture in the air will be guided to the separator 8. Under the action of this device, the liquid and gas in the air will be effectively separated. The separated liquid part will be collected again for subsequent use. The collected liquid will be stored in the recovery cylinder 10. When these liquids are needed, they can be directly taken from the inside of the recovery cylinder 10, so as to realize the recycling and efficient management of resources. The reaction kettle 1 can be sealed through the gasket 11 to prevent gas leakage.
[0033] Referring Figure 2 and Figure 4 , the ammonia regulating mechanism 2 includes a storage tank 201, which is communicated with the right side of the top wall of the reaction kettle 1. The middle and lower part of the left side of the outer wall of the storage tank 201 is communicated with a pipeline 202. The top of the outer wall of the pipeline 202 is rotatably connected with a stop valve 203. The bottom of the pipeline 202 is communicated with a metering pump 204. The bottom of the metering pump 204 is communicated with a pipeline 205. The bottom of the outer wall of the pipeline 205 is rotatably connected with a check valve 206.

[0039] Working principle: During the reaction process, air enters through the intake pipe 6, the heater 5 heats the gas, the condenser 7 cools the used air, the separator 8 separates the gas and liquid in the air, enabling the liquid in the air to be collected again, and the recovery cylinder 10 stores the liquid, which can be taken from inside the recovery cylinder 10 during use;
[0040] When adjusting ammonia gas, first use the storage tank 201 to store ammonia gas. Control the flow rate of ammonia gas through the stop valve 203 at the top of the first pipeline 202.
