Sodium thiocyanate is a white orthorhombic crystal or powder. It is easy to deliquesce in the air and produces toxic gases when exposed to acid. Soluble in water, ethanol, acetone and other solvents. The aqueous solution is neutral, and the iron salt forms a blood-colored iron thiocyanate, which does not react with the ferrous salt. The concentrated sulfuric acid produces yellow sodium hydrogen sulfate, which reacts with the cobalt salt to form dark blue cobalt thiocyanate, and silver salt or The copper salt acts to form a white precipitate of silver thiocyanate or a precipitate of black copper thiocyanate. This product is a product with high environmental risk.
Special dryer for sodium thiocyanate Working principle:
This machine is a novel horizontal intermittent vacuum drying equipment. The wet material is evaporated by conduction. The scraper stirrer continuously removes the material on the hot surface and forms a circulating flow in the container. After the water evaporates, it is extracted by the vacuum pump. .
Special dryer for sodium thiocyanate Features:
◎This machine adopts large-area interlayer heating method with large heat transfer surface and high thermal efficiency.
◎The machine is set to stir, so that the material forms a continuous circulation state in the cylinder, which further improves the uniformity of heat of the material.
◎The machine is set to stir, so that the slurry, paste and paste materials can be dried smoothly.
Special dryer for sodium thiocyanate
◎The following materials are dried in the pharmaceutical, food, chemical and other industries:
◎Applicable to slurry, paste and powder materials;
◎ heat sensitive materials requiring low temperature drying;
◎Easy to oxidize, explosive, strong irritant, highly toxic materials;
◎Requires the recovery of organic solvent materials.
Functional advantages of vacuum kneading dryers when drying materials:
1. Feed pellets or powder can be delivered to the container by vacuum delivery or manual.
2. As the container rotates continuously, the material undergoes complex impact movements in the container to achieve uniform mixing.
3. Energy saving, convenient operation, low labor intensity and high work efficiency.
4, automatic constant temperature control, can be adjusted to 20.
5. Compared with other dryers, its thermal efficiency will be doubled.
6. Indirect heating to keep raw materials free from contamination.
7, vacuum dryer features: washing and maintenance is convenient.
Vacuum dryer safe operation method:
1. Connect the intake pipe behind the vacuum kneading dryer with a vacuum rubber tube and a vacuum pump to turn on the vacuum pump power supply.
2. The items to be dried are placed in the machine, the door is closed, the vent valve is closed, the vacuum valve is opened, and then the vacuum pump power is turned on to start pumping, so that the machine reaches a vacuum of -0.1Mpa, and the vacuum valve is closed. Turn off the vacuum pump power switch.
3. After the setting is completed, the data will be saved for a long time. The -type vacuum dryer enters the warming state, and the heating indicator (green light) lights up. When the temperature is close to the set temperature, the traffic lights are staggered and repeated several times, and the control enters a constant temperature state.
4. Plug in the power supply, the temperature controller displays the number, and set the temperature and heating mode (when the temperature rises, the full power heating gear can be hit to 1, and the constant temperature half power heating gear hits 2).
5. After the drying is finished, first turn off the power, rotate the bleed valve, release the vacuum inside the machine, and take out the items.
