Description

Technical Field

[0001] The invention relates to the technical field of chemical production, in particular to a drying device for producing sodium lauryl sulfate. Background Art

[0002] Sodium dodecyl sulfate is an organic compound, a white or light yellow powder, easily soluble in water, insensitive to alkali and hard water, with cleaning, emulsification and excellent foaming power. It is an anionic surfactant that is slightly toxic to the human body, with a biodegradability of more than 90%, and it decomposes at about 200 degrees Celsius. Sodium dodecyl sulfate has good emulsification, foaming, water solubility, biodegradability, alkali resistance, hard water resistance, stability in aqueous solutions with a wide pH value, easy synthesis, and low price. It has been widely used in cosmetics, detergents, textiles, papermaking, lubrication, as well as pharmaceuticals, building materials, chemicals, oil production and other industries. It can also be used in basic research on the properties of positive and negative ion surfactant complex systems, micelle catalysis, and molecular ordered assemblies.

The top of the device is fixedly connected to the inside of the air inlet interface 507, the connecting cover 510 is fixedly connected to the upper surface of the mounting cover 501, the air guide hose 511 is fixedly connected to the top of the connecting cover 510, and the hose connector 512 is fixedly installed at one end of the air guide hose 511. Through the mounting cover 501, the exhaust fan 502, the lap frame 503, the powder blocking cloth 504, the side frame 505, the air washing box 506, the air inlet interface 507, the exhaust connector 508, the lower pipe 509, the connecting cover 510, the air guide hose 511 and the hose connector 512, a large amount of irritating and humid air inside the device can be conducted outward and roughly purified, thereby avoiding the gradual increase of the air humidity inside the device and affecting the drying, and reducing the outflow of irritating gases.

[0046] Among them; the side frame 505 is slidably connected to the air washing box 506, the air inlet interface 507 is threadedly connected to the hose connector 512, and a sealing ring is provided inside the hose connector 512, so that the air washing box 506 can be disassembled and replaced at any time.

[0047] Working principle: first, connect the exhaust joint 508 to the external exhaust pipe, connect the water inlet joint 312 to the external water inlet pipe, connect the drain joint 313 to the external drain pipe, then twist the connection between the hose joint 512 and the air inlet interface 507, and inject water into the washing box 506. After a certain water level is injected, connect the connection between the hose joint 512 and the air inlet interface 507 again, then close the second solenoid valve 314, open the first solenoid valve 308, open the valve of the external water inlet pipe, and inject water into the first supporting insulated water tank shell 301, the second supporting insulated water tank shell 302 and the heat conducting water tank shell 303. Water, until the water level is greater than the height of the second supporting insulated water tank shell 302, the air inside the first supporting insulated water tank shell 301, the second supporting insulated water tank shell 302 and the hot water tank shell 303 is emptied, and the valve of the external water inlet pipe and the first solenoid valve 308 are closed. At this time, a large space is reserved inside the pressure relief tank 306, and then the electric heating rod 304 is energized. After the electric heating rod 304 is energized, the water inside the first supporting insulated water tank shell 301, the second supporting insulated water tank shell 302 and the hot water tank shell 303 is continuously heated, and the heat is transferred to the heat conductive belt 203 through the hot water conductive tank shell 303, so that the heat conductive belt 203 is heated;

[0048] At the same time, the exhaust fan 502 is started, and the exhaust fan 502 continuously pumps the air inside the device to the external exhaust pipe. After passing through the powder blocking cloth 504, the airflow enters the air washing box 506 from the installation cover 501, the exhaust fan 502, the connecting cover 510, the air guide hose 511, the hose connector 512 and the air inlet interface 507 in sequence, and then enters the water through the lower pipe 509 and is discharged from the exhaust connector 508 into the external exhaust pipe;

[0049] At the same time, the driving motor 204 is started, and the driving motor 204 drives the driving shaft 201 to rotate. When the driving shaft 201 rotates, it drives the driving roller 202 to rotate. When the driving roller 202 rotates, it drives the heat-conducting belt 203 to move. When the heat-conducting belt 203 moves, it drives the pressing belt 212 to move synchronously through the anti-slip strip 213. When the pressing belt 212 moves, it drives the first transmission shaft 209 to rotate through the supporting roller 211. The first transmission shaft 209 drives the second transmission shaft 210 to rotate through the active transmission wheel 214, the driven transmission wheel 215 and the belt 218, so that the cleaning roller 216 and the powder cleaning brush 217 rotate;

[0050] Then, open the flap 402 and put the sodium dodecyl sulfate material into the feed box 401. After closing the flap 402 and preheating for a period of time, twist the toggle block 408, and open the flap 404 through the rotating shaft 403, so that the top of the feed port 105 is open, and the material falls onto the surface of the guide plate 406 through the feed port 105, and then slides along the guide plate 406 to the surface of the heat conducting belt 203. When the heat conducting belt 203 moves, it drives the material on the surface forward. When the material moves forward, the materials on both sides are pushed inward when passing through the guide block 207, and then gradually reach the bottom of the pressing belt 212. The materials that reach the bottom of the pressing belt 212 are pushed to the bottom of the support frame 219 along with the pressing belt 212 and the heat conducting belt 203, and then are supported. The support frame 219 is squeezed to crush the hand-extruded clumps into powder again, and then the powder continues to move forward along the conductive belt 203. While the powder moves forward along the conductive belt 203, the conductive belt 203 transfers heat to the powder above, so that the powder is heated. The heated powder evaporates the internal moisture until the powder reaches the end of the conductive belt 203 and falls into the discharge hopper 108, and is then discharged from the discharge hopper 108, thereby achieving the drying of the material. At the same time, after the moisture evaporates, it mixes with the gas inside the device and is pumped into the washing box 506 by the exhaust fan 502 for cleaning, and then discharged into the external exhaust pipe. In order to maintain the air pressure balance, the relatively dry air outside passes through the dust filter block 106 and enters the device for replenishment.
