Description

Technical Field

[0001] This invention relates to the field of chemical production technology, specifically to a drying apparatus for producing sodium dodecyl sulfate. Background Technology

[0002] Sodium dodecyl sulfate (SLS) is an organic compound, a white or pale yellow powder, readily soluble in water, insensitive to alkalis and hard water. It possesses detergency, emulsification, and excellent foaming power. It is a slightly toxic anionic surfactant with a biodegradability greater than 90%, decomposing at around 200 degrees Celsius. SLS exhibits good emulsifying, foaming, and water-soluble properties, is biodegradable, alkali-resistant, hard water-resistant, and stable in aqueous solutions over a wide pH range. It is also easy to synthesize and inexpensive. Therefore, it has been widely used in cosmetics, detergents, textiles, papermaking, lubricants, pharmaceuticals, building materials, chemicals, and oil extraction industries. Furthermore, it can be applied to fundamental research on the properties of positive and negative ionic surfactant complexes, micellar catalysis, and ordered molecular combinations.

[0003] Because sodium dodecyl sulfate has a certain degree of water absorption, it is easily affected by moisture before it is sealed in packaging. Moisturized sodium dodecyl sulfate is prone to clumping or deterioration after sealing. In order to extend the shelf life of sodium dodecyl sulfate and ensure product quality, it needs to be dried before packaging. Summary of the Invention

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The drying device for producing sodium dodecyl sulfate, through the setting of a packaging support mechanism, a material guiding and crushing mechanism, a hydrothermal drying mechanism, a closed feeding mechanism, and a moisture and odor emission mechanism, can generate a temperature continuously below 100 degrees Celsius through the hydrothermal drying mechanism, and heat the sodium dodecyl sulfate material through the conduction of the material guiding and crushing mechanism. This ensures that the sodium dodecyl sulfate is not decomposed by high temperature while ensuring its drying, and further guarantees the shelf life of the sodium dodecyl sulfate after sealing and packaging.

[0017] 2. This drying device for producing sodium dodecyl sulfate, through its frame, side plates, enclosing bottom plate, top plate, feed inlet, dust filter blocks, protective mesh, discharge hopper, isolation suspension cloth, and counterweights, provides support and load-bearing capacity while forming a certain degree of enclosure and sealing of the device's interior through the side plates, enclosing bottom plate, and top plate. Most of the external cold drying gas can only enter the interior through the dust filter blocks to replenish it. In conjunction with the moisture and odor emission mechanism, it ensures that the moisture during dehumidification is quickly replaced while preventing the easy release of large amounts of irritating gases. Furthermore, the isolation suspension cloth ensures smooth material discharge while also creating a certain degree of isolation between the inside and outside of the device.

[0018] 3. The drying device for producing sodium dodecyl sulfate is equipped with a drive shaft, drive roller, heat conduction belt, drive motor, isolation plate, sealing strip, guide block, support shaft, first transmission shaft, second transmission shaft, support roller, pressure belt, anti-slip strip, active transmission wheel, driven transmission wheel, cleaning roller, cleaning brush and belt, so as to ensure that the material can move forward smoothly and at a uniform speed, and ensure that the material can pass smoothly under the pressure frame without clogging through the cooperation of the heat conduction belt and the pressure belt.

[0019] 4. The drying device for producing sodium dodecyl sulfate, through the setting of support frame, pressure frame, lower pressure spring, sliding shaft and guide groove, can ensure that the lumps in the material below the pressure frame are crushed by the extrusion of the pressure frame, and ensure that the material is heated and dehumidified evenly.

[0020] 5. The drying device for producing sodium dodecyl sulfate, through the configuration of a first supporting insulated hot water tank shell, a second supporting insulated hot water tank shell, a hot water conducting tank shell, an electric heating rod, an upper conduit, a pressure-reducing tank, an observation window, a first solenoid valve, a drain tee, an exhaust pipe, a one-way valve, a water inlet connector, a drain connector, and a second solenoid valve, can indirectly dry the material through the heat generated by hot water, ensuring that the heating temperature is below 100 degrees Celsius under normal temperature and pressure, thus preventing the material from reaching its thermal decomposition temperature during drying.

[0021] 6. The drying device for producing sodium dodecyl sulfate, through the installation cover, exhaust fan, overlapping frame, dust-blocking cloth, side frame, air washing box, air inlet, exhaust connector, lower edge pipe, connecting cover, air guide hose and hose connector, can conduct and coarsely purify a large amount of irritating and humid air inside the device to the outside, avoiding the gradual increase of air humidity inside the device from affecting drying, while reducing the outflow of irritating gas.

Through the mounting cover 501, exhaust fan 502, overlapping frame 503, dust-blocking cloth 504, side frame 505, air washing box 506, air inlet 507, exhaust connector 508, lower edge pipe 509, connecting cover 510, duct hose 511, and hose connector 512, a large amount of irritating and humid air inside the device can be conducted outward and coarsely purified, avoiding the gradual increase of air humidity inside the device from affecting drying, while reducing the outward flow of irritating gas.

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

[0047] Working principle: First, connect the exhaust connector 508 to the external exhaust gas pipe, the water inlet connector 312 to the external water inlet pipe, and the drain connector 313 to the external drain pipe. Then, unscrew the connection between the hose connector 512 and the air inlet 507 to fill the air washing tank 506 with water. After filling to a certain water level, reconnect the hose connector 512 to the air inlet 507. Then, close the second solenoid valve 314, open the first solenoid valve 308, and open the valve of the external water inlet pipe to fill the first supporting insulated water tank shell 301, the second supporting insulated water tank shell 302, and the hot water conducting water tank shell 303 with water. Water is added until the water level is greater than the height of the second support insulated water tank shell 302. Then, the air inside the first support insulated water tank shell 301, the second support insulated water tank shell 302, and the hot water conduction tank shell 303 is vented. 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 tank 306. Then, the electric heating rod 304 is energized. After the electric heating rod 304 is energized, it continuously heats the water inside the first support insulated water tank shell 301, the second support insulated water tank shell 302, and the hot water conduction tank shell 303. The heat is conducted to the heat conduction tape 203 through the hot water conduction tank shell 303, so that the heat conduction tape 203 is heated.

[0048] Simultaneously, the exhaust fan 502 is activated, and the exhaust fan 502 continuously pumps the air inside the device to the external exhaust gas pipeline. After passing through the dust-blocking cloth 504, the airflow enters the air washing box 506 in sequence through the mounting cover 501, exhaust fan 502, connecting cover 510, air guide hose 511, hose connector 512 and air inlet 507. Then, after entering water through the lower edge pipe 509, it is discharged into the external exhaust gas pipeline through the exhaust connector 508.

[0049] Simultaneously, the drive motor 204 is started, which drives the drive shaft 201 to rotate. When the drive shaft 201 rotates, it drives the drive roller 202 to rotate. When the drive roller 202 rotates, it drives the heat conduction tape 203 to move. When the heat conduction tape 203 moves, it moves the pressure belt 212 synchronously through the anti-slip strip 213. When the pressure belt 212 moves, it drives the first transmission shaft 209 to rotate through the support 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 cleaning brush 217 rotate.

[0050] Then, open the flip cover 402 to put sodium dodecyl sulfate material into the feed box 401. After closing the flip cover 402 and preheating for a period of time, twist the actuating block 408 to open the flip plate 404 through the rotating shaft 403, so that the top of the feed port 105 is open. The material falls through the feed port 105 onto the surface of the guide plate 406, and then slides along the guide plate 406 to the surface of the heat conduction tape 203. When the heat conduction tape 203 moves, it drives the material on the surface forward. When the material moves forward, the material on both sides is pushed inward when it passes the guide block 207, and then gradually reaches the bottom of the pressure belt 212. The material that reaches the bottom of the pressure belt 212 is pushed to the bottom of the support frame 219 by the pressure belt 212 and the heat conduction tape 203, and then is supported. The support frame 219 compresses the clumps formed by hand-compression, breaking them down into powder. The powder continues to move forward with the heat conduction tape 203. As the powder moves forward with the heat conduction tape 203, the heat conduction tape 203 conducts heat to the powder above, causing the powder to heat up and evaporate its internal moisture. The powder continues to fall into the discharge hopper 108 after reaching the end of the heat conduction tape 203, and is then discharged from the discharge hopper 108, thus achieving material drying. At the same time, the evaporated moisture mixes with the gas inside the device and is pumped into the air washing box 506 by the exhaust fan 502 for cleaning before being discharged into the external exhaust gas pipe. In order to maintain air pressure balance, relatively dry external air passes through the dust filter block 106 and enters the device to replenish it.

[0051] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
