New process of paracetamol refining and purification, filtering, washing and drying three-in-one machine


Paracetamol, trade names include Baifuning, Biliton, Tylenol, and acetaminophen. The international non-proprietary drug name of this product is Paracetamol. It is the most commonly used non-anti-inflammatory antipyretic and analgesic drug. Its antipyretic effect is similar to that of aspirin, but its analgesic effect is weak. It has no anti-inflammatory and anti-rheumatic effects. It is the best variety among acetanilide drugs.

It is especially suitable for patients who cannot use carboxylic acid drugs. For colds, toothache and other diseases. Acetaminophen is also an intermediate in organic synthesis, a stabilizer for hydrogen peroxide, and a photographic chemical.

The new process of paracetamol refining and purification, the working principle of the three-in-one filter, washing and drying machine

The machine is of barrel-cone structure, and there are heating jackets on the cylinder body and the lower cone, which can heat or cool the materials. The multi-function machine is equipped with a hollow shaft and a variable-angle variable-lead hollow spiral stirring device. Stirring, stirring and lifting the material, pushing out the material when discharging. A conical filtering device with a relatively complex structure is installed in the lower cone, and a specially designed non-dead angle quick-opening discharge device or a non-dead angle pneumatic discharge ball valve is installed at the bottom of the equipment.

In the reaction stage, the reaction materials are added from the top, and the unique stirring structure can make the materials be stirred evenly in the machine, and the materials are heated or cooled simultaneously through the cylinder jacket, cone jacket, hollow shaft, and hollow spiral blade. Make the material fully react in the machine.

In the filtration stage, the machine can filter and dry the material in the machine by pressurizing or vacuuming, and add washing liquid, so that the material can be automatically repulped and washed several times in the machine, and then pressed dry after meeting the washing requirements. In the drying stage, the cylinder jacket, cone jacket, hollow shaft, and hollow ribbon heat the material at the same time and vacuumize the top, vacuum-tight and low-temperature drying of the material, and automatically seal and discharge the material after drying.

The new process of refining and purifying paracetamol The product advantages of the three-in-one all-in-one machine for filtering, washing and drying:

1. Closed system: The three-in-one filter, washing and drying system is a fully closed system. Production and operation in the closed system can avoid air pollution from toxic substances, and at the same time reduce the occurrence of poisoning accidents by operators.

2. Recycling: materials and solvents are almost completely recovered, avoiding waste caused by material omission and solvent volatilization, which has great economic benefits.
3. Multifunctional integrated operation: filtering, washing and drying are completed in the same equipment. The vessel walls are equipped with heating jackets to allow drying.

4. Continuous operation: Filtration and drying are carried out in a continuous system, no need to deal with wet filter cake. The dried products can be mechanically transferred to the weighing and packaging sections.
5. Saving manpower: a non-technical person who has undergone simple training can complete the operation.

Opening, closing, automatic feeding and automatic discharging do not require technical personnel to monitor.
6. Thorough cleaning: The filter, washing and drying three-in-one has the functions of automatic spraying and stirring, and the filter cake can be fully cleaned, thereby reducing the amount of sewage and reducing the cost of wastewater treatment.
7. Clean production: The multifunctional filter drying system is equipped with a dust collector to collect the dust produced after drying, which can meet the requirements of clean production.

1. Stirring reaction: This machine is a barrel-cone structure, which can heat or cool the material in the machine for constant temperature and timing reaction;
2. Pressure filtration or vacuum filtration: After the reaction is completed, filter the filtrate through pressure filtration or vacuum suction filtration. In the filtration stage, due to the good adhesion between the ribbon and the filter medium and the scraping effect, the material can be kept in the thin layer of filter cake Filtration under the best conditions, high filtration efficiency;
3. Can be washed and filtered multiple times: After filtering and drying the material, you can add washing liquid, and perform multiple automatic reactions and mixing with the material in the machine before washing, and then filter and dry after washing and filtering meet the washing requirements.
4. Vacuum drying and discharging: After the material is filtered and dried, the material is heated at the same time in the jacket of the drying section, the hollow shaft and the spiral belt, and the vacuum is vacuumed at the top to dry the material in vacuum and low temperature, and it is automatically sealed after drying. Discharge.
