Fine Chemicals Conical-Cylindrical Vacuum Dryer Introduction


In the post-treatment process of the fine chemical production process, there are often unit operations such as filtration, washing, and drying. These unit operations are usually operated separately by unit equipment such as centrifugal filters, washing tanks and dryers. The equipment is transported through pipelines or other methods. materials. A system of large equipment, long flow, low efficiency, and difficult-to-adjust production process with multiple unit equipments connected together. For suspensions with high solids content, solids tend to stick to the walls and block the pipelines, making it difficult to perform normal production. Open-type production is easy to deal with the clogging problem, but it is difficult to meet the regulatory requirements for medicine, food, biological products, etc., and there are hidden safety hazards for flammable, explosive, toxic or highly toxic materials.

In order to overcome the problems and deficiencies in the above-mentioned unit equipment combination, and at the same time to meet the chemical industry's transition to high quality, high added value, multiple varieties, and small batches, Wuxi Shuangrui Machinery Co., Ltd. has carried out a lot of design and research and development work, and finally successfully developed Developed a multifunctional cylindrical-cone reaction filter dryer that integrates filtration, washing and drying, and successfully applied for a patent (Patent No.: ZL201721560677.6.), which achieved a great improvement in the technical performance of the equipment, from structural design to application. Follow the corresponding regulatory requirements of the pharmaceutical industry. The equipment has the three main functions of filtration, washing and drying, and also has multiple functions such as reaction, extraction, crystallization, concentration, evaporation, mixing, and crushing. It is a high-tech equipment and has the following advantages:


Fine Chemicals Conical-Cylindrical Vacuum Dryer1 


1. Closed operation, multiple processes are completed in the same equipment, reducing the impact of dust and microorganisms on the quality of materials, reducing the loss of valuable materials, thereby improving product quality and output.

2. Reduce the material transportation links, especially the transportation of filter cakes, shorten the production cycle and increase the production capacity.

3. The filtration and washing operations can be carried out under vacuum or pressure, and the process operation is flexible and easy to control.

4. For the disposal of flammable, explosive, toxic or highly toxic dangerous goods, reduce environmental pollution, improve the working environment, and operate safely.

5. Short process, reduce equipment, reduce plant space and reduce project investment.


Fine Chemicals Conical-Cylindrical Vacuum Dryer working principle


Fine Chemicals Conical-Cylindrical Vacuum Dryer

 

The new filter washing and drying machine has a cylindrical cone structure. A heating jacket is set on the cylinder and the lower cone to heat or cool the material. A hollow shaft and a hollow shaft with variable angle and lead are arranged inside the multifunctional machine. The spiral stirring device stirs, stirs and lifts the material, and pushes the material out when it is discharged. A conical filter device with a more complicated structure is arranged in the lower cone, and a specially designed quick-opening discharge device without dead angle or a pneumatic discharge ball valve without dead angle is arranged at the bottom of the equipment.


In the reaction stage, the reaction material is added from the top. The unique stirring structure can make the material get a very uniform stirring in the machine, and it is heated or cooled through the barrel jacket, cone jacket, hollow shaft and hollow spiral blade at the same time. Make the material fully react in the machine. In the filtering stage, the machine can make the material in the machine filter dry by pressurizing or vacuuming, and add washing liquid, so that the material can be automatically repulped and washed in the machine for many times, and then pressed dry after reaching the washing requirements. In the drying stage, the barrel jacket, cone jacket, hollow shaft, and hollow spiral belt heat the materials at the same time and draw a vacuum on the top, and vacuum-sealed the materials for low-temperature drying. After drying, the materials are automatically sealed and discharged.

1. Stirring reaction: This machine has a barrel-cone structure, and can be used to heat or cool materials in the machine for constant temperature and timing reaction;

2. Pressure filtration or vacuum filtration: After the reaction, the filtrate is filtered through pressure filtration or vacuum suction. In the filtration stage, due to the good adhesion of the ribbon and the filter medium, the material can be placed in the thin layer of the filter cake. Filter under conditions, with high filtering efficiency;

3. It can be washed and filtered multiple times: After filtering and drying the material, you can add the washing liquid, and perform multiple automatic reaction and mixing with the material in the machine before washing. After the washing and filtering meet the washing requirements, it can be filtered and dried.

4. Vacuum drying and discharging: After the material is filtered and dried, the barrel jacket, hollow shaft and spiral belt are heated at the same time in the drying section, and the material is vacuum-sealed and dried at low temperature by vacuum at the top. After drying, the material is automatically sealed Discharge.


Fine Chemicals Conical-Cylindrical Vacuum Dryer performance characteristics

1. One machine with multiple functions, can complete various operations such as reaction, extraction, filtration, repeated filtration, washing, and drying in one machine, and directly obtain the finished product.

2. Airtight operation, especially suitable for handling flammable, explosive, toxic or highly toxic dangerous products and fresh food, biological products and medicines that are not allowed to be contaminated.

3. Cylinder jacket, cone jacket, hollow shaft and hollow spiral belt can heat or cool materials at the same time, with high thermal efficiency and low energy consumption.

4. The special agitating screw design can make the materials very uniformly agitated in the various stages of reaction, filtration, washing and drying, so that the working efficiency of the whole machine is very high.

5. In the filtering stage, due to the good adhesion and scraping effect of the spiral belt and the filter medium, the material can be filtered under the condition of a thin layer of filter cake, and the filtering efficiency is high.

6. Simplify and shorten the process flow, occupy a small area, and greatly save plant and equipment investment.

7. Convenient operation, low labor intensity, and good quality of processed products.
