Multifunctional cylinder cone filter washing and drying machine equipment overview

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 independently by unit equipment such as centrifugal filters, washing tanks, and dryers. The equipment is transported through pipelines or other methods. materials. Multiple units of equipment are connected into a system of large devices, long processes, low efficiency, and difficult to adjust the production process. For suspensions with high solid content, solids often stick to the wall and block the pipeline, making it difficult to carry out normal production. Open production is easy to deal with clogging problems, but it is difficult to meet the regulatory requirements for medicine, food, biological products, etc., and there are still potential safety hazards for flammable, explosive, toxic or highly toxic materials.

In order to overcome the problems and deficiencies in the combination of the above-mentioned unit equipment, and at the same time meet the transformation of the chemical industry to high-quality, high-value-added, multi-variety, and small-batch, Wuxi ZhangHua Machinery Co., Ltd. has carried out a lot of design and development work, and finally successfully developed it. The multi-functional cylinder-cone reaction filter dryer integrating filtration, washing and drying has successfully applied for a patent (patent number: ZL201721560677.6.), which has achieved a major improvement in the technical performance of the equipment, from structural design to application. Comply with the corresponding regulatory requirements of the fine chemical industry. The equipment has three main functions of filtering, washing and drying, and also has many functions such as reaction, extraction, crystallization, concentration, evaporation, mixing and crushing, etc. It belongs to high-tech equipment

Multifunctional cylinder cone filter washing and drying machine working principle

The new filter washing and drying machine has a barrel-cone structure. There are heating jackets on the cylinder body and the lower cone body to heat or cool the materials. There are hollow shafts and variable-angle variable-lead hollow shafts inside the multi-function machine. The spiral stirring device stirs, stirs and lifts the material, and pushes 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.

Multifunctional cylinder cone filter washing and drying machine process flow

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.

Multifunctional cylinder cone filter washing and drying machine performance characteristics

1. One machine is multi-purpose, and can complete various operations such as reaction, extraction, filtration, repeated filtration, washing, and drying in one machine, and the finished product can be obtained directly.

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

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

4. The special stirring screw design can make the material be stirred evenly in each stage of reaction, filtration, washing and drying, so that the working efficiency of the whole machine is very high.

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

6. Simplify and shorten the technological process, occupy a small area, and greatly save the investment in workshops and equipment.

7. The operation is convenient, the labor intensity is low, and the processed products are of good quality.
