The new filter, washing and drying three-in-one has achieved a major breakthrough in chemical equipment technology


As we all know, reaction, filtration, and drying are three very important unit operations in the chemical, pharmaceutical, and food industries. Generally, there are three unit equipments: reactor, filter, and dryer. These three units of equipment have their own supporting devices. Due to the large area and high cost, the handling or transportation of materials between units is troublesome, not only labor-intensive, but also easy to cause loss and waste of materials. Inflammable, explosive, toxic or highly toxic materials or biological products, drugs, food, etc. that are not allowed to be polluted require airtight operation. At this time, it is more difficult to transport materials between the three devices of reaction, filtration, and drying. Sometimes This often causes the whole set of equipment to be unable to fully operate normally or the labor intensity is high, the production cycle is long, the energy consumption is large, and the efficiency is low, which affects the product quality.

It is based on the above reasons that Wuxi ZhangHua Machinery Co., Ltd. has carried out a lot of design and development work, and finally successfully developed the SR-tubular cone reaction filter drying multifunctional machine, the invention patent number: ZL2017 2 1560677.6. Realized the breakthrough of chemical equipment technology major breakthrough.

The invention of this machine has had a major impact on the field of chemical equipment technology in China and the world.

The working principle of the new three-in-one equipment for filtering, washing and drying

The new cylinder-cone filtering, washing and drying three-in-one equipment is a cylinder-cone structure. There are heating jackets on the cylinder body and the lower cone body, which can heat or cool the materials. Angle-variable-lead hollow 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. The unique stirring structure can make the materials get the most uniform mixing 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 three-in-one process of cylinder cone filtration, washing and drying

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.

The performance characteristics of the new cylinder-cone filter, washing and drying three-in-one

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.
