Cylindrical and conical reaction filtration washing and drying machine

At present, in China's chemical industry, equipment such as centrifuges, plate and frame filters, and vacuum filters are used to filter and separate materials. Most of these devices have single functions, high labor intensity, and significant material loss during operation. What is more concerning is that these devices are generally operated in an open manner, which can easily cause environmental pollution and endanger the health of operators. There are also some problems with the use of drying equipment. The most prominent ones are the incomplete recovery of solvents and the insufficiency of dust collection devices. Some production enterprises adopt open-air drying methods, which are not only detrimental to the economy but also to the environment and affect product quality. These issues must be improved as soon as possible.

过滤洗涤干燥机(业内俗称“三合一”)能实现物料的过滤、洗涤、干燥、灭菌、卸料等连续工艺过程，其操作方式属于分批式操作(间歇操作)，广泛应用于制药、食品、农药、化工等领域，可以避免物料在转移过程中可能引起的物料损失、污染及环境污染。
现有三合一的结构是平板式，但是在长期生产使用中发现一些缺陷，例如：圆形平底过滤面积小；侧面出料，导致出料不彻底；干燥效果不理想，干燥过程中的物料翻动小，换热效率低，干燥效果受限制等。

  为克服上述机组设备组合存在的问题和不足，满足化工向高品质、高附加价值、多品种、小批量的转变，无锡双瑞进行了大量的设计研究开发，终于开发出集过滤、清洗、干燥为一体的多功能锥形结晶过滤洗涤干燥一体机(专 利号：ZL 201721560677.6)，实现了装备技术性能的大幅改善，从结构设计应用该设备具有过滤、洗涤、干燥三个主要功能，还兼有反应、萃取、结晶、浓缩、蒸发、混合、破碎等多项功能，而且在多家客户企业中应用。

The working principle of the cylindrical and conical reaction filtration washing and drying machine

The new type of filtration, washing and drying machine adopts a cylindrical and conical structure. Heating jackets are set on the cylindrical body and the lower conical body, which can heat or cool the materials. Inside the multi-functional machine, there are hollow shafts and variable-angle and variable-lead hollow spiral stirring devices for stirring and lifting the materials, and the materials are pushed out when discharging. A relatively complex conical filtering device is set in the lower cone. At the bottom of the equipment, there is a specially designed quick discharge device without dead corners or a pneumatic discharge ball valve without dead corners.

During the reaction stage, the reaction materials are added from the top. The unique stirring structure enables the materials to be evenly stirred inside the machine. Through the simultaneous heating or cooling of the cylinder jacket, conical jacket, hollow shaft and hollow spiral blades, the materials can be fully reacted inside the machine. During the filtration stage, this machine can make the material dry through pressure or vacuum filtration inside the machine, and add washing liquid to make the material undergo multiple automatic re-slurry washing inside the machine. After meeting the washing requirements, it can be pressed dry again. During the drying stage, the cylinder jacket, conical jacket, hollow shaft and hollow screw ribbon simultaneously heat the material and create a vacuum at the top to conduct vacuum sealed low-temperature drying of the material. After drying, the material is automatically sealed and discharged.

The process flow of the cylindrical and conical reaction filtration washing and drying machine

(1) Stirring reaction: This machine adopts a cylindrical and conical structure, allowing for constant-temperature and timed reactions of heating or cooling materials within the machine.

(2) Pressure filtration or vacuum filtration: After the reaction is completed, the filtrate is filtered through pressure filtration or vacuum suction filtration. During the filtration stage, due to the good adhesion and scraping effect between the helical ribbon and the filter medium, the material can be filtered under the condition of a thin filter cake, with high filtration efficiency.

(3) Multiple washing and filtration are possible: After the material is filtered and dried, washing liquid can be added and it can undergo multiple automatic reactions and mixes with the material inside the machine before washing. After the washing and filtration meet the washing requirements, it can be filtered and dried again.

(4) Vacuum drying and discharging: After the material is filtered and dried, it is heated simultaneously in the jacket of the drying section cylinder, the hollow shaft and the screw ribbon. A vacuum is then applied at the top for vacuum low-temperature sealed drying of the material. The dried material is automatically sealed and discharged.

Performance features of the cylindrical and conical reaction filtration washing and drying machine

(1) Multi-functional in one machine, it can complete various operations such as reaction, extraction, filtration, repeated filtration and washing, and drying within one machine, and directly obtain the finished product.

(2) Closed operation is particularly suitable for handling flammable, explosive, toxic or highly toxic dangerous products, as well as fresh and delicious foods, biological products and medicines that are not allowed to be contaminated.

(3) The cylinder jacket, conical jacket, hollow shaft and hollow screw ribbon simultaneously heat or cool the material, featuring high thermal efficiency and low energy consumption.

(4) The special stirring screw design enables uniform stirring of the materials during each stage of reaction, filtration, washing and drying, thus making the overall working efficiency of the machine very high.

(5) During the filtration stage, due to the good adhesion and scraping effect between the helical ribbon and the filter medium, the material can be filtered under the condition of a thin layer of filter cake, resulting in high filtration efficiency.

(6) Simplify and shorten the process flow, occupy a small area, and greatly save investment in factory buildings and equipment.

(7) It is easy to operate, has low labor intensity and the quality of the processed products is good.
