Research and development and industrial application of cylinder-cone reaction, filtration and drying integrated machine

2023/03/30

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 a cylinder-cone reaction filtration and drying integrated machine, the invention patent number: ZL201721560677.6. It has achieved a major breakthrough in chemical equipment technology.

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


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 cylinder-cone reaction, filtration and drying integrated machine is used in solid material recovery, solvent recovery, raw material drug filtration, washing, drying and other occasions in the biopharmaceutical process. The operation procedure is reduced, the production process is accelerated, the production cost is saved, and the purity and quality of the medicine are improved. Filtration, washing and drying of printing and dyeing raw materials and filtering, washing and drying of pesticide raw materials.

Vitamins, penicillin, toluene, methanol, ethanol, ether, etc. need to be washed and recycled. Chemicals, polymers and resin products for agricultural extraction. Plant extracts are stored and filtered to reduce operating procedures and speed up the production process.




In the fine chemical industry such as nickel production, copper foil production, circuit board production, recovery of various precious metal catalysts, and the occasions that require washing and recovery such as bisglyphosate and glyphosate. The cylinder-cone reaction, filtration and drying multifunctional machine protects metal processing tools and improves the qualified rate of products. As well as the filtration of raw materials such as resins, filtration and recovery of solvents.

Recover precious metals, protect metal processing tools, and improve the precision level of metal processing. Remove the agglomerated impurities after the mixing reaction and improve product quality. Remove coagulation of gel paint, improve heat exchange efficiency, etc.



In sugar production, the cylinder-cone reaction, filtration and drying integrated machine intercepts carbon ink and filter aid in sugar making, reducing operating costs. Applied to zeolite production, titanium dioxide production, melamine production, chlor-alkali industry production, epoxy resin production, etc., it can significantly reduce operating costs, protect key equipment, remove large particles, and improve the operation efficiency of magic. Improve the gloss and purity of epoxy resin, and make the coating film uniform.

Thereby improving product quality.

In the decolorization and decarburization of bisglyphosate and glyphosate, the cylinder-cone reaction, filtration and drying machine reduces the operating procedures and speeds up the production process. Applied to the filtration of circulating water in the glass and ceramic industries, it can greatly reduce operating costs and energy consumption, and avoid fluctuations in product quality.

In activated carbon filtration, decolorization and effective adsorption of toxic and harmful substances are realized, and the recovered solvent is filtered, thereby greatly improving the quality of the product, with unparalleled advantages. During the recovery of polysilicon powder and the filtration of waste acid (hydrofluoric acid and nitric acid), the normal operation of key equipment is protected, and the cost of operation and treatment is reduced.

The cylinder-cone reaction, filtration and drying integrated machine can realize filtration and recovery of solvents, screening of large particles, improvement of product quality and efficiency of heat exchange in flue gas desulfurization filtration, glass erosion filtration, and various fine chemical processes.

Separation of decolorization and activated carbon from edible oil and security filtration before canning can protect the normal operation of key equipment, reduce production and labor costs, and improve the quality of finished products, such as product gloss, purity, and taste.

The cylinder-cone reaction, filtration and drying integrated machine is used in oilfield water injection, process circulating water, cooling water filtration, lubricating oil, aviation fuel and other oil products, recovery of catalysts, filtration of catalytic oil slurry, interception of carbon ink and filter aids, separation from extraction Separated polymers reduce operating costs and energy consumption and stabilize product quality. In wastewater treatment applications, sand, algae and other silt deposits in raw water are filtered, iron and steel industry, air-conditioning systems, compressor circulating cooling water, chilled water filtration, scale or calcification in water pipes are removed, filtration, and pre-filtration of membrane purification liquid Intercept ion exchange resin, remove polluting particles, realize energy saving and emission reduction, and reduce waste water treatment cost.
