Industry case
Vacuum drying is to dry the material to be dried by heating under vacuum conditions. It uses a vacuum pump for pumping and dehumidifying, so that the studio is in a vacuum state, the drying rate of the material is greatly accelerated, and energy is also saved. Note: If a condenser is used, the solvent in the material can be recovered through the condenser; if SK series water ring vacuum pump or ZSWJ series hydraulic jet vacuum pump unit is used, the condenser is not needed, saving energy investment.
The special double-cone rotary vacuum drying host for battery materials is a double-cone tank body. Under the vacuum state inside the tank, steam or heat transfer oil can be introduced into the jacket to heat the inner container. The heat is transferred to the wet material through the inner container, so that the water in the wet material is gasified. The low-speed motor drives the tank body to rotate. The material keeps going up and down, turning inside and outside, and replacing the heating surface. At the same time, the water vapor is continuously pumped away through the vacuum exhaust pipe of the vacuum pump, which speeds up the drying speed of the material and finally achieves the purpose of uniform drying.
Disc dryer, also known as disc dryer, or plate dryer (Plate Dryer), is a kind of mechanical stirring conduction drying equipment, developed on the basis of fixed bed conduction dryer and rake type stirring conduction dryer. In the 1950 s and 1960 s, the former Soviet Union had already used it to dry large quantities of lignite. However, due to the low level of industrialization at that time, the price of this complex drying equipment was too high, and it was difficult to promote it to other industries. It was also replaced by a tubular dryer with lower operating cost in the coal industry. The progress and development of the dryer was limited. Tong Rongliang San only cited one example of inorganic salt in the application of disc dryer in his 1975 edition of "Drying Device. By the end of the 1970 s, with the continuous progress of production methods in various industrialized countries, processing costs are no longer the main problem that plagues people. Coupled with the use of new materials and the shortage of energy in the entire range, disc dryers With its outstanding energy-saving advantages, it has once again entered people's field of vision. Germany, Belgium, Japan, the United States, Russia and other countries have specialized companies to research and manufacture disc dryers. Among them, the German Krauss-Maffei Company, which has a long history and is more successful, has developed and manufactured a series of products of TT/TK (normal pressure type), GTT (closed type) and VTI (vacuum type) tray dryers, and has successfully extended it to the chemical, food and pharmaceutical industries, evolving from the eldest black coarse equipment for drying coal to modern fine chemical equipment.
ZPG series battery material horizontal stirring vacuum dryer is the use of water in the material in the vacuum state to reduce the boiling point of the characteristics of the equipment for drying. The equipment uses steam (hot water, heat conduction oil) to heat the jacket indirectly, and the water is evaporated and pumped out in time. Inside the dryer shell, the rake tooth is driven by the transmission shaft, and the rake tooth end is designed to have a certain angle with the axis. The main shaft rotates forward and backward to move the material along the axial direction to facilitate drying and discharging. Two or four percussion rods can be added inside the shell to facilitate the rapid drying and crushing of the material. The percussion rod is a hollow thick-walled stainless steel tube with the same length as the shell, which moves freely inside the shell. The percussion rod continuously knocks the material inside, so that the material is continuously broken (the material obtains a larger specific surface area) to accelerate the drying process, and the quality of the finished material is better.

DXG cylinder cone filter washing and drying three-in-one
The filter washing dryer (commonly known as "three in one" in the industry) can realize the continuous process of material filtration, washing, drying, sterilization and unloading. Its operation mode belongs to batch operation (intermittent operation), which is widely used in pharmaceutical, food, pesticide, chemical and other fields, and can avoid material loss, pollution and environmental pollution caused by material transfer process. The existing three-in-one structure is a flat plate type, but some defects are found in long-term production and use, such as: the circular flat bottom filter area is small; the side discharge, resulting in incomplete discharge; the drying effect is not ideal, and the material in the drying process is turned Small, low heat exchange efficiency, limited drying effect, etc.
DLG type single cone vacuum dryer
The vacuum single cone dryer developed by Yongbang Drying is a high-efficiency multifunctional fully closed vertical vacuum drying equipment integrating decompression distillation, crushing, powder mixing and drying. The drying efficiency of the fully closed vertical vacuum spiral belt dryer is 3-5 times that of the double cone rotary vacuum dryer and vacuum box drying of the same specifications. The vacuum single cone dryer combined with special drying process can adapt to the drying of materials with high viscosity, poor thermal penetration, easy to roll and easy to clump into blocks.
The material enters the bed through the feed inlet, and jumps forward on the air distribution plate under the action of the exciting force provided by the vibration motor or other means. At the same time, the air is heated to a certain temperature after being filtered, and enters the downwind chamber of the dryer through the tuyere. The material is under the dual action of the vibration force and the hot air flow through the air distribution plate, in the suspended state, there is intense turbulence between the material particles and the heat medium in contact with the hot air flow, which strengthens the heat and mass transfer process. The dried product is discharged from the discharge port, and the evaporated water and waste gas are discharged into the atmosphere after dust is recovered by the cyclone separator.
