Special dryer project for lithium iron phosphate

project description:

  In recent years, China's lithium battery output has increased significantly. As of the end of 2012, the output of lithium-ion batteries reached 1.875 billion. Lithium battery cathode materials have also evolved from a single lithium cobalt oxide material to a stage where materials such as lithium cobalt oxide, lithium manganate, lithium nickel cobalt oxide, lithium nickel cobalt manganate, lithium iron phosphate, etc. go hand in hand. Driven by the growth of the lithium battery market, the overall market for lithium battery materials is on the rise, and the progress made in the research of lithium battery cathode materials shows that its market prospects are broad.
  Lithium iron phosphate is a new material that initiates the lithium battery revolution industry, and is the forefront of the development of the lithium battery industry. Due to its own advantages, lithium iron phosphate batteries are widely used in various fields such as hybrid vehicles, electric tools, electric white driving vehicles, electric bicycles, power generation and energy storage devices. Hybrid electric vehicles (HEV) are the main development direction of new energy vehicles in the next few years. With the continuous increase in the output of hybrid electric vehicles and the increase in the share of hybrid electric vehicles, the market scale of lithium iron phosphate batteries will grow rapidly.
  Lithium iron phosphate--a new type of cathode material for lithium-ion batteries.
  The performance of lithium-ion batteries mainly depends on the anode and cathode materials. As a new cathode material for lithium-ion batteries, lithium iron phosphate has obvious advantages over other cathode materials in safety performance and cycle life. These are also important technical indicators for power batteries. Lithium iron phosphate has the advantages of non-toxic, harmless, good safety and long life, and has become one of the ideal cathode materials for a new generation of lithium-ion batteries.

The main application areas of lithium iron phosphate:

  (1) Energy storage equipment: energy storage equipment based on solar, wind, geothermal, and ocean energy power generation systems; grid peak shaving; uninterruptible power system UPS; use with solar cells as energy storage equipment; household lighting, etc.
  (2) Electric tools High-power electric tools (wireless); electric hammers, electric drills, weeders, etc.
  (3) Light-duty electric vehicles Electric vehicles, electric bicycles, recreational vehicles, golf carts, electric lifts, cleaning vehicles; hybrid electric vehicles (HEV), a goal in the near 2-3 years, forklifts, forklifts and other power sources.
  (4) Small equipment medical equipment: electric wheelchairs, electric scooters; toys (remote control electric planes, cars, boats).
  (5) Other small electrical appliances, miner’s lamps.
  (6) Starting power supply: starting power supply for automobiles, motorcycles, tractors, diesel engines, railway diesel locomotives, electric locomotives, and passenger cars;
  (7) Fixed power supply: used in communications, mobile base stations, telecommunications, railway transportation, electricity, finance, power plants, and computer systems as backup power sources for protection and automatic control.
  (8) Military field: military field electronic command system, sea (submarine. underwater robot), land (army system. robotic warrior), sky (unmanned aircraft), air (satellite. spacecraft) various arms. Lithium-ion battery technology is no longer just an industrial technology. The development of its related information industry is one of the basic technologies for the development of the new energy industry, and it has become one of the important "food" indispensable for modern and future military equipment. I believe that in the near future, lithium iron phosphate batteries will replace lead-acid batteries to dominate the world of power batteries, and the applications will be more extensive!
  According to the material characteristics of lithium iron phosphate, the company independently developed a lithium iron phosphate double cone vacuum dryer on the basis of digesting and absorbing better foreign equipment and technology.

         The working principle of the equipment:
A heat source is introduced into the airtight interlayer, and the heat is transferred to the material to be dried through the inner shell; driven by power, the tank body rotates slowly, and the material in the tank is continuously mixed to achieve the purpose of strengthening; the material is in a vacuum state, and the air pressure drops The solvent on the surface of the material is saturated and evaporated, and it is discharged by the vacuum pump in time. The solvent inside the material continuously penetrates, evaporates, and discharges to the surface. The three processes are carried out continuously, and the material achieves the purpose of drying in a short time.
         Device Description:
  (1) The equipment is composed of a host, a motor, a rotary joint, and a reducer.
  (2) A Φ400 manhole is installed on the top of the equipment, and the discharge port is equipped with a stainless steel butterfly valve, which can control the discharge flow and is easy to operate.
  (3) Set and control the required temperature according to the process requirements, and use hot water or steam heating according to the set temperature range, and the heating system is prepared by the user.
(4) The material to be dried is put into the dryer. Under vacuum conditions, the material is constantly turned over and receives heat from the inner surface of the contacting vessel wall, thus speeding up the drying of the material. It saves 1/3 of the time compared to static vacuum dryers and improves Labor productivity.
