Volume: 5 cubic meters Lithium iron phosphate cathode material dryer

Working principle of a 5 cubic meter lithium iron phosphate positive electrode material dryer
The volume is 5 cubic meters. The lithium iron phosphate positive electrode material dryer is a double-cone rotating tank body. Under vacuum conditions, heat transfer oil or hot water is introduced into the jacket for heating, and the heat is transferred through the inner wall of the tank to contact the wet material. The water vapor or other gases evaporated after the wet material absorbs heat are extracted through the vacuum pump via the vacuum exhaust pipe. Since the tank is in a vacuum state and the rotation of the tank causes the material to continuously move up and down, as well as turn inside and out, the drying speed of the material is accelerated, the drying rate is improved, and uniform drying is achieved.

The volume of the biconical shape is 5 cubic units.

Inner wall temperature of the double-cone cylinder: room temperature to 170°C (heated by thermal oil, which is to be provided by the purchaser). The heating structure of the thermal oil tank (container) is designed to be reasonable, reliable, and durable.

Vacuum degree (pressure inside the tank): can reach -0.09 to -0.095 MPa. The tank must be well sealed to prevent powder oxidation and spoilage.

Inner liner: SUS304 Surface coating (wear-resistant, resistant to pH 7-11 powder, and withstands high temperatures of 170-200°C). The drying process does not introduce magnetic substances such as chromium, nickel, or elemental iron (the increase after drying is ≤30 ppm).

The vacuum system bag filter consists of a perforated plate with temperature-resistant coated filter bags, followed by filtration, condensation, and buffer devices.

After drying, the moisture content of the powder shall be ≤500ppm (tested according to GB/T6283 method). Operating environment: ≤30% drying room (provided by the purchaser).

24h (including heating and cooling time) output: ≥2500kg.
