Double Layer High Vacuum Oven (TOB-GZK02-D1)

Overview

TOB-GZK02-D1 Double Layer High Vacuum Oven by TOB NEW ENERGY is equipment used for lithium battery cell and electrode dehydrating and drying. Item no. TOB-GZK02-D1, order(moq) 1, Payment L/C, T/T, product origin China, shipping port XIAMEN. The oven has two independent inner cavities sized H 350 mm*W 1350 mm*D 600 mm*2 Layers (subject to real oven) and overall dimensions H 2000 mm*W 1800 mm* D 1400 mm (subject to real oven). The shell is A3 cold rolled steel plate with baking paint (colors white and grey, orange customize), the interior is stainless steel industry wire drawing board thickness: 4.0 mm, and the door is a single side door with an open mold casting form Silicone rubber O-ring for high temperature and corrosion resistance. The internal air transport structure adopts magnetic fluid for air transportation, providing sealing performance and high temperature resistance. Vacuum and gas interfaces are located at the rear: vacuum interface KF40 and dry air interface 12 mm air pipe interface. Vacuum degree: no-load cavity ≤ 10 Pa, full-load cavity 50 Pa -- 100 Pa, air leakage for 24 hours ≤ 500 Pa. Heating uses internal and external double circulation wind with internal and external double heat source dual-control through heat radiation, conduction and electric heating control; external structure is U type circulating air (left air out, right air suction, upper and lower side exhaust) and internal structure uses a dual duct principle. Main heating temperature control accuracy is within ±0.5℃ and temperature error inside the box is ±2℃ (empty box, constant temperature state); temperature range is Room temperature +10℃~150℃ and temperature rise speed is Room temperature ~85℃ ≤30 minutes (atmospheric pressure, no-load state). Temperature stability time in the furnace is 60 -90 minutes (empty). Cooling is available via an optional cold air system connected to an outer air duct with alternate cooling by vacuum nitrogen; cooling time ≤30 minutes (empty box, 100℃~60℃) and full load test time ≤120-150 min (depends on the product size). Box surface temperature when the furnace is 100℃ is ≤ room temperature +15 ℃. Control mode is PLC automatic control with touch screen operation and automatic program control for heating, vacuum pumping and nitrogen injection. Each layer operates independently for heating, vacuuming and nitrogen filling. Security protections include cavity overtemperature automatic shutdown, electric heating pipe overcurrent and short circuit protection, internal circulation fan overcurrent and short circuit protection, control system overcurrent and short circuit protection, a special explosion-proof door with overpressure self-relief, automatic closure of nitrogen & dry gas inlet when the inner cavity is overcharged, and an independent sound and light alarm timing function. This oven is used for dehydrating and drying lithium battery cells and electrodes. Each machine can work in a continuous cycle where the operator opens the door, places the electrode into the oven, and sets heating time, vacuum time and nitrogen time. The system automatically completes heating and regular ventilation according to those set time parameters under PLC program control with manual/automatic switching and touch screen operation, and each of the two layers can independently perform heating, vacuuming and nitrogen filling.
