Efficient energy-saving internal heating vacuum baking intelligent system

Abstract

The invention discloses an efficient energy-saving internal heating vacuum baking intelligent system which comprises a preheating box group, a thermostat group, a cooling box group, a transitional box group, a plurality of brake valves, a transmission system and a control system, wherein the preheating box group comprises a plurality of preheating boxes sequentially connected in sequence; the thermostat group comprises a plurality of thermostats sequentially connected in sequence; the cooling box groups comprises a plurality of cooling boxes sequentially connected in sequence; the transitional box group comprises a first transitional box, a second transitional box, a third transitional box and a fourth transitional box; and the brake valves are arranged at two ends of the first transitional box, the second transitional box, the third transitional box and the fourth transitional box. Through the manner, the efficient energy-saving internal heating vacuum baking intelligent system adopts an internal heating system; independent intelligent temperature control is carried out on four internal surfaces; a lithium battery is uniformly heated to precisely control temperature so as to prevent the phenomena that a product is low in quality and is even scrapped due to the temperature problems including temperature overshoot and temperature instability; the entire baking system is full vacuum, less in heat consumption, high in heat efficiency and more efficient and energy-saving.

Description

technical field [0001] The invention relates to the technical field of lithium battery manufacturing, in particular to a high-efficiency energy-saving internal heating vacuum baking intelligent system. Background technique [0002] Lithium batteries have the advantages of high voltage, large specific energy, long charge and discharge life, and safety and environmental protection.

Problems solved by technology

[0007] The technical problem mainly solved by the present invention is to provide a high-efficiency and energy-saving internal heating vacuum baking intelligent system. By adopting the internal heating system, the internal four sides can be independently intelligently controlled for temperature, and the temperature uniformity is good. The lithium battery is evenly heated to ensure its consistency. , accurate temperature control, there will be no phenomenon of low product quality or even scrapping due to temperature problems such as temperature overshoot and instability. During the baking process, the heating speed is greatly increased, the lithium battery is heated faster, and the production process time is reduced. , the whole baking system is full vacuum, less heat loss, high thermal efficiency, more efficient and energy-saving
