Tunnel vacuum drying equipment

Abstract

The invention discloses tunnel vacuum drying equipment, which comprises a shell, wherein a liner is fixedly connected in the shell; a thermal insulation material is filled between the liner and the shell; two ends of the shell and the liner are connected with isolating doors; an air inlet / outlet is formed and a steam heating device and a condensate water cooling device are arranged on an inner cavity; a temperature control device is arranged on the inner cavity; rollers are connected in the inner cavity; vacuum box bodies are connected on the rollers and are provided with sealing doors; pipelines are fixedly connected on the vacuum box bodies; valves are arranged on the pipelines; and two or more pieces of tunnel vacuum drying equipment are matched. Materials to be dried can be strictly controlled according to process flows and are subjected to monitoring management and production in a centralized mode in batches by stages, and the quality of products can be guaranteed; meanwhile, manual labor and workshop space are saved, fund and energy are saved, and the equipment is environment-friendly.

Description

technical field [0001] The invention relates to a vacuum drying device, in particular to a tunnel vacuum drying device. Background technique [0002] At present, my country's lithium battery is developing rapidly in the new energy industry.

The rapid expansion of the production capacity of the lithium battery industry has led to the rapid development of the lithium battery production equipment manufacturing industry. Energy saving and consumption reduction is the key to the development of lithium battery vacuum drying equipment. The energy shortage has attracted the attention of the whole world. Electric heating lithium battery vacuum drying equipment technology is to put the vacuum box into the heat preservation oven for welding and fixing, and use electric heating to blow hot air to heat the surface of the vacuum box from normal temperature to high temperature. After the electric heating tube is powered off, the vacuum box is kept warm Standing in the oven for natural cooling from high temperature to normal temperature, the oven takes a long time to heat and cool the vacuum box during production, and consumes a lot of power, resulting in a long production cycle for a single process, and repeated heating of the oven during batch cycle production and cooling, resulting in loss of heat energy, which cannot be fully utilized and does not save energy
