Tunnel vacuum drying equipment

Abstract

A tunnel vacuum drying equipment, which includes: an outer shell, an inner liner is fixedly connected to the outer shell, insulation material is filled between the inner liner and the outer shell, isolation doors are connected to both ends of the outer shell and the inner liner, and an air inlet and outlet are provided on the inner cavity , steam heating device and condensed water cooling device, a temperature control device is installed on the inner cavity, a roller is connected to the inner cavity, a vacuum box is connected to the roller, and a sealed door is installed on the vacuum box. There are pipelines fixedly connected, and valves are installed on the pipelines; the tunnel vacuum drying equipment is used in conjunction with two or more. The invention can strictly control the drying materials according to the technological process, and centrally monitor, manage and produce in stages and batches, which can better ensure product quality, save manpower and workshop space, save funds, save energy, and is beneficial to environmental protection.

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. From the initial mobile phone lithium battery to the current new energy vehicle power battery, the huge market space has made domestic enterprises involved in the field of new energy batteries spring up in recent years. From a few factories in the late 1990s to more than 400 factories now, the huge market prospect has led most companies to announce capacity expansion plans. 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 ...

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
