Embodiment 1

[0031] Such as figure 1 As shown, an anaerobic drying system includes a rough pumping station, a fine pumping station and a drying tank 210 running on the two stations in sequence. The rough pumping station completes the drying pretreatment, which is mainly used to quickly remove the moisture and oxygen inside the drying tank 210 to meet the requirements of the fine pumping station in the next step.

[0032] The rough pumping station includes a gas buffer pipeline and a dry pump vacuum pipeline; a gas buffer tank 130 is installed on the gas buffer pipeline; an electric heater 120 is installed in the gas buffer tank 130; The quick-drying vacuum pump 330; the large-pumping quick-drying vacuum pump 330 is connected with a cooling circulating water pump 340; the gas buffer tank 130 and the large-pumping quick-drying vacuum pump 330 are connected to the drying tank 210 through a quick self-sealing joint.

Embodiment 2

[0040] Such as figure 2 As shown, an anaerobic drying system includes a rough pumping station, a plurality of fine pumping stations and a drying tank 210 on each station.

[0041] The rough pumping station adopts a dry vacuum pump with high pumping speed and is equipped with a hot nitrogen heating system, which can quickly remove the moisture in the drying tank 210. The typical drying time is 5 to 10 minutes; while the fine pumping station adopts a small-capacity double The rotary vane vacuum pump needs to completely dry the product so that the water and oxygen content in the drying tank 210 can reach a lower target. Generally, the water and oxygen content in the drying tank 210 is required to be lower than 10ppm, and the typical drying time is 1 to 2 hours; The pumping station is adapted to the mode of multiple fine pumping stations, and the automatic production is used to improve the production efficiency. Of course, the production capacity can be further expanded by adapt...

Abstract

The invention provides an anaerobic drying system and a drying method thereof. The anaerobic drying system includes a drying tank, a rough pumping station and a fine pumping station; the drying tank is connected to the rough pumping station or the fine pumping station; the The drying tank is connected with the rough pumping station or the fine pumping station through a quick self-sealing joint. The drying tank is used to hold the product to be dried, the rough pumping station is used for drying pretreatment, and quickly removes the liquid moisture in the drying tank; the fine pumping station is used to completely dry the product, so that the water and oxygen content in the drying tank meets the use requirements . During the drying process, the vacuum degree of the drying tank is monitored throughout the process, and problems such as air leakage in the drying tank can be found in time that lead to product failure. It is convenient to realize automatic production, improves the drying efficiency of the product, and ensures the product quality.

Description

technical field [0001] The invention relates to the technical field of drying, in particular to an anaerobic drying system and a drying method thereof. Background technique [0002] In the chemical industry, electronics and other industries, alloy foils processed and produced in aqueous solution are often involved. These foils have the characteristics of easy oxidation, water absorption, and high temperature failure. After processing, anaerobic drying treatment is required. The traditional treatment method is to put a batch of wet foils into a drying container, moderately heat the surface of the drying container, and at the same time vacuumize the drying container to remove moisture and oxygen in the drying container, and then put the drying container Send it to an oxygen-free environment to take out the foil, and take samples to test the performance of the foil. The traditional implementation method has the following obvious disadvantages: 1) Since the wet state foils will...
