Problems solved by technology

[0003] The existing vacuum oven has a better drying effect on loose solid particles, but it does not have a good drying effect on solids with relatively dense surfaces, porous materials, and small voids, such as battery pole pieces, especially for the interior and the tighter combination. The moisture cannot be removed and cannot meet the higher requirements of these industries, so that it forms a bottleneck in the production of some electronics industries and has a profound impact on the quality of its products

Embodiment 1

[0033] An amplitude-modulated vacuum drying oven, comprising a drying oven box body 1 and a drying inner chamber 2 arranged in the box body, and a vacuum air conditioning controller 3, and the drying oven box body 1 is provided with a drying inner chamber 2 The vacuum port 21 connected with the vacuum pump, and the air inlet 22 connected with the drying inner cavity 2 and used for connecting the dry gas; a vacuum port valve 23 is provided between the vacuum port 21 and the vacuum pump, and the air inlet An air inlet valve 24 is provided between the port 22 and the dry gas source, and the vacuum air conditioning controller 3 is connected to the vacuum interface valve 23 and the air inlet valve 2 respectively, and is controlled to open or close.

[0034] The vacuum air conditioning controller is composed of a precise pressure sensor, a precision solenoid valve and a flow meter. The precision pressure sensor measures the vacuum degree in the inner cavity of the oven. The valve co...

Embodiment 2

[0039] An amplitude-modulated vacuum drying box, comprising a drying box body 4 and a drying inner cavity 5 arranged in the box body, and also includes a piston device 6 that can be stretched inside the drying box, and the piston device can be telescopically reciprocated in the drying box The back and forth movement of the device, the piston movement of the device, makes the volume in the container increase and decrease regularly, so that the gas pressure in the container changes regularly. Through regular vibration, the water molecules are accelerated to detach from the micropores on the surface of the material, and then they are effectively drawn out of the drying container, so as to speed up the desorption and desorption process of the absorbed water in the dried material, so as to achieve faster water removal, more thorough drying, and dehydration. Water effects better technical effects.

[0040] After testing with a moisture meter, and recording the time required to dry t...

Abstract

The invention discloses a deep drying method. By means of the method, the vacuum degree and / or air pressure intensity inside a container used for containing substances to be dried are changed regularly, the regular change of the vacuum degree and / or air pressure enables water molecules to break away from micro holes in the surfaces of the substances more rapidly, then the water molecules are pumped out of the drying container effectively, desorption of the absorbed water inside the substances to be dried is accelerated, and therefore the technical effects of being faster in water removal, more thorough in drying and better in water removal effect are achieved. The invention further discloses an amplitude-regulating type vacuum drying box. The deep drying method and the amplitude-regulating type vacuum drying box achieve the technical effects of being faster in water removal, more thorough in drying and better in water removal effect, can be applied to some electronic industries, and break through the bottleneck caused by water on the industries.

Description

technical field [0001] The invention relates to the drying field, in particular to a deep drying method and an amplitude-modulated vacuum drying oven. Background technique [0002] At present, in the field of drying, heating, decompression and freezing are often used to dry solids. The most common methods are ovens, vacuum ovens, etc., and vacuum ovens have better drying effects. The application process of the vacuum oven is to place the dry material in a closed drying room, and heat the material to be dried while vacuuming with a vacuum system, so that the moisture inside the material diffuses to the surface through the pressure difference or concentration difference, and escapes into the vacuum chamber The low-pressure space is thus pumped away by the vacuum system. During the vacuum drying process, the pressure in the drying chamber is always lower than the atmospheric pressure, the number of gas molecules is small, the density is low, and the oxygen content is low, so i...
