Moisture protection cabinet for preventing items from oxidation

Abstract

The invention relates to a moisture protection cabinet for preventing items from oxidation, which comprises a cabinet body and a cabinet door, wherein a moisture control host machine and a control panel connected with the moisture control host machine are installed in the cabinet body; the moisture control host machine is composed of two valves, a moisture absorption module arranged between the two valves, and a shape memory alloy spring for connecting the two valves; a heating ring is sheathed on the shape memory alloy spring; a nitrogen gas device is installed outside the cabinet body, and comprises a nitrogen gas tank, an electromagnetic valve and a controller connected with the electromagnetic valve; and the electromagnetic valve is communicated with the cabinet body through a pipeline. The moisture control range of the moisture protection cabinet is 1-60%RH; and the moisture protection cabinet is free from the influence of the outside temperature difference, has the advantages of power saving, no noise and zero material consumption, and conforms to the requirements for energy saving and environment; the molecular sieve can be used repeatedly, thereby saving the energy sources and lowering the production cost; and the invention can enhance the cleanliness in the cabinet body, prevent the stored items from oxidation, accurately control the consumption of nitrogen gas and lower the production cost.

Description

technical field [0001] The invention relates to a moisture-proof cabinet, in particular to a moisture-proof cabinet for preventing articles from being oxidized. Background technique [0002] The humidity of the air changes with seasons and climates. According to research, when the temperature is above 20°C and the humidity is above 60%RH, all kinds of items will become moldy or damp, causing many precision electronic instruments and optical equipment to be damaged. , Calligraphy and paintings, confidential documents and other important valuable items are damaged and cannot be used. Although there are all kinds of moisture-proof boxes, dehumidification sticks, dehumidifiers, etc. on the market, the moisture-proof boxes put desiccant in the airtight container to absorb moisture, although this method can keep the container in a low-humidity state for a limited time , but long-term use requires constant replacement of the desiccant, which not only wastes a lot of resources ...

[0002] The humidity of the air changes with seasons and climates. According to research, when the temperature is above 20°C and the humidity is above 60%RH, all kinds of items will become moldy or damp, causing many precision electronic instruments and optical equipment to be damaged. , Calligraphy and paintings, confidential documents and other important valuable items are damaged and cannot be used

Although there are all kinds of moisture-proof boxes, dehumidification sticks, dehumidifiers, etc. on the market, the moisture-proof boxes put desiccant in the airtight container to absorb moisture, although this method can keep the container in a low-humidity state for a limited time , but long-term use requires constant replacement of the desiccant, which not only wastes a lot of resources and increases the production cost of the enterprise, but also sometimes misses the deadline for replacing the desiccant. At this time, the items to be preserved have already deteriorated or moldy, which affects preservation The quality of the item; the dehumidification stick is easy to generate high temperature, and the dehumidification power is not enough, the humidity cannot be adjusted, and it cannot meet the moisture-proof requirements of different items

In addition, because the air in the cabinet is not clean, it is easy to cause oxidation of the stored items, which affects the normal use of the items.
