Embodiment Construction

[0017] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0018] see figure 1 , the present invention provides a novel micro-positive pressure transport box, comprising a gas cylinder 1 and a hollow box body 5;

[0019] The gas cylinder 1 and the box body 5 are connected through a hollow pipeline;

[0020] An on-off ball valve 2 and a pressure reducing valve 3 are arranged on the pipeline between the gas cylinder 1 and the box body 5 .

[0021] In the present invention, it should be noted that the gas cylinder 1 is pre-filled with dry air (such as nitrogen), and the gas cylinder 1 outputs the dry air to the box 5 through a hollow pipeline.

[0022] In terms of specific implementation, the gas cylinder 1 is preferably a nitrogen cylinder, and its working pressure can range from 0 to 15 MPa. Among...

Abstract

The invention discloses a novel micro-positive-pressure transportation box. The novel micro-positive-pressure transportation box comprises an air cylinder (1) and a hollow box body (5); the air cylinder (1) communicates with the box body (5) through a hollow pipeline; and the pipeline between the air cylinder (1) and the box body (5) is provided with a switch ball valve (2) and a decompression valve (3). The novel micro-positive-pressure transportation box disclosed by the invention can guarantee that a micro-positive-pressure environment can be maintained inside the box body in a short-distance transportation process, realizes a long pressure-maintaining time, is beneficial for wide production and application, and has great production practice significance.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to a novel micro positive pressure transport box. Background technique [0002] At present, for some items, a dry environment is required during transportation, so they need to be placed in a transportation box for sealed transportation. At this time, if the environment of the transport box is slightly positive pressure, the sealing time will be short, and if the positive pressure is too high, the quality of the box will be high, the weight will be heavy, the cost will be high, and the safety will be poor. For example, for the pole pieces of current lithium-ion batteries, it is necessary to ensure the dryness in the transport box during the transshipment process, usually for short-distance transport (that is, the transshipment time is about 2 hours). [0003] It should be noted that the situation where the pressure is 200-400 Pa higher than the atmospheric pressure is called slig...
