Description

Technical Field

[0001] This patent relates to the technical field of closed storage containers, and specifically to a closed metal storage container that monitors environmental and object changes in real time. Background Art

[0002] Since metals or metal products are corroded during storage, resulting in a large amount of metal loss or the metal products losing their application effect, the corrosion of metal materials is generally controlled by adjusting the medium environment, but this method cannot achieve long-term storage and real-time monitoring of its state. At present, most of the closed storage containers cannot control the environment and temperature changes inside the container space after sealing, and cannot realize real-time monitoring, data recording and reading functions of the storage environment. In addition, most storage containers today are designed for liquid and gas storage, while there are few storage containers for solid metals. At the same time, most existing solid storage containers are a tank body. By injecting an inert gas with a density greater than that of air into the tank body, the inert gas squeezes out the air in the tank body to prevent the metal in the tank body from being oxidized. However, this type of storage container cannot achieve miniaturization design, real-time monitoring and environmental control of the atmosphere changes in the internal space of the storage container and the changes in the metal corrosion state.

[0003] Therefore, it is necessary to develop a storage container that can realize miniaturization and real-time monitoring of the changes of samples and atmosphere inside the storage container. The small sample storage device consists of a storage container system, a vacuum system, a detector system, a weighing system, a bottom moving mechanism, a mobile operating table, a data storage unit, etc. The storage container can realize miniaturization of the storage container, internal atmosphere control, internal temperature control, and centralized display of real-time measurement parameters. Summary of the invention

[0004] The purpose of the present invention is to design a miniaturized storage container that can realize long-term storage of metals or metal products and reduce their corrosion during storage, while having real-time monitoring of sample changes and precise control of the internal temperature, humidity and ambient atmosphere of the storage container, in view of the fact that storage containers cannot be miniaturized, the internal temperature and atmosphere cannot be precisely controlled, and the status of samples inside the container cannot be monitored in real time.

[0005] The technical solution of the present invention is as follows: a closed metal storage container for real-time monitoring of environmental and item changes, comprising a storage container, a weighing unit at the bottom of the storage container; a side wall of the storage container with an interlayer, and a liquid heat-conducting medium in the interlayer; and a tray is placed in the internal chamber of the storage container;

[0006] The storage container is equipped with an oxygen sensor, a hydrogen sensor, a pressure sensor, an absolute humidity sensor, a temperature sensor, and a pressure gauge;

[0007] The storage container is connected to the air inlet and outlet of the storage container;

[0008] A humidity controller is also included.

[0009] The storage container is also equipped with a temperature control component, which heats the liquid heat-conducting medium in the side wall interlayer of the storage container;

[0010] The storage container is topped with a glass sealing cover.

[0011] The tray consists of three layers: upper, middle and lower.

[0012] A backup sensor is provided for each absolute humidity sensor and temperature sensor.

[0013] The humidity controller comprises an air inlet, a circulating fan, a clamp and an air outlet. The humidity controller is connected with the air inlet and the air outlet of the storage container through the air inlet, and there is a saturated salt solution or a desiccant in the humidity controller.

[0014] The weighing unit comprises a ceramic fiber weighing platform and a weighing unit body, and the lower end of the weighing unit body is connected with a rubber shock absorber.

[0015] The side walls and bottom of the storage container are designed with a labyrinth-type ceramic fiber insulation layer.

[0016] The storage container also includes a polyimide electric heating film auxiliary heating cover.

[0017] Maintain the temperature in the storage container at 30°C.

[0018] The remarkable effects of the present invention are:

[0019] 1. The present invention can accurately control the temperature in the container. The bottom of the container is filled with heating liquid and the top is a heating cover. The above design can ensure that the temperature inside the container is evenly distributed, and there will be no temperature difference phenomenon that affects the application effect of the container.

[0020] 2. The storage device formed by the present invention can be designed to be miniaturized, so that the storage container occupies a small area, and multiple storage containers can be monitored centrally.

[0021] 3. The present invention can accurately control the humidity and atmosphere changes inside the storage container, thereby reducing the corrosion of the metal in the storage container and achieving long-term storage of the metal.

[0022] 4. The present invention can realize real-time monitoring of samples in storage containers and accurately understand the corrosion changes of metals. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The storage container 7 is connected with an oxygen sensor 1 and a hydrogen sensor 2 to monitor the hydrogen and oxygen content inside the storage container 7;

[0035] An absolute humidity sensor 4 is installed on the storage container 7 to monitor the humidity inside the storage container 7;

[0036] A temperature sensor 5 is installed on the storage container 7 to monitor the temperature inside the storage container 7;

[0037] The absolute humidity sensor 4 and the temperature sensor 5 are each provided with a backup sensor;

[0038] The storage container 7 is equipped with a pressure sensor 3 and a pressure gauge 12 to monitor the pressure inside the storage container 7;

[0040] The device also includes a humidity controller 8, such as Figure 2 As shown, the humidity controller 8 includes an air inlet 8-1, a circulating fan 8-2, a clamp 8-3, and an air outlet 8-4. The humidity controller 8 is connected to the air inlet and outlet 11 of the storage container through the air inlet 8-1, and there is a saturated salt solution or a desiccant in the humidity controller 8. According to the monitoring condition of the humidity in the storage container 7 by the absolute humidity sensor 4, the humidity controller 8 selects a saturated salt solution or a desiccant, and blows the wet or dry gas into the storage container 7 through the circulating fan 8-2, thereby controlling the humidity in the storage container 7;

The lower end of the weighing unit body 10-2 is connected to a rubber shock absorber 9. The rubber shock absorber 9 makes the upper and lower pressures of the storage container 7 consistent to avoid vibration.

[0043] The side walls and bottom of the storage container 7 are designed with a labyrinth-type ceramic fiber insulation layer to prevent temperature.

[0044] The specific steps taken by the present invention are as follows:

[0045] (1) Turn on the power switch on the electric control cabinet of the mobile operating table and start the test after the industrial integrated machine is turned on and preheated.

[0046] (2) Open the software and wait for the cooling fan to automatically start, then set the temperature to 30°C.

[0048] (4) Place the sample on the material platform bracket, cover it with the sealing cover and tighten the sealing clamp.

[0049] (5) Place the prepared saturated salt solution or desiccant into the humidity controller, connect the power supply and turn on the exhaust fan to circulate the air in the sealed chamber to accelerate the humidity to reach equilibrium.

[0050] (6) After the temperature and humidity of the small sample storage device reach the test conditions, the weight, hydrogen, pressure and other parameters are collected in real time.

[0051] (7) After the test is completed, check whether the data is saved.
