Description

Technical Field

[0001] The invention relates to an oxygen concentrator, in particular to a constant temperature static chamber for assembling and testing an oxygen concentrator. Background Art

[0002] The Qinghai-Tibet Plateau is the largest plateau in China and the highest in the world. Due to its high altitude, the air on the Qinghai-Tibet Plateau is relatively thin, especially the oxygen content. People from low-altitude areas often suffer from altitude sickness due to lack of oxygen when they go to the Qinghai-Tibet Plateau. In areas where people gather, oxygen concentrators are usually set up indoors or outdoors to add oxygen. Oxygen concentrators can not only be used on the plateau, but hospitals also have a great demand for oxygen concentrators. For people living on the plateau, especially those who do physical work, they need to carry an oxygen concentrator with them to avoid special circumstances where they need to use oxygen.

[0003] Oxygen generator is a type of machine that produces oxygen. Its principle is to use air separation technology. First, the air is compressed at a high density, and then the different condensation points of the components in the air are used to separate the gas and liquid at a certain temperature, and then further distilled. The traditional oxygen generator uses the adsorption performance of molecular sieves, and through physical principles, uses a large-displacement oil-free compressor as the power to separate nitrogen and oxygen in the air, and finally obtains high-concentration oxygen. This type of oxygen generator produces oxygen quickly and has a high oxygen concentration. It is suitable for oxygen therapy and oxygen health care for all kinds of people.

[0004] During the production and assembly process of the oxygen generator, a strict control environment is required, and each link of the equipment process needs to be strictly controlled. Therefore, a separate constant temperature static room is needed. In addition, testing is required after assembly, which also requires such a constant temperature static room. The constant temperature static room needs to control the indoor temperature, humidity, wind speed, etc. Even some special parts assembly and testing require clean gold and the amount of dust. However, the current constant temperature static only takes into account the static environment, and does not take into account the dynamic environment during work. Moreover, it is very difficult to control the real-time changes in the dynamic environment. Now there is no constant temperature static room that can be dynamically controlled. Summary of the invention

[0005] The object of the present invention is to provide a constant temperature static chamber for oxygen generator assembly and testing, so as to solve the problem that the existing constant temperature static chamber has no dynamic control.

A group of wind shield boxes 12 shares a group of main ducts 15, and the main ducts 15 include hot air main ducts and cold air main ducts.

[0033] Embodiment 4:

[0034] On the basis of the above-mentioned embodiment, in this embodiment, a special working area 3 is provided below the wind shield box 12 where a constant wind speed is required for special control.

[0035] Embodiment 5:

[0036] On the basis of the above embodiments, in this embodiment, in order to adapt to the control and the control of wind speed, the wind hood 13 is configured as an arc-shaped hood, and two branch pipes 14 are arranged on the top thereof and are respectively connected to the hot air main pipe and the cold air main pipe. A solenoid valve 4 and a flow meter 5 are arranged in the branch pipe 14. In order to filter the fresh air, a filter 6 is arranged in the wind hood 13. A medium-efficiency filter is selected as the filter 6, and a gas distributor 7 is arranged under the filter 6 to disperse the gas.

[0037] Embodiment 6:

[0038] On the basis of the above-mentioned embodiment, in this embodiment, air outlets 11 are arranged around the working area 1 corresponding to the wind shield boxes 12 .

[0039] Embodiment 7:

[0040] On the basis of the above embodiment, in this embodiment, in order to prevent the system from overloading, a pressure sensor 26 is provided on the main pipeline 15 .

[0041] Embodiment 8:

[0042] On the basis of the above embodiment, this embodiment provides a specific embodiment, in which the number of wind shields 13 of the device is set to 9, and the specific operation is as follows:

[0043] 1) A unified controller is set up in the system equipment area. The controller has a display screen to display various parameters, including air volume, temperature and humidity, including real-time detected temperature and set temperature;

[0044] 2) Connect the constant temperature and humidity equipment including industrial air cooler 21, air heater 22, air pump 23, industrial humidifier 25, temperature sensor, humidity sensor, solenoid valve 4, flow meter 5, and pressure sensor 26 to the controller. The switch of each device is displayed on the display screen through electrical connection;

[0045] 3) Number the 9 wind shields 13 in an "S" shape, from 1 to 9. The special requirement area of ​​this embodiment is issued under the No. 4 wind shield 13, marked with the number 4 of the special work area 3 and displayed on the display screen;

[0046] 4) A group of temperature and humidity sensors are arranged under each corresponding number and numbered, the number of which corresponds to the number of the wind hood 13;

[0047] 5) Set up a new pipeline to connect to the wind hood 13 numbered 4 in the special work area 3;

[0048] 6) An infrared sensor is provided under the corresponding wind shield 13 and connected to the controller with the corresponding number.

[0049] In this embodiment, the initial temperature is set to 18 to 22 degrees Celsius, the initial humidity is set to 35% to 65%, and the initial fresh air volume is set to 30 cubic meters per hour. The pressure is calculated based on this. Because there is no pressure difference, the initial pressure is set to 0.01MPa to 0.1MPa. When the pressure of the pressure sensor is greater than 3 times the maximum value and keeps increasing, the air volume input of the air pump is controlled. A simple calculation method is to set the number of people in the room to 10, set the total input air volume of the air pump 23 to be not less than 300 cubic meters per hour, and evenly distribute it to each wind hood and round up to 36 cubic meters per hour. Then, the input volume per second is 0.01 cubic meters, the wind speed is 10 meters per second, and the wind pressure is 60Pa. Therefore, it is very reasonable to set the initial pressure size to 0.01MPa to 0.1MPa.

[0050] During the control process, when the temperature is greater than the set value, cold air is supplied; when the temperature is lower than the set value, hot air is supplied; when the humidity is greater than the set value, hot air or constant temperature air is supplied to discharge the humidity in the air from the air outlet; when the humidity is lower than the set value, the humidifier is started for humidification.

[0051] When the equipment is in working state, or when someone passes under the hood, the operation of the equipment will inevitably cause changes in wind speed and increase in temperature in the space. When the equipment is working, the wind pressure and speed are increased, and the temperature is reduced through rapid ventilation. The wind speed in a specific area needs to be constant, so the supply of cold air is increased. At the same time, infrared rays will detect whether there are people. When someone passes by, the supply of cold air is increased under the hood. The wind speed of the hood is controlled by the switch of the solenoid valve.
