Description

Technical Field

[0001] This utility model relates to the field of oxygen generator technology, specifically to an oxygen generator with automatic start and stop. Background Technology

[0002] The principle of industrial oxygen generation equipment is based on air separation technology. First, air is compressed to a high density, then the different condensation points of the air components are used to separate the gas and liquid components at a specific temperature. Further distillation yields the oxygen. In existing technologies, oxygen generators require manual monitoring of the gas tank's capacity at regular intervals, and the operation and shutdown of the equipment are controlled based on this capacity. This increases the labor intensity of workers and reduces the level of automation in production. Therefore, this paper proposes an automatic start-stop oxygen generator that can improve automated production. Summary of the Invention

[0018] Below, we will combine the appendix... Figure 1-3 The present invention provides a further description of an oxygen generator with automatic start-stop function.

[0019] It should be noted that all directional indications in the embodiments of the present invention, such as up, down, left, right, front, back, etc., are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indication will also change accordingly.

[0020] See appendix Figure 1-3As shown, this embodiment of an automatically starting and stopping oxygen generator includes an air compressor 1, a high-efficiency oil separator 2, a refrigerated dryer 3, a filter 4, a buffer storage tank 5, an oxygen generating device 6, a dust filter 7, an oxygen buffer tank 8, and a storage tank 9 connected in sequence. The characteristic feature is that the storage tank 9 is equipped with a sensor 901 for sensing the pressure inside the storage tank 9 and a controller 902 connected to the sensor 901 and the oxygen generating device 6. The storage tank 9 is composed of several tank bodies 903 and pneumatic partition seats 904 installed between the tank bodies 903 in a tight fit. The sensor 901 can be an electrical contact pressure gauge. By using the sensor 901 to sense the pressure of the gas in the gas storage tank 9 in real time, the sensor sends the signal to the controller 902. The controller 902 controls the oxygen generator 6 to work and stop according to the set pressure, thereby realizing automated production, improving production efficiency, and reducing the labor intensity of workers. The pneumatic separator 904 can separate or connect the tanks 903, adjust the space for storing gas inside the gas storage tank 9, and can also allow multiple oxygen generators 6 to be connected and used at the same time, reducing the area occupied by the equipment.

[0021] See appendix Figure 3 As shown, the pneumatic partition seat 904 includes a partition base 905, a partition plate 906 rotatably mounted on the partition base 905, and a rotary cylinder 907 for driving the partition plate 906 to rotate. The partition base 905 is provided with a mounting boss 908 adapted to the tank body 903. Sealing rings 909 are installed on both the mounting boss 908 and the partition plate 906. Each tank body 903 is provided with an air inlet channel 910 and an air outlet channel 911. Control valves 10 are installed on both the air inlet channel 910 and the air outlet channel 911. The rotary cylinder 907 drives the partition plate 906 to rotate, thereby connecting or separating the tank bodies 903.

[0022] See appendix Figure 1 As shown, the filter includes a precision filter 4 and an activated carbon filter 401; the high-efficiency oil remover 2, the refrigerated dryer 3, the filter, the buffer gas tank 5, the dust fine filter 7, the oxygen buffer tank 8, and the gas tank 9 are all connected to a drain pipe 11; a control valve 10 is connected between the high-efficiency oil remover 2, the refrigerated dryer 3, the filter, the buffer gas tank 5, the dust fine filter 7, the oxygen buffer tank 8, and the gas tank 9 and the drain pipe 11.

[0023] In the working process of this utility model, the air compressor 1 delivers air to the high-efficiency oil separator 2 for oil removal. The oil-removed air is then dried in the refrigerated dryer 3. After drying, the air passes through a precision filter 4 and an activated carbon filter 401 for filtration. The filtered air then enters a buffer storage tank 5 for storage. The air in the buffer storage tank 5 is then delivered to the oxygen generator 6 for oxygen production. The oxygen produced by the oxygen generator 6 passes through a dust filter and enters an oxygen buffer tank 8. Finally, it is stored in a storage tank 9. The sensor 901 on the storage tank 9 senses the oxygen pressure in the storage tank 9 in real time. When the oxygen in the storage tank 9 is being produced, if the sensor 901 senses that the gas pressure in the storage tank 9 is lower than the set minimum pressure, the controller 902 controls the oxygen generator 6 to continue producing oxygen. During the oxygen production process, if the sensor 901 senses that the gas pressure in the storage tank 9 is higher than the set maximum pressure, the controller 902 controls the oxygen generator 6 to stop producing oxygen.

[0024] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
