Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of protection devices, in particular to a nitrogen protection gas adding device for industrial oxygen compression safety control. Background Art
[0002] Oxygen compressors are widely used in industry, primarily for the compression, storage, and delivery of oxygen. They mechanically extract oxygen from the air and pressurize it to meet the demand for oxygen in various industrial, medical, and scientific research fields. Oxygen compressors typically handle high-pressure gas during operation, making their safety particularly important.
[0003] However, oxygen compressors present numerous safety hazards in actual operation, particularly during operation and startup. Inadequate internal degreasing and cleaning, or improper operation, can easily lead to fires and explosions. High concentrations of oxygen, under certain conditions, can accelerate combustion, causing flames to spread rapidly, posing a serious threat to equipment and personnel. Furthermore, the high pressure of oxygen makes equipment more susceptible to accidents, such as cylinder rupture or leaks, further exacerbating safety risks. Utility Model Content
[0004] The purpose of the utility model is to provide a nitrogen protective gas adding device with safe control of industrial oxygen compression, so as to solve the problems raised in the above background technology.
[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a nitrogen protective gas addition device with safe control of industrial oxygen compression, comprising a bottom box, a bottom plate fixed to the external bottom surface of the bottom box, a reversing valve provided at one end of the internal front end of the bottom box, the top end of the reversing valve being connected to one end of a first solenoid valve through a fourth pipe, and the other end of the first solenoid valve being connected to the output end of a first gas tank, the first gas tank being arranged at one end of the internal rear end of the bottom box, a partition being fixed in the middle of the interior of the bottom box, and a top box being fixed to the top end of the partition through a bracket.
[0006] When using the nitrogen protective gas adding device with industrial oxygen compression safety control in the present technical solution, the staff must first connect the external power supply to the present invention and control the operation of the present invention through the control panel. The staff starts the oxygen compressor body, and the oxygen compressor body starts to run and draws external gas into it through the first pipe and the second pipe, and then compresses it to produce oxygen, and transports it to the inside of the device where it needs to be used through the third pipe. When a fire accident occurs during the operation or startup of the oxygen compressor body due to incomplete degreasing, cleaning or improper operation, the staff needs to stop the operation of the oxygen compressor body and control the reversing valve to switch the channel, close the channel between the first pipe and the second pipe, open the channel between the fourth pipe and the second pipe, and then control the first solenoid valve to open, so that the nitrogen in the first gas tank will be transmitted to the fourth pipe through the fourth pipe. The inside of the second pipeline is then transmitted to the inside of the oxygen compressor body through the second pipeline to fill the cylinder and other devices in the oxygen compressor body, so that the oxygen is cut off to achieve the purpose of rapid fire extinguishing. Then the staff also needs to open the second solenoid valve and the motor. After the second solenoid valve is opened, the nitrogen in the second gas tank will be transmitted to the inside of the shaft through the fifth pipeline, and then transmitted to the inside of the turntable through the shaft, and evenly transmitted to the two first nozzles and the two second nozzles through the turntable, and finally ejected through the first nozzle and the second nozzle, and the motor will rotate the first bevel gear fixed at the output end, the first bevel gear rotates the second bevel gear on the meshing surface, and the second bevel gear rotates with the shaft, so that the first nozzle and the second nozzle can spray nitrogen to the external side and internal surface of the bottom box, cutting off the oxygen and avoiding external fire.
[0007] Preferably, a motor is fixed to one end of the interior of the top box, a first bevel gear is fixed to the output end of the motor, and a second bevel gear is meshed with the surface of the first bevel gear. The motor, the first bevel gear, and the second bevel gear cooperate to rotate the shaft, thereby indirectly driving the two first nozzles and the two second nozzles to rotate.
[0008] Preferably, a shaft is rotatably mounted on the other end of the interior of the top box, a second bevel gear is fixed to the middle surface of the shaft, a turntable is fixed to the top end of the shaft, and a first nozzle and a second nozzle are connected to the side of the turntable. The first nozzle is longer than the second nozzle, and nitrogen gas ejected from the first nozzle can be sprayed onto the outer side of the bottom box, while nitrogen gas ejected from the second nozzle can be sprayed into the interior of the bottom box. In this way, oxygen can be cut off from both the exterior and interior of the bottom box to extinguish the fire.
[0009] Preferably, a rotary joint is connected to the bottom end of the shaft, which is connected to one end of a second solenoid valve via a fifth conduit. The other end of the second solenoid valve is connected to the output end of a second gas tank, which is located at the other rear end of the bottom box. The installation of the rotary joint ensures that the shaft does not rotate with the fifth conduit when it rotates, thereby achieving the effect of not affecting gas transmission while preventing the fifth conduit from rotating with the shaft.
[0010] Preferably, a first frame and a second frame are respectively provided at both ends of the rear end of the interior of the bottom box, and a first gas tank and a second gas tank are respectively placed inside the first frame and the second frame. The cooperation between the first frame and the second frame allows the first gas tank and the second gas tank to be placed inside, achieving the effect of providing a limited and stable placement position. The cooperation between the first gas tank and the second gas tank allows the interior and exterior of the oxygen compressor body and the bottom box to be covered with nitrogen, achieving the effect of covering with nitrogen to extinguish the fire.
[0011] Preferably, one side of the reversing valve is connected to a first pipe, and the other side of the reversing valve is connected to the input end of the oxygen compressor body via a second pipe. The oxygen compressor body is fixed to the other end of the inner front end of the bottom box, and the output end of the oxygen compressor body is connected to a third pipe. The provision of the reversing valve allows the incoming gas to be switched, achieving the effect of switching the pipeline path. The installation of the oxygen compressor body allows external gas to enter it for oxygen purification.
