Description

Technical Field

[0001] The utility model belongs to the technical field of oxygen generators, and in particular relates to a completely oil-free micro-pressure oxygen generator. Background Art

[0002] In plateaus or places where a lot of oxygen is used, oxygen needs to be supplemented to increase the concentration of ambient oxygen, thereby improving people's comfort and work efficiency. The oxygen production equipment on the market is generally high-pressure oxygen production equipment (PSA). Although the non-integrated high-pressure oxygen production equipment has a large output, it is often fixed on the ground, which is not convenient to move and also has oil pollution; the integrated high-pressure oxygen production equipment has problems such as short equipment life, small oxygen output, and high noise.

[0003] The utility model with the authorization announcement number CN207361789U disclosed an integrated low-pressure oil-free oxygen generator, including a chassis, in which a Roots pump, a cooler, an adsorption tower, a balance tank and an oxygen buffer tank are arranged; the input end of the Roots pump is used to input air, and the output end is connected to the input end of the cooler through a pipeline, the output end of the cooler is connected to the input end of the adsorption tower bottom through a pipeline, the output end of the adsorption tower top is connected to the input end of the oxygen buffer tank through a pipeline, and the oxygen buffer tank is provided with an output pipeline for connecting the oxygen supply equipment; the balance tank is connected to the adsorption tower through a pipeline, and the pipeline is provided with a first solenoid valve; in the chassis, a soundproof cover is provided on the Roots pump. The utility model uses low-pressure oil-free oxygen production technology and sets an integrated structure to achieve its oil-free, low-pressure, integrated and low-noise functions.

[0004] The above technical solution structurally connects the pipe silencer to the Roots pump to reduce the noise in the Roots pump pipe. The gas in the soundproof cover can be discharged through the above exhaust port silencer, and the exhaust port silencer is arranged to reduce the noise generated by the Roots pump and prevent the noise from passing through the opening. In addition, by attaching sound-absorbing cotton on the inner wall of the chassis, it is helpful to reduce the overall noise inside the chassis. However, the above technical solution uses a cooler composed of a radiator and a fan to cool the compressed air. The fan accelerates the air flow on the surface of the radiator to cool the radiator, and finally cools the hot air inside the radiator. The cooling method of cooling by dispelling hot air will make the cooling process time longer and cannot quickly cool the gas. In addition, the above solution cannot completely exhaust the oxygen in the pipeline when collecting oxygen, and residual oxygen may occur, thereby causing a waste of resources.

[0027] In a specific embodiment of the utility model, through the coordinated use of the refrigerator 10 and the cooling tank 11, the gas can be quickly cooled down after passing through the inner cavity surface of the cooling tank 11, avoiding the current solution of accelerating the air flow on the surface of the radiator through the fan, cooling the radiator will make the cooling process time longer, and the gas cannot be cooled down quickly, thereby improving the efficiency of the completely oil-free slightly compressed oxygenation equipment. Through the setting of the vacuum pump 12, the gas in the outlet pipe 18 can be exhausted, avoiding the current solution that cannot completely exhaust the oxygen in the pipeline when collecting oxygen, and the possibility of residual oxygen, which in turn causes the problem of waste of resources, thereby improving the economy of the completely oil-free slightly compressed oxygenation equipment.

[0028] Specifically, a plurality of universal wheels 2 are installed at the bottom of the oxygen generator body 1, and brake pads are arranged on the surfaces of the universal wheels 2.

[0030] Specifically, the surfaces of the exhaust pipe 7 and the gas flow pipe 9 are both provided with pipe silencers, and sound insulation cotton 15 is provided between the outer shell and the inner cavity of the oxygen generator box body 1.

[0031] In a specific embodiment of the utility model, by providing a pipe silencer and sound insulation cotton 15, the noise generated when the equipment is in use can be reduced to avoid the impact of excessive sound on the user, thereby improving the comfort of the fully oil-free micro-pressure oxygenation equipment.

[0032] Specifically, there are two adsorption towers 16 , and check valves 17 are installed on the surfaces of the gas flow pipe 9 and the gas outlet pipe 18 .

The cooling tank 11 is kept in a low-temperature state through the setting of the refrigerator 10 and the cooling tank 11. When the gas passes through the inner cavity of the cooling tank 11, it can be quickly cooled. The cooled gas is adsorbed by the adsorption tower 16 to increase the purity of oxygen, and then flows into the oxygen storage tank 19. The setting of the check valve 17 prevents the gas from flowing back. When discharging oxygen, the oxygen discharge rate can be detected by the concentration sensor 13 and the flow controller 14, and then the gas discharge rate is adjusted through the control panel 5.
