Abstract
The utility model discloses an oxygenator with low de-nitrogen noises. The oxygenator comprises a machine body, an air compressor and an adsorption tower, further comprises a de-nitrogen silencing system, wherein the air compressor and the adsorption tower are arranged in a machine case, respectively; silencing cotton is adhered on the inner wall of the machine case; the de-nitrogen silencing system comprise a first silencer and a second silencer, wherein a gas inlet of the first silencer is connected with an upper cover of the adsorption tower; the second silencer is arranged in the machine case of the air compressor, and connected with a gas outlet of the first silencer by a pipeline. Nitrogen gas exhausted from the adsorption tower enters the first silencer from the upper cover of the adsorption tower for finishing primary silencing treatment, and then enters the second silencer for carrying out the secondary silencing treatment, and is finally exhausted; and the adsorption tower and the air compressor are arranged in the machine case which is adhered with the silencing cotton on the inner wall. The oxygenator with the low de-nitrogen noises has the advantages of being low in de-nitrogen noises and the like.
Description
Technical field
The utility model belongs to technical field of medical instruments, is specifically related to a kind of medical oxygenerator.
Background technology
Existing medical oxygenerator can produce big noise in oxygen processed, can impact user or patient's rest.The reason that oxygenerator produces a large amount of noises is: 1, air compressor pressurized air; 2, adsorption tower denitrogen.The noise that produces when avoiding oxygenerator to produce oxygen is excessive, and existing oxygenerator connects a noise reduction container at adsorption tower usually, and nitrogen is emitted on oxygenerator inside after through the noise reduction container.Yet above-mentioned processing mode still can not effectively solve the big problem of oxygenerator noise, and its noise reduction treatment effect is limited.
Summary of the invention
At the deficiencies in the prior art, the utility model aims to provide the low oxygenerator of a kind of denitrogen noise, can not influence user or patient during work and have a rest.
For achieving the above object, the utility model adopts following technical scheme:
The low oxygenerator of a kind of denitrogen noise comprises body, air compressor, adsorption tower, also comprises a silene system, and described air compressor is installed in first cabinet, and adsorption tower is installed in second cabinet; Described silene system comprises first sound damper and second sound damper, wherein the first sound damper inlet mouth is connected with the outlet of adsorption column top cover denitrogen, second sound damper is installed in first cabinet, the second sound damper inlet mouth and the first sound damper air outlet are by pipe connection, and second sound damper also is provided with the nitrogen venting port.
The described first sound damper inside is provided with wool felt and PU foam.
The described second sound damper inside is provided with wool felt and PU foam.
The described first cabinet inwall posts acoustical cotton.
The described second cabinet inwall posts acoustical cotton.
The described first cabinet top is provided with venting port, installs and fixes a vent fan on the venting port.
The utlity model has following beneficial effect:
After nitrogen is handled through twice noise reduction in the utility model adsorption tower, blow to the oxygenerator outside through fan, and its air compressor and adsorption tower all be installed on inwall and post in the cabinet of acoustical cotton, have advantages such as good muffling effect, noise are little.
Description of drawings
Fig. 1 is the structural representation of the low oxygenerator of a kind of denitrogen noise of the utility model.
Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model will be further described, so that clearerly understand the claimed technological thought of the utility model.
As shown in Figure 1, the present embodiment oxygenerator, comprise body 1, an air compressor 2, an adsorption tower 3 and a silene system, wherein air compressor 2 is installed on first cabinet, 51 inside, post acoustical cotton around first cabinet, 51 inwalls, acoustical cotton is mainly used in absorbing the noise that compressor pressurized air makes generation, and first cabinet, 51 upper ends also have venting port, install and fix a vent fan 6 on the venting port, vent fan 6 is used for and will blows out and send outside the oxygenerator through the nitrogen that noise reduction is handled.Adsorption tower 3 is installed on second cabinet, 52 inside, also posts acoustical cotton around second cabinet, 52 inwalls.Described silene system comprises first sound damper 41 and second sound damper 42 respectively, first sound damper 41 and second sound damper, 42 inside are provided with wool felt and PU foam, the wherein denitrogen of fixedly connected adsorption tower 3 loam cakes of first sound damper, 41 inlet mouths outlet, first sound damper, 41 air outlets and second sound damper, 42 inlet mouths pass through pipe connection, second sound damper 42 is fixed in first cabinet 51, also is provided with the venting port 42-2 that discharges for nitrogen on second sound damper 42.
The principle of work that the utility model denitrogen noise is low is: nitrogen enters in first sound damper 41 through after the noise reduction from the denitrogen outlet of adsorption tower 3 loam cakes, enter second sound damper 42 by connecting tube and carry out secondary noise reduction processing, last nitrogen is discharged from second sound damper, 42 venting port 42-2, and blows out by fan 6 and to deliver to the oxygenerator outside.
For a person skilled in the art, can make other various corresponding changes and distortion according to technical scheme described above and design, and these all changes and distortion should belong within the protection domain of the utility model claim all.
