Abstract
The utility model relates to a stainless steel negative pressure isolator, which comprises a casing body and a door which is arranged on the casing body, wherein an air-supply passage and an air-outlet passage are arranged in the casing body. An air feeder and air supply filtering system are arranged in the air-supply passage, and an air-outlet machine and an air-outlet filtering system are arranged in the air-outlet passage. The inner wall of the casing body on the inner side of the door is provided with a negative pressure air outlet pipe which is extended along the longitudinal direction of the door, and the negative pressure air outlet pipe is communicated with the air-outlet passage, and a plurality of air-outlet holes are arranged n the negative pressure air outlet pipe. When the door is opened, gas gets into the negative pressure air outlet pipe from the air outlet holes, and then the gas is discharged into the air-outlet passage, gas leakage can be effectively avoided, and security is higher.
Description
Technical field
The utility model relates to a kind of stainless steel negative pressure isolator.
Background technology
In the prior art, usually be provided with door on the housing of negative pressure isolator, but to make things convenient for the staff to open behind the door letting animals feed or to experimentize, shut and prevent that behind the door viral gas from leaking, and be provided with plenum chamber in the housing and go out air compartment, so that give animal clean new wind, and for safety, the indoor filtration system that is equipped with of plenum chamber and air-out is to stay virus in the housing.But because the air outlet of the exhaust vent that goes out air compartment and animal feeding case is apart from far away, when the staff opened, gas just can leak out, and surrounding environment has been caused pollution, and the staff is infected.
Summary of the invention
The utility model purpose provides a kind of stainless steel negative pressure isolator, when it is opened at door, can prevent that gas from leaking.
For achieving the above object, the technical solution adopted in the utility model is: a kind of stainless steel negative pressure isolator, and comprise housing, be arranged on the door on the described housing, have air-supply passage and air-out passage in the described housing.Be provided with pressure fan and powered air-purifying system in the described air-supply passage, be provided with out blower fan and air-out filtration system in the described air-out passage.The inwall of the housing that described door is inboard is provided with along the negative pressure wind pipe of the longitudinal extension of door, has a plurality of exhaust vents on the described negative pressure wind pipe, and described negative pressure wind pipe is connected with the air-out passage.
Because technique scheme utilization, the utility model compared with prior art has following advantage: the inner walls of door inboard is provided with the negative pressure wind pipe, on the negative pressure wind pipe, have a plurality of exhaust vents, when opening, gas promptly enters in the negative pressure wind pipe from exhaust vent, enter the air-out passage then, can prevent effectively that gas from leaking, security is higher.

The specific embodiment
Referring to accompanying drawing 1-accompanying drawing 4, a kind of stainless steel negative pressure isolator comprises housing 1, is arranged on the door 2 on the described housing 1, has air-supply passage and air-out passage in the described housing 1, and described air-supply passage is positioned at the top of described housing 1.Be provided with pressure fan 5 and powered air-purifying system in the described air-supply passage, be provided with out blower fan 9 and air-out filtration system in the described air-out passage.The inwall of the housing 1 of described door 2 inboards is provided with along the negative pressure wind pipe 3 of the longitudinal extension of door, has a plurality of exhaust vents 4 on the described negative pressure wind pipe 3, and described negative pressure wind pipe 3 is connected with the air-out passage.
Referring to accompanying drawing 2-accompanying drawing 3, accompanying drawing 5, have the housing inner chamber in the described housing 1, and the top of described housing inner chamber is provided with top board 14, have a plurality of fresh air inlets 15 on the described top board 14, described fresh air inlet 15 is connected with described air-supply passage.
When door 2 is opened, because the effect of negative pressure wind pipe 3 makes gas enter in the negative pressure wind pipe 3 from exhaust vent 4 immediately, and then enter in the air-out passage that it is indoor to avoid viruliferous gas to leak into, and has improved security.
Referring to accompanying drawing 2, described powered air-purifying system comprises first low efficient filter 6, first high efficiency particulate air filter 7.Referring to accompanying drawing 3, described air-out filtration system comprises second high efficiency particulate air filter 10, second low efficient filter 12.Described air-out filtration system also comprises the 3rd high efficiency particulate air filter 11, and described the 3rd high efficiency particulate air filter 11 and second high efficiency particulate air filter 10 are in series.By a plurality of low efficient filters and high efficiency particulate air filter, virus can be isolated in this negative pressure isolator, thereby avoid poisonous gas contaminated air in spite of illness, more effective human infection virus that prevents.
