Description

Technical Field

[0001] The invention relates to the technical field of negative pressure clean booths, in particular to a negative pressure clean booth with self-circulating dust removal. Background Art

[0002] A clean shed (also known as a simple dust-free room) is a workspace that can provide a local high-cleanliness environment. A clean shed is a simple clean room that is built in the fastest and most convenient way. A clean shed has a variety of cleanliness levels and space combinations and can be designed and manufactured according to usage requirements. Therefore, its main features are its ease of use, flexibility, easy installation, short construction period, and portability. A clean work shed can also be added to local areas of a general-level clean room that require high cleanliness to reduce costs. In the medical field, industrial field, physical and chemical field, etc., clean sheds are used to ensure the cleanliness of the air.

[0003] A clean shed with a Chinese patent application number of CN111648621B is formed into a closed space by combining upright poles, ring beams, top covers, convex blocks, antistatic glass and fixing strips, which is completely isolated from the outside world to form a sterile environment. The clean shed can be lifted by a lifting ring, a steel wire rope and a lifting ring, and the clean shed can be suspended and placed, or the pulling rod can be pulled out of the blind hole by the cooperation of the pulling rod and the blind hole, and the supporting rod can be rotated to rotate the supporting rod from a state parallel to the ground to a state perpendicular to the ground. The pulling rod pulled out of the blind hole is automatically rebounded and re-entered into the blind hole by a spring, and the clean shed is supported by the supporting rod, and the contact surface between the supporting rod and the ground is increased by a pressure relief plate, thereby increasing stability and reducing damage to the ground by the supporting rod. This clean shed has the effects of being suspended and supported on the ground at the same time, and can adapt to different environments. At the same time, when placed on the ground, the clean shed has the function of being waterproof and moisture-proof through a simple structure.

During the extraction process, the air inside the first clean room 1001 enters the second clean room 1002 through the return air port 1021, and then in this process, the air is removed by the atomizing device 11. The device 305 can extract the disinfectant liquid in the liquid storage tank 303 and then spray it out, so that the atomized disinfectant liquid can be sprayed on one side of the fixed frame 301, and the airflow passing through the return air port 1021 is disinfected, so that the inside of the second clean room 1002 is cleaner. The air extracted from the inside of the second clean room 1002 is sent to the inside of the air outlet 13 by the negative pressure turbine fan 11 through the connecting chamber 1003, and then sent to the air inlet 12 by the air outlet 13. When the air passes through the air inlet 12, the filter 207 inside the mounting frame 201 can filter the dust in the air, and then enters the first clean room 1001, thereby realizing the self-circulating dust removal effect and effectively preventing overflow.
