Description

Technical Field

[0001] The present invention relates to the technical field of negative pressure clean booths, and particularly to a negative pressure clean booth with self-circulating dust removal. Background Technique

[0002] A clean booth (also known as a simple clean room) is a working space that can provide a locally highly clean environment. A clean booth is a simple clean room that can be established most quickly and conveniently. The clean booth has various cleanliness levels and space configurations and can be designed and manufactured according to usage requirements. Therefore, its main features are simple operation, large flexibility, easy installation, short construction period, and portability. The clean working booth can also be locally added in areas that require high cleanliness in a general-class clean room to reduce costs. In the medical field, industrial field, physical and chemical field, etc., clean booths are used to ensure the cleanliness of the air.

[0003] In a clean booth with the Chinese patent application publication number CN111648621B, it is composed of vertical poles, a ring beam, a top cover, bumps, anti-static glass, and fixing strips to form a sealed space, completely isolated from the outside world to form a sterile environment. The clean booth can be lifted by hanging rings, steel wires, and hanging rings and suspended, or through the cooperation of a pull rod and a blind hole, the pull rod is pulled out of the blind hole, the support rod is rotated, and the support rod is rotated from a state parallel to the ground to a state perpendicular to the ground. The pull rod pulled out of the blind hole automatically rebounds and re-enters the blind hole through a spring, and the clean booth is supported by the support rod. The contact surface between the support rod and the ground is increased by a pressure-reducing plate to increase stability and at the same time reduce the damage of the support rod to the ground. This clean booth has the effects of both hanging and supporting on the ground, can adapt to different environments, and has the functions of waterproofing and moisture-proofing through a simple structure when placed on the ground.

Then, the negative pressure turbine fan 11 is installed in the communication room 1003. During use, the personnel or objects to be dust-removed are placed in the second clean room 1002. The negative pressure turbine fan 11 operates to extract the air inside the second clean room 1002. During the extraction process, the air inside the first clean room 1001 enters the second clean room 1002 through the air return port 1021. During this process, the atomizing device 305 can extract and spray the disinfection liquid inside the liquid storage tank 303, so that the atomized disinfection liquid can be sprayed on one side of the fixing frame 301 to disinfect the airflow passing through the air return port 1021, making the inside of the second clean room 1002 cleaner. The air extracted from the inside of the second clean room 1002 is sent to the inside of the air outlet pipe 13 by the negative pressure turbine fan 11 through the communication room 1003, and then sent to the air inlet 12 by the air outlet pipe 13. When the air passes through the air inlet 12, the filter screen 207 inside the mounting frame 201 can filter the dust in the air, and then enter the first clean room 1001, so as to achieve the self-circulation dust removal effect and effectively prevent spillage.
