Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of purification workshop ventilation equipment, especially relates to a quick opening mechanism of emergency ventilation opening of purification workshop. BACKGROUND

[0002] In the running process of the purification workshop, it is crucial to keep the stability and safety of the air quality in the workshop. The traditional purification workshop ventilation system mainly focuses on daily air purification and circulation to meet the cleanliness requirements of the production process. However, when there is an emergency such as harmful gas leakage in the workshop, the existing ventilation facilities often have many shortcomings.

[0003] Many ventilation devices of the purification workshop lack a rapid detection and response mechanism for harmful gases. In the early stage of harmful gas generation, it is difficult to detect in time, thus delaying the best treatment opportunity, and the harmful gas spreads rapidly in the workshop, posing a serious threat to the health of the personnel in the workshop, production equipment and product quality. Even if part of the ventilation system has a detection function, after detecting the harmful gas, the opening speed of the ventilation opening is slow, and it is difficult to quickly change the ventilation direction and air volume to quickly and effectively exhaust the harmful gas from the workshop.

[0004] In addition, the traditional ventilation facilities are not flexible in structure design, and the sealing performance of the sealing parts may decrease after long-term use. It is difficult to achieve quick and reliable opening operation during emergency ventilation. At the same time, the key components inside the ventilation device, such as the motor and the fan, are not convenient to maintain and repair. Once these components fail, it is difficult to repair, and the entire ventilation system will be shut down for a long time, affecting the normal production and operation of the purification workshop.

[0005] In summary, in order to overcome the defects of the existing purification workshop ventilation system in emergency situations, it is urgent to provide a quick opening mechanism of emergency ventilation opening that can quickly detect harmful gases, quickly open the ventilation opening and efficiently exhaust harmful gases, and has the advantages of stable structure, convenient maintenance and the like, to ensure the safe operation and production continuity of the purification workshop in emergency situations.
