Example Embodiment

[0014] The technical solutions of the present invention will be further described below through the accompanying drawings and embodiments.

[0015] The positive pressure filter air generator of the present invention includes a multi-stage dry air filter 1 , a centrifugal fan 2 and a hose 3 . The multi-stage dry air filter 1 is composed of cyclone guide vanes 4 , the second stage is a safety filter element 5 , the third stage is a main fine filter element 6 , a dust collection chamber 7 and a dust discharge closed port 8 . The cyclone guide vanes 4 and the air inlet casing form the first-stage cyclone separator.

[0016] The centrifugal fan 2 is powered on and the dust air is inhaled from the air inlet of the multi-stage dry air filter 1. The dust is separated by the first cyclone centrifuge of the multi-stage dry air filter 1, and the heavier dust particles move along the circular cavity. The wall flows down to the dust collection chamber 7, and the lighter dust is filtered b...

Abstract

The invention relates to a positive pressure filtration air generator which comprises a multistage dry air filter, a centrifugal fan and a hose. An air outlet of the multistage dry air filter is connected with an air inlet of the centrifugal fan; and an air outlet of the centrifugal fan is connected with the hose. The positive pressure filtration air generator has simple structure and reliable safety performance, is convenient to operate and has obvious effects of prolonging the service life of an electrical appliance and preventing the damage of dust to the electrical appliance.

Description

technical field [0001] The invention relates to a positive pressure dedusting and filtering air generator, which provides positive pressure and dust-free purified air for electric rooms (cabinets and boxes). Background technique [0002] Dust will reduce the service life of electrical equipment, and is also one of the causes of electrical fires, and more seriously, it will lead to explosion accidents. In order to prevent dust hazards, closed electrical rooms, cabinets, and boxes are usually used. Such electrical rooms, cabinets, and boxes have poor heat dissipation. , Often workers use compressed air to blow, which will cause a dust cloud. If it is a combustible dust cloud, it will explode when it encounters a fire source. Or use compressed gas to pass into the closed electrical room, cabinet, box, the dustproof effect is good, but the closed electrical room, cabinet, box structure is complicated, and the cost is high. Contents of the invention [0003] The purpose of th...
