Above-mentioned middle provided a kind of compressed air aflter-fillter, its operation principle is: compressed air, from input port enters, is introduced into whirlwind leaf, has many angled breach on whirlwind leaf, forces air to produce strong rotation along cutting direction.Be mixed in like this inwall collision that airborne larger water droplet, oil droplet and dust etc. just obtain larger centrifugal force and village's water tumbler, separate and sink to water tumbler bottom from air, be a filter process herein.Then, gas is by middle filter core, and partial impurities, dust are filtered, and are secondary filter process herein.
As further technological improvement, the air flow channel in the notch lid junction of above-mentioned middle whirlwind leaf distributes in the shape of a spiral.This air flow channel that further improves spiral distribution in technical scheme can be increased in the centrifugal force that in its runner, larger water droplet, oil droplet and the dust etc. in ventilating air can obtain, the removal efficiency of the impurity such as larger water droplet, oil droplet and dust in lifting air.
As further technological improvement, the aflter-fillter in above-mentioned also includes water fender, and this water fender is positioned at the bottom of filter core, and is fixed by stretching screw equally.In above-mentioned further Technological improvement plan, water fender can prevent that the sewage accumulating in water cup from being rolled by gas whirlpool, causes compressed-air actuated secondary pollution.
As further technological improvement again, the bottom of above-mentioned middle water cup is provided with draining valve.In above-mentioned another step Technological improvement plan, the ponding of water cup bottom easily discharges, and promotes the operation convenience of aflter-fillter entirety.
The utility model obtains a kind of compressed air aflter-fillter, its good filtration effect, and leaching efficiency can reach more than 99%.
