It is sucked into air filtration room.The channel plate of partition board is provided perpendicular on partition board, if on channel plate set dry passage, when gas from
When air entry enters air filtration room, a part of gas is directly impinged upon on channel plate, and the direction of air-flow easily changes, but the grains of sand because
The effect of inertia force, it is impossible to as air-flow changes direction, after sand dashed sand is on channel plate, detach, be fallen in partition board with gas
On, it is entered in the husky room of collection by the sand discharge hole on partition board；In channel on a part of gas inlet passages plate, in channel by
Reduce suddenly in the flow area of gas, gas flow rate increases, and the mean free path of gas reduces, the grains of sand entrained by gas it
Between collision and the grains of sand and vias inner walls between collision frequency increase, reduce the kinetic energy of the grains of sand, collided each time
Cheng Zhong, the kinetic energy of the grains of sand continuously decrease, and can not slide out channel with gas by channel along vias inner walls later, finally lead to
Sand discharge hole is crossed to drop down onto in the husky room of collection；Some gas carries a small amount of grains of sand by channel, this portion gas is from high pressure
Side enters low-pressure side, due to the resistance of channel, forms turbulent flow in awave expansion at once after by channel and flow velocity subtracts
Slowly, although and solid by channel, its flow direction is advanced, along with sand no longer with gas to exhaust pipe by channel change
The grain gravity of itself during exhaust pipe is gone to, is gradually dropped down onto on partition board and is collected in the husky room of collection.Preferably,
In order to reduce the grains of sand amount that gas is taken out of from the husky room of collection, a sand discharge hole is only set on partition board.The gas filtered by channel plate

It is numerous to collide.Channel and horizontal plane are provided with angle, not only so that the grains of sand enter after channel there are one incidence angle, allow the grains of sand with
Vias inner walls collide, and change its moving direction, moreover it is possible to make the grains of sand kinetic energy reduction after can be slid along vias inner walls to every
On plate.
Further, angle is 5~20 °.It is found by putting into practice, when angle is less than 5 °, passes through the gas after channel class
The grains of sand of middle carrying are more, do not meet pre-filtered requirement；When angle is more than 20 °, the flowing of gas is hindered, channel plate
The pressure difference increase of both sides, air compressor machine occurs can not air-breathing or the phenomenon that slow breathing process.
Further, the distance of channel plate to openend is channel plate to 1.5~2.5 times of blind end distance.Channel plate
Length to openend is in order to which gas is made to have enough distances to accelerate to certain speed after air entry entrance, is had certain
Kinetic energy reaches gas after channel plate is hit and forms preferable separating effect with the grains of sand；The distance of channel plate to blind end be for
So that gas and the grains of sand from channel by rear, gas can restore from turbulent flow to regular laminar condition, and grains of sand energy
It after lateral kinetic energy slows down, is gradually dropped down onto by gravity in the sand discharge hole on partition board, is found by putting into practice, channel plate is to opening
During 1.5~2.5 times for channel plate to blind end distance of the distance at mouthful end, air filtration room has higher except grains of sand ability.
