Said papery secondary filter is provided with a papery inner filter core in the outer filter core of its papery.
Can find out from technological scheme of the present invention; Because prefilter of the present invention adopts the vortex air inlet and adds the powerful separation structure of rotatable fan; The air-flow that gets into prefilter is rotated along housing, utilize the centrifugal force of its generation, the dust bigger in the air-flow and the globule are separated; And be discharged to outside the sky filter, realized first order centrifugation.Show through test, first order centrifugation, its independent separation effect can reach more than 89%; The second level is axial flow cyclone tube prefilter, adopts 50 to 80 cyclone tubes according to different air input of engine by air.Utilize the vortex of its generation, further make the less grit that do not separated under the centrifugal force of air-flow and action of gravity and separate.Funnel shaped dedusting storehouse and dust discharge valve are adopted in its dust discharge, in time discharge so that isolated dust is not piled up.
Thereby, preceding two-stage do not use any filter screen to avoid blocked in the short time because separating big grit.After twice centrifugation filtrating equipment is set like this, in the mining area or the heavy goods vehicles of similar severe dust area operation, its air stream is to the end before the one-level papery secondary filter, and dust seldom.Reduced and maintained the more number of times of renew cartridge.The empty filter of third level papery is provided with outer filter core, inner filter core, and it mainly acts on is to intercept thin dust to get into motor.
Because of prefilter is provided with rain-proof cover, air induction mast, turbofan prefilter, dust exhaust port, steam outlet pipe etc., its profile is generally more elongated, and center of gravity is higher; As being rigidly connected with empty filter body; When the operation of jolting the mining area bigger, its amplitude of being clapped vibration is bigger, is prone to produce fatigue ruption and ruptures.The utility model adopts corrugated hose to be flexible coupling, and by anchor ear it is tightened, and whole prefilter is by the supporting frame load-bearing, and is installed on the car body in the lump with empty filter.The mounting bracket of empty on the other hand filter body is provided with the thick damping rubber cushion of 5-10mm.Vibration comparative trial through resonant frequency point shows: its vibration strength obviously improves more than 90%.
