1. one kind with screen pack and can the air cleaning unit of noise reduction, comprise bracing frame (1), be arranged on the multiple air filtration pole units in support frame as described above (1), and be arranged on the air inlet passage (7) at bracing frame (1) bottom place, described air filtration pole unit comprises filter core cylinder portion section (9), the splined portion section (94) be coaxially fixedly connected with section (9) upper end, described filter core cylinder portion and the threaded portion section (93) be coaxially fixedly connected with section (9) lower end, described filter core cylinder portion, wherein, described filter core cylinder portion section (9) comprises along the distribution of its axis direction and the identical multiple fillter section unit of height on described axis direction, each fillter section unit be provided with in a circumferential direction at a distance of from 180 °

  • two gas permeability filter window (91) and with described two gas permeability filter window respectively in a circumferential direction at a distance of two air impermeability linkage sections (92) of 90 °

    , wherein, in two fillter section unit adjacent on described axis direction, upper fillter section unit gas permeability filter window (91) with under the air impermeability linkage section (92) of fillter section unit to aim in a circumferential direction or corresponding, wherein, each described air filtration pole unit is all arranged in respective overanxious post cover cylinder (8), described overanxious post cover cylinder (8) is provided with hollow out opening portion section (81) and shielding part section (82) at each interval along its axis direction, wherein, be provided with in a circumferential direction apart from the hollow out opening for exposing described gas permeability filter window (91) of 180 °

    in described hollow out opening portion section (81), described shielding part section (82) can shield the fillter section unit aimed at it, achieve a fixed connection by being fixedly connected on many horizontal connecting plates (83) at described shielding part section (82) place thus each described overanxious post cover cylinder (8) is fixed in place between described multiple air filtration pole unit and described overanxious post cover cylinder (8) and between described overanxious post cover cylinder (8) and support frame as described above (1), the top of described support frame as described above (1) is provided with the worm screw (51) in order to engage with multiple worm gear (52) being fixedly connected with splined sleeve (521) simultaneously driven by motor (5), each described splined sleeve (521) axially engages slidably with the splined portion section (94) of corresponding air filtration pole unit, the periphery of described motor (5) is provided with sound proof box (53) and is fixedly connected with described support frame as described above (1), the noise that described sound proof box (53) operationally produces in order to reduce described motor (5), described sound proof box (53) is made up of metal material also can play cooling effect, the upper side wall of described air inlet passage (7) is fixedly installed the multiple screw shells (6) with described threaded portion section (93) threaded engagement of corresponding air filtration pole unit, described air inlet passage (7) is connected with the screw shell (6) through correspondence and coordinates with the endoporus slipper seal in corresponding threaded portion section (93) thus air can be delivered to the multiple passage arms (71) in the inner passage (90) in corresponding described air filtration pole unit, the discharge duct (940) that is connected with the inner passage (90) in described air filtration pole unit is provided with in order to be discharged by the air after being filtered by multiple fillter section unit in described splined portion section (94), a screen pack (75) is provided with for filtering out particle larger in air and dust in described air inlet passage (7), described screen pack (75) is made up of metal material, thus, the threaded engagement of described screw shell (6) and described threaded portion section (93) make described motor (5) drive each described air filtration pole unit rise in the axial direction or decline the distance of height of described fillter section unit time, each described air filtration pole unit in the circumferential rotational angle is °
