The utility model is in order to solve the technological scheme that its technical problem adopts: the vertical erecting device of a kind of blower fan and combination of filters, comprise support platform, fan supporter, the first filter dunnage, the second filter dunnage, the filter scaffold, seal arrangement and hold-down mechanism, Vertical direction with blower fan air intake direction is a vertical direction, fan supporter is used for fixing blower fan, it is fixed positioned in storehouse, cleanroom plate open outer side, support platform just can be sheathed on the fan supporter outside, first of annular, tow filtrator dunnage outer side wall is fixedly arranged on respectively on the fan supporter madial wall, the first filter dunnage madial wall and the second filter dunnage are away from forming a filter installing space between the end wall of blower fan one side, filter scaffold (being used for fixing filter) just can be inserted in this filter installing space, the filter scaffold is positioned at two ends on the filter air intake direction and is respectively equipped with a seal arrangement of being made by elastic material, the sealing device presses closer first respectively, the tow filtrator dunnage is away from the end wall of blower fan one side, at least two hold-down mechanisms are symmetry status along the fan supporter shaft axis and are fixedly arranged on the fan supporter madial wall, the hold-down mechanism can regulate presses closer the filter scaffold away from blower fan one sidewall, described fan supporter sidewall is positioned at first, section is provided with some relief holes between the tow filtrator dunnage, when first, when the slit appears in sealing between tow filtrator dunnage and the filter scaffold, on the filter, air downstream pressure is greater than cleanroom's furred ceiling inner air pressure, this moment non-cleaning air be discharged to from the filter upstream along relief hole in cleanroom's furred ceiling, effectively prevent non-clean air contaminated filter device downstream the cleanroom; In the working procedure, hold down gag presses the filter scaffold, the filter scaffold presses first and second filter dunnage by seal arrangement, so just will be sealedly connected between filter scaffold and the fan supporter, prevent that the filter upstream air from leaking in the cleanroom, even and the air that sealing occur to be leaked the filter upstream also can be discharged in cleanroom's furred ceiling by relief hole, prevent that further the filter upstream air from leaking into internal contamination cleanroom, cleanroom air.
As further improvement of the utility model, the quantity of described hold-down mechanism is four, can make the filter scaffold stressed evenly, prevents that effectively the filter scaffold from causing not enough causing of seal arrangement sealing intensity to be leaked gas because of unbalance stress causes deflection.
As further improvement of the utility model, hold-down mechanism is a pair of cams, cam circumferencial direction is turned for this and axial retention is positioned on the fan supporter, inboard, following two ends, cam outer circumference face can press closer the filter scaffold away from blower fan one sidewall, rotating cam just can make the cam circle side face press closer or unclamp the filter scaffold, it is easy to adjust, the filter installation and removal are quick, hold out against reliable performance, the device that can realize this function also can be the screw bolt and nut cooperation, lead to the nut stationary positioned on fan supporter, on the madial wall of following two ends, hold out against or unclamp the filter scaffold by screwing or unscrew bolt.
As further improvement of the utility model, seal arrangement is a sealing gasket.
The beneficial effects of the utility model are: the utility model is in the sheathed support platform in the fan supporter outside, effectively prevent fan supporter run-off the straight and misplacing under action of gravity with filter, by hold-down mechanism and seal arrangement filter and fan supporter top tight sealing are in the same place again, the utility model adopts the secondary seal structure, the sealing of assurance filter, prevent that the cleanroom from leaking out, the fan supporter sidewall is provided with relief hole and can prevents effectively that the filter upstream air from leaking into the filter downstream and polluting clean indoor air simultaneously, and this erecting device is easy for installation, reliability is high.
