Abstract
The invention discloses a low-efficiency air dust filter. The low-efficiency air dust filter is provided with a fixed blade with a swirling flow guiding function and a fin blade capable of rotary separation of dust and impurities at a high speed. According to the adopted scheme, the low-efficiency air dust filter comprises a semi-closed cylinder casing (1), the fin blade structure (5) capable of rotary separation of the dust and the impurities at the high speed, an inflow air swirling flow guiding device (8) and a double-bearing structure shaft (11). When outside air with the dust and the impurities enters the casing (1) from the bottom air inlet of the inflow air swirling flow guiding device (8) through swirling flow guiding blades (9), the formed swirling flow drives the inside fin blade structure (5) to conduct high-speed rotation, the dust and the impurities are discharged from a dust outlet (3) of the casing (1) under the function of poking pieces (7), and the pre-filtered air passes through a coarse filtration air outlet (10) and enters lower-stage filtration through a lower-stage filter connector (12). The low-efficiency air dust filter has the characteristics of being simple in structure, high in dust-removing efficiency and simple to maintain.

Further, described shell (1) side has dust-exhausting port (3), and described dust-exhausting port (3) opening direction is along shell wall corner cut side
To, under shell (1) along have location slightly (4) coordinate with described Inlet Swirl guider (8).
Further, the plectrum (7) that the described wing blade construction (5) of enclosure interior has arranged radially is some, wherein plectrum
(7) with shell inwall tangent plane be certain inclination angle.
Further, described Inlet Swirl guider (8) has the rotation by the band certain radian of certain inclination angle arranged radially
Conductance flow (9), is provided with described coarse filtration gas outlet (10) in the middle part of guider, bottom is provided with described lower level filter and connects
Mouth (12).
Further, described wing blade construction (5), Inlet Swirl guider (8) pass through dual bearing structure axle with shell (1)
(11) concatenation assembling, and wing blade construction (5) can under the effect of air swirl high speed rotating, rely on plectrum (7) effect will
Dust is discharged via dust-exhausting port (3).
The invention aims to improve and slightly imitate filter efficiency, lifting gas handling system usefulness, and reduce the loss of filter,
Extend life of product.
To achieve these goals, the technical solution used in the present invention is as follows: air-borne dust low efficient filter is mainly by four
Part composition, including rotational flow guide device, can the wing blade construction of high speed rotating separation dust impurity, band dust-exhausting port semiclosed
Barrel shrond, and concatenated the dual bearing structure axle being assembled together.
When the outside air with dust and impurity enters through dust filter unit bottom air inlet, through fixing in necessarily
The guide vane of inclination angle arranged radially, and form the eddy current of rotation, the wing blade construction high speed rotating within drive, at plectrum
Under effect, dust and impurity are discharged from the dust-exhausting port of shell, and pre-filtered air is turned back entrance coarse filtration gas outlet, and via under
Level filter interface enters subordinate and filters.
The present invention has a following Advantageous Effects:
The filter result of the application is simple, filter efficiency is high, it is easy to maintenance to clear up, be particularly well-suited to high dust, big
The air coarse filtration of the environment such as grain.
