Background technology

In the prior art, serve as the dynamic physical shielding purifier on the dedusting air cleaning device at present, two kinds of structures are arranged, a kind of structure is a dynamic physical shielding purifier as shown in Figure 5, it comprises wheel skeleton 100 and wire 110, described wire 110 general employing diameters are steel wire or the alloy silk of 0.1-0.2, be wrapped in described the wheel on the skeleton 100 by certain requirement, the concrete structure of this dynamic physical shielding purifier and winding method can be referring to Chinese patent literature CN200984483Y and Chinese patent literature CN101028575A.The defective of the dynamic physical shielding purifier of this structure is conspicuous, first because this dynamic physical shielding purifier comprises wheel skeleton 100 and wire 110, and wheel skeleton 100 is to make of aluminum alloy materials, its cost is higher, in addition, each is taken turns skeleton 100 and comprises spoke 111 more than 6 at least, and spoke 111 itself can produce windages to the air intakes of air assembly, influence the purifying rate of air assembly; In addition, the wire 110 of this dynamic physical shielding purifier is wrapped on the wheel skeleton 100, owing to wire 110 need be wrapped on the wheel skeleton 100, the diameter of described wire 100 can not be too thick, generally all be the 0.1-0.2 millimeter, otherwise wire 100 diameters too slightly just can't twine; Second because wire 100 is thinner, so the problem that the wire 100 of clarifier is at high temperature loose easily and disconnect can occur, causes the service life of clarifier short; The 3rd be since wire 110 when twining, it can form cross-like on the cylindrical of the center of clarifier and wheel skeleton, oil smoke very easily forms obstruction, not easy cleaning at this two place; The 5th is that so purifying rate is low, weak effect and adaptive surface are narrow because wire 110 is thinner, and its interception probability to the particle in the waste gas is less.

The structure of second kind of dynamic physical shielding purifier of the prior art, as shown in Figure 6, it is that method with punching press radially has groove 200 with a circular plate object along it, make the part between two grooves become spoke 210, a plurality of spokes 210 distribute successively on the periphery of plate object and form, and particular content can be referring to Chinese patent literature CN2901109Y.The subject matter of the dynamic physical shielding purifier of this structure is that purifying rate is low, and windage is big, and the practical application function is very little.This is that when front 211 was the plane, its windage was big, has reduced the purifying rate of clarifier because front 211 and two side 212 of the spoke 210 of the dynamic physical shielding purifier of this structure are the plane; And its side 212 is the plane, when clarifier rotates at a high speed, side 212 can produce pressure to the waste gas of coming in from positive 211 directions, under the effect of side 212, make waste gas along with the clarifier direction of rotation flows, and the contacted chance of particle in the waste gas and spoke is less, so purifying rate is low.

Summary of the invention

The purpose of this utility model provides a kind of simple in structure, low cost of manufacture, novel dynamic physical shielding device that purifying rate is high.

The technical solution of the utility model is: design a kind of novel dynamic physical shielding purifier, comprise spider and several circular spokes that are arranged in the same plane, described spoke one end is on the described spider of being fixed in of radial radiation, the long-pending value of the diameter of described spoke and the radical of spoke satisfies more than or equal to 46, smaller or equal to 460, wherein the diameter of spoke is unit with the millimeter, and the diameter of spoke is more than or equal to 0.3 millimeter.

Described clarifier also comprises a retainer plate, and the described spoke other end is fixed on the described retainer plate.

Described spoke is prefabricated into the U word shape, and its openend is fixed on the described spider.

Described affixed mode is welding, riveted joint or bonding and combination.

The utility model is compared with the dynamic physical shielding purifier that twines with wire, owing to saved the wheel skeleton, so cost is low, and has reduced windage, and has made its structure also become simpler; Since adopted many independent thicker circular spokes (diameter of spoke is more than or equal to 0.3 millimeter), be difficult for disconnecting or damaging, and the maintenance of this clarifier is also very convenient; Because this clarifier spoke need not twine, can not form cross-cutting issue so do not exist on the cylindrical of the center of clarifier and wheel skeleton, waste particulate material can not form obstruction at this two places utmost point, so cleaning is easy; The utility model is compared with the tabular clarifier of circle, because the utility model spoke is circular, so its front and side are curved surface, does not have the problems such as choke of circular tabular clarifier, so its purifying rate height.

The theory and the experimental basis of the spoke diameter in the utility model and the relation of spoke radical are as follows:

The basic function of this clarifier 1 is in motion process, and with the particle in the waste gas of the clarifier 1 of flowing through interception and separate, the particle interception in 1 pair of waste gas of the clarifier of rotation efficient is exactly the particle collision probability K value in clarifier 1 spoke and the waste gas.

And K=(t _Q/ t _W) * 100% (formula one)

In the formula one: t _QIt is the time (second) that waste gas passes through clarifier 1 spoke operation plane;

t _WBe that single spoke is in the required time (second) of the angle of stroke between two adjacent spokes;

t _Q=D _W/ U _Q(second) (formula two)

In the formula two: D _WIt is the diameter (millimeter) of spoke;

U _QIt is the flow velocity (mm/second) of waste gas

t _W=α/U _W(second) (formula three)

In the formula three: α is the angle angle of adjacent two spokes of clarifier 1;
