Description

Dynamic physical shielding purifier, manufacturing method and special fixture

BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a component for a dust removal air purifying device, and more particularly to a dynamic physical shielding purifier for physically removing particulate matter (containing solid particulate matter and liquid particulate matter) in an exhaust gas; a method of manufacturing a purifier and a special jig thereof. BACKGROUND OF THE INVENTION In the prior art, a dynamic physical shielding purifier currently used as a dust removing and purifying air device has two structures. One structure is a dynamic physical shielding purifier as shown in FIG. 8 , which includes a wheel skeleton 100 and a wire 110, the wire 110 is generally wound with a diameter of 0. 1-0. 2, wrapped around the wheel frame 100 according to certain requirements, the specific structure of the dynamic physical shielding purifier and The winding method can be referred to the Chinese patent document CN200984483Y and the Chinese patent document CN101028575A. The drawbacks of this type of dynamic physical shielding purifier are obvious. First, since the dynamic physical shielding purifier includes the wheel skeleton 100 and the wire 110, and the wheel skeleton 100 is made of an aluminum alloy material, the cost is high. In addition, each wheel frame 100 includes at least six or more spokes 111, and the spokes 111 itself may generate wind resistance to the air intake of the air device, affecting the purification rate of the air device; in addition, the wire of the dynamic physical shielding purifier The first wire, otherwise, the wire is not too thick, generally 0. 1- 0. 2 mm, otherwise, the wire is wound on the wheel frame 100, the wire is wound on the wheel frame 100, the diameter of the wire 100 is not too thick, generally 0. 1- 0. 2 mm, otherwise, the wire If the diameter of 100 is too thick, it will not be entangled. Secondly, due to the fineness of the filament 100, there will be a problem that the wire 100 of the purifier is easy to loose and break at high temperatures, resulting in a short service life of the purifier; When the wire 110 is wound, it will form a cross at the center of the purifier and the outer circle of the wheel skeleton, and the soot is easily clogged at the two places, which is difficult to clean. Since the fifth wire 110 is smaller, the probability of intercept particulate matter in the exhaust gas is small, so that purification is low, and poor adaptation narrow.

The structure of the second dynamic physical shielding purifier in the prior art, as shown in FIG. 9, is a method of punching a circular plate along the radial direction of the channel. 200, so that the two slots The portion becomes the spokes 210, and the plurality of spokes 210 are sequentially arranged on the circumferential surface of the plate. For details, see Chinese Patent Document CN2901109Y. This kind The main problem of the dynamic physical shielding purifier of the structure is that the purification rate is very low, the wind resistance is large, and the practical application function is very small. This is because the front surface 211 of the spokes 210 of the dynamic physical shielding purifier of this structure and its two side surfaces 212 are both flat. When the front surface 211 is a flat surface, the wind resistance is large, and the purifying rate of the purifier is lowered; In the plane, when the purifier rotates at a high speed, the side surface 212 generates pressure on the exhaust gas coming in from the direction of the front surface 211, and under the action of the side surface 212, the exhaust gas flows in the direction of rotation of the purifier, and the particulate matter in the exhaust gas and the spokes The chance of contact is small, so the purification rate is low.

The embodiment shown in Fig. 4 has the same general structure as the embodiment shown in Fig. 1, except that the metal spokes 13 are prefabricated into U-shaped spokes 15, and the open ends of the U-shaped spokes 15 are laser-coated. Soldered on the center disk 12. The two free ends of the U-shaped spokes 15 shown in Fig. 4 are in the same plane of the welding center disk 12. At this time, when calculating the product of the spoke diameter and the number of spokes, each U-shaped spoke 15 is calculated. .

Obviously, the two free ends of the U-shaped spokes 15 can be respectively welded on the planes of the two sides of the center disk 12 (not shown) to form the structure of the double-layered strips 13, so that both sides of a central disk 12 are There are as many spokes 13 as there are. In this case, when calculating the product of the spoke diameter and the number of spokes, each U-shaped spoke is 15 amps.

The laser welding in the present invention can also be replaced by other methods such as spot welding or gluing.

The diameter of the spokes 13 of the present invention is preferably set between 0.3 and 10 mm, and the value of the product of the diameter of the spokes and the number of spokes is preferably in the range of 46 or more and 460 or less. Its purification effect is the best. The theoretical and experimental basis for the relationship between the diameter of the spokes and the number of spokes in the present invention is as follows:

The basic function of the purifier 1 is to intercept and separate the particulate matter in the exhaust gas flowing through the purifier 1 during the movement, and the efficiency of the rotating purifier 1 intercepting the particulate matter in the exhaust gas is the spokes and exhaust gas of the purifier 1 The particle collision probability κ value. ,

And K= ( t./tw) χ ιοο% (Formula 1)

In the first formula: t. Is the time (in seconds) that the exhaust gas passes through the plane of operation of the spokes of the purifier 1;

t» is the time (in seconds) required for a single spoke to travel between two adjacent spokes; (seconds) (Equation 2)

In the second formula: D _w is the diameter of the spoke (mm);

₁₀ is the flow rate of the exhaust gas (mm/sec)

Tw= a /Uw ( ) (Formula 3)

In the third formula: a is the angle between the adjacent two spokes of the purifier 1 (week);

a = l / n (week), where n is the number of spokes on the same plane of the purifier 1;

U» is the motor speed (weeks per second) that drives the purifier 1 to rotate;

Substituting the second formula and the third formula into the first formula, after simplification, the following is obtained:

In practical applications, there are three types of commonly used motors that drive the purifier 1 to rotate: 650 weeks/minute (10.83 weeks/second); 1300 weeks/minute (21.67 weeks/second); 2900 weeks. / min (48. 33 weeks / sec).

Set the K value to 1 (ie 100%). When the motor speed is 650 cycles/min (10.83 cycles/sec), the flow rate of the exhaust gas is controlled within the range of 500-5000 mm/sec. D _w X The maximum value of n (that is, the product of the number of millimeters of the spoke diameter and its number) is 461, and the minimum value is 46. Similarly, when the motor speed is 1300 cycles/minute (21.67 weeks/second), the flow rate of the exhaust gas is controlled. In the range of 1000-10000 mm/sec, the maximum value of DWX n (ie the product of the spoke diameter and its number) is 461, the minimum value is 46; the motor speed is 2900 cycles/min (48.33 weeks/sec) When the flow rate of the exhaust gas is controlled within the range of 2200-15000 mm/sec, the value of D»X n is still in the range of 46 to 461.
