Example 1

As shown in figure 1, the utility model provides a bur sheet for electric precipitation, which comprises a bur part 1 and a fixing part 2, wherein the bur part 1 is connected with the fixing part 2, and the fixing part 2 is provided with a fixing hole.

Specifically, when the bur sheet is used, the bur sheet is fixed on the electric conductor through the fixing hole, the electric conductor can be a metal tube, a metal rod or a metal sheet and the like, has length, a plurality of bur sheets are distributed at intervals along the length direction of the electric conductor and are fixed on the electric conductor through the fixing hole, for example, the electric conductor is a metal round tube, and is inserted into the metal tube for fixing through the fixing hole through a bolt, so that the natural effect is realized, the interval between the bur sheets can be freely adjusted, and the inclination angle of each bur sheet can also be freely adjusted by adjusting the inclination angle of each fixing part 2 relative to the surface of the metal tube; compared with the common punching and integrally forming barbed wire, a virtual anode plate can be formed by adjusting the spacing between the barbed sheets and the inclination angle of the barbed sheets in a disordered arrangement mode of the barbed sheets (for example, when the common barbed wire is used, the barbed sheets are limited by structures, and the barbed sheets can only vertically and positively point to the anode plate to effectively remove dust, so that the barbed sheets point to the regions, and the anode plate is required to be arranged in the regions, but the adjustable barbed sheets used in the embodiment can enable the barbed sheets not provided with the anode plate regions to obliquely point to the anode plate), so that the area of the anode plate is reduced, and the weight of the electric dust collector is reduced.

The fixed part 2 is long-strip-shaped, and the number of the fixed holes is not less than two.

Specifically, the fixing part 2 is a rectangular conductive material (metal) sheet, a plurality of fixing holes are punched on the rectangular conductive material (metal) sheet, at least two fixing points are arranged, the position and the posture of the prickle sheet can be determined, and if only one fixing point is arranged, the prickle sheet can rotate.

As shown in fig. 2-5, the fixing holes include a first fixing hole 201 and a second fixing hole 202, the first fixing hole 201 is located between the barbed portion 1 and the second fixing hole 202; the fixing part 2 is fixed on the conductive rod 3, and the distance between the first fixing hole 201 and the second fixing hole 202 is larger than the outer width of the conductive rod 3.

Specifically, when the two prickle sheets are fixed, the two prickle sheets are symmetrical around the axis center of the conductive rod 3, namely, the two fixing parts 2 are respectively positioned on two side surfaces of the same position of the conductive rod 3, the first fixing hole 201 of the previous prickle sheet is coaxial with the second fixing hole 202 of the next prickle sheet, the second fixing hole 202 of the previous prickle sheet is coaxial with the first fixing hole 201 of the next prickle sheet, bolts are inserted into the coaxial two fixing holes for screwing, namely, the two prickle sheets are sleeved on the conductive rod 3, and the prickle parts 1 of the two prickle sheets respectively face to opposite directions; in the fixing mode, each conducting rod 3 is provided with a position of the prickle 101, and is provided with a group of prickle sheets with central symmetry, but the interval between every two groups of prickle sheets can be freely adjusted, the inclination angle of the prickle 101 of each group of prickle sheets can be adjusted by rotating the two fixing parts 2, so that all the prickles 101 are coplanar or disordered, because the conducting rod 3 is provided with the two prickle parts 1 and all the prickles 101 are not positioned on the same plane, the generated corona range is multidirectional, and the dust removal efficiency is higher than that of the common prickle 101 naturally; in addition, it should be understood that the number of fixing holes is not limited to the first fixing hole 201 and the second fixing hole 202, that is, the first fixing hole 201 and the second fixing hole 202 are defined for fixing, and if the outer width (diameter) of the conductor bar 3 is larger or smaller, two holes which are farther or closer in distance are taken among all the fixing holes, and the above-described fixing manner can be realized as new first fixing holes 201 and second fixing holes 202.

One end of the prickle part 1 is connected with the fixing part 2, and the other end of the prickle part 1 comprises at least two prickles 101.

Specifically, prickle portion 1 is the position that produces the corona, and prickle portion 1 is kept away from the one end of fixed part 2, is provided with a plurality of prickle 101, has the pointed end on the prickle 101 and is used for producing the corona.

As shown in fig. 1, the barbed portion 1 includes two barbs 101 and is respectively located on two sides of the barbed portion 1 along the width direction; the inner edges of the two barbs 101 are connected together to a U-shaped aperture 102.

Specifically, the prickle 101 end has two prickle 101 of symmetry, and every prickle 101 is the most advanced that two crossing sidelines are constituteed, and in these two crossing sidelines, the sideline in two outsides is the outer sideline of prickle portion 1 promptly, and the sideline in two inboards is connected with the sideline in U type hole promptly, and this kind of structure simple manufacture, and save material only need once simple punching press can dash out two prickle 101.

As shown in fig. 2 to 5, the junction of the barbed portion 1 and the fixing portion 2 has a bent portion.

Specifically, the bending portion does not need to be present when being manufactured, and can be bent as required after the bur sheet is fixed on the current-conducting rod; the bent part between the prickle part 1 and the fixing part 2 can help the prickle part 1 to adjust the inclination angle according to the installation requirement.

The fixing portion 2 has a bent portion at a position between the two fixing holes.

Specifically, because the burr piece uses, the corresponding setting of two burr pieces is in the both sides of conducting rod 3, and inserts four fixed orificess through two bolts and realize fixing, so, for example when conducting rod 3 is long round bar, the position extrusion an pitch arc flexion that lies in between two fixed orificess on the fixed part 2, can make the surperficial contact site of burr 101 and conducting rod 3 closely laminate, increase area of contact.

The prickle part 1 and the fixing part 2 are integrally formed, and the thickness of the prickle part 1 and the thickness of the fixing part 2 are not more than 0.5 mm.

Specifically, the burr piece material is 0.2mm thick 1Cr18Ni9Ti stainless steel, and burr portion 1 and fixed part 2 are two parts of a sheetmetal, and because the burr piece is whole very thin, so except that burr 101, the edge of burr piece also is a pointed end, also can produce the corona, compares in ordinary burr piece that the corona scope is bigger, and electric precipitation efficiency is higher.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the utility model has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
