The device uses the conductive metal plate to form porous circular holes in a die cut way, and the conductive metal plate is used as a dust collecting electric plate for filtering the air and the dust. Because the dust collecting electric plate has even micro electric discharge, the dust collecting efficiency can be provided.

Description

The high pressure dust collecting electric plate

The utility model relates to a kind of high pressure dust collecting electric plate, and especially a kind of the utilization is die-cut into the porous toroidal on the conductive metal sheet, as the dust collecting electric plate of filtered air dust.

Existing in the market electronic type collecting plate is the air intake vent place that is placed on air conditioner, cold (warming up) mechanism of qi or air cleaner etc., see also Fig. 5, it is interlocking one conductive metal sheet (anode dust collecting electric plate) 70 and one needle electrode plate 80, the wherein die-cut ordered series of numbers square opening 71 that is provided with on conductive metal sheet 70 in regular turn on the periphery of the framework 60 that is hollow; And in needle electrode plate 80 correspondences on square opening 71 RC positions, respectively be provided with a spray point (cathode needle end) 81.

Collecting plate mainly utilizes DC high pressure trace discharge principle, is negative electrode with needle electrode plate 80, is anode with the conductive metal sheet 70 of porous square shape, and spray point end 81 is positioned at square opening 71 positive centers.When high-voltage dc voltage in addition between needle electrode plate 80 and conductive metal sheet 70 the two poles of the earth systems, this voltage unlikely generation spark under the state of normal temperature, normal pressure is seen micro-lilac corona in that dark place is next, and this is so-called trace discharge;

When between needle electrode plate 80 and conductive metal sheet 70 the two poles of the earth, applying high pressure, the negatron that is discharged towards conductive metal sheet 70 by spray point end 81 can be attached to the dust granules by interpolar, and make dust granules also electronegative, this electronegative dust granules is adsorbed on the conductive metal sheet 70, and reaches the effect of peace and quiet air.

Because the distance around the spray point square shaped hole 71 does not wait, all discharge needle points 81 are inhomogeneous to the electric-field intensity that square opening 71 produces all around, the ability that smashes suspended particles a little less than, therefore utilize and be die-cut into the porous square shape on the conductive metal sheet, as the dust collecting electric plate of filtered air dust, its dust catching efficiency is low.

Main purpose of the present utility model provides a kind of high pressure dust collecting electric plate, and the electric-field intensity of its discharge is even, and the ability that smashes suspended particles is stronger.

The purpose of this utility model is achieved in that a kind of high pressure dust collecting electric plate, and it is by framework, the conductive metal sheet of interlocking on the architrave of frame-saw frame of the square deckle board that is hollow, and interlocking is formed in framework both sides inner face needle electrode plate.The die-cut ordered series of numbers circular port that is provided with on the wherein said conductive metal sheet is arranged with at least one small sircle hole on the appropriate location of contiguous each circular port; Corresponding on the RC position of the circular port of conductive metal sheet, be respectively equipped with a discharge needle point on the described needle electrode plate, discharge needle point to the week circle of circular port keeps equal spacing.

Before or after conductive metal sheet, can install a filter screen.

The utility model high pressure dust collecting electric plate, it utilizes conductive metal sheet to be die-cut into the porous circular hole, as the dust collecting electric plate of filtered air dust, because dust collecting electric plate has trace discharge uniformly because of it, so dust catching efficiency can be provided.

The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiments.

Fig. 2 is the constitutional diagram of this wound.

Fig. 3 is the enforcement illustration of A the utility model part.

Fig. 4 is another exploded view of the present utility model.

Fig. 5 is the schematic diagram of electronic type collecting plate structure of the prior art.

See also shown in Figure 1ly, a kind of high pressure dust collecting electric plate of the utility model comprises members such as a conductive metal sheet (anode dust collecting electric plate) 1, needle electrode plate (cathode electrode plate) 2 and a framework 3.As shown in Figure 1, 2, framework 3 is one to be the square deckle board of hollow, be respectively equipped with not equidistant screw 31 on the architrave around it, one conductive metal sheet 1 can be integral with the deckle board interlocking respectively by several interlocking elements (as screw) 32, two medial surfaces at framework 3 are respectively equipped with at least one double-screw bolt 33, needle electrode 2 is integral with the deckle board interlocking, and needle electrode plate 2 is positioned at a side of conductive metal sheet 1.

Conductive metal sheet 1 plate body that is square, on the position corresponding to framework 3 screws 31 on it, respectively be provided with a lockhole 10, conductive metal sheet 1 can be integral by lockhole 10 and framework 3 interlockings, and cut the circular port 11 that is provided with ordered series of numbers on conductive metal sheet 1 top, be respectively equipped with at least one small sircle hole 111 on contiguous each circular port 11,, reduce windage as to suck the by-pass prot of air.

Needle electrode plate 2 plate body that is rectangle, on the position corresponding to framework 3 double-screw bolts 33 on it, respectively be provided with a screw 20, screw 20 such as can pass respectively with interlocking element (as screw) 22 and be integral with framework 3 interlockings, on the circular port 11 RC positions of needle electrode plate 2 corresponding to conductive metal sheet 1, be respectively equipped with a discharge needle point 21, discharge needle point 21 to the week circle of circular port 11 keeps equal spacing, because discharge needle point 21 to the distance of circular port 11 equates, all discharge needle points 21 are even to the electric-field intensity that circular port 11 produces all around, the ability that smashes suspended particles is stronger, therefore its dust catching efficiency good (it experiment showed, under identical high voltage and identical collecting plate external form can improve dust catching efficiency more than 15%).

Wherein the number of conductive metal sheet circular port can change to some extent according to the size of machine.

When between needle electrode plate 2 and conductive metal sheet 1 the two poles of the earth, applying high-voltage dc voltage, because the electronegative son that discharges towards conductive metal sheet 1 of discharge needle point 21 can be attached on the dust granules by interpolar, and make it also electronegative, this electronegative dust granules is adsorbed on the conductive metal sheet 1 of positively charged, and reach the effect of air cleaning, as shown in Figure 3.

See also shown in Figure 4ly, the utility model can install a filter screen that is square 5 in conductive metal sheet 1 back (or preceding), to filter dust, cotton-wool, impurity and absorption, decomposition peculiar smell etc.
