Description
Technical field
The present invention relates to a kind of collecting plate of traveling electrode type electric dust collecting means, the collecting plate of the traveling electrode type electric dust collecting means that forms in the mode in rotary moving of the surrounding around discharge electrode of multi-disc collecting plate particularly linking with closed chain.
Background technology
In traveling electrode type electric dust collecting means 1, as shown in Figure 6 and Figure 7, the collecting plate 10 1 edge verticals that form dust collecting electrode move and rotate around discharge electrode 5, utilize on one side the high voltage that is applied to two interpolars to make dust charged and trapped by dust collecting electrode, utilize the brush 6 of being located at dust collecting electrode bottom that dust is stroked.Compared with the mode of beating that uses general fixed electrode type electric dust collecting means to carry out, dust peel off the minimizing of dispersing again bad or that dust flows backward, can bring into play higher control of dust.But owing to possessing the drive unit that collecting plate 10 is moved, and because of following reason, collecting plate needs firm structure, is therefore seeking simpler and cheap structure.
Dust collecting electrode is configured to, multiple collecting plates 10 that are in the horizontal direction strip are along vertical alignment arrangements, and two closed chain 14 suspensions that arranged at its horizontal direction two ends (two ends, left and right) and crawler belt shape ground is in rotary moving, at upper and lower side configuration sprocket 3,18,4,20, collecting plate 10 carries out rotary movement along the circumference of sprocket wheel.In this upset, collecting plate 10 becomes flat-hand position, and collecting plate 10 produces flexural deformation because of the weight of deadweight and the dust that adheres to.
Therefore,, in patent documentation 1, in order not cause flexural deformation or the buckling of collecting plate 10 plasticity, collecting plate 10 has adopted hollow box cross section or has strengthened into the structure of picture frame shape with the strength member of hollow.But, while there is production costs in such structure and installation cost increase problem.
Patent documentation 1:(Japan) No. 10-230187, Unexamined Patent
In order to make more at an easy rate the collecting plate 10 of above-mentioned hollow box structure, consider for example to reduce the method for steel plate thickness.Fig. 1 (A) represents that steel plate thickness is the figure of the part (junction surface of framework and steel plate) of the collecting plate of 0.8mm, Fig. 1 (B) represents that steel plate thickness is the figure of the part (junction surface of framework and steel plate) of the collecting plate of 0.4mm, if the thickness of attenuate steel plate 11, there are the following problems: in the fabrication stage, due to the bending impact at the position beyond the framework 12 of support that there is no deadweight, at the weld of framework 12 and steel plate 11, bending or fold are concentrated to steel plate 11, as shown in Fig. 1 (B), between framework 12 and steel plate 11, will produce gap 15.Like this, if collecting plate 10 exists gap 15, dust is just likely invaded and is accumulated in collecting plate 10 from this gap 15, the weight of collecting plate 10 is increased, and cause the distortion of collecting plate 10.
The weight increase of collecting plate 10 is related to increase and the sprocket wheel 3 of the driving electric power of dust collecting electrode, 18,4,20 or the wearing and tearing of the sliding part such as closed chain 14 increase, and, the distortion of collecting plate 10 causes the generation of the spark that the variation of the distance of separation of discharge electrode 5 and dust collecting electrode causes, and causes dust collecting performance to reduce.
Summary of the invention
Therefore, problem of the present invention is, even provide a kind of sheet metal also can not produce bending collecting plate structure and manufacture method thereof.
In order to solve above-mentioned problem, the collecting plate 10 of traveling electrode type electric dust collecting means of the present invention is configured to, by two overlapping mountings of rectangle steel plate 11 in the plane, after its upper and lower end parts being engaged by spot welding, between described two steel plates 11, form space, square framework 12 is inserted behind this space along its length, by spot welding, described two steel plates 11 and described framework 12 are engaged, be provided with for described collecting plate 10 is arranged on to the fastener 16 on described closed chain 14 at the both ends of described framework 12.
According to the collecting plate structure of traveling electrode type electric dust collecting means with feature as above, even sheet metal, also can engage under bending state not having, consequently, the joint of two steel plates 11 can not produce gap, can manufacture light weight and collecting plate 10 cheaply.

Detailed description of the invention
Fig. 2 is the top view that represents the summary of collecting plate 10 of the present invention, and Fig. 3 is the side view of collecting plate 10.Collecting plate 10 is configured to: the upper and lower end parts that along continuous straight runs is two steel plates 11 of strip engages by spot welding 13, the space of along its length framework 12 being inserted to the pars intermedia that is formed at two steel plates 11, and by spot welding, steel plate 11 and framework 12 are engaged, in the gap of the general triangular of the two sides of collecting plate 10, be welded in engagement sides sealing plate 17 on steel plate 11 in the mode of stopping up these gaps by point, and on the two ends of framework 12, be welded with the fastener 16 for engaging with closed chain (not shown).
By formation collecting plate 10 described above, utilize compared with the structure that strength member strengthens into picture frame shape with existing, can significantly reduce the weight of frame parts and the weight of steel plate and seek to reduce costs, and can prevent that dust from piling up on the framework on collecting plate top, cause the dust of piling up in the time that collecting plate overturns to disperse and outside dust arrester, spill and dust removal performance is reduced.
In addition, by the upper and lower end parts of steel plate 11 is engaged, also can increase the rigidity at this position, mechanical strength can be remained on compared with using the situation of framework to degree also in no way inferior.In addition, as shown in Figure 7, the elimination that is attached to the dust on collecting plate 10 is to be undertaken by embedding collecting plate 10 between two brushes 6 in rotation, because the upper and lower end parts of collecting plate 10 is formed as acute angle (with reference to Fig. 3), therefore the resistance can reduce to embed between brush 6 time, also has the effect that prevents that brush 6 from wearing and tearing or rolling over hair.
Below, the manufacture method of above-mentioned collecting plate 10 is described in further detail with reference to Fig. 4, as shown in Figure 4 (A), by overlapping sheet metal 11 surface that is positioned in on plane plate platform 21, staggered so that weld part exposes in the position of steel plate 11 and plate platform 21, and weld with mash welder 24
Next, as shown in Fig. 4 (B), the pars intermedia of two steel plates 11 that point is welded opens, and inserts framework 12 in this space, by spot welding, framework 12 and steel plate 11 is engaged.Now, the upper and lower end parts of steel plate 11, from the overlapping state of two steel plates shown in Fig. 5 (A), as shown in Figure 5 (B), applies power along the closed direction of upper and lower end parts (being left end in figure) of steel plate 11, prevents in steel plate 11 generation gap, junction each other.
Thereafter, insertion side, the gap sealing plate 17 of the general triangular forming in the two sides of collecting plate 10, is bonded together the composition surface of side seal plate 17 and steel plate 11 by spot welding.
Then, as shown in Fig. 4 (C), the fastener 16 that welding engages with closed chain in the both ends of the surface of framework 12.
In the above description, to fastener 16 illustrate have for closed chain 14(Fig. 7) carry out the structure of the fixing bolt hole of bolt, but be not limited to this, fastener 16 can be also be directly welded on closed chain 14 without hole shape.In addition, Fig. 4 (B), Fig. 4 (C) represent collecting plate 10 to erect the state coming, but also can collecting plate 10 are positioned under the state (level) on plate platform 21 and carry out as shown in Figure 4 (A).
