Field of the Invention The present invention relates to a dust collecting electrode of a mobile electric precipitator and a method of manufacturing the same, and more particularly to dust in exhaust gas while moving the precipitating electrode. The present invention relates to a dust collecting electrode of a mobile electric dust collecting device for collecting and removing components (dust) and a method of manufacturing the same. 2. Description of the Related Art A dust collecting electrode of a mobile electric dust collecting apparatus is composed of a dust collecting electrode plate formed of a single iron plate and an edge member attached to the outer peripheral portion for reinforcement. It is configured. conventionally,
The dust collecting performance is improved by increasing the length of the dust collecting electrode plate in the gas flow direction. [0003] However, if the length of the dust collecting electrode plate is increased, the dust collecting electrode plate is likely to bend. Therefore, in order to increase the strength, the thickness of the edge material must be increased. Must. For this reason, on the contrary, there is a problem that the dust collection efficiency is reduced. Dust collection efficiency is proportional to the square of the apparent electric field strength between the electrodes. The apparent electric field strength is obtained by dividing the spark voltage by the distance between the discharge electrode and the dust collection electrode, and the spark voltage is determined by the shortest distance between the discharge electrode and the dust collection electrode. For this reason, when the thickness of the edge material is large, the distance from the discharge electrode is shortened accordingly, and the spark voltage is reduced. as a result,
The apparent electric field strength decreases, and the dust collection effect decreases. [0004] Further, depending on the thickness of the edge material, there is a problem that a stainless steel brush for scraping dust adhered to the dust collecting electrode is worn out early, and there is a problem that the scraped dust is located below. There is a problem that it accumulates in the edge material portion of the electrode plate. The present invention has been made in view of such circumstances, and has as its object to provide a dust collecting electrode of a mobile electric dust collector having high dust collecting performance and a method of manufacturing the same. [0005] In order to achieve the above object, the present invention provides an endless chain connected between a pair of endless chains.

The pair of dust collecting electrode plates are energized between the poles so that the reinforcing core material
It is characterized by spot welding. According to the dust collecting electrode of the present invention, the length of the dust collecting electrode plate can be increased because the pair of dust collecting electrode plates is attached with the reinforcing core material interposed therebetween. There is no longer any portion protruding from the surface. Therefore, the present invention can improve dust collection performance. Further, the dust collecting electrode of the present invention is manufactured by sandwiching a reinforcing core material between the pair of conductive electrodes for welding from both outer sides of the pair of dust collecting electrode plates, and conducting and welding between the pair of conductive electrodes. Have been. Thus, the pair of dust collecting electrode plates are symmetrically welded to the reinforcing core material, so that a stable positional shape can be maintained in the gas flow. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a dust collecting electrode of a mobile electric dust collecting apparatus according to the present invention and a method of manufacturing the same will be described below in detail with reference to the accompanying drawings.

The discharge electrodes 8 are provided between the 10. The dust collecting electrodes 10, 10,... And the discharge electrode 8 are connected to a DC power supply (not shown), and a DC voltage is applied between the electrodes. Dust in the exhaust gas flowing between the two electrodes is charged by corona discharge generated between the electrodes, and the dust collecting electrode 1 is charged.
Attach to 0, 10, ... and are collected. FIG. 2 is an enlarged perspective view of the dust collecting electrode 10, and FIG. 3 is an exploded perspective view of the dust collecting electrode 10. FIG.
As shown in FIG. 2, the dust collecting electrodes 10 and 10 are formed in a strip shape, and the longitudinal direction thereof is provided along the gas flow direction shown by the arrow in the figure. , 13. As shown in FIG.
The dust collecting electrode 10 includes two opposing dust collecting electrode plates 12 and 12 and a core material (reinforcing core material) to which the two dust collecting electrode plates 12 and 12 are attached. The core is composed of a pair of end members 18, two beams 16, 16 and a shaft 14. The pair of end members 18 are provided at both ends of the dust collecting electrode 10 in a vertical direction. The two beams 16 are provided horizontally along both edges of the dust collecting electrode 10, and both ends thereof are joined to the inside of the end members 18. The shaft member 14 is located in the middle of the two beam members 16, 16, and both ends thereof are the end member 1.
8 and 18 are joined to the inner central portion. Referring to FIG. 3, a method for manufacturing the dust collecting electrode 10 will be described. First, the shaft member 14 and the two beam members 16, 16
Both ends are joined to the inside of the pair of end members 18 by arc welding to assemble a core material. Next, the dust collecting electrode plates 12, 12 are welded to the assembled core material by spot welding. As shown in FIG. 4, in the spot welding, first, a pair of dust collecting electrode plates 12, 12 are arranged on both sides of the core material, and a core is formed from both outer sides of the pair of dust collecting electrode plates 12, 12. The material is sandwiched between a pair of welding electrodes 19, 19 on a coaxial line, and a current is supplied between the pair of welding electrodes 19, 19 to weld the pair of dust collecting electrode plates 12, 12 to the core material. According to this welding method, the welding conditions of the two opposite welding portions are the same, and the pair of dust collecting plates 1
The welding quality of Nos. 2 and 12 is the same. For this reason, since the left and right dust collecting plates 12 in the figure are symmetrically fixed to the core material, a stable positional shape can be maintained in the gas flow. In order to investigate the strength of welding, a tensile test was carried out in the two-sided sandwiching method described above, and in a single-sided two-point method in which a pair of welding electrodes 19, 19 were used to energize the two dust collecting electrode plates 12 between two points. Is shown in FIG. The left half in the figure is the result of the two-sided sandwiching method, and the right half in the figure is the result of the one-sided two-point method. In the drawing, the upper side 10 is a beam member 16 and the lower side 2 is a shaft member 14.
It was carried out about. When it is determined that welding is sufficient if the maximum load is 200 kgf or more, it has been found that the above-described double-side sandwiching method is more firmly welded to both the shaft member 14 and the beam member 16. The current flowing between the welding electrodes 19, 19 is 4800 A or more for the shaft 14 and 40 for the beam 16.
00A or more is preferable. The welding time is 11.5-12.
5 Hz is optimal . According to the present invention, the length of the dust collecting electrode plate can be increased because the pair of dust collecting electrode plates is attached with the reinforcing core material interposed therebetween. There is no portion protruding from the surface of the plate. Therefore, the present invention can improve dust collection performance. Further, according to the present invention, the reinforcing core material is sandwiched between a pair of conductive electrodes for welding from both outer sides of the pair of dust collecting electrode plates, and a current is supplied between the pair of conductive electrodes to thereby form the pair of dust collecting electrodes. The electrode plate is symmetrically welded to the reinforcing core, and can maintain a stable position and shape in the gas flow.
